VENTILATING SUBWAYS.

Specicaton o'f Letters, Patent.

Patented April 9, 190'?.

Application iiled May 1,1906. Serial No. 314,679.

To (LZZ whom it may concern.-

Be it known that I, THEODORE D. ROBIN- soN, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented a new and useful Improvement in Ventilating Subways, of which the following is a speciiication, reference being had to the accompanying drawings, forming part thereof.

The object of my invention is to provide a new and improved means Jfor disposing of the vitiated atmosphere and gases in a subway, that is entirely hidden from sight and discharges its vitiated contents at the highest point possible without erecting unsightly means for so discharging it.

Figure 1 shows a longitudinal sectional view of the ordinary entrance-way from the street to a subway, showing the kiosk and housing of the entrance excavation and my means or invention shown in a similar sectional view. Fig. 2 shows a longitudinal sectional view of one of my revoluble transparent shutters; Fig. 3, a vertical sectional view of one end of the housing, taken on line a a. of Fig. 1; Fig. 4, a vertical sectional view of a subway and kiosk, with my invention shown partly in side elevation and partly in vertical section; and Fig. 5, a vertical sectional view of another form of my invention.

The numeral 1 shows the kiosk, and 2 the housing over the entrance, the roof of the housing and sides of the kiosk being of transparent material, as glass, so that the entrance may be more or less lighted by the daylight.

At 7 is seen a ceiling which in part covers the entrance-space, but leaves a considerable space between it and one side of the kiosk, leaving an entrance to the open-sided chamber 10. From this opening and in operative connection therewith drops the conduit 6 and passes longitudinally underneath the roof of the housing and drops again at the rear end of the housing and passes into the subway forming the passage-way 3', thus forming a conduit which receives the foul air and gases in the subway directly under its crown or arch and bynatural draft carries them away, emptying them in the open chamber 10, whence they escape to the atmosphere. This` conduit 6 is preferably made of transparent material and has pivoted portions, as seen at 6 in Figs. 1 and 2, which swing so they may be opened and closed at pleasure, so they may readily be cleaned and then shut again, forming a closed conduit in that portion at least whichreceives the light of the sun, and thus its light is made use of in lighting the entrance-way, kiosk, and housing. That portion of the conduit that lies under the arched roof of the subway has a damper 62 to shut off the action of the draft whenever desired and also has a trap-door dropping downward, as seen at 63, the object being that if a train is passing in the direction of the arrow t the hanging door 63 will direct the forward-moving air into the conduit 6 with more or less force and assist the natural draft already in the conduit, the damper 6z being open. 3 denotes the rear transparent end of the kiosk, 4 the sidewalk, and 9 the earth or ground, and 8 the stairs to the entrance-way. In Fig. 4 is shown how the conduit is brought into the subway and showing it as running along the top of the wall and lower edge orthe arched roof of the subway, and I also show at 64 a branch conduit laid along the arch or the roof of the subway and in operative connection with the conduit 6, discharging its contents into that conduit. There may be as many branch conduits as desired, those over or near to the trains passing over track B and going in a direction to force any pressure the motion of the train may make into mouth b and those trains moving on track A forcing it into mouths turned in the opposite direction to mouth b.

The above construction described so far is intended for subways already constructed but where a new subway is in process of construction then my preferred way of ventilating it is seen at 65 in Fig. 4, which consists of simple conduits rising from the very apex of the roof of the subway preferably, passing preferably under ground to a kiosk and in operative connection with the conduit 6. This construction relieves the subway from containing any part of the conduit. The conduit is hidden from view and can be run any reasonable distance to a kiosk or to any other structure answering the purpose, and in this manner a subway may be fully ventilated.

In Fig. 5 I show that the conduit 6 may be in form of an arch corresponding with the arch of the roof of the subway and may have openable doors 7 the upright part .of the conduit 6 being a part and portion of a kiosk or other appropriate structure, the kiosk not being shown for want of room. The inven- IOC tion as shown in Fig. 4 may be used entire, if desired, or the conduits showninside the subway may be omitted, if desired'. The conduit 6 may take up the whole of the side of a kisok or only a portion, if desired. By my arrangement of my Ventilating apparatus nothingunsightlyis presented in the street,

such as open holes, chimneys, or'other structures that would not only be unsightly, but obstructions to: the streets. By use of that form of my invention shown at 65 i-n Fig. 4 a number of the conduits 65 canI be run to the same kiosk and discharge through conduit 6 the same, wha-t I desire tosecure by Letters Patent is- 1. The combination with a subway and an of the Hight, and a transparent conduit leading from adjacent the roof of said subway upward along the end of said dropped portion, thence horizontally beneath the roof thereof, and thence upward to and through the roof of the elevated portion.

2. The combination with a subway and an entrance thereto havin@P the usual ight of steps, of a transparent housing or kiosk for said entrance comprising an elevated portion over the upper part of said flight of steps and a dropped portion over the lower part of the Hight, and a transparent conduit leading from adjacent the roof of said subway upward along the end of said dropped portion, thence horizontally beneath the roof thereof, and thence upward to and through the roof of the elevated portion, said conduit having its inner wall formed of a series of sections `hinged to swing transversely of the conduit to facilitate cleaning.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. entrance thereto havin@ the usualiiight of steps, of a transparent ousifng or kiosk for said entrance comprising an elevated portion over the upper portion of said' ilifght of steps and a dropped portion over the lower portion l THEODORE D. ROBINSON.
