GEORGE WESTINGHOUSE, JR., OF PITTSBURG, PENNSYLVANIA.
SUBWY FOR ELECTRIC CNDUCTORS.
SPECIFICATION forming part Of Letters Patent N0. 434,165, dated August 12, 1890.
Application filed March 15, 1890. Serial No. 343,974. (No model..l i
.To all whom it may concern:
Be it known that I, GEORGE WEsTINGHoUsE, Jr., a citizen of the United States, and aresident of Pittsburg, in the county of Allegheny' and State of Pennsylvania, have invented a certain new and useful Improvement in Ventilated Subways for Electric Conductors, (Case 382,) of which the following is a specication.
The invention relates to the construction of man-holes or junction-boxes of subways or underground conduits for electric conductors.
The special purpose of the invention is to provide a suitable subway or conduit which will be thoroughly ventilated and t-hus kept free from explosive gases which are liable to escape from the pipes conveying illuminating and other gases in the vicinity of the subway.
The invention will be described particularly in connection with the accompanying drawings, in which- Figure l is a cross section, and Fig. 2 a longitudinal section, of a man-hole or junctionbox embodying; the features of the invention. Fig. 3 is a cross-section of a modified form, and Fig. 4 is a plan of the same. Figs. 5 and 6 are similar views of another modification.
Referring to the figures, A represents a suitable chamber or vault ofthe proper size for receiving the conductors or cables of any suitable character, and these may be drawn through the tubes represented at B, and these tubes may terminate in or near the opposite walls-of the chamber A or pass through them, as represented in Fig. 2, as circumstances may require.
The particular method of running the cables or joining them does not constitute any portion of this invention.
For the purpose of keeping the chamber A. well ventilated and dry, it is constructed as follows: Over the vault or chamber there is placed a casting C. This casting ismade with two walls c c2, and it has openings c3 and c4. One of these openings c3 is provided with a lid D, through which openings d are formed for the purpose of allowing'the circulation of air or gas. An inner lid or cover D2 is provided for the openingsv c4 and fits over a suitable iiange e. This lid is provided with openings e, which may be protected by hoods e2 to prevent the water which may pass through the openings cl from flowing into the vault. The
water is allowed to drain away into a basin G outside the vault through an opening F of the casting. The flange e rises above the level of the lower plate, and the space about it forms a triangle communicating with the opening or outlet F. From this basin the water may escape through the pipe g, communicating with a sewer or leading to any other point. Tubes b may extend from the lower wall of the casting down into the vault to convey fresh air thereto. These may project above the lower wall a suliic'ient distance to prevent the water from flowing through the tubes. When these are used, the openings e may sometimes be omitted.
The air may escape from the vault through the passageF and horizontalopeningsf above the plane of the lid D. The casting is made with a projection H, which extends upwaial at the edge of the sidewalk and forms the curb.
In Fig. 3 a modification is shown wherein the solid plate or lid D3 replaces the lid D shown in Fig. l, and the openings e of the inner lid do not in this instance require the hoods e2. In other respects the construction is essentially the same.`
It may be observed that in the construction shown in Figs. l and 2 the Ventilating-opening f may be sometimes omitted, sufficient ventilation being aiforded by the openings d.
In Figs. 5 and (5 there are shown two side vaults K K2, similar to the basin G, but larger, and they are provided with openings closed by the lids D4. From these vaults tubes 7c may connect with a sewer, so that all of the drainage from above the chamber A may be carried oif to the sewer. use which may collect in the vaults K K2 may be removed through the top by removing the lids D4. Y
I claim as my invention- 1. In a ventilated subway, the combination of a vault, a lid therefor havingventilatingopenings, a water shed or drain about said lid,a receiving-basin with which the watershed communicates, and an air-duct extending from above said lid to the external air.
2. A subway-vault for electric conductors, extending through a street, consisting of a chamber, a lid therefor having Ventilatingopenings, a second lid separated from the first by an air-passage, and a horizontal duct bc- The mud' and ref- IOO ncath the curb of the street communicating with said air-passage.
The combination, with the vault A, of the double-wall casting covering said vanlt, the lids D and D2, separated by aun intervening air-space, and the flange or curb Il, in which there are formed one or more openings f substantially as described.
Ll. The combination, with a vault for an electric subway, of a ventilated cover for the saine, a Water-shed about the cover, and the vaults K K2 for receiving the Water-shed from the cover-space.
5. In a Ventilated subway-vault, the combination, with the double-Walled cover having an intervening horizontal air-space, of the upward] y proj eeting; Ventilating section Il, having the lateral openingf.
