328 CLEAN MILK 



cement finish, boarded inside with planed, matched boards (walls and 

 ceiling), painted white and ventilated after the King system. The 

 space between the inner and outer layer of the walls is stuffed with 

 sawdust and the rooms are very high-studded (fourteen feet). The 

 sterilizer (S) is wholly of concrete, which is described on p. 127, and, 

 if the buildings had not been already built before they were put to 

 their present use, it is probable that the most convenient place for the 

 sterilizer would have been in the wall between the wash and milk 

 rooms, as in Mr. Farrell's (Figs. 82 and 83). The sterilizer is supplied 

 with steam from the 20-horse power boiler (6) in the wash room. 



This sterilizer is an original feature introduced by Mr. Paulhamus. 

 and works beautifully. It is of enormous size (see p. 127 and Fig. 88) 

 and very inexpensive, costing some $80. In cold climates it would have 

 to be inside the building as suggested above. Another novel feature is 

 the washing machine shown as (No. 1 2) in the sketch in the wash room. 

 This was patented after its introduction at Mr. Paulhamus's farm and 

 now sold by. The Chas. H. Lilly Co., of Seattle. The machine con- 

 sists of four tanks, a, b, and c, d and e. In a, is held warm water, in 

 b and c, is contained alkali and warm water, and in d, is plain warm 

 water. The three lines (g) running lengthwise in the sketch, through 

 the middle of the machine, represent three pipes running over the top 

 of the tanks. These pipes are perforated with holes which are placed 

 so as to correspond with the opening in each milk bottle when the 

 bottles are inverted on wooden trays. Each wooden tray is made of 

 slats which, in crossing, leave holes fitting the neck of an inverted milk 

 bottle. The trays holds twenty-four bottles in three rows, so that 

 when the tray is slid in place on top of the machine, each row of bot- 

 tles is- over one. of the three pipes in the centre of the machine, and 

 each bottle is inverted over one of -the perforations in the pipes. On 

 one side of -the. machine, are three rotary pumps (/) worked by the 

 engine at (7). These continually pump water from the tanks into the 

 the pipes, from which it is forced out in jets into the interior of each 

 inverted milk bottle. The water then runs out of the bottles back 

 into the tank over which the bottles are resting. The pipe shown on 

 either side of the top of the machine at (//) is perforated with holes 

 from which water is thrown over and cleans the outside of the bottles 

 as they are pushed through the machine.
