To all whom 'it may concern:

Be it known that I, GEORGE Gr. FLOYD, a citizen of thev United States, residing at Granite City, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Car-Truck J ournal-Boxes and Oil-Cellars, of which the following is a specification.

My present invention relates to car-truck journal boxes and oil cellars, and one of its objects is to so shape and construct the sideframe as to form the upper portion of a journal box, the lower portion of the box being made separate and independent from the upper portionand adapted to coperate with the portion formed on the side-frame so as to constitute the complete journal box.

I am aware that others havel suggested many forms of connection between the journal box and side-frame, these including sideframes having. journal boxes formed integral therewith, side-frames having portions of the box formed integral therewith,

together with many modications of the constructions just described.

It is well understood that in practice the wheels of a car truck must be removed at comparatively frequent intervals for returningor substitution, and for that reason the object sought in each instance has been to so construct a truck that the removal may be quickly and easily accomplished, and, at the saine time, provide a construction which may not become loose through loss of bolts or nuts. This'is attained in an integral construction, with the drawback that the l i breakage of any part of the journal box necessitates the discarding of the entire sidefrauie, while in the divided journal box construction it becomes necessary to employ bolts for holding the associated parts tohigether.' Therefore, when the nuts become loose, even though they are not lost, the connection between the associated parts will admit sand and dust, which, entering the journal, causes a. hot box with consequentdelay and loss.

- One of the objects of my invention is, therefore, to provide a side-frame and journal box construction wherein the substantial parts of the box, such as the lugs and top wall, are formed as a part of the sideframe while the oil cellar is separate and is held in operative position solely by the -i weight transmitted by the side-frame to the wheels, and without the use of bolts.

A further object is to so construct .the parts that there shall be a tight joint maintained at all times. In my novel construction the parts may be disassociated by merely elevating the side-frame to a height equal to the height of the lugs. The wheels may then be rolled out asdesred and the journal box and parts reinoved.-

This invention will be best understood by reference to the following description when taken in connection with the accompanying drawings illustrating one preferred embodiment thereof. f

On the drawings-Figure 1 is a longitudinal vertical sectional view through the -center of the box and substantially on the line 14-1 of Fig. 2. Fig. 2 is a transverse sectional view t rough the box and showing a segment of the side-frame, taken substantially on the line 2-2 of Fig. 1; and Fig. 3 is a detail plan view of the pressed metal box element, the portion of the box integral vith the side-frame being shown in dotted ines.

Referring to the drawings it will be noted that the cast metal side-frame 5 has a lower tension bar or member 8 and a .top compression member 6 provided near its ends with a centrally disposed rib 7 extending longitudinally of the frame. The` frame has also at each end a llat horizontal yplate portion 9 adapted to form the to of the journal box and downwardly extendi and 11 which, when the parts are assembled, project nearly to the lowerside of the axle l2 as shown in Fig. 1. At their outer ends the side walls are connected, near their free edges, by a web or wall 13 which,\together with the ends of the side wall and the top of the box, form a seat for the journal box cover which may be pivotally moun'ted'in ng side wallsV 10 the usual manner upon a lug 14 rojecting ox. The

upwardly from the top of the refcrably rear end of the box portion is constructed to provide a slot 15 o'r the reception of the usual dust guard. A' pair of in Fig. 2. t The lugs of each pair are preferthe outer end thereof in position to engage ment, and

the outer end of the wedge 21 which is positioned above the brass 22 in the usual manner, said lug serving to prevent' the wedge from slipping out of the box and also servingto prevent the box from sliding too far onto the axle.

The lower fportion ofthe journal box, which is made independently from the upper portion, I have termed the box elethis element is designated generally by the reference character 23. This l Vfor the side-frame.

box element is preferably pressed from an integral sheet of metal so as to form a bottom 24 having a depression 25, a' shallow' front end wall 26 and side walls 27 and 28.

'The front and rear corners of thefside walls are removed, as will be evident from Figs. 1 and 2, leaving relatiyely narrow portions nearv the'penter of the box which are bent inwardly toward each other at 29 and 30 to form a partial top adapted to restl upon the wedge 21 and prevent the box element from dropping away from'the axle. The inner face of the top portion of the box is preferably recessed at 31 to permit the

top

29, 30 of the bgx element to rest therein so that the top 9 may 'be supported throughout its length upon the wedge 21 thereby insuringl a broad,l stable supporting surface The upper portion of the side walls 27 and 28 and the adjacent portion ofthe

top members

29 and 30 are preferably cut away to form recesses 32 adapted to receive the pairs of holding lugs or lingers 16 and 17 of the upper box portion. These lugs which arealso adapted to engage in recesses in the sides of the wedge and brass 21 and 22 serve tol prevent longitudinal Adisplacement of the i l box element, the brass and the Wedge Thesides of the box element beneath the lugfreceiving recesses are bent outwardly to form the ribs 33 and 34 adapted to lit in thev grooves 18 and 19 in the upper box portion to assist in maintaining the element In f proper longitudinal relation to the sideframe. A groove 35 isprovided on the under side of the web or wall 13 into which the free .edge .of thefront wall 26 of the box A. element ,ufivts,`forming` a seal when the box.

portions are assembled in operative relation. The rear'end of the box element is provided with an upturned flange 36 which, I,

together with the bottom, side walls and front wall, constitutes the oil cellar beneath the axle. A separate piece of metal 37 hav- I inga flange similar to the flange 3G is secured by rivets 38 or other preferred fastening means to the rear end of the box element so that the

flanges

36 and 37 are spaced apart to form a pocket adapted for the reception of the usual dust guard which is inserted at the top of the box into the guideway or groove 15. l

'In assembling the parts of my improved journal box and oil cellar, the box elementis first slipped over the end of the axle and the brasses and wedge are placed in position upon the top of the axle so as to support the box element. Thefside-frame is then lowered over the box element into the position shown in Fig. 1. When `the box portions are assembled as shown, the box element is prevented from movement relatively to the side-frame, by the engagement of the front wall 26 in the groove 35, by the groove and rib-connection between the sides of the box element and the side walls of the upper box portion and finally by the-lugs 16 `and 17 located in the recesses in the top of the box element. It will be apparent that the two portions of the lbox are held rigidly together when in operative relation without the employment of bolts, clasps or other fastening means and that the construction is light, strong and durable. Whenever it may become necessary to remove the box j or an axle for repairs or for any other reason, the` parts may be readily disassembled by simply lifting the side-frame carrying the upper portion of the box olf from the lower portion. and brasses may then .be readily slipped off over the end of the axle.

j Although I have not shown a dust guard in the recess 15 provided therefor, it will be j The box elementand the wedge j understood that a divided guard is eontemplatednthat is, stantially the transverse axis of the axle.

While I have shown and described a preferred embodiment of this invention it willbe obvious' that various changes in the construction and arrangement of the various parts may be resorted'to without departing from the spirit of the invention or sacrificing any of the material advantages thereof.
