WILLIAM A. SWEET, OF SYRACUSE, NEW YORK.
ROLL FOR ROLLING STEEL BARS FOR MINING-DRILLS.
SPECIFICATION forming part of Letters Patent No. 228,486, dated June 8, 1880.
Application filed January 14, 1880.
To all whom it may concern:
Be it known that I, WILLIAM A. SWEET, of the city of Syracuse, Onondaga county, State of New York, have invented certain new and useful Improvements in Rolls for Rolling Steel Bars for Drills for Mining and other Purposes, of which the following is a specification.
Heretofore drills for mining, quarrying, and the like have been made by forging, and were very imperfect in their construction, involving much expenditure of time and labor, and re quirin g constant repairs.
I have devised a pair of grooved rollers by which I am enabled to roll steel bars readily into shape of proper form throughout their entire length, for the purposes of a drill for mining or quarrying, of equal and correct configuration, as seen in Figure 2 in the drawings, in their cross-section.
My device for forming said bars consists of a pair of rollers, seen at Fig. l of the drawings, which is a front elevation thereof. In these rollers three (more or less) grooves are made, of rectangular form, or nearly so, as seen in Fig. 1, if the bar is to be rolled into the form shown at Fig. 2. The form can, of course, be modified iorother cross-sections if desired. The rollers are chamfered off at the edges of the grooves, as shown at c a a, Fig. 1, the grooves gradually diminishing in size from 1 to 3. The top roller can be set down in the usual way for the horizontal fins on the bar.
To reduce the bars to drill-steel by my process, of proper form for drills without forging, they are heated and run through the grooves No. l a sufficient number of times, setting the top roller down each time until the horizontal web of the bar is thin enough to pass into the vertical grooves or pass No. 2. The bar is then turned a quarter round and run through this groove. The horizontal Web is rolled thin enough to enter the next smaller grooves, No. 3, when it is again turned a quarter-turn and passed through the finishing pass, No. 3, through which it is passed a number of times to condense and finish the steel bar and bring itto the exact size wanted, giving the bar a quarter-turn each time, after which the finished bar is cut into proper lengths for drills.
Having thus fully described my method of forming drill-steel for mining, 850., I claim The rollers herein described, grooved, beveled, and operated as above specified, for forming drill-steel, substantially in the manner and for the purposes herein set forth.
W. A. SWEET.
