We ELI SHAW of 69 Cherry Street Blackburn in the County of Lancaster
Insurance Agent, and JAMES RILEY of 115 Mosley Street, Blackburn, aforesaid,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in appliances connected with the strap
fork and strap fork lever in looms for weaving the object being to maintain the
lever and fork in the correct position and to prevent their vibrating and working
loose on the carrying stud or pin of the fork lever.
According to this invention the fork lever is carried on a stud or pin as ordinary,
but the upper end of the stud or pin is elongated and serves to carry a strong blade
spring of bridge shape the centre of the spring being carried on the pin or stud
and each end of said spring rests on the lever of the strap fork. Locking nuts are
employed to screw on the pin or stud so that the required pressure can be applied
to the spring and thus prevent the lever vibrating and working loose.

COMPLETE SPECIFICATION.
Improvements in Appliances connected with the Strap Fork Levers
of Looms for Weaving.
We ELI SHAW of 69 Cherry Street Blackburn in the County of Lancaster
Insurance Agent and JAMES RILEY of 115 Mosley Street, Blackburn, aforesaid
Mill Manager, 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:-
This invention relates to improvements in appliances connected with the strap
fork and strap fork lever in looms for weaving, the object being to maintain the
lever and fork steadily in the correct position and to prevent their vibrating and
working loose on the carrying stud or pin of the fork lever.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings in
which :-
Fig. 1 is a side elevation of part of a strap fork, or strap fork lever, having our
improvements applied thereto.
According to this invention the fork lever 1 is carried on a stud or pin 2 as
ordinary, but the upper end of the stud or pin 2 is elongated and chased as at 3
and serves to carry a strong blade spring 4 of bridge shape the centre of the
spring 4 being carried on the pin or stud 2 and each end of said spring rests on the
lever 1 of the strap fork. A locking nut 5 or nuts are employed to screw on
the pin or stud 2 so that the required pressure can be applied to the spring 4 and
thus prevent the lever 1 vibrating and working loose.
At 6 is the bracket for carrying the fork lever i and this bracket is bolted to
the loom frame. The stud or pin 2 has a collar 7 formed on its said collar resting
on the top of the bracket 6, and the fork lever 1 rests on the top of the collar 7.

page_text: The spring 4 steadies the fork lever 1 and fork and prevents it vibrating
consequently the stud or pins last longer, and by keeping the fork steady an
advantage is gained both in starting and stopping the loom and "cracks
broken patterns are obviated.
and
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 :-
The fork lever 1 stud 2 and spring 4 all in combination as and for the purpose
.herein described and substantially as illustrated by the annexed drawings.
