PROVISIONAL SPECIFICATION.
Improvements in Brake Connections for Power Looms.
THOMAS SINGLETON Bank Top Works Darwen in the County of Lancaster,
Machinist do hereby declare the nature of this invention to be as follows:-
The object novelty and utility of this invention are to facilitate and exact the
brake power of a loom.
Now in order to accomplish the object of this my invention I proceed as
follows-
Instead of the plain inclined lever fulcrum to the clow at the shuttle rest end
of the breast beam, commonly called horsehead, I connect a suitable shaped
slotted inclined lever or equivalent. On the ordinary connecting rod, that
connects the inclined lever and the brake lever I place an open spiral spring
with a fast and loose boss, the top boss is secured to the rod for regulating
purposes, the loose one resting upon the brake lever and actuates the brake
power, instead of a dead weight, and prevents the rebounding of the lever.
Instead of the ordinary bonnet secured to the ordinary spring handle I secure
a suitable shaped stud or equivalent to work the aforesaid slotted lever.
Instead of the ordinary tumbler for holding the brake lever secured to the
spring handle, I connect or secure a suitable shaped drop catch or equivalent.
Dated this 4th day of August 1892.

COMPLETE SPECIFICATION.
Improvements in Brake Connections for Power Looms.
I, THOMAS SINGLETON of Bank Top Works, Darwen, in the County of Lancaster,
Machinist, 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 for operating and con-
trolling the brake of looms for weaving, the object being to facilitate the
application to, and withdrawal of the brake from the brake wheel when requisite.
According to this invention pressure is applied to the brake lever by means
of a spiral spring compressed and controlled by a slotted inclined lever raised or
lowered by a pin or stud fast to the ordinary spring handle.
For holding the brake off the brake wheel I employ a drop catch which can
be operated by foot or hand by the attendant on the loom.
By use of the said improved appliances the ordinary dead weights for weighting
the brake lever are dispensed with and the objectionable rebounding of said
lever is thereby obviated.
Such being the nature and object of the said invention the following is a
complete description of same reference being made to the accompanying drawings
forming a part of this Specification in which :-
Fig. is a front elevation of the improved appliances shewn applied to the
brake lever of a loom.
Fig. 2 is an end elevation of Fig. 1.
Fig. 3 is a detail of the drop catch for holding the brake lever.
According to this invention in lieu of the ordinary inclined lever commonly
called "horsehead" heretofore employed I mount loosely on the bracket 1 fixed
to the underside of the shuttle rest 2 at the end of the loom are inclined slutted

page_text: lever 3. The end of the slotted lever 3 is by the ordinary connecting rod 4
connected to near the end of the brake lever 5, and on the connecting rod 4 I
place an open spiral spring 6 above which is the adjustable fixed boss 7 for
regulating the pressure of the spring 6. Below the spring 6, and loose on the
connecting rod 4 is a boss 8 which rests on the top side of the brake lever 5
and on the rod 4 which passes loosely through a hole in the brake lever 5 and
below said brake lever 5' is the fixed boss 8ª.
Fixed to the ordinary stop or spring handle 9 is a pin or stud 10 which is
received in the slot in the slotted lever 3.
Below the brake lever 5 and free to move on a fulcrum stud 11 fixed to the
end frame 12 of the loom is the drop catch 13 which when in the position
shewn by Fig. 2 allows free play to the brake lever 5, but if it is desired to
remove the brake from the brake wheel 14 (in whatever position the different
appliances connected therewith may be) the operative will by hand or foot press
on the end 15 of the drop catch 13 turning the latter on its fulcrum stud 11
and so bringing the part 16 of the drop catch to bear against the underside of
the brake lever 5 as shewn by Fig. 3 and this will slightly raise the end of the
brake lever 5, compress the spiral spring 6 and the brake 17 will be held clear
of the brake wheel 14 until the drop catch 13 is moved by the operative to the
position shewn by Fig. 2.
When the loom is to be stopped by the spring handle 9 being "knocked" or
moved off the handle carries the pin or stud 10 to the higher end of the slot in the
slotted lever 3 and the slotted lever 3 is forced downwards and by the fixed boss 7
the spiral spring 6 is compressed and bears on the boss 8 and on the end of the
brake lever 5 and by the latter turning on its fulcrum stud 18 the brake 17 is applied
to the brake wheel 14 and the motion of the loom is quickly arrested without any
rebound or jar.
When the stop or spring handle 9 is moved to restart the loom the pin or stud 10
travels to the lower end of the slot in the slotted lever 3 and raises the spiral spring,
and the connecting rod 4 and by the fixed boss 8 the end of the brake lever 5 is
raised and the brake removed from the brake wheel.
It will be seen that in stopping or restarting the loom little or no weight has to
be raised by the handle 9.
Having now particularly described and ascertained the nature and object of the
said invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The general construction, arrangement and combination of parts for operating
and controlling the brake of looms for weaving as herein fully described and as
illustrated by the annexed drawings.
2. The inclined clotted lever 3 pin or stud 10 connection 4 spiral spring 6
bosses 88 and brake lever 5 all in combination, and with (or without) the drop
catch 13 and as and for the purpose herein described and as illustrated by the
annexed drawings.
Dated the 4th day of May 1893.
