MINING- PLN D LOADING APPARATUS.

Application filed January 10, 1923. Serial No. 611,711,

hfy invention relates to mining and loading apparatus wherein the main frame is held stationary while the dislodging mechanism operati `to mine coal from an upright mine wall for delivery to loading apparatus in psition to receive it adjacent the place of dislodgment, and one of the objects of the invention the provision of simple and improved apparatusof this character.

i further object of the invention is the provision of improved operating mechanism for that type of dislodging means which comprises dislodging tools which are rigidly connected to a supporting frame to move bodily therewith.

More particularly it is the object of the present invention to provide a system of hydraulic anclmring apparatus between the reef and floor and between the side walls of the nunc chamber to hold stationary the main frame for that type of mining machine wherein the dislodging tools are mounted on a supplemental frame to move bodily therewith relatively to the main frame.

Other objects of the invention will appear hereinafter. the novel features and combinations being set forth in the appended claims.

Fig. 14: is a plan View of Fig. 13; and

Fig. 15 is a diagrammatic illustration of the system of hydraulic anchor controlling mechanism.

By referring to Figs. 1 and 2 it will be seenl that to the rear end of the main frame 16 is connected an electric motor 175 the shaft of which carries a worm 18 which is in mesh with the worm gear 19. As shown in Fig. 9, the motor shaft 20 is keyed to the worm 18 and the worm gear 19 is integral with the gear 21, and both the worm gear 19 and the gear 21 are mounted on the vertical shaft 22, which in turn is mounted on the main frame 16. The gear 21 meshes with the large spur gear 23, as shown in Figs. 1 and 2. The spur gear' 23 is keyed to the vertical shaft 24 journaled in suitable. bearings 25 and 26 in the main frame 16. Secured to the upper end of the shaft 241 is an eccentric 27 for operating the feeding means of thedislodging mechanism hereinafter described.

The forward bottom portion 28 of the main frame is curved, as shown in Fig. 2, to facilitate sliding of the machine over the mine floor. Above the forward base portion 29 of the main frame is a cylinder 30 for receiving the plunger 31 of a hydraulic roof jack for anchoring the main frame. This hydraulic roof jack comprises a shoe having an upper serrated surface 33 and a lower bowl-shaped bottom 34 fitting into the dish-shaped recess 35 in the upper end of the plunger 31.

The cylinder 30 is provided with a cylindrical out-er surface to serve as a supporting standard and also as a cylindrical bearing for the hub 36 of the arm or supplemental frame 37 to which the dislodging mechanism is rigidly connected for bodily movement there-` with.

The hub 36 is provided on itsupper peripheral portion with ratchet teeth 38, as shown in Figs. 1 and 2. Surrounding the ratchet teeth is a ring 39 which carries a series of pivoted pawls 40 preferably extending approximately entirely around the hub 3G.

The pawl and ratchet mechanism is shown in detail in Fig. il. The pawls -lCO are pivoted to the ring 39, the same being spaced apart and arranged in series almost entirely around the ring 39. These pawls are each urced by its spring Lll into engagement with the notches between the ratchet teeth. lllhen the ring 39 together with the pawls carried thereby is oscillated back and torta by means oii the eccentric 2.7 the pawls 40 will move the hub 3G in feeding` direction when the ring is moved Vin la clockwise direction, and when the latter is retracted the pawls e0 will be permitted Vby the springs ll to ride over the ratchet into the next notches.

By referring to Fig. l it will be seen that the ring 39 is provided with a rearwardly ef:- tending yoke Ll2 which is provided with a rectangular opening e3, the side walls ot' which are engaged by the plate ill, at the center ot which is located the eccent le 27. rtherefore when the motor 17 isoperated to rotate the eccentric 27 in an anti-clockwise direction, as viewed in Fig. l, the plate te will be moved back and forth in the rectangular opening 43 in the yokefl2. llt the same time the plate #lil will be oscillatedL laterally which will eliect oscillation ont the yoke l2 and the ring 39, and when the latter is oscillated the pawls` lo will be moved 'forward `and backward to etlect continuous.forward rotation, step by step7 ot the hub 36 and therelo're ot the arm 37 and the dislodging mechanism mounted on the outer end ot this arm.

In order `to lock the arm 37 against retrograde n'iovement when the pawls et() are retracted a spring-pressed pawl 45 is mounted on the standard 46 which is secured at 4f? to the main frame 1G, as shown in F 2. rlfhis spring-pressed pawl l5 is similar in construction to the spring-pressed pawl l0 shown 1n Fig. 1l, but since the pawl 45 is mounted substantially on the main trame it acts an abutment to prevent. retrograde movement oft the ratchet ring 36 after the latter has been moved forward one step.

The dislodging mechanism is shown in Figs. 3, 5 and (3 as secured to the outer end or the arm 37 by `means oif the bolts i8 and 119. The dislodging mechanism may therefore be adjusted radially to various positions along the Varm 3T relative to the central upright axis ot the `bearing standard 30.

The dislodging mechanism comprises a trame 50 to which are rigidly attached the s littinoiand diecinOr tools 5l 52 that desiet: 12D C l ITD nated .5l being located at the floorj and that designated 52 being located midway between thetloor'and root in advance of the floor dislodging device 5l. `lint-fermediate the dislodging tools 5l and 52 are auxiliary piercing tools 53 for the purpose oit trimming oli they rlagged wall lett by the main splitting tools.

Lessors A t the door are additional trimming piercing implements 54e .secured rigidly to the frame 50.

' fit the upper portion of the 'trame 50 are spaced-apart rearwardly extending arms 55 and as shown in Fig. 3. To the rear ends oit these arms is pivoted at 57 (Fig. 6) an arm 58 which carries at its outer end the root splitting tool 59. Secured to the arm 5ta are root' trimming piercing implements 60, as shown in Figs. 3, 5 and 6. These rootl trii ming tools may be mounted on an auX- iliary arm Sl pivotally connected at 62 to the arm 5S so as to be adjusted on an axis at right angles to the radial arm 37. After the adj ustment is made the bolt 63 will be relied upon to hold the arm 61 in adjusted position relative to the arm 58. After the arm 58 has been moved to adjusted position the bolt tiel may be used in connection with a nut 65 to hold the arm 58 in adjusted position. llowever7 it is preferred to provide a hydraulic motor 6G comprising a cylinder with a piston (S7 therein and a piston rod G8 connected by a linl; 69 to the arm 5S tor adjusting the elevation of this arm and l0cling it in adjusted position.

Secured at T() to the arm 58 is an arcuate guide il which is adapted to move along the arcuate guideway d'2 for reinforcing the dislodging tool 59. Mounted on the arcuate oar 7l are wall trimming devices 73, as shown in Connected at 711, to the arm 37 is a spring '.75, as shown in Fg. 8. This spring 75 is adapted to engage an over-hanging downward extension 7G from the plate 77, as shown in Fig. 8. The plate 77 is mounted on top of the hub 3G and pivotally connected at 78 to the upper end oi the cylinder 30. rlfhe plate 77 of suilicient diameter to extend over a portion ot the ring 39, as shown in Figs. l and 2. 'lhe plate N is connected to the ring 39 by means of a plurality ot spacedapart pin and slot connections, as shown at T99 8O and 8l in Fig. l. connections may each be constructed as shown in detail in Fins. 13 and le. rl"he bolt 82 is secured to the ring 39 so that a washer 8st may rest on the loop-shaped seat- 85. rlhe collar 83 mav be guided along the slot 85 and the friction between the washer Sil and the seat 85 regi t x so that the plate may have a circumferential sliding movement relatively to the ring 39; Therefore when the spring tripping device engages the abutment YG the plate?? will be moved circumterentially relatively to the ring 39 a distance equal to the length of the slot 86 in the plate .7'7. This circumferential movement ot the pla'e FT to a limited extentrelatively to the ri Ag is for the purpose ot' operating a series et cams S one el which is shown enlarged in Fir` Thos cams ll. are located on the bottom of the plate 77 1n rlhese pin and slot in position to engage the inner lateral sides of the jack frames 173 and 174 so as to move the shoes 177 to 180, inclusive, against the spaced-apart walls of the mine chamber, after which the hydraulic motors comprising` the plungers 211, 212, fixed to the pistons 213, 214 in the c vlinders 215, 216, may he operated. The wall jacks will thus cooperate with the roof jack comprising the shoe 32, 33 in holding the main frame very firmly anchored during the operationof the dislodggingl mechanism.

The conveyer frame 117 may be pivoted to thebraeliet 185 which extends from one side of the frame. 16. As shown in 4, the wall jack 173 is tubular in construction to afford a passageway for the conveyer frame 11.7 which. may` be secured to the inner sides or wallsofthc frame 17 3. as indicated at 185, '186'. It should be noted that by reason of thepivotal connection of both the conveyer 1.17 and. the wall jack frame 173 the bolt 183 may he operated over a` suliicient distance to firmly anchor the shoes 177 and 178 against the side wall while at the same time maintainthe receiving end of the conveyer 117 in communication with the forward conveyor 110.

The wall ack frame 17 pivoted at 176 to the bracket 187 secured to one side of the frame 16. As shown in Figs. 3 and 5 rearwardly extending brackets 188 and 189 are connected to the rear end of the wall jaclr frame 174. These brackets are provided with screwthreaded openings to receive the bolts 191 and 192. TheseV bolts are in position to engage the roof and door, respectivelv. as shown in Fig. 5, so as to take the strain of the frame 174 from the spaced-apart ears 187 which extend from the frame 16.` 1t is preferred, however, to arrange the wall jacks 173 and 174, as shown in Fig. 3, so that both of the bolts 183 and 184 may be operated, thereby necessitating a` minimum amount of movement of the conveyer 117 and so that the latter may be maintained in accurate delivery communication with the forward conveyer 11.0. In addition to the wall jacks 173 and 174 there may7 be a rear jack 134 pivoted at 136 to a bracket 190 at the rear corner of the motor frame 17. A. roof jack 138 is connected to the rear end of the horizontal jaclr 134. lNhen the roof jack 138 is anchored and the wall jacks 173 and 174 are released the jack 134 may be operated to move the entire machine forward. During this forward movement `the wall jack shoes 177 to 180, inclusive, while not gripping; the side walls may be sufficientlyl close thereto to act as guides durinpr the forward movement of the ent-ire mining` and loading;` machine. During this forward. movement the forward roof jack 30 is, of course, released. luring the operation of the dislodging` mechanism while the forward roof jack is in anchored position and the wall jacks 173 and 174 are in anchored position, the roof jack 138 may cooperate with the jack 134 to assist the forward roof j acl; in resisting rearward thrusts exerted bj. the dislodging` mechanism.

At the rear end of the motor frame 17 is secured an upright floor jack 169 provided with a floor-engaging; shoe 193, as shown in l? 1g. 5. Bv controllingthe position of the shoe 193 the entire machine may,T be `guided therefor. liilhen the pump plunger 143 is reciprocated by the mechanism she-wn in Fig. 9 liquid may be drawn from the tank i and forced into the pressure supply pipe in accordance with the control permit xd bv the check valves 147 and 148. Bv means of the valve 150 the hydraulic jack 134 mav he If iven horizontal movements. butit shhuld be noted that the connections are such that when pressure is directed into the horizontal cylinder the roof jacl; 138 is atthe saine time operated to anchored position. 1When the valve 150 is in the position shown in his; 15 the pressure supply pipe 146 is connected to the cylinder 134 to the ri `shtof the piston 152. Villien the valve 150 is Igiven a quarter turn to the right by means of the lever the pressure pipe 15 connected to the cvlinder 134 to the left of the piston 152 and the pipe 154 is connected to the pipe 155 which leads to the exhaust pipe 156. 'lhercfore the roof jaclr 138 may be released and moved toward the right to a new position when desired. 'lhat is to sav, when pressure is supplied to the right of the piston 152 the roof jack 138 is anchored and the whole machine moved forward by operation of the horizontal jack 134. `When the roof jack 138 is released, the fran'ieworl: of the mining; and loadinev machine remains stationary and pressure exerted to the left of the 152 new position.

Hydraulic wall jacks may be pivoted to the sides of the frame 1G. shown in Fig. 3, at 137 and 194, the wall jacks beingdesignated 135 and 195, respectively. lll'iese wall jacks are provided with. wall-engaging; shoes 139 and 196, respectively. The control of these wall jacks 135 and 195 is illustrated in 15. By means of the valve 157 pressure from the pressure supplr7 pipe 146 may be will more the roof jack 138 forward to adirected to either side of the piston 197, the exhaust pipe being indicated at 198.

The wall jack 195 may be' controlled by thevalve 199 to direct the pressure from the supply pipe 146 to either side ot' the piston 200. The exhaust pipe is indicated at 201.

By means ot the valves 15S and 159 the hydraulic motor 66 shown in Fig. 6 on the dislodging mechanism may be operated to adjust the position oit the uppermost arm 58 and loclr the latter in adjusted position. That is to say, by moving the valves 159 and 158 to the positions shown in Fig. 15 supply pressure may be exerted on the piston 67 'to move the same upwardly while the pipe 202 is connected to the exhaust pipe 156. When the arm 5S has been moved to adjusted position the piston 67 may be locked in the cylinder 66 by closing the valves 158 and 159 so that communication through the pipes 202 and 203 may be cut oil' from either the supply pipe 146 or the exhaust pipe 156.

i By means oit the valve 160 hydraulic pressure may be exerted in the cylinder 30 ot the forward root jack of the main lira-me of the machine. The supply pressure medium enters the cylinder BOthrough the passage 161 to move the plunger 31 upwardly so that the shoe 232 will engage the roof ot the mine chamber. When the valve 160 is in the position shown in Fig. 15 the cylinder 30 is connected to the exhaust pipe 156, but when the lever 162 is given a quarter turn to the right the pressure supply pipe 1*-16 will be connected to the cylinder S0. Then this occurs the pressure medir-.m will Aflow from the pipe 163 into the cylinder 164L ot the accun'mlator 165, the latter comprising a plunger 166 having a collar 167 engaging a strong spring 16S. 1t is preferred to include the accumulator 1.65 in the system because the operation et the chslodging tools may cause such vibrations as to tend to eilect a yielding et the rootl or floor to the pressure of the forward not jack. llfhen this yielding action tends to take place the accunmlator will in'nnediately act to cause the Vplunger 31 to move the required distance to maintain a desired anchoring action even though the valve 160 may be moyed to such position to lock the plunger 31 in its rooien, iging position.

the upright floor jack 169 shown at the rear end et' the 'framework ot the machine in Fig. 5 may be controlled by the valve shown at. 170 in Fig. 15. lllhen the valve 170 is in the position shown in Fig. 15 the supply pressure der 169 above the piston 171 to thrust the plunger 93 downwardly and `thereby lift the rear end ot' the main traine on the curved bottom shown at 28 in Fig. 2, as a ulcrinn. By

giving the lever 204C a quarter turn to the right the upper end oit the cylinder' 169 will be connected to the exhaust pipe 156 and the supply pressure supply pipe will be conpipe 1-16 will be connected to the cylinnected to the cylinder 169 beneath the piston 171. The rear end oi the main trame can thus be lowered on the curved bottom as a vtulcrum. lVhen the inclination of the machine has been adjusted by means of the door jack 169 the valve 170 may be moved t0 such a position that the piston 171 in the cylinder will be locked in adjusted position, after which the plunger 193 may slide over'the mine lloor and act as a rear support for the mining and loading machine.

After the wall jacks comprising the shoes 177, 178, 179, 180 have been adjusted to positions against the side walls, the hydraulic.

motors 215 and 216 may be operated by the valve 217. `When the handle 218 is in the position shown in Fig. 15 supply pressure is exerted back oit the pistons 213, 21-1 to move the shoes 179, 180 to anchoring positions and at the saine time 'forcing the` shoes 177, 178 against the opposite wall. The shoes may be released by turning the handle 21S a quarter turn in` a clockwise direction as viewed in Fig. 15. The pipes 219, 220 are connected to opposite ends ol the cylinders 215, 216 to enable the valve 217 to control the plungers 211, 212. lt should be understood that Fig. 15 is a diagrammatic view showing the pipo connections between the various parts but. that in actual practice Vflexible connections are provided tor the pivoted hydraulic jacks, Such connections may be aii'orded by the Well unon'n metal pipes composed oi spirally connected strips and capable of withstanding high internal pressures and remaining water tight. i i

It desired, brackets 205, 206 and 207 may be connected to three corners of the tra-me 173, as shown in Fig. 3, and these brackets provided with bolts 208, 209 and 210, respectively, each similar to the bolt 192 shown in Fig. 5. j
