Device for the dust-free discharge of circular dustbins into refuse-collecting carts

Application filed February 17, 1928, Serial j

My invention relates to a device for the dustfree discharge of circular dustbins with hinged covers into refuse collecting receptacles or carts and is an improvement on the 5 pending application Serial No. .76091, filed December 17,1925. _ : '

My- invention consists substantially in adapting a rocking or oscillating member provided with the charge .opening on pivots be10. tween the sidewalls* of the hood sealing the cart, in such a manner that when the bin is being tipped into the cart said rocking member swings inwards with one end and outwards with the other end. The handling of 15 the bin during the tipping is greatly facilitated in this way, inasmuch as part of the weight only of the dustbin need be lifted. Preferably the arrangement is such, that the said rocking member is not directly carried back 20 into the initial position by the cover or lid, but that the rocking member is coupled with the dustbin by means of suitable coupling members in such a manner, that the lid of the dustbin and the hinge of the lid are relieved 25 _of all strains. This coupling of the dustbin and the rocking member may be effected in such a manner that a coupling member of the rocking member engages a coupling member provided on the shell of the bin when the 30 bin is being tipped into the cart, or that on the frame serving for the reception of the dustbin coupling members aivy provided, which are adapted to be displaced by a rotary or rectilinear motion, which are controlled 35 by springs and on the other hand are guided by suitable cam surfaces -when the rocker is operated.

In the drawing affixed hereto and forming part of my specification an embodiment of my 40 invention is illustrated by way of example.

In the drawing is: .

Fig. 1 a cross-section through the hood of the cart with the dustbin placed in position for tipping.

Fig. 2 a similar cross-section with the dtist. bin in the tipping position, and

Fig. 3 a front elevation of my improved device. Like parts are indicated by like letters of reference throughout all the figures of the. 50 drawing.

Referring to the drawing it will be seen that the rocker a is adapted to swing between the sidewalls i of the hood upon pivot pins b. The rocker a is composed of the side portions

x, the top part s, the lower enclosing member 55 t, and the transverse plate z. The enclosing plates s and t extend right across the .width of the rocker and are joined to the side plates x. The bottom cover t encloses a chute w also extending right across the width of the 60 rocker. A cover or lid e hinged at c-closes the charge opening d in the rocker a. The rigid arms g mounted on the cover e carry in. hinge joints f the connecting, links h, h¹. These connecting links 7t, 7A are adapted to 65 rotate upon a rod r extending between the side Avails i of the hood. A rod or spindle y¹ extending across the entire width of the rocker is adapted to turn in bearings y upon the, curved top s of the rocker. At the ends 70 of the spindle y¹ are provided fingers k and in the center the coupling hook 1. The fingers k and the hook I are controlled by a helical spring wound around the spindle y¹. For operating the fingers ,¾ against the resistance 75 of the .spring stops m are provided upon the sidewalls i. On the shell n of the dustbin is mounted a coupling member o adapted to cooperate with the coupling hook 7 on the rocker. A packing frame p enclosing the 80 rocker a seals the rocker dustproof against the outside.

The improved device operates in the following manner: the dustbin is in. the usual way hung up on the hooks u of the rocker a 85 by’means of the suspension rod v mounted upon it and tipped up. A hook on the lid of the bin then engages a pocket or recess in the cover o closing the charge opening. During the further progress of the tipping operation 90 the ring enclosing the mouth, of the bin comes in contact with the edge of the charge opening d and forces the part of the rocker a above the pivot inwards while the lower part of the rocker is simultaneously pulled outwards 95 by the suspension rod v and the hooks u. The fingers k then slide off the stops m and disengage the coupling hooks 1 controlled by the helical spring and these hooks come in engagement with the coupling members pro- 100 vided upon the shell of the bin. While this takes place the joint f with the connecting links Λ are swung upwards and the lid of the bin hooked into the cover e of. the charge opening is opened. When the bin is with.- 105 drawn it forces by means of the ring around its mouth the outward swung portion of the rocker inwards, while simultaneously the bin

1,715,364 coupled with the rocker by means of the coupling members ο, Z pulls the inwardly swung part of the rocker outwards so that thus the closing motion takes place without subject5 irig the lid and the hinge , of the bin to any strains, on the one hand by the dust-bin pressing upon the outwardly swung portion of the rocker, and on the other hand by the action of the coupling members ο, I.

Various changes and modifications may be made in the details of construction without departing from the spirit of my invention.
