`b. gis a plate, secured to the door.
UNITED STATES PATENT GFFICE.
GEORGE E. SUTPHEN, OF AURORA, ILLINOIS.
IMPROVEMENT IN DOORSPRINGS.
Specification forming part of Letters Patent No. 187,738, dated February 27, 1877; application filed June 19, 1876.
To all whom't't may concern:
Be it known that 1, GEORGE E ASUTPHEN,
ofAurora, Kane county, State of Illinois, have invented new and useful Improvements in lDoor-Springs, of which the following is a full description, reference being had to the accompanying drawings, invwhich- Figure lis an elevation, showing the device attached to a door; Figs. 2, 3, 4, 5, and 6, details, Fig. 4 being a top view of the plate g, and Fig. 5 a top View ofthe leverf; Fig. 7, a modification.
This invention relates to door-springs; and consists in a plate provided with a projection or catch, and a lever or rod having a projection or catch, combined with a spring, as will be hereinafter more fully described.
In the drawings, A represents the doorframe, and B the door with my device applied thereto. a is a coilfspring. b is a rod, which passes through the spring, and its ends extend beyond the ends ot' the spring. c d are two brackets, each provided with an ear,e, through which the rod b passes, and in which it can rotate. Both ends of the rod b are made manysided instead of round-as represented, these ends are six-sidedand the upper end extends above the bracket c, andthe lower end below the bracket d. One of the brackets, d, as shown, is provided upon the inside with a recess,j, to receive one end ofthe coil-spring a. The other end of this-spring is permanently secured to the rod b. fis a rod or lever, one end of which has amany sided opening,j, corresponding to the Jr'orm ot' the end of the rod h is a catch or projection onl the plate g. t' is a corresponding projection on, or notch in, the leverf, to engage with the catch h.
In use, the brackets are to be secured to the door-frame, thereby holding the spring al and rod b in place, the spring being between the two brackets. In this position the spring is neutral. By means of a socket-wrench ap- When the door is opened wide, the projection or catch i of the leverfwill slide over and engage with the catch h upon the plate g, and hold the door open.
It' the projection h or catch t' be made beveling, the door can be closed by using a gentle force; but if they are made straight it will be necessary to lift the end ot' the lever for this purpose.
The door may be held open by means of a hook secured to the plate g, as shown iu Fig. 7 5 but in this case it will be necessaryto remove the leverf, and give the proper tension by turning the rod b. from right to left, and then replace the lever. sion of the spring will hold the door open, and it will be necessary to close it by the use of force.
The tension of the spring can be adjusted at any time, as may be desired, by means of the wrench.
The spring can .be used either with right or 'left handed doors Without any change.
What I claim as new, and desire to secure by Letters Patent, is as follows:
In a doom-spring, the plate g, provided with a projection or catch, h, and a lever or rod, j", provided with a projection or notch, t', in combination with the spring a, substantially as and for the purpose specified.
