VENTILATING sYsTEM.

Specification of Letters Patent.

Patented Aug. 71, 1911.

Application led May 29, 1911. Serial No. 630,037.

my object being to enable the window-sashto be utilized as the medium through which to ventilate the car by supplying it with cool, fresh air. i

The invention is.- adapted, however, for interior Ventilating systems generally, where the sash employed for the windows of the inclosure' is hollow.

In the accompanying drawings, Figure 1 is la broken sectional View of a passengercar, showing the interior thereof in side elevation, with two windows equipped with my improvement, the sash of one window being closed and that of the other raised; Fig. 2 is an enlarged section on line 2, Fig. 1, and Fig. 3 is an enlarged section on line 3, Fig. 2. V

While my invention is designed to be employed in connection with any construction of hollow window-sash, I have selected for illustrating it the sash shown and described in Letters Patent No. 977,415, granted to me November 19, 1910, which need not, therefore, be described in detail herein, but the general construction of which may be described as follows:

A suitable sheet-metal blank, for a hollow sash 4 of 'rectangular shape, is bent to form top, bottom and side rails, with a recess 5 about the inner edge ofthe sash for seating trough-shaped rubber cushiol s 6 in which the window-pane 7 is confined 'about its edges, being clamped in place by hollow metal beads 8 fastened in position to bear against the inner ,sides ofI the cushion. The beads, which are also formed from a sheetmetal blank of proper shape, are provided, with tongues 9 to tin inclined sockets 10 formed inv the rails.

The car 11 is equipped with any suitable pipe-system for the circulation of air, that shown comprising pipes 12 running along the sides near the Vfloor of the car and con-A nected under the car seats 13 withlpcoils 14. The pipe-system may be that used 1n .cold

weather for the .circulation of steam to heat the car, to be converted into an air-conductmg system for my present purpose.z

In the sash 3 of each window, or of as many windows as may be desired, is a chamber 15, formed by a flanged plate 16 extending lengthwise through each rail, the 'chamber being packed aboutits walls with a suitable insulating lining 17, preferably asbestos, fto prevent the metal sash from becomlng corroded by moisture in the air.

Perforations 18 are provided through'the inner faces of the chamber for the escape of air from it. 'An air+pipe 19 containing outlet-openings 191 is housed in the chamber 15, and is fed with air from a pipe 12 through j-.a branch-pipe 2() rising from the pipe 12 through the window-stoolf'21 into the pipe 19. The pipe 20, which is shown to be .equipped with a valve 22 for permanentlyopening or closing the supply of air to the sash, also contains a rotary valve 23 for temporarily opening and closing .the same by lowering and raising the sash. To that end the valve 23 has its stem 24 provided with a handle 25 carrying a link 26' on its outer end, which is pivotally connect-v valve 23, the rod terminating at its upper end in a head 30 litting'a recess 31 in the stool when the head is depressed, to countersink it. The head is in the path of the lower sash-rail, Ywhereby when the sash is down to close the window the rod 27 is depressed to open the valve'23 (the valve 22 being normally openvwhen my improved system is in use and normally closed when it is out of use), permitting air to circulate through the pipe 19 to discharge through the perforations 191 into the' chamber 15 and thence out through the perforations 18. Adjacent to the chamber 15 is provided, to extend about its innen face, as usual, a stop 32, which. in the present case is formed hollow of sheet-metal and provided with per# lined about it for raising it to close thev forations 33 through its wall adjacent to buildings.

' may be that in common use for forcing cold -air vinto hotel, theater and. other public .What I claim as new and desire'to secure 1. In combination with an inclosure, a

hollow window-sash forming an air-passage Closed on its outer side and provided with perforations 1n its inner side, and means for supplying cool air to sa1d passage, for the purpose set forth.

,2. In combination with an inclosure, a hollow window-sash forming an'air-passage closed on its outer and provided with perforations lin its inner side, a perforate air-pipe in said passage, and means for supplying cool air to said pipe, for the purpose set forth. p

8. In combination with an inclosu'ie, a hollow window-sash forming an air-passage closed 'on its outer side and provided with perforations in its inner side, a perforate air-pipe in said passage, means for supplying cool air to said pipe, a valve-equipped connection between said meansl and pipe vfor supplying the air to the latter, and a spring-pressed rod connected with the valvestem and ext-endingn into the path of movement of the sash forj'the purpose set forth. 4. In combination 'with an inclosure, a hollow window-'sashl forming an air-passage therein closedo'n its outer side and provided 'with -perforations in its .inner side, a perforate air-pipe in said passage, means for supplying cool air to said pipe, and a hollowl stop for the sash at the inner side thereof having` perforations communicating with v said air-passage in the sash and the inc'losure whereby the cool air from said air-passage enters the inclosure Jehrough said stop, for the purpose set forth.

5. In combination with lan inclosure, a hollow window-sash forming an air-passage therein closed on its outer side and provided with perforations in its inner side, a: perforate air-pipe in said passage, means for suplplying cool air to said pipe, lend a hollow perforate stop for the sash atthe inner side thereof having its perforations in one side registering with those in the sash Land its other perforat-ions opening to the inclosure, for the purpose set forth.

6. In combination with a railway-car, hollow window-sash forming air-passages therein closed on their-outer sid'es and provided with 'perforations in their inner sides, pipes supplying cool-air to the car, perfo-v rate air-pipes in said passages and branchu pipes leading from said airsupplying pipes to said perforate pipes, for the purpose set forth.

7. In combination with a railway-car, hollow window-sash forming air-passages therein closed on their outer sides and provided with perforations in their inner sides,

path of movement of the correspondingsash,

for the purpose set forth. y

8. In combination with arailwaycar,hol

lon7 window-sash forming air passages.` .therein closed on their outer sides and provided with perforations in their inner sides, pipes supplying cool air to the car, perforate pipes in .said air-passages,branch-pipes leading from said. air-supplying pipes to said perforate pipes, and hollow perforated.
