EXCAVATING MACHINE.

Application filed May 5,

quarries, etc, although it is susceptible of use in other capacities, the invention pro- V1Cl111 a machlne which 18 simple 1n constructlon and possessing maximum strength i and rigidity to withstand the strain and rough usage to which it is subjected.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a side elevation of the machine constructed in accordance with my invention.

Figure 2 is a top plan view.

Figure 3 is a rear end elevation.

Figure 4 is a horizontal sectional view taken on the line 44 of Figure 1.

The machine forming the subject matter of my invention comprises a frame indicated generally at A, the frame being made up of angle iron, and being substantially of tri angular formation. The frame is reinforced by vertically disposed braces B rising from the frame at a point adjacent the rear axle. The frame is mounted on front and rear wheels 12 and 13 respectively, the axles for which are indicated at 14:. A motor of any suitable character is indicated generally at B, and is mounted upon the frame in the position shown. The rear wheels 13 are of the tractor type and are connected with the motor B by any suitable driving means, I preferably make use of a chain drive, the driving mechanism including a clutch mechanism, so that the machine may be moved in a forward or rearward direction at the will of the operator.

Mounted at each corner of the frame in triangular relation, are sprocket wheels there as found desirable.

1920. Serial No. 379,127.

' being preferably three of these wheels 15 fixed upon the shaft 16, three of such wheels indicated at 17 fixed upon the shaft 18 and three of such wheels indicated at 19 fixed upon the shaft 20. Endless chains indicated at 21, three in number, are trained over the respective gear'wheels, the chains carrying the buckets as shown. The upper part of the frame has j ournalled thereon spaced rollers 22 over which the upper runs of the.-

endless chains travel. Belting .of any suitable character is indicated at 23, and shown as covering the chains 21, at points between the bucket, the belting serving to prevent any of the contents of the bucket from falling through the chain and frame or from coming in contact withany of the working parts of the machine. I also provide a guard 25 for the front sprocket wheels 15.

The buckets are indicated at 26 and are suitably spaced about the chain and any number of these buckets may be employed The buckets are preferably of the configuration shown, and are reinforced with strap iron which extends about the. bucket at the top as indicated at 27. The buckets are preferably of a width to extend across all three chains, and are connected to the latter at points adjacent the tops and bottoms of the buckets. Projecting from both the top and bottom of each bucket, beyond the side which reposes upon.

th chain 21, are apertured ears or lugs'indicated at 28 through which and the alined links of the chain are passed rods 29. The lugs 28 form an integralpartof each bucket or they may be secured thereto in any suitable manner. It will be noted that the front sprocket wheels 15 are disposed an,

rear end thereof and is inclined upwardly as indicated at 31, this part of the machine serving to support a chute 32 which is secured to the frame proper as at 33. The

chute is arranged beneath the sprocket wheels 17, projecting rearwardly beyond the latter to receive the contents of the bucket when they assume dumping positions, or in other words as the buckets pass around the sprockets 17. Thematerial from the chute 32 is directed onto a conveyor 35, so that the material handled by the buckets can be loaded at a point remote from the machine proper.

While it is believed that from the "foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself in this connection and that such changes may be resorted to when desired as fall Within the scope of what is claimed.

Having: thus described my invention What I claim as new is An excavating machine comprising amovable support having front and rear axles, Wheels mounted on said axles, a sub stantially triangular shaped frame having one side horizontally mounted on the said axles with one end thereof extending beyond the front wheels and a second side extending upwardly and outwardly beyond the rear Wheels vertical supports connecting the third side with the two said sides, a plurality of sprocket Wheels mounted at each corner of the frame, endless chains trained around said sprocket Wheels, spaced buckets carried by'said chains, an endless belt mounted over the chains beneath the buckets, and means for rotating the chains.

In testimony whereof I atliX my signature FREDERIC J. DUSSAULT,
