Claims.

This invention relates to animated time instrumentsmore particularly to watches and clocks having pictorial animated portions associated with the dial thereof.

In most previous attempts to obtain animated efiects, an undue burden was generally placed upon the movements of the time-piece by virtue of the construction, weight or positioning of the animated components. There has accordingly been an interference with the proper action or time-keeping properties of the device. This shortcoming has been particularly manifest in watches, as distinguished from clocks, since even very slightly animated movements have, with conventional animating mechanisms, necessitated an undesirable draining of power. And in larger clocks, there has also generally been considerable interference with the proper functioning of the time-keeping mechanism when conventional animation-producing components were used, particularly where relatively large animated movements were desired.

It is accordingly primarily within the contemplation of my invention to eliminate the aforesaid shortcomings in devices of the above-mentioned category by providing means to produce attractive animated effects without affecting the normal operation of the time-piece, whereby the invention will be conveniently adaptable for use with delicate watch movements, or with more rugged clock movements where comparatively large animated motions are to be employed.

It is also an object of my invention, in a preferred form thereof, to employ the conventional escapements of watches or clocks to obtain both rotary and oscillatory animated motions, either separately or combinatively. And in the lastmentioned aspect of my invention, it is an object to obtain a coordinated interplay of movements visible at the dial, whereby various animated effects employing two coactive elements may be obtained.

It is a further object of my invention to enable the conventional mechanisms of a watch or clock to be employed without alteration, whereby it will be necessary merely to add certain slightly modified components to produce animated effects.

It is still a further object of my invention to improve the balance of a time-piece mechanism by employing an animated component which will also serve as a counterpoise to the conventionally unbalanced pallet. More specifically, in modern mechanical time-pieces, the pallet is generally constructed with a single long tail flanked at one end thereof by two short arms. According to a preferred form of my invention, an animated component is provided which not only serves its intended animating function, but also serves to give symmetry and balance to the pallet by being disposed oppositely to the tail, thereby bringing the center of gravity of the pallet to the region of the pallet arbor.

It is also within the contemplation of my invention to render it adaptable for use with various types of escapements, including jewelled detached lever escapements, cylinder escapements, etc., as well as with any model of mechanical or electrical watch or clock which utilizes an escapement for time-keeping. And it is also within my contemplation to employ animated components or riders that may be disposed either below the plane of the dial, in the plane thereof, or thereabove.

Other objects, features and advantages will appear from the drawing and the description hereinafter given.

Referring to the drawings:

Figure 6 is a fragmentary section of Fig. 5 taken along line 6B.

Figure '7 is a perspective View of the assembly of the pallet and oscillatory rider of Figs. 5 and 6, and

Figure 8 is a plan view of a watch showing the dial and animated component according to the structure of Figs. 5 to 7.

In the form of my invention illustrated in Figs. 1 to 4, a construction is shown wherein there are two animator components, to wit, the oscillatory legs ill and the intermittently rotatable wheel I I. As will more clearly hereinafter appear, the leg I!) of the illustrated tricycle rider moves in coactive relation to the wheel I0, creating the illusion that the wheel is being actuated by the leg, the cyclic relation being deter- 3 mined by the operation of the mechanism to which components In and H are attached.

The watch illustrated contains a conventional escape wheel l2 with pinion l3 and arbor I l containing rear and front extension shafts l5 and I6, respectively, rotatably mounted upon rear bridge I? and front wall lB, respectively. In operative engagement with the escape wheel I2 is the pallet IS, the jewels 2t being engageable with the teeth 2! of the wheel. The pallet is supported upon the arbor 22 which has rear and front extension shafts 23 and 24, respective. ly, rotatably mounted on bridge ll and front wall 18. The escape wheel and pallet are substan-, tially like conventional watch elements, except for one important difference, to wit, the front shaft extensions l6 and 24 are elongated to the region of the dial 2% so as to be in engagement with animator riders.

More specifically, the shaft extension it of the escape wheel [2 has force-fitted thereover the tube 26 axially secured to the rotary rider ll, shown as a wheel. And the shaft extension 24 of the pallet arbor 22 is similarly secured to the tube 28 which is secured to the oscillatory rider l0 shown in the form of a leg. It will be observed that in the form illustrated, the rider I i is in the plane of the dial 25, whereas the rider i8 is dis posed in front of the dial.

It is important to observe that the pallet it is of the unbalanced type containing two arms 30 and 3! flanking the tail member 32 extending away from the escape wheel. This type of pallet is now commonly employed, and is in effect a compromise over the previously used form having a counter-balancing element disposed oppositely with respect to the tail. In other words, in order to simplify the construction, this counter-balancing element is now eliminated in conventional time-pieces, the unbalance of the pallet being partially oifset by more carefully designed and balanced watch elements. In the present invention, however, the rider It} is deliberately disposed oppositely with respect to tail member 32, as clearly shown in Fig. 3, thereby serving as a counterpoise and thus eliminating the disadvantages of an unbalanced pallet. It therefore serves not only as a reciprocating animator element, but also as a counter-balancing element. And it is important to observe that this counter-balancing element is simply and conveniently mounted upon a pallet of commonplace and conventional construction except that the arbor terminals are somewhat extended. Furthermore, the said counter-balancing rider is completely clear of and remotely positioned with respect to the escape wheel H2, in contradistinction to the old form of balanced pallet where the counter-balancing component was necessarily placed close to the escape wheel.

The wheel rider ll, being directly connected to the escape whee i2, will have an intermittent rotary movement, and its motion will bear a con stant cyclic relation to that of the oscillatory rider or leg H3, inasmuch as the pallet to which the rider i0 is attached is cooperatively associated with the escape wheel.

It is of course obvious that instead of a wheel and leg, the dial can, in accordance with this invention, contain a great variety of combinations of two coactive riders, whereby innumerable coordinated animated effects may be obaxes of rotation of the pallet and escape wheel, they require a minimum of power for actuation. The circular configuration of the disc H, which is the preferred shape of the escape wheel rider, together with the counterpoised position of the pallet rider Ill, serve to permit either small or relatively large animating movements, without disturbing the normal operation of the time-piece mechanisms, even in the case of delicate watch movements.

In the modification shown in Figs. 5 to 8, the rotary element attached to the escape wheel is dispensed with, and only an oscillatory rider as is employed. This is mounted on the elongated shaft extension 35 of the pallet arbor 36 carrying the pallet 31 the pins 38 of which are engageable with the conventional escape wheel 39. The said rider 34, in the particular form thereof shown, consists of one arm 46 oppositely disposed with respect to tail 4| of the pallet 3i, and two oppositely disposed arms #32 and i3. Arm at is shaped and colored like a tongue, and is bent forwardly to extend into the opening i i representing the clowns mouth on the dial t5, the rest of rider 554 being behind the dial. The two arms C 2 and 43 have eye portions is painted thereon, these being disposed directly behind the two openings 41 in the dal.

It is apparent that the conventional oscillatory movement of the pallet will cause a corresponding movement of the rider as, thereby producthe animated effect of moving eyes and tongue of the clown depicted on the face of the dial. And this is accomplished without chang ing the conventional construction of a watch mechanism except for the single expedient of using a-pallet arbor with a somewhat extended forward shaft terminal. No undue load or unbalancing effect is imposed on the mechanism, due to the symmetrical mounting of rider 34 at the axis of the pallet 31.

In the above description, the invention has been disclosed merely by way of example and in preferred manner; but obviously many variations and modifications may be made therein which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or manner of practicing same, except insofar as such limitations are specified in the appended claims.
