CASEMENT SASH FRAME.

Application filed December 26, 1925. Serial No. 77,780.

In the manufacture or sale of what is known as stock casement sash frames or those ready made for use in a building, it has been customary and in fact necessary to make two different types of frames; one

a for an inswinging casement sash and the other for an outswinging casement sash.-

This is due to the fact that the stock or standard casement sash for inswinging or outswinging are of the same dimensions and the standard frame with the dip or inclination of the sill as generally made would not accommodate a casement -sash of the same dimensions used in both the inswinging and outswinging positions, nor is the sill of an inswin ing sash adapted to receive the hardware for an outswinging one. Hence, the manufacturer has been obliged to make two styles of frames and supply them in'that way to the trade. The dealer of course never knew which type would be specified or called for by the architect or contractor and he found it necessary to carry a stock, which might not be the kind in most demand. Frequently, the dealer would find himself with a large supply of one style and an order might be received for the other style of which he had none. This method, therefore, of making and handling the frames has been not only awkward and inconvenient for the manufacturer and dealer buthas involved considerable unnecessary trouble and ex use.

he object, therefore, of our invention is constructions and combinations all as here-- inafter described and outjin the claims. In the accompanying drawings forming part of this specification,

Figure 1. is a perspective view of a sash frame showing an outswinging casemen sash;

particularly painted inswinging casement sash;

is a vertical sectional view of Figure 4 is a sectional view on the line 4+4 of Figure 2;

Figure 5 is-a sectional view on the line 5-5 of Figure 3;

Figure 6 is a perspective view of the auxiliary window sill that is used with the outswinglng casement sash and Figure 7 is a perspective view of the removable bead that is used with the storm and screen sash for both the in and outswinging casement sash.

' In the drawing, 2 represents a window sill having at its inner upper edge a rabbet 3 and a longitudinal rib A provided with a substantially flat upper surface 5. The inner face of this rib forms the vertical wall of the rabbet as indicated in Figure 2. The outer face of the rib is curved preferably at 6 andmerges into the outwardly and down wardly inclined upper surface of the sill. At a point between the rib 4 and the outer edge of the sill a shoulder 7 is formed extendlng lengthwise of the sill against which the lower rail of the storm sash is seated. We have shown in the drawing the invention applied to a mullion type of sash in which 8 represents the side jambs; 9, the head jamb; 10 the mullion' jamb between the sash; 11, the outer casing and 12, the top or head casing extending horizontally across the window.

In Figures 1 and 2, we have shown the frame equipped with outswinging casement sash 13 hinged at 14, and seated against the stop 15 at the head of the frame and overlapping the shoulder 7 at the bottom. When the sash is mounted to swing out, as described, the screen and storm sash must, of course, be mounted at the inner side of the frame, and we have shown in Figure 2, a

storm sash 16 fitting the rabbet 3 in the frame and having its .lower rail rabbete'd or recessed as indicated to receive the shoulder '4 and form a weatherproof joint therewith.

The standard dimension, however, of the in and outswinging sash is one and threeeighths inches thick and the window frame is, therefore, rabbeted to receive a sash: of this thickness. The standard dimensionof storm and screen sash is, however, one and one-eighth inches thick and provision must, therefore, be made for fitting the storm or screen sash to the rabbeted frame when put in place of the swinging casement sash. \Ve, therefore, provide a head 17 corresponding in thickness to the difference between the thickness of the easement sash and the screen and storm sash. This bead, as shown in Figure 2, is fitted snugly against the inner face of the rabbeted frame to form a seat for the screen or storm sash.

In the manufacture of the frame, the head 17 will be placed in the outer rabbet of the frame against the stop 15 as shown in Figure 3, and if an inswinging casement is to be used, the bead will exactly compensate for the difference in thickness between the storm sash and the easement sash so that the storm sash will fit in its seat perfectly and be flush with the outer edges of the side and head jambs as shown in Figure 3, the lower rail of the sash being seated against the shoulder 7. When, however, an outswinging casementv is to be used. the bead 17 will be removed and one end cut otf sulficiently to allow it to be inserted into the inner rabbet of the frame. If the inswinging casement is used, the head will be furnished as illustrated in Figure 3, all the parts being in proper position for this type of sash. In case, however, an out swing is specified, or called for, the bead 17 will be moved to the inner rabbet as described, and then in addition we provide an auxiliary sill 18 having a flat upper surface 19 which merges into, and forms, a continuation of the surface 5 of the shoulder 4, the under surface of this auxiliary sill being inclined and curved at one edge to fitthe top of the main sill and the outer face 6 of the shoulder 4. A square outer edge 20 is provided on this auxiliary sill against which the lower rail of the outwardly swinging sash is seated, thus forming a' weather-proof joint at this point and particularly this auxiliary sill provides a normal fiat sill surface for the sash frame when the inside storm sash is removed.

The auxiliary sill has also the function of forming a fiat surface on which the casement sash hardware may be mounted, it being impracticable to mount such hardware on the inclined surface of the main sill of the frame.

The rabbet in the head jamb is indicated at 9 adapted to receive the upper rail of the inswinging sash. This rabbet, or a similar one, however, is omitted at the outer edge of the head jamb, the stop 15 secured to the under side of the jamb taking its place as indicated in Figure 3, the head 17 being seated against this stop when an inswinging casement sash is used. The use of a stop in place of a rabbet compensates for the dip or inclination of the window frame sill. To illustrate, referring to Figure 2 of the drawing, the frame is shown equipped with an outswinging sash and evidently to use a sash of the same dimensions as that adapted for inswinging movement, the stop 15 must be used instead of a rabbet similar to 9 to compensate for the variation in level of the lower outer edge of the outswinging sash and the inner edge of the inswinging This difference in level is indicated by dotted horizontal lines in Figures 2 and 23. When the outswinging sash is used, then of course, no rabbet is necessary in the outer portion of the head jamb, the stop 15 providing a seat for the upper rail of the sash when used in an outswinging position. '0 regard this feature as an important one in the case as it adapts the easement sash for either an outswinging or inswinging position without the necessity of changing the length of the sash to compensate for the tilt or drop of the window sill.

Generally, in manufacturing the sash frame, the heads will be put in place by the manufacturer in the outer rabbets of the sash frame, to be removed therefrom, cut off, and then placed in the inner rabbet when an outswlng is desired, but we may prefer to furnish the auxiliary sill in comparatively long strips so that when there is call for them, the dealer may have them cut up and fitted to the sill of the frame to adapt an inswinging casement for an outswinging one.

We claim as our invention:

1. A sash frame comprising a sill and side and head jambs, the inner and outer portion of said sill and jambs being adapted respectively for mounting an inswinging or outswinging casement sash of substantially the same dimensions therein.

2. A sash frame comprising a sill, outwardly and downwardly inclined, and side and head jarubs, said head jamb having a stop on its under side and also having a rabbeted inner portion, said stop and rabbet adapting the frame to receive an outswinging or inswinging casement sash with the same height'of sash in either position.

3. A sash frame comprising a sill and side and head jambs therefor, said sill bein outwardly and downwardly inclined, an said head jamb having a stop to receive the upper rail of the outswinging sash, the distance between the under side of said head .jamb and the frame sill corresponding to the distance between the inner surface of the sill and the seat of the inswinging sash in said head jamb.

4. A sash frame comprising a sill and side and head jambs therefor, adapted to receive either an in or outswinging casement sash, and means adapted to be moved from one jamb to the other to adapt either inside or outside edge of jamb to receive a storm or 1 was screen sash of less thickness than the case ment sash.

5. A sash frame comprising a sill and side and head jambs therefor, and provided with inner and outer rabbets adapted to receive the sash of either an in or outswinging casement, and beads removably fitting in said rabbets to adapt either of them for a storm or screen sash of less thickness than the casement sash.

6. A sash frame adapted for either in or outswinging sash comprising a sill and side and head jambs therefor, and an auxiliary sill adapted to be placed between the inside storm sash and the outswinging sash when the frame is used for a sash of that type.
