THOMAS F. I-IAGERTY, OF NEW YORK, N. Y.; GEORGIANA. I. HAGERTY ADMINIS- TRATRIX 0F SAID THOMAS E. HAGERTY, DECEASED.

SELF-LOADING SCRAPER.

Application filed February 13, 1915.

To all whom it may concern:

Be it known that I, THOMAS F. HAGERTY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Self Loading Scrapers, of which the following is a specification.

This invention relates to self-loading scrapers to be used for street cleaning purposes, and it has particular reference to that class of scrapers which are wheel supported and are operated like a push cart to accumulate a load by scraping up loose material in front and carrying it into the body of a box-shaped scoop which, when loaded, may be tilted to discharge the contents into a receptacle.

One object of the invention is to produce a skeleton frame of simple and improved construction, said frame including side members which are spaced apart and provided with wheel carrying spindles, the scoop or scraper being pivotally connected with such frame.

A further object of the invention is to so construct the frame that it will support the free end of the scoop above the ground, said frame being provided with a scraper blade to engage the surface of the ground, thus obviating the wear on the edge of the scoop.

A further object of the invention is to simplify and improve the construction of the scoop, the sides and bottom being formed of one integral sheet of steel.

A further object of the invention is to provide the frame with pivoted legs or crutches whereby it may be supported while the scoop is being tilted to unload the same.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

vation of a scraper cart constructed in accordance with the invention, dotted lines being employed to show the position of the scoop when tilted to unload the same. Fig. 2 is a top plan view with parts broken away. Fig. 3 is a perspective detail view of the pivoted leg or crutch and related parts. Fig. t is a side elevation of the device seen from the opposite side to that shown in Fig. 1. 5 is a longitudinal sectional view taken. on the line 55 in Fig. 2. Fig. 6 is a horizontal sectional view taken on the line 66 in Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame F of the improved device is substantially rectangular, comprising the side members 15, bottom cross bar 16 and top cross bar 17. The frame may be conveniently formed by bending from a single piece of channel iron or other appropriate material. The side members 15 are provided with spindles 18 carrying the ground wheels 19, said spindles being positioned intermediate the ends of the side members. The cross bar 17 constitutes a handle whereby the device may be conveniently propelled.

The side members of the frame are connected intermediate the spindles 18 and the cross bar or handle 17 by a cross bar 21 on which the box-like receptacle or scoop R is pivotally supported. The side members of the receptacle are connected together at their upper end portions by a front apron 22 having a handle 23 whereby the scoop may be manipulated in tilting. The bottom portion of the scoop is inclined downwardly and forwardly, and the forward or lip portion thereof rests on a scraper blade 24 detachably connected with the top of the cross bar 16 of the frame. The scoop has an upwardly extending neck 25 which is preferably provided at its upper edge with a bead or flange 26 below which a clamping ring or band 27' is arranged for the purpose of retaining in position an inverted bag or a similar receptacle.

Pivotally mounted on the cross bar 21 adjacent to the outer faces of the frame members 15 are legs or crutches 28, each having at its upper end a laterally extending arm 29. These legs are normally moved in a forward direction so as to hold the lower ends thereof clear of contact with the ground by the action of springs 30 which may be ordinary coiled contractile springs, each having one end connected with the frame and the other end with one of the legs 28. The legs may be swung to a ground engaging position, as seen in dotted lines in Fig. 1, and the frame will thus be supported in a non-tiltable condition while the receptacle is being tilted for the purpose of discharging the contents. The laterally extending arm 29 constitutes a stop member which, by engagement with the side member of the frame, will limit the swinging movement of the le in a rearward direction.

Pivotally connected with the scoop or receptacle adjacent to the lower edge of the apron 22 is a gate 31 having adjacent to its upper edge an upwardly extending arm or crank 32 which is pivotally connected to the forward end of an operating bar 33, the rearward end of which is guided through a keeper 34: on the rearward end of one side of the scoop, the rearward end of said operating rod terminating in a handle 35 whereby it may be manipulated to move the gate to an open or to an obstructing position with regard to the rearward portion of the scoop. The rod 33 may be provided with notches 36 adapted to engage the keeper for the purpose of looking or retaining the gate in an open or in a closed position, as may be desired.

From the foregoing description, the ope1 ation and advantages of this invention will be readily understood. The frame, it will be seen, is of extremely simple construction, and it will support the scoop or receptacle practically clear of the ground, the scraper blade 24 attached to the cross bar being in a position where its ground engaging edge will effectively scrape the surface of the ground. Should obstructions, such as frozen matter,

be encountered, the operator, by lifting up the handle 17, may readily pick up the same, the frame and scraper being rigidly connected. By pushing the device over the surface of the street, rubbish and litter of all kinds may be conveniently gathered in the receptacle, it being obvious that by occasionally bearing down on the handle so as to lift the forward end of the scoop, the accumulating material may be thrown back into the rearward part of the scoop, the gate 31 having been previously moved to an open posi tion. When the material has been thrown back into the rearward portion of the scoop, the gate 31 is restored to its obstructing position, as will be readily understood. When it is desired to discharge the contents of the scoop the legs or crutches 28 are moved to ground engaging position, as seen in dotted lines in Fig. 1, holding the frame stationary, and the scoop may then be tilted, as shown, thereby discharging its contents either into a can or other receptacle previously placed in posrtlon or into an inverted bag which has been previously connected with the neck of the scoop by the bag holding element 27. The device is capable of being operated in a thoroughlv effective manner and with less exertion and strain on the part of the operator than is usually required to accomplish similar results.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a substantially rectangular frame, the side members of which are provided with wheel carrying spindles intermediate the ends thereof, a cross bar connecting the side members intermediate the spindles and the upper end of the frame, a groundengaging scraper blade fixed on the lower cross bar of the frame, a scoop pivoted on the intermediate cross bar and having an inclined bottom, the
