TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES CHANDLER, of Syracuse, in the county of Onondaga, and State of New York, have invented a new and useful Improvement in Clocks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable-those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The nature cf my invention may be described as follows: I rst learn the distance the clock-weight falls with once winding. If it is three feet, I take a narrow strip of board three feet in length, and place it vertically by the side of tho clock-weight. I attach to the said weight an index that will slide over the face of the board as the weight runs down. At any given-hour, say at eight oclock, I mark on the hoard the position of the index, and at the end of one hour, or at nine oclock, I again mark the' position of the index; and now, having found the distance that the clock-weight falls in one hour, I take my dividersand space'out twenty-four hours on the face of the board, and also mark on the board the proper number of each'hour-point. I divide and subdivide each hour into fractions, similar to inches and fractions cfa carpenters measure or rule, and that gives a dial in a straight` line. I place a pulley above the clock-weight, which may be seen by the drawing in room A. I have a cord from the pulley to the bottom ot' the clock-weight when it is run down. For example, I wish to carry the time one hundred feet distant; Ihave a wire one hundred feet long" fastened to the cord at the pulley, and at the latter end ofthe wire I have cord and pulley No. 2, with a small weight, suicientto keep the wire straight Aand draw it back when the clock is wound up. I put an index on the small weight, and place a dial perpendicularly like that at the elock-weight, only vz'ee versa, as thclittle weight runs up when the clock- .weight runs down. That gives me the time in room I. In rooms E, F, II, and G, I place the dials horizontally,

parallel with the wire, with an index on the wire in each room. For rooms A, B, C, and D, it is more convenient to have the dials perpendicular, as will be seen by the drawing. The object in having a dial at the clockweight is to sce how to wind, as follows: If I wind the clock ata quarter past nine oclock, Iwind to that point, and no further, which causes each hand or index to return to the regular time ready for another twenty-four hours travel. For strikingr the h our, I have two bars crossed, forming four different levers, with a hole in thc centre for suspending the levers on a pivot; one of the bars reaches to the pins of' the striking-wheel. Lever No. I raises the hammer in the upper room A. I have a hole in the middle of the hammer-handle. Lever No. 2 raises the hammer in rooms E H. Lever No. 3 raises the hammer in room D. The pivot and hole are at the end of the hammer-handle. I add suilicient weight to thc striking-weight to raise thc'diiferent hammers. I also learn what the aggregate weight ofthe small weights is, and add that amount extra to thc main clock-weight.

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

The application of cords and wires to theclock and weight, as herein described, for the purpose of indicat ing the time and striking the hour at various points.
