WINDING MECHANISM.

Application filed March 15, 1924.

This invention relates to winding mecha nisms and more particularly to improvements in distributing devices therefor.

In certain types of strand working machines, such as those which serve tinsel or other fragile material, it is essential that the tension or stress on the strand material, be ing distributed onto a take-up spool, be kept constant, so that such material may not be distorted or broken.

An object of this invention is to provide a distributor adapted to relieve undue stress or tension imposed upon the material being distributed.

Another object of this invention is to provide a distributor which is actuated independently of an associated winding mechanism, with means to relieve deleterious stresses or strains imposed upon the material being wound.

A further object of this invention is to provide an improved distributing device capable of a simple and inexpensive construc tion.

To these ends a distributor made in accordance with this invention consists of a reciprocating member and an arm suitably secured thereto, the arm comprising guiding means, a support for the guiding means and resilient means normally holding the said guiding means at right angles to the direction of travel of the reciprocating member, the said guiding means being adapted to pivot upon the support to relieve an undue tension or stress, which has been imposed upon the material being distributed. In the under spool type distributor the guiding means may take the form of a linger, whereas in the over spool type distributor the guiding means may take the form of a sheave.

Other objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate two embodiments thereof.

In the drawings:

Figs. 1 and 2 are front and plan views, respectively, of an under spool type distributor arm,

Figs. 3 and 4. are plan and front views, respectively, of an over spool type distributor,

Serial No. 689,442.

Fig. 5 is a diagrammatic view in elevation showing the under spool type distributor applied to a tinsel serving machine, and

Fsg. 6 is a diagrammatic view in elevation showing the over spool type distributor applied to a tinsel serving machine.

Referring now to the drawings in detail, in which like reference numerals designate similar parts throughoutthe several views, the improved under spool type d'stributor (Figs. 1 and 9.) has an arm which comprises essentially a finger ll) secured to a bracket 11, a support 12 to which the bracket ii is pivotally secured by a pin 13, and a tension spring 14: fastened at one end to a threaded stud l5, projecting from the support l). and at the other end to a threaded stud 16 pro 'jectingfroni the bracket 11. The distributor arm is adapted to be mounted on a reciprocating shaft 20, actuated by any suitable means (not shown) and held in place thereon by a set screw 17 which engages a threaded hole 18 in the support 12. It will be noted that the tension of the spring 14: may be varlied by adjusting the threaded studs l5 one 16.

The over spool type distributor (Figs. 3 and l) has a arm which comprises essentially a sheave 30, a member 2-51 on which the sheave is pivotally mounted, a support 3; to which the member 31 is pivotally secured and a tension spring fastened at one end to a stud 3d projecting from the member 31 and at the other end to a stud 35 projecting from the support 32. This arm may also be mounted on the reciprocating shaft 20 and held in place thereon by a set screw 36, which engages a threaded hole 37 in the support 32.

Referring now to Fig. 5, represents generally an under type distributor arm, as shown in Figs. 1 and 2, mounted on the reciprocating

shaft

20, and 53 represents a serving spindle, for serving material to a strand 5a which is wound upon a take-up spool. 55 secured upon a shaft 56 driven by a belt 58 cooperating with a pulley 57 attached to the shaft 56.

In Fig. 6 an over type distributor arm 51 (as shown in Figs. 3 and 4) is substituted for an under type distributor arm 50, the remaining parts being the same as those shown in Fig. 5.

The operation of the distributing device in connection with a strand working machine is as follows:

The strand material 5st (Figs. 5 and G) is drawn from the serving spindle by the take-up spool 55, which is driven by a belt 58, connected to any suitable driving means (not shown), through the pulley 57 associated therewith. The strand material 5% is distributed on to the spool 55 by the distributor arm 50 or 51.

Should the rotation of the serving spindle 53 be for any cause arrested, the distributor arm 50 or 51 would continue to re ciprocate and the take-up spool may continue to rotate inasmuch as both are operated independently of the serving spindle. Upon the spool 55 drawing the strand 54L taut the belt 58 may slip on the pulley 57, the distributor arm, however, would continue to reciprocate.

It is readily apparent that the length of the strand 5% from the spool 55 to the serving spindle 53, when the distributor arm is in the middle of its traverse, is much less than when the arm is at the end or? its traverse. Since the strand 54 is being drawn taut all the time by the spool 55 the reciprocating arm after passing the center of its traverse would be caused to pivot upon its support thereby preventing the strand be- I the support to relieve an undue tension imposed upon the material guided thereby dur ing a predetermined portion of the movement thereof, and means resiliently opposing the pivotal movement of the guiding means.

3. A distributor comprising a movable support, material guiding means mounted thereon, said guiding means pivoting upon the support to relieve an undue tension imposed upon the material guided thereby during a predetermined portion of the movement thereof, means resiliently opposing the pivotal movement of the guiding means, and means for varying the eitectiveness oi the last-mentioned means.

i. A distributor comprising a support, reciprocable in a predetermined path, a material distributing arm pivotally secured to said support, threaded studs carried by the support and arm, and a spring interconnecting the studs and normally holding the arm at right angles to said path, said studs designed to vary the effectiveness of the spring.

5. In a winding machine, a sha it for supporting a spool, means tor rotating the shaft, a support, independently reciprocable along a path parallel to the axis of the shaft, an arm pivotally secured to and carried by the support, resilient means interconnecting the support and the arm for normally holding the arm at right angles to said axis, and means carried by the arm for guiding material to a spool mounted upon the shaft, said resilient means so designed as to permit a change in the angular relation of the arm to the axis of the shaft when the shaft is stopped during a predetermined portion of the reciprocation of the support.

In witness whereof, I hereunto subscribe my name this 23 day of February A. 1).,
