WINDOW.

SPECIFICATION forming partof Letters Patent No. 509,521, dated November 2S, 1893.

Application filed April 28, 1893.

To a/ZZ whom t may concern.-

` Be it known that I, OSCAR FRoTscHER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, 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 of that class in which provision is made for allowing the sliding sash to be swung out or reversed if desired for cleaning or other purposes, and it has for its objects among others to provide a window of this class which can be cheaply made, easily operated and not liable to get out of order.

It has for a further object to provide simple yet efficient means for holding the sash inclined for ventilation; and for a still further object the provision of means for firmly holding the sash in position for cleaning.

It aims further at certain improvements in the details of construction whereby better results are attained without increasing` the cost of construction or interfering with the employment of the Window in the ordinary.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a vertical section of a windowframe, with the sashesin position. Fig. 2 is a similar View, with the lowersash shown open for ventilation by full lines, and in dotted lines shown open for the purpose of cleaning. Fig. 3 is a like view with the upper sash open for cleaning, the dotted lines showing the said sash in position for introducing the means for holding it firmly in place, the attachment being shown by full lines in the position it assumes when extended. Fig. 4 is ahorizontal section through one side of the window with the upper sash indicated by dotted lines.

5o Fig. 5 shows in detail the means for holding the sash in its inclined position for cleaning.

SerialNo.472,212. (No model.)

Like letters of reference indicate like parts throughout the several views in which they occur.

Referring now to the details of the drawings by letter, A designates the window-frame, B, the upper, and G the lower sash. The sashes are adapted to slide in the ways in the frame and are hung upon the cords or chains l) and Weights E, the former running over the pulleys F arranged in the pulley stiles G in any well-known way. Each of the sashes is cut away or rabbeted on the sides adjoin ing the pulley stiles from about the middle or center ot' its height upward as indicated at a, preferably toward the outside of the window as shown best in Fig. 4:. Below this rabbet is a hole b to receive the cord or chain D which is knotted or fastened in any suitable manner. The lower sash is of usual size andis held in place bya stop-bead cwhich is divided on both sides of the window at a point somewhat above thetop of thelower sashandlhinge them to theframe in any suitable manneras by hinges d as seen in Figs. 3 and 4. The upper sash is somewhat narrower than the lower one as will be seen from Fig. 4:, and the space thus provided is occupied by the projection e which may be integral with the pulley stile, or it may be in the form of a cleat separate therefrom and secured thereto in any suit-` able manner as indicated by dotted lines in Fig. 4; in either form of construction it serves the same purpose. Making the pulley stile thicker than usual and rabbeting the same may be found the preferable way. A parting bead j is affixed to this projecting portion and extends from the bottom of the upper sash to the window bead as seen in Fig. 4f, projecting about as much as the usual parting strip projects from the frame.

The attachment of the cord or chain to the sash is preferably a little above the center of gravity of the sash so that it will have a tendency to revert to its normal position and at the same time will require but little exertion to hold it in the position for cleaning. The pulleys F are preferably of different sizes, the back pulleys being the thickness of the projection e wider than the front one; by this IOO positions in the boxes ot' the frame.

Against the head of the window frame in the plane of the upper sash I place a stripV g, and on the sill in the plane of the lower sash I place a strip h as seen clearly in Fig. l; the thicknesses of the two combined being somewhat greater than the thickness of the meeting rails so as to allow the upper sash to.move inward as indicated in Fig. 3. These strips may be independent pieces secured to the head and sill, or they maybe formed by making these parts of the frame of thicker wood and rabbeting the same; or the Whole thickness required may be located at the head of the window instead of part at the head and part at the sill, as may be found most expedient.

With the parts constructed and arranged substantially as above set forth the operation 'is as follows: The movable portions of the stop-bead are thrown out on their hinges into the position in which the one is shown in Fig. 3; the lower-sash can then be brought forward and taken-out of the groove or-way and can thenbe reversed on the cords by reason of the cut away portions, for cleaning the outside; when .returned to its normal position it can be slid upward inside of its groove or way. The upper sash can then be slid downward and at once brought forward out of its groove or wayas seen in Fig. 3. Owing to the sashes beingvcut away at the sides as indicated at c theycan beeasily reversed without withdrawingthem entirely out of the frame, whereas if they-were not cut away, it would be necessary to lift the cords out of the grooves in or-` der to draw out the sashes entirely-clear of thetrame before they could be reversed. The lower sash in order to swing inward more easily should .have the outer lower corners rounded oft slightly where they are in contact with the cleat or projection in the groove of the upper sash, as shown at n; as seen in detail at the right of Fig. 4t.

To lprevent the rubbing of the chains or cords against the wood in moving the sash inward I Vsecure a screw I at the corner of the xed inside stopbead vl and also at the corner of the parting strip at the lower end ot' the same, on both sides of the window; these screws are without projecting heads as seen in `Fig. 4.

In order to bring the lower sash inward and hold it in an inclined position as shown in Fig. 2 for ventilation I secure a plate J to the pulley stile so that it will hang loosely on eitheror both sides of the window; this plate is provided with a plurality of notches j and is pivoted on a screw or other suitable means `lait-being covered by the inside stop bead as seen in Fig. l, which is provided with a recess Z to receive it as shown in Fig. 3. This plate is beveled on the side of the notches and is adapted to be engaged over a pin or screw K secured to the side of the sash and thus the sash can be secured in as many positions as there are notches in the plate. In

bringing the sash in for cleaning this plate must, of course, be disengaged from the pin or screw.

In order to hold and support the sash in an inclined position for cleaning I have provided the following means: At one or both sides of the window I attach to the inside stop bead above the division a plate M tapped to receive a thumb screw, and to the side of each sash in the rabbet thereof a plate N with an elongated hole nas seen best in Fig. 5, where the plate N is shown detached. O and P are bars or strips each provided with an elongated slot o and p respectively as seen in Figs. 3 and 5, and mounted to slide in these slots is a thumb screw Q with a plate upon each side of the said strips to bind them together when the thumb screw is turned in the proper direction. One end ofthe plate or bar O isconnected to the plate M by a thumb screw m while one end of the bar or strip Pis provided with a casting R which has a crook r as seen best in Fig. 5 which is adapted toengage the elongated slot of the plate N. The operation of this part of the inventionis as follows: The

strips or bars being loosely connected bythe thumb screw in the slots thereof and the thumb screw mengaged with the plate M, thecrook is introduced into `the elongated `slot n of the plate N when the sash is brought inward as seen by dotted lines in Fig. 3. The sash is then brought inward to an Vangle of about forty-live degrees (450), and asthe sash is turned to bring it into this position, as soon asthe sash is turned from an upright position the crook turns in the slot and becomes so fixed that it cannot-be displaced or disengaged until the sash isbrought into its former position, parallel with thestrip P. When the sash has been Vbrought to an angle of about forty-tive degrees, as shown by full lines in Fig. 3, the thumb screwis tightened and the sash will thus be held firmly in that position.

S is an angle plate or iron secured-to one of the bars or strips as seen in Fig. 3, and

-when the bars are brought into the position in which they are shown by full linesin Fig.

3 it serves as a stop to prevent further movement of the bars and prevents one going beyond the other as will be readily understood vfrom reference to Fig. 3. The crook lr being in a-vertical plane about midway between the plates N of the upper and `lower sash can be used for either.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing anyof its-advantages.

Parts may be used without the whole. The supporting devices .may be used in connecltion with other constructions of window.

What I claim as new ism l. The combination with a window-frame, of two sashes of different widths, the upper sash being the narrower and each sash having its edge cut away for a portion of its IOC length, a projection between the narrow sash and the frame, and a movable stop bead in front of the bottom sash to provide a space below the upper sash for the withdrawal of the sash, substantially as specified.

2. The combination with a window-frame, of two sashes of dierent widths, the upper sash being the narrower and each sash having its edge cut away for a portion of its length, the sustaining cords attached to said sash near the end of the cut away portion, a projection between the narrow sash and the frame, a parting strip set in front of the upper Sash only and a movable stop bead oppo-V site the lower sash, substantially as and for the purpose specied.

3. The combination with a window frame havingV two sashes hung therein, the sashes and guides for the same being constructed to allow the top of the sashes to swing inward and downward, of a plate on the sill of the frame in line with the lower sash and a plate in the head of said frame in line with the upper sash, said upper sash being narrower than the lower sash and hung on two cords, one on each side, whereby the top of said sash may swing inward and downward on said cords, under the bottom of the lower sash when the latter is raised, substantially as described.

4. The combination with a sash mounted to swing, of means for holding the same in an inclined position, said means comprising two pivotally and adj ustably-connected slotted bars, screws passing through the slots for `adjusting them, and means for detachably 3 5 April, 1893.
