relate to covers which d removed from open- Tnese impl may readily be top receptacles f of while provi the cover inclu M -g a lnnged for gaining access t the container contents.

The objects are prima te provide a simple and advantageous cover i r cyllndric l containers. A specific ob ect is to provide simple and or holding the window element or" he lid securely in place when the device is in use while providing that a new window element may readily be substituted in case of breakage oi the old Other novel features are in the construction oi the body and of the combined hinge-and-rest unit. Other objects and advantages will appear hereinar ter.

1n the drawingrlligure l is a top plan of my improved cover; Fig. 2 is an enlarged medial normally-Vertical section through the device on the line 2-2 of Fig. 1; Fig. 3 is a still further enlarged but fragmentary vertical section following Fig. 2, but with the lid raised; Fig. 4 is an enlarged vertical section through the hinge on the line e-i of rlig. 1; Fig. 5 is a top view of the end portions or the window-holding frame; Fig. 6 is a perspective oi the combined hingeand-rest unit; and Fig. 'Y is a perspective detail of one of the ends or the window-holding frame.

The body le is formed oi thin sheet metal. It has an annular preferably substantially hat top l1 with an integral downwardly-extending ilange 12 beaded at 13 and adapted to t over the open top of the cylindrical receptacle 14 fragmentarily shown in Fig. 2. This top 1l will ordinarily be narrow so as to provide as substantially large an open interior for the ringlike body as reasonably possible, having due consideration for strength and appearance.

At the inner margin-s of the top il there is a downwardly-extending annular ange part 15 from which extends an inwardly-directed annular ilange part 16, the metal at 16 being turned back upon its-elin to provide a rounded edge at 17 whereby the users hand passing `into the ccntainer 14 will not be injured.

The cover body as thus described is preferably formed from a single piece of sheet material. With the outer and inner flanges as described the structure is appropriately strong and rigid. At 18 (Fig. 2) preferably form a rib-like upwardly-directed continuous projection which not only gives an attractive inish to the device but also strengthens it.

The inwardly-extending annular ange part 16 provides a seat for the lid marked as a whole 2c, and this seat is suiciently below the top 1i to bring the upper surface of the lid substantially flush with the upper surface oi the body part ll.

The lid 20 comprises a window element 2i wl'iich in practice will ordinarily be a piece o: ansparent glass cut to circular shape. Such glass windows become broken from time to time. In such case the device as a whole is ordinarily considered damaged beyond repair within the usual cost and convenience considerations, and is simply thrown away. One of the important objects of the present invention is to provide means for replacing such broken glass in a simple and easy way and at no further expense than having the local glass dealer cut out such a circular glass disc. This same feature facilitates the initial assembly of the device, and the glass may be removed from time to time for thorough cleaning of the several parts.

As to the lid construction, Fig. 1 shows a circular frame 22 which will ordinarily be continuous except for an interruption at one place. Fig. 7 shows that this frame 22 is substantially 'LJ-shaped in cross View providing an annular groove 23. It is formed by rolling thin sheet instal to the given shape. The end portions 22a are shown as being spread apart in Fig. 5. When so spread apart it is possible to insert the glass disc within the groove or recess 23 and thereupon when these end portions 22a are moved toward each other the ring 22 encompasses the edge portions of the transparent disc or window.

At each of these ends 22a 1 secure a metallic piece 26 as by soldering, each piece 26 having a hinge-lug 24 turned therein and having a leaflike part 25 which extends inward and rests upon the glass or window 21.

Fig. 6 shows a combined stop or rest and hingelug member. It is formed of thin sheet metal and has an upwardly-extending main part 28 and two end parts 29 bent substantially at right angles to the main part, the end parts having integral lugs 30 which project through elongated slot-like holes 31 in top 11 and are turned over or clinched at the bottom surface of top 21 to hold this unit strongly in place. From integral leaf-like extensions of the main part 2S a pair of hinge-lugs 32 are turned.

Note from Fig. 4 that the hinge-lugs 32 are spaced apart suiiiciently to admit between them the two hinge-lugs 24 carried by the ring or frame 22 when the ends of the ring-like frame 22 are holding the glass as shown in Figs. 2 and 8. When a hinge-pin 34 is inserted, as shown in Fig.

4, through all of the hinge-lugs the lid is not only hinged to the body but the ends of the lid frame are held in the position required for holding the glass disc in the recess of the frame. The hinge thus simultaneously provides a lock for the lid frame. By pulling out the hinge-pin 34, which may be an ordinary cotter pin, the lid comes away and its ends may be sprung apart to release the glass or to insert a new one.

Fig. 3 shows that the upstanding elongated main part 28 serves as a rest or stop to limit the opening movement of the lid, and that the leaflike parts 25 contact this rest part 28 and serve to protect the window from the eiects of an abutment by the window itself with such a stop element. The wing-like extensions 29 or" the stop device are bracing elements for ther main part 28 and they distribute the shocks of impact when the lid is carelessly thrown open.

A lifting handle 36 is secured to the ring-like frame 32 opposite the hinge. It is shown as a simple bail soldered to the frame.

A feature of advantage of the present construction is that the glass is held with a certain resiliency at its margins, the frame 22 being springy and yielding whereby shocks upon the glass are absorbed to amaterial extent. This springiness is increased by the resiliency in the annular seat for the frame at 16. Furthermore, since the lid L94as11 as a whole is substantially flush with the top of the cover many shocks otherwise coming upon the lid are avoided. The device as a Whole may be made according to manufacturing methods well understood, and at a very moderate cost.

I contemplate as being included in these improvements all such changes, variations and departures from what is thus specically illustrated and described as fall within the scope of the appended claim.

I claim:

In display-cover construction, the combination with a display cover body formed of thin sheet metal and having an annular top surface dening an open interior, with a depending flange at the outer margin of said surface, a combined hinge-lug and stop member comprising a piece of thin metal formed with an elongated upstanding part serving as a stop for a hinged cover, and integral end parts formed substantially at right angles to the upstanding part and forming therewith a substantially U-shaped construction n top View, integral lugs extending from an edge of said U-shaped construction and extending through openings respectively in the top of the body and being bent over on the under surface of the body, and hinge-lugs for a cover integral with said U-shaped construction.
