HOROLOGI CAL DIAL Filed June l5, 1927 IN V EN TOR.

HOROLOGICAL DIAL Application filed .Tune 13,

This invention relates to dials with reference to hoiological or time keeping devices and has as its object to provide a straight flat dial bearing divisions of hours and minutes on its respective sides, each being served by an appropriate hand, continuously driven by any type of clock or watch movement through endless carriers operated in vsynchronism thereby.

A further feature is in the provision of a unique type of dial easily read and with less liability of confusion than the ordinary circular dial or other type in which both hands radiate from a common center.

Another purpose is to arrange a dial having straight parallel rows of numerals disposed in spaced relation and to incorporate a circular dial midway therebetween for the second hand.

These advantageous objects are accomplished by the novel design, construction and arrangement of parts hereinafter described and shown in the accompanying drawing, which is a front elevational view of one form of an embodiment of the invention.

The frame or body casing of the time-piece is shown with extending ends 5 and 6, this frame being generally rectangular and may o be so mounted as to lie flat or stand erect.

Fixed in the face of the frame, intermediate the ends 5 and 6, is a flat dial 7 bearing a pair of spaced, parallel rows of numerals 8 and 9, reading from left to right, the former designating the hours, starting at 12 and ending at 12 and the latter designating the minutes, starting at 607 and ending at 60, each unit representing five minutes.

Intermediate the numeral rows 8 and 9,

midway the length thereof is a conventional small, circular dial 10 designating the seconds.

Mounted in the frame is a clock or watch movement, not shown, of the usual type, driving a spindle 11 on which is fixed a large gear 12 and a pinion 13.

The gear 12 meshes with a small gear 14 secured on a spindle 15 carrying a large sprocket wheel 16 and the pinion 13, through an intermediate gear 17, drives a gear 18 1927, Serial No. 198,336.

fixed on a spindle 19 carrying a sprocket wheel 20.

The teeth of the sprocket 16 project through the adjacent side of the frame to drive a flexible endless carrier 21 composed' of a plurality of spherical links connected to constitute a chain trained over idle pulleys 22 rotatably mounted on the frame side at the top and bottom thereof, the carrier carrying a plurality of uniformly spaced indicators 23 passing over the face of the dial .7 adjacent the minute row 9 and the sprocket 2() extends beyond the opposite frame side to move a carrier 24 similarly mounted on pulleys 25 and carrying like indicators 26 to designate the hours, it being understood that the clock mechanism actuates a conventional second handover the circular dial 10.

The frame supports guides 27 at each side, the same enclosing and supporting the carriers as shown.

It will be noted that each carrier actuatesA four indicators so that as one indicator leaves the dial at one end, the next one starts over the dial from the opposite end;

In use, the time is read from left to right, so that, if the indicators are positioned as shown, it is obviously, approximately twelve minutes past four.

It is to be noted that any desired clock mechanism. may be used to operate the indicators, since the invention merely resides in the specific fiat dial shown having a row of numerals representing the hour and another row designating the minutes, and with or without the seconds dial.

It will be understood that the dial 10 may bearranged horizontally in place of vertically as shown or at any preferred angle. the hands moving in the manner above described.

Although I have described my improvements with considerable detail and with respect to certain particular forms of my invention, I do not desire to be limited to such details since many changes and modifications may well be made without departing from the spirit and scope of my invention in its broadest aspect.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In combination with a clock casing containing an operative selfcontained movement having two driving Wheels spaced apart in the saine plane and actuated at a speed ratio of one to twelve, pairs of pulleys freely rotatable at the ends of said casing, series of spheres flexibly engaged together to constitute endless chains trained over said pulleys, said chains being operatively engaged by the driving wheels on respective sides of said casing, pointers fixed at intervals to said spheres, and an index dial on theface 15 of said casing over which said pointers move longitudinally andL continuously in one direction.

In testimony whereof I aHX my signature.

JOSEPH KONIGSBERG. f
