Bedtkriown-th'atd, ANDREW Powe-LL, a citizenl of' the United States, l.Uniontown',1in th'ejeounty of' Fayette and *Stateiof' Pennsylvania, have invented cer- KAVMin-ing Apparatnsgiof which the following rlage with the punch support removed.

i residing at tainnew .anduseful Improvements inv Coalis a specification.: "1

lhls' invention=relates to the class of mining machines, and pertains espec'iallj7 to ay coal mining apparatus.

The object of the invention is to provide novel and peculiarconstruction and arrangement of parts in a coal mining apparatus, as will be hereinafter fully described and pointed out in the claim.

In the accompanying vdrawings forming part of this application: Figure 1 is a side elevation of the apparatus in position for operation. Fig. 2is a top view of the car- Fig. 3 is an end view of the carriage with the rear truck removed. Fig. 4 is a detail side elevationofthe rear portion of the carriage.-

The same reference numerals denote the same parts thrfnlghout the several views of the drawings. y' -4 The carriage comprises suitable wheels 1, axles 2, and sides 3 having braces 3a. The support for a punch 4, consists of tour uprights 5, working in' brackets 6 secured to the sides 3, and having a rack?, engaged by a pinion 8,v having a pawl 9, for sliding the uprights 5 when a suitable crank-handle is applied to the stem 5a; vthe uprights are braced by bars 10, having one end pivoted to the sides 3, and the other end is adjustably Secured to the uprights 5 by bolts 11 and apertures 12; a bed 13, upon which the punch is operated, is carried by rods 14 at the top of the uprights, and such bed has anglerons 15 resting on t-'he rods 14 and'con nected by tie rods 16. One pair of the uprights is shorter than the other or rear pair, for the purpose of inclining the punchdiedv relatively to a body of coal A. The up-. rights are held in adjusted position by stoppins 17 engaging holes 18 and the top edge of the sides 3.

A conVeyer-frame 19 having sides working between the sides of the carriage is sus- 'iinas 21, and thefmneed @f Said? thereof being hung c lose pended fro'm the carriage sides 3, between the wheels 1, by means of a shaft 20, and

providedk with' wheels theffront than the other pa1r,to'prov1dej forfftlie'nelined position of tbefranie. The'f nt -edgev of the lframe `sprocket wheels 23, and vt'lfe'rear end th r has sprocket wheels 2 4ff`I`liesejwhe'elsop-l erate endless sprocket'chai'iis25 'whi'clr`c`-ai'1y the conveyer 26. The front? endA of 'thefoni 9l "is "provided veyer frame 19 may be raised :or sw'u'ngon' the shaft 20, andI held jliisuch' positi'nby means of hooks 27 depel'idihg on the lcarriage sides 3 and engaging eyes E28 on the frame 19. This is desirable especially in moving Vthe apparatus from one position to another on a track B Each side of the front end ofthe frame 1S) is provided with wings 29, hinged at 30, and supported in raised position by legs 31. These wings form a platform for the coal' as it falls from the coal body A. When the Wings are in horizontal position for the lirst dropping ot coal thereon, the coal is shoveled or pushed from the platform onto the conveyer, but after suiicient 'coal has been removed from said body, the wings may be unfolded at. their hinges and. supported at an angle to the frame 19 by their legs 31.

A truck 32 is connected to the rear end of the carriage by means of a pair of hars 33 on each side, and this truck is provided with standards 34 having apertures 35. An elevating eonveyer frame 36 is pivotally hung at 37 to the truck 32, and may be adjusted to vary its incline by bolts, rods or pins 38 extending through the apertures 35 to'holdl the frame in adjusted position.

The frame 36 is provided at its upper end with a discharge chute 39 and thebot-tom end of this frame has a projecting leaf 40 adapted to extend `under the rear end of the conveyor 26.

The ends of the fra-me 36 are provided with sprocket wheels 41 and 42 respectively for endless chains 43 of the elevating conveyer 44.

A double crank shaft 45 is journaled in bearings' 46 .upon the rear end of the carriage, and may be operated by any suitable motive power, but for the purpose of illustration, the shaft is shown operated 'by two compressed air engine cylinders 47. Each end of this shaft is provided with two sprocket l wheels 48 and 49 respectively. The wheels 48 impart motion to the carriage through a sprocket chain 50, and sprocket wheels 51 lon the rear wheel axle 2, and the wheels 49 ,impart motion to the conveyers through run under such body; that the punch may be operated from such point of coal removal upward for an unusual distance as afforded by the adjustable punch support; that the conveyer 44' carries coal direct from the con- -veyer 26 to the chute 39; and that the chute end of the conveyer 44 may be adjusted as desired, especially to suit pit cars of various heights, by simply swinging the conveyer 44 on its pivot 37 Having thus described my invention what I claim as new and desire to secure by Letters Patent 1s:

In a coal mining machine, the comblna- 'tion of a carriage having open ends and closed sides, a shaft crosswise under the carriage, a conveyer framepivotally mount ed on the shaft so as to be free to .swing in respect thereto, links pivoted to the sides of the carriage and connecting the ends of the shaft therewith "so that the shaft may have swinging movement, and sides secured to and projecting upwardly from the said frame between the carriage sides for closing the space between the carriage sides and the said frame when the latter is Aswung below the carriage.

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

ANDREW POWELL.
