TAP FOR DRAWING LIQUIDS FROM CASKS, 860.

T 0 (LZZ whom it may concern:

Be it known that we, MIL ON Lemon) and Jon-N BATH, citizens of the United States, residing at Lafayette, county of Montgomery, and State of Pennsylvania, have invented ,a certain new and useful Improvement in Taps for Drawing Liquids from (Tasks, &-c., of which the following is a specitication.

()ur invention relates to new and useful improvements in taps for drawing liquids from casks, etc, and has for its object to pro vide an exceedin ly simple and effective device of this character, which will prevent'the accidental escape of air, or fluid from the barrel or cask, when said barrel or cask tapped.

A furtherobject is to so construct the tap that it can be easily inserted into a barrel or cask without first partially driving the hung with a mallet or other instrument.

A. still further object is to construct a tap. into which the drawing or outlet pipe may be inserted without the danger of permitting any of the air. gas or 'liuid to escape from the barrel or cask.

A still further object is to provide a tap which, should it be desired to withdraw the drawing or outlet pipe before all the liquid has been used from the barrel or cask. it may he done, and in so doing the tap will automatically close, thus preventing any of the air, gas or liquid from escaping.

d. ith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims. 7

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, we will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure l is a longitudinal sectional view of our improved tap. Fig. 2, a plan view thereof. Fig. 3, a section at the line Y-Y of Fig. 1. Figml, a side elevation of the sleeve or ferrule. Fig. 5, a plan view there, of.

of the same, and, Fig. 11, a side elevation showing the relation of the ferrule, ring, valve or stop, and the spiral spring, before being placed in the casing.

In carrying out our invention as here embodied, A. represents the casing or body of the tap, and B the tapered member adapted to be driven into the bung hole of the barrel or cask. On the low-er end of the casing on body A are cut the threads C which are adapted to engage with the threadsD formed on the inner surface of the enlarged upper portion E of the member B. The upper end of the casing is internally threaded as indicated at F, so that the nut G, having the wrench hold H formed therein, may be threaded in the upper end of said casing or body 1- In proximity to the upper end of the casing is formed an internal flange I, between which and the nut G is adapted to rest the elastic packing J. A portion of the inner surface is conical indicated by the reference letter K, and from this surface cut a groove L, in which may be placed a packing M, if so desired.

In the lower portion of the casing A is formed an annular recess N, in which is adapted to fit the flange 0 of the ferrule P, around this ferrule, and resting against the flange thereof, is placed a spiral spring Q, the upper end of which is adapted to rest against the ring R, with which is formed the fastening lugs S, and the adjusting lugs T.

U indicates a valve or stop which is formed of two parts I and U each part having the lugs V formed from the lower ends thereof by which they are pivoted to the fastening lugs S formed on the ring R. Vith the upper end of these parts are formed the curved projections .Y, so that when the drawing or out-let pipe which may be pointed is placed in the tap and rests against the stop or valve, it will be centered between the projections W.

Z represents an inlet formed with the member B, in proximity to its upper end, to which is attached the hose of the air pump, and in the inlet Z is placed a ball Z so as to form a check valve, which will admit air, but will close againstback pressure of air.

In practice, the complete tap as shown in the drawings is driven into the cask or barrel, then the drawing oroutlct pipeis inserted in the upper end of the casing A, passing through the nut G, until it rests PatentedAug. 24:, 1909.

against the top of the stop or valve U, when by exerting a sufiicient amount of pressure on said drawing pipe, it will compel the stop U to be pressed downward against the action of the spring Q and as this is pressed down, the ferrule l will cause the parts U and U of the stop or valve U to follow the angular sides K of the casing A, thus leaving one another, until the drawing pipe will be allowed to pass between these two parts U and U at which time it will pass through the ferrule 1" and the member B into the cask or barrel, and when it has been inserted the desired distance, a wrench may be placed in the wrench hold H, formed in the nut G, then by drawing said nut G down upon the elastic washer J, it will cause said washer to expand sidewise until it fits tight about the drawing pipe, which would prevent air, gas or liquid from passing around said pipe. \Vhen it is desired to withdraw the drawing or out-let pipe, the nut G is loosened so that the washer J will recede from the drawing pipe, which will allow the drawing pipe to be withdrawn. lVhen the end of drawing pipe passes beyond the upper ends of the parts U and U of the stop or valve U, the spring Q will press the ring R to which the valve or stop U is pivoted, upward, and this will cause said valve or stop U to also be pressed upward, and as the sides of the casing are conical the higher the parts of the stop go, the closer they will come together, until they finally meet, which will close the passage. In order that these two parts U and U of the stop U, will be pressed up evenly, or both at the same time, the lugs T are formed with the ring R, which will rest against the bottom portion of the sides of said parts U and U at that point where they meet.

Of course we do not wish to be limited to the exact details of construction here shown as these may be varied within certain limits without departing from the spirit of our invention.

Having thus fully described our invention what we claim as new and useful is 1. In a tap, the combination with a body or casing having internal threads on its upper end, and external threads on its lower end, and a portion of the inner surface con ical in shape, of a ferrule, a ring having lugs formed thereon, adapted to pass around said ferrule, a spiral spring placed about said ferrule, one end of which is adapted to rest against a portion of said ferrule, and the other end against the ring, a valve or stop formed of two parts pivoted to said ring, and adapted to rest against the conical sides of the casing, a tapered member, the upper end of which is enlarged, and has an internal thread formed therewith, adapted to engage with the external threads formed on the body or casing, an air inlet formed in said tapered member, a ball placed therein, thus forming a check valve, an internal flange formed with the upper end of the casing, a nut having a wrench hold formed therewith, adapted to be threaded into the internal threads formed with the casing, and, an elastic packing resting between the internal flange, and the nut, as shown and described.

2. The combination with a body or casing, of a ferrule, having a flange formed therewith, a ring, lugs formed therewith, a spiral spring adapted to pass around the ferrule, one end resting against the flange thereof, the opposite end resting against the lower portion of the ring, a valve or stop formed of two parts pivoted to the ring, a tapered member having an air inlet formed therein, a check valve placed in said air inlet, and means for removably securing the tapered member and the casing together, as specified.

3. In combination, a casing, a portion of which is conical, having an internal thread cut on the upper end, an external thread formed on the lower end thereof, an annular recess formed in the lower end of the casing, a ferrule, a flange formed on said ferrule, said flange adapted to fit within the annular recess, a ring, fastening lugs, and adjusting lugs formed therewith, a spiral spring passing around the ferrule, one end resting against the flange formed therewith, the other engaging the lower portion of the ring, a stop or valve formed of two parts, lugs formed with said parts for pivoting the said parts to the ring, projections formed from the top of the parts of said stop or valve, packing placed in the inner surface of the conical portion of the casing, an in ternal flange formed with the casing, in proximity its upper end, an elastic packing resting on said internal flange, a nut having wrench holds f rmed therein, adapted to press against the elastic packing for expanding it sidewise, a tapered member, the upper portion of which is enlarged, and has an internal thread formed thereon, for engaging with the external thread formed on the easing, an air inlet formed in the tapered memher, and, a ball placed therein, thus forming a check valve, as shown and described.

In testimony whereof, we have hereunto aiiiXed our sigi'iatures in the presence of two subscribing witnesses.
