SPARKING TOY.

-.A1ip1 ication filed June 3,

The invention relates to a sparking toy and has as-an object the provisionof a'revoluble member carrying means to produce sparks adapted to be rotated by an improved form of drive. v v

' It is a further object of the invention to provide a sparking toy in which the revoluble member revolves freely, being engaged by the driving member only when driving force is being applied thereto.

It is a further object of the invention to provide a sparking toy in which the spark causing elements are brought into operative position by centrifugal force when. the revoluble member is caused to turn.

It is a further object of the invention to improve details of this class of toys.

Further. objects of the invention will appear from the. following description, when read in connection with the accompanying drawing showing an illustrative embodiment thereof, and wherein Figure 1 is a side elevation, Fig. 2 is a central vertical section on line 22 of Fig. 1, and, a Fig. 3 is a rear elevation. As shown the device comprises a, handle member 10 supporting a frame member 11 formed of parallel portions 12, 13, the lower ends of which are brought together at 14, 15 and inserted in the handle member 1O.

To carry an annular abradant surfaced material 16, a disk 17 is shown, having its edges crimped about the member 16 as at 18', and secured upon themember 13 by means of screw 19 taking into a sleeve 20 which in turn is secured to the member 12 as by means of a screw 21. Sleeve 20 serves to hold the frame members 12, 13 in properly spaced relation.

To carry the pyrophoric element supporting means 22, 23 and to revolve the pyrophoric elements 24, 25 adjacent the member 16, there is shown a revolving disk 26 carried by shaf t 27 projecting through the disk '17 and being" journaled in frame members l2. 13.

The disk 26 is shown as carrying a hub 56 provided with recesses to fit freely over projections 57 carried by shaft 27 whereby the disk is caused to revolve with the shaft. To provide for ready removal of the disk for the purpose of renewing the pyrophoric elements, the end of the shaft is shown as formed with a notch to receive a spring 58 secured to the disk as at 59. By lifting the i 1927. seri l No. 196,256.

spring 58 out of the notch the disk may freely be removed.

To drive the shaft'27, there is shown a pinion 29 rigidly fixed. to the shaft, which pinion may be driven by a gear 30 mounted upon shaft 31, which shaft also carries pinion 32 rigidly =fixed thereto. 'Drive of pin ion 32and gear 30 is provided by means of a rack'33 in the form of a sector carried by lever 34 pivoted upon a shaft- 35 in ears 36,'

37 projecting from the frame members 12, 13. The lever 34 is shown as formed with an car 38 turned at an'angle and overlying the projection 37.

To hold the lever 34 in its normally retracted position, there is shown a spring 39 anchored to'theprojection 36, coiled about the shaft 35, and having its other end an-- chored at 40 upon the lever 34.

To permit movement of the gear 30 into and out of mesh with the gear 29, the shaft 31 of the gear 30 is journaled in slots 41, 42

in the frame members.

To pivotally support the pyrophoricelement carrying members 22, 23 upon disk 26,

'said disk is formed with ears 43, 44, 45, 46,

formed from the material of the disk and turned inwardly. The ears are provided with openings into'which projections formed from the material of the members 22, 23 pro ject as shown at 47, 48. 1

To permit a display of sparks caused by the action of the pyrophoric elements against the abradant surface, the disk 26 is formed with openings 49, which are desirably covered with transparent or translucent members 51, 52 which are desirably formed of colored material. The ends of the members 22, 23 are shown as bent upwardly and projecting throughopenings 53, 54 in the disk 26. .The operation of the device is as follows: I Y

- When the thumb member 55 carried by the lever 34 is pressed upon by the user, the initial pressure causes gear 30t0 be forced into mesh with the pinion 29, the shaft 31 riding up in the slots 41, 42 with consequent revolution of the disk 26. When the disk 26 is thus set into revolution, centrifugal force tending to cause the members 22, 23 to assume a position perpendicular to the axis of the shaft 27 will press the pyrophoric elements 24, 25. against the abradant surface causing sparks to be emitted, the light of which will shine through the material 51, 52 in the opening 49, 50. As soon as pressure u on lever 34 is relaxed, the gear 30 will imme iately drop out of mesh with ."the pinion 29, permitting the disk 26 to spin freely without drag ing therewith the gear 30, re-

sulting in a ree revolution of the'disk 26,

retarded only by friction: of the p'yrophoric elements.

Minor changes in the physical embodiment of the invention may be made without departing from the spirit thereof within the sco e of the appended claims.
