APPARATUS FOR STRAINING- LIQUIDS.

Specification-o1 Letters Patent. Pat nt d June 2'7, 1911.

Application filed October 23, 1909. Serial No. 524,136.

To all whom it may concern:

Be it known that we, FRANK BAILEY and "FISEDERICK HENRY JACKSON, subjects of the K n ,of Great Britain and Ireland, and

' cleanse the strainer, thereby rendering the apparatus self-cleansing.

In the specification of our United States Patent No. 943,908, dated December 21, 1909, is described a straining apparatus of the self-cleansing type, and our present invention consists in an improved construction of the straining medium or id.

Inthe accompanying rawings, Figure 1 is an enlarged fragmentary view of one con struction of grid; Fig. 2 is a similar view of another mode of construction. Fig. 3

illustrates a modification of the construction illustrated in Fig; 1. Fig. 4 is a still further modification, while Fig. 5 is a longitudinal section and Fig. 6 a plan of a portion ofthe intermediate plates shown in Fig. 4.

Referring to Fig. 1, the grid is formed of curved corrugated plates (1 arranged ridge to ridge and placed edgewise to the direction of the stream, so forming channels b'for the flow oithe liquid; the plates-being riveted or otherwise fastened together. Fig. 2 shows plates a having rectangular corrugations; the corrugations of each plate comciding with those of the contiguous plate and riveting being dispensed with.

According to the modified construction illustrated in Fig. 3, a plate 0 is interposed between the curved corrugated plates a, so forming a grid having a corrugated plate alternating with a flat plate. With such a construction of grid channels 6' areformed each having considerably less area than the channels I), thus affording a more erfect straining of the liquid. To still her strain the liquid, the lates a and 0 may be formed withV-shap'ed punched out of the plates so as to project from the opposite faces thereof and into the channels I), as shown in Figs. 3 to 6.

What we claim as our invention and desire to secure by Letters Patent is snags of, same being.

1. In a straining grid wherein, for the purpose of cleansin the straining surface, liquid is caused to ow in the reverse direction, a grid composed of corrugated plates to the direction of the stream.

' arranged ridge to ridge and placed edgewise 2. In a straining grid wherein, for the purpose of cleansin the straining surface, liquid is caused to ow in the reverse direction, a grid composed of corrugated plates alternatlng with flat plates; some of the plates being formed with laterally projecting snags.

3. In a straining grid wherein, for the purpose of cleansing the straining surface,

liquld is caused to flow in the reverse direction, the improved construction of grld composed of plates some of which are formed with snags which protrude into the passage or passages and present their points to the infiowing'liquid, substantially as set forth.

In testimony whereof we have signed our names to this specification in the pres'enceof two subscribing witnesses.
