To aZZ whom it may concern.- 3. The front end of the casing is supported Be it known that I, ERASTUS L. HAWKS, a by a swiveling-truck l, to which the draftcitizen of the United States, residing at Dayanimals may be attached in anysuitable manton, in the county of Montgomery and State ner.

Fig. i is a transverse vertical From the foregoing construction it will be sectional elevation on the line 4 i of Fig. 2. seen that the inner edges of the two bottom Referring to the drawings,the machine complates are suspended by links from the horiprises a rectangular casing or frame 1, coin zontal rod, the slotted upper ends of the links 45 structed preferably of sheet metal and closed permitting a limited vertical movement of the on'all sides except at its rear, where the botplates. The purpose of this is to admit of tom is open to permit the brush, hereinafter the passage of the machine over stones or other referred to, to act on the surface of the ground. obstructing matters without causing injuries An axle 2 is mounted in bearings on the sides to the bottom of the receptacle. Near their loo 0 of the casing near its rear end, and on the ends outer edges at opposite ends the bottom plates of the axle are journaled two ground-wheels are each provided with a bracket 18 bolted or .ferred to.
otherwise firmly secured to the upper side or" the plate, and to each bracket is pivoted the lower end of vertical link 19, which link extends upward through the top of the casing, where they are pivoted at their upper ends to the outer ends of four arms 20, 21, 22, and These arms are arranged two at e'ach side of the machine, and at their inner ends the rear arms, 22 and 23, are provided with studs 24, mounted in bearings 25 on the upper endsof brackets or standards 26, rising from. the top of the casing at opposite sides of the same. Beyond the bearings the arms are provided with segment-racks 27 which engagesimilar racks 28 on the ends of the forward arms, 20 and 21, which latter are fixed to the opposite ends of a horizontal rock-shaft 29 mounted in bearings 30 on the two standards before rewardly-extending operating-lever 31 fixed thereto, by means of which the shaft maybe rocked, which action will rock the two forward arms in vertical planes, and the racks on their inner ends engaging the racks on their rear arms, the four links connected to the arms will be moved up and down vertically, and in this way will elevate or depress the outer edges of the bottom plates to open orclose the bottom of the receptacle.
In order that when the outer edges of the plates are raised they will move in truly vertical lines for the purpose of causing the separation of the inner edges to allow the contents of the receptacle to pass to the ground, I provide four fixed vertical guide-rods 32, one at each corner of the receptacle adjacent to the brackets on the bottom plates, and to each of the brackets I pivot on a horizontal transverse axis a vertical sleeve or collar 33, which sleeves encircle 'and slide upon the guide-rods, As a result of this arrangement, when the links connected to the outer edges of the bottom plates are raised the brackets to which they are pivoted will be caused to move in a truly vertical direction on the guide-rods, and as the edges of thetwo plates are carried upward the plateswill assume inclined positions, as indicated in Fig. 3, their inner edges at the same time separating with a swinging movement on the upper ends of the suspending-links 14 as an axis. The inclination of the plates will cause the contents of thereceptaCle to quickly fall to the ground, and a quick vibrating movement being given to the operating-lever the plates will be correspondingly vibrated or shaken and any adhering dirt or matters will be loosened. On the release of the lever the weight of the plates will cause them and their connections to resume their former positions, closing the bottom of the receptacle.
To prevent the escape of any matters between the receptacle and the brush, I provide an intermediate apron 34 in the form of a rectangular metal plate, the rear edge of which is arranged beneath the brush, from which point the apron extends forward and This shaft is provided with a rear upward at a slight inclination to the rear bottom plate, 13, to the edge of which the apron is pivoted on a horizontal transverse dump the contents of the receptacle, so that any dirt or other matters on the apron will be caused to pass to the ground. Owing to this connection of the apron with the plate the shaking or vibrating of the former will cause a corresponding shaking of the apron, which will serve to effectually loosen any adhering mud or dirt. The rear edge of the apron is sustained at its opposite ends on two inwardly-extending flanges 37, project'- ing from the lower edges of two guards or shields 38, located at the sides of the casing at the outer ends of the brush. These guards are formed so that they extend in the path of the brush and compress its active face and also close the space between the ends of the brush and the casing, thereby preventing any dirt from escapingaround the brush to the outside. These guards may be fixed to the sides of the casing or sustained in any other suitable manner, but in the present instance I have shown them as being suspended by links 40 from the two crank-arms connected to a horizontal rock-shaft 41.
As the guards and their connections constitute no part of the present invention, it is suflicient to refer to them incidentally only as to their function in giving support to the rear edge of the apron.
To provide for access to the interior of the receptacle from the side, I construct one side of the same in the form of a door 42, consisting of two hinged members, one of which is connected to the side of the casing at its front on a vertical axis. \Vhen the receptacle is to be closedthe two members of the door are extended in line at the side of the same, in which position they may be locked by any suitable means. \Vh'en the receptacle is to be opened, in order to gain access to its interior for the purpose of repairs or for other purposes the doors are swung outward on their vertical axes and folded one upon the other, as shown in Fig. 1.
Having thus described my invention, 1 claimf- 1.
