SPECIFICATION forming part of Letters Patent No. 774,431, dated November 8, 1904 Application filed February 25,1904: fierial No. 195,299. (No model.)

To aZZ w/wm it may concern.-

Be it known that I, FRED M. IRELAND, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Excavating-Bucket, of which the following is a specification.

M invention relates to excavating imple-- ments, and has for itsobject to provide adevice which 1s serviceable for use both as an excavator and a conveying bucket. To this is converted into a bucket adapted to be suspended by a tackle from a derrick and to carry and discharge its load like the common bucket. These various contrivances are constructed as illustrated in the accompanying drawings, hereby referred to as a part of this specification, and are hereinafter fully described and claimed.

In the drawings, Figure 1 is a side elevation of my excavating-bucket. Fig. 2 is a rear end elevation. Fig. 3 is a perspective of my invention looking at the same from the front end, and Fig. 4 illustrates the manner of using my invention.

Referring now to the letters as designating the parts described, the body (Z is made of sheet-iron of suitable strength, the bottom (4 thereof being made flat, so as to adapt the same to be dragged over the ground in suitable position for doing the excavating-work.

Hingedly secured to the front end of the body a is a plate a or plow, provided with a rigid arm 0, connected by a link (Z with a lever f, pivoted to a bracket secured to one side of the body. The lower end of the lever f is bent, as seen in Fig. 1, and the end of thelink (Z connecting therewith is forked.

The function of the plow Z) is to plow or dig up the ground in advanceof the travel of the excavating-bucket and also to feed the dug up dirt into the body of the bucket.

The plate 7) may be thrown in active and inactive position by manipulating the arm f. When my excavating-bucket is started on its work, the lever f is set in the position in which it is shown in Fig. 1. The operator may also when necessary bear down upon the extremity of the lever f, so as to hold the plow more effectively to its work. i

As soon as the bucket-body has become sufficiently filled with excavated'material the operator reverses the lever f and by so doing lifts cutting edge of the plow?) off the ground.

The excavating-bucket consequently does no further excavating for that trip, but merely proceeds to its place of discharge. There is also attached'to the front end of the body of the bucket a hauling yoke or bail it.

To the rear part of the body are pivotally secured on each side runners j. The front ends of said runners j are pivoted in place, while the rear ends of the same are connected, by means of links it, with the lower extremities of a yoke-like lever Z, said lever being pivoted to lugs m, riveted on each side of the body.

The runners j are provided for facilitating the starting of the excavating-work with my implementthat is to say, supposing the surface of the ground which is to be excavated to be level, to make the first deep cuts into the surface the body of my excavating-bucket should be tilted, so as to throw the greater part of the weight of the body onto the front (plowing) end. After the deep cuts have been made the runners are returned to their normal position and only again thrown into their active position when required for making further deep cuttings. Said runners j are thrown into and held in their uplifting position by manipulating the lever Z, as shown in Figs. 1 and 3. The lower ends of the two parts or branches of the lever Z are pivoted at Z. Beyond said points the links Z: are pivoted to the said ends of the lever. The lower ends of the links it are connected with the ends of the runners j. The upper ends 1c of said links are bent at right angles, and said bent ends are inserted in holes therefor made in the two ends of the lever Z. The bent ends are threaded and secured in place by bolts k At the extreme ends of each branch of the lever Z are provided rigid hooks Z Thus when the lever Z is thrown into the position indicated in broken outline in Fig. 1, placing the runners in the position shown by their dotted outline, the hooks Z will engage with the links 7: and the weight of the thrownback upper end of the lever Z will then cause said parts to remain in the described engagement and securely hold the runners j in their active position.

Hinged to the back end of the bucket-body is a door 72, provided with handles a. The door is locked by means of a spring-latch 0, the door a being made with a projecting portion n having an aperture 19, adapted to receive the latch 0.

The back end of my bucket is further provided with a ring q, to which to secure the ends of the haul-back cable.

The operation of my device is as follows: My excavating bucket is hauled over the ground by a donkey-engine or other suitable means, the hauling-line being guided through a snatch-block r, secured in suitable position.

Upon the excavating-bucket having arrived at the end of its haul the hauling-cable is released from the snatch-block 1' and the bucket, filled with excavating material, lifted by means of a derrick-tackle. The derrick is next swung around, so as to bring the excavating-bucket in position for discharging into a wagon or other suitable conveyance, whereupon the latch 0 is lifted to drop the door n and allow the contents of the bucket to discharge. The bucket is then hauled back to the starting-point, the hauling-line is reinserted in the snatch-block r, and the excavating operation is resumed.

The chain 2' is provided to hold the bucketbody in straight perpendicular position while suspended from the derrick-tackle. For this purpose one end of the chain Z is permanently secured to the body, and the other end has a ring 71 which is placed on the loop 5 of the bail it.

Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In an excavating-bucket, the combination of a semicylindrical body, having a flat bottom; a plow-plate hinged to the front edge of the bottom; means for controlling and adjusting the position of said plow; runners pivoted to the two sides of the rear end of the body; means for dropping the runners, so as to tilt the body on its front end; a hinged door closing the rear open end of the body, and a latch for the door.

2. In an excavating-bucket, the combination of a semicylindrical body, having a flat bottom; a plow-plate hinged to the front edge of the bottom; a lever f pivoted to one side of the body, jointed connections of said plowplate therewith, whereby the plow-plate may be suitably positioned and controlled; runners 7' pivoted to the two sides of the rear end of the body; a yoke-like lever Zpivoted to the body; means operatively connecting said lever Z with said runners, whereby the latter may be dropped, so as to tilt the body on its front edge; a hinged door closing the rear open end of the body; a latch therefor, and means for perpendicularly suspending the body from a tackle.

3. An excavating-bucket comprising a semicylindrical body, havingaflat bottom; a plowplate 6, hinged to the front end of the bottom; a lever f pivoted to one side of the body; jointed connections of said plow-plate with the lever f, whereby the former may be suitably positioned and controlled; runners j pivoted to the two sides of the rear end of the body; a yoke-like lever Z, pivoted to the body; means operatively connecting said lever Z with said runners, whereby the latter may be dropped, so as to tilt the body on its front end; a hinged door closing the rear open end of the body; a latch therefor; and a bail it and a stay-chain t for perpendicularly suspending the body from a tackle.

4:. An excavating-bucket comprising a semicylindrical body, having a fiat bottom; a plowplate 6 hinged to the front edge of the bottom; a lever f pivoted to one side of the body, a rigid arm 0 on the plow-plate; a link (i connecting said arm with the lever f, so that the plow-plate may be suitably positioned and controlled by the lever f; runners j pivoted to the two sides of the rear end of the body; a yoke-like lever Z pivoted to the body; links in connecting the ends of the lever Z with the movable ends of the runners, and hooks or stops Z on said lever ends, so that said runners may be dropped, to tilt the body on its front end by operating the lever Z; a hinged door 22, closing the rear open end of the body; a latch therefor and a bail h, and stay-chain t' for perpendicularly suspending the body from a tackle,

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.

FRED M. IRELAND.
