    Newtons Improved Apparatus for Manufacturing Capsules. next and immediately after the date of the said in part recited Letters Patent, as in and by the same, reference being thereunto had, will more fully and at large appear. NOW KNOW YE, that in compliance with the said proviso, I, the said William Edward Newton, do hereby declare that the nature of the said 5 Invention, and the manner in which the same is to be performed, is par¬ ticularly described and ascertained in and by the following description thereof, reference being had to the Drawing hereunto annexed, and to the letters and figures marked thereon (that is to say) The improved instrument which forms the subject of the above in part 10 recited Letters Patent consists of the following parts, which are represented in the accompanying Drawing at Figures 1, 2, 3, and 4, the latter of which is a vertical section taken diagonally through Figure 1 at 2, when the parts have been all combined. In Figure 1, A represents a plate of metal or hard wood, which may be 15 about three eighths of an inch in thickness, and of any suitable form, pierced with round holes of any convenient size according to the size of the capsule required to be produced. These holes are made at equal distances apart, and their edges rise some extent above the body of the plate so as to present the appearance of a number of tubes. There is a rim or ridge a, a, a, round 20 this plate of any suitable width, say from a quarter to half an inch. Figure 2 represents a frame B of the same dimensions as the rim of the plate A, and in other respects precisely similar to the rim a, a, a, round the plate A on which it is intended to be applied, and it is provided with guide pieces to attach it to the plate A ; another plate C, shown at Figure 3, and 25 similar in construction to the internal part of the plate A, minus the rim ✓ which surrounds it, is made so as to fit accurately on to it and into the frame B which is placed thereon. The circular holes of this plate must correspond exactly with those of the plate A, and be similar in all its parts except that the plate C is twice the thickness of the former. The following 30 is the method of manufactering capsules with this instrument:—A paste composed of sugar, gum, and a small quantity of honey and gelatine, or any other suitable composition, is spread out into thin sheets. The frame B is then placed bottom upwards, that is to say, with its angular fastenings up¬ wards, and a sheet of the material is laid upon it. The liquid to be enclosed 35 is then poured into the cavity presented by the sheet of gelatinous material of which the capsules are to be formed, and the whole is covered over with another sheet of the gelatinous material, which is wetted at the edges so as to’ cause it to adhere to the under one ; by this means the liquid is
