HENRY VJ. LANDOLT, OF BROOKLYN, YORK.

WINDOW-SASH CONSTRUCTION.

Specification of Letters Ifatent.

Patented Sept. 1, 1914.

Application filed March 6, 1913. Serial No. 752,447.

To all 'w/wqnit may POW/(6TH Be it known that I, HENRY W LANDOL'l, residing at Brooklyn, in the county of Kings and State of New hork, have invented certain new and useful Improvements in lViiidow-Sash Construction, of which thefollowing is a specification.

This invention relates to window sash coir struction, and the particularobject thereof is. to provide a simple design therefor, whereby a sash of eXceptional strength may be manufactured at comparatively small cost. i

A further objectis to provide a structure formed of parts so shaped and arranged as to be capable of easy asse i'iblage, and to adapt said parts so that, when assembled, they will interlock with each other in sul stantially immo able relation, whereby each will lend its strength to the other in with standing strains to which the sashmay be subjected. v

A. further, and somewhat more detailed object, is to provide intersecting base or body members forming a lattice, and to provide separately formed molding pieces for positively locking the base members together. I H

Other objects and ainis'of the invention, more or less specific than those referred to above, will. bein part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown a merely pre ferred form of embodiment of the invention: Figure 1 is a detail perspective view of a portion of a window sash constructed in accordance with the provisions of this invention, the marginal frame of said sash heing illustrated in dotted lines, and parts ofthe lattice work of said sash being illustrated in fully assembled relation, and other parts being illustrated in process of assembling; and Fig. 2 is an enlarged detail sectional section being taken on the plane of line 2-2 1, looking in the direction of the Referring to the drawings for. a detailed description of the parts and their method of assembling, the reference nun'ieral 1 ndil l l 4 I catcs a plurality of vertically disposed lattice pieces, which will be hereinafter referred to as the vertical base members.

They extend from top to bottom the -martice pieces extending transversely 'of the base members 1 preferably from side to side of the sash frame, and being capable 'of'attachment to said side pieces in any suitable manner. These will be hereinafter referred to as the horizontal base member s, andmay also be in any number according the height of the sash and according to the height of the glass section to be disposed between them. The base members '1 and 8 therefore are adapted to define a plurality of rectangular areas within the marginal frame 2 of the sash, each of said areas he closed or filled with rectangular pieces of glass l, as will be understood. i

The base members 1 and 3 are preferably of substantially identical cross section, each comprisinga web portion 5 and a head portion 6 extending longitudinally at one edge of the web and forming therewith a T-bar.

T 1e opposite longitudinal edges 7 of the head portion 6 of each of the pieces 1 and 3 are inclined relatively to each other, as best seen in Fig. 2, from the'outer surface of the head inwardly toward the web 5 for a purpose presently to be described. These base members intersect eacliother, and at the sevi v e i i p eral points of intersection they are provided with cut out portions or slots 8 and 9 respectively, so that the pieces may be nested together in a Well-knownmannerl It is material which of the sets of base members are provided with the slots extending through the head portion thereof, biitfdr the purpose of illustration the'inembers 3, extending from side to side of the sash are provided with such slots. With thisunderstanding several of the members 3 may have their slots 9 engagedwith one only of the members 1, the single member 1 serving to hold the several members 3 in spaced relation, this being done before anyof the n em bers are inserted within the frame 2.

jlrinolding piece 1,0, having dove-tailed slot 11 extending longitudinally in its under surface, is attached to the base member 1 by telescoping the head portion 6 of the member 1 within the dove-tailed groove 11 of the molding, the opposite inclined edges 7 of the head serving to positively retain the molding against detachment laterally from the head. This molding piece 10 is of continuous cross section being preferably entirely devoid of any notches or cut-away parts whatever so as to attain maximum strength. 1

In the case of the first base member 1 to be assembled, the molding 10 may be attachedto the base before the said base is assembled with the horizontal base members, but it may be here noted that in assembling subsequent base members 1, this is not the case, as Will. be presently apparent.

Molding pieces 1.2, slmilar to the piece 10, except-as to length, are applied to the head portions 6 of base members 3, the dovetailed grooves of said. molding pieces 12 engaging with the inclined sides of the head portions 6 of base members in the same manner as does the molding 10 with the head portion of the base member 1, above referred to. V

The molding pieces 12 are cut to a length commensurate with the space desired between the vertical members of the lattice, that is, with the slots 9 formed in the base members 3, and the opposite ends of the molding pieces 12 are coped away so as to form relatively overhanging parts 18 shaped to fit closely about shoulder portions 1 1 formed on the relatively outer surface of the molding piece 10 as best seen in Fig. 2. The molding pieces 12 are telescoped longi tudinally over the head portion 6 of the base members 3 from opposite directions until the ends 13 thereof engage closely over the shoulder portions 1 1 of the molding 10.

lVith the structure thus far assembled, a.

second vertical base member 1 may be inserted, or nested, Within the next row of slots 9 of the base members 3. Such a base member 1 is illustrated at the right of Fig. 1 in position to be engaged in the slots 9 of the base pieces 3 after the lower molding piece 12 has been moved to the left to uncover the slot 9 in the lower base member 3.

tively and rigidly lock the base member 1- to each of the base members 8 of the structure. The lock is further strengthened by 1 be assembled.

the placing of other molding pieces 12 at the opposite, or right hand, side of the'molding 10 just placed.

Each subsequent vertical base member 1 must be attached in the same manner as that just described, and molding sections 12 applied to the base members 3 before the next succeeding vertlcal base member 1 may The moldings 10 and 12 are easilv applied by telescoping over the heads of the base members, and are as easily detached there from in the same manner, no tools being required for either operation. I When the full lattice portion of the sash is thus assembled, it is inserted within the marginal frame 2 which may have been already constructed, or which may be built about the lattice and attached thereto in any desiredmanner, the details of which attachment are not important to the features of this invention, the only essential of the frame being to lend added strengthto the lattice and provide shoulder portions as at 15 for preventing longitudinal detachment of the outer molding pieces 12 and also of the molding pieces 10.

It may be here noted that, in the completed lattice, each'of the molding pieces 12 is positively held against longitudinal movement by theengagement of its opposite ends with thesides of the moldings 10 so that both the moldings 10, and their base members 1, are held by each molding piece 12, and it is practically impossible to disassemble the lattice exceptby telescoping the moldings 10 longitudinally off of the base members 1. This may however be done whenever desired since the moldings are all readily detachable.

The head porti is cut out for a short distance at opposite sides of the slots 9 as at 18 for accommodating the over-hanging portions of the moldings 10, forming a sort of groove through Which the moldings 10 may slide. The overhanging portions 13 of the moldings 12 also provide a sort of groove through Which the molding 10 may slide. I

The web portions 5 of the base members 1 and 3 define the rectangular areas within which the glass sections 41 are confined, and. the under surface portions 16 of the moldings 10 and 12 provide a shoulder extending around. said areas against which the inner surface of the glass sections rest. Retaining members 17 for the glass sections are .at-{ tached to the web portions 5 and engage the outer surface of the glass to hold it against detachment. These retaining pieces may be formed of any material, but preferably comprise angle sections arranged with one leg resting against the Web 4: and with the other leg resting against the surface of the glass, the first mentioned leg being connected to on 6 of the cross pieces 3 the web by a screw or other device 19 which may obviously extend throughthe web and serve as the retaining means for a similar glass holding element at the opposite side of theweb, or not, as desired.

The continuous uninterrupted formation of the molding pieces 10, it will be noted, add very materially to the strength of the vertical base members 1. These base members being formed with notches Sin their web portions spaced from. theheadthereoit' are considerably weakened, and the continuous integral formation of the molding attachedfto the headwill in a great measure compensate for the loss occasioned by the presence'oii the slots 8. The moldingsl0,by their intimate engagement with the molding pieces 1.2, will transmit their strength through said molding pieces 12 to the base members 3. The notches in the base members 3, being formed through the head portion thereof, leaves a portion of the web only to resist lateral strains, but the interlocking relation of the ends of the molding f-lll pieces 12 with the moldings 10 will fully compensate for the loss sustained in the cutting away of the head portion.

Forces tending to bow out the window from the .inside, that is, from the side to which the moldings are attached, will be resisted by the vertical pieces 1, which, with the continuous molding pieces 10 fixed thereto, will effectually resist such strains, the molding being relatively under compression longitudinally, and the outer longitudinal edge of the web portion 4t being relatively under tension. The strength of the struc ture in resisting forces from within is materially increased by the base members 3 where the moldings 12 will also be relatively under compression, and the outer longitudinal edges of the web portions of the base member being relatively under tension. The sides of the apertures 9 will grip against the opposite side surfaces of the web 5 of the base members 1, and this in effect, will complete the web of the members 3 to their full cross section. The ends of the molding pieces-12 will wedge against the opposite sides of the moldings l and this also will, in effect, completethe moldings 12.

Forces tending to bow the structure in aardly will be opposed principally by the vertical base members 1, which, it will be noted, are fully capable of withstanding a very considerable pressure from Withoutfor the reason that they will. present to such forces substantially their full cross section unimpaired continuously of their length, the sides of the notches 8 gripping against the opposite surfaces of the webs of the base members 3. The connecting portions at the notches 9 of the base members 3 will also serve to resist forces from without.

The interlockingengagement of all of the parts will, of: course, serve to resist forces both from within and from without.

It is thus seen that I have provided a structure of simple parts, easily and cheaply manufactured, and capable of being assembled into an exceptionally rigid lattice by 'matter contained in the above description or shown in the accompanying drawing v intersecting base members, and molding pieces detachably carried by said base members and serving to lock said base members together.
