DITCHING-MACHINE.

Specification of Letters Patent.

Application filed May 9, 1912.

atented June 2d, 1913.

Serial No. 696,126.

To all whom 2.25 may concern.'

Be it kno-wn that we, HARRY 1V. LUTZ and IVILLIAM HU'ror-nsox, citizens of the United States, residing at Antioch` in the county of Contra Costa, State of California, have invented certain new and useful Improvements in Ditching-Machines; and we do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in excavators and particularly7 to that class known as ditching machines the object of the invention being to produce a ditching machine having an improved excavating or digging point which will be easily adjustable for the different depths of ditches, there being in operation with such digging point an adjustable pair of disks adapted to ride ahead of the digging point to cut. the sides of the ditches. XVe further provide an adjustable conveyer, such conveyer and such disks having a raising and lowering means by means of which such conveyor, disks and digging point may be raised or lowered in one simultaneous movement, such digging point having a further independent adjusting means whereby its angle of operation may be changed according to the depth of the ditch.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly7 effective for the purposes for which it is designed.

These objects, we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of the complete device. Fig. 2 is a top plan view of the same. Fig. 3 is a sectional view of the digging point. Fig. 4 is a fragmentary view, showing the wheel structure and means for connecting the frame therewith.

Referring now more particularly to the characters o-f reference on the drawings, we first provide two main side beams 1 spaced apart and provided with a front cross beam -rear ends of said beams 1 as at 5a are blocks 5 secured to beams 6, which beams G project at an incline and are journaled at their rear ends upon an axle 7 carrying supporting' wheels 8. Such beams 6 are provided with projecting metal bars 9 provided with side boards 10. Pivotally' mounted on the members 9 on a pin as at 11 is an inclosed shoe 12 having a projecting arm 13 connected with the rear end of which are arms 14 provided with a plurality of holes 15 bolt-ed thro-ugh which holes may be a lever 16 having an operating handle 17 provided with a release rod and handle 20 having the usual form of release dog mechanism 21 engageable in a rack 22 secured to o-ne of the beams G. In the frame 12 is a digging point comprising a plat-form 23 bolted to the sides of the member 12 as shown in Fig. 3. Disposed between the sides of the member 12 and around the pin 11 just to the rear of the platform 23 is a pulley 25 movable over which is a co-nveyer 26 which moves between the members 9 and 10 and around a large pulley 27 disposed on an axle 28 journaled in the rear ends of the members G, such conveyer being an ordinary belt conveyer provided wit-h projecting iron flanges 29, such ccnveyer being adapted to discharge upon a side chute 30 at the rear end of the beams 6. 0n the shaft 28 is a gear wheel 31 which drives said shaft 28 and incidentally the conveyer 26 which gear wheel 31 is in turn driven by a gear wheel 32 secured on the axle 7 which is driven by means of the movement of the wheels 8 which are connected to said axle 7 by means of a pawl and ratchet structure 7 a of the usual type to permit the easy turning of corners.

The numeral 33 designates a shaft journaled in members 34 secured on the beams 1 and being adapted to engage a worm gear 35 having an operating handle 37 disposed. within reach of theoperators seat 38 and in this connection it is also stated that the member 17 projects within reach of the operators seat 38. Mounted on the shaft 38 is a drum 39 wound around which are chains 10 connecting at their lower ends with the members 9 whereby with the operation of the handle 37 the members 9 and all their connected parts may be raised or lowered by means of the hinges 5a.

Movable vertically through plates 41, disposed across the forward end of the beams l 1s a vertical )ost 4:2 bendme at its lower o end and having a pin or shaft 43 carrying a pair of cutting disks lift. From the upper end of the member l2 a chain lo pro- ]ects under a sheave 4G and thence around the drum 39 and thence over a sheave l-S and is then connected to the lower end of the post 42. By this structure, when the meinber 37 is operated and raises or lowers the members 9 and their connected parts, this will also raise or lower the disks lil in order that they may at all times maintain the same plane as the other parts of the machine. Secured to the lower end ot the member l2 are projecting eeler arms i9 adapted to project in the same plane as the disks Lift to maintain the proper horizontal position of the machine in the ditch since these eelers di) will follow along the side edges of the ditch as it is dup' and t-hus act as guides for the balance ot the machine. Thus as will be seen 'from the structure given the disks 44 will first proceed alone and loosen up the dirt along the sides ot the ditch to be dug and after a suitable depth is reached the members 4:9 guide the future action. After the side oi the ditch is dug and loosened by the disks de, the point 9st digs the level pla-ne of the ditch and with the forward movement of the machine this dirt is pushed up over the plate 23 where it dumps onto the conveyor 2G and with the operation of such conveyor by means ot the gear mechanism described, it delivers the dirt under the adjustable chute 30 from whence it is piled up on the edge ot the ditch. within their sides while the members 9 act as the guides for the conveyer. and to that end are provided with a plurality of rollers to support the conveyer. Also, as can be readily seen by means of the adjusting lever 1G the angle of the point Q-t may be turned either up or down according to the depth ot the ditch by moving the member 12 on its pivotal point 11 and also by changing The members l0 confine the dirtY the pivotal connection of the member 1G in one of the holes in the member 15. rlhe degree ot this angle may be correspondingly increased and decreased.

From the foregoing` description it will be readily seen that we have produced such a device as substantially fulfils the object ot the invention as set forth herein.

lVhile this specification sets forth in de tail the present and preferred construction oit' the device, still in practice such deviations from such detail may be resorted to as do not torni a departure from the spirit otl the invention.

Having thus described our invention what we claim as new and useful and desire to secure by Letters Patent is:

l. At device of the character described comprising a trame mounted on wheels, another trame hinged to said tirst named trame and pivotally mounted on an axle carrying wheels, a conveyor carried by said second named traine, a digging point carried by said second named frame and adapted to discharge on said conveyor, means for raising and lowering said second named trame and means tor tilting said digger point independently ot any movement otl said second named frame, as described.

2. A device of the character described comprising a main trame mounted on wheels. an independent frame hinged to said main frame, and being ournaled on an axle carrying wheels, means for raising and lowering said second named frame, a conveyer disposed in said second named frame, a digging point flexibly ournaled on. said second. named trame, means for inelining said digger point, said digger point discharging upon said eonveyer, as described.

in testimony whereof' we atliX our signatures in presence of two witnesses.
