LOADING- MACHINE.

Application filed July 31, 1925 Serial No. '$7,310.

This invention relates to loading machines being raised and lowered. For this purpose and has for an object the provision of a machine which is especially adapted for use in excavating.

An object of the present invention is the provision of a loading machine by means of which plowed or loose dirt may be picked up, anddeposited in wagons or trucks, the construction being such that the machine will operate in narrow streets or roadways and close to a curbing or the like.

Another object of the invention is the provision of a machine of the above character which will do its own plowing or excavating of comparatively loose dirt, the'plow or shovel of the machine being mounted so as to dig into the dirt but will be permitted to yield in the event of contact with a rock or other hard object.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of an excavating machine constructed in accordance with the invention, one of the deflector plates being partly broken away.

Figure 2 is a top plan view.

Figure 3 is a fragmentary transverse sectional view.

Figure 4 is a detail side view of the mechanism shown in Figure 3.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates the frame of the machine which is supported upon wheels 11 and which in turn supports the loading mechanism.

This loading mechanism consists primarily in a plow or shovel 12 which includes a cylinder having aplurality of trough-like scoops 13 extending from its periphery. These scoops or shovels 13 extend axially of the cylinder 12 and are designed to rotate in a direction opposite the travel of the machine.

The cylinder is mounted upon a shaft 14 which operates in bearing arms 15 at each end thereof.

The shovel is mounted centrally and to one side of the machine and the arms 15 are capable of limited vertical movementwithin the frame so as to permit of the shovel the'arms 15 are provided with arcuate'slots 16 through which extend pins 17 carried'by the frame.

In order to adjust the arms to regulate the vertical position of the shovel, the arms which are of arcuate shape are provided along one edge with a rack 18 which is engaged by a pinion 19. This pinion is mount ed, upon a short shaft 20 which is rotatable in suitable bearings extending from the frame and which is connected to a vertically disposed shaft 21 by means of beveled gears 22 The shaft21 is provided with a hand wheel 23 by means ofwhich it may be conveniently rotated.

By rotating the shaft 21, the arms 15 may be raised or lowered so as to regulate the position of the shovel 12 and permitit to work either shallow or deep, or to raise the shovel when the machine is being moved from one position to another.

Extending transversely of the frame 10 is a shaft 24 and pivotally mounted upon this shaft at each end of the shovel 12 is a deflector plate 25, the lower edge of which is adapted to drag over. the surface of the ground. These plates 25 act to confine the loose dirt so that it may be readily picked up by the shovel.

The shovel is rotated by an engine or motor 26 which is mounted on the frame 10 and which is geared to a shaft 27 as shown in Figure 1 of the drawings. This shaft 27 is operatively connected to the shaft 21 by achain and sprocket drive 28, while the shaft 24: is operatively connected to the shaft 14 by a chain and sprocket drive 29.

Located adjacent the shovel 12 and arranged so as to receive dirt therefrom is an elevator which includes an upper shaft 30 and a lower shaft 31, the former being mounted in bearing standards 32 and the latter in bearing arms 33 which are secured to the frame 10. This elevator includes a belt 34 and spaced buckets 35, the latter receiving the dirt from the shovel 12 and carrying it upward. The elevator is driven by means of a belt 36 from the shaft 27 to the shaft 30.

The elevator is designed to deposit the dirt upon an endless conveyor or apron 87, the latter operating over rollers mounted upon shafts 38 and 39. The shaft 38 is mounted in the standards 32, while the shaft 39 is mounted in bearing arms 4C0 which extend upper endof the elevator, a rotary shovel located-adjacents the lower end of the elevator, said shovel comprising a cylinder and axially extendingtrough-shaped scoops carried thereby, vertically movable pivotally mounted deflector plates at opposite ends of and. movable independently of the shovel, means for operating the shovel, elevator and conveyor, means vvhereby the shovel may be vertically adjusted and yieldahle means for holding the shovel against upward movement.

2. A loading machine embodying a wheel supported frame, standards extending upward from each side of the frame adjacent the rear thereof, bearing arms extending downward from each side of the frame in advance of the standards, an elevator having its upper end mounted at the top of the standards and its lower end mounted in the bearing arms, standards extending upwardly from the opposite sides of the frame at the rear end of the latter, a conveyor having its rear end mounted in the last mentioned standards and its forward end mounted in the first mentioned standards below the top of the elevator, a rotary shovel located in advance of the elevator and means to operate the shovel, conveyor and elevator.

In testimony whereof I aflix mysignature.
