SlLK-REELING MACHINERY.

BPE'JIEIGATION forming part of Letters Patent No. 334,618,'dated January 19, 1886.

Application filed April 23, 1884.

May 9,1882, No. 147,624, deposited February 25, 1882; in Austria May17, 1882, No. 10,629, deposited March 28, 1882, and in German Empire March 28, 1882, No. 19,885, and in my corresponding United States application filed April 25, 1884, No. 129,196, an automatic silkreeling machine is shown and described, in

which two circuit-closing levers are employed, one operated by the breaking of the thread and controlling the stop mechanism, and the other operated by the variations in the strength of the thread and controlling the filament-supplying devices. The circuit-closing levervof the filament-supplying devices is also operated by the breaking of the thread in such machine, and hence when a thread breaks said lever closes its electric circuit and puts in operation the filament-supplying devices at a time when not needed, thereby causing waste of cocoon filaments, clogging of the machine, and consequent loss of time in placing the machine in running order again.

The object of my present invention is to prevent the filamentsupplying devices being brought into operation by the breaking of the running thread, and also in starting the machine to allow the reel to be revolved and the proper stress to be brought by the thread upon the regulating-lever of the filament-supplying devices, and also upon the lever that operates the stop-motion devices to bring said levers into their normal position before the main circuit closing and opening spring is brought upon its contact. These results I accomplish by a combination of mechanism, electrical devices, and circuits arranged and operating as hereinafter set forth.

I In the drawings, Figure 1 is a side elevation, partly in section, of a portion of the silkreeling machine. Fig. 2 is a diagram representing the devices in and connections of the electric circuit. Fig. 3 is a side view,in larger size, of the toggle-lever and parts employed Serial No. 129,021. (No model.)

therewith. Fig. 4 is a plan of the parts shown in Fig. 3. Fig. 5 is an elevation of the adjusting-fork, and Fig. 6 is a side elevation, partly in section, of the silk-reeling machine complete.

a is the main shaft of the machine, which shaft is to be revolved continuously by suitable power. Upon this shaft n is a friction wheel, a, which revolves the wheel b,and reel B when the wheel b is brought down into contact with wheel a. The reel B and wheel 12 are upon a shaft supported in a hinged frame, 0 and when the outer end of this frame is lifted, as hereinafter explained, the reel B and wheel I) are also lifted, and the wheel 12 is brought into contact with the brake-block b and the revolution of the reel stopped. The brake-block b is securely fastened to the portion I) of the frame A.

D is the feeding-drum of the machine, and this is upon a shaft supported by the standard S and said drum is revolved by means of the endless cord d, that receives its motion from a pulley, c, on the shaft of the reel. This endless cord d passes around a pulley, 6 upon the shaft of the drum D, and said belt is guided by the rollers e, e, e", and e.

i is the filament-attaching device, consisting of a hollow cylinder having one or more hooks upon its exterior. This cylinderiissupported by an arm extending from the standard 8 and it is revolved by the belt d. The cocoon filaments from cocoons in the water-vessel E are gathered together to form a thread and passed through the filament attaching device and thence to the feeding-drum D, around which the thread is passed one or more times. From the drum D the thread is led around a small roller upon the lever F, then around the roller f which is on a fixed support, then around a small roller upon the lever F, and thence to the reel B, upon which it is wound.

F is the lever which closes an electrical cirare so proportioned that the reel B is revolved at a greater surface-speed than that of the These levers F F are feedingdrum D; hence there is a constant strain upon the thread between drum D and reel B, which causes an elongation of the thread. Vhen the thread is of the standard size and strength,the pull of the thread keeps the lever F away from its contact-point 0'; but if the thread becomes smaller, and consequently weaker, then the pull upon said lever F lessens, and said lever makes contact with the point 0' and closes an electric circuit, which brings into action devices that revolve the cocoouholder H, which latter, when turned, brings into position a cocoon filament so that it is taken by a hook of the filament-attaching device 1' and added to the running thread. Thisadditional filament is generally sufficient to bring the thread to the standard size and strength, and the pull of the strengthened thread is now sufficient to move the lever F and break the electric circuit at 0' and further rotation ofthe cocoon-holder is prevented until the circuit is again closed at c".

The parts thus far described are substantially the same as corresponding parts in my said application No. 129,196 and the mechanical means next described for rotating the cocoon-holder are also the same as those shown and described in said application.

J is a shaft revolved continuously bya belt, at, passing over pulleys upon the shafts n and J, and these pulleys and belt are shown by dotted lines in Fig. 6.

Z is a ratchet-wheel firmly secured to the shaft J, and 0 is a case loose upon said shaft and having a cam, q, affixed to it, as indicated in dotted lines in Fig. 6.

p is a pawl pivoted to said case, and I is ,a lever operated by the cam q. The chain 25 is connected at one end to the lever I, and the other end of said chain is connected to a slide, t, which carries a pawl, 15*. A spring, T, tends to draw the slide and chain, so as to keep the lever I against the cam q, and also to keep the pawl t in the teeth of the ratchet-wheel x, which latter is upon the shaftN of the cocoonholder H. IVhenever the lever F makes contact with 0 in consequence of the weakening of the thread, an electric circuit is closed to the magnet G, which latter attracts its armature r and releases the lever S. \Vhenthe lever S is latched, one of its ends is held in a notch in the armature r, and the other end of said lever presses upon the tail end ot'th c pawl 12, and keeps said pawl from the teeth of the wheel Z. As soon as the lever S is released,as aforesaid, the spring 10* forces the pawlp into the teeth of wheel l, and the case, pawl, and cam revolve with the shaft J. During the revolution of said case, pawl, and cam the spring T draws the lever I toward the shaft J, by means of the slide t and chain t, and the slide during its movement causes the pawl t to turn the ratchet-wheel 00 one tooth, and thereby turn the shaft Nand eocoon-holderH sufiiciently to bring a cocoon filament into' position to be taken by one of the hooks of the cylinder 2', and be added to the running thread,

as before set forth. During the revolution of the case 0 and its parts the lever S is caused to become latched by the spring 20, and just before said case completes its revolution the pawl 1) runs under the tail of the lever S, which forces the pawl p out of the teeth of ratchet Z, disconnecting the case 0 from the shaft J, and at the same time the camq moves the lever I, chain it, and slide t, and bringsthe pawl 21 back, ready to turn the ratchet-wheel 00 another tooth, when the electro-magnet G is again energized. These parts and their mode of operation being fully set forth in my said application No. 129,196, do not require further description herein.

I will now describe how my present improvements are applied to the silk-reeling machine above set forth.

D is the electro-magnet that brings into action the devices that stop the reel when a thread breaks. This electro-magnet is supported upon a cross-piece. D*, on the upper part of the frame D", which latter rises from the table that holds the water-basin E.

L is a lever pivoted upon said cross-piece D, and its outer end is received within a notch or detent in the armature it when the reel B is revolving. One end of a wire, g, is connected to said lever L, and the other end of said wire is secured to a lever, c, that is pivoted in a support upon the top of the frame A.

d" is a connection from the reel-frame c to the lever c, and fis a spring that moves the lever e and brings the wheel 1) into contact with the brake-block 1) whenever the lever L is released from the armature k.

G is a projection, of insulating material, secured to the under side of the lever L, and A is a circuit closing and opening spring which is kept in contact with a metallic plate, 13, by the projection 0 when the lever L is in the position shown by full lines in Figs. 2, 3, and 6. The spring A and the metallic plate B are upon the cross-piece D, and this latter is of insulating material, or else the spring A and plate B should be insulated from each other. Vhen the running thread breaks, the levers F F swing upon their pivots and make contact at c 0', respectively, and the electro-magnets D and G are both energized. The circuit of magnet D is from battery B by

wires

1 and 6, point 0, lever F, wire 5, magnet D wire 4, plate B, spring A, and wire 3 back to battery, and the circuit of magnet G is from battery B by

wires

1,6, and 7, magnet G. wire 8, point e", lever F, wire 9, plate B, spring A, and wire 3 back to battery. As soon as the armature k is attracted by its magnet the lever L is released and thrown upward by the spring A, and the contact of spring A and plate B broken, opening the circuit of both magnets G and D", and the lever L and spring A assume the positions shown by dotted lines in Fig. 3. At the same time the spring f swings the lever c, which latter, through the connection (1, lifts the reel-frame, and thereby separates the wheel I) from wheel a, and brings wheel 12 into contact with the brake-block b and the reel B ceases to revolve. If the electro-magnet G become sufficiently energized to attract its armature before spring A separates from plate B, the cocoon-holder 1s revolved and a cocoon filament is brought into position to be taken by one of the hooks of the cylinder z; but said cocoon-holder will not receive any further rotation, because the circuit to the electro-magnet G is broken as soon as spring A separates from plate B. In starting the reeling-machine again after the injury to the thread has been mended, the op erator first draws slowly upon the cord and handle H, (shown in Fig. 3,) and pulls down the lever L sufficiently for the latter to move the lever 6 through the cord 9 to allow the reel-frame to drop and bring the wheel 1) into contact with wheel a, and thereby set the reel in motion. This brings the proper strain upon the thread to bring the levers F F into their proper normal position. The operator now completes the movement of handle H which brings the lever L to the position shown by full lines in Fig. 3, latching the lever L with armature 7c and bringing spring A into con tact with plate B, and the parts are now in position to be operated either by the breaking ofa thread or by variations in the size and strength of the thread.

In order to vary the leverage or strain of the lever L upon the armature k, I make use of a forked guide, w, for the wire 9. This guide is slot-ted for the clamping-screw w, by which it is secured to the frame D after said guide has been adjusted in position. The wire 9 being jointed to the lever L and passing over the guide w, the parts act like atoggle-jointin drawing upon the wire 9. When the guide to is raised, the pull of the wire 9 causes more pressure and friction of the lever L against the detentof the armature k. WVhen the guide is lowered, the wire 9 is more nearly parallel with the lever L, and the pressure and friction of lever L on armature k are lessened. By this adjustment I am able to provide asimple means by which greater or less magnetic energy will be required to unlatch the armature is for disengaging the lever L and allowing the spring-f to lift the reel-frame and reel. When the lever F makes contact with point 0*", in consequence of the thread falling below the standard size and strength, the current takes the route before set forth.viz., from battery .13 by

wires

1,, 6, and 7, magnet G, wire 8, lever F, wire 9, plate B, spring A, and wire 3 back to batteryand the electromagnet G is energized and the cocoon-holder H, revolved as before set forth, and a filament or filaments added to the running thread until said thread is brought to the desired size and strength, as previously explained. It is to be understood that the lever F is so balanced that it is not influenced sufficiently by except when the thread is broken or becomes very weak, in consequence -of failure to add cocoon filaments to the running thread after lever F had closed its circuit at 0 I claim as my invention- 1.
