CHARLES THOMPSON 2 St James's Place Otley Road Baildon in the County of
York (Mill Furnisher) do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in Stop rods Brake device letting off and
taking up motion, the brake device being applicable to Fast Reed Looms.
According to my invention the stop rod is made with the collars and fingers and
stopper, instead of being welded thereto are cast separate and fixed in their respective
positions by screws or pins thus enabling their more easy and ready repair. The
finger operated upon by the shuttle box swell, is a steel spring secured to the stopper
by means of cast iron stopper tongue.
The braking device consists of a compound brake to clip both sides of the driving
pulley, the back brake lever has its fulcrum above the centre of the pulley and is
mounted on a stud secured to the end frame of the loom. The lower end of the lever
is connected by rod to a frog in front of the slay, and the upper end is connected by
rod to the upper end of the vertical arm of the front brake lever, the latter is shaped
the fulcrum being at the junction of the arms, mounted on a stud, fixed in the end
frame of the loom below the centre of the pulley, one horizontal arm projects in front
of the loom with a handle formed thereon and is held in position by the stop handle
the other horizontal arm projects under or on the side of the driving pulley and has a
weight suspended therefrom.
At each forward movement of the slay, the stopper clears the frog unless a trap
occurs, then the stopper catches the frog and draws by means of the connecting rod
the back brake lever and by the connections the front brake lever against each side of
the driving pulley simultaneously, thus arresting the motion of the loom.
Within the end frame of the loom are two catch wheels, actuated by a slotted lever
catch commonly known as the monkey catch lever, which is operated by the sword or
going part, on one catch wheel boss is a Bevil wheel, which drives a bevil wheel on a
shaft having a worm at its opposite end gearing with a worm wheel on the letting off

page_text: roller, when required for two warps the wheel on the top roller gears with an inter-
mediate wheel the latter drives another letting off roller, each letting off roller forms
one of a set of three, two of which in each set are geared, the remaining roller forming
a tension roller, one warp beam being placed above its set of rollers, and one warp
beam placed below its set of rollers. The warp in each case passing over two of the
rollers thence to the back bearer, on the same boss as the catch wheel and Bevil
Wheel is a change wheel which gears with a change wheel mounted on a stud fixed in
a swing plate, the latter change wheel is for purpose of releasing and taking up the
warp, by hand, the stud may also be used to form the axle for an addittional gear in
taking up the cloth on the piece beam.
The piece beam being driven by one of the catch wheels above referred to, which is
mounted on a stud that passes through the boss of the catch wheel for letting off the
warp, and at its outer end is a change wheel which gears with the ordinary change
wheels forming the taking up wheels.
For putting extra tension on the warp beam, I pass a cord around the neck of the
beam one end secured to the loom frame and the other to a lever, close to its
fulcrum and at the opposite end of the lever I place a spiral spring one end connected
to the lever the other to the loom frame.

page_text: I CHARLES THOMPSON 2 St. James's Place Otley Road Baildon in the County of
York, (Mill Furnisher) 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 :-
Fig. 1 is end elevation of Loom shewing mechanism for letting off the warp and
taking up the cloth, Fig. 2 plan of Fig. 1 Fig. 3 sectional elevation of back rollers
and warp beams, Fig. 4 enlarged view of catch wheels Fig. 5 plan of Fig. 4 with
catches removed Fig. 6 front elevation of Stop rod Fig. 8 back elevation shewing
Tension lever. Within the end frame 1 of the loom are the catch wheels 2, 3, 4, the
wheels 2, 3 are actuated by slip catch 5 on lever 6, operated by going part 7, the
wheel 2 is secured to the shaft 8 and at outer end is spur wheel 9 which operates by
wheels 10-11 the cloth roller wheel 12, the catch wheel 3 is mounted on the boss 13
of the bevil wheel 14, drives by means of the bevil wheel 15, worm 16 wheels 17, 18
19, 20, 21, 22 drives the rollers 23, 24, 25, 26, and thereby draws the warp from the
beams 27, 28, simultaneously with the taking up motion, 29 is wheel on boss of bevil
wheel 14 which gears with wheel 30 for taking up the warp by hand when required,
or the stud 31 on which the wheel is mounted may be used for an addittional gear in
taking up the cloth, the catch 33 is to prevent running back, 33 being mounted on
stopper rod and connected by cord 34 over pulley 35 to catch 36 the latter caused to
engage with the catch wheel 4 which has teeth in opposite direction to the catch
wheels 2, 3, thereby bringing back the cloth on the roller instead of taking up should
the weft break or other accident occur, the catch wheel 4 being mounted on the shaft 8
same as the catch wheel 2. 37 is the bottom and 38 the top warp.
Figs. 6. 7. at 39 is an ordinary Loom stop rod with loose fingers 40 instead of
being forged to form one piece secured to stop rod by cast iron brackets 41, 42 by set
screws. 43 is the loose collar.
Fig. 8. 44 is tension lever mounted on fulcrum 45, having spiral spring 46, con-
necting rod 47, levers 48, wheel 49 which secures one end of cord 50 which passes
round the neck of the warp beam 51.

page_text: Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is,
1st. The mechanism for letting off the warp and taking up the cloth herein
substantially described.
2nd. The loose fingers and collars on stop rods as herein described and illustrated.
3rd. The use in combination of a lever with spiral spring, and cord for purpose
herein described and illustrated.
