Year: 1895

page_text: Date of Application, 12th Jan., 1895
Complete Specification Left, 8th Oct., 1895-Accepted, 9th Nov., 1895
We, HOPE STREET FACTORY LIMITED, of Belfast, in the County of Antrim,
Manufacturers, and JOHN LAIRD of No. 4 Hibernia Place, Lisburn Road, Belfast
aforesaid, Engineer, in the employ of the said Company do hereby declare the
nature of this invention to be as follows:-
Our invention refers to cloth clamps for holding several layers of cloth or other
fabric together during the operations of cutting out.
The clamp consists of two jaws which are pivotted together and provided with a
screw one end of which is secured to one of the jaws (preferably the lower one)
while the other end goes through a slot in the other jaw and is provided with a nut
on to which is pivotted a cam lever so that when the layers of stuff are inserted
between the jaws the nut is easily screwed down to somewhere near the upper jaw
of the clamp and the clamping is then effected by actuating the cam lever which
presses on the upper jaw aud brings it closer to the lower one. The clamp may
conveniently be provided with a spring to cause the jaws to remain normally open
and ready for the insertion of the fabric.

Improvements in Cloth Clamps.
We, HOPE STREET FACTORY LIMITED, of Belfast, in the County of Antrim,
Manufacturers, and JOHN LAIRD of No. 4 Hibernia Place, Lisburn Road, Belfast
aforesaid, Engineer in the employ of the said Company, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
Our invention refers to cloth clamps for holding several layers of cloth or other
fabric together during the operations of cutting out.
Fig. 1 of the accompanying sheet of drawings represents in elevation a cloth
clamp, constructed according to this invention ready for the insertion of the cloth.
Fig. 2 is a plan thereof.
Fig. 3 shows in elevation the cloth clamp clamping several layers of cloth and
Figs. 4 and 5 are views in elevation of modifications on a smaller scale.
The clamp consists of 2 jaws A and B which are pivotted together at C in any
convenient manner and provided with a screw or bolt D one end of which is rivettel
or otherwise secured to one of the jaws (preferably the lower one B) while the
other end goes through a slot a¹ in the jaw A. The screw D is provided with a
mut E on to which is pivotted at F a cam lever G so that when the layers of stuff H
(shown only in Fig. 3) are inserted between the jaws A. and B, the nut is easily
screwed down to somewhere near the upper jaw A of the clamp and the final
pressure for the clamping is then effected by actuating the cam lever G which is

page_text: revolved from its position shown in Fig. 1 to that shown in Fig. 3 and presses on
the upper jaw and brings it closer to the lower one. The clamp may conveniently
be provided with a spring I rivetted or otherwise attached to one of the jaws
to cause the latter to normally remain open and ready for the insertion of the
fabric.
The cam lever G may conveniently be provided with a pin or stop K to limit its
motion but this is not essential.
The jaws may if desired be made in one piece A for instance either U-shaped as
shown in Figure 4 or V-shaped as shown in Figure 5 and by this means the spring I
and the pivot C can be dispensed with.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. A cloth clamp consisting of two jaws normally held apart by a spring, a screw
fixed to one of the jaws and going through a slot in the other jaw, a nut on said
screw, and a cam lever pivotted to said nut substantially as set forth.
2. A cloth clamp consisting of two jaws A and B pivotted together at C and
normally held apart by a spring I, a screw D fixed to the jaws B and going through
a slot a in the jaw A, a nut E on said screw, and a cam lever G pivotted to said
nut substantially as described and shown.
3. A cloth clamp consisting of two jaws A made in one piece, a screw D fixed to
one of the jaws and going through a slot in the other jaw, a nut E on said screw
and a cam lever G pivotted to said nut substantially as described and shown.
