KAUFMAN SHAYA AND MORRIS SHAYA, OF NEW YORK, N. Y.

WATCH.

Application filed October 1, 1924. Serial No. 740,997.

To all whom it may concern:

Be it known that we, KAUFMAN SHAYA and MORRIS SHAYA, citizens of Poland, and residents of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved WVatch, of which the following is a full, clear, and exact description.

This invention relates to improvements in watches, and while we shall hereinafter refer to the device specifically as a watch it is obvious that the invention may apply with equal facility to a clock or any other time piece.

An object of the invention is to provide a watch in which the hands are set and the spring wound by a longitudinal reciprocation imparted to avplunger connected to a knob or button which corresponds in appearanceto the ordinary knob in general use.

Heretofore watches have almost universally been wound and set by the turning movement of a knob, and it is the purpose of our invention to carry out this operation by a reciprocation or longitudinal movement of the knob.

With these and otherobjects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view in elevation of a watch with the back plate of the watch case removed and illustrating somewhat diagrammatically our invention;

Figure 2 is a view taken from the opposite side of the watch, showing portions in section for clearness;

Figure 3 is an enlarged fragmentaryview illustrating the downward position of one of the ratchet racks; I

Figure 4 is a similar view illustrating the position of the rack in its upward move ment; 7

Figure 5 is a fragmentary edge view of the watch;

Figure 6 is a fragmentary view showing in detail the position of the plunger controlling spring;

Figure 7 is a fragmentary view insection on the line 77 of Figure 1.

1 represents the case of our improved watch in which a plate 2 is secured, this plate constituting the ord nary support for but for purposes of illustration we the works ofthe watch. The case 1 is provided with a sleeve 3 and a ring 4 for con necting the same to a watch chain.

5 represents a cap or knob which is adapted to move longitudinally on the outer end of the sleeve 3. This knob 5 has a plunger 6 fixed thereto, the inner end of said plunger projecting through an opening 7 in the case land also through a bifurcated spring 8 fixed in the case.

A finger 9 is fixed to the lower end of the plunger and located at right angles thereto, and said plunger, throughout a portion of its length, at least,is angular in cross section so that by reason of its engagement with the bifurcated spring it will be resiliently held in either of the operative positions, as is clearly illustrated in Figure 6.

' 10 and 11 represent longitudinally movable ratchet racks, which engage ratchet wheels 12 and 13, respectively. These racks are held in contact with the ratchet wheels by a double bowed spring 14: and are provided with lugs 15 projecting through'slots 16 in plate 2 and in the path of movement of the finger 9.

Springs 17 exert pressure against the lugs 15 to hold the latter in one extreme position and return them to such position when permitted. Also it will be notedithat a coil spring 18 is provided in the sleeve 3 around the plunger 6 and exerts an outward pressure on the knob or cap 5 to hold the plunger in its outward position.

The ratchet wheel 12 controls the wind ing of the spring of the watch and the ratchet wheel 13 controls the setting of the hands of the watch, the latter being illustrated in dotted lines in Figure 1 and given reference numeral 19.

It is, of'course, to be understood that we do not limit ourselves to any particular construction of watch works as our invention is capable' of use with any .type of works, have shown intermeshing gears 20 and 21 opera vtively connected with the hands 19 and gear wheels 22 and 23 operatively connected to the arbor 2 1 of a watch spring (not shown).

The ratchet wheels 12 and 13 are fixed to shafts 25. The latter are projected through slots 26 in plate 2 and have pinions 27 on their opposite ends. Springs 28 hold the parts in normal position with the pinions 27 removed from the gears with which they are engaged soas not to interfere with the ordinary watch movement, but when the racks 10 and 11, respectively, are moved downwardly they not only turn the ratchet wheels 13 and the pinions fixed thereto but they also move the pinions into mesh with their respective gear trains so that the watch may be wound or the hands set as the case may be.

The knob or cap 5 may, preferably, be somewhat oval-shaped, as indicated in Figure 5, so that one portion thereof constitutes a pointer and may register with letters or captions on the edge of the case to indicate whether the knob is in position for setting or winding the watch, as indicated in Figure 5.

Assuming the parts to be in the position shown in Figure 2, a reciprocation of the plunger 6 due to the inward and outward movement of the knob 5 will cause the finger 9 to engage the lug 15 of ratchet bar 11 and through the medium of the parts described above will cause the hands of the watch to turn to set the hands at the position desired. This operation or reciprocation can be repeated as often or as little as desired, the springs 18 and 17 causing the parts always to return to normal position after inward movement.

If it is desired to: wind the watch, the knob 5 is given a turn of 180 to bring the finger 9 in position to. engage the lug 15 of rack 10, and a similar operation imparted to this rack will wind the spring of the watch through the medium of the mechanism above pointed out.

:Various slight changes and alterations might be made in the general form of the parts described without departing from our invention, and hence we do not limit our selves to the precise details set forth but consider ourselves at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

We. claim 1. A watch, comprisii'ig a case, a pair of ratchet wheels in the case, one of which operatively controls the setting of the hands of the watch and the other operatively controlsthe. winding of the spring of the watch, ratchet racks engaging the respective ratchet wheels, a reciprocating plunger, and a linger on, said plunger adapted to be positioned to operatively engage either of said racks.
