DITCHING-MACHINE.

Specification-of Letters Patent.

Patented Aug. 8, 1916.

Application filed February 10, 1915. Serial No. 7,348.

- a citizen of the United States, residing at Vincennes, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Ditching-Machines,

of which the following is a specification.

, This invention appertains to certain new and useful improvements in excavatorsor ditching machines, and in the construction of a machine made to accord with my invention there is provided a frame that issupported upon wheels, said frame carrying a motor as well as a capstan, of the drum and clutch type. The frame also carries at its forward portion a mast with which is associated a boom and a pivoted member, the boom being adapted to be swung to position for excavating and to one side of the frame to deposit the excavated material to one side of the ditch. The parts constituting my 111- vention are so organized that the main wheel supported frame is moved forward as the excavating or ditching proceeds, the scoop being filled by movement toward the wheeled frame, and when filled the scoop is raised and is swung to one side of the ditch where it is turned to discharge its contents.

The accompanying drawing shows a side elevation of my invention embodied in a preferred form.

The main frame of the ditching machine or excavator comprises-longitudinal beams 1, and transverse sill pieces 2 and 3, the rear sill 2 having attached thereto an axle 4 upon which is mounted the rear wheels 5, 5. The axle 4 and the sill 2 are preferably rigidly connected one to the other and the wheels 5 are of greater diameter than the front wheels 6 which are on an axle attached to a bolster, so that the front wheels may be turned under the beams 1. In practice the bolster and axle for the front wheels may be connected with suitable steering mechanism and the rear wheels 5 can be driven by an engine mounted on the main frame.

The longitudinal beams 1 are connectedby the transverse sill pieces 2 and 3 and by intermediate cross pieces 7, which carry the frame of a capstan or winch, having an engine and boiler, of a type manufactured by the Lidgerwood Manufacturing Company, and patented July 3, 1900, No. 652,798 and September 14,1909,No. 933,825.

The mast 8 comprises two upwardly converging beams the lower ends thereof being secured to the sill 2 and to the longitudinal beams 1, and from the upper end of the mast extend divergin braces the lower ends thereof being secure to the front ends of the beams 1. The two beams of the mast are connected at intervals by cross pieces or braces 9, 10, 11, 12 and at the top by a fixture 13 having an upward projecting pin 14 to receive a loop to which is attached a swinging stay-bar 15 that extends and is secured to the upper end of an arm 16. The upper cross pieces 9 and 10 of the mast maintain centrally disposed sheaves 17 and 18, guide rollers 19 and 20 being mountedupon suitable supports. The upper face of the sill 2 has secured thereto a turntable 22, having a rim with flanges, between which flanges is passed a rope that is suitably guided for engagement with a drum 60. The turntable is also provided with apertured lugs 26 which are fixedly attached to the turntable and to which the beam 27 is pivoted. The member 16 has guide pulleys 45 and 46 for a rope or flexible connection 44, that is used to exert a draft upon the scoopbeam 40 on both sides of its pivotal point of connection with the boom 27.

The boom 27 comprises two side pieces of metal, preferably I-bars which converge from the lugs 26 to which they are pivoted to their outer ends, where they are connected by a loop 30, and at intermediate points the side bars of the boom are connected by blocks or stays. To the connected ends of the I-bars there is attached a loop 30 which carries a sheave 33, over which is passed a rope 44, said rope extending from a loop attached to the beam to the roller 44. The

rope 44 which is attached to the scoop-beam,

nection with the beam 27. A flexible con nection 34 is used for dumping the scoop is attached tothe beam 27 at 35, and is passed about a sheave 36 attached to the scoop, and from thence over a sheave 36' carried by the boom 27 and then over a I guide roller, so that by drawing upon the are secured straps 42 which carry a sheave 43, about which passes a rope 44 which is used not only for dumping the scoop 34 such rope also being used for raising and lowering the boom. The lower end of the scoop-- beam 40 carries arms 47 which are pivoted at their lower ends to the sides of the scoop or dipper 38, and a bail 48 is also connected to the sides of the scoop and carries a sheave 49 with which engages a rope 50 attached to the boom and after engaging the sheave 49 extends over a guideroller 51 carried by the boom and from thence to a sheave 18 on the mast and thence to one, of the drums of the capstan or winch. When the boom is lowered the rope 50 is used to move the scoop or dipper forward to fill the same.

The ditching machine hereinbefore described is moved by power carried by the wheeled frame, and is advanced as the ditching proceeds, and the soil excavated may be placedeither on one or both sides of the ditch or can be deposited in carts or wagons located to one side of the ditch. The different drums of the capstan or winch are readily operated in the desired directions by shifting properlevers, and when the steam generated in the boiler is not used to operate the drums of the capstan o-r winch it may be used to drive the engine which moves the wheeled frame. The steering of the wheeled frame, and the moving of the same either backward or forward is accomplished in the usual manner.

In operation the wheeled frame is moved to the place where it is desired to dig a ditch, the boom is lowered and the scoop is positioned so that the teeth will engage with the surface of the ground. The scoop is moved forward by draft upon the rope 50, which with the other connections will cause the scoop to be moved in the segment of a circle and when filled the boom'may be raised and swung to one side and when in position for dumping the scoop is dumped by draft exerted upon the flexible connection 34.

In a ditching or excavating machine of the class described the scoop is connected'to a scoop beam which is pivoted to the boom, such boom being pivoted at one end to a turn table; in advance of the mast, and between the mast and the boom is a member which carries guide pulleys or sheaves over which the flexible connectlons pass to sheaves on the mast from which the flexible connections pass to drums on the frame of the carriage. The parts are so organized that to fill the scoop or bucket it is moved toward the carriage, the scoop-beam being pivoted tothe boom is held against upward movement, by the weight of said boom to which is added the weight of the scoop and the scoop-beam. The boom is mounted to be raised and lowered as the excavating proceeds, and is swung to one side to dump the earth alongside of the ditch, and after the ditch has beendug to the desired depth the carriage is moved forward for further excavation.

I claim 1. In a ditching machine, a wheel supported carriage, drums mounted on the carriage, actuating means for the drums, a mast provided with sheaves, a boom pivoted at one end to a turn table and associated with the carriage in such manner that the end of the boom farthest from its pivot may be moved both upward and sidewise, means for raising, lowering and laterally moving the boom, a scoop-beam pivoted to the boom, a pulley associated with the upper end of the scoop-beam, a pulley associated with the lower end of the scoop-beam, flexible connections for engagement -with the pulleys attached to the scoop -beam and with sheaves on the mast and a flexible connection that engages with a pulley attached to the rear portion of the scoop for turning the scoop upon the scoop-beam.

2. In a ditching machine, a wheel sup-.

ported carriage, a capstan mounted on the wheel supported carriage and provided with a plurality of drums, means for actuating the drums, a mast having attached thereto pulleys, a boom-associated with the wheel supported carriage to swing vertically and laterally, flexible connections for raising; lowering and swinging the boom, a scoopbeam pivoted to the boom and provided with i a pulley that is attached to the end thereof that extends above the'boom, a scoop'pivoted to the scoop-beam, means engaging with a pulley attached to the lower portion of the scoop-beam for moving the scoop toward the Wheel supported carriage, and a flexible connection which engages the boom, a pulley at the rear portion of the scoop and a pulley on the boom to provide Lneans for turning the scoop upon the scoopearn.

In testimony whereof I affix my signature Witnesses:

EUGENE W. JoHNsoN, JAS. H. BLACKWOOD.
