UNITED STATES PATENT FFICE ROBERT ESPEY, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN SPRINGS FOR DOORS, GATES, &c.
Specication forming part of Letters Patent No. 135,192, dated January 21, 1873' To all whom it may concern:
Beit known that I, ROBERT EsPnY, of the city and county of St. Louis and State of Missouri, have invented a certain Improvement in Springs for Doors, Gates, Sto., of which the following is a specification:
This invention relates to the upper attachlnent of a spiral door-spring; and consists in the manner of preventing the adjusting-pin (to which the end of the spring is att-ached) from turning in the collar, by which it is secured to the door or side facing. This is done by means of a key fitting in seats in both the pin and collar; the collar having two key-seats a greater distance apart than those in the pin to allow the pin to be adjusted to the required nicety without cutting too many key-seats therein, as hereafter described.
Figure 1 shows the parts detached and in perspective. Fig. 2 is a side elevation of my improvement. Fig. 3 is a transverse section at' the line X X, Fig. 2.
A is the adjusting-pin, having a flattenedN portion, b, around which the upper end ofthe spring B is tightly coiled, the said spring being of the usual form, and having its lower end similarly attached to the bracket C. The head ot' the pin A has a number of holes, a, for the introduction of a lever-pin to turn the adjusting-pin in its socket. D are key-seats, that may be as numerous as the pin will allow without too much weakening the metal between the seats. I have adopted four as the maximum number that the pin may have without too much weakening the spaces d between the key-seats, and cutting away too much of the surface bearing against the socket. E is the socket bracket, having screw- F is the socket, havholes e for attachment.
ing two key-seats, f f at a distance oi" one hundred and thirty-live degrees, (the key-seats D of the pin being ninety degrees apart,) so that when one of the key-seats D is in conjunction with the key-seat f', as shown, that f will be midway between two of those D. This arrangement allows of the adjustment of the pin A to one-eighth of a turn, as may be seen by reference to Fig. 3. Supposing the key Gr to be in the key-seat f', then, if after the key has been drawn out, the pin is turned one-eighth around, one oi' the key-seats D will be brought in conjunction with the key-seat f.
It generally happens that when the spring needs adjustment one -fourth of a turn is too great an alteration, and to give more nice adjustment without injury to the bearing-surfaces d, or rendering the sides of the key-seats D too weak to stand the strain, (by narrowing the spaces d,) I have contrived my improvement. It the surfaces d are made narrow they will be liable to catch in the key-seats ff', and the pin will have no steady bearing in the socket.
I claim as my invention- The pin A and socket-bracket E F, each construct-ed with longitudinal grooves relatively spaced, to operate as described, in combination with the key G, adapted to occupy 'the key-seats successively formed by the rotation of the pin, to adjust the spring, substantially as herein set forth, for the purpose specified.
In testimony of which invention I have hereunto set my hand.
ROBERT ESPEY.
