Making Extracts.

- ra n STA s BENJN BRANDRETH, OF NEW YORK. N. Y.
"MAKING VEGETABLE EXTRACTS.
T all whom, it may concern I Be it known that I, BENJAMIN BRANDRETH, ofthe city and Stateof New York, doctor of medicine, have discovered a newand' useful: Improvement in the Art of =Making Vegetable Extracts for Medicinaland" other Purposes and that I have invented a new and useful machine for the application of such improvement.
The said improvement which I have discovered consists in the application of the liquid menstruum or solvent to the vegetable matter from which the extract is to be prepared, while such vegetable matter is in a vacuum and without the application of heat whereby the soluble principles of the vegetable matter are more readily extracted without sustaining any change or deterioration.
The said machine is described as follows reference being had to the drawings hereunto annexed and which are to be taken as part of this specification.
The drawing contains several views of the machine and its parts, and the lettering of the parts of the machine correspond in the several drawings.
(A) represents an air tight metal hollow cylinder with a cap at the top fitting'air tight and capable of being either removed or fastened by means of screws as represented in the drawings. The bottom of the cylinder is perforated with a hole which may be stopped with the screw represented in the drawing marked In the cylinder a movable piston head is to be fitted air tight which is represented in the drawing and marked (g, g). With the cylinder an air pump is connected marked (C) in the drawing, by means of the tube marked (k), which tube communicates with the cylinder by stop, cocks at (e) and (cl) of which (d) opens into the cylinder near the cap and (6) near the middle. A forcing pump of ordinary construction (marked (B) in the drawing) is also connected with the cylinder by means of the tube (g) which communicates with the cylinder by the stop cock (0) near the top of the cylinder. The tube (V) supplies either air or water to the force pump. The tube and the stop cock (Z1) communicate with the cylinder.. This tube is constructed at its junction with the stop cock in such manner that it may be reversed so as to bring the aperture of the tube into a vessel of liquid for the purposeafter mentioned. These are the materialjparts of machine which for-use in a large way should be conducted. upon the scale stated" in the drawing. V
jTo"work;this' machine thecap ofthe. cylinder should betake'noif and thepisto'n head (q, q) removed and the interior space of the cylinder filled with the vegetable matter from which the extract is to be made.
The piston head is then to be placed upon the top of the vegetable matter in the cylinder and the cap to be replacedand fastened tight by means of the screws. The screw (.9) at the bottom of the cylinder is also to be made fast, and the stop cocks at (Z2) and (a) and (0) are to be shut off. By.
these arrangements the cylinder is left, having no connection except with the air pump by means of the tube (71.) and the two stop cocks (e) and (d). The air in the cylinder both above the piston head and also below the same is then to be exhausted by the air pump as nearly as may be. This being done the stop cocks (e) and (d) are to be shut off, the tube (f) is to be inverted into a vessel containing the liquid solvent or menstruum, and the stop cocks (6) being. opened, the liquid will pass by force of the atmospheric pressure into the cylinder upon the vegetable matter and must be allowed to remain in contact with the vegetable matter for such time as is necessary to efiect a solution of the soluble principles of the, vegetable matter which must vary according to the substances from which the extract is to be prepared and the liquid solvent or menstruum used for making the extract and concerning which time no rule can be specified; However a much shorter time will suffice to effect the solution than would be requisite were the same not efi'ected after the exhaustion of the air. After the solution shall be thus eflected the stop cock (6) is to be closed, the screw (8) is to be loosened and taken out and the stop cock (0) opened and by applying pressure upon the piston head by means of the force pump which may be used either with air or water, the extract dissolved in the solvent or menstruum will be forced out in a pure condition, leaving the vegetable residuum deprived of all its solumanner.
.ble principles in the cylinder. The extract is then to be evaporated in the usual V The advantage of this improvedprocess consists in the very speedy solution of all liquid solvent or menstruum in, vacuum 5 Without heat, and also the mode of effecting the said operation by the apparatus hereinbefore described. 7 V
Of course I do not claim the air pump or force pump as my invention, but only-the combination of the cylinder air pump and 7 force pump for the purpose stated and in the manner stated. p r Dated and signed January 7, 184:3.
