To all whom it mayconcem: 7

Be it known that we, FRED A. GnrnoLns and EMIL E. MARTINSON, citizens of the United States, residing at Globe, in the county of'Gila and State of Arizona, have invented certain new and useful Improvements in Huck-scooping Apparatus; and we do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to muck scooping apparatus and itconsists in the novel features hereinafter described and claimed.v

An object of the invention is to provide apparatus of simple and durable structure adapted to be used in mines, stopes and drift shafts for scooping muck and depositing. the same in a car or other receptacle preparatory to its removal from the mine or shaft.

With this object in view, the apparatus comprises an arch bar adapted to be placed in the mine or shaft with its legs at the opposite sides of a track or roadway. A car is adapted to move along the track or roadway and may be of usual pattern. An I-beam is pivotally connected with the upper intermediate portion of the arch bar and a longitudinally extensible prop is mounted at the free end of the I-beamand is adapted to be engaged with the sides of the drift or shaft. A carriage is mounted for movement along the I-beam and is provided with stop devices which may be engaged in notches provided in the beam, whereby the carriage may be stopped at suitable points along the beam. A block is detachably mounted in the carriage and a releasing means is provided which may be manually manipulated for detaching the block from the carriage. A scoop is connected with the block. A cable is trained over pulleys mounted upon the carriage and under a pulley mounted upon the block and is connected with the carriage. The said cable is trained around a pulleymounted upon the prop and the end portions of the said cable are arranged to wind upon drums which are mounted upon a vertically dis posed prop positioned in the shaft or drift at one side of the track or roadway and which carries a suitable engine adapted-to operate the drums to effect the winding'o'r unwinding of the cable. v i 7 1n the accompanying drawings:

.;Fig. 5 is a detail elevation showing the transversely dlsposed longitudinally exten sible prop at the forward end ofv the beam. Fig. 6 is a detail elevation of the upper portion of the arch bar.

. As'illustrated in the accompanying drawings, a track 1 'is positioned upon the floor of the shaftor drift and a car2'is arranged to move along the track ina usual manner. The scooping apparatus comprises an arch bar 3 provided at its ends with adjustable spikes 4 adapted to be engaged with the floor of a shaft on drift-at the opposite sides of the track 1 whereby the intermediate portion of the arch bar 3 is disposed over the track and bridges the same- An Lbeam 5 is pivotally connected at one end with the upper intermediateportion of-the. arch bar 3 and carrles at its'free end a transversely disposed longitudinally extensible prop 6,

the ends of which may be engaged with the side walls ofthe' shaft ordrift. Apulley 7 is mounted upon the intermediate portion of the prop 6. The lower flangeof the I-beam. 5 is providedat intervals along its length withnotches 8. An arm 9is .connected with the lower flangeof the-I-beam 5 in the vicinity of the archbar 3 andcarrles at its lower enda pivoted hook 10..the purpose ofwhich will later appear.

A carriage 11 is mounted for movement along the I-beam 5 and is. provided with journaled wheels 12 adaptedto travel-upon the upper surfaces of the lower flangesof the Lbeam, the saidwheels being journaled upon the carriage at the inner surface'sof the sides thereof. A; pulley l3-is journaled upon the carriage 11 at a point below the I-beam. The prop 14, of usualfstructure is adapted to be positioned in an upright posture inthe'mine or drift at one side of the track 3 and an engine 15 is mounted upon the prop 14 Drums- 16 and 17.are journaled upon the prop 1 1: andvare operatively connected w th the englne whereby the said drums may be rotated by the englne when the same is in operation. A cable 18 is arranged with its opposite ends connected Withthe drums 16 and 1? and this able is adapted to be wound uponfirst one of these drums and then the other during operation of the apparatus, as will be later clearly understood. The cable '13 is trained over pulleys 19 mounted uponthe intermediate portion of the arch bar 3 and one run of r the cable 18 istrained over the pulley 13 mounted upon the carriage 1.1 and passes through the carriage 11. and is sewn-ed to the same at the point 20. From the point 21. on the carriage 11, the cable is extended and trained over the pulley 7 and is then extended back over one ot'the pulleys '19 and led to the drum 1?. q a

A block 21 is adapted to be received, in the carriage 11 between the sides thereof and the said block is provided with a journaled pulley 22'under which the cable 18 a passes. The block 21 is provided at its sides with vertically disposed cleats 23which are approximately wedge-shaped in side elevation. Stop members 24 are pivotally mounted upon the sides of the carriage 11 andare held toward the same bymeans of springs The free end portions of the blocks 24 pass through openings 26 provided in the sides of the carriage and. under the influence of thesprings the inner portions of the blocks may enter the notches 8 upon the I-beam 5 whereby the carriage may be stopped in its movement upon the I-beam and when the stops engage in the notches.

When the block 21 is in position between the side walls of the carriage 11, the outer surfaces of the cleats 23engage the inner surfaces of the stops and force them outwardly against the tension of the springs 25, Wherebythe inner portions ofthe stops are held beyondathe outer edges of the lowerfianges of the I-beam 5.

Levers 30 are fulcrumed at the sides of the carriage 11 and: are provided at their inner sides with blocks 31 which pass through the sides of the carriage 11 and which are adapted to extend under the lower ends of the cleats 23 when the block 21 is in position in thecarriage 11. Springs 32' are connected with the free end portionsof the levers 3() and with a cam 34 and are under tenslon with a tendencyto hold the blocks 31 under the lower ends of the cleats 23; The cam 3e is pivoted uponthe carriage 11 and its cam surface is in engagement with the free ends of the levers 30. The cam member 34 is provided with an arm 35 to which a cable 36 isattachedand the said cable 36 carries a handle grip 37. A bail 38 is pivotally connected with the lower portion of the block 2l and a scoop 38 is carried by the bail 38. The scoop 39 is provided at its rear end with an eye 41 with which may be engaged thehook 10 carried by the arm 9, V

(previously mentioned) The operation of the muck scooping apparatus is as follows :The car 1 is moved to a point on the track betweenthe arch bar 3 and the pileof muck which is to be removed from the stops or shaft. The engine 15 is then operated sothat the cable 18 is unwound from the drum16 and wound upon the drum 17, therefore the carriage 11 is moved along the I-beam 5 until the carria e and the scoop are above the pile of none I.

The operator then pulls upon the cable 36 7 whereby the cam member 34: is turned and the free ends of the levers 30 are swung held at a fixed position upon the I-beam.

a When the scoop 39 has been loweredin contact with the pile of muck, an operator uses the handles 40 and projects the scoop under the muck. The engine 15 is then opera tively connected with the'drum 16 whereby the cable 18 is wound upon. the drum 16. This willlli-ftthe block 21 and the loaded scoop 39 and when the lower ends of the cleats23 pass above the upper edges of the levers 30, the said levers are swung under the lower ends of the cleats whereby the block 21. is supported in thecarriage 11. At the same time, the outer surfaces of the cleats 23 comein contact with the inner surfaces of the stop members 2st and force the said stop members out of the notches 18 with which they have been engaged. Therefore, the carriage is released upon the I-beam 5 and as the cable 18 continues to be wound upon the drum 16 and unwound from the drum'17 the carriage 1.1 is moved toward the arch bar 3 and when the scoop 39 arrives in the vicinity of the arm 9, the hook 10 is engaged in theopening 41 and at the same time the operator pulls upon the cable 36 which disconnects the block from the carriage as hereinbefore described, and the cable 18 unwound'from the drum 16, thereby permitting' the forward portion of the scoop'to swing downwardly whereby the contents of the scoop may gravitate from the same'ancb fall intothe car 2; Thisop- .erationina'y be repeated until the car is loaded when itmayfbe removed from the shaft or drift along the roadway or track 1 a in the usual manner. a
