Richard Karl Boog, Newark, N. J.
Application October 25, 1937, Serial No. 170,927
2 Claims.
My invention relates to improvements in clasps,
or clips, for securing the wings of collars to»
gether against displacement from curling and
other causes.
5
The primary object of the invention is the pro
vision of an inexpensive device of this character
which may be more quickly and easily applied
than the present day clasps of commerce and
which will securely hold the collar in desired
position without tearing or otherwise mutilating
the same.
Other, and subordinate objects, are also com
prehended by my invention, all of which together
d with the precise nature of my improvements
will be readily apparent when the following de
scription and claims are read with reference to
the drawing accompanying and forming part of
this specification.
Figure 1 is a view in front elevation of my im
proved clasps,
Figure 2 is a view in longitudinal section taken
on the line 2-2 of Figure l, and
Figure 3 is a View in rear elevation.
Referring to the drawing by numerals, in the
preferred embodiment of my invention illus
trated in the drawing, the clasp thereof com
prises a front jaw member I, of suitable light
metal, having the form of an elongated shell in
30 cluding an outwardly bowed front wall 2, in
wardly curved ends 3 and side walls 4. The side
walls 4 are provided on each side of the trans
verse center thereof adjacent to said center with
a pair of opposed ear-like extensions 5. The
' back of the clasp is formed by a pair of similar
shell-like jaw members 1 and 8, each comprising
a rear wall 9, a curved outer end I0 and side
walls II. The members 1 and 8 are disposed
end-to-end with the side Walls Il and ends I0
mating with the side walls 4 and ends 3 of the
member I in clamping relation thereto at op
posite ends of the member I respectively. The
pair of jaw members 1 and 8 are pivoted, as at
II', to the pairs of extensions 5, respectively,
' intermediate their ends for relative movement to
swing the same into and from clamping relation
to the member I. The adjacent ends of the jaw
members 1 and 8 are pivoted together by means
of a pair of elliptical or elongated eye members
I2 and I3 formed on said ends, respectively, and
a pivot pin I4 extended loosely through said eye
members and held against endwise movement by
the side walls II of one of said members. A pair
oi tension springs I5 are interposed between the
“ front walls 2 and the adjacent ends of the mem
(Cl. 24-81)
bers 1 and 8 upon opposite sides of the pivot pin
I4, respectively, and between said pin and the
pivots II', respectively, whereby the members 1
and 8 are tensioned against movement from
clamping relation to the member I. The mating Ul
side walls 4 and II and the ends 3 and I0 are
serrated, as at I6, to facilitate gripping the collar,
not shown, therebetween, the serrations being
rounded to obviate tearing of the collar. Suit
able keepers I1 on the member I and the mem 10
bers 1 and 8 anchor the springs I5 in location.
Preferably the keepers I1 take the form of a
pair of opposed yoke like members one secured
to the inner face of the jaw member I and the
other adapted to straddle the elliptical eye mem- l
bers I2 and I3 and ñt around the same against the
inner faces of the members 1 and 8, in detached
relation thereto, so as not to interfere with the
movement thereof.
As will be clear, by grasping the described
clasp between two fingers and thumb of one hand
with the fingers against the member I and the
thumb against either, or both, members 1 and 8,
intermediate the pivots II', and exerting the
required pressure on said members, the jaw mem
bers 1 and 8 may be swung simultaneously against
the tension of the springs I5 out of clamping
relation in the desired degree. The ears of the
collar may then be inserted between the members
I and 1 and 8 and pressure released whereupon
the members 1 and 8 will snap into clamping
relation to member I simultaneously.
The construction, operation and advantages of
my invention will, it is believed, be clear from
the foregoing without further explanation.
35
Manifestly the invention, as described, is sus
ceptible of modification without departing from
the inventive concept and right is herein reserved
to such modiñcations as fall within the scope of
the claims appended hereto.

What I claim is:
1. A clasp for collars comprising a front jaw
member, a pair of rear jaw members pivotally
mounted intermediate their ends on the front
_
jaw member in end-to-end position for relative
swinging movement into and from clamping rela
tion with respect to the opposite ends of the front
member, respectively, a pivotal sliding connec
tion between adjacent ends of said pair of mem
bers compensating for relative swinging move
ment thereof and connecting said members to
gether, said connection comprising a pair of
elongated eye members on said ends, respectively,
and a pin extending through said eye members, 55

and means tensioning said pair of members
elongated eye members on said ends, respectively,
against movement from clamping relation.
2. A clasp for collars comprising a front jaw
member, a pair of rear jaw members pivotally
and a pin extending through said eye members,
and means tensioning said pair of members
against movement from clamping relation and
comprising a pair of opposed yokes one ñxed to 5
the front jaw member opposite said eye members
to extend upon opposite sides of the latter, and
the other spanning said eye members and slid
ably engaging the same and the adjacent ends
of said pair of jaw members, and a pair of ten
sion springs interposed between opposed ends of
the said yokes.
