Description

Patented Aug. 22, 1933 UNITED STATES PATIENT OFFICE 1 Claim.

My invention relates to hinges of the particular type having removable hinge pins and the principal object of my invention is, to provide a hinge wherein the plates are provided with interlocking means that will effectually-prevent the door or panel with which the hinge is associated, from being removed from its frame after the hinge pin has been removed from the hinge.

In many structures having hinged doors, panels and the like, the hinges are arranged between the doors and panels and the surrounding frames, so that the connected portions of the hinge plates and the hinge pins are located externally of the door or panel and its frame and where such condition exists, it is possible to remove the pins from the hinges and then remove the door or panel even while the same is locked and it is the purpose of my invention to provide the hinge plates of such hinges with interengaging projections that will effectually prevent the door or panel from being removed while in locked condition and after the hinge pins have been removed.

A further object of my invention is, to provide a hinge of the character described that is relatively simple in construction and which adds very little if any cost to the manufacture of the hinges and which will in no wise interfere with the setting or applying of the hinges to the door or panel and the frame in which the same is located.

With the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:

Fig. l is an elevational View of a hinge constructed in accordance with my invention.

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1.

Fig. 3 is a horizontal section taken through the edge portion of a door or panel that is connected to a frame by my improved hinge.

Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, 10, 10 designate hinge plates which may be of any size and construction and said plates being provided with suitably lo- 00 catecl apertures 11 that receive screws or like fastening devices.

The adjacent edges of the plates are provided with interengaging tubular portions 12, through which passes the usual hinge pin 13.

Formed through one of the hinge plates, at or near the central portion thereof, is a countersunk aperture 14, and extending across same and preferably parallel with the vertical edges of the plate, is a small lug or plate 15 that projects a short distance outwardly from the face of the Go plate.

Formed in the other one of the hinge plates and positioned so as to receive the lug or plate 15 when the hinge plates are closed, is a slot 16 and formed integral withthe .plate in which said slot is formed and to the sides thereof, are outwardly projecting lugs 17 of such size as to readily enter the countersunk opening 14 to the sides of lug or plate 15.

When my improved hinge is properly applied 7Q to a door or panel I) and to the frame 'or structure F that encloses said door or panel and the door or panel is closed, the hinge occupies the position as illustrated in Fig. 3 and under such conditions the integral plate or lug 15 occupies a .75 position between the lugs 17 on the opposite plate and said lug or plate 15 passes through the aperture 16.

Under such conditions it is practically impossible, without breaking the door or panel or the 0 hinge, to remove the door after removing the hinge pin, for the interengagement of the lugs 15 and 17 effectually prevents the hinged edge of the door from being withdrawn from the frame or surrounding structure even though the door .85 or structure be shifted laterally to its limit of movement toward the side of the frame or surrounding structure that carries the look.

In some instances, and particularly on'hinges having hinge plates of extra lengths, it may be 9 found desirable to provide each plate with two or more sets of the interengaging lugs.

The lugs 15 and 17 all project from the exposed faces of the hinge plates when the hinge is properly applied to the door or panel and the frame therefor and therefore said lugs in no wise interfere with the setting and securing of the hinge plates to the door and frame.

The lugs 15 and 17 are formed integral with the plates either by casting or by being pressed from the material from which the plates are formed and in some instances the lugs 17 may be dispensed with and the lug or plate 15 shortened so as to extend between the lugs 1'7 to the face of the plate between said lugs.

Thus it will be seen that I have provided a hinge that is relatively simple in construction, inexpensive of manufacture and saidhinge having interengaging means that effectively prevents the door to which the hinge is connected from being provided with a diametrically arranged slot that extends through the plate that carries the lug, the other plate being provided with a countersunk aperture of such size and located so as to receive the lug on the other plate when the two plates are closed'against each other and a lug extending diametrically across said aperture and projecting outwardly from the face of the plate in which said aperture is located, which lug is adapted to enter the slot in the hemispherical lug when the hinge is closed.
