N0. 443,496. Patented Dec. 30, 1890.





SPECIFICATION forming part of Letters Patent No. 443,496, dated December 30, 1890.

Application filed June 11, 1890. Serial No.354,992. (No model.)

To aZZ whom it may concern.-

Be it known that we, SYLvANUs F. BOWSER and AUGUSTUS BOWSER, citizens of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Portable Siphons; and we do hereby 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.

Our invention relates to improvements in portable siphons of the well-known variety which has for its object the decantation of casks, barrels, and analogous vessels; and the objects of our improvements are, first, to provide the well-known tw0;1imb siphon with a sure and inexpensive means for starting its flow; second, in attaching an exhausting and forcing pump at or near the lower extremity of the short limb of a siphon in such a manner as that the said limb of the siphon and the barrel of the said pump shall be separate members of the same instrument, but shall have a common fluid inlet or inlets, which inlets shall be located between and near the connecting extremities of the said members, saidinlet being provided with an inwardlyopening valve, which is adapted to be opened and closed by, the pulsatory action of the piston within said pump, and also adapted to be opened by and kept open by the flow of the fluid through the said siphon when once the said flow shall have been established by the ejecting action of the said piston. WVe attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the entire apparatus with the operating-piston down and the foot-valve closed. Fig. 2 is a vertical section of the apparatus having the long limb and a part of the short limb of the siphon removed and representing the piston at its high est altitude and the foot-valve open.

Similar letters refer to similarparts throughout the several views.

The bent tube, consisting of the limbs A and B, constitutes an ordinary siphon. The tube 0, with its cap D, piston E, and operating-rod F, when used in connection with the inwardly-opening valve G, constitutes a lifting and forcing pump.

At H is a foot-valve case, having attached at its upper extremity in any suitable manner the short limb A of the siphon A B, and the pump before named by means of its connecting-tube I. The plug J is removably connected with the case H, preferably by means of a screw-thread K, in order that the valve G may be readily removed for adjusting and repairing.

L is a common inlet to the said pump and siphon.

Operation: The case H of the instrument, with its parts in position as shown in Fig. 1, is to be placed in the liquid to be drawn to a depth somewhat greater than to the line M, and preferably sufficient to submerge the entire case 1-1, the pist011-r0d F being drawn upward to or approaching the position shown in Fig. 2, the resulting vacuum causing the atmospheric pressure to open the valve G, as shown in Fig. 2, which opening is followed by ingress of the immersing liquid to the tubes 0 and Lwhen a second and downward movement of said piston-rod F to or approaching the position of said F in Fig. 1 results in closing the valve G, as shown in Fig. 1, and in forcing the contained liquid into and through the siphon A B, and in starting its flow. Should one such series of movements of said piston-rod not prove sufficient to start said flow, said movements may be repeated until the desired flow results.

Having described our invention, we do not claim, broadly, a siphon of any form as a means of decantation, nor, broadly, a pump of any variety as a means of starting the flow of a siphon; but

What We do claim as our invention, and desire to secure by Letters Patent, is-

1. A case connecting with which is the inlet-limb of a siphon and the inlet and outlet passage-way of a suction and forcing pump, the said inlet-limb of the siphon and the said inlet and outlet extremity of said pump having one common inlet-valved entrance, which en rance is adapted to be opened by the exha isting action of a piston-head in said pump am olosedby the ejecting action of said piston in said pun1p,by which means the said pump mechanism is adapted to discharge its contents into the inlet end of the siphon, substantially as described.

2. A valveless pump-tube and a mlveless siphon-tube, in combination with a piston-rod and piston and a chambered ease, the said chamber in said case being adapted to serve as a connecting passage-way between the interior passageways of the said tube and siphon and the said ease having an inwardlyopening valve adapted to serve as a common entrance-valve to the interior passage-ways of said pump-tube and siphon, substantially as shown and described.

In testimony whereof We affix our signatures in presence of two witnesses.
