T0 all whom it may concern,.-

Be it known that I, EDWARD OTooLE, a citizen ofthe United States of America, residin g at Leisenring,in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Mining-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in mining-machines, and is particularly adapted for use in mining coal or other mineral substances.

The object of my invention is to construct a machine of this character with a pair of cutter chains operating in opposite directions and with means for imparting an oscillatory movement to the said chains during their operation.

Briefly described, my invention comprises a suitable frame carrying gears upon which the cutter-chains are trained and operated by a segmental rack and worm for imparting the oscillating movement to the cutter-chains and suitable operating means for the said worm and gears, all of which construction will be hereinafter more specifically described and then particularlypointed out in the appended claims; and in describing the invention in detail reference will be had to the accompanying drawings, forming a part of this specification and wherein like numerals of reference indicate like parts throughont the several views of the drawings, in which* Figure 1 is a side view of my improved mining-machine. Fig. 2 is a top plan view thereof. Fig. 3 is a transverse vertical sectional view taken on the line 8 3 of Fig. 1. Fig. 4is a detail perspective view of the supportingshaft-s for the gearing. Fig. 5 is a detail perspective View of the vertical supporting-shaft for the gears upon which the cutter-chains are trained. Fig. 6 is a cross-sectional view taken on the line 6 6 of Fig. 7. Fig. 7 is a top plan view of a part of one of the guides for the cutter-chain, showing the latter therein. Fig. Sis a horizontal sectional View of the clutch-gearing for the worm. Fig. 9 is a perspective view of the clutch-operating lever.

Referring to the drawings by referencenumerals, l indicates a base, upon which is mounted a pair of inclined standards 2, having bearings 3 on their upper ends, in which is journaled the horizontally-extending rockshaft 4, provided on each end with a tenon 5, these tenons extending outwardly beyond the standards 2. Upon the rock-shaft 4, between the standards 2, are mounted mitergears 6 7, the former keyed to or secured to the rock-shaft bya vcollar 8, the latter having a collar 9, which is connected t-o a pinion 10, mounted on said rock-.shaft 4. The side bars l1 of the frame are mounted at their forward ends on the tenons 5 of the rock-shaft and are rigidly secured thereto, and at their other ends these side bars of the frame carry vertical shafts 12, extending above and below the said side bars, and upon which extending ends are mounted the upper guide l4and the lower guide 15 for the endless cutter-chains. Mounted within these guides, near the ends thereof, are sprocket-wheels 17, over which the cutter-chains 18 are trained, said chains operating through the guides lengthwise of the same, with only the cutting-teeth of the chains extending beyond the outer face of the guides. For this purpose the guides are each provided with an elongated runway 19, extending from end to end of the guides and terminating in the outer face of the guides in a groove 20, through which the teeth 18 of the cutter-chains 18 travel during the travel of the links of which the cutter-chain consists through the runway 19. The upper of these cutter-chains is trained over its sprocketwheels in the guide 14 and a sprocket-wheel 21, which may be either formed integral with or secured to a ruiter-gear 22, rotatably mounted on a vertical shaft 23. This vertical shaft 23 is centrally secured to the horizontal shaft 24 and has rotatably mount ed thereon, below such shaft 4, a miter-gear 24, having formed integral therewith or secured thereto a sprocket-wheel 25 to receive the lower endless chain, the latter operating over said sprocket-wheel in its guide 15. The miter-gear 24 is held against displacement upon its shaft either by keying or by means of the collar 2G, while the miter-gear 22 is likewise held against displacement either by keying or by thef'collar2fZ. Thesemitergears 22 2'4 mesh lwiththe ruiter-gears 6 jand 7 on the rock-shaft 4, so that when motion is communicated to the gear 7, by reason of its connections with the pinion 10, the gears over which the chains .are trained will be. operated simultaneously. "Anoscillatory'ori up-and-down movement is imparted to the cutter-chains by means of a segmental erac'kg 28, the ends of which are rigidly connected to the ends of the shaft 23. This rack is' adapted to engagea woriniforimpartinglthe oscillatory movement to the frame and cut-F ter-chains, as will .nOWbe'deS'cribed The base 1 has mounted thereon, besides the inclinedstandards2, a pairlofyertical sandardsi29, fin which fis journaled la shaft: 30, shaving :a vpinion 31 y'mounted thereon to; mesh with `the vpinion lO'andWiththeldrive-l pinion 32. ABearings'33 are mountedzon 'the upper ends'of these standards 29 Iand havej: journaled 'therein a shaft 34, upon which is mounted to mesh with the'pini'on3la pinion 35, so that this shaft may be driven simul-f faneously with `the shaft-30. This shaft 34, has loosely mounted thereon a pairofmiterf gears 36 37, each havingfclutch-ibushingsfal-i ternately engagedr 'by Athe `'clutchsleeve -38,y arranged upon the shaft 34 .fand :adapted toi be shifted longitudinally Vupon such shaftg so as to lalternately engage A'the clutch-'bushy ings of the miter-gears. This-clutchsleevef`v 38 is `provided with a peripheral Iflange f39, which -is adapted -to .be'engaged bythe-shift-z ing vpin or finger 40, `mounted at 'theupperf end of lthe segmental rack, and -byiashifting fork 41.

`Mounted upon the 'base l is a shaft 42,'i which has rotatablyse'curedfon-itsupper endl a Worm 43 foren ga gementwiththesegmentals rack 28 and carriesa Ybevelforimiteirgear 43"? for engagement with the'miter-'

gears

36 and 37.

The Iframe is strengthened by connecting braces 44 and 45 -tothe-upper and'lower ends of the rock-shaft Vv23 and upper fand lower; Cutter-'chain guides, respectively.

The operation of thefdeviee is as =follows: The drive-pinion 32 `being operated, '

motionf isimpartedltothe pinions

3l, 35, and 10, re-f vol-.ving the bevel-gear`7 and operatingge'ars` 22 24, the said gears 22 24 operatingfinoppo sitedirections and imparting lthe samefmof tion -to the cutter-chains 18, the sprocketsI mounted 4upon the gears `22 24 fcausing'thel operation of the 'cutter-chainsl'S. Simultaneously with the operation of the'cutter-'chainsi the Worm 43 is rotated, which,1meshi'ng1withl the rack 28, will give an oscillating fmove= ment to '.theframe,carryingftheicutter-ehains in the samedirectionfand =if 'the movement? of the lframe :is in the :upward direction the same Will'continne until Athe shifting Apin lat' the'head of the rack Acomes into'engagementf with the flange 39 of the v'clutch-'sleeve con-y necting the gear 37 and:causingthe-samefto rotate the worm l:in an opposite-direction,rim-i parting the downward movement to the frame. Vhen the frame has freached the limit of its downward movement, the handle 4l is operated, causing the shifting fork to move'the clutch-sleeve in the opposite direcltion and reversing the movement of the frame.

lItisthou'ght that themany'advantages of my improved mining-machine can be readily Vlunderstood from the foregoing description,

taken in connection with the accompanying drawings, and it will be noted that various :changes may -be -made yin .thedetails of construction without departing from the general spirit 'off my nverti'on.
