, ning-Jennies and other Textile Machines, of

which the following is a specication.

The object of my invention more especially relates to the laying of yarn upon a bobbin, and facilitating the operation of doing the same, as well as laying a considerably greater quantity of material upon the bobbin, than has hitherto been done; Valso to make the iii'er arms shorter,'so that a flier may be safely run at a higher speed than is usual, inasmuch as the arms connecting the heads being short, the torsional 'strain is to a great extent relieved, and the liability ofthe arms to burst by reason of the centrifugal force generated when in rapid motion, is avoided. Fliers of my newly invented construction may be incorporated in jennies as at present constructed, by simply substituting my Hier-for the usual iier and all its building and traverse mechanism necessary to efficiently' perform the operation of winding the bobbin.V

In the accompanying drawings, Figure 1 represents a side view of my newly-invented hier. Fig. 2 is a front view, partly broken, of one head and sectional on the line .e e', Fig. 1. Fig. 3 is a part longitudinal section. Fig. 4 is a detail view illustrating the operating and reversing mechanism for the traverse-ring. Fig. 5 is a front view of one head, showing gear-operating capstans. Fig. 6 is a perspective view showing adjustment for stop-pins.

A represents a flier of my invention which is mounted in bearings formed in a' jenny frame in the usual manner, and which rotates on the hollow trunnions A', A2, which form part ofthe face plates B, B. The hollow trunnion A receives the hollow spindle G to conduct the yarn S, andthe hollow trunnion A2 receives the hollow tube K through which the spindle R2 is passed.

The plates B, B', are connected together by the arms E, E', which are secured by nuts at their outer ends, the arms having suitable collars, formed on their ends, to allow of rigid and accurate adjustment.

Secured to the plate B by the studs F, and

plate F,are the tension capstans F5, provided with the necessary driving gears F2, F4, and pinion F6, which forms part of the hollow tube G. On one end of the arm E, a guide F2, is

\ secured on a suitable stud, and on the other end of the same arm is secured a similar guide'FSl. A ring H travels loosely on the arm E, and to it a clip H is attached for securing thereto the chain or cord H2. The plate B has formed in its front face a recess ct-a portion of which is extended outwardly, to receive and contain the reversing lever a', and operating lever d2 with its spring al".

Within the hollowtrunnion A2 is a hollow tube K which is provided at its outer extremity with asmall faced driving plate K', having a projecting button head pin K21 secured to its front face, and intended to engage a suitably formed slotted hole inthe head of a winding bobbin R. A spindle R2 passes through the tube K, and bobbin R, and rests at its outer en'd in a hole centrally formed in the plate F.

The tube K at the back of the plate K has an eccentric, or cam K2, formed on its outer surface the diameter'of which corresponds with the hole in the hub L of the inside and outside geared ringf, ofthe plate h. The outer end of the tube K is provided with an adj ustable locking collar K3. On the hollow trunnion A2, a driving pulley is secured by a key, or set screw, and a driving p ulley R is similarly secured to the tube K, at its outer end. In the recess a. of the plate B are located the external toothed ring d which hasV fifty nine teeth on its outer face, and the internal toothed ring d which has sixty one teeth formed on its inner face, of about the same pitch. Located in'the same recess a is a vibrating pawl, or tappet a', which has a double knife edge projection d5, so formed as to lock the teeth of the ringd, when in one position,vand the teeth of the ring d,when in another position to the plate B. The reversing tappet o. has a flat upper edge a4, to engage a curved face a6 formed on the rocking, or operating lever d2, both tappet and lever being located upon -suitable pivotal screws a7, 0,2, Fig. et. A ring f which forms a part of the plate h is also` partly inserted in the recess d, of the plate B', and is provided with sixty external, and sixty internal teeth, f', f2, of the same pitch as the teeth of the rings cl, d', with which IOO they may engage. The hub L of the face plate h is bored to suit the cam, or eccentric K2, which rotates therein freely.

The periphery of the plate h, has an annular groove h2 formed therein, within which a coil tension spring P, is partly inclosed, one end of which is secured to the bottom of the groove h2 by a rivet, and the other end by a suitable eye, is secured to the free end of the chain, or cord H2. On one end of the edges of the plate h, nearest the plate B stop pins k k may be adjustably located (as in Fig. 6), and which extend 'outwardly a sufficient distance to enable either one to strike the pin a2, on the reversing lever a3, as the plate 77, revolves to the right, or left. A spiral cornpression spring al@ gives a pressure to the lever arm a2, when thrown to either side of the center by the pins 7c 7a.

I will now further explain the operation of my newly invented devices.

The bobbin R when empty being placed within the ier, the spindle R2 is passed through the tube K, and hole in the bobbin R, resting in the cavity in the plate F. The end of the yarn S is drawn through the tube G, and wound around the tension capstans F5, and thence partly around the guide F2, and along the flier arm E, to, and through the ring Il, and then passed two or three times round the bobbin R, which is then locked to the pin K21. Motion by belt is then given to the hier pulley B2 which revolves the flier at any desired speed. Motion is also given by a suitable belt to the capstans F5 through the gear F2, F4, F, in the same manner as i'n general use. Motion is also imparted to the bobbin R, by the stud pin K21, face plate K,tube K, and pulley R', which is driven in the usual manner by a suitable belt. The speed of the flier A is so arranged, that it shall exceed the speed of the bobbin R, so that tension may be given, sufficient to lay the yarn S upon the surface of the bobbin R. The faster motion by the iiierA in covering the bobbin R, causes the bcltto slip on the pulley R and imparts the necessary amount of friction to hold the yarn S in tension, in the same manner as in jennies in present use. The difference of revolution between the flier and bobbin, or that used `for covering the bobbin R with one turn of yarn, I utilize `by my device to regulate the traverse, or laying mo,- tion in the following manner: The pins 7c, 7c secured in the holes 7022 on the plate h, are located a suitable distance apart so as to strike the pin a9 of the reversing tappet a2, according to the length of the bobbin to be covered. The `plate B being locked to the ring d by the double pawl A5 pivotally `secured to the plate B engaging in one of its teeth,the ri'ng d is caused to revolve with it, the external toothed `ring d being disengaged and running idle. The plate h by its hub L with 'its Linternal and external teeth f,f2 is lifted by the cam K2 of the tube K4, which by its plate l K and pin K21 is locked to the bobbin to `be covered, into alternate engagement with the rings d, d; the teeth f with teeth on the ring d and the teeth f2 with teeth ou the ring d. In thus engaging and disengaging during a revolution of the tube K the ring 7L is moved around the cam a distance equal to one tooth by reason of the difference in number of teeth in the rings d, d', those on the plate h being equal. The advance of the plate one tooth win ds the chain or cord H2 located in groove h2 and secured by spring P in the same upon the plate 7L and by the guide F2, clip Il', and ring H, draws the yarn S along the arm E of the iier A the distance equal to one tooth or the diameter of the yarn to be laid. The tension on the spring P, and chain or cord H2, is given by the'strain on the yarn S through its delivery from the capstans, the same being regulated in the usual manner. This laying or building rnovement continues regularly until the Whole length of the bobbin is covered and the pin 7o has approached and touched the pin a2, on the reversing lever a3, Which is thrown slightly out of the center line. The spring d10 then `exerts a force and completes the travel of the lever a2 with a snap. The lower face a6 of the lever a3 then coming in contact with a `corresponding upper edge CL4 of the rocking lever a', the knife edged pawl a5 is withdrawn from engagement With the teeth of the ring d', and inserted into and locks the teeth of the ring d. The plate h with its ring f and hub L rotating on the cam or eccentric K2 formed o'n the tube K, then begins to move in the opposite direction letting out tooth by tooth, or lay by lay, the chain or cord H2 which has been wound on the groove h2 of the plate h, by the previous movement, and permits the ring I-I to be drawnalong the arm E by the tension of the yarn S, until the bobbin R is again covered with another layer `of yarn, and the pin k again strikes the reversing pin a2, and so on alternately until the bobbin is com pletely filled, when it is removed and replaced by another bobbin. It may be seen that the motion forward is ygained by the difference in n'umber in the teeth of the vring d and those on the plate 71 and the return movement by those on the ring `d and those of the plate h. I may mention asa'n illustration to more fully describe this motion, that three annular rings `of different diameters one of which located within the space formed by the outer diame- 'ter of the smaller, and the inner diameter of the larger, when placed in a vertical position, fand rolled along a fiat plane the inner and outercircumferences of the rings at the termination of 1one revolution will have traveled a varying'distance, although each ring will have made a complete revolution. Should the point of contact be With the middle ring and Athe smallest ring the motion will be in one direction, and if with the middle ring and the largest, the motion will `be in another direcf tion the surfaces gained or lost in the operation representing the teeth I gainor lose and IOC IIO

use to'operate the traverse ringH of my newly invented iier.
