WINDOW.

SPECIFICATION forming part of Letters Patent No. 785,778, dated March 28, 1905.

Application iled October 25,1902. Serial No. 128,791.

To all whom it may concern,.-

Beit known that l, CLINTON D. TABOR, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Windows` of which the following is a speciiication.

This invention relates more particularly to that type of windows which are known as "French-easement windows, in which the sash is pivoted on one of its vertical edges to the frame, so that it can be turned in a horizontal plane for opening and closing the same.

The objects of thisinvention are to provide improved means wherebyvthe sash is automatically and securely locked upon closing the same, to provide means whereby the sash the free end of the sash and the frame.

can be easily unlocked from the inside of the window for opening the same, and to provide efficient means for rendering the joints between the same and the frame practically water and dust proof.

In the accompanying drawings, consisting of four sheets, Figure l is an inside elevation of a French-easement window embodying my improvements. Fig. 2 is a vertical section, on an enlarged scale, in line 2 2, Fig. l, showing the sash closed. Fig. 3 is a similar section showing' the sash open. Fig. 4 is a vertical section in line l 4, Figs. l and 5, showing more particularly the weather-strip between Fig. 5 is a horizontal section in line 5 5, Fig. 2. Fig. 6 is a detached top plan View of the faceplate and connecting parts applied to the stool of the window-frame. Fig. 7 is a bottom plan view of one section of said plate and the sash-lifting lever mounted thereon. Fig. 8 is a fragmentary vertical section in line 8 8, Fig. 2. Fig. 9 is a vertical section at right angles to Fig. 8, taken in line 9 9 of the same.

Fig. l0 is a bottom plan View of the face-plate applied to the Linder side of the sash. Fig. l1 is a top plan view of one section of said last-mentioned face-plate and the lockingcatch mounted thereon. Fig. l2is ahorizontal section in line 12 12, Fig. 8.

Similar letters of reference indicate corresponding parts throughout the several views.

The frame of the window consists, essentially, of a lower horizontal sill A, an upper horizontal jamb or head A', and vertical side jambs A2 A3, connecting the head and sill.

B represents the sash, which tits into the frame and which is connected on one of its sides or stiles with the adjacent jamb of the frameby hinges 6. These hinges are so constructed that the sash can swing in a horizontal plane for opening and closing the same and also slide vertically for locking or unlocking the same. The ordinary butt-hinge, in which the eye on one leaf is capable of turning and sliding on the pintle of the other leaf, answers this purpose, and such a hinge is shown in the drawings. In the normal closed position of the sash the same rests with its lower rail o on a horizontal stool (o on the sill, the outer sides of its stiles L2 If bear against vertical stops or strips a a2, secured to the inner sides of the frame side jambs, and the outer side of its top rail b" bears against a horizontal stop or strip af", secured to the under side of the frame-head AC The side strips a may be adjusted to the sash by screws passing through horizontal slots L5 in said strips and entering' the side jambs, as shown in Figs. 2, 3, and 5.

C represents a faceplate, preferably of metal, which is secured lengthwise to the upper side of the stool, and D is a similar faceplate secured lengthwise to the under side of the bottom rail of the sash. These plates are provided with cooperating shoulders which are adapted to interlock in the closed and lowered position of the sash for preventing the sash from swinging on its hinges. These shoulders are preferably formed by means of a longitudinal locking-rib c, arranged on the upper side of the stool face-plate, and a corresponding groove d, formed in the opposing sash face-plate.

E represents a lifting-lever whereby the sash is raised for disengaging its bottoni groove from the locking-rib on the stool and permitting the sash to be turned. This lever is arranged in a recess e in the stool underneath its face-plate and is pivoted to the under side of the latter, so as to turn in a vertical plane at right angles to the plane of the sash. The rear arm e' of the lifting-lever projects upwardly through an opening c2 in the stool face-plate and into engagement with the under side of the sash face-plate D when the sash is closed, while its front arm e projects laterally from the inner side of the stool, as shown in Fig. 2. The lifting-lever may be pivotally supported in any suitable manner, preferably by means of two cylindrical knuckles @4, arranged on its opposite sides and engaging with corresponding sockets e in the under side of the stool face-plate, and a coupling-bolt e, connecting the st ool face-plate and the lifting-lever in line with the axis of its knuckles, as shown in Figs. 2, 3, and 7. The front arm of the lifting-lever is provided with an opening F, extending vertically through the same, a locking-shoulder f, arranged underneath the inner edge of said opening', and a guideway or face f', extending' lengthwise from the front end of the lever to the front edge of the opening therein.

G'represents a catch whereby the sash is locked in its lowered and closed position. This catch is pivotally mounted on the lower portion of the sash above the lifting-lever, so as to turn in a vertical plane, and is provided with a downwardly and rearwardly projecting hook g, which is adapted to interlock with the shoulder f of the lifting-lever, and also with an upwardly-projecting arm or toe-piece g', whereby the catch may be turned for disengaging its hook from the shoulder of the lifting-lever. The preferred means for pivotally connecting the catch with the sash consists of a transverse knuckle g2, arranged on therear side of the catch and seated in a socket g in the upper side of the sash faceplate D, as shown in Figs. 2 and 11. While the hook of the catch is in engagement with the locking-shoulder of the lifting-lever, the front arm of the lifting-lever bears against the under side of the stool face-plate and is rigidly held in this position, thereby preventing the sash from being lifted and disengaging its bottom groove from the locking-rib on the stool face-plate. When it is desired to open the sash, the catch is first turned in the proper direction for disengaging its hook from the lifting-lever, so as to release the latter, and then the lifting-lever is turned in the proper direction for lifting' the sash and disengaging its locking-groove from the lockingrib of the stool. The sash may now be swung inwardly on its hinges by taking hold of the knob or handle b5 on the free end thereof. This unlocking device is located near the iioor and can be conveniently operated by lirst moving the foot laterally against the toepiece of the catch, thereby moving its hook forwardly out of engagement from the lifting-lever, and then pressing the foot downwardly on the front arm of the lifting-lever, thereby raising the rear arm thereofl and the sash resting thereon. Upon swinging the sash open after the same has been unlocked the catch is withdrawn from the opening of the lifting-lever. Upon swingingthe sash shut the hook of its catch during the last part of this movement engages with the guidewayf' of the lifting-lever and is directed by the same into the opening thereof. After the sash has been swung shut it drops and depresses the rear arm of the lifting-lever and elevates the front arm of the same. During this movement of the lever the rear edge of its locking-opening defiects the hook of the catch, and after this edge has passed above the hook the latter is automatically turned by its weight into engagement with the locking-shoulder of thev lifting-lever, thereby automatically locking the sash in its depressed position.

H represents a stationary guide or supporting-arm whereby the sash is held in an elevated position while turned open. The upper side or bearing face of this guide is flush with the upper side of the locking-rib of the stool face-plate and extends forwardly from said rib at a point between the sash, hinges, and the locking device. The supporting-arm is preferably curved concentric with the hinges, as shown in Figs. 5, 6, and 7. Upon turning the sash open after being raised the sash rests with its lower face-plate on the supportingarm, thereby preventing the sash from dropping to its lowermost position when the same is swung away from the face-plate of the stool and clears the same, as shown in Fig. 3. Upon swinging the sash shut it rides in its elevated position on the supporting-arm until it is closed and its locking-groove is in alinement with the locking-rib of the stool. When the sash reaches its closed position, it clears the supporting-arm and drops by gravity into its lowermost position, thereby engaging its locking-groove with the locking-rib and also operating the automatic lock, whereby the sash is held against rising and turning.

For convenience in manufacturing and applying the stool `and sash face-plates each of these plates is made in two sections. The sections c al of these plates, applied to the stool and sash farthest from the hinges, are varied in length, according to the width of the sash; but the face-plate sections c2 (Z2 next to the hinges, which carry the sash locking, elevating, and supporting mechanism, are always of the same length and applicable to sashes of different widths. By thus making the faceplates in sections the cost of equipping' windows of different widths with this fixture is reduced, because the lock-carrying sections can always be cast from the same pattern, while the plain sections can be stamped out of sheet metal and cut into the required lengths to suit diii'erent widths of Windows.

In order to lock the upper part of the sash and prevent the same from becoming warped,

'IOO

a locking and retaining device is provided, which is constructed as follows: I represents a locking-plate arranged lengthwise between the top of the sash and the under side of the upper jamb of the frame. This plate is pivoted at its rear longitudinal edge to the under side of the upper jamb, preferably by screws z', so that the plate can turn in a vertical direction. The front edge of this plate is provided with a depending longitudinal flange e", which in the normal closed position of the sash engages against the front side of the same, as shown in Fig. 2. Upon raising the sash its upper edge bears against the under side of the locking-plate between its pivot and its lockingflange, whereby said plate is caused to swing upwardly. As the sash rises its upper rail bears against the locking-plate at a point which is nearer its pivot than its locking-ange, which causes the extent of movement at the free edge of the plate to be greater than the extent of the upward movement of the sash. The parts are so constructed that when the sash reaches its uppermost position it deflects the lockingplate upwardly sufficiently to carry its flange above the upper edge of the sash, so as to permit the latter to be swung inwardly from underneath the locking-plate. fhile the sash is thus swung inwardly into an open position clear of the locking-plate it engages against the under side of a supporting-arm J, as shown in Figs. 3 and 12, whereby the locking-plate is held in an elevated position. The supporting-arm J extends forwardly from the locking-flange and has its under side flush with the lower edge of the said flange. This arm is preferably curved concentrically with the sash-hinges and is of such extent that it will always rest ou top of the sash in all positions of the latter. l/Vhen the sash is again closed into alinement with the locking-plate, the latter drops by gravity upon the top of the sash and engages its locking-flange against the front side of the same, thereby locking the upper part of the sash and also holding the same in position so as to prevent warping thereof. As the locking-plate rises under the lifting-action of the sash this plate recedes into a recess j, which is formed in the under side of the upper jamb opposite the free end of the plate, the bottom of this recess being beveled from the pivot of the locking-plate toward the inner side of the frame. For the purpose of producing a compact construction the pivot of the locking-plate l is arranged adjacent to or in line with the outer side of the sash, and in order to permit of this arrangement of the pivot the top of the sash is beveled on its outer corner, as shown at j", Figs. 2 and 4, thereby permitting the sash to be raised freely without cramping the locking-plate or lifting the same' an unnecessary extent. To enable the throw of the lockingplate to be adjusted so as to insure lifting of its flange above the top of the sash preparatory to opening thesame, an adjustable bearing is provided on the upper edge of the sash for engagement with the locking-plate. This adjustable bearing preferably consists of a screw f2, which engages at its lower threaded end in the top of the sash and bears at its upper head end against the under side of the locking-plate, as shown in Fig. 2. Upon turning this bearing-screw so as to raise or lower the same on the sash the extent which the locking-flange overhangs the upper inner corner of the sash may be regulated for taking up wear, shrinkage, or sagging of the window and maintaining the same in working condition.

The top of the sash is preferably covered with a metal face-plate It' for reducing the wear on the same, this plate being shaped to conform to the beveled top ofthe sash, as shown in Figs. 2 and 4.

In order to effectually prevent water and dust from passing through the joints between the sash and frame, weatherproof attachments are provided, which are constructed as follows: .L represents a horizontal deilectorflange arranged lengthwise along the lower outer corner of the sash and projecting laterally beyond the joint between the lower edge of the sash and the stool. This flange is preferably formed in one piece with the face-plate on the lower side of the sash, as shown in Figs. 1, 2, and 10. The under side of this deflector-lange is provided between its outer edge and the joint between the sash and stool with a longitudinal groove l. The water running down the outer side of the sash strikes the flange L and is deflected outward from the joint between the sash and stool and caused to drip upon the sill beyond said joint. Any water which tends to pass around the lower edge of the deflector-lange to the joint between the sash and stool is checked by the groove Z therein, because the water is unable to cross said groove and reach said joint. This grooved flange, together with the interlocking rib and groove between the stool and the sash, forms a double check, which effectually prevents water and dust from passing through this part of the window. The uppersash stop o3 is provided on its inner side, vwhich faces the sash, with a horizontal rabbet m, forming a horizontal inwardly-projecting flange m on the lower inner corner of said stop. The upper outer corner of the sash is provided with a horizontal weather-flange n, which during the closed position of the sash extends over the stop-flange m, as shown in Fig. 2. The cooperating flanges m n form an obstruction which intercepts the incoming dust and water and prevents the same from passing through the joint between the upper end of the sash and the head of the frame. This obstruction, together with the lockingplate Lthus renders the joint between the .top of the sash and the head of the frame IOO IIC

ISO

iro

practically weatherproof. For convenience the weather-fiange 11, is made in one piece with the face-plate on the top of the sash. The joints between the sides or stiles of the sash and the side jambs of the frame are rendered weather tight by means of sheet metal weather-strips O O. rl`he weather-strip O is interposed between the backof the sash-stile f next to the hinge and the adjacent side jamb of the frame, while the other strip, O, is interposed between the sash-stile b2 and the opposing stop a. Each of these strips is of an angular form and consists of a flat attaching-web 02 and a trough or gutter shaped bearing-web of, which opens toward the attaching-web. The back of the stile nearest to the hinges is provided with a vertical slip p, and the opposing face of the adjacent side jamb is provided with a vertical groove p. The weather-strip O is arranged with its flat attaching-web in the slit p of the hinge-stile, and its trough in the closed position of the sash is arranged to engage with the groove p of the strip O. The trough while engaging the groove p opens toward that side of the joint between the sash and the frame which is opposite the hinge, and the edge of the trough is within the groove 79. The weather-strip O is pivoted centrally to its stile by a screw or pin q passing horizontally through the stile and web,'and the free edge of the trough o is preferably curved or rounded, as shown at o4, Fig. By this construction the strip O can rock in a vertical plane and also be deflected upon engaging the groove in the frame for adapting itself to the latter and forming a tight joint between these parts of the sash and frame. Any dust or water which may be driven from the outside into the outer part of the joint between the hinge-stile and the frame is intercepted by the weather-strip O and directed into the trough thereof. This trough is of larger capacity than the joint between the sash and frame, whereby the dust and waterentering the same are conducted downwardly and discharged upon the stool and sill and thence escape outside of the window. By this means the dust and water entering the hinge-joint between the sash and frame is carried away as fast as it enters this joint, thereby preventing' the same from passing through the window. The stop a is provided in its front side or face with a vertical slit 7', and the outer opposing side of the sash-stile b is provided with a vertical groove 7". The weather-strip O' is arranged with its flat attaching-web o2 in the slit fr, and its trough-shaped web 03 is arranged to engage with the groove fr in the opposing sash -stile Z22. The trough of the strip O' is on that side of the fiat web so that upon closing the sash the trough opens toward the outer side of the adjacent stop a, as shown in Fig. 5. The trough of the weather-strip O is preferably of tapering or V-shaped form, and the groove fr, which receives the same, is

of corresponding form. The flat web of the weather-strip O is pivoted centrally to the stop bya screw or pin s, passing through the attaching-web of the strip O and the stop a. The strip O is thus capable of rocking in a vertical plane and adapting itself to the sash for forming a tight joint between the same. Any dust and rain which is driven between the stop a and the stile 722 is intercepted by the weather-strip O and conducted by the trough thereof downwardly to the lower outer part of the window, where it escapes.

kBy the use of these improvements in 'a French-easement window the same may be locked securely and its joints closed tightly, thus overcoming the objections which have heretofore been urged against this kind of window and rendering the same as serviceable as any other style of window.
