IMPROVEMENT IN SPlNNiNG=EVlACHINES.

Specication forming part of Letters Patent No. 123,221, dated January 30, 1872.

SPECIFICATION.

I, GEORGE BERNHARDT, of Radcliffe, in the county of Lancaster, in the Kingdom oi' Great Britain and Ireland, have invented Improvements in Spinning-Machines, of which the following is a speciiication.

Nature and Object of the Invention.

The object of my improvements in spinning- Inachines is to modify and arrange and make additions to them, so that all the full bobbins of a frame or machine may be simultaneously removed from the spindles and replaced by empty bobbins in a very short time by means of. mechanism operated upon by hand at one end of the machine, and thereby economising time a-nd labor and increasing production; and my invention consists in the combinations, arrangements, devices, and mode of action hereinafter described for attaining' the above-named object.

.Description cf the Accompanying Drawing.

Figure l, Sheet No. l, is a cross-sectional elevation of so much of a spinning-frame as will be necessary for eXplainin g myinvention; and Fig. 2, Sheet No. 2, is a front elevation of the same, showing only one spindle and part of the front covering-plate h supposed broken away. Fig. 3, Sheet l, is a detached side view, and Fig. 4, Sheet l, an end view of the bobbins employed.

The improvements are illustrated as applied to a ring and traveler sl'iinning-frame, more particularly intended for twisting threads, and commonly termed doubling frames A, the two end frames; Al, spindle footstep rails; A2, upper spindle-bearing rails; A3, roller beams; n, draft or other rollers; b, tin drum or roller for driving the spindles c and l is the ring or copping-rail. All the above-mentioned parts are ordinary. e are shafts for actuating the coppin g orring-rail, these shafts having toothed wheels e1 upon them, which gear with rackteeth in bars e? that slide vertically through bearings in the upper and lower spindle-rails A1 and A2 and the ring or copping-rails are secured to the upper ends of the said bars e2. The shafts e receive oscillatory movement to distribute the thread from the ordinary mechanism usually employed, which acts upon the toothed wheels e3, which are loose upon the shafts. but when the machine is spinning these wheels are made fast to the shafts by clutches e4, that slide on a iixed key. The clutches are acted upon by clutch-levers e5, and the clutches for both sides of the frame are connected so as to be simultaneously acted upon by securing both clutch-levers upon a cross-shaft, es, carried by brackets secured to the end framing. The two shafts c are geared together a-t the end of the frame by means of a toothed wheel, e", on each of the shafts e, and two intermediate wheels, e8 and e9, and one of the latter wheels e8 is in gear with a pinion,fl, on the boss of a hand-wheel, f, loose on the end of' pitch-lines of the toothed wheels last referred to are shown in Fig. l in peculiar dotted line. hen the machine is spinning the hand-wheel fis free to oscillate to and fro with the movement of the copping or ring-rail d. b1 is a hand-wheel, fast on the end of the tin-roller shaft, for turning the tin-drum when required. g ls\a rail passing from end to end of the machine, and through this rail there is a hole for each spindle just large enough to pass over the brad 7 cl upon each spindle having the pins in it that drive the bobbin, but smaller than the head of the bobbin. This rail serves to lift the bobbins when doiiing and rests when the machine is spinning upon the upper spindle-rail. The lifting-rail g is mounted upon the upper ends of vertical bars gl sliding in bearings in the spindle-rails, these bars having racleteeth, each rack gearing with awheel, g2, loose upon the shaft e, so that they do not move with the shafts when spinning, but when these shafts oscillate beyond the extent of movement required in spinning a pin in a boss, g3, fast on the shaft e, comes against a pin 011 the face of the wheel, and thus causes the rail gto be lifted. Each of the wheels g2 also gears with a rackbar, h1, sliding vertically on suitable guides secured to the spindle-rails. The upper end of each of these rack-bars has a bracket, h2, secured to it, to which the thin plate h, of metal, is attached. These plates are for the purpose of covering and uncovering the empty bob bins and mechanism for carrying the same, hereinafter described. The covering-plate h is shown in the position it occupies when the the sha-ft of the tin-drum or roller b. The

machine is spinning on the left of Fig. l, and in the position it occupies when dottlng on the right of the same figure. 7c is a shaft passing from end to end ofthe frame in suitable bearings in the frame. Upon this shaft, at suitable intervals, disks k1 are keyed, each having two crank-pins k2, to each of which one end of a link, k3, is jointed, the other end being jointed to a rod, k1, sliding in a bearing secured to the under side of the roller-beam. To the ends of the slide-rods (the number being according to the length of the frame) a rail, 7J, is secured, which passes from end to end of the frame 5 and to the rail a tube, k7, is secured to come opposite to each spindle. These tubes are made of metal, and are open in front, except just at their upper ends, the opening being sufficient to allow the barrel of the bobbin to pass through when slightly lowered, so that the head of the bobbin will pass below the bottom of the tube. The empty bobbins are passed into each tube while the machine is spinning' through a hole in the roller-beam, which is made opposite to each tube, and the bobbin rests upon a table formed by a plate, las, (one on each side of the frame,) passing from end to end of the machine and carried from the roller-beam by brackets kg. The vertical part of the table-plate also serves as a cover, and in it slots are formed for the brackets h2 to pass through that carry the moving covering-plate h. There is a handle, k1", upon the end of the shaft k, by partly rotating' which until it comes against a stop-pin, kx, in the frame the empty bobbin-rails k5 on both sides are simultaneously pushed outward until the center of the bobbins come over the ends of the spindles.

I will now describe the mode of dofling by the mechanism. WVhen the bobbins are full the copping mechanism is thrown out of gear with the sha-tts by moving the clutch-levershaft e5, and then the copping or ring-rails (l are lowered by the hand-wheelj', while a small portion of thread is wound upon the lower part of the brad7 01. Then the machine is stopped. The hand-wheelf is then turned back, and the ring-rail Z is lifted to the position shown on the right of Fig. l, the hinged-wire curl or guide-board l being lifted into the position shown. The same movement which lifts the ring or copping-rail also carries the liftingrail g to the position shown on the right of Fig. l, where its upper surface is just level with the empty-bobbin table-plate 7c8 and just above the tops of the spindles c, and the same movement of the hand-wheel also brings the coveringplate h into the position shown on the right of Fig. l. The handle 7610 is now moved till it comes against the pin kx, and the empty bobbins are by this movement brought over the spindles, as shown, on the right of Fig. l; then the lifting-rail gis lowered slightly by the handwheel f' to bring the heads of the bobbins clear of the bottom of the tubes k7, and the handle k1" is then turned back to bring the tube-rail 7.5 back into the position shown on the left of Fig. l. The empty bobbin-rail g and ring-rail d are then lowered and the clutches e4 are brought into gear again, and. this completes the operation, which takes from fifteen to thirty seconds.

The collar upon the brad c1 is roughly milled on its edge, and the lower head of each bobbin is notched, as shown by the detached views, Figs. 3 and 4. This ronghening ofthe collar and notching of the bobbin is important, as it prevents the bobbin from turning and the thread from uncoiling from the bobbin when lifted, and consequently when the full bobbins are lifted the threads are broken with certainty between each bobbin, and that part wound upon the lower part of the brad, leaving' the thread between the traveler and lower part ofthe brad ready to wind upon the bobbin when the frame begins to work. full bobbins are pushed from the lifting-rail g by the empty bobbin-tubes L5, when they collie forward, and they fall into any suitable receptacles placed on each side of the frame to catch them. I employ a receptacle formed by two frames jointed together to fold like a campstool, which can be easily carried from one frame to another, as required.

When dofling it is an advantage to gear the rollers a on both sides together, so that they can be turned forward slightly (about one-third of a revolution of the front roller) to give slackness to the threads when doiing, which prevents breakage when the empty bobbins come forward.

Ola/5ms.

1. The ring-rail d and the dofng-rail g, operated independently of each other from the same shaft e, through the medium of the racks and pinions, or their equivalents, substantially as described.

2. The combination of the lifting-rail g and sliding-plate lb, as set forth.

3. The combination, with the spindles, of a stationary platform, kg, secured to the frame of the machine, for the reception of the bobbins preparatory to transferring .them to the spindles, as described.

4. The combination of the ring-rail d, liftingrailg, platform la, a-nd sliding tube or case k7, all operating together, substantially as described. l

5. The combination, with the brad c1, of the roughened collar, arranged to insure the simultaneous breaking ot' the threads between the bobbins and the brads by the eleva-tion of the lifting-rail g, substantially as described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
