BUBBLE-PIPE.

SPECIFICATION forming part Of Letters Patent N0. 432,415, dated July 15, 1890.

Application filed February 12, 1890- Serial No. 340,167. (No model.)

To aZZ whmn it may concern.-

Be it known that I, ALONZO LEWIS, of Baltimore, in the State of fMaryland, have invented a new and Improved Bubble-Pipe, of which the following is a full, clear, and exact description.

My invention relates to improvements in pipes for blowing bubbles; and the object of my invention is to provide a simple and inexpensive pipe that is especially adapted for use in blowing bubbles, and that will hold the water in such a manner that it will not be spilled.

To this end my invention consists in a hubble-pipe constructed substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views. Figure 1 is a vertical section of the pipe embodying my invention, the same being filled with water ready for use; Fig. 2, a vertical section of the same on the line 2 2 of Fig. 1; Fig. 3, a horizontal section of the same on the line 3 3 of Fig. 2, showing the bubble-tube closed; and Fig. at, a horizontal section of the same, showing the bubble-tube open.

The bowl A of the pipe is made of wood, metal, or of any suitable material, and is preferably cylindrical in form. It is provided with a removable top or cover A and with a block B, which fits closely in the lower part thereof. The block B is provided with a horizontal bore 0, which extends entirely through the same, and in which are located the slideblocks D D the block D being shorter than the block D, with a central vertical bore C extending through the same, and which intersects said bore C, and with a diagonal bore E, which extends from the vertical bore to the outer edge of the block, where it connects with thepipe-stem H. The block D is longitudinally movable in the bore 0, and the blocks D and D are pressed together by the rubber bands a, the ends of which are suitably fixed in the grooves cof the said blocks, as shown, by thread wound in the annular grooves b and over their ends. Fixed to the block D is a rod d, which lies in the longitudinal grooves e of the blocks D D and extends through the opening f in the side of the pipe-bowl A, so that by pressing inwardly upon the end of the rod d the block D will be pushed outwardly and the blocks D and D forced apart. I do not confine myself to the use of rubber bands to hold the blocks D and D together, as suitable springs or other elastic material might be substituted.

Extending through the vertical bore of the block 13, between the blocks D and D, is a rubber tube F, the upper end of which extends slightly above the block B, and into the water in the bowl A, and the lower end of which projects through the bottom A of the pipebowl, passing through a perforation in the same. The tube is provided upon one side with an opening (,which connects with the diagonal bore E, and thence with the pipestem H. It will be seen from the above description that the tube F will be normally closed by the pressure of the blocks D D upon it, and that when the blocks are forced apart by the rod d the tube will be opened.

The bowl A of the pipe above the block B is filled with soapy water, and the device is operated as follows: The operator. presses slightly on the rod d, thus forcing the blocks D D apart and allowing a minute quantity of water to flow into the tube F. The pressure is then removed from the rod and the blocks close the tube, as described. The operator then blows through the pipe-stem H, and the air will pass through the stem, th rough the bore E of the block B, and through the opening g and tube F. There will be sufficient moisture in the tube F to form a bubble, which will be blown from the lower end of the tube, as shown in. Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A bubble-pipe comprising a reservoir, a rubber outlet-pipe having a clamp or compress engaging it transversely to close its bore by compression, means for releasing said clamp or compress, and a blow pipe or stem communicating with said rubber tube below its clamp or compress, substantially as set forth.

2. A bubble-pipe consisting, essentially, of a bowl having a stem attached to the lower part thereof, a block fixed in the lower portion of the bowl, having avertical bore there= in, a rubber tube extending through said vertical bore, a diagonal bore connecting said tube with the pipe-stem, a horizontal bore extending through said block, and a clamp 01' compress for opening and closing the rubber tube, substantially as described.

3. In a bubble-pipe, thecombination, with a block located in the lower part of the bowl, provided with a diametrical bore, a central vertical bore, and a diagonal bore, and a tube located in said vertical bore, of two springaetuated blocks located in said diametrical bore at the sides of said tube, and means for separating the blocks, substantially as described.

4. The combination, in a bubble-pipe, with the pipe-bowl A,havinga stem H fixed in the lower part thereof, of the block B, having the rubber tube F extending vertically through the same, the bore E, extending from the pi pestem to a perforation g in said tube, and means, as spring-actuated blocks D l) and rod (Z, for opening and closing said tube, substantially as described.

5. The combination, with the pipe F, arranged in the block B, as shown, and having means, as described, for blowing air and wator through the same, of the blocks 1) I), having springs to hold the same against the tube F to close the tube, and having a rod (l, connecting the block D with the outside of the bowl, whereby the block may be moved and thetube F opened, substantially as described.

ALONZO LEWIS.
