METAL WINDOW.

Application iled December 10, 1926. Serial No. 153,776.

This invention pertains to metal window construction.

One of the objects of this invention is.V to provide an improved window construction whereb the fit of the sash may be adpisted. Anot er object is to provide an improved construction in which the friction of the sash isreduced. 1

Another Object to provide a construction which will conceal and protect the sash cord.

Another object is to provide an improved `construction which will bey cheap to `manufacture and which may be adjusted to suit the peculiarities of each installation.

Another object is to provide anV improved construction adapted to render the traine stiff so as to withstand lateral pressure of thesash. i l

Further Objects will appear from the following description, taken in connection with the accompanying drawing, in which `Figure 1 is a vertical section showing a window embodying this invention; I

Figure 2 is a section on line.2-2 of Figure 1;

Figure 3 is a perspective detail of the auxiliary jamb; and

Figure 4 is a Aperspective detail of the anchor for the inside stop fastening.

Referring to the drawing, Figure 1 shows a vertical section of the window and the frame, which comprises a lintel 1, a sill .-2 and vert-ical jainbs 3,1 only onev of which is shown in thef drawing. The lintel 1 has a channel form provided with inner and outer flanges 4 and 5. i This lintel is formed with an inwardly extending channel or groove 6- and adjacent thereto a. downwardly extend-V ing flange or rib 7. The sill 2 has a channelled form, which may have `any suitable shape, .such as illustrated in Figure 1.

Each jamb 3 has a rectangular box forni,

as shown in Figure 2, and is provided withV an inwardly-extending flange 8. `The outside of the box vis closed by a plate 9, having an inwardly directed flange 10, which forms the outside stop whichy guides the upper sash. The plate 9 may be crimped to the jamb 3 -on the outside, as shown at 11, and is also secured to the flange 8 by means vof rivets 12 or other suitable astening.- A gutter 13 may be secured to the outer flange 5 of the lintel and run down the outside face of the `15 similar to that described for the jainb, as illustrated in Figures l and 2. The inner edge of the flange 10 forms the Outer stop which guides the upper sash 14.

Thesash V1li may also be of metal andv has Vits stiles formed with an outwardly extending rib 15 adapted to cO-operate with the flange 10 to guide the sash. An inner guide for the rib 15 is provided by a flange 16 formed or mounted on an auxiliary jainb indicated generally at 17. The auxiliary )amb v17 has a generally channelled form' but is provided with an inwardly extending channel 18, running along the middle thereor. This channel is slightly wedge-shaped and eiicloses an inverted U-shaped channel 19, which serves to fill out the inner part of the channel 18 and stillen the saine. lFrom the channel 18, sloping webs 20 extend outwardly to both sides, terminating in right angle flanges 21. The flanges 21 are adapted to bear against the inner `face of the jaiiib 3 and have mounted therein at intervals therealong adjusting bolts 22. vThe bolts extend through sides of the jainb with the head of the boltv against one flange'and as- `cessible for adjustment while the nut is against the other flange.

, Mounted on the inner face of the channel 18 is a plate 23, whose edges are each bent or deflected at obtuse anglesvto form the flanges 16. The flanges 16 may be straight,

but, as shown in Figure 3, they taper so as to startat the middle of the jamb 17 and iiicrease iii width toward 'opposite ends, merging into the plate at the middle.V The deflection of the flanges as well their is shown exaggerated, for in practice both will be slight. i i

The inner sash 24 is provided with a rib outer other is, in inner other sash 14. This` rib 15 engages the flange 16 of the auxiliary jamb and turn, engaged by a flange on an stop 26. The stop 2 6, as well as the parts above mentioned, may be constructed of pressed sheet metal and has an outer flange 27, which rests against the jainb13, and an inner lange 2S which rests upon the edge of the auxiliary `iamb 17 and serves to clampthe saine against the janib 3 while centered therein. The stop 26 is secured in place by clamping bolts 29, having threaded engagementv withclips `30 on the exposed face of the jainb. These clips are slipped the sash.

under the projecting ends of pairs of holding lugs 31, cut from the inner face of the jamb 3 and bent inwardly, as shown in Figure 4. This permits the stop to be adjusted towards the sash, the clips sliding between the lugs. The auxiliary jamb has cut out portions to clear the clips, as shown in Figures 3 and 4.

The meeting rails of the sashes may be provided with flanges 32 and 33, as illustrated in Figure 1. The upper rail of the outersash is arranged to abut the flange 7 on the lintel when the sash is up. The top rail of this sash may be provided with an upwardly extending flange 3-l,which enters the channel or groove (3 so as to provide a weather seal. The sash weights 35 may be connected by sash cords, running over pulleys 36 and connected to suitable fasteners 37 on the ribs 15. vIt will be noted that the

stops

10 and 26, together with the auxiliary jamb 17, form an enclosure within which the sash cords operate.

It will be noted that the sloping webs 2O give the auxiliary jamb an arched form with the bearing flanges 21 spaced laterally from the crown of the arch. This arched form with spaced bearing points gives great stiff'- ness to withstand lateral pressure from the sash in either direction. The bolt 22 serves to further brace and stillen the arch. 'Ihe plate 23 is carried by the arch and provides a. parting stile between the upper and lower sash.

In assembling this window, the lit of the sashes may be adjusted lby adjusting the auxiliary jamb 17. This is done by means of the bolts 22, before the stop 26 is in place. By drawing the flanges 21 together, the plate is sprung towards the sashes, and `by proper adjustment of these screws, the flanges may be sprung to cause them to hear evenly against the sash edges. The flanges bear at their edges so asto not only reduce friction but also to scrape as little paint as possible from the metal oli' the sashes. It will be noted that these flanges bear against the corners between the sash edges and the ribs so as to secure location of the auxiliary jamb, which is retained by the flange 28 of the stop 26.

lVhere the flanges 1G taper from the middle to the ends ot the jamb, any channel 38 formed will'be closed; for by drawing together the sidesby the bolts 22, the middle, where the flanges 16 disappear, will be brought into engagement with the edges of This provides a seal against the passage of a draft through the space 38,

It will be seen that by the present construction not only is the window rendered weather-tight all around, but the moving parts are all housed so as to be hidden from view and protected against deterioration. Furthermore, the various parts are adjustable in such a way thata proper running fit may be provided between the sash and its guides and at the same time a weather-tight joint is n'ovided.

It wil also be noted that the portion 18 ot the auxiliary jamb forms a parting style on which the bearing plate 23 is mounted. This parting style is relatively narrow while the auxiliary jamb has a broad bearing on the main jamb, so that a stilll and rigid parting style is provided which is not subject to warping or distortion by the forces acting upon it.

It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.
