IMPROVEMENT IN PILL-MACHINES.

Speciiication forming part of Letters Patent No. 110,630, dated January 3, 1871.

To all whom it may concer/1L:

Be it known that I, PIERRE CAUHAP, ot' the city of New York, in the county and State ot' New York, have invented a new and useful Improvement in the Manufacture of Iills and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled i-n the art to .make and use the same, reference being had to the accompanying drawing, forming part ot this specification.

This invention relates to improvements in Athe manufacture of-pills; and it consists in the'employinent, either in a combination with a molding' device for shaping pills, or other holder fortheni, of a comb-bar with pins or needles, adapted for inserting a pin in each mold-cavity for taking the pills and dipping them in the coating-solution, and a clamp and stripper for taking them from the needles and redipping them, for filling and covering the cavities formed by the pins, all as herein after described.

Figure l is a transverse section of the mold and the device for taking them therefrom. Fig. 2 is a side view of the device for taking the pills from the mold and dipping them; also a sectional view of the bath, showing the manner of dipping them. Fig. 3 is a perspective view oi" the clamp, stripper, and the device for taking them from the mold, showing the manner of stripping them. Fig. 4 is a side elevation ofthe clamp; and Fig. 5 is a face view ofthe saine.

Similar letters ot' reference indicate corresponding parts.

rIhe pills are to be formed in a mold or bask, A, composed of two parts, either hinged together or not, each having a part ofthe cavities, of which there may be any convenient number, and from each cavity a groove extends' to one side, so that where the two parts ot' the mold are closed together a pin may be thrust into the pill for removing` and holding it, and in connection with 'this mold a comb-bar, B, is used, having as many pins or needles, C, as there are cavities, projecting from it, the same distance apart as the cavities, for inserting into said cavities and taking the pills therefrom. The mold is then opened, the pills removed on the pins, and inserted in the bath of glycerine or other substance with which they are to be coated.

Then for holding and redipping the pills,

to 4lill and cover the cavities left bythe withdrawal ot' the pins, I use a clamp composed'- ofthe two bars E hinged together, as sho-wn in Fig-3, and the elastic frictional strips F of india-rubber or other -like substance, the latter being placed.on the faces of the saidbars, which come together, when closed, over cavities G made considerably larger than the pills, and opening out through the frontedges ot' said hinged bars, as clearly shown in Figs. 3 and 5,'in which the pills are inserted by opening the cla-nip, presenting them thereto coincident with the cavities, while on the pins, and drawing the latter back over the vstripping-bar H, placed in front of thc clamp,

and having' the small grooves Iin the upper surface, placed in front oi' the cavities, t'or guiding the pins of the comb-bar .in placing the pills in the clamp.

The pills are held by the soft, lexible, andA elastic strips F, so that the ends having the holes project, as shown in Fig. 4, and .may be dipped to cover and ll the holes, and th'en be discharged by opening the clamps.

In practice, the molds, comb-bar, clamp, and stripper may be made in any convenient length, and with any preferred number of holes best calculated to effect a rapid operation, and any number of sets of apparatus may be used in case it may be required to retain the pills on the pins, or in the clamp for drying the substance with which they are coated.

'Ihe pills may be taken on the comb-bar while in any suitable holder, at'ter having' been formed in other molds, and I propose to use it in this way, it' found advisable.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the comb-bar B, clamp E, and strippers II, substantially in' thenn'tnner described, and for the purpose specified.

2. The combination of the' moldsA with the comb-bar I3, substantially as and for the purpose specified.

The above specification ot' my invention' signed by me this 2d day ot' November, 1870 GEO. W. MABEE, T. B. MosrrER,
