10 the beer drawn from them and dispensed to customers.

It is an object of this invention to provide a double-walled barrel wherein an inlet and an outlet connection are provided in the outer wall of the barrel head in which the tap bush occurs. Thus I aim to provide a barrel having connections to which inlet and outlet pipes of a water cooling and circulating system may be readily attached, and wherein the barrel connecg tions are so arranged that there is very little "possibility of any water which remains between the walls of the barrel being spilt when the connections are disconnected for removal of the barrel.

2;} Another object of the invention is to provide a double-Walled barrel having inlet and outlet connections provided in the outer wall of one head, and a pipe extending from the inlet connection to substantially the opposite extremity of the barrel, so that the water introduced through the inlet circulates between the barrel walls throughout substantially the entire length of the barrel before returning to the outlet.

A further object of the invention is to provide in transit.

Having thus briefly and broadly stated some Figure 4 is a section on the line 4-4 of Figure 3.

Figure 5 is an enlarged plan view of the inlet connection and the closure therefor.

Figures 6 and '7 are sections on the lines 6-B 5 and |'I respectively of Figure 5.

Figure 8 is an enlarged plan view of the outlet connection and the closure therefor, and

Figure 9 is a section on the line 9-9 of Figure 8. 10

Referring now to Figures 1, 2, and 5 to 9 of the drawings; the outer shell of the barrel consists of two halves 2 and 2a the adjacent annular margins of which terminate contiguous to one another and are welded around the periphery of the inner shell 3 substantially centrally of its length, thereby holding the outer and inner shell portions spaced from one another and in contact only around the central portion of the barrel. Consequently an annular upper and lower chamber 4 and 5 respectively are formed between the shells separated by the circular welded joint 6.

Formed around the outer shell portions 2 and 2a equidistant from the joint 6 are outwardly di rected corrugations I and 1a. Extending between the outer portions of these corrugations and secured thereto around a portion of the circumference of the barrel is a bung plate 8 which is outwardly spaced from the joint 6. The sides 8a of the plate 8 are inwardly flexed and are secured to the outer face of the outer shell portions 2 and 2a and to the joint 6, thereby enclosing an intermediate compartment 9. Formed centrally in the plate 8 and extending through the joint 6 is a conventional bung collar l0; and on each side of the latter beneath the plate 8 the inwardly inclined portions 2b and 2c of the outer shell adjacent the joint 6 are apertured.

A tap bush [2 is provided through both the inner and outer shells of the head l4, and mounted in the outer shell of the same head are inlet and outlet fittings I5 and I6 to receive pipes l1 and I8 respectively of a water circulating system.

In the present instance the inlet fitting I5 is provided at its inner extremity with an angle connection I5a to which a pipe I!) is secured. The latter extends through the upper chamber 4, through the apertures formed through the inwardly inclined portions 2b and 2c of the outer 50 shell, through the intermediate compartment 9,

and terminates towards the bottom of the lower chamber 5. The outlet fitting I6 merely extends through the outer shell of the head [4. Consequently cold water delivered through the pipes I1 I and I9 and the fitting I5 is ejected in the lower chamber 5 near the bottom thereof, and rises therein, through the intermediate chamber 9 and upper chamber 4, and is discharged through the fitting I6 and pipe I8.

It will be noted that the outer extremities of the fittings I 5 and I6 terminate within the chime and only slightly above the head l4, though in Figures 5 to 9 the distance theyproject above the head is exaggerated to more clearly show the preferred forms of closures with which they are equipped.

Secured upon the head I4 is a bracket 20 carrying a hinge pin M on which a closure 22 is pivoted. Around the pin ill a helical spring 23 is provided which tends to retain the closure in shut position, though obviously it may be opened sufficiently for the pipe H to be connected to the fitting l5.

Adjacent the outlet fitting a bracket 24 is mounted upon the head I4 to carry a pin 25 on which a closure 26 is pivoted to cover the mouth of the fitting I6. 2'! denotes a spring by which the closure 26 is held against accidental movement when in closed position.

In the construction shown in Figures 3 and 4, the arrangement is the same as that shown in Figures 1 and 2 except that the outer shell 32 consists of two end portions 32a and an intermediate portion 32b. The latter is provided at both extremities with inturned annular flanges 32c which are suitably secured around the periphery of the inner shell 33. The adjacent ex tremities of the end portions 32a of the outer shell extend annularly over the intermediate outer shell portion 32b to which they are usually welded.

The head 34 in which the tap bush I2 is provided also carries inlet and outlet fittings I5 and I6. From the fitting l 5 the pipe I9 extends downward between the shells 32 and 33, through perforations 32d through the flanges 32c, and terminates towards the lower end of the barrel between the inner and outer shells. Water discharged from the pipe l9 passes upwardly again between the shells, through the flange perforations 32d to the outlet fitting l6.

While in the foregoing the preferred embodiments of the invention have been described and shown, it is understood that further alterations and modifications may be made thereto provided the said alterations and modifications fall within the scope of the appended claims.
