Application nea November 12.1891. serai No. 411,674. (no man.)

.To all whom it may concern:

Be it known that I, JOHN E. WINDLE, of Worcester, county of Vorcester, State of Massachusetts, have invented an Improvement in Cloth-Guiding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In cloth finishing, drying, tentering, and kindred machines feeding belts or chains are provided for feeding the cloth, and in most instances said feeding belts or chains carry tenter hooks or spurs. It is intended that these feeding-chains shall engage the edge of the web, and as the web varies slightly in width and as its line of feed to the machine varies the said feeding-chains must be moved laterally or transversely to the line of feed or they will release their hold on the cloth or will engage the cloth at some distance from the edge, and thereby injure the cloth. In all instances, so far as I am aware, these feeding-chains have been moved transversely to the line of feed by hand and require constant watching, as well as very careful manipulation.

This invention has for its object to construct an attachment for cloth-finishing or kindred machines whereby the feeding chains or belts are moved transversely to the line of feed automatically and independently of each other.

My invention consists, broadly, in feedingchains for cloth-finishing and kindred machines movable automatically and independently transversely to the line of feed, and also in certain general forms of construction of parts whereby the feeding chains may be moved automatically and independently transversely to the line of feed, which movement is controlled by the cloth.

Figurel shows in front elevation an attachment for cloth-finishing and kindred machines embodying this invention. Fig. 2 is a plan view of the parts shown in Fig. l; Fig. 3, an enlarged cross-section of the parts shown in Fig. 2, taken .on the dotted line x Q0; and Fig. 4, an enlarged detail to be referred to.

The shaft a, having its bearings in the side frames a a of the machine, has loosely mounted upon it two sprocket-wheels, as 0.2, which are secured to hubs or collars a3, provided, as shown, with circumferential grooves a5. Feeding-chains b n are fed over the sprocket-wheels a2 of, they being herein shown as ordinary sprocket-chains provided at one side with tenter-hooks h; n; yet, so far as my invention is concerned, any other form of feeding-chain may be employed. Links c o are secured at one end to blocksc o and at the other end are formed as yokes to embrace the hubs as, suitable spurs or projections c2 o2 being provided on the arms of the yokes, which enter the circumferential lgrooves a5. The blocks c o are dovetailed, as shown in Fig. 3, and mounted on and adapted to slide freely on a stationary frame or bar cl, secured at each end to the side frames ct a. At or near each end ofV the stationary frame d a suitable support d is erected, which furnishes bearings for a rod or bar cl2, to the ends of which are rigidly connected short links cl3 cl3, the outer ends of which are connected by a rod or bar d4, arranged parallel to the rod or bar d2. The rod or bar d4, which serves as a presser-bar, as will be described, is hence pivotally connected to the supports d d.

The rod or bar d4 rests upon the extreme edge of two plates e p, which are secured by screws 2 or otherwise, respectively, to the blocks c o', said plates having curved surfaces, as shown in Fig. 3, and being each provided with two parallel slots extending transverselyto the length of the plates.

Two feelers f f are pivotally connected to the block c at 4, the upper ends of which are provided with a series of teeth, which just protrude through the slots in the plate e, and arms 5 are formed integral with or secured t0 the feelers, which arms are connected by links f2 f3 to one end of a plate made to represent/and acting as two oppositely-extended pawls f1 f5, pivoted at f6. As herein represented, the pawl f5 has a post or stud on it, to which both the links f2 f3 are connected. The plate o is also provided with two feelers having arms, which are connected by links to a plate made to act as two oppositely-eXtended pawls, the same as theparts f roo ffzfflf, (shown in Fig. 4,) and connected to the block c.

A rack-bar g is mounted on the stationary frame (l, which rack-bar is connected at one end by a crank-arm g to a cranlepin or eccentric stud g2 on ashaft g3, carrying a pulley g". As the pulley g'l is revolved the rack-bar g is reciprocated longitudinally.

The pawls j4 f5 on each block c o are adapted to engage and disengage the raf'kbar g, and when in engagement the said rack operates to move the blocks, and hence the rack, reciprocated continuously, as shown, constitutes a power-driven operating mechanism for moving the blocks, while the pawls and feelers serve as connections between the blocks c o and the rack. The cloth is fed forward over the rod d2 and under the rod (Z4, so that the edges will follow along over the feelers and be engaged by the tenter-hooks or other feeding-chains. Then the edge of the cloth engages the feeler f only, the pawls f4 f 5 are held outot engagement with the reciprocating rack g; but if the edge of the cloth should be worked or moved over onto the feeler f' the pawl f5 will be lifted so high as to throw the pawl f'L into engagement with the rack, and as the said rack reciprocates the block c will be moved toward the end frame a until the cloth leaves the feeler f and covers only the feeler f, and if the cloth should work or move off of the feeler f the pawl f5 will fall into engagement with the rack g, and as the said rack reciprocates the block c will be moved in the opposite direction or away from the end frame c. Hence it will be seen that the feelers are controlled by the moving cloth and serve as the devices which determine when the blocks shall be moved and in which direction. The operation of the feelers connected to the block o is the same. It will be observed that the blocks c and o are thus moved automatically and entirely independently of each other, and the feeding-chains connected therewith will be correspondingly moved, which movement is transverse to the line of feed.

I do not desire to limit myself to the parin ticular construction shown of the connecting mechanism between the feeding-chains and blocks, nor between the blocks and powerdriven mechanism; nor, in fact, do I desire to limit my invention to any particular construction by which automatic and independent motion transversely to the line of feed may be given to the feeding-chains.

I claiml. In a cloth-finishing or kindred machine, a feeding-chain and a carrier which is movable transversely to the line of feed, combined with mechanism to move said carrier transversely and devices controlled by the cloth which determine when said carrier shall move and in which direction, substantially as described.

4E. In a cloth-finishing or kindred machine, two feedingchains, independent supports therefor, powerdriven operating mechanism comprising a reciprocating bar, and independent connections between said bar and chains to move one or both of them with the bar transversely to the line of feed, substantially as described.

In a cloth-finishing or kindred machine, two feeding-chains, independent carriers therefor movable separately and transversely to the line of feed, and a power-driven mechanism to move the carriers, combined with connections intermediate said mechanism and each carrier, controlled by and partially supporting the cloth, substantially as described.

6. In a clotlrtinishing or kindred machine, a cloth-feeding chain and a transversely-movable blocl, with which said chain is connected, combined with a powerdriven operating mechanism and two feelers controlled by the cloth carried by said block intermediate it and the power-driven operating mechanism and adapted to automatically engage and disengage the said power-driven operating mechanism when the cloth contacts with both or only one of the feelers, substantially as described.

7. In a clotlrnishing or kindred machine, two cloth-feeding chains and blocks with which they are connected, combined with a power-driven operating mechanism and two feelers controlled by the cloth and carried by each block intermediate it and the operating mechanism and adapted to automatically engage and disengage the said power-driven mechanism when the cloth contacts with both or only one of said feelers, respectively, substantially as described.
