ROTARY SHEARS.

Specification of Letters Patent.

Patented; July 19, 1910.

Application filed June 14, 1909. SerialNo. 502,017.

To all whom it may concern:

Be it known that I, EDWIN Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Rotary Shears, of which the following is a full, clear, and e:;act description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial plan viewof my im-- proved apparatus; Fig. 2 is a continuation of Fig. 1; Figs. 3 and 4 are views siinilar'to Figs. 1 and 2, showing a sectional side elevation of the apparatus; Fig. 5 is a front elevation of the shear mechanism; Fig. 6

is a sectional end elevation of the supporting mechanism-in front of the shears with the metal in place; Fig. 7 is an enlarged eleva-' tion of the cutters; Fig. 8" isa similar view showing a modified form; Fig. 9 is an edge View of the cutter or knife of Fig. '8; Fig. 10 is a diagrammatic end view showing the manner of cutting through the ingot.

ldy invention relates to the shearing of i te and is designed to provide an improved apparatus therefor. In the drawings, in which I show a'preferred form of my invention, the ingot shown at 2- is arranged to be carried on a longitudinal positively driven roller 3, which, in turn, is carried at one end. on two idle rollers 4, and on the opposite end by the bearing 5. The roller 3 is shown as extending the entire length of the ingot and in turn is supported on the pair of rollers 4 and the cap bearing 5. The roller 3 is arranged to be adjusted so as to support ingots of varying diameters in proper position relative to the shear knives. As shown in the drawings, this roller support 3 is raised and lowered vertically by inserting or removing the liners 4 from between the roller supports 4 of the base plate 4.

Along the sides of and above thesupports ing roller 3 are

side guides

6 and 7, which are designed to engage with the sides of the ingot and hold it against sidewise movement while being moved endwise in feeding the ingot forwardly and during the cutting operation. The ingot may be fed into position between these guides over the skids 8. The roller 3 1s positively drlven by a bevel gear connection shown at-S), with a shaft E. SLICK, of;

10, having slow motion gearing 11, which is actuated by an electric motor 12. The metal.

is pushed endwise or longitudinally of the roller 3 and between the

guides

6 and 7 by means of a rotary pusher head 13, which is fastened to the front end of an arm or bar l4, so as to rotate on the bar with the ingot when-in engagement with the end of the ingot. The arm 14 is engaged by azfriction roller 15, driven through slow

motion gearing connections

16 and 17, by an electric motor 18. The idle supporting rollers 4'may be either continuous rollers supported at each end in hearings, or may be in the form, shown, namely, shafts having over hanging disks 4, mounted thereon.

The apparatus above described sits in front of and in line with the shearing mechanism. proper, the lines X-X, i -Y of Figs. 1 and 3 coinciding with the lines XX and YY of Figs. 2 and 4, to show the relative positions of the apparatus.-

This shearing mechanism consists of two eccentric

knives'or shear blades

19 and 20.

In the form shown, these eccentric knives are formed as disks with eccentric edge portions clamped between collars-21, which secure them on the shafts 22. The collars 21 are adjustably held in their spaced apart position and serve to support and prevent sidewiseinovement of the ingot during the cutting operations. The shafts 22 with the knives l9 and and the collars 21 are adjustable toward and away from each other, and are held in their adjusted position by the adjusting screws 23 and lock nuts 23*; and where changes in the size of the ingot are very great, collars of greater or lesser diameter are substituted. tend within the bearings 23, in the housings 23, and are connected by spindle and coupling connect-ions 24, with a stand of driving pinions 25, which receive motion from a driying shaft 26.

Beyond the eccentric shear blades and between thcni is located a rotary cup-shaped holder 27, arranged to engage with and hold the end of the ingot durmgthe cutting operation and to hold the cut off portion. Thisholder is mounted on a tubular stem 28, which slides over a stationary rod 29,-

secured to the housing '23 at its rear end. The tubular support 28 is rotatably mounted The shafts 22 errin bearings 30, which are carried on a slidmg frame 31, connected to the intermediate portion of a double plunger 32, moving within single acting hydraulic cylinders 33. Durmg the cutting operation, the holder 27 rotates with the ingot and after the cutting operation, it is retracted to allow the cut off section to drop. If the section sticks in the holder, the rod 29 acts to push it out as the holder is retracted. The out OK section drops down, preferably into a car 3st, movable on a. track extending below the shears.

In Figs. and 9, I show a. modified form of shear knives, in which the portions 35 of the eccentric shear blades are removable,

- so that when theygare worn, they may be re placed. I have shown these detachable sec tions as attached by countersunk bolts 36, to the cutter disk, which disk is then secured to the shaft in the same manner as before;

In the operation of the device, an ingot which is preferably cylindrical in form is rolled over the skids on top of the roller 3 and between the guides G and 7. The roller 3 is then positively rota-ted and the cutting knives are rotated in a vcounter-clockwise direction, looking at Fig. 5. As the knife shafts rotate, the eccentric knives will gradually sever the ingot from diametrically opposite sides by a succession of cuts, the cutting action being illustrated in Fig. 10. During this time, the ingot is being rotated both by the frictional action of the eccentric knives and also by the frictional driving action of its supporting roller, which is positively driven. The driving of the rotary supports for the ingot is of importance, especially toward the end of the operation, since the friction on the knives at such time is hardly sufiicient to turn the piece being cut. During this operation, the holder keeps the end of the piece in proper position and holds it after it is severed from the main body. The collars 21 stiffen the

shear knives

19 and 20, and also serve to maintain the body portion of the ingot in position and prevent its sidewise movement on the support 3 during the cutting operations. The holder is then retracted andthe severeddisk or cheese-like section drops 1nto the car. The pusher 13 is then actuated to move the ingot forwardly a proper distance for the next severing operation. During this interval, the ingot slides between the disks carrying the eccentric knives, which knives are then in the position shown in Fig. This pushing is'continued until the end of the ingot is again received ip the holder, which, in the, meantime, ha been moved forward into the desired position. The holder, therefore, also acts as a gage.

In order to cut different sized ingots,

shear knives of different sizes may be substituted, and if desired, the degree of cocentricity of the knives may be varied.

The advantages of my invention result from the simplicity of the apparatus and the rapidity of operation. The blank is sheared 01f flat on'one face and slightly conical on the opposite face, with very little upsetting action at its edges.

Changes may be made in the form and operation of apparatus without departing from my invention.
