3 SHEETSSHEET 3 To allwhomt'tmay cancer 1 r Be it known that I, HARRY'H.'SCHRQYE1,

' a citizen of the United. States, and a resident of the city of Chicago, in the county of 5 (look and State of Illinois, have invented certain new and useful Improvements in Metallic Car-Diaphragms; and I do hereby declare that the following is a full, clear,

and exact description of the same, reference being had to the accompanying drawings,

and to the numerals of reference marked thereon, which form a part of this specifi'cw' tion.

With the almost widespread introduction of steel cars for passenger traffic on railroads, attempts have been made to construct metal vestibule diaphragms for attachment on the ends of the car which may be connected to one another to afiord a sealed weatherproof passage between the cars which are coupled together. Such a diaphragm must not only afiord a weatherproof passage between the cars, but. as well he capable of adjustment due to the severe conditions of usage imposed thereon, owing to relative movement taking place between the coupled cars on which diaphragms of this type are mounted. I a a It is an object therefore of this inventlon to construct a metallic car diaphragm wherein the sides and top arching over the platform extension of the car are constructed of metal, the elements thereof being so designed and associatedwith one another as to permit the necessary ad usting move= inents to take place when relative movements between the cars occur such as in traveling over an uneven roadbed, negotiating curves, or during switching operations.

It is also an object of this invention to construct a metallic car diaphragm comprising metal walls and top members integrally connected to one another and having the face plates sealingly and adjustably mounted thereon, and adapted to telescope within top and side wall members associated with the car to compensate for variations in move ment between the coupled cars on which diaphragms constructed according to the principles of my invention are mounted and connected to one another.

It is also an object. of this invention to construct a metallic car diaphragm wherein the side and top walls of the diaphragm are 55 arranged to telescope with stationary re Specification or hetters Patent. Pafigmtlsfl F H 11% w a li ation filed a i-u 10,1918. Serial he. cares.

1 ceivingmembers-mounted rigidly on the cat g and providedwithsealingmeans and with the face plates of the diaphragm adjustably mounted on the outer end-of said metallic top and side walls for relative movement with respect thereto.

It is furthermore an important ob'ect ofthis invention to construct a metal ic. car diaphragm wherein integral top and side walls are deformed at the1r forward edges to slldably and adjustably interfit with means mounted on a face plate forming a part of the diaphragm to permitadjusting movements of the face plate to take place and furthermore co-acting with sealing means to afford a telescopic connection between the side and top walls of the diaphragm and the main bod of the car to permit extension and contraction of the metallic diaphragm.

It is finally an object of this invention to construct an improved tvpe of metallic car diaphragm capable of extension and adjustment to compensate for inequalities and variations of alinement between coupled cars acting eiliciently to afiord a sealing connection for passage between the cars.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

The end of a car body is denoted as whole by the reference numeral 1, and secured rigidly thereto at the upper end thereof is a horizontalfiat metallic receivin compartment comprising a top wall 2, an a bottom wall 3, with the outer margins of tho top wall 2, turned upwardly at right angles, as denoted by the reference numeral 4, and secured in any suitable manner to the body portion of the car. As clearly shown Y wall 8, and an outer wall 9, integrally conturned outwardly and rigidly secured to nected to one another and with the upper margins of the inner wall 8, turned inwardly and rigidly secured to the bottom wall 3, of the upper horizontal compartment, and the upper margin of each of the outer walls 9,

said bottom wall '3, said bottom wall 3, havinga slot therein, as clearly shown 1n Flg. 3, at the junction of the upright walls 8 and 9, therewith. Angle iron braces 10, are secured to each of the outer walls 9, and to an upright I-beam frame member 11, forming a part of the car body. Inserted into the 0 en end of the compartment afforded by t e walls 8 and 9, are thin metallic strips 12 and 13, having belting or other sealing material 14, thereon.

The telescoping sections of the diaphragm adapted to slide within the side wall and top compartments described, consist of side wall plates 15, adjustably connected as hereinafter described and shown in Figs. 3, 4, and 5, to a top wall plate 16. For this purpose, the upper margins of the respective side walls 15, are turned inwardly at a right angle, and secured on the under surface of the side margins of the top wall 16, are downwardly bent plates 18, to afford recesses to receive slidably therein the inwardly turned margins 17 of the side walls, and a strip of sealing material 19, is secured upon the top surface of each of the inwardly turned ortions of the side wall plates sealing against the under surface of the top wall plate 16. "An adjustable connection is provided for both the side wall plates 15, and the top wall plate 16, at their forward or outer end at the connection thereof to a face plate 20. For this purpose, the forward margins of each of the side wall plates 15, are bent outwardly as denoted by the reference numeral 21, and shown in detail in. Fi 6, and beaded over, as denoted by the re erence numeral 22. Secured upon the rear face of the face plate 20, is ametallic strip-23, with one margin thereof bent outwardly and spaced away from the surface of the face plate to aflorda recess for the reception of. the beaded portion 22, of said side 7 wall'plate,so that "the same fits snugly and sealingly therein and yet said face plate is capable-of angular ad ustment with respect thereto. The top wall plate 16, at its forward edge, is provided with an upturned margin 24, as shown in Figs. 4 and 7 which abuts against a wear plate 25, secured upon the face of the vestibule face plate and en- -I have shown a slightly different construction from that shown in Fig. 6, wherein in place of the beaded portion of the shape designated by the reference numeral 22, in Fig. 6, is shown a rounded almost circular bead 28, formed on the bent margin 21, of the side wall plate.

The operation is as follows:

The side walls 15, and top wall 16, which telescope within the narrow side wall and top compartments secured rigidly on the car body, are sealingly and to some extent adjustably held therein and are capable of adjusting movements, so that the weaving effect which is imposed upon a diaphragm in use is readily taken care of without noise or wear upon the parts. As bufling and draft stresses take place between coupled cars, the respective diaphragm sections on the cars are contractedor expanded, as the case may be, the telescoping elements sliding one within the other. Due to the adjustable connection between the top wall and the side walls of the telescoping sections of the diaphragm, it is p ssible for one side wall to be extended or contracted a greater amount than the other, as for instance when a pair of coupled cars are traveling on'a curved track or in switching, the top wall swinging laterally during'such movement within the top wall compartment therefor, which is considerably wider than the top wall 16, itself to permit such swinging movement to take place. The face plate 20, is allowed to assume angled positions with respect to the telescoping sections of the vestibule diaphragm due to the yieldable connection between the top and side walls and said face plate, and furthermore said face plate is capable of sliding vertically to a certain extent to prevent strain being imposed upon the parts due to the weaving effect imposed upon the connected diaphragm sections of cars coupled to one another. The strips of seal ng materlal shown consist of cotton belting, serving to effect a sealing connecmembers.

aacaoaa the diaphragm is comparatively easy-to manufacture and assemble, and is simple in operation, and damage to any one of the parts thereof may be easily repaired by replacement.

. I am aware that various details of construction may be varied through a wide from the princirange without departin ples of this invention, an I therefore do not purpose limiting the patent granted other-. wise than necessitated by the prior art.
