DOOR-SPRING.

SPECIFICATION forming part of Letters Patent No. 369,203, dated August so, 1887.

Application filed June 27, 1887. Serial No. 242,696. (No model.)

.To all whom it may concern.-

Be it known that I, JOHN W. ODANIEL, of Clover-dale, in the county of Putnam and State of Indiana, have invented certain new and useful Improvements in Door-Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in door and gate closers; and it consists in the combination, with a stationary plate and a plate which is secured to the door, of two rods which have their outer ends loosely connected to the two plates and their inner ends made to pass through a spiral spring and attached to opposite ends of the spring, and the spring, the two plates havinga series of perforations, all of which will be more fully described hereinafter.

The object of my invention is to provide a device for keeping doors or gates closed which is simple in construction, which can be applied to gates and doors of all kinds without any change whatever, and which can be easily and quickly adjusted to any desired tension, according as it is applied to heavy or light doors or gates.

Figure 1 is a perspective of my invention applied to a door. Fig. 2 is a detail view of one of the rods.

. A represents the frame of the door, and B the door. The perforated plate 0 is preferably secured to the top of the frame A. by means of screws, as shown, and the perforated plate D to the door near its upper edge. rods E E have their outer ends bent at right angles, as shown at F, and their inner ends bifurcated, as at G.

The two Passing around the inner .ends of the two rods E E is the spiral spring H, which has its ends placed in the bifurcated ends of the rods E E, and the two rods are made sufficiently long to pass by each other and through the spiral spring, as shown.

When the door is opened, the inner ends of the two rods are forced outward and the spring extended, and when the door is releasedthe tension of the spring draws the inner ends of the two rods E E toward each other, thus causing the door or gate to close. The plates 0 D being provided with a series of perforations, it is only necessary to lift the bent door, of the two rods E and spring H, the

outer ends of the rods being bent at right angles and secured to the plates, and their inner ends passing through the spring and secured to opposite ends thereof, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN W. ODANIEL.
