vMy invention relates to mining machinesy tween adjacent mine chambers to provide brefalr-throughs for the purpose ,Gf Ventiparticularly it is the object of the presentinvention to provide improved end e' cient .means for boring bei@ et vals through a partition 'in a lmine' chamber y such chambers for the purpose `of ventilating the space whe-re mining operations are .being carried on.

A further object of the invention is the provision of mechanism for boring holes in Aa nomine wall combined with a coal mining and loading machine with provision in common with the 'latter and the boring mechanism for taking care of the cuttings pio duced :by the mining Amechanism as weli as 4 boring mechanism.

Another object ofthe 'invention is the provision of 4mining mechanism including vent-ilating apparatustherefor and means for formii f passageways 'through which the .ventilating mechanism may operate in .proximity to the mining mechanism.

Other objectsof the invention will appear hereinafter, the novel features and combi-na# tionsbeing set forth in the appended claims.

Referring to the .accompanying drawings,

Asshown in Figs. 1 and 2, .the base frame 8 is provided .with spaced-apart upright .Standards 9 adapted to be anchored .by means of roof jacks 10. Pivoted to the .upper :ends of rthe .standards 9 is a mein means for drilling frame `11 to which is pivoted a screw-threaded rod` 12 on which is mounted a whee'l'l?) 'for engaging the arm 1e to vary the inclination .ofthe `main frame 11,`togethe r with the parts mounted thereon. i

" At theforward end of the main frame 11 is a loop chain core-cntterl adapted to 'be `'ev-.ndrlg on anv upright anis whilepulling into the mine wall the ,belt r16 as shown' Fig. lAfter vthe core has been cnt a pull `lis exerted on the rear end of the belt A16 to break the core material against ythedrum 17, as shown iny dotted lines in Fig. 2. By continued pull onthe belt 16 Ithe cnt-out ina- 'teriai is delivered to the conveyer i18 for delivery .to the rear end -19 of the mining and loading machine. V

A motor 20 is geared to 'the shaft 21 on which are mounted `the worms yE22, 23 and 24. VEhe worm 21C lmesheswith `the worm gear 25 for operating the rope drum 26 so thatthe rope 2T may ybe pulled to effect feeding of the loop chain core-cutter 15.v The wor-fm QA- meshes with the worm gear 28 so Vas to operatefthewinding drinn 29 on `which the belt 16 is wonnd. iAs shown in 1, the worm gear 28 is connected to the cli-nm 29 `by'means 'ofthe clutch 80, whereas the rope drum 26 is Vconnected to the worm gear 25 by means: of the clutch 31. The worm 2B meshes with the worm gear '82 at the -upper end of the shaft 33. By means of a clutch 34 the worm gear 32 is 4connectedto the A shaft 33 to drive the lat-ter so to transmit motion' vto the ,sprocket vat *the lower end of `v,the shaft 53. This sprocket mining and Iloading machine. The last- A,

named sprocket is connected `by a vertical shaft v36 -to the sprocket 317 which meshes wit-h the main-conveyer chain 1,8. 'The zlatter extends .around the sprocket at the vfer- Award portion of the main frame so as to drive the gear 38 which transmits power :to the chain cutter 15.

The ,conveyer chain 18 is provided with lateral extending flights 39 `which move along a ltrough 4.10 the 4forward end of which is inclined, as shown at 41 in A1, so as to provide van inclined surface, arcuate in plan, for the cuttings 'from .the chain V1nerf- 'cutterto move over into the trough 40. The chain cutter 15 isnpreferably so cperated as to have the emerging run at the lower side and thus cause the cuttings to be moved over the surface 41 into the trough 40 where such cuttings will be gathered by the flights 39 and moved towardthe rear end of the machine, together with thc coal which is dislodged from the mine wall.

The type of mining and loading machine may be similar in construction. and operation to that disclosed in my Patent No. 1,325,031,`

granted December 16, 1919, for an improvement in mining` machines, although other types of machines may be used so far as the use of drilling mechanism and Ventilating apparatus in combination with a mining and loading machine, is concerned. The present application is a continuation in part of my co-pending application, Serialllo. 296,867, tiled May 13, 1919, as a division of Serial No. 764,487, filed April 30, 1913, loading machine, since in said divisional application .boring mechanism is shown mounted on a mining and loading machine for producing break-through passages in the manner illustrated in Fig. 3 of the accompanyingdrawings. I prefer, however, to mount the boring apparatus on the mining and loading machine in such a manner as tio deliver the cuttings from the drill to the conveyor which takes care of the cuttings from the chain kerf-cutter 15, as well as taking care of the material which is dislodged by the mining mechanism.

The drilling mechanism for boring the holes 42 shown in Fig. 3 comprises a drill 43 mounted in a semi-circular trough 44 having a cylindrical outer end 45. as shown in Figs. Y2 and 4. The trough 44 is provided on its under side with an inverted T-shaped head 46 (Fig. to forma sliding tit with the spaced-apart grooves or guides 47 on the pedestal 48. By reason of the dovetail connection between the trough 44 and the pedestal 48 the trough may be adjustably positioned relative to the framework of the mining and loading machine so as to make a close lit with the mine wall, as illustrated iny Fig. 3. This will enable the cuttings produced by the drill 43 to enter the trough 44 and on account of the spiral blades of the drill, the latter acts as a spiral conveyer for conducting the drill cuttings away from the mine wall along4 the trough 44 out of the end 49, from which the drill cuttings are deposited into the path of the flights 39 of the conveyer 18. f

After the trough 44 has been moved against the mine wall, as shown in Fig. 3, it may be secured in adjusted position by means of the set screw which is operated by the wheel 50.

The lower end of the pedestal 48 is provided with a disc 51 which fits into acircular groove in the bracket 52 and therefore the trough 44 may be adjusted angularly on an upright axis which is located at the center of the disc 51. After such arcuate adjustment has been made the drill, together with the trough 44, .may be secured in adjusted position by means of the set screw 53 which is operated by the wheel 54.

The bracket 52 is secured to the plate 55 which is provided with a slot 56 so that by means of cap screws 57 extending through the plate 58 the drill may be adjusted in position lrmgitudinally of the main frame of the mining and loading machine. rEhe Vplate 58 is secured to the main frame, as indicated at 59 in Fig. 2, and at 60 is secured a bracket 61 through which extends a" screw-threaded rod. 62 having a wheel 63 at one end, the rod 62 being threaded Vthrough the bracket 52. l`herefo1e,"l$ y loosening the cap screws 57 and'operating the wheel 63 the bracket 52,

together with the drill and the trough, may l be moved along` the plate 58 for adjustment longitudinally thereof. position the cap screws 57 are each operated to securely fasten the plate to the frame 58.

in order to rotatie the drill an electric motor 64 mounted ou a bracket 65 isconnected by a train of gearing 66 to the shaft 67 which is journaled in the bearing 68 mounted on the bracket 65. The shaft 67 carries a socket 69 into which lits Vthe squared crd 70 of the drill 48. The bracket 65 is provided with spaced-apart inner grooves 7l- 71 which tit over the guide langes 72, 72 at the sides of the trough 44 so that the motor 64, the drill 43, and the power transmission -mechanism between the motor 64 When in adjusted and the drill 43 may all move as a unit bodily along the trough. 44 while being' guided by the lateral Hanges 72 of the trough.

ln order to feedthe drill one of the anges 72 is provided with rack teeth 73 with which i'neshes a pinion 74 at the lower end of the vertical shaft 75 which is journaled in the bearings 76 and 77, as shown in Fig. 7. The bearing 77 is connected directly. to the bracket- 65 and the bearing' 76 is connected'to the casingp 7 8 which in turn is rigidly connected to the bracket 65. It will thus be seen that the bracket 65 constitutes a housing and a supporting frame for the mechanism which `rotates the drill and also the mechanism which feeds it.

As shown in Fig. 7, the motor shaft 79 is provided with a worm 8O which meshes with a wormr gear 81 on a sha-tt 82 mounted in the bearing 83 attached to the 'door of the casingv 7 8. Loosely mounted on the shaft 82 are spiced-apart bevel. gea- rs 84 and 85 between which is a double clutch 86 which may be operated by means of a lever 87. rlhe bevel gear 85 is somewhat larger in diameter than the bevel gear 84. The bevel gear 85 meshes with a horizontal bevel gear 88 and the bevel gear 84 meshes with another horitill motor 64 to drill another hole through the mine wall, and while this drilling is taking place the cuttings trom the drill are beingdelivered to the conveyer which is in operation. It will thus be seen that drilling is effected at the same time that the mining operations are carried on and the cuttings Jfrom the drill are taken care of by the same convcyer which takes care ogt the cuttings from the hert-cutter. As soon as the mining operations are completed everything will be in readiness for mov-ement ot the mining and loading machine as a whole to a new location because by that time av hole has been drilled through the mine wall and the cuttings have all been removed. As soon as the mining machine is moved to its new location and anchored the ventilating apparatus may be connected to the hole which has `been last drilled and a plug used to close the opening to which the ventilating apparatus was previously connected.

Obviously those skilled in the art may make various changes in the. detailsl and arrangement of parts without departing from the spirit and scope ot the invention as deined by the claims hereto appended land I wish therefore not to be restricted to the precise construction herein disclosed.
