Precision damper bearing

Resilient bearing mounting especially for instruments - has Z-shaped deformable portion between bearing and housing

The bearing mounting, made from firm but resilient plastics, has a central portion containing a bearing for a spigot and an outer wall for supporting the mounting in a rigid housing. Between the central portion and outer wall there are two intermediate walls which form together with the outer wall a concertina or 'Z' shape whereby the mounting has radial resilience. The free axial end of the outer wall and the opposite axial end of the central portions are located between end faces of the housing thereby providing axial location. An end wall of the housing may have a tapered annular rib engaging between the intermediate walls to provide bias into a radial location.

Bearing for a staff balance of a clock piece and clock piece provided with such a bearing

The bearing has a bush (41) enclosing balls whose axial displacement is limited by a pivot against element. An element is formed with a hole for insertion of pivot of a staff balance (50) of movement in a space between the balls, where the bearing is arranged to pivot the balance between the balls. The balls and the pivot against element are made of non-metallic material. The balls, element and the pivot against element are assembled inside the bush in a permanent and unremovable manner. The balls form an opening to allow passage of the pivot and prevent release the element through the hole.

Shock absorbing bearing for watch spindle - has resilient plastic bearing block mounted in circular housing

A shock absorbing bearing for the spindles of watches etc. has a circular housing (1) with two concentric recesses (1a, 1c). A bearing block (2) of resilient plastics has a spigot (2a) which is a close fit in the inner recess (1a). The bearing block (2) has a flange (2f) which fits in the recess (1c) with a radial clearance and is secured by peening over the lip (1d). The end of the spindle (3) fits in the bore of the central portion (2c) of the bearing block (2) and is attached to the outer wall (2e) by the end flange (2d). This form of bearing block provides flexibility to resist shocks in both lateral and axial directions.

Clockwork assembly, especially for wrist or pocket watches, in which the working surfaces are coated with DLC (diamond like carbon) to largely prevent wear and thus make maintenance almost unnecessary

Mechanical clockwork assembly, especially for wrist or pocket watches has a mechanical oscillation system and a mechanical escapement with an escapement wheel (1) and an anchor (3). The functional elements of the escapement wheel are at least partially coated on their operating surfaces with a DLC (diamond like carbon) coating. An Independent claim is made for a mechanical clockwork assembly, especially for wrist or pocket watches with plate, plate element and balance-wheel arbor where the contact surfaces of the moving parts are coated with DLC.

897,031. Bearings. PARECHOC S.A. Jan. 25, 1961 [Feb. 2, 1960], No. 2864/61. Class 12 (1). In a shock-absorbing bearing for a watch &c. a bearing body 7 is axially slidable in a bush 9 which has an internal shoulder 9a abutted by the body 7 when urged by a spring 10, and has an external flange 9b which is urged against a shoulder 1b of a housing 1 by a spring 11. Both springs abut a cap 5 which is screwably attached to the housing, and the body 7 has a recess 8 to receive a pin 3. In an embodiment, as shown in Fig. 2, a disc 23 fixed in a housing 21 limits the lateral movement of a pin 12 held in a bush 16 and engaged by a bearing 14 in an arbor 15. In an embodiment as shown in Fig. 3, a spring 25 having three equi-spaced deformed tongues 25a is inserted through recesses 28 of a housing 27 and into an annular groove therein, the spring 25 being rotated to secure it in bayonet fashion. A spring 24 which urges the bearing towards a pin abuts said spring 25. The springs 11, 22 may be replaced by coil-springs.
