RESILIENT SECURING MEANS FOR WATCH MOVEMENTS Filed March 11, 1947 I N V EN TOR. #:wz/ 65(55? Patented Dec. 30, 1952 RESILIENT SECURING MEANS FOR l/VATCH MOVEMENTS Henri Gerber, Bienne, Switzerland, assignor to Omega Louis Brandt & Frere S. A., a company of Switzerland Application March 11, 1947, Serial No. 733,878 In Switzerland March 8, 1946 Section 1, Public Law 690, August 8, 1946 Patent expires March 8, 1966 12 Claims.
This invention relates to watch movements particularly for watertight watches.
For holding the movements in watertight watches comprising either a combined bezel and center or a combined bottom and center, fitting rings have hitherto been used in the form of short tubes with very thin walls and with springy tongues, bent towards the center of the watchcase. These tongues were not very efficacious. Besides, they occupied a space between the case bottom and the outer faces of the bridges of the base plate, which augments the total height of the timepiece.
The aim of the present invention is to avoid this increase in height while fixing the movement in the watchcase by means of an elastic pressure, i. e., while leaving a certain play to the tolerances necessary for the packings.
An important feature of the Watch movement according to the invention is that, for being held in place in the watchcase, it comprises at least one plate spring mounted on the circumference of the movement and tensioned by the closing of the watchcase, that is, either by the bottom or by the bezel.
By preference, the plate spring comprises a fixing strip and a resilient strip connected with each other by at least one of their ends. The said fixing strip may either be screwed to or hooked onto the circumference of the base plate of the movement or fixed to this plate by means of eyelets bent into a plane parallel to that of the base plate.
The accompanying drawing illustrates, by way of example, an embodiment of a watch movement according to the invention, and different forms of the plate springs used in this movement.
Fig. 1 shows, in a perspective view and only in so far as is required for the comprehension of the invention, the base plate of the movement of a watertight watch, and
Figs. 2 to 6 are perspective views illustrating difierent forms of plate springs which can be used in the movement of Fig. 1.
Referring to Fig. 1, l designates the base plate of the watch movement. It ha the usual circumferential rim II by means of which it is supported on a corresponding part of the watchcase, for instance, pressed against a shoulder of the bezel by the bottom screwed to the combined bezel and center of the watchcase.
A plate spring i3 is fixed to the plate I by means of screws I2. This plate spring comprises a fixing strip l4 and a resilient strip [5 which are connected with each other at their ends, and
2 are separated from one another by a slot, |6.'. The resilient strip [5 has in its middle 2. projec-- tion I! on which a pressure is exerted by thebottom of the watchcase in order to make the flexibility of the resilient strip l5 effective and to hold in this way the movement in place.
The movement plate shown in Fig. 1 has two plate springs lying diametrically opposite each other. However, there might be three springsdisplaced by with regard to one another.
The movement according to the invention: might also carry plate springs of the kind shown.- in Fig. 2. This plate spring comprises elongated; openings through one of the ends of which the: head of a screw can be passed, screw and open' ing forming together a keyhole locking means;
In the design of Fig. 3 the spring plate com-- prises eyelets l8 bent into a plane parallel to that. of the base plate and serving for fixing the spring." plate to the movement.
The plate spring shown in Fig. 4 has a resilient spring l5 split in its middle so as to form two elastical arms whose projections I! are sup-- ported on the bottom screwed to the remaining: part of the watchoase.
The plate spring as illustrated in Fig. 5, com-- prising likewise two eyelets l8, has a resilient spring is which is only at one end connected with the fixing strip l 4.
In the design of Fig. 6 the fixing strip is cut out. The remaining ends 20 carry eyelets ill for fixing the plate spring to the base plate of the movement to which it belongs.
