HORIZONTAL LY-SLIDING WINDOW, DOOR, OR THE LIKE.

SPECIFICATION forming part of Letters IPatent No. 520,713,dated May 29, 1894.

Application filed October 31, 1893. Serial No. 489,605. (No model.)

To all whom it may concern:

Be it known that I, CARL S'tiMMERMANN, architect to the board of trade, of Munster, Westphalia, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in I-Iorizontally-Sliding Windows, Doors, or the Like, of which the 7 following is a specification, reference being had therein to the accompanying drawings.

It is well known that the methods of window closing hitherto in use are far from being perfect and many attempts have been made to remedy their defects. It has been suggested to construct windows, doors and the like, to slide horizontally and to do away with the ordinaryhinges, but the disadvantage resulting from this construction was that they Were not air-tight.

The object of the present invention is to provide a horizontally sliding and air-tight closing sash, casement or door for windows, doors, shutters and the like, which may be opened by a simple manipulation and, in the case of windows, without the slightest interference with the curtains or with any object placed on the window sill, and which is airtight when closed.

The invention will be more fully understood by reference to the accompanying drawings, in which Figure l is a front view of a window. Fig. 2 is a horizontal section of the same drawn on the line C D, Fig. 1. Fig. 3 is a vertical section drawn on the line A B Fig. 2. Fig. 4 is a broken section drawn on the line C D, Fig. 1, on an enlarged scale, the window being closed. Fig. 5 is a similar view to that represented in Fig. 4 but with the window incompletely closed. Fig. 6 is a broken section drawn on th'elineE F Fig. 1, showing a means for rendering the windowair-tight by raising it, the window being shown in this figure as not having been yet lifted. Fig. 7 is a similar sectional view but showing the window lifted up. Fig. 8 is a broken section drawn on the line E F, Fig. 1, showing a method of excluding the draft by lowering the window but with the window not yet lowered. Fig. 9 is a similar section to Fig. 8 but showing the window lowered.

The horizontally sliding sashes, easements, doors or the like, are supported in a suitable manner by means of rollers, balls or carriers, which may be arranged either at the top or at the bottom of the said sashes, casements or doors, and allow of the same to be moved easily and without much friction, and it is only at the last moment that the sashes, casements or doors are rendered air-tight by either a lifting or lowering movement accompanied by either an inward or outward movement of the sash, casement or door. The sash, casement or door is provided with a suitable handle h by which it may be moved.

The drawings represent a window sash suspended from rollers. The window sash r is for this purpose provided with supporting bars Z adapted to form bearings forthe pins 2 of the suspension rollers 0 which latter run on rails s so as to enable the sash to be moved easily. The said rails may be made of angle iron or other suitable material and are provided at the part where the rollers rest when the window is closed with either a raised portion as represented in Figs. 6 and 7 or with a depressed portion as represented I in Figs. 8 and 9. The two different levels of the rails are of course provided with an inclined portion between them to enable the roller to pass easily from one to the other. Besides the difference in the level of the rails, the running edge is bent either toward or away from the window frame, as shown in Figs. 7 and 9, at the portion coinciding with the raised or depressed portion mentioned before.

The edges of the sashes are provided with inclined surfaces or grooves, which form, in conjunction with similar inclined surfaces or grooves provided on the window frame, an airtight joint.

Figs. land 5 show joints of the aforesaid description in closed and in open position respectively. The window sash is in this case provided with an inclined protruding edge n, which'fits a similarly formed groove is formed in the window frame. A crossbar q fixed to the opposite edge of the window sash is provided with an inclined groove on on one side and with an inclined surface f on the other side, which, in conjunction with a wedge shaped rail Z and an inclined surface 0 rethe window.

In the arrangement represented in Figs. 6 and 7, where the window sash is rendered airtight by a lifting movement, the arrangement is as follows: The upper edge of the window sash is provided with inclined surfaces j and g which are respectively brought into contact with an inclined groove 1) and an inclined surface (1 so as to form a tight joint. The lower edge of the sash is pro- 10 vided with two extensions a and b, a being bent at an angle in such manner that when in contact with the inclined part of the middle piece 25, an airtight joint is also formed betweena and b. If the tight joint is formed I 5 through the lowering of the window as represented in Figs. 8 and 9, the arrangement adopted is very similar-to the one just de scribed. The upper edge of the sash is provided with a groove to and an inclined sur- 2o face z'engaging respectively with the inclined edge a: and inclined surface y on the window frame, which parts, when in contact, form a tight joint, while the extensions U r; at the lower edge of the sash are simply straight,

the intermediate piece to forming the tight joint.

In addition to forming the tight joints as before described by means of Wedging surfaces and grooves, it is desirable to force the 0 sashes in the one or the other direction against the window frame. This may be done on the one hand by bending the running rails of the rollers at their raised or depressed portions either toward or away from the window frame in order to bring the otherwise loosely suspended sash against the window frame. On the other hand the arrangement adopted with the wedge shaped grooves and surfaces draws the sash in the one or the other direction against the window frame and thereby increases its elfect.

It is only a matter of construction to apply the invention, as illustrated by way of example in the accompanying drawings, to doors,

blinds and the like, the principle involved being to form a tight joint all round through the lifting or lowering of the sash or door ac companied by a lateral movement, which principle may be carried into practice by the means hereinbefore described.

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

1. In a sliding door, window or the like, the combination, with the frame and the sliding sash, of an essentially horizontal guideway on which the sash is adapted to travel, said guideway having portions that deviate both vertically and laterally from the main portion of the guideway, whereby the sash is moved both vertically and transversely to the guideway when the door or window is nearly closed to bring the sash tightly against the frame, substantially as described.

2. An arrangement for producing tight joints in horizontally sliding sashes, doors and the like for windows, doors and the like, consisting of means whereby the sliding sash, casement or door, when nearly in its closed position is varied in elevation through the difference in the level of the guide rail or rails on which the suspending rollers run, while at the same time a horizontal deviation of the rail in conjunction with inclined wedge shaped surfaces at the top, bottom and sides of the sash, door and the like, causes the sash, door or the like to be forced tightly against the frame substantially as described.

3. In a sliding door, window or the like, the combination, with the frame and the sliding sash, of an essentially horizontal guideway on which the sash is adapted to travel, said.

guideway having vertical deviations for moving the sash vertically, inclines at the top, bottom and sides of the sash, and projections on the frame for engaging each of the said inclines to move the sash transversely to the guideway, as and for the purpose set forth.

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