COVER STRUCTURE FOR CAGE-TYPE HOLLOW BODIES Filed Feb. 20, 1950 2 SHEETSSHEET 2 INVEN TOR. Gearge 5. flame Patented Apr. 21, 1953 COVER STRUCTURE FOR CAGE-TYPE HOLLOW BODIES George B. Hume, Kansas City, Mo., assignor to Hume Manufacturing Company, North Kansas City, Mo., a corporation of Missouri Application February 20, 1950, Serial No. 145,111

6 Claims. I 1 This invention relates generally to closures for containers and the like, the primary object being to provide actuating structure for skeleton closures of the kind forming the subject matter of U. S. Letters Patent No. 1,921,295, dated August 8, 1933, and entitled Incandescent Lamp Guard."

The closure structure of the aforesaid patent and including a plurality of interlocked swingable loops, has for many years proved entirely satisfactory, but there has existed a somewhat diflicult problem of providing handles for the containers with which the closure is used, not only for the purpose of facilitating handling of the container itself and in some instances hanging of the same upon suitable supports during use, but from the standpoint of supplying actuating means to move the closure to and from an open position.

It is accordingly the most important object of the present invention to provide handle structure for skeleton closures of the aforementioned character that are swingably secured to the container in the same manner as the loop structure of the closure itself and each slidably interconnected with one of the loops of the closure for simultaneously imparting swinging movement to a pair of the loops and thereby actuating the closure with distributed. forces tending to prevent damage to the closure itself.

Another object of the present invention is to provide handle structure for skeleton closures formed to cooperate with parts of the container upon which the closure is mounted whereby the handles are held in a predetermined position and cannot be accidentally displaced from the desired, predetermined point at which pressure is to be applied to certain of the loops of the closure.

Other objects of the present invention relate to the way in which a pair of handles are formed to meet on the longitudinal axis of the container; the manner of presenting loops in the handles to permit hanging of the container; and the way in which the handles are releasably interlocked for holding the closure in the normal operative position.

More minor objects will be made clear or become apparent as the following specification progresses, reference being had to the accompanying drawing, wherein:

Figure 1 is a side elevational view of cover structure for cage-type, hollow bodies embodying one form of my present invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a top plan view showing the cover structure in an open position.

Fig. 4 is an enlarged, fragmentary, perspective view showing the handles separated and the cover structure partially open.

Fig. 5 is a side elevational view showing a modified form of cover structure.

Fig. 6 is a top plan view of the structure illustrated in Fig. 5.

Fig. 7 is an enlarged top plan view showing the cover structure of Figs. 5 and 6 in an open position; and

Fig. 8 is a fragmentary, cross-sectional view taken on line VIII-VIII of Fig. 6.

The cover structure forming the subject matter 'of this invention is shown in Figs. 1 to 5 inclusive, mounted upon a guard member for electric lamps of the well-known type commonly employed by mechanics and workmen generally.

The lamp guard includes a skeleton frame or body broadly designated by the numeral 10 mounted upon an elongated handle I2 that is tubular and preferably made from rubber or other insulating material. The hollow handle I24 has a conventional lamp socket (not shown) mounted therein for receiving an electric lamp l4 and for connecting with an extension cord I6 that is provided with the usual electrical conductors to connect with a suitable outlet.

Body l0 includes a pair of annular wire bands l8 and 20 and a plurality of elongated, spacedapart substantially parallel rods 22 within the spaced rings 18 and 2B and secured directly thereto by spot-welding or the like.

A split band 24 in opposed relationship to ring [8 receives the proximal ends of the rods 22 and circumscribes one end of the handle 12. Bolt and nut structure 26 on band 24 releasably joins the latter to handle 12.

Cover structure for the body In is broadly designated by the numeral 28 and is substantially identical with that disclosed in said Patent No. 1,921,295. Skeleton cover 28 includes a plurality of identical semi-circular loops 30 hingedly joined with the ring l8 by means of an eyelet 32 on the free end of each leg respectively of loop 30. The series of loops 3!! are continuous throughout the length of ring l8 and as most clearly illustrated in Fig. 3 of the drawing, one leg of each loop 30 overlies the leg of the loop 30 next adjacent thereto and the opposite leg of each loop 30 underlies its proximal loop 30. Consequently, as fully explained in the above mentioned patent, the cover structure 28 may be moved from the: normally closed position shown in Figs. 1 and 2 to the fully open position illustrated in Fig. 3 of the drawing, by grasping any pair of opposed loops 30 and swinging the same outwardly on the ring I8. There is a tendency however, for users to attempt to swing the cover structure 23 to and from an open position by merely grasping one of the loops 30, thereby causing damage to the cover by bending of the loops that must undergo the force necessary to actuate the cover. Furthermore, it is usually necessary in using extension lamps of this character, to hang the same from a suitable support while in use, and inasmuch as the cover 28 must be maintained free for opening and closing to replace lamps I l, handle structure broadly designated by the numeral 34, has been provided.

Handle structure 30 includes a pair of identical handles 36 and 38, each formed from an initially flat strip of bendable material. The elongated strip is initially twisted to present an intermediate stretch it that is perpendicular to the remaining lengh thereof and stretch at is provided with an elongated opening t2. One end of the strip is bifurcated} presenting a pair of fingers that are looped about the ring It in embracing rela tionship to one of the rods 22 and between the legs of one of the loops 30. It is noted that said oneloop is threaded through the opening 42 in stretch 40 for free sliding movement therein.

That end of the strip of material opposite to the fingers 4 3 is bent at an angle to stretch 4E1 to present an elongated straight portion 46 that terminates in an arcuate loop 43.

It is noted in Figs. 1 and 2 of the drawing that when the cover 23 is in the fully closed position, the handles 36 and 3B are together with the straight portions 46 thereof in interengaging face to face relationship on the longitudinal axis of body I0 and handle I2 and that the loop portions 48 extend outwardly in opposite directions from each other. When it is desired to open the cover 28, the handles 37 and 38 are grasped at the looped portions 48 thereof and moved apart to the position illustrated in Fig. 3 and when in such position, handles 36 and 38, as well asall of the loops .30, are in substantially the same plane through the ring I8.

Means for releasably interconnecting the handles 36 and 38 when the same are closed and together, includes a U-shaped clip 50 mounted on handle 38 in embracing relationship to the portion 46 thereof. One leg of the clip 50 is welded or otherwise aifixed directly to the outermost face of stretch and when the handles 36 and 38 are together, the opposite leg of clip embraces the outermost face of handle 36.

A sufficiently loose fit is provided at the fingers 44- to prevent lateral movement of the handles 36 and 38 whereby clip 50 may be rendered releasable as desired to open thecover 28. It is to be noted that as the handles 36 and 38 are actuated, the corresponding loops 30 thereof slide freely within the elongated openings 42 and force is applied to these loops at the bight thereof while the handles 36 and 30 swing on the ring I8; Handles 36 and 38 are held substantially at the bight of their respective loops by virtue of theinterlocking connection between fingers 44 and their corresponding rods 22.

In Figs. 5 to 8 inclusive of the drawings, there is illustrated a conventional trash burner, broadly designated by the numeral I00. Burner I00 includes a pair of opposed circular rings I92 and I04 interconnected by a plurality of spaced apart, elongated parallel rods by means of eyelets IfiB looped about the corresponding rings I02 and I04.

'A bottom I I0, taking the form of a grill within the burner I00 is secured directly to the rods I06 4 by welding in spaced relationship to the ring I04. A cover II2 including a plurality of loops II I hingedly secured to the ring I02, is identical in nature to cover structure 28 above described.

A pair of identical handles IIS and H8 are each made from a single length of rod-like material bent upon itself to present a polygonal grip I 20, a shank I22, a pair of diverging legs I24 and a pair of spaced-apart eyelets I26 looped about the ring I02.

The shank I22 includes a pair of stretches I28 and I30 disposed on opposite sides of a respective loop II4 adjacent the bight thereof. It is noted in Fig. 8 of the drawing that the stretch I30 of shank I22 overlying loop H4 is substantially straight throughout its length, whereas the stretch I28 that extends below loop H4 is offset with respect to stretch I30 presenting an elongated slot I32 for slidably receiving loop H4. The eyelets I26 formed on the outermost free ends of the diverging portions I24 are spaced apart a sufificient distance to embrace a plurality of eyelets I08 on ring I02 to thereby hold the handles H6 and I I8 against lateral sliding movement on the ring I02. It is to be noted that the grip portions I20 are bent at an angle with respect to the shanks I22, whereby grips I20 meet and register on the longitudinal axis of burner I 00 when the cover I I2 is in the closed position as illustrated in Figs. 5, 6 and 8. Handles H6 and H8, as Well as all of the loops II4, are in substantially the same plane through ring I02 when cover I I2 is open as shown in Fig. 7 of the draw 1 g.

Handles I I6 and I I0 serve not only as a means of moving the cover II2 to and from an open position but facilitate handling of the burner I I0 and carrying the same about when the operator extends his fingers through grips I20.

While the cover structure hereof has beenillustrated in connection with two differing types of bodies, 1. e., a lamp guard and a trash burner, it is to be appreciated that the principles hereof may well be applied for use on various receptacles differing from that chosen for illustration. By the sametoken, many other changes and modifications may be made within the spirit of this invention and it is therefore, desired to be limited only by the scope of the appended claims.
