Description

limite STATES JOHN A. MOHR, OF MANCHESTER, IOWA.

DOOR-SPRING.

SPECIFICATION forming part of Letters Patent No. 236,689, dated January 18, 1881.

Application iiled September 20, 1880. (No model.)

To all whom t may concern:

Be it known that I, JOHN A. MOHR,of Manchester, in the county of Delaware and State ot' Iowa, have invented an Improvement in Door-Swings' and I hereby declare the following to be a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

rlhis invention consists in the combination of a plate-spring of peculiar form with eertain bearing ears or iiaps, and with certain securing-pins, by means ot' which a simple spring is obtained, which can be produced at a "ery low cost.

In the drawings, Figure l represents an isometric view ot' myimproved spring applied to a door, the latter being represented in its closed position; Fig. 2, a similar view with the door in its open position, and Figs. 3 and 4 side and end elevations of the spring detached.

To enable others skilled in the art to make my improved sprin g, I will proceed to describe fully the construction ot' the saine.

A, Figs. l and 2, represents the jainb ot the door, and a the door itself.

B represents a spring, consisting of a plate ot sheet-steel wider at the central portion than the ends, which is bent into U-shapeform, as shown in Fig. 4, and is set in that position and properly tempered to give it the requisite elasticity.

I) b, Figs. 3 and 4, represent eyes formed in the ends of the plate by properly bending the same, and b', Fig. 3, a central recess between the eyes.

O O represent bearing ears or iiaps, each ot' which is provided with a proper screw-hole, by means of which the sameis properly screwed to the jalnb or door, and with a projection, o, having an eye, o', as shown, which projection is adapted to extend into the recess b', as shown in Fig. 3.

D, Fig. 4, represents a securing-pin, which such points that the spring, when in its normal position, will act to keep the door closed.

The operation is substantially as follows: By the ordinary opening ot' the door the end of the spring upon the door is drawn away from that upon the jamb against the resistance ot' the spring. When, consequently, the door is released, the same is closed by the necessary reaction. When the door is opened wide, as shown in Fig. 2, the tendency of the spring, it will be observed, is to keep it open.

Some ot the advantages ofthe described construction are as follows: By constructing the spring-plate in the form shownthat is, with the widest part in the center-the material is disposed in the best manner-thatis, the greater part et' the same is located at the point ot' greatest strain.

The construction of' the spring, as a whole, is very simple, and it can be produced at very low cost.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

rIhe door-spring described, consisting of the plate-spring B, having the eyes b formed integral therewith, the bearing ears or iiaps O, having the eye-projection o, and the securingpins D, uniting the flaps and plate together, arranged and attached in the manner set forth.

This specification signed and witnessed this 16th day of September, 1880.

JOHN A. MOHR.
