INJURIOUS INSECTS OF 1904. 



Cylindrical Metal Spouts: 



L. C. Schroeder of Olean, N. Y., has invented 

 and patented a metal spout, shown in Fig. 12, 

 which is reported as giving satisfaction, since it 

 presents a smooth surface within, and no corners, 

 thus being a great improvement, as regards the 

 flour moth, over the wooden spouts which afford 

 such an excellent opportunity for the larvae and the 

 laying of eggs. It is claimed that the metal spouts 

 cost less than those made of wood. This principle, 

 for reasons which will at once be obvious to prac- 

 tical mill men, cannot well be applied to the ele- 

 vator legs, although it is said that the same party 

 has patented a metal elevator leg. 



Belt Brushes: 



Since metal ele,vators cannot be economically 

 introduced into our mills as they are now con- 

 structed, an excellent device for keeping the wood- 

 en elevators clean, if we are to believe statements 



of those who have used them, consists of an elevator brush as 



shown in Fig. 13, constructed as follows: 

 "To make the brush, take a piece 



of I 1/2-inch plank of the same dimen- 

 sions as the elevator cups, and fasten 



bristles to three sides. The side A 



is fastened to the elevator belt with 



flat-headed bolts running through the 



plank, as shown at B, B, the bolts jj 



being 1/4 or 3/8 of an inch. The bris- 

 tles on the sides C, C should be 3/4 



of an inch long, but those at D should 



be longer, so that they will give a 



good brushing to the outer side of the 



elevator. The brush is easily made, 



and the miller can make it of any size 



to fit his elevators."
