METAL VESTIBULEDIAPHRAGM.

passenger trafiic is the so-called vestibule diaphragm connected at ealngend of the cars. generally been of the accordion type, which have consisted of heavy ply fabric folded or stitched in variousways to form an expandi'ble structure. It is essential in this type of device that not only a weatherproof construction be provided, but also one not liable to rattle and become noisy when subjected to the hard service required. Heretofore the most successful type of noiseless vestibule diaphragm has been that made of fabric or other similar material, but these have proved expensive to manufacture'and maine tain.

Thisin'vention, however, relates to a telescoping metal diaphragm constructed to be effectually sealed in various positions of adjustment, thoroughly impregnable to the weather, and, as well, operating noiselessly.

It is an object therefore of this invention to construct a telescoping metal car diaphragm embracing metal sections -slidably mounted one upon another and bearing resiliently against one' another upon suitable sealing means So as to permit warping movements ofthe diaphragm to take place Without causing an opening to occur between the It is also an object of this inventionfto construct a car diaphragm comprisin/g a fixed arched section rigidly secured on the end of a car with a larger similarly shaped section fitted thereover and adapted to telel scope thereon, the top 'and side members of said latter member being flexibly mounted, and. having resilient means associated there with to cause 'the same to bear yieldably upon said fixed arched section.

It is also an object of this invention to construct a telescoping car vestibule diaphragm embracing sections interfitting with Specification of Letters Patent. Application led February 12, 1,9154. Serial No. 7,819.

one another and having-'a sea-ling strip inserted therebetween with resilient mechanism for holding the sections associated with said sealing strip compressed therebetween. It is furthermore an important object of this invention to construct a telescoping car vestibule diaphragm made up of metal sections and ywith resilient means associated therewith to hold said metal sections impelled against one another in sealing relation.

It is finally an object of thislinvention to construct an improved type of car vestibule diaphragm consisting of few parts made of metal so as to be impervious to the weather and possessing many advantages of durabilityv over constructions heretofore used.

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

In the drawings: Figure 1 is a fragmentary side elevation partly broken away and shown in section illustrating a car vestibule diaphragm embodying the principles of my invention.` Fig. 2 is a section .taken ona horizontal plane at the end of al Car'with a vestibule diaphragm embodying the principles of my invention'attached thereon.' Fig. 3 is a fragmentary detail section taken on line 3-.3 of Fig. l. Fig. 4 is a detail section taken on -line H of Fig. 3. Fig. 5 isa view of a modification of my invention.

As shown in the drawings: The reference numeral 1, indicates as a whole the end platform of a car having a vestibule platform extension2, andend Walls 3, which extend vertically from the sides ofthe car toward the vestibule extension of the platform in convergent relation. Anl arched opening is afforded between said respective convergent end walls 3, of the car, and secured there` vparts and also insuring silence of operationywsectiiii having an extending flange 5,

saidarched vestibule section 4, is a similarly shaped outer section consisting of a curved top piece 6, and straight side members 7, and joined to said curved top piece 6, are

stiff leather or fabric aprons8, which extend l downwardly and overlap the upper ends of the side members 7 f Said curved top piece 6, and side members 7 are all positively supaov tion.

according` to the portedv upon the face plate 9, of the vestibule, said top and side members being hingedly connected thereto by hinges 10 and 11, respectively. As stated, the ysectional outer telescoping section of the vestibule lits over and around the stationary section 4, and the respective-hinged members of said telescoping section are normally 4 impelled inwardly closely upon and toward said stationary .archedsection by means of springs 12, which are associated with said respective hinged members 10 and 11. Interposed between the spring impelled members 6 and 7,

of the outer vestibule section and the inner stationary section 4, is a strip of felt or other weatherstripping material 13, which may be attached to either one. of the telescoping sections constituting the vestibule, but as' shown is secured near the edge of said stationary arched section on the exterior thereof, thus sealing the space between said respective sliding'sections.

4 In the modification illustrated in Fig. 5, I have shown a stationary vestibule section 19,'similar to the section 4, previously described, and secured -to thexface plate V9, is al resilient plate 20, bearing at its inner end against the ,Weatherstripping element 21, se-

cured on the inner surface of the stationary section 19.

lThe operation is asfollows: The relative movement permitted between the respective stationary and movable vestibule sections is one telescopic in action, but due to the fact that the`movable section 4is made up of a plurality of memberslwhich. are resiliently impelled into-Weathertight contact with the' stationary section, a' certain amount of angular movement is permitted which is neces sarily imposed upon the devicewhen the train is in motion. The vestibule faceplate `upon which the respective .top and side members of the movable vestibule section are connected, affords a substantial support therefor. 'The resilient contact between the movable member and the stationary member of the diaphragm affords not only a weather-tight construction, but also one silent in operation and free from objectionable noise and rattling when the Ytrain is in moof the device constructed The operation modificationl illustrated in 5 is practically identical, that is, a stationary vestibule member is provided which coacts with a movable member.l As shown in Fig. 5, the movable member vis provided with resilient members which bear 'against purpose'limiting the patent granted otherwise than necessitated by the I prior art.

I claim asmyinventionz' 1. In a vestibule .liaphragm of the class described, a statief-ary section, a section tel- ,escoping therewith at top `and sides, and

means holding one of said sections yieldably against the other section'atall points.

2. In a vestibule diaphragm` of the class described, a stationary section,a section tele'- scoping therewith at means holding said against-said stationary section at all points.

3. In a vestibule di'aphragmof the class described, an 'inner stationary@ section, an outer section fitting thereover ati the top. and

the top and sides, andv latter section fyieldably sides and adapted 4to slide thereon, said outer section comprising -a plurality of spring impelled members bearingv yieldably upon the outer surface-of said inner member at all points. 1

.4. In a device' of the class described, the combination with a stationary Asection comprising top and sides, of a similar movable` section intertting therewith,` and hinged connections on the top and side of said movable section spring-pressedto'ward said sta'- tionary section to permit an angular movement between said sections.

5.'In a device of the class described, 'a stationary inverted U section, and a movable inverted U section coacting therewith, said movable section comp-rising top and side hingedly mounted spring-pressed members movable .independently of one another.

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