@anni @ffm JULIUS ELSON, OF BOSTON, MASSACHUSETTS.
Letters Patent No. 113,281, dated April 4, 1871.
IMPROVEMENT IN WATCH-REGULATORS.
The Schedule referred to in thele Letters Patent and making part of the lame.
I, JULTUS ELSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Watch-Regulators, of which the following is a speci'cation.
Figure l is a plan view of my invention, and
Figure 2, a side elevation of the same.
The object of this invention is to produce a device for effecting the most minute adjustment of a watchregulator; and
It consists mainly of an ordinary regulator, provided wth a curved and slightly ilexible lever, bent downward atone end over a raised or depressed segmental bearing-edge ou the balance-bridge, (or any other segment of an arc which runs concentric with the motion of the regulator said bent end having a .screw passing'through the-same and bearing against said segmehtal' edge, as "will hereinafter more fully appear.
In thedrawing- A represents the regulator, which is of the usual form, and secured in the usual manner to the balancebridge B, which latter is provided with the depressed and grooved segmental edge O.
D represents a'eurved lever, which forms a part of the regulator A, and is bent vdownward at its outer end over the edge O, as shown in fig. 2.
The bent end of lever D is provided with a screw E, which passes through the same and bears against theI edge C, engaging with the groove thereof, as shown in fig. 2.
Operation.
The lever D may be moved in the usual manner for ordinary regulation, but when especial minuteness is required it is effected by the screw E, which, when turned in such manner as to cause it to bear against the edge O, will exert a tension on the lever D, drawing the end thereof outward, thereby imparting a slight motion to the regulator Ain the direction of the arrow, thus effecting the desired adjustment,
whichmay be indicated by a suitable pointer or index if desired.
This device is particularly applicable iu correcting in watches the'slight errors 'produced from an over or under-compensated balance, the regulator, as shown in iig. 1, acting to adjust an over-compensated balance, while the reversal of the curve of the lever D will, in a watch of similar construction, adjust an Aunder-compensated balance.
JULIUS ELSON.
