JOHN A. LAMON'I, 0F CHICAGO,ILLINIOIS, ASSIGNOR TO AMERICAN STEEL FOUNDRIES, F CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY- JOURNAL BOX.

Application led April 28, 1921. Serial No. 465,268.

To all whom t may concern:

Be it known that I, JOHN A. LxMoNT, a citizen of the United States, res1d1ng at Chicago, in the county of Cool and State .5 of Illinois, have invented certaln new and useful Improvements in Journal Boxes, of which the following is a specification.

This invention relates to a railway car truck journal box. 4 o One object of the invention is t0 provide a simple, journal box having its parts' arranged ina manner to accommodate associated equalizing mechanism 1n an 1mproved manner. 1 Another object is to provlde an improved journal box having parts whereby it may move guidably in a truck slde frame and still permit the passage of parts therethrough in connection with the equalization of loads.

These and other objects .are accomplished by means of the arrangement disclosed on theV accompanying sheet of drawlngs 1n which j I Figure 1 is a fragmentary vertical longitudinal sectional view of a truck side frame and associated parts including my improved journal box.

Figure 2 is a. fragmentary horizontal 3o longitudinal sectional view of the same side frame showing its cooperative action with my journal box; j

. Figure 3 is an end elevation of the journal box; and, j Figure 4 is a side elevation of said jour- -nal bx. I w

The various novel features of my invention will be a parent from the following description an drawings and will be partioularly pointed "out in the appended claims.

By referring to the figures of the draw- 'ings it will be noted that I have disclosed my invention in connection with a side frame 10 forming part of a'six-wheel truck, said side frame having an intermediate pocket 11 for a middle journal box.12, said intermediate pocket 11- being formed between side walls13 which preferably are provided with wear plates 14.-

This journal box includes Va main central body portion for the reception .of a journal 15 and also includes outwardly and upwardly extending wing portions each having a pair of spaced side walls 16, which ative movements.

attheir outer ends are joined by an end wall 17. Accordingly wide open ended vertically arranged passa eways or spaces are formed at each side o the journal box between the main body portion, end walls 17 60 and the side walls 16. These vertical end walls 17 and the outer edges of the side walls 16 cooperate' with the pocket walls 13V or more particularly in this present case, with the wear plates 14 whereby the journal 65 box is guided 1n its relative vertical movements with respect to the side frame.

The top wall 18 vof the journal box is provided with a concave bearing portion 19 for the reception. of a rocking portion 20 70 of anl equalizing beam 2l upon which springs 22 are mounted. Mounted over the springs is a spring cap or yoke 23 in thc form of an inverted U having depending arms 24i'which extend freely downwardly 75 through the vertical open-ended passageways or spaces 25 formed by the walls 16 and 17 of the journal box. Operativel),1 connected to the lower ends of thev arms 24 arel equalizing levers 26 from which loads 80 are transmitted through the arms 24 of cap 23, through the springs 22, equalizing beam 21 to the top of the journal box. The journal box is provided with the hollow wings for the purpose of freely accommodating the arms 24 of the spring cap 23 and permittin movements of the latter thereby providing sucient clearance for all parts and preventing any interference in the oper- A combination of the load equalizing arrangement described in this parapra h is claimed in a copending application, erial No. 465,941, filed-April 30, 1921. y

It is my intention to cover all modiications of the invention falling within the spirit and scope of the following claims.

I claim: g1. A railway car truck journal box comprising a journal receiving portion and hollow wide open-ended wings having portions cooperating to guide vertical movements of said journal box, the openings through the' hollow wings permitting the passage of load equalizing parts.'

2. A railway car truck journal box comrising a journal receiving portion and holow w1de open-ended wings extending outwardly therefrom for guiding said boxin its vertical movements and for permitting 110 box in its vertical movements and to permit the passage of load equalizing parts therebetween.

4. A railway car truck journal box comprising a journal receiving portion, spaced sidewalls extending outwardly therefrom and terminating in end walls connecting said side walls whereby the journal box will be guided in its vertical movements and pro- 1,43e,ea3 i vides wide open ended openings through which associated parts may extend.

5. A railway car truck integrally formed journal box comprising a box portion for receiving a journal and the Atop of which takes the spring pressure, .spaced side walls extending upwardly and outwardly from -said box portionand end walls connecting said side walls for cooperating to guide the journal box in its vertical movements, said spaced walls, end walls and box portion forming walls of openings through lwhich Vassociated parts may extend.

Signed at Chicago, Illinois, this 18th day of April, 1921.

JOHN A. LAMONT.
