MACHINE FOR THROWING SILK.

SPECIFICATION forming part of Letters Patent No. 364,785, dated June 14, 1887.

Application tiled October 10,1883. Renewed November 13, 1885. Again renewed November 9, 1886. Serial No. 218,416. (No model) To all whom it may concern.-

Be it known that I, JOSEPH E. TYNAN, of Paterson, in the county of Passaic and State of New Jersey, have invented an Improvement in Machines for Throwing Silk, of which the following is a specification.

In. machines for throwing silk in the doubling and spinning employed in' making the organzine warps the threads are drawn off two or more spools and brought together and twisted and wound upon a bobbin. The spools from which the threads are drawn are rotated in one direction to twist the threads, and the spool or bobbin 'on which the threads are wound is rotated in the other direction to lay the threads together and twist them as the winding progresses. J

My present invention relates to the mechanism for effecting the beforenamed-object in a more uniform and reliable manner than here tol'ore, and for stopping the parts it a thread breaks, or if the ring-traveler flies off, or if the driving-belt breaks or slips. 1

In the drawings'fFignre 1 is an elevation of the parts of a silk-throwing machine with the present improvements thereon and with the rails and beltshifter in section. Fig. 2 is a front elevation of the same. Fig.3 is a plan of the spools and friction-disks and the adjacent devices for operating the same. Fig. 4 is a sectional plan at theline xx, Fig. 1. Fig. 5 is a sectional plan at the line 1 3 of Figs. 1 and 2. Fig. 6 is a plan of the feed-roller and the pivoted beam. Fig. 7 is a detached view of the bearing for the feed-roller shaft. Fig. 8 is a section in larger size of the spindle-rail bolster, bolster-sockets, steps, and oilcups, the spindles being in elevation; and Fig.

The ring and traveler h and rail 0 are to be of ordinary character, and will be raised and lowered to lay the threads upon the .spool P by the usual mechanism.

Upon the spindle Q there is a fast pulley, T, having a disk, 0", and below it is a loose pulley, U, upon which the driving-beltw is shifted when the belt-shifter is moved to stop the spindles.

The spindles a b have upon them, respectively, the friction-disks a b, the edges of which are in contact with theedges ofthe disk dot the fast pulley T, and hence the spindles a I) receive motion from this pulley T; but they revolve in the opposite direction to the spindle Q, as indicated by the arrows in Fig. 3. The tension of the belt tends to keep the edge ofdisk c of thepulleyT in contact with the edges of friction-disks a b, and the parts are adj ustahlc, as hereinafter explained.

The bolster-sockets form oil-receptacles. The bolster-sockets BFfor the spindles a b are made with flanges 4.4, resting upon the bolster rail a, and with nuts 45 below such rail. The holes through the rail for these bolstersockets are made larger than the socket, or elongated in the direction of the spindle Q, so that the bolster-sockets B can be adjusted toward this spindle Q to regulate the contact of the edges of the friction-disks, and the parts are held by the nuts 45 and by the screws 46, (see detached plan, Fig. 9,) passing through the bolster-rail and acting against the side of each socket to press it toward the spindle Q. There are preferably two screws, 46, to each bolster-socket, to hold the parts firmly after they are adjusted.

- The bolster-socketRwhere it passes through the bolster-raila, is made with an enlargement above the rail to form the oil-cup r, and also to give a bearing upon the surface of the bolster-rail to retain the bolster and spindle in a vertical position, and the hole through the rail is larger than the bolster, so that the bolstersocket R and spindle Q may be drawn toward the spindles a b bythe action of the belt 10*, which passes around the fast pulley T to insure the necessary friction between the friction-disks a b and disk 0 of the pulley T and obtain uniformity of rotation inthe directions stated. There is a helical or spiral spring, 50, between the nut 51 of the bolster-socket Band the under side of the bolster-rail to allow the parts to yield slightly, but to maintain the bolster and spindle in a vertical position, and a pin, 52, in the bolster-socket passing into a slot in the rail, prevents the bolster-socket B revolving. I

The tubular bolsters s are similarly made for all the spindles a D Q. They are adapted to receive the lower ends of the spindles, and each one has a hemispherical bearing, i, around the central portion passing into a similarly-shaped recess at the top of the bolstersocket, and there is to be a hole, 60, Fig. 8, through said bearing 21 for oil to flow down, and a pin passing through the upper end of the bolster-socket into the hearing, as at 39, to prevent the bolster revolving. By this construction the bolster is hung by its hemispherical bearing, and this is in line, or nearly so, with the fast pulley and the frictioirc'lisks, so that the spindle and its tubular bolster may vibrate above or below the bearing 2' without varying the action of the friction-disks, the edges of the friction-disks being preferably segments of globes having the same center as the hemispherieal bearin gs.

At the lower end of the bolster for the spindle Q there is a screwstep, b. By screwing this step up or down thespiudle will be raised orlowered, and thereby the position of the friction-disk 0* with reference to the disks a I) may be adjusted with the greatest accuracy, and at the same time the pulleys T and U are kept from touching each other. The spring 1;,

that passes vertically up through the lower end of the bolster-socket, enters a hole in the lower end of the screw-step b. The screwstep slides freely down over the end of the spring, so that the weight of the parts is taken upon the bearing 6. The spring 1) tends to keep the bolster and spindle vertical; but if the bobbin is not true the spring yields and allows the bobbin and spindle to find their own axis of rotation. There are openings 61 in the lower part of the bolster to allow the oil to pass into the spindle from the bolstersocket.

Around the spindle Q, below the fast pulley T, is the loose pulley U, that has a hub that fits upon the outside of the sleeve of the bolstersocket R, and this hub revolves in the oil box or cup 1', and there is a flange, r, at the lower end of this loose pulley U,to prevent the cord or belt 10* coming into contact with the oilcup 1', and the downward flange r within the oilcup, prevents oilbeing thrown out by centrifugal action, and the flange r aids in excluding dust. There is a cylindrical dam, r within the oil-cup, having holes to permit the oil to pass through into the inner cup, and by the duct into the bolster to lubricate the spindle. This dam r prevents air-bubbles and. froth, that may form on the surface of the oil at the loose pulley, causing the oil to be displaced from the oil-cup, because the air-bubbles as they accumulate and pass over the dam are broken to a large extent by the upper edge of said dam.

The driving-belt w, drivingshaft a, tightening-pulley i, lever i weight 1', pivot 30, and jaw-block (it 011 the rail 31 are similar to thosein my application, Serial No. 108,580, filed OctoberlO, 1883; but when used as in the present application the movable weight upon the tightener causes the belt in to draw the spindle Q and its disk 0 toward the friction disks (0 I) with a uniform power, and thus uniformity of rotation is obtained.

in is the belt for revolving a spindle of the range of spindles on the opposite side of the machine. There is a standard, if, and a head or disk, o, (see Figs. 1 and 3,) above the frie tion-disks c,a",and b,but not in contact therewith, which prevents the spindle Q, or a or If being raised when a spool is pulled off. This is not claimed herein, as the same is shown in a prior application filed August 24, 1882, and allowed July 19, 1883. The drop-bar m passes through the forks or

jaws

7 and 8, that are attached to and project laterally from the respective rails, aand t, and each jaw has a pin across through it to con fine the bar in in place; but said bar in is free to slide vertically. By the removal of the pins that confine either drop-bar m in the silk-throwing machine such bar in can be taken out without stopping the machine. The drop-bar m is notched at the fork 7, and the spring 9 presses the notch of such drophar upon the said fork to hold up thedrop-bar, and upon the dropba'r mthere is the belt-shifter a and the friction-brake a to stop the rotation of the spindles. The three spindles are stopped by one brake acting upon the disk 0 of the fast pulley T. The shaft is and rollers k are rotated at the proper relative speed to the spindles,so as to regulate the twist by the extent of feed movement in proportion to the rotation of thespindles. I have shown a belt, w, as the means for communicating motion from the driving-shaft \V to the shaft Ir; but gearing might be substituted for the belt. '10 is the belt for rotating the shaft in of the range of spindles on the opposite side of the machine. This opposite range is not shown in the drawings. The fced-rollerf is upon ashaft, f that is in the slotted bearings f and f",and said rollerf rests upon the roller k. It is the most convenient to employ a shaft that ,is longer at one side of the feedroller than the other, as shown, and to prevent the feed-roller being tipped by the leverage of the long end of the shaft, and to cause the feed-rollerf to take an even bearing upon roller 7;, I make use of the adjustable forked bearing ]",Fig. 7 ,that is attached to the standardf by a slot and screw and may be raised or lowered.

At the upper end of the drop-bar m there is a frame, 10, and a beam, Z, such frame and beam being connected by the pivot 6. The beam 1 is provided at its inner end with a projecting rod and adjustable weigl1t,l,and at its long arm, Z and ashort arm, Z.-

At the outer end of the long arm Z is a finger,

Z which bears lightly upon the thread as it passes from the feed-roller f to the fixed eye or hook Z, and thence to the ring-traveler. This short arm Z is provided with a tooth or pawl, 17, and upon the feed-rollerf are the pins 18. If the thread break or theringtraveler break or fly off the ring, the beam Z swings and the front end descends, bringing the pawl 17 into the path of one of thepins 18, and said pin, striking the end of the pawl, pushes the beam endwise and moves the upper end of the drop-bar m, so as to cause it to slip off its support at the fork 7 and fall or be depressed, thus stopping the spindles by shifting the belt to theloose pulley and by the pressure of the friction-brake upon the disk 0*. .The threads that pass up from the spools a* b I go through eyes Z, and the threads that pass from the plate n upon the rail t.

down to the spool I? go through theeye Z. I

find it convenient to place these eyes upon wires or lever-arms extending out from the hinged stock Z, Fig. 5, at the back of which the lever-eyes.

Upon the drop-bar at there is asecond frame, M, to which two beams, n, are pivoted, each of which has a hook, at, at one end and an ad- "justable counterpoise, 62, at the other end, and

a tooth, n upon the body part of the beam. The rods 1 and hooks Z project horizontally The threads from the spools a and b pass up through the eyes or hooks Z Z, across over the hooks a at the ends of the beams n, beneath the rods a, that stand out from the plate a, thence they go close together up over and around the feedroller f, and out below the finger Z on the beam Z, over the hook Z", and downthrough the eye Z to the traveler and spool P, 011 which the organzine thread is wound. As the threads are drawn oil the spools a and b they are twisted in one direction by the revolution of such spools, and as the two threads after passing over the feed-roller f descend they are laid together and twisted to form a finished thread by the spindle Q rotating in the opposite direction to the spindles abiand if either of the threads break the hook at the end of the beam at, that had been beneath such thread, rises by the action of its counter-weight 62, bringing the tooth a against one of the stops 48, that project at such side of the roller is,

and the drop-bar m is pushed back and falls,

crum, and such beam Z acts below the shaft of the feedroller f to raise thesame, and thereby stop the revolution of the feed-roller f and the feed of the thread. The threads may pass up in front of a guide-bar, n Fig.1. This guidebar is partially removed in Fig. 2. It is specially to prevent a broken thread catching upon the roller is. The fingers m", that project from the drop-bar m, extend over the spools a and 1)", near one edge of each. As the spools revolve in the direction of the arrow the threads pass by the sides of these fingers, and when the spools are stopped for any of the causes mentioned these fingers descend with the drop-bar and come close to the spools and prevent the momentum or the twist causing the threads to unwind or kink. The bar m", projecting forward from the upper part of the drop-bar m, is guided in a slot in the plate a to steady such drop-bar and prevent the same partially rotating in its bearings. The fingers on may be bent into a curved form at the end, and set in a position for the threads to rub against them as the spools are revolving, which will tend to detain the thread as it unwinds in contact with the head of the spool, and apply to the samea slight and nearly-uniform tension. This tension is useful, as it prevents the weight 62 raising the hook it and tooth a so long as the tension is maintained, the thread passing over the hook 12 When the driving-band w of a spindle breaks, the twisting and winding operations are instantly stopped, and the thread, becoming slack between the receiving-bobbin and the feedroll by the continuation of the movement of the feed-roller f, the finger Z at the end of the lever Zis unsupported and descends, and the lever Z operates on the stop motion, as aforesaid, bringing the pawl 17 into action, and the feeding of the thread is instantly stopped, thereby preventing waste, because the spinning, doubling, and twisting and winding operations are all stopped when either a single or a double thread breaks or when a belt slips or breaks.

I have represented herein the entire mech anism connected with this silk-throwing ma chine, and I remark that all the novel and patentable features herein shown are my'invention; but as the. devices connected with the spindles, bolsters, and bolster-sockets form the subject of a separate application, Serial No. 131,105, the same are not hereinelaimed.

The ring-traveler h, especially in silk-machines, is light and liable to wear out; hence it is of great importance to stop the machine as soon as a traveler breaks or dies off. This is.instantly effected by the means before described, because the twisted thread becomes slack and the detector Z comes into action.

In Letters PatentNo. 326,581, granted to me September 15, 1885, (the application for which was pending at the same time as my application of which the present is a renewal,) there is a faller,lever, feed-roller, and means for re volving the roller, a frame, stop-motion rod, and spindles having tight and loose pulleys and frictioupulleys; but the claim to such is in a limited l'ornnbringing in other features in combination, which limited combination I do not herein claim.

I claim as my invention 1. The combination, with the spindles Q a If and friction-disks c a b, of a driving-belt, fast pulley T, loose pulley U, a belt-shifter, a friction-brake, a drop-bar, and mechanism, substantially as specified, to disengage the dropbar when either thread breaks, substantially as set forth.
