8 Claims.

My invention relates to exhibition devices for parades and the like-and includes among its objects and advantages the provision of an improved smoke trail baton.

In the accompanying drawing:

Figure 1 is an elevational view of a baton in accordance with my invention;

Figure 2 is an enlarged sectional view along the line 2-2 of Figure Figure 3 is a plan View of the top end of the baton;

Figure 4 is a sectional view on the line 4-4 of Figure 2;

Figure 5 is an elevational View of a smoke cartridge; and

Figure 6 is a fragmentary sectional view of the smoke cartridge illustrating a U-shaped steel strap for removing the cartridge from its containing barrel.

In the embodiment selected to illustrate my invention, the baton I 0 comprises an outer shell or tube I2 of tapered contour. To the top end of the tube I2 ismounted a hollow ball I4 having a smoke hole I6 through which the smoke issues. .Inside the tube I2 is positioned an inner tube I8 of uniform diameter and of such size as to fit snugly at its inner end with the tube I2, as at 20. This inner tube contains the smoke cartridge 22.

A ring 24 is fixed to the upper end of the tube I8 and is provided with two pins 26 receivable in bayonet slots 28 in the neck 30 of the ball I4. This neck fits snugly on the ring 24 but the ball I4 may easily and quickly be removed by reason of the bayonet slots 28. I

The smoke cartridge 22 includes a paper shell 32 and a composition 34 which, when it burns, emits thick smoke. Such composition may be similar to that employed in smoke bombs of the kind which emit black smoke and need not be described in detail. Since the cartridge 22 extends through the ring 24, the smoke may enter the ball I4 and pass to the atmosphere by way of the smoke hole I6. A fuse 36 is incorporated in the cartridge 22 and its end 38 is accessible for lighting purposes through mere detachment of the ball I4 from the ring 24. Replacement cartridges are also easily placed in position when the ball I4 is removed. The paper shell 32 is treated so as to render it fire-resistant to the end that the shell may be removed intact after the composition 34 has burned, therebyfacilitating insertionof the replacement cartridge.

To facilitate removal of the paper shell 32, a U'-shapd member 40 is provided which fits snugly inside the inner tube I8 and is fashioned with ears 42. The ears 42 are manually accessible when the ball I 4 is detached from the ring 24 so that a good grip may be had on the member 40. The member 40 is preferably formed of a relatively thin steel strap and has its bight 44 engageable with the inner end of the paper shell l8 soas to constitute an eflective lift for the shell.

A metallic mesh tube 46 is positioned axially of the smoke cartridge 22. Thus the tube 46 is surrounded by the composition 34, and one end of the tube 46 is in communication with the openings 48 in the bight 44 and the bottom of the paper shell or tube 32. The small end of the tube I2 is provided with an opening 50 to place the metallic mesh tube 46 in communication with the atmosphere. Thus the metallic mesh tube 46 provides air distribution for the burning composition so as to insure effective combustion thereof.

Rows of openings 52 are provided in the tube I2 for cooling purposes. While the inner tube I8 fits snugly inside the tube I2 for support, the

upper endof the tube I2 may be welded to the ring 24 so as to support the tubes I2 and I8 in concentric relationship at their upper ends. Both the tubes I2 and I8 are formed of relatively thin sheet metal for weight reducing purposes.

Without further elaboration, the foregoing will so fully illustrate my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
