WILSON SYMONS, OF CHICAGO, ILLINOIS.

CAR TRUCTURE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed March 30,1907. Serial No. 365,484.

To all whom it may concern:

Be it known that I, WILsoN E. SYMoNs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Gar Structure, of which the following is a specification. I

This invention relates to car structures, and more particularly to the underframing for car bodies.

One of the principal objects of the present invention is to provide an end sill composed wholly or partially of metal, said sill being strong, and practically indestructible, in order that it will withstand the rough usage and hard strains incident to this type of structure, and furthermore having effective means, whereby the longitudinal sills and the car siding can be secured in place.

In the accompanying drawings:Figure 1 is a plan view of one embodiment of the invention. Fig. 2 is an end view of the same. Fig. 3 is a cross sectional view. Fig. 4 is a side elevation of one of the joints between the sill sections. Fig. 5 is a detail perspective view of one of the clamping plates. Fig. 6 is a crosssectional view through the structure shown in Fig. 4. Fig. 7 is a detail horizontal sectional view through one of the plates, showing the particular construction of the spurs. Fig. 8 is a detail perspective view of a slightly modified form of construction. Fig. 9 is a detail view of another modification.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, the end Bill of the car comprises a metallic shell preferably, though not necessarily composed of cast steel and having an upper wall 10, a lower wall 11, and a rear wall 12 that connects said upper and lower walls. The rear wall is provided with sets of spaced rearwardly extending ears 13, and between these ears, mortises l l are formed in said rear wall. The front side of the shell is open, but the upper and

lower walls

10 and 11 are preferably provided with oppositely disposed inwardly extending flanges 15 that terminate short of each other. Other inwardly extending flanges 16 are carried by intermediate portions of the upper and

lower walls

10 and 11, and constitute stops, as hereinafter explained.

The end sill can be employed under certain. conditions, as thus constructed, but there is preferably located therein, a wooden core 17, which fits snugly between the upper and

lower walls

10 and 11 and the

flanges

15 and 16. This core has on its outer side a longitudinal rib 18 that extends between the flanges l5, and projects from the open side of the shell. In practice, the core may preferably be composed of two or more sections driven through opposite ends of the shell. As shown in Fig. 3, the rib 18 constitutes convenient means to which the siding 19 can be nailed, as shown at 20. Moreover, it will be evident that this rib projecting beyond the outer face of the shell, serves to space the siding therefrom. v

The longitudinal sills, designated 21, have their ends fitted between the cars 13 of the different sets, to which cars, they are secured by transverse bolts 22. The said ends of the longitudinal sills are furthermore provided with tenons 23, which tenons engage in the mortises l4, and project into the shell, as illustrated in Fig. 3. It will be observed, however, that said tenons terminate short of the vertical plane of the flanges 16, and inasmuch as the rear side of the core 17 is abutted against the outer sides of said flanges, the tenons are spaced from the core. The longitudinal sills 21 are each preferably constructed of two or more sections, these sections being arranged end to end, and having a broken joint 24 between them. In order to effectively secure the sections together without weakening the sills by a plurality of comparatively large vertical bolt openings therethrough, the following mechanism is preferably employed. Clamping plates 25 are located on opposite sides of the sections and bridge the joints between them. These plates are provided on their sides with inwardly projecting spurs 26, which spurs are pointed, and have certain of their sides, as 27 perpendicular to the inner face of the plate, while the opposite sides are arranged at an inclination, as shown at 28. The spurs that engage in one 'of the sections have their corresponding faces disposed in perpendicular relation, as described, while those that engage in the other sill section have their opposite faces perpendicular. This it will be thought will be clear by reference to Fig. 7. The spurs are embedded in the sections, and the plates are held in position by transverse horizontal bolts 29 that pass through said plates and through the sections. Preferably a single and comparatively small vertical bolt 30 extends through the overlapping ends of the sections.

In one embodiment of the invention, the clamping plates are provided along their lower edges with longitudinal flanges 31, which extend beneath the sills. These flanges are preferably provided with depending eyes 32, to which the brake rigging or portions thereof may be secured if desired. The flanges 31 are not on tirely essential, and may be dispensed with, as illustrated in Fig. 8, wherein a plate 33 is disclosed having the usual spurs 34. Plates of the character shown in Fig. 8 are particularly useful where the joints between the sill sections are located over the transoms or needle beams of the truck. These plates are preferably of cast steel, though they may be of iron or wrought longitudinal sills are shown substantially side by side,

because of the cutting away of the said sills, it will be evident to those skilled in the art, that in practice these joints or splices are disposed in staggered relation in order to preserve the strength of the under frame as a whole.

An under-frame for car bodies is thus constructed, that is very strong and durable, the metal is practically indestructible, and while wood may and is preferably employed as a core, this wood need not be of the high and expensive grade that is necessary for the ordinary end sill. Moreover, it will be evident that the ordinary siding and longitudinal sills may be effectively secured to the end sills. While the longitudinal sills are shown of wood, and can be made of comparatively short sections, still it will be observed to those skilled in the art, that metallic longitudinal sills may be employed in connection with the end sill set forth. I

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I. claim as new, and desire to secure by Letters Patent, is:
