RICHARD vosE, 0E NEW YORK, N. Y.
' 1 IMPROVED CAR-SPRING.
Specification forming part of Letters Patent No. 26,723, dated January 3, 1860; Reissue No. 1,194. dated June 4,
T 0 all whom it may concern:
Beit known that 1, RICHARD VosE, of the city, county, and State of New York, have invented a new and Improved Car Spring; and
I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, in W' ich- Figure l is a view of one end of my improved car-spring, Fig. 2, a longitudinal section in the line xx of Fig. 1, and Fig. 3 a transverse section in the line y y of Fig. 2.
It is well known that if disks of india-rubber are brought into direct contact with plates of iron in the constructionv of v'car-springs the said rubber disks will soon be greatly injured by the chemical influence exerted by the oxidation ot' the iron. It is also well known that if an indiarubber spring be exposed to violent concussions when compressed between unyielding surfaces the periphery of said spi-ing will soon show numerous fractures, a sure precursor of its utter failure to any lon ger serve the purpose of a spring.
To remedy the aforesaid defects in indiarubber car-springs is the object of my present invention, and this I accomplish by placing each disk or layer of india-rubber in a carspring between interposed disks or layers of some ibrous material, snch as feltin g or some other eompressible article of a similar nature.
The cavity within the ange e of eachinetallic cap or end plate, E, of my improved oar-spring is of sufiicient depth to first receive a fibrous disk, B, and then leave a sutlicient l nnappropriated portion of said cavity for the reception and retention of one`of the indiarubber disks, A, of said spring.
The brous disks B, which are placed between the faces of the india-rubber disks of my improved' car-spring, are surrounded by internally-grooved metallic rings (l, which embrace the peripheries of the said fibrous disks 'and protect the same from the action of moistnre, while the flanges which project from the upper and lower sides of said rings receive the peripherics of the faces of the india-rnbber disks and retain the same in their proper positions, as shown in Fig. 2.
Having thus fully described my improvedl ear-spring, what I claim therein as my invention, and desire to secure by Letters Patent, is-
1. Placing the india-rubber disks of said spring between interposed disks formed of some fibrous material, substantially in the manner and for the purpose herein set forth.
2. vWhen the india-rubber disks in a carspring are placed between interposed disks formed of some fibrous material, combining internally-grooved metallic rings U C with the periph eries of said disks, substantially in the manner and for the purpose herein set forth.
rlhe above specification of my improved car-spring signed and witnessed this 5th day of June, 1860.
