JOSEPH M. POWELL, 0F BROOKLYN, ENDEANA.

sHALE ruinas .AND nxcnvntroia.

Brooklyn, in the county of vMorgan and` State of Indiana, have invented a new andv useful Shale Planer andl Excavator, of which the following is a specification.

ln the manufacture of brick, drain tile, etc., natural deposits of clay, shale,'etc., are used as a basis for" the plastic. Such natural from top to bottom so that it is often desirable, and in .manyy cases absolutely essential for economical use, to mix the materials comingl from diere'nt portions of the de. posit. Heretcfore such deposits have been worked out in comparativelyfshallow depths either by hand mining or by the use of steam shovels, etc., and much labor has been required in yproducing `proper mixtures of the material. y

rEhe object of my present invention hase been to produce an apparatus capable of cutting the entire vertical face of a clay or shale bank under such conditions that a thorough and substantially yuniform mixture of the deposit may be automatically produced, the apparatus in operation taking the place of a very considerable number of laborers.

The accompanying drawings illustrate my invention. l

Figure 1 is a sideelevation of the apparatus in operative position; Fig. 2 an enlarged plan in partial horizontal section; Fig. 3 a fragmentary vertical' section on the line 3-3 of Fig. 2; Fig. 4 a fragmentary detail of the cutter chain; Fig. 5 a section on l detail of one side lof the putter chain and its adjacent g'uideway; and Fig. 7 a fragmentaryy detail of avrnoditied wearing shoe for theI cutter chain. In the drawings, 10 indicates .a track which is laid upon the ground at the bottom of the bank 11 and parallel with its verti.- cal face. Mounted upon the track 10 aretlie wheels 12 of a carriage 13 and mounted upon the carriage 13 is a main frame; or

14'which is slidably mounted upon framel 13 transversely of the track 10.

` Specification of Letters Patent. v Application filed August 5, 1912. Serial-No. 713,243. l

` upon the carriage notches 27 formed in the bit. embodies a tube or pipe 28 adapted to rc-' cent' cross pin 30.

The transverse adjustment of the tower 14v Patent-ed Jan. 6, 1914.

13 is obtained by means of a temper-screw crank 16.

Arranged at the lower inner corner of the tower 14 is a pair ofl idler sprockets 17 and vertically above these sprockets, at the upper end of the tower, is a pair of idler sprockets 18. Mounted in suitable bearings at the lower end of the tower14 is a shaft 19 which carries a pair of driving sprockets 21 which are arranged in the 'vertical planes of the sprockets 17 and 18,

Any one of a number'of kinds of cutters may 15 provided with a hand' n and over the three sets of sprockets is passed the cutter chain 22.v

be attached to cutter chain 22,` dependingvl upon the particular character of the deposit which is to be mined; but for ordinary clay or shale deposit l lind it advisable to use comparatively narrow cutter bits 23 each of whichY may be mounted in a holder 24 having a ytransverse opening 25 for the recep` tion of the' bit, said bit being held in any one of its possible positions by means of a f Holder 24 cross pin 26 taking linto one or the other of ceive a cross pin 29 connecting the pair of link belts forming the chain 22. Holder 24 at rear end is. provided with a notch or seat 30 which is adapted to receive the adja- Both preceding and following each cutter 23 I arrange a scraper 31 the purpose of which will appear.

The vertical face of the tower 14 is prc videdywith two vertical guides 32 for the recept-ion and support of the active portions of. chain 22, and said chain is provided at suitable points with wearing members to cooperate with the guides, such wearing members being anti-friction rollers 33, as shown in Fig. 4, or sliding shoes A34, as shown in Fig.

y7. Shaft 19 carries gears 41, 41 at its .opposite ends, and these gears mesh with gears 42, 42 carried byshaft 43. Shaft 43 carries gear 44 which meshes with gear 45 carried by shaft 46 which also carries a belt pulley 47 connected by belt 48 with a .clutch pulley 49 carried by shaft 50. Shaft 50 carries pulley 51 which is connected by a belt 52 withpulley 53 carried by the main shaft of motor 54. It is off course to be understood that the particular train of gearingand belting is merely typical, as indicating some suitable driving connection between the motive power and the cutter chain by means of which it may be driven at a speed suitable to the material being operated upon.

The shaft 43 carries a friction dlsk 55 which coperates with\ an djustable friction disk splined upon a shaft 57 connected by gears 58 and 59 with -a shaft 60 upon which is splined asprocket wheel 61 connected by a sprocket chain 62 toa countershaft 63. Countershaft 63 carries a pair of sprocket wheels from which run two chains 64, 64 in opposite directions to sprockets 65, 65 carried by axles 66, 66 to which the traction wheels 12 of the carriage 13 are secured, the arrangement being such that the traction wheels 12 may be driven at any desired speed in either `direction so as to transport the entire a Aparatus horizontally parallel with the working face of the bank 11. The friction disk 56 may be adjusted relative to disk 55 by an ordinary adjusting lever 71 the details of which are too well knownto re* quire description. Similarly, the d1sk 56 may be-moved into or out of operative engagement with disk y55 by an ordinary and well known operating. lever 72.

The active portion ofthe cutter chain, between the wheels y17 and .181s arranged within a verticall placed, U-shaped trough or chute,l 73 whic at its lower end, is provided lwith an upwardly inclined bottom trough 74 which is arranged arallel with that portion of the cutter cham which extends between the wheels'17 and 21. Arran ed above the trough 74 is a downwardly inclined plate 75 upon which the larger proportion of the mined material will fall and from which it will slide onto the receiving end of an endless delivery belt 76 which is extended from the outboard edge' of the tower 14 in such position that a tram car 77 may be placed beneath the delivery end of the belt. This tram car traverses a track 78 which is held parallel with track 10 and thecar is drawn along with the apparatus by means of a chain or other suitable detachable connection 79. Shaft 43 carries a sprocket wheel 81 which is connectedy by chain 82 with a sprocket wheel 83 carried by a shaft 84 which carries one of the rollers 85 upon which the endless belt 76 is mounted.

Adjacent the outside of each sprocket Wheel 17 I arrange a vertically adjustable shoe 86 which is 'carried at the lower ends by a pair of rods 87 connected by a rod 88 with a controlling lever 89 (see dotted lines lin Fig. 1) the arrangement being such that these shoes may be independently raised and lowered.

When the motor 54 is an electric motor, I provide a suitable feed wire which passes which contacts with a wire which may bel arranged along the top of t-he bank. It is convenient, wlth such an arrangement, to provide the feed wire with suilicient slack to permit the placing of a weighted pulley block 94 in the bight of the slack.

The operation is as follows : Tracks 10 and 78 being held adjacent the bank 11 4in the manner indicated in Fig. l, the tower is adjusted transversely ofthe carriage 13 until the cutters 23'project a suiiicient dis-l i tance into the vertical face of thebank 11, whereupon the apparatus isputy in motion and the cutters move downwardly across the face of the bank 11 and at the s e time the carriage 13 is advanced slowly a on the track 10.I Comparatively narrow an shavings of mud or shale are thus cut, from the face of the bank and, as several cutters are simultaneously in operation at different heights ofthe bank, it will be apparent that the cuttings will fall in a substantiall uni form mixture upon platform 75 and e de livered by carrier 76 to' the car 77. The intv terial which gets below the platform 75 is carried by the Scrapers 31 up the trough and delivered tov the carrier 76. During the adthin 1 vance of the apparatus ,along` track'lO that shoe 86 which is advanced will be raised while the rearward shoe 86 will be in its lowest possible position thus carrying along the cuttings which may have fallen that low so that the will be gathered up by the Scrapers and de ivered to the carrier.

I prefer to make the cutters, 23 comparatively narrow because it is quite common to findv stones embedded in the clay or Shaka.

and if the cutters are narrow no difficulty is experienced in breaking up such harder material. l

After the entire apparatus has traversed a sufficient length of the bank the wheel 56 is shifted to the opposite side of the center of wheel and the operation is repeated with the carriage 13 moving in the opposite direction. From time to time, as the need arises, the tower is moved transversely of the carriage 13 toward the face of the bank. l

I claim as my invention: y A machine for comminutin and'mixing ous operation from top to bottom upon the face of the bank, means for driving said carrier, means cordinated with the carrier f driving -means for simultaneously driving this' 3rd day of August, A.
