Y EXCAVATING-MACHINEQ SPECIFICATION forming part of Letters Patent No. 768,362, dated. August 23, 1904. A plication filed October 31, 1903. Serial No. 179,376. (No model.)

To all whom it may concern:

Be it known that 1, JAMES PORTERFIELD Gon- DON, acitizen of the United States, residing at Florence, in the county of Fremont and State of Colorado, have invented a new and useful Excavating-Machine, of which the following is a specification.

The invention relates to improvements in excavating or ditching machines.

The object of the present invention is to improve the construction of excavating or ditching machines and to provide a simple, inexpensive, and eflicient machine of this character designed for operating on land and capable of operation wherever it is possible to drive a vehicle. 1

Another object of the invention is to enable the ditching-machine to be operated by a stationary enginelocated at a point beyond the place operated on and to provide a combined draft and hoisting rope or cable for propelling the machine and for operating its scoop or shovel.

The invention also has for its object to provide a ditching-machine in which the weight of the shovel or scoop will be utilized after the same has deposited its load and while returning to its starting-point for actuating the means for conveying such excavated earth from the shovel or scoop to the wagon or cart into which the excavated earth is discharged.

Furthermore, it is the object of the invention to provide means under the control of the operator for enabling the discharge of the excavated earth to be made at any desired point within the limits of the movement 'of the carrying means for conveying the earth from the scoop or shovel'to the wagon or cart.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of I parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being under-. stood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of a ditching or excavating machine constructed in accordance withv this invention. Fig. 2 is a rear elevation of the same. Fig. 3 is adetailplan view illustrating the arrangement of the scoop or shovel and the receptacle of the frame when the former is discharging into the latter. Fig. 4. is an enlarged detail view illustrating the manner of mounting the scoop or shovel. Fig. 5 is a sectional view of the same. I

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a main or supporting frame designed to be constructed of any suitable material, either wood or metal, and mounted upon frontand rear wheels'fl and 3, the front wheels being arranged on the spindle of a short axle 4 and the rear wheels being mounted on an elongated axle 5. The elongated axle may be of any desired length, and when necessary axles of different lengths may be employed, and the said rear axle is provided at intervals with perforations 6 and is arranged between parallel uprights7 and 8, disposed in pairs at the rear of the frame and located at opposite sides thereof. The uprights 7 and 8 are provided at intervals with perforations 9, adapted to receive fastening devices 10, which also pass through perforations of the rear axle, and by this construction the rear of the frame may be raised and lowered and may be adjusted laterally to enable the shovel or scoop 11 to operate at different points, whereby a ditch or trench may be excavated the desired width and depth. In practice the machine moves forward as the shovel or scoop cuts its width, and this operation is repeated until the necessary width is out. One layer after another is excavated in this manner until the necessary depth is cut, the frame being lowered after cutting each layer to enable the shovel to operate at an increased depth.

The shovel or scoop is carried by an oscillatory arm 12 of a transverse shaft 13, which is journaled in suitable bearings at opposite sides of the frame, as clearly indicated in Fig. 2 of the accompanying drawings, the frame being composed of two sides spaced apart to provide a way for the shovel and the long oscillatory arm 12 and connected beyond the shovel and the arm by suitable cross-pieces. The shaft 13 is provided at one side of the machine-with an extension 1i, and it has a shortarm 15 at the end thereof. This arm 15 is connected by a link 16 with an approximately horizontal arm 17 of a crane 18, which carries a receptacle 19 for the excavated earth and which is operated bythe said shaft 14, whereby when the shovel or scoop is swung upward the crane is caused to swing inward to receive the contents of the scoop or shovel, and when the scoop or shovel is swung downward the crane will be swung outward to discharge its load. The bucket, shovel, or scoop,

which may be of any desired construction, is

preferably approximately cylindrical and tapered, as shown, and it is secured to arms 20 of a sleeve 21, the arms being disposed in pan's at the sides of the scoop or shovel, whereby the latter is rigidly connected with the sleeve.

23, which is arranged at the outer end of the sleeve, sufiicient space being provided between the plug or closure 23 and the inner end of the enlargement of the bore or opening to acconnnodate a nut 24. The nut 24 engages the outer end of the arm 12 of the transverse shaft. The sleeve is first placed on the arm 12 and is then moved inward sufiiciently to expose the outer threaded end of the arm. The nut 24 is then applied to the arm, and the sleeve is drawn outward to carry the nut into the enlargement of the bore or opening, after which the plug or closure is applied to the outer end of the sleeve. This will retain the parts in proper position and will permit the sleeve to rotate on the arm 12 of the shaft, as hereinafter explained. The inner portion of the sleeve is provided with exterior screwthreads 25, and the saidsleeve is extended beyond the screw-threads and reduced, as shown, the reduced portion receiving acoiled spring 26, having one end connected with the sleeve and its other end fixed with relation to the arm 12. The outer end of the spring is secured to a projection or finger 27 of the inner reduced portion of the sleeve, and the inner end of the spring is secured to one of a pair of spindles 28 and 29, which are fixed to a cross-head 30 of the arm 12. The spindle 28 receives the inner end of the coiled spring, and the other spindle, 29, is provided with a stop'31, arranged in the path of the finger or projection 27 and normally engaged by the same. The spring holds the finger or projection 27 against the stop 31 when it is free to act, and it thereby maintains the bucket,

scoop, or shovel in proper position for excavating, and 1t returns the bucket, scoop, or

shovel to such position after the same has been partially rotated. as hereinafter explained, to dump the excavated earl 11 into the. receptacle of the crane. 'lhe cross-head 30 is suitably lixed to the arm 12 of the shaft 13, and the spindles 28 and 29, which are lixed to the cross-head, receive guide-wheels 32, forming anti friction devices and arranged to run on curved tracks 33 and 3%, whereby the arm 12 is held against lateral movement and is caused to swing longitudinally of the machine.

The frame of the machine is provided at one side with a curved rack 35, arranged to n ceive a gear-wheel 36, which is provided with interior screw-threads 37 for engaging the exterior screw-threads of the sleeve, whereby when the arm 12 is oscillated the gear-wheel 36 will be rotated and will be moved inward and outward on the sleeve as the arm 12 is swung backward and forward. The gearwheel is provided at its outer face with a clutch 38, which is adapted to engage a clutch member 39 of the sleeve, the clutch member 39 being preferably secured to the sleeve by a set-screw 10 and being provided at its ongaging face with a shoulder for engagement with the clutch member 38. The clutch member 38 is provided with a beveled outer face, and it has a shoulder at one end for engaging the clutch member of the sleeve.

When the arm 12 arrives at an approximately horizontal position, as illustrated in dotted lines in Fig. 1 of the drawings, the gear-wheel will have reached the outer end of the threaded portion of the sleeve and will have engaged the clutch member 39 to partially rotate the bucket,scoop, or shovel against the action of the coiled spring for discharging the contents of the said bucket, scoop, or shovel into the receptacle of the crane. This movement carries the finger or projection 27 away from the stop 31, and as soon as the bucket, scoop, or shovel descends the clutch member 38 of the gear-wheel will release the sleeve and permit the scoop or shovel to be returned by the coiled spring to its position longitudinally of the machine for making another cut. The curved rack is substantially quadrant-shaped, and its curve slightly recedes from the arc of a true circle to accommodate itself to the inward and outward movement of the gear-wheel. As the arm 12 descends the gear-wheel moves inward, and the curved rack is arranged to receive the gearwheel properly at each point along the are in which the arm 12 swings. The sleeve is connected with one end of a rope or cable 41 by a collar 42, having a suitable eye for the reception of the rope or cable and adapted to permit the sleeve to turn freely within it. The rope or cable extends upward to a guide-pulley 43, located at the top of the machine at the front thereof, the frame of the machine being preferably extended, as shown. The cable or rope extends to a suitable stationary engine, (not shown,) and it serves both as a provided with an inclined shaft 44, having its ends journaled in bearings 45 and 46, located in the same transverse vertical plane. The lower bearing 46 is offset laterally beyond the upper bearing, and theshaft and the crane are thereby set at an inclination, and when the crane swings outward to its discharging position the receptacle is slightly elevated and is adapted to cause the crane to swing inward when the same is free to move.

The crane is provided with upper and lower inclined bars 47 and 48, the lower bar 48 being extended outward through an eye 49 of the upper bar to form an arm or support 50, which is provided with a depending stop or rest 51, set at an angle or inclination and adapted to limit the tilting movement of the receptacle 19, as illustrated in dotted lines in Fig. 2 of the drawings, thereby lessening the movement of the tilting receptacle and enablingv the machine to be built somewhat lower than it could be were the receptacle allowed to swing downward to a vertical position. In other words, the receptacle will clear a cart or wagon when it is in an inclined position, whereas it might strike such cart or wagon when in an upright position.

The receptacle-is provided near its center with eyes for the reception of a pivot 52 of the arm or support 50, the inner portion of the pan being preferably slightly heavier than the outer portion, whereby the weight of the pan or receptacle will operate to retain it in the position shown in full lines in Fig. 2. The receptacle is held in an upright position by means of a dog 53, pivoted at its lower end to the arm or support and having an engaging upper portion which extends over the upper edge of the inner side of the receptacle. The dog is also provided with an arm 54, extending outwardly beneath the receptacle, and an operating cord or rope 55 is connected with the upper end of the dog and is adapted tobe pulled to release the receptacle and to swing the inner side thereof upward to dump the receptacle.

The receptacle is provided at its outer side with a hinged gate 56, carried by a pair of arms 57 of a bell-crank lever. The arms 57 are provided at their outer ends with eyes to receive pivots 58 of the gate 56, and they are connected at their inner ends with a transverse shaft or pintle 59. An arm 60, which is arranged at right angles to the arms 57 and which is preferably formed integral with one of them, extends upward from the same and is provided with a projection 61, which is arranged to engage a lug62 of the receptacle, as illustrated in dotted lines in Fig. 2 of the drawings. The gate 56, which is connected at the top with the arms 57, has its lower edge engaging keepers 63, which firmly hold the gate in its closed position. When the arm 60 is swung rear- Ward by a cord or rope 64, the gate 56 is lifted out of engagement with the keepers 63 and is permitted to swing outward to allow the contents of the receptacle to discharge into a cart or wagon or upon the ground, if desired. The operating cords or ropes 55 and 64, which for convenience of illustration are shown extending horizontally from the parts to which they are connected, will in practice extend to the platform of the machine in order to enable the operator to dump the receptacle when desired. After the receptacle has discharged its contents the operating cord or rope 64is pulled to engage the projection 61 with the lug 62 and return the receptacle to its upright position. When the operating cord or rope 64 is released after returning the receptacle to its upright position, the gate will drop back into engagement with the keepers.

The crane is positively drawn outward to its discharging position by the weight of the arm 12 and the shovel or scoop when the said arm 12 swings downward, and when the arm is swung upward the crane is gradually permitted to swing around to the machineto receive the contents of the scoop or shovel. By this construction the oscillation of the crane is automatically controlled by the scoop or shovel, and as the latter vibrates longitudinally of the frame the receptacle will be moved transversely of the same. If desired, a plurality of shovels of diiferentkinds and sizes may be provided, and the connection between the shovel and the arm or member 12 of the shaft 13 will permit the shovels to be readily changed when desired.

In order to prevent the ropeor cable 41 from extending in a straight line from the pulley 43 to the outer end of the arm 12 and decreasing the .power or leverage when the arm 12 is in an upright position, as illustrated in Fig. 1 of the drawings, a guide 65 is employed. The guide 65 is substantially segmental and preferably consists of a curved block or piece connected by bars 66 and67 with the arm 12. The bars 66 and 67 are bolted or otherwise secured at their outer ends to the block or piece and are provided at their inner ends with eyes 68 and are secured by set-screws 69 to the said arm 12. The curved block or piece of the guide is provided at its outer face with a groove to receive the rope, and this peripheral groove is arranged concentric with the are described by'the arm 12 at the collar 42, where the rope or cable is secured. When the arm 12 is in substantially an upright position, the upper end of the curved body portion and the guide 65 are located beneath and slightly in rear of the guide-pulley 43, and when power is applied to the rope or cable the same will exert substantially a direct upward pull on the guide, and the leverage of the arm 12 will be substantially the same at every point within the limit of its oscillation. The set-screws ($9 p'ermit the guide 65 to be adjusted, and the said guide 65 is adapted to clear the guide-pulley 43, and

, it does not interfere with the oscillation and operation of the shovel.
