BY (2W5? M Patented Oct. 9, 1951 TICKING TOY WATCH Lawrence Wise, Cedarhurst, N. Y., assignor to Ever Tick Corporation, Floral Park, N. Y.', a

corporation of New York Application June 1, 1950, Serial No. 165,416

16 Claims.

My present invention is an improvement of the invention described in my application Serial No. 135,730, filed December 29, 1949, and relates primarily to the specific commercial embodiment of the toy watch made in accordance with the disclosure thereof.

The invention is directed to a ticking element for a toy watch and to other operative elements of the watch so arranged as to simplify manufacture and assembly.

The objects of my invention will become apparent in the following description and drawings in which:

Figure 1 is a plan view of my novel toy watch with the back removed.

Figure 2 is a view of the face of my toy watch.

Figure 3 is a cross-sectional view taken on line 3-3 of Figure 1.

Figure 4 is a view in perspective of the interior of the watch case.

Figure 5 is a cross-sectional view corresponding to that of Figure 3 showing the method of assembly.

Figure 6 is a diagrammatic view showing the method of operation of the ticking element.

Referring to Figures 1 to 4, I have here shown the front half l of a watch case to which any suitable back cover may be secured.

The front half l0 of the watch case has a front surface H and a wall I! which may be annular in the case of a circular front wall I l but which in any event follows the outer perimeter of the front wall i i and is perpendicular thereto.

The back cover l3 may be secured to the free end of the wall (2 or tightly fitted over it in any suitable manner.

Gear wheel 16 has hands I9 struck up therefrom. Hands H (as seen in Figure may be passed through opening ill in the front wall H and then bent over the printed face card 20 which covers the openings in wall I l.

The teeth of gear wheel 16 are bent up as shown to make a type of bevel gear to cooperate with the hand winder knob described below.

The front wall member I l is a single plate having all of the securement elements thereon.

The hand wind arbor 26 is mounted in recess 25 in wall 12 and is supported in lug 25a of wall I I. The pinion 21 and knurled knob 28 are made integral with arbor 26.

Thus, assembly is facilitated. The gear wheel 16 is positioned by pushing the hands l9 struck up therefrom in opening 18 in wall H. The hands l9 pass through face card 20 and, when bent over, position gear wheel 16 and face card 20. The winding element is merely snapped into lug a and is positioned by matching recesses in walls I2 and 13.

The wall l2 may have a bezel 29 to receive a crystal 29a. The face card 20 may be replaced by appropriate lithographing or other printing on the front wall il itself.

The ticking element of my novel toy wrist watch comprises the leaf spring 30 which, as pointed out in application Serial No. 135,730, above referred to, is preferably made of feeler gauge stock approximately .0015 inch thick, inch wide and .875 inch long of oil hardened steel.

One end of leaf spring 30 is welded between the two upstanding lugs 32 struck up from wall II.

The spring 30 is 50 arranged that its width (not its thickness) i perpendicular to the front wall II, but it is supported free of the front and back walls H and I3. The free end of the spring 30 has clamped thereto or secured thereto in any suitable manner a weight 35 so dimensioned that as the spring vibrate the weight 35 will always be clear of the front and back walls of the casing.

A lateral arm is secured on each side to the side of spring 30 by welding on the bent over panel 4|. Arms 40 are engageable with respective lugs It struck up from wall II, as the spring oscillates, to produce a ticking sound.

Thus, the spring 30 may readily be assembled in the watch by placing the same between lugs 32 and applying welding electrodes to the outer surfaces of lugs 32.

When the spring 30 is mounted in the watch case as shown, any movement such as that occasioned by the movement of the watch case either when it is picked up from a store counter and placed to the ear or when it is moved on the wrist to the car will cause the spring to vibrate as a pendulum about its anchor point 32. This motion is illustrated in Figure 6.

I have found with a spring of the type and dimensions above-described a single motion from the counter to the ear, from the wrist to the ear, or from one portion of the counter to the other will produce a ticking lasting for forty seconds or more.

The ticking will occur and continue irrespective of the orientation of the watch-face up, face down or vertical and at any angle.

By this means, therefore, I provide an inexpensive ticker for a toy watch which may readily be incorporated in existing toy watch design and will provide the child with the satisfaction of owning a ticking watch. A watch with my novel elements.

ticking device may, nevertheless, be sold as an inexpensive toy watch in the ten cent stores.

The leaf spring 3fl,the arm 49 and the lug M with which it cooperates to produce the ticking noise are so mounted that for any' normal movement of the watch the oscillations will occur without any inhibiting force. The operability of my device is probably due to the transformation I of kinetic to potential energy and back'again as the weight oscillates. Thus, the energy of'the oscillating weight, which 'is kinetic when the weight is going in one direction, and prior to the engagement of an arm 40 wth a lug l4, changes to potential energy in causing flexure of the spring once such engagement has occurred. Thus, the tick effected by the engagement does not utilize the entire kinetic energy 'of the weight, a large portion of the kinetic energy being then transformed to potential energy in bending the spring. Accordingly, as the spring unbends to swing the weight back in the reverse direction, the potential energy of the bent spring is transformed back into the kinetic energy of the moving weight only to be once more transformed to potential energy upon occurrence of engagement of the other arm 40 with -its respective lug l4. Thus, the cycle of transformation of energy from kinetic to potential is sustained for an appreciable period while the ticking of the mechanism absorbs only a portion of such energy during each cycle. That this explanation is probably true may be inferred from the fact that if a mere spring was set oscillating with a weight at the end intended to strike lugs disposed at the ends of the swing, to produce a ticking sound, it would not work more than one or two cycles because all of the kinetic energy of the weight, and such potential energy as may be stored in the spring, would be absorbed in shock and deformation, however minute, of the abutting The preceding contention has been determined by experimentation and strongly indicates that my theory of operability is correct.

The utilization of two arms 40 against lugs l4 makes the tick rapid and steady.

By the means herein described, a simplified assembly is permitted. The hands and the gear wheel are made of one piece; the winding knob and its gear and arbor are one piece; the ticking spring is accurately positioned by the main support panel or wall.

In the foregoing I have described my invention solely in connection with specific illustrative embodiments thereof.
