Specification of Letters Patent.
Patented Mans, 1922.
Application filed February 4, 1921. Serial No. 442,512.
To all whom it may concern:
Be it known that I, AARON ITEISLER, a citizen of the United States, residing at Pittsbur h, in the county of Allegheny and State of ennsylvania, have invented certain new and useful Improvements in Chipping Machines, of which the following is a specification.
This invention relates to machines for cutting grooves in metal billets; and it consists in the novel construction and combina tion of the parts hereinafter fully described 1 port for the and claimed whereby the billet of metal to be grooved is supported and moved longitudinally under the cutting or chipping tool, and whereby the said tool is adjusted and operated.
Ill-the manufacture of high grade tool steel, the steel is cast into ingots which are rolled out into billets. These billets are usually square in cross-section, and they frequently have longitudinal fissures or hair cracks intheir surfaces. These cracks are nearly always parallel to the sides of the billet, and it is necessary to cut longitudinal grooves where they occur, as subsequent rolling does noteliminate these hair cracks from the billets, and it is not desirable that they should show in the finished product. When the hair cracks are cut out by forming grooves in the billet, the grooves so formed roll out with the metal, so that the surface of the finished product is free from cracks and imperfections.
In the drawings, Figure 1 is a side view of a chippingmachine constructed according to this invention. Fig. 2 is a plan view of the machine. Fig. 3 is a cross-section through the guide, taken on the line 3-3 in Figure 1, and showing some adjacent parts. Fig. l is an end view of the supfront end of the cutting tool. Fig. 5 is an end view of the machine. Fig. 6 is a cross-section through the guides of the saddle which supports thev chipping tool, taken on the line 6-6 in Fig. 5.
The machine is provided with a supporting frame 7, and 8 are rollers arranged parallel to each other at suitable distances apart in a horizontal plane, and journaled in bearings 9 on the frame. Sprocket wheels 10 are secured to the roller shafts, and 12 is a drive chain which passes over all the sprocket wheels and drives all the rollers in f the same direction. Thechain is operated first monedirection, and then'in the reverse direction by any approved motor or driving mechanism. The steel billet 14 is placed on the rollers, and s supported by them in a horizontal position, and is moved back and forth'longitudinally. A longitudinal guide 15-is secured to the front partof the frame at one side of the machine, between the ends of the rollers and the sprocket wheels. A book shaped or channel-shaped slide 16 is mounted on the guide 15, and is provided with a lug 17 which is bolted to the drive chain. One end portion of this slide engages positively with one end of the billet, so that it forms an abutment which prevents the billet from sliding rearwardly while being cut. Plates 18 are secured to the frame, and are arranged horizontally in the spaces between the rollers, to catch the chips which are cut off the billet.
A percussion tool 20 is preferably used for cutting the grooves, and it has a diamond-point. cutting tool or chisel 21. The tool 20 is preferably a pneumatic tool similar to a rock drill or a riveting machine of approved construction.
The chisel 21 is reciprocated longitudinally, and is arranged at anangle of about 45 with the horizontal. In carryin out this invention other tools may be use. for forming the grooves in the billet, such tools being of approved construction.
A bracket 84 is also secured to the frame, and projects over the front end portion ofthe "000120. A screw 35 has a yoke 36 at its lower end which is pivoted to the front 'end portion of the tool by pins 37. The
screw. 35projects vertically through a slot in :the bracket 34:, and is provided with a hand-wheel 39 which is screwed on it.
The 'angle of the cutting tool or chisel is adjustedby means of this hand wheel and screw. The cutting tool or chisel 21 is reciprocated by power, and is adapted to strike much harder blows, and more rapid blows, than can be accomplished by hand, and it cuts \hshaped grooves in the billet, and therebyeliminates the hair cracks. The uprights 25 are preferably slid vertically by means of a driving shaft -10. Bevel wheels 4,1 are securedonthis shaft, andon the lower end portions of screws 4-2 w-hich work in nuts 43 secured to the uprights,- so that the two uprights are slid up and down simultaneousl The shaft 40 is .driven by any approved means, and is revolved first in one direction and then inthe reverse direction.
The rollers carry the billet back after each groove is cut or chipped in it, and the billet can be turned over so thateach' side of itrcanbe operated on if necessary.
Machines constructed according to this invention canhave their cutting tools operatedby other approved means,as well as by compressed air or other fluid. They can also be used to operate on allkinds of metal which comes in billets or blooms, and they can he used to-remove ridges or fins from the sides ofthe billetsor blooms as well as for cutting grooves inthem.

A support for the work, a percussive power driven tool for cutting the work, uprights for supporting the said tool, a crosshead secured to the rear tool and pivoted in the said uprights, asta-' tionary bracket, and adjustable means for supporting the front end portion of the tool end portion of the from the said bracket and adjusting the tool pivotally to vary its angle With the work support.
12. A support for the Work, a percussive power driven tool for cutting the Work, uprights for supporting the said tool, a crosshead secured to the rear end portion of the tool and pivoted inthe said upright, a stationary bracket, a screw pivoted to the front end portion of the said tool, and a hand 10 Wheel engaging with the said serew and supported by the said bracket.
