I Patented Jan. 1, 1935" PATENT OFFICE SAFE'IIFYv HINGE Joseph Bontemps, Richmond Hill Circle, N. Y., as-

signor to Hattie Smith, Brooklyn, Y.

Application October 22, 19 32, No. 639,009

2 Claims. (01. 16-136).

My-invention relates to a hinge construction particularly adapted for .automobile doors and.

which due to its novel assembly and mountin permits of a minimum space between the hinge edge of the door and the body of the car proper, thereby eliminating all danger of persons being injured by having their fingers crushed on the closing or opening of the door aforesaid.

A further object is to provide a hinge whereby the door is easily removable, and also easily remountable, either function being performed with a minimum of eifort. This is, of course true, only after one of the hinges has been removed.

Other objects will appear from a consideration of the detail of construction of my invention.

In the accompanying drawings, Fig. 1 shows a section of an automobile having a door which is supported by and swings on a hinge that bears upon members 8, 9 at the lower part of the door and on members 10, 11 at the upper part thereof.

Fig. 2 is an exposed sectional view of a single solid ball bearing hinge and its associated parts.

Fig. 3 is a plan sectional view on a line 33 of Fig. 2. This figure exposes 'the ball in its bearing, and also shows the door in a partly open position, the latter designated in broken lines.

Fig. 4 is a side elevation of an automobile sectionally exposed showing in. detail the upper and lower members of the safetydoor hinge.

Fig.5 is a view on a line 5-5 of Fig. 4 showing a section of the car door in an open position.

Fig. 6 is a cross-section view of a thrust ball bearing type swinging hinge bearing on a line 6--6 of Fig. '7.

Fig. 7 is a detailed cross-section of a hinge assembly showing a thrust bearing housingwith a pin projecting through a bushing which holds the roller thrust bearing in place.

Referring specifically to the'drawings. The frame of the door 2 consists of a door jamb 3 and horizontal frame bracings 4, 5 and 6, (Fig. 4). On-the vertical door jamb 3 are fastened inverted L-shaped hinge members 9 and 11 by means of screws 43 which arescrewed into bushings 14 and 15 that serve to give substantialsupport to the structure just described. The hinge members 9 and 11 have a curved surface relation with each other at their contacting surfaces to conform to the curvature of the edge surface of the door jamb 3 and the hinging edge of the door 2. This is clearly illustrated in Fig. 6.

, The hinge members 8 and 10 are likewise L-shaped and are similarly curved at their bearing surfaces and are secured to the car body 1 by means of screws 43 which are screwed into member 11.

bushings 16 and 17 on the frame 7. Mounted at the lower portion of the door 2 between the hinge members 8 and 9 is a thrust bearing housing in two sections 21, 22, in which the .balls 23 are set in equidistant positions. The housing maybe a r 5 standard thrust bearing type commonly employed for shaft bearings or the like.

The hinge member 8 has a bushing 25 through which a pin 26 projects. The bushing projects through the thrust bearing 21, 22 and into hinge 10 member 8. The bushing 25 is further held by a collar 24. The pin projecting through the-thrust bearing assembly as shown serves as a safety factorin maintaining a coacting relation of the ringe members 8 and 9 as well as to ensure 15 smoothness and ease in opening and closing the door 1.

The upper hinge bearing is similar in construction to that describing the lower hinge.

The part 27 in Fig. 5 is a metallic covering placed" over the inner exposed portions of the hinge members 8, '9 and 10. 11. This covering forms an added protection at such times when the car door is opened. The members 28 are screws that fasten the covering 27 to the car door.

In the event it is desired to remove the door 2 from the car body, the screws 28 seen in Fig. 5 are unscrewed after which the covering 27 is removed from the door hinge member 11 which 30 is then exposed as seen in Fig. 4. The screws 43 are then unscrewed from their companion bushings 15. This enables the removal of the hinge After the operation described is performed it is possible to lift up the door and with it the hinge member 9 clear of the hinge member 8 adjacent thereto at the lower portion 1 of the door. The operation described can be readily performed by one man without undue strain on the door or the hinges thereof.

Referring to Fig. 2, this figure illustrates sectionally a modification of the hinge bearing utilizing a single solid ball bearing hinge arrangement, the ball being shown at 32 fitted into suitable socket bearings in each of the upper and lower members 33 and 34. The member 34 is secured to the bar body.

Fig. 2 particularly illustrates an assembly of the lower portion of the hinge. Reference character 35 represents the outencovering of the car body. and 36 the outer covering of the door. Reference characters 37 and 38 designate screw casings for holding screws 39 which secure the hinge member 34 to the car body. a

In Fig. 3, 41 represents the'in'side door coverfasten the partition 12 to the hinge member 8.

The wood screwsindicated by 20 are provided to secure the portion 12 in the proper position.

The close hinge relation of the door and thecar body is best seen in Fig. 6 which illustrates the movement of the door on its axis at 26 and the relation of the shell 12 of the car body and that of the metal outer section 13 of the door.

The close relationof the car body and the door thereof shown in Fig. 6, as already stated is maintained the entire length: of the door-with the exception, perhaps, of the extreme bottom section ofthe car door which hasan outward curved conformation in accord with the design of the car body."

It will thus be seen because of the curved relation of the two bearing surfaces of one hinge attached to the convex edged surface of the door jamb and the companion hinge member thereof attached to the concave hinging edge of the door, that the hinging area of the door which includes the entire space between the upper and lower pairs of hinge members will remain constantly flush with respect to their coincident areas regardless of the position of the door, whether opened or closed; and that there are no projections, depressions or openings between the door and that portion 01' the car body that supports the. door and the hinges thereof in the entire hinging door edge area that might cause an object such as a person's fingers to be enmeshed in the space aforesaid. 1

What I claim is,

1. In a concealed hinge of the character described, a pair of inverted L-shaped hinge plates adapted to be secured to a door and jamb respectively, said plates having their leg portions arranged in superposed relationship with their stems opposed and spaced 9. distance substantially the length of the leg portions; the latter having recesses formed in the adJacent opposed portions thereof, an apertured bearing having a ballreceiving groove mounted in each recess, a a

pivot pin having a bushing, a collar secured to the bushing, said collar positioned within an aperture of one of the bearings with the pin projecting through the apertures of both bearings, and a protective cover for said hinge plates. 4

2. In a hinge of the character described, a pair of inverted L-shaped hinge plates, said plates,

having their leg portions arranged in superposed relationship with their stems opposed and spaced a distance corresponding substantially to the length of a leg portion, each of the latter having a recess, an apertured, grooved bearing mounted therein, balls in said groove, a pivot pin extending through the recesses, said plates arranged to be covered by a protective member.
