TO ALL WHOM IT MAY CONCERN:

"Be it known that I,'V..BAnKnr., of Otisfield, in the county of Cumberland, and State ofM-aine, have invented a new and improved Mosquito Bar and I do hereby declare that the following isa full, clear, and exact description thereof, reference being bad to the accompanying drawings, forming part of this specification.

The nature of my invention consists in constructing, in a peculiar and novel manner, the corners of frames for screens to windows, to prevent mosquitoes, flies, and other insects, from entering the house, and for mosquite bars over beds and other places Where it is desired to prevent fliesand mosquitoes from entering.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction.

Figure 1 is a top plan view of my improved frame.

Figure 2 is a plan or pattern by which I cut the sheet metal for the corners of the frame.

Figure 3 is a corner with a section of wooden bars inserted.

Figure 4 is a section of one of the bars, showing the groove in which the netting is inserted, and the tongue or bar that fits the groove and holds the netting in its place. v

Figure 5 is a transverse or cross-section of one of the bars, taken from the line m.

Letters of like name and kind refer to like parts. in each of the figures. V

A represents a piece of sheet metal, cut in the proper form, ready to be bent to make one of the corners of my improved frame. This sheet of metal is bent longitudinally in line with the dotted lines a a a a. After being thus bent a sort of square tube is formed, with the exception that one side is left partially open, as the edges do not meet. After the sheet has been bent as above described, it is then bent or turned at right angles at the line 0, which brings the bevelled portions of the plate to meet and form a mitre-joint, as shown at 2' i. It also brings the tongue (2 in such a position as to pass through the slot or mortise n, the endof the said tongue being turned or clinched down at the line I, which makes a strong and durable corner in which bars may be inserted into the socket thus formed to make a frame for the purpose above mentioned. B represents a screen made after my improved plan; D may represent the four corners pr sockets of my improved frame, the said corners being made as before described. C represents four bars, made of wood, with the ends mitred so as to meet and fill the corners of the sheet metal or sockets. In the said bars 0 are grooves E, cut in a longitudinal direction with the bar, in which is fitted a tongueor bar, to, for the purpose of holding the netting or fabric.

When the frame is made to any'desired size the fabric or netting is laid up on the frame, when the tongue is pressed down forcing the edge of the netting into the bottom of the groove and holding it in place. This frame is strong, simple, and cheap in its construction, and light, requiring but a small amount of material, the model representing full-size material of which the frame is designed to be made. It will be understood that the sockets D may be perforated, so that nails may be driven toihold the sockets to the wood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. The corners of a frame made from sheet metal, as herein shown and described, and for the purposes set forth.

2 1 also claim the bars C, provided with grooves, in which is fitted a tongue, in combination with the socket corners, substantially and for the purposes-herein shown and described.
