Description
STATEMENT OF INVENTION
This invention relates to paint bucket supports and, more
particularly, to paint bucket supports and ladder attachments.
OBJECTS OF THE INVENTION
It is an object of the invention to provide an improved ladder
attachment and tool holder.
Another object of the invention is to provide a paint bucket holder
and ladder attachment which is simple in construction, economical
to manufacture, and simple and efficient to use.
Another object of the invention is to provide an improved attaching
means to be used with an aluminum extension ladder.
Another object of the invention is to provide an improved and
versatile platform for working from ladders.
Another object of the invention is to provide an improved paint
bucket holder and ladder attachment which is small in size and
sturdy in construction and reliable to use.
With the above and other objects in view, the present invention
consists of the combination and arrangement of parts hereinafter
more fully described, illustrated in the accompanying drawings and
more particularly pointed out in the appended claims, it being
understood that changes may be made in the form, size, proportions,
and minor details of construction without departing from the spirit
or sacrificing any of the advantages of the invention.

1.
DETAILED DESCRIPTION OF THE DRAWINGS
Now with more particular reference to the drawings, a paint bucket
support and ladder attachment shown generally at 10 has a platform
11 which has a flat top surface and a support member 12 fixed to
the underside of the platform 11. The edges of the platform 11 are
turned down on three sides to form flanges 32, 33 and 34 which are
joined by welding or the like at intersecting edges 36 and 37. The
flat surface of the platform 11 has a slot or an elongated hole 20
extending through it. The slot 20 is suitable for holding a putty
knife, or other similar tools, and spaced tool receiving holes 21,
22 and 23 are suitable for receiving screwdrivers, pliers, and othe
small tools. The holes 47 and 48 in the turned down end flange 33
of the platform 11 may accommodate a hook suitable for holding a
paint brush. The top surface of the platform 11 has several sets of
spaced small holes 24, 25 and 26 to receive the paint bucket clips
27, 28, 29 and 30. The different sets of holes 24, 25 and 26 allow
the adjustment of the clips 27, 28, 29 and 30 toward the center of
the support to accommodate different sizes of paint buckets. The
paint bucket clips 27, 28, 29 and 30 are generally L-shaped with a
vertical portion 38 and a horizontal portion 39. These clips may be
made of steel or other suitable relatively rigid material. The
vertical portion of the clips are suitably curved at their upper
end 40 to guide a paint bucket into place and, therefore, make the
device efficient to use. The horizontal portion 39 of each paint
bucket clip 27, 28, 29 and 30 has a threaded portion 41 which
projects through the sets of holes 24, 25 and 26 and to which the
wing nuts 31 may be tightened to hold the paint bucket clips in
place.
The support member 12 is generally channel shaped in cross section
and is attached to the bottom of the support member by spot welding
or other fastening means. The support member is generally U-shaped
in cross section and has vertical sides 42 and 43 connected by the
horizontal top 44. Sides 42 and 43 narrow at the point 13 where the
support member porjects beyond the platform 11. This is to permit
the entry of support member 12 into the hollow rung 45 of an
aluminum ladder 46. To hold the support member 12 in place, a knob
16 is provided which threadably engages the end of the connecting
rod 14 on threads 35. The connecting rod 14 passes through a hole
49 in the flange 33 and through a hole 50 in the guide block 17.
The guide block 17 is held by support 18 between the flanges of the
support member 12 so that the connecting rod 14 freely slides in
the hole 50. The angle block 19 has an inclined surface 52 which is
inclined toward the distal end of the support member. The ladder
engaging block 15 has an inclined upper surface 51 which engages
the inclined surface 52 on the angle block 19 so that when the knob
16 is turned on threaded end 35, the connecting rod 14 draws the
block 15 with inclined surface 51 along the inclined surface 52 and
causes the block 15 to move outward from the channel in the support
member 12 thereby engaging the hollow bore in a ladder rung 45 and
clamping the support member in position.
To use the device shown, the knurled knob 16 is first loosened on
the threads 35 so that the ladder engaging block 15 may slide along
the inclined surface 52 of the angle block 19 to its position below
the flanges of the support member 12. The support member 12 is then
inserted in a hollow in the aluminum ladder rung 45 and the knob 16
tightened to draw the block 15 toward the guide block 17. This
causes it to ride up on the inclined surface 52 of the block 19 and
move outward from the channel of the support member 12 thereby
engaging the inside of the ladder rung 45 holding the support
member 12 in position.
The foregoing specification sets forth the invention in its
preferred practical forms but the structure shown is capable of
modification within a range of equivalents without departing from
the invention which is to be understood is broadly novel as is
commensurate with the appended claims.
