WINDOW.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed June 17, 1905. Serial No. 265,827.

To all whom it nuty concern:

Be it known that we, FRANZ J. CARL, a citizen of the United States, and HERMANN G. CARL, a subject of the German Emperor, re-

siding in the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Windows, of which the following is a specification.

This invention is an improvement upon the construction of windows set forth in our Patents No. 741,457, of October 13, 1903, and No. 778,565, of December 27, 1904.

The invention applies to the same kind of windows as those shown in the patents namely, windows where both the upper and lower sashes are movable vertically and also capable of swingingand the nature of the present improvement is fully set forth below and also illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a window embodying our invention. Figs. 2, 3, and 4 are sections upon the lines 2 2, 3 3, and 4 4, respectively, of Fig. 1, Fig. 4 being enlarged. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 is an enlarged view of a portion of Fig. 3.. Figs. 7 and 8 are detached views of the lower and upper sash, respectively. Fig. 9 is a detail view.

In the drawings, 15 represents the windowcasing; 16, the upper sash; 17, the lower sash; 18, the balanceaveight of the upper sash, and 19 the balance-weight of the lower sash. The weights are connected to the sashes by cords passing over pulleys in the usual manner. Only one weight is used with either sash in order that one side of each may be free to swing open without detaching any sash-cord. Each sash is also provided on the side to which the sash-cord is attached with hinging devices. In the case of the upper sash, eyes 20 and 21, the opening through which is vertical, are secured one to the top rail and the other to the meeting-rail, and the casing is provided with a pivot 22, adapted to enter the eye 20 when the sash is lowered, and with a pivot 23, adapted to enter the eye 21 when the sash is raised. The casing is further provided with a pivot 24, adapted to enter the eye 21 when the sash is in its lowest position. In the swinging of the upper sash it is supported upon the pivots 22 and 24. The casing is grooved to give room to the weightchain of the sash on one side at 70, and it is also grooved upon the opposite side at 71 to give room or form a way for the antifriction-pulley 25 and a Wedge 26, which are attached to the edge of the upper sash and project therefrom into the casing-groove, the side of the groove 71 being cut away at points opposite the roller and the wedge when the sash is lowered to its swinging position. At its top the upper sash is provided with a socket adapted to receive a depending wedge 27, attached to the casing. The entrance of this wedge into the socket creates such friction as to hold the sash up and also presses it 0%osely against the casing and prevents ratt ing.

The lower sash is hinged at the opposite side of the casing from the upper one, and it carries the upper pivot 30 and the eye 31 of its lower hinge. The casing supports the eye 32 of the upper hinge and the pivot 33 of the lower hinge. Both pivots of the lower sash have considerable length, as will be noted, so as to permit it to be raised against the stop 40, attached to the casing, as and for the pur pose hereinafter fully explained. Upon its swinging edge the lower sash is provided with an antifriction-pulley 41 and also with two movable wedges 42 and 43, adapted to coact with the stationary cams or inclines 44 and 45, secured to the casing, in holding the sash against vibration or rattling. For locking the lower sash in its closed position I provide a stop 46, adapted to be inserted by hand in an opening 47 in the adjacent part of the casing. The guide-strip 48 at the inner side of the groove in which the guide-pulley and wedges travel is cut away opposite the positions occupied by the roller and wedges when the sash is in its swinging position, as shown at 49 and 50.

hen the sash is to be swung open, it is necessarily raised sufiiciently to enable it to avoid interference with the window-sill 51, and in order to limit this raising movement, so that the roller and wedges may not pass beyond the openings provided for them in the guide-strip and also so the sash may not move far enough to separate pivot 30 from eye 32 or eye 31 from pivot 33, the stop 40 is secured to the casing at the point indicated, so it may arrest the upward movement by its contact with the upper pivot. This stop is that movement.

gravity and arrests the upward movement, as stated; but it may be thrown out of service entirely by turning it to its non-acting position and then by tightening the screw, so as to prevent its swinging automatically. The body of the stop is flush with the surface of the casing, but does not project far enough to encounter the sashpivots, and it may be provided with an attaching-plate sunken within the casing, this being the construction shown. The two sashes may be locked together by any suitable fastenersuch, for instance, as that shown at 54. The stop 46 is preferably provided with a chain upon which it may be suspended when taken out of its acting position.

Our window is provided with a screen 60, which is adapted to serve its purpose with either the upper or the lower portion of the window open. It is vertically movable, having flanges 61 and 62 on its side edges entering and traveling in grooves 63 and 64 in the casing, and is provided with one or more lockingbolts 65, adapted to lock the screen in its different positions. We prefer to make the screen removable when in its lower position by deepening the channels 63 and 64, so that by moving the screen when in that position toward either side the flange on the opposite side will be freed from its guide-channel, and in order that the screen may not get so far to one side as to free it from its guide-channels when that result is not desired we place springs 66 in the channels, which restrain the screen from this sidewise movement. The upper part of channel 63 is partially filled as, for instance, by the blocks 67, having inward movement of the lower sash preparatory to swinging it open, and adapted to be moved out of the way of the sash at will and also adapted to be moved out of the way by the sash when descending.

' 2. The combination with the verticallysliding and horizontally-swinging sash, of a freely-swinging stop 40 having an outstanding rib normally in position to arrest the upward movement of the lower sash preparatory to swinging it open and adapted to be moved out of the way of the sash at will and also adapted to be moved out of the way by the sash when descending.

3. The combination with the vertically sliding and horizontally-swinging sash, of a freely-swinging stop 40 normally in position to arrest the upward movement of the lower sash and adapted to be moved out of the way of the sash at will, said stop being also pro vided with an inclined surface whereby the sash may when moving down automatically swing the stop out of the way.
