GEORGE L. REYNOLDS, OF NEWARK, NEW JERSEY.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 428,413, dated May 20, 1890.

Application filed August 28, 1889 Serial No. 322,189. (No model.)

To all whom. it may concern.-

Be it known that I, GEORGE L. REvNoLDs, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in WVindow- Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and. to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to providea cheap and effective mosquito-screen frame capable of being quickly and readily adjusted to windows of varying widths, and free from certain objections inherent in frames of a similar character heretofore prodnced; and the invention consists in the improved frame and in the arrangements and combinations of the several parts thereof, as hereinafter set forth, and finally pointed out in the claim.

Referring to the accompanying drawings, Figure 1 represents a front elevation of a window and of my improved mosquito-screen frame adjusted therein. Fig. 2 represents an enlarged elevation of a detached portion of said frame, showing certain special features of construction. Fig. 3 is a similar view showing in section a modification of said features; and Figs. 4, 5, 6, 7, and 8 are detail views.

Similar letters of reference indicate like parts in each figure where they occur.

In carrying out my invention I construct the main body of the frame A B in the usual manner, except the stiles A A, which are provided with tongues 0, which enter and work in grooves 0 formed in supplementary stiles D, as will be understood upon reference more particularly to Figs. 2, 3, and 5. These stiles are arranged so as to be adjustable laterally to the extent of the depth of the said tongues and grooves, as the said figures will show, and to such extent the frames are capable of expansion and contraction, as will be obvious. Interposed between the edges of the tongues and the bottoms of the grooves are springs 6, Figs. 2, 3, and 5, the

normal tendency of which is to press the supplementary stiles outward against the window-casing and thus create sufficient friction to make the screen-frame cling to said casings and admit of being moved from bottom to top of the window onthe casing, and

vice versa, without the usual tongue and groove or other appliances attached to either the casings or to the screen-frame, as will be understood.

Two forms of springs are shown, one form in Fig. 2, which consist of two spring-wires 8, having one of their ends bent at a right angle, or nearly so, and driven into the stile proper of the frame, and their other ends projecting in opposite directions, forming halfelliptics, as shown, and another in Figs. 3 and 5. In the latter case ordinary helical springs are shown seated in sockets in the stiles proper, and guide-pins e are used in connection with the springs, as will be apparent upon reference to said Figs. 3 and 5. The guide-pins, however, may be dispensed with, if so desired.

WVhen the frames are not in use, the supplementary stiles are held in position by suitable hooks f, Figs. 1, 2, and 3, or other appropriate fastenings, as shown in Fig. 8. In this figure I have shown the hooks f secured firmly in the jamb and spring-plates f secured to the screen-frame. The normal tendency of the spring-plates is outward, so

that when the jamb and the frame are brought together the hook automatically engages an opening in the plate. WVhen it is desired to disengage the hook and the plate, it is necessary only to press upon the plate, as will be readily understood. At the top and bottom ends of the frameare arranged guide-plates g and h, the former, which is shown in Fig. 7, being secured to the main body of the frame, and the latter (shown in Fig. 6) to the supplementary stiles, as shown in Figs. '2 and 3.

It will be seen that the edges 1 andj of the sides and one end of the plate h are turned upward, forming a box, and that a section is removed from the center, as will be'understood upon reference to Fig. 6. The slot or groove formed by the removal of said central section fits around the tongue 0 and aids in holding the plate in position upon the stile,

as will be understood. The edges of the plates g are also turned to form lips or lugs k, which Work between the edges 2' and abut against the parts j and serve to limit the outward movement of the stile D, as will be understood upon reference to Figs. 3, 4, 6, and 7. The plates 9 also serve, as will be seen, to cover the open spaces 3, Fig. 5, and prevent the ingress of mosquitoes at those points.

It will be observed, Figs. 1, 2, and 3, that the Wire cloth or screen is let in flush with the outer surface of the frame, thereby preventing ingress of mosquitoes Without reference to the distance to which the sash may be raised, as will be understood. Provision is also made, by means of a spring-bolt 0 and a lever for operating the same secured to one of said supplemental stiles, (see Fig. 1,) for fastening the frame upon the inside, so that it cannot be raised from the outside.

Friction-blocks Z, Fig. 2, of rubber, glass, or other suitable material, may be inserted in the edges of the stiles, if desired.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

In a window-screen, the combination of the screen havingthe side pieces or stiles formed each with a tongue, the supplemental stiles provided with grooves to receive the tongues of the stiles, springs interposed between the stiles, plates secured to the screen at the upper and lower ends thereof, and provided at their outer ends with depending lips, plates secured to the supplemental stiles at their upper and lower ends, having slots to receive the tongues of the screen-stiles, and having their side edges turned up to form guides for the lips on the plates of the screen, and at their ends formed with lips to engage the lips of the plates of the screen for limiting the movement of the plates on the stiles.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of June, 1889.

GEO. L. REYNOLDS.
