DOOR-STRIP.

SPECIFICATION forming part of Letters Patent No. 330,563, dated November 17,1885.

(No model.)

To all whom it may concern:

Be it known that I, WILLIAM CLARK, of Lincoln, in .the county of Lancaster and State of Nebraska, have invented a new and Improved Door-Strip, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved door-strip, which automatically closes the space between the bottom edge of the door and the top of the sill, and which strip is raised automatically when the door is opened.

The invention consists in the combination, with a door, of a strip held on the bottom of the same, and provided at the top edge with spring-arms formed on the strip, of which arms one is held in a staple at the free edge of the door, and the other is provided with a screw for adjusting the door-strip.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal elevation of my improved door-strip, the same being raised, the outer strip being removed. Fig. 2 is a similar view showing it lowered. Fig. 3 is a sectional plan view on the line as m, Fig. 1. Fig. 4 is a cross-sectional view on the line yy, Fig. 2.

A strip, A,having itsinner surface recessed, is secured at its top edge on the front of the door B, the bottom of the said strip being flush with the bottom edge of the door. In the recess between the front of the door and the back of the strip A, a strip or board, 0, is held to move vertically, the bottom edge of the said board or strip being beveled or otherwise shaped to fit on the top of the sill D. A short distance below the top edge two sawcuts, E, are made in the board 0, which extend from the ends to near the middle, and are parallel with the top edge of the strip, thus forming two spring-arms, F. The free end of that spring-arm F at the free edge of the door is held in astaple, G, on the front surface of the door, and the free end of the other arm rests on a pin, G, and a screw, H, which can be adjusted to project a greater or less distance, is held in the end of the said arm F. When the door is open, thespring-arms F are in their normal position, and the strip 0 is held drawn up to the same, and is thereby raised from the sill. When the door is closed, the screw H strikes the jamb J, whereby the corresponding arm is pressed inward and both arms pressed downward at the middle, whereby the strip 0 is pressed down upon the sill D. When the door is opened again the arms F spring upward and raise the strip 0, so as to clear the-sill. The screw H can be adjusted so as to press down the strip 0 a greater or less distance.

The strip is very simple in construction, strong and durable.

I am aware that a bar having a rubber secured in its lower edge, and provided with springs having apertures in their ends for the reception of pins on the casing, one of the said springs being acted upon bya pin attached to the casing for pressing the said bar downward, is old, and I therefore do not claim such invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a door, of a strip held vertically movable on the bottom of the door, which strip is provided at its top with two spring-arms formed out of the top part of the said strip, substantially as herein shown and described.

2. The combination, with the door B, of the strip 0, having spring-arms F formed on its the arm F at the free edge of the door, substantially as herein shown and described.

3. The combination, with the door B, of the strip 0, having spring-arms F formed on the top of the strip, the staple G, and of the screw H, substantially as herein shown and described.
