Specification of Letters 1atent.

Application filed February 8, 1916. 7 Serial No.

To all whom it may concern:

tainers; and we Be it known that we, LOUIS R. Hnrr'z and LOUIS T. Hnrrz, citizens of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Devices for Emptying Liquid-Condo hereby declare the following to be a full, clear, and exact descrip- 1 tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for emptying tanks or barrels filled with oil, gasolene or other liquid, by forcing air into the barrel or container in such manner as to create a pressure that Will'drive the liquid contents of the container out and into an .automobile tank or other vessel adapted to receive the same.

The objects ofthe invention are to provide an improved device of the character re- 7 ferred to, especially designed for use in fillbod mg the tanks of automobiles with g'asolene by forcing the same from a wood or steel barrel or container by air pressure, together with means for regulating and automatically relieving the pressure of the air within the raised sufiiciently or injure the conbarrel or container when high to be liable to burst taining vessel.

e invention will first be hereinafter more particularly described, with reference to the accompanying .drawing, which forms a part of this specification, and then pointed out in the claims at the end of the descript1on.

Insaid drawing, we have shown a side elevation, partly in section, of a device emying a preferred form of our invention, showing the same applied to a barrel filled with gasolene to beemptied in filling automobile tanks or other vessels.

Referring to said drawing, the letter A denotes an inverted L-shaped-plpe extending from within the barrel or container B to a suitable height and having its free end bent into position for the barrel or conan automobile or The letter C may casting provided or turned downwardly emptying the contents of tainer into the tank of other vessel to be filled. denote a tubular member or with a smoothbore extending substantially pipeis adapt-- its entire length in whlch the ed to snugly fit whereby it can be revolublyand, longitudinally adjusted flexible tube 1 I communicates with a similar duct of in communication duct leading to the interior of the container varied andis held in of greater or less density.

such adjusted position. The casting preferably has an exteriorly tapered screw-threaded portion 0 tapped through the barrel or prevent leakage of air or liquid within the container. The casting C has lateral arms 0 and c the rec ends of which are preferably reduced in size'and screw threaded to permit an interiorly threaded tubular part to be screwed thereon. In this instance, a is screwed on the arm 0 for connection with an air compressed air, while a tubular part or cap is screwed on the other arm 0 Each arm 0 and chas an air duct therethrough which 0 leading into the container. Inernptying heavy liquids, which runislowl or container is liable to burst when theair is first turned on, or afterward, under excessive pressure,-unless the operation is carefully watched and the pressure so regulated as to keep it below the bursting point, and to pump, or a source of the barrel in the part ful watching the tubular part or cap E is provided with an air vent e in'the endtherethrough the casting and othersuitable spring F and. ormally valve G agalnst a valve the arm a container; event of the'pressure within the rising too high and tending to burst or injure the container, the spring F will yield and allow the valve G to open and permit the air to escape, thus automatically relieving the pressure when too high. The pressure required to open the valve by screwing the cap E to the'right or left, thereby varying the tension of the but in the spring F to adapt it to press more or less tightly against the ball or other valve, as may e desirable in. emptying barrels or tanks filled with liquids of different kinds or hold a' ball or othersuitable; seat at the end of. so as to normally close the air may be' with the air ductcontains a coiled, 012. arranged to pre'ssflt;

It will be understood, of course, that our invention is not limited in its application to emptying barrels or vessels containing gasolene or .oil, but may be used for various other purposes, in emptying the liqui'd'con- Kinds of vessels and filling vessels of various kinds.

'lo facilitate the entrance of the liquid end of the discharge pipe, and

intd the inlet 'to 4 prevent said end from being closed by v, contact with ably cut away on we claimas new and the bottom of the,liquid container, the lower end of. said pipe is preferat a, to provide suitable feet for supporting said inlet end above the bottom of the barrel or other vessel to beemptied.

Having thus described our invention, what desire to secure by Letters Patent of the United States is:

l. A device for emptying liquid containan upward pull until may be pumped or opposite ,sides thereof, as

insane-7 ers comprisinga tubular body adapted for insertion in a hole in the conta1ner,said body havin a smooth bore extending substantially its'entire length and laterally projecting'arms' each having an air duct therethrough in communication with an air duct in said body extending to its lower end, one of said arms being adapted for the attachment thereto of a tube through which air may be forced into the container and the other arm provided with a safety valve controlling the escape of air through the air duct therein, together with a revoluble and longitudinally adjustable discharge pipe extending through said smooth bore and closely fitting adjusted position and means on the upper end of said body for confining and compressing packing material around said pipe.

2. A device for emptying liquid containers comprising a tubular casting having integral lateral arms and a smooth bore extending substantially its entire length, a discharge pipe extending snugly through said bore into the container and revolubly and longitudinally adjustable therein, one arm being adapted for connection to a source of pressure, a tubular housing detachably connected to the other arm, and a "springpressed valve inclosed in said housing, each duct therethrou'gh, the

arm having an air casting being also provided intermediate its inner and outer. walls with a longitudinal duct opening at the end of the casting and arranged to connect with the air ducts in the arms, and-means on the upper end of sald bodyv for confining and compressing packing material around said pipe.-

In testlmony whereof we aflix our signae tures in the presence of two witnesses.
