This invention relates to skipping toys and has for its object to construct a mechanical'toy in the form of a doll or other figure which, when in operation, will maintain itself in an upright or other desired position and will simulate in a realistic manner the action of skipping.

The toy may in some cases be constructed to travel bodily while in operation, in other cases the travelling motion may be eliminated.

p The invention consists of a mechanical doll or other figure having combined there with a device to represent a skipping rope, means to maintain the doll or figure in an upright or other position while in operation, means to impart rotary or oscillating movement to the. skipping rope device whereby the action of "skipping is automatically simulated, and with or without means to cause or enable the toy to travel bodily.

It is also a feature of the invention that the toy may be constructed in such a manner that the doll orfigure will operate with. a vertical motion to simulate the action of jumping, which motion, combined withthe rotation or oscillation of the rope device produces life-like effects.

In some cases the skipping rope device consists of a complete loop over which the doll or figure rides; or jumps. In other cases the rope device may have a gap in it to pass the base of the toy.

The toy is self-supporting, on its own base and for the purpose of maintaining it in an upright or other position, gravity, gyroscopic or other means such as a three or four point contact support may be adopted.

The toy may be caused to travel by grav ity or it may be drivenby a suitable motor such as a gyroscopic or momentulnwheel, spring' or clockwork, electric or other means, W hen the toy is mechanically propelled motion may be transmitted to a supporting wheel or wheels or the'action of the skipping rope device may be utilized to impart the travelling movement.

The necessary motion for rotating or oscillating the skipping rope device may be derived from the travelling or driving means either directly or indirectly or the said device may be motor driven and drive the t avelling means. When the doll or figure is given a vertical movement to simu- 58'5,264, and in England" November 23, 192-1.

late jumping, thismovement may be utilized to rotate or oscillate the rope device, or vice versa'.

The invention is mainly, though not ex clusively, applicable where the frame or body of the toy is found to represent a doll, animal or'some similar figure. While the principal object is to actuate a member representing a skipping rope other parts may be actuated such for example as a sun shade or walking stick or one or more parts as the head and arms of the figure may be given an oscillating reciprocating: move ment.

To enable this invention to be more clearly understood, reference will he made in the following further description to the accompanying drawings, wherein:'

Throughout the drawings like parts are designated by the same reference characters in the several figures where they appear.

According to one manner of carrying out the invention a rotary element suitably mounted in or on the frame or body of the toy is driven by or from a momentum wheel or its spindle in such a manner that it runs at a slower speed than said wheel. This element isused to actuate the movable part of the figure.

For instance, the body or frame of the toy may carry a horizontal rotary spindle which extends through the arms of the doll and has attached to its outer extremities the ends of a U shaped Wire or equivalent member the bow of which is large enough to pass under the supporting wheel of the toy when the spindle is rotated. Rotation may be imparted to thespindle by friction gear, bevel gear, worm gear or other suitablemeans from the spindle of the gyroscopic wheel or a driving member thereon.

In a practical form of this subject matter the upper end of the gyroscopic spindle 1 is furnished with a capstan 2 or the like which drives a friction disc 3 mounted on the horizontal spindle 4:, said friction disc being pressed into side contact with the capstan 2 by a light spring 3 or alternatively the capstan may be magnetized to maintain driving contact with the disc. According to another arrangement the momentum wheel 5 is mounted to rotate upon a sleeve 6 by means of ball bearings as shown in Figure 20. The sleeve may be rotatable upon a fixed vertical rod or spindle 7 or it may be I fixedand form a bearing for the said spindle and a boss 8 on :the gyro-wheel forms a ball .race for the said ball bearings. The verticalrod or spindle 7 may constitute the central part of the frame '8. In :the event otthe sleeve being rotatable it may at its upper end drive thediscB on the horizontal spindle 4L and at its lower end be suitably formed to .drive the supporting wheel :10. The :momentum .or .gyro wheel may be i disposed either horizontally as in Figure .1 or vertically as in Figure 3 in which latter case rotary movement is imparted to the spindle 4 by means :of two small friction wheels llsituated on the gyro-wheel spindle l which frictionally drive :the wheels 12, bosses on which latter drive the balanced wheels =13-which are securely fastened to'the horizontal rod or spindle 4.

The Ushaped wire 14: representing a skipping ropemay be couuterweighted in. suitable .manner (15, .FigureS) to balance itand ifacilitaterotation thereof. To fa cilitate passage of the carrying wheel '10 over the rope when travelling on a flat surf-ace a cord 16 or-similar section maybe inserted at the central part thereof. A-sniall section may be cut=out "of the bow s centre it desired'when the toy is to travel on a wire or rail.

Where an oscillating or reciprocating movement of some'part of the body or frame is required, the disc 3 orwheel driven by thespin dle or sleeve of the momentum wheel 5, may actuate a crank, eccentric, cam or equivalent device as will be hereinafter described.

To facilitate'the travel and mounting of the'toy over the shipping rope, the carrying wheel 10 may'have a serrated, fluted or roughened periphery.as shown in Figures 6, 8 and 9 or it may havea rubber tireand when the gyroscopic spindle or sleeve is 1nagnetized as before mentioned, in order to obtain an eflicient drive of the supporting wheel, the lower end of the spindle or sleeve is made conical and is'disposed centrally and points downwards in .a V groove in the wheel so aszto rest upon both inside edges or flanges of thehatter (Figures 5, ('3, 7'and 8) one "side of the wheel being made of magnetic and'the other side of non-magnetic oranti-friction material. I

In a convenient constructional fornn'the supporting wheel 10 is made in halves one side 10 being iron while the opposite 10 is brass. The two halves are secured together by rivets or in any other suitable manner. The angle of. the conical end of the spindle 1 is greater than that of the V groove of the wheel to ensure contactwith the latter lat the-top inside of the groove only.

In one. embodiment of this subject matter the skipping :and jumping mechanism is driven -by:a spring motor and agyroscopic wheel iswound up and rotated-by string. In another embodiment the skipping and jumping:mechanism maybe driven througha suitable reducing gear froin'thegyroscopic wheel. Or alternatively a spring motor'may actuate both the shipping and jumping ,niechanism and the gyroscopic wheel. 7

The jumping mechanism 2 embodies :a spring attached at one end to't-he-supporting member of the toy and at the other end to a part capable of movement in re lation .to said member, and driven 'z'means which first gradually move said :part :relatiiielyito the IRGIfllJGI'LbO' compresstthe spring and then suddenly release saidpart whereupon the spring becomes active .and moves said part in the reverse direction untilion reachingthe limits of its reco'il or uponthe movement of the part beingarrestediby thesupporting member, the latter is lifted bodily.

The impetus imparted in an :upward direction to the betorementioned part byithe recoil of the spring issuflicient when'suddenly transferredto the suppOrting mei'nber to cause tne toy "to :jump upwardsifroinzth-e surface uponwhich it has been pla'ced.

Preferably-the-said part carries the moinentum wheel and body or frame ot the toy, and 1 the supporting member consists ot' a central vertical rod or spindleuponwhieh tlie part slides. l'llhedriven means-Tor nioving andreleasing the slid-able part may consist of'a lOlZRIYCMD or mutilated gear wheel operating in contact with a roller-or teeth onthe supporting member said cam or'gear wheel being rotatedin-unison with the skipping rope -so "that simultaneously with the upward jump otthe'toy the rope will pass under the lower extremity :ofthe supporting member.

convenient constructional form of this su'bjectmatter is shown in Figures 20, 21 and 22. The mainbody or fr'ame 9 of the toy has fixed on the lower part thereof a sleeve '6 having revolubly -mounted .on the exterior thereof ('pre'ferablyby'ball bearings, Figure 20) a freelyrotatable'momentum wheel 5 the casing'or covering 17 "of which may resemble the whole or part of the skirt of the figure. The sleeve 6 is slidable up anddown'upon 'acentral=vertical rod 7 which at its lower e-Xtremity'is formeol or provided with a foot or feet 18 upon which the toy is to stand. Situated between acollav. or flange 6 on the lower end of the sleeve 6 and a collar or dance 19 near the lower end oft-he central rod is a'compressionspring 20having its opposite ends suitably attached to the respective collars or flanges. The upper end of the central rod 7 projects into the hollow part of the body and is securely fastened to a frame 21 which latter carries a roller 22 with which the periphery of a snail cam 23 attached to a horizontal spindle l engages. This spindle passes right through the body and extended arms of the figure and carries the skipping rope? 14 as hereinbefore described, the bow of said rope being large enough to pass under the feed of the doll.

The spindle is driven by suitable gearing actuated by a spring motor 24 of the usual clockwork type fixed within the body. Rotation of the spindle causes the skipping rope to revolve and the cam 23 on said spindle by acting against or under the roller 22 depresses the sleeve 6 and body 9 against the spring 20 until the nose of the cam passes the roller whereupon the sleeve is moved upwards on the central rod 7 The upward movement of the sleeve on the rod may be limited by the spring or by a collar or shoulder 7 on the rod.

To prevent the spindle racing after release of the cam from the roller a suitable brake or resistance device 15* may be provided.

An alternative construction is shown in Figure 22 in which the momentum wheel 5 is driven by the spring motor, and the lower end or base of the frame'orbody 9 acts as a collar orshoulder in place of the flange 6 of the sleeve 6 as shown in Figure 22. The frame21 carrying the roller 22 is fastened directly to the feet 18 thus eliminating the central rod 7 and the body rises and falls with the gyro-wheel and spindle 1.

In another form of the improvedtoy the doll or figure is mounted to run on a pair of wheels 25 and 26 arranged side by side on a suitable axis 27. to afford lateral support,- the figure being maintained upright by a weight28 disposed below the axis of the wheels. a

A horizontal shaft 4 running through the arms of the doll carries the skippingirope as-hereinbefore described, said shaft being rotated either by a momentum or gyro-wheel 5 by a spring motor 24, or from the supporting wheels 25 and 26 by means of gravity,- and may be driven either by a train of gears or by an elastic band running round pulleys, said means being conveniently housed within the body or frame 9 of the iln another form of the invention the doll or figure is mounted upon two pairs of wheels arranged one behind the other the wheels in each pair being spaced apart to give lateral stability to the toy. The wheels thus support the doll or figure on a four pointcontact, The axles of the running wheels are driven by a gear wheel meshing with pinions thereon the said gear wheel being actuated by a spring or other motor conveniently applied.

Instead of using two pairs of running wneels, one pair of'wheels 25 and 26 laterally spaced apart may be used in combination with a single wheel disposed in front or rear of said pair and providing a three point contact, or we may use a pair of wheels 25 and 26 side by side spaced apart to give lateral stability and a pair of wheels 29 and 30 in alignment with each otherbetween the first pair to give stability in a forward and backwarddirection on the principle of a four point contact.

In, this latter form the two wheels 29 and 30 may be so disposed that they both just clear the floor as shown in Figures 30 and 32. V I

In traveling the front wheel 29 rides on the floor while the back wheel 30 rides free. Upon the ropereaching the wheel 29 it pases under same, and tilts the figure backwards on to the wheel 30, and the reverse operation occurs upon the rope passing under the back wheel 30, thus imparting to the figure aswaying or rocking motion during operation.

The doll or figure may have an up and down movement imparted to its nether limbs to simulate the action of running or walking. In order to bring this into effect the main wheels 25 and 26, which are preferably serrated or grooved, are fitted with eccentric pins 81 upon which the feet 18 of the figure are loosely mounted, the other or upper end of the leg being mounted 'upon a cranked horizontal shaft 32 geared to the skipping rope spindle 4. The cranks'may be arranged to operate the legs and feet simultaneously as in Figure 34L or alternately as in Figure 33, and the smaller wheels 29 and 30 may be mounted on springs 32 as shown in Figure in order to facilitate the passing of the skipping rope thereunder.

' The doll may be driven by a spring or electric motorby means of a momentum or gyro-wheel, by gravity, or it-may be driven intermittently by neans of the skipping rope. For instance, in the forms shown. in

Figs. 10, 11 and 12, travelling movement is imparted to the doll by the skippingrope device which is driven by a clockwor r tor and makes contact with the ground at each revolution. To'increase the propelling effect of the 'skipping'rope device beads 39 may be inserted thereon. for making contact with the ground, said beads being preferably made of rubber or the like.

In cases where the bow or like device representing-the skipping rope passes underneath the running wheels of the toy it may be furnishedat the extremity of the bow with an inserted section of rubber, cord, or

some other suitable material 16 which will facilitate the passage of the wheels thereover.

In cases where the supporting wheels are grooved to run along a cord or wire the skipping rope is cut open at the bow to form a gap to pass said supporting wheels.

The carrying wheels may be driven by gears from the motor or the like or by means of a connectin rod 40 as shown in Figures 2629.

As previously mentioned herein, the rota tion of the rope device may be utilized to impart a vertical movement to the doll to simulate jumping. This is readily effected by making the rope device long enough to strike the ground so that its impact lifts the doll bodily. In such case, the rope device may be made either with stiff sides or in the form of a. complete wire bow, such as that shown in Fig. 33 and while in this view, the rope device is shown operated by gravity actuated gearing, yet it is within the purview of the invention to substitute a motor driven gearing for the said gravity actuated gearing, a. small amount of clearance being provided between the inside of the wire bow and the wheels upon which the doll stands. The wheels, may, however, be omitted in which case the doll stands upon its own feet in the same manner as'the forms shown in Figs. 20 and 22. i

The skipping rope device. during rotation, strikes the ground just in front of the dolls feet, its impact with the surface. upon which the doll stands lifting the doll so that the skipping rope device passes thereunder. The doll is thus caused to ump over the loop and the contact of the latter with the ground impels the doll forward. As during operation, the doll maintains its own equilibrium and stands upon its own foot base, the result is that the action of skipping is simulated in a realistic manner. The foot base upon which the doll stands, whether provided with wheels or not, is preferably formed to provide a four point contact with the ground.

lVhile I have described in the foregoing specification the construction of parts and operation preferred, I am aware that numerous changes of construction and operation may be made without departing from the spirit and scope of the invention, and I therefore do not wish it to be understood as limiting myself by the positive terms em: ployed in connection with the description excepting such as the state of the art may require.
