SIPHON-PUMP SPECIFICATION forming part of Letters Patent No. 503,232, dated August 15, 1893.

Application led February 23, 1893. Serial No. 463,391- (No model.) Y v T0 all whom it may concern:

Be it known that I, EDWARD A. FRANKLIN, a citizen of the United States, residing at Austin,in the county of Travis and State of Texas, have invented a new and useful Siphon-Pump for Oil-Cans and Transfer of other Liquids, of which the following is a specification.

The invention relates to improvements in siphons.

The object of the present invention is to provide a simple and inexpensive siphon for transferring liquid from one receptacle into another adapted to be readily applied to the ordinary oil can, and capable of enabling a liquid to be transferred from a reservoir to a receptacle without liability of spilling any of the liquid and of returning the latter to the reservoir when desired. v

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a sectional view of a siphon constructed in accordance with this invention and applied to a can, the rubber section or leg of the Siphon being shown in full lines in position for filling a lamp, and in dotted lines in an elevated position for emptying a lamp and transferring the contents back to the can. Fig. 2 is a detail perspective view of the lower head of the cylinder. Fig. 3 is a reverse plan view of the same.

Like numerals of reference indicate corresponding parts in all the figures of the drawlngs.

1 designates a metallic tube forming the short leg of a siphon and having its upper end connected detachably with a flexible leg 2 of rubber or other suitable material, adapted to have its lower endreadily constricted by squeezing with the fingers to enable it to be readily transferred from one lamp or othervessel to another, and adapted to be elevated, as illustrated in dotted lines in Fig. 1 of the ac-I companying drawings to transfer the contents or a portion of the contents, in case a lamp is.

filled too full, back to the reservoir or can 3. The upper end of the rigid metallic tube or pipe 1 is curved outward, and is secured below the curved portion to a screw cap 4 of the oil can. The lower end of the rigid tube 1 is secured to and communicates with a short cylinder 5, which is considerably shorter than the tube 1 and is adapted to be arranged in the oil can considerably below the top or cap to avoid any liability of the liquid being forced out of the can at the screw cap through leakage by the upstroke of a piston rod 6, as would be the case were the pump cylinder the same length as the tube 1 and terminated at the screw-cap. The top of the cylinder is connected with the screw cap by a brace 7 and is arranged close to and parallel with the tube 1, whereby the vcombined diameter of the cylinder and the tube may be readily made less than the diameter of the ordinary oil can screw-cap, in order that the siphon may be readily applied to any ordinary oil can and inserted through its opening.

The piston-rod 6 extends through a perforation of the screw-cap, terminates at its upper end in a handle and is provided at its` lower end with a piston 8,wliich when raised creates a vacuuml in lower end of cylinder 5. This vacuum immediately fills with liquid from the receptacle through the valve opening 11. The downward stroke of the piston 8 closes the valve 12 and liquid is forced through the opening in the cylinder, into the lower end of the tube`1, One stroke of the piston will in most cases start the flow of liquid through the siphon, after which the ow will be continuous without the use of the pump as will be readily understood.

The oil or other liquid enters the cylinder through a valve which opens inwardly, and a'perforation 9 which-*relieves the pressure on the valve and which when the flexible leg of the siphon is raised above the oil can permits the oil to iiow back into the can. The lower cylinder head has an annular flange 10, which is secured to the body of the cylinder, and it is provided with a valve opening 11 and has secured to its upper face a flexible disk 12 of leather, which forms with the opening 11 the valve. The flexible valve disk 12 is secured to the cylinder head by tongues 13 formed integral with the cylinder head and bent downward on the upper face of the disk 12, the latter closing the openings formed by cutting the metal to provide the tongues.


It will be seen that the siphon is simple and comparatively inexpensive in construct-ion and is adapted to be readily applied to the ordinary oil can, and that it is capable of readily transferring a liquid from one receptacle to another and back again. It will also be apparent that in filling lamps, should too great a supply of oil be transferred to a lamp, a por tion may be readily returned to the receptacle.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrilieing any of the advantages of this invention.

What I claim isl. The combination with a receptacle, of a siphon having a rigid leg arranged in the receptacle and an outer iiexible leg, a cylinder shorter than the rigid leg of the Siphon and located below the top, a screw-cap secured to the rigid leg of the si phon near the upper end thereof,a brace having its upper end secured to the screw cap and its lower end fastened to the cylinder, a piston rod passing through the screw cap and extending into the cylinder, and a piston secured to the piston rod, substantially as described.

2. The combination with a Siphon, of a pump having its cylinder communicating with the siphon and provided in its lower cylinder head with a valve opening and having integral tongues, and a iiexible valve disk arranged over the valve opening and secured beneath the tongues, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
