IMPROVEMENT IN FILTERS,
The Schedule referred to in these Letters Patent and makingpart of the lama.
To all persons to whom these presents may come:
Be it known that we, GEORGE O PARKMN, of Linoolnville, and J oHN M. TRUssELL, of Belfast, in
-the county of' Waldo, and/State of' Maine, have invented a new and useful Filtering-Box or Apparatus; and We do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of Whieh-` x Figure 1v is a-perspeotive elevation of it, and
Figure 2, a longitudinal section of it.
In such drawings- A A A" are a series of' rectangular frames, made of wood or other proper material, and having along slot made vertically through each bar of each'fiame.
Below or within these trames are two parallel bottom boards, B C, each of which is to be foraminous, or provided with numerous holes.
rEhe frames are to be arranged, one directly over the other, and over the bottom boards, and with layers, a aa, or masses of sponge, or other proper fibrous filtering equivalent, arranged between such frames, and also between the bottom boards.
Clamp-bolts b b, provided with screws, go up through the bottom boards and the slots of the flames, and re" eeive nuts, c c, on their upper ends, such screws and nuts serving to confine the boards and frames together, and to the layers of sponge or filtering-material; also to compress the latter to such extent as may be necessary, from time to time, in -order to regulate its powers of iltration.
vThe slots of the bars of the frames, besides answering the purpose of receiving .the bolts, aid greatly in holding the sponge in place.
To use the lltering-appzuatus, water, or any liquid to be filtered, is to be suffered to run into it, from whence suoli liquid will ilow out of the bottom, sides, and ends of the apparatus, or through the sponge and orifices thereof', and will be filtered or separated from any impurities or foreign matters capable of being removed by the process of liltration.
We claim the arlangement and combination of perforated bottom boards B C, the series of frames A A A", vthe layers, a, of sponge, `and the clamp-screws and nuts, the whole beingsubstantially as and for the purpose hereinbefore specified.
GEORGE O. PARKMAN.
