IMPROVEMENT IN CLAMPS FOR MOSQUITNET FRAMES.

Specification forming part of Letters Patent No. P12295, dated February 10,1874; application filed January 12, 1874.

To all whom it may concern: p

Beit known that LWILLARD M. WHITE, of Canton, Hartford county, Connecticut, have invented an Improved Clamp, of which the following is a specification, reference being had W taching the extension-rod, which supports the spreader, to the head or foot board ot' the bed, or the like. It obviously may have other uses.

The invention consists in the combinations of parts set out in the claims at the end of this specication, and what is not therein claimed is supposed, so far as this present invention is concerned, to be old.

The letter a indicates one leg of the clamp, and `b the other. From the former project the mortised lugs al a2, designed to hold the lower joint of the extension-rod. The letter i indicates a thumb-screw, bearing against the extension-rod c. From the inner side of the leg aproject two spurs or teats, f f1, connected by the cross-pin f2. (Shown in dotted lines.) The leg b has a hook, b2, taking hold of the crossbarfz, thereby pivoting the two legs together. In the top of the leg b there is pivoted the swivel g, through which runs the thumb-screw h., its inner end bearing against the upper end of the leg a, whereby the feet ou the lower ends ofthe two legs can be pressed together as hard as desired, so as to grasp the head or foot 'board c. On the lower end of the leg a is a broad foot, s. On the lower end of the leg b is a similar foot, o. One or both these feet are hinged or pivoted to their respective legs. I have shown the foot o thus pivoted. The purpose of this is to make both the feet atly embrace the two sides of the board c, whatever, within obvious limits, be its `thickness, which would not be the case if beth the feet were rigidlyattached to their respective legs. On the lower end of the-leg b are cast two trunnions, t t. The foot 0 has bear= ings for these two trunnions, and, being of some malleable metal, as malleable cast-iron, it has four projections, m m .fr x, cast upon it, which are afterward turned down upon the two trunnions, so as to secure the foot to the leg, and yet leave a joint.

Of course, any common method of hinging the leg to the foot would answer the purpose, but this' particular manner enables me to cheapen the manufacture of the article. The joint which connects the two legs is also peculiar, and has its advantages. It is obvious that a common joint or pivot would answer the purpose, but the methodiI describe has two advantages: It enables me to cheapen the manufacture. of the article, and it enables me to take the two legs apart without trouble, so that they can be then packed in a smaller space, which is an important matter, as I de sign the whole mosquito-frame to be very portable, so that it can be packed in the valises and bags of travelers.

I claim as my inventionl. The combination of the two clamp-legs a and b by means of the projections f f1, cross-bar f2, and the hook b2, whereby the two legs are jointed, and yet readily separable, all substantially as shown and described, and for the purposes set forth.

2. The combination of the two clamp-legs a b, jointed together, and provided with feet o s, one or both ot which are pivoted and adjustable, substantially as shown and described.

3. `The leg b and foot 0,' provided with a joint consisting of the trunnions t t, bearings for I/Vitnesses z WM. EDGAR SIMoNDs, S. J. SmoNDs.
