Complete Specification Accepted, 17th Aug., 1888
I, JOSEPH TURNER of 32 Wellington Street, Mill Hill, Blackburn in the County of
Lancaster Mechanic, do hereby declare the nature of this invention to be as
follows:-
Heretofore the brakes of looms have been applied to the brake wheel directly
underneath the shaft of the brake wheel and at one place only and consequently when
the brake was applied great strain was put on the top of the shaft of the brake and on
the bush of the loom.
According to this my invention I employ a brake lever as ordinary on one end of
which is a wedge shaped brake shoe of wood, leather, or other suitable material.
Behind the brake wheel and underneath the shaft thereof is a horizontal bar supported
and free to move to and fro in brackets bolted to the side frame of the loom. On this
horizontal bar at each side of the brake wheel is a piece of wood or other material one
piece of which acts as a brake shoe on the brake wheel and the other acts as a fulcrum
for the wedge shaped brake shoe on the brake lever above mentioned.
The action is as follows:-When the brake is to be applied the handle of the brake
lever is pressed down thus raising the wedge shaped shoe on the opposite end of the
lever which presses against the brake wheel and at the same time the other side of the
wedge shaped shoe acts on one piece of wood on the horizontal bar sliding the same
in its bearing and thus brings the other piece of wood on the other end of the
horizontal bar against the brake wheel thus the wheel is gripped at each side with an
equal amount of pressure and the loom stops at once and with less wear and tear than
heretofore.

I, JOSEPH TURNER of 32 Wellington Street, Mill Hill Blackburn in the County of
Lancaster, Mechanic, 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 :-
Heretofore the brakes of looms have been applied to the brake wheel directly
underneath the shaft of the brake wheel and to one part of the brake wheel only and
consequently when the brake was applied great strain was put on the top of the
shaft of the brake and on the bush of the loom shaft.
According to this my invention I employ a brake lever as ordinary on one end of
which is a wedge shaped brake faced with wood, leather or other suitable material.
Behind the brake wheel and underneath the shaft thereof is a horizontal bar supported
and free to move to and fro in brackets bolted to the side frame of the loom.
On the horizontal bar at each side of the brake wheel is a piece of wood or other
material which acts as a brake shoe on the brake wheel and a stud in the horizontal
bar acts as a fulcrum for the wedge shaped brake shoe.
The action is as follows: When the brake is to be applied the handle of the brake
lever is thrown out or "knocked off" thus raising the wedge shaped shoe on the
opposite end of the lever which shoe presses against the brake wheel and at the same
time the other side of the wedge shaped shoe acts on the horizontal bar sliding the
same in its bearing and thus brings the other brake on the other end of the horizontal
bar against the brake wheel, thus the wheel is gripped at each side with an equal
amount of pressure and the loom stops at once and with less wear and tear than
heretofore.
Such being the nature and object of this my said invention the following is a
complete description of same reference being had to the accompanying drawings.
Fig. 1 is an elevation of part of loom end illustrating application of our invention.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is a detail enlarged.
At 1 is a rod connected with the setting on handle, 2 a horizontal lever, free to
work on the stud 3 as fulcrum. At end of lever 3; is the upright 4, head 5 of which
is wedge shaped, the inner face 6 forms the brake surface, the other side 7 of the
wedge forms an incline, at 8 is the horizontal bar, behind the fly wheel 9 and under
its shaft 10. The end 11 of the bar 8 is bent as shewn in plan and supported by
bracket 11º in which it is free to slide endwise, and to the opposite end 12, of the
bar 11, is attached the other brake 13 by bracket 13*.
The action is as follows:
When the loom "knocks off" or the setting on handle, is thrown out, the rod 1
lowers, whereon the lever 2, tilts on its fulcrum 3, and the wedge shaped head 5, is
forced upwards bringing the brake surface 6 upon the rim of the wheel, whilst the
2

page_text: incline surface 7, simultaneously bears on, and against the inclined head of the stud 7ª
fixed to the bar 8 and which is thereby forced laterally, in direction of the arrow, and
the brake 13, is thus drawn and applied to the opposite side of the rim, the two
brakes thus gripping the wheel between them. The degree of grip or power of the
brakes is readily adjusted to requirement by the moveable weight 14.
When the upright 4 falls the finger 6" pressing against the stud 7° forces the bar 8
laterally in the direction opposite to that indicated by the arrow and thus removes the
brake 13 from the wheel.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what 1
claim is :
The tilting lever 2 wedge shaped brake shoe 5 cross bar 8 and brake shoe 13 when
in combination and connected with the setting on handle, by rod 1 or other like
connection and for purpose described and as illustrated by drawings annexed..
Dated this 11th day of July 1888.
