'Ihe surface of the sphere 8 is colored in various designs, preferably of contrasting colors, to give interesting changing color eects while the top is spinning. I prefer to use the color design here illust-rated wherein the three primary colors, blue, red and yellow are employed. The surface of the sphere is divided into six equal lunes I1, the boundary circles of which intersect at common points located in the horizontal axis o-f rotation of the sphere. These lunes are colored successively, blue, red and yellow, so that diametrically opposite lunes will be of like color. A black circular area I8 surrounds each bearing center, its diameter being approximately one third the diameter of the sphere. The purpose of the black areas is to prevent mixing of other colors in the center color band, as the moment when any pair of like colored lunes occupy the horizontal, or equitorial position, which is the position in which the red lunes are shown in the drawing. n

The hollow sphere 8 is here shown formed of sheet metal. A at circular chamber |9 also formed of sheet metal, is centrally located within the sphere and is supported by the flat tubular extensions 29, which are fitted into two diametrically opposite openings 2| in the sphere Wall. These tubular extensions form air ducts, permitting air to enter the chamber I9 when in the position shown in the drawing. Musical reeds 22, similar to harmonica reeds, and preferably of differing pitch, are spaced equally about one wall of the chamber I9 and riveted thereto. Corresponding slots 23, inthe wall opposite each reed, permit passage of air around the reeds from the chamber I9 into the sphere 8. Perforations 24 in the sphere wall are located preferably near the axis of rotation of the sphere. l

When the top is spinning rapidly the air within the sphere spins with it and the centrifugal force of this rapidly rotating air body creates an air pressure within the sphere and directed outwardly from the spinning axis. This air pressure increases at increasing distances from the spinning axis, being slightly less than' atmospheric pressure at the spinning axis, and greatest at the greatest distance from the spinning axis. As the top spins the sphere is rotated about its horizontal axis at a comparatively slow rate of speed by the means already described. At the moment the sphere assumes the position shown in the drawing, air will escape through the perforations 24 and the partial vacuum thus created within the sphere will cause a circulation of air,

' entering the openings 2| and passing inwardly through the air ducts 20 into the chamber I9, out of the chamber through the slots 23 into the sphere, and out of the sphere through the perforations 24. The air, inpassing through the slots 23 will cause the reeds 22 to vibrate, thus producing musical tones. Air will continue to i circulate in this manner until, as the sphere 8` rotates about its horizontal axis, the air circulation will gradually decrease as the openings 2| approach a near horizontal position, in which position the air circulation will cease, due to the fact that the centrifugal force of the air outwardly at the openings 2| equals and balances the centrifugal force of the air at the perforations 24, both being equally distant fromr the spinning axis. As the sphere continuesto rotate and the'distance of the openings 2| fromv the spinning axis diminishes, air will begin to circulate as before and sound will again be produced and will gradually increase in loudness until the openings 2| again occupy the vertical positions shown in the drawing, when the sound will then reach a maximum.

It is apparent that the effect of this construction is to cause the top while spinning to emit sounds or musical tones periodically, the sound rising and falling, from zero to a maximum and down again, twice for each revolution of the sphere about its horizontal axis. It is also obvious that, instead of the harmonica type of sounding means here shown, any other suitable type of air actuated sounding means may be employed, as for instance the common toy horn type of sounding reed, or a whistle type sounder which requires no reed.

It is also pointed out that the air actuated sounder need not necessarily be located close to the center of the sphere but may be located at any convenient place in the air circulation system where the air stream is sufficiently concentrated to actuate the sounder. A position near the center of the sphere is advantageous, when a reed is employed as the sounding means, because there the centrifugal force is a minimum at all times and the vibration of the reed will not be affected by stresses. due to centrifugal force of the reed itself. This construction is also desirable for cheapness of manufacture and assembling of parts when a plurality of sounding reeds are employed.

While the construction and location of the sounding means described in the foregoing has the advantages pointed out, the invention is not limited to that construction. Both the chamber I9 and air ducts 20 may be dispensed with if desired and still retain the periodic sounding feature of the invention. Eliminating these members, but retaining the openings 2| and perforations 24, it is obvious that, when the top is spinning, there will be air circulation passing out of the sp-here through the perforations 24 and into the sphere through the openings 2|, and this air circulation will increase and diminish in the manner described in the foregoing. If then an air actuated sounder of any suitable type is placed, preferably inside the sphere, adjacent to either orifice and so positioned that air passing through the orifice must pass through the sounder, periodic sounds will be produced as the top spins. An example of such construction is illustrated in Fig. 5, which is a sectional View of a sounder located close to the opening 2|', which opening in this case is a round hole adapted to fit snugly the outer end of the tube 54. 'Ihe sounder here shown is the common toy horn type and is fitted tightly within the tube 54. In this position the reed 56 will be caused to vibrate and sound will be produced when the air current passes inwardly through it from outside and into the sphere. Likewise the same sounder could be placed opposite a perforation 24 in which position the bird bill member 55 would be reversed in reference to the sphere wall, so that it would be in proper position to beactuated by air passing through it outwardly. Y

Referring again to Figs. 1 and 2, any suitable form of spinning means may be provided for initially rotating the spinning member For example, the spinning means may be carried by and extend upwardly from the upper portion of the ring 5, and may comprise a centrally located pin 25 riveted to and extending upwardly from (vii) the ring 5. A spool shaped wooden handle 26 is mounted to turn freely on the pin 25 and a coiled spring 21 fits freely in a center hole in the handle 26, its upper end being fastened against turning within the spool at 28. The lower end of the coiled spring 21 is bent to form a hook 29 which is adapted to catch into a hole 30 in the sheet metal plate 3I. This plate 3| is circular in contour and is perforated at the center to fit over the pin 25 and its periphery is flanged downwardly to provide a support by means of which it is rigidly attached to the ring in any suitable manner. The plate 3| is also provided with a depression 32 positioned to receive the lower end of a catch pin 33. This depression 32 is formed with a beveled bottom to function as a ratchet notch while the pin 33 functions as a pawl. When the pin 33 enters the depression 32 it prevents rotation of the handle 26 about the pin 25 in one direction but will ride out and permit rotation of the handle in the opposite direction. This ratchet action is designed to permit rotation of the handle in the direction which will cause the hook 29 to catch in the hole 30. The catch pin 33 is guided for Vertical movement in a hole in the handle 26, and is provided with a head 34 which serves to' linut its downward movement, the pin being normally held down by the spring 35, which bears against the head 34.

To spin the top, the body portion, preferably the spinning member I, is grasped by one hand and the spinner handle 26 is rotated by the other hand in the direction permitted by the ratchet catch, the hook 29 catching in the hole 3l) prevents rotation of the lower end of the spring 21, resulting in winding the spring about the pin 25 until the winding limit of the spring has been reached. The spinner handle is then slowly released permitting the pin 33 to enter and catch in the depression 32. The spinner handle 26 is then moved upward on the pin 25, by holding the thumb against the head 25a of the pin 25 and pulling the handle 26 upward, which may be done conveniently by two other ngers of the same hand. This upward movement of the handle 26 retracts the lower end of the pin 33 from the depression 32, thus permitting the spring 21 to quickly unwind and in so doing, rapidly rotate the top by means of the hook which is caught in the hole 3l).r When the spring is completely unwound the hook 29 automatically releases its hold from the hole 3D and the top will continue to spin by its momentum. As here shown the spinner handle 26 is retained on the pin 25 by the head 25a. If desired the pin 25 may be made headless, in which case the handle 26 may be removed from the pin as soonV as the top starts to spin.

Figs. 3 and 4 show a modification of my invention, some parts of which are identical in form to those shown in Figs. 1 and 2. Such parts are designated by the same reference numerals as employed in Figs. 1 and 2. In the form of the invention described above, rotation of the sphere 8 is dependent on frictional contact between the elastic finger I4 and the surface of the sphere 8. The driving force so obtained is suicient, where there is very little resistance to rotation of the sphere 8, which condition applies to the form of the invention there illustrated. In the modification of the invention here illustrated, Figs. 3 and 4, the resistance to be overcome in rotating the sphere 8 is great enough to render a more positive driving means desirable. This object is attained by substituting for the finger I4, a toothed pinion 36 which meshes with a series of indentations 31 formed in the surface of the sphere 8', which indentations are evenly spaced in a circle about the sphere surface so as to form in effect a large gear carried by and rotating with the sphere. The pinion 36 may be mounted rigidly in respect to the spindle I0, or it may be mounted to have resilient connection to the spindle. The latter construction is that indicated in the drawing. The amount of this resiliency may be very slight, or it may be considerable, depending on the nature of the material used to connect the pinion 36 to the spindle I0. This construction permits the pinion 36 to yield slightly to adapt itself to any slight variations of the sphere surface, at the same time retaining the positive drive characteristlc.

To insure constant traction of the rubber tracking roller 9 against the ground, the roller 9 is so positioned by the spindle bearings I I and I2 that, in its uppermost position, the lower edge of the roller will normally project a trifle below the point 2al of the spinning member I. There is therefore, when the top is spinning, a slight flexing of the roller tread at the ground contact point I6, which flexing acts to insure continuous driving contact of the roller 9 against the ground.

The modification of my invention illustrated in Figs. 3 and 4 is provided with means for producing musical tones in a mechanical manner while the top is spinning and without the use of an air current. Its action depends on the use of a musical reed, or series of reeds, which are intermittently flexed from a normally straight position and suddenly released. The sudden release of the reed causes it to vibrate for a moment and produce its characteristic tone. The sphere 8 is adapted to rotate on the horizontal shaft 38, the shaft ends being entered and riveted in holes in the ring 5 at 39. The shaft 38 is stamped near its center at 40, to form two oppositely positioned ns or keys, which serve to retain the picker plate 4I against rotation on the shaft. A sheet metal disc 42 forms a central partition within the sphere 8 and is fixed thereto so that it rotates with the sphere in a plane at right angles to the shaft 38. The musical reeds 43 are riveted at 44 to the disc 42 and are located in a circle equidistant from the horizontal axis of rotation of the sphere, and in evenly spaced relationship to each other, with the free ends of the reeds pointing toward the shaft 38, said free ends being spaced slightly away from the face of the disc 42. The disc 42 is pierced by elongated slots 45, positioned under each reed and slightly wider than the reeds. These slots permit free vibration of the reeds without impinging against the disc 42. The picker plate 4I carries two inclined picker wings 46, each extending in like circular arcs but in opposite directions, from the leading edges 41, and sloping outwardly from the face of the disc 42. 'Ihe picker plate 4I is also provided with a hub 48 which is perforated at its center to fit loosely, but engaging with, the keyed portion 40 of the shaft 38. A coiled spring 49 encircles the shaft 38 and is adapted to exert a slight pressure at one end against the hub 48, to insure constant Contact of the leading edges 41 of the picker plate 4I, against the disc 42. The opposite end of the spring 49 bears against the collar 50 which is fixed to the shaft 38.

When the sphere 8, with its disc 42, is rotated on the shaft 38 the free ends of the reeds 43 pass successively over one of the leading edges 41 and under the other, or vice versa, depending on the direction of rotation of the disc 42. As the reed passes over a picker wing 46 the wing acts as a wedge to cause the reed to be flexed outwardly from the face of the disc 42, until the iiexed reed leaves the tip of the picker wing, when it is suddenly released and snaps toward its normal position. The resulting momentary vibration of the reed will produce the desired musical tone. To produce the most pleasing sounds it is desirable that each reed have a diS.- tinctive tone differing from all of the others. When the top is spinning the sounds produced will partly carry through the perforations 24 in the sphere, and partly through the wall of the sphere.

The coloring of the sphere 8 is the same as that shown in Figs. l and 2, described in the foregoing, and the same change color effects will be produced when the top is spinning.

The modification shown in Figs. 3 and 4 is designed to be initially rotated by means of a string. The spinning means consists of the pin 25, the spool 5| and the handle 53. 'I'he pin 25 is riveted to, and extends upwardly from, the top of the ring 5. The wood spool 5I is drilled axially to t tightly on the pin 25 and is fastened against turning by the slot 52 which extends across its lower face and lits over the top of the ring 5. The turned wood handle 53 is drilled to fit loosely on the pin 25 above the fixed spool 5|. The head 51. of the pin 25 prevents removal of the handle 53.

To spin the top, a string is iirst wound about the spool 5I, the handle 53 is then grasped by one hand and, while the top is held in a vertical position, the string is pulled away by the other hand causing the top to rotate rapidly about its vertical axis. The handle then being released, the top continues to spin by its momentum.

Obviously the two forms of spinning means illustrated in the drawing could be interchanged in respect to the two forms of the invention illustrated, or any other convenient form of spinning might be employed.

In the modified form of roller drive means shown in Fig 6, the spinning member' I carries the U shaped bearing member 58 rigidly attached thereto. Periorations in the vertical sides oi the bearing member serve as bearings for the two spindles 59 and 60. The tracking roller 6I and the pinion 52 are fixed on the spindle 59 and the gear 63 is iixed on the spindle 60. The gear 63 meshes with the pinion E2 and also with the gear 31 which is formed on the sphere surface, as shown in Figs. 3 and 4. The bearing 64, for the spindle 59, is elongated vertically to permit slight angular movement of the spindle in a vertical plane, about its other bearing 65, the fit in the bearing 65 being loose enough t permit such angular movement. This angular movement of the spindle 59 permits the tracking roller 6l to have a limited vertical movement. A ilat spring 65 is riveted at one end to the spinning member I' at S1 and its free end is positioned to exert a slight downward pressure against the projecting portion of the spindle 59 at a point adjacent to the tracking roller 6I, thereby causing constant downward pressure of the roller 6I against the ground. When a spring is employed to cause downward pressure offthe tracking roller against the ground, as in the construction just described, it is possible to use a tracking roller formed of an inelastic material such as wood or metal. The spring 65 may be dispensed with in the type of drive here illustrated, if the tracking roller 5I is made of an elastic material such as rubber, the resiliency of the rubber being depended on to maintain ground contact. In this case the bearing 54 should not be slotted since vertical motion of the roller Si is not desired.

In operation, while the top is spinning, the resultant motion of the sphere 8' obtained by the use of the drive means shown in Fig. 6 is similar to that obtained by the drive means shown in Figs. 3 and 4. Rotation of the spinning member I about its spinning axis causes the roller 5I to rotate by reason of its ground contact and the spindle 59 and pinion 52 will thereby be caused to rotate. The intermediate gear 63 transmits the rotary motion of the pinion 52 to the gear 31 of the sphere 8' and causes it to rotate in relation to the spinning member l at a speed slower than that of the spinning member.

The drive means shown in the several iigures of the drawing are designed to cause the rotary member, in the drawing the sphere or 8', to rotate on its axis at a slower rate than the spinning member rotates about the spinning axis. 'I'his invention is not however limited to such comparative speeds of these respective members. In some adaptations of the invention it may be desirable to have the movable member actuated at a speed as fast or faster than that of the spinning member. Such results can be obtained byrobvious changes in the proportions and arrangement of essential parts.

It will be understood that the details of construction herein shown and described may be varied in many respects without departing from my invention, the scope of which is indicated in the appended claims.
