Unit
This invention relates to a coupling device for connection of a dustbin and a collecting container and is especially useful for loading wagons, trucks and similar conveyances. As coupling members for the dustbin and the collecting container are heretofore usually used two hOOks and two bow-shaped handles, but it has been found difficult to bring about a safe engagement of the two pairs of coupling members located at a distance from each other, especially when a man is carrying the dustbin on his back and is unable to see the coupling members. If only one pair should obtain a proper engagement several disadvantages might be involved.
The main object of the invention is to remove such disadvantages and to secure a safe engagement of the coupling members.
Another object of the invention is to obtain an automatic adjustment of the position of the coupling member of the dustbin relative to the coupling member of the collecting container before their engagement.
With this and other objects in view the invention will be hereinafter described and is illustrated by way of an example in the accompanying drawing in which:
Figure 1 is a perspective view of a dustbin with a coupling member according to the invention, and Figure 2 is a front view of a dnstfree emptying hood with a corresponding coupling member. Figure 3 is a vertical sectional view of a portion of the collecting container and a dustbin in discharge position. Figure 4 is a horizontal partial sectional view on lines IV-IV in Fig. 2 and Fig. 5 is a corresponding elevation view.
In the drawing 1 is the side wall of the dustbin, 2 is a bottom flange, 3 is the handles, and 4 a hinged cover provided with a bow 5 for the opening of the cover by means of a corresponding hook 119 in the emptying device. Secured to the upper edge of the side wall is a reinforcement ring 6 of angle-iron with one flange sloping outwards. Below this ring a coupling hook 7 is fastened to the bin. It comprises a substantially plane portion 8 which at the ends is bent at a right angle to form sides 9 with bent portions Till resting against and fastened to the side wall 1. The plane portion 8 may narrow down to a point resting against the side wall. The portion forming the hook is bent to the form of a channel with a downwardly directed, substantially plane tongue 11 ending in a point 12 from which the side edges of the tongue extend obliquely upwards to an upwardly bent side flange 13 integral with the side portions 9. The side flange 13 serves to reinforce the tongue, and it is preferably welded to the angle iron ring 6. Thus the tongue 11 and the plane portion 8 form between them a channel for cooperation with a coupling member in the form of a rod on the emptying device. This channel has a suflicient length to keep the dustbin after having been hanged on the rod in the correct position even if the content of the bin would be excentrically loaded. Such a proper initial position of the bin is necessary for the completion of the coupling with the emptying device.
Figures 2 and 3 show the essential parts of the hood for dustfree emptying of the dustbin, and this hood may be mounted at the top of a collecting container 25. In a frame 14 an emptying plate 15 having an aperture corre sponding to the orifice of the bin is swingably mounted at its lower edge by means of a bolt with bearings 16. At the upper edge the plate 15 is hingedly connected by means of a bolt 22 to a plate 17 covering the orifice, and
States Patent 0 when the plate 15 together with the dustbin is swung inwards the covering plate 17, by means of a link or lever actuating mechanism 26, of the kind disclosed in U. S. Patent No. 2,163,844 and British Patent No. 376,523, is swung inwards and upwards to allow the refuse to fall down into the collecting container.
A coupling bow corresponding to the coupling hook 7 on the dustbin is secured on the emptying plate 15 and comprises a rod 23 connected at its ends with two supports 24 of sheet metal or a casting welded to the plate 1.5. The supports have an upper side surface 18 sloping towards the space or gap 27 between the rod and the plate 15. The distance between the supports and the free length of the rod is slightly greater than the channel in the coupling hook 7.
If hook 7 is to be introduced into the coupling bow and the point 12 of the tongue 11 should be located at the side of the middle of the yoke or rod 23 the edge 28 of the tongue will slide against the one support 24 which thereby guides the hook into the correct coupling position. Also in case the point 12 should strike the upper surface 13, it will slide upon it towards the bow whereafter the edge of the tongue slides against the support and the correct coupling is obtained as will appear from Figures 4 and 5.
The covering plate 17 is further provided with a hook 119 for engagement of the bow 5 on the cover of the bin and two handles 20, and the emptying plate 15 is provided with two guiding members 21 of angle iron with outstanding flanges serving to guide the mouth of the bin to the proper coupling position concentrically to the orifice of plate 15.
The shown form of the coupling member is to consider only as an example of the execution of the invention, and different modifications are therefore possible. The coupling hook must not necessarily be made of sheet metal but can also be formed of a metal rod bent in such a way that its middle portion is formed to a tongue and the ends of the rod are bent downwards and fastened to the dustbin so that the hook serves the object as the shown hood. Instead of providing the coupling member on the emptying plate of the emptying device it is also possible to combine the coupling member with a mechanical device for lifting and emptying the bin.
I claim:
Improvements in devices for collecting refuse, comprising an emptying plate pivotally mounted at its lower edge on a fixed portion of a collecting container, a first coupling member mounted on a carrier hingedly connected with the container for supporting a dustbin, and a dustbin adapted to engage an opening in said emptying plate for dustfree discharge and provided with a second coupling member for engaging said first coupling member and suspending the dustbin, said first coupling member comprising a rod between two end supports fastened to said carrier and having the upper surfaces inclined downwardly and towards a gap formed by the rod and the supports, and said second coupling member forming a single and wide coupling hook with the free end portion in the form of a tongue bent downwards and having its edges converging into a point so that the tongue when placed on one of said upper surfaces can slide thereon and into said gap.
