SNOBECK WINDOW STRUCTURE Filed July 20, 1955 United States This invention relates to improvements in window structures and more particularly relates to window structures in which the window sash may slide along its guideways to open and close the window and may swing inwardly for cleaning from the inside and for ventilation purposes.

An object of my invention is to provide a novel and improved draft-free window structure mounting the win dow sash to be pivoted to an open position for ventilation purposes and to afford a means for washing the window from the inside.

Another object of my invention is to provide an improved structure and arrangement for guiding a sliding window sash for movement along a window frame, wherein the window sash may be detachably locked from sliding movement along the window frame and may be pivoted about the locking means therefor, to provide a means for pivoting the window for ventilation purposes and for washing the window from the inside.

A further obiect of my invention is to provide a win dow sash and frame therefor, wherein the guideways for the window sashes are in the form of recessed slideways extending vertically along the jamb of the frame, and wherein the slideways are engaged by guide rails recessed, within the sash and extensible therefrom into engagement with the slideways to afford a draft free structure accommodating the window to be readily raised and lowered.

Still another object of my invention is to provide a simple and efficient form of window structure having parallel spaced guideways extending along the jambs of the window frame and opening toward the sash, with slide rails recessed within the opposite rails of the sash for extension within the guideways, wherein the sash is provided with locking bolts released by the slide rails upon extension thereof from the sash, and engage'able with cooperating sockets in the guideways upon retraction of the slide rails within the sash, soas to afford a means for locking the sash from vertical sliding movement and a pivot support means for the sash, accommodating the sash-to be pivoted from the inside for ventilation purposes andfor washing from within.

These and other objects of my invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings where- Figure l is a transverse sectional view taken through a window structure constructed in accordance with my invention, and showing the window sashes in outwardly extended pivoted positions by broken lines;

Figure 6 is a view of the upper window sash, with parts thereof broken away and certain other parts shown in vertical section in order to illustrate the release for the slide rail for the upper window sash; and

Figure 7 is a sectional view taken substantially along line VIIVII of Figure 6.

In Figures 1 and 2 of the drawings, a windowframe structure is shown, which may comprise a lower sill 10, a top head rail 11, and parallel spaced

jambs

12, 12 having guideways 13 and 14 extending vertically therealong.

The guideway 13 may have the usual blind stop 15 extending along the outer side of the window frame inwardly from the jarnb thereof, and may be stepped to be slidably engaged by a stepped side rail 16 of an upper window sash 17. The guideway 14 for a lower window sash 19 may have a shoulder 20 formed therein, along which the outer side of a side rail 21 for the lower sash may slide. The guideway 13 may also be stepped, to be slidahly engaged by an outwardly stepped portion 23 of the side rail of the lower sash 19.

It should here be understood that the shoulder 29 takes the place of the usual parting strip to avoid interfering with inward swinging movement of the upper sash 17.

Along the lower part of each guideway 14 and recessed within the ,amb 12 is a channel slideway 24, extending therealong for the full length of the guideway 14 and adapted to be slidably engaged by a retractible slide rail 25, extensible from a channel-like housing 27, recessed within and extending vertically along each vertical side rail 21 of the lower sash 19.

It should here be understood that both side rails of the sash 19 have a similar channel-like housing 27 within which may be retracted a slide rail 25, and that since the construction on both sides of the window is the same, one side of the window only,.need herein be shown and described in detail.

The channel slideway 24 is shown as having a plurality of sockets 2?, 29 recessed therein to be engaged by a bolt 30, slidably mounted in the side rail 21 of the window sash, to lock the sash from vertical movement along the

guideways

14, 14 and accommodate the sash to be pivoted inwardly about the axes of the bolts 30, 36.

Each bolt 30 is shown as being slidably mounted within a socket 31 extending inwardly from the base of the channel-like housing 27, and in an outwardly spaced cover plate 33 for the upper portion of said channel-like housing. The bolt 3b is likewise shown as extending through a release arm 34 secured thereto as by a pin 35. The release arm 3:4 is shown as depending from the bolt 30 into position to be engaged by an inturned upper end 39 of the slide rail 25 to retract the bolt 30 from the socket 29 as said slide rail is extended into engagement with the slideway 24, as will hereinafter be more fully described as this specification proceeds.

A spring 36 is shown as being interposed between the inner wall of the channel-like housing 27 and the inner side of the arm 34 to bias the bolt 30 in an extended position relative to the side rail 21 of the sash 19 to engage the socket 29.

Each slide rail 25 is shown in Figures 3 and 5 as being mounted in the channel-like housing 27 for extensible movement therefrom on

parallel links

40, 4%. As shown in Figure 5 the slide rail 25 is of a channel-like form, opening toward the base of the housing 27 and having the links 4%, dii'extending within the open portion thereof and pivotally secured thereto as by pivot pins 43, 43. The inner ends of the links 40, 4'0 are shown as being pivoted to the base of the housing 27 on pivot pins 45, 45, ex-

a'rossco tending through the outwardly extending vertical legs of angle brackets 46, 46. Said angle brackets are secured to the base of the housing 27, as by rivets 47.

The housing 2.7 is shown as having parallel inwardly extending guide portions 49, 49 spaced inwardly from the outer walls thereof and slidably extending along opposite sides of the slide rail into sliding engagement therewith, to seal the sash to the window jarnb.

A tension spring 59 is shown as being provided, to bias the slide rail 25 into an extended position from the chan nel-like housing 27. As herein shown, the spring 50 is secured at one of its ends to an ear 51 extending outwardly from the base of the channel-like housing 27 and at its opposite end to an ear 53 extending inwardly from the rail 25.

The lower end of the rail 25 is shown as extending angularly inwardly toward the base of the housing 27, and as being guided in an arcuate slot 55 formed in a face plate 56, which may be secured to the outside of the side rail of the sash. As herein shown a pin 57 is connected with the lower end of the slide rail 25, and extends outwardly through the arcuate slot 55, and has a key 59 on its outer end. The key 59 is of a convenient size and is in position to be grasped by the hand, to retract the slide rail 25 within the channeldike housing 27 upon downward pressing movement on said key. Downward pressing movement on the key 59 will release the upper inturned end portion 39 of the slide rail 25 from the arm 34 and in turn release the bolt 3% to engage the desired socket 2 9, to lock the sash from vertical movement and to form a horizontal pivot therefor. The pin 57 may be threaded on the slide rail 25, as shown in Figure 4 and the key 59 may be turned to tighten said key against the face plate 56 and hold the slide rail 25 in a retracted position.

The upper sash 3.7 is shown as having a channellike housing 6% recessed within and extending along each side rail thereof. The channel-like housing at is like the housing 27 except that it opens from the bottom of the sash to afford a means for retractibly moving a slide rail (it within said housing to release a bolt 63 to engage a sec t in a channel slideway 65 for the upper sash. .ueway 65 extends vertically along the guideway 13 for the entire length thereof.

The slide rail 61 is like the slide rail 2;; and is pivotally mounted for retractible movement within the housing 69 on parallel links 66, as horizontally pivoted to the base of housing on

angle brackets

67, 67. A tension spring 69 is also provided to extend the slide rail 61 from the housing at within its cooperating channel slide 65.

The slide rail 61 has an inwardly inclined lower end portion 75) to which is pivoted a depending link 71 on a pivot pin 72. The link 7% is shown as extending through a slot 75 in a lower intermediate wall portion 76 of the housing 6t) and as being retained between vertically spaced ears 73 74 extending inwardly from the base of the housing 6G, when the slide rail '71 is in a retracted position. A ring 77 is shown as being connected to the lower end of the link 7t"? and depending therefrom. The ring 77' ailords a means to be grasped by the finger to retract the slide rail 61 from the slide 65 into the housing 63, and release the bolt 63, to engage a socket 64. The ring 77 may also hold the rail 61 in a retracted position when abutting the bottom of the ear 7 4.

It should further be noted that the

rails

25 and 61 are biased into engagement with the

respective channel slideways

23 and 65 with sufiicient frictional resistance to hold the window in position during raising or lowering thereof, but still enable the window to be easily raised and lowered.

It may be seen with reference to Figure 1 that when it is desired to swing the

sashes

17 and 19 outwardly, that the lower sash 19 is moved to the upwardly extended position shown by broken lines, to accommodate the bolts 30 in each side rail of the sash to engage the

upper sockets

29, 29. The upper sash is likewise moved downwardly along its guideway to accommodate the bolts 65, to engage tr e lowermost sockets 64, 64-. When the sashes are in these positions the slide rail 25 is released from the pin 33 by depressing the key 57 downwardly along the slot 55 to accommodate the bolt 30 to enter the socket 29.

The fingers are also inserted within the

rings

77, 77 to retract the slide rails 61, 61 within the housings 69, 60 and accommodate the

pins

63, 63 to engage the corresponding sockets 64, 64.

When it is desired to maintain the sashes l6 and 19 in the inwardly hinged open positions shown by dotted lines in Figure 1, a toggle link or other locking link arrangement (not shown) may be provided to hold the sashes in the desired angular positions.

it may be seen from the foregoing that a novel and improved form of window frame structure has been provided which the window is sealed by a slide rail extensible within a channel guide extending along the window jamb, and is locked by a spring urged bolt which is automatically withdrawn when the rail is extended into the channel for vertical movement therealong.

it may further be seen that the window sash may be slidably moved along its frame and held in position therein by engagement of the rail with the channel guide and may readily be pivoted about its locking bolts, to open the window, for ventilation and to enable the window to be cleaned from the inside.

it will be understood that the device of my invention is adapted for either metal or wooden sashes and frames, and that while two forms of releases are herein shown, the same releases are suitable for use in either the upper or lower sashes.

It will be understood that modifications and variations may be elfected without departing from the spirit and scope of the novel concepts of the present invention.
