IMPROVEMENT IN WATGH-REGULATIN G ADJUSTMENT.
. fiilze ctfhul remh m in flgtse wiem ncnt ma mailing ;mi ni tt: sume.
Be it known that I, Dr. FRANK G. JOHNSON, of Port Richmond, in the county ofl Richmond, and State of New York, have invented a new and useful Improvement in Regulatng Watches; and I do hereby declare that the following is a full, clear, and exact description thoreof, 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.
This invention relates to an improvement in Watches, rvhereby the regulating-hand of the watch is so operated that it may be adjusted with the greatest nicety;
And the invention consists in fixing a fine-threaded screw in the watch with a movable grooved nut thereon, which nut, as it is turned on the screw, shall move' the regulating-hand, as will be hereinafter more fully described. I
Figura-1 is a partial top or plan view of a watch-movement on an enlarged scale, showing the balancewheel, hair-spring, and the regulating-hand connected with my regulating-screw and nut.
Figura 2 is a Vertical section of the same through the line x a'.
Similar letters of reference indicate corresponding parts.
The difiiculty of turning the regulating-hand of a watch, without moving 'it too much or too little, has probably been experienced by every one who has ever made the attempt.
To render the operation-of turning the hand and properly regulating the time-piece perfectly easy and sure, is the object I have in view in this invention. t
For'this purpose, I 'fix a fine-threaded screw, a, in the movement of the watch, so secured that it shall he stationary, and on the screw I place a grooved nut, a, which, by turning or revolving, can be moved back and forth or in either direction on the screw.
d is the regulating-hand.
The outer end of this hand 'may be flattened, as seen at e in fig. 2, so as to fit the groove in the nut, and be hold and moved thereby when the nut is turned.
The regulatinghand being placed in this position instead of on the plate, (as is usual,) the running ofthe watch may hesupposed to approximate to cori'ectness, the same as it would nsual position on the plate.
In the latter position, much or too little, while with my adjusting-nut and screw the slightest and most delicate movemcnt in either direction may bc given to the hand. i
The periphery of the nut C is corrugated or serrated, for convenience in moving or turning it, while the end of the'hand is made to fit the groove, so that there will not be any slack to take up. A
Instead of the flattened end, as seen at e, there may be a round pin inthe end of the hand, so that When the hand stands at an angle with the groove there would be no possibility of its binding. V
g is the hair-spring of the watch.
h is the balance-wheel.
I clziim as new, and desire to secure by Letters Patent The fixed screvf-shaft a, upon which the grooved nut c carryng the end of the regulating-hand d is rotated, all arranged and Operating as described, for the purpose specified.`
if the hand were placed in its FRANK G. JOHNSON. Witnesses WM. F. McNAMARA, ALEX. F. RoBnnTs.
it is next to impossible to move the hand at all either way without moving it too
