STORE-FRQN'T CONSTRUCTION.

Application filed September 10, 1924. Serial No. 736,876.

The invention relatesrto store frontcon structions of the type shown in our application, Serial No.897.940, filed July 21st,

close the-jconstr uction; Fig. 2. is'an elevation looking atthe rear of the front or cover strip; F 3 15 a section on the line TIIIII of Fig. Rig. 4 isa perspective View showng the construction at one of the clamps with the glass and front strip removed;

l lig oais a plan view-of the bottom of the clamp showing its roughened surface, and Fig-,6 1s a plan view of the bracket upon which the clamprestsn I lieferringito the drawings, 1 and 2 are the wood'members constituting the framework in which the metal sash-bar construction mounted. Mounted upon the member 1 is the sheet metal back strip 3 having integral with its lower edge the strip 1, which will be referred to as the base strip. The back strip 3 is provided at intervals with pressed out or embossed portions 5 for engaging the rear face of the glass sheet 6. The spacing of these members at intervals gives drainage spaces for taking care of the moisture collected in the gutter 7 The glass is supported at its ends by the usual wood or fibre blocks, not shown. Spaced at intervals along the base strip 4 are the brackets 8, whose function is to support the clamps later described. These brackets comprise two wings, one of which rests against the base plate 4 and the other of which rests against the back strip 3, the brackets being secured in position by means of the screws 9. As indicated in Fig. 1, the brackets with the clamps carried thereby are placed opposite the embossed lugs 5 so that any pressure applied to the glass by the clamps comes opposite a point at which the glass is supported at its back, so that there is no danger of the pressure of the clamps breaking the glass. The brackets are provided with flanges at 10 and 11, so that the intermediate portion is spaced above the base strip 4:, thus permitting a free flow of water along the base strip. The upper face of the base portion of the bracket is rough or corrugated as indicated in Fig. 6, and a threaded perforation 12 is provided for receiving the end of the screw which holds the clamp.

Mounted upon each bracket is a clamp 18. These clamps are provided with key hole slots 14, so that the clamp may be positioned over itsholding screw 15 without removing the screw from position. The

lower face of this clamp is roughened or corrugated as indicated in Fig. 5, so that this roughened surface is in opposition to that of the bracket 8. This is to avoid any danger of a clamp slipping after the holding screw 15 has been tightened. In order to obviate the danger of the screw becoming loosened, a spring washer o1, nut lock 16.

is preferably en'iploycd. The inner edge of each clamp is provided with a holding lug or hook 17 to provide interlocking engagement between the clamps and the front or cover strip. 1

The front'or cover strip .18 has its outer and inneredges made in hook form, as indicated at 19: and 20, the hook portion 19 serving to interlock with the hook portion 21 on the base strip, while the hook portion interlocks with the lugs or hooks 17 on the clamps. The front strip is provided at intervals with slots 22 to facilitate the application of the front strip. This is accomplished by first interlocking the lower hook edge of the front strip with the outer edge of the base strip and bringing the slots 22 opposite the hooks 17, after which the inner edge of the front strip is pressed in against the glass and the strip then moved longitudinally a fraction of an inch to bring the parts to interlocking position.

In setting the glass such glass is first positioned on its wood blocks and the clamps 8 positioned on the brackets and pushed up tightly against the glass, after which the screws 15 are tightened. The glass is now securely held in position and all that remains is the application of the front or cover strip 18, which is applied in the manner above described by first interlocking the strip at its lower edge with the base strip, and after the slots 22 have been positioned over the hooks 17 on the clamps, the cover strip is moved longitudinally until interlocking engagement occurs. The construction is cheap and simple and is quickly and easily applied or removed. The parts may all be stamped out of sheet metal and the screws applied in the brackets preliminarily to the operation of setting the glass.

The spacing of thebase of the bracket away from the base plate 4 as indicated in Fig. 3, not only permits any water which collects to move freely longitudinally of I the sash until it arrives at a point of escape, but also provides additional space for the screw 15, so that longer screws may be employed with less danger of losing the screws out of the brackets in handling than would 7 otherwise be the case, The use of the em bossed lugs 5 eliminates the necessity of applying separate filling strips which would add to the expense ofthe construction. The use of the relatively short lugs or hooks 1'7 permits of theuse or a correspondingly short perforation 22 in the, front strip, so that there is less interference with the machine operation of bringing the front strip to'its' form'of use than would be the case if these slots were longer/f The use of the key hole slots facilitates the assemblying of the clamps and brackets, and the use of the roughened. surfaces on these parts in connection with the spring washers prevents any accidental loosening of the clamps such work comprising spaced supporting brackets fixed with respect to the framework, angular and having threaded engagement with the brackets, interengaging means on the opposing'surfaces of the brackets and clamps to prevent their relative movement when the Screws are tightened and a front or cover strip secured 'releasably to the clamps, the

saidscrews being accessible from the front 7 of the glass when the cover strip is removed.

2; In a storefront construction, means for securing a glass ina supporting framework comprising spaced supporting brackets fixed with respect to the framework and having their end portions provided with downwardly'projecting flanges extending longitudinally of said framework, angular clamps mounted on the brackets for movement toward and from the glass, and each comprising a glass engaging wing and a slotted bracket engaging wing, fastening screws for the clamps lying in the slots in the wings forward of the glass and having threaded engagement with the brackets and a front or'cover strip releasably secured to the clamps, the said screws being accessible from the front of the glass when the cover strip is removed. 1
