9 Claims. (Cl. 240-6.42)

The present application, in general, relates to a head for a baton or the like and, more specifically, to a ballshaped baton head made of translucent material and containing a lamp bulb to light it. The lighted head adds a striking decorative quality to the effectiveness of the baton, making is particularly attractive when being twirled in darkness.

Prior lighted batons have used complicated structures for supporting and wiring the bulb and for switching the bulb on and off. In some prior lighted batons, the components have not been sufficiently rugged and firmly secured together in order to withstand falls, or they have been susceptible to circuit faults arising from the strenuous forces exerted on them in normal use. Centrifugal force, for instance, has had the tendency to make or break the circuit to the bulb at times when such action is not wanted.

The baton head structure according to the present invention materially reduces, if not eliminates, difficulties of the foregoing character, providing a simplified construction of few parts held in rugged association together and establishing a straightforward, essentially fault-free circuit. The head consists of a hollow plastic ball made of translucent material and separable into two halves along a snap-fit joint in order to make the inside accessible for the insertion or removal of an interior lamp bulb. The head slides over a hollow shafted metal baton. The bulb is preferably fixed therein by a metal socket element which holds it in a contacting position with a dry cell within the shaft and which in a surrounding area about the bulb establishes separate contact with the metal end of the shaft to complete a ground return path establishing an electrical circuit through the dry cell.

Both halves of the ball according to the present invention have aligned tubes therein with internal reinforcing webs extending between the inside of each half and the associated tube. One half, forming a body portion of the ball, has an inturned bead or flange as its openable end and is arranged with the tube thereof frictionally engaged to grip the metal shaft, which latter is inserted at the opposite end of the body. The other half covers the open end and has a confronting lip provided with an outwardly directed groove adapted to effect said joint by making a snap fit with the flange on the body.

The plastic construction is a definite advantage because of the effectiveness of the material in producing a positive snap fit as desired and the resulting lightness of the ball offsets to a marked degree the weight of the electrical components required. This plastic is or may be pigmented to form various color combinations. Also, the referred-to frictional grip between the tubes in the plastic ball and the end of the shaft makes possible a simple on-off switch action for axially positioning and grounding or interrupting the circuit of the socket element of the bulb against the steel shaft, thereby lighting the bulb at only the times desired to cause the ball cover to glow. Suitable plastics are polyethylene and styrene.

The accompanying drawings illustrate a presently preferred embodiment of my invention, wherein:

Figure 1 is a longitudinal view of a baton carrying a head embodying my invention;

Figure 2 is an enlarged longitudinal view corresponding to Figure 1 and sectionally showing the head end thereof;

Figures 3 and 4 are end showings viewed in the upward direction in Figure 2 and showing the respective members for providing a socket for fitting the bulb concentrically to the dry cell and for fitting the bulb concentrically to the ball cover;

Figure 5 is a showing viewed in the downward direction of Figure 2 showing the body portion of the ball; and

Figures 6, 7, and 8 are sequence views showing the operation of the device, partially schematically, in switching the bulb on and off.

In particular reference to the drawings, my baton head fits on a baton, generally indicated at 10, having a hollow metal shaft which is capped at 12 at the lower end and in which a series of grooves 14 is turned in spaced points along the length. The opposite end carries a head consisting of the hollow plastic ball 16 which internally supports a penlight type lamp bulb 18 and which is supported with a friction fit on the end of the baton shaft it).

The turned groove 14 adjacent the head end of the shaft forms a circular retainer ridge on the inside which supports the large center section of a double frusto conical coil spring 20. A penlight type dry cell 22 engages the free upper end of the spring 29 and has a positive center electrode 2.4 which engages the bulb 18 on the battery-connected side thereof. Besides acting as a lower cushion or suspension for the dry cell, the double conical spring 20 also acts as the means for electrically grounding the lower negative terminal of the dry cell 22 to the steel shaft 10.

The spring 20 tapers both ways from its larger center section so that, whichever way the spring is placed in the shaft, the center section is fitted on the ridge to retain it and there is a free outer end of the spring 20 on the top side to engage the negative electrode of the cell.

A bulb holder element consists of a threaded socket 26 for holding the threaded end of the bulb in registration with the dry cell electrode 24 and a stack composed of metal washers 28 and a fiber spacer washer 30 which is clamped in rigid contact with the socket to hold the bulb centered within the ball 16. The ground side of the bulb is connected to the metal of the shaft 10 through the lower metal washer 28 forming a contact engageable or disengageable from the bare metal of the shaft.

The ball 16 according to Figure 2 consists of a frusto conical body 32 open at both ends and a cover 34 which closes the larger end of the body. The body has an inwardly turned bead or flange 36 at the larger end and a tube portion 38 is integral with the small end of the body and extends axially therein for a substantial portion of but not all of the length of the body. The body 32 has a pluralityfour, as illustrated in Figure 5-of reinforcing webs 40 which extend radially between and are integral with the insideof the body and the tube portion 38 and also with the floor of the body 32..

The webs 40 reinforce the body 32 when the baton is dropped and the head strikes the ground. The tube portion 38 holds the webs in place relative to the shaft and prevents their inner edges from sliding around the tube portion on the baton when it is twisted, either from a blowor by hand. The tube also frictionally fits over the shaft 10 and holds the head on the shaft.

The cover 34 has sides 34a in continuation of the sides 32a of the body and contains a second tube 42 concentric with the cover 34 and integral therewith. The

tube 42 is aligned with the tube portion 38 but has a bore of slightly lesser diameter. A larger set 'of webs 44- twice the number of the webs 40, as illustrated in Figure 4-extend radially between and are integral with the inside of the cover 34 and=the tube-42and also with the floor of the cover 34. The tube 42 and the webs 44 reinforce the cup in the same manner as the tube portion 38 and the webs 4t) reinforce the body 32.

The tube 42 provides a container or globe for the lamp bulb 18 which is located behind a formation in the floor end of the cover 34-. As shown in Figure 2, the central portion of the cover opposite the tube 42 is thicker than the edges and has essentially the function of a lens. Also, the end of the elongated tip of the bulb 18 is provided with a lens through which a portion of the light emitted from the bulb is concentrated into a beam directed against the lens portion at the end of the cover 34.

For purposes of replacing the bulb 13, the ball 16' is separable along a juncture line 46 and it is relatively simple to pry sit the cover 34 from the body by inserting and twisting a key, knife, or screwdriver at-the juncture line 46. The stack of Washers serve as a mounting flange which detachably seats the bulb 18 in the cover, and for accommodating same the webs 44 have portions extending beyond the lower end of the tube 42 to form the fingers of a springable container socket 48 disposed between the tube 42 and the tube 38 which frictionally gripsthe stack of circular metal washers and fiber washer, 28 and 30, respectively.

To assemble the parts of the ball, the bulb 18 is threaded into the socket 26 and thereafter the bulb and socket are forced into the container socket 48 of the cover 34. Then the cover 34 is placed over the larger end of the body 32 and given a sharp rap. In this manner, a raised circular lip 50 carried by the cover is forced within the flange 36 so that this flange and a groove 52 formed around the lip make a snap fit.

Thereafter, the shaft is introduced into the open end of the ball 16, as illustrated in Figure 6, and, as shown in Figure 7, they are telescoped together to a point establishing initial contact between the bulb 18 and the positive center electrode 24 of the dry cell. At and past this point, the battery suspension spring 20 is compressed to maintain an electrical contact between the bulb and the positive electrode 24. This biased relationship between dry cell and lamp bulb in their normal position is illustrated in Figure 2.

When the bulb 18 is to be lit, the ball 16 is moved by hand to the position shown in Figure 8 in which the ground-connected side of the bulb completes a circuit through the lower washer 28, the body of the shaft 10, and the spring 20.

It should be noted that centrifugal force exerted outwardly along the axis of the shaft in the direction of the arrows of Figure 1 merely augments the force of the spring 20 to keep the dry cell 22 of Figure 8 in contact with the battery side of the bulb. Similarly, from Figures 2 and 7, it can be seen that the centrifugal force in no way tends to re-establish the circuit when unwanted, in view of the positive separation of the socket washers 28 and the bare end of the shaft 10. To replace the dry cell 22, the ball 16 is pulled off the shaft and the shaft is turned downwardly.

I prefer to make the present baton head of a non-con ducting plastic or synthetic resin, such as polyethylene, which can be given bright, clear colors and which has a high gloss surface but is nevertheless translucent to produce the proper glow in the cover 34.

Although the present ball 16 for the baton head is essentially hollow, it can withstand repeated blows, and its yieldable plastic composition can be inexpensively molded into the intricate shapes shown. The washers 28 and 30 protect the interior of the ball from chafing by the sharp edges of the shaft 10. Also, as indicated, the lower washer 28 constitutes the movable contact of an on-otf switch in cooperation with the end edge of the shaft 10 and additionally transmits the full axial component of the shocks of falling thereto.

The use of reinforcing webs in the body 32 and the cover 34 and especially the use of a greater number of webs for the cover securely buttresses the ball 16 from side shocks from falls.

While the foregoing disclosure describes a presently preferred embodiment, it is to be understood that the invention may be practiced in other forms within the scope of the appended claims.
