SYSTEM-FOR VENTILATING TUNNELS.

SPECIFICATION forming'fpart of Y Letters :Patent No. 704,808, dated July 15, 1902. Application inea December 4, 1901. santi No. 84,692." stimati To @ZZ whom it may concern'.-`

Be it known that I, JOHN KRESS, of New Rochelle, in the county or Westchester and State of New York, have invented certain new' and useful Improvements in Systems of Ventilating'Tunnels, VAof Whichthe following is avv tunnel; and for this purposethe invention' consists of a system of Ventilating tunnels which comprises a horizontalpartition formed of stationary guide-plates supported on brack-- ets attached to the walls of the tunneh'springcushioned slide-plates arranged on said guideplates and provided With'contact plateso'rv iianges at adjacent longitudinal edges, keepers for the spring-cushioned slide-plates, an extension-stack for the smoke-stack of thel locomotive, said stack beingprovided with suitableVprotecting-plates where it enters between the contact plates o rL flanges oftlef spring-cushioned slide-plates whenthe train is passingthrough the tunnel, `the spring-U cushioned slide-platesat the ingoing and out'- going ends of the tunnel having adj acentcorners curved outwardly,so as to permit the entrance of the extension-stack, and said springcushioned slide-plates being of suitable length in order to open andV close quickly, so that the,

smoke and noxiousgases which arecoll'ected in the upper section'of the tunnel'cannot escape into the lower part as the extension-stack passes between them.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of a tunnel, showing a locomotive in the same, so as to illustrate my improved system of ventilation. Fig.' 2 is a horizontal section of the tunnel on line 2 2, Fig. 1. Fig. 3 is an end elevation'of 'the tunnel at the left-hand side of Fig. l. Figs. 4 and 5 are vertical transverse sections, respectively, on lines 4 l and 5 5, Fig. 2, showing in part the horizontal partition with the supporting-brackets, the guideplates, and the slide-plates, by which the upper part of the tunnel is shut off from the lower part; land Fig. 6 is a detail perspective v iewgshowing the, connection of the contactianges of Vtwo adjacent slide-plates.

In my improved system of Ventilating tunnels, seas to` prevent the inconveniences arising from the smoke and gases delivered from the locomotive, Idivide the tunnel by means of a horizontal partition-Wall into a larger lower section and a smaller upper section. This horizontal{partition-wall is sufciently high to permitthe free passage of cars through the tunnel. The horizontal partition-Wall is formedof two symmetrical sections which are supportedv bybrackets that are attached at suitable distancesfrom each other to the side wallsfof the tunnel. `Fach section of the hori- .zontal partition- Wall consists of a stationary guide-plate B,which ispreferably sheet metal, attached by screws, rivets, or otherwise to the horizontal arms of the brackets b. On the horizontal guide-plates o are l guided spring-A cushioned slide-plates- @,Which are held in -positiomby means,v of aukiliaryguide-plates jBjthat are made, .likethe stationary guideplates B, of sheet metaland are supported on longitudinal ledges b',that are iirmly secured to the stationary guide-plates B. The auxiliary guide-plates B- are provided at suitable .distances fromeach other with forwardly-projecting keepers B2, Vwhich extend over the spring-ausilionedAslide-plates, so as to prevent ltheraising ofthe same lwhen they are in forward position, said keepers being made in the form* of'rib'ahywhich the strength of the auxiliary guideplates is increased. The transverse edges of adjacent spring-cushioned slide-platesinterlock witheach other, per- Y mitting at thesame time, however, the free lateral movement of the same. Between the keep ers are arranged on the spring-cushioned 95 slide-plates and the auxiliary guide-plates the lugs e, between which and in suitable recesses h2 in the edges of the auxiliary guideplates B (shown in Fig.. 2) are arranged helical cushion-springs f, that serve to return 10e the slide-plates C into their normal position after they have been moved inwardly into the space between the stationary and auxiliary guide-plates. The lugs e and the cushionsprings farepreferablyarranged near the ends of the slide-plates C, so as toimparta uniform pressure on the same. To the adjacent longitudinal edges of the spring-cushioned slideplates C are provided upright contact plates or fianges g, that are pivotally secured to the slide-plates by the centrally-arranged anglebrackets g2 on the contact-plates, and the ends of the contact-plates are connected by the interlocking joints g', as shownin Fig. 6, so that when a pair of slide-plates is moved in lateral direction the jointed ends of the adjacent slide-plates follow the motion of the first slide-plates until direct pressure is exerted on the contact-anges of the second pair of. slide-plates. The slide-plates and their contact-flanges at the ingoing and outgoing ends of the tunnels are rounded off, as shown in Fig. 2, so as to facilitate the entrance of the smoke-stack of the locomotive.

The locomotive L is provided, in addition to the ordinary smoke-stack, with an extension-piece L', which is secured in position by suitable braces Z, the upper ends of'which are attached to a ring-shaped band on the extension-piece IX, While the lower ends are attached in any suitable manner to the frame of the boiler. The extension-piece L of the smoke-stack is preferably provided at both sides with shoes or plates m, which serve to receive the wear incident to the friction of the flanges g, as the extension-stack passes between them. These plates or shoes m are preferably bolted together at the front and rear of the extension-piece L' and can be replaced from time to time as they are worn out by use.

The tunnel is provided at suitable intervals with uptakes U, through which the circulation of air is established from the upper section of the tunnel, so as to conduct olf the smoke and gases that are delivered into said upper chamber from the smoke-stack of the locomotive.

When the train is entering the tunnel, the extension-piece L of the smoke-stack enters between the rounded-off ends of the slideplates C, forces them aside, and then passes through between the contact-flanges of the slide-plates. The slide-plates being springcushioned they close up immediately as soon as the extension-piece has passed one pair of slide-plates. In this manner the extensionpieces leave only a small elongated opening in front or in back of the extension-stack, according to its position relative to slideplates, as shown in Fig. 2, so that comparatively little smoke and gas can pass into the larger portion of the tunnel below the horizontal partition. By the ventilation established in the upper arched chamber of the tunnel by means of open ends and the uptakes arranged at suitable distances the I smoke and gases are gradually carried off, while the cinders are collected on the upper part of the horizontal partition, from which they can be removed from time to time by means of openings formed by removable horizontal plates at certain distances from each other, as shown in dotted lines in Fig. 2.

By the arrangement described the-tunnel can be ventilated insuch a manner that the serious annoyance which is at present experienced by passengers owing tothe obnoxious air in the tunnels is entirely obviated, and likewise the necessity of closing the windows and doors, by which a circulation of the atmosphere is obtained, especially in hot weather, is also dispensed with. My improved system of ventilation can be readily applied to the tunnels at present in use and forms therebya comparatively inexpensive means of removing the objectionable features of the same. The horizontal partition acts at the same time as anoise-muffier, by which the annoyance caused by the rumbling noise of the engine passing through the tunnel is diminished.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination,with a tunnel, of a horizontal partition formed of stationary guideplates supported on the side walls of the tunnel, auxiliary guide-plates, spring-cushioned slide-plates provided with upright contact plates or flanges at their adjacent longitudinal edges, and keepers for said slide-plates, substantially as set forth.

2. The combination,with a tunnel, of a horizontal partition located on the upper part of the same and composed of two longitudinal sections which are formed of stationary guideplates, auxiliary guide-plates, spring-cushioned slide-plates guided by said auxiliary guide-plates, said slide-plates being provided with upright contact flanges or plates at their adjacent longitudinal edges, and keepers proj ecting from the upper auxiliary guide-plates over the spring-cushioned slide-plates, substantially as set forth.

3. The combination,with a tunnel provided with uptakes at a suitable distance from each other, of a horizontal partition formed of two longitudinal sections provided with guideplates and spring-cushioned slide-plates, said slide-plates having upright contact plates or iianges at. their adjacent longitudinal edges,
