MINING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,180, dated February 16, 1904.

Application filed Tune 20, 1903. Serial No. 162,441. (No model.)

To a/ZZ whom t mayconcern:

Be it known that I, EDWARD P. RAUscHEn,

l a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Mining-Machines; and I do hereby declare the following to be afull, 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.

This invention, relating to mining-machines of the pick type, has for its object to provide a cheap, simple, strong and effective construction which shall not be as liable to injury by' means for effecting the rotation of a reciprocable pick.

Other objects will appear from the following description.

The features of novelty are pointed out in the claims.

In the accompanying drawings, illustrating one embodiment only of the invention, Figure 1 is a top plan view, the cap for covering the driving-pinion and master-gear being removed. Fig. 2 is mainly a side elevation with parts in section. Fig. 3 is a detail of the pick, showing it coupled with the plunger of pick-stock. Fig. 4is a view of the operative end of the Vpick as seen from a plane at right angles to that used in Fig. 3. Fig. 5 is a horizontal sectional View of the rear bearing for the plunger. Fig. 6 is a rear elevation of the rear bearing. Fig. 7 and Fig. 8 are rear and side elevations, respectively, of the forward bearing for the plunger. Figs. 9 and 10 are rear and side views, respectively, of the trunnions upon which the wheels to support the machine are journaled. Fig. 11 shows the swivel connection between the rear end of the plunger or pick-stock and pitman.

1 and 1DL are upper and lower frame bars orI beams, respectively, extending longitudinallyT of the machine.

2 is the casing for containing the motor or driving apparatus. This is indicated to be an electric motor; but other kinds of apparatus can be employed. The frame bars or beams 1 and lL are secured at their rear ends in lugs 'will not be disturbed.

'length and to converge toward each other in their forward portions, the forward extremities being focused in the piece 3, containing the forward bearing.

4 designates the bracket or piece containing the rear bearing for the plunger. This is held between the four frame-bars 1 1 and 1 and 1f* by means of clamps 4, embracing the bars and clamped to the bracket 4 by bolts. bracket 4 and the clamps 4 serve also to brace and retain the frame-bars l and 18L in stable position near their middles.

5 designates the tool-stock or plunger. This has a sliding fit in a collar-bearing 6, secured in the bracket 4. The collar-bearing has on its outer side a spherical or ball contour fitting .in a socket corresponding in contour on the toothed gear 6a. This collar-bearing also has a key or spline 6b to engage a longitudinal keyway or groove 5a in the plunger or pick-stock, so that kthe latter can be rotated axially while reciprocating longitudinally. Room will be left in the bracket4 at each side of the collarbearing t0 permit the bracket to rock universally on the collarbearing. In other words, should the frame be distorted by falling coal or rock the alinement of the collar-bearing The bearing for the forward end of the pick-stock can be in all respects like that just described in connection with the bracket 4, except, of course, that the toothed gear 6*l need not be duplicated there. The bearing of the pick-stock in the bracket 4, as well as that in the part 3, might appropriately be termed a universal or Lballand-socket bearing.

7 designates the master driving-gear. This is supported on a web or shelf projecting for- 'ward from the casing 2. The lower end of the shaft 7 a of the master-gear is furnished with a crank 7b. The master-gear is driven The The collarbearing 6 has secured to or cast with it a` roo v l the spring or crank-rod.

by pinion 8 on the power-shaft 8a. Connected with the crank 7 b is a pitman 7 c, and interposed between the pitman 7C and the rear end of the pick-stock 5 is a spring 9, the ends of which are hooked in links 10, said links being caught under hooks 1l on a collar 11, swiveled on the rear end of the pick-stock 5. The swiveled connection between the spring and the plunger is illustrated in detail in Fig. 11. This connection is made swiveled, so that the pick stock in the particular construction shown can be axially rotated without rotating shown to be held on the pick-stock by means of a nut 5b, wliichcan be suitably locked to prevent it from turning off.

'The swivel connection just described can be located between the spring 9 and the pitman 7c instead of between the spring and pick-stock.

Handles 12 on the casing 2 for convenience in moving, holding, and directing the machine in operation are shown to be provided.

The toothed gear 6 is shown to be engaged by a pinion 13 on a shaft 13, reachingA rearward to the rear of the Amachine within convenient distance of the operator, a hand-wheel 13b being provided for turning the shaft, so that the position of the cutting end of the pick can be varied. 14 designates-the pick. This preferably is removably coupled by a coupling 14"L to the pick-stock 5. The coupling 14 is made with a transverse hole 14D, into which a drift' may be driven to loosen the pick when it is desired to remove it.

15 designates a trunnion for one of the carrying-wheels 16. The trunnion projects laterally from a base 15, and the latter has perforated ears 151 to permit the base to be slipped on and secured to the frame-bars 1 and l, l

The master-gear 7 and pinion 8 can be protected fromfalling things by an appropriate hood 2d, removably attached to the casing 2. The operation, which can be readilyunderstood from the Jforegoing description and the accompanying drawings, is very simple. The machine is moved up to a wall of coal and the pick directed toward the place in the wall to be cut. The rotation of the master-wheel effects, through the crank of its shaft and the pitman, a rectilinear reciprocation of the toolstock and pick. The impact of the pick breaks up'the coal, themachine being moved on its wheels to -make the cut as desired.' I/Vhile thepick is reciprocating the cutting end thereof can be varied in its position, as before stated. It will be observed by those skilled in ma.-

i chinery that the frame-bars 1 and 18L can be machine.

considerably bent or distorted without materially interfering with the operation of the This is because the universal bearings in the bracket 4 and part 3 are maintained in their horizontal or normal position, even though the surrounding frame be moved to some extent out of its primary position.

The collar 11 is What I claim, and desire to secure by Letters Patent, is-

1. In a mining-machine of the pick type, the combination of a frame, a socket-bearing supported in the frame, a ball universally movable in the socket-bearing, a pick-stock passing through and reciprocable in said ball,

and means for mechanically rotating the pickstock. 2. In a mining-machine of the pick type, the combination of a frame, a reciprocating pick-stock supported therein, and universal bearings in the frame for the rear and forward portions of the pick-stock.

3. In a mining-machine of the pick type,

the combination of a frame, a reciprocatingV and rotatable pick-stock, a universal bearing in the frame supporting said pick-stock, said bearing connected with said pick-stock to `rotate therewith and having a gear thereon, a rearwardly-extending shaft supported in the frame having thereon a pinion to engage the aforesaid gear.

4. Ina mining-machine of the pick type, the combination of a frame, a reciprocating and rotatable pick-stock, a universal bearing in the frame supporting said pick-stock, a

gear connected with said pick-stock, a rearwardly extending shaft vsupported in the frame having' a pinion thereon to engage the aforesaid gear.

5. In a mining-machine of the pick type, tledcombination of a motor-casingl 2, a bearing-piece for the pick-stock, a ball supported in said bearing-piece and universally movable therein, frame-bars 1 and 1f* connecting said motor-casing and bearing-piece, a pick-stock supported in the ball and reciprocable therein and means for reciprocating the pick-stock.

6. In a mining-machine of the pick type, the combination of a motor-casing 2, a bearing-piece 3, frame-bars 1 and l, connecting said motor-casingand bearing-piece, a bearing-bracket 4, and a reciprocable pick-stock supported in the bracket 4 and bearing-piece 3, and means for reciprocating the pick-stock.

7. In a mining-machine, the combination of frame-bars 1 and 1, a trunnion for a carryingwheel thereof comprising a base portion adapted to engage said bars l and l, and a spindle projecting from said base to receive the wheel.
