Description
' f i.. were. "t wird .gister @anni @time ...We NW PERRY e. GARDINER, oF NEW YORK, N. Y.
Letters Patent-No. 84,688, dated December 8, 1868.
IMIPROVED CAR-SPRING.
or-f-- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
the outside of which latter three or' more India-rubber solid -springs are placed, the whole enclosed in a snitable casing, and operated by a plunger acting upon the centralIndia-rubber spring.
Figure I is a longitudinal section of the spring, at the lineC D of Fig. II, and
Figure II is a horizontal section ofthe same, at the line A B of Fig. I.
Similar letters represent similar parts.
In the accompanying drawings- E isla casing, made with four circular recesses, F, and secured to and closed by a bottom or sole-plate, G.
In the centre of this casingE, a solid, o'r nearly solid, strong India-rubber spring, H, is placed, resting upon a concave projection, a, provided on the sole-plate G.
Around thisIndia-rubber central spring H, two, three, or'more dat steelpsprings, n, m, and w, are placed, arranged in such a manner that the cut in each spring shall come opposite, Iornearly so` to the. cut of the spring situated inside ofthe other. 4
The interior or central spring n is made to enclose the central India-rubber spring H tight; and in the same manner the spring on tits tight around the spring n, and the spring w, tits tight around the spring fm..
These springs, n, m, and w, are made of such a length as to correspond with the whole `depth of the interior of the casing E, and act, at the same time, as a guide for the plunger P.
Against the outside of the outer spring w, and the interior surface of the recesses F, made in the casing E, solid India-rubber springs J are placed, itt-ingtight into this space, and acting against the exterior of theiiat steel springs in such a manner as to keep the said springs tight against the internal and central India-rubber spring H.
These India-rubber springs J are made considerably shorter than the internal depth of casing E, to allow for their expansion lengthwise, when the Aspring is in action.
Upon the top of the central India-rubber spring H, a plunger, P, is made to act, providedavith a projecting bolt, Q, passing through the top of the casing E.
The load acting upon this bolt Q will cause the plunger P to compress the central India-rubber spring H lengthwise, which latter being confined within thek steel-spring rings n, m, and 1c, will cause to expand the said steel-spring rings, and which, in their turn, act
upon the India-rubber springs J laterally, producing,
bythe united strength of all these springs, avery strong and powerful spring, by a Very small expenditure of material.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
The arrangement of an India-rubber spring, H, surrounded by steel-spring rings, n., m, and fw, and Indiarubber springs J, enclosed in a suitable casing, E, in combination with a plunger, P, acting upon the central India-rubber spring H, the whole being combined and operating together, in the manner and for the purpose substantially as described.
