CHARLES KING, OF NEW YORK, N. Y.
Letters Patent No. 78,972, dated June 16, 1868.
IMPROVEMENT IN TIME-PIEGES.
dip firlphule referrer: in in time fishers new tut making part at tip smut.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, CHARLES KING, of New-York, 7 Delaney street, county and State of New York, have invented a new and useful Improvement in Time-Pieces; 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 drawing, forming part of this specification, in which drawing- Figure 1 represents a face view of this invention.
Figure 2 is a sectional side elevation of the same.
Figure 3 is a rear view thereof.
Similar letters indicate corresponding parts.
This ihvention relates to a. time-piece, in which the movement is balanced by one of the hands; both the movement and the hand being made to revolve round a pivot by the action of a balance-weight, which revolves round the central shaft of the movement, in such a manner that, by the action of a very small movement, a hand of any desirable size can be made to revolve, and a time-piece is obtained which shows the time at a considerable distance.
A represents the movement of an ordinary watch. From the case of this movement extends a rod, B, to the end of which is secured thc'index C. The rod B is perforated to admit the pivot a, and the weight of the index Ois adjusted in such a manner that the same overbalances the movement, when the pivot a is made to support the rod B, said rod being free to revolve on the pivot.
On the central axis of the watch-movement, I have secured a radius-arm, b, to the outer end of which is secured a balance-weight, a, in such a manner that said weight turns either with the central shaft itself, or with the hollow shaft that usually carries the hour-hand of the watch. This balance-weight is so adjusted that the same, when its radius-arm stands at right angles to the rod B, together with the weight of the movement, exactly balances the index C; but, if the balance-weight is turned towards the pivot a of the rod 13, the index ovcrbalanccs the movement and turns down, and, if the balance-weight turns away from the pivot (I, the movement ovcrhalances the index, and the latter turns up.
By these means, the index is carried round over the dial-plate, and the time is indicated.
If the balance-weight is attached to the arbor which usually carries the minute-hand, the index C revolves once in an hour, and it indicates the minutes precisely likethc minute-hand of a watch or clock; but if the balance-weight is attached to the arbor which usually carries the hour-hand, the index G revolves once in twelve hours, and it takes the place of the hour-hand. i
It will be readily undersood that, by this arrangement, an ordinary watch-movement is capable of moving a hand or index of great length, and a time-piece is obtained which takes but little room, and which shows the time at a great distance. 7
It is ohvious'that, by combining two movements, each with its separate index, a time-piece can be obtained which shows the hours and minutes; but if onlyyone movement is used, and the index 0 is made to show the hours, the ordinary minute-hand of thcmovcment shows the minutes, or, if the index C is made to show the minutes, the ordinary hour-hand of the movement shows the hours. i
What I claim as new, and desire to secure by Letters Patent, is-
The balance-weight 0, attached either to the arbor of the minute-hand or to that of the hour-hand 'of a watch-movcmcnt A, and operating in combination with said movement, and with the index C, substantially in the manner and for the purpose set forth. i
