Abstract
Abstract The invention provides a time indicating device which contains an endless indicating belt carrying indicating means thereon that define three or more equally spaced segments of said belt, the belt passing beneath a face plate with an elongated opening therein mounted adjacent the belt so that from time to time said indicating means carried by said belt are visible through said opening, the length of said opening substantially corresponding to the length of one of said segments so that when said belt is moved past said opening there will be a moment when one of said segments will appear over the entire length of said opening. The device is especially useful in clocks where a plurality of belts are employed which are driven at different speeds to indicate seconds, minutes, hours or, if desired, additional belts can be used to indicate days, weeks, months or other time periods.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
A time indicating device comprising an endless indicating belt which carries non-digital indicating means thereon that define three or more equally spaced segments of said belt, means comprising a face plate with an elongated opening therein mounted adjacent said belt with said opening in superposed relationship to said non-digital indicating means so that from time to time said indicating means carried by said belt beneath said opening are visible through said opening as said belt is moved past said opening, said face plate carrying time period indicia on the top thereof adjacent said opening, the length of said opening substantially corresponding to the length of one of said segments and said non-digital indicating means being spaced apart a distance corresponding to the length of said opening so that when said belt is moved past said opening there will be a moment when one of said segments will appear over the entire length of said opening with two consecutive said non-digital indicating means appearing, one at each end of said opening, and means for moving said belt containing said non-digital indicating means past said opening.
Claim 2
Dependent Claim
184 words
A time indicating device comprising an endless indicating belt which carries non-digital indicating means thereon that define three or more equally spaced segments of said belt, means comprising a face plate with an elongated opening therein mounted adjacent said belt with said opening in superposed relationship to said non-digital indicating means so that from time to time said indicating means carried by said belt beneath said opening are visible through said opening as said belt is moved past said opening, said face plate carrying time period indicia on the top thereof adjacent said opening, the length of said opening substantially corresponding to the length of one of said segments and said non-digital indicating means being spaced apart a distance corresponding to the length of said opening so that when said belt is moved past said opening there will be a moment when one of said segments will appear over the entire length of said opening with two consecutive said non-digital indicating means appearing, one at each end of said opening, and means for moving said belt containing said non-digital indicating means past said opening.
Claim 3
Dependent Claim
18 words
A device as claimed in claim 1 in which said belt contains only three said non-digital indicating means.
Claim 4
Dependent Claim
22 words
A device as claimed in claim 1 in which said non-digital indicating means consist of three dots equally spaced around said belt.
Claim 5
Dependent Claim
49 words
A device as claimed in claim 1 comprising a plurality of said endless indicating belts, a corresponding number of elongated openings in said face plate through which the respective non-digital indicating means are visible and means for driving the respective belts at predetermined speeds with respect to one another.
Claim 6
Dependent Claim
88 words
A device as claimed in claim 4 in which there are three endless indicating belts disposed adjacent three elongated openings, said openings containing time period indicia adjacent thereto on said face plate calibrated in seconds, minutes and hours, respectively, and said driving means being operative to move one of said segments of each said belt from one end to the other of its respective opening at the following speeds: the seconds belt in 60 seconds, the minutes belt in 60 minutes and the hours belt in 12 hours.
Claim 7
Dependent Claim
37 words
A device as claimed in claim 1 in which said belt is driven by means operative through a slip clutch to permit moving said belt by manual means to a predetermined setting without affecting the driving mechanism.
