PROVISIONAL SPECIFICATION.
Improvement in Cloth Taking Up Motions for Looms.
I, JAMES HOLGATE of Number 3 Elm Street Burnley in the County of
Lancaster Manager do hereby declare the nature of this invention to be as
follows:-
::
My improvement consists in an arrangement for "letting back when the weft
breaks, so as to prevent thin and thick spots or cracks in the cloth.
I place
friction discs on the shaft (preferably the one which carries the ratchet wheel), one
part of these discs is keyed on the shaft and the other rides loose upon it, being
pressed against the face of the fixed disc by a thin steel washer which acts as a
spring. On the part which rides loose projects a lug or arm, capable of move-
ment between two adjustable fixed studs. When the pawls are released in the
ratchet wheel, it revolves through the small arc and lets back the cloth."
"
The lug or arm on the loose part of the friction can be weighted if found
necessary and thus help back the train of wheels, which are found to be trouble-
some especially when weaving light fabrics, the drag not being enough to overcome
the friction in the train.

COMPLETE SPECIFICATION.
Improvement in Cloth Taking Up Motions for Looms.
I JAMES HOLGATE of Number 3 Elm Street Burnley in the County of
Lancaster 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 :-
The object of this invention is to prevent thin and strong places in cloth, caused
generally by carelessness or mistaken judgment of the weaver.
For this purpose I place on one of the shafts of the taking-up mechanism-
preferably the first motion or ratchet wheel shaft-two discs, one of which is fast
on the shaft, whilst the other rides loose upon it, and is pressed against the fast
disc by a spring washer. On the periphery of the loose disc is attached a pin or
lug, arranged to work between two adjustable studs. When the loom is set to
work, the loose disc and pin tend to revolve in the direction of the taking-up but
is checked on reaching the higher stud, and thus the friction discs slide on each
other. Upon the weft breaking, the loom and taking-up mechanism proceed for
several picks. To make good this loss the weaver-by means of suitably arranged
parts-releases the pawls in the ratchet wheel, which allows the pin or lug to fall
to the lower stud but still prevents it by means of the friction from recoiling
too far.
The projecting lug or pin can be weighted-or have a spring attached—according
as may be found necessary in each individual case, to help the recoil.
In lieu of a disc to form one part of the friction, any one of the wheels used in
the train might be suitably arranged for the same purpose.
The drawing on Sheet 1 is a part sectional plan, whilst that on Sheet 2 is an
elevation. S is a shaft on which is fastened the ratchet wheel R, the pinion
wheel P-which gears with the taking-up mechanism-and the friction disc F.
The shaft S works in and is carried by the bracket B. The loose disc of the
friction part D is held against the mill board washer M (which in turn presses

page_text: against the fast friction disc F) by a steel washer W, the pressure of which is
adjusted by the checknuts N. N. The tail-pin or lug L is screwed into or attached
to the loose disc D, and is limited to revolve between the adjustable studs 01
and O². The studs O¹ and O2 are fixed to the bracket B which bracket has a
radial slot in it to allow the studs (0) and O2 to be brought as close as may be
desired. When the loom is in action the pin or lug L rises and is carried against
the stud O³, and as the "taking-up" proceeds the discs F and D slide on each
other, but when the pawls or catches are released from the ratchet wheel R the
tail-pin or lug L falls to O¹, and thus measures or limits the amount of recoil,
whilst at the same time the tail-pin or lug L-owing to its advantageous position—
helps the recoil of the mechanism.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
The individual parts lettered F, D, M, W, N, L, O' and O2, and their combined
arrangement, substantially and for the purpose as set forth in the foregoing
Specifications and shown in the accompanying drawings.
Dated this 8th day of April 1892.
