TO ALL WHOM IT MAY CONCERN:

Be it known that we, ROBERT M. HOLLAND and ANDREW J. HInBS, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Elastic Stretching and Supporting Frame for Mosquito-Bar Netting in windows, doors, &c., of dwellings; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing, making a part of this specification, and to the letters of reference marked thereon.

The object of our invention is to aiford a more simple, inexpensive, and easily applied stretching and supporting frame for mosquito-bar netting when applied to the openings of doors or windows of dwellings, &c;, for preventing the entrance of mosquitoes and other insects; and our invention consists, substantially as hereinafter described and shown, of two light or delicate metallic pieces pivoted together at their mid lengths so as to allow of their being vibratedon each other easily, and having each of their ends made hollow to the depth of an inch, more or less, for receiving, respectively, four spiral or other springs, about half an inch long, and the one end of four straight wooden stems, so that the said stems will be supported by the sockets and upon the springs therein, respectively, and also extend radially therefrom to a sufiicient length to reach the corners of the open window-frame, the outer ends of the said stems being connected by means of listing or other flexible and slightly elastic fabric, so that the latter will be kept moderately stretched-when applied properly in the :open window-frame, and thus support a mosquito-bar netting sewed to the listing in such a stretched and close manner over the opening as will effectually preclude insects.

Referring to the drawing, which is an elevation of the whole device in a window-frame, and showing one of the sockets and its spring in longitudinal section, A A being the two light metallic socket-pieces, pivoted together at a; B, one of the four springs in its socket; C C G, the four wooden steins;.'D D D D, the listing con. necting the stems together at their outer ends; E, the mosquito-bar netting as sewed fast to the listing D, and Fthe open window-frame in which the invention fits. The socket-pieces A.A are made as light and delicate as a proper degree of strength may requirein them to support the stems C so that they will bear elastically upon the springs B in the sockets when the outer ends of the said stems C are secured together by the attachment ofthe listing D, so as to cause the latter to slightly compress the springs B by pressing on the stems C, the lengths of the stems C being adapted to the size of the open frame F in which the screen is to be applied, substantially as sho n in the drawing. The mosquito-bar fabric E is laid flat and sewed fast upon the listing D, as shown. It will therefore be seen that the four corners of the device ,can be easily forced inward in the direction of the sockets of the stems, and that, when released from the hand, they will spring out so as to tighten or straighten the listing D. The whole frame of the device is therefore made to fit in the run" of a sash or door-frame, and is applied therein by compressing its corners so that it will pass into the runs or rebates of the window or door-frame, and lie closely against the sides of the same, as shown in the drawing. This is a very simply and 'inekpensively-cnnstructed device for the purpose, and it can be readily cut and fitted to any door or windowframe; and by withdrawing the stems C from their sockets the whole can be folded into avery small package for transportation or packing away in the winter.

- What we claim as our invention, and desire to secure by Letters Patent, is-- The sockct-pieces A A, with their enclosed springs B, together supporting the stems C C C C elastically, in combination with the listing D, or its equivalent, for holding the mosquito-netting E, the said parts being constructed and arranged to operate together substantially as and for the purpose described.
