Application-flied April as, 1910. Serial No. 557,468;

To all whomit may concern:

Be it known that we, JOHN Gronen LEY- United States of America, the former residing at the city and county of Denver and State of- Colorado, and the latter residing at Golden, county of Jefferson, State of Colorado, have invented a new and useful Oscillating-Shovel Muck-Remover for Tunnels, of which the following is a Specification.

Our invention relates to a new and improved oscillating shovel mucker for removing blasted, broken-down, or crushed material such as ore, rock, gravel, and dirt, which --is termed muck, from the breasts of tunnels; and the objects of my invention are: first, to provide a machine having an oscillating shovel point for .removingand "the muck and works under it; and third, to

. rovide a muck removing machine that can e arranged in tunnels to, be forced directly under the body of muck. material at the breasts of tunnels, and thatjwill load the muck automatically onto cars, or discharge it from the end of the conveyer, and as it. is drawn under the body of the muck material.

We attain these objects by the mechanism. illustrated in the accompanying drawings,

in which:-

Figure 1, is a plan view of the supporting frame of our oscillating shovel muck removing machine, a fragment onlyofthe inclined conveyer frame, which is pivotally connected to the forward. end of the truck, being shown. And Fig. 2, is a vertical longitudinal section of our improved muck shoveling machine.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings,".the frame of tlieinucker consists of the side beams 1 and thcross pieces 2; and these beams are preferably made of structural iron. The frame is preferably mounted on car wheels 3, whichare rotatably mounted on axles 1, which are fully shown.

secured to the underside of the front and rear ends-of. the frame. To the front end ofthe machine are secured 'two capstans 5 and beams 1. Upon the center of the shaft 7, is secured a-gear 9. Parallel to the shaft 7, is mounted in suitable boxes 10-a-sha'ft 11,

and upon the central portion of this shaft 11, is secured a pinion 12, which meshes with the gear 9. At the side of the pinion 12, is secured a'gear 13, which meshes with a pin-- ion 14, on a shaft 15, which is revolubly journaled in boxes 16, that are secured to the frame of the machine in any suitable manner. .To the shaft 15 is also secured a gear 17, which meshes with a pinion 18, that is secured to shaft 19. A bevel gear 20 is also secured to the shaft 19, which meshes with a bevel pinion 21, secured upon a shaft 22,.that

is revolubly mounted in boxes 23, that are secured to a platform 24', which is attached to the side beams of the frame. This shaft is connectedin any suitable manner to any suitable engine or motor, but wepreferably use, however, a compact rotary reversible Dake engine 25, and the shaft 22, is connectf. ed directly to the center disk of the engine, This engine is mounted upon and is securedsuitable manner to the frame of the 7 in an mach1ne.- The engine 25 thus drives the train of gears above enumerated and rotates the capstans 5 and 6. Y

Uponthe shaft 15 is loosely mounted a sprocket wheel 15*, which is connected by a chain 15 with a sprocket wheel 15, rigidly mounted onthe forward supporting axle 4 of the wheel frame. The sprocket 15" has a clutch which is normally engagled by a clutch 15 on the shaft 15, sothat t e power from the shaft 15 will be transmitted to the sprocket 15, by means of the chain 15 to move the machine either forward or backward; but when it is desired to raise or lower the inclined conveyer frame, the clutch 15 is thrown out of engagement with the sprocket wheel 15', as will hereinafter be The clutch, is operated by means of a lever 15 The capstans each comprise a drum 25 and two flanged-portions 25 and 25". One flange 25 of each drum, is made wide enough to contain a circumferential row of holes 25 that are adapted to receive one end of a lever, by which they may be turned by hand when necessary.

To the drums 25*, we secure two ropes 26 and 27, the free ends of which are secured to.

hooks 28, which engage the forward edge of a foundation plate 35, which comprises two heavy plates of iron that are detachably bolted together at their meeting ends by bolts 29. These plates form a smooth surface for the lip of the shovel to slide on, as

it is forced forward under the ore or rock or other material knocked down at the breast of the tunnel. As our machine is adapted to be used at the breasts of tunnels for removing and depositing in cars,

the rock, ore, dirt, or muck that is thrown down in blasting, we have illustrated it in plan and elevation in operativeposition at the breast of a tunnel.

To the forward ends of the side beams 1,

is secured a supporting frame, which consists of side beams 36, which are connected by a bottom plate 37 and a bolt 38. This bolt extends through the front ends of the beams 36, and upon it is pivotally mounted the improved muck shovel, which cons sts of a wedge shaped forging 39, which forms a shoveling lip, and rearwardly extending lever arms 39. This lip and the arms 39 of the muck shovel and the beams 36, are covered by a heavy sheet steel plate 40, for a portion of their lengths, and the sides of this plate are sloped upward and inward from a point adjacent to the edge of the lip of the muck shovel, so as to form a trough that will guide the rock, ore, dirt,

a chain with a sprocket wheel 39, on a Sleeve X loosely mounted on the drum shaft 7 The sleeve X is also provided with a sprocket .wheel 39*, which is connected by a 1 chain with a sprocketv wheel 39, on a shaft 39 mounted in bearings 39 on the side beams 1. The shaft 39 also carriesa sprocket wheel 39, which is connected by achain with a sprocket wheel 39, 011 the shaft 39,of an engine 39 similar to the engine 25. Thus, as the shaft 39 with the disks 39 are turned by the engine, through the medium of' the chains and sprocket wheels above mentioned, the pitman arms 39 im art an oscillating motion to the muck s ovel, which not only enables it to work'under the muck, butthe muck is thereby loosened or agitated so that it falls upon the plate or shield 40, whence it is delivered upon an endless conveyer, which we will now proceed to describe.

On the bolt 38 we pivotally mount one end of an endless belt frame 42, which consists of side pieces 43. and cross pieces 44. This endless belt frame extends rearward from the bolt 38, over and beyond the wheeled frame of the machine, and its rear end is supported and arranged to be raised and lowered over the wheeled frame to stand at any desired angle to convey the r ck, ore, dirt, or muck to its upper end, and dis charge it directly into cars or if desired into a suitable supplementary conveyer that will convey and discharge it into cars. In the belt conveyer frame adjacent to its pivotal bolt 38, and under the shovel plate, we rot-atably mount a roller 44*, on'a shaft 45, the ends of which are rotatably supported in a steel or iron casting or a forging 46,

which is secured to the side pieces 43 of the frame of the belt conveyer, and through the ends of which the pivotal bolt 38 passes, and along the, center of the length of the belt conveyer frame at suitabledistances apart -to support abelt, we mount a plurality of rollers 47, in boxes 48, which are attached to the cross pieces 44 of the frame, and on each side of each of these central rollers, we rotatably mount an inclined roller 50, which rollers are positioned at an upward angle from adjacent to the opposite ends of each of the center rollers to the side beams of the belt conveyer frame, where their outer ends are journaled in suitable boxes 51, which are securedto the side beams of the frame. The inner ends of these inclined rollers are also journaled in boxes 52, which are secured to the cross pieces 44. Upon the tops of the boxes 51, are secured strips 53,which support the side edges of the belt, between the rollers 50. These strips are connected at their forward endsby an integral plate 53*, which is adapted to lie beneath the connear the ends of these strips, which guide the belt over a drum 55, which is mounted on a shaft 56, that is journaled in suitable boxes that are slidably mounted on the side rails at the outer end of the belt conveyer vframe, and a suitable belt tightener 57,

may be employed for maintaining the required tension upon the belt. On the rollers 55 50, 47 and 44, We place a suitable belt, which in running over the inclined rollers forms a trough-shaped conveyer, that holds the rock, ore, dirt, or muck in itscenter without spilling it over its sides. The drum shaft 56 is provided at one end with a sprocket wheel 58, which connects by a chain 59 with a sprocket wheel 60, on a shaft 61, mounted in bearings 62, secured upon the under side of the conveyor frame adjacent to its rear end. The shaft 61 also carries a sprocket wheel '63, which is'connected by a chain 6 1, with a sprocket wheel -65, on the shaft 39 of the engine 39 of the car, the movable tubes havingthreaded rods 81 provided with bevel gears 82 at their lower ends, which mesh with bevel pinions 83 on the opposite ends of a shaft 84, which is driven by a chain 84c from the shaft 19, a clutch 85 being employed to throw the shaft 84 out of connection with the shaft 19, when the machine is in operation, and for connecting the shafts when it is desired to raise or lower the conveyer. We have not, however,

more fully described the mechanism for raising and lowering the conveyer, as we may employ any other suitable mechanism for accomplishing the same result, and a detailed description of this and otherfeatures of our invention is given in our pending application filed April 19, 1910, Serial No. 556,327. A

Supportmg arms 86 are pivotally secured to the car, the opposite ends of which are arranged to extend under the opposite side rails of the inclined conveyer when it is raised to its highest position, when its weight rests on these supporting arms.

The operation of the improved'mucker is as follows: We preferably use compressed air, as the motive .actuating fluid, and the engines on the mucker are operatively connected to a suitable supply of it.? The breast of rock is drilled with a sufiicient number of holes to blast its entire surface, and they are charged ready to be fired, but before a charge is fired, the floor plates 35 are laid down and the hooks at the ends of the ropes are hooked to the edge of the forward plate, while the mucker is run back a safe distance. The breast is then fired, and the ore and rock fall onto the floor plates on the ropes. The mucker is thenrun up on the plates by starting the engine 25, which at the same time winds up the rope, and forces the ram or shovel under the ore or rock. The inclined conveyor is then elevated to the desired angle by throwing in the clutch 85 that connects the shaft 19, with the shaft 84;, by means of chain 84*. The shovel of the mucker is then forcibly drawn under the fallen ore or rock by the engine, which through the medium of the train of gears causesthe shaft to rotate the capstans, which winds the rope slowly: and draws the shovel of the mucker under the ore or rock, while at the same time the shovel is given an oscillating motion by means of the pitman arms 39 which connect with the lever 39 of the said shovel, the pitman arms being operated by the disks 39 on shaft 39 which shaft is connected by sprocket wheels f'and chains with the shafts 39 of the engine 39*, the oscillating motion of the shovel causing the muck'to be loosened sothat it falls upon the, plate 10, which guides it onto the inclined conveyer, which is driven by the engine 39 The inclined conveyer discharges, the ore and rock upon a supplemental conveyer or directly into a car. Themucker can be thus drawn forward under the ore or rock by the ropes until the shovel reaches the breast of the. tunnel and all or the greater portion of the ore or rock will be automatically shoveled up and loaded into cars, while the small amount remaining at the sides of the tunnel can be shoveled onto the endless inclined belt by a man on each side of the mucker. l/Vhen desired, a lever can be inserted in either one of the capstans and they can be turned independently to even up the ropes 26 and 27, so that they will be of equal length, thus causing the pull to come in direct line with working a much longer time.

While we have illustrated and describedthe preferred construction and arrangement of our mucker, we do not wish to be limited tothe construction shown and described, as many changes-might be made without departing from the spirit of the invention, which contemplates any arrangement of a carriage and oscillating shovel that can be drawn under or forced into a body of blasted ore orrock in a tunnel, and that is provided with an endless conveyer belt that is arranged to elevate and discharge it into cars.
