Application filed March 22, 1900. serial No. 9,755. L1 lo model.) i
To all whom, it mag concern:
Be it known that I, GEORGE W. HOLLY, a citizen of the United States, residing at Palo Alto, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification.
This invention relates to new and useful improvements in window sashes and screens; and its primary object is to provide a device of this character which is cheap and durable, which may be readily reversed for cleaning or other purposes without removing the same from the window-frame,aud which may be easily removed without disturbing the weights, cords, or molding.
To this end the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a view of a portion of my improved sash broken awayand partially in section to show the parts. Fig. 2 is a top plan view of a portion of thesash mounted within a window-frame shown in section, and Fig. '3 is a horizontal section through a portion of the device.
Referring to said figures by numerals of reference, 1 is a sash of ordinary construction pivotally mounted within a three-sided subsash 2, having a recess 3 therein at each side for the reception of a pivot-pin 4, passing through the sash and engaging with a nut 5, embedded in the sash and secured thereto in any suitable manner, as by means of screws. Subsash 2 is hung within the window-frame in the usual manner, as by means of cords and weights, and may be moved freely up and down therein.
Within the inner surface of each upright portion of the subsash is formed a longitudinally-extending groove 6, adapted to receive a sliding tongue or strip 7, mounted in a corresponding groove 8, formed in the adjacent edge of the sash 1. This slide is provided near each end with a curved slot 9, into which projects a pin 10, fixed within the groove in any suitable manner.
Pivotally secured to the tongue 7, near the upper end thereof, is a link 11, pivoted at its opposite end to a sliding plate 12,- mounted upon the upper-edge of the sash 1 and adapted to close the ends of the slots 6 and8. This slide is mounted in suitable guides 13, se-
cured to said sash, and is provided with a knob 14, adapted to project through an opening formed in one arm of a bell-crank lever 15, pivoted to a bracket 16, secured to the upper end of the subsash 2. The oppositelyextending arm of the lever is preferably provided at its end with a knob or enlargement 17, adapted to swing back into a recess 18, formed in the window frame or casing 19.
In operation when it is desired to reverse the sash it is merely necessary to swing the lever 15 back from the knob 14, permitting the slide 12 to be drawn back in the guides 13 thereof. This movement will ,draw the tongue 7 upward and backward, as is obvious, withdrawing the same from engagement with the subsash 2. The sash may then be swung upon its pivots 4:, as is obvious. When it is desired to again secure the sash within the subsash, the slide 12 is drawn forward, thereby sliding the tongue 7 into the slot 6 of the subsash and locking the two firmly together. The lever 15 may then be placed over the knob 14, and thereby prevent accidental movement of the slide.
When it is desired to entirely remove the sash from its subsash, all that is necessary is to retract the tongue 7, as before described, and unscrew the pivot-pins 4.
By throwing the upper arm of the lever 15 into engagement with the window-casing the subsash is prevented from being moved upward by the sash-weights when the sash is removed.
It will be understood that the tongues also serve to exclude all air, rain, &c.
While I have shown and described my invention as applied to an ordinary windowsash, I do not limit myself thereto, as the same is applicable equally as well to screens, 8m; nor do I limit myself to the use of a single tongue 7, as, if desired, one may be mounted within each side of the sash 1.
Having thus fully described my invention,
ing the same in closed position, a slide for operating the tongue, and a lever pivoted to the subsash and adapted to engage said slide and the Window-casing alternately.
3. In a device of the character described the combination with a subsash, of a sash pivotally secured therein, a tongue slidably mounted within the sash and adapted to engage said subsash, curved slots within the tongue, guide-pins therein, a slide upon the sash having a link connection with the tongue, a knob to said slide, and a bell-crank lever having an opening therein adapted to receive the knob, whereby the slide is locked in position.
4:- In a device of the character described the combination with a window-casing having a recess therein, of a subsash slidably mountedwithin the casing, a sash pivotally secured Within the subsash, a slotted tongue slidably mounted within the sash and adapted to engage the subsash, guide-pins in said slots, a slide, a link connection between the tongue and slide, a knob to the slide, and a bell-crank lever having an opening in one arm thereof adapted to receive the knob, said .lever normally engaging either the knob or the recess in the window-casing.
In testimony whereof I aiffix my signature in presence of two witnesses.
