. w a 15396357 Specification of Letters Patent. Patented Nov, 1921 g I Application filed April 161' 1920. Serial fio. 874,322. N I i all whom it may concern:
Be it known that I, LEE P. HYNES, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certainnew -andzuseful.
Improvements in Door-Control Systems the following being a full, clear, .and exact dismy invention which I at present deempreferable.
For a detailed description of the present form of my invention, reference maybe had to the following specification and to the accompanying' drawings forming a part thereof.
, more than the other.
My invention relates to the electrical control of doors, particularly a pair of car doors which normally operate in unison,
their door-engine valves being worked by a single circuit. These doors move together to close and drawapart to open. Since .each of them may individually strike an obstruction when closing, such as a belated passenger, they are each provided with a yielding shoe on-its forward edge and either shoe is arranged to reverse the movement of both doors if a passenger, should be hit. 'It may also happen that only one door of the pair will be in use at a time, the other being kept closed and a seat turned down in front of it, or one door of the pair maystick fast and refuse to open or close dr be retarded It is also important that whenashoe yields, it should not act to reverse other doors in the car than the pair to which the shoe pertains. 'It is also necessary in some cases that all the doors on one side of atrain or acertain fraction step therefrom onto the station platform and watch from outside the car the group .of
doorswhich he is closing and then after closing them he can reenter the train and close the excepted door .apart from the 1 others. These and other conditions of cardoor operation are provided-for in the arrangement described and claimed herein.
Referring to the drawing wherein the The two doors move of. which the door-opening which, as the door travels, slide alongein contact with stationary bars or'strips G, F, E, T, R and P are closed, as represented in. the drawing, and all of the circuits are open. The dooropeningwir'e 1, which extends to other doors, will then be connected to battery-H by a switch, such as the push-button O and wire 9,'or a similar distant button 0. Then allof the group of .doors controlled by the wire 1 will be opened simultaneously. At each door, or pair of doors as shown herein, the current will flow from wire 1 by wire 10, back-stop contacts of button Q, wire 4:, short strip P, contact S, short strip E at the left, wire 5, short strip E at the right, long strip F and wire 6, to door-opening valve-magnet 0, goin thence to ground. The valvemagnet 6 will be of the well "known type which requires only a momentary excitation tostart the door engine. Then the engine will continue to operate the door until, at?
the end of'the door run, it'automatically throws it OWIlkViLlVG to door-stopping position readyfor the next trip in the opposite,
direction whenever the door-closing'magnet C ismomentarlly excited. As soon as the .doors start from their closed position, the
contact S at the'left leaves the short strips We may assume that the doors E and P andengages the long strip F, while at the right the corresponding contact S will leave short strip E, but remain incontact with long strip F. The effect of this is to break, at two points in series, viz. at the two strips E,the door-opening circuit I have just traced which includes the wires 4, 5 and 6 and the valve-magnet 0 The lack of symmetry in the arrangement of strips at the right and left sides ofthe doors is for the urpose of producing-at the said contacts 5 and strips ,E the aforesaid two breaks in series, so, ifone door and its contact S 0 should stick and fail to start, or should be d -closing circuit wires are distinguished held .closedfor a long period, the break in the door-opening circuit will still be insured at the othercontact S by the starting of the other door. In like manner when the doors are open contacts W will bridge short strips T and R in the door-closing circuit but will depart from their strips when the doors start to close. It will be evident therefore that the starting of the doors in either direction acts tobreak the circuit which has caused th starting. I a Assuming the doors to be open, 1t is manifest that contacts W have left thelong strips G, G on each side, and now bridge the short strips T and R as aforesaid, while the contacts S are both off from the long strips F. By this bridging of the strips T and R the door-closing circuit, including wires 7 and 8', with the closing valve-magnet C is now complete, and if a current impulse now arrive at wires 7 from theothe'r supply Wire 2 via wire 3, by the closing button which is here shown, or some distant button it will momentarilyexcite the magnet C and start both doors on their closing run. On starting it is obviousthat contacts W leave the short strips T and R and engage the long strips G, while contacts S engage the respective long strips F. By thus leaving strips T and R the doors, at starting,
have broken at their strips, the door-closing circuit which has initiated the start, as heretofore described. It is also clear that each door not only breaks'at starting the valve-magnet circuit which initiated the start, but also, at the end of its run, closes contacts in the valve-magnet circuit which is to initiate the next start in the opposite dlIGClElOIhh Thus in closing, the contact S, by bridging short strips P and E closes conand opening magnet O which is to initiate the next start in the opening direction.
'If the double doors shown herein, are those 'at which is stationed the man who operates the group of doors dominated by wires land 2, or by train-wires connected thereto, it desirable to except these doors from the group operation, and for this purpose I provide the button Q. This button normally bridges at its back-stops a gap in the dooropening circuit through wires 4:, 5, 6 and opening magnet 0, this gap being located between wires 4 and 10 and when opened .by the pressing of button Q cuts off the door-opening circuit from supply wire 1. v This occurs only at this one pair of doors, all others in the group remainin'gconnected to the wire 1 and their opening'circuits subject to current impulses therefrom. Thus the pressing of button Q isolates these particular doors from others in the group. and at the sametime connects battery H directly to the opening'magnet When the train stops at a station, the doorman will press button 0, thereby opening all the doors in the tacts which are in the door-opening circuit It should also be observed that in the event of the door-shoe meeting an obstruction, the consequent closing of a switch D at any door would energize the opening magnets at all the doors in the group, if both contacts S were symmetrically connect- .ed'to wire H in multiple instead of in series,
provided any one door should stick or be kept permanentlyclosed. To avoid that. the
- contacts S are connected in series. as shown herein. by means of the short strips P and E. and wire 5. Hence every switch D. at the time it isconnected to the long strips G and F by means of contacts S and 1V is isolated from the main supply wire 1 and its closure by the door-shoe will energize no openingmagnet except its own. The circuits which are dominated by the respective door-shoe switches D are door-opening circuits branch ing at the point 13 from the door-opening magnet O and including the long strips F and G and the battery H. These may be termed energizing circuits and are both open at strips F and G when the doors are closed tov prevent unauthorized opening of the doors by manipulating the shoes. The strip 'F at the right is kept in engagement with contact S when the door is closed in order to maintain the operating door-opening circuit from the common control wire 1 to the door-opening magnet 0 via wires 4, 5 and 6, but the emergency circuit at the right is still open, when the door is closed, between the cont-act W and the strip G. Vhen either door moves away from its closed position the aforesaid operating circuit is opened, while each door, as it moves away from its closed position, closes the gap in its emergency circuit between G and F, leaving its emergency circuit subject to its door-shoe switch D, until the door is more or less fully opened.
lVhatI claim as new and desire to secure by Letters Patent is:
1. The combination with a pair of doors having a common control magnet. of a yielding shoe for each door, separate branch circuits from said magnet, and switches connected to the two door shoes and independently controlling said circuits.
a 2. The combination with a pair of doors .having a common control magnet and sepaeach door, separate branch circuits from said magnet, switches in the said circuits controlled respectively by the two door-shoes, a control wire extending to other doors, and means for isolating the door-shoe switches from the said control wire.
3. The combination with a pair of doors having a common control magnet and separate engines, of a yielding shoe for each door both shoes controlling the ,Sfild magnet, a control wire extending to other doors, and two sets of contacts between said wire and said magnet, said sets being in series with each other and operated by the respective doors to isolate the door-shoe control from the said wire.
4. The combination with two doors having separate engines with a common control magnet therefor, of a yielding shoe for each door, switches operated by the respective door-shoes and acting on the said magnet, a common control wire extending to other doors, a contact on each door connected to the door-shoe switch and engaging stationary strips which are connected respectively with said magnet and with a source of ouring separate door engines with a common door-opening magnet, of a common control wire extendlng to other doors, an operators switch for energizing said. control wire, an
operatingcircuit between said control wire and said door opening magnet containing contacts which are closed when the door is closed, two emergency door-opening circuits controlled respectively by the yielding doorshoes ofthe respective doorsebut containing contacts which are open when the doors are closed, and automatic means for opening the contacts in the said controlling circuit when either door is opened and closing the contacts in either emergency circuits when its corresponding door is opened.
