Description
IMPROVEMENT IN REGULATING DEVICE FOR WATCHES.

'lO ALL WIIOM Il MAY CUNUEBN:
Be it known that I, ANDREW WARREN, ot' Waltham, in the county of Middlesex, and Stat-e of Massachusetts, have invented certain new and useful improvements in Means for Regulating Watches; and I do hereby decl-.1re that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suflicient to enable those skilled in the art to practise it,
It is well known that difliculty is experienced in moving the indicating lever of the regulating apparatus in a watch with any degree of certainty, to any fixed extent, including large as well as minute distances, and it is the object of my invention to afford a'simple and effective means for moving such indica-ting levers any given distance with ease and exact-ness, whether the distance be minute or considerable.
'l'his invention consists in the combination, with the indicating lever, of the ordinary regulator ot' a watch which acts upon-its hair-spring, of a disk-wheel, having a spiral groove cut in its upper plane face, through the means of a projection from the lever into the groove. Also in constructing a lever so combined with two or more projections, as that when, by rotation of the wheel having the spiral groove, one ofthe pins works out of said groove towards and past the centre of the wheel, consequent upon the movement of the lever, one or more pins or projections shall' have entered the groove from the outside, so that continued rotation of the wheel in the saine direction shall continue to move the indicating lever. In the drawings- Figure l shows in plan an illustra-tion of an embodiment of my invention` and Figure 2 is a cross-section taken on the line a: a, seen in fig. l.
s the regulator lever varies in its form, and in the detail of its connection withthe hair-spring in different watches, and as said matters are not of the essence of my invention, I will merely state that the lever is pivoted on the plate n, the short arm of the lever being the one which acts on the hair-spring, the long arm c being the indicator. In the plate a a countersinkor depression is made for the reception of the disk cZ, which is there pivoted to the plate, this disk hating formed on its upper surface a projecting spiral or scroll, between the coils of whieh'pins or projections enter, these pins being fixedin the long arms c of the lever, or in an ear,f, protruding therefrom. The periphery o f this disk-wheel [Z is serrated, so that with any suitable pointed instrument it can be rotated in either direction, when the scroll or spiral operating on the pins in the arm c of the regulator lever slowly and uniformly moves said lever in one or the other direction, according to the direction in which the wheel LZ is rotated. By means of the combination of devices shown, it will be obvious that very minute adjustments of the indicating point of the regulating lever can be madeby rotating the wheel d, as the ratio of the movement of the periphery of the wheel to the movement of the indicating end of the regulating lever is quite large. It will also be obvious that there is little chance for accidental movement ofthe regulating lever, as it is held in position by the engagement of its pins with the scroll or spiral on the wheel CZ, and the latter, being sunken in the plate n, is not liable to be accidentally rotated. When more than one pin in the regulator lever gears into the scroll-wheel, the construction inust be such that when the pin nearest the centre of the scroll-wheel, after having been worked out of gear with the scroll or spiral on one inner side thereof, abuts against the other inner side of the spiral, then the outer pin in the lever or its car j' must have been worked ont of gear with the opposite side of the spiral, otherwise rotation of the wheel Il would result in the breakage of some ofthe parts in the combination. A notch cut in the plate, as at y, permits ready access with any suitable pointed implement tothe serrated edge of wheel (.7, and a groove in the plate a, as seen at z, permits passage ofthe pins in the lever and its earf. By the employment of two or more pins, as described, it will bc evident that I can obtainfrom a given spiral a range of motion for the indicating lever greater than I could obtain with the sam-e spiral and but one pin.
I claim, in combination with the indicating regulating lever, a wheel having a spiral formation, and arranged to both hold and move said lever, substantially as described.
Also, in the said combina-tion, I claim the employment of two or more pins in the lever and gearing into the spiral, when the relation between the spiral and the pins is substantially that specified.
i ANDREW WARREN.
