Fig. 2 is a side elevawhen sliding. On the window-frame, oppotion of one side of thel frame. Fig. 3 is a versite the position of each sash when closed, is tical central section of Fig. l. Figs. 4 and 5 a metallic way 17, Fig. 5, which is provided 5o are perspective views of the movable and with apertures 18 for attachment and slot 19. loo
for the locking-cam. Each one of these ways 17 is preferably formed of bent sheet metal and is formed with a longitudinal wedgeshaped channel 20, in which the wedge fits, Figs. G and 9, and the parts are proportioned so as to make a tight iit between them when the sash is in closed position, but by reason of the tapered form they will immediately become loose at the outset of movement. Extending on either side of the channel 2O are inwardly-prejecting walls 20 and outwardlyprojecting flat portions 21 for the purpose of giving ample room for the window-sash to move without contact with the frame-stop. On the inside edge of one of the faces 21 is formed the dividing-bead 22, which is located so as to separate the sash. rlhe upper and lower ways 17 are identical in form, but reversed in position, and when they are placed on the side of the frame the beads 22 of the upper and lower sashways are brought into coincidence in such a way that they practically form a continuous bead from top to bottom, one or both being cutaway to form a it and to allow the channels 2O to overlap. (See Fig. 2.) lf desired, the metal bead 22, which is formed by folding the metal upon itself, may have a wooden lilling 23, and this wooden filling may be utilized, if desired, to connect the meeting ends of the beads, it being allowed to project at one end, as shown at the upper end of Fig. 5. The ways 17 may terminate at such points as to permit the sash to be removed from them when slid to open position, and for this purpose the wall portions may terminate short of the bead, so as to leave a projection of the latter, as shown at the lower end of Fig. 5. The edges of flat portions 21, which are presented outward on the lower ways, are preferably faced by the window stop-bead 2G, while those on the upper sashways, which are presented outward, abut against any suitable strip, such, for instance, as a strip 27, which I have shown adapted to hold screens or storm-sash, as will now be described.
In attaching the outside screen or stormsash the important objects are to do so without interfering with the movement of the window or shutters and secure close joining, while permitting movement of at least the lower one. I accomplish the above objects and I adapt screens or storm-sash to windowframes of ordinary construction without special Iitt-ing otherwise than grooving strip 27 to receive tongues 28of sash 29, which tongues are of metal and attached as shown in Fig. 10. The upper portion of strip 27 is cutaway, so that the tongues 28 of the lower screen or storm-window are released and the sash may be taken out or placed in position when the sash is up and then drop down into sliding relation in the groove below. This provides for a sliding lower sash for either screen or storm-window. After this is inserted the upper screen or storm-sash is fixed in position by its tongues 30, which bridge the outside edges of strips 27 and top plate 31, behind which it enters, while suitable catches 32, carried at the lower corners of the screen or window, enter sockets 33, formed in strips 27. By having the metallic tongues 30 of the upper screen or storm-sash bear against the outside of strips 27 they brace the part against inward movement, while the top plate 31 and catches 32 sustain it against outward movement, and the lower portion may slide up uninterrupted. This construction makes both sash conveniently removable.
To make a tight connection, metallic packings 34, Fig. 11, are located between the meeting-rails and between top and bottom rails and head-Stiles and sills, as shown in Fig. 3, secured along one edge and projecting up, so that they will be compressed and make a tight joint as the sash come to rest in closed position. These packing-strips are substantially alike in all the places, though they may be adjusted as circumstances may require. In mounting the locking-cam a mortise 35 is formed in the window-stile 36, Fig. 0, so that the toothed cam 8, hereinbefore referred to, can swing therein. As stated, the shaft 10 of cam 9 carries on its outer end a counterbalance 11, which hangs normally so as to keep the cam in position for engaging the window-sash. The size of the mortise 85, however, is such that the counterbalance 11 may be swung around, so as to move the cam away from the sash until the said counterbalance passes over its shaft and brings the cam to rest in a position away from the sash. The cam 9 works through a slot 19 in the way 17 and bites into the hollow side of the sheetmetal wedge 15 in controlling the sash, and this greatly increases the durability of the parts by avoiding wear on wooden surfaces. It is for this additional purpose, also, that the wedge 15 is made hollow, as shown, and attached to the sash with its open side presented outward.
Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
1. A window-frame comprising stiles having inner and outer metallic ways, each formed with tapering channels receding from the center, with inwardly-projecting walls, and with outwardly-extending .fiat portions; substantially as described.
2. A window-frame comprising stiles having inner and outer metallic ways,each formed with tapering channels receding from the center, and inner and outer sashes provided with metallic wedges, each formed with tapering channels receding from the center; substantially as described.
3. A window-frame comprising stiles, having metallic ways provided with slots, sashes having metallic guides and toothed cams projecting through the slots in the ways of the stiles, substantially as described.
4. A window-frame comprising the stops, the ways having tapering channels and lo- ICO IIO
rsvadise` ated between the stops, and the-sashes having Wedges Working in the channels ofthe Ways; substantially as described.
5. A metallic Way formed with a tapering channel, With inWardly-projectin g Walls, With outwardly-projecting flat portions and With a parting-bead; substantially as described.
G. A metallic sash-guide in the form of a Wedge having a tapering channel and outwardly-projecting Walls; substantially as described.
7. In combination With a window-frame, the grooved strips 27 having the upper portion of the groove cut away in each strip, the sash having attached on one face, metallic llanges Working in the grooved strips, an upper sash having metallic flanges bearing on `sash or screen Iivtting between the strips, engaged at its upper end behind the top plate,
provided with side flanges which bridge the said strips and secured at its bottom by catches, substantially as set forth.
