WINDOW STRUCTURE. i i

Application filed April 11, 1921. 7 Serial No. 460,205.

T all whom it may concern Be it known that L'HARRY E. BRADNER, a citizen of the United States of America, residing at Fremont, Sandusky County, Ohio, have invented new and useful Window Structures, of which the following is a specification. v i This invention relates to flexibility or range of use in closures for openings in buildings.

This inventlon has utility when incorporated in swingable windows, generally referred to as the reversiblefitype. I

Referring to the drawings:

Fig. 1 is a perspective view, with parts broken away, of an embodiment of the invention in a double sash window; Fig. 2 is an enlarged section through the frame at the pivot point as to the upper sash and at the top railas to the lower sash;

Fig. 3 is-a fragmentary viewon an enlarged scale of the compound side rail as embodying a primary sash member, a weatherstrip, and a runner; c Fig. 4 is. a vertical section through the window and. frame, parts being broken away; and I Fig. 5 is a perspective view of the sash corner assembly blocks with side sash mem bers indicated to show the assembly relation.

Building or structure'l is shown as hav may be assembled the closure or window offhis'invention. To this end, a simple em bodiment may be a sheet metal installation having vertical side frames comprising structure opening seat engaging portion 3 carrying by means of bolts or engaging means 4 such number of yokes 5 as may be desirable for rigidity, according to the dimension of thewindow frame. This first seat portion 3 of the frame, carries outer. trim '6. Bolts 7-therethrough may not only stiffen the positioning of this first frame portion 3 as to the yokes 5, but also mount window seat portion 8 of this frame in as; sembled' position as to the yoke 5. Intermediate of the extent of this second seat portion 8 and 'interfitting with Uportion 9 of the yokes5, the seat portion 8 has a channel 10 in which U shaped sash spacing guide strip 11 may be removably mounted by bolts 12, after the outer sash has been mountedin the frame. Y

The completion of the side frame assembly may occur after-the inner or lower sash is assembled in the frame. To this end, the inner semi-beaded terminus 13 of the first seat portion '3, nesting inyoke seat 14, may be engaged by semi-beadededge 15' of interior finish section 16v of the side frame, and on such interfitting bead portions as a hinge be swung into position against the window seat providing portion 8, andlthere detachably anchored. by bolts 17 which not only engage the yoke 5, but further stiffen the seat portion 8,-by passing therethrough and holding the portion 16 .ofthe inner fin ish thereagainst. The side frame assembly is thus complete and of acharacter for ready access, such as mounting of counterweights 18 on cordsv 19 extending over sash cord guides. 20 to be connected to the sash.

At the top, the side frame members may be connected by a boxshaped or hollow structure comprising outer frame -member and trim 21 with inner finish member or portion 22 mountedthereon by bolts 23.

A ledge 24 of hollow sheet metal structure is shown with a groove 25 adjacent the inner side. of the sash seating portionof the ledge. In this groove 25 may engage a downwardly projecting rib or flange 26 .of

"In this frame, there is shown as mounted two singlelight sash. Upper light 31 has top rail 32, bottom rail 33, andside members 34 as itsframe. The light holding side members 34' are a part of compoundgside rails. The side members 34, on the side thereof opposite the light 31 have a pair of seat portions 35 throughout the length o-f the member 34, bounding an intermediate channel 36.1 A second side rail member 37 has a channel 38 opposing the channel 36. This channel 38 has on each side. thereof seat por tions 39 resting for close fitting with the seat portions 35 of the member 3a. The two members 34, 37, of the compound side rail thus may have a substantial assembly relation. his member 37, on its side remote from the channel 38 has an opening to its hollow interior.- This permits convenient assembly of nuts ll upon pivot pins 42 anchored in the side rail members 34; and protruding through the channels 36, 38, to anchor a weather-strip as in the member or runner 37 of the side rail. This half oval weather strip 43 sealing the joint between the compound side rail members 34;, 37, also serves as a catch or lock normally holding the primary sash member 37 of this compound side rail against swinging. To this end this weather-strip means 43 is normally urged from the channel 38 to seat in the.

channel-36, by leaf spring 44 about the pivot pin 42, while the remote portions may be similarly urged into the channel 36 by helical springs 45 about guide pins 46 in the channel 38. These springs thus afford a yieldable resistance against any shifting of the light 31 and its frame 32, 33, 34, 3e, upon the pair of pins 42 as pivot bearings. Pressure upon this sash exerted suificiently to depress the Weatherstrip as out of the channel 36 and force it b-acli into the channel 38, as the seat portions 35, 39, move out of longitudinal register and the reversible window swings open, does not leave this strip 4:3 in active. The springs 44, 45, cause this strip to be held up so snugly against the seat porions 35, that the window is thus held in whatever rocked position it may be left.

Whenever the window is brought back tovertical position to have the compound side rails in alignment, at. once, the weathers-trips 43, snap into window assembly holding relation, and this special window is held against swinging movement. 7

The lower window section having light 4-7, has a frame for this light in the form of a hollow sheet metal sash having top rail 48, bottom rail a9, and side members 50. These side members 50 correspondto the side members 34: of the upper sash, and are completed as a compound side rail by runner members 37 and weather strips 4L3.

In the building up of these hollow sheet metal sash, connector blocks are provided. In the top rail 32 of the upper sash, a block 51 may be anchored by swaging, riveting or bolting, to provide a seat to which side member 37 may be connected. The lower end of the side member 36 may seat against con.- nector block 52 mounted in bottom rail 33 of the upper sash. The top rail 48 of the lower sash has connector block 53 anchored therein, say by bolts 54:, while the side member 50 is bolted thereto by bolts The bottom rail 49 of this lower sash affords seat for connector block 56 to be nested with the side member 50 in the sash assembly.

The elements of the compound side rails, while hollow or of tubular form, are terminally closed.

The sheet metal type of installation as herein disclosed, may be of light weight, readily susceptible of quantity production for regular installation complete as window and frame. The readily shiftable or removable inner finish section 16 of the side frame has advantages of accessibility to the frame interior, desirable in mounting and adjusting counterweights. The runner and weather-strip features of the compound side rails, while herein shown as a part of a specially constructed compound side rail, it is to be noted may be readily adapted to a general type of wooden side rail, by merely cutting down such side rail to provide a pivot pin mounting the channel and the seating portions therealong, while the runner, which may in such instances be of wood if desired, is configured as to opposing seat portions and intermediate weather strip channel. Thus, without disfiguring or modifying the window frame and slide portions, the runners of this disclosure for swingably carrying a sash, may be incorporated in existing installations, giving the features of this disclosure a wide field of use.

What is claimed and it is desired to secure by Letters Patent is:

1. A compound side rail for sash including a primary sash member of closed figure cross-section and provided with a weather strip receiving channel, a hollow cross rail, a corner block fitting into the cross rail terminating therewith and contoured to seat against inner side of the sash member as extending over the end of the cross rail and means for anchoring the block to said member and rail.

2. A window embodying a pair of sash, runners to which the sash are pivoted for rocking, weather strip means between the runners and sash automatically frictionally holding the sash in closed position as to the runners, a window frame unit to be engaged by the runners, counterweights for the run ners housed by said unit, a trim closure for a side of the unit hinged to permit access to the counterweights, and means for anchoring the trim in closed position adjacent the runners to confine the runners for straight line travel as coacting with the counter weights, said trim permitting clearance for sash rocking against the resistance of said weather strip means.

3. A. window embodying a pair of sash, a frame mounting one sash above the other in window closed position, said sash having side members in pairs one beyond the other, said side members being grooved longitudinally on the outer sides thereof, runners in the frame opposing each of said side members, said runners medially of their extent having pivot pin connection with the side members normally positioning the runners and side members in abutting relation, a Weather strip housed by each runner and through Which Weather strips the pivot pins extend, and springs normally thrusting the weather strips into the sash member grooves between the portions of the members as abutted by the runners.

4. A Window sash having parallel side members, longitudinally extending oppositely outwardly open grooves in said side members, each bordered by a pair of faces pivotpins extending from the longitudinal central portions of said grooves, runners abutting the members on the pairs of faces of the members on opposite sides of the grooves and mounted by said pivot pins, said runners having channelsopposing the sash member grooves, Weather strips in the run ner channels between the members and runner abutting portions and mounted by the pivot pins, and springs in the runners coacting for maintaining the weather strips thrust towards the sash members.
