-ADJUSTABLE SCREEN-DOOR.

SPECIFICATION forming part of Letters Patent No. 374,187, dated December 6, 1887.

Application tiled September 9, i887. Serial No. 249,234. (No model.)

To aZZ whom, it may concern:

Be itknown that I, WILLIAM HUGHES, a citizen of the United States or" America, residing at Minerva, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Adjustable Screen-Doors, of which the following is aspecication, reference being had therein to the accompanying drawings.

My invent-ion relates to screen-doors; and it has for its object to produce doors of this class which will be capable of adj ustrnentto tit openings of various sizes.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claims.

Figure 1 of the drawings is afi-ont elevation, partly in section, of a door provided with the auxiliary screen and expanded to full width. Fig. 2 is a front elevation of a door without the auxiliary screen and adjusted to its narrowest limit. Fig. 3 is a vertical section of the door taken on the line a." fr, Fig. 1. Fig. 4 is a plan View oftheanxiliary screen.

Referring to the drawings, A A are the side rails of the door,which are made the length of doors of the largest size common in dwellings. These rails are about four and one-half inches in width and are grooved on their inner edges, as at a, to the depth of about three and one-half inches, and in these grooves are placed springs B, which press against the screen-frame, hereinafter described, and adjust it in accordance with the width of the door.

O C represent the cross-rails'of the door, each of which :is constructed in two pieces, c c,one of said pieces, c', being tongued on its inner side, as at 1, and the other, c, correspondingly grooved, as-at 2. Both pieces are reduced in -thickness for the greater portion oftheir length, leaving a shoulder, 3, (seen in full and dotted lines,) where the reduction commences, so that when they are put together the cross-rail will be of one thickness throughoutits length. VBoth pieces are also rabbeted, as at 4, so that when they are together these rabbets will form a groove for the reception of the screenname, as clearly shown in Fig. 3. One end of each piece c and c is tenoned to fit in groove a in side rails, A, as seen in dotted lines, and is rigidly secured therein by screws, glue, or other suitable means. The pieces are held together adjustably by headed bolts 5 and screwthreaded nuts 6, the said bolts passing through a hole, 7, and a slot, 8, in each piece, the hole in one piece registering with the slot in the other piece, as seen in full and dotted lines.

D represents the screen-frame, and E the wire-cloth screen. This frame is of just suiicient thickness to work freely in the grooves a and 4 in the side rails and crossuails, respectively, and it is of a width and length suitable for the smallestsize door in common` use, as seen in Fig. 2, wherein the door is illustrated as adjusted to its narrowest limit and the side rails cut off on a line with the top ofthe upper cross-rail.

As before stated, in the manufacture of these screen-doors I make the side rails of a length suitable for the largest doors in common use. Now, when a doorlarger than the smallest size is required, I provide an auxiliary crossrail, F, constructed precisely like the rails C, to each piece of which I attach a strip of wirecloth, f, long enough to extend slightly beyond the middle of said piece, so that when rail F is extended to its full width the meeting ends of these strips will slightly overlap, as seen in Fig. 1, and thus freely slide oneupon the other while the rail is being adjusted to a less width, as seenin Fig. 4. I secure this auxiliary rail in the grooves of the side rails at the proper height for a door of the desired length, trim oi" the wire-cloth at the bottom, so that its lower edge will just rest on top of the upper cross rail O, and then, if the door is not to' be of the full lheight of the side rails, cut the latter off on aline with the top of the auxiliary rail. The door can then be adjusted as to width in an obvious manner.

Having thus described my invention,what I claim, and desire to secure by Letters Patent,

1. The combination, with the side rails grooved on their inner edges, springs located in said grooves, the twopart adjustable crossrails rabbeted to form grooves, as specified, and bolts and nuts for adjustably securing the parts of the cross-rails together, of the screenframe and screen, the former adapted to t inthe grooves in the side rails and cross-rails and l the meeting` ends of which overlap each other, bear against the springs in the side rails, for the whole constructed, arranged, and operatthe purpose set forth. ing in the manner above set forth.

2. The combination, with the grooved side In testimony whereof I affix my signature in 5 rails, the springs therein, the two-part adj ustapresence of two Witnesses.
