UNITED fiTATES PATENT OFFICE.
ROBERT V. LONGTINE, OF LOS ANGELES, CALIFORNIA.
CLOCK-DIAL.
To all whom it may concern:
Be it known that I, ROBERT V. LONGTINE, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented new and useful Improvements in Clock-Dials, of which the following is a specification.
The object of my invention is to provide a clock dial which enables the time of day being read with the use of only one clock hand thus obviating the mechanism necessary for operating the usual extra hand and also obviating the necessity of observing two hands in order to read the time. I accomplish this object by means of the device described herein and illustrated in the accompanying drawings of which 2- Figure l.- is a face view of my improved dial. Fig. 2. is an enlarged view of a portion of the divisions on the dial.
Referring to the drawings 5 designates a dial of suitable material on which are printed or otherwise placed hour numbers 6 which are spaced around the dial in the usual manner. Outside of the hour numbers the dial is divided into minute designations 7 and five minute designations 8. The five minute marks are each provided with a number designation 9 which advance from five to twenty-five from hour marks 10 on each side. The thirty minute marks midway between the hour marks are distinguished by numbered designations 11 larger than the designations of the five minute marks. Immediately inside these designations and adjacent the hour numbers the words after and before are printed between each pair of hour marks, the after mark being adjacent the earlier of the two hour marks and the before mark being adjacent the later of the two hour marks.
In the reading of my clock dial the hour is first ascertained at a glance by the proximity of hand 12 to one or the other of the hour marks. The information as to whether the time is after or before the hour is gained by noting whether the hand is over the after mark or the before mark. The number of minutes after or before the hour is then ascertained by the coincidence of the hand with Specification of Letters Patent.
Application filed August 26, 1907.
Patented Jan. 5, 1909.
erial No. 390,087.
the five minute designations when accuracy to five minutes is all that is desired.
All the above information may be ascertained at a glance as the only parts which need to be particularly looked at are the minute designations or marks, the other information being capable of assimilation while the position of the hand over the minute marks is being ascertained.
From the foregoing description and by reference to the drawings it will be manifest that the time of day may be ascertained in the notation generally'used by reference to a single hand of the clock, this single hand corresponding to the usual hour hand of a clock. It will further be noted that I have obviated the necessity of the mechanism attendant a minute hand as the time of day may be ascertained from the single hand of my device more quickly than from a clock with two hands and with equal accuracy.
Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A clock dial, comprising a disk having twelve hour divisions thereon, defined by hour marks, each of said hour divisions being internally divided into minute divisions, minute divisions between any two adjacent hour marks being numbered rogressively from the said hour marks towards the middle of the hour division defined by said hour marks.
2. A clock dial, comprising a disk having twelve hour divisions thereon, defined by hour marks, each of said hour divisions being internally divided into minute divisions, minute divisions between any two adjacent hour marks being numbered rogressively from the said hour marks towarc s the middle of the hour division defined by said hour marks, and said disk having printed thereon adjacent the minute divisions the word before on one side of each hour mark and the word after on the other side thereof.
8. A clock dial, comprising a disk having l twelve hour divisions thereon defined by hour marks, each of said hour divisions being internally divided into twelve 5-minute divisions, and each of said 5-minute divisions one or the other of the minute marks, or with i being subdivided into five divisions, the first,
third, sixth, and ninth 5-minute divisions be- In Witness that I claim the foregoing 1 ing provided With other indicia to show the have hereunto subscribed my name this 17 half and quarter hours, and the Words "beday of August, 1907.
fore and after being printed upon said ROBERT V. LONGTINE. 5 disk adjacent said minute divisions and on Witnesses:
opposite sides respectively of each of said EDMUND A. STRAUsE,
hour marks. OLLIE PALMER.
