Application filed July 1 1, 1919. Serial No. 310,108.
' be thrown against a surface in a manner whereby, upon the impact of a certain peripheral portion, a detonation is produced without injury to the ball.
Another object is to producea toy particularly' appropriate for boys as an outdoor sport by means of which the muscles of the hand and fingers may be developed and skill acquired in accuracy of handling a ball, particularly with reference to the manipulation of the fingers around the ball and the skilful grasping, controlling and hurling the ball in such a manner as to cause a predetermined point thereon to make contact with the surface struck. It is well known that professional base ball pitchers acquire and make use of such fineness 01' control. The invention affords a useful and ready means to the boy of measuring or determining this ability. 7
A further object is the provision of a ball having a vari-colored exterior in each colored section of which is engaged a paper disk containing materials adapted to detonate upon concussion and to emit a correspondingly colored smoke or gas therefrom.
These and other objects are accomplished by means of suchstructure and novel arrangement of parts as are hereinafter described and shown in the accompanying drawings, which form a part of this disclosure, and which are to' be considered as illustrative and descriptive only and not, as restrictive or limitative, and in which Figure 1 is a perspective view illustrating the ball and results attained thereby;
Fig. 2 is an elevationalview of a ball made in accordance with the invention;
Fig. 3 is an enlarged fragmentary plan view of the same;
Fig. 4: is a partial sectional view thereof,
I .taken onv the line 4:4 of Fig. 3; and
Fig. 5 is a similar fragmentary sectional view showing a modified form of construction.
Similar numerals of reference indicate corresponding parts in the several views.
Referring to the drawings in detail, the numeral 10 will be seen to designate a side walk, and 11 the wall of a building or the like, presenting a rigid surface against which the hand ball, generally designated by the numeral 12, may come in forcible contact, when thrown. These balls are preferably made of a resilient wood or of rubber or fiberoid and of the size of an ordinary base ball. The ball may be constructed with a single detonating unit, but in the adaptation lllustrated, three units are shown and the exterior of the ball is colored red, white 15 and 16, forming tri-colored segments as indicated. This permits of a game being played, which will be referred to later.
Secured centrally in each of the several segments are metal plates or anvils 17, the same being slightly below the peripheral surface of the sphere and held therein by undercut edges, tacks, spurs, cement, or the like. In the modification shown in Fig. 5, in place of the plate 17, the head 21 of a barbed brad or nail 22 may be used as the anvil element, if wood is employed, with equally efiective results. Disposed over these anvil elements are leaf-like cover plates 18 formed with angularly extending elements 19adapted to be forced radially into the material of the ball in the manner of brads or spurs, or, if a rubber ball, solid or hollow, be used, the elements 19 may be suitably cemented, whereby the cover plates are resiliently but permanently secured. Between the fixed plates I7 and the cover plates 18 are recesses adapted to receive disks or paper capsules containing material adapted to detonate by the. percussion of the ball with a surface, affording considerable noise. The edges of the cover plates 18, as well as of the anvil elements 17, may be curved slightly, in
.order to assist in holding the capsules in place. The material in the capsules is also adaptedto liberate colored smoke or gas,
'when exploded. Thus when the ball is thrown against a surface, a report takes vplace accompanied by the liberation of colored smoke, the smoke corresponding in color to the color of the segments of the ball in which the caps are confined. It is obvious that the ball must be thrown with such accuracy and precision that the relatively small area presented by and blue, as indicated by the numerals 14,
the resilient cover plate, 18 is the part of the ball which is caused to come in contact with the surface struck, or the noise and smoke making property of the ball remains quiescent. V
The preferred manner of playing a game with the adaptation illustrated is to load the three recesses with paper caps which produce red, white and blue smoke, respectively- Throw the ball on the sidewalk so as to cause the cover plate 18 holding the cap producing the red smoke to strike the sidewalk and explode the cap; catch the ball as it rebounds, and quickly and with such accuracy of manipulation of the hand and fingers and before the red smoke has become dissipated, throw it again to the sidewalk, this time in such manner as to cause the cap containing the white smoke to explode; similarly catch the ball on the third rebound and as quickly as possible throw it again to the sidewalk in such a manner that the cap containing the blue smoke will explode. If these several actions are skilfully performed, the three explosions occur in sufficiently quick sucbe exploded before the first smoke has become dissipated; and finally, to see who forms the nearest approach to the shape and appearance of the flag through the blending of the liberated smoke waves as they become dissipated in the air.
New caps are entered'into the recesses as they become exhausted, and as new ones are lnserted they push the remains of the old ones out.
V sired; and thatthe free end of the cover It should be noted that any selective combination of colors may be thus produced,
such, asthe national colors of any foreign country, or the colors of a school, fraternity, club, etc., a ball containing a larger number of the detonating units being used, if deplate 18 may be curved slightly, inwardly, in order; to protectit somewhat, and a small groove or depression may extend in the.
surface of the ball, immediately thereunder, to accommodate the curved end of the cover plate, upon concussion. Obviously, minor modifications may be made within the scope of the invention. 7
The various elements may be. constructed 7 in any suitable size and shape and they may be made of any selective kind of. material,
the concussion of said so long as the various members of'the combination coact and cooperate to perform the functions and produce the results contemplated, without departing from the spirit of the invention.

)2. A ball comprising a free unconfined sphere, a detonating'unit engageable at a definite point on the circumference of said sphere, and means for holdingsaid detonating unit in close relation to the surface of said sphere, said holding means permitting the removal of said unit.
3. A handball comprisinga sphere having a substantially non-protuberant surface, an'
anvilelement embedded below the surface of the sphere, and a resilient clip extending 7 sphere, and a spring plate secured in said surface and extending over-said anvil element, forming a space therebetween adapted presenting a space to receive a capsule containing fulminating material, said plate and sa d anvil element adapted to hold said capsule in confinement normally and to detonate the same upon con' cussion of said plate on said sphere with a solid object, said plate being substantially flush with the surface of the sphere.
