    Waites Improvements in the Preparation of Infusions, cfc. sizes, but all fitting the one pump separately, so that a longer or shorter chamber may be used according to the quantity of ingredients to be operated upon. I may here observe that I am aware that infusions or extracts have been proposed to be made by forcing liquid upwards through the ingredients by 5 means of the pressure due to the weight of a column of the liquid employed, and therefore I lay no claim to the absolute use of hydrostatic pressure in making infusions; but what I do claim as novel and original, and as the Invention secured to me by the herein-before in part recited Letters Patent, is,— 20 First, the system or mode of making infusions, tinctures, extracts, and essences, wherein the liquid employed is forced, by the aid of a force pump or mechanical pressure, through the ingredients, as herein-before described. Second, the peculiar construction and arrangement of apparatus for making infusions, tinctures, extracts, or essences as herein-before described and illus- 15 trated by my Drawing. In witness whereof, I, the said Joseph W^aite, have hereunto set my hand and seal, this 27th day of January, One thousand eight hun¬ dred and sixty. JOSEPH WAITE, (l.s.) 20 LONDON: Printed by George Edward Eyre and William Spottiswoode, Printers to the Queen’s most Excellent Majesty. 1860.
