FATE FF i HINGE CONSTRUCTION.
Application filed July 30, 1921. Serial No. 488,618.
To all whom it may concern.
Be it known that I, DAVID Boivnns, a citizen of the United States, residing in Laurel Springs, New Jersey, have invented Hinge Construction, of which the following is a specification.
One object of this invention is to provide a relatively simple, inexpensive, substantial form of hinge for connecting the lid to the body of a box, which shall be of such a nature as to be quickly and conveniently made and assembled.
I further desire to provide a hinge construction particularly adapted for use in pivotally connecting two sheet metal structures and which while avoiding the use of an independent connecting pin or pintle, shall possess the characteristic advantages of a hinge employing such a member.
These objects and other advantageous ends I attain as hereinafter set forth, reference being had to the accompanying drawings, in which,
Fig. l is a perspective view of a box to which my invention has been applied;
Fig. 2 is a fragmentary perspective on.a larger scale than Fig. 1, illustrating the detail construction of my hinge;
Fig. 3 is a fragmentary elevation of the rear side of the box showing one of the hinge members ready for bending into its final position; I
Fig. 4 is a fragmentary end elevation similar to Fig. 3 and on a larger scale, illustrating the detail construction of a portion of the hinge;
Fig. 5 is a rear elevation of the cover;
7 Fig. 6 is an enlarged vertical section on the line 6-6, Fig. 3; and
Figs. 7 and 8 are enlarged vertical sections respectively taken on the lines 77 and 88, Fig. 4.
In the above drawings l'rep'resents the bottom, 2 the front and 3 the rear sides of a sheet metal box having ends 4-4. This box has a cover including a body 5, a front 6, a back 7 and two end members 88. For the purpose of movably connecting this cover to the box I form in the rear side 8 thereof an elongated inwardly extendingie cess constituting a bearing 9 of semi-circular section extending adjacent and substantially parallel with the upper edge of said back.
At two points, preferably although not necessarily adjacent the ends of this bearing recess, I out the metal of the back to form tongues 10 which project outwardly and downwardly. The rear side 7 of the cover has its bottom or free edge curled up the tongues 10.
In assembling the cover on the box said v tongues 10 are caused to pass through the openings 12 of the rear side of the cover immediately over its curled up edge 11, around which they are bent or curled as in-' dicated at 10 in Fig. 7. The diameter of the curled up edge 11 is such that it more or less closely fits into the bearing formed by the pressed in portion 9 of the rear side of the box so that it is freely rotatable-in the latter and is retained in place by the curled in tongues 10. The latter also serve as bearings for the parts of the edge 11 which extend through them so that the lid is free to rotate on the hinge provided by the coactingparts 9, 10 and 11 and is firmly held in place.
Since the width of the tongues 10 is substantially the length of the recesses or openings 12, lateral movement of the cover relative to the box is efiectually prevented and if desired to give the hinge a complete appearance I may force outwardly portions of the rear of the box, as indicated at 13, immediately adjacent to and in continuation of the ends of the curled up edge 11 of the cover.
It is particularly to be noted that the con struction is simple and inexpensive in the extreme, being capable of rapid assembly, especially since there is no requirement for a pin or pivot member as is usually the case in similar hinges.
l. The combination in a hinge of two sheet metal members of which one has a curled up edge and openings adjacent said edge; a second member having a depression formed to serve as a bearing for the curled up edge of the first member and having tongues extending through the openings of the latter around the adjacent portion of said curled up edge.
2. The combination of a sheet metal box having tongues struck up from its rear edge; witha cover having openings in its rear edge positionedto receive said tongues and formed with its edge rounded adjacent said openings, the tongues being, formed to serve as bearings for the rounded portions of the edge.
3. The combination of a sheet metal box having tongues struck up from its rear side and having an elongated indentation adjacent the tongues; with a cover having openings in its rear side positioned to receive the tongues and formed with its edge curled up to rotatably operate in said in dentation, the tongues being curved around openings in its rear side positioned to re ceive the tongues and formed with its edge curled up to rotatably operate in said indentation, the tongues being curved around said curled up edge to hold the cover .in
place, the rear side of the box having outwardly projected portions aligned with the ends of the curled up edge of the cover. 7 DAVID BOlVERS.
