T o all whom it may concern.'

Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residing at the city of St. Louis, State of Missouri,have invented'a certa-in 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 an elevation of a car end frame of my improved construction, the same being shown as applied to the under frame. Fig. v2 is a plan view of the end frame. Fig. 3 is a side elevational view 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 on the. line 5--5 of Fig. 1.

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

One of the most important features in lthe Way cars, and particularly those cars utilized for transporting passengers, is the reinforcing of the ends of the cars so as to provide an exceptionally st-rong, rigid construction which will eectually resist crushing stresses delivered to the ends of the cars, consequently overcoming the tendency of the cars -to telescope in case of'collsions, andv affording the greatest possible ldegree of safety to the occupants of thecar.

My improvement contemplates a comparatively light weight, strong and durable onepiece cast metal structure which is formed and braced so as to efi'ectually resist end shocks and crushingIv stresses imparted to the ends of the car, thereby providing a construction which is anti-telescopic ineffect.

The principal objects of my invention' are to generally improve the construction of cast metal end frames disclosedin the patents above vreferred to, to arrangeanddispose the various uprights or posts Or cross pieces and braces forming the end frame so as to utilize to the greatest possible advantage the strength of the material of whichsaidparts are formed in "resisting `end shocks and crushing stresses due to collisions, and further to construct a one-piece end frame which can be advantageously employed in connection with composite cars having blind ends. f l

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

Referring by numerals to the accompany' ing drawings, 1 designates the car under frame and 2 the end or buiiing sill thereof which parts are preferably cast integral.

My improved end frame, as shown, includes a pair -of upright members 3 which perform lthe functionf'door posts, a pair of outer members 4 which perform the 'function of cornerposts and a pair of intermediate members 5. These uprights or posts may be` of any desired cross sectional shape although, as shown, I prefer to make the corner posts 4 `of Z-shape in cross section, the intermediate posts 5 channel shape in cross section, and the door posts 3 of Ij-beam shape in cross section and said door" posts are `substantially wider than the intermediate posts and the main body portions of the corner posts. The lower ends of the posts or uprights 4 and 5 are united by L-shape members 6 and the lower portions of the posts or uprights 3 and 5 are united by horizontally disposed plates 7 which` are substantially wider than the members 6 in order to conform to the width rof the posts or uprights 3. y 4 Formed integral with the front edges of the plates 7 and with the front flanges of the posts l3 are depending flanges or plates 8 which, when the frame' is properly applied to the bufling sill, occupy positions 95 against the front faces of said sill.

` Formed integral with the lower portions Of the pair of posts 3 is an L-shape late 9, the horizontal flange of which rests irectly on top of the builing sill 2 and performs the .v1.00 function of a threshold plate ofthe door frame.- The end frame is rigidly fixed to the buling sill by means of rivets 10 or like fastening devices which. pass through the` parts 6, 7, 8 and 9 and. the corresponding 105 parts of the bufling sill. The lowerportions of the corner i osts v4 are extended rearwardly to form rackets Or'heel portions 11, the horizontally disposed base Han es 11l of which rest directly upon the en s of Jthe U0 buliing sill and these parts are rigidly fixed to one another by means of rivets l2 or l1ke fastening devices which pass through the said base flanges. The rear ends of the brackets or heel portions 11 bear dlrectly against shoulders or lugs such as 13, whlch latter are formed on the side members of the under frame 1. The vertically disposed plate 8 bearing against the front side of the buflng sill and the rear ends of the brackets 11 bearing against the shoulders or lugs 13 relieve all shearing stresses from the rivets utilized in rigidly lixing the end frame to the under frame. The upper, outer corners of thecorner posts 4 are notched or cut away as designated by 14 to form shoulders or seats adapted to receive the side plates of the car body frame. Horizontally disposed rails 15 preferably of inverted L-shape in cross section connect the upper portions of the posts 3, 4, and 5 and the posts or uprights 3 extend a short distance above the inner ends of these rails 15. Connecting (the upper ends of thel posts or uprights 3 1 s an inverted L-shape member 16, the horizontal vflange 16 of which performs the function of a lintel for the door frame.

Formed integral with the rails 15 adjacent to the upper ends of the uprights 5 are vertically disposed members vv17 which serve as means for attaching the lower ends of the ventilator frames and integral with these uprights and with the rails 15 and upper ends of the uprights 3 are web plates 18 provided with Vopenings 19 which latter are for the purpose of accommodating the train bell cords. Angular brackets 20 are formed integral with and extend from the upper portions of the uprights 17 downwardly to points on the rails 15 adjacent to their outer ends and the shoulders 21 formed between `the lowerv ends of said` angular brackets and the ends of the rails 15 serve as seats for the upper portions of the side plates of the car body frame. Horizontally (usposed rails22 are formed integral with the posts or uprights 3, 4, and 5 in approximately the same plane with the belt rail of the car body.

My improved end frame is cast in a single piece and can therefore be easily and quickly applied to the car under frame and body and by the use of such end frame considerable time and labor can be saved in the assembling or building up of the end portions of a car body. -r l The construction of the lower portion of t-he frame is such yas to eliminate all shearing stresses upon the rivets utilized in attaching the nd frame to the under frame and 'the rearwardly projecting brackets at the sides of the end frame provide substantial braces which bear directly on top of the under frame, thereby resisting any tendency of the upper portions of the end frame to swing inwardly as a result of end shocks or stresses delivered to the upper portions of said end frame. The central portion of my improved end frame is materially reinforced and vstrengthened by providing the extra wide uprights or door posts 3 and this arrangement, combined with the forming of the entire end frame in a single piece provides an exceptionally strong, rigid antitelescoping construction which in service affords a maximum degree of safety to the occupants of the car during collisions.

It will be readily understood that minor 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 accompanying claims.

I claim:

1. The combination with a car underframe provided with shoulders on its side sills, of cast metal end frame comprising a series of uprights, the central pair of which are substantially wider than the others, the lower rear corners of the outer pair of which uprights bear against the shoulders on the side sills of the under-frame and vertically disposed plates integral with t-he lower ends of the widened central which plates bear against the front face of the buiing sill of the car under frame.

2. The combination with acar underframe provided with shoulders on its side sills, of a cast metal end frame comprising a series of upright members, the central pair of which is substantially wider than the other uprights, web plates integral with and depending from the lower ends of the widened central pair of uprights for attachment to the buing sill of the under frame, and brackets integral with and projecting rearwardly from the lower portions of the outer pair of uprights, the rear ends of which brackets bear against the shoulders on the side sills of the underframe. 3. The combination with a car underframe rovided with shoulders on its side sills, o a cast metal end frame comprising a series of uprights, which is wider than the remaining uprights, horizontally disposed plates connecting the lower ends of said uprights, and brackets integral with and projecting rearwardly from the lower portions of the outer pair of uprights, the rear ends of which brackets bear against the shoulders on the side sills of the underframe.

4. The y.combination with a car underframe provided with shoulders on its side sills, of a cast end frame comprising a series of uprights, the central pair of which is wider than the remaining uprights, horizontally disposed plates connecting the the central pair ofv pair of uprights lower ends of said uprights, brackets integral with and projecting rearwardly from the lower portions of the outer pair of uprights, and rails integral with and connecting the upper portions of said uprights, the rear ends of which bracket-s engage the shoulders on the side sills of the underframe.

5. A car end fra-me constructed in a single piece and comprising a pair of comparatively wide uprights which are of I-beam shape in cross section and serve as door posts, a pair of corner posts, rearwardly projecting brackets integral with the lower portions of said corner posts, a pair of intermediate posts, horizontally disposed plates connecting the lower portions of said posts, horizontally disposed rails connecting the upper portions of said posts, a threshold late connecting the lower portions of the goor posts and a lintel connecting the upper portions of said door posts.

In testimony whereof I hereunto aix my signature in the presence of two witnesses, this 2nd day of April, 1912.
