. SPECIFICATION forming part of Letters Patent No. 527,772, dated October 23, 1894.
Application tiled January 25, 1892. Serial No. 419,251- (No model.)
To all whom t may concern/.- v
, Be it known that I, DUANE H. CHUEcH,-of Newton, in the county of Middlesex and State of Massachusetts, 'haveinvented certain ,new and useful Improvements in l/Vatches, of which the following is a specification.
This invention relates chiefly to pendant windingand setting watches, orthose in which the main-spring is wound and the hands set by aWinding-bar extending through the pendant of the watch-case, and rotated by a crown attached to said bar at the outer end of the pendant.
The invention has for its object to enable the projection of the outer'surfaces of the front and back caps ofa watch movement of this class to be reduced to the minimum without necessarily reducing the thickness of the case center, for the sake of compactness.
The invention consists in a watch movement, having in its pillar-plate a dial-receiving recess of less diameter than the diameter' of the pillar plate below the case shoulder thereon, said shoulder being above the bottom of the recess said recess requiring the use of a dial of proportionately less diameter thanheretofore, and enabling the margin of the pillar-plate to surround the dial as a wall of metal of sufficient thickness to support the case shoulder, sothat said shoulder can be made as close to the outer surface of the pillar-plate as may be desired, the thickness of such wall enabling the case shoulder to be formed on it above the bottom of the dial-receiving recess. By this construction, I am enabled to insert the movement more deeply into the case center, and with less projection of the dial side of the movement from the case center than heretofore, so that the bezel and (in a hunting case) the front cap can be made shallower or with less projection from the case center than heretofore, this reduction in the projection of the bezel and front cap permitting a corresponding reduction in the projection of the back, which is always made fuller or deeper than is required by the construction of the movement, for the sake of symmetry or uniformity of projection at both sides of the case. Hence I am enabled by my improvement to case the movement more closely than heretofore without reducing the width of the case center, the
part of this specication: Figure l represents a side view of a watch movement provided with my improvement. Fig. 2 represents an edge view of the same, partly in section. Fig. 3 represents an edge view of the movement in its case, the latter being shown in section.
The same letters of reference indicate. the same parts in all the gures.
In the drawings: a represents the pillarplate, b the top-plate and c the dial of a watch movement.
a represents the shoulder on the periphery of the pillar-plate, which bears on the seat formed for it on the case center, and is known as the case shoulder.
In carrying out my invention, I form a circular dialreceiving recess in the pillar-plate, said recess being of less diameter than the diameter of the pillar-plate below the case shoulder, so that the marginal portion of the pillar-plate is left intact, said portion constituting a Wall surrounding the dial and of sufficient thickness to support the case shoulder a', which shoulder is formed on said marginal portion or wall. Heretofore, the pillarplate of a watch movementhas not been provided with a dial-receiving recess of less diameter than the diameter of the pillar-platebelow the case shoulder. Hence the said shoulder has always been located considerably below the inner surface of the dial, the pillarplate .not having sufficient diameter outside of the dial to support the shoulder either ilush with or above the inner surface of the dial. The front of the movernent,'including the face of the dial, has therefore always projected considerably above the case shoulder, so that the bezel and front cap of the case have had to be made comparatively full or deep to accommodate the said projection of the movement. I
It will be seen that by my improved construction I enable the case shoulder to be made as near the front of the movement as may be desired, the thickness of the marginal portion of the pillar-plate enabling the ICO said shoulder to be madeeither flush with or higher than the inner surface of the dial. The projection of the front of the movement -above the case center can therefore be reduced to a very material extent, so that the projection of the bezel e and front cap f may be correspondingly reduced. As already stated, any reduction of the projection or depth of the front cap may be accompanied by a corresponding,r reduction in the projection or depth of the back cap. Hence the total thickness ordepth of the case can be reduced toa considerable extent by my improvement.
This improvement involves the employment of a dial which is proportionately less in diameter than heretofore,in order that the shoulder-supporting portion of the pillarplate outside of the dial may have sufcient thickness and strength. The said shouldersupporting portion or wall may be utilized as a riser on which the bezel may be snapped or seated. This construction enables the outer surfaces of the front and back caps of eter of the pillar plate below the case shoul- 55 der, said shoulder being above the bottom of the recess of a dial fitted to said recess, as set forth.
In testimony whereof I have signed my name to this speeificatiomin the presence of 4o two subscribing,r Witnesses, this Elth day of December, A. D. 1891.
