CAR END' FRAME.

To all whom it may concern.

Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Car End Frames, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical section taken transversely through the platform portion of a car underframe, and showing a car end frame of my improved construction in elevation. Fig. 2 is a plan view of the end frame. Fig. 3 is a side elevational view of the end frame. Fig. 4c is a vertical section taken on the line H of Fig. 1. Fig. 5 is a horizontal section taken on the line .55 of Fig. 1.

lhis invention relates generally to railway car construction and more particularly to cast metal end frames for cars of the type disclosed in Patent No. 917,716, issued April the 6th, 1909, and No. 929,705, issued August 3d, 1909.

One of the most important features in the construction of the present forms'of railway cars, and particularly those cars utilized for transporting passengers, is the reinforcing of the ends of the cars so as to provide an exceptionally strong, rigid construction which will effectually resist crushing stresses delivered to the ends of the cars, consequently overcoming the tendency of the cars to telescope in case of collisions, and affording the greatest possible degree of safety to the occupants of the car.

My improvement contemplates a comparatively light weight, strong and-durable one piece cast metal structure which is formed and braced so as to efiectually resist end shocks and crushing stresses imparted to the ends of the car, thereby providing a construction which is anti-telescopic in effect.

The principal objects of my invention are to generally improve the construction of cast metal end frames disclosed in the pat ents above referred to,'to arrange and dis pose the various uprights or posts or cross pieces and braces forming the end frame so as to utilize to the greatest possible ad- Spc-ification of Letters Patent.

Application filedApril 9, 1912. Serial No. 689,569. I

Patented Dec. 31, 1912.

To the above purposes my invention con-' sists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

Referring by numerals to the accompany- .ing drawings, 1 designates the car under frame, 2 the end sill thereof and 3 the platform casting which parts are preferably formed integral.

. lvly improved end frame, as shown, includes a pair of upright members 4: which perform the function of door posts, a pair of outer members 5 which perform the function of corner posts and a pair of inter-' mediate members 6. All of these posts are preferably channel shape in cross section, although other cross sectional shapes may be utilized, if desired, and formed integral with and connecting the lower portions 'of the uprights 5 and 6 are vertically disposed web plates 7. Corresponding web plates 8 are formed integral with the lower portions of the uprights 4 and 6 and when the end frame is applied to the under frame, the web plates 7 and 8 bear directly against the outer face of the end sill of the under frame and said end frame is fixed to the under frame by means of rivets 9 or like fastening devices which pass through the web plates and through the front wall of the end sill of the under frame. Formed integral with the upper portions of the web plates 7 and pro 1ecting rearwardly therefrom is a horizontally disposed plate 10 and the central; portion of this plate between the uprights t performs the function of a threshold plate for the door frame. the lower portions of the posts or uprights 5 are rearwardly extending brackets 11 which rest directly upon the corresponding portions of the under frame and the horizontally disposed base flanges 11 of these brackets are fixed tothe under frame by means of rivets 12 or like fastening devices. The rear ends of the brackets 11 bear direetly against shoulders 13 formed on the under frame, and this arrangement, together with the bearing of the lower ends Formed integral with of the uprights against the front ends of the under frame, takes all shearing strain off the rivets 12. Any crushing stresses or shocks imparted to the upper portion of the end frame andwhich may tend to swing the upper portion of the frame inwardly will be resisted by the bearing of the brackets 11 directly on top of the under frame. The upper portions of the

posts

4, 5 and 6 are united by horizontally disposed rails 14:, preferably i..-shape in cross section. Formed integral with and projecting upwardly from the inner ends of these rails 14 in alinement with the door posts t are short upright posts or brackets 15. Uniting the upper ends of all the

posts

15 and 16 is a horizon tally disposed rail 17, preferably of inverted EL-shape in cross section, the horizontal flange 17 of which performs the function of a lintel for the door frame, said flange being widest at its central portion and gradually tapering toward its ends. Formed integral with and projecting upwardly from the ends of the rail 17 are uprights 18 adapted to receive the lower portions of the ventilator frames and formed integral with and extending outwardly and ddwnwardly from these uprights 18 are inclined brackets 19 adapted to support the side portions of the roof structure of the car body and the lower ends of said brackets are connected to the end portions of the rails 14. The upper ends of the posts 5 are notched or cut away as designated byQO so as to receive the side plates of the car body frame. The lower ends of the inclined brackets 19 unite with the rails 14 at short distances from the outer ends thereof, thereby forming angular seats 21 for the upper portions of the'side plates. Integral rails 22 preferably of inverted l..- shape in cross section unite on the

uprights

4, 5, and b and said rails 22 are located at such a height as to occupy approximately the same plane as the belt rail of the car body.

ll/ly improved end frame is preferably castin a single piece and for this reason it can be readily applied to a car under frame and body and considerable time and labor can be saved in the assembling and building up of the end portion of the car body.|

By my improved construction and manner of forming the lower portion of the end frame all shearing stresses are taken off the rivets utilized in fastening said frame to the under frame.

By providing rearwardly projecting brackets at the sides of the end frame and arranging" the same so as to bear directly upon the under frame an exceptionally strong, rigid anti-telescoping construction is provided which in service affords a manimum degree of safety to the occupants of the car during collisions.

lit will be readily understood that minor ipaaeee changes in the size, form and construction of the various parts of my improved end frame can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:
