Lnmley's Improved lDill Machine. the standards; the axis d has cam-shaped pieces 4 fixed thereon, the pieces 4 taking into the straps N, as at Figure 4, raise and lower the straps N and knife k connected thereto, as at 5, by its ends. The shape of this knife is shewn at Figure 11. O is a curved 5 piece of metal with grooves formed on its inner surface and with pivots Z, Z, as shewn at Figure 10, which take into holes in the standards B; and P is an adjusting screw passing through a screwed hole in the piece ?n, which is pivoted by its ends in holes in the standards B. The use of the screw P is to cause the spring 6 to 10 press slightly against the piece O. Q are screws and nuts for raising and lowering the hearings a, so as to adjust the cylinder C at any desired distance from the cylinder D to prevent the complete separation of the prepared sheet of ingredients as it passes between them. The fly wheel H has a handle at It fixed into one of its arms 15 for imparting rotatory motion to the several parts of the machine. The boss of the fly wheel fits on to a square formed on the outside of the boss 7 of the wheel L, which boss is formed on the said wheel, as at Figure 6, and the hole through the centre of the boss 7 fits loosely upon the axis 1 of the wheel D as before stated; S is a table to receive the 20 sheet of ingredients from which the pills are to he made. Operations oe the Machine. The prepared sheet of ingredients being pressed against the cylinders C, D, upon motion being imparted to the wheel II these cylinders will receive rotatory motion through the medium of the wheels I 25 and L, studs i and c, and wheels G and b} b, thereby advancing the sheet between the said cylinders and squeezing or rolling it into the shape exhibited at Figure 8 in cross section, and by the time the edge of the sheet has reached the cylinder E the knife k by the action of the cams 4 on the straps N will descend and cut or divide the sheet, as 30 denoted by the dotted line at Figure 9, and the piece thus cut off will he taken hold of and drawn between the cylinder E and piece O, which will have the effect of entirely dividing or cutting the strip across, leaving each piece in its respective grooves in the cylinder E and piece O, and by this time the teeth of the wheel L being out of gear 35 with the teeth of the wheel I the cylinder E will he moved in an opposite direction by the studs i coming against the lever g and lifting the piece K, thus turning the cylinder E partly round in an opposite direction, and when this stud comes into contact with the part 2 of
