UPPER UFFING MECHANISM FOR THE DIAPHRAGM FACE PLATES OF VESTIBULE RAILWAY COACHES.

Application filed January 10, 1927. Serial No. 160,061.

- This invention relates to an improvement in an upper butling mechanism for the diaphragm tace plat-es of vestibule railway ci'iaches, and has for its primary object the purpose of providing an improved resilient operating device.

Another object ofthe invention in pro-` viding a bu'liing mechanism with a swivel action so that greater resilient flexibility is given thereto and to the diaphragm to which it is attached.

.il further object of theinventionis in providing a builing mechanism ot a pair of toldable pushing elements.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings, exempllrying the invention, and in which Figure 1 is a plan view partly in section of adjacent ends of a pair of coaches having this improved butling mechanism attached to the end of one of the coaches and the diaphragm.

Figure 2 is a vertical section taken approximately on the line II-II of Fig. 1.

Figure 3 is an enlarged horizontal section of the butling mechanism showing it secured to the diaphragm and to the end of the coach.

Figure 4 is a fragmentary end view of a coach and the diaphragm iace plate thereof.

teterriug by numerals to the accompanying drawings 1 and 2 designate respective coaches and disposed between the ends ot said coaches are a pair of diaphragm face plates E5 and 4 respectively and located beneath the platform 5 of each coach is a pair of horizontally disposed pushing bars 6 each of said pushing bars being adapted to be moved outwardly by a coil spring 7 which is mounted on each of said bars, each of the springs 7 is adapted to engage at one end against a collar 8 which is rigidly secured to each bar G whereas the opposite end of each spring is Aadapted to engage against a cross member 9 which is mounted in each coach. The springs 7 each tend to push a respective bar 6 outwardly.

Each of the bars 6 at their extending ends are pivotally secured at 10 between respective pairs of ears 11 which are horizontally extended from a pair of angle members 12, one of the members 12 being transversely secured to the diaphragm face plate 3 whereas the other member 12 is transversely. secured to the diaphragm face plate 4 at the lower ends oi said face plates. f

Each coach provided with a pair of doorposts 13 and secured to each post and to the side portions jlelol each of the diaphragm iace plates il and l is a foldable material 15, such as fabric, the 4foldable materialextendmg upwardly the approximate height of `each of the diaphragm plates and joii1ing.with transversely disposed` portions of material 1G which are secured between the upper portion 17 of each diaphragm face plate and the car ends as designated at 18 in Fig. 2. Secured to the upper portion or cross member 17 of each of the diaphragm face plates 3 and a is a bracket 19 and formed on each bracket are horizontally disposed pairs of ears 20 and pivotally secured at 21 between each pair of ears is a push rod`22, each of said push rods being oppositely disposed and are each mounted in a respective cylinder 23 each of said cylinders having an end wall 24 through which the extending end of a respective push rod is passed and mounted oli each extending push rod end is a holding nut 25.

Each of the cylinders 23 at its closed end is provided with a lug 26, eachof said lugs being pivotally secured on a pin 27 of a respective bracket 28, said brackets being secured to the respective ends of the-coaches 1 and 2.

Each of the push rods 22 is provided with a rigidly secured collar or shoulder 29, each ot said collars being disposed in a respective cylinder 23 and are adapted to slightly engage the interior wall of said cylinder, and.

mounted on each rod 22 of each cylinder is a coil spring 30 each ol saidsprings at one end adapted to engage the end wall of Ia respective cylinder whereas the opposite end of each of said springs is'adapted to bear against a rgspective collar 29 of each push rod 22.

Each angle member 12 of each coachl is 1ocated outwardly of each cross sill 31, and secured to each member 12 is a horizontally disposed apron 32, each apron at one end resting on the platform 5 oi each respective coach.

Then a pair of coaches are coupled together as shown, the diaphragm face plates 3 and el are held in abutting relation by reason of the action of the springs 7 on respective push rods 6 and the springs 30 on the pushing rods 22 and in which the foldable connecting material between the diaphragm face plates and respective coaches wiil be expended thereby providing,` zi cioeed paesuge between the coaches.

Virhen ceaci which are mounted together as described are being traveled, there is een- Siderable shifting' displacement given hetWeen the ende et coaches hy reefeen oi the action of the drew-heed springe et the couplings and therefore a continued ief 2.3' is carried on in the willie et the ineterizri let and 16 which provides e pesenge-Wey he- Vtween the elo-arches and hy reason ef the diri` phrzizbin trice pietes` 3 und i being of eoneidereine height the iexing nieren much greater adjacent the ippe-r emits of the iiei e plates; by reason of the ervingir cei Vter et the couches being' much lower. i t iis reef-ren :der i applicants improved herring .mechanism is xihihty provided, because :i greeter reeii r 'f eiwn et the upper erich; et the empi regine eeuson et the push rede .tfein` oidirhie inasmuch as they slide within respective eyiinde In th-le cenneetion Athe Swing*- ing eyiindere pei-init the diaphragm fece piates to he moved towards er ewa-y frein the ceech ends es Weil :is perm-itt'ng` the finie @es e 1arte-ral Swingtherehy preventing the i'fzree piates particularly rt the upper ends iiroin gapping apart.
