THREAD-BREAKING DEVICE FOR- SPINNING MACHINES.

Application filed January 23, 1925.

To all whom it may concern:

Be it known that we, FERDINAND Q. HART- MAN and EUGENE A'rwoon HARTMAN, citizens of the United States, and residents of Danville, in the county of Montour and State of Pennsylvania, have invented a new and useful Improvement in Thread-Breaking Devices for Spinning Machines, of which the following is a specification.

Our invention relates to a thread breaking device for spinning machines and more particularly to a thread breaking device which may be applied to spinners for independently spinning a plurality of threads and winding the threads so spun on a single spool, from which spool the threads are sub sequently to be twisted into one strand on a twisting machine. spinning a plurality of threads at the same time and winding them together on a spool or bobbin, that a single thread or aless number than the whole number of threads being spun, be not allowed to run onto the spool as this would produce a serious defect when the threads sospun are finally twisted into a. strand. v

Our present invention is directed to a thread breaking device which may be interposed between the spindles and the take up spool upon which the spun threads are wound, and which shall be under the control of thread supporting devices carried by the breaker, to perform the function of breaking a companion thread when another thread is unintentionally parted, so that the several threads may be united before any one or more of the threads has or have been allowed to be wound upon the take up spool without its or their companion thread or threads.

The object of our invention is to provide a device of this character whichis efficient, positive in operation, simple in construction, and inexpensive to manufacture.

Another object consists in providing a device which has a thread guiding bar mounted to oscillate on the thread breaker, which is located in position to be thrown off center by the rocking movement of the bar, which movement is actuated by the breaking of a thread.

Another object is to provide a device having a horizontally disposed bar rotatably mounted in the device for supporting the It is very essential in.

threads and relieving the bar of certain frictional contact as the thread passes thereover. Another object is to provide a structure having guide arms vertically disposed to spread or separate the threads laterally on the supporting bar of the thread breaker.

Another object is to provide novel means of mounting the device on the thread breaker so that the device may be limited in its oscillatory movement thereon.

Another object consists in providing certain improvements in the form, construction and arrangement of the several parts whereby the above named and other objects may be effectively attained.-

A- practical embodiment of our invention is represented in the accompanying drawings, in which i Fig. 1 represents a front elevation of the device in operative position so much of. a spinning machine being shown as will suflice to disclose apractical application of'our invention. t

Fig. 8 represents a vertical section taken in the plane of the line VHF-VIII of Fig. 6. looking in the direction of the arrows.

In the form shown in Figs. 1 to 3 inclusive. the main frame of the machine at one. end is denoted by 1. the take up spool by 2, the traverse guide for assembling the threads and laying them on the take up spool. by 3, the wheel for driving the take u up spool by 4, and a pair of spindles for spinning two independent threads by 5, 6.

The bobbins which carry the threads are mounted on the spindles 5 and 6 in the usual machine.

manner and are indicated by 7 and 8. The a threads which lead from the respective bobbins 7, 8 are denoted by 9 and 10. For the purpose of supporting the thread breaker mechanism in proper position on the spinning machine so that there shall be one for each group of threads to be combined on a single take up spool, we secure a horizontal rail 11 to the end frame of the spinning This rail may be composed oi" wood so'as to receive screws 12 for attaching the brackets 13 of the thread breaking mechanism in position. Each bracket 13 1s provided with a frame 1 1- having depending lugs 15, 16 arranged to receive a pintle 17 upon which is mounted a thread breaker 18. The thread breaker 18 comprises a downwardly extending arm 19 having a cross :head 20 which terminatesin hook eyes 21, 22, and an upwardly extending arm 23 which is so weighted as to overbalance the downwardly extending arm 19. Upon the upper'end of the arm 23 there is mounted a thread guiding device, which comprises, in the present instance, a rectangular block 24 having a horizontally disposed bar 25 mounted to rotate therein- This bar 25 e2:-

tends in opposite directions from the block 24 and is maintained in this position by means of wire collars 26, 27 secured thereto. The block-is secured in position to oscillate on the ar1n23 by means of a U-shaped element 28 having a member 29 arranged to pass'through anop'ening 30 in the block 24 and to be seated in a recess 31 in the arm 23. The other member 32 of the element 28 extends downwardly and is provided with a. laterally turned end 33 which enters a hole in the arm 23. The members 29 and 32 of the element 28 are arranged to yield so that the end 33 will be normally heldin the hole 34.

A pair of guide arms 35, 36 are disposed in the frame 141 andextencl upwardly and outwardly in front of the rotatable bar 25 so as to hold the threads in position upon opposite sides of the block 2 1 as they pass over and from the bar 25.

A guide eye 37 is secured to a support 38 fixed to the frame 14, by means of a screw 39, which guide eye 37 tends to assemble the threads in their passage upwardly and over the traverse bar 3 to the take up spool 2.

In the modified form shown in Figs. 42 and 5, the guide arms 10 and 41 are disposed in a frame 42 and extend upwardly and outwardly therefrom. Each of the guide arms 40, 4:1 is provided with a guide eye-or pigtail 13 arranged in opposite relation and serves-to holdits thread in position'on a rotatable guide bar 44 carried by a rectangular block 45, which is mounted to oscillate on aU-shaped element 46 secured to the upwardly extending arm 47 or" the thread breaker 48.

lVhile we have specifically described the block and its adjacent parts as shown in Figs. 1, 2, 3, 6, 7 and 8, we wish to particularly point out the fact that the breaker 18 with its rectangular block 45 and its adjacent parts as shown in the modified form in Figs. 4 and 5 and operation.

In operation of the structure shown in Figs. 1 to 3 inclusive, the threads which lead from the bobbins 7, 8 are directed upwardly upon opposite sides of the breaker 18', over the rotatable bar 25, thence outwardly and substantially at right angles thereto, thence partially around the guide arms 35, 36 in wardly to the guide eye 37, where they are associated and travel upwardly over the traverse bar 3 onto the take up spool 2. 11 during the operation of the machine, one of the threads 9, 10 accidentally breaks, the tension on one end of the rotatable bar 25 will be relieved and the drag of the unbroken thread on the opposite end of the bar 25 will cause the block 24; to rock or swing arcuately on the member 29 of the element overbalance the breaker 18 and cause the upwardly extending arm 23 to move rearare identical in structure wardly by grai'ity and the downwardly eX- tending arm 19 to swing forwardly'to the position shown in dotted outline in Fig. 2. in this position the crosshead 20- with its book eyes 21, 22, will be brought into the path of the whirl of the unbroken thread, which will be caught by one of the hook eyes 21, 22, form a loop therein, which will promptly break the unbroken thread. Thus the operator will be enabled to join the broken ends of each of the group of threads being wound upon the take up spool 2, so that there may be, at no time, any distance of single thread wound on the take: up spool and the defect which would otherwise take place in the finally twistedstrand is thereby avoided.

In operation of the form shown in Figs. 4 and 5, each of the threads after passing from the rotatable 13211344: on opposite sides of the blocker), is directed through the guide eye or pigtail 4 3, thence upwardly to be as,- sen'ibled at the traverse bar and spool (not shown). i
