Description
BACKGROUND OF THE INVENTION
The present invention relates generally to improvements in food
dispensing devices, and it relates more particularly to an improved
automatically timed animal food dispensing device.
In the proper care and tending of pets, such as cats and dogs and
other animals, it is generally necessary that drinking water be
always available, and that food be made available at regular
intervals. However, in the case of household confined animal pets,
it is often inconvenient and frequently impractical to attend to
the animals feeding needs at the proper and optimum times by the
reason of the absence of anybody to attend to these needs at such
times. Many devices have been heretofore employed and proposed for
automatically making food available to an animal at a preset time,
but such devices possess numerous drawbacks and disadvantages. They
are generally complex and unreliable, of limited application, of
little versatility and adaptability, and otherwise leave much to be
desired.
SUMMARY OF THE INVENTION
It is a principal object of the present invention to provide an
improved dispensing device.
Another object of the present invention is to provide an improved
animal feeding device.
Still another object of the present invention is to provide an
improved device for storing food for an animal, and for
automatically making it accessible at a preset time.
A further object of the present invention is to provide a timed
animal food dispensing device in which an audible signal is
produced with the dispensing of the food, and in which other animal
services are furnished, including an improved automatic water
filling trough, animal playthings, mats, shelters and the like.
Still a further object of the present invention is to provide a
device of the above nature characterized by its reliability, great
versatility and adaptability and ease and convenience of use.
In a sense the present invention contemplates the provision of an
improved, timed animal feeding device, comprising a food
receptacle, a housing enclosing the food receptacle, and including
an access member moveable between a first position providing access
to the food receptacle and a second position preventing such
access, means biasing the access member to its first position, a
latching member moveable between a position locking the access
member in its second position, and a position releasing the access
member, a clock supported by the housing and including a spring
wound alarm motor having a winding shaft rotatable in opposite
first and second directions, with the loading of the motor spring
and with the unwinding of the spring to sound the alarm
respectively, and adjustable alarm time setting means, and latch
control means responsive to the rotation of the motor shaft in the
first for permitting the movement of the latch member to its lock
position, and to the rotation of the shaft in the second direction
for shifting the latch member to its release position.
In its preferred form, the improved device includes a cabinet
having a hinged door spring biased to an open position and linked
to a food receptacle carrying slide plate which is withdrawn from
and retracted into the cabinet with the opening and closing of the
door. A latch control and winding member is coupled to the alarm
motor for rotation about a vertical axis and the latch member is a
slide rod vertically moveable into and out of engagement with a
socket carried by the door and the latch control member and latch
member are associated by a cam and follower to raise the latch
member with the unwinding of the shaft and to lower the shaft
member with the opposite turning of the control member to wind the
alarm motor. A closed water tank is housed in the cabinet and its
bottom is connected by a flexible tube to the bottom of an external
water trough and a vent pipe connects the upper parts of the tank
and trough. Also, associated with the cabinet is an extendable mat
or shelter and an animal play device.
The improved device is reliable, of great versatility, and
adaptability, and easy and convenient to use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, particularly FIGS. 1 to 8 thereof,
which illustrate a preferred embodiment of the present invention,
the reference numeral 10 generally designates the improved feeding
and drinking device which comprises a floor supported cabinet 11,
including rectangular horizontal top and bottom walls 12 and 13,
opposite rectangular side walls 14 and 16, a read wall 17, and
being open at its front to define an access opening 18. The bottom
wall 13 is provided with depending rubber foot pieces 15. A
rectangular door 19 is connected by hinges 20 to the front edge of
wall 16 for swinging between a closed position engaging shoulders
in the wall edges delineating access opening 18 and a fully opened
forwardly extending position, as shown in FIGS. 1 and 4.
A resiliently, forwardly biased door opening vertical plate 21,
having an opening 22, is disposed proximate the inside face of door
19 and is mounted by a pair of vertically spaced hinges 23, mounted
in blocks 24 to the inside face of the front vertical border of
side wall 16 to be swingable about a vertical axis, inwardly,
rearwardly offset from that of hinges 20. A pair of hair pin
springs engage the pins of hinges 23 and have legs bearing on the
faces of the leaves of hinges 23 to resiliently urge the plate 21
to swing outwardly and bias the door 19 to its fully open
position.
A pair of opposite parallel longitudinal track defining channel
members 27 are secured to the confronting faces of side walls 14
and 16 proximate bottom wall 13 and longitudinally slideably
support a plate 28 for carrying a food bowl or other receptacle 29
the forward edge of slide plate 28 being curved. A bracket 30
having a horizontal ear is medially mounted on the lower inside
face of the door 19 and an elongated link 32 has one end pivoted to
the bracket ear and its other end pivoted to the rear medial
underface of slide plate 28, so that with the opening of door 19
slide plate 28 is withdrawn by link 32 to a forwardly projecting
position and with the closing of door 19, the link 32 retracts
slide plate 28 completely within the cabinet 11.
A horizontal partition 33 is located in cabinet 11 intermediate top
and bottom walls 12 and 13 and an upright mechanical spring wound
alarm clock 34 of conventional construction is supported by
partition 33 and is firmly embraced between partition 33 and top
wall 12 at the front medial portion of partition 33. The rear face
of clock 34 confronts side wall 16 and the clock 34 includes, in
the known manner, a pair of shafts 36 for winding the clock spring
motor and for setting the time and for setting the alarm time, the
shafts 36 having coaxial extensions 37 coupled thereto and
projecting through apertures in the wall 16 to permit the external
setting and winding of the clock. The clock 34 also includes a
spring wound alarm motor provided with a shaft 38 which rotates in
a first direction to wind the motor spring, and is rotated in an
opposite second direction with the unwinding of the alarm motor
spring which actuates and sounds the clock alarm at the preset
time.
A door locking assembly 39 is located between clock 34 and side
wall 16, and includes a tubular vertical post 40 mounted atop
partition 33 and having an upper coaxial section 41 of reduced
diameter. Resting on the horizontal peripheral shoulder delineating
the upper and lower sections of post 40 and rotatable in upper
section 41 is a bevel gear 42 with upwardly directed teeth. A
hollow shaft 43 coaxial with post 40 has a bore of the diameter of
and axially aligned with that in post 40 and terminates at its
bottom in a bevel gear 44 located above and confronting bevel gear
42 and being rotatable with shaft 43. The shaft 43 projects through
top wall 12 and terminates at its top in a horizontal first disc 46
having a circular hub 47 on its bottom face resting on top wall 12.
An upwardly directed pin 48 is eccentrically mounted on disc
46.
A latch member defining rod 49 having a rounded bottom tip
slideably engages the aligned bores in shaft 43 and post 40 and has
affixed to the top thereof a second disc 50 located above first
disc 46 and having formed at its top a coaxial knob 51 and at its
periphery, an outwardly directed finger 52. An upwardly projecting
pin 53 is located on top wall 12 in the path of finger 52.
An arcuately extending wedge shaped member 54 projects upwardly
from the peripheral border of the top face of disc 46 and has an
inclined top face 56 and an arcuate wedge shaped member or skirt
wall 57 depends from the periphery of disc 50 and has an inclined
underface 58 complementing wedge member face 56 so that when discs
46 and 50 are relatively rotated to bring faces 56 and 58 into
mating registry, the disc 50 and latch member 49 are released to
their depressed position, as shown in FIG. 2, and when the disc 46
is rotated clockwise, as viewed in FIG. 5, relative to the disc 50,
the members are relatively shifted to raise the disc 50 and latch
member 49. A bevel gear 59 is affixed to alarm motor shaft 38 and
engages gears 42 and 44, and with the unwinding of the alarm motor
the gear 59 rotates the gear 44 to turn the disc 46
counter-clockwise. The pin 53 limits the amount of rotation of disc
50 ao as to ensure relative rotation between disc 50 and motor
driven disc 46, and the pin 48 and finger 52 provide a drive
coupling between discs 46 and 50 during the manual clockwise
rotation of knob 51 for the winding of the alarm motor.
An arm 63 has one end pivoted to a bracket 64 mounted on the inside
face of door 19 and has a longitudinal slot 65 formed at its
opposite end. The arm 63 extends below the partition 33 and a guide
pin 66 mounted on a projection depending from partition 33
slideably engages the slot 66. A socket member 67 mounted atop the
arm 63 between its ends has a well 68 formed in its top face which
is in axial alignment with the latch rod 49 when the door 19 is in
its closed position with the arm 63 retracted thereby.
A closed water tank 70 is mounted in the upper part of cabinet 11
adjacent to side wall 14 and a freely moveable open topped circular
trough 71 is located externally of the cabinet, and is provided
with a depending pedestal 72 for supporting it on the floor. A
large vertical tubular member 73 is affixed to the inside face of
trough 71 with its bottom positioned between the top and bottom of
the trough. A long, flexible feed tube 74 which is smaller in
diameter than tube 73, has its upper end communicating with the
bottom of tank 70 by way of a suitable coupling, and has its lower
end communicating with the bottom of trough 71, likewise through a
suitable coupling, the tube 74 extending through an aperture in
side wall 14. A flexible venting tube 76 communicates through a
suitable coupling with the upper part of tank 70, and its lower end
is in hermetic engagement with tubular member 73.
A pair of vertically spaced elastomeric suction cups 77 are secured
to the outer face of side wall 16 for the separable attachment of
pet play devices.
In the operation and application of the device 10, tank 70 is first
filled with water by raising the trough 71 above the level of tank
70 and pouring water into trough 71 which flows through tube 74
into the tank. Water passes from the small connecting tube 74 down
near the base of the box and upwardly thence into the tank 70. This
is accomplished by gravity. When the tank is filled, dripping will
occur from the large tube 73 because of the overflow. The tank is
hermetically sealed. Thus, when the trough is placed at its lower
level, in the beginning water will come out both tubes into the
bowl, but then because of external air pressure, water will only
flow through the small tube 74, while air will pass through the
large tube 73 into the tank to replace the volume formerly filled
by water which has been vacated by the water dripping out. The tube
73 is positioned downwardly inside the water bowl, so that as the
water level reaches the mouth of the tube air will be further
prevented from passing upwardly in the tube. Water will pass
upwardly through the air tube to a certain level, but not all the
way up and into the tank only until a balance is reached. The
opening of the tube 73 at its lower end is of a much wider diameter
than the regular portion of the tube. When the dog drinks and
lowers the water level, the volume of water in the air tube 73
returns to the bowl, exposing the lower opening and allowing
external air pressure to enter the tube. Then air can pass upwardly
into the tube and force water to start entering into the bowl from
the tank via tube 74. The procedure is repeated until a balance is
reached again.
The reason for having an expanded diameter at the open portion of
the air tube 73 is the following: By having a section of tubing of
expanded diameter, the weight of the water in the air tube is
increased significantly. Thus, when the dog drinks the weight is
sufficient to drop rapidly back into the liquid bowl and allow the
process to start again. If we did not have this, according to the
inventor, and based upon his experiments, the system becomes
neutralized and the water stays up in the tube, retained in
position by the air pressure and gravity balance, the air pressure
being greater than the force created by the weight of the water in
the air tube, and the water will not come out of the air tube.
The clock 34 is wound and the alarm set to the desired food release
time and the clock alarm motor is wound through gears 59 and 44,
shaft 43 and discs 46 and 50 and pin 48 and finger 52 by turning
knob 51 clockwise until finger 52 reaches pin 53. With the door 19
open and plate 28 extended, a food containing bowl 29 placed on the
forward part of plate 28 and the door 19 is manually closed to
retract the plate 28 and bowl 29 into the cabinet 11. The knob 51
is then turned counter-clockwise until pin 53 is engaged by finger
52, in which position the cam and follower defining members 54 and
57 are out of engagement permitting the latch rod 49 to drop into
locking engagement with socket well 68 and retain the door in
closed position.
At the preset alarm time, the clock alarm is released to sound and
attract the animal, and with the unwinding of the alarm motor the
driven gear 59 rotates disc 46 by way of gear 44 to raise the disc
50 and latch member rod 49 from well 68, thereby releasing the door
which is swung to its open position withdrawing slide plate 28 and
the food containing bowl 29. The amount of unwinding of the alarm
motor and the sounding of the alarm is limited by the restricted
rotation of disc 46 to less than 360.degree..
As shown in FIGS. 9 to 11, a collapsible mat or shelter 78 may be
associated with the cabinet 11 and includes a plastic web 79
divided by longitudinally and transversely extending fold lines 80
into rows and lines of similarly shaped rectangular panels 81, in
the illustrated embodiment four rows of panels with four panels to
the row. The rear edge of a rear corner panel is provided with a
rearwardly projecting flap which is secured to the border of the
underface of bottom wall 13.
In the collapsed condition of the web 79, it is folded, accordion
fashion, longitudinally and transversely, as shown in FIG. 9 and
brought into superimposition with side wall 14. A U-shaped
resilient frame member 83 includes a top cross piece 84 and
depending opposite end legs 86, the legs 86 tightly embracing the
collapsed web along side wall 14 and opposite side wall 16.
In employing the web 79 as a mat, the frame 83 is removed to
release the web 79 which is open along the fold lines to its
desired size and configuration and permitted to rest upon the
floor. On the other hand, if the web 79 is to be used as a shelter,
it is unfolded to its full extent and then folded along transverse
fold lines to form a rectangular tunnel, as shown by broken line in
FIG. 10, and the frame member 83 is inserted in the tunnel,
extending longitudinally, to prevent the collapse of the
shelter.
A play device 87, which may be employed by way of example, with the
device 10 is illustrated in FIGS. 12 to 14 and includes a vertical
cylindrical clawing block 88 having a planar rear face to which is
secured a vertically extending flat coupling plate 89 having a
smooth rear face. A vertical pin 90 projects upwardly from the
block 88 and registers with the dihedral between the faces of block
88 and plate 89. A resilient flexible tubular arm 91 formed of a
helically wound wire has its inner end engaging the pin 90 and
projects forwardly of block 88. Suspended from the free end of arm
91 by means of a chain 92 is any suitable toy 85, such as a catnip
stuffed figure, or the like.
In use, the device 87 is supported at the desired level by
effecting a suction coupling between the suction cups 77 and the
plate 89 in the known manner. Other toys and playthings may be
substituted for the device 87 and attached to the cabinet 11 in a
similar manner.
While there have been described and illustrated preferred
embodiments of the present invention, it is apparent that numerous
alterations, omissions and additions may be made without departing
from the spirit thereof.
