Application filed February 25, 1908. Serial No. 417,663.

T all whom it may concern: 1

Be it known that I, JosEPH ORGAN, a citii zen of the United States of America, residing l at Metcalf, in the county of Graham and useful Improvements in Excavating-Mal chines, of which the following is a specification. i

This invention relates to excavating maj chines,and one of the principal objects of the same is to provide means for thoroughly, loosening the soil and for carrying it up by means 0 1a series of cups to an endless apron upon which the material is discharged and by means of which the material is carried backward and deposited upon an adjustable platform which may be inclined backwardly or laterally to deposit the material at the back or side of the machine.

Another object of the invention is to provide a steel drum armed with alternately arranged steel drag teeth for loosening the earth and cups orbuckets for scooping up the earth and carrying it back to an endless apron for discharge to the rear of the machine.

Still another object of the invention is to provide means for raising and lowering the steel drum. I

These and other objects may be attained by means of the construction illustrated in the accompanyin drawings, in which,

Figure 1 is a si e elevation of an excavating machine made in accordance with my invention. Fig. 2 is a plan view and partial section .of the same. 1* ig. 3 is a transverse vertical section of the same. Fig. 4 is a detail view of the endless carrier. Fig. 5 is an enlarged detail section of a portionof the steel drum.

Referring to the drawings for a more specific description of my invention, the numeral l designates a frame to which the traction wheels 2 are journaled by means of the boxes 3; The steel drum 4 is hollow-and is provided at its ends with spokes. 5 and central hubs 6. Extending through the hubs 6 is a shaft 7, the ends of said shaft being jourvers 8 whio are pivoted at 9 to brac ets 10 secured to the side bars of the frame. To support the wheel in its lowermost position a bracket 11, one at each end of the drum, is provided with an enlarged upper end 12 which assists in supporting the drum in its lowermost position, said bracket being se- 1 with gear Wheels 40 on' theshaft 23.

cured by bolts 13 to the frame of the machine. Secured to the periphery of the drum 4 are the drag teeth 14 provided with squared j shanks 15 which extend through apertures in Territory OfAllZOIliL, have invented new and j the drum-and are screw-threaded and fitted with nuts 16 for holding them firmly in place. Arranged alternately with the drag teeth are cups or buckets 17, said buckets extending entirely across the drum and at the ends be ing provided with flanges 18 which are secured by rivets tothe end flanges 20 of the drum.

On the ends of the drum are formed gear teeth 21 which are engaged by gear wheels 22 mounted upon shafts 23 journaled in boxes 24 secured to standards 25 rising from the frame of the machine, A spring cable 26 connected to a bracket 27 one upon each end of the drum 4, passes up over a pulley 28 and is wound upon a drum 29 journaled in boxes 30 secured to uprights 31 rising from the frame of the machine. Hand cranks 32 are provided for rotating the drums '29 to raise the drum 4 to regulate the depth of out and to hold the drum elevated When the machine is moved from place to lace.

An endless carrier ma e up of pivoted links 33 carrying angle iron flights or risers 34 and intermediate site ends with crown gears 3 6 w ich mesh with gear wheels 37 on the stub shafts 23 journaled in the standards 25. The endless carrier is inclined upwardly, and at its upper end the roller is provided with a shaft 38 which extends outwardly from the roller and is provided with crown gears 39 which m lekslh e shaft 38 is journaledin boxes 41 secured to standards 42 rising from the frame. standards 25, 31 and 42 are connected by longitudinal bars or'braces 43. On the ends of the shaft 38 belt pulleys 44 are secured, and one of these belt pulleys is used to transmit: motion to the arts of the excavator, while the other may he used as a fly wheel.

In order that the weight of the materials carried by, the drum and dumped upon the carrier may not depress said carrier and render it ino erative, a platform 45 is placed underneath the carrier-at the point where the materials are discharged thereon, as shown more particularly in Fig. 1. At the rear end of the machine and supported upon standards 46 and a cross bar 47 IS a discharge ates. 35 is mounted on rollers, the lower rol er being provided u on oppo- The' platform 48 provided with curved brackets 49 which permit the platform to be adjusted at various inclinations by means of a binding screw 50.

The operation of my invention may be briefly described as .follows: The machine is mounted upon tracks, and the drum is designed to excavate to a depth equal to the sleepers for the tracks, and when the drum is raised and the tracks are laid the machine may be moved from place to place or advanced as the work advances. The drag teeth loosen up the earth, and the buckets scoop it up and carry it back to the endless carrier upon which it is deposited and discharged upon the platform 48 from which it is slid 03 at the back or at the side of the machine, depending upon the adjustment of said platform.

From the foregoing it will be obvious that anexcavator made in accordance with my invention is of comparatively simple construction, and will cut its own way through a pile of earth or other materials and will deposit the materials either at the side or back u on wagons or upon the'banks at the sides of the excavation.

. Having thus described the invention, what is claimed as new, is

1. An excavating machine comprising a hollow steel drum, a series of steel drag teeth secured to the periphery of said drum, a series of buckets secured to said drum, said dra teeth and buckets being arranged alt-ernate y, means for raising and lowering said drum, an endless carrier, and a tilting platform for discharging the material.

2. In an excavating machine, a hollow steel drum, steel drag teeth provided with squared shanks and secured in openings in said drum, said drag teeth being secured at equal distances apart across said drum, and a series of buckets secured to said drum, said drag teeth and buckets being alternately arranged, said drum having end flanges to which the buckets are secured.

3. In an excavating machine, the combination of a steel drum armed with drag teeth and buckets alternately arranged on the periphery thereof, means for rotating said drum, means for raising and lowering said drum, an endless carrier, and an adjustable latform.

4. in an excavating machine, a hollow steel drumarmed with drag teeth and buckets, gear teeth on the ends of said drum, shafts mounted in the frame, gear wheels mounted on the shaft for engaging the teeth on the drum for rotating the same, an endless carrier made up of angle iron flights and pivoted links, means for rotating said carrier, and an adjustable platform for discharging the material.

In testimony whereof I affix my signature in presence of two witnesses.
