Doors 57 and 58 have attached thereto a pair of straps 59 and 60 one above the other: adapted to-coincidently close the doors irrespective of a slight variation in adjustment of the rods 5 and 6.
An electric lamp 61 is mounted on the housing 1'7'as indicated and is adapted to be lightedwhen the doors 57 and 58 are fully opened, and remain lighted until the doors are fully closed.
' The wiring of thecircuit is indicated. in the wiring diagram Figure 9 in which 62 and 63 indicate the input power lines. The motor armature isindicated by character 44A, the motor field by 44F. Afour point snap switch 64 is provided at some desired point, as inside the & building, and a three point switch 65 with means for locking in open circuit is provided outside the building. The combination of switches may be extended as desired for control of the device from various locations.
Thermostatic switch 53 is normally retained with the circuit closed, as indicated. With triple pole double throw snap switch 52 shorted across contact points 66 and 67, 68 and 69, .70 and 71 and switches 64 and 65 in the positions indicated, the field circuit is from power line 62 through field 44f, wire 72, switch arm 65, wire 73, switch arm 74, wire 75, contact 70, switch arm 52c, contact 71, wire 76, thermostatic switch 53 to power line 68.
The armature circuit is from power line 62 through wire 99, contact 69, arm 52b,contact 68, wire 77, brush 78, armature 44a, brush 79, wire 80, contact 66, arm 52a; contact .67, wire 81, and thence with the field circuit through wire 72 and switch 65. 1
The lamp circuit is from power line 62 through wire 99, wire 82, lamp 61, wire 83 to wire 84, the circuit of which is broken at both contacts 85 and 86, consequently the lamp will not be lighted. As the doors reach full open position, switch 52 is reversed, the field circuit being broken at contact 70, the armature circuit reversed, and lamp circuit completed through line 62, wire 99, wire 82, lamp 61, wire 83, wire 84, contact 86, arm 52c, contact 87, wire 88, wire 76, thermostatic switch 53 to line 63, the lamp continuing lighted so long as the doors remain open. By moving switch 65 to contact 85, the circuit to field 44 is completed through line 62, field 44f, wire 72', switch 65 to contact 85, arm 89, wire 84, contact 86, arm 520 to contact 87, wire 88, wire 76, thermostatic switch 53 to line 63, the current in the armature 44a being reversed through line 62, wire 99, contact 90, arm 52b, contact 91, wire- 77, contact 93, arm 52a, contact 94, wire 81 to switch 65, thus reversing the motor and closing the doors, at which point, switch 52 is again reversed, the lamp circuit being broken at switch arm 520.
If instead of moving switch arm 65, switch 64 is reversed, the circuit would be completed through switch 65 to contact 97, wire 73, contact 96, arm 74 or 89, contact 95, wire 84. Therefore by operation of either switch 65 or 64, the doors are opened, the lamp 61 being lighted as soon as the doors are fully opened, and switch 52 reversed, thereby reversing the motor connections to either armature or field as desired and breaking the circuit, except to lamp 61. By reversing either switch 640i 65 the doors are-closed, and when fully closed, switch 52 is reversed to original position, the lamp circuit being, broken as also the motor circuit. This arrangement'provides for the lamp being lighted as soon as the doors are fully opened, and maintaining said lamp lighted until the doors areclosed.
Should any obstruction prevent the doors from opening or closing, slowing up. or stopping of the motor would cause an increased current to flow through the resistance in the thermostatic control;
switch, causing a heat expansible element 100 to cause a switch therein to open and break the circuit, maintaining a broken circuit until manu ally restored. p
The motor 44 by means of: pulley 43, belt 4 and pulley 41 integral with shaft '32 causes said shaft tosrevolve with worm 31 affixed thereto, said worm driving worm gear 27 whichis fixed to shaft-24 androtatable in bearings 25 and 26. Bevel pinion 21 is fixed to shaft 24 and meshes with bevel gears '15 and 18, thus revolving said bevel gears in opposite directions. Bevel gear 18 isfixed to shaft 13. Shaft 13 has the lever. 12 attached thereto at the lower end, and in the circuit described turns in a'counter clockwise direction, and by means-of arm 9 and. rod 6, with shoe 2 attached to door 58, pulls this door to closed positiomcoincidently therewith, bevel gear 15 with clockwise rotation, rotatable on; shaft 13, hub 14'being rotatable in bearing .16, and arm 11 being attached to said hub, closes door 57 by cooperation with arms 8 and rod 5,ish0e 1 being attached to door 57. r
As shaft 13 revolves in a counter clockwise di rection, cam 45 coacts with tine 98, lever 47 swinging on pivot 48 and swinging spring 50 across the pivotal center of the snap switch operating arm, spring 50 thereby reversing switch 52, breaking contact between points-93 and 94, 91 and 90, and 86 and 87, and making contact between .66 and 67, 68 and 69, and and 71.-
