HERBERT W. OWEN, OF DOVER, NEW HAMPSHIRE, ASSIGNOB TO DRAPER COMPANY, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.

SPINNING-FRAME.

Specification of Letters Patent.

Application filed November 22, 1911.

To all 'whom it may concam.'

Be it known that I, HERBERT W. OWEN, a citizen of the United States, and a resident of Dover, in the county of Straiford and State of New Hampshire, have invented certain new and useful Improvements in Spinning-Frames, of which the following is a specification.

This invention relates to spinning ma chines, and has particular reference to mechanism connected with the ring rail to effect the changes in its vertical position.

When dofting, the ring rail is usually moved to a position below its lowest eXtreme when traversing, to facilitate access to the bobbin. Then the machine is run slowly, as by working the shipper lever back and forth, so as to give slack yarn to enable the' full bobbins to be removed, and to furnish the slack yarn to be fastened ready for the operation on the new bobbins. Then when the g new bobbins are all in place and the machine any stoppage, it is customary to go through the same operation which is aptly called jiggling. Without considerable practice, this jiggling is liable to be excessive, and furthermore it requires considerable physical edort.

The object of my present invention is to provide means whereby this jigglin'g, or series of short traverses, may be imparted to the ring rail whenever desired, by power, thus avoiding the expenditure of physical effort by the dolfer, and causing such short traverses to be uniform and with a predetermined degree or amountnof motion.

To these ends, the invention consists in the construction and combination of parts, substantially as hereinafter. described and claimed.

Of the accompanying drawings,-Figure 1 is a front elevation of so much of a spinning machine as is necessary to illustrate my invention in one of its embodiments. Fig. 2 is a detail end view, looking from the left of Fig. 1.

"the usual gear of the machine.

Similar referenceI characters indicate the same or similar parts in both the views.

The spindle rail 15 supports the spindles in the usualmanner, and the ring rail 17 carries rings for travelers, said ring rail being supported upon lifter rods. To avoid unnecessary drawings, only one spindle is shown, as at 16, one ring 18, one traveler 19, and one lifter rod 20. The complete machine has a plurality of lifter rods each actuated in an upward direction by a rocker 21 under the influence of weight 22. The' rocker 21 has an arm 23 from which a link 24 extends to another rocker arm for another lifter rod. The rocker arm is provided with the usual segment 25. This segment 25, in a well known type of spinning frame, is connected by a chain with the builder motion. In the present drawings, such builder motion and the chain therefrom to the rocker arm are omitted to avoid confusion. As shown in the accompanying drawings, however, there is a chain 26 connected at one end to the segment 25 from which it passes under' a sheave 27 carried by a bracket 28 thatis supported by the end frame of the machine. From said sheave 27 the chain passes upwardly and over a sheave 29 carried by one end of a lever 30 which is pivoted at 31 on a pin or stud shaft projecting from the frame of the machine, the other end of said lever 30 carrying a roll 32. From the sheave 29 the chain 26 passes downwardly and is secured to a rotary stud 33 as by being passed through a transverse aperture in said stud and the end of the chain having a cotter ring 3&1(` The stud .33 is rotatively mounted in the end frame of the machine and has a hand wheel 35 in a position readily accessible to the doffer. In Figf2 the front roll shaft 36 is illustrated as constructed Vand in the usual position therefor, saidA shaft having a gear 37 that is driven by Connected to rotate with said shaft as by being secured to the spokes of the wheel 37 is a cam 38. This cam is illustrated as circular in form but eccentric-to the axis of the shaft 36 with which it rotates.

It is to be understood of course that the shaft 36, and of course the cam 38 also will be constantly rotating at a uniform speed whenever the machine is spinning. The lever 30 is held normally in substantially the ed' at one end to said lever 30 and at the other end to a suitable stationary point. This, or any mechanical equivalent therefor is for the purpose of normally keeping the roll 32 suiliciently spaced from the cam 3S to prevent the lever 30 from being actuated by said cam. Vhenever the dotfer or other operator desires that the ring rail shall be jiggled or have imparted thereto -a series of short traverses, he simply rotates the hand wheel 35 in the direction of the arrow in Fig. 2 so as to wind up the chain upon the rotary stud 83 until by doing so the resulting pull upon the chain will cause the roll 32 to bear against the cam 38. The hand wheel is simply held with suiiicient firmness so that the oscillations of the lever 80 under the influence of the rotating cam will not unwind the chain from t-he rotary stud, but will cause the sheave 29 to exert a pull in the bight or loop of chain passing over it, such pull being then transmitted to the portion of the chain which passes around the .sheave 27 to the rocker arm 23. Owing to the sheave 29 being in a bight of the chain, the amount of motion imparted to the rocker arm will be double the amount of motion that is imparted to the sheave 27 by the cam 38 acting upon the roll 32 at the other end of the lever 30, consequently the amount of eccentricity of the cam 38 need be but very slight.

As long as the hand wheel 35 is held in the manner described, the ring rail will have imparted thereto a series of short traverses, with the same results that have heretofore been'obtained by the doifer pressing his foot upon the foot piece 40 carried by the rocker 21. This foot piece 40 is shown in Fig. 1 of the drawings for the purposes of illustration in connection with the above description, but it will be understood of course, that with my improvement, such foot piece 40 will not be necessary for use to impart the Y short traverses. However, it is desirable to lever 30 constitutes a movable member which is-normally separated from said cam or actuator but is adapted to be manually shifted to position where its roll 32 willengage said cam or actuator so as to result in motion being transmitted through the chain to the ring rail.

I claim:-

l. A spinning machine having means for mechanically traversing the ring rail, said means including a power-operated actuator,`

a movable member normally separated from said actuator and adapted to -be manually shifted to position to be operated vby said actuator, and connections between said movable member and the ring rail to transmit motion to the latter, said actuator and connections being structurally independent of the. builder motion of the machine.

2. A spinning machine having a cam, a lever normally out of position to be operated by the cam, manually operable means for shifting' the lever to position to be actuated by the cam, and connections between the lever and ring rail for causing the latter to be traversed by said lever. i

3. A spinning machine having a cam, a lever having a roll at one end adapted to contact with said cam, a sheave at the other end of the lever, a chain passing over said sheave and connected at one end to the rocker arm of the ring rail lifter mechanism, and means for taking up the other end of said chain. A

In testimony whereof I have atliXed my signature, in presence of two witnesses.
