SPECIFICATION forming part of Letters Patent No. 723,624, dated March 24, 1903.

Application filed June 7, 1902. Serial No. 110,591. '(No model.)

T0 at whdWt it may concern:

Be it known that I, GRANT SIPP, a citizen of theUnited States, residing in Paterson, in the county of Pass'aic and State of New Jersey, have invented certain new and useful Improvements in Reeling-Machines; 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 appertai'ns to make and use the same, ref erence being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specifica-' tion.

This invention relates to machines for reeling silk. It is customary in these machines to employ the friction-drive in the. mechanism for transmitting rotary motion to the reels, and in order to automatically stop the machine either when apredetermined amount of silk is reeled off or a break occurs in the silk various expedients have been proposed for disconnecting the members of this friction-drive.

With the object of rendering machines of this nature more positive and reliable in action, especially in so far as the above-mentioned operations of stopping are concerned, I have improved upon the same substantially as will be hereinafter described and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, Figure 1 is a front view of a portion of a reeling-machine constructed substantially in accordance with my invention. Fig. 2 is an end View of the machine, showing substantially what is seen in Fig. 1 in side elevation. Fig. 3 is a plan view of a portion of a certain rocking frame, a portion of the device whereby said rocking frame is set, and a portion of a certain part which it controls and illustrat ing how these several members are relatively arranged. Fig. 4 illustrates in side elevation the mechanism whereby the traverse-rail is reciprocated and whereby the disconnection of the members of the drive is effected upon a predetermined amount of silk being reeled off. Fig. 5 is a vertical sectional View taken on the line a; w in Fig. 4:. Fig. 6 illustrates a detail of what is seen in Fig. 4, and Fig. 7 illustrates another detail.

As is usual in machines of this nature, the

uprights is journaled a rock-shaft t.

frame consists of a series of uprights a, braced in any suitable manner. My presentmachine is constructed to accommodatetwo reels, with their various accessories, between each pair .of uprights, one at the front and the other at the back of the machine.

In one of the end uprights of the machine is journaled themain drive-shaft 1), provided with pulleys c or other equivalent means for transmitting a rotary motion to said shaft from a belt or the like. 4

d is a revoluble shaft carrying frictionwheels e,.one between every pair of uprights a. This shaft is connected with the shaft Z) by bevel-gearing f. In U-shaped bearings g in each pair of uprights a are seated the ends of the shaft h, which carries the reel 2' and the nature of whose bearings 9 permits an up-and-down movement of said shaft, which is made use, of, as is common, to effect the frictional engagement and the disengagement of a friction'wheelj, carried on said shaft h, with the friction-wheel 6. Thus is produced the usual-friction-drive.

k is a bracket which is secured to each of the uprights a. In its rear end is fulcrumed the horizontal portion Z of a lever m, whose vertical portion n is curved rearwardly and carries at its extremity a shoe 0, preferably of leather. The shoe is adapted to be moved from its rear position against a stop g on the frame into contact with the periphery of the friction-wheel j, so that since the frictionwheelj revolves in the direction indicated by the arrow in Fig. 2 the effect of its impact with friction-wheelj will be to not only brake the action of the friction-wheel and the shaft h and reel 2', which it drives, but tend to raise it, and thus effect a disconnection between said friction-wheel and the friction-wheel e in an obvious manner.

In each pair of brackets is is formed a V- shaped bearing 8, in which between each two In order to normally prevent endwise movement of the shaft in its bearings and at the same time permit this movement of the shaft for the purpose of removal thereof or adjustment, a guard to is pivoted over the opening in the bracket formed by the bearing 3. The shaft tforms the fulcrum of a frame 1:, which, as seen in Fig. 3, consists of two cross-arms w,

connected together at their ends by rods or wires x, which penetrate said cross-arms and onto which are screwed tightening-nuts 3 Since certain fallers (to be hereinafter described) are adapted to engage the wires or rods 01;, it is necessary for this and other reasons that the rods as be drawn up taut, and for this purpose a collar .2 is adjustably secured on the shaft inside of one cross-arm and has a V-shaped recess 1, in which a knife-edge 2 on the cross-arm engages. It should be remarked that the cross-arm is not fast on the shaft, but has an elongated opening 3 to receive the same, so that after one rod or wire has been adjusted the other can be drawn up tight, the one cross-arm being free (by virtue of said elongated openings 3) to 'move on its knife-edge as a fulcrum. The other cross-arm is secured rigidly on the shaft.

Near one end of the shaftt is secured a weighted arm 4. Moreover, one of the crossarms is provided with a radially-adjustable weight 5. The tendency of these weights under normal conditions is to keep the rocking frame substantially in the position illustrated in Fig. 4, where it is held slightly inclined, with its front portion uppermost, its weighted arm 4 bearing against a stop 6 on the adjacent upright; but if the forward portion of the frame is depressed sufficiently so as to throw it past its center of gravity the weights will tend to throw the frame in the other direction. The portion 1 of the lever m is therefore formed wit-h a lug 7, which overhangs the rear portion of one of the cross-arms w of the rocking frame, so that when the rocking frame is caused to tilt out of its normal or rest position it will engage the lever m, causing its shoe to be thrown forward, as above described, and effecting the disconnection of the friction-wheels e and j.

It should be remarked that a stop 8 is provided on the frame to limit the forward motion of the lever m.

9 is the traverse-rail, arranged to reciprocate in brackets 10 and carrying eyelets 11.

'The silk passes from spools or bobbins 12 around bars 13, carried by the brackets 70, and then up through the eyelets 11 onto the reel; but between the bars 13 and eyelets 11 it is engaged by the fallers 14, which consist of wires looped to form eyelets 15 and carried by two-part arms 16, which are fnlcrumed in clamps 17, secured on a rod 18, which connects the several brackets 70. These fallers afford the automatic means whereby should a thread break the mechanism above described by which the members of the friction-drive are disconnected is initially set in motion, said fallers being adapted upon the breakage of the threads to drop and engage the front portion of the frame '1; to tilt the same.

- 19 is a casing which is secured to one of the uprights, as by bolts 20, and comprises a tubular part 21. The tubular part serves as bearings for a short inclined shaft 22, vwhose lower end is provided with a crank 23, carrying an antifriction-roller 24, which engages a slotted arm 25, projecting from the traverserail. At its upper end this shaft has a bevelpinion connection 26 with the shaft h. Thus the traverse-rail is reciprocated.

The shaft 22 is provided with a worm 27,

which engages the teeth of a worm-wheel 28,

which is journaled on a shaft 2Q in the casing 19. The worm-wheel is formed with an eccentric 30, which is received by and oscillates a loop-shaped lever 31, fulcrumed at 32 in the casing. This lever carries at its upper end a gravity-actuated pawl 33, adapted to engage the teeth of a ratchet-wheel 34, journaled on the shaft 29 and formed with a cam 35. A weighted detent-pawl 36 prevents reverse action of the ratchet-wheel. The pawl 33 is made in two parts, adjnstably secured together by a slot-and-bolt connection 33, whereby adjustment of the pawls action with respect to the ratchet is secured.

37 is a lever which is fulcrumed in the easing 19, its upper end being adapted to be engaged by the cam 35, while its lower end carries adjustably secured thereto a weight 38, acting as a striker, which when the lever is swung under actuation ofthe cam is adapted to engage a lug 39 on the adjacent crossarm of the frame 1) to tilt said frame.

By means of the above-described mechanism at each complete revolution of the cam 35 the lever 37 will be actuated, as already indicated, to automatically set in motion the mechanism whereby the disconnection of the members of the friction-drive is effected. Themachine can thus'be made to stop when a given amount of silli has been reeled off, and in order to adjust this I provide an arm 40, which is pivoted on the shaft 29 and is formed -with a concentric guard 41, covering the teeth of the ratchet-wheel in such manner that according to the position of said guard the pawl 33 can be kept out of engagement with the teeth oftheratchet forsuchportionofits throw as is found to be necessary in order to give the ratchet the intermittent action desired. The arm 40 is rendered adjustable by means of a spring-actuated detent 42, having a knob 43 and being adapted to engage with any of a segmental series of notches 43', formed in a suitable portion of the casing.

When the machine stops on account of a thread breaking and the consequent dropping of a faller, after the break has been repaired the parts may be reset by means of a lever 44, which is fulcrumed in the bracket and has its inner end extending over the lug 7 on lever m and turned inwardly, so as to also extend over the adjacent cross-arm w of the rocking frame, so that by pulling up on the outer end of the lever the lever m and the rocking frame will be pressed back, the one in engagement with its stopp and the other with its arm 4 engaging the stop 6.

In order whenever the machine stops because the mechanism which is actuative upon the reeling off of a predetermined amount of silk has set in motion the rocking frame '0 that the operator may identify this with the proper cause and also be prevented from starting the machine without appreciating that the predetermined amount of material has been reeled OH, I provide a hook-shaped detent 45, which is fulcrumed at 32 in the casing and is adapted to engage a lug 46 to hold the striker 38 opposite the lug 39 on the rocking frame. The detent 45 has a handle 47 for releasing it from the lug at the proper time. It will be noticed that normally it rests against the upper face of the lug, as shown in- Fig. 4, ready to drop into operative engagement therewith when the lever 37 has moved far enough.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
