Referring more in detail to the'drawings, the reference numeral lli designates in general the window'casing assembly which comprises the outer casing section or member Ii and the inner casing section or member I2. The section II, at its inner edge, is provided with brackets I 3 which provide a groove I4 to receive the tongue I5 of the section I2, and a U-shaped bracket I5 secured to the section I I,.adjacent the upper and lower ends thereof receives compression screens I1 which are mounted in thesb'racket I8 and bracket I9 respectively, which are secured to the section I2 inwardly of the outer face thereof.

'I'he section Il, at its outer edges, is placed in position, and the conventional sheathing 2i), insulation 2| siding 22 and caulking 23 is employed to finish the interior appearance of the dwelling in which the assembh7 is positioned. The inner section is sealed by conventional plaster 24 while 1 Claim. (Cl. 268-122) 2 the remainder of the dwelling is of conventional structure, as shown at A.

The bracket I9 forms a portion of the box assembly or housing 24 to house the lift mechanism 25, the remainder of the housing 24 being formed on the section I2 as shown at 25.

In Figures l and 2, the lift mechanism 25 is shown as comprising opposed disc shaped gears` 21 and 28 respectively, which are fixed to the inner ends of

shafts

29 and 35 respectively, and these shafts are journalled in brackets 3| fixed to the bracket I9 within the housing 24. The

gears

21 and 28 are provided with the row of openings 32 to engage the teeth 33 of the disc gear 34 mounted intermediate of the gears 21 and Z8 on the shaftfl, the gear 34 beingfixed to the reduced portion 35 of the shaft 4|, and akey 35 in the key slot 31 in the portion 35 retains the gear 34 in position by means of the springwasher 38. The portion 35 of the shaft 4I is journalled in the bracket I9 at one end, and

bearing washer 39 and cotter key 45 retain the v shaft 4I so that the outer flanged end 42 engages the housing 24. A bore 43 in the outer end of the shaft receives the re-duced portion 44 of the crank arm 45 and spring pressed balls 45 in the portion 44 engage in the seats 41 in the inner surface of the bore 43 to retain the portion 44 in the bore 43 for the rotation of the gear 34.

Fixed to the outer ends of the

shafts

29 and 30 are disc gears 48 having teeth 45, which are similar to gear 34, and the teeth 49 of the gears 48 engage in the openings in the gears 50, which are similar to

gears

21 and 28.

The gears 50 are iixed to the lower ends of the jack screws 5 I, there being one in each side of the section I2, the lower ends of the screws 5I being mounted in the ball bearing supports 52 and the upper ends journalled in the bearing seats 53. Brackets 54 retain the screws 5I in vertical relation to the

shafts

29 and 34 within the section l2. Mounted on the screws 5I are the traveling nuts 55 to which is secured the linkage guide arms 56 which travel in the slots 51 during the movement thereof, and also engage the linkage position rollers 58, mounted on the bolt shafts 59 and spaced from the sections I2 by bushings 50 on the bolt shafts 59, which are secured as shown in Figure 5. The arms 55 are provided with a forked end 5I which receives the reduced end 52 of the link 63 and a pin 64 pivots the link 53 in the end 5I of the arm 55. The other end of the link is similarly shaped, having a reduced end 62 which is receivable in the apertured ears 55 of the bracket 65, and a pin 51 pivots the link 63 in ears 55 of the bracket 5B.

The assembly thus describedA is provided at each side of the casing assembly ID, and each bracket 65 is secured to the lower window sash 61 by fasteners 58. Sash 61 has upper and lower rails 69 to which are secured plates 1B carrying sash glass channels 1I for mounting the inner and outer panes 'I2 and 13 respectively.

The rails 59 each `carry a spring loaded seal assembly which comprises a substantially U- shaped bracket i4 which is secured to the rail 5S by a fastener 'l5 which also secures the plate 'i9 to the rail, longitudinal extending opposed baille plates 'i6 engaging the bracket 14 which is engaged by the substantially U-shaped sealing means il which extends outwardly of the rails to engage the lower rail 78 of the 'upper sash 19, and the sill portion 80 of the section Il, and this assembly, its use and construction is fully described in my co-pending application for Door Seal Assembly, filed November 30, 1945, Serial No. 632,006, which issued as Patent No. 2,445,315.

The upper sash i9 is also constructed in similar manner `to the lower sash, except that the seal assembly is only in the upper rail 80 of the sash.

The upper sash is provided with a sealing or guide stop 8l which is secured to the section l2, and terminates just above the lower edge in a bevelled edge S2, which permits the lower sash to slide past the upper sash in its upward movement, while the guide strip 82 for the lower sash extends upwardly from the lower rail at an inclination to terminate at its upper end adjacent the top of the section I2.

The upper sash is xed in its closed position, and is provided on the bottom of the lower rail with a drip ledge 83, which prevents water entering the space vbetween the upper rail Aof the lower sash and the lower rail of the upper sash.

A screen guide channel 84 secured to the section H carries the screen 85. The screen is provided with a spring pressed latch 89 mounted in the recess 8l of the screen and receivable in the groove 88 in the guide 84 to retain the screens in raised position.

The window casing assembly is provided with rubber corner pad assemblies 89 to prevent leakage of the casing, and a crank storage bracket 90 may be secured to the section l2, as shown in Figure 6.

The assemblies shown in Figures 6 to 9 inclusive are similar except that gears 49 and 50 are replaced by bevelled gears 9| and 92 respectively, and gears 2l, 28 and 33 are replaced by similar

shaped gears

93, 94 and 95 respectively, andthe shaft 95 for gear 94 is journalled in vthe ball bearing mounting 9T and a washer 93 welded to the rear of section I2 retains the shaft 96 loosely mounted therein, while a nut and washer assembly 99 retains the gear 94 on the shaft 98 and the crank is connected to the shaft B as previously described, with regard to shaft 4 i `In Figure 9, the nut 55 carries a stud Ille, which engages the elongated slot l! Ain the `link |62 while the slot |03 in the other end of the link i 92 enga-ges the stud |104 in the bracket 155 which is xed to the sash El. This is a modied form of linkage, and can be substituted for the linkage previously described.

With the casing assembled as described, providing the closing effect of two flanges, perfect alignment is had at all times.

By turning the crank 45, the 'linkage pulls the lower sash rearwardly at the lupper edge thereof, so that it will slide upwardly inthe rear of the upper sash. The rollers 58 guide the links `B3 so that the sash is pulled rearwardly to move upwardly, and pushed forwardly into closed position when lowered. The nut 55 travels on the jack screw 5|, raising and lowering the sash as desired, in a simple, easy and efcient manner.

The seal shown included in the sash rails provides an air tight Seal at the point of contact, so that the sash, with its double panes of glass, functions as an eflicient storm window.

The linkage arrangement prevents opening of the lower sash, making it burglar-proof, and the drip ledge on the upper sash contacting the upper edge of the screen prevents insects from entering at the top of the screen.

From ythe foregoing description, it is believed that the construction and operation of 'the as.; sembly will be apparent to those vskilled I.in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination vof parts .may be resorted t0. provided they fall within the spirit of the inven-v tion and the scope of the appended claim.

Having thus described the invention, what Eis claimed as new and desired to be secured by Letters Patent is:

"in an operating mechanism for a window frame and upper and lower sash assembly of the sliding type wherein the .sash are in vertical'alinement with each other, the improvement comprising a pair of vertically disposed jack screws mounted at opposite sides of the assembly, a travelling nut on each jack screw, a pivot on the lower sash and a pivot on the jack screw, guide slots in said frame for the pivot on the travelling nut, rollers mounted on the frame adjacent said guide slot for coaction with said pivot a link connected at its opposite ends to said pivots, a `gear on the travelling nut on the lower .end `of each jack screw, a pair of horizontally disposed .shafts provided with gears on both ends thereof, gears on one end of said shaft ends engaging the gear on the jack screw and the gears on the other end simultaneously engaging a gear having an operating handle thereon so that when said handle is rotated to cause the actuation of said lgears said travelling nuts will be caused to rotate on said jack screws and through the medium of .said links will cause the lower sash to move forwardly of the upper sash and be raised into open position and upon lowering of said Ilower sash :said link will cause said lower sash to be moved into alinement with said upper sash into closed position.
