STOP MECHANISM FOR REELlNG-MACHINES.

SPECIFICATION forming part of Letters Patent. No. 376. 1, dated anu ry 17, 1888.

Applicatii nfiled October 27, 1856. Serial No. 217,311. (No model.)

.To an whom it may concern: 7

Be it known that 1,-JOHN E. ATWOOD, of Stonington, in the county of New London and State of Connecticut, have invented anew and useful Improvement in Stop Mechanisms for Reeling-Machines, of which the following is a specification.

My invention, although applicable in general to machines for reeling various fibrous materials, is more particularly intended for warpingmachines for reeling silk warp, and

possess great advantages when embodied in such machines. It may, for example, be advantageously employed in connection with a machine for reeling silk warp, which forms the subject of an application, Serial No. 216,388, filed October 16,1886, by Edward E. Bradley, and in the accompanying drawingsmy invention is illustrated as employed in connection with such a warping-machine.

The invention relates to that class of reeling-machines in which the driving mechanism is held operative by a'trigger or catch or latch to drive the reel, and in which the mechanism is moved into inoperative position bya spring or equivalent weight through its shipper or lever when released from the latch or catch,and in such machine the fallers or faller-wires, when allowed to drop by the breakage of a thread,

descend in the path of a bar or member hav-- ing a definite range of movement, and by blocking the movement of such bar or member cause the shipper to be released from the latch or catch and be moved by the spring or equiva lent weight to stop the machine.

In carrying out my invention the fallers are arranged in a suitable holder or frame, which comprises an abutment below which the movable member of the stop mechanism works, and when the faller is released by the break ing of a thread it falls below the abutment and into the path of the movable bar or member. The movable bar or member may be advantageously supported by pivots at its ends, so as to receive a rocking motion, and the fallers are combined in a novel and peculiar way with their holder or frame, so as to per- Init their ready detachment therefrom when desired. I also employ a rotary stop'motion shaft which carries upon it a crankarm con- V nected, by a rod or other suitable connection, with the rocking-bar of the stop mechanism, and this crank-arm is so connected with its carrier that when an unusual resistance is opposed to the movement of the rockingbar by the dropping of a faller in its path the crank will yield upon its carrier and acam provided upon the crank-arm will be projected, so that in the revolution of the stop-motion shaft it will act to throw off a latch or hook, whereby the shipper-lever or analogous device of the reel is maintained in operative condition. I also prefer to construct the stop-motion shaft in two sections arranged end to end and connected by a clutch which provides for lost motion between them. The firstsection of the stopmoti0n shaft will then be rotated synchronously with the reel, and upon the starting of the machine the reel will be rotated immediately and the first section of the stop-motion shaft will receive a partial rotation before it transmits any movement whatever to the second section of the stop-motion shaft from which the rockingbar of the stop mechanism is operated.

The invention consists in novel combinations of parts, which are hereinabove briefly referred to and are hereinafter described, and pointed'dut in the claims.

In the accompanying drawings, Figure 1 is a transverse section of such portions of a warp.- ing-machine as are necessary to illustrate my invention, and which correspond to the machine described and shown in the aforesaid application of Edward E. Bradley. Fig. 2 is avertical section of a creel from which the reel of the machine takes its threads and to which my stopmotion is applied. Fig. 3 is a transverse vertical section, upon a larger scale, ofthe holder or frame for the fallers, showing, also, thefallers arranged therein. Fig. 4 is a plan of a portion of such holder or frame with fallers arranged therein. Fig. 5 is a front elevation and partial vertical section of such portions of the machine as are necessary to illustrate my invention, a part of the machine between the ends being broken away to reduce the length of the drawings, and Fig. 6 is a horizontal section on the plane of the dotted line mm, Fig.

Similarletters of reference designate corresponding parts in all the figures.

A A designate the end standards or frames of the warping-machine, which are connected by horizontal rails or stretchers A.

B designates a reel, comprising a shaft, B, to which rotary motion is imparted by mechanism similar to that illustrated in the aforesaid application of Edward E. Bradley.

0 designates the driving-shaft of the machine, upon which is represented a pulley, O, and which has a clutch-connection, O, with the pulley, as described in the aforesaid application. Upon the inner end of the shaft 0 is represented a pinion, G which engages with a wheel, 0, and concentric with the wheel C" are two other pinions, c c, which may be connected with the wheel 0, so as to rotate in unison therewith upon astud or fixed journal. The pinion c engages a large spur-wheel or circle of spur-teeth, C upon the reel for driving it, and the pinion c engages a second pinion or wheel, 0 which is mounted upon a counter-shaft, 0 By means of pulleys 0* c and a belt, 0, or any other equivalent arrangement of gearing, rotary motion is transmitted from the counter-shaft c to the stop-motion shaft or to the first section, D, ofsaid shaft, and this stop-motion shaft will be hereinafter described more in detail.

By the movement of the driving-shaft'O lengthwise its clutch is engaged with and disengaged from the pulley O, and by disengaging said clutch from the pulley the reel B will be instantly stopped. In this example of my invention the clutch is shifted by a lever, E, which may be pivoted at its upper end, 0, and which has an arm or hook, c, engaging the shaft 0.

I will now particularly describe the portions of my stop-motion which are upon the creel, and which are shown in Figs. 2, 3, and 4.

F designates the main frame of the creel, which is provided with numerous spindles or pins f, on which are the spools f, and from these spools the threads 8 pass through a reed, f thence through fallers H, thence over a bar or rod, f, and to the reel B. The fallers and their arrangement in the holder or frame II, in which they are supported and guided, are best shown in Figs. 3 and 4. The holder or frame H consists of a bar or beam, which may be of metal, and has at the top a laterally-extending flange, 71, and nearer its lower edge a second flange or rib, h. In this example of my invention the fallers H each consist of a piece of wire bent into U-shaped form, and having legs If h, the leg h being longer than the leg h. The longer leg, 7L2, of the faller is fitted to move freely vertically in guiding-holes h h while the shorter leg, h is fitted to a guide or guiding-notch, it, formed in the edge of thc' flange h. The faller H can therefore rise and fall freely in its holder or frame, and thelower end of the shorter leg, h is bent inward or as by so doing the shouldered or bent end of said leg is enabled to pass upward over the flange h. The lower edge portion ofthe holder or frame H forms an abutment, h, as will be hereinafter described.

I designates a bar or member, which extends approximately horizontal and parallel with the abutment a, formed by the lower edge portion of the holder H, and the bar I is so mounted or supported that it is capable of a to-aud-fro movement transversely toitslength and across the plane of the abutment. In the present example of my invention the bar I has downwardly-extending arms 2', which are pivoted at z", and upon these pivots the bar or member I rocks to and fro immediately beneath the abutment 71 In the normal operation of the machine, and while the threads 8 are iutact,the threads themselves hold the fallcrs in the elevated position Shown in Fig. 3, and the lowerends of thclegs h are above the abutment h. On the breaking of a thread, however, its faller II will fall until its upper portion strikcs'the rail 71, in which position the leg h will project below the lower edge of the abutment If, as shown by dotted lines in Fig. 3, and directly in the path of the rocking or swinging bar I. The faller will therefore form an obstruction which will arrest the movement of the bar I, and which, through mechanism hereinafter described, will react through the connections which operate the bar to release the driving mechanism and cause it to be thrown off or shifted to stop the reel.

I have here represented the stop-motion shaft as composed of two sections, D D, arranged in line and serving a purpose hereinaftcrdescribed, andthe second section, D, imparts motion to the rocking bar I by mechanism which I will now describe, and which is shown in Figs. 1, 5, and (l. The sections of the shaft D D are mounted in suitable bearings, d, and upon the end of the section D isa carrier, d, here shown as made in the form of a disk, and which carries a crank-arm, d". From the crank-arm d a rod, (1", or other suitable connection,cxtends to the creel, and is jointed to an arm, 2", on the rocking bar I. But very little force is required to rock the bar I in the normal operation of the machine, and the crank-arm d is so connected with its carrier d that when any unusual resistance is opposed to the movement of the bar I, as will be produced by the protruding ofa faller in its way, said crank-arm d will yield relatively to the carrier. I have here shown the crank-arm d" as pivoted at (1 to the carrier plate or disk d and ICO rier d are rotated in the direction indicated by the arrow in Fig. l the arm d will act as a crank to transmit to the rod (1 a reciprocating movement equal in length to double the distancebetwcen the center of the stop-motion shaft and the point of connection of the rod (Z with the crank-arm d During such normal operation the spring (2 will of course be slightly extended, but as the resistance is uniform the cam end at of the crankarm d -will have about the projection from the edge of the disk d, which is shown in Fig. 1.

The clutch-lever E is connected by a horizontal rod, E, with a footlever, E, which is fulcrumed at e to swing in a horizontal plane, and which has connected with it a spring, 0 for moving it in the direction indicated by the arrow in Fig. 6. In this example of my invention the longitudinal rails or stretchers A, forminga part of the framing of the machine, are composed each of two tubes arranged one above. another, and the lever E may be guided at its free end between the two tubes composing one of the stretchers or rails A, as shown in Fig. 1. Incase of any other construction of the framing the said lever should of course have at its free end some other suitable guide or support. I 7

It is obvious thatin the absence of any stop or latch to prevent,the spring 6 will move the lever F. in the direction indicated by the arrow in Fig. 6, and through the rod E and 1e ver E will throw off the clutch which connects the shaft 0 with the driving-pulley O, and therefore stop the reel and the stop-motion shaft D D. To prevent this throwing off of the driving mechanism, I employ a latch or movable stop, and I have here represented such a latch, J, as pivoted at j, and having near its free end a shoulder, j, and in rear of said shoulder an incline, j. It will be understood that when the lever E is moved so that the shoulderj of the latch drops in front ofit,

as shown in the drawings, the driving mechanism will be maintained in operative condition, and that when the latch J is lifted so as to carry its shoulder j clear of the lever E said lever will be at once moved by the spring 6 and will throw off the driving mechanism. The latch J, as here shown, is approximately parallel with the stop-motion shaft D D and projects across and above the circular path described by the cam d of the crank-arm d.

In the normal operation of the machine the cam d has so little projection beyond the edge of the carrier-disk d that it clears the latch J at each revolution; but when the bar I is obstructed by a faller droppingin front of it the undue resistance which is opposed to the movement of the crank-arm at will extend the spring d and the cam 01 will be thrown out and will describe the path indicated by the dotted line 0 in Fig. 1. The cam will then have such projection beyond the edge of the carrier-disk d that when it is brought by the rotation of said disk to th'elatch J it will make contact therewith and lift the latch J, so as to release the lever E The driving mechanism will then be instantly thrown off, so as to stop the reel until the broken thread is joined and the machine again started. Ihave also shown a second lever, E similar to the lever E as connected with the rod E, and by means of this lever E the rod E and lever E with the lever E", may be moved in a reverse direction to that indicated by the arrow on the lever E in Fig. 6, so as to bring the lever E again into position for the latch J to engage withit, and thus start the machine.

The section D of the stop-motion shaft rotates synchronously with the reel, and it is important to have said shaft formed in two sections, as described, and to have the two sections connected by a clutch which provides for lost motion between them, because the reel and first section, D, of the shaft willthen'rotate for a short interval without imparting any motion to the second section, D, of the shaft from which the bar I receives motion. Under such conditions the reel will make a part of a turn before the bar I commences its movement, and by such initial turning of the reel the threads 8 will all be drawn taut and the fallers H will all be lifted out of the reach of the bar I before it commences its operation.

In this example of my invention the clutch consists of a disk, K, which has a grooved periphery engaged by a pin, it, on the lever E and which receives within its bore the end of the shaft-section D. The disk K has a projection, 70, which engages an arm, Z, on-the shaft-section D, and which, when thesections D D are in the relative position in which they are stopped, permits a partial revolution of the section D before any movement is transmitted to the section D.

In this'example of my invention the disk K slides upon the shaftsection D and has projecting from its one side an arm, m, which is engaged by the arm in, secured on the shaftsection D by a set screw. The arms m m serve as a simple means of driving the disk K from the shaft-section D, and still permitting the disk to slide on said shaft-section D. On the shaft-section D is secured an arm, I, and by 4 shipper or lever for rendering the driving mechanism operative or inoperative. J designates the latch or hook by which the lever is held with the clutch in operative position, and c is the spring whereby the clutch is moved into inoperative position when the latch is thrown off.
