WTLLIAM ALBERT LUSH, SCRANTON, PENNSYLVANIA.-

FALLER ATTACHMENT FOR SPINNER-FRAMES.

To all whom/ it may concern I Be itknown that I, WIL IAM A. LUSH, a citizen ofthe United States, and a resident of Scranton, in the county ofLackawanna and State of Pennsylvania, have invented a new and Improved Faller Attachment for Spinner-Frames, of which the following is a full, clear, and exact description. This invention relates to attachments used in silk throwing plants or spinner frames, and has for an object the provision of an improved attachment for a faller device where by the thread may be doubled and spun in one operation on the same machine.

Anotherobject in viewis to provide an improved arrangement of faller device for breaking the remaining threads when one thread accidentally becomes broken.

In carrying out the objectsof the inven.- tion the construction is a simple effective arrangement whereby when one thread is accidentally broken in a given set the remaining threads will be automatically broken.

. This is very necessary as it is very essential in spinning a plurality of threads at the same time that all of the threads be supplied so as to be twisted into a single strand. After the threads have been properly doubled on the take-up bobbin said bobbin is removed and placed in a twisting machine where the double threads are twisted, said device, however, not forming any feature of the present invention but is mentioned to illustrate the advantage of the doubling of the threads properly. The present construction is directed to a device for breaking companion threads when one thread is unintentionally broken so that the several threads may be united before any one or more of the threads has been allowed to be wound on the take-up bobbin without the companion threads.

In the accompanying drawings :Figure -1 is a transverse section through part of av spinning frame showing a faller attachment embodying the invention; Fig. 2 is a front view of the structure shown in Fig. 1; Fig. 3 is a rear view of the structure shown in Fig. 1; Fig. 4 is a fragmentary sectional View through Fig. 1 approximately on line 4-4.

Referring to the accompanying drawings by numerals, 1 indicates the usual wood rail of a spinning frame and 2 the usual transverse bar, which bar is provided with a guide 3 for guiding the threads to the take- Specification of Letters Patent.

up bobbin 4, which bobbin is associated with of falls 9and 10. These falls may be constructed of any suitable material andsubstant ally in any suitable manner, the construction shown being a pair of wires supporting theeyes 11 and 12 at one end while the opposite end is wound around a shaft 13. The ends of wires 9 and 10 after being wound around the shaft 13 are formed into arms 14 and 15 which overlap knock-ofl rods 16 and 17, as shown more particularly in Fig. 2. A winding 15 is arranged between wires 9 and 10 merely for the purpose of spacing these wires.

It will be observed that the rods 16 and 17 are made from a single piece of material but are looped around the rod 13. A connecting bar 14 connects the loops while the free ends of the single piece of material form the. rods 16 and 17 which extend downwardly so as to be in the path of travel of the threads 18 and 19 when moved to the dotted line position shown in Fig. 1. As these two rods are connected together the breaking of either of the threads 18 or 19 will cause one of the fall wires 9 or 10 to move over to the dotted position shown in Fig. 1, whereupon the rods will be moved to the dotted position shown in said figure and thereby break the unbroken thread or threads, as the case may be, there being only two threads shown in the drawing but it will be evident that any desired number could be used and doubled on the same takeup bobbin. As shown more particularly in Fig. 2, the threads 18 and 19 after leaving the spools 20 and 21 pass through the spiral tension wires 22 and 23 and from thence through the eyes 11 and 12 to guide 3 so as to be wound together on the take-up bobbin 4. The transverse bar 2 on whichguide 3 is mounted moves back and forth in a well known manner for properly laying the threads on bobbin 4.

' As shown more particularly in Fig. 1, a

. wire 24 is provided for limiting the forward Fig. 1, whereupon the unbroken thread will be broken, thus preventing the winding of a less nmber of threads on the take-up bobbin than the full capacity of the device.

By using this taller device or attachment a thread can be taken from each of the spools 20 and 21 and run separately through the spiral tension wires 22 and 23 and the two eyes 11 and 12 in the top of the fallers 9 and 10 to a single take-up bobbin 4, thus doubling the single thread from the two lower bobbins on to the single take-up bobbin, each single thread being spun after it leaves the lower bobbin, thus doubling and spinning in one operation on the same machine. The spinning part of the operation is produced by the independent rotation of the spools 20 and 21 whereby the threads are spun as they move from the spools to the take-up bobbin.

lVhat I claim is 1. In a device of the character described, the combination with spools and a bobbin upon which the threads are wound, of a support intermediate of the spools and bobbin, fallers pivoted to the front'of the support and having eyes for the passage of the threads,-'each faller being formed of a piece of wire provided with a plurality of coils through which the pivot loosely passes and with arms integral with the coils and standing approximately at right angles to the fallers, said arms terminating in laterally extending portions, and knock-off rods pivoted to the rear of the support and formed of a single piece of material provided with eyes through which the pivot loosely passes, said rods being adapted to be engaged by the laterally extending portions of the said arms to operate them when the fallers are lowered.

2. In a device of the character described, the combination with spools and a bobbin upon which the threads are wound, of pivoted fallers, each formed of a piece of wire provided with a plurality of coils terminating in rearwardly extending arms standing approximately at right angles to the fallers and having at their ends laterally extending portions, the fallers being provided with a guide eye and the coils receiving the pivot thereof, and knock-off rods pivoted in rear of the fallers and in the same horizontal plane therewith, said rods being adapted to be engaged by the laterally extending portions of the said arms to operate them.

In testimony whereof I have signed my name to this specification.

WILLIAM ALBERT LUSH.
