Specification oLLetters Patent.

Application illed February 15, 1908. Serial No. 416,070.

Patented Aug. 3, 1909i To all 'whom/it 'may concern:

Be it known that I, HARRY M. PFLAGEma citizen'of the United States, residing at St.

Louis, in the State ofMissouri, hays invented.y anew and useful Improvement in Oarl'rameaof which the following isa speciiication.

My invention relatesl particularly to the end framework of arailroad' oar, and has for its object to provide a strong, rigid, and durable metallic end frame specially designed to resist abnormal shocks and telescoping, to form a brace to the longitudinal members of' the car body, and to transmit the end stress uniformly therethrough.

It consists in-features of novelty as herein\v after described and claimed, reference being had to the accompanying drawing forming part of this specification, whereon,

Figure 1, 1s a frontelevation of `my im'- proved end' frame; Fig. 2, aside elevation thereof; Fig. 3, a top plan of the-same; Fig;

` 4', a horizontal seftion through the frame on line 4, 4, in Fig. 1, and Figs. 5, 6, and.7, views corresponding to Figs. 1, 2, and 4, respectively, showing a modification of the con-A struction. v

u-Like letters and numeralsof reference denote like parts in all the gures.

a represents my improved-car end frame,

which is preferably, vcomposed. of cast steel integral t roughout (but may be built up of separately formed pieces) and ycomprises'l preferably, a Ibottom horizontal yplate 1 which extends across 'and'bears against the top (or underside) of the end sill 2 and longitudinal sills 3y and 3 of the underframe at and for. a suitable distance rearward from the outer face of the end sill 2, and a top horizontal plate Afextending across the car body and" bearing a ainst the endv ortions of the side framing ates 5 preferab y on their underside, the p ates 1 and 4 being fixed to the sills 2, 3, and, and side framingplates 5 res actively, by bolts 6 (rivets, or otherwise).

he to and bottom plates 1 and 4 are connecte to each otherby a suitable arrangement of members which are adapted to span. and form the end' framing of the ear body in lieuof the' ordinary supportin wood end and corner posts, door posts and tels, endend transverse timbers thereof, andy con# sists inthe present case, preferably, of a bottom horizontal member 7 which unites with the bottomrplate 1 along its front edge in aV vertical` plane or at right angles thereto, and bears against the front side ofthe end s'lll 2, and a horizontal top member 8 arranged in the plane of the bottom'member 7 and inter- .secting the top plate 4 atright angles theretion of the topplate 4 profecting outward from the top member 8 over angs and forms a braeeto the end of the car body thereat' and through this overhanging portion i formed an opening 4 for receiving the bolt or pin lfor carrying the vestibule; diaphragm f equalizer (not shown).

The members 7 and 8 lare connecte-d to eachother at their middle part by two opposite upright L-shaped members 9'(one onv each side of and at an equal distancefrom the longitudinal center of the car) which are ada ted to form the posts of the door-way 10- of t e car, one leg of each member Qfbeing in the plane of the members 7 and' 8. and its other leg uniting at the top with therib 8 of the member 8 and. formed at the bottom with a reinforcing brace 9 which extends rearl"ward for a suitable distance across and unites with the bottom'. plateM 'lbnctllermore, the members 7 and Sfaireconncted to each other at each side of the car body by an upright channel-shaped bracket 11 having its web 11 arranged inward and having preferably, a double flange at one side in the plane lof the members 7 and 8, the web 1 1 uniting at the top with the top plate 1 and formed at the bottom with a preferably, gusset-shaped brace 11, which extends rearward across, and unites with the bottom plate 1, immediately over the outer longitudinal' sill 3, or thereabout, and end-sill 2 thereat, the other 'Hangs of the bracket 11 conforming thereto.

ach upright member or door post 9 is connected at its u per part to the correponding sidebrac et l1V at the function ereof withthe bottom plate 1, y a T- sha ed diagonal member or brace 12 having its anges in the plane of the top and bottom members 7 and 8, the whole forming a strong and 'rigid metallic structure adapted to tie the longitudinal members of the car body together and to shield and protect the interior of the car, by intercepting, diverting, and

transmitting all end vshocks; thereon directly through .the said members; also, by this construction incase of' collision when one car rides over the platform of the other, the telescoping of the cars Will `bee-resisted by the frame, and'especially by the bottom reinforcing brackets 9 and 11".

Figs. 5, 6, and 7, show my improved end frame a. built up of separately ilormed plates and commercial sized rolled bars in lieu of an integral casting',` but is otherwise substantiallythe same in generalconfiguration and disposition of itsmembers as the frame -preyviously described and shown in Figs. 1` to 4.

. I do not limit myself to the particular shape and arrangement of the top and bottom plates 1 and 4 and their connecting members if, 8,- 9, 1l, as these obviously may be modiiied in various vv ays for eiecting the principle f my'invention.A I am aware also that-metallic membershave been'used in the construction of theendsof car bodies, but they ,areffunctionallyV dependent upon thelr combination `with otherv independent4 parts and do not constituteafunetional unit as inmy-l v top member and adapted to bear a ainst the `underside ofthe vside framing (p l right members connecting the sai horizontal members together, and means for fixing theA ates, up

end frame to the underframe and side fram- "iig plates, substantially as described.

R 2. metallic end frame for a railroad car, comprising a horizontal bottom member eX- tending across and'adapted to bear against' the'end of the underframe, a metallic plate projectingsrearwardly from the said member and. adapted to bear against the longitudinal sills of the underframe, a horizontal top member. extending across and adapted to 'bear against the ends ofthev side framing plates, a metallicy plate projecting rear- Wardly from the said top member and adapted to bear against the underside of the slde fnaming plates,l upright members connecting the' said horizontal members and metallic plates together, and means for fixing the end frame to the underi'rame and sideframing plates, substantially .as described.

.3. The combination with a metallic end 4-frame for a railroad car, of a horizontal member projecting rearwardly from and'ex- Atending entirely across the said frame, and

adapted to bear against the underside of the side framing plates of the car, and means for fixing the said member to the said plates, substantially as described.

4. The combination with a metallic end frame for a railroad car, of a horizontal member projecting rearwardly therefrom and adapted to bear against the' sills of the c ar underframe, and a suitable member unitingl the said .frame' and'horizontal member to ether, substantially as described. y

n testimony whereof I have signed my name to this specification in the presencecf two subscribing Witnesses.
