2 Claims.

The present invention relates to improvements in window construction and more particularly to mechanism for raising and lowering windows.

Oneof the objects thereof is to provide a simple, efficient and inexpensive means for eifecting the raising and lowering of the upper and lower windows of a building without the use of sash cords and weights.

Another object thereof is to provide improved means for the counter-balancing of one double hung window with respect to the other.

A further object thereof is to provide a sturdy, dependable window operating mechanism for counter-balancing the windows in such a manner that as one window is raised, the other will be correspondingly lowered in unison therewith automatically.

Another object thereof is to provide a new form and construction of window wherein sashes are provided only for the upper and lower edges of the windows and not for the vertical marginal edges thereof as well.

A still further object thereof is to provide means for weatherstripping the windows of my type of invention so that, while they are transversely spaced apart across the window frame, exclusion or atmosphere by the windows is made possible.

Another object thereof is to provide an alln metal window casement as well as sashes for the windows so characterized that a stationary housing extending across the plane of the upper edge of one window and the lower edge of the other window, when the windows are in closed relation, contains the operative part of the window raising and lowering mechanism.

With the above and other objects in View, my invention constists in the arrangement, combina'- tion and details of construction disclosed in the drawings and specification and then more particularly pointed out in the appended claims.

In the drawings,

Wherein similar reference characters designate similar parts throughout the respective views,

Figure l is a vertical sectional elevation of my invention,

Figure 2 is a section taken on line 2-2 of Figure 1, looking in the direction of the arrows,

Figure 3 is a vertical section taken on line 3--3 of Figure 1,

Figure 4 is a section taken on line lli-t of Figure 1.

In the drawings, which are merely illustrative of my invention, all the parts of the invention are made to appear.

The present invention of window construction contemplates balancing the upper window against the lower window by means of gearing and a friction lock. The use of weights and counterweights commonly employed for this purpose is discarded in favor of a counter-balancing feature which assures, at all times, positive holding in adjusted position of one window with respect to the other window.

In this type of window construction an allinetal frame construction for the upper and lower windows is made use of. The wooden frame into which the metal frame is mounted is generally designated iii, Figure 1.

The metal jamb and frame furnished for use in connection with the present invention is generally denoted at il. It is a, rectangular hollow body. This metal body, on the side of the frame facing outside of the building, is shaped to provide a transversely extending lower surface or narrow ledge i2 and an Lipper one i3, these being connected by vertical portions lil and l5, Figure 2. This produces a rectangular frame which is formed as the outermost body o the complete all-metal window jamb. This body is formed integrally with a pressed out or indented rectangular, channel-shaped hollow stop member, disposed at right angles` to the width of the jamb. These channel-shaped stop members have outer walls or anges i6, rear spaced walls I9 and right angular connecting walls il which are formed parallel with the walls l and i5 of the window frame. The channels in these stop members are designated IS.

The oppositely arranged vertical side walls of the vertical frame are designated 26, 2l and the top and bottom walls connecting same, in a plane in advance of the stop members are designated 23, 2li. An examination of the bottom structure of this window jamb shows that the bottom wall 213 preferably inclines downwardly from the front to the rear plane thereof. It also reveals that a depressed channeled integral portion 25 runs completely across the jamb transversely thereof at 25 in its front plane, made in one piece with the frontmost bottom portion 2l. The channeled portion 25 is formed with a coextensive channel 25 opening into the interior of the jamb.

The upper surface of the transverse ledge 2l at the front of the lamb is designated in Figure 2 as 2l. rlShe lower window panel is located here.

/The upper window panel is spaced apart from the lower one transversely of the jamb a slight distance so as to be disposed in parallel relation. I provide a pair of vertically extending stop members and mount them contactingly against the portions of the side walls 28, 2| of the vertical jamb or frame which front on the ledge 21. The stop members are secured by screws 28a to these parts of the jamb in such a manner that their inner flat surfaces form the stops proper for the lower window panel, while their right angular back side portions 38 overlie side walls 28, 2|, and their inner side portions 28 jut out in parallel relation to the side walls 28, 2|.

Between the stop members 6, |1 and 28, 29 are located intermediate stop members also of channeled-out construction so as to provide confining means for the upper and lower window panels against these stop members. Each channeled intermediate stop member is a Vertical metal body 3| and 32 arranged to Contact the side walls 28, 2| of the jamb. The right angular flanges 35, 35a, and 36, 36a of the two vertical channeled stop members now being described are arranged in parallelism and are spaced away from the adjacent portion |9 of stop members I6, |1, and the adjacent portion 29 of stop members 28, 29. In this way tracks are formed vertically of the jamb for the window panels to adjustably slide in.

The parallel right angular flanges 35, 35a, and 36, 36a of the stop members 3| and 32 terminate in right angular inwardly extending abutments 33, 33a, and 34, 34a respectively. The channels in these stop members are designated 31 and 38 respectively. Screws 41 secure these stop members against the Vertical side walls 20, 2| of the jamb.

I provide suitable weatherstrips for use in conjunction with the window panels or panes. Right angular angle iron strips are interposed between the top rear window panel 8| and the stop members i6, l1, and similar angle iron weatherstrips are interposed between lower front window panel S and the stop members 28, 29. One weather strip has one side 40 overlapping side 25 of the jamb, extending the full length thereof, being operatively secured thereto. The other and right angular ange 42 thereof contacts side |9 of the stop members I5, i1.

The other angle iron weatherstrip has one side 46 overlying operatively side 28 of the vertical jamb, and its right angular side 44 overlying the portion a of the intermediate stop member 3l. It will be noted that the side of one weatherstrip also extends so as to abut the inturned portion 33 of the stop member 3|, while the side 46 of the other weatherstrip also extends so as to overlie the edge of portion 29 of stop member 28, 29.

On the other side 2| of the jamb are similar weatherstrips to those just now described in connection with side 26 of this same jamb. One weatherstrip has the right angular sides 39 and 4|, of which side 4| overlies portion I9 of stop member I6, |1, while side 39 overlies side 2| of the jamb and by its other face abuts inturned portion 34 of the stop member 32. The other weatherstrip has one side 43 abutting the portion 36a of the stop member 32, and another right angular side 45 abutting side 2| of the jamb and also the edge of portion 29 of stop member 28, 29. Number 49 designates the elongated part of either channel 3'! or 38 of the two vertical intermediate stop members 3| and 32, while the corners thereof are designated 52 and 53 respectively, Figure l.

Fitted snugly into the channels of these stop members so as to ll the elongated portions 49 as well as the corners 52, 53 of the channels 31 and 38 of both stop members are metal inserts 5D and 5| respectively. I provide a substantially oblong rectangular housing or case and locate it across the width of the window frame centrally thereof. This housing is composed of the vertical oppositely arranged side walls 54, 55, the integral top and bottom walls 56 and 51 respectively disposed at right angles with respect to side walls 54, 55. The side walls 54, 55 as illustrated in Figure 2, terminate short of the full width of the jamb, but the top and bottom walls 56 and 51 are shown partly in Figure 3, extend up to the plane of the vertical stop members 3| and 32, where they are formed with right angular flanges 6| for the top wall and 63 for the bottom wall. These anges 6| are secured by screws or other fasteners 62 to the side 32 of the Vertical stop member 32, and side 3| of the member 3|. The anges 63, however, extend into integral odset portions 64 formed upon these parts of the stop members 3|, 32.

Reference being made particularly to Figure 3, it will be observed that the metal inserts 5| in the vertical intermediate stop members 3| and 32 have the inner ends of pinion shafts 52 and 53 extended into them, which shafts also project into walls 32 of these stop members. The major portions of the shafts 52 and 53 however, extend into the housing. A pair of pinions 64 are made fast upon shafts 52, 53, at the outermost ends of the housing. The outer ends of the shafts 52, 53 extend into and are journaled in the blocks 54a which are frictionally contacted with side walls 54, 55 of the housing as shown in Figure 3.

It will be seen that rollers 65 engage circumferentially the shafts 52, 53 and the inner circumferences of the holes of the pinions 64 into which these rollers extend. This provides antifrictional bearings for the set of pinions. The interior of the housing is designated 51a.

The diagonally opposite corners of the top and bottom walls 56, 51 (Fig. l) of the housing are indented. Thus, an angle iron offset integrally connects and intervenes between the corner connecting wall 54 and wall 51 of the housing, and wall 56 and wall 55 thereof. The portion 58, 58a of each angle iron offset is disposed parallel to walls 56, 51 of the housing, being formed at right angles upon walls 54, 55 of the housing. Similarly, the other right angular part 59, 59a of the angle iron parts are disposed parallel to walls 54, 55 of the housing being formed at right angles to walls 56, 51 thereof and also upon portions 58, 58a of these oisets. By extending the terminals of walls 54, 55 beyond oiset portions 58, 58a of the offsets, parallel to portions 59, 59a thereof, grooves 60 68a are provided diagonally of the housing, which extend coextensively with the walls thereof. It will be seen that groove 68 opens out upwardly of the housing while groove 68a opens out downwardly thereof.

The upper window panel is designated 88 and the lower one 8|. They have no vertical sash parts lining their opposite vertical edges. An upper and lower sash, however, is fitted upon the horizontal upper and lower edges of these window panels 88 and 8|. They are made preferably of metal. Arranged vertically near the Vertical side marginal edges of the window panels 68 and 8| are vertical rack bars 66 and 61 respectively which have their inner faces operatively secured in contact with the confronting sides of the panels 88 and 8|. The upper ends of these rack bars 66, 61 are secured to the upper sashes of the window panels 80, 8|. These sashes will now be described. The teeth of the rack bars are designated 68.

The lower sash bar is a dual recessed body formed by providing three right angular iianges 72, 'll and 10 upon the length of the base portion 69 thereof of graduated lengths, of which fiange 'I2 is the shortest and flange l0 is the longest. This produces a recess 'I3 between flanges 'Il and |53 into which the lower horizontal edge of the panel 80 extends and is held airtight in puttied relationship to the sash as at 13, contacting the flanges 'Ill and 1| snugly. The other recess T4 between flanges 1|, 12 of the sash extends coextensively along the length of the sash and opens out upwardly therefrom.

The upper sash bar is a single recessed metal body having the spaced apart lateral flanges 1G, 'Il formed as offset lateral portions upon the centering shank 'l5 of the sash bar which projects above the window panel 8U. Between anges 16, of this upper sash bar i'lts the upper horizontal edge of the window panel 80,

being held therein in puttied relationship as at 19. There is a right angular extension flange 'i8 projecting forwardly from the upper sash bar. The vertical rack bars Sii are secured at opposite ends to portion 1B at one end, and to portion 69 at the other end of the panel 8D.

At the upper horizontal edge of the lower window panel 8| is a part exactly similar to sash bar shown fitted to the lower part of panel 80,' except that it is reversed in position so its recess Ma opens out downwardly of the panel 8|. The three graduated flanges are designated 10a, 'Ha and 12a'. The upper edge of panel 3| is held fast in the recess between flanges 19a, 1|a in puttied relation thereto, or otherwise. At the lower end of the panel 8| is fitted another sash bar, the base portion of which is denoted at 33. Parallel respectively long and short sides 35, 81| are formed right angularly in spaced apart relation upon base portion 83 of this sash bar. The long side B of this sash bar projects Vertically below base'portion 83 providing a tongue, while its upper end is turned outwardly at right angles as at 81 to provide a handle hold for raising and lowering the lower window panel 8|.

For the purpose of holding the window panels 8|) and 8| in adjusted position when they have been opened, or to hold them against opening when they are shut, I provide a special form of locking means therefor. This is illustrated in Figures l, 3 and 4 particularly. Number 9B designates the opposing vertical side edges of each panel.

The top wall 5S of the housing is formed with an elongated slot 9| in a plane with the ilange 6| of the housing through which the teeth of one pinion S4 are exposed, in line with the slot, each in succession, and so are the slots between the teeth of this pinion. Projecting snugly into this slot 9| is the shank 93 of a detent having a head 94 which slidably overlies a washer of rubber or the like material 95 by which it is spaced above top wall 5B of the housing movably. The shank 93 is formed with a narrow-shaped barb S2, the inner parts of which slidably abut the under face of top wall 56 of the housing. It will be seen that the barb 92 of the detent projects with its lowermost point below the periphery of the pinion 64.

The use and operation of the invention will now be detailed. It will be seen that the rack bars the window panel 8 6 and 6l are disposed between intermediate vertical stop members 3l and d2 and the blocks 54a, fitted frictionally in the ends of the housing proper. Also it will be seen that the main body of this housing is fixedly located between panels and 3| with their opposing vertical sides 5d, 55 facing these panels, and with the ends of these sides disposed in close proximity to rack bars t6, 6l. The vertical marginal edges Si) of the window glass panel Si snugly slide rubbingly against sides 4i, [l2 of the weatherstrips and also against sides 3S, it thereof, and also slidably abut the portions 35, 36 oi the vertical stop members 3|, 32. The other glass panel 8G has its vertical marginal edges SG slidably bear against sides di, 4G and 43, 5 of the inner and lower weatherstrips, and also bear slidably against the portions 29 of stop members 28, 29. In this way outside air is shut out from innltering into the room, the windows of which are equipped with my invention. l

By taking hold of the handle @l on window panel 8| at the lower part of the window jamb and raising this panel, rack bars SS or @l thereof move upwardly, so the teeth 63 thereof mesh with pinions 6d in the ends of the housing. This turns the pinions clockwise causing the teeth thereof to mesh with the rack bars on the other panel 8@ `which is the upper rear panel of the jamb. Normally, when both window panels are in closed relation, the upper ends of rack bars on lower panel and the lower ends of rack bars on upper' panel Sli mesh with diametrically opposite points of the pinions 64. Hence, when lower front panel 8| is raised, and the pinions turn clockwise, the rack bars on panel 8i] move downwardly causing upper back panel Sil to move downwardly automatically. In the same manner by pressing down upon handle 8l and lowering window panel 8| the other panel Sii may be caused to move upwardly. Having'opened the two panels 8U and 8| adjustably, the user takes hold of washer and slides same upon top wall 56 of the housing in the direction of flange 5| (Fig. 3), and the pinion thereadjacent permitting, he causes the barb 92 of the detent thus slid in its slot 9|, to project in one slot between two teeth of this pinion so as to lock this pinion against rotation. In this manner the two winn dow panels 8E and 8| are locked against accidental movement in their tracks. It will also be observed that this affords a burglar proof window construction since manipulation of the outer panel Bil is frustrated if nefarious movement is desired from outside of the jainb, since both panels are locke-d by means of the detent applied as explained.

When the window panel 8| moves downwardly as far as it can go into fully closed position, the tongue 86 of this panel projects snugly into recess 26 of the jamb upon the bottom threshold 21 thereof, and when this same panel has been moved thus into fully closed position, the flange 12a of its upper sash bar will project snugly and be received in the recess di) of the upper end of the housing. In this manner an airtight seal is had for both the upper and lower portions of When the upper rear panel 80 is moved upwardly into fully closed position, the marginal edges e@ thereof have entered snugly the guide track 89a of the jamb, and the top horizontal edge 86a of this panel 8d engages deflected part B9 of a spring weatherstrip se- Theipanel '8l in reaching its lowermost position had also engaged deflected portion 88 of a weatherstrip.operatively secured to the lower sash bar thereof, had flattened this strip and made an airtight seal at this point of the panel 8E,

It will be noted that the present metal window construction is adapted to be applied in proper use upon or within an old frame already in use or a new frame placed in the building in the course of construction. It could be applied in connection with the studs in the walls or with respect to the blockings in a masonry wall. The invention has the advantage that the upper sash is automatically lowered at the top, when the lower sash is raised.

I do not mean to conne myself to the exact details of construction disclosed in the drawings and specification, but claim all variations set forth in the appended claims.

What I desire to claim and patent is:

1. In a device as described having a vertically disposed channel member including a web and inturned base anges, and a window frame side against which the base flanges of said member are secured; a hollow cross beam having one end secured to but opening out into the channel member so as to be closed by said channel member, blocks snugly tted in each end of said channel member in the channel thereof, pinions, pinion shafts projecting into and journalled in the web of the channel member and the blocks therein,
