15 Claims.

This invention relates to closure constructions, and has for an object the provision of a closure construction which represents an improvement over that disclosed in my allowed application Serial No. 314,706, filed October 24, 1928, issued April 7, 1931 as Patent 1,799,719.

The closure construction of my aforesaid application comprises a hinged closure, such as a sash, and a hinged screen so disposed with relation to a window orother opening that the screen is toward the inside with respect to the closure, permitting the closure to open outwards from its casement without having to leave the screen also in open position.

The present invention contemplates the adaptation of substantially the same principle to metal sash and casement constructions, it being understood that the device of the allowed application has been applied specifically to other constructions.

A more detailed object is to provide a closure construction in the form of a casement having a closure, such as a'conventional steel frame sash hinged thereupon upon adjustable hinges, permitting the insertion of a screen frame or an auxiliary sash frame between the casement and the first mentioned sash frame, both frames being mounted for pivotal movement about a common axis in being swung to and from closed position.

Another object is to provide an auxiliary frame as described, which is receivable between the main sash frame and the casement, and which is adapted to maintain a. plurality of lines of engagement of the closure with the casement, these lines substantially encircling the opening of the casement so as to provide a multiple seal when the closure is in closed position.

A further object is to provide a novel hinge construction, whereby the adjustment of the main closure necessary for the insertion of the auxiliary frame, is made possible.

A still further object is to provide novel means for mounting the screen or auxiliary frame upon the same hinges as those upon which the main closure frame is mounted, this mounting means permitting facile removal and replacement of the screen or auxiliary frame whenever desired, thus facilitating the operation of washing the pane or panes of glass in the closure frame.

The invention possesses other objects and advantageous features, some of which, with those enumerated, will be set forth in the following description of the inventions particular embodiments which are illustrated in the drawings ac- 1931, Serial No. 525,534

The conventional construction of steel window casements and sash frames is such that a double weather seal encircling the opening of the casement is established when the sash frame is moved to closed position, inasmuch as the sash frame makes engagement with the casement in a double line of contact encircling the opening. The present invention contemplates the provision of a novel construction whereby an auxiliary frame, such as a screen frame or the frame of a stormsash, may be added without destroying this double seal. The auxiliary frame, furthermore, is disposed upon the inside with respect to the window construction, thereby permitting the main frame to be left open, without requiring that the auxiliary frame also be left open, as is the case in conventional screened closure constructions where the screen is hung exteriorly with respect to the closure.

The preferred embodiment of my invention has been illustrated as being cooperatively associated with a steel window casement 11, which comprises a substantially Z-shaped strip 12 substantially encircling the window opening 13. Inasmuch as the casement illustrated is double, i. e. is provided with twowindowopenings 13,, the central stile 14 of the easement 11 is common to both openings 13, and therefore, instead of being Z-shaped in cross sectional configuration, is substantially T or L their respective planessubstantially coincides with the distance; between the planes of the base flange 16 and the bead 17; of the casement 1-1. The

present invention contemplates the provision of hinges 27 for'the' closure frame 21,,of such a nature that they may be, adjusted subsequent to installation, thereby permitting mounting the screen or storm sash at any time that may be desired after completion of: the'building in which the casement 11- isgmounted These hinges 27', however, are of, such a. nature that. when the screen or storm sash frame is not present the closure.- frame when closed establishes a double storm proof seal with the easement 11. This isaccomplished asa result of the fact that the base flange 24, of the closure frame 21. engages the base flange 116 of the casement 11- at the same time that engagement takes: place between the outer flange 26 of the closure frame 21 and: the outer surface of the bead 117' which extends outwards with re:-

Tspect to the base flange 16.

The closure frame; 21. is: illustrated as being provided with a pane 2,8 of, glass, with the-result that light may be-admitted through the associated opening-1'3 when theframe 21 isswungclosed, but

' aircurrents excluded.

The auxiliary frame 31 is preferably in the form of a channel 32- opening outwardswithin, which a smaller channel 33. isreceivable, the outside width of the smaller channel 33, beinggsufliciently smallerthan: the; insidewidth of the channel 32'to permit 31 is, in the presentv modification,v designed as a screen frame, it is entirely within the scope of the present invention to substitute a second pane of glass or other suitable material for the screen 36, under which circumstances the auxiliary frame 31 would support a storm sash instead Ifof a screen.

The outer edge of the channel 32 of the auxiliary frame 31 is continued in the form-of a substantially Z-shaped' flange 38, the base 39 of which is adapted to be received between the base -Tflange 16 of the casement. 121; and. the flange 24 It should.

of the closure frame 21, and the outer flange 41 of which is adapted to be received between the outer flange 26 of the frame 21 and the bead 17 of the casement 11. Hence, the imposition of the screen frame 31 between the closure frame 21 and the casement 11 necessitates adjustment of the closure frame 21 in such a manner that it is moved outwards a. distance substantially equal to the thickness of the extension 38 of the channel 32. The hinges 27, by means of which the closure frame 21 is mounted, are provided with means for effecting this adjustment.

Each of these hinges 27 comprises a casement leaf 42 secured to the outer face of the casement 1 1 and extending outwards preferably angularly with respect thereto. The pintle pins 43, which are rigid with the outer ends of these leaves 42, are in axial alinement, permitting the leaves. 44 which are secured to the sash frame 21 to be mounted thereupon for pivotal movement, whereby the sash frame 21 can optionally bemoved-:toopen or closed position with respect to the casement 11. Instead of being journaled accurately upon the pins 43, however, the sash leaves 44 are provided with substantially ovalshaped holes 46 materially larger than the cross sectional area of the pintle pins 43, and within each of these-holes 46a complementarily shaped bushing 47 is received. Each. bushing is provided' with a. hole 43, within which one of the pintle pins 43- fits accurately, but instead of being midway between the ends of the major axis of the associated oval-shaped bushing 47 the hole 48 is nearer one end than the other of the bushing; Moreover, the major axis of the hole 46 in each of the sash leaves 44 extends substantially perpendicularly with respect tothe plane of the sash, with the: result that by reversing the bushings 47 within the holes 46 in their respective leaves 44 the effective length of those leaves may be varied. Thus, it may be seen that if" the closure constructionv is installed, without the auxiliary frame 31, the bushings 47 should be turned so that theholes 48 therein are adjacent their outer ends, thereby increasing: the effective length of the sash leaves 44 and causing the sash frame 21 to establish the doule' weather seal, with the casement 11,- as hereinabove; described. However, when it is desired to mount the auxiliary frame 31, the bushings 47. should be reversed, positioning. the holes 48 adjacent their inner ends, thus decreasing the effective length of the leaves 44 and: spacing the sash: frame 21, when closed, outwards from the casement, 1.1 a, distance equal to twice the eccentricity of the holes. 48 with respect to the center of thema-jor axes of their respective bushings 4.7.

The auxiliary frame 31 associated with each of the window openings 13 is mounted for pivotal movement about the same axis as that about which the associated closure frame 21 is mounted. This is accomplished by means of the extended. pintle pins 43, permitting each of. the pintle pins 43" to pivotally receive a leaf 51 connected to the'associated auxiliary frame 31. Instead of being rigidly attached to the auxiliary frame 31, however, the hinge leaves 51 carried by each. pair of alined pintle pins 43' is connected to a standard or bracket 52 which is disposed vertically within the space 53 between the webs 18 and. 23 of the casement 11 and the closure frame 21- at the hinged side of the closure frame. Means are provided for removably mounting the auxiliary frame 31 upon the vertically extending portion54. of the bracket 52. Preferably, this is accomplished by means of a plurality of pins 56 which extend from a face of the vertical portion 54, each pin having a head 5'7. The flange 38 is provided with a similar number of vertically elongated holes, each of which is of keyhole shape, inasmuch as the lower end is large enough to receive the head 5'7 of one of the pins 56 therethrough, whereas the upper end of the hole is slightly larger than the shank of the pin 56 but smaller than the head 57. This permits the auxiliary frame 31 to be mounted upon the bracket 52 by engaging the holes in its flange 38 upon the pins 56 of the associatedbracket 52, with the frame 31 in slightly elevated position, and then' permitting the frame 31 to drop until the pins 56 are seated within the upper smaller ends of the 'holes, the parts being so proportioned and arranged that when the frame 31 drops in this manher it comes accurately into proper position with respect to the easement 11 and closure frame 21. Each of the leaves 51 is in reality a.

lateral extension of the vertical portion 54 of the associated bracket 52. However, inasmuch as the conventional arrangement of hinges whereon metal sash are mounted positions the pintle pins 43 extending toward each other from their associated hinge leaves, one of the arms 51 is made up of two sections 58 and 59, releasably united by means of a plurality of screws 61 or their equivalent. This permits mounting the bracket 52 for pivotal movement upon the same hinges as those upon which the closure frame 21 is mounted, by disassembling the two-piece arm or hinge leaf 51, seating the eyes 62 which are provided at the outer ends of the arms 51 upon their respective pintle pins 43, and then reassembling the sections 58 and 59 of the arm 51.

In order to accommodate the arms 51 of each bracket 52, the flange 26 of the closure frame 21 is provided with a slot 63 in the hinged edge of the frame 21 in position to permit each arm 51 to extend therethrough into the vertical space 53. The outermost flange 41 of the Z-shaped strip or flange 88 of the auxiliary frame 31 is also provided with a slot in registry with each of the slots 63 for the reception of the'associated arm 51.

Figs. 6, Tand 8 shows a slightly modified form of hinge construction, whereby the same adjustment of the closure frame 21 may be attained. The pintle pin 66 extends through a closely fitting hole 6'7 in-the casement leaf 68, and preferably a washer 69 of friction material is interposed between the head '71 of the pin 66 and the leaf 68. Another washer '72 of friction material is interposed between the uppersurface of the casement leaf 68 and the lower surface of the closure frame leaf '73. An elongated hole '74 is provided in the leaf '73, through which the pin 66 extends, and means are provided for retaining the pin 66 in the outer end of the elongated hole '74, this means being in the form of a metal washer '76 having lugs or cars '77 which are bent down in engagement with the side edges of the leaf '73 to insure turning of the washer '76 with the leaf '73.

Another lug'78 is provided upon that edge of the washer '76 which is remote from the window structure, and by bending this lug '78 downwards across the outer end of the leaf '73 when the leaf '73 '1 has been pulled inwards so as to dispose the pin 66 in the outer end of the hole as illustrated upon Fig. 9, the pin 66 may be retained in this end of the hole. This is the position occupied by the leaf '73 and the lug '78 when the auxiliary frame 31 is not mounted upon the window construction,

inasmuch as this arrangement of the parts will result in holding the closure frame 21 rigidly against the easement 11, so as to establish the double weather seal encircling the associated opening 13. When it is desired to mount the auxiliary frame 31, the lug '78 may be bent upwards, whereupon the closure frame 21 may be moved out wards a distance equal to the elongation of the hole '74, thus permitting the reception of the flanges 39' and 110f the auxiliary frame 31 be tween the casement 11 and the closure frame 21.

Another washer '79 of friction material encircles the pin 66 above the metal washer '76, and a nut 81 is threaded onto the pin 66 above the washer '79, so as to cause the parts to press against the friction washers with sufficient pressure to establish the desired amount of friction, whereby the closure frame 21 will be retained in adjusted position against the action of wind, and the like. a

' Another washer 82 of friction material encircles the extended portion 83 of the pin 66 above the nut 81, and the leaf 84, which is connected to the auxiliary frame 31, is removably receivable upon the extension 83 of the pin 66, as clearly shown upon Figs. 6, '7 and 8.

Any suitable latch means may be provided for releasably securing the closure frame 21 and/or the auxiliary frame 31 in closed position. Preferably, this latch construction, which is indicated in its entirety at 86, is of the type disclosed in my aforesaid copending application, and comprises a shank 8'7 pivotally mounted upon the screen frame 31, and carries a pair of engaging detents 88 and 89, The former of these detents, 88, is adapted to be received within a slot 91 in the stile 14 which separates the two window openings 13, whereas the second detent 89 is adapted to engage an ear 92 which is rigid with the closure frame 21, thereby locking the screen frame 31 and close frame 21 together. The inner end of the shank 8'7 is provided with a handle 93, whereby the latch 86 may be operated.

It is to be understood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope of the ap pended claims.
