VApplication filed .Tune 9, w13, Serial No. 302,655. Renewed November l, 1920. Serial No. 421,156.

To @ZZ 'e0/tom t may-concern `Be it known that l, Jnssnl FnnsoNs, a citizen'of the United States, and resident of the city of Seattle, county of King, State of lVashington, have invented certain new and useful lmprove-ments in lvindow-Operating .Means, of vwhich the following is a specificati-on.

:My invention relates to windows `and the manner` of securing, guiding and controlling the sashes in 'their movements of lopening' `and closing, and the means employed for :looking said sashes in adjusted position.

The object of my invention is to provide ameans for mounting window sashes in window'frames so as to secure certain novel and desirable results, and to better secure results which have been before secured by other means.

One feature of my invention is the employment of means for better holding and guiding the sash in the window frame, in which a guide strip is carried by the sash, and the frame is provided with a channel in which said strip travels, and means whereby said strip may be retracted into the stile of the sash when it is desired, and thus facilitate the removal of the sash from the window frame.

Another feature of my invention is the employment of means whereby the window sash is supported and raised by the action of a spring and mechanism whereby the sash may be locked in adjusted position and released at will.

A further object of my invention is to provide a guide member which enters the groove or channel in the window frame 'and about which the sash mayy turn as a pivot, so that when the guiding strip is retracted within the channel ofthe sash, said sash may be turned down so as to expose the outer surface of the glass for convenient cleaning by a person within the room.

'Other objects of my invention may be determined by an inspection and study of the claims herein.

In the accompanying drawings l have shown my invention embodied in the forms of construction which l now prefer to use.

kFigure l is a side view of a window having my improved type of construction incorporated therein, portions of both the window frame and the window sashes being shown broken away and ill Section in order to better illustrate the construction and operation of parts.

Figure 2 is a section taken upon the line 2-2 Aand'Z-QO of Figure l. The section of the lower sash is taken upon 'the line 2-20, while that of the 'upper sash is taken upon the line 2 2. f

Figure 3 is a vertical section taken approximately upon the center line vof the Sash and the window frame.

Figure i is a horizontalsection taken -upon the line 4 -4 of Figure l.

Figure 5 is a View ofthe inner or back face of the window frame at the point where the sash raising and locking means are installed.

Figure 6 is a vertical transverse section taken through a window casing showing the sash lowered and swung inward for cleaning.

Figure 7 shows, in perspective, one edge 'of a window sash having my device mounted thereon.

Figure 8 is a perspective of the lower corner fragment of a sash showing the relative position of the rack bar when retracted into the channel in the sash.

Vln carrying out my invention l provide a metallic frame vor casing which is designed to be secured to the outer edges of the Stiles of the sash, which casing has incorporated therein the guiding strip, and means for projecting and retracting the same.

The window casing employed in connection with my invention has a flush outer surface in which is formed two vertical grooves for the reception of the guide strips of respectively the upper and lower sash. In other words, instead of forming guide channels by securing stops or parting strips to the face of the window Lframe, the sash is provided with guide strips whichproject from the facethereof and-which enter channels recessed in the face of the window cas ing. In Figure 2 the 'relative position of these parts is shown.

The window frame l is provided with channels or grooves, l0, into which project thestrips 2 which are supported by the w1n dow sash. The sashes 3 are provided on the outer-edges ofV their stiles with grooves 30, and a metallic casing 4; is secured upon each vertical edge of the sash.

This condition of the parts is shown in Figure 8 and 'also in Figure 3. This facing ormetallic casing 4 has outer wings 41 which Y fit closely against the side faces of the stile 3. It Vmay be secured thereto at intervals, as

' by means of screws 42, so that by adjustment Vgreatest expansion or contraction across the grain, rather than lengthwise, hence the lit of the sash in its frame is controlled almost entirely by the expansion or contraction of its stiles. When the metal casing is permanently secured, by means of the screws 42 or other securing means placed adjacent the inner edge of the stile, expansion or contraction of the wooden` stile 3 within the metal casing 4 will -not affect the overall width of the window sash. The screws 42 or other securing means being placed as near the inner edge of the stile as is practicable, the position of the outer guiding surface of the metal casing 4 is little affected by variations in the width of the stile.

The bar 2 is provided with teeth 20, thus making of it a rack bar. Means are provided whereby this' rack bar may be retracted into the channel 40, or projected so as to enter the channel 10 in the window frame, in which latter position it acts as a guide for the window sash to secure proper movement thereof and to prevent removal of the sash. Various means may be provided for shifting this bar so as to project and retract it. The means which I prefer to use and whichhave herein been illustrated are as follows.

The .bar 5 extends lengthwise of and bears against the inner edge of the bar 2. These two bars are held in engagement so that there maybe a limited longitudinal movement between the two, as by means of clips 21 carriedby the bar 2, which clips extend about lthe bar 5. The bar 5 is connected with the controlling means by having a crank arm 60 which is secured to a short shaft 6, and which isvconnected with the bar 5, yas by means of an arm 5,0.

y The' shaft 6 preferably projects from the inner face of the sash and is provided with a button 61 or other means by which it may be readily, turned. It is evident that by turning this button and its attached parts, the bar 5 and the rack bar 2 which is secured thereto may be forced outward or withdrawn as desired. When withdrawn to the position shown yin Figures 3 and 8 the rack bar 2 no longer forms a retaining means for the window sash and the sash may be removed from the window frame, :excepting as it maybe held by other means. j f

At one end of the sash, preferably the .sash so as to lower end, is mounted a .guide block 7 )This surface of the window glass accessible fromq block lits the channel 10 in the window frame within the room for cleaning. If it b e de- Y sired to remove the window `sash entirely from the casing, this may then be done by lifting one end of the sash until the block 7 is clear from the channel 10. Y

It is desirable that the rack bar 2 may be securely held in its projected position so that there is no tendency to vaccidentally recede into the channel in the sash. To secure this I have providedV the bar 5, Vupon which the bar 2 is carried, with short legs 51, which, when the bar is in retracted position, enter holes 43 in the inner part of the channel 40. These legs are of such length that when the rack bars 2 are projected, as is shown in Figure l, they engage withthe outer face of the bottom web of the channel 40 and thus prevent any forcing of the bar inward.

Each stile of the sash is provided with the mechanism which has just been described. At each side of the window Vframe and sash means are provided for raising and locking the sash. Such means employ a gear wheel, as 8, which is journaled in position such that when the bar 2 is projected, it will mesh with the teeth of this gear.

In connection with the gear 8 is provided a spring which acts upon this gear in Vsuch manner as to tend to raise the sash. The strength of the spring should be so proportioned that it will be able to lift the sash to its uppermost position. The springs 71 employed are of the kind which is used for clock springs, being fla-t, spirally wound strips. Secured to the shaft of each of these springs are a ratchet wheel 8l and a gear wheel 80.'

The latter wheel meshes with the wheel 8. The object of mounting the spring upon an axis removed from that of the wheel 8, is to get the saine farther away from the window permit the using of a spring of ample size. Y v

It is evident that if this spring is of proper strengthit will be able to raise the window sash whenever it is released so as to permit such movement. Normally al locking dog prevents such action. In connection with the lower sash -a single locking dog will be sufficient. This dog will act to prevent raisingof the window sash, but would not Aprevent lowering thereof. SuchV a dog82 is shown in Figure 1. In order to release this, a lever, as 83, is pivotally mountedon the inner face of the window frame with one end in position to engage the dog 82 so as to release it. To the other end of the lever is secured a plunger 84, which extends to the outer face ot the frame and is adapted to be engaged by, and, by pressing inward thereon, to release. the dog 82.

In connection with the upper sash two loclringdogs are provided, whereby the sash may be held in adjusted position aga-inst movement either up or down. This requires the use of two ratchet wheels 81 and the compani'on dogs 82. The releasing mechanism, however, need not be duplicated. The ends of the dogs 82 are brouglt together in position to be engaged at the same time by the single releasing lever 83.

By reason of the fact that the rack mechanisms abo-ve described are contained within a casing-4, which is secured upon the outer edges of: thel stiles of the sash, it is possible to fit these a little farther out or in when installing the window, thus securing a tight lit of the window sash in the window frame, when otherwise there would be a loose tit. Because of thev manner in which the casing 4 is supported and of its nullifying the effect of expansion and contraction of the stiles 3, the teeth of the gear 8, which are quite small, will always mesh with the teethY or the rack bar 2. Vithout provision ,of some such means the casingy 4 would have to be adjusted in or out continually to keep these tee-th inmesh, for otherwise shrinkage of the stile 3 would withdraw the rack bar from mesh.

The strip 2 which forms the rack bar should be made of metal and the facing 4 for the edges'of the sash should also be made of metal. This being so, it is possible to obtain a snug tit which will prevent wind from blowing through without securing any binding action. These parts being also made of metal are not liable to warp, as would be the case were they made of wood.

The roller 25 which is journaled in the upper end of the guide bar 2 is designed to bear upon the bottom of the groove in the window frame when the bar 2 is projected. This prevents the possibility of this end of the bar scraping and wearing the bottom of the groove by reason of the sash moving up and down.

A window sash equipped with this sort of apparatus may be opened as much as desired and automatically locked in this position. If a sash be equipped with the double locking mechanism such as has been described as applied to the upper sash, this sash could not be moved up or down, without releaing the same by the action of one of the buttons 84. If, however, this is not desired, a single locking means in connection with a spring 7l which is not sufficiently powerful to raise the window, may be employed. This will serve to prevent opening ot the sash further than is desired and will permit closing without releasing` the locking mechanisms, as has been described in connection with the lower sash. lVhether a single or double locking mechanism is employed is immaterial.

I do not deem it necessary to provide the locking mechanism described except at one side ot the window. At the other side of the window the window sash supporting and releasing` mechanism may be left free to act at all times. It is, however, desirable to provide means for locking the spring against running down whenever the rack bar is retracted into the channel in the sash. Such a device is shown at the left hand side of the Figure l. The locking dog 9 is adapted to engage a ratchet wheel, as 8l, which wheel operates in the same manner as the gear wheel of the mechanism previously described. This dog, however, has on one end a. roller 90 which engages with the outer face of the rack bar. These parts are so adjusted that when the rack bar is in itsv outermost position the engagement thereof with the roller 90 releases the lockingdog 9 and when the rack bar is retracted, the roller- 90 carried by the dog 9, swings outward and thus engages the locking end of the dog with the ratchet wheel Sl. Therefore, the act of retract-ingthe rack bars 2 serves to automatically apply the lock to the sash raising mechanism at this. side of the window.
