SPECIFICATIONforming part of Letters Patent No. 404,179, dated May 28, .1889.

Application filed July 11, 1888- To all whom it may concern.-

Be it known that I, GUsTAv JosEF DoL- LINER, manufacturer, of Hamburg, in the Free State of Hamburg/and German Empire, have invented a new and useful Improvement in Hinged Casements, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an apparatus for opening Windows outside and inside of the room.-

Figure l shows a view of the improved window as seenl from the inside. Fig. 2 is a crosssection through the window along the line X X of Fig. 1. Fig. 3 Ais a horizontal section taken through the window in the direction of the lines Y Y of fFig. 1, with one easement opened outward. Fig. 4 likewise shows a horizontal section taken along the line YY of Fig. 1, with one easement of the improved window when the lower window grooved bar, a, is taken out and the easement b is opened inward. Fig. 5 shows, on a larger scale, a section. taken through the double hinge g of the easement. Fig. 6 shows, on a larger scale, the special construction of the sockets c and e of this double hinge in such a position that the slanting edges d b', running one upon the other, are just lying together, a position which the parts assume when the window is closed or opened outward. Fig. 7 shows the position of the parts of the hinge, Fig. 6, at right angles to the position of Fig. 6. Fig. 8 shows the boxes or sockets of the hinge parts when the upper part, c, thereof is slid down on the incline d of the lower socket, e, so that the easement-is lowered to the height of its edge f down on the easement, Fig. 2, a position which is assumed when the Window is opened inward.

The object of this invention, hereinafter described, is to make windows in such a way that they can be opened both inward and outward, butkat the same time to combine this possibility with the condition of obtaining a tight connection between the Window-frame and the closed-Window easements. In order to attain thisy purpose, each of the easements has two separate points of rotation, and in addition the double hinges of the easements are so made that the easements when opened Serial No. 279,663. (No model.)

inward descend and the lower window-bar is made to take olf, so that the `easement provided with a strip at its bottom can be drawn inward through the space thus cleared.

The easements b b are-attached to the window-frames h h by double hinges g g. The window-frame h h has at the bottom grooved surfaces e' i, on which th'e lower window-bar, v a, is laid. The regular or irregular grooves 'i 6o serve to prevent as much as'possible the draft getting into the room.

The lower window grooved bar, a, is made of two parts, a2 a3, which are also provided with grooves at their corresponding adjoining edges and fit into each other toothwise, so that the entrance of draft is prevented. The lower Window-bar .has two curved ends, a4, which fit int-o sockets in the Window-frame h. In this way a secure and excellent air-` 7otight and easily-separable connection between the window-bars is obtained. a5 is an appliance for holding one easement so that the closed easements cannot ily outward.

The veasements are, as already stated, attached to the window-frames by'double hinges g g g g. The double hinges are shown on alarge scale in Figs. 5 to 8. One ange of the hinge is attached to the inner side of the casement at g. The other flange, g2, runs in a 8o bent form to the outer side of the windowframe h, and there rotates.` about the hingeflange g3, fastened to the window-frame.

If now one easement is to bc opened, it is turned about g3 and pressed outward, so that 85 it comes into the position shown .in Fig.

If both the easements of one windoware thus moved outward, it is easyto take out the' lower window-bar, a., separated into its two; parts, a2 ai. If it is now desired to open the. 9o

windows inward, they are turned about the.v i

part g', as shown in Fig. 4, and they can their' be opened inward.4 'The hinge parts g', with which the double hinges g areattaehed to the windows, have tubular sockets c, Figs. 6 to S, 95 which for the greater part of their circumference are cut off oblquely or spil-ally. 'lhe same applies to the tubular sockets e of the hinge parts g2, eut off obliquely at d. The

object of this arrangement is to lower the roo window to av certain extent while turning about the hinge g', the said extent being l ward-turned easement just what the flange f amounts to on the casement. As appears from Figs. 1 and 2, the easements are provided at f and k with strips or flanges, the object of vwhich is to effect a secure air-tight closure of the window against the window-frame or lower window-bar, a. The height of the upper flange, f, and the descent of the easementon the oblique surface d are less than the space between the strip k and the grooves t', so that when the easement' the flange f of the window moved inward 'comes and lies inside the window-frame h.

The inward movement of the easement is thus, in spite of the arrangement of the flanges f and k, rendered possible as soon as the lower window-bar, a, is taken out of the window-frame.

In orderi to prevent water from'eollecting on the windows and running down them into the lower bar, a, and also to prevent the ease ments in winter from being frozen in, a lip,

I, is fitted to the inside of the window-case ments below the paires, which catches the water and prevents its running ldown into the lower grooved bar. i

Between the easement and the Windowframe or the lower window-bar india-rubber or other packing can be placed for the purpose of tightening the easements.

What I claim, and desire to secure by Letters Patent of the United States, is

1.' The combination of a double-acting hinge, one of whose joints or hinge-points is made with spiral or inclined bearings, a easement hinged thereto, and a removable bottom strip arranged in the opening at the bottom of the easement for the latter to close against, substantially as and for the purpose described.

2. The combination of a double-acting hinge having inclined bearings at one of its articulations, a easement hinged thereto, a removable bottom strip for the lower part of the casement to bear against, and a lip, l, attached to the lower part of the easementv and overhanging the removablel bottom strip to catch the condensed water on the easement, substantially as and for the purpose described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
