Jully 1935 J. v. 1DEsMARA|s WINDOW CONSTRUCTION Filed May 23 1954 2 Sheet 1 Patented July 9, 1935 UNITED STATES,

PATENT OFFICE This invention relates to a windowconstruction and involves certain improvements over the construction disclosed in my prior Patent No. 1,893,763, dated January 10, 1933.

to provide a construction similar to that of my prior patent but in which the side rails of the lower or inner sash andthe front or inner bead of the window frame are provided with cooperating inclined surfaces which serve to maintain a tight joint betweenthe bead and iframeregardless of the shrinking or swelling of the-parts and which also prevent lateral movementand rattling of the sashin the frame.

A further object is to provide an arrangement similar to that of my prior patent in which a storm sash or extra sash can be inserted in the frame below the outer sash, such storm sash being removable and replaceable from the inside of the window and being so constructed that it can be arranged in an inclined position to form a ventilator for the window.

A still further object is to provide improved means for holding the front or inner beads on the window frame and which permit the beads to be easily and quickly detached therefrom to permit the lower sash and the storm sash to be removed inwardly from thewindow frame.

These and other. objects are attainedby the specific embodiment of my improved construction illustrated in the accompanying drawings and described in the following specification.

In said drawings: i

Figure 6 is a transverse section on the line YY of Figure 1;

Figure '7 is a perspective view partly broken away showing the construction of the movable strips arranged in the window frame, one on each side of the outer window sash;

Figure 8 is a fragmentary perspective view of the upper end of the front or inner bead which I employ; and a Figure 9 is a section on the line 99 of Figure 3.

Referring in detail to the various features of .One of the objects of the present invention is my construction, the window frame comprises vertical side members H] which may be formed of plain strips. or boards of uniform thickness.

A sill H is secured between the lower ends of the side members, In and a top member I2 is secured to the, upper ends of said side members. A facing or finishing strip [3 is secured to the inner edge of the side members l0 and similar strips l4 may be secured to the rear edges of such members. i

Adjacent the rear: edge of reach of the frame members It] and suitably secured to the inner face thereof is a rear head it, these beads extending from the top to the bottom of the window frame.

The outer or upper sash of the window is arranged in front of the beads I5, and this sash includes side "rails [6, an upper rail I1 and a: lower rail l8. Betweeneach of the side rails I6 of the upper sash andthe adjacent side members In of the window framegIarrange a strip 20. These strips extend-from the; bottom to the top of the frame and'as. they are held in position by the upper andlower: sashes, it is unnecessary to attach the same -to:the window frame as such strips are intended to be free to move laterally against the rear beads 15. If desired, the strips 20 may be loosely secured to the window frame by means of .a-slot and screw connection such as illustrated in my prior patent, which arrangementpermits limited lateral movement of said strips. As above noted, the upper sash is arranged between the strips 26 on oppositesides of the frame.

The lower or inner sash of the window includes side rails 2!, an, upper rail22, and a lower rail 23. i The side rails 2| of the inner or lower sash are arranged to abut against the strips 2&3 heretofore described. :In other words, the inner or lower sash is Wider than the outer or upper sash to the, extent; of the thickness of the strips 29.

One of the features of my present improvements involves theuse-of a storm sash positioned belowthe upper sash andoutwardly of .the lower sash. This storm sash includes a top rail 25, a bottom railv2li and side rails 25, which side rails abut-against the rear beads l5 of the frame. The storm sashlike the upper sash is positioned between the side strips 2!] heretofore described. To maintain the storm sash in position when the innersash is in its lowermost position, a lug or projection 21 is secured to each side rail 24 and these lugs or. projections are adapted to contact with the side rails 21 of the lower sash. By this construction; when the lower sash is pressed rearwardly as laterdescribed, the storm sash as well asthe'side strips 2!]- andthe upper sash of the window will be forced rearwardly against the rear beads I5. The meeting rails l8 and 22 of the upper and lower sash are so shaped and notched as to provide a tight joint and the same is true of the meeting rails i8 and 25 of the upper sash and storm sash. The joint between the lower rail of the upper sash and the upper rail of the storm sash is such as to permit the storm sash to be tilted forwardly when the inner sash is raised or removed as shown in Figure 4 of the drawings.

The inner edge of each of the strips 20 is provided with a bead 20a which extends substantially from the top of the strip to the lower rail I8 of the outer sash and this sash is arranged to slide between said beads 20a and the rear beads Hi.

The upper ends of the strips 20 form tongues 28b which are adapted to be inserted behind a transverse head 28 on the frame, which bead acts as a stop to limit the forward movement of the strips 26.

As previously noted, an important feature of my improved construction lies in the front head 30 and in its combination with other features. This bead is made up of a front or relatively fixed part 30a which is adapted to be rigidly secured to the frame members It] and a rear part 30b slidably supported in a rabbet in the under surface of I the front part 30a, preferably by means of a series of pins 390 passing through the part 3012 and into the part 30a. Arranged between the parts 30a and 3012 are several flat springs 30d which tend to force the part 301) rearwardly, or against the side rails of the inner sash when the beads and the sash are in position in the window frame.

It will be noted that the springs 30d are somewhat wider than the parts 30b so that the inner edges of said springs project into a longitudinal groove 30c formed in the part 30a and extending laterally of the rabbet in the part 30a of the bead. This arrangement forms a shoulder to engage the springs by which means the outward movement of the part 30b is limited. The springs 30d and the pins 300 thus serve to hold the parts of the beads 39 in assembled relation when they are removed from the window frame.

The outer edge of the parts 301) of each head 3% is beveled or inclined as shown at 30 and the r side rails 2| of the inner sash are correspondingly beveled on their inner corners adjacent the window frame as shown at 2 la. The springs 30d normally force the parts 30b toward the rails 2| and the surfaces 30) thus fit against and cooperate with the beveled surfaces 2la on the rails. By reason of the cooperating beveled surfaces 30] and 2m it will be seen that the inner sash will be firmly but yieldably held against lateral movement in the window frame so that rattling of the window sash is prevented, but at the same time a close fit between the bead and the sash is maintained at all times regardless of the shrinking or swelling of the sash, and all danger of the sticking of the sash in the frame is obviated.

To hold the beads 30 in position at their upper ends, each is cut away to provide an inclined portion and a tongue which cooperate with a transverse bead 32 as fully described in my prior patent. In addition each bead 30 on its inner surface is provided with one or more inclined lugs or pins 33 which engage correspondingly inclined holes in the side members I ll of the frame. These pins 33 are inclined inwardly or away from the lower sash so that they act in the nature of hooks to secure the beads in place. The outwardly inclined surfaces 30f on the beads combined with against the beads 30.

the inwardly inclined pins 33 produce a wedge ef feet on the beads so that they are firmly held in place against accidental displacement especially when the inner sash is down. By raising this sash the beads can be easily sprung or forced inwardly a sufficient extent to detach them from the frame when secured.

. It is sometimes desirable to use the storm sash as a ventilator for the window. This can be done with my improved construction. When the inner sash of the window is raised, the upper end of the storm sash can be tilted inwardly to the position shown in Figure 4, in which position it rests To permit such inward tilting, the upper portion of each side rail 24 of the storm sash is cut away as indicated at 34, the bottom of said cut away portions being inclined so as to rest against the outer edges of the beads 30 when the storm sash is thus tilted inwardly. The beads 30 thus serve to hold the storm sash in position to act as a ventilator. When complete removal of the storm sash is desired, one or both of the beads 30 are removed and the sash can then be withdrawn inwardly.

From the foregoing the construction and operation of my improved structure will be apparent and changes may, of course, be made in the details thereof. For example, a screen sash formed like the storm sash may be used and either metal or wood may be employed in my construction.

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

' 1. A window construction comprising, in combination, a window frame, an upper or outer sash in said frame, an inner or lower sash vertically movable in said frame, and a storm sash arranged in said frame below said upper sash and outside of said inner sash, and cooperating means on said storm sash and said inner sash for holding said storm sash in position when the inner sash is down.

2. A window construction comprising, in combination,a window frame, an upper or outer sash in said frame, an inner or lower sash vertically movable in said frame, a storm sash arranged in said frame below said upper sash and rearwardly of said inner sash, and cooperating means on said lower sash and said storm sash for holding the latter in position when the lower sash is down, said storm sash being free to tilt inwardly when the inner sash is raised.

3. A construction as specified in claim 2 having means on said frame for yieldingly pressing said lower sash toward said storm sash.

4. A window construction comprising, in combination, a window frame, an upper or outer sash in said frame, an inner or lower sash vertically movable in said frame, a. bead secured to said frame on each side of said lower sash and inwardly thereof, for holding the same in position, a storm sash arranged in said frame below said upper sash and rearwardly of said lower sash, said storm sash being tiltable inwardly when said inner sash is raised, said storm sash having the side rails thereof cut away to provide shoulders for resting against said heads when the same is tilted inwardly, whereby the storm sash is held in an inclined position to form a ventilator for the window.
