WHIEL FOR SPINNING-FRAMES.

Specification of Letters Patent.

Application filed March 25, 1910. Serial No. 551,435.

To all whom it may concern:

Be it known that I, "WILLIAM ST. PETER, a citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented a new and useful Improvement in Vhirls for Spinning-Frames, of which the following is a specification.

My invention relates to all spinningframes, whether of the cap, ring, twister or other types, wherein the whirl is of that type which is provided with a tube-spindle inas distinguish ed from that type wherein there is no tubespindle, as shown in the patent to Ashworth, Feb. 14, 1905, Serial Number 7 82,535, in Class 1lS-Spinning, spindles and appurtenances; and wherein the whirl is provided with a lug or lugs, usually two, integral parts of the whirl at its base, whereon the bobbin sets in actual spinning operation, the bobbin being provided with corresponding slots to fit over the lugs when the bobbin is seated. These lugs, usually directly opposing each other, and in alinement with the spindle of the whirl, are intended to prevent rotary movement of the bobbin upon the whirl in the spinning operation, but in actual practice they frequently fail to effect this purpose on account of the jumping of the bobbin upon the whirl. This jumping of the bobbin, not only causes loose and imperfect winding and consequent frequent breaking of the yarn or thread, but very materially shortens the life of the bobbin, and also results in great inconvenience, loss of time, waste of yarn or thread, and often, imperfections in weaving.

My invention is intended to overcome these difliculties in connection with the operation of the type of whirl above referred to, which has a tube-spindle, and which is now used in the mills of New England at least, to the exclusion of all other types of whirls for both cotton and worsted spinning by providing comparatively inexpensive, and at the same time thoroughly efficient means to hold the bobbin in its normal position upon the whirl, during the spinning process,consisting preferably of two straight, flat pieces of spring steel, of approximately one-half the length of the spindle of the whirl, of proper width and thickness,which, with one end of each securely fastened to the spindle, and in alinement therewith, with their free ends terminating substantially at the base of the spindle of the whirl, act as friction springs to hold the bobbin in normal position while in operation, the centrifugal force exerted by the high rate of revolution of the whirl, causing the springs by direct pressure upon the inner wall of the bobbin to securely hold the bobbin against both the rotary and jumping movements referred to.

The type of whirl without an integral tube-spindle has, I am creditably informed, been tried and discarded as useless, for three very important and conclusive reasons: 1st, because of the oscillation and insecurity of the mandrel and the bobbin upon the whirl,

except when the machinery runs at its normal high speed, insuring full engagement of the openings in the arms of the mandrel with the pins projecting-from the inner wall of the whirl. 2nd, because the centrifugal force, relied upon to secure the mandrel upon the whirl base, forces the lubricating oil upward on the spindle, and outward between the arms of the mandrel and thenceupon the bobbin and yarn, causing more waste than under the old method. 3rd, because of the frequent clogging of the man drel by the flying waste, which at the usual high speed of the machinery, is thrown off by the rapidly revolving whirl.

The nature of my invention is further hereinafter described and is illustrated in the accompanying drawing in which similar letters of reference indicate corresponding parts.

Figure 1 is a view in elevation of a whirl such as is used in worsted spinning, without the lugs now in use, and with my invention applied thereto, the springs in the position inactive while the whirl is at rest. Fig. 2 is a sectional view of the whirl in the same position as in Fig. 1, with a bobbin seated in outline upon the whirl, and the spring actively pressing against the bobbin wall by the action of centrifugal force. Figs. 3 and 4c are longitudinal views of the spring showing the comparative thickness and width of the steel pieces adapted to the Whirl used in worsted spinning.

a is a whirl such as is now in use in worsted spinning, of actual size, except that the spindle thereof is somewhat shortened for the purpose of this drawing, 6 is the base of whirl upon which the bobbin is seated in operation, 0 is my invention, showing at d the comparative point of attachment to whirl. spindle, and at 6 its termination in the recess of base of whirl, and f is a bobbin outlined in its position upon the whirl.

As more clearly shown in Figs. 3 and 4t it will be seen that the spring 0 is formed of a comparatively thin sheet material having perfectly straight dimensions. This spring is secured to the whirl spindle at I and is adapted to lie parallel with and flat against the spindle, except when under the action of centrifugal force it is caused to buckle or otherwise move from its normal perpendicular position.

While I have chosen to illustrate my invention in connection with a worsted whirl having an integral tube-spindle it will, of course, be understood that the spring is applicable to any similar whirl now in use for spinning woolen, cotton, worsted or other yarn or thread, the springs proving efficient for warp, filling and all fine work as well as for twisting and coarse work.

My spring may be employed eiiiciently upon the old whirl, without the expense of the removal of the two lugs, by placing a "asher on spindle resting upon the lugs, upon which to seat the bobbin.

IVith the use of whirls provided with my springs, I have found it practicable to employ the bobbins which have been thrown aside as useless, on account of the breaking away of their entire bases to the full depth of the slots; and it has been proved in actual operation that these old bobbins, with the perfect winding of the yarn secured by the use of my device, are equally eflicient in the subsequent weaving operation.

In actual operation upon a spinning frame the springs are, by centrifugal force exerted, pushed outwardly against the inner wall of the bobbin. The higher the machinery is speeded, the greater the pressure of the springs.

I am now aware that prior to my invention, frictional means had been devised intended to hold a bobbin upon the whirl during the winding operation, as in Sullivan, May 12, 1903, Serial Number 728,042, and in the case of Ashworth, above referred to, but neither of these devices can be successfully applied to the particular form of whirl now almost universally in use, the Ashworth device being specially limited to whirls without integral tube-spindles. In view of the state of the art as disclosed by these two cases, I do not claim the combination of frictional means in spinning whirls to hold the bobbin thereon in operation broadly; neither do I claim the invention of a new manufacture, but rather the perfection of an old device so as to make it more valuable, in terms as follows.

I claim:

1. A spinning whirl of the type provided with an integral tube, having a straight, fiat, thin, narrow piece of resilient metal attached at one of its ends to said tube, and disposed in alinement therewith, with its free end extended into a shallow depression in the whirl, whereby a bobbin is held in operative position upon the whirl by the pressure of said piece of metal upon the inner wall of the bobbin, exerted wholly by centrifugal force, substantially as described.

2. In combination with a spinning whirl of the type provided with an integral tube, a straight, flat, thin, narrow piece of resilient metal, which, attached at one of its ends to the whirl tube, with its free end extending downwardly in alinement with the tube, into a shallow depression in the whirl, is pressed outwardly wholly by the centrifugal force generated by the revolution of the whirl, and thereby holds a bobbin in operative position upon the whirl, substantially as described.

3. In combination with a spinning whirl of the type provided with an integral. tube, a straight, fiat, thin piece of steel, which, fastened at one of its ends to the whirl tube, with its free end extending downwardly in alinement with the tube into a shallow depression in the whirl, exerts no independent pressure, but is pressed outwardly against the inner wall of the bobbin wholly by centrifugal force, and thereby holds a bobbin in operative position upon the whirl, substantially as described.

WILLIAM ST. PETER.
