INTERIOR-HEATING SYSTEM.

Specication of Letters Patent.

Application filed February 16, 1911.

To all whom 'it may concern:

Be it known that I, EDGAR M. MATTHEWS, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Interior-Heating System, of which the following is a specification.

My invention is intended for use, more particularly, in railway-cars which are provided with hollow metal sash for the windows; my object being to enable the windowsash to be utilized as a medium through which to heat the car.

The invention is adapted, however, for interior heating systems generally, where the sash employed for the windows of the inelosure is of metal and hollow.

In the accompanying drawings, Figure 1 is a 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.

While my invention is designed to be employedin connection with any constructlon of hollow metal window-sash, I have selected for illustrating it the sash shown andl described in Letters Patent No. 97 7,415, granted to me November 29, 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 ot rectangular shape, is bent to form top, bottomv and side rails, with a seat-forming recess 5 about the inner edge of the sash for seating trough-shaped rubber cushions 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 of the cushion. The beads, which are also formed from a sheet-metal blank of proper shape, are provided with tongues 9 to fit in inclined sockets 10 formed in the rails.

The car 11 is equipped with any suitable heating system of ordinary type, that shown comprising steam-pipes 12 runmng along the sides near the 'floor of the car and connected under the car-seats 13 with steamcoils 14. 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 evtendinflr lengthwise through each rail, the chamber eing packed about its walls with a suitable heat-insulating lining 17, preferably asbestos, to prevent the surfaces of the rails inside the car from becpming excessively hot where passengers might touch them.y Perforations 18 are provided through the inner faces of the chamber for the circulation of air through it. A steam-pipe 19 is housed in the chamber 15, and is fed from a steam-pipe 12, to constitute it a heat-conductor by circulating steam through it, by a branch-pipe 20 rising from .the pipe 12 through the window-stool 21 into the pipe 19. The pipe 20, which is shown to be equipped with a valve 22 for permanently opening or closing the supply of steam to the sash, also contains a rotary valve 23 for temporarily opening and elosin the same by lowering and raising the sas 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 connected with the lower end of a vertically-reciprocable push-rod 27 extending from it through the stool 21, with a spring 29 confined about it for raising it to close thevalve 23, the rod terminating at its upper end in a head 30 fitting 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, whereby when the sash is down to close the window the rod 27 is depressed to open the yalve 23 (the valve 22 being normally open when my improved system is in use and normally closed when it is out of use), permitting steam to circulate through the pipe 19 to heatl the air circulating through the cham ber 15. Adjacent to the chamber is provided, to extend about its inner face, as usual, a stop 32, which in the present case is formed hollow of sheet-metal and provided with perforations 33 through its wall adjacent to the chamber, to register with the perforations 18, and with similar perforations 33 in its opposite wall and top to discharge into the car the air which enters it from the chamber 1'5 and is heated therein by its contained steam-pipe 19.

What I claim as new and desire to secure by Letters Patent is- 1. In combination with an inclosure, a hollow window-sash forming an air passage closed on its outer side and provided with perforations onits innerI side, and means for supplying heat to said air-passage, for the purpose set forth.

2. In combination with an inclosure, a hollow window-sash forming an air-passage closed on its outer side and provided with perforations on its inner side, a heatconductor in said air-passage, and means for supplying heat to .said conductor, for

the purpose set forth.

3. In combination with an inclosure, a hollow window-sash forming an Vair-passage closed on its outer side and provided with perforations on its inner side, a heat conductor in said air-passage, means for supplying heat to said conductor, a valveequipped connection between said means and vconductor for supplying heat t0 the latter,

and a spring-pressed rod connected with the stem of said valve and extending into the path of movement of the sash, for the purpose set forth'.

4. In combination with an inclosure, a

hollow window-sash formin an air-passage therein closed on its outer si e` and provided with perforations on its inner side, a heat conductor in said air-passage, means for supplying heat to said conductor, and a hollow stop for the sash at the inner side thereof havingv perforations communicating with the air-passage in the sash and the inclosure, whereby the heated air is caused to circulate through said air-passage and stop and into the inclosure, as set forth.

5. In combination with an inclosure," a

hollow window-sash forming an air-passage steam-pipes for supplying steam-heat to the car, steam-pipes in said air-passages and branch-pipes leading from said steam-supplying pipes into the pipes in said air-passaves, for the purpose set forth.

In combination" with a railway car, hollow Window sashI forming airpassages therein closed on their outer sides and rovided with perforations on their inner sides, steam-pipes for supplying steam-heat to the car, steam-pipes in said air-passages, branchpipes leading from said steam-supplying pipes into the pipes in said air-passages, a s

valve on each branch-pipe and a sprlngraised push-rod connected with the stem of the valve and extending into the path of movement of the corresponding sash, for the purpose set forth.

8. In combination with a railway car, hollow window-sash forming air-passages therein closed on their outer sides and provided with perforations on their inner sidesz steam-pipes supplying steam-heat to the ear, steam-pipes in said air-passages, branchpipes leading from said steam-supplying pipes into the pipes in said air-passages, and hollow perforated stops for the sash at the inner sides thereof and communicating with said air-passages and the interior of the car,

for the purpose set forth.

9. In combination with a railway ear, hol-` low window sash forming air passages therein closed at their outer sides and pro- Videdwith perforations' on their inner sides, steam-pipes for supplying steam-heat to the car, steam-pipes in said air-passages, branchpipes leading from said steam-supplying lpipes into the pipes in said air-passages,"

valves in the branch pipes, meansfor opening and closing said Valves by closing and opening-the Window-sash, and hollow perforated stops for the sash at the inner sides thereof and communicating with said airpassages and the interior of the car, for the purpose set forth.
