    J. 8f E. Lumley's Improved Fill Machine. Description of the Drawing. V Figure 1 represents an elevation of the front of the machine without the fly wheel; Figure 2, an elevation of the hack of the said machine; Figure 3, a top plan view thereof; Figure 4, a longitudinal and vertical section through the line A, B, at Figure 3; Figures 5 to 12 inclusive 5 represent detached views of parts herein-after particularly described and referred to. At each of the foregoing Figures we employ similar letters of reference to denote corresponding parts in so far as such parts appear or can he seen at each of such said Figures respectively. A, A, marks the stand of the machine, to which are fixed the 10 standards B supporting the following parts or pieces :—C, D, E, are three cylinders having grooves formed around them and axes working in holes, and adjustable hearings a formed in and fitted to the standards B. The cylinders C and D are of the same diameter and have toothed wheels 6, 6, fixed on their respective axes for imparting 15 rotatory motion thereto in opposite directions by means of the stud cy toothed wheel G (fixed on the axis 1), and fly wheel H, as hereafter described. The stud c is fixed on one end of the axis d of the cylinder E, and upon the opposite end of the axis d a toothed wheel I is fixed, into which a pin e is fixed which takes into a 20 hole formed in a piece of metal K connected at its upper end to a pin f fixed in one end of a short lever g, whose fulcrum is a pin or screw at h fixed in the standard B. The opposite end of this lever is acted upon by studs i fixed in a wheel L; this wheel works loosely upon the axis 1, and has teeth formed upon its edge, as at Figures 1 25 and 5, the studs i in the wheel L coming into contact with the lever g and part 2 of the piece K produce alternate circular move¬ ment of the cylinder E after the teeth in the wheel L have become disengaged from the teeth of the wheel I, as shewn at Figures 1 and 5, the wheel L being moved in the direction denoted by the 30 arrow’s flight. At these Figures M marks a double comb, shewn detached at Figure 12. This comb is held in position by the standards B, and is intended to take into the grooves of the cylinders C, D, to prevent clogging thereof with the ingredients of which the pills are to he made; N is a strap of metal pivoted by a pin 3 fixed 35 in a recess formed in the standard B. The opposite standard is also similarly fitted so as to leave the straps N flush with the face of
