5 Claims. (Cl. 29-203)
FIG. 7 is a vertical longitudinal sectional view of the
device taken on line 7—7 of FIG. 5;
FIG. 8 is a vertical cross-sectional view of the device
taken on line 8—8 of FIG. 5; and
FIG. 9 is a fragmentary horizontal sectional view
through the device set up to act on armature components
having short armatures.
Referring to the drawings, the present device is de
signed to strip defective U-shaped hinge springs 15
This invention relates to a device ‘for stripping a thin 10 (FIGS. 2 and 3) from U-shaped armatures 16 of arma
part from the side of an article to which it is attached,
ture components used in wire spring relays. The U
and more particularly to a device for removing a defec
shaped hinge springs 15 are made from thin ?at spring
tive hinge spring from an armature to which a portion of
the spring is wrapped around and spot welded.
In one type of wire spring relay, a U—shaped armature
is supported for pivotal movement by a ?at U-sha-ped
hinge spring which has enlarged end portions wrapped
around the ends of the U-shaped armature and spot
steel .005” in thickness and have enlarged end portions
18 on the ‘legs thereof which are placed in overlapping
relation to the ends of the armature legs, wrapped there
around, and spot welded thereto at 19 to secure ?xedly
the ‘hinge springs 15 to the armatures 16. As shown in
FIGS. 2 and 3, the armatures 16 are of two sizes, the
welded thereto. During the operation of attaching the
legs of the long armature (FIG. 2) being of greater
springs to the MHIQILII‘ES or during subsequent operations 20 length-than those of the ‘short armature (FIG. 3). As
such as bending the springs, the springs may become
clearly shown in FIG. 4, the portions 18 of the spring
damaged and the armature components rendered de
fective. It has been found to be economically desirable
to remove the :hinge springs from the armature in order
that the armatures may be reused.
An object of the present invention is to provide a de
vice for stripping a thin part from the side of an article
.to which the part is attached.
Another object of the invention is to provide a device
15 which overlap the end portions of the armatures 16
are disposed on opposite sides of the ends of the armature
legs and form shoulders projecting laterally from op
posite sides thereof.
The device for stripping the spring 15 from the arma
ture 16 comprises a holder 25 in the form of a hori
zontally disposed block of rectangular cross section which
is ?xedly mounted to a vertically disposed frame plate 26
for removing a defective ?at hinge spring from a relay
mounted on a suitable support such as a bench or work
armature around a portion of which armature a portion
table. The holder 25, which has a predetermined height
or thickness substantially equal to the distance between
of the spring is wrapped and welded.
A further object of the invention is to provide a novel
device for moving a pair of stripping jaws into engage
ment with opposite sides of a flat article and maintaining
the jaws in engagement therewith while the article is
being held and the jaws are being moved longitudinally
of the article to strip therefrom a part that is secured to
v the sides of the article.
With these and other objects in view, the invention
contemplates the provision of a slotted holder for receiv
ing a ?at article, a latch for locking the article therein
and a tubular carrier telescoped over the holder for
supporting a pair of pivoted stripping jaws for longitudi
nal movement therewith parallel to and on opposite sides
‘of the article. A pair of cam members ?oatingly
mounted between the holder and the carrier and between
and in engagement with the jaws and the side walls of the
tubular carrier have sloping surfaces for moving the
jaws into engagement with the sides of the article and for
maintaining this engagement as the jaws are advanced
‘ longitudinally with the carrier by power-driven actuating
means to effect the stripping from the article of a thin
part that is secured to opposite sides thereof.
the legs of the armatures 16, has a slot 27 ‘formed in one
end thereof for receiving the armatures 16 therein. The
end 28 of'the slot 27 forms ‘a stop engageable with the
end 29 of the long armature 16 for locating the over
lapping portion 18 of the spring 15 in a predetermined
position longitudinally of the holder.
A latching bar 32 which is slidably mounted in a slot
33 in the holder 25 is movable from ‘a normal unopera
tive position (FIG. 5) to an operative position (FIG. 6)
for ?tting between the legs of the armature 16 and engag
ing the cross head 34 thereof to locate the armature ver
tically in a predetermined position and to lock it in ?xed
position relative to the holder with the overlapping end
portions 18 of the hinge spring 15 in a predetermined
stripping position. A rod 36 extends from the latching
bar 32 and has an upwardly directed end 37 ?tting in a
recess 38' in an actuating lever 39 pivotally supported at
40 on the stationary frame plate 26. The end 37 of the
rod 36 is locked to the operating lever 38 by a latch 44
which is secured to a pin 45 oscillatably' mounted on the
lever 39.
When the hinge springs '15 are to be removed from

Telescopingly mounted on the stationary holder 25
for longitudinal sliding movement relative thereto is a

1 to advance the latching bar 32 into operative position
to lock the armature 16 in position on the holder 25
with the legs of the armature disposed between the strip
cross section open at one end to permit the insertion of 10 ping jaws ‘69 and with the overlapping portions 18 of the
the armatures 16 into the holder 25. The carrier 60 in
spring 115 disposed in advance of and in close proximity
cludes upper and lower walls 61 and 62, respectively,
to the ends 70 of the stripping jaws. The actuation of
the lever 39 also trips the valve 104 to admit compressed

vertically disposed ?anged portions 81 on one end of the
holder 25 urge the cam members 77 in a direction to
impart movement to the stripping jaws 69 toward each
