Description
HISTORICAL BACKGROUND
In the past, reed switches have been made primarily to perform a
single switching function or in some instances a flip-flop
function. Where a reed switch has been biased (by placing the
switch in a polarized field for subsequent neutralization by a
second field of opposite polarity), the polarization in any
instance has not been a permanent one associated with the reed
itself. For the most part, polarization has been brought about by
induction and the like. Further, there has been little or no
attempt to provide reed switches which have a many-function aspect
and which permit a plurality of switching operations in addition to
the usual flip-flop arrangement. Furthermore, there has been no
attempt to structurally design the reed switches for easier connect
and disconnect by "branching" or the like. In this regard, this
invention is particularly adaptable for use in systems such as
described in my copending application Ser. No. 669,614 filed Sept.
21, 1967, now U.S. Pat. No. 3,447,105 issued July 27, 1969, and my
U.S. Pat. No. 3,261,941 issued July 19, 1966.
OBJECTS AND SUMMARY
It is therefore an object of this invention to provide a reed
switch which allows for a plurality of switching operations.
A further object of this invention is to provide a reed switch
which has a plurality of branches or arms radiating in various
directions to permit ease in installation and to allow flexibility
for use in diverse control mechanisms.
Another object of this invention is to provide a reed switch a
portion of which is polarized and a portion of which is unpolarized
to allow for various switching operations when an oppositely
polarized field is brought into proximity thereto.
Still another object of this invention is to provide a reed switch
which is simple and economical to manufacture.
A further object of this invention is to provide a reed switch
which is in capsule form and which has its contacts sealed to
prevent unnecessary corrosion and arcing.
Still a further object of this invention is to provide a reed
switch in which the contacts may be placed in an inert atmosphere
or the like.
Yet another object of this invention is to provide a reed switch
which may be biased in more than one direction by a plurality of
permanent magnets permanently fixed to the switch.
Another object of this invention is to provide a reed switch having
a plurality of operating contacts in close proximity to each other
for producing a multiplicity of switching operations at high speed
due to the close proximity thereof.
These and other objects of this invention will be apparent the
following description and claims.
In the accompanying drawings which illustrate by way of example
various embodiments of this invention:
FIG. 1 is an enlarged plan view of the invention;
FIG. 1A is a sectional view taken along the lines of 1A-1A in FIG.
1 and viewed in the direction of the arrow;
FIGS. 2, 3, and 4 are plan views of the invention illustrated in
FIG. 1 and showing three different stages of operation as caused by
fields of opposite polarity;
FIGS. 5 through 10, 11 and 12 are enlarged plan views showing
various other embodiments of the invention with portions shown in
dash lines to illustrate various positions of the switch reeds;
FIG. 10A is a cross-sectional view taken along the lines of 10A-10A
of FIG. 10 and viewed in the direction of the arrows;
FIG. 13 is an enlarged fragmentary cross-sectional view
illustrating another embodiment of the invention in which the reed
is encircled by a washer-type permanent magnet having the poles
running in a vertical direction.
FIGS. 1 THROUGH 4
In FIGS. 1 through 4, the capsule C forms the housing for the reeds
2, 4 and 6. The capsule C may be of glass or other encapsulating
material such as plastic, etc. The reeds 2, 4, and 6 are sealed
respectively in the radial arms or legs of the capsule. In the case
of glass, the tubing is sealed both at the ends of the legs 8, 10
and 12 forming sealing beads of glass 14, 16, and 18. The reed 2
extends into the leg 8 to a point approximately midway of the
capsule. Abutting the reed 2 on either side and normally in contact
therewith are the reeds 4 and 6. The reeds 4 and 6 may have contact
feet 20 and 22 as illustrated. The reeds 2, 4 and 6 will be made of
a material which has a magnetic characteristic. For good
conductivity, the reeds may be coated with a conductor material
such as gold, silver, etc.
Affixed to a reed 2 in a permanent way is a permanent magnet 24.
The magnet 24 may be welded, threaded, cemented, wedged, or
otherwise secured to the reed 2 so that is will not be readily
removable. It is contemplated that for some purposes the magnet 24
might be removable but preferably force would be required in order
to remove the same such as unthreading, etc. As illustrated, the
permanent magnet 24 is welded or otherwise secured to the reed
2.
OPERATION
In operation, the reeds 4 and 6 normally are in contact with the
reed 2 as illustrated in FIG. 1. When a magnet 26 having a polarity
opposite to the polarity of the magnet 24 is passed in the vicinity
of the reed 4, it has been found that the reed 4 will back away
from reed 2 in the manner illustrated in FIG. 2 leaving only the
single contact between the reed 6 and the reed 2. The approach of
the magnet 26 at one leg as illustrated in FIG. 2 will not have an
effect on the other leg to bias the reed 6 away from the reed
2.
When the magnet 26 is shifted, as illustrated in FIG. 3, to the
proximity of the reed 6, and an additional magnet 28 is moved into
the proximity of the reed 4, and when the polarities of the magnets
28 and 26 are opposite to the magnet 24, the reeds 4 and 6 will
move away from the reed 2 in the manner illustrated thereby
breaking all contact with the reed 2.
When as illustrated in FIG. 4, the magnet 28 is shifted from the
vicinity of the reed 4 to the vicinity of the reed 6, the reed 4
will again close and make contact with the reed 2. The magnet 28
will maintain the reed 6 from out of contact engagement with the
reed 2 as illustrated in FIG. 4.
FIG. 5
In FIG. 5, the reeds 30, 32 and 34 are sealed in the legs 36, 38
and 40 of the capsule. The reed 34 is movable between the reeds 30
and 32 from the full-line position to the dashline position as
illustrated. Reed 30 is polarized by means of a magnet 42 which is
affixed in a permanent manner to the reed 30.
OPERATION
When the magnet 44 of opposite polarity to the magnet 42 is placed
in the vicinity of the reed 34, the opposite polarities will cause
the reed 34 to move from contact engagement with the reed 30 into
contact engagement with the reed 32. Upon removal of the magnet 44,
the reed 34 will again return to its position in contact with the
reed 30. If it is desired that the reed 34 remain in contact with
the reed 32, a second magnet 46 can be affixed to the reed 32. The
magnet 46 must have a polarity similar to the polarity of the
magnet 42. Thus, when the magnet 44 is moved into the vicinity of
the reed 34, it will be of opposite polarity to the reed 42 but of
the same polarity with the reed 46 and thus the reed 34 will switch
from permanent contact with the reed 30 to permanent contact with
the reed 32. A reversal of the direction of the magnet 44 will
shift the reed 34 back to its original contact with the reed
30.
FIGS. 6, 7 AND 8
In FIG. 6, the reed 48 which is mounted in the capsule is provided
with a contact surface 50. Reeds 52 and 54 rest on the contact
surface 50. A permanent magnet 56 is secured to the reed 48. It
will be noted that the reeds 52 and 54 may be mounted either above
the contact surface 50 as shown in FIG. 6, or below the contact
surface (not shown).
OPERATION
It will now be obvious that when the magnets 58 and 60 having
polarities opposite to the magnet 56 are brought either
simultaneously or individually into association with the reeds 52
and 54, the reeds 52 and 54 will raise from the contact surface 50
making contact with either or both sides of the contact surface 50
depending upon the positioning of the magnets 58 and 60. It will be
noted that the capsule C in both FIGS. 5 and 6 is T-shaped.
In FIG. 7, it will be noted that in addition to the arms or legs
62, 64 and 66, there is an additional leg 68 thus forming cruciform
shape. The leg 68 of the capsule encloses and seals a reed 70
having a contact surface 72.
OPERATION
It will now be obvious that in operation of FIG. 7, when the
magnets 74 and 76 are positioned either simultaneously or
individually in the vicinity of the reeds 52 and 54 respectively,
and when their polarities differ from the polarities of the magnet
56, there will be a shifting of the reeds 52 and 54 from contact
with the contact surface 50 to contact with the contact surface 72
of the reed 70.
As in the case of FIG. 5, if a second magnet 78 shown in dash lines
is affixed to the reed 70, the contact shift of the reeds 52 and 54
from the contact surface 50 to the contact 72 will be permanent
until the polarities of the magnets 74 and 76 are made opposite to
the magnet 78. It will be obvious that the polarities of the
magnets 56 and 78 will be the same.
In FIG. 8, the capsule C in addition to including the reeds 48, 52,
54 and 70, will also include the reeds 80, 82, 84 and 86. Reeds 80
and 84 will be in contact with the upper surface of the contact
surface 50 and reeds 82 and 86 will be in contact with the lower
surface of the contact surface 72.
OPERATION
The operation of the switch shown on FIG. 8 is similar to that of
FIG. 7 with the exception that when the magnets 74 and 76 either
individually or combined move into the vicinity of reeds 80, 82, 84
and 86, these reeds will shift from their respective contact
surfaces and thus break the circuit connection.
It will be obvious that various other contact arrangements can be
produced in multiple sequence utilizing in essence the various
principles heretofore illustrated and it will be further obvious
that the inclusion of the magnet 78 will affect the operation in a
manner similar to the operation illustrated in FIG. 7.
FIGS. 9 THROUGH 11
FIG. 9 illustrates yet another embodiment of the invention in which
three reeds 88, 90 and 92 are positioned above a pair of reeds 94
and 96 in the manner illustrated. Reeds 88 and 92 are provided with
permanent magnets 98 and 100 which are polarized in the same
direction. It will now be obvious that reeds 94 and 96 will
normally be in contact with the reeds 88 and 92. If magnets 102 and
104 are simultaneously or individually positioned in close
association with the reeds 94 and 96, and the polarities of the
magnets 102 and 104 are opposite to the polarities of the magnets
98 and 100, the reeds 94 and 96 will shift from contact with the
reeds 88 and 92 to contact with the reed 90 as illustrated in the
dash lines. If a magnet 106 is secured to the reed 90, and its
polarity is reverse of the polarity of the magnets 98 and 100, the
reeds 94 and 96 will remain in contact with the reed 90 until the
polarity of the magnets 102 and 104 is reversed.
In FIGS. 10 and 11, the reeds 108, 110, 112 and 114 are encapsuled
in the capsule. Reeds 108 and 110 are provided with magnets 116 and
118. The magnets are opposite in polarity. In FIG. 10, the reeds
112 and 114 are placed on the inside and in contact with the reeds
108 and 110 whereas in FIG. 11, the reeds 112 and 114 are placed in
contact with and outside of the reeds 108 and 110.
OPERATION
In operation, the magnet 120 is moved to a position so that its
poles are aligned so that a pole of the magnet 120 is opposing a
similar pole of the magnet 116 and the opposite pole of the magnet
120 is opposed to the similar pole of the magnet 118, the two reeds
112 and 114 will be forced away from in contact with the reeds 108
and 110 and into contact with each other as shown in the dash lines
in FIG. 10.
In FIG. 11, upon positioning of the magnet 126, the reeds 112 and
114 will be thrown outwardly and out of contact with each other and
with the reeds 108 and 110.
In the dotted lines in FIG. 11, additional reeds 122 and 124 may be
provided so as to operate in the manner illustrated in FIG. 10;
i.e., to contact each other when the magnet 120 is positioned in
the manner illustrated.
FIG. 12
FIG. 12 presents a further modification of the invention in which
reeds 126, 128 and 130 are positioned in contact with a Y-shaped
reed member 132 having reeds 134 and 136 forming the arms of the
Y-member 132. Reeds 126 and 130 are provided with magnets 138 and
140 which are oppositely polarized. The reed 128 is not
polarized.
OPERATION
In operation, the reeds 134 and 136 of the Y-shaped reed 132 are in
contact respectively with the reeds 126 and 128. When a magnet 142
is positioned in association with the reed member 132, as
illustrated in FIG. 12, and the polarity of the magnet 142 is
opposite to that of the magnet 132, the reeds 134 and 136 will
shift from contact with reeds 126 and 128 to contact with the reeds
128 and 130 respectively as illustrated.
As illustrated in dash lines, additional reeds 144 and 146 may be
provided in order to provide additional switching systems for the
overall capsule switch assembly. In this instance, the reeds 144
and 146 will normally be in contact with the reeds 126 and 130 when
the magnet 142 is not in position. When the magnet 142 is
positioned beneath and in close association with the reeds 144 and
146, and the polarity is the reverse of the polarity of the magnets
138 and 140 respectively, then the reeds 144 and 146 will move out
of contact engagement with the reeds 126 and 130.
FIG. 13
FIG. 13 shows the fragment of a capsule with a reed 148 positioned
therein. Associated with the reed 148 and connected thereto is a
ring magnet 150. The ring magnet is secured to the reed 148 and is
positioned thereon in the manner of a washer on a bolt. The ring
magnet is polarized so that the poles are axially aligned with the
axis of the reed 148. This is an alternate form for the various
magnets illustrated in the other drawings which are secured to one
side of the reed.
While the invention has been described in connection with different
embodiments thereof, it will be understood that it is capable of
further modification, and this application is intended to cover any
variations, uses, or adaptations of the invention following, in
general, the principles of the invention and including such
departures from the present disclosure as come within known or
customary practice in the art to which the invention pertains, and
as may be applied to the essential features hereinbefore set forth
and fall within the scope of the invention or the limits of the
appended claims.
