OIL-BOX RECEPTACLE FOR CAR-TRUCKS.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed October 4,1906. Serial No. 337,417.

, following is a specification.

This invention relates to railway trucks, and more particularly to a novel oil box receptacle designed to receive and retain oil boxes of standard construction now extensively in use and manufactured by various concerns.

The object of the invention is to provide what is known as acast steel car truck with oil box receptacles so constructed that in equipping cars with these trucks, the oil boxes most extensively used at this time, such as the M. C. Bl, the Symington, the McOord, and others of generally approved form may be employed without alteration of the boxesor trucks.

The further object of the invention is to provide an oil box receptacle, one wall of which constitutes a solid abutment against which the oil box is urged and held by a movable wall or follower which is in turn urged and retained by a wedge-shaped key, so that notwithstanding the slight contraction of the box, the latter may at all times be held rigidly against the fixed abutment in order to insure the absolutely accurate alinement of the axles and the proper tramming of the wheels.

Still another object of the invention is to provide a truck with a poling pocket or bracket similar in function to the pockets ordinarily applied to the corners of car bodies, locomotive tender frames, and the bumping timbers on the fronts of locomotives, this pocket being so disposed that the metal of which it is formed will augment and stiffen the upper wall of the box receptacle.

The invention also resides in various novel features of construction and arrangement to be hereinafter fully described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In the said drawings-Figure 1 is a side elevation of one end of a truck side member showing the journal box and axle in section. Fig. 2 is a sectional elevation similar to Fig. l substantially on the line 22 of Fig. 3. Fig. 3 is a horizontal section on the line 3-3of Fig. 1 with the axle and interior parts of the journal box removed. Fig. 4 is a side elevation of the journal box, the movable wall or follower of the box receptacle and the key, the upper and lower members or walls of the receptacle being shown in sectionv Fig. 5 is an elevation of the movable wall or follower viewed from the inner side. Fig. 6 is a sectional view of a modified form of follower. Fig. 7 is a side elevation thereof, and Fig. 8 is a plan View of one end of the truck side member, showing the poling pocket and the safety chain lug or web in section.

Each part is indicated by the same reference character in all of the views.

1 indicates a portion of a truck side member of that type shown in my co-pending application 335,413, filed September 20, 1906. This side member is formed in a single piece of cast steel and comprises upper and lower bars 2 and 3, the bar 2 being straight and the bar 3 of drop center form; These bars are con nected by vertical struts, one only of which, to wit, the end strut l is here shown, it being understood that except as to certain particulars to be mentioned, the particular form of side member is immaterial so far as my present invention is concerned. The end strut 4 is located at some distance from the outer ends of the bars 2 and 3 in order to form an open-sided jaw or oil box receptacle 5, between the upper and lower horizontal members 6 and 7 in which the oil box 8 is received and held in abutting relation with the strut 4,

which will thus be seen to constitute the inner wall of the receptacle 5 and a solid abutment for the inner side of the oil box. As is well understood bythose skilled in the art, usual types of oil boxes, particularly those designed for use in connection with freight cars, have an exterior contour substantially as shown in the accompanying drawing. That is to say, these boxes are rectangular in cross section, and their side walls are each provided with upper and lower lugs or projections 8 and 9 disposed horizontally and connected by an open bolt-way 10 constituting a continuation of vertical openings 11 formed in the lugs 8 and 9 for the reception of the keys or bolts by means of which these boxes are ordinarily held in position. Heretofore, it has been impossible to employ these well-known boxes in connection with known types of cast steel trucks without either the alteration of the boxes or trucks. Such alterations are obviously undesirable, both by reason of the expense involved, and also because the removal of the projecting portions from the boxes renders them non-interchangeable with the boxes mounted in trucks of other types. My invention, therefore, contemplates the formation of the cast steel truck side members in a manner to accommodate the various makes of boxes now extensively in use without alteration of the latter, so that in replacing the present truck equipment of a railroad with my cast steel trucks, the boxes now in use can be readily utilized without rendering the latter incapable of use in connection with trucks of other types. To this end the inner wall, strut or abutment 4 at each end of each side member, is widened or extended beyond the opposite sides of the body of the side member as shown in Fig. 3 and is provided in its inner face with a vertical cavity 12 of proper form and dimensions to accommodate the keyway l0 projecting from the inner side of the oil box. The upper ends of this vertical cavity 12 open into horizontal enlargements or pockets 13 of sufficient dimensions to accommodate the lugs 8 and 9 which,as before explained, extend'laterally from the side of the box adjacent to the top and bottom edges thereof. This manner of forming the box abutment 4 not only accommodates the projecting portions of the ordinary oil box,. but serves also to provide an interlocking connection between the box and the side member, since the extension of the projecting portions of the boxes into the cavities of the side member serves to retain the box against possible longitudinal movement. It will be noted, furthermore, that the widening of the abutment or strut 4 affords an extended bearing for the side of the oil box which will effectually minimize the tendency of the box to assume an angular position in the receptacle. At the outside of the box 8 is located an outer receptacle wall or follower 14 extending vertically between the upper and lower members of the receptacle or jaw 5 and adjustable toward the inner wall or abutment 4 for the purpose of urging the oil box solidly against the latter abutment. This wall or follower is of substantially the same width as the strut 4, and its inner face is likewise provided with a vertical cavity 12 having horizontal terminal enlargements or pockets 13* for the reception of the projections at the outer side of the oil box. The outer side face of the follower 14 is provided with a vertical keyway 15 for the reception of a tapered key 16 preferably having its outer side face curved as shown in Fig. 3. Y The opposite ends of the key 16 pass through slots 17 and 18 in the outer ends of the members 6 and 7. The key 16, by its engagement with the follower 14 preventsdisplacement of the latter laterally of the side member, and also constitutes a wedge which, when urged in a downward direction, forces the follower 14 toward the abutment 4 and thus serves to clamp the oil box tightly between said abutment and the follower. It will thus be seen that by the manipulation of the wedge or key 16, any wear or contraction of the parts may be compensated for so that the box will be securely held against the abutment 4 at all times and in absolutely proper position to compel the axles to remain in parallelism, to compel a proper tmmming of the wheels. In Figs. 6 and 7 are shown a modified form of follower, which is only of sufficient width to obtain a bearing against the outer side of the box at points between the upper and lower lugs, and at opposite sides of the keyway 10, the follower being cut away as indicated at 14 to accommodate the lugs 8 and 9 which are not housed by the pockets or enlargements as in the construction previously described.

The upper bar 2 of the side member is provided with materially thickened portions 2 extending from points adjacent to the outer ends of the bar to points between the end struts 4, so that the upper members of the jaws or oil box receptacles and the upper bar at its junctures with the struts 4 will be materially strengthened. This formation is adopted for the reason that that portion of the truck structure thus strengthened is subjected to the greatest strains, due to the fact that the weight of the car body is sustained by the truck frame, and that the latter is in turn sustained by the journal boxes through the medium of the upper members of the box receptacles or jaws. Preferably, these thickened portions 2 of the side member have their upper surfaces curved, as clearly shown in the drawings, and are surmounted by integral poling brackets 17 di'sposed at an angle across the upper member 6 of the receptacle and formed with a poling pocket 18 opening toward the end of the side member.

Extending inwardly from each bracket 17 andpreferably along the middle of the bar 2, is an integral safety chain lug or web 19 which tapers. from the top of the bracket 17 and finally merges with the upper surface of the bar 2 beyond the strut 4, it being observed that this lug or web extends beyond opposite sides of the strut by reason of the fact that the poling bracket is located directly above the oil box receptacle, and preferably in substantially the vertical plane of the axle. Adjacent to the bracket 17 the lug'or web 19 is provided with an aperture 20 for the attachment of the check or safety chain. It will thus be seen that the poling bracket 17 and the lug or web 19 constitute in effect a combined poling and safety chain attaching bracket, and it will of course be understood that this structure is duplicated at each end of each side member of the truck.

Before concluding, attention is directed to the fact that while the structure shown and described has been especially designed as a feature of a particular cast steel side member for trucks, it is capable of use in connection with various types of cast steel side members,

and in fact with trucks of radically different types, whether of cast or built-up construction. It is, therefore, to be understood, that while the illustrated embodiment of the invention is preferable, 1 do not wish to limit myself to the exact construction of oil box receptacle herein shown nor to its use in connection with any particular kind of truck; on the contrary, I reserve the right to utilize the invention in any relation to which it may be adapted, and to modify the construction at will within the scope of the protection prayed.
