Original application August 28, 1935, Serial No. 38,176. Divided and this application January 23, 1936, Serial No. 60,441

4 Claims.

The invention relates in general to metallic receptacles such as open top and bottom containers for garbage and other waste cans and particularly relates to the mechanism for actuating the closures of such containers and specifically relates to the combined hinge strap and actuating lever journalled on the bead wire at the top of the container.

The present application constitutes a division of my copending application entitled Garbage and waste cans, Serial No. 38,176 filed August 28,

The primary object of the invention is to provide an improved form of receptacle of the type outlined and particularly to provide an improved and simplified mechanism for lifting and lowering the top closure and associated parts.

Various other objects and advantages of the invention will be in part obvious from. an inspection of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of the device embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

Fig. 1 is a view in side elevation of a garbage can illustrating a preferred embodiment of the invention Fig. 2 is a detailed View of the pedals at the lower right side of Fig. 1;

Fig. 3 is a detailed plan view of the hinge connection at the upper left side of Fig. 1; and

Fig. 4 is a modified form of the hinge strap.

Referring to the drawing there is disclosed a receptacle H1 in the instant case showing the open bottom can or container for receiving the usual garbage can (not shown).

The lower edge H of the upstanding cylindrical wall I2 is bent back upon itself to form an edge reinforcement bead The outer side 14 of the bead I3 is cut away to provide a plurality, one for each leg, of pairs of openings i5 and it.

This forms a series of long beads ll between the short, hollow, tubular beads i8 defining the inner ends of the openings I5 and 56.

by being clamped within the long beads.

These legs are connected by the length of wire therebe- V tween forming the combined tie and bead wire 26.

The receptacle I0 is provided at its upper end with a hinged closure 21. The upper edge of the receptacle i0 is bent back upon itself to form a head 28 and in this bead is contained an endless bead wire 29. The bead is interrupted at the rear portion of the can to form an opening 30 with a portion of the wire 29 bridged across the opening and forming a hinge pin located slightly exteriorly of the adjacent side of the receptacle. Secured to the cover 21 is a length of rigid material forming a combined actuating lever and hinge strap 32. The strap is provided with two parallel slits 33 and 34 with the portion of the material between the slits bent in one direction out of the plane of the remaining portion of the plate to form one side of a transversely extending hinge eye 35 and the material to the outside of the two slits is bent in the opposite direction, out of the general plane of the slits and into a groove, to complete the formation of the eye so that there is provided a relatively long hinge connection between the closure and the body of the receptacle. To one side of the hinge connection, the plate is provided with a plurality of apertures 38 by means of which it is riveted or otherwise secured to the underside of the closure 27. The portion of the plate to the opposite side, that is outwardly of the hinge connection, forms a rearwardly extending lever 31 having its outer end upturned and provided with a transversely elongated slot 33.

Directly below the lever 31 is located the upstanding lever arm 39 of a rocking shaft 4B which extends diametrically beneath the receptacle iii. The shaft 40 is journalled adjacent its opposite ends in supplemental legs 4| and 42 which function additionally to provide two supports for the receptacle [0 in addition to the legs l9 and these two legs are disposed to transmit to the ground, floor, or other support, strains which may be imposed thereon by the operator in the act of lifting or closing the closure 21. In the illustrated instance the legs 40 and 42 are formed at the ends of a bent strip of flat material having inturned feet 43 and secured at their upper portions to the wall l2 in the region reinforced by the lower bead and its associated bead wire. The lever 39 terminates in a hooked end 44 and a rigid reach rod 45 extends between and is pivotally connected at its opposite end with the levers 3i and 39. It is herein suggested that the upper ends of the legs 4! and 42 be connected by the strap 48 which tends to reinforce the open bottom of the receptacle.

The forward end of the shaft 40 is provided with two transversely extending pedals 46 and 41 forming foot actuated levers projecting from opposite sides of the shaft, normally disposed as shown in Fig. 2 in a horizontal position and disposed so that the shaft 40 is rotated to elevate the closure 2'! whenever the operator steps indifferently on either pedal 46 or 41.

In place of the form of hinge strap shown in Fig. 3, it is suggested that the eye encircling the V hinge pin 3| be formed of two parts, as shown in Fig. 4, and without the slits 33 and 34. One part 32 corresponds to the strip bent into a transversely extending groove to form the overlapping portion of the eye as shown in side elevation in Fig. 1 and the underside of the eye formed of a thin flat rectangular strip of metal 49 bridging across the groove and Welded along opposite edges 50 and 5! to the portion of the plate 32 on opposite sides of the groove.

By means of the eye form of connections shown in both Figs. 3 and 4, it is possible in the act of mounting the upper bead wire 29 in place to string the hinge leaf 32 on to the bead wire before the upper bead is bent into place and in this way the strap is restrained from falling off the wire during the fabrication of the can.

In operation and assuming that the operator has stepped on the right hand pedal 4'! to lower it from the elevated into the dotted line position shown in Fig. 2, the shaft 40 will be rotated over a small angle in a clockwise direction which similarly rotates lever 39 and this lever lowering the reach rod 49 will move the closure 21 from its closed into an elevated open position and in which position the closure has a tendency to remain .due to the fact that when elevated the center of mass of the cover is slightly outside of the vertical plane containing the axis of rotation of the closure. As the right hand pedal 41 is lowered, it will be noted that the left hand pedal 46 will be elevated. It is then simply required that the operator step on whatever may be the elevated pedal, in this instance the pedal 46, to rerotate the shaft in an anticlockwise direction and thus positively lower the closure 2'! into its closed position. The fact that the closure may be moved from its open position, past its position above its axis, is due perhaps to the outward or upward bent of the lever 31 which resolves the upward thrust of the rod 45 into an outwardly directed component to rotate the lever.

While there have been shown, described, and pointed out in the annexed claims, certain novel features of the invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
