carried by a shaft 12. The shaft 12 carries spaced collars 13 engaging opposite ends of a bearing 14 mounted on a carriage made up of side members 15 and cross members 16, the side members being provided at their lower edges, with grooved foot members 17, adapted to engage inclined tracks S, so that the carriage may slide along the tracks.

Mounted between bearing blocks v2O on the carriage 151G is a worm 21 carried by the shaft 12, but secured to said shaft for rotation only, the shaft 12 being slidable through the worm 21, the latter being held against sliding movement by the blocks which also form bearings .for the shaft 12. Beyond this worm 21, the shaft 12 carries a pinion 2;., engaged by a worm 23 on the armature shaft of an electric motor 24, the pinion 22 being elongated, so that the shaft 12 may have longitudinal movement, while the motor 24 is imparting rotary movement to theshatt 12. The worm 21 engages a pinion 25 on a shat't 26 supported tor rotation in the side members 16 of the carriage, the sha tt 2G being extended into the hollow side member 1 as shown in Fig. 1. In the inside plate 4, there is a slot 27 in which the of the machine. shat't 12 moves, this slot 27 being parallel to The drawings4 show typical embodiments the track S. The slot 27 permits the carriage merely, and it is to be understood that to be advanced and retracted in, the comchanges, properly falling within the scope partment A. The shaft 2G carries an ecot what is claimed, may be made without centric 2S to which is applied an eccentric strap 29 having an arm 3() the free end of which is pivoted to a pin 31 carried by a member 32 secured to the bearing 14. Thus, as the shaft 26 is rota-ted, the bearing 14, and consequently the shaft 12 and the cutter 10 will be reciprocated, at the same time that the cutter 10 is rotated by the motor 24 Disposed in the side member 1, is a rack trame 35, havingstuds 36 at its ends, adapt.- ed to register in inclined slots 37 in the plates` 3 and 4. Mounted upon the shaft 2G is a pinion 44, located within the rack trame 35. The rack frame may be slid longitudinally by any desired means. `When the rack frame is thus slid in one direction, the studs SG will traverse the slots 37, elevating the rack frame 35, and causing the pinion 44. to mesh with the teeth in the lower part' ot' the rack frame. When the rack frame 35 is slid in an opposite direct-ion, the rack traine will be depressed, causing the pinion 44 to mesh in the teeth in the upper part ot the racli frame 35. By thus manipulating To all w? n it may concern:

Be it known that I, Loris F. Hess, a l citizen. of the United States, 'residing at. Hawks Nest, in the county ot Fayette and State of lVest Virginia, have invented a new and useful Attachmentfor Mining-)fiachines, of which the following is a specitil cation. v l The device forming the subject matter ot this application is a mechanism for operating .a conveyor, adapted to be employed upon mining machines, of the type shown I and described in my co-pending application, Serial No. 554,781.

It is the object of this invention to pro' vide mechanism for actuating a conveyor, adapted to constitute a part of a machine of the sort above mentioned, the conveyei operating to remove the dust and detritus accumulating at the front of the machine, and to deposit the same to the rear thereof.

Another object of the invention is to provide conveyer actuating means which may be readily applied to mining machines oi that type in which a carriage, carrying the cutting element, ,reciprocates at an angle to ln the drawings, Figure 1 is a top plan ot a portion of a mining machine equipped with the conveyer of my invention, parts being broken away and sectioned; Fig. 2 is a broken away, the cutting plane being passed through the compartment in which the conveyer is mounted; and, Fig. 3 is a vertical longitudinal section, the cutting plane being passed through the compartment in which the mining mechanism proper is mounted; parts being broken away.

Referring to the drawings, there is shown a main framework, or casing, comprising a hollow side member 1, and a compartment A. This casing is made up of an outside plate 3, constituting the outer Wall of the casing, and an yifnside plate 4, constituting 4 being united by a bottom plate 6 and a top plate 7. The end oftheccasing is provided with an opening 9- for a cutter head 10,

l sprocket. wheel 50.

the racl: frame 35, the sliding movement of the carriage may be reversed, and when the pinion #il is in mesh with neither the upper nor the lower portions of the rack frame, the carriage will not be actuated.

'lhe foregoing and preliminary explanation will serre to point out .to those skilled inthe ar t, the type of machine upon which the convcyer operating means herein disclosed, is adapted peculiarly to he' mounted. Passing now to a detail description of the conveyer operating means it will be seen that that end of the shaft 2G which is lo cated adjacent the outside plate B, carries a This sprocket wheel 50 is locatefwithin the contour of a sprocket chain constituting` a driving helt for operating certain mechanisms which will be described hereinafter. The uppermost portion of the periphery of the sprocket wheel 50 is adapted to engage theI upper portion of the sprocket. chain 5l, the sprocket chain 5t being carried about a smooth pulley 52, iournaled for rotation upon the outside plate. fl, adjacent the front of the machine. Another smooth pulley 52 is mounted upon the outside plate 3, adjacent the rear of the machine, and about this pulley 52', the sprocket. chain 51 is likewise passed.

Journaled for rotation in the plates 3 and It, adjacent the front of the machine is a. roller 55, a roller 5st being journaled for rotation, in a similar manner, adjacent the rear of .the machine. Upon the roller 54. a sprocket wheel 58, and this sprocket I wheel 53 is adapted to receive the sprocket chain 51. Sprocket chains 57 are passed about the rollers 54 and 55, there being sprocket wheels 58 upon the roller 54, adapt'- ed to engage the said sprocket chains. These chains are connected by blades 59, to form a belt conreyer. Disposed within the compartment l, and below the belt conveyor, is an inclined platform ($0, sloping downwardly, from the rear of the machine toward the front thereof` the rear end of thgplatforni being located below the pulley 52 and the roller 54. while the front end of the' platform is located below the pulley 52 and the roller The blades 59 of the belt eonreyer are adapted. to sweep along the platforui (30 from the front end toward the rear thereof. There is an opening G1 in the inside plate. 4t. located adjacent to the de-` pressed end of the platform GO, and serving as a communication between the compartments A and 1.

In practical operation. the dust and other incidental products produced by the cutter head l() will be receilved in the compartment 1 through the opening Gl. When the shaft 26 is rotated in the direction of the arrow B the sprocket wheel engaging Athe sprocket chain 51,'will actuate the rear roller 5l, causing 'the blades 59 of the belt con veyer to sweep along the platform 60, in the direction indicated by the arrows C in Fig. 2, the products produced by the cutter l0 being received by the blades 59 and carried upwardly along the`platform 60, to be deposited at the rear of the machine.

It may be noted that the shaft 26 is adapted to move transversely from one end of the slot 2T to the other, without impairing the operative connection between the sprocket wheel 50 and the sprocket chain 51; the transverse reeiprocation of the shaft 26 being carried on freely without stopping the conveyer. The antifriction member 52 serves to maintain the sprocket. chain 5l, in its upper portion, in parallelism with the slot 2T, so that the sprocket chain may at all times be properly engaged by the sprocket wheel 51.

From the foregoing it will be seen that the shaft 2G may have the necessary movement in the inclined slot 27, without in any way impairing theetciency of the shaftas a means for operating the conveyer herein described.

Ha ving th'us described the invention, what is claimed is 1. In a device'of the class described, a. casing; pulleys supported for rotation upon the casing; a driving belt passed about the pulleys; a conveyer operati-ing roller disposed below the pulleys and about which the belt is passed; and a shaft mounted for rotation and for transverse sliding movement parallel to that portion of the belt which is disposed between the pulleys, the shaft beingv operatively connected with the belt to drive the 'same upon rotation of the shaft.

2. In a device of the class described, a shaft mounted for rotation, and for transverse sliding movement at an angle to the horizontal; a wheel upon the shaft; a driving belt operable by the Wheel and within the contour of Whichbeltr the wheel is located; pulleys support-ing the wheel enfaging portion of the belt parallel to the plane of sliding movement of the shaft; and a conveyor operating roller about which the belt passes.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of t-Wo witnesses.
