United States Pater REFUSE COLLECTING VEHICLE Hilding Linde, Kalmar, Sweden Application August 22, 1956, Serial No. 605,633
1 Claim. (Cl. 214-302) The invention relates to a refuse collecting vehicle of the type having a hoisting device for lifting a dustbin and discharge of its content into a collecting container. The hoisting device usually comprises a hydraulic jack connected with a carrier for the dustbin by means of wires. For the transport of the dustbins from the houses to the vehicle a cart may be used, from which the bin can be transferred directly to the carrier, for which purpose the carrier must occupy a low end position. If, however, the transport way includes steps or is otherwise so uneven that the cart cannot be used, the bin must be carried,l but it is di'icult for two men to carry the heavy dustbin by the handles between them up or down the steps. It would therefore be easier for them to carry the bin by means of a rod on their shoulders, but in such a case they have rst to lower the bin onto the ground and thereafter to lift it up again for placing it on the carrier, which is a trying work.
An object of the invention is to provide a refuse colI "Another object of the invention is to provide a simple' construction of a hoisting device which can be automatically stopped during the return motion at a desired intermediate level.
These and other objects and advantages will appear from the following dcription of the invention, reference being made to the accompanying drawing, in which:
Figure l is a side elevation of the rear portion of a refuse collecting vehicle with a hoisting device according to one form of the invention, and
Figure 2 is a corresponding top view.
On a chassis I1 a collecting container '2 is tiltably mounted on an axle 3 for the discharge of the container, and the rear wall 5 which is pivoted on an axle 4 forms the support of a hood I6 for dustless discharge of the dustbins. Two U-shaped rails form guides for a movable carrier 8 more clearly described in my U.S. patent specication No. 2,417,696. Two lift ropes 9 fastened to the carrier pass over guide rollers '110, 1-1, 12 and 13 and further over guide rollers 16 on the piston 15 of a single acting hydraulic jack 14. By means of an upper coupling hook the dustbin rests on the upper portion of the carrier, and when the carrier reaches its upper end position in the guide rails it can be swung upwards by means of the ropes around the upper pair of wheels embraced by the rails for the discharge of the dustbin, whereas the lower pair of wheels pass through corresponding openings in the flanges of the rails. The points in which the ropes 9 are connected with outwardly projecting arms of the carrier 8 are located in the plane defined by the pulleys 10, and these pulleys are mounted at such a level that said points pass above the pulleys.
In the drawing the dustbin and the movable part of the jack are shown with full lines in the desired interme-l diate position of the dustbin, which is indicated by dot Patented Sept. 15, 1959 and dash lines in its lower end position close to the ground and in its discharge position. Pressure oil to the jack is controlled by a valve with a handle 18 at the side of the hood. When the handle is switched over from its lower position to its upper position shown with dash lines, the dustbin and the carrier are lifted and swung" to the discharge position by a continuous motion without interruption, and when the handle is turned downwardsto its lower position, the dustbin and the carrier are continuously returned to the lower end position if not stopped in an intermediate position by means of a device described below.
On the roof of the collecting container a plate 19 is provided, in which a joint arm 20, 21 is pivoted. The arm 21 is normally maintained in the position shown by full lines by being pressed against a stud 29 by means of a spring 22 and carries on its end a roller 23 engaging a surface 24 of a transverse arm 25 provided with the guide rollers 16 and secured to the piston 15. On the return motion of the carrier the surface 24 strikes the roller 23 on the arm 21 for stopping the carrier in its' intermediate position. It should be noted that the arm\ 21 forms a right angle to the lsurface 24 and an acute angle to the moving direction of the piston. If it is desired to lower the carrier further to its end position, the arm 21 is swung outwards by means of the arm 20, a wire 26 connected to said arm and passing through a guide tube 27 downwards to the vicinity of the valve device l18, where the wire is provided with an operating handle 28.
The jack is, thus, easily released by a short pull in the wire 26. When the arm 2S passes from its left end position it automatically displaces the roller 23 out of the way against the action of the spring 22. The plate 19 may be adjustively connected with the roof for adjust-V ment of the intermediate position of the carrier.
By means of the arrangement described above the dust-l bin transported to the vehicle on a rod carried by two men can be easily coupled together with the carrier without any trying manual motions. It is obvious, however, that the form of the invention shown as an example can be modified without departing from the invention.
What I claim is:
In a refuse collecting vehicle, the combination with a collecting container of a carrier for a dustbin, guide rails provided on the vehicle for said carrier, a single acting hydraulic jack mounted upon the container wires connecting saidA jack with said carrier for hoisting it from a lower end position -to an upper end position and tilting the carrier from said upper end position together with the dustbin for discharge of the reliuse into the container, a transverse arm provided on the movable part of the hydraulic jack and having one end chamfered to form an inclined engaging surface, a spring-actuated stop arm pivoted at one end out of the path of said transverse arm and adapted to be swung to an active end position, in which its free end is located in the path of said engaging surface and the stop arm forms a substantially right angle to said surface for stopping the downward motion of the carrier in an intermediate position between its said end positions, and an operating arm connected with said stop arm for `swinging the stop arm out of engagement with said transverse arm.
