SUMMARY OF CURRENT RESEARCHES RELATING TO 



I A, M C, L F, K B. All these parts are cast in one piece. To the 

 supporting pillurs two rails are screwed in on the long side, G I and 

 M K, :uid which seen in transverse section show acute angled grooves 

 a li c, in which the knife-carrier fits. One of these grooves def, g h i 

 is planed out 5 to 7 mm. more to render it able to receive the carrier. 



Fig. 184. 



The interspace is filled up with a steel plate edghi, which, though 

 movable on three pivots k I m, is fastened to the groove, and by five 

 screws n op q r on the outside can be fixed more or less tightly to the 

 slide, whereby any irregular movement due to wear is prevented. 



The sliding knife-carrier N O P Q is a frame 12 cm. long and 

 14 cm. broad ; in both cross pieces (Q P and NO) is a slit for the 

 binding-screws which clamp the knife to the under side of the 

 carrier ; by this arrangement the angle of the knife to the object can 

 be altered at pleasure. To introduce the knife it is necessary that 

 the under side of the carrier, the surface s a fi y, should be 1 • 3 cm.
