s'mamnn' Specification of Letters Patent.

Application filed June 18, 1914. Serial No. 845,864.

To all whom it may concern:

Be it known that I, IRVIN citizen ofthe United States, and a resident of Fargo, in the county of Cass and State of North Dakota, have invented certain new .and useful Improvements in Strainers, of

which the following is a specification.

This invention relates to improvements in a milk-strainer that comprises primarily a funnel-shaped receptacle provided with means for securing a filtering medium over its outlet.

The object of the present invention is to provide means for securing over the outlet of the receptacle a comparatively thick mat of fibrous material, such'as, absorbent cotton in its ordinary commercial form.v I

The invention consists in the novel construction, combination and arrangement of parts hereinafter described, polnted out 1n the appended claims, and illustrated by the accompanying drawings- In the drawings, in which similar reference characters designate corresponding parts, Figure l is a vertical sectional view of a strainer embodying the invention. Fig. 2 is a detail perspective view-of a mat of .fibrous material. forming the filtering medium. Fig. 3 is a detail perspective view of in an open position. Fig. 4 is a plan the reticulated clamp for holding the filtering medium in place, the clamp being shown new of the clamp, showing it closed.

Referring to the drawings, the body 1 of the receptacle is of the usual funnel-shaped formation. Secured to its lower or outlet end is the reticulated cylindrical extension 2,

' opening at the top into the receptacle and in its ordinarycommercial form and has pose.

been found to be well adapted to the purthickness and its lower edge is packed into the annular groove formed by the fianges4,

5, to prevent the liquid from escaping from the extension between the bottom 3 and the lower edge of the mat. The upper edge ef L. JAMES, a.

the mat extends above the loweredge of the receptacle to prevent the liquid from escapingPa-t that place.

he mat 6 is held in place upon the reticulated extension by, the foraminous clamp 7. The latter is formed of two members hinged together, as at 8, and when closed it has a cylindrical shape to fit tightly over the mat around the cylindrical extension 2. The clamp, when in place, projects above the lower edge of the receptacle to hold the'mat firmly in place against such edge to prevent leakage. The two members are held closed by the locking arm 9 on the edge of one member engaging the bail 10 on the edge of the other member. In closin the clamp the arm 9 is passed through the all 10 and the arm is turned back against,the clamp as shown in Fig. 4. As the arm has considerable length it acts as a lever and the two members of the. clamp can be forced together with considerable pressure around the mat on the reticulated extension. In this way the mat is firmly held in place and leakage of the fluid past its edge is prevented. With the mat ,in place, the liquid poured into the upper end of the receptacle in escaping from the outlet at the lower end must pass the reticulated cylindrical wall of the extension 2, the mat 6, and the foraminous clamp 7 While the reticulated wall of the extension and the foraminous clamp firmly hold the filtering mat in place, yet they other no obstruction to the free flow of the liquid through the met. In passing through the mat the deleterious matter is filtered from the liquid. It is to be observed that the mat prcsents'a comparatively large filtering area to the li uid, which permits a ready flow of the liquid through the receptacle. By manipulating the foraminous clamp a new mat can be readily put in place.

Having thus described my invention,'what I claim and desire to secure by Letters Patent is:

1. In a strainer, a receptacle provided with an' outlet, a cylindrical extension extending over'the outlet ofthe receptacle, said extension having an imperforate bottom and itscylindrical wall reticulated, a foraminous clamp comprising hin ed members shaped to fit'over the cylindrical extension of the receptacle, and means for fastening the hinged members together when closed over the cylindrical extension.

2. In a strainer, a receptacle provided with an outlet, a reticulated cylindrical extension extending over the,outlet of the receptacle, an imperforate bottom on said cylindrical extension, flanges on saidbottom forming an annular groove outside of the extension, and a foraminous clamp to fit over the cylindrical extension above said annular groove.

3. In a strainer, a receptacle provided with an outlet, a reticulated extension extending over the outlet of the receptacle, a foraininous clamp comprising hinged members shaped to lit over the reticulated extension, and means for fastening the hinged members together when closed over the reticulated extension.

4. In a strainer, a receptacle provided with an outlet, a cylindrical extension extending over the outlet of the receptacle, said extension having an imperforate bottom and its cylindrical wall reticulated, a filtering mat to lit over the cylindrical wall of the extension, a foraminous clamp comprising hinged members shaped to fit over I means for fastening the hinged members together when closed.

5. In a strainer, a receptacle provided with an outlet, a'reticulated cylindrical extension extending over the outlet of the receptacle, an imperforate bottom onsaid cylindrical extension, flanges on said" bottom forming an annular groove outside of the cylindrlcal wall 01' the extension, a filtering mat placed over the reticulated cylindrical extension with its lower edge inserted in said groove, and a foraminous clamp f0 holding the mat upon the extension.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
