For this purpose, a sleeve 33 of the several features of themvention, insulating material, Such as Bakelite or 1 Is an elevatlon wlth parts broken away canite, of diameter considerably larger than that showing the draft e pp t a keg f use of the draft tube, is rested at its lower endu h 50' a in the installation and method of the parent apa bushing 34 fast on th lower d f an upper" plication, section 16' of the draft tube, to which it may be Fig. 2 is a view in longitudinal cross section cemented.

A metal bushing 36 is screwed at 31 upon the upper end of the draft tube section [6' and exerts pressure against the upper end of sleeve 33 to which it is preferably also cemented. Into the bushing 36 is screwed the stud 38 of the faucet F. Preferably a double ply fine mesh Monel metal filter screen 39 is placed between the shoulder 4-9 of bushing 36 and the bottom of the faucet F and serves as a guard to intercept any loosened chip, scale or the like that might be entrained by the beer from the barrel.

It is, of course, understood that the draft tube I6 might be made in one continuous piece, but the sectioned construction shown is preferred as it facilitates disassembly for cleaning and also facilitates economical replacement of any small section or fitting that has become injured.

The faucet in general outline may be substantially conventional. It comprises a casing 4| rising from the mounting stud 38 having a chamber 42 with a sliding valve 43, the axial shank or stem 44 of which is guided at its rear end in bearing 45 and carries at its forward end adjacent the valve a perforated-guide collar 45 said valve operated by the lower end 4'! of the operating lever, extending into a corresponding slot 48 in the stem 44, the lever being pivoted to the casing as at 49 and having an upstanding handle 50. The valve has a spherical seating head 5! of rubber, pressed to closed position against a spherical valve seat 52 at the inner end of the valve nozzle piece 53 assembled to casing 4| by means of a union nut 54.

The passage from the valve seat through the mounting stud of the faucet, extends longitudinally downward at shank 55, continuously from the valve seat to the lower stud extremity. Similarly the wall 56 of the nozzle 53 extends continuously downward in its longitudinal direction from the valve seat 52 to the spout. The middle portion of the faucet lodging the valve guide 46 extends horizontally. The trough or lower portions of the faucet passages thus serve as gutters completely and promptly to drain any remnant of brew therefrom, without possibility of brew remaining lodged or trapped therein.

The draft equipment described and claimed imposes a low resistance to the flow of the brew which renders it especially useful in the system and method as specifically described in the parent case, in which the gas pressure supplied to the U brew of the barrel is substantially lower than the equilibrium pressure of the gas dissolved in the brew and in fact is of magnitude but little great er than that required-to elevate the brew from the bottom of the draft tube to the faucet near the head of the barrel. Under such low pressure and with the use-of the low resistance draft tube,

Beer draft equipment, comprising a draft tube section, a flanged bushing thereabout near the lower end thereof, a second flanged bushing at the extreme upper end of said tube section, an insulating sleeve encircling said bushings, abutting the flanges thereof and spaced from said draft tube section to afford an insulating air space therebetween for protection of said draft tube from sweating at the otherwise exposed portion thereof, a second tube section, means cooperating with said first bushing to effect union between the two tube sections, anda faucet connected to the upper end of said first tube section.
