IMPROVED DRILLING AND PUMPING APPARATUS.

TO ALL WHOMIT MAY'CONCERN:

Beit known that I, MARK T. McCoRMICK, of the c ity of Meadville, in the county of Crawford, and State of Pennsylvania, have invented a new and improved Machine for Sinking Artesian Wells; and I do hereby declare that the following is a.. full and exact description of the same, reference being had to drawings and the letters of reference marked thereon. l 4

The object of my invention is to drive iron pipe to the depth required to find water, and in doing this the pipe will frequently strike hard-pan or rock, which would prevent. its being farther driven unless a hole could be drilled through the'rock or hard-pan. My machine is a combined drill and ram to' drive the pipe after the drill, and at the same time, whenever it is desired, a pump can be attached to test the well.

Figure 1 is a front elevation of xny machine.

A are the sills of th'e frame, on whieh'the upright posts B C .C are erected.

H -is'a eoggeddriving-wheel.

Y is n smaller cogged wheel gearing into H, and may be thrown in and out of gear by any suitable device.

W W is the drill-stem with a pin at the accompanying D is a lever, which, on.the removal Aof a pin, 8, and the pin x, falls down in the position shown in Figure 8. t

The lever D is operated by the pin 5 in the smalLcogged wheelY, This moves the drill-stem w zu up and down, thereby giving a blow to the drill which is necessary in going through rock. l

The drill-stem 'w w is square, and passes through the small bevel-gear wheel G, which gears into the driving-wheel H. The drill-stem is constructed so as to move freely up and down through the wheel G, and by this construction the wheel G gives the drill-stem a rotary motion, while the lever D gives it an up and down motion or a blow."

M is a segment of cogs from 6 to 7, attached to the face of the wheel H.

O is the driving-ram. P and P. are two guidesrods; the one, P', having a'cogged rack, N, :at its upper end. This rack gears into the segment M as the wheel H revolves, thereby lifting the ram O the length of the rack N onceat every revolution of the wheel H, and when the segment M has passed letting the ram droponthe head of the pipe Z Z.

1 shows the ram up, and Fig. 8 the ram down on the head of the pipe Z Z.

l Z Zis the wellftube,` which is constructed in sections, and screws together in the couplings a a.

The lower end of the drill-stem w w screws into a short pieeevof tube of the size of the inside of the welltube Z Z. This short piece of tube is perforated with holes, as shown at Sfand4 the drill-head R-is screwed on the lower end of the same, and when the well is sunk to the desired depth, the well-tube Z Z is drawn up, or the holev is drilled down a few inches lower than the tube Z Z, and the water enters through the holes in S into the well-tube; S acting as a strainer to prevent the entrance of gravel. In sinking` a well through soil, if there is no rock in the way, it is` not necessary-that the drill should have a blow or an up and down motion, but only a. rotary motion, and for this purpose the lever D is detached by the removal of the pin x, and then lifting the lever D in the position shown in iig. 1, and inserting the pin 8,. l The drill will now have a rotary motion only, and at every revolution of the wheel H the ram will make one blow on the tube Z Z` thus drivin(1r the tube down after the Vdrill R; Now when the drill R strikes a. rock so hard that the drill cannot cut through it, and it is found necessary toA use another drill, like m, Figure 4, the tube Z Z must be drawn and the drill R removed,

arid a drill, m, g. 4, put in its place. This drill is constructed as follows, to wit: 3 is a steel point, with n' chisel-shaped cutting face at 3; 1 and 2 are wings of steel, welded on the point at 4, with cutting edges at 1, 2. The tube Z Z, and drill-stem, with drill m., fig. 4, are now inserted in the well-hole, the lever D lowered on and attached to the drill-stem ww; the wheel Y thrown in gear, and

This position lifts th'e cogged rack N above the reach of the segment M. Thus the ram` remains stationary while the drill has the two motions before described, 2'. e., up and down, and rotary. v
