22 Claims. (01. 40-10:)

This invention relates to toys, more especially a roll-over toy, and still more particularly to a running toy which .'rolls over at' intervals as it runs along. y

5 The primary object of my invention is to generally improve toys, and to provide a toy of the specified character.- A more specific object is to provide mechanism for causing the desired rollover action, which mechanism is inconspicuous 1 and does not detract from the realism of the action ofthe toy. Another-object is to so arrangethe toy that it changes direction each time-that it rolls -over. "Still another object 'is to provide a simple and inexpensive mechanism for causing intermittent action of the roll-over mechanism, thereby ail'ordingopportunity for the toy to run along 'for some distance before again rolling 'over, Still another object isto embody the toy in the formof Ydog which simulatedly runs along, rolls over and'again runs along and, rolls over until the motor is unwound, the reaction memberforcausing therollingofthedogbeing so designed as to simulate the tail of the i108;

. Another object of my invention is to embody the toy in the form of an airplane which simulatedly performs a barrel roll, preferably accompanied by a sharp changein direction. Inns? much as the wingsproje'ct from the fuselage for;

a substantial distance at the forward end, com-'.

pared. to the tailat the rear end, .the desired change in direction is readily obtained during the barrel roll. However, thesaid wing spread also makes it diihcult for the airplane to roll over,

- and an ancillary object of my invention is tofa cilitate this rolling over:-ofthe airplane, and "for this purpose, I provide substantial projections-at the top and bottom of the'fuselage;

A more specific object of the invention is 'to j provide a reaction member which bearson the V 4 floor for a substantial distance; For'thispurpose, the end is the reaction member is' preferably bent forwardlylat a point far enough-from the body to rotatively clear the same, and the angle at which it is bent forward is made such 45' that it rests flat on the floor when it is rolling thetoyover. e Still another objector the invention is'to provide means for holding" the reaction member oi! the floor when the toy is running forward. This 1 50 refinement-is not essential, but it is desirable in order to prevent the reaction member from impeding the progress of the toyif the toy is operated on a thick carpet or a rough surface. For

this purpose, the drive. between the motor and 55 the reaction member is made intermittent by.

invention consists in the toy elements and their relation one to the other, as hereinafter are more particularly? described in the specification, and sought to be defined in the claims. The speciflca- 10 tion is accompanied by drawings in which:

The invention is disclosed in three iorm's. In

-.thev first form, the roll-over toy simulates-a dog,

vand this form of the invention is shownin Figs.

1 through 4 of the drawings. In the second form, 40 e the toy simulates an'airplane, and this form of the invention is illustrated-in FigsI 5 through 9 of the'drawings. In the 'third--form, the toy also.

eliminates an. airplane, this being illustrated in- 'Flge.1o,.1l and'12 oi'thedrawinss.

Referring to the am rel-m of the invention,

' and more. particularly to Fig, 1, the toy comprises 8' preferably elongated fbody I! provided with preferably inconspicuous. and nearly concealed wheels M aim-u. A'reaction member I8 is disposedalong'side the toy and-is-comiected to the shaft ll which extends longitudinally of the toy and projects iromtherear end thereof. In the present case,'the reaction member l8 and shaft 20 are made by bending a single continuous piece s Referring now to Figs. 2 and 3, the toy is provided with concealed motor works generally designated 22. This includes a spring motor which isof conventional character, in that it comprises a square winding stem 24 and a spiral ribbon spring 28, the outer end 28 of the spring being connected to the motor frame and the inner end being" connected to the winding stem 24. The motor is provided with a'train of step-up gearing fordriving the rear wheels l4. Specifically, the winding stem 24 carries a main gear 30 meshing with apinion 32, which is secured to an intermediate gear 34, -which in turn meshes with a pinion 38 carried by the axle 38 of wheels i4.

-The wheels are, of course, secured to the axle and rotated thereby.

The motor may be wound by a key 48 which may be applied to one end of winding stem 24 through an appropriate hole in the side of the my body. The motor may, of course, include the usual ratchet or clutch mechanism to permit winding the spring without driving the gears and wheels. If desired, the motor may be provided with a speed limiting device or governor which, in the present case, comprises a weight 42 carried on an arm 44 which is oscillatable about the axle 38. Axle 38 carries a gear 48 meshing with a pinion 48, said pinion carrying an eccentric 5B, which-eccentric is received in a mating slot in arm 44. It will beevident that as the motor unwinds the weight 42 is reciprocated at very high speed by the eccentric 58, and this limits the unwinding speed of the motor.

The motor is provided with another gear train leading to the shaft 20. More specifically, the winding stem 24 carries a mutilated gear 52. This meshes with an idler pinion 55, which in turn meshes with a crown gear 58, the latter being secured to the inner end of shaft 20. It-will be evident that during unwinding of the motor,

the shaft 20 is rotated, but at a speed much slower than the speed of the driving wheels. M. Moreover, the rotation of shaft 28 is intermittent, for

the shaft dwells when the mutilated parts 58 of 7 gear 52 reach the pinion 54. The number of teeth left on mutilated gear 52 is preferably so selected as to produce one complete revolution, or a little less than one complete revolution of shaft 20, thus bringing the toy from upright posifion back to upright position again. Inthepresent case, the teeth have been divided into two parts, so that there is a dwell during the rolling over of the toy. However, the teeth may be combined so as to produce one continuous rolling over -of the toy, or on the other hand, the size of the gear and the number of teeth in each porappropriate tongue connections passingthroughwashers, this being indicated at B8. The bottom of the toy is closed by a bottom plate 82, this being secured to the sides by conventional tongue and slot connections as -is indicated at 64. The front wheel I8 turns on a pin 86 which is carried bylugs 68 bent upwardly from the bottom 82 of the toy. The motor 22 includes a frame which is .desirable.

rolling over more than a full revolution, or from -secured to the bottom plate 62 by appropriate tongue and slot connections 10. The bottom plate 62 is, of course, cut away as is indicated at I2 to clear the driving wheels l4. .A part of the bottom has been broken away beneath the-motor in Fig. 3, in order to expose the parts of the motor. The shaft 28 is carried at its inner end by the motor frame, and is additionally carried by a small bearing plate 14, which may also be used as a connector plate or washer for securing the halves of the body together.

It may be pointed out that the body is larger in dimension at one end than at the other. Specifically, in the present case, the vertical dimension of the body at the top of the head or at the point 16 (Fig. 1) is substantially greater than at the rear end of the body, say, at the point 18. This causes the toy to change direction each time it rolls over as is hereinafter described.

The operation of the toy will be clear from ex-- amination of Fig. 4. Thetoy may be assumed to be initially running in the direction 80. The tall or reaction member 3 rests loosely on the floor as the toy runs along. At this time, no rotative force'is applied to the member [8. When the toy reaches the position 82, it begins to roll over, this being caused by the fact that a toothed part of the mutilated gear has come into mesh, thereby applying a rotative force to member l8. -The direction of this rotative force is such as to tend to force member l8 downwardly, but inasmuch as it is already resting on the floor, the toy instead rolls over on one side, as is indicated at 84. It continues to roll over to an upside down position (not shown), and rolls further to a position on the opposite side, as is indicated at 88. If

the mutilated gear iscut away at this point, theside for a time in the position 86. When the teeth of the mutilated gear again come into action, the

toy is rolled further, and finally comesagain to the upright position indicated at 88. During the rolling operation, the driving wheels I4 are rotating, butno forward movement of the toy takes place, for the wheels are not on the ground. On reaching the position 88, however, the driving wheels are again on the ground and the toy runs forwardly, as is indicated by the line 90. At this time no torque is applied to the reaction member II, for a toothless part of the mutilated gear has again been reached. The toy runs along to the position 92, at which time a toothed part of the mutilated gear is again reached and the toy again rolls over, as is indicated by the successive'positions 94, 88, 98. wardly, as is indicated at It"), and when a toothed part of the mutilated gear is again reached, the toy again rolls over, as is indicated by the successive positions I82, I84, I06, I08.-

It will be observedthat because of the configuration of the toy body, the direction lines 88, 80 and Hill are'angularly related to one another, so that the toy in the course of its continuous operation may describe a complete circle, and thus be operating within the confines of a single room.

Reverting to Figs. 1, 2 and 3 attention may be directed to the stud H0 projecting from the bottom of the-toy near one edge, specifically, the edge opposite the reaction member l8. This stud is not essential, but in some cases may prove Its object is to prevent the toy from The toy then again runs forcontinuing its rolling action past upright posi- 7g tion under its own inertia. In the present case, the toy has only three wheels and the two rear wheels are rather close together. The toy, therefore, rests somewhat imstably on the three wheels, and if the turning force bringing the toy to uprightposition is great, the toy may continue rolling past the desired upright position. The stud IIIl adds stability to the toy and makes it more diflicult for the toy to accidentally roll 10 past the desired upright position. I

Referring now to Figs. 5 through 9 of the drawings, the toy. there shown simulates an airplane comprising a fuselage II2 with a pair of wings Ill projecting sidewardly therefrom. The fuselage runs on-main driving wheels H6 and a tail wheel H8. The wheels II6 are carried in a motor frame I which preferably projects a substantial distance beneath the fuselage. The rear end of the fuselage is pro- 20 vided with a tail I22 and an upstanding surface l2l'simulating a rudder. A further projection I26 'is provided at the top of the fuselage to facilitate rolling over of the airplane despite the sidewardlyextending wings III. In the present the projection I28 simulates the head of a p at. g 1 v The reaction member is indicated at I33. This consists .of a single piece of wire, the inner end I32 of which is rotatably'mounted inthe airplane and extends in. the direction'of the axis of'the fuselage. The wireis bent sidewardly at I34 an amount sufficient toclear the tail I22 and the rudder I23 offthe airplane. The part I 33 is bent forwardly and is disposed in sucha direc as tion that it normally rests flat on the "floor or surface, or in other words, the floor over its entire length when it isoperat ing to roll the airplane over. The desired angle maybe determined by experiment, but as a rough guide, it may be-said that the part .l33 should extend approximately in the direction of thetip of wing ill. Assbefore, the wheels 6' are preferably driven continuously, while the reaction member I3! is driven only intermittently. Referring-to Fig. 6, the motor comprises a prefer ablysquare winding stem I36 about which is wound a conventional main spring l33. This in turn drives a. mutilated gear I the teeth of which mesh with a pinion I42,\which inturn drives a gear I meshing with -a pinion I46 mounted directly on the axle I43 which carries the wheels I I8.- If desired, the unwinding speed of the motor may be by suitable governor mechanism such as an escapement plate IUII oscillated'by-the teeth of an escapement wheel I82 moimted on axle "8.x g j A separategear train is provided for the reaction member. This includes the mutilated main gear Ill'meshing with an idler or inter .60

mediate pinion. I54 which-in turn meshes with acrown gear I secured tothe'inner'end of the shaft or wire I32 carrying the reaction member. The pinion "(is comparatively short,'and isso located that a. part of gear I 40, namely thepart 65 J53, meshes-with pinion In, whereas another .part, namely the part I60, clears the end of pinion I and does not drive the same. In this respect the comparatively short pinion Illisto be contrasted with the longpinion I42 in. the gear train leading to axle M8, for either of the parts III or I60 meshes with the long pinion I42, hence the drive of the axle is continuous.

The construction of mutilated' 'gear fl" may be furtherexplained with reference to Figs '7 and '8, in which it will lie-seen that the gear comaose 3 prises adisc of sheet metal I62, a. part of the periphery of which is 'drawn or displaced sidewardly. Both the flat and displaced parts of the gear are cut to provide a, continuous series of gear teeth, as will appear from inspection of Fig. 'I, but some of these teeth aredisplaced sidew'ardly, as at I58 in Fig 8, while others are not, as at I60. It happens that in the specific form here shown, there are two displaced sections corresponding to two running periods and two rolling-over periods, for each complete revolution of the winding stem I36. However, the operating principle is, of coursathe same as if there were only one ac d section.

Referring now to Fig. 9, the toy runs forward, as is indicated by the. line I64, untilthe teeth I58 of the mutilatedg'ear comeinto actio at which time the reaction member I30 bears downwardly against the floorand causes the airplane to roll over, as is indicated by the successive positions I86, I63, I10, I12 and I'll, at which time the airplane is again right side up on its running wheels. While rolling over, the toy has changed substantially in direction, and in the specific case here shown, the airplane next runs in the direction of line I'IO, which is approximately at right angles to the original direction line I. The. toy'pr 7 along the line, I'Ii until the s dewardly ced teeth III of the mutilated gear 1 againlcome into mesh with the idler pinion I, El-ii which-time the airplane is again oausedto' ro'i pyergthisbeing indicatedjby the successive pos --t ions-; m, I33 I32. The number. of teeth. inthelinutilated gear is."'of course, so selected as to bring {the-airplane ba'clr to. upright position on its -mnnlngjwheels, whereupon the toy again forward in the" new direction; as is indicated the direction lihe Ill. Anotherform of toy airplane is illirstratedin Fig. 10 In this case the airplane simulates a modem" airplane with an enclosed cabin Isa. If this cabin does not provide suiiicient projection above the fuselage to facilitate rolling over of the airplane, the airplane-may 'beprovided with an arcuatelybent,piece of wire I83 extending substantially from wing tip to W tip. This wire is'not sis-conspicuous it appears in Fig. 10,, because when looking a the toy'from any other directlon, thewings I'll have broad, extensive surfaces, whereas The airplane of Fig. '10 illustratesa much more important feature, which feature is applir'zahle to-all formsof-roll-over toy including, for ,ex-.-

ample. the animal or dog toy first described; I am referring to the fact that the reaction mem her I92 does not rest-on the floor or running surface Ill when the toygislrunning forward on its wheels I". Instead, thereaction member I92 issupported above the floor and in no 'way impedes the progress of the toy.

.Qnepreferred way in which this maybe done is described with reference to Figs. 11 and 12 of ;the drawings. which are ctively side and end elevations of the motor used in the airplane.

of -Fig. 10.- This the axle 2" of wheelsjlfl; Specifically. ear 208 meshes with a. pinion 2I2 which is secured to a gear 2M meshing with. apinion 2N mounted directly on axle 2Il.- IfdesIred the'speed of the member I83 is a mere wire.

motor comprises a main windas ing stem 203 carryinga conventionairibbon orv of whichissecuredtotheframe 28$ ofthe mo r. I The main stem 23! carries a gear 203 for driving 7 the motor may be iimitcd'by suitable governor is l already described in connection with Figs. 2 and 3. Specifically, it consists .of a gear 2I8 on axle 2l 0,-meshing with a pinion 220, which in 5 turn rotates an eccentric 222 riding within a slot 224.cut through an oscillatable member 226 which in the present case is pivoted for free oscillation on axle 2I0.

A completely separate geartrain is provided for intermittently rotating the reaction member I92. Specifically, the winding stem 200 carries a crown gear 230 (Fig. 11) which meshes with a pinion 232. Pinion 232 is carried on a shaft 234 extending longitudinally of the toy, and in the 15 present case, just outside the side plate of the motor frame. The side plate is cut away at 236 to provide access between crown gear 239 within the frame, and gear 232 much of which is outside the'frame. I

At its rear end the shaft 234 carries a mutilated gear 238. This meshes with a pinion 24!! mounted at the inner end of a shaft 242 which extends longitudinally of the fuselage and pro-' jects rearwardly therefrom. Actually, the shaft 25 242 and the reaction member I92 may consist of a single piece of wire appropriately bent, but functionally, it may be said that reaction member- I92 at the side of the toy is connected to shaft 242 carrying the pinion 240.

Mutilated gear 238 has enough teeth to produce one revolution of the reaction member. The remainder of mutilated gear 238 is devoid of teeth and this mutilated part of the gear corresponds to a dwell period for the reaction member. It is very important to. note, however, that in the present case the teeth are not cut away to their full root depth. Instead, the portion 244 is made of such radius that it bears against two of theteeth of pinion 249, as shown in the drawings, and

prevents rotation of the pinion. The action is equivalent, to that used in typical Geneva gear mechanism or transfer mechanism for counters and the like, in that driving gear 238 produces only intermittent movement of the driven pinion 240, and between movements, the pinion 249 is locked against movement by the gear 238. Of course, the fullroot depth is used at the ends of the portion 244, as is indicated at 246, for otherwise the gears would lock at that point It isobvious that by properly rotatively relating the reaction member I92 to the pinion 240, the locked position of the pinion may be made to correspond to the desired elevated position of the reaction member, 'so that 'the reaction memher is heldoff the floor, as illustrated in Fig. 10.

Moreover, the reaction member may be held somewhat higher, as when simulating the tail of an animal, but, of course, it must be brought down far enough to successfully complete the rolling go over of the toy onto its running wheels. The exact point at which the movement of the reaction member may be stopped depends on the configuration and balance of the particular toy, for.

the last .part of the movement of the toy onto its .5 wheels 'will takeplace automatically after the toy has been moved to nearly upright position.

It is believed that the construction and operation, as well as the advantages of-my improved .toy, will be apparent from the foregoing detailed to description thereof. It will also be apparent that while I have shown and described my inventionv in several preferred, forms, many changes and -'modiilcations.may be made in the structures disclosed, without departing from the spirit of the 7| invention defined in the following claims.
