BOLSTER-SPRING FOR WAGONS.

SPECIFICATION forming part or Letters Patent No. 399,838, dated March 19, 1889.

Application filed May 21, 1888. Serial No. 274,503. (No model.)

To all whom t may con/067%:

Be it known that I, EDWARD CLIFF, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Deister-Springs for Vehicles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the same class of bolstersprings in which are included the springs shown in my patents, Nos. 376,857 and 382,137, dated, respectively, January 24,1888, and May l, 1888.

My present invention consists in a simpler construction of the spring and means for securing the same to the bolster and body-supporting cross-bar; and the invention also consists in improved devices connected to the said cross-bar for affording better bearings for the same on the body of the vehicle and more effectually preventing` the cross-bar from tilting, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figures l and 2 are top plan views of bolster-springs embodying my improvements. Fig. is a side view of the same with the body-supporting bar mounted on the spring. Fig. a is an inverted plan view of a section of the vehicle-body,

showing the position of the body-supporting bar. Fig. 5 is an inverted plan view of the shoe or plate attached to the end of the bodysupporting bar. Fig. 6 is a vertical transverse section on line as 1r, Fig. and Fig. 7 is a transverse section on line y y, Fig. l.

Similar letters of reference indicate corresponding parts.

B represents the bolster; A, the body or' the vehicle, and C the body-supporting cross-bar, which is supported by springs interposed between it and the bolster at or near the ends thereof. Each of said springs I form of two separate coils, D D, disposed axially vertically at opposite sides of the bolster and supported at their bases on said bolster, and having their upper ends underneath the body-supporting cross-bar C and rigidly secured thereto. The attachment of said coil-springsl prefer to make in the following manner: Across the top of the bolster I place a hanger, a, which projects at opposite sides of the bolster and is formed with eyes a a, standing' with their planes vertically and at right angles to the sides of the bolster and abutting against the sa1ne,so as to sustain the hanger laterally.

Each ofthe coil-springs D is formed individually at its base with an eye, b, which stands with its plane vertically and parallel with the side of the bolster and is linked in one of the eyes a', and thus affords an oscillatory support for the spring, such support being essential to obviate torsion of the spring when subjected to a load. rlhe upper end of each coil D is formed individually with an eye, c,wliich stands with its plane horizontally underneath the body-supporting cross-bar-C, to which it is rigidly attached by bolts ZZ, passing' through said eyes and through the said cross-bar at opposite sides of the longitudinal central line of the latter.

To the under side of the body A of lumberwagons are usually attached transversely two cleats, 7L 7L, in such positions that when the body rests directly on the bolster B said cleats are respectively at the `front and rear of said bolster, and thus `prevent the body from sliding longitudinally thereon.

Inasmuch as the bolsters of different wagons vary in width, the spaces between the cleats 7L 7L on the bodies of said wagons likewise differ in width. These variations often occasion much inconvenience in iitting between the said cleats the body-supporting bar with which the bolster-spring is placed on the market- To obviate this defect I make the bar O suficiently narrow to allow it to enter between cleats h 71, placed a minimum distance apart; and in order to provide it with proper bearings on the under side of the body, so as to prevent said bar from tilting, I secure to the under side of each end of the bar a metallic shoe or plate, P, which is formed with ears e e, by which it embraces the front and rear of the usual stake, t, and also with supportingbrackets ff, projecting from the front and rear of the plate and bearing again st the under side of the body. Said plateI also utilize for bearings for the upper ends of the coil-sprin gs D D by providing said plate with holes for the passage of bolts ZZ at opposite sides of the longitudinal central line of the plate and forming the under side of the plate IOO with sockets t' #j for the reception of the eyes c c of the springs. The boltsl passing vertically through said eyes an d through the plate P and bar C at the points specied, firmly unite said parts and afford for the springs bearings near the edges of the bar C, and thus properly support the same,

Having described my inventionvhat I claim as new, and desire to secure by Letters Patent, 1S-d l. In combination with the bolster B and bar C, two separate coil-springs disposed axially vertically at opposite sides of the bolster and formed individually with bearings at opposite ends.

2. In combination with the bolster B and bar C, the coils D D, disposed axially vertically at opposite sides of the bolster, separate from each other, and supported on thebolster, and form ed individually at their upper ends with eyes c c, disposed with their planes horizontally, and the plate P, provided with bolt-holes at opposite sides of its longitudinal central line and formed with sockets M' for the eyes c c of the coils, substantially as described and shown.

In testimony whereof l have hereunto signed my name, in the presence of two witnesses, at Rochester, in the county of Monroe, in the State of New York, this 18th day of May, 1888.
