ARONSON, OF NEWARK, NEW .1 ERSEY, ASSIGNOR TO ART METAL WORKS, TNQ, A CORPORATION OF NEW JERSEY SPARRING TOY Application filed May 3, 1928. Serial l lo-274,688.

My invention relates to sparking toys and the main object of the invention is to provide a simple and efiicient toy which upon being whirled first in one direction and then in the 5 other direction, will produce a series of sparks. Further and more specific objects, features and advantages will more clearly ap pear from the detail description given below taken in connection with the accompanying drawings which form a part of'this specification.

In the drawings, Fig. 1 is a perspective of a device embodying the invention in one form. Fig. 2 is a transverse section of the whirling members thereof, Fig. 3 illustrates inperspective the various parts thereof disassembled, Fig. 4 is a view similar to Fig. .1 illustrating a modification, Fig. 5 is a transverse section of the whirling members of the device shown in Fig. 4, and Fig. 6 is a perspective of the various partsthereof disassembled. X

Referring to Figs. 1, 2 and 3,-7 and 8 represent two sheet metal discs, each provided with openings or windows 9' and centrally disposed

holes

10 and 11 respectively. Arranged fiat against the inside faces of the discs 7 and 8 and so as to cover the window openings 9 and form colored panes therefor, are colored celluloid sheets 12 and 13-respectively, these sheets being provided with centrally disposed holes 14 and 15 respectively. Arranged'flat against the inside faces of the

sheets

12 and 13 are

discs

16 and 19 respectively having abradantsurfaces on their inside faces. These sheets may be formed of heavy emery paper and like the

sheets

12 and 13, may be shaped in the form of discs. They are also provided with central holes.18 and 17 respectively. 20 represents a spacer comprising a tubular member internally screw: threaded at each end thereof. 21 and 22 represent U shaped members each provided with erforated outwardly extending ears 23. The

ase ortions' of these U shaped members are provided with holes adapted to receive the

screws

24 and 25 respectively.

The

discs

16, 12 7 and the member 21 are all rigidly secured to one end of the spacer 0 20 in the order named by the screw 24 which which passes through the

holes

11, 15 and 17 i and engages with the screw threads in said other end of the spacer 20. The parts so far described are thus all rigidly connected together and form a unitary whirling member. The discs 7 and 8 are provided with stamped out inwardly facing

grooves

28 and 29 respectively at their peripheries which aid in giving rigidity to the discs.

J ournalled on the spacer 20 and freely rotatable about the' same, is a weighty disc member 26 preferably composed of a relatively thick piece of iron or steel and provided with a plurality of spaced holes therethrough, through which are inserted and rlgidly secured sticks of pyrophoric alloy material 27, which project from both sides of the disc 20 and are adapted to engage the

abradant surfaces

16 and 19 respectively when the device is whirled.

Passing through the apertures in the ears of the U shaped member 21 are the ends of two lengths of

string

30 and 31 respectively. The ends are knotted to prevent them from slipping out of the apertures. The outer ends of these strings are integrally or otherwise connected to form a loop which passes through a hole in a wooden ball 32. Passing through the apertures in the ears of the U shaped member 22 are the ends of two lengths of

string

33 and 34 respectively, the ends of which are also knotted to prevent them from slipping out of the apertures. The outer ends of these strings are also integrally or otherwise connected to form a loopwhich passes through a hole in a wooden ball 35.

In operation the operator firmliy gras s the

balls

32 and 35, one 1n each han and w y alternately pulling the same apart to put the strings under tension and then rellevln the tension, the strings are caused to be twisted first in one direction and then in the other direction in a manner well understood by those skilled in the art. This causes the whirling member comprising the discs 7 and 8 andfarts rigidly connected thereto, to be rotate first rapidly in one direction and then quickly reversed and rotated rapidly in the other direction and so on, alternately, with the change from one to the other taking place suddenly. The member 26, however, because of its weight and the momentum due thereto, lags behind the other parts in the rotation thereof, so that the discs 7 and 8 and the

abradant material

16 and 17 respectively carried thereby, are caused to rotate with res ect to the pyrophoric pieces 27 engaging t e same, whereby the pyrophoric pieces 27 are abraded causing showers of sparks to be issued therefrom which are visible through the window openings 9 as well as through the peripheral opening between the discs 7 and 8. Through this opening the sparks will appear to be white or of natural color and the sparks may be projected radially beyond the edges of the discs 7 and 8. The disc 12 may be colored red and the disc 13 may be colored green, whereby the sparks when viewed through the thus colored window-panes on one side will appear to be red and when viewed through the thus colored window panes on the other side, will appear to be green.

Referring to Figs. 4, 5, and 6, the

parts

7, 8, 12, 13, 16, 19, 20, 26 and 27 are the same as Figs. 1, 2 and 3 except that the

discs

12 and 13 are each variegated in color. For example, they are provided with central bands colored red and outside bands 37 colored blue, so that when viewed from either side the sparks will appear alternately as of red and blue color. Instead of using the

screws

24 and 25 and U shaped

members

21 and 22, in this form, I have substituted therefor screws 38 and 39 provided with

heads

40 and 41 respectively through which extend apertures 42 and 43 respectively. A string 44 is tied together at its ends forming an endless string passing through the aperture 42 and through the wooden ball 32 so that there are in effect two strings extending from this side of the whirlmg member. Another string 45 is also tied together at its ends to form another endless string which passes through the aperture 43 and through the ball 35, so that there are in effect two strings extending from the other side of the whirling member, and the device may be operated thereby in the same manner as described in connection with Figs. 1, 2 and 3. i

Also in Figs 4, 5 and 6, I have shown a sheet metal band 46 extending around the periphery of the device so as to substantially enclose the disk 26 and other parts between the discs 7. and 8. The band 46 is held in place by havmg its edges seated in the

grooves

28 and 29. The band-46 is provided with window openmgs 47 and laid on the inside of the band 46 is a band of colored celluloid 48 to provide colored trans arent panes for the window openings 47 tirough which the sparks may be viewed when looking at the device radial- 1y. The band 48 may be variegated in color so that the sparks appearing through the window openings 47 will appear to be of various colors.

While I have described my improvements in detail and with respect to certain preferred forms thereof, I do not desire to be limited to such details or forms since many changes and modifications may be made and the invention embodied in widely different forms and kinds of devices without departing ,from the spirit and scope of the invention in its broader aspects.
