UNITED {STATES PATENT QFFIGE.
GEORGE B. PHILLIPS, OF CLEVELAND, OHIO, ASSIGNOR TO HIMSELF AND JOHN N. WILLARD, OF SAME PLACE.
IMPRCVEMENT IN MACHINES FOR DRILLING ROCK.
Specification forming part of Letters Patent No. 131,827, dated October 1, 1872.
To all whom it may concern:
Be it known that I, GEORGE B. PHILLIPS, of Cleveland, Ouyahoga county, in the State of Ohio, have invented certain new and useful Improvements in Ohain Drilling-Machines; and I hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawing forming part of this-specification.
The nature or essence of my invention conslsts 1n the particular construction, combination, and arrangement of devices forming the improvements described in the following specification, and represented in the accompanying drawing, in which- Figure 1 is the elevation of a drilling-machine with my improvements; Fig. 2 is a sectionon the line 2 z of Fig. 1 and Fig. 3 is a drill with a diamond or lozenge-shaped drilling-endfor enlarging round holes in two directions only.
In the drawing, AA are two parallel sills connected by the cross-sills B B to form the base of the machine: 0 G are two posts firmly fastened into the sills AA, and provided with two projecting pieces at their upper ends, to which the top bar 'D is fastened, which connects the upper ends of theposts, and is pro vided with a rotating collar or bushing, E, with a square hole through it for the drill-bar F totraverse in while the collar turns withthe drill-ban. The brackets G G are fastened to the posts 0 G to support the bar H, which is fastened to the brackets and perforated for the hub of the ratchet-wheel I, which turns in it as the wheel is rotated to turn the drill. To prevent the ratchet-wheel from being lifted by the drill a cap, J, is put over it and fastened to the barH. There are some brackets K K fastened to the rear side of the posts 0 O for the shafts L L to turn in, which brackets K are provided with friction-wheels M M, shown by dotted lines in Fig. 2. The sprocket or notchedwheels N N are fastened to the shafts L to carry the endless chain P which passes around both wheels, and the ends of the links are made like the joints of hinges or rule joints, which project on the inside and cannot slip on the wheels, as shown in Fig. 2,
where the flange of the upper wheel is broken away to show how the chain fits the wheel.
One or more of the links of the chain P is provided with a flange, Q, to catch under the arm R of the lifting-block S, to carry up the block and drill-bar F until the chain. begins to bend over the wheel N, so as to draw the flange Q out from under the arm R and let the drill and block down to make a stroke. The links of the chain P are made with square shoulders on the outside which butt together when the chain comes straight, and prevent it from bending in between the wheels so as to let the flange slip from under the arm R as it raises the drill. The lifting-block Sis made with a cavity in it for a small ratchet-block to turn in, which has a square hole in it in which the drill traverses, and there may be a pawl in the block to catch in the ratchet and prevent thedrill from turning back after it has been turned by the ratchet I. The cavity in the block S, and the ratchet in it, is covered by a plate fastened to the top of the block. When the flange on the chain catches the arm of the block and lifts it it tips the block so that it binds the drill and takes it up with it until the flange slips from under the arm and the drill drops and makes a stroke. By using a chain and my improvements the drill can be lifted to the height desired far more easily and with far less power than it can be done with a cam or wiper.
To turn the drill as it is raised I fasten the bar T to the post G and arrange the lever U to vibrate upon it, which lever has an inclined plane V fitted to its upper end so that it can be set higher or lower on the lever to turn the drill more or less, as desired. At the lower end of the lever the pawl W is fastened, and also the coiled spring X, which draws the pawl and lever back, after it has been vibrated by the arm R, to turn the ratchet-wheel I and drill F. To hold the arm R always in line of the lugs Q on the chain I fasten the rods (1 a to the bar D and cap J so that the arm will traverse freely between them. The drill, Fig.
Claim.
In combination with the lifting-chain P, provided with lifting lugs or flanges Q, I claim the lifting-block S, ratchet-wheel I, pawl W, lever U, and spring X, which turn the drill more or less, substantially as described.
In testimony whereof I have hereunto signed my name.
GEO. BAN GEHARTE PHILLIPS.
