Application flleg. November 9, 1914. Serial No. $71,057.

To all whom it may concern Be it known that I, HARRYA. LoMAsoiv, a

"citizen of the United States of America, re-

\ bile bodies.

It is one of the objects of the invention to provide a construction in which the door section of the hinge is readily detachable from the body section.

It is a furtheypobject to carry the load and principal stresses by integral portions of the hinge members.

With these and other objects in view the invention comprises various features of construction as hereinafter set forth.

In the drawings: Figure 1 is a perspective view showing the door and body sec- I tions detached but ready for engagement;

Fig. 2 is a horizontal section through the hinge in closed position of the door; and Fig. 3 is a similar view in the open position of the door and showing the( keeper released to permit of detachment.

A is the door member andB is the body or frame member of the hinge. The latter is preferably formed of a flat bar which is bent with the U-shaped portions G therein, which form the recesses for the engagement of the door member. The connecting portion of the bar D intermediate these U-shaped portions is secured by suitable means such as the, screws E to the inner face of the vehicle body, and there are preferably also extensions D beyond the U-shaped portions similarly secured by screws E. Y

F is the pivot pin which extends across the recess intermediate the parallel sides of the Ll-shaped portions C.

The door member A is formed with a securing bar G adapted to be attached to the inside ,of the door by suitable means such as the screws 11. Integral with this securing portion G are curved arm portions I, preferably pressed into a channel-shaped cross section and provided at their outer ends with the hooked bearings J for engaging the pivot pin F. The arrangement is such that when the door is in open position the arms I may be inserted into the recesses within a the U-sha ed portions 0 and the hooked bearings engaged with the pins F. To secure the parts in this engagement keepers K are attached to the arms I to close the hook as shown in Fig. 2. The keepers K are necessarily arranged in a position difficult of access when the members A and B are in positions for enga ement. -I have therefore provided means or engaging and disengaging the keepers, operable from the exposed side. As shown, this comprises a pivot pin L for attaching the shank of the keeper within the channel portion of the arm I, and.

so that its outer end K which engages the pivot F, is free to move.

M is a screw arranged between the pivots L and F and clamping the keeper to the arm I, said screw having itshead M on the exposed face of the arm I.

N is. a spring for automatically moving the free end of the keeper away from the pivot F when released by the screw M, and O is a lug projecting from an extension 0' vof the keeper beyond the pin L, said lug passing through an aperture P in the arm I so as to be operable from the outside of said arm.

The construction just described is such that when the screw M is disengaged the spring N will hold the keeper in the position shown in Fig. 3, where it is separated from the hooked bearing K a suflicient distance to permit of engaging or disengaging the arms I from the pin F. When the hooks J are engaged with the pin F, as shown in Fig. 3, by pressing upon the lug O projecting through the recess P the keeper K may be moved inward against the tension of the spring N, so as to bring the threaded aperture for the screw M in registration with the aperture for said screw which is in the arm L This permits the operator to engage the screw and clamp the keeper in position. On the other hand, when the hinge is to be detached.

it is only necessary to remove the screws M, whereupon the spring N will separate the keeper from the hook J and permit the operator 'to disengage the latter from the pin F. Thus the door may be quickly and easily removed or replaced and when in normal position the load and principal stresses are carried through the integral arms I and not by the attached keeper.

What I claim as my invention is 1. A hinge comprising a recessed member having a pivot pin in the recess, ating member provided with an arm for projecting into said recess and having a bearing on said pin, and a keeper attached to said integral arm for preventing disengagement of the same from said pin.

2. A hinge comprising a recessed member having a pivot pin extending across the recess, a cooperating member having a projecting arm for insertion in said recess, with, a hooked bearing at the end of said arm for engaging said pin, and a keeper detachably clamped to said arm for preventing disengagement of the pin from said hooked bearing.

3. A hinge comprising a recessed member having a pivot pin extending across the recess, a cooperating member provided with a projecting arm for insertion in said recess and having a hooked bearing at its end for engaging said pivot pin, a keeper'for holding said pivot pin in engagement with said hooked bearing arranged upon the side of said arm which is concealed in the engaging position of the parts, and means for clamping and unclamping said keeper operable from the exposed side 'of said arm.

4. A hinge-comprising a recessed member having a pivot pin extending across the recess, of a cooperating member having a projecting bent arm for insertion in said recess with a hooked bearing at the end of said arm for engagement w1th said pin, akeeper for retaining said hooked bearing in engagement with said pin arranged on the inner side of the bent arm and pivotally attached thereto, a spring for yieldably holding said keeper in a position providing clearance for engaging said hooked bearing with said pivot pin, and a clamping screw for holding, said keeper in engagement with said pin operable from the exposed face of said bent arm. a

5. A hinge comprising a recessed member having a pivot pin extending across the rea cooperintegral cess, a cooperating member provided with a pro ecting bent arm of channel shaped cross section and having a hooked bearin :at its outer end for engagement with sai pivot pin withinsaid recess, a keeper pivotally attached to said arm within the channel thereof for holding said hooked bearing in engagement with said pin, a spring for normally holding said keeper in a position to permit engagement with said pivot pin, means operable from the exposed side of said bent arm for moving said keeper into its locking position and a clamping screw engageable from the exposed side of said arm for retaining the keeper'in clamping position.

6. hinge comprising a recessed member having a pivot pin extending across the recess, a cooperating member having an integral bent'a-rm for insertion in said recess, one end of the arm being provided with a hooked bearing for engagement with said pivot pin and the intermediate portion of said arm being of a channel-shaped cross section, a keeper 'for holding said hooked bearing in engagement with said pivot pin pivotally secured within the-channel of said arm, a clamping screw intermediate the point of pivotal attachment of said keeper and said pivot pin for holding said keeper in retaining position, a spring for retracting said keeper when released by said clamping screw, and a lug projecting from said keeper through a recess in said arm on the opposite side of the point of pivotal attachment of the keeper, for moving the latter into position for engagement of the clamping screw.

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

HARRY A." LOMA'SON.
