ADOLF FABER DU F AUR, OF NEVARK, NEIV JERSEY, ASSIGNOR TO ROBERT ATIIERTON, OF PATERSON, NE? JERSEY.

MULTIPLIER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 572,250, dated December 1, 1896.

Application filed August 5, 1896.

To all whom, it may concern:

Be it known that I, ADOLF FABER DU FAUR, a citizen of the United States, residing in Newark, county of Essex, and State of New J ersey, have invented certain new and useful Improvements in Multipliers for Looms and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification The object of my present invention is to provide a multiplier for box-looms, by means of which certain picks can be repeated without the use of a long and cumbersome pate tern-chain, of simple, strong, and durable construction and reliable in operation.

The invention consists in the improved multiplier, its actuating and controlling mechanism, and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described and finally embodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a side elevation of my improved multiplier arranged on a portion of a loom-frame of ordinary construction; Fig. 2, a rear elevation thereof, the pattern and the auxiliary chain being removed; Fig. 3, a detail view of the sprocket-wheel actuating and controlling mechanism; and Figs. 4 and 5 detail views of the sprocket-wheels and of the pattern and auxiliary chains, respectively, carried thereby.

In said drawings, (4 represents a portion of a loom-frame, and a a a bracket-frame secured thereto, which latter furnishes the bearings for the shaft 0, which is arranged parallel to the main driving-shaft I), mounted in the loom-frame a. On the shaft 0 is securely mounted a sleeve e, having integral therewith (or fixed thereon in any desired manner) the sprocketwheel c and ratchet-wheel e and also the wheel 6, by means of which the shaft c may be rotated by hand. On

said shaft 0 is also loosely mounted a sleeve a having integral therewith (or fixed thereon in any desired manner) the s procket-wheel Serial No. 601,694. (No model.)

e, the ratchet-wheel 0 and the hand-wheel 6 The ratchet-wheels 0 and o which have their teeth. out in opposite directions, are arranged in close proximity to each other and are separated by the sleeve 0 loosely mounted on the shaft 0 and provided with the arms 0 and c otally connected, as at 0 to the arm 0 projecting from the ring or rim 0, surrounding the eccentric c, which latter is secured on the main driving-shaft b. To the free end of the arm 0 is secured the pin 0', on which are arran ged-and on each side of the arm--the pawls c and 0 adapted to engage the teeth of their respective ratchet-wheels 0 and o (See Fig. 3.) V

In the bracket-frame a, and above and parallel to the shaft 0, is secured the rod a", from which is adjustably suspended,by means of the set-screw a the forked bracket a serving as a guide for the levers a a fulcrumed on the stub-shaft a which latter is secured in the projecting portion a of the bracket-frame a. Said levers are arranged above the sprocket-wheel e and are adapted to be operated by the balls or rolls of the pattern-chain 6 Fig. 4, as will be manifest.

On the rod a is loosely mounted the sleeve g, which is prevented from lateral motion by the collars 9 secured to said rod. Integral with the sleeve g or secured thereto in any desired manner are the depending arms g and 9 carrying the horizontally-projecting .pins and adapted to en age the pawls J g c c and 0 respectively, in a manner hereinaf ter described. The sleeve g and its depending arms 9' g are held in operative position by means of the flat spring 9, secured with one end to the projecting portion a of the bracket-frame a and provided at its other end with teeth engaging the notches Q23, arranged in lug 9 which latter projects from the sleeve 9. (See Fig. 3.) The spring g may be strengthened by the pin 9 secured with one end substantially in the center of the spring and with its other end to the rod a", all as clearly shown in Fig. 2 of the drawings.

The pattern-chain e is carried by the The free end of the arm 0 is piv- 1 IOO to and projecting from the bracket-frame a, while the auxiliary chain 6 is carried by the sprocket-wheel c and rests with its depending portion on the slide or guide f, also secured to the bracket-frame a.

On one or more of the rods of the patternchairi e is arranged a ball 6 in alinement with the depending arm g and adapted at certain intervals to engage the said arm, as afterward described. The auxiliary chain 6 is likewise provided with balls e adapted at certain intervals to engage the depending arm 9 In operation a continuous oscillating motion is imparted from the main driving-shaft through the eccentric c and arms 0 and c to the arm 0, arranged on the sleeve 0 and carrying the pawls c and a". The pawl c is normally held out of engagement with the ratchet-wheel o by means of the pin 9 and thus prevents rotation of the sleeve 8 and the sprocket-wheel (carrying the auxiliary chain 6 connected therewith. The pawl 0 whenever the arm c is oscillated from right to left, Fig. 3, moves the ratchet-Wheel 0 and thus the pattern-chain 6 The patternballs will thus come under and raise or operate the respective levers a or a, thereby actuating the respective parts of the shuttlechanging mechanism to bring the required box in position to throw its shuttle. The pattern-chain continues to revolve until one box is required for more than one pick, that is to say, one of the levers a a is to be lifted and held in its raised position until the necessary picks or throws from the shuttle of the box, actuated from said lever, have been accomplished. At the required moment the ball 6 of the pattern-chain comes in contact with and throws or swings the depending arm'g, carrying the pin 9 outward until the said pin, after engaging the pawl 0 has thrown the latter out of engagement with the ratchet-wheel 0 Simultaneously the depending arm g carrying the pin g is thrown or swung inward, thus clearing the pawl c and allowing the latter to engage the teeth of the ratchet-wheel o The ratchetwheel 0 is thus rotated in a direction opposite to the direction of the ratchet-wheel 0 and as it is in fixed connection with the sprocket-wheel c the auxiliary chain 6 9 is revolved or operated. Said auxiliary chain continues to revolve until the respective pick has been repeated the required number of times. At that pick the ball e comes into contact with and throws or swings the depending arm g carrying the pin g, outward until the said pin has thrown the pawl 0 out of engagement with the ratchet-wheel 0 thus stopping the rotation of the latter. Simultaneously the depending arm g, carrying the pin 9 is thrown inward, thus releasing the pawl c which latter again engages the teeth of the ratchet-wheel 0 and rotates the same. The depending arms g and g are held in their respective positions by the flat spring g, as heretofore described. It will thus be seen that when the ball e of auxiliary chain 6 engages the depending arm g the said auxiliary chain is at rest, while the patternchain is rotated. On the other hand, when the ball 6 of pattern-chain e engages the depending arm g the said pattern-chain is stopped in rotation and the auxiliary chain started in a manner heretofore described.

To remedy defective picks, the sprocketwheels 6 and (2 may be operated by hand forward and backward by means of the wheels 6 and a, respectively, as will be manifest.
