EiPECIFICATION forming part of Letters Patent No. 726,854, dated May 5, 1903.

I Application filed March 2,1903. b'erial No. 145,652. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN L. BRINK, a citizen of the United States of America, residing at Baldwin, in the county of St. Croix and State of Wisconsin, have invented certain new and useful Improvements in Canes, of which the following is a specification.

My invention relates to'certain new and useful improvements in canes; and its object is to provide a device of this class for use in political rallies and similarcelebrations or for use as a toy. The peculiar features and advantages of this device'will become apparent in the specification, and they are fully illustrated in the drawings furnished herewith.

In the aforesaid drawings, Figure l is a side elevation of my improved cane, and Fig. 2 is a longitudinal diametrical section through the same.

Referring to the drawings, A is the outer tube of the cane. It maybe of any desired cross-section, althoughv preferably circular, and it is preferably constructed of sheet metal. Within the outer tube A is a second tube B, which can be moved longitudinally with respect to the tube A. To the upper end of the tube B is secured a handle I) of any desired form. In the bottom of the tube A is a check- Valve Ct. Opening inward and below this check-valve a are a plurality of perforations 0,, adapted to admit air. A suitable packing-ring b surrounds the lower end of the tube B, causing it to fit tightly within the tube A like a piston. In theupper end of the tube Bis secured a squawker 0 or some other device adapted to make a noise when air is forced through it. The device'here shown consists merely of the common perforated cylinder c and an elastic rubber band 0', stretched acrossthe perforation. 1 A spiral spring D holds the tube B normally in the position shown in Fig. 2, wherein its upper end is forced a considerable distance from the tube A. p

The operation of the device will now be readily apparent. When the cane is placed upon the ground and pushed down, the two tubes A and B telescope together, thus contracting the space contained between them and forcing the air out through the squawker orother device and making a noise. When the cane is removed from the ground, the spring D forces the parts back to theiroriginal positions and air enters through the valve at the bottom. If desired, this valve may be dispensed with altogether and air can be allowed to go in through the squawker as it does in an ordinary toy balloon; but a smaller quantity of air willanecessarily be admitted, and the device will not work so satisfactorily.

Near the top of the tube Bis a rubber bulb E, communicating with the interior of the tube by suitable perforations 17 The purpose of this bulb is' to provide a small reservoir for compressed air to prolong the sound. When a particularly long sound is desired, the hole in the squawker O can be closed with the thumb and this bulb pumped up by pushing the cane on the ground several times, after which the thumb may be removed and a long sound produced. To enable the bulb to be so pumped up, asecond check-valve b is provided at the lower end of the tube B. This bulb I consider to be a-great addition to the cane, although its removal will not make the device entirely useless for the purpose for which it is intended.

The bottom of the cane is shown provided with an end piece F,provided with a central depression f, the object of which is to make the cane more desirable .for celebration purposes by providing a socket for fire-crackers. Furthermore, the device may be used as the stick for umbrellas, which are also often used for advertising or campaign purposes.

I realize that considerable variations are possible in the detailsof this construction without departing from the spirit of the invention, and I therefore do not intend to limit myself to the specific form herein shown and described, except as pointed out in' the claims.

I claim as new and desire to secure by Let ters Patent 1. The combination with a cane, of an expansible reservoir for air, adapted to be contracted to compress the air as the-cane is pushed upon the ground,and a suitable soundproducing wind instrument communicating with said reservoir.

2. The combination with a cane having a contractible air-space within it, the air within said space being compressed when the cane is pushed upon the ground, of a suitable soundproducing wind instrument communicating with said reservoir.

The combination with the hollow wall of a cane, of a piston slidable therein and relatively movable-with respect thereto by contracting pressure upon the two ends of the cane, and a suitable sound-producing Wind instrument communicating with the space within said outer wall.

4. In a cane, the combination with the outer tube, of a second tube telescoping therein, a spring adapted to hold said tubes distended, and a suitable noise-producing wind instrument communicating with the interior of said tube.

5. In a cane, the combination with an outer tube, of an inner tube telescoping therein, a spring adapted to hold said tubes distended, a check-valve opening inward in one of said tubes, and a suitable noise-producing wind instrument communicating with the interior of said tubes.

6. In a cane, the combination with an outer tube, of a second tube telescoping therein, a

spring adapted to hold said tubes normally distended, a suitable noise-producing wind instrument supported by one of said tubes and in communication with the interior thereof, and an elastic reservoir for compressed air communicating with the space inclosed by said tubes.

7. In a cane, the combination with an outer tube, of asecond tube telescoping therein, a spring adapted to hold said tube normally distended, check-valves opening inward in the bottom of each of said tubes, a suitable noiseproducing wind instrument supported in the inner tube in communication with the interior valve, and an elastic reservoir for compressed air communicating with the space inclosed by said inner tube.

In witness whereof I have signed the above application for Letters Patent, at Baldwin, in the county of St. Groix and State of \Visconsin, this 27th day of February, A. D. 1903.

JOHN L. BRINK.
