Application filed March 25, 191 6. Serial No. 86,617.

and State of Illinois, have invented certainv new and useful Improvements in Telescoping Metal 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 tothe numerals of reference marked thereon, which form a part of this specification.

This invention relates to an improved type of car diaphragm wherein the parts are constructed of metal and adapted to telescope with one another. Many different types of metal car diaphragms have been constructed heretofore, but in many instances the same have proved objectionable, due to the imperfect seal afforded between the parts as well as the noisy operation of the diaphragm when in use. This invention, however, relates to an improved type of metal car diaphragm wherein the parts interfit to permit expansion and contraction of the diaphragm according to conditions imposed thereon, and with the parts sealingly connected to afford a weatherproof construction and so associated as to permit the adjustments of the diaphragm to take place necessitated by relative movement occurring between coupled cars on which the diaphragms are mounted and connected to one another.

It is an object therefore of this invention to construct a telescoping metal car .diaphragm wherein-the top and side wall members of the movable sections of the diaphragm are adjustably connected to permit relative movement therebetween and furthermore with the face plate adjustably adjustably and'sealinglv connected to one upon the diaphragm when in use, and further with a sealing means mounted upon the car body coacting with movable portions of the diaphragm to effect a seal therearound.

It is furthermore an important object of this invention to construct a metal car diaphragm wherein the face plate is adjustably mounted upon the forward end of the movable section of the diaphragm in a manner to efficiently support the same, and with the side walls of the movable section of the diaphragm adjustably connected to the top wall thereof so that adjusting movements of the face plate to which the top wall is connected and supported thereby, may easily take place.

It is finally an object of this invention to construct an improved type of metal car diaphragm with the parts so associated as to permit adjusting movements of the parts of the diaphragm to care for any conditions of operation, and acting efficiently to perform the purpose.

The invention (in a preferred form) is more fully described.

As shown .in the drawings:

The body of the car, which may be of any conventional type, is denoted as a Whole by the reference numeral 1, and secured thereto and extending inwardly from the end of the car and projecting slightly beyond the end thereof is a plate2, bent to an acute angle or gable shape, as shown in Fig. 8. Also secured rigidly to the car'body in any suitable manner and forming a part thereof, is a vertical plate 3, to which the rear or inner end of the plate 2, which is flanged outwardly for the'purpose, is secured in any suitable manner. A rigid horizontal partition or plate 4, extends transversely across the upper end of the car body upon which the lower flanged margin of the upright plate 3, is secured in any suitable manner. Mounted within the compartment afforded by the gable shaped top plate 2, and bottom plate 4, and upright plate 3, is a compartment member having double top walls 5 and 6, respectively, secured to one another at their forward flanged ends and angled in gabled relation parallel to the top wall member 2, and a bottom wall 7, forming a part of said compartment member is also rovided, as clearly shown in Fig. 1. Extending slidably through said compartment and rigidly held. in the vertical rear wall 3, is a buffer 'rod 8, around which a coiled compression spring 9, is disposed, bcaring at one endagainst said wall 3, and at its other end against the forward end of an extensible section of the diaphragm hereinafter described. The movable or telescoplng section of the diaphragm is ad ustably connected to the face plate of the diaphragm, which is denoted by the reference numeral 10. Said movable diaphragm section consists ofan acute angled or gabled top wall 11, the forward margin 12, of which is riveted to the rear surface of the face plate 10, and the lower or outer margins of WhlCh are turned horizontally inwardly as denoted by'the reference numorals 13. The side walls of the movable diaphragm section are denoted by the refere nce numerals 14, and the upper margins thereof are turned inwardly and hooked up-,

wardly, as denoted by the reference numeral 15, to receive the inturned margins 13, of the top wall bearing thereupon, and said top wall margins 13, are provided with a strip of sealing material 16, which is interposed between the metal marginal portion 13, and the margin 15, of said side walls. Each of the forward vertical margins of the side wall are headed outwardly, as denoted by the reference numeral 17, and fits beneath an mwardly turned retaining strip -18, wh ch, together with a flat bearing strip or wear plate 19, for the beaded end'17, of said side walls, is secured upon the inner or rear surface of the face plate 10.

swinging movement rigid Said beaded ends of the retaining strip or plate 18, are cut away at points in the length thereof, and secured in any suitable manner within the beaded portion of the side walls 14, are blocks 20, which fit. into the cut away portions, so that the side walls 14, are supported vertically upon the face plate 10, and yet the face plateis capable of adjustment with respect thereto.

Said side walls 14, are adapted to telescope within and between vertically disposed

side walls

21 and 22, mounted in upright position in the end of the car, the forward ends of said respective side walls flanged outwardly and the forward end of the. compartment therebetween provided with sealing means 23, mounted on insert plates 24, between which said side walls 14, sealingly extend. The rear margins of the side wall members 21, are flanged over, as denoted by the reference numeral 25, and bent into parallel relation with the side wall members 22, and headed over, as denoted by the reference numerals 26, and fit beneath beaded sealing strips 27, which, together with wear plates 28, are secured upon the rear surface of an I-beam 29, forming a part. of the car body. Said compartment

side wall members

21 and 22, are adjustably associated with the car frame to permit a slight weaving or horizontal swinging movement thereof to take place.

Hingedly mounted in inclined position on the front of the car end above the top wall member 11, are plates 30, the lower ends of which are provided with a sealing strip 31, and springs. 32, are mounted to impel said plates 30, downwardly upon the respective inclined surfaces of said top wall 11, to seal the same and prevent entrance of water, cinders, snow dust, and thelike, over=the inner rear end of said gable top member 11.

As clearly shown in Fig. 1, the'forward end of the slidable'bulfer rod 8, is secured by means of a pin 33, into lug extensions 34,-

provided on the inner rear surface of the are adjustably mounted in the end of the car so as to be capable ofa slight lateral movement, and the top wall member moving between the interior gable top wall member 2, and the gable wail member 5, beneath the sealing means 31, which is slidable thereon. The top wall 11, is not only of gable shape, but converges rearwardly' from the face plate 10, inwardly to its rear margin, as clearly shown in the partial plan view of Fig. 2, so that the top wall member is capable of a 'withtheface in the

respective side walls

21 and 22, which remorse moved inwardly.
