ELEVATOR RELAY.
- Application filed December 27, 1924. Serial No. 758,340.
This invention relates to new and useful improvements in elevator floor signal systems. The object of the invention is to provide a floor signal system in which means is pro- Vided forcausing a positive operation and whereby failure of the signal lamp to light is eliminated.
OllClllt closing switch is V cation and by reference to the A particular object ofthe invention resides in a novel form of relay for actuating a gravity contact, whereby an ehicient and simple signal lamp.
Another feature of the invention is to provide electrically actuated means for resetting the relays and clearing the lamps. A construction designed to carry out the invention will be hereinafter described together with other features of the invention.
The invention will be more readily understood from a reading of the following specifidrawings, in which an example of the invention is shown, and wherein:
Fig. l is a circuit diagram'of the system,
Fig. 2 is a front elevation of the relay panel,
Fig.3,is a partial vertical sectional View on the line 33 of Fig; 2,
Fig. 4 is a cross sectional view on the line 4-4= of Fig. 2, and
Fig. 5 is a detail'of one of the relays showing the dog just after it is released from the hook. 1n the drawings the numeral 10 designates a panel upon which a plurality of relays are mounted. This panel may be mounted in a box or case 11, which may be disposed in the pent house, elevator shaft or other convenient place. On each side of the panel are mounted electromagnets12, one foreach floor on each side. In Figs. 2 and 8 five magnets on each illustrating five floors, but the number will of course vary with the number of floors in the building. The magnets are superposed. In front of each magnet is pivoted an armature hook 13 upon a screw 14.
, Each hook has on its side opposite from the magnet a notch 15 at the bottom of Which is formed a stud 16. The hook is pivoted at one corner so as to normally swing away from the magnet. s
I For each hook is provided a dog 17 mounted on a pivot screw 18 and its back bevelled at 19 whereby it is reduced to a substantial oint. The point of each dog isundercut to lbrm a finger 20 which engages in the notch 15 on the stud'16. Each finger normally occuprovided for each accompanying pies a horizontal position. Below each dog is a contact pin21. When a magnet is energized it attracts the hook 13 which swings to the magnet thus carrying the stud 16 from under the finger 20. This permits the dog 17 to swing down and rest upon the contact pin 21, as is shown at a in Fig. 2. The lower end of each hook has a bevelled edge 22 and when the magnet is de-energized the hook is freed and swings outward so that its bevelled edge 22 rides up the back 19 and holds the dog on the pin.
For restoring the parts to their normal position a resetting device isprovided for each row of magnets. Each device consists of a vertical rod 23 mounted to slide in angular brackets 24 and 25 mounted on the panel 10. The rod has a collar 26 alcove the bracket 25 and a collar 27 below the bracket. Normall the collar 26 supports the rod on the bracket 25; while the collar 27 limits the upward movement of the rod. Above each rod is an electromagnet 28 supported by a bracket 29. Each rod has a pin 30 under each dog. Thus when one of the magnets 28 is energized it pulls the rod upwardly, whereby each pin 30 engages a dog 1'7 and swings it up so that the finger 20 rides into the notch 15 and engages over the stud 16. When the rod is freed it drops to its normal position. The bevelled edges play an important part and the positive action of the hooks and dogs is of great advantage.
In Fig. 1 is shown a circuit diagram showing push buttons A and B located at each of the five floors. A plurality of signal lights A and B areshown and are supposed to be mountedin the elevator, car. The buttons A are pressed by passengers desiring to go up while the buttons sengers desiring to go down. A main circuit wire C supplies current to one side of each button by a branch wire C; also to one side of each lamp by branch wires C From each up button a wire A leads to one of the magnets 12, the top wire leading to the top magnet on the left hand side. From each downbutton B a wire B 'leads to a magnet 12 on the right hand side of the panel, the top wire leading to the top magnet and so on.
The signal lamps A are for the up si na ls; while the lamps B are for the down signals. A wire A leads from each lamp A to a contact pin 21 on the left hand side of the panel 10. A wire B leads from each lamp B to one of the pins 21 on the right hand side dog 17. At, the, bottom "of the signal lamps.
are switch buttons, E and F respectively, each having one side connected with the circuit wire C by branches C". From the button E a wire E leads to the left hand magneti s which is connected *ith the wire I) bya branch D A wire F leads from the button F to the righthandmagnet- 28 which is connected to wire D by a wire D A'passenger on the second floor wishing to go up pushes the up button A. A signal lamp box'isarranged'in each elevator car connected in multiple withthe relays of thepanel 10. Current; from the wire C passes through the button A on the second floor over wire C thence by wire A 'to the magnet 12 on'the left hand side of the panel 10. The second magnet from the bottom is thus energized, the circuit'being completed over wires D and D.
When the magnet is energized the hook 13 is swung, whereby the dog 17 is dropped on the in 21. The circuit to the magnet is broken when the button is released. When the dog drops onto the pin, the circuit is closed from wire C over wire C to the up lamp A marked from tne 2, thence over wire A to the pin 21 and thence (log '17 over wires D D" and D.
I The signallight signalbox.
If an operator desires to clear the signal or extinguish the lamp or lamps he pushes the button E which closes the circuit from'wire C over wires C .n to the left hand magnet 28 and thence over wires D andD. This enerwill be illuminated at each gizes the magnet'28 which raises theleft hand rod, 23, causing itspins 30'to restore the dogs 17, andhocks 13 to their normalposition.
lf'a passenger on the fourth floor desires to go down he presses the buttonB which closes the circuit from wire C over wires G and B to the right hand'magnet 12 atQl and thence over wires D and 'D; This energizes the magnet w ich' attracts the hook 18 landldrops the dog 17' into the pin 21. The circuit is thus closed fromwire C over wire C through lamp 3 at a and thence over wire B r'to the pin 21 and thence through the dog 17 and the wires D, D and D.
Various changes in the plurality and location of the parts as well as structural changes may be made within the scope of" the appended claims.
TWhatwe cla-im,is: V I V 1, In an elevator sign al'system, arelay for a control panel a semblage comprising a magnet, an armature hoolr'pivoted adjacent the magnet and havingastud upon its outer face and a holding face extending downward from p the stud, a dog forming a circuitcontact and pivotedopposite the end ofthe magnet and having at ts free end'a finger engaging the stud and an upper surface to engage the hold end, a fingerfeng'aging' the stud and an. ii1--- clined upper surface. to support the holding face of'the'hookwhe'n releasedfromthe mag-' net, a circuit contact disposed beneath the dog to retain the same, a resetting magnet, and'an armature therefor having means -to,"engage the free endof' therdog to raise it from the; last mentioned circuit contact into engage} ment with the'studl 3.
