I REFUSE COLLECTING VEHICLE Filed Sept. 19, 1956 2 Sheets-Sheet 2 United States Patent REFUSE CDLLECTING VEHICLE Hilding Linde, Kalmar, Sweden Application September 19, 1956, Serial No. 610,779
3 Claims. (Cl. 214-302) The invention relates to a refuse collecting vehicle with a collecting container and an emptying plate having an opening to be engaged by the mouth of a dustbin and being pivoted at its lower edge on the top portion of the container for the discharge of the dustbin into the container. If no feeding screw or other compressing device for the collected refuse is used, a difficulty appears to distribute the load throughout the container, especially if the refuse is discharged into the same portion of the container.
An object of the invention is to provide a distributing device of a simple and effective construction consisting of a few movable parts.
Another object of the invention is to provide a simple driving mechanism for moving the distributing member along a straight path, which driving device is well protected from contact with the load.
These and other objectsv and advantages will appear hereinafter, reference being made to the accompanying drawing in which:
Figure 1 is a rear end elevation of a refuse collecting vehicle according to one form of the invention,
Figure 2 is a side elevation view of the upper portion of the vehicle,
Figure 3 is a longitudinal sectional view showing the distributing device, and
Figure 4 is a top view of the distributing member.
A collecting container 1 is at the top portion provided with an emptying hood 2 for dustless emptying of dustbins. Within the rear end of the hood an emptying plate 6 having an opening for the mouth of the dustbin is pivoted at its lower edge around a shaft 7, and the plate together with the dustbin can be swung inwards to the discharge position shown with dash and dot lines in Figure 3. The dustbin is placed on a carrier 4 which is movable in guides 3 and can be hoisted up by means of lift cables in a known manner.
Two parallel driving arms 8 are at their upper ends pivoted around a shaft 9 one on each side of the emptying plate within the hood. The lower end of each arm 8 is at 10 pivotedly connected with a link 11, the other end of which is pivotedly connected at 12 with a supporting arm 13 for a rake 14. The rake is formed of an extended metal plate bent to an obtuse angle to a form like a plough.
The rake is at some distance from its ends provided with two parallel forwards directed bearing plates 15 connected by a welded upper stop plate 16. The supporting arm 13 is tted between the bearing plates 15 and is connected thereto by means of a pivot pin 17. The supporting arms have an horizontal upper portion provided with two rollers 18 running in two horizontal guide rails 19 with a U-formed section and provided immediately below the roof of the collecting container. As appears in the drawing the rear ends of the supporting arms are turned downwards to the bearing plates 15. Within the hood and at each side thereof a hydraulic piston motor 20 has its cylinder end pivoted at 21 in a U-shaped support 22, whereas the piston has a fork-shaped member 23 pivotedly connected with the driving arm 8.
When a dustbin has been discharged in front of the rake, and if the load reaches to a level above the lower portion of the rake, the both pistons which are operated by means of pressure oil swing the driving arms 8 from the position shown by full lines to a position indicated by dash and dot lines. The rake 14 is thereby moved forwards along a straight path and is maintained in the shown vertical position by means of the stop plate 16 which bears against the vertical portion of the supporting arm 13 so as to prevent the rake from turning around the pivot 17. The upper layer of the load is moved by the rake forwards, and owing to the angle shape of the rake the load is also distributed towards the sides of the collecting container. It is obvious that the load previously accumulated by the rake will be further displaced forwards at the end of the forward stroke and that the fore portion of the container can be lilled up in this way, although the path of the rake is essentially shorter than the length of the container.
At the return stroke the rake has the possibility to swing around the pivot 17 and slideover the upper surface of the load without conveying anything thereof backwards.
By the shown distributing device the volumetric eciency of the container has been considerably increased. The driving mechanism of the rake is mainly located within the hood above the roof of the collecting container, whereby it is well protected and easily available for inspection. The structure above the roof of the container may be rather low which is of advantage with respect to the garage.
I claim:
l. In a refuse collecting vehicle, a collecting container, a carrier to be easily connected with a dustbin, a hoisting device for raising the carrier with the dustbin and tilting said dustbin, an emptying plate having an opening to be engaged by the mouth of the dustbin and being pivoted at its lower edge on the top portion of the container for the discharge of the container, two parallel guide rails located within the container in the upper portion thereof, two supporting arms movable along said guide rails and guided at at least two points, a transversely extending refuse distributing rake pivoted in said supporting arms so as to allow the rake to swing upward during the return stroke but provided with a stop member resting against said supporting arms during the feed stroke, two parallel driving arms passing through the top portion of the container and being pivoted at their upper ends above the container, two links connecting the lower ends of said driving arms and the movable rake system, and a power source located outside the container for rocking said driving arms.
2. A refuse collecting vehicle as defined in claim 1, wherein each of said supporting arms are provided with at least two rollers, a guide rail, said rollers running in said guide rail, and a downwardly extending portion connected with said rake, and that the links being connected with said downwardly extending portions.
3. A refuse collecting vehicle as defined in claim 1, wherein the end portions of the rake form an obtuse angle to each other.
