DUMPlNG-WAGON;

. SPEGIFICATION forming part of Letters Patent No. 640,129, dated December' 2.6, 189i?.

Application tiled January 28, 1898 Serial No.'668,270 (No model.)

To all whom it may concern:

Beit known that we, Amon H. Ganan-EY and CHARLES O. BARTLETT, citizens of the United States, and residents of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful improvements in Dumping-Wagons, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in dumping-wagons; and the object of the invention is to provide a construction in which the dumping-receptacle may be bodily moved beyond one side of its supporting-frameto discharge its contents. By this arrangement we avoid the necessity means for lifting the weight of the dirt-receptacle and the material contained therein, as would be necessary if the contents were discharged through an opening in the end or side of the receptacle.

The invention, which consists inthe peculiar construction and arrangement of parts that will be hereinafter described, may be used in connection with various mechanisms, and in the drawings we have illustrated the same as combined with a street-sweeping siachine of that type in which the material raised by a rotary brush is delivered to an elevator or conveyer, by which it is deposited in the dumping-receptacle. r

Figure 1 isaperspective view ot a machine embodying our improvements, the rotatable dirt-receptacle being shown in position to discharge its contents and the bottom plates thereof being removed. Fig. 2 is a side elevation' of the machine. Fig. 3 is a view illustrating the manner of securing the removable bottom plates in the rotatable dirt-receptacle. Fig. 4 is a longitudinal sectional view of the machine. Fig. 5 is a detail view of the bar for locking the dirt-receptacle in position to be loaded.

Like letters and numerals of reference indicate corresponding parts in all the figures of the drawings, referring to which- 1 designates the main supporting-frame of the machine, it being provided with suitable carrying-wheels, which are mounted on axles i2. Upon this frame are mer-stad the fotary of providing special cleaning-brush, the conveyor for elevating the material lifted by said brush, and the receiver or receptacle for holding the dirt until a sufficient quantity has been accumulated. The axle A of the brush 7 is carried by hangers or links 8, ,which are their upper ends to the rear axle 2, and suitable means under the control of the driver, at the forward end of the machine, are provided for causing said brush-supporting hangers to vibrate about the axis of said rear axle, and.

thereby vary the position of the brush relative to the frame of the machine and the surface to be cleaned. In the embodiment of the invention herein illustrated this adjusting means comprises two rods or links 90, connected at their lower ends to the axle A of the brush 7 and having their upper ends attached to ears or lugs on a rock-shaft 10, that is mounted in suitable bearings on the main frame l. he shaft 10 is provided at one end with an arm 11, which is connected, by means of a rod 14, with an adj usting-bar 13, extending longitudinally of the machine. Near its forward end this bar 13 is provided with aloosely connected at series of rack-teeth 15, and a pinion 16 is mounted on a suitable support on the frame 1 and arranged to mesh with said rack 15. By rotate the pinion 16, and thus move the adjnsting-bar 13 longitudinally, thereby rocking the shaft 10 and adjusting the brush 7 as desired. The arm 11 is preferably provided with a series of perforations, so that the rod 14 may be connected therewith at any desired distance from the axis of the shaft 10 to vary the amount of leverage applied to said shaft.

Rotary motion is imparted to the cleaningbrush by means of a gear 5, suitably secured to the rear axle and me hing with a pinion 9, mounted on the brush-axle. This arrangement of parts enables the brush to be elevated or vibrated about the axis of the rear axle in the manner above described without destroying the connection between its pinion 9 and the master-gear 5.

3 designates the' casing or inclosing box for the endless conveyor, by means of which the dirt raised from the ground by the brush 7 is carried to the receptacle provided therefor. This' casing is preferab mcans of a hand-wheel 17 the driver canl IOO on curved lines toward and projects partially under the cleaning-brush 7. lPreferably this shoe or apron consists of an upper portion of metal and a lower rearwardly-projecting por- Y tion 830i leather, upon which the dirt thrown forward by the brush 7 -is initially received. Within the box' or casing 3 are mounted the drums 18 19, aboutwhich extends the endless bucket conveyer 20. This consists, preferably, of a band of cloth having aseries of transversely-extending wooden strips 80, provided with projecting metal plates 81, secured thereto. The plates 81'protect the wooden strips from wear and form sides to retain the dirt along that run of the conveyer which moves upward. The lower end of the box or casing 3 is curved and so shaped as to fgartially surround the lower drum 19 of. the conveyer, as lindicated at 21, and to the rear edge of this portion 21 is hinged the abovedescribed apron 22. The conveyer is driven from the sprocket-wheel 6, mounted on the rear axle of the machine. A chain 26 con- ,nects said sprocket with a sprocket 25, mounted on one end of a shaft journaled in suitable bearings on the main frame 1. 0n the same shaft with the sprocket 25 is secured a similar sprocket 24, which is'connected, by means of asprocket-chain 27,with a driving-sprocket 23, mounted on the .shaft 44 of the upper drum or roller 13 of the' conveyor. An idlersprocket 28 is suitably secured to the conveyer-'casing and arranged to engage with the chain 27 to take up any sag that would otherwise occur therein.

4 designates the dirt receiver or receptacle, which ,is mounted upon the main frame in such manner as when in operative position to extend below the forwardly-projecting hood 29 of the conveyer-casing. Said receptacle is preferably open at the and, sc 'that material carried upwardly bythe endless conveyer and discharged 4over the drumA 18 will be received therein. .The receptacle 4 is mounted upon a vertical pivot or rotatable support 30 at one side of the machine, and when a suflicient quantity of dirt has accumulated therein said receptacle is swung about said pivot to cause its body to project beyond'the side of the machine, as indicated in Fig. 1, and the contents thereof can then be discharged onto any desired surface or into a wagon. v Preferably the bottom of this dirtreceptacle is composed of a series of removable plates 31, each being provided at one end with asuitable handle 36. As shown, the

side walls of the receptacle 4 are inclined inwardly near the bottom thereof, and a supporting-bar 32 is secured below the lower f edge of one of said sides, it being preferably connected to said side, but held at a distance therefrom equal to the thickness'of the bottom plates 3l, by means of a' series of pins or bolts 33. To the opposite wall of le rethe notch N thereof the forward end of said plate to be lifted ver- `one side of the machine,

ceptacle 4 are secured series o f hook-shaped hangers, which are arranged 1n substantial alinement with the pins or bolts 33. Each of the removable bottom plates is provided in its edge adjacent tothe handle 36 with a notch N vand in its opposite end or edge with a similar notch O. To place either of the removable plates in position, the notch O thereof is placed in alinement with one of the pm s 33 and the plate is pushed rearwardly unt1l al'ines with and permits tically past the hook 35. Then by a slight forward movement he body of said hook is brought into the notch N, and the plate 31 1s supported by the -strip 32 and hook 35.A

37 designates aninclined bar or strut which is adj ustably secured to the frontof the frame of the machine and adapted to engage with the ground to preventxthe machine from being tipped when the loaded dirt-receptacle is moved into position to discharge its load at as shown in Fig. 1.

When in 'position to be loaded, the receptacle 4 is engaged by a bar 38, which is pivotally connected at one end P with the side wall of the conveyor-casing and at its opposite end is connected, by means of a link 41, with an operating-lever 40. A lug or stop 39 is secured to said bartand is adapted to engage with the forward inclined side wall of the receptacle 4 when the same is in position to be loaded. When it is desired to discharge the contents of the receptacle 4, it will be understood that the locking or retaining bar 38 is first moved into the position shown in Fig. 1 and in dotted lines in Fig. 5.

It will be seen that by mounting the refusereceptacle upon a vertical pivot or axis adja` cent to one side of the machine the operator is enabled to readily swing the same into a position where it will project to any desired extent beyond the side of the main carryingframe, and it is unnecessary to lift the weight of the refuse material when moving the receptacle therefor into position to discharge its contents.' By our construction also the 'operator is enabled to easily regulate and control the escape of material from the refusereceptaclethatA is,i by withdrawing one or more of the removable bottom boards the size of the discharge-opening is varied. The entire weight of the material is not brought against any one of the bottom pieces, but is ICO I'I O distributed equally over Vthe entire series,

whereby any one may be easily withdrawn and the point of discharge varied according to the wishes of the operator. A l

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination with a wheeled supporting-frame, of a receptacle'mounted at one end upon a pivot at one side of the supporting-frame, whereby it can be swung transversely outside of its frame, and having a discharge-opening in its bottom.

thereof to discharge its contents, and a bar or strut connected with the frame and adapted to engage with ground at that side of the machine beyond which the receptacle is pro- .jected to discharge its load.

5. The combination of a wheeled supporting-frame, a horizontally-adj ustable receptacle mounted on the frame and adapted to be projected beyond a side of the machine to discharge its contents, and a series of removable bottom plates for said receptacle.

In testimony whereof we hereunto set our hands this ltll day of December, A.

2. The combination with a frame, and supporting Wheels therefor, of a receptacle mounted at one extremity upon a vertical pivot at one side of the machine, whereby it can be swung to one side thereof, and having a removable bottom.

3. The combination with a wheeled supporting frame, of a receptacle extending transversely across said at one end upon a vertical pivot situated at one side of the frame, a locking device for holding said receptacle in position to be loaded, and a removable bottom adapted to close the lower end of TON H.
