Fig. 7 is a detail showing the operating mechanism used in Figs. 5 and 6.

This invention comprises a ring or its equivalent pivotally mounted on its periphery so that it may oscillate on this pivot. Inside the ring a stud or equivalent is provided to engage the inner perimeter of the ring. The stud and the pivot are movable relative to each other so that as the stud is moved away from the pivot a distance corresponding to the diameter of the ring, the ring is rotated until this position is reached by the engagement of the stud with the ring. At this point, if the stud is brought closer to the pivot the ring is freed and can move to a position where it is stopped by the stud again engaging the ring.

The ring may be provided with some form of translating device or indicator which provides momentumto the ring so that when the .studiis movedfrom theiinner to the outerpos'ition-itengages the perimeter of the ring, causing itlto rotateto the position .wherelthe stud .is separated from thepivot a distance corresponding to the diameter of thering. .Atthis pointif ,the..-stud is again returned .to thestarting position,lthe momentum-carries the ring 'forwardinQits-rotational movement=until stopped by the studin its'innerlposition. 1f, when in this position, .the stud isagain movedaway'from the pivot theiring is rotated in the reverse .fdiiection and by restoring the. stud-.at .the proper time-the momentum completes .the movement .of the .ring, that .is, a complete oscillating cycle.

.T-he ringlthusoscillates back and-forth inresponse to the outward and'inwar'd movement .of the .studrelative to .the pivot. [A convenient way of securing this movement is by. apair' o'flevers, one of -wh-ich.formsa handle. andis connected .to thestud and the other forms a finger..grip,fis pivoted .to the firstlever and supports the. pivot o'flthering. 'By moving the levers'towards'and away from each other in a step actionthe ring isoscillated once in. each directionafor each. step, that is, each cycle of -movement of the levels movesthe ring to a new position, where it remains until again moved by another cycle of movementof the levers.

An application of the invention isshown in connection with a disappearing toy whichdisappears into a box and is operated by a ring controlled by the levers sotlaat for each operation the figure'is moved out ofthe box to be moved backiagairi bythe next operation of the levers.

T In the drawings, H is the leverlcomprising'the handle 4 whichlsupportslthe stud!!! and [2 is the complementary lever pivoted to Hat l3 and operated by a "finger grip at 1'5. "I'he'lever 12 supports the pivot IQ of the ring IB and by spring i6 and stops I'l assumes a normal position relative to the lever l2 which brings the pivot l9 and the stud 2E] relatively close together Within the ring l8. When the finger grip I5 is moved towards M, the stud 291 is moved away from the pivot 19 and rides along the inner surface a of the ring 68, causing the ring to move on the pivot I9 along the are indicated by c to the position [8' where it is stopped by the opposite side of the ring engaging the stud 20. The ring is provided with an arm 2|, carrying an indicating device 22 which corresponds with the object to be oscillated. 22 may be freely rotated on 2| and weighted at 23 so that when the ring l8 moves to the position shown in Fig. 2 the indicating device 22 is rotated by the weight 23. It will be observed from Fig. 2 that the reverse movement corresponds to the movement in Fig. 1 except that the stud 20 engages the opposite side of ring l8 at b to rotate it in the opposite direction.

The operation will be understood from Fig. 3 showing the stud 2B moved away from the pivot l9 by deflecting the levers a distance corresponding to the diameter of the ring in which the arm 2| is in the vertical position. If the levers are held in this position, the device is locked and the arm 2| remains vertical, but if upon reaching this position the levers are returned to the normal position with the stop members I! in engagement, the ring continues the movement of the initial impulse as far as the stud 20 will permit.

In Fig. 4 the arrangement is modified to use a disc 24 instead of the ring I8. This disc is provided with an arcuate slot 25 located about the center which engages the stud 29. When the stud 26 engages the outer portion of the slot d the first impulse is transmitted to the arm 21 and, after passing the center, the stud then engages the inner surface e of the slot as it is moved by spring l6, thereby driving the arm for a full stroke in both directions without lost motion.

It should be understood that the ring and the stud engaging the ring are shown in diagrammatic form and would have to be constructed in a manner best suited for the work intended. Further, the ring may be made in the form of a cam to vary theimpulse transmitted thereto.

In Fig. the lever I l terminates in the handle 3| and the lever l2 terminates in the finger grip 32, the rubber band 33 holds these levers in the closed position. A vertical slot is provided in lever I l at 34 and a corresponding slot 35 is provided in lever l2 for the free vertical movement of the wire ring I8. This ring is provided with an extension 36 secured to the figure 31 located in the housing 38 and arranged so that it may pass through the aperture 39 which is normally closed by the flaps 42 and 43. A table is provided at 4| with a slot at 40 for the movement of member 36. When the figure is moved out of the box by the operation of 32, it rests on the table 4| as indicated in Fig. 6. The next movement of lever 32 oscillates the ring l8 and moves the figure 3! back into the box through the flaps 42 and 43. The position of the ring l8 and the extension 35 is indicated at 36a, Fig. '7, when the figure is on table 4|.

This mechanism is simple, low in cost and very effective for operating toys or for utility purposes.

Having thus described my invention, I claim:

A mechanical motion for converting a stepping motion into an oscillating motion comprising a ring having a pivotal support on its periphery, a first lever carrying said pivot, a stud engaging the interior of said ring, a second lever supporting said stud, pivotal means connecting said levers whereby movement of said levers on their pivotal connection moves said stud relative to the pivotal support of said ring to oscillate the ring.
