4 Claims.

The invention relates to store front construction employing metal strips -or bars for the reception of the glass, and constitutes an improvement on the structures of the F. W. Currier Patents Nos. 1,458,397 and 1,458,398. It has for its principal objects, the provision of a construction which is easily applied and presents an improved appearance; the provision of a construction having improved clamping members for the glass positively guided into position, so that when the securing screws are applied, one flange of the member is pressed against the glass, and the other flange which extends at right angles thereto, is maintained in contact with the flange of the rear sash bar, and thus provides an adequate securing or locking means for the cover plate; the provision of improved means for securing the cover plate releasably in position; and the provision of a construction in which the flange of the rear sash bar or back strip acts as a guide in positioning the paneling surrounding the window and serves as a iinishing strip for the edges of said paneling. Certain embodiments of the invention are illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective sectional view of one form oi the construction. Fig. 2 is a detail perspective view. Fig. 3 is a detail perspective view showing a modified form of clamping member. And Fig. 4 is a perspective view showing a modification.

Referring to the construction shown in Figs. 1 and 2, 1 is the sash frame of the usual Wooden construction; 2 is a metal sash bar which is seated in the sash frame and secured in position by means of the screws 3; 4 is one of a number of clamping members moved into clamping engagement with the glass plate by means of the screws 5; 6 is the glass plate which is clamped between the sash bar and the clamping members; 'l is the cover strip or plate which lies over the clamping means and has releasable interlocking engagement with the clamping members as later described; and 8 is an ornamental paneling preferably of carrara glass lying in front of the sash frame 1 and positioned with respect to such sash frame by means of the usual plastic cementing material 9.

The sash bar 2 and the cover strip 7 are preferably yextruded metal sections, While the clamping members 4 are formed of sheet metal bent to the desired shape. 'Ihe showing in Fig. 1 is that of the construction at the bottom of the window, but it will be understood that a similar construction is used at the sides and top with the exception that the gutter 10 which is shown in Fig. 1 is not required in the construction at the sides and top of the window.

The sash bar 2 consists of a back strip 11 whose upper edge engages the rear face oi the sheet 6 (Cl. 18o-56.4)

and a base strip 12 which lies at right angles to the back strip and extends forward a substantial distance to the front of the sash frame 1 so as to provide a space for receiving the panel 8. The sash bar is installed before the panel 8 is applied so that the base strip 12 thus becomes a guide for the location of the panel 8 whose iront face lies flush with the edge of the base strip. The base strip thus acts as a finishing strip for the upper edge of the panel materially adding to the appearance of the construction and protecting the edge of the paneling from chipping or other injury. The sash bar is also provided with a flange 13 which is spaced above the base strip 12 to provide the guide slot 14 in which the clamping member is guided, as later described. The flange 13 also acts as a support for the Wooden blocks 15 (Fig. 2) upon which the lower edge of the glass plate 6 rests. The clamping members 4 each comprise an upright clamping plate 16 and a base plate l? which rests upon the base strip 12. At the juncture of the clamping plate and base plate is a flange 18a which lits into the slot 14. The base plate is provided adjacent its outer edge with a locking groove 18, while the upper edge of the clamping plate is provided with a locking flange 19. These locking devices cooperate to hold the cover strip 'l in position.

The cover strip '7 may be of any desired ornamental coniiguration, and is provided at its inner edge with a flange 20 adapted to lit beneath the flange 19 when the cover strip is pushed into position, as indicated in Fig. 1. The outer edgey of the cover strip is provided with a recurved flange 21 carrying a bead 22 adapted to lit into the locking groove 18 when the parts are positioned as indicated in Fig. 1. The cover strip is positioned by resting it upon the base strip 12 and sliding it inward in a direction at right angles to the glass plate until it arrives at the position indicated in Fig. 1,-at which time it is locked in position by the interlocking parts on the clamping members 4. 'In order to detach the cover plate, a screw driver or other tool is pushed in between the plate 6 and the edge of the cover strip and twisted, thus springing the cover strip outward until it is released from engagement with the flange 19 and locking groove 18. The outer edge of the cover strip is preferably provided with a 'bead 23 which projects out past the edge oi the cover strip 12. This not only gives an ornamental appearance, but permits or" an adjustment oi the cover plate in and out due to the use oi different thicknesses of glass without detracting from the appearance of the construction or giving any indication that such adjustment has been made, such as would be the case-if the bead 23 were not used and the edge of the cover plate came flush with the edge of the base strip. It will be noted that the cover strip entirely iills the space between the panel 8 and the glass plate 6 so that a distinctive appearance is secured with only the coverl strip and the edge of the base strip 12 showing between the two glass members 6 and 8.

'I'he use oi.' the guide slot 14 is connection with the iiange 18a on the clamping member 4 is of substantial advantage as it acts as a stabilizer for the clamping member when it is moved in by the clamping screws 5, and any tendency of the base plate 12 to spring up due to the bending in oi' the clamping plate 16 under the action of the screws is avoided. If the guide device were not used, the base plate carrying the locking groove 18 would either be sprung up or oiIer very little resistance against moving up, so that the locking engagement with the bead 22 on the cover strip wouldnotbesecureandiirmasisthecasewith the construction as shown in which the base plate 17 is held rmly against the base strip l2.

In order to insure against any engagement of the edge of the glass plate 6 and the screws 5. the separator members 24 shown most clearly in Fig. 2 are employed. These separator members are provided with tongues 25 which are pressed out and lie between the screw and the edge of the glass plate, as indicated in Fig. l, so that the edge of the glass plate is protected from possible injury by reason of accidental contact with the screws. In order to hold the separator members in position in the sash bar, the recess in which they iit is preferably beveled away slightly, as indicated at 26 and 27 (Fig. 2). The separator members are thus yieldingly held in the position in which they are placed in the recesses in the sash bar.

Fig. 3 illustrates a modiilcation in which the clamping member 4a is not provided with a continuous base plate, such as is shown at 17 in Fig. 2, but instead isprovided with a pair o1' spaced plates 17a, which serve the same tunction,'but which oiler less resistance to the insertion and removal of the cover plate than the continuous base plate 17 oi the Fig. 1 construction.

Fig. 4 illustrates a modiilcation in which the cover plate 7b is oi' diilerent contour from the cover plate 7 shown in Fig. 1. It will be understood that a. wide variety of ornamentation and conilguration may be employed in the cover strip. This construction also shows a base strip on the sash bar 2b which has at its outer end a downwardly turned ange 28 which is ilush with the outer face o1' the panel 8. 'I'he sash frame in this construction includes the wooden member 29 and the angle member 30. The panel 8 is not necessarily of glass, but may be marble or metal or of wood coated with metal sheathing or of any other suitable material.
