Specification of Letters Patent.

Application filed October 2, 1905. Serial No. 280.942.

T0 all whom it nfl/Cty concern:

Be it known that I, SPENCER Oris, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in End Sills for Cars, of which the following is a specification.

My invention relates to that class of end sills having a channel-beam member and gusset-plates secured to such channel-beam member extending below the lower edge thereof.

The principal object of my invention is to provide a simple, economical, and efficient end sill for cars.

A further object is to provide an end sill with suitable means for bracing and strengthening the principal member thereof, supporting the draw-bar shank, and connecting the principal member of the end sill with the longitudinal center sills.

Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a plan view of the angle-iron member of the end sills, showing the manner of connecting it with the longitudinal center sills; Fig.

2, a plan view of the complete end sill; Fig.

3, a side elevation of the same looking at it from the end of the car, and Fig. 4: a transverse central sectional elevation taken on line 4 of Fig. 2 looking in the direction'of the arrow. y

In the art to which this invention relates it is very desirable to provide at each end of the car an end sill with a main body portion or member formed of a channel-beam having top and bottom flanges, both of which are continuous and unbro en at the central portion of the sill, enabling both flanges to extend the entire length of the sill, if desired, and to provide means for supporting the draw-bar shank beneath such channel-beam member. It is also very desirable to provide means for bracing such channel-beam member and connecting it with the longitudinal sills of the car in such a manner that the shocks and strains will be effectually resisted. In order to accomplish these purposes an end sill is provided for each end of the car, having a main body portion formed of a channel-beam a, which extends from side to side of the car, each of such channelbeam members having an upper flange b and a lower flange c extending outward endwise of the car from its upper and lower edges, respectively, both of such flanges being straight, continuous, and unbroken at the central portion of the sill and from end to end thereof. Vertical angular gusset-plates d are secured to the web portions of such channel-beams by means of rivets e and are providedwith rearwardly-extending upright portions f, which are secured to the longitudinal center sills g by means of rivets 7i. The rearwardly-extending portions of these gusset-plates are substantially at right angles to the portions which extend longitudinally of the sill, and the longitudinal portions extend below the lower edge of the channel-beam member a suflicient distance toprovide beneath the continuous and unbroken bottom flange of the channel-beam member and between such gusset-plates a space i for receiving the draw-bar shank. A.

draw-bar-shank-supporting member j extends across the lower side of this space and is secured to longitudinal portions of the vertical gusset-plates, being formed of an angleiron having its horizontal flange c extending from the upper edge thereof endwise of the car and parallel with the lower flange of the channel-beam member. The rearwardly-extending vertical portions of the gusset-plates above described also extend below the lower edge of the channel-beam member and are each provided with an upwardly-projecting portion Z, which extends above the longitudinal center sills.

A top plate m is secured to the upper `flange of the channel-beam member by means of rivets n and to the rearwardly-extending portions of the vertical gusset-plates above described by means of connectingangles o, riveted to such top plate and gussetplates. This top plate extends rearward from the channel-beam over the rearwardlyextending portions of the vertical gussetplates and is provided at its rear edge with a strengthening angle-iron member p, which is riveted thereto and has an upwardly-extending fiange portion adapted to strengthen the top platevertically.

ICO

A horizontal gusset-plate 'q issecured to the top flanges r of the longitudinal sills by means of rivets s, and an angle-iron brace t is mounted upon such horizontal gusset-plate, to which it is secured by means of rivets u, which also connect such brace and gusset.- plate to the upper flange ortions of the longitudinal sills. This ang e-iron brace has an upwardly-extending flange portion Q) and extends over the horizontal gusset-plate and the longitudinal sills. At its opposite ends w the brace extends horizontally beneath the top plate and longitudinally ofthe end sill at an oblique angle, being secured to the channel-beam member and beneath the top plate by means of suitable rivets. Longitudinal side or intermediate sills y may be mounted upon opposite sides of the center sills and connected with the horizontal gusset-plate and angle-iron brace above described.

By this arrangement it will be seen that the channel-beam member has straight and continuous top and bottom flanges,r both of which extend without interruption' or curvature throughout its entire length, thus enabling the ordinary channel-beam of commerce to be employed to form the principal member of the end sill. The upright gussetplates, extending, as they do, below the lower edge of the channel-beam and forming a space beneath its bottom liange for receiving the draw-bar shank, obviate the necessity of making a notch in the lower side of the channel-beam member, which would have the effect of weakening it. The beam is also strengthened horizontally by the horizontal gusset-plate and vertically by the vertical gusset-plates. It is also further strengthened by the manner of connecting the angle-iron brace member with the horizontal gussetplate and with the longitudinal sills and channel-iron member.
