BACKGROUND OF THE INVENTION The usual escapement lever in a timepiece mechanism or movement comprises a metallic body secured to an arbor adapted for oscillation and having a pair of divergent arms each of which carries a pallet or a pin for cooperative engagement with the teeth of like radial projections of an escapement wheel. lf pallets are employed, jewels, such as rubies, usually are mounted thereon to resist frictional wear but, in any event, it is difficult to maintain lubrication either of the jewels or the metal as in the case of pins.
SUMMARY OF THE INVENTION An escapement lever according to the present invention comprises a metal lever body, preferably having a safety pin at one end, the other end of which terminates in a pair of divergent arms respectively supporting a pallet or a pallet pin. The pallets or pins and, conveniently, the lever body, are coated with a hard metal such as electroless nickel, electroless chrome or a hard alloy such as cobalt-rhenium alloy, which has a low coefficient of friction and to which a lubricating oil of the type, for example, known as Synt-A-Lube, readily adheres. The escapement lever, including the safety pin and pallets may be stamped from a metal plate which then is coated with the hard metal or individually coated pallets or pins may be mounted on a lever body.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of an escapement lever comprising pallets integrally formed therewith;
FIG. 2 is a cross-sectional view taken on line 2-2 of FIG. 1;
FIG. 3 is a fragmentary plan view of a modified lever with individually supported pallets;
FIG. 4 is an enlarged fragmentary cross-sectional view taken on line 4-4 of FIG. 3;
FIG. 5 is a fragmentary plan view of an escapement lever having pallet pins, and
FIG. 6 is an enlarged fragmentary cross-sectional view taken on line 6-6 of FIG. 5.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawing, specifically to FIG. 1, an escapement lever for a timepiece movement, in accordance with the present invention, comprises a lever 10 of elongated configuration having at one end a safety pin 12 and at the other end a pair of divergent arms 14, 14 respectively disposed on opposite sides of the longitudinal centerline of the'lever, each carrying a pallet 16, 16'. The lever 10 is provided substantially on its longitudinal centerline with a bore 18 to receive an arbor 20 by which the lever is mounted for oscilla- I tion with respect to an escapement wheel, not shown.
According to the invention, the lever shown in FIG. 1 comprises a metal body which may be coated by a layer 24 of hard metal. The body may be blanked from any suitable metal such as brass, german silver, an alloy of one-third each of Cu, Ni and Mn, or steel, either before or after coating, and the hard metal preferably comprises electroless nickel, an alloy of nickel and phosphorus containing from about 3.5 to 11.5 percent of phosphorus, the rest of the composition being constituted by nickel.
The lever body is subjected to a finishing operation to impart cold rolled properties thereto and provide a hardness of about 600 HV (hardness in the Vickers scale). If desired, the lever may be subjected to heat treatment to increase the hardness by precipitation of a phase. For the foregoing purposes, to increase the hardness up to about 800 HV, the lever may be subjected for about one hour at 600C or for about 10 hours at 260C.
After such heat treatment the coating has a coefficient of friction of about 0.2 and after this coating, for example, the area of the pallets l6, 16, has been lubricated, the coefficient friction is reduced to about 0.008. The electroless nickel is chemically deposited by dipping the lever body in a suitable bath to obtain a coating having a thickness of preferably less than t. Further, it is possible to coat the escapement lever by electroless nickel, e.g. by introducing the piece in a bath such as Enplate No. 415 or Niklad 792. The cold rolling effect produced by the finishing operation establishes a greater adhesion between the coating and the metal of the body.
Alternatively, the hard metal may comprise electroless chrome or a hard alloy such as a cobalt-rhenium alloy. A suitable bath may comprise Duralloy to form a coating of electroless chrome or a bath composed of 60 g/l of cobalt sulfat (C080 7 H 0), 66 g/l/ of citric acid (COOH) CH C(OH) (COOH) CH COOH, 10 to 30 g/l of perrhrenate of potassium (K-Re0,) and about 10 g/l of perrhrenate of ammonium (NH -ReO as regenerator, to form a coating of an alloy of cobalt and rhenium. In the latter bath the density of of current should be 2 to 12 Ampldm the pH about 7.6 and the temperature about C. Such coatings may be subjected to the finishing operations.
According to embodiments of the invention, the pallet members, whether pallets having substantial flat operative surfaces or pins having cylindrical surfaces, may be produced separately, at least their operative surfaces coated with the hard metal, and fixed to the lever. For example, as shown in FIGS. 3 and 4, a lever 10a may have arms 14a, 14a divergent from an arbor 20a. The arms may have their extremities in the form of jaws defining slots 26, 26 within which are fitted pallets 16a, 16a, respectively, and which may be secured by any suitable bonding such as solder or adhesive. The pallets may comprise metal bodies 28 completely covered with a coating 30 of the hard metal or the coating may be limited to the operative surfaces of the pallets, that is those surfaces which operatively engage the escapement wheel.
Similarly, as shown in FIGS. 5 and 6, pins may be substituted for pallets. In this embodiment, a lever 10b has arms 14b, 14b divergent from an arbor 20b and the extremities of the arms have bores 32, 32' respectively carrying pins 16b, 16b which may comprise bodies 34 having a hard metal coating 36. Obviously, the pins may be suitably bonded in the bores. The coating of the individual pallet members, whether pallets or pins, may be effected in the same manner as previously described and the coatings have the same characteristics as previously described. Moreover, the pallet members may be fixed to the levers prior to coating and thereafter both the lever and pallet members coated.
