Application June so, 1947, Serial No. 758,061

Our invention refers to securing means for can tops or covers. v

The object of our invention is to provide a pair ,of spring controlled latches for firmly seating and tightening the slip cover of any standard can, whereby the same is held to its seat against blasts of wind, or in the event the can inadvertently is knocked over.

It is understood that the set of latches may be readily attached to any standard cans in use, or the same may be attached as a part of the equipment in the manufacture of new cans.

The device thus overcomes unsanitary conditions due to spilling or scattering garbage from an open can, and cans so equipped are practically sealed to prevent the entrance of flies or other insects that would quickly develop germs or the like, or cause odors from the garbage so stored.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a side elevation view of an ash can having cover securing means embodying the features of our invention.

Figure 2 is a fragmentary enlarged sectional view of one corner of the can and top, illustratin the latch connection, the section being indicated by the line 2-2 of Figure 3.

Figure 3 is a plan view of the same.

Figure 4 is a front elevation of the latch mechanism, in conjunction with fragments of the can and top.

Figure 5 is a sectional plan view through the can, illustrating certain of the latch details, the section being indicated by line 5-5 of Figure 2.

Figure 6 is a detailed plan view of an offset arrangement between the bracket and ear.

Referring by characters to the drawings, A indicates an ash can, and B the slip cover thereof, it being understood that any type of can and cover may be employed in connection with our latch mechanism.

A pair of ears 2 are secured to the periphery 1 Claim. (01. 220-55) of the can top B by pointed sheet metal screws ,2. These screws are used to facilitate the assemblage of the latch mechanism upon ash cans now in use, and said screws due to their pointed ends, can readily be fastened without the aid of drilling or the like, but can be punctured.

The outer ends of the ears project beyond the edges peripheral of the slip cover, and they are provided with end apertures 2".

Directly below the mouth of the ash can we similarly attach, by metal screw, an angle iron bracket 3, having ofiset arms 3 apertured at their ends, the said arms and ears being in parallel relations.

Reciprocally mounted in the arm apertures, are rods 4 having at their upper ends hook extensions 4', which extensions terminatewith depending noses 4" adapted to engage the apertures 2 of the ears.

The lower ends of the rods 4 have mounted thereon washers locked by keys 5, andwashers 5' are loosely mounted upon the rods directly under the faces of the arms. Interposed between the washers 5 and the key locked washers at the ends of the rods, springs 6 are loosely mounted upon said rods, whereby they exert a downward pull upon the same. This downward pull of the rods is checked by keyed washers 5", which engage the upper surfaces of the arms 3.

From the foregoing description it is apparent, when the latch mechanism is in the position shown in Figure 2 of the drawings, the cover is firmly looked over the mouth of the can.

Should it be desired to remove the cover from its locked position, it is only necessary to lift the pair of hooked rods to the position indicated in dotted lines Figure 2.

Figure 6 illustrates a slight change of the position between the bracket 3 and ear 2, whereby the rod 4 is arranged to lock the cover B tangentially, said arrangement being for the purpose of more readily adjusting the clip member.

Thereafter, the hooked rods are swung outwardly, as indicated in dotted lines Figure 2, whereby the cover is entirely freed from the latch mechanism, and it can then readily be removed.

It follows in order to close the cover it is only necessary to insert the same over the mouth of the can and swing the locking rods to the position shown in Figure 2, whereby the nosed ends 4' of said rods are socketed snugly within the apertures of the ears 2, whereby the springs 6 will exert a downward pressure upon the cover to prevent its inadvertent removal.

It should be noted that the apertured ears 2 project beyond the periphery of the cover and hence when said cover is slipped over the mouth of the can the projecting tongues serve as handles, whereby they are utilized to rotate the cover in a position of alignment with the nose portion of the spring controlled rods, whereby said rods are manipulated for locking engagement. In other words, the tongues serve two purposes for convenience in operation of the device. 7

It should also be noted that in assembling the latch mechanism, it can be done with a set of meta-1 screws without leaving any gpenings in the cover, which would otherwise result 'in p"er'-- ery thereof, the outer end of said ear having a keeper opening, a bracket rigidly's'ecilfedto the sidewall of the an having a fadiallyprojectin'fg arm provided with a guide opening, Sal d a'lifm extending beyond 'theear, a latch rod slidably prim, mi s -n lly iib in rifle latch nose in a lowered ear engaging position.
