May 14, 1940- s. B. ATwooD HINGE Filed Sept. 1'7, 193B Patented May 14, 1940 IUNITED STATES PATENTv OFFICE 11 Claims.

This invention relates to improvements in concealed ball and socket hinges for the doors of motor vehicles.

One of the principal objects of my invention is to improve and at the same time reduce the` cost of manufacture of the sheet metal socket members. These have been made heretofore in two stamped pieces, generally L-shaped in form, nested together and riveted at four points around Hi the socket portion.' While that construction is commercially practical and satisfactory, gener'- ally speaking, there are the objections that the design is too costly because of the .amount of sheet metal required and because of the labor '5 involved in riveting.

In the hinge of my invention, I propose having integral lugs or arms on one of the socket parts, arranged to be bent over the edge of the companion part at spaced points around the socket to clinch the parts together, thus simplifying the construction by eliminating the necessity of piercing holes for the rivets and lowering the cost further by eliminating the rivets and the costlier riveting operation.

I further propose to simplify the socket member and reduce the cost thereof by providing only one L-shaped sheet metal stamping with a semispherical socket portion in` the one leg thereof, and then instead of having a second l.'shaped socket piece to nest on the rst, I propose to provide merely a small cap piece for the socket portion of the L-shaped piece, the cap piece having a complementary semi-spherical socket portion to register with the semi-spherical socket portion in the L-shaped piece.

In the ball and socket hinge as heretofore constructed, the ball-headed gooseneck member was heretofore L-shaped, the attaching shank portion provided on the one leg of the l. being ar- 4o ranged tol be clamped onto the inner side of the door in substantially parallel relation to the outside of the door and body. However, that construction was objectionable because it interfered heretofore with the old construc- (oi. ifs-ies) The invention is illustrated in ing drawing, in which#- Figure 1 is a horizontal section through a portion oi a door panel and door showing a concealed ball and socket type hinge made in ac- 5 cordance with. my invention,v,this View being partly in section on the line I-I in iFig. 2, but showing the socket member in planview;

Fig. 3 is a sectional detail on the line 3--3 of Fig. 2;

Fig. 4 is a fragmentary side view of an automobile, the door of which is equipped with conl5 cealed hinges, like those shown in Figs. 1 and 2, the hinges appearing in dotted lines, and l Figs. 5 and 6 are views similar to Figs. 1 and 2, respectively, showing another hinge construction, Fig. 5 being a horizontal section with the 20 entire hinge appearing in plan View and Fig. 6 vbeing a vertical section on the broken line 6-6 of Fig. 5.

Similar reference numerals are-applied to corresponding parts throughout the views.

Referring first to Figs. 1 to 4, 1 designates the pillar and 8 the door, but it will soon be evident that `it is immaterial whether the socket, member 9 and gooseneck member I0 of. my improved gball and socket hinge are mounted onfgo the pillar and door, respectively, or vice versa. 'I'he pillar 1 is of the type that will be provided in a four-door car between front and rear doors, the door 8 being a rear door and there being also the accompanya front door 8a, a portion of whose ange ap- 35 pears in Fig. 1. The gooseneck member I0 is formed from .a single piece of rod material to provide a generally U-shaped shank II terminating at one end in a ball head I2 formed as an integral enlargement of the end of the shank. u

One arm I 3 of the U carries the ball head. and the other arm I4 in spaced vparallel relation thereto constitutes' the attaching shank portion. An elongated horizontal recess I5 of semi-circular form to accommodate one half of the cylindrical attaching portion I4 is provided by indenting a portion I6 of a sheet metal reenforcing member I'I in the door 8. A sheet metal clamp member I8 has an intermediate generally semi-circular portion I 9 to embrace the other 50 half of the cylindrical attaching shank portion I4 and is adapted to be secured to the edge of 'the door' by screws 2li entered through holes in the ends of the clamp member I8 and threaded in swedged holes 2| provided in the reenforcing u member I1 in the door. The holes at 2| are flrst pierced and then swedged by means of a punch, and thereafter are tapped to receive the screws 20, whereby to provide longer threaded holes and consequently better anchorage for the screws 20 than would be provided in the thickness of the reenforcing member I1 otherwise. The attaching shank portion I4 is preferably knurled, as at 22, to provide good gripping surfaces and accordingly avoid danger of the shank turning out of position or moving endwise out of position after it has been clamped.

The socket member 9 is formed from two L-shaped sheet metal stamping's 23 and 24 providing abutting attaching portions 25 and 26 parallel to the edge of the door pillar through horizontally elongated slots 21 in which bolts or cap screws 21a are passedto secure the hinge to the pillar by means of an iinier reenforcing anchor plate 28 welded or otherwise rigidly secured nside the pillar 1. 'I'he plate has swedged and tapped holes 28a to receive the bolts or screws 21a. The plate 28 has a U-shaped yoke portion 29 bridging the gooseneck member IIJ and ribbed lengthwise, as indicated at 30, to stiffen and strengthen the same. The other portions 3I and 32 of the sheet metal stampings 23 and 24 provide the socket 33 therebetween and are at right angles to the attaching portions 25 and 26, in a plane substantially parallel to the outside of the body. One half of the socket 33 is formed by a hemi-spherical socket portion 34 struck from the portion 3| of the stamping 23, the portion 34 having a channel-shaped portion 35 extending radially therefrom toward the edge of the door 8 in register with the longitudinal horizontal slots 3S provided in the portions 25 and 26 of the stampings, through which the gooseneck member I0 extends and is swingable in the opening and closing of the door. The channel formation 35 provides extra clearance for the arm I3 of the gooseneck member so that the door can be opened approximately 'I'he other hemispherical socket portion 31 registering with the socket portion 34 to dene the socket 33 therebetween is provided in the portion 32 of the stamping 24. There are inturned flanges 3B on the stamping 24 on opposite sides of the slot 36, and these flanges are joined to the semi-circular ange 39 surrounding the hole 4I) through which the arm I3 of the gooseneck member I0 extends from the ball head I2 disposed in the socket 33. The L-shaped flanges, interconnected as described, give the desired reenforcement for the socket member 9 and enable use of proportionately thinner sheet metal for the present purposes than would otherwise be feasible.

In accordance with my invention, instead of piercing the portions 3l and32 in circumferentially spaced relation around the socket 33 and then riveting said portions together, I provideintegral lugs or ears 4I on the edges of one of said portions, in this case the portion 32, adapted to be bent at right angles alongside the edges of the other portion 3I and again at right angles to clinch the portions together. This construction is simpler and more economical, and furthermore takes less time to assemble. The lugs hold the socket parts together just as securely as rivets, if not more securely. The portions 3l' and 32 in assembling are pressed together at the edges, in radially spaced relation to the socket portions 34 and 31, so that the sheet metal between these points is free to iiex, it being the practice to have the socket depressions in the portions 34 and 31 slightly under size with reference to the ball head I2, so that the ball head and socket parts will wear away as the ball head in-its first stage of service wears away the minor irregularities in the'socket 33 and on the ball head in seating itself. There will still be a slight amount of clearance between the portions 3l and 32 around the socket 33 after the ball head I2 has developed its seat in the socket portions 34 and 31, and in that way there is an automatic take-up for wear and consequently no danger of play developing and causing rattling. Graphite or other lubricant is spread on the ball head or in the socket portions at the time the hinge is assembled, and this lubrication lasts indefinitely.

In Fig. 4, the door 8a in the opening 42 in the body 43 is shown equipped with two hinges A and B constructed `as illustrated in Figs. 1 and 2. The bolts or screws 20 and 21a are given a preliminary tightening part way, enough to allow the gooseneck members I0 to turn with respect to the door and also permit the door to slide inwardly or outwardly endwise with respect to the shanks I4 of the gooseneck members. The socket members 9 under these conditions are also free to shift slightly with respect to the bolts or screws 21a. The slots 36,- as clearly indicated in Fig. 2, are wide enough in relation to the gooseneck members I0 extending therethrough to permit the desired range of angular adjustment of the gooseneck members required in vertical centering adjustment of the door. Ordinarily the socket members 9 can be located accurately enough so i that whatever in or out adjustment of the doors may be desired to secure alignment thereof with respect to the body and with respect to one another can be secured by sliding adjustment of the doors endwise with respect to the shanks I4. However, such adjustment of the doors is obtainable also by sliding the socket members 9 in or out with respect to the body 43 and pillar 1. Wedge-shaped shims may be used in the adjustment of the door, as described in my copending application Serial No. 135,068, led April 5, 1937, entered in the door opening around the door and adjusted by a workman inside the car vuntil each door has been wedged in approximately the desired position, centrally located in its door opening and properly lined up with the body and the other door, whereupon the bolts or screws 20 can betightened from inside the car to clamp the gooseneck members I0 in their adjusted relation'- ship to the door, before the doors are opened and the shims removed. When the doors are opened, the other bolts or screws 21a are tightened up and then the door can be closed again to re-check the adjustment, and any minor adjustment of either hinge can be made by loosening and re-tightening the bolts or screws thereof. Once the bolts or screws are tightened flrmly, there is no danger of the doors sagging or shifting in any way from their adjusted positions in the door openings.

'I'he hinge construction illustrated in Figs. 5 and 6 is generally similar to that of Figs. 1 and 2. However, the socket member 9a has only one L- shaped stamping 24a which is generally simi- .lar to the stamping 24 of Figs. 1 and 2, and,

instead of the companion stamping 23 shown in Figs. 1 and 2, a stamping 3Ia is provided as a companion piece for the portion 32a and having a socket portion 34a formed therein to register with the socket portion 31a on the stamping 24a to complete the socket 33a for the ball head I2a. In this case, there is also a channel formation 35a portion 32a of the stamping 24a.

on the stamping 3|a extending radially from the socket portion 35a and registering with the slot 36a. in the stamping 24a. The clinching lugs or ears 4la in this case are provided on the stamping 3Ia and bent over the edges of the The bolts or screws 21 are entered through slots 21 in the attaching portion 26a of the stamping 24a, and are entered in a tapping plate v28 provided in the pillar la. The stamping 24a has flanges 38a on opposite sides of the slot 36a joined at their wide ends to the ends of the semi-circular flange 39a surrounding' the hole 40a in the socket portion 31a through which the arm I3a of the gooseneck member extends from the ball head I 2a. This construction of the socket member involves the use of less sheet metal and results in a substantial saving in cost of manufacture, even though heavier gauge sheet' metal is.em ployed. 'Ihis hinge is just as strong and rigid as one constructed along the lines of Figs. l and 2.

The gooseneck member Illa, illustrated in Figs.4

ing member ila in the edge portion of the door 8. The clamp |80, cooperating with the shank I a is similar to the clamp I8 previously described and is arranged to Ibe secured by screws or bolts 20a. With this. construction, there is less danger of the gooseneck member shifting from its adjusted position once the bolts or screws have been tightened. 'I'he vertical centering adjustment of the door 8 is obtained by sliding the door endwise with respect to the two shanks Illa on the two hinges provided, While inA or out adjustment of the door to align the same with respect to the body and other door is obtainable either' by rotation of the shanks |40l relative to the door or by sliding the socket members 9dt in or out with respect totheir bolts or screws 21. The procedure in mounting the door is otherwise the same as described above with reference tov the door 8a in Fig. 4.
