SPECIFICATION forming part of Letters Patent No. 547,980, dated October 15, 1895.

' Appunti@ inea May s1, 1895. serrant. 551,133. (Neuman.)

To @ZZ whom, t may concern: Be it known that I, CHARLES BOULAY, a citizen of the United States, and a resident of Barre, county of Worcester, and State of Mas- 5 sachusetts, have invented certain new and useful Improvements in Machines for Upset-y ting Wagon-Tires, of which the following Ais a speciiication, reference being had to thezac-v companying drawings, forming a part thereof, 1o in which similar letters and figures of reference indicate corresponding parts.

My invention relates to machines for upsetting wagon-tires, and is an improvement on the construction 'shown and described in 15 United States Patent No. 535,481, granted to me March l2, 1895.

The obj ect of the'present invention is to produce means by which the mechanism covered by my patent referred to may bemore easily zo operated and be more simple and effective in its construction and operation.

The invention is fully disclosed in the following specication, of which the accompanying drawings form a part, in which-h 25 Figure lis a side elevation of my improved machine; Fig. 2, a similar view showing the operating parts in different positions, and Fig. 3 avertical transverse section on the line 2 2 of Fig. 1.

My invention relates especially to machines for automatically clamping a wagon-tire and upsetting the same while the metal is hot, the object being to overcome the objections incident to the ordinary methods of upsetting 3 5 tires, where the metal is liable to cool while the tire is being clamped.

The nature and operation of the machine, Atogether with that of the improvements and the advantages secured by the latter, will be 4o readily understood by all conversant with such devices from the following description, when taken in connection with the accompanying drawings.

In the practice of my invention I providea 45 body A for the machine, which consists of a plate having a reinforced or thickened edge 50, said body portion being approximately triangular in section. An arm B is pivoted at cl to the apex or extreme upper portion of the 5o body A and is adapted to swing laterally to and from said body, and ou the lower end of the body portion there is an arc-shaped or segmental lug q, curved or formed on a circle of which the pivot d of the arm B is the center. The arm B has formed thereon near its lower end a similar curved flange or lug r, lying in or forming an arc of the same circle andregistering with the flange or lug q when the parts are in the normal position,and projecting downwardly from said flange or lug r the arm B is provided with an extension or lug D.

On the lower end of the body A, and preferably at the right-hand side thereof, isa lug or extension m, with which is pivotally connected a vertically-swinging forked or divided arm k, said arm being adapted to inclose between the sides thereof the lug or extension D on the arm B,in which is formeda slot D', through which is passed a pin D2, secured to the sides of the arm k, and in the free ends of said arm a lever O is pivoted at J, the end of said lever adjacent to the pivotal connection being provided with a segmental gear g, which meshes with a similar gear or teeth 1I on the outer edge of the extension or lug D.

, Pivoted in suitable bearing 15 on the arm B is a cam or dog w, and on the lower end of the body or thickened side 5() of the body A is pivoted a similar cam or dog to2, said dogs being designed to clamp the tire H against the segmental flanges or lugs fr and q, respectively, as hereinafter described. A sliding bar or plate 17 is fitted to move vertically in a suitable slot in the body A and bears on its lower end a clamping-shoe 16 on the front of the body A, the lower surface of which shoe is serrated or provided with teeth or projections, as shown, by which it is enabled to more securely grasp and hold the tire, and at the rear of the body A a bar 25 is connected with the sliding bar 17 by set-screws 27, and a coilspring 26 connects the lower end of the bar 25 with the body and acts contractivel'y to pull said bar downwardly, as will be readily understood. A cam-lever t is pivoted at 30 to the rear face of the body A, its outer end projecting beyond the arm B in position to be en` gaged by a roller ton the lever O, and the inner end of the cam-lever projects into a socket 28 (shown in Fig. 3) in the slidingbar 25. A lever e' has one end pivoted in lugs y on the IOO dog w, its opposite end being slotted at 22 to receive a pivot on the lng or bar 19 on the slide 17, said slot being designed to permit of slight lost motion, as will be hereinafter described. A coil-spring 18 is interposed between a shoulder on the lever ,e and said lug, and a similar lever 20 pivotally connects the other end of the lug or bar 19 on the slide 17 with lugs :l: on the dog wz.

Near the apex of the body, on the arm B, there is a spring-catch f for the lever C. When the parts are in the position shown in Fig. 1, the leve'r C is forced from the left to the right, as shown in said ligure, until it is engaged and held by the spring-catch j', in which operation the roller t, contacting with the cam-lever o, forces the outer end of said cam-lever downward, and the inner end there of being simultaneously lifted carries the slide 17 upward, thus drawing the clampingslioe 16 away from the body or flange q, and by means of the connecting-lever z and 20 also drawing the dogs w and 102 out ofV contact with the flange r and said body or flange q, and sufficient space is thus formed between the clamp-shoe and dogs and the body or anges r and q to admit the tire H. The lever C being released from the catch f, a spring 2G draws slide 17 downward, engages the shoe' 16 with the tire, and simultaneausly spreads the dogs w and w2into contact with said tire, securely clamping the same against the two flanges r and q. In the further opera-tion of the devices the leverC is thrown outward by the operator, which causes the forked arm la to be thrown or pressed downward, as shown in Fig. 2, while simultaneously therewith the gear g of said lever throws the arm B inward on its pivot d, the pin D2 on said arm, working in the slot D of the lug D, guiding the same, so that the flange r is crowded against the tire, which is tightly held by the clamps, thus upsetting the same and contracting the diameter thereof at this point, as will be readily understood by all those familiar with this class of machines and the method of operating the same.

The slot 22 of the connectinglever z per mits of the above described movement without operating the slide 17, as will be readily understood.

It will be seen that by the use of my device after the lever C is caught by the springf, elevating the clamping dogs and shoes one continuous outward movement of said lever effects the secure clamping of the heated tire in the machine and the upsetting thereof, the operation being so rapid that the metal has no opportunity for cooling.

Pivotally connected with the rear side of the body of the machine or plate A, as shown in dotted lines at A', Fig. 1, isafoot-operated lever A2, having its upward end outwardly curved, as shown at a', adjacent to the springcatchy, said lever being designed to operate the springfto release thelever C, as hereinment is to prevent the hulling, swelling, oi"

twisting of the tire, and make sure the upsetting thereof at a single movement before it has time to cool, and this the shoe will do without exerting great pressure thereon, while the slot D in the extension D provides for a more secure connection of the arm 7c, therewith and a more positive action of the connected parts.

Having fully described my invention, its

construction and operation, I claim and desire to secure by Letters Patent- 1. In a machine for upsetting wagon-tires, theicombination with a body portion provided with a segmental base, of a similar segmental vportion pivoted to said body, a spring-tensioned clamp for securing the tire to said segmental base, a lever and connecting mechanism for actuating said pivoted segment consisting of an arm pivotally connected with one side/of t-he body ot' the machine and provided with a pin Which passes through aslot formed in the extension or lng connected with said pivoted segment, said lever being also pivotally connected with the free end of said arm and provided with a segmental gear which meshes with the corresponding gear formed en said lug or extension of the pivoted segment, substantially as shown and described.

2. In a machine for upsetting wagon-tires, the combination with the body portion provided with asegmental base, of a corresponding segmental portion pivotally connected with said body, spring-tensioned dogs on the body and pivoted segment for clamping the tire thereto, a lever pivotally connected with said body for actuating said pivoted segment, said lever being pivotally connected with an arm which is pivotally connected with the body of the machine,` provided with apin operating in a slot formed in an extension of the pivoted segment, said lever being also provided with a segmental gear which operates in connection with a correspondinggear formed on said extension, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 14th day of May, 1895.

CHARLES BOULAY.
