JOSEPH SAMPSON, OF SIOUX FALLS, SOUTH DAKOTA.

EXCAVATOR AND LOADER.

SPECIFICATION forming part of Letters Patent No. 779,239, dated January 3, 1905.

Application filed April 21, 1904. Serial No. 204,271.

To ctZZ whom it may concern.-

Be it known that I, J OSEPH SAMPSON, a citizen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Excavators and Loaders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a dirt excavator and loader, and has for its object to provide an apparatus of this kind which may be mounted upon an ordinary vehicle-body and employedto excavate the earth while the vehicle is in motion and discharge the same into a dirtwagon driven alongside the excavator and loader.

In the accompanying drawings, Figure 1 is a side elevation of an excavator and loader embodying my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical longitudinal section. Fig. 4: is a cross-section.

Referring to the drawings, 1 represents the body of a vehicle of any construction suitable for the purpose. Mounted upon this body is a frame or superstructure 2, to which is pivotally connected at 3 the upper end of an inclined excavator-frame 4, carrying at its upper and lower ends shafts 5 and 6, around which passes the endless excavator-belt 7, provided with the scoops or shovels 8. The ex cavator-frame extends downward through an opening in the bottom of the body 1 to a point in close proximity to the ground-surface, so that when the excavator-belt 7 is in motion the shovels 8 will scoop up the earth and convey the same to the upper end of the excavator at a suitable elevation above the top of the body 1.

On the upper shaft 5 of the excavator is a sprocket-wheel 9, which receives motion from a double sprocket-wheel 10, mounted upon the body 1, through the medium of a connectingchain 11, which engages one of the sprocketsurfaces of said wheel 10. The other sprocketsurface of the wheel 10 is engaged by the upper stretch of a traveling chain 12, the lower stretch 13 of which is adapted to engage and receive motion from a sprocket-wheel let, fixed to, one of the rear wheels of the vehicle. Between its upper and lower stretches the chain 12 is guided at points in front and rear of the plane of the wheel 10 by idlers 15 and 16, the latter being mounted on a suitable adjusting device 17, whereby it may be raised to lift the lower lead 13 of the chain 12 out of engagement with the sprocket-wheel 14, and thus arrest the motion of the gearing and stop the excavator.

To the adjusting device 17 is attached one end of a chain 18, which passes over one or more guide wheels or pulleys 19 to the front of the body 1, where it is connected to the operating-lever 20, disposed in proximity to the drivers seat to enable the driver to conveniently throw the chain 12 into and out of gear.

The excavator is adapted to be lowered and raised for the purpose of throwing the same into and out of operation and to this end is connected at its lower end to a chain or analogous connection 21, passing over guide pulleys or wheels 22 and 23, located, respectively, on the front axle and body of the vehicle and connected at its forward end to a lever 24, disposed alongside of the lever 20, whereby the driver may conveniently adjust said excavator to throw the same into and out of operation, as will be readily understood.

Suitable pawls and racks or other locks may be provided to enable the levers and 24 to be held in adjusted positions. On the upper shaft 5 of the excavator alongside the sprocket 9 a miter gear-wheel 25 is mounted and engages a corresponding gear 26, which is connected, by means of an endless sprocket-chain and sprocket-wheels or other suitable devices, to one shaft of an endless conveyer 27, located within a chute 28, communicating at its inner end with the upper end of the excavator 7 and adapted to receive the excavated earth from the buckets 8. The chute 28 is arranged so as to project laterally beyond the box or bed 1, so as to discharge the earth taken up beyond the same and into a dirt-wagon driven alongside the excavator.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be readily understood.

It will be seen that it provides an excavating apparatus which may be readily mounted upon an ordinary vehicle-body and which may be cheaply operated, as it may be readilycontrolled by the driver of the vehicle and receives motion from the running-gear of the vehicle.

By the construction and arrangement of parts shown the device is easily operated and may be readily worked by a single team.

. Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an excavator and loader of the character described, the combination with a vehiclebody and its running-gear, of a sprocket- Wheel upon one of the elements of the running-gear, an excavator mounted upon the vehicle-body and comprising upper and lower shafts, an endless conveyer mounted on said shafts, a sprocket-Wheel on the upper shaft, a double sprocket-gear disposed below the same, a chain connecting the sprocket-wheel on said upper shaft with one of the sprocket elements of the double sprocketgear, a traveling chain running over the other sprocket element of the double sprocket-gear, and having a portion moving in contact With the sprocket-wheel on the running-gear of the vehicle, a delivery device actuated from the upper shaft of the excavator, and means for moving the running chain into and out of engagement with the sprocket-wheel on the running-gear, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH SAMPSON.
