UNITED STATES CHARLES TAYLOR SWAFFIELD, OF ELKHART, INDIANA.

CLAN: P.

SPECIFICATION forming part of Letters Patent N o. 692,381', dated February 4, 1902.

Applicant nea May 6,1901. sean No. 58,986. ma monti To-avll whom t may concern:

Beit known that LCHARLES TAYLORSWAF- FIELD, a citizen of the United States, residing at Elkhart, Indiana, have invented'certain' new and useful Improvements in Clamps, of which the following is a specification,

My said invention relates to improvements in clamps designed more especially for clamping the axles of vehicles to the axle-bed While the glue is hardening; and the object of the invention is to provide an extremely simple form of clamp capable of being produced at a low cost and one-that is strong, durable, and eiective. I have also aimed to prov. le a frame of such shape that it will readily pass over the collar on the `end of the axle and a shoe or foot so constructed as to enable it to be used at any point along the axle or at the A end of the axle-bed. I have further aimed to provide an improved connection between the compressing-screw and the foot or shoe.

The invention is illustrated vin the accompanying drawings, in 'Which- Figure 1 is a side elevation of the improved clamp. Fig. 2 is a` view at right angles tol Fig. l, showing the clamp applied to the axle and axle-bed. Fig. 3 is a detail showing the preferred manner of connecting the member j C and compressing-screw. 4 Fig. 3 is a similar view of a modification, and Figs.. 4t and 5 are detail views showing aV modiied form of shoe. l

In the drawings, A indicates the frame of the clamp, having for the major portion of its length the parallel portions A'. At its lower end itis widened out into circular form, as shown at A", forming -a rounded-seat for the axle and also providing an enlarged portion capable of slipping over the collar cn the axle.

B represents the foot, having a pivoted connection with a member C, which in its-turn is connected with the compression-screw D, threaded through the upper end of the loop or frame and provided with an operatinghandle D', preferably formed integral with -the screw. The connecting member C has a tubular socket in its upper end to receive the plain cylindrical lower end d of'the screw, and I prefer to hold the connecting member to the screw by slitting the upper edge of the member, as indicated at d', to facilitate its lbeing forced into a corresponding annular groove, as clearly shown in Fig. 3. In lien of connecting the member C to the screw in this manner `I may provide a set-screw d2, having a plain portion d3 passing axially through the lower portion of the member and having a threaded portion engaging a threaded opening in the end of the screw.

The connecting member is provided with cylindrical ears C', which engage bearings in the foot or shoe. These are formed by ears b b on the upper side of the shoe, Whichare swaged or bent over around the ears C', thns forming a simple and effective connection and one which permits rocking oi-theshoe or I foot. l f

The 'central portion of the under face of the shoe is curved, as at B', to permit it to straddle the collar on the axle when used at this point, and one end B2 is preferably plain for bearing on the portion of the axle which eX- tends beyond the collar. The other end has an under face curved at right angles to the curve B' to fit the upper face of the axle-hed and a nabbet b' may be provided. l

Instead of the form o shoe just described I may provide a plain shoe, as shown in Figs. 4 and 5, having a face curved throughout its entire extent, this form being really better adapted for use at point's'other than at the end of-the axle-bed. .Y v Having thus described my invention, what IV claim is l. A clamp. for
