    5 Mennons' Improved Apparatus for the Capsulation of Fluid Medicines. its stationary counterpart C; K, fly wheel, by which the closing apparatus is opened and shut; M, opening pierced through the framework A and table N of the apparatus to give passage to the capsules produced ; T, pipe communi¬ cating with a steam boiler of any convenient form, by means of which the 5 apparatus may be heated to a temperature of about 20 to 25 centigr. (68° to 77° Fahrenheit) ; U, steam chest; Y, purge pipe. Figure 2 represents the arrangement by means of which the strips or bands of plastic matter are prepared for use. 0, 0, is a metallic tablet of any required length; say, for instance, six feet, by four inches in width, provided 10 with edges forming at each side a ridge of about one-fiftieth of an inch in height, corresponding with the thickness to be given to the strip of paste; P is a charnot or slidin^ box, in which is placed the hot plastic matter. In the bottom, and below the front of this box, is cut a narrow oblong slit, correspond¬ ing in length with the width comprised between the ridges of the tablet 0, 0 ; 15 Q, key fixed to the stopper of the slit; R, slide piece worked by a screw S, and serving to gauge the thickness of the paste. The charriot P being charged with the hot plastic matter, the slit is opened by a forward motion of the key Q, allowing the paste to flow along the tablet 0, 0. It is then moved forward to the opposite end of the tablet, at which is formed a cavity Z for 20 the reception of the surplus plastic matter, and the slit being closed by a reverse motion of the key, the same operation is repeated as often as may be required. The bands of paste thus prepared being wound on the bobbins G, G, Fig. 1, their extremities are brought down to the base of the closing appa¬ ratus D, E, previously opened. This apparatus is then shut by aid of the fly 55 wheel K, and in this movement closes off by pressure the edges of the plastic bands, after which it is re-opened to permit of the latter being brought down by the lever I. Ihis operation is repeated four times, the lever being carried up at each shuGofF motion of the closing apparatus. The fly wheel J is then set in action to carry up the free mould plate C1 to its stationary counterpart C, SO and the plastic tube being pressed, its lower extremity is closed to form a species of bag. Ihe fly wheel J being reversed, the tube comes still further down, and the stop-cock L being opened admits thereto the required quantity of fluid. The same fly wheel is then again turned forward, to bring the mould plates again together, and in this motion 25, 30, or 60 capsules, as the case 35 may be, being finally filled, closed, and detached, are carried by the opening M into a drawer placed for their reception below the table of the apparatus. Having now described the nature of the said Invention, and the manner of carrying it into effect, I would have it understood that I do not confine myself to the precise details of form and dimensions above laid down, as these may
