CAR END FRAME.

Specification of Letters Patent.

Patented Dec. 31, 1912.

To all 'whom it may concern:

Be it known that I, HARRY M. PFLAGER, a 1 citizen .of the United States, residing at the city of St. Louis, State of 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 specication, in which- Y Figure l is a .vertical section taken transversely through the platform portion'of a car' underframe, and showing an end frame of my improved construction in elevation. Fig.-2 is a plan view of the end frame. Fig. 3 is a side elevation of the end frame. Fig. 4 is a vertical section taken on the line 4 4 of Fig. 1. Fig. 5 is a horizontal section taken approximately on the line 5-5 of Fig. 1.

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

One of the most important features in the construction ofthe 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 eiectually 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 cars.

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

The principal objects of my present invention are to generally improve the construction of the cast metal end frames disclosed in the patents above referred to, to form braces on the end frame and fix said braces to the under frame in such a manner as to rigidly maintain said end frame in an upright position, and further to arrange and dispose the various uprights, cross pieces and braces forming theend Vframe so as t0 utilize to the 'greatest-possible advantage the strength of the material of which said parts are formed in resisting end shocks and crushing stresses due to collisions.

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

Referring by numerals to the accompanying drawings, 1 designates the under frame, 2 the end sill thereof and 3 the platform casting, all of which parts are preferably cast integral. My improved frame as shown includes a pair of upright members 4 which perform the function of door posts, a pair of side members or posts 5 which perform the function of corner posts and a pair of intermediate upright members or posts 6. All of these posts are preferably channel shape in cross section, although other cross sectional shapes may be utilized, if desired. i

The lower ortions of the corner posts 5 and intermediate osts 6 are united by web plates 7 and thev lower portions of the intermediate ,posts or door posts 4 are united by integral web plates 8 which are cut away as designated by 9 immediately adjacent the lower ends of the door posts 4 in order to accommodate the side rails or members 3B of the platform casting. Formed integral with the lower portions ofthe door posts 4 and projecting inwardly therefrom areweb plates 10. Formed integral with the upper portions of all of the web plates 7, 8 and 10 and projecting rearwardly therefrom is a horizontally disposed plate 11 which is continuous from one corner post 5 to the other and when the e'nd frame is applied to the under frame, this plate 11 rests directly upon top of the end member of said under frame and is rigidly fixed thereto by means of rivets 12er like fastening devices. Rivets 13 or like fastening devices are utilized for rigidly fixing the web plates 7, 8 and 10 to the front wall of the end member of the under frame.

In order to brace and strengthen the door posts 4, the lower portions thereof are gradually widened to their lower ends to form brackets 14, the lower ends of which extend entirely across the horizontally disposed plate 11. Formed integral with the lower portion of each corner post 5 is a rearwardly extending bracket or heel portion 15 the under side of which rests directly upon the corresponding side rail of the under trame. The horizontally disposed base anges 15a of these brackets are rigidly fixed to the under frame by means of rivets 16 or like fastening devices and the rear ends of said brackets bear directly against shoulders 17, which latter are formed on the side rails of the under frame. By the construction just described, the lower portion of the cast metal end frame is rigidly fixed to the under frame and all end shocks or crushing stressesimparted to said end frame 'are ettectually resisted by the bearing of the lower ends of theposts or uprights against the front side of the end sill and by the engagement of the rear ends of the brackets 15 against the shoulders 17. Such construction takes the shearing strain oii' the rivets utilized in fixing the end frame to the under frame and any strains or shocks imparted to the vupper portion ot the end frame and which may tend to swing the upper portion of said frame inwardly will be resisted by the bearing of the brackets 15 directly upon top of the under frame.

The upper portions of the uprights f1, 5 and 6 are united by a horizontally disposed plate 18 which performs the function of a lintel for the door frame, said plate being widest at its central portion and gradually tapering toward its ends. Formed integral wit-h the rear portion of the plate 18 and projecting upwardly therefrom at ypoints adjacent to the upper ends of the intermediate posts 6 are vertically disposed web plates 19 and formed integral with the rear edge of the plate 18 and projecting upi wardly therefrom between these web plates 19 is a vertically disposed plate 20. 'llhe end portions of this plate 20 are widened and provided with openings 21 which are :tor the purpose ot accommodating the bell cords of the train. Formed integral with the' plates 18 and 20, at points inside the plates 19, are webs or plates 22 which are for the purpose of attaching parts of the hood supporting frame work. Brackets 23 u are formed integral with the plates 19 and the outer portions of the plate 18, and the inner ends of these brackets and the upper ends of the plates 19 serve as supports for the lower portion ot the ventilator frame. The side plates 24E of the car body :trame rest directly on top of the uprights or posts 5 and where these plates are in the 'form of channels, as shown, the upper outer corners of the posts or uprights 5 are cut away as designated by 25 to accommodate the outer tianges et said channels.

My improved end frame is cast in a single piece andtherefore can be readily applied to a car under frame and body, and by the use of such an end frame considerable time and labor can be saved in the assembling or building up of a car body. The end frame is rigidly fixed to the under frame byl means of rivets and the construction of the lower portion of the end frame is such that when thesanie is applied to the under frame, all shearing stresses are taken oli the rivets utilized in fastening the parts to one another. By providing the rearwardly projecting brackets at the sides of the end ing collisions is developed at or below the belt rail of the car and for this reason it is especially desirable that the lower port-ion of the end frame be substantially braced and fixed to theunder frame so as to resist to the greatest extent the force of the blows and stresses resulting from collisions. For this reason, l provide the brackets extending rearwardly from the corner posts and unite the lower ends of all of the posts with the webs which bear directly against and are attached to the'end sill of the under frame.

1t will be readily understood that minor changes in the size, form and construction of the various parts of -my improved end trame can be made and substituted for those herein shown and described withoutdeparting from the spiritof my invention, the scope of which is set forth in the accompanying claims.
