PATENT OEEICE- JOSEPH IV. BAKER, OF EL PASO, TEXAS.

GRADING AND DITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 759,954, dated May 17, 1904.

Application filed January l5, 1904. Serial No. 189,151. (No model.)

To all wh/0m t 'may concern:

Beitknown that I, JOSEPH WBAKEP., a citizen of the United States, residing at El Paso, inthe county of El Paso and State oit' Texas, have invented a new and useful Grading and Ditching Machine, oi which the following is a specification. Y

This invention relates to grad ing and ditching machines such as are used for making, grading', and repairing roads, for digging' ditches, building levees, and for all similar purposes which require dirt to be excavated, elevated, and delivered at a distance from the point where the excavation is made.

The invention has for its object to provide a machine of this class which shall be simple in construction and eiiicient in operation; and with these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter described,and particularly pointed out in the claims.

In the accompanying drawings is shown a simple and preferred form of embodiment oli' my invention, it being understood that changes may be made as to the size, proportion, and exact manner of assemblage of parts within the scope of my invention and without departing from the spirit or sacrificing the utility of the same. j

In said drawings, Figure 1 is a plan view of a machinev constructed in accordance with my invention. Fig. 2 is a transverse sectional view enlarged. Fig. 3 is asectional view taken on the line 3 3 in Fig. 2, the carrier-wheel being omitted. Fig. f1 is a sectional detail view enlarged, taken on the line f1 l in Fig. l.

Corresponding parts in the several iigures are indicated by similar numerals et' reference.

In carrying out my invention I provide a The frame is su pported which they may be adjusted. By this construction it will be seen that the entire frame may be raised or lowered, as may be desired, and also that either end of said frame may be vertically adjusted independently oit' the other end. v

Adjacent to one side of the frame in proximity to the side beam 1 are disposed two plows 9 and 10, one oi' said plows being a right-hand plow and the other a left-hand plow. The beams 11 of said plows have pivotal connection at 12 with the side l of the frame, and said beams are provided at their front ends with ordinary means, as 13, for the attachment of d raft.

Rising from the side piece 1 is an upright 14, to which is pivoted a hand-lever 15, having at its lower end a T-head 16, the oppositelyextending arms of which are connected, by means o'l' links 17, with the rear ends of the plow-beams 11. It will be seen that by moving the lever 15 in one direction one of the plows will be depressed into operative or earth-engaging position, while by reversing the position ci' the lever the relative `position of the plows will be reversed. The lever 15 may be locked at any desired point of adjustment by means of an ordinary lock-dog '18, engaging a toothed segment 19, supported by the upright 14:. v

The opposite side beam 2 of the frame has an upright 20, provided with an inwardly-ex'- tending elbow 21, at the inner end of which is an inclined spindle 22, supporting the hub 23 of a large wheel 24, which constitutes the carrier of the machine. This wheel comprises besidcs the hub 23 a plurality of radiating spokes 25, connecting said hub with the rim 26, which hingedly supports a plurality of buckets 27, having inwardly-extending lugs 28, each bucket being provided with a pair of said lugs. The spokes ot' the wheel support a ring or annulus 29. Pivotally connected with the lugs 28 of each of the buckets 27 is a latch-bar 30, provided near its inner end with a notch 31, adapted to engage the under edge ol the ring 29, which latter thus serves to lock the latch-bar in operative position. The inner ends et' the latch-bars are connected with the hub ot the wheel by IOC means of coiled springs 32, whereby they are automatically drawn into operative or locked position, as will be readily understood.

Suitably swiveled on the spindle 22 above the hub of the wheel 24 is an arm or lever 33, carrying at one end a wheel 34, constituting a trip device for the latch-bars, in the pathof which the said wheel is disposed. The opposite end of the arm or lever 33 is connected by a rod 35 with an operating-lever 36. Said operating-lever is connected detachably with one side of the drivers seat 38 and may be shifted from one side of said seat to the other side, the seat being provided on cach side with a fulcrum pin or stud 39 for said lever and with a toothed segment40 to be engaged by a lock-dog 41, with which said lever is provided. rIhe seat 38 is carried by a pivoted 'supporting-spring 42, whereby it may be reversed, so as to face either end of the frame ofthe machine. then the seat is thus reversed, it obviously becomes necessary to shift the operating-lever 36 from one side of the seat to the other, the connecting-rod 35 being unhooked from the leverwhile such change is being effected. By means of this lever and connecting-rod the arm or lever 33, carrying the trip-wheel 34, may be adjusted to various positions in order that the latch-bar may pass into engagement with the trip mechanism at any desired predetermined point.

The frame of the machine is for strengthening purposes provided with suitably-disposed braces 47, and I desire it to be understood that in order to properly support the weight. of the carrier-wheel suitable guides and antifriction-bearings maybe used wherever they may be profitably employed. Such devices, however, are well knownin the art the drawings.

It will be observed that in the operation of this device the draft may be attached to either end of the machine, which may be thus propelled in either direction. The lower portion of the periphery of the carrying-wheel 24 is to be ladjusted in contact with the ground, and this may be effected by mounting the ends of the frame-bar 2 pivotally in boxes 43 upon the end pieces 3 ofthe frame. The weight of the wheel upon the elbow 2l will cause it to sag automatically into the proper earth-engaging position, and it may, if desired, be secured in such earth-engaging position by means of set-screws 44, engaging' the .boxes 43, or by any other suitable and convenient means. It is also obvious that the entire frame of the machine, by meansv of the crank-axles carrying the supporting-wheels, may be raised or lowered within the limits of the length of the cranks. To provide for such adjustment, the upright l4,carrying the plowsetting lever 15, is also preferably mounted tion passes over the ground, the plows having been previously set tothe proper position, the dirt turned by the operative plow will be deposited upon the buckets of the carryingwheel, which latter by contact with the soil will be rotated as the machine progresses, thus elevating' the soil and simultaneously carrying it to the opposite side of the frame. The latch-bars of the respective buckets will thus be engaged by the trip-wheel, which has been previously adjusted by the means described, being thereby depressed until the notches-3l become disengaged from the annulus 29,when the weight of the load upon the buckets will tilt the latter against the tension of the springs 32, thus discharging the load. Being relieved of the load, the weight of' the buckets will be overcome by the tension of the springs 32, whereby the latch-bars are redrawn into locked position, and the buckets 'will thus be ready to receive another load. g

It is obvious fromgthe foregoing that the machine by simply transferring the draft from one end of the frame to the other and reversing the position of the plows and seat may be operated with equal efficiency in opposite directions. The general construction is such that the machine is enabled to work very close to fences, hedges, and similar obstructions, and the dirt excavated may be deposited at a distance from the point where it is excavated equal to the diameter of the wheel, which in practice may be made of any desired size. The frame may be adjusted and the wheel may be tilted soas to elevate the dirt to any desired height within the capacity of the machine, which will thus be found extremely useful not only for road building and grading purposes, but equally for ditching and for building levees andthe like.
