MAGHINEIRY' FORCONTINUOUSLY CUTTING COAL.

SPECIFICATIFON forming part of LettersPatentNo. 753,092, dated. February 223, 1904. Application ledISeptemher 30, 1902. Serial No. 125,430. (No model.)

of production; and with this object in view the invention consists in the machinery hereinafter described, the particular points of novelty in which are afterward specifically suitable motor,the eccentrics will draw the claimed. l

In the accompanying/drawings, in 'which I have illustrated' machinery constructed in accordance with my invention, Figure l represents in plan view machinery in position for operation. Fig. 2 represents in elevation that portion of the same contained in the forward part of the tunnel in which the driving mechanism is located. Fig. 3 represents in plan viewmachinery in which the rope carrying the cutting-tools is arranged for continuous operation in one direction. Fig. 4 represents in elevation the means for governing the tension of the rope carrying the cutters and feeding the cutters into the cuts as they progress.

Like letters indicate the same parts where they are shown in more than one 'dgure of the drawings.

Referring to the drawings by letters, a, indicates a rope or cable carrying cutting-tools o. Posts are temporarily erected in the tunnels, as at c c', consisting of blocks g g', Fig. 2, rigidly held against the top and bottom of the tunnel 3 by right-and-left screw g2, and the rope is passed over guide-pulleys t It', mounted on the blocks gand under guidepulleys on the blocks g', one of which is shown in dotted lines in Fig. Q- at a', and around pulleys y' j', making an endless belt of the cutterrope passing across the breast at two levels, one in the plane of the top of pulleys t fr and the other in the plane of the bottom of the pulleys i.

on opposite sides of the pulley and set diametrically opposite to each other on the shaft. To the strap of eccentric e is attached a cable 22, which passes over a guide-pulley 7c, mounted on a temporary post Z, and is attached to.

the shaft of pulley j', While a cable 21, attached to the strap of eccentric e2, passes around guidepulleys f f f and over guide-pulley c,mount ed on a temporary post Z, and is attached to the shaft of pulley j. Thev pulley f may be actuated in the direction of the arrow f3 in order to keep the rope a taut and feed it and the cutters into the cuts as they progress.

When the driven pulley 0l is actuated by any pulleys y' j alternately, and as one of them is drawn in one direction the other moves in the opposite direction, thus reciprocating the cutter-rope a across the breast and making two cuts at the same time, as indicated at m m in Fig. 2. A

In the construction illustrated in Figs. 3 and 4 two cuts are made at the same time, butinstead of reciprocating the rope it is moved continuously in the same direction. The rope a is of the same construction as in Figs. 1 and 2, carries cutters and is carried around a pulley cw at one side and a pulley @2 at the other side, thus forming an endless belt which passes over guide-pulleys fnn, mounted on top blocks 0 o of a temporary post and under guide-puh post, one of said blocks and pulleys being shown at 02 and p3 of Fig. Li, one side of the rope passing across the breast on the level of the top of pulleys n a and the other on the level of the bottom of pulleys 293,. making two cuts at once, as in the mechanism shown in Figs. 1 and 2. The pulley am ismounted on a shaft p on a truck fil", which shaft also carries another pulley driven by means of a belt t t from any suitable motor, (not showin) said belt being guided by pulleys a a'. The pulley 62" is mounted on a shaft p on a truck 7b2, carried on wheels 71,3", on which truck therel is a drum g, upon which may be wound a rope g by means of a crank g2, said rope q being secured to any suitable fixture, (not shown,) so that by winding up the rope on the drum during the operation the endless-belt rope a may IOO be governed as to tension and fed into the cuts as they progress. In this construction the rope a moves continuously in the same direction.

The operation ofthe machinery will be readily understood from the foregoing, and as the cuts progress and bring the front or cutting portions of the cutting-rope too near t'o the guide-pulleys the temporary posts may be removed and placed farther back in the tunnels. l

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In machinery for cutting coal, the combination with temporary posts in the side tunnels and upper and lower guide-pulleys carried thereby, of pulleys in the rear of said guidepulleys, an endless belt of rope carrying cutters, passing over the upper guide-pulleys and across the breast on the level of the top of said upper pulleys, under the lower guide-pulleys and across the breast on the level of the bottom of said lower pulleys, and around the rear pulleys, and suitable driving and feeding means whereby the cutter-rope makes two cuts across the breast at the same time, substantially as described.

2. In machinery for cutting coal, the combination with temporary posts in the side tunnels and upper and lower guide-pulleys carried thereby, of pulleys in the rear of said guidepulleys, and suitable driving and feeding means whereby the cutter-rope is driven continuouslyin the same direction and makes two cuts across the breast at the same time, substantially as described.

3. In machinery for cutting coal, the combination with temporary posts in the side tunnels, and upper and lower guide-pulleys carried thereby, of a truck in one tunnel, a shaft thereon, a pulley on said shaft, Va second truck in the other tunnel, a shaft thereon, a pulley on said shaft an endless-beltrope passing across the breast at two levels, over said guide-pulleys and around the truck-pulleys, a driven pulley on the shaft on the rst-named truck, a drum on the second truck, and a rope winding thereon and adapted to be secured at its end, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
