SPECIFICATION formingpart of Letters Patent No. 748,530, dated December 29, 1903.
Application filed November 21, 1902. Serial No. 132.617. (No model.) I
The simple and novel construction em-` ployed by us in carrying outourinvention is fully described and claimed in this specification, and illustrated in the accompanying drawings, forming a part thereol",in which- Figure 1 is a perspective View Of our machine. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal section of the same. Fig. 4 is an end view of the same. Fig. 5 is a detail of the auger. Fig. 6 is a detail of the stop-plate.
Like numerals of reference designate like parts in the dierent views of the drawings.
The numeral l designates a carriage comt prising a bed 2, mounted on wheels 3. The
Wheels 3 have flanges 4 thereon to adapt them to engage a track formed of parallel rails 5. The bed 2 is constructed of iron and supports the working parts of our device. Al shaft 6 extends transversely the bed 2 and is supported by boxes 7 bolted thereon. A large gear 8 is mounted onfthe shaft 6 and meshes with a smaller gear 9, keyed on a shaft 1 0, journaled in boxes 11 and slotted at 12 to accommodate an auger 13. The auger has a broad Hat shank 14, which fits the slot 12, and a long screw 15, which tapers'uniformly from the junction with the shank 14 to a point 15a. The spiral edges of theauger bear V-shaped teeth arranged alternately, which serve to cut the clay.
To propel the machine, a bevel-gear 17 is keyed on the shaft 6 and meshes with a bevelgear 18, keyed on a shaft 19. The shaft 19 is jourualed in bearings 20", formed in the upwardly-extending arms'20a of a voke 20, rigidly bolted on thebed 2, and is threaded at 21 throughout the greater portion of its length to adapt it to engage a threaded aperture .22,
formed in a stop 22, adjustably mounted in a longitudinal slot 23a, formed in a post 23. The post 23 is provided with an adj ust-able head 24", carried by a screw 24, operated by a lever 25. The head 24' engages the roof 26 of a stope or drift. 4
To drive the shaft 6 to propel the machine and to operate the auger 13, two levers 27 are provided and have forked heads 2S, which straddle the shaft 6 and carry hooked pawls 29, which engage ratchets 29, keyed on the shaft 6. secured to the carriage, serves as a buffer to keep the carriage from catching the wall.
In using our machine the post 23 is first set up and the head 24a raised to engage the roof 26. The track is then laid and the shaft 19 placed in position. The auger 13 is then forced into the gouge, and the levers 27 are loperated to drive the shaft 6 to drive the shaft 19 to pull the machine ahead and to actuate the auger to cut away` the gouge and undermine the coal-vein. l v
We do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of our invention.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In a mining-machine, the combination of a carriage oonstructd tov run on a track, ashaft mounted transversely said carriage and bearing a bevel-gear and two ratchets, a yoke mounted on said carriage and having upwardly-extending apertured arms, a post having an apertured threaded stop mounted thereon, a screw journaled in the said apertured arms and engagingsaid threaded aper-` ture in said s top and bearing a bevel gear meshing with said bevelgear on said firstme`ntioned shaft, and twolhand-levers bearing hookedpawls engaging; said ratchets to Operate them to drive said screwsubstan tially as described.
2. In a mining-machine, the combination of a carriage, a track fors 'd carriage, ashaft mounted transversely said-carriage and bearing a bevel -gear and two ratchets, a yoke mounted on 'said carriage and having upwardly-extending apertured arms, a screw- A wheel 30, carried by an arm 3l,
