TAKE-UP MECHANISNI FOR LOOIVIS.

SPECIFICATION forming part of I netters Patent NO. 424,142, dated March 25, 1890.

Application filed September 24, 1889. Serial No. 324,940. (No model.)

To all whom, it may concern.-

Be it known that I, PETER C. STADLER,of Paterson, in the county of Passaic and State of New Jersey, have invented a new and Improved Take-up Mechanism for Looms, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved compensating attachment for the cloth-beams of looms which is simple and durable in construction, very effective in operation, and serves to regulate the movement of the cloth beam in relation to the picks to compensate for the enlargement of the beam when the cloth is wound up.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying1 drawings, forming a part of this specifica-tion, in which similar letters of reference indicate corresponding part-s in both figures.

Figure 1 is a side'elevation of the improvement, and Fig. 2 is an end elevation of the same.

The cloth-beam A is provided on one end of its shaft B with a gear-wheel C, connected with a train of gear-wheels D, set in motion from a shaft E, mounted 4to turn in suitable bearings on the loom-f rame and carrying a ratchetwheel F, engaged by one, two, or more pawls G, pivoted on an arm H, fulcrumed on the shaft E, and tit-ting into a guide J, provided on one end with a slot J', on which is held adjustably a lug K, connected by a rope or other means with the lay of the loom, so that the movement of the lay imparts a swinging motion to the pivoted arm H, whereby the pawls G operate on the ratchet-wheel F and turn the shaft E. The latter, by its connection with the train of gear-wheels D, turns the gear-wheel C, so that the cloth-beam A is revolved and winds up the cloth.

It will be seen that as the guide J always remains on the pivotedarm H the stroke of the said guide and the said arm H will be the same, and the cloth-beam A will be turned the same distance for every pick of the shuttle. The guide J, however, is arranged in such a manner as to be moved on the arm H,

so that the throw of the pivoted arm H is decreased asV the winding up of the cloth on the cloth-beam A proceeds, so that the enlargement of -the cloth-beam by the winding up of the cloth is compensated for in relation to the picks made.

In order to shift the guide J, said guide is pivotally connected with links L, connected with the ends of a bell-crank lever N, having its fulcrum N arranged adj ustably in a slot O 'in the lower end of the lever O, fulcrumed on a pin O2, held adjustably in a vertical slot P of a plate P, forming part o'f the frame of the attachment. A spring O3 presses on the lever O, so as to hold thel same in a normal position. In the upper end of the lever O is formed a slot O, in which is held adj ustably a friction-roller Q, held in contact with the periphery of a spiral cam R, secured on a shaft or stud S, held in a bracket projecting from the plate P.

On the spiral cam R is secured a ratchetwheel T, adapted to bey engaged by a pin U, projecting from the face of a plate V, held adj ustably on one face of the gear-wheel C, secured on the cloth-beam shaft B. In order to make the plate V adjustable, the latter is provided with parallel slots V', through which pass screws \V, screwing in the arms of the said gear-wheel C. By slackening the screws W the plat-e V may be adj usted so that the pin U moves the ratchet-wheel T more or less at every revolution of the gear-wheel C. A pawl T engages the ratchet--wheel T, so as to prevent the backward movement of the latter. The spring O3, pressing against the lever O, always holds the rollerQ inv contact with the spiral cam R.

vThe operation is as follows: Vhen the cloth-beam is empty and the loom is started, the friction wheel or roller Q rests on the innermost point of the spiral cam R. The movement of the latter causes the guide J and the pivoted arm H to swing up and down, so that the ratchet-wheel F is turned, thereby setting the train of gear-wheels D in motion to turn the cloth-beam A to wind up cloth. When thecloth-beam A makes one revolution, the pin U on the plate V moves the ratchet-wheel T so that the cam R is shifted, and theiupper end of the lever O is moved IOO outward and the lower' end of the said lever 1s moved inward, causing the guide .I to move forward in the direction of the arrow a', whereby thc stroke of the arm II is shortened. This shortening of the stroke of the arm` II causes less movement of the gearwheels D and the cloth-beam A. As the latter mcreases in diameter by the winding up of the cloth,tl1e movement of the cloth-beam has to-be reduced, and this is accomplished by the aforesaid movement-that is, the continual shifting of the cam R and the consequent inward movement of the guide J and the shortening of the stroke of the pivoted arm Thus it will be seen that as the winding up of the cloth on the cloth-beam proceeds the movement of the latter becomes slower to compensate for the increasing diameter of the cloth-beam.

By making the plate V adjustable on the face of the gear-wheel C more or less movement can be given to the ratchet-wheel T, according to the thickness of the threads woven into the fabric.

It will further be seen that the stroke of the lever O can be regulated by adjusting the friction wheel or roller Q in the slot O4 1n the upper end of the said lever O, and the throw of the bell-crank lever N can be regulated by adjusting said bell-crank lever on the lower end of the lever O. A further adjustment of the device can be made by the lug K, held adjustably on the front end of the guide J. Thus before the operator starts up the loom he can adjust the several parts so as to conform to the distance between two picks in the fabric to be made.

It will further be seen that the device is very simple and durable in construction, and can be readily applied to any loom now in existence.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a compensating attachment for clothbeams, the combination, with a spiral cam and means for actuating the same from the cloth-beam, of a pivoted arm controlling the movement of the cloth-beam, intermediate mechanism to connect the said pivoted arm with the cloth-beam, a guide held to slide on the said pivoted arm and operated `from the lay of the loom, and mechanism for connecting the said guide with the said spiral cam,

substantially as shown and described.

In a compensating attaclunent for clothbeams, the combination, with a guide operated from the lay of the loom, of a pivoted arm on which is held to slide the said guide, a ratchet mechanism operated from the said pivoted arm and connected by a train of gearwheels with the cloth-beam, a spiral cam, means for operating the said spiral cam from the cloth-beam, and intermediate mechanism for connecting the said cam with the said guide, substantially as shown and described.

3. In a compensating-attachment for clothbeams, the combination, with a guide operated from the lay of the loom, of a pivoted arm on which is held to slide the said guide, pawls pivoted on the said pivoted arm, a ratchet-wheel operated on by the said pawls,

'the axis of the said ratchet-wheel forming the pivot for said pivoted arm, a train of gearwheels connected with the said ratchet-wheel and operating the cloth-beam, a lever pivotally connected with the said guide and carrying a friction-roller, and a cam operating on the said friction-roller and actuated from the cloth-beam, and means for operating the Said cam from the cloth-beam, substantially as shown and described.

fl. In a compensating attachment for clothbeams, the combination, with a guide operated from the lay of the loom, of a pivoted arm en which is held to slide the said guide, pawls pivoted on the said pivoted arm, a ratchet-wheel operated on by the said pawls, the axis of the said ratchet-wheel forming thc pivot for the said pivoted arm, a train of gearwheels connected with the said ratchet-wheel and operating the cloth-beam, a lever pivotally connected with the said guide and carrying a friction-roller, a cam operating on the said friction roller and actuated from the cloth-beam, a ratchet-wheel held on the face of the said cam, and a pin adapted to engage said ratchet-wheel and held on a plateadjustably secured to the gear-wheel on the shaf t of the cloth-beam, substantially as shown and described.
