To all 'whom t may concern i Be it known that I, PLATO Gr. EMERY, a citizen yof lthe United States," residing in Chicago, in the county of Cookan'd State of Illinois, have invented anew! and `useful Improvement kin vGuard-Curtains (for Vestibule-Cars, of which the following is a specication. n j
This invention relates to guard curtains for vestibule cars to be suspended betweenl the arch-plates of such "cars when coupled together. In the modern practice one of these guard curtains, mounted on a vertical spring roller is suppliedfor each arch plate. to be extended and attached to a hook'on the adjacent arch plate on theneighboring'car when the two cars are coupled together, thus aflording protection to the personandfclothset forth.
ing of passengersl going 'throughthe archplates from one car tothe other.` yAnd the invention consists vrin the meansvl .of/attachment of the curtain to the adjacent archplate at one end and to the `spring roller at the other end, such attachment being-of a simple and durable character, permanently operative, and not lilelyto get `outof order,
all of which will be more fullyl hereinafter In the accompanying drawing, which forms a part of this specification, Figure 1 is a horizontal section taken through one'of4 the curtains embodying any" improvement,
- showing the curtain extended and attached tothe two adjacent arch-plates as when two cars are coupled together; Fig. 2 shows a front elevation of the curtain extended but removed from both ofthe arch-plates;` Fig.
' y 3,-upon a larger scale, is an end View of the spring curtain roller to assist in/illustrating the means of attaching the curtain Vto said roller by the reinforcing loopyFig.
Li,-also upon a larger scale-,I is -a view, partly in section, of thehandlefrfor attaching the curtainr to they adjacent arch plate;
Fig. 5 is a hoiizontal section of the same. taken on the vline 5--5, ofFigfLg-and Figz. shows a modification of the side handle illustrated in Fig. 4.
Referring to the said drawing, the guardcurtain 10, is provided at its freeend with the usual hem, 11, and inclosed rod 12. The handle 13, having the split lugs 14, 14, is rigidly 'secured tol the edge of the "curtain, preferably, by slipping the lugsA over the hem and its inclosed rod and applying rivets 15, 15, The handle, 13, has an opening specification of Leiters patent. ,Patented sept. s, 1914 Application led February 15,1911. lSerial No..608,749.
*gate 17 guarded bya friction device, through .which guarded 'gate' it, is designed thatthe hoolnto bepresently described, may escape when the tension-orpullonthe curtain becomes excessive, thus permitting :the curtain to bel-gathered home by thevspring roller, as forpexample when the cars5are uncoupled and separated. The hook,- attached tothe adjacent arch-plate, is indicated -at 18, and the gatek17, in the handle is made wide enough for the hook to pass out freely ex'- cept for the lfriction guard device, the inner front edges of the opening, 16, being preferably inclined as at 19, to guide the hook k16, extending up.andfdowntoaccommodate f cars with platforms onf diifering levels,ja
tothe gate from whatever position dueto v differing levels oftheplatformsit may happen to occupy within said opening` 'Ihe friction guard consistsy of the springv borne balls or rounded surfaces 20, each housed in a tube or cavity 21,1 and backed by a spring 22 which ymay haveqan adjusting means or screw 23 forregulating the spring pressure. The 'ball shoulderson the mouth of its cavity so'as-to be retainedfromescape, and projects beyond said mouth to engage thehook. Thesetwo spring-thrust balls one at each side of the gate or pass serve to 'hold thek hook until power 'sufficient 'to depress the springsis exerted, whereupon thel hook will crowd through. It vwill -be notedl that this holderis not wholly a spring tension contrivancebut a compound spring' and friction contrivance, that Vit is simplein construction ,and operation, and.. has no part that may easily break under strain.` In the modicationl shown at Fig. v6 yinstead of the f two balls and cavities a single' springthrust round-endfplug coperates with a -stationary i plane surface tov produce a ysimilar result.
.v The other edge4 of the curtain 10, is, or may :be, 'attachedgtothe spring roller, 24, in the usual manner, winding up the spring when the curtain is extended or `unwound, and
windingk up the ycurtain when the spring is recoiling afterthe common fashion of such apparatus. .'Io protect against strains to which, as before indicated, these guard-curtains are often subjected I providea safety loop or loops, 25 of any desirednumber or width, of leather or other flexible material, sewed or otherwise secured to the curtain vat each face ,thereof and passing around the curtain rollervas indicated. It is preferred to have the loop take the strain of the uny 11evr By means ofthe peculiar spring and fric? tion guarded gate or hold for the hook at one end of the curtain and the loop guardved attachment of the curtain tok its roller ati the jother end thereof, all danger of destruc-' tion of the curtain by the strainsthat o,c-; cur, as sometimes happens when the cars are: uncoupled and separated Without unhook-I ing the curtain, is obviated.4 Indeed, With this construction of curtain it isi-quite safeV to let the curtain take care of itself in y.un-l coupling the cars, though to save Wearit: is of course better to unhook the curtain and :tion guarded gate comprising spring-thrust permit it to roll up gently on-its roller.
Having thus described my invention Il claim y 1. A guard-curtain for railway-car vestibules comprising in combination, a curtain' secured at one edge to a spring roller, thel attachmentbeing reinforced by a loop surrounding the roller and fastened to the curtain, a handle secured to the other edge of the curtain and having a spring-thrust friction guarded gate forming an opening in the said handle for receiving, frictionally retaining, and permitting, .upon greater than the normal strain due to the spring in the spring roller, the escape of the holding hook, said reinforcing loop being adapted to withstand abnormal strains and to prevent tearing of the curtain from the roller, vsub- 1 stantially as specified. i
A latching device for railway-car vestibule guard-.curtains which isv adapted to cooperate With a hook,'said device including a handle attachable to the free edge of the u curtain and. extending in -a vertical plane,
said handle having an enlarged` opening through which the hook is adapted to be placed transversely, Vthe opening being provided with a contracted mouth, the opposite edges of which .are movably mounted in a vertical line andl adaptedto separateto release the hook` upon more than normal pull, L
substantially as specified.
3. A latching devicefor. railway-car vesti--V bule guard-curtains which is adapted toco operate'wth a hook, said device including a handle attachable to the free edge of the curtain and extending in `a vertical plane, said handle.- being provided with an enlarged opening adapted to receive the hook transversely therethrough,said opening having a contracted mouth, one edge of said mouth comprising'a spring-thrust member adapted to be moved in a vertical line by the hook to release the latter upon more than `normal pull, substantially as specified.
4. Alatching device for railway-car vestibuleguard-curtains, adapted to cooperate Witha hook and consisting of a handle attachable'to the edge of the curtain, .and provided vWith an opening to receivethe hook, said opening being provided With a friction guarded gate for the release of the hook upon more than'the normal pull, saidfricmembers adapted` to be laterally moved by the hook, and springs engaging said members, substantially as specified.
5.- A` latching device for railway-car vestibule guard-curtains, adapted to cooperate with a hook and consisting of a handle attachable to theedge of the curtain and provided `with an opening to receive the hook, said opening being provided With a friction guarded gate for the release of the hook upon more than normal pull, said `friction guarded gate comprising a spring-thrust surface adapted to be laterally moved by the escaping hook, and means for adjusting the spring-thrust, substantially as specified.`
' 6. Y Alatchingdevice for railway-car vestibule guard-curtains Which is adapted to cooperate with a hook, said device including a handle attachablejv to the free edge of a curtain, `said handle having an enlarged opening through which, the hook is adapted to be placed transversely, the opening having a contracted mouth, said handle having also an inclinedWall 19 adapted yto guide the hook toward said contracted mouth, substantially as specified.
