ADOLPH D. GOODVIN, OF LEXINGTON, VIRGINIA, ASSIGNOR I`O DAVID G.

BOWYER, OF SAME PLAGE.

DOOR-CLOSER.

SPECIFICATION forming part of Letters Patent No. 346,742, dated August 3, 1886.

Application filed February 26,1886. Serial No. 193,297. (No model.)

back when opened beyond the llimits of such angle, and the objects are to construct a doorr closer ofthe kind named which can be cheaply made and readily applied in operative position, and which is certa-in, positive, and efficient in action; and, second, to provide a device for the purpose named which may be 2o readily disconnected and as readily connected in operative combination.

Myinvention,therefore,consists in the novel construction and combination of parts, as will be hereinafter fully described, and especially as will be pointed out in the claim made hereto.

I have cleariy and fully illustrated my improved device in the accompanying drawings, wherein- Figure l is a perspective view thereof, showing` it in operative position on a door; and Fig. 2 is a detail View of the ball-bracket and push-bar on a larger scale than shown in Fig. l.

Iteference being had to the drawings forming a part hereof, the letter A designates the door-frame, and B the door. of any size or pattern, the door being hung` on its hinges to turn open in the direction of the side on which the closer is applied.

To the 'face of the upper piece, 1, of the frame A is secured a bracket, 2, formed or provided with lugs 3 4, having bearings formed in them. This bearing device consists, prefa5 erably, of a bracketas described; but the bearings may be made separate and fixed to the door by any suitable means. A shaft or bar, 5, is passed through the bearings in the bracket, and has the free end provided with 5o a nut or bar, G, to keep it from slipping from its bearings. That part of the shaft or bar resting in the bearings is made somewhat longer than the distance between the lugs, in order that it may have longitudinal play in both directions to relieve the strain that ZIJ These may be.

would otherwise result from being seated without this movement. The outer end of this shaft or bar 5 is bent outward, forming the levcrarm 7, on the outer end of which is secured a weight, S. Close to the point of con- So nection,betwcen the lever-arm 7 and the weight S, the lever-arm has a short bend or step, 9,

to keep the loosely swung puslrbar from slipping up on the bar of the lever-arm.'

O11 the upper piece of the door is secured 65 a bracket, 10,7 which consists of a screw-plate having projecting therefrom a vertically-arranged lug, 1l, terminating in a knob or ball, l2. This lug stands outward from the door and frame, in order that the knob shall not 7o strike against the frame. Swung on the lever-arm is the push-bar 13, having secured to its free end a socketpiece, 14, the socket of which is formed to set on and over the knob of the bracket on the door. The rim of this socket is inclined with the extended line arranged to set over the top of the ball on the bracket, substantially as shown in the drawings. The shaft or bar is arranged in its bearings, so that the weighted lever-arm 8c projects about on a line with the hinges of the door, and inclined downward somewhat, to give a better angle to the push-bar, and the push-bar inclines from the seat in the leverarm to its seat on the knob, thus giving a '85 proper push on the door at all times.

The weight on the lever-arm may be varied to suit any and all sizes, weights, and kinds .of doors swung or hinged.

If it is desired to disconnect the parts, the go socket can be lifted from the ball and left to hang from the lever-arm.

Vhat I claim as inyi11vention,and desire to secure by Letters Patent, is-

The doorlcloser herein described, comprised 91 of a bracket having bearings, a bar mounted and secured in said bearings, a weighted lever-arm arranged at an angle to said journaled bar, a push-bar having one end swung in a step or seat in the lever-arm and its free roo end formed with a socket, and a bracket having a ball or knob projected therefrom, all adapted to be used and combined substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand in the presence of two attesting witnesses.

Attest: ADOLPHUS D. GOODVIN.
