Specification of Letters Patent.

AUTOMATIC DUMPING DEVICE.

Patented uly 31, 1917'.

Application filed September 5, 1916. Serial No. 118,503.

To all whom it may concern:

Be it known that I, HERMAN O. E. BEIN- DORF, a citizen of the United States, residing at Homestead, in the county of Pueblo and State of Colorado, have invented certain new and useful improvements in Automatic Dumping Devices, of which the following means with which the bucket directing means aforesaid cooperates to hold the latter maintaining the bucket'in an outwardly swung position in-relation to the well or mine shaft while the bucket is being dumped, said dumping action being. also automatic in character so that the apparatus servesnot only to facilitate the operations but to effect saving of time and'labor for carrying on the same.

In addition to the foregoing it is comprehended to employ that type of locking means which will automatically release the bucket directing means when the bucket, after dumping, is again actuated to returnit toi position within the shaft.

T heseand such other objectsasmay hereinafter appear are attained by the novelrconstruction, combination andarrangement of parts .to be hereinafter specifically described and claimed. Reference willnow. be had to the accompanying drawings forming a part of this specification, wherein Figure 1 is aside elevation of an apparatus constructed in accordancewith my invention, parts being broken away and shown insection; I V

Fig. 2 is a front elevation; Fig. 3 is an enlarged vertical viewpntheline -3.3 of Fig. 2;

sectional Fig. ais atop plan view. of the apparatus ands Fig. 5 is adetail view-in side elevation-of I cally;-describing the. invention, 1 designates a suitable gallows frame at theupper portion of which are arranged spaced standards 2 between which is mounted a sheave3 accommodating the hoisting cable 4; carrying the bucket 5. For the purpose of convenience in this description the partsl and 5 will be referred to as the bucket hoist. Projecting laterally from the frame 1 are a pair of supporting arms 6 at the end portion of which is supported -a transverse support 7 the latter having trunnions at its, eXtremities journaled in the arms 6 to permit, of rotation of said transverse member. Depending from this member 7 is a thrust arm 8 which preferably consists of spaced side members 9 converging at thelower extremities between which is received a friction roller 10 adapted to cooperate with the hoisting cable in the operation of the apparatus, as will be hereinafter more fully explained.

It, will be observed by reference to Fig. 1' that the arm 8 extends downwardly, at an incline so that the lower extremity will normally lie in the path of movement of the. bucket as it is raised from the excavation, the arm being held in suchnormal position by the stop member 11 which is supported by the platform support 12.; It. will be un-' derstood that upon this last mentioned support the necessary mechanism for mechanically operating the buckethoist may be positioned, as diagrammatically indicated at l3.

Upon lifting movement of the bucket, hoist the arm 8 is impinged by the bucket, a cushion spring 14: being provided just above the bail of the bucket to take up the impact. After impingement as. above referred to, the arm 8 is carried upwardly with the bucket hoist moving in an are ,at one side of the gallows frame. The arm thrusts the bucket laterally from the frame outof the planeof its initial path of movement and whenthe arm has reached the horizontal dotted line position shown in Fig. 1 it is automatically'engaged with a locking member 15 which is supported between the lower end portions of the standards 2, as shown most clearly in Fig. 2 of the drawings. Thelocking member l5 is held to one side so as not tointerferewith the operation of the cableby meansflof a member 15 consists of the lower, hook terminal 15 and the upper curved arm 15,

said locking member normally assum ng: a

vertical position so as to lie in the path of movement of the cross bar 17 carried by the side members 9 of the arm 8. This bar automatically engages with the hooked eX tremity of the locking member when the arm reaches the horizontal position above referred to, and upon lowering movement of the bucket toward its dumping position.

At one side of the frame is conveniently arranged the bucket dumping means or platform 18 which is pivotally supported at one side as indicated at 19 and provided with a counter-balance weight arm 20. The platform 18 furthermore is provided'with diverging guide arms or standards 21 so that as the bucket 5 is lowered it will be guided by said standards onto the platform 18. This platform is immediately overbalanced and the material from the bucket thereupon dumped. The operation of returning the bucket to its normal excavating position involves the raising of the bucket until it impinges the outer end portion of the arm 8 which is held in its horizontal position by the member 15. A continued lifting movement of the bucket hoist raises the arm 8 to the inclined dotted line position shown in Fig. 1, whereupon the rod 17 passes over the curved upper end of the locking member 15. Lowering movement of the bucket is now free to take place inasmuch as the rod acts upon. the rear edge of the locking member to move it out of engaging position with respect to the rod and the arm will consequently return to its normal full line position shown in Fig. 1 as the bucket is lowered to its initial position.

It will be apparent from the foregoing description that the excavating operation above described may be carried out by a single operator inasmuch as the dumping operation is entirely automatic and under the control of the bucket hoist. The apparatus is extremely simple in its construction and may readily be used for various purposes aside from excavating operations, such for instance as removing material from cars, tanks or other receptacles by means of a vertically operated hoist.

Slight changes may be made in the details of construction without departing from the spirit of the invention and within the scope of the appended claims.

Having thus described my invention, what I claim as new is 1. In apparatus of the class described, the combination with a frame and bucket hoisting means, of an arm movable incident to hoisting action for directing the bucket to dumping position, a hook member mounted on said frame for free swinging move ment and engageable at one end with the arm to support the same during lowering of the bucket for dumping, the other end of said hook member being arranged for engagement by the arm incident to lifting of the bucket from the dumping position to thereby shift the engaging end of said hook member out of engaging relation with respect to the arm, whereby to effect release of the latter.

2. In apparatus of the class described, the combination with a frame and bucket hoisting means, of actuating means arranged in the path of movement of the bucket hoist operable during hoisting movement to positively direct the bucket to dumping position, and means engageable with the actuating means to hold the latter during dumping of the bucket, said holding means having a portion arranged to be impinged upon movement of the actuating means incident to return of the bucket to initial position to thereby effect release of said actuating means.

3. In apparatus of the class described,the combination with a frame and bucket hoist, of means for directing the bucket to dumping position comprising a member pivotally connected to the frame and inclining downwardly into the path of movement of the bucket for impingement thereby, said member being operable with the bucket hoistto positively thrust the bucket laterally away from the frame during hoisting action into dumping position, and locking means carried by the frame in position to be engaged by the pivoted member aforesaid to sustain the latter during the dumping operation, said locking means having a member and an arm at its other terminal engageable by said pivoted member when the latter is actuated to lift the same whereby to withdraw the hooked terminal from its engaging position to thereby release said pivoted member.
