EDWARD L. HOFFMANN, OF BUFFALO, NEW YORK.

CARRIAGE-DOOR HINGE.

SPECIFICATION forming part of Letters Patent N 0. 577,983, dated March 2, 1897.

Application filed October 19, 1896.

To all whom it may concern:

Be it known that I, EDWARD L. HOFFMANN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Hinges for Carriage-Doors, of which the following is a specification.

This invention relates more particularly to that class of hinges for coach-doors in which the member of the hinge attached to the door is provided with an angular or elbow-shaped arm which passes through a slot in the fixed member of the hinge and which is pivoted to a bracket of the fixed member.

The object of my invention is to provide such hinges with a simple stop device which reliably limits the opening movement of the door and which'is not liable to break or get out of order.

In the accompanying drawings, Figure 1 is a horizontal section of a coach-door provided with my improved hinge, showing the door closed. Fig. 2 is a similar section showing the door open. Fig. 3 is a detached perspective view of the hinge.

Like letters of reference refer to like parts in the several figures.

A A represent the usual upright pillars of a carriage-body, which form the sides of the door-opening, and B is the door. 0 is the attaching or base plate of the fixed hinge member, which is secured to the inner face of the pillar A, and cl is the bracket project ing from the rear side thereof and carrying the usual upright pivot or pintle cl, the pillar being recessed in the usual manner to receive this bracket. E is the base-plate of the mo vable hinge member, secured to the coach-door, and F the angular arm project-ing horizontally from the face of said base-plate. This arm extends through a horizontal slot d formed in the base-plate O of the fixed hinge member, and is provided at its outer end with the usual eye f, which receives the pivot or pintle d. g is the usual uprightweb or abutment extending upwardly from the outer edge of the bracket d. All of these parts are of the usual and well-known construction and form no part of my invention.

H is an elastic stop which limits the open- 1ng movement of the coach-door, so as to prevent the same from swinging against the rear Serial No. 609,260. (No model.)

wheel on the same side of the coach. This stop preferably consists of an approximately U-shaped spring of flat steel, which extends around the eye of the arm F and. has its inner rear branch secured to the rear side of said arm by screws h or other suitable means, while its front branch 72. is free, so as to form a spring tongue. This spring-tongue is so arranged that in opening the door the tongue comes in contact with the inner side of the abutment g before the door reaches a position in which its outer side comes in contact with the rear wheel, as shown in Figs. 2 and 8, thereby preventing marring of the door. The door is usually provided with two hinges, and the stop-springs are made so stiff that their combined resistance is suificient to arrest the opening movement of the door before the angular arm F reaches the abutment g, thereby avoiding the straining or springing of the door, which is liable to occur when the angular arm strikes against said abutment. As the stop-is elastic or yielding, it forms a cushion, which prevents all jarring or straining of the door, and the cracking of the paint or enamel on the door, liable to result from the concussion of the parts of the hinge, is therefore obviated. Myim proved stop-spring dispenses with the usual stop-strap and overcomes the disadvantages resulting from the stretching of such straps, and as the spring is applied to the inner portion of the angular arm of the hinge it is hidden from View, thus forming a more sightly construction. When the door is closed, the spring-tongue recedes from the abutment g, as shown in Fig. 1.

By securing the stop-spring to the rear side of the angular arm and extending it loosely around the eye of said arm, as shown, fiexion of the spring takes place from its point of attachment to its free end, thus rendering the same very elastic.

I claim as my invention 1. The combination with a fixed hinge member or leaf having a transverse slot and a bracket projecting rearwardly from said leaf, of a movable hinge member or leaf having an angular arm extending through the slot of the fixed member and pivoted at its inner end to said bracket and a stop-spring carried by the inner portion of said angular arm and arranged on the front side thereof, said spring being arranged to come in contact With said fixed leaf in the open position of the hinge, substantially as set forth.

2. The combination with a fixed hinge member or leaf provided with a transverse slot, a bracket projecting rearwardly from said leaf and carrying an upright pintle and a Web or abutment arranged at the outer edge of said slot, of a movable hinge member or leaf having an angular arm extending through the slot of said fixed leaf an d provided at its inner end with an eye journaled on said pintle and a U shaped spring extending around the eye
