SPECIFICATION forming part of Letters Patent No. 492,144, dated February 21, 1893.
Application filed May 2l, l890. Serial No. 352,636. (No model.)
To all whom t may concern:
Be it known that I, GEORGE S. COX, a citi-- zen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
The object of my improvement is to enable the rapid and ready production of blind passes or the formation ot' warp without filling, so that at Ithe ends of the fabric, such as towels, I can obtain a sufficient extent of warp to produce fringe.
My improvement consists in certain attachments 'to looms whereby the tension on the warp is released, and, at the same time, the sand roller is caused to move rapidly so as to carry forward a sufficient extent of Warp to form the fringe of any desired length.
In the drawings:-Figure 1 is a side elevation of a portion of a loom embodying myinvention. Fig. 2 is a front elevation of portion of loom. Fig. 3 is a side elevation of portion of loom,-the side opposite to that of Fig. l. Fig. 4 is a perspective View of detached parts. v
Similar letters denote similar parts.
A is the ordinary shuttle box lever which is connected to the lifting rod aso as to bring the desired shuttle into position to be operated by the picker staff. This lever is operated under the control of, the pattern chain B, which has projections or lugs of differentl heights and said pattern chain generally moving one sprocket for every two picks. Said projections act on the weighted feeler lever b which is connected to the rod b', which in turn is connected to the ordinary anchor b2, which anchor is given a vertical reciprocatory motion in the ordinary manner.
On the box lever A are a series of steps a', a2, duc. and the weighted feeler lever b brings the anchor into such position that it strikes different steps depending upon the extent of projection upon the pattern chain, and by this means the desired box is brought into position to be acted upon by the picker staff as in an ordinary loom.
C is the sand roller which moves the cloth forward as it is made.
d is the shoe attached to the lifting rod a, upon which the shuttle box lever acts to lift the shuttle box.
dis a ring loosely surrounding the lifting rod and resting upon this shoe. To this ring is attached a spring d2, and a string or chain d3 also is attached to this ring d', which string or chain passes over a pulley d4 on the front of the loom on the back of the breast beam d5 and passes along thevback of this breast beam to the opposite side of the machine to pulley d6 and passes around a roller c2@ on the shaft e and over pulley dl attached to the lever E, on the gear shaft e. Connected to this lever are the pawls e', e2, one on each side (see Fig. 4). The string or chain passes from the pulley d6 around the shaft e and over pul l ley d", on the lever E and is connected to the pawls e', e2, it dividing out to connect with them.
F is a gear wheel on the shaft e, and F, F2 are two ratchet wheels on said shaft, the pawls e', e2 being adapted to work in the ratchets F', F2 respectively. The ratchet F2 has a projection f on the surface which rests in a slotf in the gear wheel F, and when said ratchet is at rest is at the point f2 of said slot. The lever E has the link G connected to it at its upper end, the other end of the link Gbeing connected to the crank disk G which is mounted upon the cam driving shaft H, which shaft is operated through the gears H2, P3, by the main driving shaft P4.
Upon the ratchet wheel F is the projection J, to which is attached a rope or chain j, which passes over the pulleys lc and lo and has its Aother end connected to the weighted lever L,
which is used to put the proper tension on the warp upon the warp beam M. The gear wheel F gears into the wheel N upon the shaft ln.. Upon the same'shaft n is the gear wheel O which works in the gear wheel P upon the shaft p. The gear wheel P upon the shaft p works in thev gear wheel P2 upon the sand roller and during the ordinary action of the loom all these gears are revolved continuously by the usual take-up mechanism. The spring cl2 holds the string or chain d2 so that the pawls e and e2 are out of engagement with their corresponding ratchets. The string or chain is inactive in the ordinary operation of the loom, but upon the pattern chain are placed at the desired positions lugs of a greater height than is necessary to bring any shuttle box in use into position; and this, through the intervention of mechanism here inbefore described, causes the lifting rod a to raise an extra height. This is done at the end of the construction of a piece. This causes the chain d2 to become slack, and the pawls c', e2 are allowed to drop into their respective ratehets. As the leverE is actuated by the cam shaft, as hereinbefore described, the ratchet wheels revolve, which causes the string or chain j to be moved forward, lifting the weight L from the warp, and the ratchet F2 revolves the gear wheel F, which, by the gearing described, causes the revolution of the sand roller to be accelerated, bringing forward the warp and enabling fringe to be formed rapidly and satisfactorily. The cord (Z3 passes around the shaft e before it passes around the pulley (Z7, so that the length of the said cord d3 is constant and is not affected by the movement of the lever E. The connection between the gear wheel F and the ratchet F2 is made as described, so that the movement of the ratchet F will lead that of the gear F and the weight will be taken off the warp before the sand roller is operated.
A spring Sis at one end attached to the ratchet F', and the other end is attached to the floor or other fixed place, so that if sufficient fringe be not made in one motion of the lever E, and the pawls are moved back on the ratchet, the tension produced on the spring by the forward movement of ratchet F' will pull the said ratchet back the distance it moved forward.
The ratchet F2 is provided with a hub having a friction face which is kept in contact with the ratchet F so that when the ratchet F is pulled back by the spring S the ratchet F2 will also be moved back a distance equal to the length of the slot F' in the gear F, so that the ratchet F2 will move that distance before it operates the gear wheel F, thus enabling the weighted lever L to be released from acting on the warp beam before the gear wheel F is operated, so that the tension on the warp is released before the sand roller is operated.
Instead of operating the lever E from the cam driving shaft, I can operate it from the main driving shaft directly.
Then the machine is operating to weave the fabric, the ordinary means are used for operating the sand roller so as to take up the woven fabric.
Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
l. The combination of a sand roller, a warp beam, a tension device ou said warp beam, a
driving shaftoperatively connected to the sand roller and to the tension device and mechanism whereby the tension device may be released from the warp beam in advance of the movement of the sand roller.
