HINGE.

AZOASl Specifici-#cionof Letters'Patent. Patented Julie 20,1922,

Application filed .Tuly 10, 1920. Serial No. 395,291.

Be it known that I, PETER GohLET, a, citizenv of the United States, residing at Aurora, in the countyof Kane and State 'to quantity manufacture and present day shop methods. Another object is to produce a construction which will permit the door to overlap a portion of the door frame,thus preventing the occurrence of acrack or opening at the hinged margin of thedoor and producing a tight construction which effectually prevents the access of a prying tool. Another object is to provide a construction in which the front surface of the door may come flush with the front surface of the door frame. Another object vis to provide a construction such that the door will he held tight when closed, thus topprevent rattling-also to enable the door to be swung fully open, that is, through an angle of substantially 180 degrees.

l accomplish my objectsby the construction illustrated in the accompanying drawings in which- Figure l is a perspective'view' of a cabinet or other receptacle embodying my invention;

Figure 2 is a face viewk on an enlarged scale showing the slotted portion of the door, the hinge plate, and adjoining portions of the door frame;

Figure 3 is a plan section on the line 3 3, Figure 9., showing the door in closed position;

Figure l is similar to Figure 3, but shows the door open instead of closed;

Figure 5 is a perspective view of the hinge plate or lug; l

Figure 6 is a plan section analogous to Figure 3, but showing a type in which the door frame is flush instead of countersunk;

Figure 7 is a front view of the type shown, in Figure 6. ln this case there is a single hinged plate which is providedwith three separate but integral lips which enter the slots for hinging the door in place.

Like numerals denote like parts throughout the several views.

ln the illustrated form selectedtoeXplain the principles of the inventionlthe're isa rnetalliodOOr frame l, the plane of which is substantially coincident with the Vplane of the door 2. The framemay or may'notv be part o f a receptacle or cabinet, but inthe present case l have illustrated a metallic cabinet 3 secured to the 'baclrof the frame to form a receptacle.

Adjacent to the hinged margin of the door are one or more slots 5. They are nearto but spaced from the edgeof the door so that the slots are in reality perforations or elongated holes.

ln the form shown in Figures lto el the door overlaps a portion 8'of the door frame, thisoverlapped portion being countersunk so that the front surface of the door lies substantially flush with the front surface of vthe frame. As the result of this overlapping there is no crack between the edge 'of the door and the edge of the frame, as in ordinary door constructions, and furthermore the countersunk portion 'forms a closure for'the rear of the slots.l

Fastened tothe front'of the door frame is a plate l0 having a curved lip l2 which passes in front of the doortand then curves backward so as to extendinto and through the slots 5, and preferablyterminates' in contact, with the yfront surface of the countersunlrportion 8. ln the form illustrated these plates l0 are of'metal and secured by spot welding or other approved method to the front of the door frame. aIn the best form the vertical dimension of the lips l2 is substantially equal to the vertical dimension of the slots, the result being that the lips lill the slots from topto bottom and prevent vertical movement of the door in either direction. l have denoted the portion between the slot and the adjacent edge of the door by the numeral 6. By preference this portion, which is somewhat analogous to the pintle of an ordinary hinge, is offset outward from the plane of the door. The result is Vthat it comes somewhat close to the inside of the lip l2 and thus holds the door close against the door frame when closed. It also permits the door to be swung more widely open-for example, under ordinary conditions it may swing through `an angle of 180 degrees.

In the illustrated form the door frame is rectangular so as to cooperate With all tour margins of the door, and it is desirable in many cases to have the door overlap the trame at all four of these margins. The overlapped portion ot' the door trame mayv be countersunk at the other three sides as well as the hinged Vside 8, it desired.

In practice, when the parts are construct-v ed as described, the door is supported` upon the lips l2 of the lugs l0 and is tree to swing about them as an axis, the curvature ot the lips being suficient to permit 'tree motion. @n account of the overlappingy otpthe door and door frame, the closure is very effective, and no cracks are visible either at the margin of the door or at the slots 5.

In Figure 6 I have shown a modification in the sense that the door trame, instead of being countersunk at the part 14, is overlapped by the door and lies in the same plane with it. In this case the front surface ot the door will not lie iiush with the front surface of the trame, but as the door is ot sheet metal, the two surfaces will not be much out of line. In other respects the operations and results are the same.

In Figure 7 a plate l5 is providedv which is analogous to the plates 10, but is elongated so as to be provided with three integral lips 16, 16. These, however, are formed in the same manner as the lips l2 and fit into three separate slots 5.

It will be evident to Athose familiar with sheet metal working Vthat the construction described and illustrated lendsitseli readily to quantity production. T he parts may all be produced by the aid of dies, thus renden ing them interchangeable and economical to make. Furthermore, the construction is e1"- fective, for cracks at the margins of the dooiare avoided, and hence it is practically impossible even when comparatively thin gauge metal is employed,to gain access to the interior of the receptacleby the aid ot a jimmy or prying tool. Furthermore, the construction is practically dust proof, for the overadvantage is that on account of the outward offset of the portion 6 ot the door and the fact that it vtits fairly closely with the lip l2, the door when shut is held close to the door trame, 'turthern'iore, the Vdoorvis enabled to swing open substantially va full 180 degrees.

Having thus describedmy invention, what I claim as new and desire to securebyy Letters Patent, is: i i

l. In combination, -a sheet metal doorl frame countersunk along one ot the margins ot the opening, asheet metal Adoor overlapping the countersunlrvportion of the door trame whereby the 'front of the door is approximately flush withl the frontr of the frame, the Vdoor having a slot running par allel with the overlapping edge oit' the, door near to but spacedtherefrom, and a plate fastened to the iront surface of the doorv trame and overlapping the front of the'door sutliciently to extend to the slot therein, said plate projecting through the slot and ei;-V

tending substantially tol the countersunk portion of the doon trame.

2. In combination, a door frame, a door adapted to overlap the trame at one edge, the door having a slot in the overlapping portion, and a lug fastened to the door 'frame and having' a lip adapted to pass to the front ot the door and thence backwardvinto the slot for hinging the door to the frame, the lip being concave on the inside and the portion oil metal between the slot and the adjacent edge of the door being Loffset outward for holding the door tight shut.

In witness whereof, I have hereunto'subscribed my name.

` PETER GOBLET.
