IMPROVED VMACHIN'IEI FOR 'UPSETTING- TIRES, AXLE-TRBES, 8cc.

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

To all whom it'fmay concern Be it known that I, ORLANDO PATEE, of Ypsilanti, in the county of Vashtenaw, and State of Michigan, have invented a new and improved Machine for Upsetting Tires, Axle-Trees, 85e.; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation, the wall or frame ofthe machine heilig removed in tln'ee places, and the interior parts at those points shown in section.

Figure 2 is a plan, the floor or platform of the machine being broken away in several places for a similar purpose.

The object of this invention is to vconstruct a machine for the purpose of upsetting tires, 83e., which shall operate eiiectively, and with greater convenience than any heretofore employed.

To this end the eccentrics that hold the tire are al made to be operated by the movement of a single' venient manner.

In connection with this improved construction and arrangement of the parts referred to, a new and improved method of constructing the eccentrics is employed, whereby they are rendered much cheaper and more durable than heretofore.

In the drawings- A represents the frame of the machine;

- B B', the clamps that hold the`tire or other article, one of them screwing toward and -from the other, by means ofa bami-screw, I);

C C, the boxes, which cover and'protcct all but the faces of the eccentrics, each box. having a removable cover, O, held in place by buttons c c; v

D D, the four eccentrics, which take hold of the ends of the tire, or other metallic article, and compress it longitudinally;

E, aplatform, supporting two of the eccentrics D D2, and the clamps B B', and capable of sliding longitudinally by the operation of a lever, L;

F, another platform, support-ing the other twoeccentri'cs D D3, and likewise sliding longitudinally by the action ofthe lever I.; and

G, a shalt, covered and concealed bya box orhonsing, H, and capable of being rocked by lever or levers L L Ihe function of shaft G is twofold: first, by means of an eccentric, g, to give a reciprocating motion to a bar, I; and secondly, to give a similar motion to plat- -form E, throwing said platform to the left (tig. l) when the handle of lever L is thrown to the left, by means of a shoulder, t', which strikes against the end of the platform, and dra-wing said platform to the right again, when said handle is thrown to the right by means of hooks h h, attached to the platform, and ratchet-teeth a a, on the ends of the shaft, adjacent to levers L L.

It will b e here observed that the lever, as it is rocked,

4nearer to platform kE, and be fixed in that position,

while, every throw of said lever to the right, it shall move toward the right, together with the platform E. In other words, every throw of the handle of lever L to the right, (tig. 1,) slides both platforms F and Etoward the right, while during every movement of said handle to the left, platform F remains xed, and platform E moves to the left towards it, thus bringing the two platforms nearer together, and upsetting the/tire, or other article held by the clamps B B'.

I will now more particularly describe themechzm-- ism by which this is effected.

The har I extends the whole length of the machine,.

and under the platform F, has a transverse notch or gain on its upper side, through which works a sliding wedge., fm, actuated by a weight, IV, the -wedge being held in connection with platform F, by means of a guide-groove, o, and a spur upon the under side of the platform, projecting into the groove. v

As the bar is forced toward the left, (fig. 1,) the weight draws the wedge into the slot in it, and thus fixes them' in that new position with relation to platform F.

Now, when the lever is thrown to the right again, it carries bar I and platform F both to the right with it, and, as it does so, another wedge, n, actuated inthe opposite direction by a weight, W, slides into a gain in the under side of platform F, and between the shoulder of such gain and a rigid part, a', of frame A, and holds platform F in the new position with relation to the frame In other words, the two wedges act as choclts.

When, by the left throw of the lever, platform E is moved toward platform F, wedge m slides into the gain in bar I, and chocks the two platforms in that posi# tion; and when, by the right throw of the lever, platforms E and I are moved to the right, wedge n slides into` the gain on the under side of platform F, and

lof chains 7.', withdraw the wedges from the slots or E F, that when the levers K K are" depressed to a con' siderable distance, so as to withdraw thewedges m n, ,then the action of the levers K K upon the bent part p', will move the levers N N, and thereby draw the platform F away from the platform E.

O is a link-or bent rod articulated to the sides of platform F, at f', and provided with a shoulder, o', which, when this platform is drawn away from the other, to the proper point, falls by its own weight, and locks over thetbeam a', so as to hold' the platform in that position, but which is itself thrown up, and unlocked by the action of a cam, i, on the bar I, at the first movement of lever L to the left, the inclined side ofthe cam'striking under the shoulder o, raising vthe latter above the beam a, and libelating the platform.

d d are the vertical shafts of the four eccentrics D T, a treadle articulated to the end of the block It,-

as shown at .t, in such a manner, thatby depressing the outer end of the treadle, the block will `be rocked on its pivot, the springs thrown down, and the eceen trios D Dl turned on their vertical axis, and caused to grapple the tire, axle-tree, 85o., and hold it firmly during the movement of the two platforms by the `lever L, as above described.

The construction of the eccentrics DDl D2 D3 is a matterof some importance. If made of steel, they are unnecessarily expensive, and if made of iron, they become pressed out of shape themselves, and have to be often renewed. I, therefore, make the body ofthem, as shown by the lines e e, of iron. Into one side of the iron part, I insert a corrugated `steel facing, c, fixing it in place by means of 'a dovetail, fur', and, if necessary, bolts yor screws c.

The operation of the machine is simple and convenient.

As soon 4as one tire, axle-tree, or other article is upset, 'the Voperator removes his foot from treadle T, thus' releasing `the eccentrics D D' D'l D. H e then unscrews the part b, and removes the tire, shown in red lilies, fig. 2. Next, he goes round to the other end of the machine, and presses his foot on` treadle M, which removes the wedges from their gains, and at the same time draws platform F to the left until the hook o', 'on bent bar-O, drops overthe beam a', and locks the platform in that position. He then throws thehandle of lever L to the right as 'far as it will go, separating the jaws D vD3 from the jaws D D2 as far as possible, after which 'he' inserts the new tire, or other article to be upset, clamps it by a movement of screw b, and brings all the eccentric gripers D DD2 D3 to bear upon it by a sngle'downward movement of treadle T. He is now-'ready to operate lever L, the first movement of which t o` the left, throws up h tr O,- and releases platform F, and at the same time pushes platform E to the left,` partially upsetting the tire, &c.

The return movement of the lever draws back platform E, and with itplatform- F,and wedge n slides behind the latter, preventing it from losing the ground thus gained.

The next `movement of lever L to the left, further advances the process of upsetting the tire, and the operation is thus continued until the tire is fully upset, or until it becomes necessary to adjust it again in the 'eccentric-jaws'and repeat the process.

Having thus described my invention, v What I claim as new, and desire to secure by 'Letters Patent, is-

1.l The combination of platforms E F with har I,

`wedges 'nt 11*eccentric shaft G, lever L, and hooks hh,

all constructed 'to operate substantially as and for the purpose set forth. i

2. Connecting the wedge m to the platform F by means of the slot o and the spur of the platform projecting into it, when the parts referred to are constructed and operated as and for the purpose set forth. 3. Operating simultaneously all the eccentrics D Dl Dz D3 `ofan upsetting-machine, by means of the parts Q S It T, substantially as and for` the purposes described.

4. The hooked link or bar O, when constructed to operate in connection with platform F, bar I, beam ai', and cam t', substantially as and for the purposes described.

5. The combination of weighted treadle M, with weighted leversK K, chains la k, wedges A11i-)aand weights XV W', substantially as and for the purposes set forth. 6. In combination with the parts M K K la k m n W W', the bent levers N N, constructed ito operate in connection with platform F, as described.
