TURNING-GEAR FoR VEHICLE-S.

SPECIFICATION forming part of Letters Patent No. 252,434, dated January 17, 1882.

Application filed June 21,1881. (Nomodell) To all whom it may coiwerni Be it known that I, PETER B. CUNNINGHAM, a citizen of the United States,residin g at Allentown, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Improvement in Turning-Gear for Vehicles, which improvement is fully set forthin thefollowing specification and accompanying drawings, in which Figure 1 is a side elevation of the turninggearembodying myinvention. Fig. 2 is a similiar view, some of the parts being reversed. Fig. 3 is a horizontal section in line mm, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

My inventionconsists in constructing the turning portions of the axle each of a journal, laterally or inwardly extending bosses, and a perpendicular web which projects outwardly from thebosses and is connected to the journal.

It alsoconsists in constructing the stationary portions of the axle each of upper and lower parts separate from each other, each i I part. being formed ofa boss, an inwardly-pro jecting web, and-an inwardly-projectingironor flange, the ends of the stationary axle being bolted to the irons or flanges of said upper and lower parts of the stationary portions. By these constructions the journals are firmly connected and sustained, spreading of the gear is avoided, and the parts of the stationary portion are applicable and removable independently of each other, being independent of the stationary axle, and the entire gear'isstrong, durable, serviceable, and inexpensive.

It also consists in rendering the stationary portion of the gear reversible, whereby it is adapted for both high and low-down springs and bodies of vehicles.

Referring to the drawings, A represents the stationary portion of the axle of a coach or vehicle, and B the turning portion or journal th ereof,which latter is formed of suitable metal, with which is cast or wrought a perpendicular web, G,"at whose ends are inwardly-projecting bosses D D, having vertical openings or iron, H, which is bolted or otherwise firmly. connected to the under side of the stationary portion of the axle, which may be wood or metal. To the upper; side of said portion A is bolted or otherwise firmly connected a flange or iron, H, with which is formed a web, F, the latter carrying an outwardly-projecting boss, G, through which the boltis E passed,itnow being noticed that the parts A Bof the gear are connected by said bolt E, and the webs are parallel.

It will be seen that the bossesD D are within the bosses G G, or in the same rightline, so that thebolt E passes directly through the several bosses.

It will also be seen that each pair of bosses bear against and support each other, and are.

braced by the perpendicular webs .while being.

retained in position by the axial bolt, so that there is great strength in thejoint of the gear in its perpendicular direction, and this serves to prevent any lateral motion or give of the gear, whereby breakage or fracture of the gear under ordinary circumstances is prevented.

Furthermore, by my construction Iconcentrate or center the parts of the joint of the gear and avoid spreading of the same, and the bolt extends from end to end of the gear, whereby the gear possesses greatstrength and is enabled to endure the severe wear and strain to which rial, which serves to ease the wear of the bosses on each other and prevent rattling of the gear. When the parts-are worn the nut of the bolt is tightened, so that the gear may always be kept firmly together,and when said bolt is worn it'may be removed and a larger one substituted therefor.

By removing 'the'bolt the stationary part of the axle and connected parts of the gear may be reversed and reapplied, as in Fig. 2, thus adapting the gear for low-down springs and bodies. For this purpose the web F is made shorter than the web F.

The gear is provided with suitable lugs attached to the journal-webs out of center for the connection of the turning-bars of-the gear, whereby said bars have a greater range of motion and power. 4

Having thus described my invention, What I claim as new, and desire to secure by Letters .Patent, is-

1; The turning portion of the axle, consisting' of thejournal and bosses, and a perpendicuto the gear of the turning portion, whereby the gear is adapted both for high andlow-dowu springs and bodies of vehicles, as stated.

4. The turning portion consisting of the 20 journal, perpendicular web, and b0sses,in G011]:

bination with the two-part stationary portion consisting of the bosses, perpendicular web, and horizontal irons or flanges, the two webs projecting from therespective bosses on oppo- 2 5 site sides of the axial bolt 0, substantially as and for the purpose set forth.
