Nrrnn STATES PATENT IMPROVEMENT IN ATTACHMENTS FOR WHIP-PLATTINIG MACHINES.

Specicat-ion forming part of Letters Patent No. 180,026, dated July 18, 1876; application filed February 23,1816.

cation, and to the letters of reference marked thereon.

The object of my invention is to provide a means of holding a whip iirmly at the butt while it is being platted, and at the same time to permit it to pass upward freely, and, when the platting is finished, to have the whip released from its fastening automatically.

To this end my invention consists ot' a carriage having two jaws, and sliding up and down in vertical ways or guides, which jawsl grasp and hold the butt of the whip irmly, passing upward while the whi p is being platted, a projection upon the u pward-movin g carriage operating to trip -a spring-catch, releasing' a spring-presser, which opens the jaws and releases the finished whip, and also holds the carriage stationary while another whip-butt is inserted in the jaws, which, with the carriage, is then moved down, the presser and catch being released for that purpose, as will be more fully hereinafter described.

Figure I represents a perspective view of the device with the carriage and jaws lowered to commence the platting of a whip. Fig. II represents the same device with the jaws and carriage elevated, and the jaws opened to release the finished whip; and Fig. III is a side View of the spring presser and catch, which prevents the carriage from falling while the presser is holding the jaws open.

In the drawing, A A represent the upright ways or guides, which may be secured firmly together by braces A'. Arranged to slide freely up and down in these ways is the carriage B, having a permanent jaw, a, made thereon, with a movable jaw, a', made upon the upper end of the lever D, which is pivoted to the carriage at b; and a spring, b', bearing between the lower arm of saidv lever and the carriage, operates to keep the jaws always closed.

To the bridge (l is secured a spring, E, up-

on the lower end of which is a presser, e, which presser e along the inclinedlower surface of the catch I, and outside of its shoulder o, where it is held, as shown in Fig. I, and the jaws and carriage B immediately drop to the lower end of the ways, in the position shown in Fig. I.

The whole device being attached to a whip- I platting machine, the latter is then set in motion, with the ordinary weight attached to the upper end of the whip, the jaws below griping firmly its lower end or butt. As the platting proceeds, the whip, carriage, and jaws move up at the proper speed, and when the carriage and jaws reach the top of the ways or guides a projection, i, upon the carriagey presses up against the catch I, forcing. it up sufficiently to permit the presser e to move in quickly, pressing against the lever D, and opening the jaws and releasing the butt therefrom 5 and at the same time a projection, a, upon the presser moves in beneath the projection t of the carria-ge, or beneath the carriage itself, to prevent the latter from falling, and to hold it in its elevated position while a new whip-butt is" being inserted between the jaws. The platted whip having been removed, another whip-butt is inserted in the jaws, .and the lever Gr pressed in to move out and secure the presser e, and to permit the carriage and jaws to drop as before, and the operation of platting the newlyinserted whip proceeds.

It will be perceived that the releasing of thel platted whi p is entirely automatic, and the whip, While being platted, being held at both ends, is held much more firmly, andin a fixed vertical position, than by any other means now practiced.

The projection n upon the presser is not, in itself, an essential feature in the invention, as

Ferca.

, it is evident that the presser may be made to press against the lever D With sucient force to hold the carriage up while inserting the butt.

The lever G, instead of being pivoted to the braces I-I at a point below the presser, may be pivoted to the bar C at a point above the presser, if it should be desired, in practice, to llave the lever nearer the upper end of the device to facilitate its operation.

Having thus described my invention, what I claim as new is l. The guides A and the carriage B,pro vided with jaws a a', closed by a spring and moving in said guides, in combination with a spring-presser, e, and spring-catch I, whereby a whip, when being platted, is automatically released from the attachment as soon as the platting is completed, scribed.

2. The combination of the spring-presser e, the spring-catch I, and the lever G, pivoted to said presser, whereby `the carriage B is resubstantially as devleased from its elevated position and permit-
