    Stocker's Improvements in Infants' Feeding Bottles, Sfc. A.D. 1807, and I proceed as follows :—-When I have these caps or covers produced in any manner now well known and of desirable depth and diameter and in their blank or unscrewed state, I place them in dies which have screwed holes therein of a measurement both in depth and diameter desirable for the intended screw to he given to the cap or 5 cover when operated upon; I then place in the cap or cover a mandril or plug of india-rubber fitting or nearly so the orifice of the die and somewhat higher than it; I then place them together into a turned box permanently fixed in a fly press; I then by the aid of a flat blank forcer or plunger give the rubber a smart blow which screws the cap or 10 cover, the die is then lifted out of the box, when the cap or cover may be readily released, the * die again charged with another blank and the rubber, and so on the operation repeated. I use a series of these dies following each other for the purpose of despatch. Each die is accurately although loosely fitted into the permanent box so that when 15 one has been used another is placed by hand therein immediately, and so on they follow in rotations. Caps or covers composed of metal of this category may be made and screwed other than in the manner I have mentioned without departure from my Invention, but I prefer this mode of procedure on account of economy and good workmanship. When 20 these caps or covers are applied to and employed with infants’ feeding bottles central holes are made in their crowns or centres for the passage of and holding therein the infant’s ordinary sucking tubes, as well also of holding, combining, and employing therewith discs made according to my Invention of india-rubber, substantially as and for the purposes 25 described in the Specification of my Patent, No. 675, A.D. 1868. This rubber is before being cut into discs prepared or treated according to my Invention in the following manner :—I pass it one or more times through or between a pair of rollers, one of which is rigid on its surface and provided with sharp pointed pins or spikes fixed therein of suitable 30 lengths and diameter and at proper distances apart, whilst the surface of the other roller is rendered elastic by coating it with plain rubber or other suitable soft material. The sheet after having been operated upon will assume a porous-like texture; it is then to be cut at one operation into discs having desirable holes in the centre for the purpose of holding 35 therein and employing therewith the sucking tubes before mentioned. These discs may be cut out by any of the well-known appliances at present in use. If desired the sheet of rubber may be similarly punctured by the aid of piercing tools worked in any convenient manner
