Serial No. 190,603.

of my invention is to pro- 10 vide a construction in which the sash may be made up as a continuous unitary structure, without requiring` separation thereof into two or more parts for insertion of the glass therein.

A further object isto provide a construction in which the glass may be removed or replaced while the sash `remains in its usual operative position Within the window casing.

My invention further relates t-o the provi sion of simple and convenient locking means for holding the glass in the Sash, tothe provision of effective cushioning devices for the glass7 to an improved sash construction and to certain arrangements and combinationsof parts which will be hereinafter described and more particularly pointed out in the appended claims. Q

locking Referring to the drawingsmy improved metal window sash comprises frame members 20, which are permanently assembled to be Continuous around the entire sash. These frame members are preferably made up of Sheet brass or other suitable metal, bent or pressed to the cross sectional outlines indicated in Figs. 2, 3, and 4.

While I have indicated the frame members 2O as made from a certain number of piecesl of sheet metal, it will be understood that the construction may be varied and that the different frame members may be made of one, two or more pieces of sheet metal as may be preferred under different conditions.

I preferably provide recesses 2l in the frame members 20 to receive corner pieces 22 (Figs. 6 and 7) which fit snugly in said recesses and firmly retain the frame members in accurate alignment, also stiffening and strengthening the sash at the corners thereof.

Fig. 2 shows a section of one of the side frame members, with the sides of the frame member extended outward, as indicated at 243 to provide extensions at each side of a sash guide Qlmounted on a casing frame 25.

In Fig. 3, I have shown a cross section of the top frame member, with the sides of the member bent inward and locked together to form a smooth continuous top edge for the frame, as indicated at 26.

In Fig. Ll, I have shown a cross section of the bottom frame member, with the sides projected downward and bent inward to provide lugs or 'flanges 27 to receive a cushioning member or backing strip 28. reinforcing flange member 29 may be inserted between the projected portions 27.

The specific construction of the outer edge portions of the frame members forms no part of my present invention andis shown for pur poses of illustration only.

At the inner edges of each sash member 2O I provide an inwardly projecting flange 34 (Fig. 2) and also a. depressed groove or recess 35. y The glass G is retained in position against the flanges 34k and is preferably provided with a U-shaped cushioning member 36 which lits around the edge of the glass and forms a yielding engagement with the flanges 34 and With the inner edge walls of the members 20.

After the glass is thus inserted in the sash, locking bars 40, 41, 42 and 43 are inserted in the grooves-35 in predetermined order as will be hereinafter described. The side bars 41 and 42 are provided with short projecting lugs 45 at one end and with notches or recesses 46 providing shoulders 47 at the opposite ends. The ends of the top bar 43 are cut away on an upward curve as indicated in Fig. 12 and all of the locking bars are provided with small holes 48 near one or both ends thereof for purposes to be described.

Having described the details of construction of my improved window sash, I will now describe the method of assembling thc parts to secure the glass in the frame.

The cushioning member 36 is applied around the four sides of the glass G and the glass is then inserted in the frame rwith a portion of the cushioning member VseatedV against the inwardly projecting flange 34. The locking bars are then-inserted in the following order The bottom bar 40 Vis first slipped in the groove 35 along the bottom frame member, as indicated in Figs. 1 and 4. A side bar 41 is then Vinserted by hooking its end lug 45 over the end of the bar 40, as indicated in Fig. l, and then swinging the bar into place about the lug 45 as a pivot. The side bar 42 is then similarly inserted, as indicated in Figs. l and 2, and the top bar 43 is then placed in positionv by inserting the left hand end into the notch 46 of the bar 4l and causing it to engage the shoulder 47. The opposite end of the bar 43 engages the inner face ofthe bar 42 and forces the bar yieldingly outward as the bar 43 is pushed 'upward. If necessary, additional force maybe exerted against the bar 42 tov swing it outward to permit the upward movement of the bar 43. i

As soon as the end ofthe bar 43 passes the ing engagement with the barV 43, the bar4 42 is preferably given a slight longitudinal curve, as indicated in Fig. 9, the bar being straightened as the bar 43 is snapped into position. 1 l In Fig. 11, I have indicated a slightly modified construction in which the side bar 42a is bevelled or tapered on the rear edge at its upper end so that it may be readily forced outward when the bar 43 is inserted.

Having inserted the locking bars as above described, it will beA seen that each barV is locked by two of the other bars and that they are thus firmly retainedin position, securing the glass from accidental displacement.V

If it is desired to remove the glass, the bars may be removed in the reverse order,'first forcing the upper end of the bar 42 outward sufficiently to clear the end of the bar 43. A rod or pin may then be inserted in an adjacent hole 48 and the bar 43 may be thus drawn out of its groove 35. The bars 42, 41 and 40 may thereafter be removed by similar use of a pin inserted in holes 48.

It should be particularly noted that the insertion or removal of the glass may be performed without removingthe sash from the window casing, an item lof very substantial importance, particularly when the invention is used in connection with highly finished structures, such as a railway car.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims but what I claim is Y l. A metal window sash comprising a sash frame having grooves along its inner edges and havinginwardly projecting flanges, and locking bars seated in said grooves and effective to hold a glass in position against said flanges, said bars having locking adjustment with each other by which they are mutually retained in glass-holding position, and one of said bars being resilient to permit movement thereof out of locking position.

2. A metal window sash comprising a sash frame having grooves along its inneredges and having inwardly projecting flanges, and locking bars-seated in said grooves and effective to hold a glass in position against said flanges, certain of said bars having notched ends effective to receive the ends of other bars and preventing "inward movement thereof from glass-holding position and one of said other Abars being resilient to permit retention thereof in operative position and being yieldingly movable from its position of engagement with an adjacent notched end.

3. A metal window sash comprising a sash frame having groovesalong its inner edges and having inwardly projectingflanges, and locking bars seated in said grooves and effective to hold a glass in position against said flanges, said frame comprising recessed frame members connected at the corners and held in alignment by reinforcing corner members extending adjacent to and beyond said grooves which fit in said recesses and extend as integral units along said recesses at each side of each corner of said frame.

4. A metal window'sash comprising a sash frame having'grooves along its inner edges and having inwardly projecting flanges and lock-ing bars seated in said grooves and effective to hold a glass in position against said flange, each of said bars having Vits ends in engagement With two adjacent bars, one of said bars being resilient and shaped to permit flexing into and out of engagement with its adjacent bars.

5. A metal window sash comprising a sash izo isc

frame having grooves along its inner edges and having inwardly projecting flanges, and locking bars seated in said grooves and efi'ective to hold a glass in position against said flanges, two of said bars having notched ends efective to receive the ends of other hars, an# other of said bars having rounded ends effective to engage the notches in adjacent bars and another of said bars having squared ends adapted to fit the remaining notches in adjacent bars, said notches, rounded ends and squared ends eii'ective to form a lock and prevent inward movement of the bars from glass-holding position.

In testimony whereof I have hereunto affixed my signature. CHARLES H. TURNER.
