Original application flled npril' 29, 1911, Serial No. 624,166. Divided and this application filed lflpril 11,

' 191a Serial m1. easiesa To azz whom it may concern:

Be it known that I, BOO-NE SON, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain newtand useful Improvement in Combined Car-Body Corner-Posts and Door- Frames, ofwhich the fQllOWiIlg' isga 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 bad to the accompanying drawings,- forming part of this specification, in

a which #929,705, dated August 3, 1909.11 nds of' car the vertically dis- Figure 1. is a perspective view showing the end of a passenger coach or car in dotted lines with my improved combined cornerpcst and door frame applied thereto. Fig.

2 is a horizontal section taken approxif mately on the line 22 of Fig. -1 Fig, is a vertical section taken appr'ognmately on the line 33 of Fig. 1. Fig. 4 is a perspective view of a modifiedform of the combined corner post and door frame.

This invention relates generally to railway passenger cars and more particularly to the -car end construction, my principal ob:

ject being to provide a simple, strong and comparatively light. one-piece structure whichis preferably castvand which-com-' bines a car body corner post and door frame.

A further object of my invention is to provide a car end, frame reinforcing and bracing member that can be advantageously employed inconnection with all types of car bodies for the purpose'of bracing the upright end frames of the superstructure and materially strengthening the ends of the cars, thereby providing a strong, substantial structure which willresist severe end shocks due to collisions and resisting all tendency of the cars to telescope, thus af-' fording a maximum degree of safety to life and property.

In order to overcome the.tendency of car bodies to telescope during collisions various. metal. structures have been, devised a and are at present in general use. which structures 'nclude cast metal underframes, platforms,

ailing-sills and one-piece en'd frames which latter structures are'of the type shown in- Patents #917,716, dated April 6, 1909 and To furtherstrengthen and reinforce. the

V. JoHN- posed end frames applied-thereto so as to reduce toa minimum the'tendency of said the corner of a car body preferably behind or inside the uprightend-frame. forming a part of said car body, and to form with said post a door frame which occupies a position" between the" corner post and-the end of "the buffer beam.

The combined corner post and door frame I herein shown and described is particularly designed for use in connection withcombined double bodybolsters-and platforms of one-piece cast metal end frames of the type shown in'Patents #917,716 and 929,705;

-' This application isv a division of a'nappli- 1911, Serial after more fully described and claimed.

Referring by numerals to the accompanying drawings; 1 designates the car body; -2 the underframe, 3 the platform, 4 the-steps '70 the type shown iii-Patent #774,474, and the 'sists in certain features of novelty her'einj at the sides of said platform and 5 theiend frame, all of which parts are of ordinary well-known construction in the car-'build ers art.

- improved construction as shown com prises an upright or post 6 which is prefer H ably L-shaped in cross section, and when,

said post is applied for use, the inwardly proJectmg' flange 6" occupies a position between the upright .end frame at the car inner or rear faces of the side portions of bodv or superstructure and theien-d portions 2 said upright car'end frame so as to form an effective brace therefor and to distribute over a considerable area of'the side portions of the end of the car body all end shocks 'sectionand when applied for use the hori zontally disposed flange of this rail bears 10cand crushing stresses which may be imofthe post 6 is a horizontally disposedrail 7 preferably of inverted L-shape in, cross directly against the top of the .u'nderframc' 2. Extending from the end of this rail or member 7 to the upper portion of the post or upright 6- is a diagonally disposed brace 8. 4

Formed integral;- with. the upper and lower ends ofthe post or uprightG are upper and lower rails 9a1id 10 respectively, which form the lintel and threshold plates of the door frame. preferably L-shape in cross-section with their horizontally disposed flanges projecting inwardly, and uniting'the outer ends of this lintel vand threshold plate is a vertically disposed post" er upright 11 preferably L-shape in cross section", and said post or upright is fixed to, forms a substantial upright between the endofthe bufiing sill and'the outer corner of the car hood.

' The posts 6 and 11 extend below the plane occupied'by the un'derframe 2 and platform 3 so that the threshold plate 10 arranged between the lower ends of said posts readily combines "with the "lower one of 'thje car steps l. Y

In the modified construction illustrated in Fig. 4, a diagonally disposed bracing member 12 is arranged betweenthe end of the rail 7, and the centralport-ion of the postor; upright 6 and a diagonally disposed member 13 is arranged between the end of the. rail 7 and thelower end of said post br upright 6'. v I

My improved reinforcing and-strengthening structure is preferably cast in a single piece so that it can be readily applied for use and when properly combined with a car body and the upright end fram'e thereof,

said structure provides a yery strong and comparatively light construction which combines with the end frame of ,the car body in resisting all end shocks and stresses due to collisions, thereby minimizing the danger of telescoping of the cars due to collisions while said cars are running at highspeed. w'

The braced corner post '(ibeing positioned to the rear of the car end frame materially strengthens the car end and corner between the underframe' and the superstructure, and by providing the inwardly projecting flanges 6 all stresses and shocks imparted to the upright end frame of the car body are distributed over a considerable area of the car body superstructure.

In practice, I prefer to form the inwardly projecting flange 6 of the corner post substantially wider than the side flange, which angmgement is clearly shown in Figs. 1 an 1 The corner postis further braced against crushing stresses and end shocks by the diagonally disposed bracesbetween said corner post and the end of the rail 7,- and this construction combined with the extra wide flange projecting inwardly from the corner Bothof these members are and bottom members.

post is effective in resisting}{crushing stresses which may be imparted direct to the upright end frame of the car body or superstructure, which end frame, as shown and described, is preferably arranged so that the inner faces of its side edges bear directly against the wide, inwardly projecting flanges 6* of the corner posts.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved reinforcing corner post may be made and substituted for those herein shown' and described without departing f the Spirit of my invention, the scope'of which is in the appended claims. r I claim:
