SPECIAL ADMINISTRATOR, OF CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE STANDARD PARTS TION OF OHIO.

COMPANY, OF CLEVELAND, OHIO, A. CORPORA- MACHINE FOR FORMING TRANSSPLIT RIMS.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed February 16, 1916. Serial N 0. 78,667.

To all whom it may concern Be it known that I, OTTo H. JoBsKI, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, special administrator of the estate of RICHARDS. BRYANT, deceased, late a citizen of the United States, and resident of Cleveland Ohio, (as by reference to the duly certified copy of letters of administration heretofore filed for the purpose of record will more fully appear,) believe said RICHARD S. BRYANT to have invented a new and useful Improvement in Machines for Forming Transsplit Rims, of which the following is a' specification, the principle of the invention being herein explained and the best mode in which it was contemplated applying said principle, so as to distinguish it from other inventions.

The present improvements relate to a machine for forming annular bands, such as vehicle-wheel rims comprising means for re-- ceiving straight stock and bending or circling the same into a split annulus of the desired diameter and curvature. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may \be used.

In said annexed drawings 2- Figure 1 is a side elevation of a machine embodying my present improvements and more particularly showing the forming rolls; Fig. 1 is a perspective view of a detail of such machine; Fig. 2 is a front View of the same; Fig. '3 is a partial view, on an enlarged scale, showing the adjustable guide rolls for varying the curvature given to the stock and Fig. 4 is a plan view of one of the guide rolls.

The general character of the machine may best be seenfrom Fig. 1, there being the usual frame 1' on which are mounted two parallel horizontally disposed shafts 2 and 3 which will be drivenin any suitable manner at the same rotative speed (driving means not shown). The machine is similar in its general construction to the ordinary flange rolling machine for use in forming the flanges on stock to be later bent up into rims, and hence the details of the construction of the machine need not be gone into except so far as additions have been made to it for carrying out the present operations.

In Fig. 2 there are shown rolls 4 and 5 through which the stock is delivered to the circling mechanism or is flanged and delivered as may be desired, these rolls then delivering the straight or flanged stock between rolls 6 and 7, mounted on the shafts 2 and 3 respectively. It will be noticed that the two shafts 2 and 3 are not in vertical alinement, the upper shaft 2 being slightly nearer to the feeding rolls 5, and thus the stock when passed between these two rolls is bent upward and as it is fed forward it is moved around the upper :roll 6. In order to secure the desired radius of curvature on this bent-up stock, and to cause the same to be circled into a perfect annulus, there are provided adjustable guide rolls 8 and 9 on either side of the rolls 6, each of these rolls 8 and 9 being mounted on a short shaft or pin 1.0 which is held in the ends of two rods 11 and 12. Each of these two rods is adjustably received in a block 13 which is pivotally mounted about stub shafts 14. Each of the rolls can therefore be adjusted with respect to the rolls 6 in both a horizontal and vertical direction, and thus can be given the exact position which is required to produce any desiredradius of curvature on the bent tation of the stock between the forming rolls thus discharges the rim at the front of the machine from which it is removed by an 0perator. By thus causing the stock to be automatically removed the machine may be operated continuously, since the bands fall in front of the machine and do not interfere with the incoming stock, nor do they require the attention of the operator,

The roll 7 is placed at a) fixed level, but the roll 6 can be adjusted vertically into co operative position on the roll 7 since the shaft 2 is adjustably mounted in supports 18 by means of the threaded bolts 19. In Fig. 2, as also in Fig. 3, the position of the stock in the rolls is illustrated in dotted outline, showing not only the manner in which 1t is circled, but also, in the case of said Fig. 2, the manner in which the free end thereof strikes the plate '16 so as to cause the discharge of the completely circled rim as soon as the other end is released from the rolls. This roll 6 will of course be positioned with respect to the roll 7 at the beginning of the work, and will not need to be again positioned until the size of the stock is varied. The rolls 6 and 7 are of course formed to correspond to the shape given the stock when passing through the forming rolls 4 and 5; that is, these rolls are provided with beveled edges corresponding to the flanges which have been formed upon the stock.

' Other modes of applying the principle ofmy invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

It is therefore particularly pointed out and distinctly claimed as the invention 1. In a machine for forming trans-split rims, the combination of cooperative forming rolls for bending the unformed stock,

an initial guide roll mounted in advance of 1916 said cooperative forming rolls, two rods adjustably mounted in blocks on said machine, a stub shaft mounted in the ends of said two rods and a guide roller on said shaft at the rear of said forming rolls.

2. In a machine for forming trans-split rims, the combination of cooperative form 3 In a machine for forming trans-split rims, the combination of cooperative forming rolls for bending the unformed stock,

guide rollers mounted in advance and to the rear of said forming rolls, said roller being capable of movement in the plane of said forming rolls and comprising two blocks pivotally attached to the machine, two rods threaded into said blocks, a stub shaft carried by the outer ends of said rods and a guide roll mounted on said shaft.

4. In a machine for forming trans-split rims, the combination of cooperative forming rolls for bending the unformed stock, guide rollers mounted in advance and to -the rear of said forming rolls, said rollers be mg capable of movement in the plane of said forming rolls and comprising two blocks pivotally attached to the machine, two rods threaded into said blocks, astub shaft carried by the outer ends of said rods, and'a guide roll mounted on said shaft, and a cam plate adapted to be contacted bythe formed stock to turn the same spirally away from the forming rolls. a
