2 Claims.

This invention relates'to hinges for automobile and other doors and particularly to the so called concealed hinges therefor.

The general object of this invention is to provide a hinge which is entirely concealed and yet which is strong and serviceable and which pro= vides for secure attachment of the door to the hinge and of the hinge to the body pillar, and a further object is to provide a hinge particularly adapted to be used with car bodies having a considerable turnunder sweep and which is so constructed as to allow the door to swing far enough out but entirely clear the body and any ornamental beading thereon.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein:---

Figure 1 is a horizontal section through the body pillar and door pillar of a car showing my hinge applied thereto, the figure showing in dotted lines the door swung to its open position;

Figure 2 is a vertical section on the line 22 of Figure 1;

Figure 3 is a vertical section on the line 3-3 of Figure 2.

Referring to the drawing, A designates the body pillar of the car and B the door pillar. The body pillar A is provided with a front transverse face a and the doorpillar B is provided with a front transverse face b which opposes the front face a of the body pillar, as shown in Fig. 2. The body pillar is deeply recessed or cut away in the front transverse face thereof at the point where the hinge is to be applied as at a and the confronting front transverse face of the door pillar is deeply recessed or cut away at 2)., Disposed within the cut-away portion a. of the body to pillar are the two angular supporting plates it and M which form a, stationary hinge leaf and which are disposed in shallow recesses a'in the faceof the door pillar above and below the deep I recess 11 therein. Each of these plates has a it horizontal extension it, these extensions extending into the recess a and these extensions are connected by a pintle 63 arranged adjacentto.

the outer longitudinal surface of the body. The plates it. and M are held, to the body pillar A by means of screws M. The plntle i3 may be made in one piece with the plate extensions E2 or may be driven into these extensions.

Disposed between the extensions I2 is a hinge arm I5 which at one end is formed with the t5 elongated eye or sleeve it which surrounds the pintle I13 and rotates thereon. This eye is slightly longer than the arm as shown clearly in Figure 2 so as to reduce friction. The recess a is so formed that the arm l5 fits-snugly in this recess as shown in Figure l and bears against 5 the end and bottom wall of the recess when the door is closed thus limiting the closing movement of the door. The member it at its free end is angularly extended at ii and this angular extension ii is bifurcated, that is recessed at it m at its middle. The portion ii at its outer end is fiat and wide as shown in Figure 1. The door B has a shallow recess at b on the inner side of the deep recess 12 for the reception of an elongated plate, hinge leaf or hinge element l9 which is attached to the-door pillar by the screws 2t and which at its middle is formed with an \outwardly projecting lug 2.9 which fits within the recess it and bears flat against the inner wall of the recess.

It will be noted that the end face of the angular portion ll of element it fits flat against the outerface of the plate it and that the lug it has an angular face shown in dotted lines in Figure l which flts flat against the vertical face of the recess it- A screw or pin 22 extends downward through the angular extremity ill and intersects the recess it and passes through the lug it. Because of the flat contacting faces between the plate it and the ends of the angular portion ill, there is no turning movement of the plate 99. with relation to the element it but these two elements it and it are held rigidly engaged with each other by the pin 22.

Attached to the face of the body pillar A, is a metallic cover or plate 23 which extends over the sleeve it and over the recess a. and beyond this recess and is then bent inward at 26 over a strip 25 on the body so that this projecting portion of the plate 23 extends partially over "the recess 12 in the door pillar. The door pillar is also provided on its face with the cover or plate 26 which is extended partially over the recess 22 and then returned upon itself over the strip 211 on the door as at 28. Thuswhen the door is closed, the front edges of the cover plates 23 and 26 are opposed and close together and offset forwardly from the joint between the body .and door pillars whereby the joint between the door and the body is practically closed and is 50 practically unobservable while the hinge elements are entirely enclosed and invisible Thisoffsetting of the joint between the plates 23 and 26 is preferably effected by extending the body cover or plate 23 beyond the front transverse 55 body are ordinarily formed with an outwardly projecting molding or bead which is designated C in Figure 1 whereby a turn-under sweep is pro-.

duced on the lower part of the body relative to the upper part thereof. This renders it impossible to use the ordinary or concealed hinge because the door cannot open far enough before it strikes this molding C. My improved hinge is designed to overcome this difiiculty as shown in Figure 1 which illustrates the fact that the door may be swung farther outwardly away from the body and opened fully or to the dotted lined position before the molding or bead on the door will strike the molding or bead C on the body. Thus my hinge can be used for enclosed cars because it is constructed to permit the door to open far enough to clear the widest point above the body at the belt molding.

Of course, it ,will be understood that two or more of these hinges are to be used on each door and it will be seen that my improved hin'ge is heavy enough to carry the enclosed body door I .and that it allows the door to swing far enough out to clear the body.

By providing the body pillar with a deep recess a for the-reception of the angular extension or arm I5, I! when the hinge is closed and a deep recess b in the door pillar, it is possible to open the door fully and clear the laterally projecting swell or salient part C of the body which is formed thereon by the molding above the lower turn-under. Upon opening the door the recess b in the door pillar receives the outer front corby dotted lines in Fig. l.

This construction also permits the recess a of the body pillar and the recess b of the door pillar to be concealed by the covers 23, and permits the meeting edges of these covers to be located on one side or offset outwardly or forwardly from the joint between the body and door pillars and thus effectively close this last-mentioned joint while at the same time fully concealing the hinge when the door is closed and still permitting the door to be opened fully inasmuch as the door pillar recess 22 at this time not only receives that part of the body adjacent to the outer front corner of the body pillar but also the outer edge portion of the body pillar adjacent to the turn 25 of this cover. r

The form of this hinge and the manner of mounting the same therefore permits of completely concealing the hinge and enables the door to clear the laterally projecting swell on the body 'face of the body pillar A and terminating the front edge of thedoor cover or plate 26 short of I this construction lies in the fact'that the member l9 which is attached to the door or door post is detachable from the hinge element I! so that if the door has to be taken off the body, this can be accomplished by simply removing the bolt or screw 22 and pulling the door away from the remainder of the hinge. Thus the hinge may be removed from the door without scratching the pane or removing the trimming on the door or body or removing any of the attaching screws; 20

I. A hinge mounting for automobile and other doors comprising a body pillar provided in its front transverse face with a recess, a door pillar provided in its transverse front face with a re- 25 cess adjacent to its outer front corner and an elevation adjacent to its inner front corner, and a hinge including a body leaf secured to the body pillar, a door leaf secured to said elevation of the door pillar, an arm projecting from said door leaf into the recess of the body pillar, and a pintle arranged in the recess of the body pillar adjacent to the outer front corner thereof and pivotally connecting the body hinge leaf and said arm, said pillar recess being adapted to receive the outer front corner of said body pillar upon turning the door into its open position.

2. A hinge mounting for automobile and other doors comprising a body pillar provided in its front transverse face with a recess, a door pillar 40 provided in its transverse front face with a recess adjacent to its outer front corner and an elevation adjacent to its inner front corner, a hinge including a body leaf secured to the body pillar, a door leaf secured to said elevation of the door 45 pillar, an arm projecting from said door leaf into the recess of the body pillar, and a pintle arranged in the recess of the body pillar adjacent to the outer front corner thereof and pivotally connecting the body hinge leaf and said arm; a 59 position of the door.
