SASH, noon, on STORE-FRONT .oonsrrwo'rron.

Application filed February 23, 1928 Serial No. 256,433.

The present invention relates to sash, door,

or store front construction and embodies novel features, constructions, and comb nations differing from'the disclosures of my Patent 1,550,430, August 18, 1925, and pendany thickness without danger of breakage of g the pane and with adaptabilityfor ready assembly, cutting to the proper length, and durability and. firmness of grip and, further, for installation without requiring ambs or steps and, also, if used as the frame for a door, without necessitating the employment of a slam strip.

In my Patent 1,550,430 I have disclosed front and rear sections or mouldings fulcrumed on each other and adapted to be relatively tensioned but in that construction the outer moulding or section must be dropped in between the pane and the upwardly extending front part of the rear section beforethe front section, can be tensioned to grip the pane; furthermore, in my patented constructi on aforesaid, the manner in which the outer section is fulcrumed on therear or inner section, provides a joint which, under some circumstances, might collect water due to the elements and used in washing the pane with possibility of freezing, and in the pat- 0 ented construction some little difiiculty has been experiencedin' finding the screw holes in the outer section because they lie back of the upwardly extending front part of the rear section.

While the present invention is not intended I to be strictly limited to embodiments in relatively heavy extruded inner and outersections, nevertheless it is peculiarly adapted for embodiments in heavy extruded sections because'relatively heavy extruded sections af ford strength, durability, and firmness, of grip on the) pane far'in excess of that ohtainable with sheet metalfstamped or shell sections. Therefore, in describing the inven-' tion, the use of extrudedmetal isemphasized, although it is not intended to limit the con struction to extruded metal unless specified in the claims.

In thepresent construction the front or outer moulding or section is fulcrumed on the tion liesoutside of the rear moulding or secrear or inner moulding or section ina novel manner and combined with a new frictionor braking joint which prevents too great pres sure from being exerted against the pane when the tension screws are tightened and, also, securely anchors the outer section. or moulding, although it is fulcrumed for ad justmentwithin'a relatively wide range to grip panes ranging in thickness from about one-sixteenth to about one-half inch and yet there is no possibility of the outer moulding or section becoming displacedvertically in -relation to the rear section.

Another feature of the present improvements is that the outer moulding or section instead of being partly contained withinthe rear moulding as in myPatent'1,550,430. This arrangement has several" advantages, among which are, the tension screws, first passing through theoutenmoulding, more easily lind,the holes in theupright portion. at the front ofthe back section and, also, no exposed joint exists to' collect the water,with possibility of freezing in cold weather; still further, the outer and-inner sections of the moulding can be assembledat the factory with greater ease and cut ofito the proper length atthe point of installation.

Those portions of the inner and outer mouldings or sections which are intended to directly contact with the pane are rounded so thatno square or sharp part is presented to the pane, hence danger of cracking or breaking of the pane is minimized when tension is applied to the moulding and when wind, vibration, etc. rock or vibrate the pane or the parts of the moulding.

. It is unnecessary to provide, the conven-,

tional store front jamb or stop when the present moulding is usedlin store frontsetting. \Vhen the construction is employed as a pane holding means for a door, it is not necessary to use a slam. section in conneetiontherewith but when usedion' a swinging casement'window, the construction is well adapted to be combined with a slamstrip or section. 7

' In'my pending application Serial No. 145,-

,824, aforesaid, provision is made for relative flexibility as between thefront and .rear 'sections. The present construction ma have this function and in that respect embo ies im-- provements over the construction shown. in said application. I

Those embodiments of the invention which are hereinafter descr bed and which appear in the drawings are some of the principal forms the invention may assume but it is to Fig. 4, is a vertical section showing the manner in which the improvements may be embodied in a frame for a door, also illustrating by full and dotted lines, the adj ustability of the outer section to accommodate panes of diflerent thicknesses, it-being understood that the tension screws are used, though not shown;

Fi n 8, illustrates how the rear moulding may e rovided with ears for the attachment to t is outer section to afford additional flexibility; Fig.'9, is a vertical section showing the 1 form of -Fig. 8 applied to a pane; and i Fig. 10, illustrates another modification wherein'the front of the rear section com prises supplemental pieces constituting clips which may be of an desired thickness to afford the desired flexibility, when flexibility is re uired. I

hile the front part of the rear moulding ma be made as supplemental clips, as shown in ig.10, nevertheless the construction comprises a front moulding 1 and a rear mould inggQ. p

eferring first to Figs. 1', 2, 3, +1, thc'mouldings 1 and 2 are of relatively heavy extruded metal and, as shown in Fig.3, they are teInsioned b screws 3 at different points of the length t ereof, only one being shown. The sections 1 and 2 have inclined upper parts which are provided with curved or rounded surfaces 4, 5 where they are adapted to engage the pane 6. Thus, nosharp edge or square shoulder engages the glass pane 6 and liability of cracking or chipping from undue pressure or vibration ormovement due to the wind or any cause, is prevented.

The sections 2 may be provided with a gut tern! as shown in Figs. -5, 7, 8, 9, 10, if the installation requires a gutter and drainage. If the gutter is provided, holes 8 at different points of the len th of the moulding 2 will be provided as illustrated in Fig. 5 and the front of the moulding 2 and of the moulding 1 will have drainage holes 9 so that the water entering the moulding will pass to the exterior of the installation.

The manner in which the section 1 is fulcrumed on the front of the section 2 and frictionally seated thereon, represents improvements over the fulcrumed construction found in my Patent 1,550,430. However, as shown by contrast in Figs. 3, 6, 7, for instance, the principle in that respect may be embodied informs differing in detail.

In Figs. 1, 2, 3, 4, the section 2 is provided with a front wall 10 which is spaced in advance of the pane 6 to a suitable extent to permit of the functions hereinafter described and which has a square shoulder 11. The

upper edge of the front wall 10" is rounded from front to rear as shownat 12.

The section or moulding 1 has a knife edge or fulcrum 13 which engages the shoulder 11 and fulcrums on said shoulder as shown in Figs. 3 and 4. The clearance illustrated at His such that a very considerable swinging movement of the section 1 is possible so that a pane of glass varyin from one-sixteenth to one-half inch in thic kness may be accommoplatedland gripped between the parts .1. am 5.

The section 1 is provided with an arc shaped inner surface 15 which is struck on substantially the same are as that of the surface 12, said surfaces being in contact and constituting a combined retainer and friction brake 1, in connection with the fulcrum 13 and shoulder 11 serving the following purposes. Regardless of how tight the screws 3 are drawn up, a frictional checking action is brought about between the surfaces 12 and 15 which prevents undue pressure being exerted onthe pane 6. Also, the section 1 is interlocked with the front wall 10 in such manner that the tension exerted by the screws 1 3 cannotcause vertical displacement of the section 1. The clearance space 16 between the section 1 and the front'wall 10 permits the swinging or tilting movements illustrated in Fig. 4 so that panes of different thicknesses may be accommodated.

Differing from the relative arrangement of front and rear mouldings shown in my Patent 1,550,430, the lower part of the section 1 lies outside of the front wall 10 of the section 2 so that an unbroken surface is provided on theexposed part of the moulding and no joint exists in which water can accumulate and freeze during cold weather. more, by reason of the section 1 being located outsideofthe front wall 10, and the screws 3 passing through section l, it is much easier for the screws to find the screw threaded holes 17 in the front wall 10 and assembly is Furthereasier and also the moulding is'rendered selfcontained and can be more easily cut off and set up where it is to be installed.

In Fig. 3, the construction is shown in connection with a casement window whose frame appears at 18 and there may be provided a slam piece 19', whereas in Fig. 4, when the construction is embodied in a door or sash, the sash or door frame 20 alone is used, as no slam strip is necessary.

In F ig. 5, where the construction is combined with a sill 21 and a stop 22, any suitable fastening means 23 may be used for securing the section 2 to the sill. The condensation gutter 7 may be employed, as previously described. In lieu of the knife edge or fulcrum 13, the form of the invention shown in Figs. 5 and" 6 is provided with a bead or edge 24 whose surface is of general circular shape and which has contact with the walls of the shoulder 11 at the points 25, 26. The resultant effect is the same as with the construction shown in Figs. 1 to 4. As shown by dotted lines 27, Fig. 1 and full lines 27, Figs. 5, 6, 7, 9, 10, the under surface of the horizontal part of the section 1 is inclined when the'construction is intended for use in 'connection'with a sill or the like because this is necessary in order to afford the requisite clearance required by different positions of. adjustment of the section 1 according to the thickness of the pane 6 and to facilitate adjustment under any circumstances.

In the construction shown in Fig. 7, in lieu of the square shoulder 11, on the front wall 10 of the section 2, there is provided a concave d shoulder 28 for the bead-likefulcrum 24. Furthermore, instead of the upper edge of the front wall 10 being struck on the arc of a circle corresponding to the curve 15, the said upper end of the front wall 10 is bevelled as shown at 29 which facilitates the drawing together of the sections 1 and 2 by the screws 3. At the same time, the general frictional effect previously described, is obtained in this modification.

In Fig. 9, the dotted lines 30 illustrate how, the front wall 10 of the section 2 may have a certain amount of adaptability to flex. This is accomplished by the useof spaced lugs.

tenings 32 to the bottom of the section 2 and provided with screw threaded holes similar to the holes 17 for engagement by the screws 3. These clipshaveja re-bent part 33 which, in connection with the front edge of the bottom of the section 2, constitute a shoulder 11 similar to the shoulder 11. The upper part of, the clip has a curved top surface 34 for engagement with the curved face .15 of the section 1. I certain amount offlexibility, enabling the pane 6 to be gripped somewhat more elastically than in the constructions heretofore described. g g g .It will 'be understood, however, that I do not limit myself to clips 31 which are of the The clips 31 afford a relatively thin constructionillustrated, as

they may have the same thickness as the lugs 10.
