To vall whom it may concern.'

Be it known that I, HENRY Y. HILDEBRAND, a citizen of the United States, residing in the city of Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Disk-Rolling Machines; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This application is supplementary to my co-pending application tiled September 30, 1919, Serial No. 327,509.

My invention relates rolling suitable blanks into substantially circular disks which have a relatively thick central portion tapering thence to a thinner periphery. These disks are adapted for use in various constructions and particularly for automobile and other vehicle wheels.

The object of a disk rolling able blanks into substantially circular disks, of tapered or reduced form, which are adapted to the uses outlined. Tapered disks have heretofore been made by slow and expensive machine turning, but disks so made do not possess the requisite strength, whereas disks to a machine for formed in my disk rolling machine showar greater strength for equivalent sizes and dimenslons.

My invention comprises apparatus which firmly clamps and holds the central portion of a blank or disk and permits free rotation of the blank or disk as the outer' portion thereof is inserted between a pair of overhang rolls, which are tapered or otherwise shaped to conform to the desired crosssection of the disk. The clamping means may be moved to or from the rolls in the general direction of the roll axes so that the blank or disk or portions thereof are grasped by the rolls, when they are rotatlng, tov thin, taper or otherwise shape the blank or disk and simultaneously to increase the diameter thereof to the re uired degree.y The clamping means may a so be adjusted transversely ofthe rolls so that the axis of rotation of the blank or disk can 'be moved to or from the rolls in the plane my invention is to providey machine that will roll suit' DISK-RQLLING MACHINE. I

Renewed August 8, 1922. Serial No. fktil able thickness and diameter and are preferably circular disks, although they may be of other shapes, if desired.

aving thus given a general description of my invention, I will now, in order to make the mattermore clear, refer to the annexed sheet of drawings in which like characters refer to like parts Figure 1 is a side elevation of my improved disk rolling machine; Figure 2 is a detail, in vertical sectional elevation, of the fluid-pressure operated clamping jaws for holding the blank or disk while it is being` rolled; Figure 3 is an end elevation of my disk rolling machine.; Figure 4 is a vertical longitudinal sectional elevation of thev carriage support and carriage illustrating the attachment of the piston rod and longitudinal bolt thereto; and Figure 5 is a top plan view of the disk holding mechanism. 1

Referring now to the characters of reference on the drawings :-1 is the base of the machine on which the various parts 'are mounted and 2 indicates the rolling mill in general, the rolls 3 and 4 of which are` rame 5 and is provided with a Flange 8 The notch 9 en-Y preferably square shank of the which contains a notch 9. gages the longitudinal bolt 10 which passes through a hole 13 in the Flange 12 of the guide-frame 5 and carries the nut 11. The limit of the forward travel of the carriage 7 may therefore be varied by changing the position of the nut 11 on the bolt 10.

The adjustable frame 24 .is mountedV upon the carriage 7 and is secured thereto by the bolts 23, the'heads of which set in slots 22 in the carriage 7. Set screws 21 in the flanges 2O of the carriage 7 provide means for moving the adjustable frame' 24 and the parts mounted thereon transversely of the roll axes. A journal bearing 30, secured to the adjustable frame 24, carries the lower rotatable clamping jaw 28 which is suplied with cooling fluid through the pipe 31.

he lower clamping jaw 28 is provided with a face-plate 29 in which is secured the centering pin 41. The centering pin 41 engages a central hole in the disk or blank 40 and projects therefrom into the recess 42 inthe face-plate 27 of the upper clamping jaw 26.

The top frame 25 is rigidly mounted upon the adjustable frame 24 and carries a movable Huid-pressure operated and fluid-cooled rotatable clamping jaw 26 to which is secured a face-plate 27. This upper rotatable clamping jaw 26 is supplied with coolinr iuid through the pipe 33. n order that the upper rotatable clamping jaw 26 may be moved to and from the lower rotatable clamping jaw, so as to grip or release a blank or disk placed between the jaws, it is carried in a sliding journal bearing 32 mounted on the top frame 25. The longitudinal movement of the upper rotatable clamping .jaw 26 is accomplished by Huid-pressure in the cylinder 34 which is provi ed with a piston on the piston rod 35.

he piston rod 35 is secured to the crosshead 36 which is attached to the sliding journal bearing 32. Fluid under suitable pressure -is supplied to the cylinder 34 through'the pipe 37. It is therefore evident that a' blank or disk 40 centered on the pin 41 of the lower rotatable clampingjaw may be securely held or gripped by supplying fluid under suitable pressure to the cylinder 34 and simultaneously therewith the blank or disk may be rotated.

In order that the blank or disk may be moved to and from the rolls 3 and 4, a iuidpressure advancing and retracting means is provided. This comprises a cylinder 38 which is mounted on the overhanging portion 6 of the. guide-frame 5 and is supplied with fluid under suitable pressure through the pipes 39, thereby actuating a piston on the piston rod 15. The piston rod 15 of the cylinder 38 has a reduced end 17 which passes through the hole 16 in the carriage 7 and is secured thereto within the transverse inder 34.

tral hole, is placed opening 18 by the key 19. v

Y The o eration of my apparatus is as follows z-l luid under suitable pressure is admitted to the as toy retract sufiiciently'clear of the rolls to admit therequired blank between 'theclamping jaws, and the up r clamping aw is retracted b the upwar movement oy ythe piston in cy The blank which is preferably red or white hot and provided with a cenon'the lower clampingY jaw face-plate 29 with the central hole fit' front end of the cylinder 38 soA the disk holding mechanismv ting over the centering-pin 41. The piston of the fluid-pressure cylinder 34 isl thenforcibly advanced thereby causing the faceplates `27 and 29 of the clamping jaws'to firmly grip and hold the blank. .Fluid under pressure is now of cylinder 38 thereby advancing the. disk holding mechanism. In this way admitted to the rear end is presented to the bite of the rotating rolls 3 and 4, the advancement being so regulated as to gradually feed the blank into the rolls' and produce the form of disk illustrated 'or any other apparatus.

A reversal of these-operations will l.wi-th(- forms which may be made bythis` draw the disk in-its iinished vform and. prepare the apparatus for another blank where' upon the operation proceeds as before.

Although the blanks or rolled when the roll of rotation of the blank ,or disk, I prefer to arrange my apparatus so that the axesV of the rolls are slightly removed from the axis of rotation of the blank or disk as the rolling action will then tend to knead or pull the material toward the periphery of the blank or disk and further tend to increase itsdidisks may be axes intersect the axis,-

`ameter, as is necessary when it is being rolled f to tapered or reduced form. To this end the transverse movement of the adjustable frame 24 by the set screws 21 is provided.

AlthoughI have describedand illustrated I' my invention 1n considerable detail, I do not wish to be limited to the exact and specific details thereof as shown and described, but may use such modifications in, for, or equivalents thereof, as

pointed out in the claims.

Having thus described my invention, what I claim and desire to secure by'Letters Patent is 1. A disk rolling machine comprising av substitutions are embraced r` within the scope of my invention, vor as" uisa carriage slidably mounted upon said guide-frame, uid-pressure operated means adapted to reciprocate said carriage on said guide-frame, a superstructure mounted upon said carriage and adjustable transversely thereof, a pair of Huid cooled, rotatable clamping jaws mounted on said superstructure, and a Huid-pressure advancing, retracting and holding means for one of said clamping jaws.
