J. F. JONES AUTOMATIC FLOOR INDICATOR FOR PASSENGER ELEVATOR S Filed Feb. 20,
Patented Mar. 23, 1926.
UNITED STATES JOHN F. JONES, OF CHICAGO, ILLINOIS.
AUTOMATIC FLOOR INDICATOR FOR PASSENGER ELEVATORS.
Application filed February 20, 1924.
To all whom it may concern:
Be it known that I, JOHN F. JONES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Floor Indicators for Passenger Elevators; and I do declare the foliowing to be a full, clear, and exact description o1 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention aims to provide a simple, yet an eitective device adapted to be carried by the car or cage of a passenger elevator, in full view of the passengers, so that by simply looking at the device, the floor position of the elevator can be seen, thus etlectively overcoming a great deal of con fusion and inconvenience which ordinarily results, particularly in the elevators of rather tall buildings.
1th the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.
Figure 1 is a vertical sectional View through a portion of an elevator shaft, and a number of its doors, showing the elevator car in elevation, equipped with the indicating means.
Figure 2 is a sectional view as indicated by line 2-2 of Fig. 1, diagrammatically illustrating the electrical means for illuminating the floor indicator.
Figure 3 is an enlarged vertical sectional view as indicated by line 33 of Fig. 1, showing the floor indicator in elevation.
Figures 4: and 5 are transverse sectional views as indicated by lines 4- 1 and 55 of Fig. 3.
Figure 6 is a longitudinal, substantially vertical section through the indicator, as indicated by line 6-6 of Fig. 4.
Figure 7 is a horizontal sectional view on line 7-7 of Fig. 6.
Figures 8 and 9 are elevations partly in section, showing the manner in which the elevator doors control circuit-closing switches for the illuminating light of the floor indicator.
In the drawnig above briefly described, I have illustrated a passenger elevator car C within a shaft S which is provided with the usual doors D at the several floors F.
Serial No. 6%,081.
Mounted within the cage or car C, at a point preferably over the door-thereof, I have shown a casing 1 having a view opening 2, and if desired, this casing may set atan angle as shown in Figs. 2 to 5, in order that the floor numbers which are successively displayed at the opening 2, may be more readily visible to persons standing near the door. In the ends of the casing l, I have shown rollers 3 and l around which a belt 5 is trained, said belt having floor numbers as indicated in Fig. 3, to be successively displayed at the view opening 2.
Any suitable provision may be made for driving the belt 5 in synchronism with the movement oi the car 0. In the present disclosure, arelatively l: rge bevel gear 6 is so cured upon the shaft of the roller 4 and meshes with a small bevel pinion 7, this pinion being secured to the inner end of a horizontal shaft 8 which passes to the exterior of the car C and is provided with a rather large wheel 9 which is by preference formed with a peripheral groove. A cable 10 is passed one or more times around the wheel 9, as indicated at 11, and the ends of this cable are adapted to be anchored at the ends of the shaft S as indicated at 10 in Fig. 1. Thus, as the car 0 travels upwardly and downwardly, the roller 4 will be driven to properly move the belt 5 in timed relation with the car travel, so as to properly present the floor numbers at the opening 2.
IVithin the casing 1, behind the belt 5 and the View opening 2, I have illustrated an electric light 12 for illuminating the number at the opening 2 whenever the door D at any floor is opened. For purposes of better representation, this light is shown in Fig. 2, below the casing 1 and this figure diagrammatically illustrates one system of wiring which may be used in connection with switches at the several floors, controlled by the doors D. In the construction shown, each switch includes a casing 13 mounted in the elevator shaft at the upper end of a door D, said casing containing a stationary contact 1a with which a movable switch member 15 co-acts, said switch member having a spring 16 for closing it, but being also provided with a control member 17 extending to the exterior oi the casing 13 in position to be struck by the door D, or one section of the latter, if it be of the vertically divided type. As long as the door D is closed, it holds the control member 17 in position to retain the switch 15 in its open position as shown in Figs. 2 and 8, but as soon as the door starts open, the spring 16 moves said switch member to closed position asillustrated in Fig. 9, thus automatically illuminatingthc light 12 and attracting the at- 'tention of the passengers to the number of vided for carrying out the objects of the invention, but I Wish it understood that the present disclosure is principally for illustrative purposes and that Within the scope of the invention as claimed, it may be embodied in numerous other forms.
I claim:
A floor indicator comprising a casing having a view opening and adapted to be carried by an elevator car, a belt in said casing having floor numbers adapted to be successively presented at said view opening, rollers in said casing mounting said belt, a shaft connected operatively with at least one of saidrollers, a Wheel on said shaft at the exterior of the casing, and a cable adapted to be passed around said Wheel, said cable being of a length to extend substantially throughout the length of an elevator shaft and the ends of said cable being adapted for anchorage at the ends of the shaft.
In testimony whereof I have hereunto afiixed my signature.
JOHN F. JONES.
