JEWEL-SUPPORT FOR BALANGESTFFS @F WATCHES.

SPECIFICATION forming part of Letters Patent No. 448,896, dated March 24, 1891.

Application tiled February 13, 1890. Serial No. 340,268. (No model.)

TorctZZ whe/nf it nm/y concern:

Be it known that l, J ULEs YILLON, of Liina,

in the Republic et Peru, have invented 4certain new and useful linprovenientsin lllatehes, of which the following is a specification. This invention has for its object to prevent injury to the pivot of a watch-balance by 'shocks or jars to which the watch-movement inay be subjected when accidentally dropped or otherwise given a violent blow; and it oonsists in the improvements hereinafter described and claimed, whereby all the jewels supporting the pivots et the stai't are enabled to nieve endwise of the statt', and the holejewels are enabled te nieve independently at right angles to or crosswisc of the direction et' the length et the stati'.

ln the accompanying drawings, torniing a part of this specification, Figure l represents a plan view et a portion et thcbalanee-bridge et a watch and the compensatien-balance arranged in its usual relation to said bridge. Fig. 2 represents ascetion online 2 2 et Fig-.1.

The saine letters et reference indicate the saine parts in both el' the hgures.

ln the drawings, a represents the conipensation-balance et a watch, the saine being of the usual er any suitable construction.

b represents the statt which supports the balance and has its ends reduced and formed as pivots in the usual way.

c c and c7 c represent the jewels which support the pivots oit the statt, the jewels c being socketed to receive the pivots, while the jewels c are formed to bear on the ends of the pivots. Said jewels are yieldingly held in place or supported by the springs d d. The spring d, which supports the jewels c c at one end of the statt, is attached by a screw c er other suitable ineans to the plate f, and the spring tl, supporting the jewels c c at the other end of the stall", is attached by a screw e te the balance-bridge g. The end or cap jewels c andthe socket-ed or hole jewels c are not rigidly connected, but are separable freni each other, although normally held in contact with each other, as shown in Fig. f2, by the springs d d, the cap-jewels c being atlixed to settings 7L 7L, which are rigidly attached to said springs, while the holcjewels c are atlixed to independently-niovable settings t' e", which are normally held by the pressure et the springs d d in circular recesses jj', toi-mcd, respectively, in a cylindrical bex lo, attached to the plate f, and in a circular flange 7u on the balance-bridge g. The settings i' t" are disks having beveled peripheries, which rest on th o angular shoulders or seats constituting the outer ends ot the reeessesjj. The beveled torni of the peripheries et' the settings i e" and the absence of positive connection between the said settings and the springs d d and cap-jewels c c enable the settings yL' 1l and their jewels c c to noove cdgcwise or laterally to a sufficient extent to prevent injury to the pivots when a shock or jar is experienced, which exerts a strain on said pivots in a direction at right angles te their length. It will be seen that in case the watch is dropped and strikes on the periphery of the case-center the beveled settings 'i t, yieldingly supported, as described, will yield cdgewise or laterally to a su iiicient extent te prevent injury to the pivots, said beveled settings slipping` on their seats and displacing the springs d d to the slight extent required to permit thc edgewise yielding ol the settings. lf the watch in falling strikes on one et the sidesot the case, one of the springs and beth jewels e c supported thereby yield in the direction of the length ot the statt' h, beth jewels yielding together. Provision is therefore made for the prevention of injury to the pivots by strains exerted thereon, either crosswise or lengthwise of the statt b.

l ain aware that it is not new to support the jewels of a balance-statt by springs, so that said jewels inay yield in various directions, and l do not claim, broadly, the combination, with a balance-statt, et jewels yieldinglysupported. l ani the first, however, so far as l ani aware, to provide the hole-jewels with settings having beveled pcriphcries which are yieldinglysupported on annularseats formed on the supporting portions or traine of the watch-movement.

rin advantage of niy improved construction is that the jewels normally have a rigid support and do not yield cxceptingto unusual. er excessive shocks, such as would be sufficient to injure the pivots, the settings f i, held against their seats by the springs, being uninlluenced by lighter jars, which are not sufiieient to cause injury to the pivots. ln all in,-

IOO

stances of the use of yieldiu g jewels of whichl am aware the jewels havebeen supported entirely by the springs and have no lateral bearing on seats on the supporting-frame ot' the movement, so that there is an objectionable absence of a sufiiciently-positive support for the jewels under normal conditions. This objection is overcome by my improvement. I prefer to guide the springs by means of the slots m mfformed, respectively, in the box 7o on the platefand in the flange con the balance-bridge g, the walls of said slots being in close proximity to the edges of the springs'.

1. In a Watch-movement, the combination, with the compensation-balance and its st-a, of the socketed jewels receiving the pivots of the stai, the settings containing said jewels and provided with beveled peripheries, the supports h aving circular recesses which present annular seats on which said beveled peripheries bear, and springs arranged to hold the settings on their seats with a yielding pressure, as set forth.

2. In a watch-movement, the combination., with the compensation-balance and its staff, ofyielding cap-jewels movable endwise of the staff, the hole-jewels contained in settings, which are independently movable crosswise to the movement of the cap-jewels, springs yieldinglyvsupporting said jewels, said sp rings being positively attached to the cap-jewels and bearing on the settings of the hole-jewels without positive connection therewith. whereby the hole-jewels are adapted to yield or 35 move independently, and the supports havin g circular recesses presenting annular seats on which the beveled peripheries of the hole-jewels are yieldingly held by the springs, as set forth.

3. In a watch-movement, the combination, with the compensation-balance and its staff, of the cap-jewels. movable endwise ot' the statt, the springs holding said cap-jewels in their free ends, the hole-jewels socketed to re- 45 ceive the pivots of the statt, the beveled settings holding the hole-jewels and movable edgewise therewith', and the supports having the recesses jj constituting seats which support the beveled peripheries of said settings, 5o the said springs bearing loosely at their free ends on the settings of the hole-jewels and holdingthe sameyieldinglyagainsttheirseats, as set forth. j

In testimony whereof IY have signed my 55 name tothis specification, in the presence of two subscribing Witnesses, this 19th day of November, A. D. 1889.
