RAILWAY TRUCK.

Application filed July 13,

T0 all whom t may concern Be it 1itnown that l, lViLLuM ll- Yoon- Ano. a citizen of the United @tot residing at Forest Hills. in the county el Queens and State of New York, have invented certain ne and use'tul Improvements 'in Railway Trucks. of which the itollowiiio i5 specification.

This invention relates to railwaiv trucks, particularly to trucks o't` the swing or lat-- eral motion type, and while it is more es pecially useful in connection with locomotive engine trucks, it may be adapted to service in trucks tor tenders and other railway vehicles. t is particularly adaptable for use in connection with narrow gauge locomotives and locomotives m which Jche swing oic the bolster is very large.

1li/lore specifically considered, my invention has to do with trucks of the inverted rocker type, and one its primary objects is the provision et an improved connection between the bolster and the rocker which is simple and effective and does not have certain objections inherent in previous trucks ot this general clniracter, and which insures proper register between the bolster and the rocker at all times. Another object of the invention resides in the provision ot a connection ot the character specified by means of which the rocker will' properly follow the bolster in the event ot the lifting of the bolster in and out ol" the truck.

These and such other objects as may hereinatter appear, or are incident to my invene tion, l obtain by means oil a construction which I have illustrated in preferred 'i'orm in the accompanyinp,- drawings, wherein:

Fig. l is an end elevation and partial transverse section through a twoswheel truck to which my improvements have been applied; Fig'. 2 is a plan view ot the truck shown in Fig. l; 3 is a section taken on the line 3--3 of Fig. l; Figs. Ll, 5 and G are respectively a side elevation, an end elevation and plan view ot the rocker employed in carrying out my invention; Fig. 7 is a perspective view of a member forming part of the connection between the truck, bolster and rocker; and Fig. 8 is a bottom plan view of the device shown in Fig. 7.

Specification of Letters Patent.

Patented May 30, 1922.

1920. serial No. 395,907.

Aiailroad service and it includes a main trame l, preferably of cast steel` which carries the wheels 2, axle and bearing boxes l in the customary manner. The truck bolster is indicated at B and it is provided with the customary center pin 5, slotted at 6 to receive an end ot the equalizing bar 7, and it is provided on :its lower face with the Vshaped bearing` members Sl which are adapted to rest upon the rocker indicated at C. The rocker C comprises the cams 8, each ot which. at the bottom, at opposite edges, is provided with a journal 8a; the intermediate portion 9, which serves to connect the two cams and preferably formed integrally therewith; and the upstanding lugs l0, preterably 'formed integrally with the portion 9. These lugs l0 are spaced and at their upper ends are provided with a pin or connesting member l1, the purpose of which will appear.

Dependingv from the bolster B is a member l2 provided with a head 13, such member being` forked at the bottom so as to fit over the pin ll in the manner shown in Fig. l and l. he 'forked ends of the member l2 are apertured tor the reception ot the bolt or pin lll, the parts being' so disposed that there is considerable lost motion between pins ll and lil. llVhere the depending member l2 is not made integral with the bolster, but is a separate member, as shown, the head 13, thereof is slotted, as at l5,so as to receive the end olil the equalizingbar 7 which thus serves to hold the member in place.

The connection thus formed between the bolster and the rocker is a simple and eftective one, takes up a minimum space, and always insures proper register of the bolster and rocker, the advantages of which will be readily understood by those skilled in the art. Furthermore, there is sufficient lost motion for all normal conditions and in the event of the lifting of the bolster in and out of the truck the rocker properly follows the bolster, a feature which has many practical advantages. It will be clear that the improvements are particularly useful in narrow gauge trucks and where the swing of` the bolster is very large, and they are applicable to trucks havingr more than one rocker.

What I claim is: l. A lateral motion truck comprising in combination with the truck frame, a bolster, an inverted rocker between the frame and the bolster', and means providing a lost motion connection between the bolster and the.

rocker.

2. In a railway truck, the combination of a bolster, an inverted rocker, andi means for securing register of the bolster and rocker depending from the bolster and adapted to engage the rocker.

3. In a railway truck, the combination of a bolster, an inverted rocker, a rojection on the rocker, and means depending from the bolster and adapted to engage said projection for securing registry of the bolster.

4. In a railway truck, the combination of a bolster, an inverted rocker on which the bolster rests, and a substantially verticallyr extending member connecting the bolster and rocker. y

5. In a railway truck, the combination of a frame, a bolster, an inverted rocker intermediate the frame and bolster on which the bolster rests, and a substantially ver v tically extending member forming a lost motion connection between the bolster and the rocker.

6. In a railway truck, the combination of a frame, an apertured bolster, an inverted rocker intermediate the frame and bolster on which the bolster rests and a headed connecting member on the bolster the shankof an inverted rocker between the frame and the bolster, and meansV for securing register of the bolster and the rocker comprising means depending from the bolster andl means on the rocker engaged thereby.

9. A' laterall motion truck comprising in combination with the truck frame, a bolster,

aninverted rocker resting on the frame and adapted kto supportthe bolster, and a lost motion connection between the bolster and the rocker which is adapted to carry the rocker with the bolster upon occasions when the latter is lifted from the truck.

In testimony whereof, I have hereunto signed my name.

WILLIAM E. WooDARD.
