ALPI-IONSUS I]. DRUM, OF HIGHLAND PARK, ILLINOIS.

SUBWAY CONSTRUCTION.

Application filed April 1, 1913.

To all whom it may concern:

Be it known that I, ALPHoNsUs L. DRUM, a citizen of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Subway Oonstruction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to subway construction.

One of the objects thereof is to provide a practical construction for subways having a capacity for handling extreme passenger trafiic without congestion.

Another object is to provide a subway station of simple form in which the passenger traflic is readily handled Without inconvenience to the passengers and in which the space for the construction is economically used.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possible embodiments of this invention, Figure 1 is a plan of a construction for subways; F ig. 2 is a plan of the station construction of the sub way shown in Fig. 1; Fig. 3 is a cross-section along the line XX of Fig. 1; Fig. 1 is a cross-section along the line YY of Fig. 2.

Similar reference characters refer to similar parts throughout the various views.

Referring now to Fig. 1 of the drawings, there are shown a plurality of through

tracks

1, 1. and 2, 2, the former being preferably used for local train traffic and the latter tracks for express trains. In this figure there are shown, in somewhat diagrammatic form, two consecutive stations, 3 and 4, traversed by these tracks. These stations may be considered representative of a large number through which these tracks pass, and if desired local stations communicating with the outer tracks only may be interposed in the system.

At each of the stations shown there are Specification of Letters Patent.

Patented Aug. 12,1913.

Serial No. 758,100.

provided three island platforms, 5, 6 and 7 serving for the loading and unloading of the trains and positioned at about the floor level of cars on the tracks. The station is provided at a higher level, as best indicated in the sectional views, with longitudinal platforms or walks, 8 and f), substantially registering with the sidewalks of the street above and extending over the outer tracks 1. These platforms are connected by the transverse galleries 10 substantially at opposite ends of the station and a wider transverse platform, or promenade, 11. From the latter platform suitable stairways 12 lead to the station platforms and are protected by rails, gates or other devices, as indicated at 13, to insure prepayment of fare. These Stairways, if desired, may be of the escalator type and similar stairways lead from the island platforms to the upper level, as indicated at 1 1 and 15. These various points of communication with the several island platforms are so spaced in position and so ample in capacity as to insure the even flow of currents of passengers without a tendency to congestion and the proper distribution upon the several platforms.

The

several tracks

1 and 2 extend between the various stations at a substantially constant depth below the street level and thus provide an ample air space and it is to be noted that the platforms 8 and 9 extend continuously from station to station. One advantage due to this construction lies in the convenience to passengers whereby upon leaving the trains they may walk substantially to their destination without inconvenience due to encountering the traflic of busy streets or inclement weather conditions. Another and even more important advantage, however, lies in the following feature: By the construction of station 4:, which is substantially identical with station 3, it will be seen that the passenger tratlic is readily guided between the mezzanine level and the station platform level in either direction. From the above level, however, to the street there would, unless special means were provided, be a tendency to congestion which would be even aggravated by the large passenger capacity of these stations. There are here provided, however, from the longitudinal platforms 8 and 9, as well as

lateral extensions

16 and 17, at the various street corners, a large number of exits 18 whereby the passengers may be received from the street level or discharged thereto at an extremely large number of points. Due to the fact that the passengers are permitted, by the construction above described to walk to their precise destination along the route from the nearest station and even to a point offset from the route by the lateral extensions, the passengers are not discharged through 0011- stricted passages in a highly localized area I but are evenly distributed along the entire route and adjacent sections. In like manner, the entering passengers are drawn from an equally large area through an equally ample number of inlets. v

It is to be noted that if desired the longitudinal or through platforms 8 and 9 may be provided throughout a portion of their width with moving sidewalks, diagrammatically indicated at 19. It will also be seen that by these relatively elevated longitudinal platforms at each station, the necessity for platforms outside the local tracks is done away with, thus permitting the tracks to be properly spread and spaced at each station without reaching the building line of the street. Between stations the tracks may be converged into closer relation, as indicated, if desired. It is also to be noted that the lateral extensions 17 of the longitudinal platforms may be carried a block or more beneath the sidewalks of cross streets, as 20, to another subway, a station of which is diagrammatically indicated at 21, thus providing a covered medium of transfer from a station of one subway to that of another. If desired, suitable gates, as 22, may be pro vided in this extension whereby fares may be collected from pedestrians passing from one subway to the other.

The method of use of the above construc tion has been in large part explained. It

- may be noted that the passengers may enter the system at any one of the various stairways 18 and walk to the nearest station, either by the extensions 16 or through platforms 8 and 9, as may be necessary. At the station, entrance is gained to the island platforms as by the stairs or escalators 12. The discharged passengers are accommodated by the Stairways 14 and 15 and pass through the upper platforms to their destinations.

As many changes could be made in the above construction. and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
