IMPROVED DOOR-SPRING.

HOF- The Schedule referredto in thea-e Letters Patent and making part ofthe same.

To 'whom it may concern Be it known that I, PATRICK SMITH, of Newport, Campbell county, Kentucky, have invented a new and useful Door-Spring; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this speciiication.

The subject of my invention is a metallic doorspring, of flat or other form, secured by an adjusting# bracket, constructed and applied substantially as hereinafter set forth.

Figure 1 is a perspective view of my spring in position.

Figure 2 is a side elevation of the same at right vangles to the jamb-face, the brackets being inseccommon wood-screw passing through the4 lip or ear' G,

from which. that portion which receives the strip C projects outward and downward in the manner shown, so as to cause the strip to work clear of the door and jamb in the act of opening and closing the door.

The lower bracket E is a four-sided block, traversed at right 'angles by two holes H H for a common woodscrew, which holes are preferably countersunk at each nd, and at its lower extremity by crossed notches ,essential particulars.

The upper bracket being screwed fast to vthe door, a less or greater twist is given to the spring by means of a screw-driven or other instrument, inserted in one of the notches` I I', and the bracket is then made fast to the jamb by a screw passing through one of the holes H H', which, being doubly countersunk, as shown, are equally available in. every position of the bracket.

vA spring of this kind is found to be much more lively and enduring in. its resilient qualities than the rod or wire customarily employed for that purpose, and, being fastened by simple wood-screws, is readily and cheaply applied, set up, or renewed when necessary.

The brackets D and E maybe attached in .the

manner shown, namely, the bracket D uppermost to the door, and the bracket E lowermost to the jamb,

or mayhave a reversed position.

'While describing the preferred form of my invention, I reserve the right to vary the same in non-` of the.holes H Hf may be dispensed with, and a common roundheaded screw used for attachment.

I claim herein as new and ot my invention- In combination with the spring C and gasket D, the four-sided adjusting-bracket E, constructed with notches J J and two screw-holes H H', substantially as and for the purposes set forth. A

^ In testimony of which invention, I hereunto setmy hand. v

PATRICK SMITH.
