MEANS FOR SECURING WATCH-MOVEMENTS IN THEIR CASES.

SPECIFICATION forming part of Letters Patent No. 783,611, dated February 28, 1905.

Application filed December 31,1903. Serial No. 137,272.

To all whom it 'lruty concern: tween the head of the bolt and the spacing Be it known that I, FeANgioIs OnEvILLA'r, a member. citizen of Switzerland, residing at Bienne, The movementis preferably provided with Canton of Berne, Switzerland, have invented one or more recesses cf in its periphery and 5 certain new and usefulImprovementsin Mean's adapted to receive the spacing members 1 I), for Securing WVatch Movements in Their which project slightly beyond the periphery Cases, of which the following is a clear, full, of the movement.

The heads of the screws 0 are adapted to project (when they are turned into the position shown at the left of Fig. l) outwardly beyond the periphery of the movement at the lower edge of the dust-band, and the screws are long enough so that when their threads are in engagement with the movement there will be a space left between the upper side of the head of the screw and the lower edge of the dust-band I) in order to receive the flange or extension 11' so that the dust band or support may be seated upon the upper side of this extension with the head of the screw below it. The screws 0 preferably are of a length sufficient to screw into the front plate p. This is of a distinct advantage, because by it the strain comes directly upon the front plate and it is not so apt to be sprung as would be the case if the screws were merely tapped into the lower part ofthe movement and did not extend into the front plate.

It will be obvious that many changes may be made in the construction shown without departing from the scope of my invention as claimed, and 1 therefore do not limit myself to the particular construction described and illustrated.

4. In combination, a watch case-center having an inturned flange at its rear side, a watchmovement having a flange at its periphery, a surrounding dust-band having an internal shoulder against which said latter flange rests, said dust-band being turned inwardly at its rear side and resting on the flange on said casecenter, said movement having one or more re cesses in its periphery, a screw tapped into the under side of said movement and located in said recess and having a head located below the lower edge of said band and adapted to project beyond the periphery of said movement and the inner periphery of said flange on said case-center, whereby said flange on said case-centeris held between said dust-band and head.

5. In combination, a watch case-center having an inturned flange at its rear side, a watchmovement, a surrounding dust-band supporting said movement, said dust-band resting on the upper side of said case-center flange, said. movement at its rear side being adapted to project into the opening formed by said casecenter flange, a spacing member located between said dust-baml and movement and resting against the upper portion of said case-center shoulder and supporting said movement, and one or more screws tapped into the under side of said movement and having a head located below the lower edge of said case-center flange and adapted to project beyond the same whereby said latter flange is held between said spacing men'iber and said head.

(3. 1n cmnbination, a \vatcl1movementhaving one or more recesses in its peri1')hery, a screw tapped into the under side of said movement and having ahead adapted to project beyond the periphery of said movement, and a spacing member located in said recess above the head of said screw and also projecting beyond the periphery of said movement.

7. in combination, a watch-movement having one or more recesses in its periphery, a screw tapped into the underside of said movement and having its shank located in said recess, and having a head adapted to project beyond the periphery of said movement, and a spacing member also located in said recess above the head of the said screw and also projecting beyond the periphery of said move ment.

8. A watch-movement having a flange at its periphery, a surrounding dust-band having an internal shoulder against which said flange rests, said movement having one or more recesses in its periphery, a screw tapped into the under sideof said movementand having a head located below the lower edge of said band and adapted to project beyond the periphery of said movement, and a spacing member located in said recess above thehead of said screw and also projecting beyond the periphery of said movement.

9. in combination, a \vatchcase-center having an inturned flange at its rear side,a watchmovement, a surrounding dust-band supporting said movement, said dust-band resting on the upper side of said case-center flange, said movement at its rear side being adapted to project into the opening formed by said e: secenter flange, and one or more screws tapped into the under side of said movement and having a head located below the lower edge of said case-center flange and adapted to project beyond the same whereby said latter flange is held between said dust-band and said head.

10. The combination with a watchcase-center having a flange towards its back of smaller diametrical opening than the opening at its front side, a movement adapted to enter the case-center from the front side and project into the opening formed by said case-center flange, and means for holding the movement in place, comprising adjustable tension members secured to the movement and engaging the back or outer side of the said flange of the case-center, and one or more separable spacing members engaging the front side of said flange and the movement.

11. A watch-movement having a flange at its periphery, a surrounding dust-band having a shoulder against which said flange rests, said movement having one or more recesses in its periphery, one or more screws tapped into the under side of said movement and having a head located in said recess and below the lower edge of said band and adapted to project beyond the periphery of said movement at that point] 12. As a means for fastening a watch-movement to its case from the back of the watch, the combination of a case-center having front and back inward extensions, a watch-movement sufficiently small to be inserted from the front, said movement including a front movement-plate detached from said front extension and a dust-band sufliciently small to come within the front extension and rest on the back extension, a screw, a threaded end of which screws into said movement-plate and the head of which bears against the said back extension so as to draw the movement-plate toward said back extension upon screwing up the screw, said dust-band being clamped between said movement-plate and said back extension.

13. A watch-movement havinga peripheral flange, a movementsupport outside of said movement below said flange, and one or more screws inside of said support and screwing into said movement from the rear and having a head below, and projecting outwardly beyond the periphery of said movement at, the lower edge of said support, said screw being of a length sufficient to form a space between said support and head while the thread of said screw is in engagement with said movement, said space being adapted to receive a part of a watchcase.

ll. A watch-movement having a peripheral a movement-support in the form of a ring outside of said movement below said flange, and one or more screws inside of said ring and screwing into said front plate from the rear and having a head below, and projecting outwardly beyond the periphery of said movement at, the lower edge of said ring, said screw being of a length sufficient to form a space between said ring and head while thethread of said screw is in engagement with said front plate, said space being adapted to receive a part of a watchcase.
