Description

Feb. 19, 1952 E. DITESHEIM 2,586,419
WATCH MOVEMENT FASTENER Filed April 5, 1951 I van for Edoua d DIfeSbQ/hv Patented Feb. 19, 1952 QEFFIC WATCH MOVEMENT FASTENER.
Edouard Ditesheim, La Chaux de Fonds, Switzerland Application April 3, 1951, Serial No. 219,091 In Switzerland April 6, 1950 1 Claim.
This invention relates to a timepiece. This timepiece is characterized by the feature that the movement is fixed into the case by two devices situated substantially at 180 from one another, one of these devices comprising a resilient tongue removably attached to the movement, the free extremity of this tongue bearing in a cavity of the case so as to press a flange of the movement against the outer face of a wall of this cavity.
The accompanying drawing illustrates one embodiment of the invention by Way of example.
Fig. 1 is a plan view of the timepiece with partial sections, the dial removed, and
Fig. 2 is a section on line II--II of Fig. 1.
In these figures, the case illustrated comprises a back 5, a bottom 2, a rim 3 and a glass 4.
The movement comprises a plate 5, a dial 6 and an oscillating mass 1 for winding. A resilient tongue 9 is fixed on to the plate by a screw 9. The free extremity of this tongue projects beyond the periphery of the movement and penetrates into a milled groove It] in the back I. On the same diameter as this tongue 8, that is to say at 180 from this tongue, a washer II is fixed by a screw 12 to a block l3 which is itself fixed to the plate by means which are not shown. The head of the screw I2 is situated on the side facing the bottom 2. The washer H projects from the movement and penetrates into a cavity 14 in the back I.
The movement is set in place in the following manner: the tongue 8 is first of all fixed to theplate and then introduced into the cavity Ill, after which the movement is inserted obliquely into the back and fitted in. The washer II is then set in place and fixed by the screw l2. The bottom and the rim can then be mounted on the back.
It is to be noted that this arrangement allows the mass 1 to pass under the tongue 8 so that the mass can traverse a sector extending over nearly 360; the block it serves as an abutment for the mass 1 and for this purpose carries shockabsorbent springs which are not shown.
What I claim is:
In a timepiece with automatic winding by means of an oscillating mass, comprising a case in which is provided a cavity, a movement provided with a flange and two devices situated substantially at 180 from one another for fixing said movement in said case, one of these devices comprising a resilient tongue removably attached by one of its extremities to the movement, the free extremity of this tongue bearing in said cavity so as to press said flange of the movement against the outer face of a wall of this cavity, the feature that a block is used as an abutment for the mass and that the second device for fixing the movement into the case is situated in said block.
