HINGE Filed Sept. 3, 1930 tening means being normally concealed.

Patented May 12, 1931 Application filed September 3, 1930. Serial No. 479,533.

stems l0 and 11 extend from opposite ends of this key 9 and are integral therewith. On the stem 11 is rotatably mounted a movable key 12 corresponding with key 9 in configuration so as to fit snugly in the slot 6. The pintle has a head 13 connected to the stem 11 and the movable key 12 is held between this head and the key 9.

When it is desired to join the members of the hinge the two leaves are placed in such positions that the slots 6 and S will register; The keys 9 and 12 are then placed in alignment and the pintle is inserted bodily into the ears so that stem 10 will be fitted in bore 7, key 9 will be fitted in slot 8, and key 12 will be fitted in slot 6. The parts can then be secured together by screwing a nut 14 on to stem 10. The hinge leaves can now be turned relative to each other, it being understood that the pintle will. be held against rotation within ear 4 by key 9, but ears 2 and 3 are free to rotate on the pintle because key 12, which is engaged by ear 2, is rotatably mounted. As soon as the two keys move out of align ment it becomes impossible to withdraw the pintle. As the re acive positions of the keys cannot seen wh'le the parts are assembled, the pintle general y cannot be withdrawn readily except by a person or persons fully acquainted with the construction of the parts.

Under some conditions it is desirable to mount the hinge detachably. For this purpose the back faces of the leaves 1 and 5 can be formed with dovetail grooves 15 in each of which is secured a spring strip 16. An attaching plate 17 having beveled sides is adapted to be slid into the groove 15 which is closed at one end. A longitudinal groove 18 is formed in the attaching plate and has a transverse shoulder 19. While the parts are being assembled one end of spring 16 will be received in groove 18 and when the plate comes against the end wall of groove 15 the spring will snap into engagement with shoulder 19 so as to prevent accidental separation of the parts. Openings 20 can be extended through plate 17 for the reception of screws used for attaching the plate to the structure to which the hinge to be connected This invention relates to a hinge for use on automobile doors, tire covers and at other places where it desirable to employ a separable hinge utilizing a removable pintle.

One of the objects of the invention is to provide a hinge having a pintle which is securely fastened in position except when the leaves of the hinge are brought to predeter mined relative positions at which time it is possible readily to remove the pintle and thereby permit separation of the parts.

Anotherobject is. to provide simple and eflicient means for fastening the leaves to structures connected by the hinge, said faslVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described andclaimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings:

Figure 1 is a front elevation of the hinge.

Figure 2 is a rear elevation thereof.

Figure 3 is a section on line 3-3, Figure 1.

Figure 4 is a section on line t-l, Figure 1.

Figure 5 is a perspective view of the pintle.

Figure 6 is a perspective view of one of the attaching plates.

Referring to the figures by characters of reference, 1 designates a hinge leaf having spaced ears 2 and 3 adapted to receive between them an ear 4 extending from a hinge leaf 5. The upper ear 2 is formed with a slot 6 extending therethrough while the lower ear 3 has a central bore 7. The intermediate ear 4 has a slot 8 which corresponds with slot 6 and is adapted to register therewith when the two leaves 1 and 5 are brought to predetermined positions relative to each other.

As shown in Figure 5 the pintle of the hinge includes a key 9 so proportioned as to fit within slot 8 and to slide through slot 6 when the slots are register, Aligning After plates 17 have been connected to relatively movable parts by means of screws 21 or the like and the hiige leaves have been slid into engagement with and secured to plates 17, it becomes'impossible to detach the hinge unless the leaves are folded bacl; one upon the other and a screwdriver or the like forced into the open ends oi? the grooves 18 for the purpose of shitting springs 16 out of engagement with ShOllldQl'S 19. lVith the snring thus held in each leaf, 'said leaf can he slid out of engagement with its attaching plate.

As has already been stated a hinge such as herein desiwribed can be used advantageously on automobile doors because the attaching means, employed are fully'concealed but it is possible whenever desired either to separate the parts of the hinge or to remove the hinge bodily either from the door or from the body of the vehicle; The hinge can also be used advantageously on tire covers such as are trcquently mounted above wells in running boards, or on supports at the back 01 vehicles; In fact the hinge will be found advent: wherever it is desired to permit the hinges and bodily detachment of the leaves from the parts 7 on which they are mounted,

WVhat is claimed is 1. ,A hinge including-leaves, a pair ol ears carried by one of the leaves, there being a slot in one of said ears and a bore in the other ear, an intermediate ear extending from the other leaf having a slot movable into and out of register with the first named slot, a pin tle having a 'key fitted in the slot in the intermediate ear and adapted to withdraw through the other slot when said slots are in alignment, oppositely extending stems on said key extending through'the respective ears of the pair, and a key rotatably mount? ed on one of the stems and removably seated inthe slot in one of the ears of the pair.

2. A hinge including'a leaf havinga pair of cars one of which is provided with a slot and the other with a bore, another leaf having an intermediate ear provided with a slot, a pintle including an integral key seated in the intermediate ear and oppositely extend ing stems in the respective ears of the pair, a head at one end of the pintle, a key rotatably mounted on one of the stems between the head and the integral key and seated in the slot in one of the ears of the pair, and means for securing the pin-" e within the ears.

3. A'hinge includi a leaf having a pair of ears one ofwhich is provided with a slot and the other with a bore, a second leaf hav-' ing an intermediate ear providedwitha slot,

the slotted ears being relatively rotatable to geous eparation of alignment for insertion of the pintle into the aligning slots with the keys seated in the re spective slots.

l. 'A. hinge including separable leaves each having a groove extending thereinto from one edge, a spring secured in the groove, an attaching plate slidable longitudinally into the groove, and means carried by said plate for engagement by the spring to hold the plate and leaf against separation.

5. A hinge including separable leaves each having groove extending thereinto from one edge, a spring secured in the groove, an attaching plate slidable longitudinally into the groove, means carried by said plate for engagement by the spring to hold the plate and leaf against separation, said means including a spring receiving groove extending longitudinally of the plateand provided with a shoulder-' tor engaging the spring, said groove being opened at one end to expose the spring for engagement by a releasing device.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
