UNITED STATES PATENT QEEICE.

IMPROVEMENT IN FILTERS.
Specification forming part of Letters Patent No. 140,907, dated July 15, 1873 application filed April i6, 1873.
To all whomv t may concern.-
Beit known that I, JAMES M. EVARTs, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in the Construction of Filters; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon making a part of this speciication.
The nature of this invention is an improvement in the construction of filters; and the invention consists of a ring for receiving the filtering substance and retaining it in position, on which au angular rib is formed to receive an elastic packing, by means of which the ring is tted in arecess in the filter-shell in such manner as to form a perfectly water tight joint.
ln the accompanying drawings, Figure 1 represents a transverse section of my filter, showing the packing of the diaphragm and the construction of the shell before the halves are secured together; and Fig. 2 is a side elevation of my filter with the halves joined.
Similar letters of reference indicate like parts in the several figures A represents the upper half of a filter-shell and B the lower half of the same. These it is designed to form by spinning thin metal into the required shape. Near the upper and lower edges 0f said halves are formed annular recesses a b, and the lower edge of the upper half A of said shellr is formed with a projecting lip, c, within which is received the edge of the lower half B of said shell, as shown in Fig. l. The porous or ltering substance is surrounded by a ring, C, of thin metal having an angular rib, D,.formed thereon. Around the rib D is stretched a ring of India rubber, e, in such manner as to cover said rib, as shown in Fig. 1. The diaphragm thus provided with a packing is placed into the recess b of the lower half B of the shell, the rubber packing resting snugly within said recess, and the upper half A of said shell is then placed on said lower half, the edge of said lower halt' being received within the lip c of the upper half A, as before described. The two halves of the shell being in this position, with the diaphragm between them, the rubber packing e tightly lling the recesses a and b in each shell, the lip c is then turned slightly down upon the lower half B of the shell, lirmly holding the two halves of said shell tightly together, so that no solder or cement may be used.
From the foregoing description it will be seen that a filter constructed as hereinbefore described is not only very cheaply construct stance, constructed with an angular rib, in
combination with an elastic packing, so that said ring may be fitted in the recessed shell, as described.
