COCK FOR SIPHONS.

SPECIFICATION forming part of Letters Patent No. 317,465, dated May 5, 1885.

Application filed October 20, 1884. (No model.)

To afZZ whom, it may concern.-

Be it known that I, FREDERICK W. LYnAN, a citizen of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Cocks for Siphons, 8vo., and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

rIhis invention relates to that class of cocks designed for use in connection with an elastic bulb or other device, for exhausting air from a siphon-tube, and thereby starting the dow of liquid. Devices of this character have been heretofore variously arranged, as, for instance, the long leg ot a siphon has been fitted with a cock the plug of which was provided with a through way or channel, and a smaller or by Way communicating with a piston or pump cylinder secured to the top of or form- Aing part of said plug. And, again, the long leg of the siphon has been fitted with an elastic bulb, on either side of which was placed a valve opening toward the discharge end of the siphon, a device being provided to hold one of the valves closed when desired.

Owing to the cost or complicated nature of construction, or unsatisfactory operation of this class of devices, they have not, so far as I can learn, come into general use.

The obiect of this invention is to construct a siphon-cock which can be produced at a small cost, and which, when combined with a siphon-tube and its air-forcing apparatus, will prove effective and reliable in operation.

The invention consists in novel features of construction and combinations of coactin g parts, which will be first described in the ensuing specification and claimed in the clauses at the close thereof.

In the accompanying drawings, Figure 1 is a sectional view'of my siphon bulb and cock, the latter being set to shut off the flow of liquid. Fig. 2 is a similar view, the cock in this figure, however, being shown in a position to start the flow of liquid. Fig. 3 is a sectional view of the cock showing it fully openmay be rigid or flexible, as desired) is attached 4 an elastic valveless bulb, B, and at a point below the bulb is secured the cock-barrel G. This cock-barrel is provided with, the usual cylindrical chamber for the reception of the cock-plug D.

In my preferred form of cock a narrow chamber or passage, c, leads from the inlet end of thebarrel to a point in the plug-cylinder below the main or through way or passage of the cock-plug. For facility ot' manufacture I prefer to form this plug tubular, as shown, the lower end being provided with a female thread to receive a screw-plug, D. This screw plug is provided with a small passa-ge, d', registering, when the parts are in proper position, with a small opening, d, through the threaded portion of the cock-plug D, the screw-plug D being cut away at one side in order that the valve E may be hung upon it to close one end of the passage d. The opening d is so arranged with relation to the coclrbarrel O as to register with the chamber c therein when the plug is in the position shown in Fig. 2, and the cock-plug D is also provided at a point above the screw-plug D with a small opening, d2, which forms, in connection with the chamber c, opening d, and passage D', the by Way or passage of the cock. The plug D is also provided at points above the screw-plug D' with large openings cl3 d3, forming the main passage or way of the cock.

The parts having been properly assembled, as illustrated, it will be seen that a passage of fluid through the cock will be prevented when the plug is in the position shown in Fig. I, but upon turning the plug to the position shown in Figs. 2 and 6, the cock will be open for the passage of a small stream of Huid outwardly,

toward the discharge end of the cock throughthe by-way, this by-way, however, being closed in the reverse direction by the valve E.

IOO

The flow of liquid having been once started through the by-Way by exhausting air from the siphontube in a manner Well known, the

plug may then be turned to open the main.

Way, as shown in Fig. 3. Sufficient liquidhaving been drawn, the plug may be turned to the position shown in Fig. l, thus cutting oft' the flow of liquid, but leaving the siphon in such condition that upon turning the plug to open the main passage the flow of liquid will at once comm ence.

when the plug is turned to a position the reverse of that shown in said Fig. 6.

In lieu of the tubular plug herein described, a sclid plug may be used, the main and by passages being cut at right angles, anda portion of the exterior of the plug, at one end of the by-passage, being cut away to receive the valve.

What I claim as my invention, and desire to secure by Letters Patent, is

l. As a new article of manufacture, a cockplug provided with a main Way and a by-Way at approximately right angles to the main way, and a valve to close the by-Way in one direction, substantially as described.

2. The combination, With a cock-barrel, of

the plug provided With a main Way and aby- Way, and a valve to close the by-Way in one direction, substantially as described.l

3. The combination, With a cock-barrel having a main channel and a by-channel, of the cock-plug provided with a main Way communicating with the main channel of the barrel, and a by-Way communicating With the bychannel thereof, and a valve to close the by- Way of the plug in one direction, substantially as described.

4. The combination, With the cock-barrel having a main and by channel, of the tubular cock-plug provided at a point opposite the main channel of the barrel with large openings forming the mai-n Way of said plug, and a small opening at right angles to said main Way, the lower end of said cock-plug being closed by a screw-plug having a valved passage registering Witli a small opening in the cock-plug, which latter opening registers with the by-channel of the cock-barrel, substantially as described.

5. The Combination, with a Siphon-tube having an elastic bulb, of the cock the plug of which is provided with a main Way and a valved by-Way at right angles to the main Way, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

FREDE RICK W. LYMAN.
