To all 'whom lt may ',concern:
Be it known that I, WILLIAM GILFILLAN, of Syracuse, in the county of Onondaga, and State of New York, have invented a new and usefullmproved Door- Spring; and I do hereby declare the following to be a full, clear, and exact description thereof, suticient to enable' those skilled in thc art to which iy invention appertains to fully widerstand and use the same, rei'- erence being had to the accompanying drawings, formf specification, and in which- Figure. l is a perspective view of a door and doori'ralne, to which "my improvements are applied, parts of the door and frame being broken away, to show the mechanism, and
Figure 2 is a side view of the spring and its attachments, apart from the door. I l
My invention consists in the construction, arrange` ment, and combination of parts, as hereinafter set forth.
Similar lett-ers of reference in the drawings indicate like parts in lthe several figures.
A, in the drawings, represents a door-frame, in which the door B ishuug, by means of double-action hinges a: x, which permit the door to'open either way.
The door and frame are mortised, to receivethe plates C C, with' their attachments, composing the On the back of the plate G, near the top, a bracket or brackets are formed, to support the arn E, to which an eccentric-lever, D, is attached.
l represents the spring, connected, at its upper end, with a chain, c, secured to the lever D.
Near the lower end of the plate O, on the back, is
formed a lug, through which 'the threaded shank of a hook, a, is iitted. 'lhe lower end of the spring l is connected to this hook a.
I'rcpresents a screw-nut, fitted on to the lower end of 'the shank of hook a. By turning this nut, through an opening in the plate C,..as shown, the .tension of spring l can be regulated.
A chain, b, is attached'to the end of the arm E, said chain 'passing between two friction-rollers, F F, placed in an opening in the plate C, and allowing the door to he swung in either direction.
In the casing of the door, and opposite to the friction-rollers F F, I secure a plate, G, provided, onits rear side, with two'lugs, or ways, for the purpose of holding` the nut H. g
To this nut H, the chain, b, is attached, said chain being adjusted to the proper length by means of the screw 11,. passing through the uut H, and operated, by means of a screw-driver, through an opening, lt, in the face of plate O. l
Constructed as above described, a simple and effectivc` spring is produced for double-acting doors.
Vhat I claimas new, and desire to secure by Letters Patent, is
The plate O, with eccentric, D, and arm E; the chains, or cords b c, the spring l, and adjustable hook a,4 and nut H; all combined and arranged to operate substantially as herein described.
