Filtering Machine;—which filters per assensum.— | ||
![]() |
A. | Under Vessel |
B. | Upper vessel | |
C. | Netting or Hair-Cloth when Cyder is to be filtered.— | |
D. | Tube of Wood or metal leading from B to A.— | |
E. | False bottom full of holes | |
F. | Lower Cock, to be opened only to let out Water that has stood long or hot Water poured on the top after removing the Vessel B that all the impurities may be washed out.— | |
G. | Upper Cock to draw off fine Water. &c.— | |
H. | If the Water should require to be as cold as spring Water it may be let down this Tube into | |
I. | A Reservoir, in a Well of common Water, or in a deep dry well, covered over the Reservoir some feet with Earth, & the well tightly closed—It is obvious that as long as this is supplied with Water it will rise up the Tube | |
K. | which delivers it as pure as Spring Water by the Cock L.—This inverted Syphon may however be dispensed with:—but would be very convenient to cool rain Water in Wells of bad Water.— |
MS (DLC: TJ Papers, 203:36219); text and drawing entirely in Thornton’s hand; undated; on verso of last page of covering letter.
per assensum [ascensum]: “by means of ascent.”
