v Improvements in Clock Dials, of which the 7 following is aspecification. Y
, structional purposes, .the students the; use of a clock but Will Be it known that I, a citizen of theUnited States, residing at Rhinelander, county of Oneida, and State 'ofIVisconsin, have invented new and useful Myinvention relates to improvements in clockjdials, said improvements beingsu'ch as to be useful for-instructional or edueational purposes. we v I 5 1 w a My invention has for its object the provisionof a clock-,with a dial which will facilitate the instruction of students in the use of a clock. v a 1 iv Another object of my invention lsto provide a clock didl which, when used-for inwill not only teach familiarizethem with the alphabet andthe numerical system. x
In the drawings;
Figure 1 is a front elevation of a clock provided with adial embodying a preferred form of my invention.
Figure 2 is av front of my invention.
, Figure 3 is illustrative ,of an embodiment;
of my inventionin a dial alone, means being provided whereby the handsmay be: operated manually without the association of a clock mechanismtherewith." v
Figure 4 isa detailaview illustratingjthe manner in which distinctive colorings are 1 used to identify each of the hands with one of the rows of characters.
Like parts are identified by the same reference characters thruout the several VIGWS."
The clock 1 with which my improved dial is associated may be of any suitable form. v
Preferably however, it is provided with minute and hour hands of two different colors, for example, the hour hand 2 may beblack and the minute hand 3 may be red.
These hands 2 and 3 are adapted to be moved by the clock mechanism within casing 1 over the surface of a dial 4 of novel form. A number of concentric circles shown at 5, 6 and 7 are inscribed uponthe dial of the clock adjacent to its periphery,
for the purpose of marking ofli' annular spaces adapted to receive numerals and other characters, as will be hereinafter described;

dial to a termination with the letter X at the intermediate pointbetween the numerals XII and I, as clearly appearsinthe draw to the minute hand 3.
The two rows 20 and 25 of alphabetical characters may be colored similarly it desired. Preferably however, I make the inner row 20 with black characters and make the characters of the outer row 25 red. In this way the characters of row 20. correspond in color to the hour hand 2, while the characters of row 25 correspond in color Another way of attaining the same result is to make the characters of both of the above rows of one color, but to provide different colors or backgrounds which will correspond to the colors of the two hands of the clocks. For example the clock hands might remain black and red and the alphabet characters might be printed in white on backgrounds respectively black and red.
. It so desired the dial 4 need not be connected to a clock mechanism but may be used independently, the various circles and rows of characters being inscribed upon a sheet of cardboard which will be provided with a pin 26 upon which will be pivoted the hands 2 and 3. The hands 2 and 3 may then be adjusted manually to any point which seems desirable for the purposes of instruction.
My device may be used as follows:--
The instructor, with a number of pupils before him, and with my improved clock dial within the view of the pupils, will set the hands to any desired point upon the dial and will then. call upon the pupils to state what time is represented by that position of the hands, and what letter of the alphabet each hand points'to; or without moving the hands at all he may take pieces of chalk corresponding in color to the color of the hands and write upon the blackboard a letter of each color. The pupils will then be called upon to state what time is represented by the colored alphabetical characters so drawn upon the blackboard.
In so doing they will consider the elockhand of a given color as pointing toward the letter of the same color which was written on the blackboard by the instructor. If it is preferred to conduct the class orally. it may be understood between the instructor and pupils that the first alphabetical character mentioned by child will very rapidly learn to tell time,
to recognize the use of the Arabic and" Roman numerals, and to know the letters of the alphabet presented on the dial in their natural sequence. My invention will,there fore, prove very valuable in the kindergarten, the home, and inschools for foreigners. I
lclaimc V l. The combinationwith a'cloek mechanism, of a dial operativelyassociated there with, hands of different colors adapted to be rotated by the mechanism around the dial, an annular row of figures designating hours upon the dial, and concentric rows of alphabetical characters, each characterized by a color identifying it with one of the hands. i v
2. A dial, a pair of hands pivotall-y'secured to the center thereof and adapted to be rotated about the pivotpoint,'an annular row of figures upon the dial, and a plurality of concentric rows oi other characters sig nificantly related to the figures,each of said last named rows being physically identified with one of the hands.
