MEANSVFOR RAISING LOWERING WINDOWS.

SPECIFICATION forming part of Letters atent No. 652,394, dated June `26, 1900.

l Application iiled November 7,1899. Serial No. 736,1 S7. (No model.)

To all wtont t may concern:

Be it known that I, ALBERT LAGUS, a citi zen of the Empire of Austria-Hungary, residing at Prague-Karolinenthal, in the Kingdom of Bohemia, Austria-I-Iungary, have invented certain new and useful Improved Means for Raising or Lowering Windows and the Like, of which the following is a specification.

The present invention relates to a contrivance tor raising and lowering windows and the like and is especially adapted in connection with the sliding windows of carriages. For this purpose a lazy-tongs device connected with the window-frame is so arranged upon or within the lower or covered part ofthe door that it can be extended orcontracted at will by turning or moving an operating part or handle suitably arranged on the inner side of the door and within easy reach of the hand of the occupant, by which means the window may be raised or lowered.

The invention is illustrated, by way of example, as applied to a carriage-door.

Figure l is an elevation of the device, the outer or protecting portion of the door being removed. Fig. 2 is a transverse longitudinal section through the carriage-door, and Fig.

, 3 represents a detail of the operating mechanism. Figs. 4 and 5 are respectively a sectional and a front view relating to the stops for holding the win dow at different elevations.

In a groove a of the bottom bar b of the window-frame c are arranged plates c, connected to the two top members of a lazy-tongs s, and in contact with and running on the under side of said barb are rollers cl, connected to said members and intended to facilitate the movement of the lazy-tongs. The lazytongs are arranged between the double boarding of the carriage-door, and the two bottom members are also provided with rollers d', running on a rail or guide f.

The pin g, connecting the two hottomvmembers of the lazy-tongs, is securely connected with or inserted in a vertical bar or plate h, provided with a longitudinal slot i, in which are guided the central pivot-pins of the lazytongs. This guide-bar passes through the barfand rests at s on an arched or other spring j, the latter constantly tending to push the guide-bar upward, and with it the lazy- `ton gs s and the window-frame o, connected to the latter.

is arranged a crank device m n, which when .turned in one or the other direction will raise or lower the window. This crank device is arranged as follows: The axle m of the crank n passes through the inner board of the door,

mental disk o, provided with an eccentricallyfixed pin p. The pin p engages in ahorizontal groove q of a guide-block r, movable vertically in a recess t, provided for that purpose in the casing a, inclosing the actuatingdisk o, the guide-block r being pivotally connectzed with the guide-bar 71. by means of the pin f.

The device acts in the following manner when, say, the window is to be lowered or opened, in which case the handle n will be turned toward the left, Fig. 3. In this movement the segment-shaped plate o and the pin p participate, with the result that the guideblock r is pressed vertically downward, the latter carrying with it the guide-bar h. In the movement of the guide-bar, however, the lazy-tongs become involved, owing to the pin g connecting the two parts, and thus also the window-frame, which descends and occupies the position indicated in dotted lines, Fig. 2. When turning the handle in the opposite direct-ion, the movements of the various parts of the mechanism described are reversed, resulting in anupward movement of the window-frame, in which movement it is assisted by the effect of the spring j on the guidebar h.

In order to be able to tix the window at intermediate positions, several stops or catches dle on the inner part of the door, which stops give way when forced by the crank, but otherwise secure the latter, and with it the window, in the different corresponding positions. This mechanism is shown more particularly in Figs. 4 and 5. On a segmental plate 00, on which the crank-handle n is guided, several stops or catches c (three, for example) are arranged in the path of the crank-handle by means of suitable plate-springs y. By 'such arrangement the stops fu' will give way when On the upper end of the guide-barb at 1 Fig. 2, and is secured to the center of a sego are arranged in the path of the crank-han- IOC force is applied to the crank, and they will be moved into the space of the door in the direction of the arrow, Fig. 4. The position 1 of the crank-handle n shown in Fig. 5 corresponds to the closed position of the Window. If the crank-handle is moved between the stops 2 and 3, the window is opened a third of its stroke. It Will be understood that the stops are only moved by forcing the crankhandle n, but otherwise secure the latter, and with it the Window, in the different correspondin g positions.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Apparatus for raising and lowering windows by means of a lazy-tongs device operated by a crank-handle, comprising a pin, on a plate connected to the crank-handle, engaging with a vertically-movable guide-block connected to a vertical guide-bar to which the pivot-pin of the two bottom members of the 1azy-tongs is connected, substantially as described.

2. Apparatus for raising and lowering windows comprising a slotted guide-bar, a lazytongs device, the pivot-pin of the two lower members of which is connected thereto, rollers at the extremities of the end members of the lazy-tongs, a guide-block on said bar provided with a horizontal groove, a crank-plate with a pin engaging said groove, and a crankhandle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

`ALBERT LAGUS.
