STRAlNER.

SPECIFICATION fog part of Letters Patent No. 688,397, dated December 1 0 Application filed February 18, 1901. Serial No. 47,745. (No model.)

Toall whmn it may concern; 7

Be it known that I, LEONARD H; DEs IsLEs,

a citizen of the United States,residing at Cam which the following is a specification.

My invention is intended to provide a simple and practical strainer which may be readily attached to and detached from a kettle, stew-pan, orsimilar devicewhen desired.

A strainer made in accordance with my invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of the strainer secured to the top ofv a stew-pan. Fig. 2 is a section on the line 00 w in Fig. 1. Fig. 3 is a plan view of a slightly modified form of strainer. Fig. 4 is a plan view showing another modification, and Fig. 5 is a section on the line 1 'y in Fig. 4.

My strainer comprises, generally speaking, a perforated body portion or strainer proper, in combination with novel means for clamping said body portion to the top of the vessel with which it is to be used.

The perforated body portion 2 of the strainer may beof any desired construction; but it preferably consists of a frame 3, covered with Wire-netting 4, the edge of which is wrapped around said frame or is otherwise secured thereto. In the form of strainer shown in the drawings one side of the frame 3 is curved to conform substantially to the outline of a portion of the top of a stew-pan or similar vessel 5, being provided with a projecting portion 6 to cover the nose of said vessel, while the inner side of said frame 3 is straight but the particular form of the body portion 2 is not material so far as my invention is concerned.

My improved clamping device for securing the body portion 2 to the vessel 5 comprises two downwardly-projecting hooks or fingers 7, soldered or otherwise rigidly secured to the curved edge of the body portion 2, and thus forming practically a part thereof,and an arm 8, pivotally connected with said body portion at a point near enough to the hooks 7 so that it will always lie between the same and the center of any vessel to which the strainer is adapted to be applied, said arm 8 being proing projections or fingers 9, adapted to engage the edge of the vessel 5 at a pointsubstantiall y opposite to the hooks 7. The hooks 7 may conveniently be formed from the ends of a stiff piece of wire, the central portion 10 of the latter being bent tolie close to the top of the body portion 2 and provided with the pivot 11, on which the arm 8 turns. It is desirable, although not essential, to provide a considerable degree of flexibility and elasticity at some point between the hooks 7 and the arm 8, for areason hereinafter described, and I have shown in the drawings several arrangements for accomplishing this result. Thus in Figs. 1 and 2 said central portion 10 is formed like a double 8, as shown at 12, while in Fig. 3 the central portion 10 is straight, and the desired flexibility is ob tained by inserting a bow-spring 13 between the arm 8 and the pivot 11, said bow spring being rigidly secured to said arm 8 and journaled on said pivot 11, as shown. In Fig. 4 said central portion is corrugated, as shown at 10 The hooks 7 are sufficiently near each other to insure their engagement with one side of the vessel 5 regardless of its size, and in order to adapt my strainer to be used with vessels of difierent sizes I have shown in Figs. 1, 2, and 3 a number of projections 9, formed vided with one or more downwardly-extendon the arm 8, preferably by stamping them from its substance and bending them downward, as shown. In place of having a number of such projections the arm 8 may be provided with a slotted clip 14, arranged to slide on said arm and having a downwardly-pro j ecting end 15, which forms an adjustable finger adapted to engage the edge of the vessel, as shown in Figs. 4 and 5. In this form of the device the clip 14 is retained in any desired position on the arm 8 by the binding of the edges of the slot 16 on saidarm in a wellknown manner and is released by pressing down the thumb-piece 17, said slot being sufficiently large to permit the clip 14 to tilt the proper amount to accomplish these results.

To attach the strainer shown in Figs. 1, 2, and 3 to a vessel, the body portion 2 is laid over one edge thereof, with the hooks 7 projecting downward and engaging the side of said vessel. The arm 8, which has previously been moved a little to one side of its central position, is then placed against the top of the opposite edge of the vessel, thus bringing said edge in front of one of the projections 9, and is moved toward the position shown in Fig. 1, whereupon, since the point at which the arm 8 is pivoted to the body portion 2 is located between the hooks 7 and the center of the vessel, said movement of the arm 8 will cause that projection 9 which lies next outside of the edge of the vessel to bind against the same, thereby clamping the vessel between said projection and the hooks 7 and securing the strainer firmly in place.

Byproviding a suflicient number of projcctions 9 my strainer may be adapted to be attached to vessels of any desired size, the f unction of the spring connection between the arm 8 and the body portion 2 being to provide forthe movement of said arm into its central position even though the edge of the vessel be engaged by a projection 9 at some distance from said position. The force of the clamping action is thus measured by the tension of said spring connection when employed.

To apply to a vessel that form of my device which is shown in Figs. 4 and 5, after the arm 8 has been swung a little to one side and the body portion 2 has been applied to the vessel the clip 14 is slid against the opposite edge of the vessel and the arm 8 is moved toward the position shown in Fig. 4, whereupon said clip let is caused by the engagement of its end 15 with the side of the vessel to bind against the arm 8, as above explained, and said end 15 thereupon clamps the vessel between itself and thehooks 7 in the manner above set forth.

I do not consider my invention to be limited to any particular form of body portion nor to any particular arrangement for pivotally connecting the arm 8 thereto, since these details may be varied at will, nor is my invention limited to the provision of a flexible connection between the arm 8 and the body portion 2, since such connection may be omitted, if desired, without materially affecting the efiiciency of the device, particularly when the adjustable clip shown in Figs. 4 and 5 is employed.

I claim as my invention 1. A strainer comprising a perforated body portion provided with two downwardly-projecting hooks adapted to engage one side of a vessel, in combination with an arm pivotally connected with said body portion and provided with a downwardly-extending finger adapted to engage the opposite side of said vessel, substantially as described.

2. A strainer comprising, in combination, a perforated body portion having two downwardly projecting hooks rigidly secured thereto and adapted to engage one side of a vessel, an arm provided with a downwardly.-.

extending finger adapted to engage the opposite side of the vessel, and a flexible connection between said arm and body portion, said arm being pivotally attached to said connection.

3. A strainer comprising a perforated body portion, a wire secured thereto and having its ends formed into downwardly-projecting hooks, and an arm pivoted to said wire and provided with one or more downwardly-extending fingers, for the purpose set forth.

4. A strainer comprising a perforated body portion, a wire rigidly secured thereto and having its ends formed into downwardly-projecting hooks, the central portion of said wire being bent to form a spring and provided with a pivot, and an arm journaled at one end on said pivot and provided with a number of downwardlyextending projections, substantially as described.

In testimony whereof I have hereunto subscribed my name this 11th day of February, 1901.
