SCREEN-DOOR.

SPECIFICATION forming part of Letters Patent No. 477,562, dated June 21, 1892.

Application filed March 5,1892.

T0 at whom it may concern;

Be it kno'ivn that \ve,\V1LLIAM F. LIPP, residing at Dayton, in the county of Montgomery and State of Ohio, and ELIJAH J. PRESTON, re siding at Alexandria, in the county of Campbell and State of lientucky, citizens of the United States, have invented certain new and useful Improvements in Screen-Doors, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a front view of our improved door; Fig. 2, a vertical sectional view thereof on the line 2 2; Fig. 3, a horizontal section on the line 3 3 of Fig. 1, and Fig.4 a detail view of the adjustable end rail.

This invention relates to certain improvements in adjustable screen-doors; and it consists of certain novel features of construction and combination of parts that will fully hereinafter appear, and be particularly pointed out in the claims appended.

In the drawings, a a designate the stiles or side bars of the door-frame, and b b b the three cross-bars connecting the side bars at their ends and at a su table point between their ends. The lower and intermediate bars or rails are permanently secured to the side bars by mortising and tenoning or otherwise. The wire-netting is secured on the face of the frame by means of the clamping-strips c, suitably fastened to the same, these strips extending along near the inner edges of the side bars and end rails, the upper strip not being secured to the upper rail, but extending across in front of it, so as to obscure and protect the upper edge of the netting. The upper crossrail 5 is vertically adjustably secured behind the upper edge of the screen between the upper ends of the side rails by means of tenons b, projecting from its ends and fitting and sliding in vertical grooves formed in the ad jaccnt edges of the side rails, the grooves extending down a suitable distance to accommodate doors of various heights. The grooves are closed that is, they do not extend entirely through the side rails-s0 that they do not unduly weaken the rails, but leave them solid and unmutilated on their outer surfaces. The tenons have frictional adj ustment in the grooves, so that the bar may be Serial No. 423,848- (No model.)

readily adjusted up or down behind the upper edge of the screen under a suitable pressure, and to prevent the side rails spreading the tenons are enlarged or dovetailed at or near their ends, and the grooves in the side rails are similarly enlarged for their reception, as shown. The tenons may be formed on the ends of the bar or they may be of metal and secured in the ends, as shown, the latter being preferred, as it enables the. tenons and grooves to be made narrower.

This improved adjustable door is manufactured and sold in the condition above described--that is, it is put on the market ready made, the lower and intermediate rails being rigidly secured to the side rails and the upper rail frictionally held in the grooves behind the upper screen-securing strip, the screen being also permanently secured to the rails. To tit and hang the door, the purchaser simply adjusts the upper rail along in the grooves to the proper height and then saws olt the projecting ends of the side rails flush with the upper edge of the cross-rail. If nec essary, the edges of r the side rails may be sawed or dressed off, these rails being made of a sufficient width for this purpose. When the upper rail is properly adjusted, it may he seemed in place orprevented from dropping, it necessary, by small nails or other means, and the upper edge of the screen may be clamped by securing the upper clampingstrip to it.

Instead of making the upper rail adjustable, as shown, the lower one may be made adjustable and the upper one secured rigidly, the same purpose being accomplished in either case, It will be observed that by thus com pletely constructing the door before putting it upon the market purchasersare not required, as in that class of doors known as knockdown doors, to assemble and adjust and secure the parts of the frame together and then fit and secure the screen to the frame, this being all done by the manufacturer.

Having thus fully describedour invention,

what we claim, and desire to secure by Letters Patent, is-

1. An adjustable screen'door consisting of the vertical side rails a a and the cross-rails Z) Z) I), one of the end cross-rails being pro Vided with oppositely-projecting enlarged tenons 12, working in closed vertical grooves formed in the inner edges of said side rails, said tenons having frictional adjustment therein, and the other cross-rails being permanentiy secured to the side rails, a wire-netting secured to the inner edges of frame-bar by strips 0, one of these strips extending across in front of the adjustable erossrail, so as to protect the unsecured edge of the netting, substantially as described.

2. A ready-made adjustable screen-door consisting of the side bars a a and the crossrails permanently connecting the said side bars, one of the end cross-rails being adjustably secured between the side rails by means of tenons working in grooves in the inner edges of the same, a wire-netting permanently secured to the door-frame by vertical and transverse strips 0, one of these strips extending across in front of the adjustable cross-rail and unsecured edge of the wire-ne tting, but unconnected with the cross-rail, whereby the adjustable rail is free to be adjusted up and down without disturbing the netting and the rail may be secured after adjustment to the screen-strip in front of it, substantially as described.

In testimony whereof we affix oursignatures in presence of two witnesses.
