Application filed September To all whom it may mean,-

Be it known that we, FRANK Hnnusr and JAMES S. DOYLE, both citizens of the United States, and residents, respectively, of Ionkers and Mount Vernon county of Westchester, ,State of New ork, have made a certain new and useful Invention in u tiple-Unit Door-Control Arrangement for Cars, of which the following is a specification.

This invention relates to multiple unit door control for cars such as are employed in street, elevated, and subway systems.

' vide means the accompanying The object of the invention is to provide an arrangement for simultaneously or selectively controllin the door movements of a car, or train 0 cars, which is simple in structure, eiiicient in operation, and economical of manufacture, installation and maintenance.

A further object of theinvention is to prowhich are'simple for effecting selectivity of control with regard to the sides of the car on which the door control is effected. l

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination,1'locatio11, and relative arrangement of parts, all as will he more fully hereinafter set forth, as shownhy drawing. and finally ointed out in the appended claims.

Referring to the drawing:

The figure is a diagrammatic view of the system embodying our invention diagrammatically illustrating the circuital arrangement employed in accordance therewith.

It is among the special purposes of oun present invention to provide a simple arrangement for controlling the door movements on a car or train of cars from the station where the car or train of cars comes to rest to thereby eliminate the necessity of having a conductor or other operator stationed on each car to open and close the doors thereof, and making it' possible to have one operator to simultaneously effect the actuation of the doors on all of, the cars where a train isemployed or to selectively effect the actuation of the doors on any one car of the train. We further propose, in accordance with our present invention, to provide means for automatically rendering op ,erative the control system only for the doors on the sideof the car from whioh'it is de- Bpeclflcation 01' Letters Patent.

Referring to the drawing: We have shown diagrammatically the cars 1, and wh le we have shown and will now describe a tra1n compr1s1ng a plurality of cars of any desired number we wish it to be understood that we do not desire to be limited or restricted in this respect as the system is equally well applicable to a single car sys tem. Weprovlde a contact rail 2 adjacent or between the tracks or located upon the track ,bed of the railway s stem, which con tact rail 2 may as the position of the car when coming to rest is always the same at the station, and one contact rail 2 is provided for each car of the train. We aso provide a shoe 3 which shdabLy contactswlth the rail 2 when the par is at the station, and which shoe is in circuital connection with the switches 3,

These switches when in the position shown by dotted lines in the drawing establish circuital connection between the shoe 3 and electrical devices 6, which electrical devices mav be of any nature, for example, magnet valves such as'are commonly employed in door operation for controlling the door movements whereby when the devices G are energized the doors which they control are caused to assume their closed position. Such an arrangement is well (DOWII in the art whereby the devices 6 are in the nature of,magnct valves and will hereinafter he so termed for controlling the supply of fluid pressure and exhaust thcrcof from the usual wellknown type of pneumatic motor at present employed in door actuation on car systems of this nature. The switch 4 when the position shown in full lines in the drawing establishes circuit connection from shoe 3 to wire 7 whic communicates with all of the magnet valves 8, which, when energized, cause the respective doors to assume their open position. The switches 3 4 and 5 are of the usual type which are thrown when the door completes its closed or its open position. in other words, when the door assumes its completely open osition the switches are in the position shown by dotted lines and when the doors assume their completely closed osition the positions are shown by the full ines of the drawing. From the foregoing it will be seen that when current is supplied to the the position shown in full lines all of the Many bther modificationsand changes in magnets 8 will be ener iced; tllereby op'endetails wixl readilyioccur to those skilled in in all the doors on that side of the car. the art w thout departing from the spirit en the doors assume their fully opened and scope (it our invention as defined in the position the switches 3, 4 and 5 assume claims, andl many other arrangements will their dotted line positions so that current suggest themselves for accomplishing the may be supplied at will to the closing magpurposes of this invention, and we therefore net valves 6 to efi'ect the closure of all of desire to have the foregoing specification the doors on that side of e car.
