FRIEDRICH STEMMLER, OF EAST NEW YORK, N. Y.
IMPROVEMENT IN DOOR-SPRINGS.
Specification forming part of Letters Patent No. 125,995, dated April 23, 1872.
Specification describing a new and Improved Door-Sprin g, invented by FRIEDRICH STEMM- LER, ofEastNew York, in the county of Kings and State of New York.
Figure 1 represents a side view of my invention. Fig. 2 is a vertical central section of the drum and spring. Figs. 3, 4, and 5 are horizontal sections of the latter, showing the parts in different positions.
Similar letters of reference indicate corresponding parts.
This invention relates to a new means of connectin g a door with a spring for closing it from both sides; and consists in a new combination of the door-pivot with two spring-contracting plates, and with the spring and drum, in such manner that when the door is swung open to either side the spring will be contracted for shutting it as soon as released from the power opening it.
A in the drawing represents the door, hung by vertical pivots a and b in the frame B. Within the frame B is secured the drum 0, which contains a coiled spring, D, the upper pivot b passing through said drum, as shown in Fig. 2, and turning therein with the door. Upon a square part, d, of the pivot b is, within the drum, placed a plate, 6, which extends nearly to the rim of the drum, and has a projectin g lug, h, at the outer end. E is a tubir lar sleeve fitted around the pin 1), with a flange, f, at the lower end, said flange being under the spring D and above the plate 0, as shown in Fig. 2. The tube E has a projecting hook, g, fitting through a slot in the inner end of the spring.
YVhen the door'is shut the lug h of the plate e is directly between a projecting car, i, of the flange f and the outer outward-bent end j of the spring, as is clearly shown in Fig. 5. \V hen the door is opened-say, to the left, as in Fig.
L-the lug It will bear against the outer end of Having thus described my invention, what I- claim as new, and desire to secure by Letters Patent, is
The combination of the door-pivot b, spring D. and drum 0 with the plate a, sleeve E, and flange f, lug h, ear 6, and hook 7, all arranged to operate substantially as herein specified.
FRIEDRICH STEMMLER.
