[Vveytar dupes R Roy Patented May 27, 1913() illiiil STATE er'r or JAIMES B.. ROY, OF WINNIPEG, MANITOBA, CANADA WINDOW Application filed June 18,

The invention relates to improvements in windows and an object of the invention is to provide a structure which will permit ofthe sashes being simultaneously raised or lowsered and counter balanced in all positions and also of the swinging or" both sashes into the room as and when desired., the sashes being liingedly supported from the frame during such in swinging movement and lo being also arranged so that they can be removed entirely rom the frame after they have been swung into the room.

A further object of the invention is to construct the parts in a simple,.durable and in- 15 expensive manner and so that they can be readily introduced on existing frames and sashes without materially altering either the frame or the sashes and further such that when the parts have been introduced they 2O are not unsightly.

A more specific object of the invention is to associate racks with the sashes and pinions with the frame and engaging the racks and causing the simultaneous movement of the sashes when raised or lowered and of the counter balancing of the sashes in their various adjusted positions.

A further speciic object of the invention is to provide the frame and the sashes with members which are adapted to become engaged when the sashes are both brought to a position centrally of the frame and when engaged to provide pivots for supporting the sashes and accommodating their movement during the interval they are being swung into the room.

A further specific object is to provide the frame at the side opposite to the pivot members with removable hatten and parting strip sections which permit of the sashes being swung inwardly whilst carried by the pivot members aforesaid. y

`With the above more important and other minorobjects in view, which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described7 reference being had to the accompanying drawings, in which 1928.

Fig. 18 is a view corresponding to Figure 17 but with the parts shown in the position l they occupy when the sashes are swung inwardly towards the room. l

In the drawing like characters of reference indicate corresponding parts in the several i'igures.

The window frame l is ofthe conventional type and presents'the inner and outer battens 2 and 3 and the intervening parting IGH strip 4 which provide vertical inner and outer guide channels 5 and 6 for the lower (inner) and upper (outer) sashes 7 and 8.

The outer battens 3 pass from the top to the bottom of the frame as does also the inner hatten and the parting strip at the left hand side of the frame. The inner hatten at the right hand side of t-he frame is provided centrally of' the frame with a removable batten section 2 of a length slightly greater than the length of either sash. The section 2 when removed permits of the inswinging into the room of the lower sash in a manner later described.

Any suitable means can be provided for detachably fastening the batten sections 2. I have herein shown the lower end of the stationary batten provided with a locking plate 9 slidably attached thereto and having the upper end provided with a linger piece 9 and the lower end longitudinally slotted to provide three lingers 92, the central finger of which is offset laterally in respect to the other two. The locking plate is adapted to engage with a similar stationary plate 10 permanently fastened to the underlying stationary portion of the batten, the plate 10 having fingers 10 adapted upon engagement with the lingers of the sliding plate to lock the hatten against removal. rlhe upper end oi the batten is supplied with a stationary plate 11 of the same form as the plate 10 and the fingers 11 thereof are adapted to pass into locking engagement with lingers 12 carried by an overlying complementary stationary plate 13 permanently fastened to the overlying lower end of -the upper stationary portion of the batten. Obviously one can release the hatten by raising the finger piece 9 to cause the lower mating fingers to pass out of engagement and then by pullingout the freed lower end of the batten7 can withdraw the fingers 11' from those 12.

The parting strip 4 at the right hand side oi' the frame is also provided with a. removable section 4 located centrally of the frame and also adapted when removed to permit of the inswinging into the room of the uppersash. Theremovable parting strip section can be held in place in any suitable manner and is herein shown as provided at the ends with sliding locking plates 15 equipped with finger pieces 15, the sliding plates being adapted to engage behind stationary plates 15X secured to the stationary parts of the parting strip. The ends of theremovable parting strip section are positively prevented from lateral displacement by fins 16 passing slidably through slots provided in the section and entering receiving slots formed in the window frame (see Figure 8).

The removable section of the parting strip is provided centrally of its length with a pinion 17 which has a diameter somewhat greater than the width of the parting strip so that the pinion protrudes into the adjacent channels 5 and 6. According to the present construction7 i have divided the removable section of the parting strip and reunited the parts thereof by a special casting 18 which is fastened by screws 18 to the parting strip section parts and is provided centrally with a cross slot which receivesv the pinion, the pinion being rotatably mounted on ay screw 18X passing centrally across the slot. rlhe casting is supplied with legsy 18" which are adapted to enter receiving Ypockets formed in the face of the window frame and preventing lateral springing oi the central portion of the removable parting strip section.

rlhe sashes are both provided with similar rack bars 19 and 19 of the form best shown in Figure 4.

rlhc rack bars extend longitudinally of the sashes and are counter sunk in one of the edges thereof and fastenedtliereto by screws passing through suitably positioned lugs 19X provided on the bars. The teeth of the racl: bars are continuously in mesh withV the opposite sides of the pinion in the manner best shown in Figure 2 and according to this arrangement., it will be obvious that the sashes counter balance one another through the pinion and that upon the lower sash being raised, the upper sash will move down an equal amount and vice versa. The pinion is located centrally of the length of the frame and accordingiy when 'thesashes are brought to a position centrally of the frame, that is, one directly behind the other, the right hand sides of the sashes can be swung inwardly of the room provided removable batter. section and removable parting strip section be taken out.

In order that there may be no binding action occasioned when the sashes are sliding in the frame7 l have provided the left hand sides of the sashes with rack bars identical to those at their right hand sides and the left hand parting stri y 'h a pinion engaging such racl s such structure is merely the duplication of that previously lescribed, a further description is not given.

Means are provided for pivotally supporting the sashes at he left hand side of the frame and at the time they are to be swung inwardly into the rooin and such are designed to in no way interfere with the vertical sliding movement of the sashes in the window frame. f i V To the left hand side of the iran e, l cure a pair of sin ilar hinge wings 29 ai 20, these being spaced a predetermined oirtance apart and having the bases thereof counter sunk in the frame and partially underlying the inner batteri 2 that side of the frame. Each hinge wing is provider with an arm 20X positioned right angles to the 'face of the Jsaine and located to the iii;

side of the channel 5 and each arm carries a downwardly extending hinge pin 2l, the lower end ot which is pointed.V

To the left hand side of the lower sash is fastened a pair of spaced hinge wings 22 and 22 and these are both provided with entending vertically aligned sleeve like bearings 23 and 23 which are aoapted in the up sliding movement ot the lowerI sash in the 'l'rame to receive the pivot pins 21, such occurring when the inner sash has been brought' to a position where it can be swung into the room upon the removal ot the inner hatten section 2.

In order to prevent the dropping oi" the sash as is being' swung into the room, l have provided the lower wing 22 with a spring pressed locking latch 24 which in the raising movement of the inner sash is adapted to slide over the pin and arm of the wing and then become caught over the upper side of the said arm. ln other words, when the inner sash has been brought to the position where it is to be swung into the room, the bearing sleeve 23 is on the pin of the lower wing 2 and the latch 24 is overlying the arm of the wing. Consequentl the sash cannot 'fall wien it is swung' inwardly of the room as it is supported by the latch and swivels on the pins 2la The latch is herein shown projecting Ytrom a casing 25 carried by tl e wing and as provided with an arm 2e connected by a pin 2e? carried by the upper forked end of zJ lever 26. llhe lever is pivotally mounted on a cross pin 26 carried by the casing and has the lower end thereof also torlred. spring 2? engages the casing and the lever and normally presses the lever in a direction which holds the latch normally in the position best shown in Figures ll and l2 ot' the drawings, The casing carries also an eX- tending pivoter `linger piece 28 which has an extending finger 29 engageable with the cross web 252 ci the lever.

The arrangement is such that when the tinger piece is down pressed, the latch is drawn into the casing and canv be cleared from the upper end of the arm 20X ot the wing 20', ccording to this arrangement, one can remove the lower sash it he so desires after it has been swung into the room and further one can release the sash for ve "cal sliding movement within the frame after it has been hangers are identically constructed, a description ot one will sufice. n

Each hinge embodies a central wing 30 and two side wings 31 and 32, the several wings being pivotally connected in the Well known manner by pivot pins 33`an d 34. The wing 3l is permanently 'fastened by screws 3l to the outer tace ot the upper sash and has one edge thereof turned outwardly to provide a hook 35 and the other edge thereof turned inwardly as indicated at 36 and carrying eyes 37 for the hinge pin 33 which pin is located centrally of the width of the sash. The central wing 30 is substantially T-shaped in hori- Zontal cross section and carries two sets of eyes 38 and 39, those 33 being complementaryto the eyes 37 and receiving the pin 33. The wing 32 is provided at one edge with aligned spaced eyes l0 adapted to pass between the eyes 39 and to receive the hinge pin 34 and at therother edge with a single comparatively large eye 4l positioned at the upper end of said wing.

When the upper sash is in its vertical sliding position within the trame, the wings of the latter hinges arel folded together in the manner best shown in Figures 14 and la7, the wings 30 at suoli time moving up and down wit the sash within the channel 6 andhere it will be observed that the wing 3l is provided with an offset 4t2 to receive, in the folded position ot the wines, the transverse head like portion 30 ot' the wing 30 and that the eye 4l is caught in the hooks 3510i? the wing 3l and is accordingly prevented from swinging around the pivot pin 34.

The hangers i3 and dil carried by the traine and which receive the eyes el of the doubly hinged wing are as before stated identically constructed and they are positioned on the trame such that whenv the upper sash has been brought to the position where it is swung inwardly into the room the hinges thereof will be received by the hangers. Each hanger embodies a substantially rectangular plate counter sunk in the base of the channel 6 and fastened thereto by screws e5 and the plate is provided the outer edge with a substantially Z-shaped extension l5 which tits around the adjacent edge ot the hatten 3 and carries a ilange 47 disposed at right angles to the face of the hatten and terminating in a relatively large lower eye i8 complementary to the eye 4l; The eye 48 receives a hinge pin i9 which is permanently fastened thereto and which is adapted to enter the eye il to at- I tach the sash hingedly to the trame. rlhe upper end of the hinge pin is pointed so that it will readily pass into the eye ll when the upper sash is moved down within the trame.

The upper end oi each eye 48 is provided with a stop shoulder 50 and above this with an upwardly spiralling face 5l and the eye il has the lower end provided witha spiralling tace 52 complementary to that 51 and iso with a shoulder 53 engageable with the shoulder and the arrangement is such that when the upper sash is being swung into the room, the eye 41 will be caused to move upwardly on the pivot pin 49 due to contacting spiralling faces 51 and 52 and the shoulders 50 and 53 will come in contact and prevent the outward buckling of the joint at the pin 43.

To make this latter clear, I refer to Figure 18 and it will be observed that unless prevented, it would be possible for the wing 32 to swing in the direction indicated by the applied arrow which would make it difficult to replace in the frame the inswung sash. The shoulders 50 and 53 are designed to come in contact and prevent the swinging of the wing 32 further than a predetermined distance in the direction of the applied arrow Figure 18. As aforesaid, whenthe upper sash has been swung into the room, it has'been raised slightly due to the inclination of the engaged faces 5l and 52 and accordingly when one is desirous of replacing the upper sash in the frame, the eyes 41 have a natural tendency to gravitate downwardly and rotate in a c irection opposed to the direction of the arrow Figure -18 which causes the said wings 32 to initially fold in towards their original positions asshown in. Figure 17; Subsequently the upper sash is swung into the frame turning on the pivots 34 and 33, the hinged parts finally taking the position shown in Figure 17.

lt is here pointed out that the iiange'f47 is provided on the inner side with a lengthwise extending channel 54 (see Figures 17' and 18) and this channel provides a clearance space for the eyes 39 and 40 to swing vinto when the upper sash is being initially swung into the room and that the inner ends of the rack teeth of the inner sash as well as the inner corner of the inner sash are slightly beveled oli-to allow them to escape the parting strip when the said lower sash is being replaced in the frame.

The above completes the description of the parts and in order that the invention may be better understood, I will now describe the manner in which it is used. lNhen one wishes to ventilate a room, he raises the lower sash and this causes through the racks and pinions, the down movement of the upper sash an equal amount and as the sashes are approximately of equal weight, they counter balance one another through the pinions. lf it is desired to open or swing the inner sash into the room, it is only necessary to raise the lower sash to a central position within the frame, then take out the removable batten section 2 and subsequently swing the said sash into the room at which ti -e the sash is turning on the pins 21 and is prevented from falling by the latch 24. If it is desired to entirely remove the sash from the window, one has simply to depress the finger piece 28 to release the latch and this allows the eyes 23 23 to lslide downwardly o the pins 21;

If it is desired to swing the upper sash into the room', the inner sash is swung into the room in the manner just describedv and having done this, one then removes the parting strip section 4 and swings the upper sash into the room, the hinges thereof permitting such movement and taking the final position as shown in Figure 18.

One can then remove both sashes from the frame' if they so desire by releasing the latch 24 of the inner sash and by lifting the upper sash clear of the pivot pins 49.v To reset the removed sashes back into the frame, it is only necessary to reverse the above operations and the hinges provided accommodate the movement, those for the upper sash folding back into the position shown in Figure 17.

JV hat l claim as my invention is l. kThe combination with a window frame, of vertically extending battens and parting strips secured to the sides of the frame and forming vertical guideways and having centrally located removable sections at one side of the frame, upper and lower sashes slidably mounted. in the guideways, rack bars secured to the sashes and located in pairs at opposite sides of the parting strips, pinions rotatably carried by the parting strips and engageable with the pairs of rack bars afore said, said pinions being located centrally of the frame and one of said pinions being removable with the removable parting strip section and said removed parting strip and batten sections permitting of the inswinging of the sashes upon the sashes being brought to a central position in respect to the frame and engaging hinge sections carried by the frame and the sashes, said hinge sections becoming engaged when the sashes are brought to a central position within the frame and being adapted to support the sashes when swung inwardly as aforesaid.,

2. The combination with a window frame, of vertical vbattens and parting strips carried by the frame and forming vertical guides, the parting strip and the inner batten at one side of the frame having removable centrally located sections, upper and lower sashes slidably mounted in the frame and inwardly s vingable upon the latter batten and parting strip sections being removed, pairs of opposing rack bars permanently secured to the edges of the sashes, pinions located centrally of the sides ofthe frame and carried by the parting strips and continuously engaging the adjacent rack bars ofthe sashes,.hinge forming members carried by the frame and the inner sash, said members being adapted to come into engagement upon the inner sash being raised to a central position within the frame, means releasably locking the hinge members engaged and hinge forming sections carried by the upper sash and the frame and adapted to come into engagement and support the upper sash when the same is brought to a central position in respect to the frame, all the said engaged hinged members being adapted to support the sashes upon the removable batten and parting strip sections being removed and the sashes swung inwardly of the room.
