ROKURO KOHARU, OF NEW YORK, N. Y.

SIPI-IQN.

T '0 all whom it may concern:

Be it known that I, Roitrfuo IIOHAR'U, a subject of the Emperor of Japan, residing in the city, county, and State of New York, have made a certain new and useful Invention in Siphons, of which the following is a specification.

This invention relates to siphons. I

The object of the invention is to provide a construction of siphon device which is simple, inexpensive to manufacture, easy to manipulate, adjust and clean and effective in operation, for use in the houshold, hospitals, restaurants, cafes, hotels, laboratories, or the like to separate liquids from each other.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawing, and finally pointed out in the appended claims.

In the drawing,Figure l is a view in Vertical sectional elevation of a siphon embodying the principles of my invention, and showing the application of the same for use. Fig. 2 is a detail View showing the adjust able support for the siphon. Fig. 3 is a broken detail of a slight modification.

The siphon consists of an enlarged chamber C, having straight angularly related legs D, E, communicating independently and directly therewith and extending therefrom, said legs being of the same internal diameter or area in cross section, but the leg D, which I will call the inlet leg is shorter than the leg E, which I will call the discharge leg. The enlarged chamber C, and the straight angularly arranged legs D, E, are made in one integral piece, and may be made of any suitable material. I have found that glass is a suitable material out of which to make the device, though, of course, my invention is not to be limited or restricted in this respect. The upper portion of the enlargedchamber C, is formed into a neck B, over which tightly engages and fits the nipple of a compressible bulb or ball A.

F, is a bottle, jar or other container for the liquids to be separated, and G is a receiving pan or receptacle for the separated liquid.

H, is an adjustable supporting device for the siphon. This is in the form of an adjustable strap arranged to embrace one of the siphon legs and carrying a bracket to Specification of Letters Patent.

rest on the upperedge of the receptacle in connection with which the device is used.

In practice I prefer to terminate the lower end of the inlet leg D, in a plane inclined to to the plane of the surface of the liquid to be separated, as indicated at J. l have found that a better siphoning and separating action is attained when this condition is observed.

A siphon device embodying the structure as above set forth is not only exceedingly simple and inexpensive, but is: effective in operation, the operation being as follows: The inlet leg I) immersed into the liquid to be drawn off or separated, and preferably to the lowermost depth of such liquid, while the discharge leg is directed over or into the receiving receptacle. The bulb A is then compressed and then the finger is placed over the lower discharge end of the discharge leg E, so as to tightly close the same. The bulb is now released and thereupon the liquid into which the leg D has been immersed rises through said leg into the chamber C. By removing the finger from the lower end of the leg E, this liquid flows out of chamber C, through the leg E, and into the receiving receptacle G, thus starting the flow of the liquid which flow is maintained until the bulb A is again compressed, or the liquid to be separated is exhausted or the siphon. is removed. The inclined lower face or end surface of the leg D facilitates the starting of the flow. By suitably adjusting the supporting device H, on the leg D, the depth of immersion of said leg in the liquid to be drawn off may be regulated, said de vice, II, also serving to support the siphon.

It may sometimes be desirable to avoid using the finger to close the lower or discharge end of the discharge leg in starting the siphon action, as, for instance, when said leg is inserted into a deep receiving receptacle where it is diflicult to reach the discharge end of said leg. In order to avoid this difliculty, I may employ a sleeve K, of rubber or other suitable material and having an end flap L. This sleeve is slipped over the lower end of leg E and the flap L, nor mally operates to close yieldingly against the lower open end of leg E. Whenever the bulb A is compressed the air forced out of the siphon through leg E will cause the flap L to open, and when the compressed bulb is released the flap will automatically close. When the flow of liquid commences the weight thereof imposed on the flap L will cause said flap to open.

A siphon device as above described, em bodying the straight legs D, E, merging in dependently and directly into the enlarged chamber C, permits the device to easily and thoroughly be cleaned by inserting a cleaning brush and working the same back and forth longitiulinally of said legs. T his is an important matter especially when the de vice is employed. to separate cream from milk for food purposes. in the use of the device a. perfect and complete separation is effected.

The combined volume of the enlarged chamber C and legs D, E, should be the same as the volume of the compressible bulb A, to secure the best results.

Having now set forth the objects and nature of my invention and a device em bodying the principles thereof, what I claim as new and useful, and of my own invention and desire to secure by Letters Patent is,-

1. A siphon comprising an enlarged chamher having straight legs each communicating independently therewith and extending therefrom but formed in one piece therewith, and a compressible bulb associated with said chamber.

2. A siphon comprising an enlarged chamber having a neck and straight legs each communicating independently with the chamber and eXtending therefrom in angular relation to each other, said chamber, neck and legs being formed in one piece, and a conun'essible bulb fitted to said neck.

2: A siphon comprising an enlarged chamber having a neck and straight legs all formed in one piece said legs communicating indepmidently of each other with said cham her, and a compressible bulb fitted to said chamber neck, the combined volume of said chamber and legs corresponding to the VOlume of said bulb.

at. A siphon comprising an enlarged chamber having a neck and straight legs all formed in one piece each communicating independently of each other with said chamher, a con'lpressible bulb fitted to the chamber neck, and a yielding flap applied directly to the open end of one of said legs.

In testimony whereof I have hereunto set my hand in the presence of the subscribing witnesses, on this 17th day of hilarch A. 1)., 1910.
