VOLUME OF LOAF APPARATUS 



Two aluminum receptacles, connected 

 with a graduated tube, are suitably 

 mounted on a pedestal and pivoted in 

 the center for reversing the alternate 

 ends. A funnel orifice in the center 

 of the tubing causes the seed to 

 flow uniformly from the top to the 

 bottom receptacle like an hour-glass. 

 This mechanical filling of the lower 

 receptacle insures the same degree of 

 compactness under all conditions, 

 therefore, machine accuracy. To 

 operate the measure, the lid of the 

 top receptacle is removed, mustard 

 seed is poured in until the standard 

 quantity is registered. The loaf is 

 secured to the top lid by a spring 

 clamp; the lid is then replaced and 

 the position of the two receptacles 

 reversed; the seed flowing through 

 the orifice in the center of the tubing 

 fills in around the loaf in the bottom 

 receptacle. The amount of seed dis- 

 placed registers the volume of the 

 loaf on the tubing, graduated in 

 cubic centimeters. The operation is 

 repeated \v ; lh additional loaves, using 

 the alternate receptacles. The recep- 

 tacles are made to accommodate the 

 regular commercial pound loaf.
