Description

"tinihml time EDMUND L. MORSE, OF
ST. LOUIS', MISSOURI.
Lemma Patent No. 87,867, daad March 16, 1869.
IMPROVEMENT IN' DOOR-SPRINGS.
The Schedule referred to in these Letters Patent and making part'of the same.
To all who/ml fit may concern Be it known that I, EDMUND L. MORSE, of the city of St. Louis, in the county of St. Louis, and State of Missouri, have made certain new and usefullmprove-l ments in Door-Springs; and I do hereby-declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and t-o the letters of reference marked thereon.
' This invention relates to the use of a rubber spring,
in connection with proper lsocket and slide pieces on doors, or other hinged frames, for lkeeping closed, or rapidly closing such doors or frames after being opened. To enable thoseherein skilled to make and use my said invention, I will proceed to describe the same more fully, by reference to the accompanying Figure I as a plant Figure 2'as a front elevation;
Figure 3 as a sectional elevation; and
Figure 4 as a plan View of the rubber spring.
A represents the door-frame, tov which a door, or gate, A', is hinged, in the usual manner. In the ordinary application of my said invention, it will be used to keep the door Af closed. In its said application, the construction of said invention will be in the general manner now to be described.
I use a rubber spring,-- B, which will be formed in the hollow cylindrical outline indicated in tig. 4.
In order that said spring may. act fairlywith the sockeifpieces, (hereafter described,) I cut out of said cylinder B, -the prism b, it being the especial purpose to form a spring whose ends, b* and b2, shall have such surface as shall fairly abut against proper ribs of the socket-castings.
'It may be advantageous to increase the prism b, so that the ends b b2 fall in the dotted line x y. In all such cases, it is hereby expressed as an essential feature of this device, that both ends, b b2, shall present the same inclination, and that by the cutting of the spring B, the length thereof, measured on the inner diameter, shall not becurtailed.
In the application of said spring B, one of its ends is inserted in the socket-piece C, and the other, in the sliding socket D, generally, as indicated in figs. 1, 2, and 3.
The socket C is secured to the door-frame A by proper screws, and, to prevent its loosening, has the prong c, which penetrates the frame A.
The end, b, of the spring B, abuts against the rib c', of the said socket, and the upper and lower ribs, cz and c3, hold the spring laterally.
In orderthat the spring B may be rmly held, and to more eectnally resist its tendency to draw out and return to its original circular shape, the end of the spring is permitted to pass between the ribs c and o3,
andin order that the end edge, thus projecting, may not be'pressed out in screwing the socket O against the frame A, the rib ca is-set back from the lower face of the socket O, as indicated in fig. 3, and a space, c, is thus formed, under and behind the rib c3, for the projecting edge of the rubber.
Similarly, the other end, b?, of the spring B, is run into the socket D, abutting against the end rib d, and
held laterally bythe upper and lower ribs, d* and d2.
Here, also, a slot is left between 'the ribs d2 and d, to permit the end of the rubber to pass through` and thus firmly clamp the spring against itswithdrawal.
The sides of said socket D form the horns da, which have, at or near their ends, the pins, or rollers d.
In the application of the said parts, the rollers, or pins d* may run on proper raised ways on the door A', but I deem it more advisable to specially arrange the guide-casting E for this purpose, said casting being secured by prongs and screws to the door A', and ar ranged with side ways e, the ends c whereof are raised, so as to prevent the 4pins d*l from withdrawing from the ways e. Said ways e will be somewhat inclined, as indicated in iig. 3, so that the pins d* will run up and off from the door-face, as it is opened, and thus increase' the leverage of resistance. l
It will be seen thatin inserting the spring B in -the sockets G and D, it has been straightened, and said straightening is exerted against the resistance of the material. In the position of its application said spring, B, therefore, exerts great pressure to force the socketD against the door and vguide-piece E, and thus the device, here described, vac ts to close the door, as desired. Moreover', owing to the formation of the ends b b to correspond to the inclination of the abutment-ribs c and d, ofthe sockets O and D, the pressure of said spring is fairly economized and made effective. And, lastly,by the method of retaining the ends of said spring between the socket-ribs, the spring is prevented from withdrawing, as is the case in similar devices.
Having thus fully described my invention,
1 The rubber' spring B, having the bearings b b2, when combined with the sockets O D, all constructed and arranged as described, for the purpose set forth.
2. The spring B, sockets G and D, and ways E, when combined and operated as described, for the purpose set forth.
In witness of said invention,` I have hereunto set my hand, in the presence of'- E. L. MORSE.
