STORE-FRONT CONSTRUCTION.

Application filed July 21, 1920. Serial No. 397,940.-

Tlie invention relates to store front constiuctioiis. It has for its primary objects the provision of an improved construction which permits the setting of the glass with a: minimum labor' cost; which is of simple construction and relatively low cost; in which a maximum clearancel is afforded between the edge ot the glass and the metal fixtures surrounding it, so that breakage due to settling and consequent engagement ot the edge ot the glass withv any rigid metal members tending to break the sheet is reduced; and in which the glass can be set entirely fromy the front while at thefsame time avoiding a showing from the front of screws or other holding devices for the metal cap plate tendingto mar the appearance of the construction. Certain embodiments of the invention are illustrated in the'accompanying drawings, wherein:V i

Figure l is a front view ot theassembled construction with portions ot the' glass and front strip broken away to more clearly disclose the construction; Fig. 2 isan elevation looking at the rear oit the front strip; Fig. 3 is a section on t-he line IIIe-III ot Fig. 1'; Fig; 4 isa perspectiveview showing the construction at one of the clampsor securing means with the' glass and front strip removed; Fig. is a view similar to that of Fig. l ot a modified construction', Fig. 6 is a rear elevation of the front strip; Fig. 7 is a section on the line VII-VIT of Fig. 5; Fig. 8 is a section through a modified con struction, and Fig. 9 is a tront elevation of one ot' the securing wedgesl used in the construction of Fig.v 8;

The construction is ordinarily referred t A as a sash bar andV is capable of. a numberot ditlerent embodimentsall involving the same general principle but diil'ering in matter of detail. In' its essentials thev construction comprises, a` back stripadapted to engage the rear side of the glass, a base' strip lying' opposite or below thev edge `ot the glass,

spaced securing means'mounted upon the the base strip, thus holding the lower edge ot such Jfront strip against outwardI move Thev lower edge of the front strip also interlocks with the outer edge ofv thus simplifying the device and giving thel construction a better appearance from the front. In one form of the device provision is made torjinoving the front strip. against the glass as such front strip is moved longitudinallyto lock it in position, this preter-` rENNsYLv'ANIA,

ably being accomplished by meansV ot` v wedges, but in other" forms of the device the application ot the cover strip does not perform this function, the glass being secured in position by means of clamps independent ot the trent or cover strip, and the front strip being subsequently applied inthe manner heretoforeI referred to.

The latter term of construction being the simpler will be described first, reterencebe! ing had to Figs. l to 4, which illustratefthis construction. i As here shown, l is the wood framework in which the sash bar is set, 2 is the glass, 3 is the back strip, 4 is the base strip7 which ink this instance is integral withy thek back strip; are" spaced brackets se-` cured inposition by means oi' the screws 6,v 7 are the clamps mounted slidably upon the brackets for movement toward and from the` glass, and V8 is the front or cover strip.

The back strip 3 may be turnedl outwardlyY as indicated at `9 to provide a gutter, and spaced at. intervals along this strip are leadA bearing strips l0, the spacing oit which proout o'f the inaterialof the base strip 4 andV are of dovetail shape, -as indicated in Fig. 4. The clamps 7 are slotteds'o as to lit theV dovetail brackets 5l and are provided with lugs 112 carrying the screws 13 which provide for clamping the members 7 in any' desired position oiv adjustment, depending upon thethickness-of the glass.

The front strip 8` has its upper edge bentV or hooked over .forming the securing lugs 14 (Fig. 2)-, which are adapted to` be engagedby the clamps 7.- The outer edge ot the base strip 4 is bent up as indicated at 15 to provide aholding recess, and the lower edge of the outer strip is bent back as indicated at 16 to engage in such recess. v

In assembling the device the sheet ofv glass is positioned with its edges resting upon a f pair of wood or fibrel blocks, not shown. The

clamps 7 are then mounted on the brackets 5 and pushed up tightly against the glass, after which the screws 13 are screwed down to lock the clamps in position. The front or cover strip 8 is now applied by hooking its lower edge beneath the edge 0f the base strip as indicated in Fig. 3, with its upper edge bearing against the glass and with the lugs 14 to one 'side of the clamps 7. The strip 8-is then slid longitudinally until the lugs or holding devices 14come behind the clamps. This, of course, leaves a space at one or both ends of the front strip 8, but such spaces are relatively short and are covered by the corner caps ordinarily used in this general type of construction, such corner caps being. fastened in position by the usual screws.

the front of the window and that this operation is relatively simple and easily accomplished. The clamps 7 are easily and rapidly positioned and secured in place and the front strip 8 secured in position at a single operation, the interlocking arrangement at,

the upper and lower edges of this strip giving a very secure attachment and one which is of vneat appearance. The front strip is preferably slotted at its lower edge, asindicated at 17, in order to provide for drainage. It will be noted thata relatively wide space is left at 18 between the edge of the glass and the brackets 5, so that considerable settling can' occur `without danger of the glasscoming in contact with `a rigid metal fixture, which would tend to causeV breakage. n y

The type of clamp illustrated is only one Y of a number which may be employed, such r ments.

clamp being preferably rused because there is no means for pushing them up too tightly Y against the glass and causing breakage, such Figs. `5, 6 and 7 illustrate a modified type of construction in which the clamping action isfsecured by the longitudinal'movement of the front strip, such longitudinal movement serving to lock'the base strip in position andV Vat the same time press it agaisnt the glass, the front stripin this case serving as the clamping means. In this construction 18a is It; will be seen that the coni struction is easily assembled entirely from the wood framework, 19 is the back strip, 20 is the glass, 21 is the base strip, and 22 is the front strip.

In this arrangement what is known as a "kalomine construction is employed behine the glass, such construction involving the strip 19, another metal'strip 23 and a wood filler 23a, the lead bearing strips being omitted in this construction and drainage being permitted either by lack of complete contact'between the strip 19 and the glass or by grooving the strip at intervals, these being well known expedients in the art and constituting no part of the present invention. The base strip 21 is provided at intervals with punched up dovetail lugs 24 to which are securely attached bracket members 25, Leach provided' with two wedge portions 26, as indicated in Fig. 5. The upper edge of the front strip `22 is bent around as shown at 27, to forni a. holding recess, and spaced at intervals in this recess are locking loops 28 (Fig. 6), such'loops being clamped in the recess 27 so that they will move with the front strip. The lower edge of the front strip 22 is preferably hooked round the outer edge of the base strip 21, as .indicated at 29.

Inv assembling this construction, the glass 2O is placed upon wood blocks as in the other form of construction and the front strip is hooked over the outer edge of the base strip with thev locking loops 28 in alignment with the' bracketsV 25. The front strip is now moved longitudinally so that the loops pass over the ends of the wedge portions 26. As this movement continues vthe wedge action pulls the loops 28 downward, thus moving the upper edge of the front strip into contact with the glass, the tightness of such contact depending upon the extent to which the front strip is moved. The friction involved in such movement, however, is such" that it renders it impossibleto apply such a pressure upon the glass as would tend to break it. It will beseen that this sash bar mayV be applied even morequickly than the Y 5 one of the construction of Figs. 1 to 4. Also hookedportion 33 at its outer edge. The.

front strip 34 and'loops 35 are the same as in the construction' of Fig. 7, butthelocking wedge member 36 is somewhat different, such' wedgemember `fitting at its outerV edge in the liookedfportion 33 y'of the base strip and at its inner yedge being held in lposition by means of the machine screws 37 This member36is provided with two wedge parts Alessee? 38, and the method of fitting the glass and applying the front strip is the same as described in connection with the construction of Figs. 5, 6 and 7.
