DUMPING-SKIP.

Application filed April 20, 1908.

Specification of Letters Patent.

Patented Oct. 2'7, 1908.

Serial No. 428,179.

To all whom it may concern:

Be it known that I, WILLARD D. LOCK- woon, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented a new and useful Dumping-Skip, of which the following is a specification.

The present invention relates to improvements in dumping skips, and it has for its principal object, the provision of an extremely simple, inexpensive, and efficient device of that nature which is closed at one end and has a movable door at the other end, the door being so connected with the skip as to open automatically when the latter is in position to dump its contents, and also to be capable of movement into open position when the skip is upon the ground, to permit the loading of the skip.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which corresponding parts are desig nated by the same reference characters throughout the several views.

Of the said drawings, Figure 1 is an isometric view of the complete ski Fig. 2 is a similar detail view of the oor and bail. Fig. 3 is a side elevation of the skip, showing the door closed. showing the skip tilted, and its door 0 ened. Fig. 5 is a side elevation showing the oor of the skip thrown back.

Referring more particularly to the drawings, A designates the skip, B its door, and C the bail to which the latter is secured. The skip has its rear end closed, and its top and front end open, the door B tending to retain the contents of the skip from being discharged until the skip is tilted. To the under face of the bottom wall of the skip is secured a longitudinally-disposed metal strap 9 whose ends project beyond the side edges thereof'and are bent upwardly against the side walls of the skip as shown. The terminals of said I bent ends, in like manner, project above the upper edges of the side walls and are provided at such point with lateral pivot pins f which extend towards each other and fit in openings formed in the intersecting lower ends of the bail legs (1 and the rear ends of the braces b which are arranged at right angles thereto and are fastened at their forward ends to the wings e of the door B. These wings, which are formed by bending the ends of the door at right angles to the body portion there- Fig. 4 is a side elevation of, extend rearwardly and are further connected with the bail legs by upwardly-hr clined braces a whose free ends are fastened to the upper ends of said legs. The door is so proportioned to the skip that its wings fit closely against the side walls of the skip. The strap 9 above referred to is disposed slightly in advance of the center of gravity of the skip.

The bight portion of the bail C is provided with an upstanding staple with which is engaged a depending hook carried by the pulley around which the cable E is trained. In like manner, the rear wall of the skip is provided with a staple with which is engaged a hook fastened to one end of the cable D, the last-mentioned staple being connected by a chain F with a depending staple set into the bight portion of the bail directly beneath the first-mentioned staple. This chain, therefore, supports a portion of the load, as will be apparent.

In loading the skip, which rests upon the ground during such operation, the two cables are unhooked from the sta les and the door swung upwardly and bac iwardly into the position shown in Fig. 5, the open front end and top of the skip permitting the latter to be readily fitted.

When the skip has been filled, the door is swung downwardly, so as to completely close said end, after which the hooked ends of two cables are reeengaged with the staples. The loaded skip is then raised to the desired po sition by means of the cable E, the chain F preventing the skip from tilting rearwardly during its upward movement. The cable D is then held fast by the operator, and the cable E lowered, or the latter cable can be held fast and the cable D raised, as preferred, whereupon the skip will be swung rearwardly upon its pivots f, as shown in Fig. 3, its front end swinging downwardly away from the door B, which is thus opened, the contents of the skip being discharged therefrom during such movement, as will be understood. At the completion of such discharge, the cable D is released, permitting the skip to assume its normal position, with its front end closed.

What is claimed is:

The combination, with a skip having an open top and front end, of a bail having its legs pivotally connected at their free ends to the side walls of the skip forwardly of the center of gravity of the latter; a door arb ra'niged to open and closebsaid front enill, the bight portion and said rear Wall.
