STRAINER.

Specification of Letters Patent.

Patented July 22, 1919.

I Application filed December 6, 1918. Serial No. 265,515.

To all whom it may concern:

Be it known that I, WALTER BRUCE WILLS, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Strainers, of which the following is a specification.

This invention relates to strainers for I domestic use which are supported when in use by a frame, and the invention relates more particularly to the means whereby the strainer body is attached to the frame, the object of the invention being to provide a simple and secure connection, and one which enables the strainer to be readily disconnected from the frame.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing forming a part of this specification.

In the draWing-.

Figure 1 is a side elevation of the device; Fig. 2 is a cross section thereof, and Fig. 3 is a plan view.

In the drawing, 5 denotes a strainer of.

conventional form having its top edge reinforced by a sheet metal band 6 as usual. This band has a rolled edge or bead 7 in which is embedded a stiffening wire 8, said wire being in two pieces as clearly shown in Fig. 3. At diametrically opposite points, the rolled over material forming the bead 7 is perforated,as shown at 9, and the ends of the wires are inserted through the perforations to extend from the bead outwardly. The projecting ends of the wires are fashioned into downwardly extending loops 10.

The strainer is supported by an extension frame composed of spaced sides 11 andends 12. This frame is made of wire and it consists of two members connected by eyes 13 forming guides through whichthe two mem- Gopies of this patent may be obtained for five cents each, by addressing the bers canslide upon each other. As this frame is of conventional form, a further description thereof is not necessary, and nothing is claimed for it.

The strainer is supported by the frame by placing it between the sides 11 of the latter, and engaging the loops 10 with said sides as shown in Fig. 2. Theloops are shaped to come beneath the frame sides, whereby the strainer is permanently secured on the frame. The loops do not rigidly fasten the strainer to the frame, leaving the former free to be adjusted alon the frame by sliding it toward one end or tIle other.

am aware that it is not new to support a strainer in a frame by means of side loops, but these hooks have been formed of a separate wire encircling the band 6, whereas in the present structure I utilize the reinforcing wire of the beaded edge of the band, with the result that the structure is simplified and cheapened, without weakening any of the parts.

I claim:

A strainer of semi-spherical form having a reinforcing band encircling its flat side and said band having a rolled edge forming a closed bead, a pair of stiflening Wires embedded in the bead each of a length less than half the circumference of the strainer and oppositely disposed with relation to the flat side thereof, whereby a space is left between the ends of said wires, the ends of the wires projecting from said bead and bent to form a pair of loops at opposite sides of the strainer, and a supporting frame adapted to slidingly engage said loops.

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

WALTER BRUCE WILLS.
