PROVISIONAL SPECIFICATION.
Improvements connected with the Taking-up Mechanism of Looms
for Weaving.
I, JAMES HOLLINGWORTH, of Dobcross Iron Works, in the County of York,
Power Loom Maker, do hereby declare the nature of this invention to be as
follows (which invention has been communicated to me from abroad by George
Frank Hutchins of Worcester, United States of America, Machine Maker):-
This invention relates to the take-up mechanism of looms, but more particularly
to the take-up mechanism for plush, or velvet looms, where the fabric is woven
double, or with two backs connected by the pile; such said pile being afterwards
cut on the loom, and each piece of cloth taken up by its own particular take-up
roller.
The object of my invention is to give to the ratchet of the take-up mechanism
an almost continuous motion, by means of a double pawl, or two pawls, which are
driven from the rocker pin or other "going-part" of the loom; one pawl moving
the ratchet at the forward beat of the slay, and the second pawl moving the ratchet
at the backward beat of the slay.
The arrangement of the mechanical parts is somewhat as follows:-A lever arm
is made to go backward and forward at each beat up of the slay, such lever arm
carrying a pawl in gear with a ratchet wheel and on the forward motion of the
said lever arm the pawl takes up a tooth or so in the wheel, but on the backward
motion of the lever arm, another pawl carried by a bell crank form of lever and
operated by the lever arm is made to take up a tooth or so in the ratchet wheel,
whereby it is made to move at cach motion of the lathe sword, thus imparting an
almost continuous rotary motion and making the take-up of the fabric more
uniform than at present, as instead of each pick being taken up at one motion it is
divided into motions.

COMPLETE SPECIFICATION.
Improvements connected with the Taking-up Mechanism of Looms
for Weaving.
I, JAMES HOLLINGWORTH, of Dobcross Iron Works, in the County of York,
Power Loom Maker, 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 (which invention has been communicated to me
from abroad by George Frank Hutchins, of Worcester, United States of America,
Machine Maker):
:-
This invention relates to the take-up mechanism of looms, but more particularly
to the take-up mechanism for plush, or velvet looms, where the fabric is woven
double, or with two backs connected by the pile; such said pile being afterwards
cut on the loom, and each piece of cloth taken up by its own particular take-up
roller.
The object of my invention is to give to the ratchet of the take-up mechanism
an almost continuous motion, by means of a double pawl, or two pawls, which are
driven from the rocker pin or other "going-part" of the loom; one pawl moving
the ratchet at the forward beat of the slay, and the second pawl moving the
ratchet at the backward beat of the slay.

page_text: In order that this invention may be more clearly understood, I will make
reference to the accompanying sheet of drawings illustrative thereof, wherein
Fig. 1 is a side elevation of the improved take-up mechanism detached from the
loom, and
Fig. 2 is a partial end elevation of the same.
Two
In the accompanying drawings, the dotted lines 1 represent the double woven
fabric as it comes from the loom, before it is divided or cut apart, and 2 represents
the sections of fabric after it has been cut apart, such sections 2 being afterwards
wound upon the taking up beams 3 and 4 of Fig. 1. On the ends of the taking up
beams 3 and 4, are secured worm wheels 5 and 6 gearing with and driven by
worms 7 and 8 fast on the upright shaft 9. A handle or crank arm 10 is secured
on the top of the upright shaft 9, and the bevil wheel 11 (see Fig. 2) is fixed on
the lower end of the said shaft 9, and made to gear with the bevil wheel 12 secured
on the horizontal shaft 13, on which is also fixed a ratchet wheel 14.
arms 15 and 16 are placed loosely on this shaft 13 to which arms are pivotted
pawls 17 and 18 which engage with the ratchet wheel 14. The lower arm 16 is
provided with a flat spring 20, which presses against a knob 19 projecting from
the pawl 18 for the purpose of holding the said pawl 18 in contact with the ratchet
wheel 14. The oscillating stud 21 carries a lever arm 22 provided with a slot 23,
in which is an adjustable stud 24, from which there extends a connecting rod 25
attached to the pawl arm 15. This connecting rod 25 is also made with a slot 26
for receiving a stud 27, adjustable therein either backwards or forwards, from
which stud there extends a connecting rod 28 attached to the pawl arm 16.
The operation of the mechanism is as follows:-The stud 21, which is intended
to represent the bottom of the lathe sword, oscillates backward and forward with
each pick of the loom, and on the forward motion of the lever arm 22, the
connecting rod 25 is moved in the direction of the arrow a, causing the pawl 17 to
operate the ratchet wheel 14, but on the backward stroke of the lever arm 22, the
connecting rod 28 is moved in the direction of the arrow causing the pawl 18 also
to operate the ratchet wheel; from which it will be seen that the said ratchet
wheel is moved forward, both when the slay is beating up and also when it returns.
The rotary motion of the ratchet wheel 14 is transmitted through the horizontal
shaft 13 bevil wheels 12 and 11 to the upright shaft 9 and through worms 7 and 8
to the toothed wheels 5 and 6, and consequently to the taking up beams 3 and 4
which take up fabric in an even and regular manner. It will be observed that the
length of stroke which the connecting rods 25 and 28 are made to take, can be
regulated by the slots 23 and 26.
By using the pawls 17 and 18 and operating them in the manner described, an
almost continuous rotary motion is imparted to the taking up beams, whilst the
rotary movement of the said beams, which has hitherto been effected at one move-
ment of the taking up pawls is now divided into two movements.
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
Firstly. In the taking up mechanism of looms, the use of two connecting rods 25
and 28 operated by the going part of the loom; in combination, with two ratchet
pawls 17 and 18 arranged and operated substantially as shewn and described.
Secondly. In the taking up mechanism of looms, the use of two adjustable
connecting rods 25 and 28, the opposite movement of which operates the ratchet
wheel 14 in combination with the loose lever arms 15 and 16, pawls 17 and 18
ratchet wheel 14 operated and combined all as described and shewn in the
drawings.
