WINDING AND SETTING MECHANISM FOR WATCH MOVEMENTS Filed OGl'., 14, 1947 Patented Apr. 3, 1951 WINDING AND SETTING MECHANISM FOR WATCH MOVEMEN TS Erich Schmitz, Granges, Switzerland Application October 14, 1947, Serial No. 779,822 In Switzerland December 14, 1946 2 Claims.
The invention relates to a setting mechanism for watch movements in which the winding stem is coupled to an extractor enabling it to position it at will in either the winding or setting position, the rotational movement of this stem being carried out in either of these positions by means of a toothed crown guided in a slot of the casecentre embodied in the watch movement.
The case-centre consists preferably of several concentric pieces litted into one another and cooperating in such a manner as to hold in position the toothed crown used for operating the winding stem.
The drawing represents, by way of example, an executional form of the watch-case fitted with the winding mechanism and the setting organs according to the present invention.
Fig. 1 is a sectional view along the axis of the winding stem and Fig. 2 is a part sectional view on the line II--II of Fig. 1.
The case-centre of the represented watch-case (see the right portion of the drawing) is composed of several pieces. There is a central body I0, on the circumference of which is fitted snugly in the notch I2 a ring II, in which engages the circle I3. The whole is dimensioned in such a manner that the mutual strain of the pieces contributes tc maintain in position the circle and this ring on the central body I0, providing between them a slot I4 in which is introduced the toothed portion I5 of a crown I6, which slightly projects over the exterior Surface of the back and which is knurled for operation by the finger tip.
The winding stem I1 which enters into the movement i8, is provided at its exterior end with a toothed wheel I9 and with a button 2t) separated by a throat 2I. With this throat between the toothed wheel and the button engages the forked portion 22 of an extractor '23, the head 24 of which is recessed in a milled opening in the circle I3. The recess is suiliciently large for the introduction of the finger nail under the head 24 in order to move the extractor and to bring the toothed wheel I9 and the button 20 into the position shown in dash-dotted lines on the left of Fig. l. The Winding stem is then in setting position and, owing to the tooth length of the toothed portion I5 of the crown, the toothed Wheel I9 may be rotated in either position when the knurled portion of the crown is being actuated by the finger tip.
What I claim is:
1.1A watch case of the character described comprising a body of a cup-shaped formation having a closed back and an open face, a crystal carrying bezel cooperating with the rim of said cup-shaped body for closing the face of the same, a winding and setting stem extending through the peripheral wall of the cup-shaped body and axially shiftable between winding and setting positions, a pinion carried by the outer portion of said stem, said cup-shaped body having an annular recess in the outer surface of the peripheral wall adjacent the back thereof, a toothed crown rotatably mounted in said annular recess and meshing with said pinion, said toothed crown having an annular knurled portion projecting beyond the surface of a portion of the back of said cup-shaped body for rotation of the crown, and rings cooperating with each other and embracing the cup-shaped body and crown for retaining said crown in said recess, the teeth of said crown being of sufficient length to engage the pinion on the stem in both of its positions of shifting.
2. A watch case of the character described comprising a body of a cup-shaped formation having a closed back and an open face, a crystal carrying bezel cooperating with the rim of said cup-shaped body for closing the face of the same, a winding and setting stem extending through the peripheral wall of the cup-shaped body and axially shiftable between winding and setting positions, a pinion carried by the outer portion of said stem, said cup-shaped body having an annular recess in the outer surface of the peripheral wall adjacent the back thereof, a toothed crown rotatably mounted in said annular recess and meshing with said pinion, said toothed crown having an annular knurled portion projecting beyond the surface of a .portion of the back of said cup-shaped body for rotation of the crown, rings cooperating with each other and embracing the cup-shaped body and crown for retaining said crown in said recess, the teeth of said crown being of suiiicient length to engage the pinion on the stem in both of its positions of shifting, a knob on the outer portion of said stem, a stem shifting member extending from said knob through one of said rings and movable in a direction parallel to the axis of said stem, the outer peripheral portion of one of said rings having a recess, and a finger engaging head on said stem" shifting member housed in said last recited recess when the stem is in the inner of its shiftable positions.
