DIGGING AND VLOADING MACHINE.
SPECIFICATION forming part of Letters Patent No. 754,592, dated March 15, 1904..
Application filed January 30,1903. Serial No. 141,123. (No model.)
To (LU whom it may concern.-
Be it known that I, DANIEL MCDONALD, re-
"siding at Bruce Mines, in the district of Al-- can be manipulated by one operator.
In carrying out the invention I employ one or more buckets or scrapers connected to a carrier chain or belt revolubly mounted in a carrier-frame and driven by a suitablemotor. The carrier-frame is adjustably connected to the main frame, and the main frame is supported on a movable truck or platform and fitted with an adjusting-gear whereby its relative position to the movable truck or platform can be laterally altered from time to time as the work progresses without varyingthe lateral position of the movable truck or platform.-
In the drawings, Figure 1 is a side elevation of the complete apparatus, showing the construction and relative position of the various parts. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of the same. Fig. i is a-longitudinal section through the movable truck. Fig. 5 is an enlarged perspective view of a portion of the truck and table, showing the adjusting-gear for moving the table relatively to the truck I Like letters of reference refer to like parts throughout the specification and drawings.
Supported on the top of the movable truck or platform a is a swing-table b, pivotally connected thereto by a swing-bolt -c, from the center of which the swing-table oscillates during its lateral adjustment. J ournaled in bearings connected to the swing-table Z) is a wormshaft d, meshing with a curved rack 0, connected to the movable truck or platform a, the curvature of the rack being described from the center of the swing-bolt 0, and fitted to the worm-shaft d is a bevel-pinion f, meshing with a corresponding bevel-pinion g, fitted to a pinion-shaft it, journaled in bearings connected to the swing-table. The rotation of the pinion-shaft causes the swing-table to 0s cillate either to the right or to the left on a curve described from the center of the swingbolt to bring the buckets or scrapers at the loading end of the machine into engagement with the work without materially shifting the position of the delivery or unloading end of the same and without necessitating any change in the lateral position of the movable truck or platform.
Rigidly connected to the top of the swingtable are two sets of standards and it, respectively, braced by dross-stays Z, and contained between the standards j and is is a carrier-frame m, having near its front end gudgeons 0, journaled in the standards j,-so as to permit of the front end of the carrier-frame being lowered or raised as the rear end is respectively raised or lowered. Connected to the top of the standards j and to the rear end of the carrier-frame is a block and tackle Z, the rope m of which, after passing through the uppermost pulley-block, is wound on a drum '0, mounted on a swing-table b, and connected to the drum 0 is a ratchet-wheel p, with which engages a pawl q, pivoted to the operatinglever 1". The rotation of the drum 0 in the direction indicated by arrow winds the rope m to raise the loading end of the carrier-frame, and the rotation of the drum in the reverse direction unwinds the rope to lower it. J ournaled in the ends of the carrier-frame are drums s, around which passes the carrier-belt t, and journaled in the carrier-frame between the drums s are idlers u to support the loaded buckets or scrapers as they pass from the loading to the unloading end of the frame. Journaled in the carrier-frame contiguous to the drum 8, at the front end thereof, is a shaft 0, upon which are mounted two sprocketwheels to and w, and mounted on the mandrel of the drum 8 is the sprocket-wheel w, around which and the sprocket-wheel a passes a sprocket-chain w" to transmit motion from the shaft o to the drum 8 to drive the carrierbelt 6. Passing around the sprocket-wheel m and around a sprocket-wheel y, mounted on a driving-shaft 2, is a sprocket-chain a, and forming part of the driving-shaft 2 is a crank Z, to which is connected the piston-rod c of the engine or motor d, by means of which the shaft 2 is driven.
The axles e for the movable truck or platform are journaled in suitable boxings connected to the under side of the top of the movable truck or platform, and mounted upon the axles e are the track-wheels Mounted upon the axles e, between the track-wheels g, are sprocket-wheels it, around which passes a sprocket-chain Z, and mounted on one of the axles e is a ratchet-wheel j, with which engages a pawl is, pivoted to a lever Z, fulcrumed on the axle on the outer side of the ratchet-wheel j for the purpose of rotating it. By means of the lever Z and ratchet-wheel j the movable truck or platform can be shifted along the track-rails m.
Connected to the loading end of the swingtable is an inclined guard 0", with which engage the buckets as they return from the unloading to the loading end of the carrier-frame, the purpose of the guard being to prevent the buckets or scrapers coming into contact with the swing-table or the machinery mounted thereon.
Instead of connecting the block and tackle to the standards it I may, if I so desire, connect it to the brace Z, uniting the upper ends of the standards 7:, this brace Zbeing substantially arc-shaped to give plenty of clearness to the buckets or scrapers as they pass from the loading to the unloading end of the carrier-frame when the carrier-frame is in its most elevated position.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a digging and loading machine the combination of a movable truck or platform, a swing-table mounted thereon, a worm-shaft for'the swing-table, a rack connected to the movable truck or platform meshing with the worm shaft, a pinion shaft, intermeshing bevel-pinions mounted on the pinion-shaft, worm-shafts, a main frame supported by the swing-table, a carrier-frame journaled at one end to the main frame, an adjustable gear for raising and lowering the other end of the car'- rier-frame, drums mounted in the carrierframe, a carrier-belt passing around the drums, buckets connected to the carrier belt, a sprocket-wheel for driving the carrier-belt, a motor and means for transmitting motion from the motor to the sprocket-wheel, substantially as specified.
2. In a digging andloading machine the combination of a movable truck or platform, a swing-table mounted thereon, a worm-shaft for the swing-table, a rack connected to the movable truck or platform meshing with the worm shaft, a pinion-shaft, intermeshing bevel-pinions mounted on-the pinion and worm shafts, a main frame supported by the swingtable, a carrier-frame journaled at one end to the main frame, an adjustable gear for raising and lowering the other end of the carrierframe, drums mounted in the carrier-frame,
a carrier-belt passing around the drums, buckets connected to the carrier-belt, a sprocket- Wheel for driving the carrier-belt, a motor,
means for transmitting motion from the motor to the sprocket wheel, and means for shifting the position of the movable truck or platform, substantially as specified.
