Application led January 27, 1913.' Serial No. 744,449.

To all whom t may concern.' 4

Be it known that I, J AMES D. STOAKES, a citizen of the United States of America, residing at Detroit, inthe county of Wayne and lState of Michigan, have invented certain new and useful Improvements in Hinges, of which the followlng is a specification, reference being had therein to the accompanying drawings.

The invention relates to hinges and has among the objects thereof to provide a construction of concealed hinge which will permit of varying movements of the inner edge of the door at the 'points where the hinges are secured, but will nevertheless effect a movement of the top and bottom edges of the door in substantially, horizontal planes;v and 'further to provide such a hinge that is exceedingly compact when closed. y

Otherobjects of the invention will more fully hereinafter appear.

The invention resides in the novel construction, arrangement and combination of parts as herein described and claimed.

As my improved construction of hinge is particularly adapted to automobiles, I will illustrate and describe the same as applied to the door of a motor vehicle.

In the drawings, Figure 1 is a fragmentary, perspective view of an automobile body and door, with my improved construcvtion of hinge applied thereto; Fig. 2 is a similar view of the hinge open; Fig. 3 is a view looking in the opposite direction from Fig. 2; Fig. 4 'is a view of the hinge closed;

and Fig. 5 is a, Section on the line w-m of Fig. 4. v

A designates the door and B the casing.'

C and D are .the hinges connecting the door and casing. In the usual construction of automobile body the body side and door are curved inward adjacent the bottom. Therefore, in order for the top and bottom edges of the door to 'swing in horizontal planes the hinge D must provide for a greater movement than the hinge C. With my improved construction this may be readily accomplished by merely increasing the length of the hinge leaves, as will more fully hereinafter ap ear.

of an automobile As shown, the hinge C is composed ofl plates E and complementary leaves F G, the leaves each havlng eyes H at their outer closed.

ends adapted to aline with knuckles I on the leaves and pivotally connected thereto by a pin J. The inner ends of the leaves also are provided with` inter-engaging knuckles K andL pivotally connected by a pintle M. The pivot pins J are positioned at an angle to the axis about which' the door turns, while the pintle M is transverse to the pivot pins. By so arranging the pivot pins and the pintle the door is caused to swing inan arc,

though the vertical axis about which the door turns shifts laterally during movement of the door and the top and bottom edges of the door are maintained in horizontal planes. That is, the hinges prevent sagging of the door in the opening movement of the latter. When the hinge is lclosed the pintle is at an angle to the pivot pins, as shown in Figs. 4 and 5, making the hinge parts readily responsive to but a slight-'stress in opening the door. l

It will be noted upon reference to Figs. 2 and 3 that the knuckles I of the plates are off-set toward the inner sides of the latter, providing flat outer faces N for engaging the edges of the door and casing, while the eyes H and the knuckles K and L r'e'sopositioned as to permit the faces C of the leaves to lie flat against the inner sides P of the plates and to allow Q of the leaves to 'abut whenV the 'hinge is Preferably the plates are provided with flanges R which form therewith a housing for receiving the leaves. l

In applying the hinge to the door and casing the adjacent edgesS T thereof are recessed as indicated-at U to receive the plates.

The latter are then secured in place by suitable screws V passing through apertures W in the .plates and when the hinge is attached the outer'edges of the flanges lie in the plane of the door or casing edge to which it is secured. By this arrangement it is merely necessary to recess the edges of the door and body to a depth equal to the height of the flanges R. Preferably the ends as X of the recesses for one of the hinges are positioned to form stops for the leaves during opening of the door so as to prevent the leaves from passing into the' plane of the pivot pins. This avoids the pivot pins and pintle from reaching 'dead center, so to speak.

As before stated, the hinge D must prothe opposite faces vide for a greater movement than the hinge C. This is accomplished by increasing the length ofthe leaves. The relation of the pivot pins and pintle however, remain the same. In order to provide housings for the leaves it is f course, necessary to proportion the length ofthe plates to correspond to the increase in the length of the leaves.

What I claim as my invention is: A l. A hinge, comprising plates and complementary leaves pivoted together at their inner ends and pivotally connected to the plates atl their outer ends at an angle to the longitudinal axis about which the plates move relative to each other, the inner ends of the leaves being arranged intermediate the opposite ends of the plates. y

2. A hinge, comprising plates and complementary leaves pivotally connected to the plates at their outer ends and pivoted together at their inner ends, the axis of the last-mentioned pivot being at an angle to the longitudinal axis about which the plates move relative to each other, the inner ends ofthe leaves being arranged intermedia-te the opposite ends of the plates.

3. A hinge, comprising plates and complementary leaves pivotally connected to the plates at their outer ends at an angle to the longitudinal axis about .which the plates lmove relative to each other, said leaves being pivoted together at their inner ends, the axis of the last-mentioned pivot being transverse to said longitudinal axis, the inner ends of the leaves being arranged intermediate the opposite ends of the plates.

4. A hinge, comprising plates and com.- plementary leaves pivotally connected to the plates at their outer ends at an angle to the longitudinal axis about which the plates move relative to each other, said leaves being pivoted together at their inner ends, the axis of the last-mentioned pivot being transverse to said longitudinal axis and also transverse to the pivotal connections between the plates and the leaves, the inner ends of the leaves being arranged intermediate the opposite ends of the plates.

5. A' hinge, comprising plates and complementary leaves pivoted at their outer endsto the plates, each pivotal connection between the leaf and its corresponding plate being olf-set inward from the outer face of the plate, said leaves being pivoted together at their inner ends, each of said pivotal connections being at an angle to the longitudinal axis about which the plates move relative to each other.

6. A hinge, comprising plates and complementary leaves pivoted together at'their inner ends and pivotally connected to the plates at their outer ends, the pivotal connection between each leaf and its corresponding plate being ott-set inward from the outer face of the plate and each of the latter having a flange extending therearound cooperating with the plate to form a housing for the leaf in the closed position of the hinge, the pivotal connection being transverse to the longitudinal axis about which the plates move relative to each other.

In testimony whereof I affix my signature in presence of two witnesses.
