UNITED STATES PATENT Einen.

CHARLES M. COMSTOCK, OF WINDSOR, NEW YORK.

WHIP-CORE.

SPECIFICATION forming part of Letters Patent No. 393,691, dated November 27, 1888.

Application filed May 7, 1888. Serial No. 273,089. (No model.)

T o al? whom it may concern:

Be itk nown that I, CHARLES M. CoMsTooK, a citizen ofthe United States, residing at Windsor, in the county of Broome and State of New York,have invented certain new and useful Improvements in Whip-Cores, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Similarletters refer to similar parts throughout the several views.

My invention relates to improvements in the center or core for whips, the object being to provide a core embodying in its construction weight and flexibility, and which will not break under any ordinary usage, nor break loose from the siding which is put ou to give the whip the desired size and shape.

Carriage-whips have usually been made by using a strip of whalebone for the core, then gluing or cementing the rattan siding on the whalebone to give it proper size, then tapering and rounding the siding before covering.

It has been desirable for a long time to discover some material which could be used for the center of whips as a substitute for whalebone, as the increasing demand for whips and the decreasing supply of whalebone render it very difficult to procure the needed material; and the object of this invention is to supply this want.

My invention consists of a core of uniform diameter throughout its length and formed of coiled wire, the coils of which are wound substantiall y close against each other with a strip of rawhide or like flexible and nonelastic material folded around and adhering to it to prevent the convolutions ofthe wire center from spreading apart when the whip is put to severe usage.

In the accompanying drawings, Figure l shows a part of the core as completed and ready for the siding, except that at the upper end the covering is open to show the center wire. Fig. 2 is a longitudinal section' cut through the center of the whip, showing the vwithout increasing the size of the core at the lap. Fig. 4 shows the naked wire cable used for the center. Fig. 5 is a cross-section of the core when completed and ready for the siding. All these views are enlarged beyond their ordinary size in order that they may be more plainly shown.

I have not deemed it necessary to furnish drawings of the completed whip, as every one familiar with the art will know how the additional parts of the whip are supplied, and I only illustrate the core, which is all I claim as new.

The center coil, B,is made,preferably, of tempered steel wire,and thecoilmustbewound substantiall y close upon itself. Upon this coil,cut of a proper length forthewhip,is the covering A, of rawhide or similar fiexible non-elastic material,put on when moist and soft and rolled Y down firmly on the wire coil. It is then wound with thread to hold it close down on the wire and is laid aside to dry. This shrinks it down firmly upon the wire and makes them substantially one. When the cover is thoroughly dried,the thread is taken off, and on the rawhide cover the rattan sidings in ordinary use can be applied by the same means and methods as heretofore in use when applied to whalebone and other cores. It is obvious that by means of this cover pressed down into the coils of the wire the tendency of the coil to expand under strain is entirely counteraeted, as each turn of the wire is held close in its place,while the iiexibility of the coil is not substantially impaired by the cover. rlhe spring of the wire keeps the whip up in shape and prevents it from becoming soft and lifeless, as it will whenvmade upon a rawhide center without the wire coil.

. I have so far only used rawhide for the covering of the coil, and think it preferable to any other known material for this use, but do not wish to limit myself toits use, as any adhesive, iiexible, non-elastic substance adhering closely to the wire, bending easily with it,and not extending under the strain of a blow will answer the same purpose as the rawhide.

IOO

I am aware that a patent has been granted for a core for whips formed of metal having a thread wound spirally around it and a siding adhering closely to it. This construction is, however, very different from and milch inferior to my core in many Obvious respects. I um also aware that cores have been formed of spirally-wound metallic ribbons or strips tapered from end to end. This latter construction has been found from practical experience to bc useless, by reason of the fact that when a blow is struck with a whip thus constructed the convolutions ofthe coil are extended, and the coil is broken 'loose from the siding, and, furthermore, a metal ribbon or strip will cut any cover in a very short space oftimc and ruin the whip. It has been shown from practical experience that a whip consti-noted after the plan herein set forth is not subject to the disadvantages above set forth, and that the only coil which can be successfully used is a wire coil of uniform size.

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

A whip core or center of uniform diameter throughout its length, and consisting of a closely-wonnd coil of wire and a covering of flexible non-elastic material adhering,r closely to the said Coil.
