WINDOW.

SPECIFICATION forming part of Letters Patent No. 722,533, dated March 10, 1903. Application filed December 4, 1902- Serial No. I331878. (N model- To all whom it may concern:

Be it known that 1,,FRANK NENTWICH, a citizen of the United States of America, residing at East Liverpool, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Windows, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in windows, and has for its object to construct a window in which both the upper and thelower sash may be swung inwardly, so as to facilitate the cleaning, and [5 also to provide novel means for locking the sash at any desired height and to dispense with the sash cords and weights as ordinarily employed in connection with windows, which are automatically held at the desired positions.

In describing the invention in detail reference is bad to the accompanying drawings, forming a part of this'specification, and wherein like numerals of reference indicate like parts throughout the severalviews,inwhich Figure 1 is a central vertical sectional View of the window constructed in accordance with my invention. Fig. 2 isoa rear perspective view showing the manner in which the. sash are swung inwardly to facilitate the cleaning. Fig. 3 is a front elevation of the upper sash, partly broken away to show the means for holding the same at any desired position.

Fig. 4 is an elevation, partly broken away,

3 5 of the lower sash, showing the means for holding the sash at any desired position. Fig. 5.

is a horizontal sectional view of one of the rack-bars which are mounted in the windowframe, at one side thereof, and to which the windows are hinged. Fig. 6 is a horizontal sectional view through the frame with the sash removed.

In the accompanying drawings, illustrating my invention, 1 indicates the window-sill, 2 5 and 3 the respective sides of the frame, and 4 the top thereof. lhe frame also comprises front strips 5,'rear strips 6, and intermediate strips 7, the sash sliding between the strips 5 7 and 6 7. The sash are arranged so that they may be forced laterally toward one side of the frame in order to disengage the same from between the sliding-rails at the oppo- "dow.

site side of the frame and permit of said sash being swung inwardly in order to facilitate the cleaning of the windows when desired. Between the strips 5 7 and strips 6 7, adjacent to the side 2 of the frame, are arranged rack-bars 8, which are provided with a rackface 9 and in the face, adjacent to the front of the window, are provided with a groove or seat 10, placed adjacent to one edge of the rack-bar and adapted to receive the hinged rod 11. This hinged rod 11 passes through sleeves or keepers 12, carried by the lower sash 14 and also by the upper sash 15. Springs 17 are attached to the rear face of the rackbars 18 and to the side 2, as seen in Fig. 1 of the drawings, and serve to hold the rack-bars pressed normally outward toward the win- At the opposite side of the frame, between the strips-'5 7 and strips 6 7, are arranged stationary rack-bars 18. The sleeves 12 and the rods 11 form a hinge connection between the sash-rail of one side of the sash and the vertical rack-bars 8. The frame is provided at its upper end-at the-front portion thereof -with a recess 19, closed by the I bottom 20,110 which is affixed the spring 21, having bowed ends which bear against the underneath face of the top 4. In order to swing out the upper window 15 toward the front of the window to facilitate the cleaning, I force the lower sash 14 upwardly, the mid-rail 22 engaging the strip 20, compressing the spring 21 and allowing the upper end of the sash 14 to enter the recess 19. The upper sash 15 may then be pulleddownwardly until its top rail clears the lower mid-rails of the sash l4 and its lower rails clear the sill 1 of the frame, at which time the said upper sash,

which has now been pulled down to the lower part of the frame, may be swung inwardly .inorder that the window may be readily cleansed. V

Means is provided for engagement with the locking- bars 8 and 18 to lock the 'sasheither in the closed or partially-opened position. This means for the upper sash 15 I have shown as comprising two locking-rods 23, the ends of which project normally beyond the side walls of the sash and engage in the racks 9 of the rack- bars 8 and 18. These locking rods operate in ways 24, provided therefor in the lower mid-rail 25 of the upper sash 15,

this mid-rail having a recess 26 therein in which is pivoted a pair of levers 27, which are connected by short links 28 to the locking-rods 2,3. A plate 24 is secured to the sash and closes the ways 24 at the lower side. The bow-spring 29 is connected to the pivotpins 29, which fasten the links 28 to the locking-rods 23, and thus normally hold the rods 23 in the extended position, this spring being doubled as the two levers 27 are drawn toward each other. For locking the lower sash I provide the lower mid-rail 30 with inclined ways 31, through which extend the locking-rods 32, the other ends of the latter projecting normally beyond the side rails of the sash and the inner ends of these rods being pivotally connected to links 33, that are in turn connected to links 34, the latter being attached at their upper ends to the pivot-pin 35, carried by the thumb-piece 36, which operates vertically in back of a plate 37, which is arranged in the recess 38 in the lower sash-rail 30. It will be observed that as the thumbpiece 36 is depressed the lower ends of the links or levers 34 will be spread apart, while the upper ends of the links 33 will be moved toward each other, thus retracting the locking-rods 32 out of engagement with the rackbars 8 and 18 and permit the vertical movement to be imparted to the sash 14. The locking-rods are held normally in engagement with the rack-bars by means of the bow-spring 40, which is connected to the pivoted pins which fasten the links 33 to the locking-rods 32. A suitable catch 39 is carried by the lower sash-rail 30 in order to facilitate the raising of the window. It will be observed that when the thumb-piece 36 is depressed and the locking-rods 32 turned so as to be disengaged from the rack-bars, the lower sash will be free to be moved up and down in the frame, as desired; also, that when the levers 27 are drawn toward each other the locking-rods 23 'will be retracted and the upper sash is free to be moved up and down, the sleeves 12 of both sash sliding upon the vertical hinged rod 11. When it is desired toswingthe sash inwardly for the purpose of cleaning, the lower sash 14 is moved laterally, so as to depress the spring 17, forcing the rack-bar 8 within the frame until the opposite end of the sash is free of the slide-rails 5 and 7. The sash may then be swung inwardly on its hinge, so that ready access may be had to either side of the glass. In order to swing the upper sash inwardly, the lower sash 14 is elevated until its upper end is within the recess 19, and the upper sash is then pulled downwardly and moved laterally, so as to press its locking-bar 8 in order to clear the opposite side of the shaft from between the slide-rails 6 7, and this upper sash may then be swung inwardly in the same manner as was done with the lower sash.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a window-frame, spring-pressed rack-bars arranged in the frame at one side thereof, a pair of sash hinged to said rack-bars, and means for locking said sash at difierent positions in the frame, substantially as described.

2. In combination with a window-frame, spring-pressed rack-bars arranged in the frame at the side thereof, stationary rackbars arranged in the frame at the opposite side thereof, a pair of sash hinged to the spring-pressed rack-bars, and means for looking the sash at different positions, substantially as described.

3. In combination with a window-frame, a

pair of spring-pressed rack-bars arranged in the frame at the side thereof, a pair of sash hinged to said rack-bars, and having sliding movement independent of the rack-bars, stationary rack-bars arranged in the opposite side of the window-frame, and locking means for engagement with said rack-bars to hold the sash at diiferent positions, substantially as described.

4. In combination with a window-frame, a pair of spring-pressed rack-bars arranged in one side of the frame, and having grooves in one face, verticalrods mounted in said grooves, a pair of sash carrying sleeves or keepers to receive said rod whereby the sash are hinged to the rack-bars to have a sliding movementindependentof the bars,and means for locking the sash at different positions, substantially as described.

5. In combination with a window-frame having a recess at its upper end, a pair of spring-pressed rack-bars arranged in one side of the window-frame, a pair of sash hinged to the rack-bars and having a sliding movement independent of the bars, one of said sash adapted to partially enter the recess at the top of the frame when elevated, the other of said sash adapted to clear the first-named sash when lowered whereby both sash may be swung inwardly, and means for locking the sash at dilferent positions, substantially as described.

In testimony whereof I aftix my signature in the presence of two witnesses.
