Application September 26, 1935, lSerial No. 42,205 3 Claims. (Cl. 225-3) This invention relates to means for drawing beer from barrels, kegs or the like, and is partic pipe 'I for supplying air orgas under pressure to the interior of the barrel. The tap also has va ularlyintended as an adapter or attachment to be used in connection with beer tapsor as a part " '5 of such taps. Taps are well known and aremade locking nut 8 for attaching it to the barrel fitting inra variety of forms. 'I‘hey provide means for " admitting air or gas under pressure to the barrel for forcing out thebeer or other liquid and also provide means for inserting a >tube or pipe com monly, known vasa r“tapl rod orV tube” intoV the fbarrel .for lwithdrawing the _beer therefrom, .such tubev ¿being usually connected ywith a pipe or hose leading to thecooler. 'I‘he pipes or conduits lead n ing from the beer barrel, including vthe cooling 10Vcoils, shouldbe Vfrequently,cleaned in order to providegood clean beer. It is possible to vclean thecoils even whenv the beer-.barrel isA under pres sure, by shutting 01T vthe tap rod valve and dis connecting .the„hos,e. therefrom. Consequently . zocthisis `often .done and the tap rod `is left without îcleaning for„indei_ini_te,„_ periods. In accordance with the, present invention I provide means '-25 and is provided with a threaded portion 9 for', Y receiving a packing washer or gasket I0 and nut:-` 6 or gland II having a handle I2 for turning the same. n The tap rod or tube I3 ordinarily extends downwardly through the tap to approximately,i s the bottom of the barrel when the tap is in oper- 10 ative position anda tight closure> or connection is made between the upper end 9 of the tap and the rod by vmeans of the gland _and packing I0. In accordance with my invention I provide ~am valve body or fitting’ I4 ,which is threaded at I5 'to‘ 15 engage with the threaded upper end 9 ¿of the> tap. The upper end of the valve or adapter body yI4 is recessed at It to receive the packing Ill-and is provided with a. shoulder I'I for engagement „with the packing. The upper end yis also .threaded at~20 I8 tov receive the Vmit or. gland II as readily4 seen whereby the tap rod or tube may be inserted into therbarrelor withdrawn therefrom when the bar from Figure 1. When my adapter is appliedto theusual tapk the packing or washer >I0 .andnut II are removed from the tapand _placed inthe rel is under pressure, without losing the pressure upper end of the body as shown. or permitting the discharge of any appreciable amount of the contents of the barrel. The objects ofV this invention are to provide an The tap rod I3 may then be inserted through the valve body I4 and the tap and into the barrel in the usual manner and the packing be tightened in order to prevent any leakage around the rod. improved adapter or device for accomplishing the 30 above purposes in a simple and eñicient manner; to provide an adapter or attachment which may be readily applied to beer taps such as are now l in Vcommon use which may becheaply made and which will be eñîcient in permitting the insertion 35 and Withdrawal of the tap rod without losing pressure; to provideV a beer tap- adapter for the purposes set forth which will have comparatively few parts and which will have a relatively smooth and unobstructed interior so that bacteria will 40 not be apt to collect therein andalso so that the device may be readily cleaned or sterilized and to provide such other advantages and improve ments as will appear more fully hereinafter. ' 25 In order to prevent discharge of gas or liquid A30 from the barrel, the valve body has a valve seat I9 at the top thereof which is adapted to be en gaged by a ball 20 when the valve rod is removed. The ball 20 may be made of cork rubber, rubber ¿composition or any other suitable material, pref- 35 erably of a light and yielding character so that it may be readily forced against the seat I9 by the gas pressure. The valve body I4 has a lateral projection 22 which forms a side chamber or recess for receiv- 40 ing the ball 20 when it is out of closing position. Curved side rails or guides 2l serve to guide the ball from its closing position as shown in Figure 2, to its normal or inoperativeposition as shown in Figure 1. The projection 22 is threaded to 45 In the accompanying drawing illustrating a commercial form of my invention, Figure 1 is a side view showing a barrel and ' receive a plug 23 to close the opening through tap with my adapter applied thereto, parts being which the ball or valveV 20 may be inserted and shown in section; - Figure 2 is a side view showing the parts in pov G sition after the tap rod has been removed; and Figure 3 is a sectional view taken on the line 3-3 of FigureV 1. 'I‘he barrel 4 is shown with a tap 5 of any ordi nary or preferred form of construction, this tap 5 u having the usual side connection 6 and hose or removed as for cleaning or the like. When the keg 4 is tapped and the tap rod I3 inserted in theusual manner the packing I0 is 50 tightened andV air or gas under pressure may be admitted through the supply pipe or hose 1, thus placing pressure on the contents of the barrel. The beer or other contents of the barrel may then be drawn 01T through the tap rod and out through 55 2 2,099,528 the pipe 25 being controlled by the valve 24. When it is desired to clean the tap rod or con duits connected therewith, the packing may be loosened and the rod withdrawn and ther-eupon the pressure on the ball or valve 2Q will cause it viding a recess for a valve ball said recess being open at the outer end thereof, means for closing the outer end of the recess, a valve seat at the upper end of the bore through said ñtting, a valve ball in said fitting, and integrally formed curved to move up the guideway and engage with the guide members for guiding the ball from its nor seat I9, thus immediately closing the outlet of the mal inactive position in said recess to the valve seat when the ball is moved upwardly by gas pressure, the arrangement being such that the barrel and preventing the escape of gas or pres sure. In order to insure the upward movement 10 of the ball when the rod is removed, it will be noted that the bore through the fitting is made but little larger than the rod so that the gas en ball may be readily removed for cleaning or re placement without removing the tube from the ñtting. tering at the bottom of the bore will immediately strike or act upon the ball 20 to force the same 15 upwardly against the valve seat. In actual prac tice I have found that the valve will close with 2.
