SANITARY RECEPTACLE.

Application filed March 29, 1924. Serial No. 702,762.

To all whom it may concern:

Be it known that I, ALBERT EDWARDS, a citizen of the United States, and a resident of Bridgeport, in the county of F airfield and State of Connecticut, have invented certain new and useful Improvements in Sanitary Receptacles, of which the following is a spe ification.

This invention relates to an improved sanitary receptacle, and has for an object to provide a receptacle of this character ada ted for use as a container for sugar, cant y, doctors and dentists supplies, tobacco, and other such articles, which it is del o a sired to malntaln in a clean and sanitary enclosure, free from dust, dirt and vermin, and which at the same time will be quickly and conveniently accessible.

To this end it is proposed to provide, in the present embodiment of the invention, a receptacle having a counter-balanced cover adapted to be conveniently moved to open position, and which will automatically return to closed position, without effort or volition on the part of the user.

A further object is to provide a recepta' ole of extremely simple construction, attrac tive in appearance, and which is'free of any structure or parts that can readily get out of order. Other objects are to provide an improved means for attaching the cover to a one piece bowl, of glass, crockery, or the like, and further to provide a cover which may be readily fixed in open position, when desired, as during filling.

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment willbe hereinafter more fully described with reference thereto, and the inv vention will be finally pointed out in the claims.

In the drawings:

Fig. 1 is a front elevation of a sanitary receptacle, according to the present embodiment of the invention, and showing the cover in its normal closed position;

Fig. 2 is a side elevation of the same;

Fig. 3 is a vertical sectional view thereof;

Fig. 4 is a side elevation, showing the cover in fixed open position, and also indicating in dotted lines another open position, from which it is adapted to be returned to closed position;

Fig. 5 is a side elevation of a modified form of the invention Fig. 6'is a detail fragmentary view of the interlocking securing means for the cover supporting band employed;

Fig. 7 is a sectional view, taken along the line 77 of Fig. 6; and

Fig. 8 is a sectional view, taken along the line 88 of Fig. 6.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, the receptacle, according to the present embodiment of the invention, comprises a globular spherical bowl 10, open at its upper side, and having a flat base 11, and formed of any suitable material, depending upon the particular use to which it is to be put, as glass, porcelain, crockery, or'the like. At its lateral equatorial line, the bowl is provided with an impressed annular recess 12, within which there is disposed a substantially flush cover supporting metal band 13, the ends of which are connected by an interlocking flush joint, consisting of a tongue 14 at one end, having a reduced neck portion, and interlockingly engaged in a correspondingly shaped cut-out 15 in the other end, the side walls 16 of the neck being slightly beveled, as shown in Fig. 8, and the engaging walls of the cut-out being swedged or forced over into locking relation therewith. This construction provides a neat flush structure, and greatly facilitates and economizes assembling.

The band 13 is provided at diametrically opposite points with projecting pivot screws 17 and 18, riveted therein, and upon which the cover, presently to be described, is rotatably supported in a manner to be lowered into tight relation with the edgeof the bowl opening in the closed position, and to be raised slightly upon rotation in either direction to permit of the free movement of the cover about the sides of the bowl.

The cover comprises a top 19 in the form of .a concavoconvex spherical segment, of

greater diameter than'the bowl, and adapted to cover the opening with its edges proeoted slightly below the edge of the opening. the inner surface of the cover, in the closed position thereof, resting upon theedge of the opening of the bowl, so as to render it airtight and dust-proof. At each side of the top there are provided downwardly extendingside arms 20 and 21, in continuation of the spherical curvature of the top, and

disposed in slightly spaced relation to the upper hemisphere of the bowl, and depending below the band 13 in diverging relation to the lower hemi-sphere; being provided with substantially pear-shaped apertures 22 in alignment with the pivot screws 17 and 18. Pear-shaped flanged camming pivots 23 are secured upon the respective pivot screws, being fixed against rotation by soldering or the like, and are engaged by the apertures 22 of the side arms, the resiliency of the arms and the flanges of the pivots retaining the arms in place, and at the same time permitting the cover to be readily disengaged, when desired for cleaning, or the like, the apertures being of such size as to slip over the flanges. In the closed position of the cover the points of the apertures 22 engage the points of the pivots 23, so that the cover is lowered and engaged tightly upon the edge of the opening of the bowl. Upon swinging movement of the cover to either side the camming pivots cause the cover to be immediately lifted, so that its inner surface is free from the surface of the bowl, and it may therefor be freely swung to open position. As is clear from the drawings the sides of the camming pivots diverge gradually at each side of the point and merge into the lower semi-circular cross section portion; the apertures being of greater height and width than the pivots, and the width being just slightly greater than the height of the pivots. Upon rotation of the cover the inclined side of the aperture rides over the point of the pivot, camming the cover to slightly raised position, and in which position the inner surface of the cover is concentric to and slightly spaced from the globular surface of the bowl. In the completely open position, as shown in full lines in Fig. 4, the aperture is at right angles to the camming pivot, and the vertically disposed pointand base of the pivot is snugly engaged by the transverse portion of the aperture so that looseness is prevented, and the cover may be at the same time freely rotated. Upon closing the cover lowers into engagement with the edge of the opening, the frictional engagement upon coming to such closed position preventing swinging of the cover.

At their lower ends the arms are apertured, as at 24-, and have ball weights supported thereon, these weights each comprising hemi- spheres 25 and 26 secured at each side of the arms by means of a screw 2'? in one of the halves engaged through the aperture 24 in a threaded socket 28 of the other. These weights may be of any suitable con struction, and attached in any suitable manner, as will be obvious.

The cover is provided centrally with a handle 29 screwed thereon by means of a threaded shank 80, secured against removal by peening over the inner end of the ,shank,

as at 31. Sufficient clearance is provided between the cover and the handle to allow the latter to be screwed inwardly, as shown in F 41-, to engage the end of the shank against the band 13, to thereby secure the cover in open position.

The weights being heavier than the cover and disposed below the center of gravity, normally counter-balance and center the cover to maintain it in closed position, it being only necessary, in order to obtain access to the bowl, to swing the cover to either side, as shown for instance in dotted lines in Fig. 4-, the weights automatically returning the same to closed position upon release.

In Fig. 5 I have illustrated a modified form of pivotal mounting for the cover consisting of a circular cross-section pin 32 secured to the band 13, and having a vertically disposed flattened head 33 projecting above and below it, the pin being adapted to be engaged by an aperture 3 1- in the side arm of the cover having horizontally extended slot portions 35 adapted to pass over the head 33, in the lateral open position of the cover, being locked in pivotal relation upon the pin in all other positions. Inasmuch as the arms of the cover are slightly resilient, this feature permits the cover to be readily removed, when desired, and greatly facilitates the assembling of the device.

I have illustrated and described preferred and satisfactory embodiments of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent 1s:
