SPINNING SPINDLE.

Application filed June 2, 1925. Serial No. 34,305.

This invention relates to spinning spindles such as are generally used in silk and cotton mills, and, broadly considered, has for 1ts principal object and purpose to provide sunple and easily operated means for throwing the spindle out of engagement with the driv ing wheel and quicklybringing the spindle to a complete stop so that the operator may have the free use of both hands in connecting up the end of the thread.

It is another and more particular ob ect of our invention to provide a pivotallymounted lever having means to coact with the pivoted spindle carrying arm whereby when the lever is moved in one direction the spindle is thrown out of engagement with the face of the driving wheel, and an adjustable brake means carried by said lever and adapted to automatically engage the rotating spindle as the latter is moved away from the driving wheel whereby said spindle is quickly brought to a complete stop'.

It is also a further object of our present improvements to provide a novel mounting of the spindle releasing lever and a simple and effective latch means therefor to retain said lever in its release position.

\Vith the above and other objects in view, the invention consists in the improved releasing device for spinning spindles, and in the form, proportion, and'relative arrangement of the several parts thereof as will be hereinafter more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims.

In the drawings, wherein we. have shown one simple and satisfactoryembodiment of the invention, and in which similar reference characters designate corresponding parts throughout the several views,-- Figure 1 is a side elevation illustrating one embodiment of our present improvements;

Fig 2 is a front view thereof;

Fig. 3 is a plan view, the spindle being shown in section and in engagement with the driving wheel, and

Fig. f is a similar view but showing the relative position of the parts after the spindle has been disengaged from the driving wheel. I

For the purpose of illustrating one application ofour inventiomin the accompanying drawings we have shown a pair of vertically spaced, horizontally positioned rails 5 which extend along the front of the machine and upon which the spaced spindle supports are mounted. stance, we have shown these rails as of cylindrical form and each of the spindle supports includes a pair of plates 6 and 7,

In the present in respectively, which are provided in their 7 opposed faces with concave seats to receive the rails 5. Between said rails these plates are connected with each other by means of the bolt 8 whereby they are rigidly clamped upon the rails.

The plate 6 at is upper end is formed with a laterally projecting arm 9 upon which the angular spindle carrying bracket 10 is pivotally mounted at one of its ends, as at 11. The spindle 12, which is rotatably supported in the other end of this bracket may be of any conventional type and is provided with a cylindrically enlarged section 13 for contact with the facing 15 on the driving wheel 14, said facing preferably consisting of leather or other suitable material of light frictional character. 7

The plate 7 is provided at its upper end with a horizontally projecting lug 16 upon which the lever 17 is supported intermediate of its ends for free pivotal movement about a bolt 18 threaded or otherwise fixed in said lug. Between the head of said bolt and the lever 17 a coil springlt) is interposed. One end of the lever .17 is provided with a downwardly projecting finger 20 positioned against one side of the spindle carrying arm 10 at the upper end thereof and adjacent to its pivot 11. I j

At the opposite side of the pivot bolt 18 with respect to the finger 20, the lever 17 has a tooth 21 formed on the under side thereof adapted for movement over a series of rack teeth 23 formed upon the end of a lateral extension 22 on the upper end of the plate 7. By this means the lever 17 is held againsta casual pivotal movement on the bolt 18, the spring 19 acting upon said lever to maintain its tooth 21 in engagement with the teeth of the rack 23 but readily yielding so that said tooth 21 may move over the rack upon the application of lateral pressure against the end of the lever.

The end of the lever 17 which is provided with the finger 20 also has a'pin or stud- 2i projecting upwardly therefrom. This pin is loosely eng gaged in an opening formed in an arm engaged upon the upper side of the le er 17. This arm at one end is formed with an obliquely inclined curved section 26 extending over the driving wheel l t and located at one side of the spindle 12. The end of this curved section 26 of the arm provided with a suitably formed holder for a brake shoe 2? of a suitable frictional material.

The inner end of the arm 25 is provided with a slot 28 extending at right angles to the axis of said arm, said slot receiving a screw 20 which threaded in the lever 17. By means of this screw 29, the arm 25 may be securely clamped in an adjusted position upon the end of the lever whereby the brake shoe 2? may be caused to properly bear upon the spindle with the described frictional pressure.

Having above described the several mechanical features of the device, its operation will be understood as follows. Assuming that the spindle is being driven by frictional contact of the facing leather 15 on the driv ing wheel 14 with the part 13 of said spindle, and that it is desired to release the spindle from such driving engagement with the wheel, this may be easily done by simply moving the outer end of the lever 17 to the left from the position shown in Fig. 3 of the drawings. The finger 20 on said lever is thus caused to bear against the pivoted arm 10 and swin said arm to the right, thereby carrying the part 13 of the spindle away from the driving face of the wheel 14. In this movement of the lever 17 the brake shoe 27 is automatically brought into frictional bearing engagement against the part 13 of the spindle in the manner illustrated in Fig. 4 of the drawings, as it will be observed that the arc of movement of the spindle is much shorter than that of the brake shoe. Thus when the spindle reaches its disengaged position, it is simultaneously engaged by the brake shoe 27 so that the frictional resistance oll'ered by said shoe quickly brings the rotating spindle to a complete stop. Thus, the operator may employ both of his hands in connecting up the loose end of the thread and it is not necessary for him to first stop the rotation of the spindle. After the connection has been made, the lever is again moved to its former position as shown in Fig. 3 and the spindle returned to its opcrative position in engagement with the driving face of the wheel 14. If desired, it will be understood that a suitable spring may be provided acting upon the arm 10 to normally hold the spindle in the latter position. However, in the present instance, the operator after connecting the thread, moves the spindle a m 10 by hand, and said arm being against the finger 20 on the lever shifts the lever over the raoh 28 against the action of the spring 19.

From the foregoing description considered in connection with the accompanying drawing, the several features of our pres nt improven'ients and the advantages thereof in practical use will be readily understood. Thus, we have found that by means of such a device, a gain of approximately in the speed. with which such spinn' machines may be operated can be attained. By means of our improvements, a single spindle, or as many spindles as desired can be quickly thrown out of operation at any time, thereby reducing wear upon the} leather friction surface of the drive wheel or wheels and correspondingly reducing the expense incident to the replacement of such friction surfaces and prolonging the life thereof. I

l ve have herein disclosed what we regard as a practical and satisfactory embodiment of our present in'iprovemcnts. Nevertheless, it will be apparent to those familiar with this that the d vice mi h also be incorporated in various other al native constructions, and we therefore, rcserve the privilege of adopting all s legitimate changes in the form, proportion and relative arrangement of it several par; as may be fairly embodied within the spirit and scope of the invention claimed.
