46 denotes a. pair. of eyebolts rigidly attached to each side of the frame in alinement when saidbeds are in closed position.

47 represents a binding-post securely held in one eyebolt and provided with a series of apertures 48 in vertical alinement each adapted to receive a sto .pin 49. a '50 denotes another binding-post eld in the opposite eyebolt and formed with a series of notches 51 on the upper portion of its length. A binding-bar 52 is formed with a forked head 53, designed to embrace post 47, the curved prongs of the head passing beneath pinr49, positioned in one of the apertures 48. .A clamping-shoe 54 concave on itsunder face is securely attached to bar 52 midway that portion of its length overlying the frame When in operative position. f

55 denotes a locking edge formed integral With-bar 52 and adapted to engage notches 51 when saidbar is forced to binding position.

The operation of the machine is as follows: Assuming the beds to be-in open position, as shown in Fig. 2, the wheel w1th tire. fitted to the folly thereof is set between the four clamping members 22 longitudinally of the frame, the tire resting on flanges 25 of said members and at its lowest point on plate 19.

adjusting-wedge 26 is next inserted beneaththe outerend of each pair of clamping members a sufiicient distance. to cause them to conform to the curvature of the tire being operated upon. By means of inserting a sufficient number of \binding-strips 23 between plates 20 21 and the clamping memberssaid members are now forced toward each other laterally of the frame until they securely gri the tire between their serratededges. Shaft the beds either by means of lever 8 cooperating with cog-wheel 12 through the medium of I I dog 11 or by means of power-wheel 12 and causing gear-wheel'7 to mesh with segment.- gear 35, which inthe above-describedv position of the parts is at or near its lowest point of travel. Continued revolution ofshaft 6 will of course move gear 35 in itsupward path of travel and force beds 13 and 14 to.-

ward each other supported and guided by guide-bars 31 in guideways 32, movement of bed 13- being effected through'cooperation of lug 38 with aperture 30 in bed-plate 29 and movement of bed 14 through the cooperation of link 40 with head 36 of the T-lever. As the beds approach each other. a strenuous pull is exerted on that portion of the tire free from the clamping members from its highest -point downward in both directions along the felly, resulting in tightly binding said por tion of the tire to. its fel while'an equally. strenuous crowding or pushing force is ex ertedtoward is lowest point on that portion ofthe tire gripped by the clamping members, resulting in upsetting the tire at said point in the irection of the felly, the plate '19 effectively overcoming the tendency to upset in the opposite direction and, as obvious, forcing the upset portion into the felly and securely binding the whole tire to the fell liaving thus described the invention, what isvclaimed as new iSr Attire-setting machine com ris ng a mam frame, beds movably mounte mthe frame,

clamping members freely movable on the v beds, a main shaft revolubly supported by the frame, a T-lever connected to and operated by said shaft, one arm of the lever en-. gaging one of the-beds, and a second lever engaging the other bed and connected to the other arm of the T-l ever, whereby in the op eration of the shaft the beds. are reciprocated in relatively opposite directions.
