Thepresentinvention constitutes an improvement on filters employing i3; casing and superposed cells confined ,wjthinthebalsing, as illustrated, for instance;, ;inim y application Serial No. 277,896, filed Septemberll, 1905;

and the gistof the invention lies in the employment of relatively swinging sections forming the casing, whereby easy access for the purpose of insertion and removal of cells 2 5 is provided.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents anelevational view of my improved filter, a portion being shown in section; Fig. 2, a horizontal sectional view taken as indicated at line 2 of Fig. 1, the casing-top being removed; Fig. 3, an enlarged broken vertical section taken as indicated at line 3 of Fig. 2, and Fig. 4 a perspective view 3 5 showing the relation of certain pivotal parts. In the construction shown A A represent standards carrying a cross-bar A with which is adjustably connected a casing-top A A A casing-sections supported on a base A". and connected with the standards, and B r'emovable cells located within the casing and confined between the top and base thereof.

The bar A is mounted toswing upon the standard A, one end of the barv being disenga eably connected with the standard A in a we l-known manner, the hook formation of the swinging end of the bar being indicated in section at a. The bar supports a top-actuating screw a which in turn is actuated by 5 a shaft a and hand-wheela in a well-known manner. i

The casing-section A is equipped with pivotal lugs a, and has hooks a engaging the standard 'A. 5 5 These members may be formed integrally,

with which the,lowersidepofrtliezadj alcentzlug;

The; .1arrangement; is; such-J that when-tthahandleg aiflis movedafromgthe; position of the full lines to the positionof thej dotted lines shown in Fig. 2 the up er casing- 7 5 I section will be lifted clear of the ower sec' 'tion, enabling the upper section to be swung upon its pivot.

Pressure is transmitted from cell to cell of the filter from top to bottom. The liquor enters at the base through an inlet 0 and passes into the annular chamber 0, between the casing and the peripheries of the cells, from whence it passes through the cells to the central conduit 0 andthence to the outlet 0 in the manner described in the above-designated application. Thus it will be underserves as a continuous casing, and the cel s are built up from bottom to top, the operation of the filter be- 90- mg the same as though the casing were of inte al formation.

en it is desired to remove the cells, the to is raised and swung to one side. The ce ls are then removed down to or below the 5 junction plane of the upper and lower casingsections, and the upper casing-section then 1s raised and swung in a direction to balance the top, enabling the lower cells to be readily reached; The reverse of these operations acroo complishes the assembling of the parts, the gasket a furnishing a liquid-tight joint between the casing-sections.

'I do notlimit myself todetails of construction.

What I regard asnew, and desire to secure by Letters Patent, is-

1. In a filter, the combination of a casing comprising relatively swin ing casing-sections having vertical pivota connection, and 1 to oted on the other of said standards,

filter-cells contained in the casing-sections, V

for the purpose set forth.

2. In a filter, the combination of superposed relatively swinging casing-sections, a swinging casing-top, and superposed cells located within the casing-sectlons and confined between the top and bottom of the casing, for the pur ose set forth.

3. In a lter, the combination of a stationary lower casing-section, a superposed oasing-section, a gasket confined between said casing-sections, a vertical pivot for the upper section, means for raising the upper section to permit it to be swung on its pivot, a casingtop, and a vertical pivot for the-casing-top, for the purpose set forth.

4. In a filter, the combination of a lower casing section, opposite standards rising above the same at the sides thereof, a swinging upper casing-section pivoted on one of said standards, and a swinging casing-top pivfor the purpose set forth.

5. In a filter, the combination of two superposed casing-sections, pivotal connection between said sections at one side, and a cam located at the pivotal connection and serving to elevate the upper casing-section, for the purpose set fort 6. In a filter, the combination of a lower casing-section, standards arising from opposite sides of the same, an upper casin -sectlon having a pivotal lug connected with one of said standards, a cam-ring supported beneath said pivotal lug and equipped with an actuating-handle, and a caslng-top adjustably connected with said standards.

7. In a filter, the combination of a lower casing-section, standards arising at opposite sides thereof, a stationary cam on one of said standards, a coacting cam-ring supported thereon, a casing-section having at one side a pivotal lug supported on the cam-ring and at the other side a hook engaging the opposite standard, a vertically-adjustable casing-top having a supporting-bar pivoted on the lastnamed standard and provided with a hook engaging the other standard, and nuts serving to secure the bar to the tops of said standards, for the purpose set forth.

8. In a filter, the combination of a base, a series of filter elements, surrounded partly by a stationary drum and partly by a movable drum swinging around a vertical axis.
