Specification of Letters Patent. i

Patented May` 24, 1921.

Application led October 11, 1920. Serial No.`@416,114.

To all zn/wm t may concern:

Be it known that I, HARRY P. I-IoMERs, al citizen of the UnitedStates, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in IVindow-Sashes; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same.

This invention relates to an improvement in window sashes and particularly to sashes which are hung from the bottom rail and which are adapted to tilt forward to provide for ventilation and to permit the sash to be reversed in position. l/Vhat are known as bottom-hung sashes have been employed and adapted to swing forward at their upper ends to provide for ventilation, but some stop or device is necessary to arrest said forward movement of the upper edge of the sash to prevent danger of breaking by the falling of the sash. Means have been provided to limit the forward movement of the sashes and the obj ect of this invention is to provide means for arresting the forward movement of the sash and yet permitting it to be turned when required, and the invention consists in the construction and arrangement of parts as will be hereinafter described and particularly recited in the claims.

Reference is made to the accompanying drawings representing in-- Figure 1 a front view of a window provided with a sash hung in accordance wit my invention;

Fig. 2 a sectional view on the line 2-2 of Fig. l, enlarged;

Fig. 3 a similar view with the upper edge of the lower sash moved forward;

Fig. i a sectional view on the line 4-4 of Fig. 1;

Fig. 5 a perspective view of the locking lever detached;

Fig. 6 a perspective view of the stop plate detached;

Fig. 7 a broken sectional detail view illustrating the pin to limit the movement of the stop lever.

In carrying out my invention I employ the usual sash consistingof the lower rail 10, the upper rail 11, and side rails 12 and 13. Secured to the side rails near their lower ends are chains or cords le which are connected with the usual window weights for balancing the sash. This sash is adapted to be moved vertically in the usual guideways and held in place by stops 16 and 17, which are hinged at their forward edges to the window casing 18 so that they may be turned outward to give clearance to the lower sash. To prevent the upper edge of the sash from moving forward farther than desired I provide the edge with a plate 19 formed with a series of projecting stops 20, 21 and 22, more or less in number. These stops are adapted to be engaged by a lug 23 formed at the lower end of a lever 24- pivotally mounted on a plate 25 secured in the window 'casing above the upper sash rail 11 when that is in its lowermost position.` At the upper forward corner of the plate 25 is a hole 26 through which a pin 27 extends, this pin being projected outward by a spring 28 located in a socket 29 formed in the window casing 18. 'Io separate the meeting rails of the sashes to provide for ventilation, the stops 16 and 17 will be opened and as the sash is hung from the bottom the upper part will tend to drop forward, and as it moves forward it is caught by the engagement of the lug 23 with the stop 20. If furtherV movement is required, the lever 24: is swung outward so that the lug 23 may engage with the stops 21 or 22, beyond which the lever 24 cannot be moved, as it will engage with the pin 27. TWhen, however, the window washer desires to reverse the sash, it is only necessary to push the pin 27 inward, allowing the lever 24 to be entirely disengaged from the sash, which is then free to be reversed end for end. To prevent the lever 24 from engaging with the stop plate as the sash is moved up or down, I provide a stud 81 which limits the inward-swinging movement of the lever 24. I thus provide a simple and convenient means for holding a window sash in a partly open position and provide means to prevent its accidental opening adapted to engage with the stops on the said sftop plate or be entirely disengaged thererom.

2. The combination with e bottom-hung` window sash of a. stop plate secured at thev upper end of oneside thereof7 said stop plate formed with e series of stops, a plate secured to the window casing, e lever pivotally connected with said plete7 provided at its lower end with a lug adapted to engage with the stops on the said stop plate, seid lever pla-te also formed with an opening at its forward upper end, and aspring Vpin projecting outward through seid opening.

In testimony whereof, I have signed this speeilioation in the presence of two subscrib- Aing witnesses.
