IMPROVEMENT IN TIRE-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, SAMUEL. Ron, Jr., ofBoonville, county of Cooper, State 'of Missouri, have invented a new and usefullmprovement in Tire-Shrinkers, of which the following is a full, clear, and exact description, reference being had to the'accompanying drawing making part of this specification, in whichh l -igure 1 is a perspective view of my improved mac me.

Figure 2 represents the operating-lever.

My invention relates to a novel construction of the operating-lever of atire-shrinker, and a new arrangement of parts, whereby certain advantages are obtained, as will be fully explained.

In the drawing A A A A are the posts, of which each pair are connected, at their upper ends, by the girts B B, substantially in the manner shown in the drawingi Each of these girts is provided upon its innervertical face with a longitudinal groove extending from end to end.

In the drawing these girts are represented as being composed of two parts, the lower'one of which is formed inone piece with the legs or posts A A, the

upper one being rebated upon its lower inner edge, said rebate forming, in combination with the lower part, the groove or way above referred to.

The lower lips or flanges of these grooves'are wider than the upper ones are, and project further in'toward the center, thus making the space between the lower flanges at b narrower than the space between the up per ones at I), (see fig. 1,) for a purpose which will hereinafter be explained.

G C are clamps, each provided with upright ears orlngs at such distance apart as will admit of a wagontire being readily placed between them.

a c are small blocks, made preferably of steel and harddened. The upper faces of these blocks are serrate e D D are wedge-shaped keys, fitting perforations or sockets in the upright ears of clamps (J C.

The clamps O C are provided with wings or flanges, 0, adapted to fit closely and more freely in the grooves in the girts B B.

The clamp C is rigidly'seoured in position at one end of girts B B, while the clamp G'is free to slide in the groove when actuated by devices which will be presently described.

E is a forked lever, the upper arm 0 being expanded to a width about equal to the width of clamp O.

The lever E is connected with the stationary clamp (l by means of a pivoted link or links, E, substantially asshown in the drawing, the length of these links being such that when the parts are in working position, as shown in the drawing, the clamp O abuts against the broad end c of lever E.

F is a spring, the free end of which rests against the inner side of clamp G.

The lever is confined to the body of the clamp by the machine'is readyto repeat the operation.

, It will be seen that by my manner of arranging the lever and connecting-links the power is applied directly tothe clamps and the frame-Work relieved of all strain, and also that by making the upper arm of v the forked lever of greater width than the space be tween the lower flanges of the girtsB B, these flanges are made to form a support, upon which the inner end.

of the lever rests in a convenient position for operating.

When preferred the girts B B may be made of one piece each, and grooved by machinery or otherwise.

It will be seen that as lever B is pivoted to the free ends of links IE it (the lever) is movable vertically, and can be adjusted relative to the clamp 0., against'which the end e bears, and hence can be so applied as to operate the clamp with but little or no friction upon the ways, or of the end 0 upon the face of the clamp, while at the same time the lever is practically adjustable relative to clamp O G, as follows: I I

It sometimes happens that a single sweep of the lever will not shorten a the quite as much as is desired, and in such a case I can withdraw the lever a little, and, by inserting a suitable block between the end a and the clamp, still further shrink it, the inserted block serving as a gauge to indicate the amount of this shrinkage.

The expanded'end e serves not only to form a wide bearing upon the clamp, but also to support the inner end of the lever upon the flanges I), thus keeping it (the lever) always in a convenient position forwork- Having now described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The combination of the clamps O 0, links F, lever B, ways B B, and spring F, all constructed and operating as described.

In testimony whereof I have hereunto set my hand this 6th day of August, A. D. 1870.
