Specification of Letters Patent.

Patented Feb. l2, ilf.

To all whom it may concern.'

Be it known that I, HARRY H. Scnnornn, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Car-Diaphragms; and l 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 specification.

This invention relates to an improved type of telescoping metallic car diaphragm consisting of only two sections, one of which is rigidly secured to thecar body of a passenger coach and the other of which is adjustably mounted thereon adapted to move inwardly and outwardly and capable of lateral and vertical movements to a certain extent to permit adjustment of the diaphragm to take place when the same is connected to another diaphragm of a car coupled to the car on which said metal diaphragm is mounted. A

It is an object therefore of this invention to provide lan improved diaphragm construction wherein a pair of telescopingsections are operatively connected with one another to permit one of saidsections to move in telescoping relation both over and within the other during contraction of 'the diaphragm.

It is also an object of this invention to construct a metallic car diaphragm consisting of a stationary section having flat vertical side walls and with a hood rigidly seciired thereabove on the car comprising a top member flanged downwardly at its for-v ward end and with another section, the side walls thereof overlapping the exterior of the side walls of the stationary section, and with the top member of the movable section Banged upwardly and adapted to slide beneath said downwardly flanged hood.

It is furthermore an important object of this invention to construct a sealed vestibule car diaphragm comprising astationary and movable section slidably associated with one another and with the parts adjustably associated to permit warping movements therebetween.

Itis finally an object of this invention to construct an improved type of metal car diaphragm consisting of few parts easy to assemble and acting etliciently to form a weather-guarded passageway between two coupled cars equipped with diaphragme so constructed.

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

In the drawings:

Figure l is a fragmentary central vertical section taken through the upper end of a vestibule diaphragm embodying my invention.

Fig. 2 is a detail section on line 2--2 of Fig. l.

Fig. 3 is a detail section on line 3-3 of Fig. l, with parts omitted.

Fig. 4 is a fragmentary detail section taken on line l-l of Fig. 1, with parts omitted and parts shown in elevation.

As shown in the drawings:

rl`he reference numeral l, indicates as a whole a car body on which is secured by means ofrivets, brazing or other suitable means, an angle end beam or plate 2, which arches over the vestibule opening at the end `of the car. A stationary vestibule section is mounted on the car and comprises sheet metal side walls 3, each substantially of Z- section, and a metal top wall or ceiling plate l. rihe top margins of said side walls are flanged inwardly and brazed or riveted to the under surface of the ceiling plate 4, as clearly shown in Fig. 2, affording an exceedingly rigid construction, and the innermost margins of said side walls, as clearly shown in Fig. 1l, are riveted to upright I- beam frame members 5, forming a part of the car end.

A movable section of the diaphragm is provided which is movable with respect to said first mentioned stationary section 3%, and is supported in the usual manner of vestibule diaphragms upon an extensible portion of the car platform. Said movable section of the diaphragm consists of flat sheet metal side walls G, which at their upper ends are flanged horizontally inwardly, as denoted by the reference numerals 7, and an angled or gabled roof member 8, the side margins 9, of which are bent inwardly, is fitted slidably over the inturned margins 7, of the side walls with a strip of sealing material l0, therebetween. The gabled roof member 8, at its forward margin is flanged tionary roof member projectingover said roof member of the movable section, inturned overlapping flanges on the movable section and movable roof member and a sealing material therebetween.

3. In a metal diaphragm, stationary side sections, a stationary roof section, hinged side sections adapted to telescope the stationary sections, a movable roof section, inturned flanges at the end of the movable roof section, inturned flanges at the top of the movable side sections, and a sealing strip between said flanges.

4. In a metal diaphragm, stationary side sections, a stationary roof section, hinged side sections adapted to telescope the stationary sections, a movable roof section, inturned flanges at the end of the movable roof section, inturned ilanges at the top of the hinged side sections, a sealing strip between said flanges, and overlapping upwardly and downwardly directed flanges sey cured to the movable roof sections and the stationary roof section.

Copies of this patent may be obtained for 5. In a metal vestibule diaphragm of the class described, an inner stationary section, an outer movable section adapted to telescope therewith, said inner section com- A prising rigid side walls and a roof member,

said movable section comprising hingedly mounted side walls adapted to slide over the exterior of said stationary side walls, a roof member adjustably associated with the hingedly mounted side walls adapted to slide beneath said stationary hood member, a forwardly downwardly turned flange on said stationary roof member, and an upwardly turned flange on said movable roof member to co-act therewith affording a closure between said stationary and movable roof members.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
