Specification forming part of Letters Patent No. 124,288, dated March 5, 1872.
Specification describing anew and useful Improvement in Hat-Looms, invented by JOHN van DUssEN REED, of the city of New York, in the county and State of New York.
The invention consists in combining a snitable let-out mechanism with each warp-carrier, which has a large iiat spool carrying a considerable length of yarn. The spool above mentioned carrying the warp-yarn is fitted to rotate freely in guides on the warp-carrier, and so that it can be readily removed and replaced when exhausted. The yarn is led from the spool to the let-out7 mechanism, and through a spring to a hole or guide at the front of the carrier, and thence to th'e center of the loom where all the warp-strands are connected to the cord, by which the said warp-strands are drawn down taut when the loo`m is putin work. The letout77 mechanism consists of a double acting spring-pawl' gearing with the teeth of a ratchet-wheel, around which the warp-thread is carried, so as to be held firmly thereby and let out in a regular manner by the rotation of the wheel, which moves to the extent of one tooth only at each oscillation of the doublelactingpawl-lever, which is actuated by a lifting-roller mounted on an arm carried on the shuttle-carriage. The ratchet-wheel is carried on a pivot fixed to a sliding piece working in a slot in the warpcarrier, and moved by a lever, also pivoted to the carrier, by which the let-out mechanism may be thrown out of gear when it is necessary to let out a considerable length of warp at once, as for commencing another hat, when all the warp-threads have to be gathered into the center, as mentioned below. This lever may be operated directly by hand, or indirectly by adevice mounted on an arm iixed to the shuttle-carriage, and working in a somewhat similar manner to the lifting-roller above referred to. After a hat has been woven, the letout mechanism is thrown ont of gear, as above mentioned, and the woven hat is drawn down through the cup of the loom, which is bottomlcss, by which action the warp-strands are drawn out or unwound from their spools. They are then gathered together in the center ofthe loom, and held by a suitable device just above the hat already woven, and the let-out mechanism, having been again put in gear, the loom is ready to start again to weave another hat, and
so on continuously until the spools in the warpcarriers are exhausted.
The cord heretofore used in the circular-hat machines to draw down the warp is attached to the above-mentioned device, which binds the warp-strands together at the center of the loom to draw down the hat as the weavingprogresses; and heretofore the warps, as far as I am aware, have been used in short lengths.
Figure l is a side elevation ofthe warp-carrier with the parts in combination. Fig. 2 is a plan or edge view of the same; and Fig. 3, a side elevation, showing a modified arrangement of devices for connecting and disconnecting the ratchet-wheel with the let-off lever. Figs. 4 and 5 are details of the said apparatus; and Fig. 6 is a sectional elevation of one-half of a circular hat-knitting loom, for which my improvement is designed.
The saine letters of reference indicate the same parts in all the iigures wherever they recur.
Referring rst to Fig. 6, which represents so much ot' the machine, for which the improve ment is intended, as is necessary to illustrate its application, A is the bed-plate of the machine; B, standards for supporting the upper frame and the stationary ring-plate C. E is the stationary ring for supporting the lower stationary mechanism, and is iitted to the bed-plateA, near the center ot' the loom, in the form of a cylinder, as a guide orbase for another cylinder, F, to revolve around it. This ring supports a ring, F2, which revolves and carries the shuttlecarriage, Ste., while the stationary ring E supports the stationaryring E2, on which the lower plates or grinders al for the warp-carriers are mounted, while the upper plates a2 are supported on the ring G. The said warp-carriers are worked back and forth from one set to the other of these plates for forming the studs bythe grooves formed by the annulaibends or rings D2, forming the principal part of the shuttlecarriage, which is carried by the rln g F2, said carriers having aproj ection, a, working in the said grooves. e, d3, g3, and 7a4 constitute the shuttie-carrier. G is the bracket, attached to the annular rings for supporting a-nd carrying the shuttle-carrier, and J represents the wheel for operating the let-oi levers g. a., Fig. l, is the warpcarrier, and b is a spool of large dimen sions, held in guides c xed on the carrler a. These guides are made with iianges, which are received between the two disks of which the spool b is composed, as shown in Fig. 2. TheY spool is simply slipped between the guides, and rests on a stop or small friction-roller, d. Z is the ratchet-wheel of the let-out mechanism. It is carried on a pin fixed to a slide, f, grooved and fitted in a slot in the carrier, and the rotation of the wheel is controlled by a double-acting sp1-in g-pawl, g, 4pivoted at 7L to the carrier, and one or other tooth of which is always in gear wit-l1 wheel e. i' is a yoke, in which the tail end of the pawl works, andj is its spring. \Vhen the lifting-roller77 J, Fig. 6, passes under the carrier it raises or oscillates the pawl g, and, therefore, fulfils the same function in the case as in the aforesaid machine-namely, to let out the warpwhich is effected by the rotation of the ratchet-wheel e, which is released and moved, and lets out the warp to the extent of one tooth at each oscillation of pawllever g. The warp-thread is shown in dotted lines in Fig. 6, and full lines in the other figures. It is led from the bobbin or spool b completely around wheel e,- thence through a spring, k, to a hole, k1, in the end ofthe carrier, whence it is taken to the center of the loom. The deection of spring k serves to compensate for the shortening by corrugation of the warp in weavin g. lis a lever, pivoted at its extremity to the carrier. This pivoted end is made of the angular form shown, and works in a corresponding angular recess made in a plate, m, fastened to the slide f. By moving the lever l to the position shown in dotted lines, Fig. 1, the wheel e will be drawn back out of gear with its pawl g, thereby permittin g any desired quantity of warp to be drawn freely off the bobbin. The wheel e is grooved to receive the warp-thread, and one edge only of its periphery is serrated, the othY er being plain. The object of making lever l angular at its pivoted extremity is to prevent it being shifted by the tension of the warp on the ratchet-wheel e. Vhen the lever Z projects above the carrier, as shown in Fig. l, it must be moved or oscillated as required by hand; but the let-out mechanism may be arranged as shown in Fig. 3, in which case a device, shown in Fig. 5, may be employed to shift the lever Z. It consists of a grooved guide, n, jointed to the end of a rod, o, carried by the same or a similar bracket on the shuttle-carriage to that which supports the lifting-roller. rlhis guide runs round the loom in advance or in rear of the liftin g-roller, and is pivoted at its forward end to rod o, which is bent, as shown, Fig. 3, and the said guide is capable of being readily shifted to either position shown by means of a lever,
p, and sliding rod p operated by hand. The dotted lines show the second position of the ends of levers l, which are shifted from one po sition to the other by the guide in its passage,
y as shown by said dotted lines.
Having thus described myinvention, I claim as new and desire to secure byLetters Patent- In a loom for weavin g hats, the combination, with the carrier a and spool b, of the improved let-out mechanism, arranged and operating substantially as hereinbefore described and shown in the drawing.
rlhe above specification of my invention signed by me this 18th day of August, 1871.
JOHN VAN DUSSEN REED.
