REVERSIBLE WINDOW Filed May 8, 1934 2 Sheets-Sheet 2 II IE. 5

Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE Claims.

My invention relates to reversible windows and in particular to an improvement over my previous Patent No. 1,767,022, in that I am simplifying the pivoting means and also incorporate a means 5 for locking the sashes as an integral part of the reversible windows.

One object of the invention is to permit its application to a steel sash with new means of locking the same.

Another object is to provide an improved pivoting means. Other objects will be evident from the following specification and its accompanying illustrations, in which:

Fig. l is a front plan view of the invention.

Fig. 2 is a sectional view taken on lines 2--2 of Fig. 1 but showing one window open.

Fig. 3 is an enlarged sectional view taken on lines 33 of Fig. 1 showing the sash locked in position.

Fig. 4 is similar to Fig. 3 but having the lock shifted to opening position.

Fig. 5 is an enlarged section taken on lines 5-5 of Fig. 1.

Fig. 6 is an enlarged fragmentary section of the lower sash.

Fig. '7 is an enlarged fragmentary sectional view of a locking chain device for locking the lower sash with the upper sash.

Fig. 8 is a fragmentary sectional view of the pivoting means.

Referring to the drawings; a window casing consisting of a head I0, jambs H and sill I2 is made to fit in an opening in the wall of a building, and a metal flange it formed on each jamb it produces a channel which extends the full length of the frame or casing between the head it and the sill l2.

An upper sash l4 comprising an inner angle l5, glass It and outer angle I1, and a lower sash I8 comprising an inner angle l9, glass 25 and outer angle 2 l, are pivotally movable within the frame or casing by means of long lever arms 22 and 22a and short lever arms 23 and 23a. Said long lever arms are pivotally attached near the lower end to the jamb H by screws 24 in such manner as to allow a free swinging movement of said arms; and the angular ends 25 of arms 22 and 22a act as a stop when the sash l4 or I8 is swung open, the ends 25 pressing against the channel l3. The short lever arms 23 and 23a have a lug 25 which forces the long lever arms 22 and 22a back to a perpendicular position when the sash l4 and I8 are closed. Short lever arms 23 and 23a are pivoted at 27 to long lever arms 22 and 22a, the opposite end of said short levers form'angular portions 28 and 280: which are pivotally attached to outer angles ll and 2| respectively, by pivot pins 29. Thus where the sash are opened or reversed they swing inwardly as shown by the lower sash in Fig. 2.

A pivot block 55 is split at 3! and has an aperture 32 in which a pivot pin 33 is inserted, said pivot pin having a flange 54 which is used as a thrust bearing between the block 35 and sash M or IE3 to which the pivot pin 35 is at- 10 tached. A tapered bolt 35 is screwed into the threaded top 35 of the block 35 to insure the proper amount of pressure of the block 30 against the sides of the channel l3.

A look comprising a box 31 with apertures 38 15 and 39 in the front and bottom walls respectively is provided with a sliding catch 45 with a spring bolt 4! fixed thereto and extending through aperture 42 in the top of said boX 51.

A spring 43 is coiled around the said bolt 4| :0 between the top of catch 45 and a washer 44 on the inside of said box. The catch 40 has a rounded end 45 under which a finger 46 of finger pull 4'! is mounted. Said finger 46 projects into the box through the aperture 35, the finger pull 2:! 41 being pivotally mounted between projecting ears 48 of plate 55 by means of a pivot pin 5i.

A second finger pull 52 with a split flange projection 53 is mounted over the projecting outer angle ll of sash l4 and attached rigidly thereto, 30 thus as finger pull 4'! is drawn down, finger 45 lifts the rounded end 45 of the tongue 45, compressing spring 43, and finger pull 52 can then be pulled inwardly thus opening the sash.

Attached to outer angles ill by bolts 53 is a 35 tapered channel 55 which presses into groove 55 in the head i5, when the sash is closed, and a slot 49 allows a slight movement of the channels 54 and. 52 to ensure a tighter fit in the grooves 55 and 54. A similar channel 52 with bolt 63 is also 40 mounted on each side of the sash l4 and I8 and attached to the outer angles 5 l and 25 and wedge into grooves 64 in jambs l l as shown in Fig. 5. These channels thus used form a weather stripping and seal the windows against inclement 45 weather.

A chain catch comprises an angle 56 attached to outer angle 2| of sash l8 and a slotted housing 57 mounted on outer angle I7 and inner angle I5 of sash M, a chain 58 attached to said angle 50 56 at one end and having a flanged anchor 59 attached at its other end, said anchor being slipped in or out of the slotted housing 51 as desired for looking or unlocking the sash. A spring clip attached to the outer angle I! of 55 the sash l4 and bearing against the flanged edge 6| of the outer angle 2| of sash l8 retain the sash l4 and I8 in a closed position, the flanged edge 6| of outer angle 2| forming a seal against the weather.

By lifting the latch 40 by means of the lever 41 the upper sash may be swung open, and reversed for cleaning if desired. Also by releasing the chain catch the lower sash may be similarly opened. In either case, the blocks 30 slide up in the channel [3 and the sash turn on the pivots 33, and are held in position by the levers 22, and 23, and 22a and 23a, respectively, the swing of the long levers 22, 22a being stopped by the contact of the faces 25 with the flange I3.

I claim:

1. The combination with a window frame and reversible sash, of a pair of levers connected at one end to the sash and pivoted at the other end to the frame, the last mentioned end projecting beyond the pivot to stop against the frame when swung to a certain position.

4. The combination stated in claim 3, said 10 means comprising a tapered screw fitting in the split.

5. The combination of a metal window frame the jambs of which have a flange forming channels, a metal sash reversible in the frame, blocks 15 pivoted to the sash and slidable in the channels, and jointed arms pivoted to the sash and to the frame and arranged to stop against said flange in either open or closed position of the sash.

LEROY B. TAYLOR.
