N0. 144,270. l Patented Nov. 4, 1873.
UNITED STATES PATENT OFFICE.
ARNOLD FRANKFELD, OF NEI/V YORK, N. Y.
IMPROVEMENT IN WATCHES.
l Specication forming part of Letters Patent No. 144,270, dated November 4, 1873; application filed April 2e, 1873.
To all ywhom t may concern:
Be it known that I, ARNOLD FRANKFELD, of the city and State of N ew York, have invented an Improvement in Watches, of which the following is a specification:
latches are usually made with the parts of the escapcment and balance either between the main plates ofthe watch or upon the same. In these positions diiculty arises in obtaining access to all the parts and carefully observing the movements in constructing` and. adjusting them; besides this, the movement is usually made by workmen of less skill than those employed upon the escapcment and balance. This renders it necessary to construct and apply the train or movement in the watch previously to the introduction of the balance and the escapement, or else they are liable to injury, and balances of one grade of workin ansip cannot be i11- serted in watchmovements in place of those of another grade.
My invention is made with reference to avoiding these difliculties by constructing the balance and escapcment upon a detachable plate, that can be placed in or removed from the watch 5 thereby the balance and escapcment can be more easily constructed and adj usted than heretofore, and can be removed from the other works of the Watch while they are being completed or fitted into the case, and the escapcment and balance can be applied in any works of corresponding size, thus allowing the escapements to be che nged from one watch to another, if the grade of workmanship is required to be different.
By this improvement the different parts of the watch can be in progress of construction at the same time in the hands of different workmen, and they are afterward brought to gether for joint action and regulation.
In the drawing, Figure l shows the plate and setting mechanism. Fig. 2 is the balance, escapcment, and its plate detached.
The principal watchplate ay and the hall? plate b are connected together by the columns c, and the plate a is of a sufficient thickness to be recessed for receiving the different parts, or may be made of two pieces. At one side thc plate a is made sufficiently thin to receive upon it the quarter-plate d, having at its back a disk, e, riveted or screwed securely to its place, and of a size to lit the hole that is made for it in the plate a. When these parts are put together, the plates fit closely and tightly, and are to be connected by screws; but the quarter-plate d and its disk c can be taken oif the plate e and receive the escapcment and balance. The balance f, anchor or other escapeinent 1', and escapcment-wheel l are of any usual or desired character, and g and h are the brackets for carrying the upper pivots.
It will now be seen that the quarter-plated can be removed from the plate a, and all `the parts of the balance and escapcment introduced and properly adjusted, and tted in the most accurate manner, and with opportunity to easily inspect the parts.
The length of arbors will not in any manner be lessened, because they all extend to the disk e, in which are the proper pivot-holes or jewels, and the thickness of the plate is such that the wheels, escapcment, &c., may be rev cessed. This results from the disk e being attached to the plate d, and hence being in the same plaire as the watch-plate, and allowing the arbors to be of the same length as usual.
I claim as my invention- The quarter-plate d and disk e, carrying the balance and parts of the escapcment, and re^ movable from the plate a, suliistantially as and for the purposes set forth.
