1 Claim.

This invention relates to windows and has for an object to provide a window the sashes of which may be easily adjusted to open position and when closed will reduce the air space around the window thus reducing fuel costs in cold weather.

A further object is to provide a window having the sashes formed of metal and provided with novel flanges adapted to inter-engage and prevent rain and dust from entrance into the 10 building.

With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood 15 that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a front elevation of a window constructed in accordance with the invention with 4 parts broken away and parts in section.

Figure 2 is a vertical sectional view taken on 25 the line 2--2 of Figure 1.

Figure 3 is a fragmentary perspective View of an I end portion of the lower shaft showing the guide strips at the end for engaging the parting stop.

Figure 4 is a detail perspective view showing one of the flanges on the parting stop for preventing entry of dust and rain and showing one of the racks.

Figure 5 is a detail elevation showing one of the racks in profile.

Figure 6 is a detail cross sectional view taken on the line 66 of Figure 1 showing the interleaved flanges of the window panels.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, I designates a conventional window casing having outer guide strips I I and a center parting stop I2 forming guide grooves for the upper and lower sashes or panels, the guide grooves being faced with felt I3 to receive the 45 side edges I4 of the upper and lower glass panels I and I6.

In carrying out the invention the lower glass panel I6 is provided at its upper edge with a metal channel I! and the upper glass panel I5 50 is provided at its lower edge with a metal channel I8. The flange I9 of the channel of the lower panel rests, when the panels are closed,

1 upon the flange 20 of the channel on the upper panel, as shown best in Figures 2 and 6. The

55 flange I9 is provided with a downwardly directed V-rib 2I which fits in a similarly formed groove 22 in the flange 2U. Felt packing 23 is arranged between the flanges and may be secured to either of the flanges to prevent access of rain and dust.

By referring to Figure 4 it will be seen that angle iron flanges 24 are secured to the parting stops 12 by screws 25 or other connectors, and are adapted to inter-leave between the flanges 2| and 22 of the panels at the ends thereof and likewise prevent access of dust and rain. Each of the flanges 24 is provided with a downwardly directed V-rib 26 which is adapted to fit between the adjacent ends of the flanges 2I and 22 when the panels are closed and prevent access of dust and rain tothe building.

The lower panel I6 is provided at the bottom with a casing 21 having a channel 6 therein to receive the lower edge of the glass panel, the channel being faced with felt I to prevent entrance of wind, rain and dust. Each end of the casing is provided with a guide projection 28 to fit between the parting stop and associated outer guide strips, as shown in Figure 3. The casing houses gears 29 which mesh with racks 30 which may be countersunk in the guide strips I I and secured in place by screws 3 I.

For turning the gears to raise the lower panel 1 a shaft 32 is journaled in the casing at about the center thereof and is equipped with a crank handle 33. A sprocket gear 34 is fixed to the shaft within the casing. An endless sprocket chain 8 is trained at the center over the sprocket gear 34 and is trained at one end over a sprocket gear 35 which is fixed to the shaft 36 of one of the gears 29. The opposite end of the sprocket chain is trained over a sprocket gear 31 that is fixed to a shaft 38 which carries a gear 39 that meshes with the other gear 29. Rotation of the crank handle moves the chain to rotate the gears 29 and raise or lower the window with ease, the window remaining in adjusted open po sition by the latching engagement between the gears and the racks.

For adjusting the upper panel the same is equipped at the top with a casing 40 having a channel 4| in the bottom faced with felt 42 to receive the upper edge of the glass panel and prevent entrance of wind, rain and dust. A feed screw 43 is journaled at the ends in bearings 44 on the inner end walls of the casing, the feed screw having right and left threads 45 and 46 upon which traveling nuts 41 and 4B are engaged. Links 49 and 50 are pivotally connected to respective traveling nuts and are pivotally connected at the upper ends to brackets 5| and 52 which are secured to the top of the window casing.

A worm gear 53 is fixed to the shaft and meshes with a worm pinion 54 that is mounted on a stub shaft 55 which is equipped externally of the casing with a lever 56 by means of which the shaft may be rotated to rotate the shaft 53 and advance or retract the traveling nuts and move the links to raise or 'lower the panel.

From the above description it will be seen. that a window constructed as above described dispenses with the use of wood and will reduce the'usual air space around a conventional window with consequent reduction in fuel costs in cold weather. The felt faced channels on the panels and'in the window. casing prevent rain, dust and weather from entrance into the building. The upper and v receiving the rib, packing arranged between the flanges, and stationary angle iron flanges interleaved between the-ends of the first named flanges and provided withV -shaped ribs adapted to be re- 15 ceived in the first-named V-shaped groove.
