Description

A. F. BOWERS. 'DOOR OPERATINGv MECHANISM. APPLICATION FILED- OCT. 4, 1916.
1,341,775: Patented June 1, 1920.
ARTHUR nnownns, or MILWAUKEE,.VJISCONSIN. I
nooiarornnnrrrre MEonANIs-M.
To all'io'hom it may OOILCGWL-l Be it known that I, ARTHUR F. Bownns, a citizen ofthe United States, and resident of Milwaukee, in the county of Milwaukee and State of l/Visconsin, have invented new and useful Improvements in Door- Operating Mechanism, of which. the following; is a description, reference being had to the accom panying drawings, which are a part of this specification.
- The invention relates to door operating means more particularly for use in connection with garage doors whereby the door or doors may be opened and closed through the agency of an electric motor operated from a remote control.
The invention is further designed to pro vide a motor operated door opening means including a gearing connection'between the motor and the door so that the door is locked against movement until the motor is operated.
The invention further consists in the several features hereinafter set forthand more particularly defined by the claim at the conclusion hereof.
In the drawings:
Figure 1 is an elevation view of the device embodying the invention, said device being located inside the building;
Fig. 2 is a section taken on the line 22 of Fig. 1;
Fig. 3 is a section taken on the line 3-3 of Fig. 1; V
Fig. 4 is a diagrammaticvview of electric wiring for the electrical control.
In general, the device comprises an electric motor M, a gearing connection between said motor and the door, a remote control for the motor, and means for opening the motor circuit when the door reaches either its open or closed position.
In the construction shown in Figs. 1, 2 and 3 the motor M is mounted on a base plate 7 secured to thewall 8 of the building adjacent the swinging door 9. The gearing connection between the motor M and the door 9 comprises a gear 10 mounted on the motor shaft 11 and meshing with an idler gear 12 which in turn meshes with an annular rack 13 secured to the inner side of the door 9. The'gear 12 is mounted on a shaft 14 journaled in bearing brackets 15 mounted on the plate 7 The rack 13 is pivotally secured at one end to a bracket 18 mounted Specification of Letters-Patent. pm fig J 1, 9,
Application filed October 4, 1916. Serial No. 123,626.
on thedoor 9 by a pin 17. The rack is held inmeslr with the gear 12 and guided in its movement by a grooved guide wheel 18 mounted on a shaft 1 9 journaled in bearing brackets 20 mounted on a base plate 21'. Vfith this construction when the motor shaft'is rotated the door will be swung to open or closed position depending upon the direction of rotation' of themotor shaft:
through the Y gearing connection consisting of the gears 10 and 12 and rack 13.
. The motor control means comprises a switch S located at a distance from the door and having contacts 29, 30, 31, 32, 33 and 34 and electrical connections leading from these contacts. The current from the line 35 passes through the field F and a conductor 36 connects said field with switch contact 29. A conductor 37 connects switch contact 29 with switch contact 34. A conductor 38 connects switch contact 33 with the line conductor 39 and a conductor 40 connects the switch contact 31 with conductor 39. A conductor 41 connects the armature A of the motor with switch contact 32 and a conductor 42 connects armature A with switch contact 30.
The means for opening the motor circuit when the door reaches either its open or closed position comprises normally closed circuit closures 43 and 44 which are opened when the door presses against them.
The operation of the motor control is as follows: When it is desired to open the door the switch S is moved to its upper position at which time the current flows from line conductor 35 through field F, conductor 36, contact 29, right arm switch S, contact 30, conductor 42, armature A, conductor 41, contact 32, left arm switch S, contact 31, conductor 40, the closure 43 being normally closed, and thence through line conductor 39 thus operating the motor which swings or slides the door to open position at which time circuit closure 43 is opened by the door and circuit closure 44 automatically closes. When it is desired to close the door, the switch S is moved to its lower position at which time the current flows from line con- I ductor 35 through field F, conductor 36, contact 29, conductor 37, contact 34, switch S, conductor 32, conductor 41, armature A, conductor 42, contact30, switch S, conductor 33, conductor 39, the closure 44 being normally closed, to the line conductor 39 thus motor which swings or slides the door to closed position at which time circuit closure 44 is opened by the door and circuit closure 43 automatically closes. When the switch is in raised position no current will flow.
The invention thus exemplifies a simple and efficient-motor-operated door operating means which may be operated from a remote control.
What I claim as my invention is:
The combination with a wall structure having an opening therein, of a door hingedly connected thereto for closing the opening, a base plate secured to the wall structure adjacent the door opening, a motor mounted on said base plate, two pairs of spaced apart bearing members mounted on said base plate, a pinion gear fixed to the end of the drive shaft of said motor, an idler gear journaled between one pair of said bearing members and in mesh with said pinion gear, a grooved wheel journaled between the other pair of said bearing members and having its periphery spaced a short distance from that of the idler gear, a curved rack member passed between the idler gear and the grooved wheel and having its inner tooth surface in mesh with the idler gear and its rear plain surface guided in the groove of said grooved wheel, means pivotally securing the inner end of said rack to the door, an electrical circuit for operating the motor in either direction to open and close the door, and means in said circuit and operable when the door reaches either of its limits of movement whereby to break the circuit and stop the motor. I
In testimony whereof I aflix my signature.
