UNITED STATES PATENT OFFICE.

VINTON E. SISSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO WALTER P. MURPHY, OF NEW YORK, N. Y.

RAILWAY-CAR.

Application filed April 24.

To all whom it may concern:

Be it known that I, VINTON E. Srsson, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and use-' ful Improvements in Railway Cars, of which the following is a specification.

My invention relates to the construction of railway cars, and more particularly to the trucks or running gear of the car, and the means for supporting the car body on said trucks or running gear.

According to standard practice the body of arailway car is provided with transverse body bolsters, one for each of the trucks, and the bolster is pivoted, in each case, usually by a center plate and king pin arrangement, to the bolster of the truck which distributes the load to the journal boxes and axles. This method of construction involves the use of two bolsters for each truck, both of which must be very'heavy at the center since the entire load on the truck is carried by the portions of the body and truck bolsters which bear one upon the other. 'As a result the entire construction of the running gear must be relatively heavy.

My invention provides a railway car truck which is constructed upon an entirely different principle. The car body is supported at each side directly upon the journal boxes of the axle so that there is no concentration of the weight of the car on any one point on the body bolster. Moreover, it is possible to do away entirely with the usual truck bolster. The supporting devices at each side of the car consist of coengaging members associated with the journal box and with the end of the body bolster so articulated that relative angular movements are possible between the axle and the car body to give the running gear sufiicient flexibility for rounding curves.

By reducing the weight of the body bolster and of the running gear it is possible for a freight car of ordinary size to employ twowheel'trucks instead of the usual four-wheel trucks, thus economizing in material and further reducing the weight of the car.

The principal object of the invention is to provide a railway car truck of this character and more particularly to provide a two- Specification of Letters Patent.

wheel truck, although the invention might readily be adapted to four or six wheel trucks.

The invention consists in the novel improvements, constructions, arrangements and devices to be hereinafter described and cla med for carrying out the above stated ob ect and such other incidental objects Wlll appear from the following description of certain vention.

In the drawings,

Figure 1 is a side elevation of a two-wheel truck constructed in accordance with my invention. I

Fig. 2 is a fragmentary plan view of one end of the truck.

Fig. 3 is a sectional view on lone 3-3 of Fig. 1.

Fig. 4 is a sectional plan on line 44 of Fig. 1. I

Fig. 5 is a vertical sectional view on line 55 of Fig. 2.

Fig. 6 is a sectional view corresponding to Flg. 5 but illustrating a development or modification of the construction shown in the first five figures, and

Fig. 7 is a fragmentary sectional view illustrating another modification.

Like characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 5 inclusive, 1() designates one of the wheels of the. car, 11 the axle, 12 the axle journal and 13 one of the journal boxes. In the drawings one end only of the truck is shown. It will be understood that the constructions at the other side of the car will be the same. 14 represents the flooring of the car, 15 the longitudinal sills and 16 a body bolster which extends across the car from side to side.

The journal box 13 is provided preferably on opposite sides with spring supports 17 which are shown as cast integrally with the journal box, although this is not essential. On the spring supports are arranged coiled

springs

18, 19 on which is sustained a sliding member 20 having depending channelshaped webs 21 which lie in vertical recesses 22 formed in the sides of the journal box. The sliding member 20 is provided with a pair of spaced, upstanding webs 23 formed preferred embodiments of the in- Q isomers at the top with bearings 24 for the outturnecl gudgeons 25 of a L l-shaped hanger 2c. The hanger swings on an axis transverse respect to the car. Connected to a and. depending from the body bolster i6 is a hanger bracket 2/? having webs 23 at right angles to the webs 23 on the sliding mem ber the webs 28 being formed with bearingg recesses eulapteri to receive the ends is oi. a hanger 39 the middle portion of which is formed with an upward bencl to provide a seat for engagement with hanger 26.. The lower ends of webs 28 stand close to webs 31 forming part of the vertically sliding mem- 315 her 20, the webs 31 bein curved so that, as

the hanger 26 swings orwardly or backwardly, a uniform distance will be maintained between the lower ends of webs 28 and webs 31, or it one pair of

webs

28, 31 20 are in. contact the hanger 26 may swing without increasing the pressure between the hanger bracket on the car boo; and the vertically slidable member 20. l referably the truck structure at one side of the car is connccted with the corresponding structure at the other sirle of the car. In the construction shown in the drawings a pair of angle bars 32 are secured: to the lateral rojections 33 on the sliding member 20. hese angle to bars are connected similarly to the sliding member associated with the journal box on the other siiie oi the car.

' in Fig. 6 l have shown a development of or improvement upon the truck illustrated as in i to 5 inclusive. lln the construction shown in l to 5, the hanger hraclret on the car body will be likely, in operation, bear on one side or the other upon one of the webs 31 of the slioiing memas her 20 that is, the sliding member anti its journal box will naturally tilt on the journal of the axle one way or the other in ac coraiance with the draft on the car, and this will produce a certain amount of friction 4E tending to hamper the treeolom of movement of the hangers. overcome this ll provide shown in s, a pair of balancing figs which are interposeol between the i G body of the car. designated 3 iin Fig. 6 tension anrl compression springs. ike of the spring in each case is secured to a disk 35 having a contering sturl 3% the clislr being piv ted. to a as bracket 37 sccurecl he sizie of the body bolster 16. The other oi? spring 341 is secured within a housing 38 which is pivoted to a bracket 39 secured to one of the lateral projections 33 on the sliclin memso her 20, the transverse angle bar designated 32 in this figure being inverted for convenience in attaching bracket 39.

A. somewhat riifferent arrangement is shown in Fig. Z. The hanger braclret assoelated with the car hotly, here clesignaterl 2?, is provided with a pair of antitriction rollersiO aclaptecl to bear upon the webs 31 of the sliding; member 20.

in Figs. ti and 7 the parts not specifically mentioned are the same as corresponding parts in Figs. 1 to 5 anol are given the same reference numerals.

@peration: The car body has a floating relation with the runnin gear giving the bo iy of the car capacity i or movement with respect to the running gear both in the directior: of the length of the car and also laterally ithin certain narrow limits this relative movement between the body and the running gear 01 the car is universal with respect to directions in a horizontal plane. As a result the axle may assume an angular position with respect to the car body when the train rounris a curve. The movements of the car body with respect to the wheels are not, however strictly in a horizontal plane. As any forward. or lateral movement of the car body takes place through the pivotal movements of the hangers such longitudinal or lateral movements of the car body involve a lifting of the body from the running gear which isresisted by the weight of the car and. these movements are therefore seli' checkin Any suriden pull on the draft gear of the car which it will be understood is connected with the hotly, will result in a slight forwarci movement of the body with respect to the running gear, anti a raisingot the car body this to the pivotal su pension thereof, This action helps to relieve the draft gear springs of abnormal stresses in pulling and also in bull-ling.
