SPECIFICATION forming part of Letters Patent No. 578,008, dated March 2, 1897.

Application filed November 25, 1896'. Serial No. 613 ,364., (N model.)

At the forward end of the loo guides E there is arranged a horizontal guid eway 6, which projects somewhat inward on one side of the grooved guides E, as shown in Fig. 5. This guide e receives the rod F and leaves the collars or heads thereof extended over and in line with the grooves of the guide E. Small pawls m extend downward from an extension on the grooved guide E, so as to form a slight obstruction to the accidental rolling of a rod from the extreme end of the guide e, the position of the said rod when deposited by the hooks C being clearly shown in dotted lines in Figs. 3 to 6. Normally the grooved guides E are filled with a series of parallel rods F, and in the operation of the machine a rod is forced into one end of the said guides E simultaneously with the removal or discharge of a rod at the opposite end, so that there are always the same. number of rods acting upon the fabric W, which is fed through the chamber and sustained in loops upon the said rods, as clearly shown in Fig. l. The fabric enters the chamberA between feeding-rollers I I, and after being treated emerges by being drawn out of the chamber between the plates I I.

Whentherod is brought to a position upon the guide 6 by the endless conveyers, it is left there,while the hooks continue to travel, and While this operation is taking place the fabric W' is descending to form a new loop. \Vhen theloop is. formed, the pushers 7c are moved forward so that they strike the heads or collars of the rod and move it under the pawl and forward again st the rods within the guides E. The heads or collars of the various rods properly space them and prevent the cloth from rubbing upon itself. Then the pushers move forward, they act upon. both ends of the rod alike and exert a sufficient force tomove the entire series of rods through or over the guides. The rod so moved by the pushers is forced under the pivoted frictionfingers g, which thereby hold the cloth from slipping, over the said rod and also insure its further feeding to form a new loop. These friction-fingers are veryclearly shown in Fig. 8, in which we have the fingers proper, g, adjustably secured to the free end of a bellcrank arm or lever G, provided with an adjusting-screw i, to adjust it so as to limit the downward movement of the fingers g. A weight G is adjustably clamped to the arm G, so as to exert any desired tension upon the fabric. There are a number of these fingers employed, as shown in Fig. 2, and they are all connected to a cross-beam U, which also carries the guides E.

The pushers 7c are secured to reciprocating frames K, provided with internal racks K K facing each other, and are adjustable at k to compensate for wear. A transverse shaft L has secured to it segmental gears M and N, the former adapted to engage with the rack K and the latter with the rack K It will be seen that when this shaftrotates in the direction of the arrow, Fig. 3, the action ciprocates with great steadiness.

of the gear M with the rack K causes the pusher k to be moved with considerable rapidity forward to transfer the rod from the dot ted position to the solid position under the fingers G, and a further movement brings the gear N into operation with the rack K and returns the pusher at a slower speed. lVhen fully returned, it remains at rest fora period until the gear M again comes into contact with the rack K, when the operation is repeated. At the period of rest, however, a new rod is deposited upon the guides e by the conveyer. The frame K of the pusher is guided in a horizontal guide P, so that it re- The guide sprocket-wheels b are loosely supported upon the shafts L as they rotate under the action of the conveyors B in the opposite direction to the gears. As shown in Fig. 2, there are two of the shafts L, since it would be impracticable to run the shaft all. the way across on account of the descending fabric. These shafts, however, are connected by suitable gearing L and positively driven by a shaft L (See Fig. 2.) Gears L transmit power from the shafts L to the driving sprocketwheels I) at the top of the chamber.

Vtlhenever a new rod is pushed into position at the forward end of the guides E, a rod is liberated at the rear or discharge end and moves upon the inclined guides E until it comes to rest in a position to be automatically taken up by the hooks C, Fig. 1. Levers II, counterweighted at h, may be employed to offer a, resistance to the accidental displacement of the rods near the discharge end, so as to arrest any tendency to roll under the impact given at the forward end. The levers II are so shaped at the bottom as to rest gently upon the fabric on the rod to stop its slipping down and are provided with a lateral cam projection II, Figs. '7 and S, which acts upon the rod next to the rear and between the head and the fabric, so that when the rods are all moved forward this last-mentioned rod, acting upon the part ll, raises the lever H so that it shall not drag over the cloth or material being treated, but upon the passage of the rod under the cam part H it drops and once more allows the lever II to rest upon the fabric and last-mentioned rod. In this. way only one rod at a time is liberated and injury to the fabric prevented. As the rods are pushed toward the rear they are moved one at a. time from under the pivoted lever mechanism II and then by gravity roll upon the inclined guides E into position to be taken away by the hooks of the conveyor and ultimately returned below the fabric and brought up to theforward or feeding end previously described.

In place of using a pair of endless conveyers, as shown, it is evident that the conveyors may be formed in any suitable manner, so long as they have a capacity for conveying the rods through the chamber or from the discharge end to the feeding end of the horizon- ICO tal or grooved guides. Itis also evident that with regard to the guides E the upper flange may be omitted, so that, strictly speaking, they would not be grooved guides. In fact, any form of guides suitable to the purpose may be used.

It will be observed from an examination of Fig. 3 that the upper surface of the guide 6 is on a level with the bottom of the rods f, so that when moved forward their heads or collars are properly brought into position in the guides E.

In place of the particular means for pushing the rods into position above described I may employ a modification thereof, as indicated in Fig. i, in which a crank-wheel O is provided with a crank-pin 0, working in a transverse or vertical slot on a reciprocating bar or frame to which the pusher 7c is secured. It will be seen that upon rotating the crank O the pusher will be moved forward and backward at intervals, though in this case the movements will be uniform. By properly shaping the transverse groove for the crank-pin, however, the reciprocations may be made irregular, corresponding to that of Fig. 3.

In the modification shown in Figs. 5 and 6 the pusher 7c is secured to a frame S, having a rack P guided in a horizontal guide P and moved backward under the action of a weight T, attached to a chain 8, guided by a pulley S and connecting with the pusherframe S. The forward movement of the pusher is produced by a segmental gear E, meshing with the rack P and in all material respects corresponds to the gear and rack K of Fig. 3. In this manner the forward motion is positively performed with considerable rapidity by a rack and gear, while the return motion is performed by the action of gravity. At the end of the return motion the parts may remain at rest for a period of time during which a new rod is put into position upon the guide 6.

WVhile I prefer to make the gears M and N of different diameters and so set as to produce no appreciable period of rest at one end of the reciprocation of the frame K and a considerable period of rest at the other end, the motions may be made without the period of rest and also without the difference in speed, if so desired, by simply properly proportioning the gears.

In some cases, as in drying wall-paper or oil-cloths, the apparatus would be set up in a large room, which need not be tightly inclosed, as in the case of the chamber A. Hence I do not confine myself to the use of any inclosing chamber.

While I prefer the construction shown, I do not limit myself to the details thereof, as they may be modified in various ways without departing from the principle of my invention.
