PLATE-GLASS STRUCTURE.

Specification of Letters Patent.

Patented May 12, 19114.

To all whom it may concern;

Be it known that I, BERTHA Kenn, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Plate-Glass Structures, of which the following is a full, true, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to glass structures, such as show cases and the like, and has particular reference to means for rigidly binding together the various glass plates thereof.

A primary object of the invention is to provide means whereby a plurality of glass platescan be quickly and rigidly secured together in a convenient and easily practicable manner and without weakening or injuring the glass.

A special object of the invention is to provide corner clamping and finishing means whereby two relatively angularly disposed glass plates having end portions thereof in abutment may first be secured rigidly together, and atop plate be then adjustably secured to the said angularly disposed plat-es, and whereby irregularity in alinement of the plates may be compensated for, and tightjoints may be obtained.

The invention consists generally in corner clamping and finishing means, comprising a pair of corn-er members, one of which is arranged at the outside adjacent corners of two relatively angularly disposed glass plates and the other one of which is arranged at the inside corners of said plates, means for drawing the corner members together securing them firmly to the glass plates and binding the two glass plates ri idly together, a hood-like member adjustabl y connected to said corner members for securing a top plate to said side and front plates.

The invention consists further in certain novel features of construction, arrangement, and combination of parts whereby the aforementioned objects and certain others here inafter appearing are attained, as will be more clearly understood by reference to the accompanying drawings, and as particularly pointed out in the appended claims.

Figure 1 is a perspective view, viewed from beneath, of a show case corner embodying my invention; Fig. 2 is a side elevation of a corner of a show case equipped with plate securing means embodying my invention; Fig. 3 is a top plan view taken from Fig. 2; Fig. 4 is a sectional elevation on the line 4P of Fig. 3; Fig. 5 is a sectional view on the line 55 of Fig. 4: looking in the direction of the arrows; Figs. 6 and 7 are perspective views respectively of the outside and inside corner cover memhers used to secure the front and side plates of a glass case together; Fig. 8 is a perspective view of a circular plate adapted to be inserted in the member shown in Fig. 6 and on which the name of the manufacturer may be stamped; and Fig. 9 is a perspective View of the corner member whereby the top plate is secured to the front and side plates.

This invention has to deal particularly with the so-called all-glass show cases, that is, a show case composed mainly of sheets of plate glass secured together without a frame of strips or holdings. I prefer to provide means located at the corners of the show case for binding the various sheets of plate glass into a rigid structure as they can be there applied without weakening the glass. In plate glass show cases, as now constructed, it is extremely dillicult to apply the means for binding the front, side and top plates of the show case together, because it is customary to use a corner member which necessitates the securing of the three plates together simultaneously. To apply securing means of this construction not only required an expert, but also it is practically impossible to form a thoroughly tight joint. And further it is necessary to provide a special tool for tightening the securing means. The present invention discloses means for overcoming these undesirable features, and provides means which can be easily applied even by a layman and by the use of which a tight fit between the front plate, side plate, and top plate of the show case is secured.

In the preferred form of the invention shown in the drawings, 1, 2, and 3 are respectively the front, side, and top plates of a glass show case. The term front and side plates as here used shall mean any two relatively angular-1y disposed glass plates having end portions thereof in abutment. In order that these plates may be easily de' soribedwith reference to the other parts of the show case, they shall be considered as occupying vertical planes. It should, therefore, be understood that the angular relation between the front and side plates may be as desired, and that the abutting end portions may also be arranged at any desired angle.

The term top plate as here used shall mean any glass plate arranged in intimate relation with the edges of a side and front plate. Although the top plate is usually the upper plate of a show case,-it may be used 'in the same relation for the bottom of a show case. For purposes of ease in de scribing the top plate with reference to the other parts of the show case, it will be considered as occupying a horizontal plane and as resting substantially upon the upper edges ofthe side and front plates.

4 and 5 are corner clamping members by means of which the front and side plates are bound together, the member 4 being arranged at the outside corners of the frontand side plates and the member 5 at the inside corners thereof. The members 4 and 5 are preferably composed of metal, and on the show case shown are made in the shape of a triangular pyramid, the side portions 4" of the member 4 abutting the outside faces 1 and 2 of the front and side plates 1 and 2, and the portion 4', which shall be hereinafter termed the upper side portion, projects over the edges 1 and 2 of the front and side plates. One important function of the portion 4 is to connect the side members 4 and 4 to prevent their spreading part when being secured to the glass. The member 5 is similar tothe member 4 having sides 5, 5", and 5. When the parts 4 and 5 are applied to the glass, the side portions of the member 5 are parallel to the side portions of the member 4, as is best shown in Figs. 4 and 5. A stud, 6, secured in the corner of the member 4 between the sides 4 and 4" thereof, projects inwardly at an angle of approximately 45. It is tapped to accommodate a binding screw 7 which is provided with a head 7 so made that the sides 7' and 7 thereof are parallel to the sides 5' and 5 of the member 5. The shank portion 7 projects through an opening 5 provided therefor in the member 5. The shank 7 is threaded and enters the tapped stud 6. By means of the screw 7 the members 4 and 5 may be drawn together and thereby firmly secured to the glass plates 1 and 2.

As is best shown in Figs. 4 and 5 the plates 1 and 2 are cut away as indicated at 2 and 2 to accommodate the stud 6 and the screw 7. Cutting away the glass at the corners in this manner, however, in no way weakens it. Thus it should be apparent that by means of the members 4 and 5 the front and side plates 1 and 2 can be firmly secured together in a simple manner and that by the use of these at the other corners a substantially all-glass structure can be made.

lVhile there are many cases in which it is desirable to secure but two plates of glass, such as plates 1 and 2, it is frequently necessary to secure a top or cover plate 3 to the plates 1 and 2. Hence I provide means whereby the plate 3 can be secured to the plates 1 and 2. member 8 having a corner portion 8 composed of upper and lower portions 8 and 8 which are spaced apart to accommodate the desired thickness of glass. A strip or tongue 8 projects from the lower portion These means comprise a 8 in which a slot 9 is provided. The Ineni-v bers 4 and 5 are cut away, as indicated at 4" and 5 and through these openings the tongue 8 pro ects as is'best shown 111 Fig.

4. It will beseen by reference to Fig. 4. that the portion 4 of the member 4 and the portion 5 of the member 5 abut, and that the tongue 8 extends below and'substantially parallel to the portion 5 of the member 5. A tapped hole 8 in the portion 5 of the member 5 accommodates a binding screw 10 by means of which the members 8 and 5 are secured relatively immovable, thereby securing the top plate 3 rigidly to the plates 1 and 2. r

It will be noticed that the edge portions 7 3 and 3 of the top plate 3 project over the front and side plat-es, 1 and 2f1n some cases it is desirable to vary the amount of projecting portions 3 and 3 and this is accomplished by providing the slot 9 in the tongue 8 which permits any desired projection of the portions 3 and 3". Another feature of the adjustablemember S is that in case the edges 8 and 3 are cut slightly inaccurate the member 8 can still be brought into intimate contact therewith. It will be noticed that the top plate 3 rests upon the portion 4" of the member 4 and, as this rests upon the upper edges 1 and 2 of the plates 1 and 2, the plate 3 is held thereabove. It is not practicable to do without the portion 4" as it rigidly braces the side portions 4and 4" and it is not desirable to cut away the glass to accommodate this portion, hence the space between the plates 3 and the top edges of the plates 1 and 2. This space, however, is easily filled by means of a strip of felt or other suitable material 11 which is preferably glued to the edges 1 and 2 of the members 1 and 2.

In order to accommodate the end of the screw 10 the portion 4 of the member 4 is cut away at 4. To hide the screw from view, I providea thin plate 13 which fits the opening 4 of the member'4, and which may be used as a name plate. The plate 13 being very thin allows the screw 10 to proj set through the member 5, without binding the plate against the glass.

To construct a show case by the means here disclosed the side and front plates are secured together with the corner members I and 5. An ordinary screw driver is the only tool necessary for tightening the members I and 5 bymeans of the screw 7. The screw 7 may be easily gotten at, as the top plate is not yet in place. After the plates 1 and 2 have been firmly bound together, the top plate 8 is placed thereon and the corner member 8 placed in position on the plate 3 and then secured by means of the screw 10, thereby binding the plate 3 firmly to the plates 1 and 2. Thus the objects set forth are attained in the device as shown and further the invention as disclosed provides a glass structure which is of substantial cOnstruction and also of pleasing appearance, as the plate glass securing means also constitute corner finishing means for the glass.

As various modifications of the invention will readily suggest themselves toone skilled in the art to which it appertains, I do not confine or limit the same to the specific structures herein shown and described.
