COAL-MINING MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,284, dated December 28, 1886.

Application filed March 20, 1886.

To all whom it may concern.-

Be it known'that I, JOHN WALTON, acitizen of the United States, residing at Philipsburg, in the county of Centre and State of Pennsylvania, have invented certain new and useful Improvements in Coal-Mining Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will .enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has for its object to provide an improved and novel construction of coal-mining machines, which combines in its construction and operation a high degree of efficiency, utility, and ease of adjustment with a ready adaptation to the purpose contemplated; and my improvements consist, essentially, of the details of construction and general arrangement of parts, all as will be hereinafter fully described, and specifically designated in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of my improved apparatus; Fig. 2, a vertical transverse section taken 011 the line a roof Fig. 1, and Fig. 3 an end elevation.

Similar letters of reference occurring on the several figures indicate like parts.

The frame of my improved machine is preferably rectangular in shape, being composed of the end uprights, A A, united together by the cross-beams B B and-side rails, O 0, each of the parts being detachably secured together by means of suitable connecting bolts or screws to permit of thesanie being taken readily apart for transportation from one place to another, or as easily placed together to form the frame or standard upon which the operative mechanism is supported, said frame or standard being secured in the desired position by means of the spurs or points a upon the lower corners of each of the end uprights, A A, and by the chisel-pointed ends of the screw-threaded rods 1) upon the upper part of the said end uprights, the lower points or spurs, a, projecting into the floor of the coal-passage, and the points of the screw-threaded rods 1) projecting into the'roof Serial No. 195,985. (No model.)

of the same. The screw-threaded rods b fit into correspondingly-threaded openings in the cross-beams B B of the end uprights, A A, and, being provided at their lower ends with a hand-wh eel, b, are capable of being adj usted up or down, according to the height of the roof. By turning the hand-wheels b the rods bare moved vertically in their threaded journals, to project into the same to hold the frame or standard in arigid position during theoperation of the machine.

The lower side rails, 0, one on each side of the frame, are each provided upon their upper surfaces with a V-shaped or other suitablyshaped flange, 0, extending the entire length of the rail, while the upper side rails, O,'have an arched groove, 0, upon their lower sur aces for the reception between the said upper and lower rails of the carriage D, the lower and upper ends of which conform in shape to the said flange c and groove 0 to permit of the said carriage D being held between said side bars, 0 G, in position to be readily moved forward or back within the limits of said frame or standard.

Near the lower end of the carriage D, and rigidly secured thereto, are provided plates (1, one on eachside, having central openings for the passage of a screw-th readed rod, E, the ends of which are secured between the end uprights, A A, by means of headed bolts e, passing through the same and fastened in place by suitable nuts, as fully shown in Fig. 3.

At each end of the screw-threaded rod E, and adapted to move upon thesame, are provided hand-wheels F, having corresponding screw-threaded central openings for the reception of the rod E, for propelling the carriage in either direction within the limits of the frame or standard.

Suitably journaled in the upper part of the carriage D is provided the driving-wheel G, which maybe operated by hand or other suitable motive power, and the cogs or teeth of which mesh into the cogs or teeth of thesmall pinion G, which is also suitably j ournaled in the sides of the carriage D, beneath the driving-wheel G. The axis of the said pinion G'is, hollow from end to end for the reception therein of the outer end or shank of the coal cutter or drill H, which may be held at the desired position in the axle of said pinion by means of the set-screws g, as fully shown in Fig. 2.

In the operation of my improved apparatus the cutting-tool first drills or bores a hole about three feet deep into the coal. Then the same tool changes its course from right to left, or vice versa, and cuts across the face of thecoal as the carriage is propelled along the screwthreaded rod E, the depth of the cut for the entire length of the frame remaining three feet deep where steam-power is used; but where hand-power is employed such out can be only eighteen inches deep,11ecessitatin g the carriage being run back to make another cut of like depth, which makes three feet deep, or equal to one cut by steam-power.

Having thus described my invention, I claim as new and useful 1. A' coal-mining machine consisting of a frame having standards with top and base horizontal side rails secured thereto, rigid base projecting points, adjustable screw-threaded and pointed vertical rods journaled to the face of said standards and provided withend ad- 2 justing-wheels, in combination with a carriageframe having gear-wheels journaled within, as described, and provided with end flanges and grooves adapted to loosely fit and move horizontally on said rails, substantially as shown and specified.

2. In a coal-n1ining machine, avertical carriage-frame provided with a gear drivewheel, and a pinion with hollow axle, as a drill-chuck, and in which the drill is secured, in combination with a carriageframe having top and base horizontal beveled bearings adapted to receive and loosely hold by end bearing said carriage frame, substantially as shown and specified.

In testimony whereofI affix my signature in presence of two witnesses.

JOHN \VALION.
