HAZEL B. LAUGENOUR, OF OAKLAND, CALIFORNIA.

STAGE APPLIANCE.

Specification of Letters Patent.

Application fi1ed December 4, 1911. Serial No. 663,708.

T 0 all whom it may concern:

Be it known that I, HAZEL B. LAUGENOUR, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Stage Appliance, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a tank used upon the stage for the purpose of displaying the skill of a swimmer to an audience, and its especial object is to provide means whereby a rapidly moving current of water may be produced in order that a tank of the minimum size may be used, while at the same time the skill of the swimmer is displayed, notwithstanding the fact that the swimmer remains in substantially the same place throughout the exhibition.

In the drawings in which the same numeral of reference is applied to the same portion throughout the several views, Figure 1 is a plan view of the tank illustrating the application thereto of a motor and pump for producing the current. Fig. 2 is an end elevation of the tank, showing the supporting wheels. Fig. 3 is a side elevation of the tank, showing the supporting wheels and looking at the glass front. Fig. 4 is a detail of a corner of the tank, showing the manner of securing the sides to the bottom, and Fig. 5 is a plan View of a portion of the corner of the tank with the top rail removed therefrom, showing the means for securing the glass front in place.

The numeral 1 represents the supporting joists, there being four of said joists, each joist being provided with a pair of wheels 2 to facilitate moving the tank about upon the stage. The joists support a floor 3 said floor having an extension at l on one side of the tank to provide a suitable support for a motor M and pump P.

It will be observed that the tank is divided into two parts for convenience in transportation and that all of the other parts of the tank may be disassembled from the bottom when it is desired to ship the tank from place to place.

The ends of the tank 6 are formed of any suitable material and have angle plates 7 on the edges thereof, and an angle plate 8 at the bottom to facilitate securing said end to the bottom of the tank and to the corner piece 9, suitable bolts 10 securing the end to the bottom and to the corner piece. Each end 6 is provided with a funnel 11, in the front of which is a shield 12, bars 13 securing said shield in place in front of the funnel, the object being to prevent the direct impact of the water upon the swimmer and to more evenly distribute the current. On the outside there is a collar 14: for connecting to an oppositely disposed collar 15 on the pipe lines 16, said pipe lines being connected respectively to the intake and outlet of the pump so that the water handled thereby is simply pumped from one end of the tank to the other end thereof.

The back of the tank 17 may be in two Patented Dec. 10, 1912.

pieces, one for each half of the tank, suitable flanges 18 being used for securing each piece of the back to the bottom, while an arch 19 made of T bar is used to secure the two pieces together, as well as to provide means whereby the tank is prevented from spreading at the center, said arch passing from the bottom of one side thereof up over the top and to the bottom on the other side thereof.

The uprights 9 at each end of the tank on the front side, each have a plate 20 secured thereto, as indicated on Fig. 5, said plate forming the means whereby the base boards 21 are secured to the ends and also forming the means whereby the glass windows 22 are secured to the end pieces 9. On the lower edge the side pieces 21, are each provided with an angle bar 24, said angle bars forming the means whereby the side pieces are secured to the bottom of the tank. Suitable bolts 25 connect the angle bars 24- and the tank bottom.

On the upper edge of each of the side pieces 21, there is a plate 26 suitably bolted thereto and against which the glass is secured. Connected with the end piece 9 is a top angle bar 27, which extends across the arch 19, one of said bars being connected to each end piece 9. Connecting the side piece 21 and bar 27, is a T bar 28. The two top bars 27 and the two side pieces 21 are suitably connected to the bottom and end pieces and are then connected to the arch 19, by means of bolts, whereupon the glass may be inserted in the four openings thus produced. Each glass has a suitable gasket 29 laid adjacent the outer flange of the angle bars and plates 26, whereupon the glass is inserted in place and another gasket is then placed on the inner side of the glass, whereupon plates 30 are placed against the gasket and bolted tight against the glass, the plates 30 extending entirely around the inner side of the windows produced.

When the tank is properly assembled and all of the joints made water tight, it may be filled and is ready for exhibition. purposes, whereupon the swimmer may jump into the Water and can give an exhibition in-swimming in a current of any desired velocity, the velocity being dependent upon the amount of power available for pumping purposes. It is of course desired to use such a current as will maintain the swimmer in a position as nearly fixed as possible in order that the tank may be made as small as possible, and to prevent the swimmer from striking the tank, while at the same time she remains in full view of the audience. Another advantage of this form of tank is that it has no very large pieces, all of the parts being readily dismounted for shipment.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows:

, 1. In a stage appliance, a swimming tank having windows on one side thereof and means to discharge a current of water from one end to the other end of the tank, as described.

2. In a stage appliance, a swimming tank having Windows on one side thereof, means to cause a current of Water to travel from one end of the tank to the other, and means to equalize the current throughout the entire area of the tank, as described.

3. In a stage appliance, a sectional swimming tank, an arch to which the sides of the tank are connected near the center thereof, and means to cause the water in the tank to. travel from one end to the other end thereof,'as described.

4. In a stage appliance, a sectional swimming tank, an arch in which the sides of the tank are connected near the center thereof, the front of said tank having glass windovvs, means to discharge water from one end of the tank to the other, and means to substantially equalize the current of water throughout the tank, as described.

5. In a stage appliance,a swimming tank having windows on one side thereof, inlet and outlet pipes for supplying water to the tank and for conveying the same away, a pump connected with the pipes, funnel shaped inlets and outlets for the pipe lines leading to said pump and shields in front of said funnels to substantially equalize the rate of movement of the Water over the entire area of the tank, as described.

In testimony whereof I have hereunto set my hand this 25th day of November A. D. 1911, in the presence of two subscribed witnesses.
