COMBINED SCREEN AND STORM DOOR..

D'PECIEICATIQN 'forming pari; of Letters Patent No. 321,936, dated July 14, 1885.

j Application filed May 16, 1885. (No model.) y.

To all whom t may concern.-

Be it known that I, CHARLEs ANDERsoN, a citizen of the United States, residing in Downers Grove, in the county of Du Page and State of Illinois, have invented anew and useful Improvement in Combined Screen and Storm Doors, of which thefollowing' is a specication.

My'invention relates to combined screen and storm doors, and more particularly to certain improvements upon the screen and storm door for which Letters Patent No.313,844 were granted to me under date of March 17, 1885.

In my present improvement the clamps which vsecure the removable panels to the frame of the door consist of bars or iron strips extending entirely across the paneland projecting sufciently beyond the inside shoulders of the panel to engage the mortises or recesses in the frame. The clamps are also secured to the panel immovably and slide therewith instead of thereon, as in my former patent. To permit this side movement of the panel for the purpose of removing and applying the same, I make the shoulders or the portion ofthe panel which fits in the opening in the frame somewhat narrower than said opening.

In the accompanying drawings, which form a part of this specification, and in which similar letters -of reference indicate like parts, Figure l is a side elevation of a door embodying my invention, showing thesame with two of the removable panels applied and two removed. Fig. 2 is a back view of the removable panels, one of the clamp strips or bars being omitted. Fig. 3 is a cross-section showving the manner in which the removable panels are applied; and Fig. 4 is a similar view, showing the panels in place and in readiness for tightening the clamp-screws.

In said drawings, A represents a door-frame;

B, screens. secured in the panel-openings by suitable molding, b, and G aretthe removable panels. The panels have rabbets or shouldersc at their edges overlapping the frame around the panel-opening, and the body of the panel which ts inside the panel-opening is made slightly narrower than said opening, so as to permit the panel to move sidewise siifiiciently to release the clamps D at one side of the panel. The clamps D are preferably made of flat bars or strips of metal, and are secured to the panel by the clamp-screws d and the retaining-screws d, the latter serving to hold the clamp-bars in place when the former are loosened. These clamp -bars should extend entirely across the panels, so as to strengthen them and prevent their warping. The ends of the clamp-bars project beyond the inside shoulders, c', of the panel sufficiently to properly engage the mortises or recesses a in the frame. The projecting ends of the clampbars should be longer and the recesses c deeper upon one side of the panel than upon the other, as illustra-ted in Figs. 3 and 4f, so that the panel may be readily applied and removed. The back of the panel is beveled or cut away slightly under the elamp-bars near the edges, so as to permit the clamp-screws d to tighten the clamps upon that portion of the frame embraced between the outer edges or shoulders, e, of the panel andthe clamps D. This beveled surfaceis conveniently made by eutting gradually-deepcning grooves cl across the back cf the panel, near the edges of the same. As an additional security, at the ends of the panels, especially when they are very wide, I provide revolving catches or clamps d2, riveted or rigidly secured to the screws d, which extend through the panel, so that by partially' turning said screws the clamps d may be made to engage suitable recesses in the frame. These revolving clamps will, however, ordinarily not be required, as the clamp bars D so strengthen and brace the panel that there is little danger of its warping or getting out of shape, whatever its width..

The preferable mode of practicing my invention is, as above described, to secure the clampbars permanently and rigidly to the panels, so that by simply loosening the clampscrews and sliding the panel to one side it may be removed; but it is obvious that by taking the clamp-screws d entirely out the clamp-bars D may be iirst put in place across the panel@ opening, and the panel then applied and secured in place by the clamp-screws. In this construction the body of the panel may of course be made the full width of the panelopening. It should be remarked that in this construction the retainingserews d would of course be omitted.

I claim- 1. The combination of door-frame A with screens D, removable panels C, having the body portions thereof narrower than thepanel-openings in said frame, and clamps D, immovably attached to said panels for securing said panels to said frame, substantially as specified.

2. The combination of door-frame A with screens B, removable panels C, and clamp-bars D, extending across said panels and engaging in mortises or recesses in said frame, substantially as specified.

3. The combination of door-frame A, provided witli mortises or recesses a,witl1 screens B, removable panels C, and clamp-bars D,

having clampscrews d, substantially as specified.

4.' The combination, with door-frame A, having recesses a, of screens B, clamp-bars D, extending across the panel-openings in said frame and engaging said recesses, removable panels C, having inclined or beveled surfaces near its edges under said clamp-bars, and clamp-screws d, substantially as specified.

5. The combination of frame A, having recesses a, with screens B, clamp-bars D, removable panels C, clamp-screws d, and revolving clamps d2 cl3, substantially as specified.

CHARLES ANDERSON.
