WATCH-GAS E.

SPECIFICATION forming part of Letters Patent No. 343,576, dated June 15, 1886.

Application filed June 2, 1894.

To all whom it may concern:

Be it known that I, MILEs XV. EVANS, of New York city, county and State of New York, have invented new Improvements in Cases for Open-Face Vatches, whereby the same are rendered dust-proofiboth at the opening joints of the case and at the stenrwinder, of which the following is a specification, reference being had to the drawings forming part thereof, in

which Figure 1 is the case, open-faced, containing the dial in its place. Fig. 2 is a sectional view of Fig. 1 on line war, the dialremoved. Fig. 3 is a face view of the bezel, showing withinit the notched or scalloped disk and the screws attaching the disk to the bezel. Fig. 4 is a face view of Fig. 1, the bezel being removed. Fig. 5 is a sectional view of the entire case toward the stenrwinder, showing the construction of the bezel with the protection against dust, the pendant likewise provided, and the mode of attaching the parts together. Fig. 6 is a face view of the disk used to connect the bezel to the other part of the case. Fig. 7 isa face view of a washer used in the arbor of the case. Fig. Sis the universal joint, so operated that the works of the watch can be removed from thecase without removing the arbor or winding-crown; and Fig. 9 is a sectional view of Fig. 6 on line 1 9 My invention consists in improved cases for watches, stem-winders or otherwise, and openfaced, and so constructed as to render said cases dust-proof, or nearly so; and it consists, first, of a compressible substance, in combination with a disk and bezel, so that no dust can creep through, and second, with a stem winder, also rendered dust-proof.

In the drawings Irepresent the face or dial by letter A.

B is the bezel.

Cis theinner or center rim, in which are fastened the works of the watch, and is so made that it may be set in and taken out, carrying the works with it.

D is a very thin disk or rim, of steel or other metal, having part of its body at certain desired distances cut away, as at (Z (Z d. This disk has the flanges 11, made in such amanner as to leave projections e e c, which project out beyond the arbor f ff.

Serial No. 133,514. (No model.)

The disk is held fixed in bezel B by means of the screws h h It, so as to prevent its slipping around in the bezel.

E is the back of the watch, which may be made with its sides 9 g of one piece, like the old English bulls-eyes, or made in detached pieces from sides and soldered to the side.

G are screws or lugs fixed in or secured firmly on the face of the upper side of case E, Figs. 2 and 4t, and arranged at desired distances apart, and are ,to receive under the head z'the bezel B by engaging with the disk D under its surface It, and thereby locking the bezel down tightlyto the center rim, as hereinafter described. The surface L at one end is slightly inclined outward from the surface of the bezel, sufliciently to allow the head of the screw or lug to enter between the disk flanged out and the bezel, but steadily decreasing till it is almost tight against the body of the bezel B, and thus prevents the head of the screw from passing iartheaand holds said head tight in position until pressure is applied, and the bezel is turned back on its path and reaches the cut-away portions d and is released.

Z is the groove running around the entire case in the sides and in which is placed the packing m, which may be of any suitable material, on which packing the flange or edge of the bezel is tightly held.

J is the pendant, through which the universal single joint L is passed, the same being screwed into the winding-crown at a, and the other end of which is passed into the aperture 1) in center rim, and that end, 0, is loosely operated on the joint-pin and socket r, Fig. 5. It will be readily seen that by use of this joint the cap of the stem-winder need not be so constructed as to be pulled out,so as to relieve the center rim and allow its removal, with the works, out of the case when it is desired to clean them. The end or arm o,projecting into the rim 0, is adapted to engage with the winding-stud of the movement, and provided with suitable connections therefor. The neck M made either in one continuous piece with case of watch, or separate and attached to the back-has circular extensions t t, Fig. 5, which fit into recesses or cavities s s in winding cap or crown N. On the inner ends of t t is placed the washer P, which may be duplicated, as shown, by cutting off one part of lug t t" and putting on a washer, P, and then placing said part back over the washer and adding a second washer, P, and holding it The center rini may be snapped into the 'holding-case or back by means of a common snap at \V, set in atits 1'ear,ifdesired, or remain -unfastened. center rim, 0, placed in the case E, is snapped down into the same.

over dial A. The groove l has placed within it the packing m,'which is held securely in place, whether the rubber is bound by bezel or not. rim and shut down onto the upper face of case E, and turned around until the screw orlug G falls into the apertures d, or any one of them. A further turn is then given to the bezel till the lug G, with its head, has passed behind projecting flange K, and ispressed up till the impingement is so great that it can be pushed no farther. The bezel has, perhaps,

engaged in its disk D all three of the screws or lugsatleast two of them are soengagedand being pressed down onto the packing m is madewatertigl-it. The air, dust, and water can not then enter between sides of case E and bezel B, nor can they enter by way of the wind- It is now desired to remove thebezel and works for cleaning. The reverse motion will carry the bezel back so that the lugs G will enter arborf and init is now plainly evident that the The bezel B, containing i the glass and its disk D, is readyto be placed The bezel is placed over the center' stantl-y release all hold on disk D. The bezel removed, the center rim,O,is snapped up, and the universal joint allows it to be taken off without removing or withdrawing the pendant.

I am well aware that packing has been used before, but in an entirely different way, not confined nor so constructed that it could be renewed when worn out.

I do not claim a single case forming the back of a watch,except in combination, as that was :long since used in old English watches, and is not new; but

What I do claim as new is- 1. In combination with the center rim, 0, disk D, and case E, with lugs or screws G, groove Z, with removable packing m, movable center-rim, '0, having aperture 1), of a universal joint,substantially as described, and for the purpose specified. I

2. The combination of a-winding-arbor and neck, N, having projections t t,washer P,with

core E, center rim, 6, universal joint L, and winding-stem, with its recesses, so that the works may be removed without pulling out the arbor or winding stem, substantially as described, and for-the purpose specified.

3. The bezel B, having disk D,with flanges, arranged as described, with case E, having fixed in the face of its sides the screws or headed lugs G, groove 1, packing m, center rim. 0, with aperture 1). universal joint L, winding stem or crown N, with cavities s s, the neck having projections tt entering there in and closely fitted-by means of washers P in said cavities, so that no moisture or dust can enter therein, and the center rim readily re- =niovable without drawing pendant and winding-cap back, and without disengaging any screws thereof, substantially as described,and for the purpose specified.
