ATTACHMENT FOR WHlP-PLATTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 248,499, dated October 18, 1881,

Application filed July 8, 1881. (No model.)

To all whom it may concern:

. Be it known that 1, SANFORD A. PENNY, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Attachments for Whip-Platting Machines; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is an elevation of the attachment. Fig. 2 is aplan of the lower portion, looking downward from the section-line m m. Fig. 3 is a plan of the rollers and their connecting parts on an enlarged scale.

My improvement relates to attachments for holding the whip while the external covering is being woven or braided thereon.

The machine used for weaving the covering consists of a ring,which contains the spools of thread and the working parts, and the threads all concentrate to the center, where the weavingis done. Heretofore it has been customary to hold the whip in the center of the ring by means of a clamp and weight at thebottom and a cord attached to the top, which cord passes over a pulley and has a counter-weight attached to its opposite end. This arrangement is attended with many objections; and my invention consists in substituting for the devices above described the following arrangement.

A represents a bed or frame, which is firmly attached on the under side of any suitable supporting part. At one end it has a socket-piece, B, in which rests a tubular socket, 0, having on one side of the bearing a worm-gear, E, and on the other one or more nuts, D. By this means the socket is held to the hearing, but is allowed to rotate freely therein. With the worm-wheel E engages a worm, F, on a horizontal shaft, G, and on the outer end of the shaft are two fixed pulleys, H H, between which slides a shifting pulley, I, operated by a clutch, K. This arrangement constitutes a clutchgear, and by shifting the intermediate pulley from one fixed pulley to the other the motion of the shaft may be reversed at pleasure. The shifting pulley is driven by any suitable means.

L is a hollow tubular vertical shaft, which rests in the socket O, and to which it is made machine and holds the whip, the upper end of the whip being attached to a weighted cord passing over a pulley in the ordinary manner.

M M are two levers, pivoted at b b to the upper end of the tubular holder L. Each lever is encircled by a spiral spring, N, attached to pins 0 c, which has a tendency to draw the lever inward, and the inward motion is checked by a stop, at, at the top of the shaft.

P P are two rollers, pivoted respectively in the tops of the levers M M. double conical form, with the narrowest part in the center, and the roller P is of reverse double conical form, with the widest part in the center, as clearly shown in the plan view, Fig. 3. The roller P is provided with a series of circumferential ribs, ff, over its whole periphery, and at uniform distance apart, while the roller P is provided with a single central groove, f, the object of the ribs and groove being to prevent slipping ot' the whip.

In operation the whip is placed in the tubular shaft L, resting between the rollers P P, as indicated by the dotted lines, and the platting is done by the platting-machine in the usual way, the work being done immediately above but close to the rollers.

By the use of this device the clamp weight and rod ordinarily used at the bottom or the top of the whip are dispensed with. By this means, also,the whipis held much steadier to its work, as allswingin g and swayingare avoided. The platting is done close to the holding con tact of the rollers with the whip, while in the ordinary machine it is far above, and consequently the work is more or less unsteady. The rollers, by their elasticity, close upon all parts of the whip from tip to base, and the ribs and grooves hold it against slipping. A greater variety of configurations of the work can be donethan in the ordinary machine.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The roller P is of 1. The attachment for whip-platting machines, consisting of the tubular holder L, in which the whip rests loosely, said holder receiving rotary motion, and being provided at its top with clamping-rollers 0, which prevent the whip from turning independently, but allow it end movement, as herein shown and described.

2. In an attachment for whip-platting Inachines, the combination, with the tubular holder L,in which the whip rests, of the levers M M, pivoted to the holder, and the friction-rollers P P, pivoted in the tops of the levers and holding the whip, as shown and described, and for the purpose specified.

3. In an attachment for whip-platting inachines, the combination of the tubular holder L, the two levers M M, pivoted thereto, the two clampingrollers P P, pivoted in the ends ofthelevers, and thelwo separate spiral springs N N, encircling the levers above their pivots, as shown and described, and for the purpose specified.

4. In an attachment for whip-platting machines, the combination of the two clampingrollers P P, the first of double-concave form narrowest in the center, the last of double-concave form widest in the center, one fitting into the other, and adapted to hold the whip between them, said rollers being provided with circumferential grooves f f as and for the purpose specified.

5. An attachment to whip-plattin g machines, consisting of the frame A, socket-piece B, socket C, tubular holder L, levers M M, rollers P P, springs N N, and the shaft G, having aworm, F, engaging with worm-wheel E on the socket O, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

SANFORD A. PENNY.
