%OBERT E. ALEXANDER, OF NIAGARA, PENNSLVANIA.
MACHINE FOR UPSETTING AND STRETCHING TIRES.
SECIFICATION forming part of Letters Patent No. 256,'944, dated Apri125, 1882.
Application filed November 19, 1881. (Model) To all 'whom tt may conccrn:
Be it known that I, ROBERT E. ALEXANDER of N iagara, in the county of Wayne and State of Pennsylvania, have invented certain new and useful Improvements in Tire-Upsetters; and I do hereby declare that the following is a full, clear, and exact description ofthe same.
My invention relates to instruments of the class known as tire-upsetters, intended particularly for stretching and upsettin g wagon-tircs when found too short or too long, so as to make them fit the fellies; and my invention consists in the combination, with a bed-piece, of a pair of oppositely-sliding bars, and a lever for simultaneously noving said bars in opposite directions, and a pair of pivoted adj ustable tireholders, all as will be more fully hereinafter described.
In the drawings, Figure 1 is a plan view with the lever shown in dotted lines. Fig. 2 is a section on line :v x of Fig. 1. Fig. 3 is an edge view, showing the nanuer of attaching the tire-holder or vise.
In these drawings, A represents a flat Inetallic bed-piece, slightly cnrved fI`OIIl end to end, and having` a central orifice to receive a bolt. Longitudinal dovetail grooves B B extend from each end of the bed-piece near] y to the central opening, and in these dovetail grooves slide bars C C, of aferm in cross-section to snugly fit the grooves and work smoothly therein. The grooves and bars are formed on the same curve as the bed-piece. Near the inner end of each bar C is a short pin, 2, and these pins are so placed that they fit in cnrved grooves 3 4 in the lower face of a lever, D, when such lever is placed in position upon the central bolt, 1. Motion of the lever in either direction will move the bars either outward or inward, as the ease may be, but always in opposite directions. The lever is secured upon the bolt by a nut, 5. The tire is carried by holders or vises E E. The end of each of the bars CC isbored out, as shown, and theholder E is attached thereto by means of ears 7 7 and a bolt, 8. The ears are rigidly attached to a sliding jaw, 9, which slides upon the shanl: 10 of a fixed jaw, ll. The continuation of the shank 10 is threaded, as at 12, and carries a grip orhandle, F, having an interier thread, by means of which the handle may be advanced or retracted along the screw-shank. Thelower end of the novablejaw') has a projection, 13, against which the fiat inner end ot' the handle beats, forcing the movable jaw toward -the fixed face. The device is thus adapted to different thicknesses of tire.
In the operation ot' this implement the tire, previously heated, is placed on the holders be tween the jaws, so that it bears against the flat lower face of the bed-piece. Power is then applied to the lever, and the arms or bars moved outward, causing the metal to stretch. By turning in the opposite direction the metal will be caused to shrink.
My implement is a compact and powerful one, ot'simple Construction, and very effective for the purpose for which it is intended.
Having thus described my invention, what I claim is-- In combination with the sliding bars and operatinglever, the tire-holders pivoted to such slidingbars, and having the fixedjaw, the movable jaw, the threaded shank, and the screw grip or handle, all substantially as described.
In testimony whereof I have hereunto signed my name, in the presence of two witnesses, this 5th day of November, 1881.
ROBERT E. ALEXANDER.
