THOMPSON HERSEE, OF BUFFALO, NEW YORK.

RUNNING-GEAR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 263,516, dated August 29, 1882,

Application filed January 19, 1892. (No model.)

To all whom it may concern Be it known that I, THOMPSON HERSEE, of

the city of Buffalo, in the county of Erie and- State of New York, have invented new and useful Improvements in Running-Gears for Railwaybnrs, of which the following is a specitication.

This invention relates more particularly to improvements in the running-gear of railwaycars, and has for its object to reduce the resistance of the running-gear.

Myinvention consists of the particular construction of the running-gear, as will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is a side elevation of a railway-car provided with my improvements. Fig. 2 is a fragmentary vertical longitudinal section oi'one end of the car. Fig. 3 is a crosssection of the car. Fig. 4 is a sectional elevation of one of the axles and connecting parts. Fig. 5 is a top plan view of one ofthe axles and connecting parts. Fig.6 is a cross-section in line a; 00, Fig. 4.

Like letters of relerence refer to like parts in the several figures.

A represents the floor, B the sides, 0 the ends, and D the root, of a railway-car. The iloorA is composed of cross-beams a, constructed of rolled iron, preferably of I shape, and flooring a, which is bolted or otherwise secured to the upper side of the beams to, and which runs lengthwise of the car. The crossbeams to are connected by two longitudinal stringer-plates, I), secured to the under side of the beams to by angle-irons 1), running from end to end of the car.

0 represents lateral diagonal braces, arranged at suitable distances apart, and secured with their lower ends to the plates 1) and with their upper ends to the ends of the cross-beams a.

F represents the wheels of the car, andfthe axles to which the wheels F are secured. Each wheel is secured to a separate axle, which projects about the same distance on both sides of the wheel.

G represents an axle-box, of any well-known and suitable construction, applied to the outer portion of each axle f, and g is an elliptic or other suitable spring, secured to the upper side .under sides of the cross-beams a.

of the box Gand the under side of the floorA ot' the car.

H represents a journal-bearing resting on the innerportion ofthe axlef, and his a spring of the same or similar construction as the spring g, and secured to thejournal-bearing H and the under side of the car-floor. The springs g h are secured to the car-floor by means of longitudinal pieces 9, secured to the The two journal-bearings H, applied to the inner portions of two opposite axles, f, are connected by a tube or box, I, to which both bearings are firmly secured, and which surrounds and incloses the inner portions of both axles. Each axle is provided near its inner end with a reduced portion or neck,f, which is held in a bearing, H, secured in the box I by bolts h. The neck f is somewhat longer than the bearing H, whereby the axlefis allowed sufficient longitudinal play to permit the wheels to adapt themselves to slight imperfections ot' the track, while at the same time preventing the wheels from changing their gage to an improper extent.

Krepresents a spiral or other suitable spring, which is interposed between the adjacent inner ends of the two axles ff. This spring bears against a collar, k, secured to the inner end of the axle, and tends to press the wheels outward and hold their flanges snugly against the rails. This tendency ofthe flanges to hug the rails is increased by aninward inclination which is given to the axlesf, as clearly shown in Fig. 3, whereby the wheels, when in motion, will tend to run on the larger circle. The outward movement of the wheels and axles is limited by the neckf' at the inner end of the axle and a lug or shoulder, 9 which is formed on the axle-box G and bears against the outer end of the axle,

The stringer-plates b are provided with openings l for the accommodation of theboxes I, and two cross-stays, c, are arranged on opposite sides of each box I, as clearly shown in Fig. 2, whereby the weakening of the plate I) by the openings l is compensated for. The boxes I are provided with hinged covers or lids l and closed ends fitting snugly around the axles f, whereby the entire interior of the box I is made available as an oil-reservoir. Each box I is connected with the axle-boxes G on the same axles by curved pipes m, as clearly shown in Fig. 3, whereby communication is established between these parts. A portion of the oil which is introduced into either of the boxes G passes into the box I and lubricates the journals arranged therein. The box I forms a large oil-reservoir, in which a considerable quantity of oil can be stored, and from which itis gradually fed to the severaljournals arranged therein or connected therewith by the pipes at.

The wheels F will, by reason ofthe peculiar arrangement of the axles, always maintain the propertit oftheirflangesagainsttheinner sides of the rails, and as each wheel can turn independent ofthe others the car will pass around curves more easily and with less wear to the running-gear and rails than a car in which a pair of wheels is secured to the same axle.

I claim as my invention- 1. The combination, with the inwardly-inclined axles ff and wheels FF secured thereto, of the axle-boxes G and H, secured to the car-body and resting respectively on thcouter and inner portions of the axles, and thrust bearings H, applied to the inner ends of the inclined axles to resist the inward movement of the same, substantially as set forth.

2. The combination, with the axlesff and wheels F F, mounted thereon, of a spring, 1:, applied to the inner ends of the axles, whereby the latter are pressed outward and the flanges of the wheels are held against the rails, substantially as set forth.

3. The combination, with the axlesff and wheels F F, of necks f, formed on the inner portions of the axles, a box, I, provided with wheels F F, of necksf, formed on the inner portions of the axles, a box, I, provided with bearings H, a spring, it, applied to the inner ends of the axles, and bearings Gr, provided with a lug or shoulder, g applied to the outer ends of the axles, substantially as set forth.

5. The combination, with the axlesff and wheels F F, of axle-boxes G, a box, I, provided with bearings H II and springs g 71, whereby the bearings G II are connected with the car-body, substantially as set forth.

6. The combination, with the axlesff and wheels F F, of axle-boxes Gr, applied to the outer portion of the axles, bearings H, applied to the inner portions of the axles, and a pipe, whereby the oil-reservoirs of the outer and inner bearings are connected, substantially as set forth.

7. The combination, with the axlesff and wheels F F, of the axle-boxes G, bearings II, box I, connecting the bearings H and pipes m, whereby the oil-reservoir ot' the boxes G and I are connected, substantially as set forth.

8. The combination, with the car-body, of

the axlesff, wheels F F, stringer-plates b, secured to the under side of the car-body and provided with openings 1, through which the axles pass, and stay-plates a, connecting the stringer-plates on both sides of the openings 1, substantially as set forth.

THOMPSON HERSEE.
