GEORGE G. HESTER, OF CHICAGO, ILLINOIS.

Application filed August 29, 1916.

To all whom it may concern:

Be it known that I, Gnonon C. Hnsrnn, a citizen of the United States, and resident of Chicago, in the county of Cook, and in the State of Illinois, have invented a certain new and useful Improvement in Corner and Division Bars for Store-Front Constructions, and do hereby declare that the following is a full, clear, and exact description thereof.

In the well-known plate glass store front construction, what are known in the trade as corner and division bars are employed at the vertical corners and other division points in the front between adjoining plates of glass, to secure them in position thereat. The angles of the plates of glass that form the corners, greatly vary, and while ,attempts have been made by others to provide a corner bar construction that would be adaptable to various angles, yet as far as I know to the contrary, the attempt has never succeeded, but the present practice is to provide a different corner bar for each angle. This requires a great assortment of corner bar angles, and even then difficulties arise because of failure of a particular corner bar and the glass plate as installed, to accurately agree, through error or carelessness of workman. Such lack of agreement results in failure of proper support be given the glass, and danger of breaking it by forcing an agreement. The object of my invention is to provide a bar construction which will have such flexibilty or scope of adjustment that the same bar will suit any angle required, and,-if desired, even to the extent of an angle of 180, degrees, so that a great variety of corner bars and separate division bars, as such, is not necessary, but the one construction will serve all purposes and efficiently and with entire practicability meet all requirements. Other objects and advantages of my invention will be understood by those skilled in the art when the embodiment of such invention shown in the drawings, is more fully explained in the following specification, of which said drawings form a part.

In the accompanying drawings- Figure l is a perspective view of a bar embodying my invention;

Serial No. 117,420.

My bar, briefly described, comprises as I the necessities of the case require, glassengaging members in the form of duplicate pairs of vertical rails, between which, and the adjacent edges of adjoining plates of glass, clamping bolts or screws are passed, by which the rails of a pair, situated, respectively, on opposite sides of the same plate of glass are caused to exert the desired clamping pressure thereon. These rails are made of sheet metal, such as copper, of sufficient thinness to enable great lengths thereof readily to be bent or shaped into the desired form in cross section.

In the form of my invention shown in the drawings, the inner and outer members of each pair of rails are pivoted to each other on a longitudinal axis and the corresponding parts of the opposite pairs are pivotally connected on such an axis so that the two members of a cooperating pair, which for convenient designation I shall term plates, may be spaced apart a distance corresponding with the thickness of the plate of glass 10 to be engaged thereby, one of which plates 11 is on the outer side ofthe plate 10, and the other plate 12 is on the inner side thereof, and their pivotal connection with each other and with the corresponding members of the other pair lies in the space between the edges of the two adjoining plates of glass and all four plates being provided with a flat glass-em gaging portion which is the outer part of the plate and a concavo-convex curved portionthatreaches fromtheflat,orplaneportion to'the pivotal connection between the plates which may readily be formed by a more or less complete tubular portion on the inner edge of each plate, the various tubular portions being of different diameter so that one may be applied to the other in a concentric arrangement, the innermost one being a complete round tube. By the pivotal connection thus formed, each pair 0 plates may and inner glass-engaging plates of a pair toward each other to clamp the plates of glass therebetween, comprising a bolt, a clip with which the bolt is connected that straddles the flexible connection between the pair of outer plates, and a bar outside of the outer plates with which said clip is connected.

3. A glass clamping device comprising two pairs of glass-engaging plates that respectively engage outer and inner sides of the plates of glass, the plates of a pair being flexibly connected with each other, and the two pairs being flexibly connected together at a point between the two plates of glass to be held, and the inner pair of plates having a lip and slot connection, and means for drawing the outer and inner glass-engaging plates of a pair toward each other to clamp the plates of glass therebetween.

4. A glass clamping device comprising two pairs of glass-engaging plates that respectively engage outer and inner sides of the plates of glass, the plates of a pair being flexibly connected with each other, and the two pairs being flexibly connected together at a point between the two plates of glass to be held, and means for drawing the outer and inner glass-engaging plates of a pair toward each other to clamp the plates of glass therebetween, comprising yieldable arms that engage the respective inner plates, and a stop to limit the movement of said arms toward each other.

5. A glass clamping device comprising two pairs of glass-engaging plates that respectively engage outer and inner sides of the plates of glass, the plates of a pair being Copies of this patent may be obtained for flexibly connected with each other, and the two pairs being flexibly connected together at a point between the twoplates of glass to be held, and means for drawing the outer and inner glass-engaging plates of a pair toward each other to clamp the plates of glass therebetween, comprising a bar having yieldable arms that bear against inclined surfaces on the respective inner plates, and a stop on each of said inner plates adjacent said arm.

6.. A glass clamping device comprising two pairs of glass-engaging plates that respectively engage inner and outer sides of the plates of glass, a flexible connection between said pairs of plates, and means to cause the opposite plates of a pair to clamp an interposed plate of glass, said pairs of plates being self-adjustlng on the flexible connection between them to conform to the angular relation of the plates of glass.

7. A glass clamping device comprising two pairs of glass-engaging plates that respectively engage outer and inner sides of the plates of glass, all of said plates being pivotally connected to each other on a common axis, means connecting the plates of each pair to enable them to be handled as a unit while permitting rocking movement of the plates upon their pivotal connection, and means for drawing the outer and inner glass-engaging plates of a pair toward each other to clamp the plates of glass therebetween.

In testimony that I claim the foregoing I have hereunto set my hand.

GEORGE C. HESTER.
