IMPROVEMENT IN WATCHES.
Specification forming part of Letters Patent No. 192,222, dated June 19, 1877; application tiled May 2, 1877.
To all whom yit 'may concern:
`Be it known that I, EDWARD G. BoYNn'r'r, of Jersey City, in lthe county ot' Hudson and State of New Jersey, have invented a new and useful Improvement in VatCheS; and I do hereby declare that the following is a full, clear, and exact description ot' the same, ret'- erence being had to the accompanying drawing, forming part of this specification.
It is well known that a \vateh-movement, to keep time with the most fperfeet accuracy, should be always kept in the same position, and that itl regulated in one position it will not go so accurately in another position.
The object of this inventionl is to provide for keeping the movement always in the same position, whether the watch be carried in the pocket or whether it be hung up when not so carried; and to this end the invention consists in applying the movement within the case ot' the watch upon ah central pivot, upon which it is free to rotate or oscillate, so that the heaviest part or center otl gravity of the movement will always i'all below the said pivot, when the watch is carried, suspended, or placed in an upright, or approximately upright, position, without regard to which part ot' the case is uppermost.
The invention is illustrated in the accompanying drawing, in which Figure 1 is a central section ot' as much ot' a watch as is necessary for the illustration. Fig. 2 is ariew of the inside ot the back of the case, showing the position ot' the central pivot. Fig. 3 isa back view of the movemcntdetached from the case.
In this example of my invention, the eentral pivot a, upon which the movement hangs vand swings when the watch is upright or on edge, and which is attached securely to the inner back B ofthe case, enters into a central bearing provided in the center arbor c, which carries the center pinion e and minute-handf of the watch. In order to provide for this bearing in the center arbor c, the rear portion of the said arbor is made somewhat larger than usual, and bored centrally from the rear end, the central bore constituting the bearings. A is the principal plate ot' the movement. C is the bridge, which receives the rear pivot ot' the center arbor c, and D is the dial.
By making the bearing for the central pivot a in the center arbor c, the necessity ot making the watch any thicker is obviatcd or reduced; otherwise the bearing for the central pivot might be provided without altering the 'working parts ofthe movement.
The central pivot a. might be attached rigidly to the movement, and turn in a bearing in the case. I, however, prel'er the construction shown.
It will be readily understood that when the movement is thus arranged on a central pivot, if the center ot' gravity of the movementis at any distance from the center arbor c, it must always fall below the central pivot ay when the watch is suspended or set up edgewisc, and that, therefore, the movement will then always occupy the same position without respect to which part ot the case is upward or downward.
What I claim as my invention is- A watch hav-ing its movement placed on a central pivot, on which it is i'rce to oscillate or rotate, substantially in the manner and for the purpose herein described.
