IMPROVEMENT IN STOP-MOTION FOR WARPING MAGHINL digi Srigctnlt rtwrrt tu in tips glctrrs lntnit mit mating peut tf tige samt TO ALL WHOM IT MAY CONCERN:

Be it known that I, L. V. RICHMOND, of Brainerd, in the county of Rensselaer, and State of New York, have invented a new and Improved Stop-Motion for Wurping Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art tc make and use the same, reference being had to the accompanying drawings, forming part of this specication.

The object of this invention consists in the application of a stop-motion to warping machines of that class in which the yarn is wound around a vertical polygonal rcel. Stop-motions to these machines have never yct been brought into use, although they Vhave already been applied to warping machines'of that class in which the yarn is wound around a horizontal drum. To this latter kind of machines my invention will be a valuable improvement.

My invention consists in the construction and arrangement, within theA sliding-frame on which the heck is arranged, or to an independent stationary box or frame, cf a horizontal cylinder, which is provided with four or more or less flanges, which are secured at equal distances from each other along the outside of said cylinder, each flange extending from one end to the other of the cylinder. The latter is connected by a clutch to another horizontal shaft, which receives its revolving motion from a pulley or cog-wheel, and imparts the same to the cylinder by means of the said clutch. The shaft on which the latter is secured slides in its journals, and, when the cylinder is stopped by some obstacle which comes in contact with one of its flanges, the clutch-shaft, which is revolved continually, is disengaged from the cylinder by means of the said sliding motion, and thereby operating an arrangement whereby the driving-belt isA transferred to the loose pulley, thus stopping the machine. The threads of the yarn pass each through three wire loops, which are held upon the said sliding-frame, or upon the independent box. The central row of these loops consists o" flattened steel drop-wires, which are borne up by the tension of the yarn, and which drop instantaneously as soon as the thread breaks. As they are arranged immediately above theaforesaid flanged cylinder, the wire drops down as soon as a thread breaks, and thereby immediately stops the machine. p

This motion is so very simple and works so perfect and easy, not occasioning any more friction to the yarn, and not being very expensive, that it will be a great improvement, especially to the warping machines with vertical reels. A

The device can be applied to old machines as well as to new ones, without materially changing any of the working parts of the same. To the warping machines with horizontal drums this device will also be very applicable, as it is not, in my opinion, nearly as complicated and apt to get out of order as the stop-rnotion which is now used thereon.

In the annexed drawings my invention is completely illustrated- Figure 1, sheetl, being a side elevation, partly in section, of a warping machine, which .is provided with vertical reel, my device being'attached to the sliding-frame.

Figure 2, sheet 1, is a plan or top view of 4the same.

Figure 3, sheet 1, is a side elevation of the sliding-frame and post on which it moves,` viewed from the side opposite to g. 1.

Figure 4, sheet 1, is a horizontal sectional view of the sliding-box, the piane of section being indicated by the line x, iig. 1.- f

Figure 5, sheet 1, is a similar view as iig. 4, the parts being in a different position.

Figure 6, sheet 2, is a vertical longitudinal section of the stationary apparatus, taken on the line y, lig. 7.

Figure 7, sheet 2, is a plan or top view of the said stationary apparatus, the covering-plate and drop-wires being removed.

Similar letters of reference indicate like parts.

A. is the'vertical revolving-reel, which is mounted upon the vertical axis Af It receives its motion from the band a, which passes around the reel A and around a pulley, Z, on the vertical shaft B. The vertical shaft B receives its motion by the belt c from the driving pulley C, which belt c passes around the pulleys ol or d on the shaft B, as seen in tig. 1. The lower pulley d is fixed on the shaft, while the upper pulley d turns loose on the same. The upper end of th'3 shaft B runs in a journal which is secured to a cross-timber, D, which is-supported by an upright post, E, which is shown in figs. 3, 4, and 5. On this upright slides a weight or block, F, which is supported by a rope, e, which is attached to the weight, passes over a pulley, e', and is wound around the uppcr ond of the shaft A', as seen in fig. 1. To the weight F is secured a horizontal bai-, f, which is connected with a box, G, as seen in figs. 1, 4, and Thus the box moves up and down with the weightF, according to the motion of the rcel, whereby the rope 'e is either lengt-hened or shortened. v

The yarn, which is wound around bobbins orspoolsg which are secured to a bobbin-frame, g', and which yarn is shown by red lines in the drawings, is guided on its way to the reel A under or over a bar, z, and through hooks or loops on the wires z' and j, all of which are arranged in the box G. Instead of the bar L, a. series of wires, which are provided with' loops, may be arranged, while another bar may be substituted for the wires j. The threads are placed, as` described, through the loops on the wires, or under the bars L and j, and also through the loops on the flat-tened steel wires z'. These latter are drop-wires, which are held up by the tension of the yarn passing through the loops on the wires h andy'. The wires z' are made of fiattencd steel, and are provided with a hook at their upper end.- They hang in lslots or holes in the cover of the box G, and their lower end is also provided with a hoolr, or rather it is bent once at a right angle, as seen more particularly in fig. G. Exactly below the row of drop-wires z' is arranged in the box G a horizontal cylinder or shaft, H, which is provided with four (more or less) flanges ZL', extending from end to end of the said cylinder. Near the end of the cylinder is arranged a clutch, K, with rounded'tapering edges, (see figs. Lland 5,) which engages a sliding-clutch, Z, which moves loosely on the end of the shaft H, as seen in the drawings. This sliding-clutch Zis moved by a pinion, m, on the horizontal shaft m', meshinginto a cog, Z, on the clutch Z, the shaft m being mounted on bearings outside of the box G.

A pin, m, which is provided with a forked end, mm, as seen in figs. 2, 4, and 5, is pressed gentlyby a spring or cord, n, which will be hereinafter described, against the sliding pinion and clutch Z Zi', and thereby engages the clutch Z with the clutch k of the cylinder H, so that the latter is revolved as the shaft m" receives motion. Y

The cord o gives motion to the shaft m as it passes overa pulley, ZY, on the shaft B, and over the pulley o on shaft m. The cord o is sustained and guided by friction-rollers p 1vp" and y* in such a manner that it will not he stretched or slackened by the up-anddown motion of the box G, but will always revolve the shaft m uniformly. A cord, n, which is secured to the floor on which the machine stands by a staple, q, and which passes in front of the fork m" and behind the pins q between which the fork is arranged, (sec lig, 3,) is secured at its upper end to a fine spring, r, (sce Fig. 2.) The end of the spring r holds a latch, s, down, which latch, as

vsoon as released from the spring r, releases a bolt. t, which is pulled back by a spiral spring, u, and is connected by a cord, r, to a fork or light frame, u'. This fra-me w is arranged on the belt e, and as soon as the bolt t is pulled back by the spring u', and with it the cord e, the frame w is raised and raises also the belt c, thereby placing it upon the loose pulley d and stopping the motion of the machine. A downward extension, w/, on the frame w serves as a handle to put the machine in motion'again, as by pulling on the same the belt c will be replaced upon the pulley d. Thus, as soon as any one thread breaks, the hooked drop-wire z', through the eye or loop of which it passes, drops, and engaging one of the flanges Zi on the cylinder H prevents the latter from moving. Thereby the rounded off-clutchl will move oli, as shown insfig. 5, (as it cannot stop its motion,) and will press the fork m" against the cord n, thereby releasing the latch s from the spring r, and thus stopping the motion of the machine.

This same arrangement can he applied to the warping machines which are provided with horizontal drums in place o f the 'vertical reel A. Tile arrangement of mechanism employed in a machine in which the bon that carries the square eyes is stationary is illustrated in figs. 6 and Y. In this the reel A" is rotated by means of .a band (not shown) which passes over the pulley a on the vertical 'axle B. The latter receives motion by means of the bevel gear-wheels y and y form a horizontal shaft, A\, which is hung on cross-bars L, which connect the supporting-posts M of the stationary box G. The posts M are firmly secured to the floor, and the box G is by them held so that it cannot more at all. The horizontal shaft X is driven by a belt, N, which passes over the driving-pulley, (not shown,) and over the pulley [i or d on the shaft X. The latter pulley turns loose on the shaft. I

The bevel geur-wheels yand y are secured to a slotted tube, X', which slides on the shaft X, and 'is revolved with the shaft by means of a pin, Z. A sliding-bar, O, which extends from one end to the other of the box G, and which is provided with a bifurcatcd lever, P, working in a clutch, P', on thb tube X, serves to direct the motion of` the shaft X and its appendages. v

All the other parts of the stopping apparatus are exactly like those in the sliding-box G, with the exception that allthe parts are contained in the box,'while in the other device the cord yn formed a connection between the box G and the stoppingapparatus on the bar D.

The cylinder H is in this modification provided with flanges h', and the clutch operates in the manner already described, the sliding-clutch Zbeing revolved by a pinion, m, on the shaft m', the lutter receiving motion from l the shaft X by a band, o. The sliding-clutch Z, when pressed back by the stopping of the cylinder H, operates a slotted sliding-plate, z', which is by a spiral spring, z, pressed against the sliding-clutch, being provided with an upright arm, 2*. When the plate z is moved it operates on the spring r, which holds the latch s in place.

As soon as the springr is moved the latch s disengages the horizontal sliding-bar t, which is at one end provided with a staple, w, whereby the belt N is held, so that when the bar t is disengaged from the latch s it will he pulled forward bythe spiral spring u, and will thereby shift the belt N upon the loose pulley (Z, thus stopping the machine.

In some cases it is necessary to omit some of the threads, when they will be cut oft` outside of the slidingframe, z'. e., between the latter and the reel. The threads are then weighted to prevent the hooks 1T from dropA casse 3 ping. And to provide against a possible stopping of the machine by the dropping oi' those hooks, whichl are not used, I use a metal plate, R, which I slide into one end of the box Gr G as far as necessary, so as to hold any required number of-the hooks z', and prevent them from dropping upon the cylinder II. This plate R' is clearly shown in iig. 6.

What `I claim as new, and desireto secure by Letters Patent, is

1. I claim the construction and arrangement in the sliding-box G of the cylinder H, with ilanges L, upon which the hooks 'i rest, iu such a manner that their eyes shall be above the upper plate ofthe said box, whereby the threads are easily adjusted, as herein shown and described.

' 2. I claim the sliding-box G, provided `with the anged shaft H, having the fixed clutch K and sliding coggedclutch Z Z', in combination with the pinion m, horizontal shaft m', and pulley ov', arranged and operated by means of the band a from the shaft B, substantiallyas and for the purpose herein shown and described 3. I claim the stationary box G', with its appendages,- consisting of the flanged cylinder H, sliding-clutch Z, having arm 2*, sliding-plate springs z and 1', latch s, horizontal sliding-bar t, having staple@ and spring n, operated from the shaft X by means of the cord o, substantiallyas herein set forth.

4. I claim the plate R, for sustaining the drop-wires t', and operating substantially as herein shown,

and

described.

5. I claim the c ord n, for the purpose of transferring the motion from the forked sliding-bar m to the spring 1', substantially as herein shown and described..

6. I claim the combination of the forked bar m" with the pinsq'q an d cord n, substantially as and for the purpose herein shown and described.
