Specification of Letters Patent.
Patented Aug. 17, 1920.
Application led June 20, `1919. Serial No. 305,451.
To all 'whom it may] concern Ie it known that I, CHESTER Il'. ANDER- soN, a citizen of the United States, and a resident of' Los Angeles, in the county of Los Angeles and State of California, have vinvented a new and Improved Clock, of which the following is a full, clear, and exact description.
This invention relates to clocks, and has for an object to provide an improved con-A struction wherein the time indicating means is arranged so that a number will indicate the hours and an oscillating pointer will indicate the minutes.
Another object of the invention is to provide a clock mechanism oscillating an arm or pointer and rotating a number dial, the arrangement being such that the mechanism may be connected to an ordinary minute hand shaft of an ordinary clock now in common use.
A still further object of the invention is to provide means which are capable of being connected to ordinary clock mechanisms now in common use, which will cause a minute hand or pointer to operate in proper time over a dial for indicating the minutes while moving numbers successively in front of an opening in the clock dial to indicate the hours.
In the accompanying drawing:
Figure 1 Ais a front view of a clock embodying the invention, the same illustrating the imrticular arrangement of dial.
Fig. 2 is a vertical sectional view through Fig. 3 on line 2 2.
1F ig. 3 is a rear view of the mechanism for moving the pointer and the hour dial shown in 1 and 2.
Fig. 4 is a horizontal sectional view through Fig. 3 on line 4 4.
Referring to the accompanying drawing by numerals, 1 indicates the shaft of a clock which carries ordinarily the minute hand. The remaining part of the clock is not shown in the drawing, as the particular construction of the clock forms no part of the present invention, whereas the present invention is merely connected t0 the shaft 1. This shaft, as shown in Figs. 2 and 3, extends through a suitable aperture in the rear of casing 2, which casing is comparatively thin, and which is provided with a face plate or dial 3, which is constructed as shown in Fig.
1. This face plate or dial is provided with an opening fl for showing the numbers 5 on the hour disk 6. In addition a bracket or fitting 7 is arranged in front of the dial and supported by suitable standards S extending into the casing 2, said iitting supportingfone end of the' shaft 9 to which the lever 21 is rigidly secured. A minute hand 10 swings back and forth between the zero mark 11 and the sixty mark 12. The hand or pointer 1() when swinging from zero to sixty moves at the regular rate of a minute hand of an ordinary clock, so that it will be one hour from the time the han d or pointer leaves the zero until it reaches the number sixty, but when moving back to zero it takes only a short time, as for instance the fraction of a second. This construction and arrangement permits any one to quickly see the time of day` both in hours and minutes.
he mechanism for producing the result just described is shown in elevation in Fig. 3, wherein it will be seen that the hour disk (i is loosely journaled on the shaft 1, but is held normally in a given position by spring 13 which is bent at 14. The bent portion 14 fits in between two of the teeth 15 of a toothed wheel 16 which is rigidly secured in any desired manner to the hour disk 6. The disk 6 is provided with a plurality of notches 17, there being twelve notches in order to indicate the different hours of the day. These notches are arranged on the periphery, in order to readily receive the hook end of arm 18, which arm is pivotally mounted at 19 on projection 20 of the operating lever 21. The operating lever 21 is rigidly secured to the shaft 9 and is being continually urged to swing toward the shaft 1 by spring 23 which is connected at one end to the lever 21 and at the other end to the stationary part of the casing 2. When the cam 24 slips off of the pin 25 carried by the lever 21 said lever will move under the action of spring 23 until it strikes the cam 24 approximately at the point 25 near shaft 1. This quie action under the impulse of spring 23 will cause the pointer or hand 10 to move back to zero on the graduations 26. At the same time the end hook of the arm 18 will engage in one of the teeth 17 and pull the hour disk 6 until it is moved sufficiently iar to expose another number through opening 4. When this occurs the toothed wheel 16 will be movedy against the action ot' spring 13 and' the bent portion 14 of the spring will snap between the next two teeth l5 for locking-the disk-1G in itsfne'w position. As the shaft l to which the cam 24 is rigidly secured con- X tinually rotates the minute hand 10 willV `-a dial plate having an arc-shaped graduaagain begin to move over its course toward the end l2.
In connection with the' arm 18 it will be noted that theV hook end thereof is preferably formed as a pin 22 which not only en# gages the notches 17, but also is engaged by a spring 27 so as to cause the pin to instantly'snap into the notch 17V when permitted to do so.
l/Vhat I claim isf l.
