EDWIN E. SLICK, OF PITTSBURG, PENNSYLVANIA.

- EUTARY sHEARs.

To all 'whom it 'may concern:

Be it known that I, EDWIN E. Suck, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Rotary Shears, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of 'this specification, in whichi Figure 1 is a plan view of rotary shears apparatus constructed in accordance with my invention; Fig. 2 is a front elevation of the same partly in section; and Fig. 3 is a side elevation, partly in sect-ion. l

My invention rela'tes to rotary shears, and particularly to the shearing of hot ingots or blooms of substantially cylindrical form.

The invention relates particularly to the forming of steel wheel blanks from a cast steel`ingo't, though it'may be employed for cutting off tire blanks or other blanks from a long cylindrical blank or section.

The object of the invention is to provide a simple, cheap and rapidly-operating device by which the blanks may be sheared from the ingot, and if desired, partially shaped during the shearing action.

In the drawings, 2, 2 represent the rotary shear blades whiclrare mounted on shafts 3, 3, the blades either being rotatably mounted on the shafts or being secured to the shafts which turn in suitable bearings. In either case, the rotary shear blades are positively rotated, this being done in the form shown by wabblner connections e to pinions 5 and (i. driven from the intermediate pinion 7. The bearings for the rotary shears are carried on 'SlidingcrOss-heads 8 moving on guides 9. The cross-heads are moved toward or from each o'ther by hydraulic or other fluid pressure cylinders 10, and kare drawn back by the .pull-back cylinders 11. In order to cause uniform travel of thetwo shear blades, I preferably connect the crossheads by

links

12 and 13 with the oppositely projecting equalizing levers 14a and 14b sel cured on the pivot shaft. 14. Other means,

however, may be employed for making 'the travel of the two shear blades uniform, or such device may be done awayfwith entirely. l t

The ingot to be sheared is carried upon a suitable support which I have shown as consist-ing of two rows of antifriction rollers 15, and an antifriction roller 16 between and below 'the two shear blades. 'The ingot lies upon these sets of rollers, and may be ad- Speceaton of Letters Patent. Patented July 19, 1910.

justed forwardly by the pointed end 17 of a plunger 18 in the cylinder 19 in line with the roller 16. j I

In the operation of the apparatus, the cylindrical ingot is Alaid on the antifric'tion rollers in substantially the -position shown inv dotted lines in I1`igs.-1 and 2. It is then shoved forward by the pointed end of the plunger 1S, so that i'ts front end projects upon the shears the desired distance. The shears are then positively rotated, and .at the same time simultaneously moved toward each other. They gradually enter 'the sides of the ingotand cut a deepening annular groove therein, the fluid pressure cylinders 1() finally bringing the two shear blades togethe'r, if this is desired. The operation may also be carried out without completely severing the blank, as the remaining neck or stem portion may afterward be cut away or ren'ioved, either by punching a central hole inv the blank, or in any other desired way. After the blank is thus severed, 'the cutting disks are retracted, the ingot is adjusted forwardly to the proper distance, and the 0pof cutting off one blank, the'circular hub portion 2O of the shears acts upon the next blank to size it before it is cut off, thus in the form shown, there is a sizing action on one blank simultaneously with the cutting off of the other blank ahead of it.

rThe ingot may be supported upon centers projecting into centering holes in its opposite ends. The shape of the shear blades may be varied so as to simply cut the blank, or to partially shape the blank being cut, or the next blank being cutoff or both; and many other changes maybe made without departing from my invention.
