UNITED STATES- PATENT OFFIC GEORGE L. WELLER, OF ELYRIA, OHIO, ASSIGNOR TO PARKS FOSTER AND EUGENE K. MUSSEY, OF SAME PLACE,
ROCK-DRILLING TOOL.
S-PECIFICATION forming part of Letters Patent No. 479,041, dated July 19, 1892. Application filed November 23,1891. Serial No. 412,849. (No model.)
To aZZ whom it may concern.
Be it known that I, GEORGE L. WELLER, a citizen of the'United States, residing at Elyria, in the countyof Lorain and State of Ohio,
have invented certain new and useful Improvement-s in Rock-Drilling Tools, of which the following is a specification.
My present invention relates to a drill adapted to drill in stone a hole having V- shaped or angular ends, and more particularly a hole having V-shaped ends and sides which are parallel to each other and to a plane passing through the points of said ends,'as described in my application, Serial No. 412,8i8,
filed concurrently with this specification.
In the drawings, Figure 1 is a side eleva tlon of the drill and aseotional elevation of.
the rock in which the drill is making the hole. Fig. 2 is an edge view of said drill,
Fig. 3, a top sectional view on line 3 3 of Fig. 1; and Fig. 4: is an end view or view of the operating-face of the drill.
The drill may be operated by hand or by any suitable rock-drilling machine; but the drill is not to be rotated, but is to be reciprocated in the same straight lines when used in drilling the holes.
Referring to the parts by letters, A represents the head of the drill, which is larger in 0 every cross direction than the shank B, on which it is formed. The face of the drill is slightly convex, as shown in the drawings, although I do not regard a drill otherwise constructed than as shown and claimed, which 5 has a straight face, as indicated by the dotted line 1 in Fig. 1, as a departure from the invention. The face of the drill has two parallel sides a a and V-shaped or angular ends a a, and the sides of the drill, as shown, are equidistant from a line extending between the points of said ends. herefore it follows that if the drill be not revolved, but be caused to move in the same straight lines at all times, the hole drilled thereby will be a hole having angular ends and sides which are 5 parallel to and equidistant from a plane passing through the points of said ends.
In using this drill the hole is kept supplied with water, and in order to permit the water to pass into the hole below the drill-head when the drill is raised said head is provided with the channels a (F. The action of the drill as it descends is to pulverize the rock beneath its face. As the drill is raised the Water rushes down through the channels a a and causes the pulverized rock to mix with it. As the drill again descends the water holding the pulverized rock in suspension rushes through the channels (t a to a point above the head. The head of the drill acts, as it continues to reciprocate, as a pump-piston lifting out of the hole some of the water and pulverized rock which it holds in suspension, and fresh water is constantly supplied from a nozzleO or its equivalent. It is therefore unnecessary to stop the action of the drill in order to remove the accumulating debris with a sand-pump, as is customary with the forms of drills ordinarily used.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1. A rook-drill having a shank l3 and an enlarged head provided with the channels a a the operating-face of said head having V-shaped ends, substantially as set forth.
2. A rock-drlll having a shank B and an enlarged head provided with the channels a a the operating-face of said drill having V-shaped ends and straight sides, which are parallel to and equidistant from a straight line extending between the points of said V- shaped ends, substantially as set forth.
