/NVNTOR zgn/Af@ Patented Dec. l5, 1931 i ALBERT H. MARTY, OF CLEVELAND, OHIO MOUNTING FOR PLATE GLASS WINDOWS Application led November 3, 1928. Serial No. 316,999.

VThis invention relates to mountings for windows such as are used in store front or display Window construction, show caseconstruct-ion, door construction, transom construction, sash construction, and the like.

More specifically, in the embodiment illustrated this inventionV discloses an improved mounting of this type in which the constituent elements are relatively heavy seclt tions. rThese sections are preferably formed by extrusion and composed of non-corrosive metals such as bronze, brass, or other suitable alloys. It is to be understood, however, that this invention is not limited to the use f of metal as other materials may be used without departing from the spirit ofV my invention.

One object of this invention is to produce an improved mounting for windows which 1s strong, substantial and durable in construction and handsome and artistic in appearance and composed of sections not likely to beinjured or distorted in normal handling or in the usual manufacturing hazards and which are not easily disfigured or sprung in use.

Another object of this invention is to produce an improved mounting for windows in which the elements are simple in -form and easy to produce and which are economical to fabricate and erect and which are easy to dismantle` for removing or renewing the glass when replacements become necessary.

A further object of this invention is to prov duce an improved mounting for windows in which the outer clamping member is uniform in appearance throughout its, length and free from any openings, projections or recesses required for adjustments, so as to facilitate cleaning or polishing'and to eliminate the accumulations of polishing material 'at or adjacent to the irregularities. i

A further object of this invention is to produce an improved mounting for Windows in which there are no tightening means on the invisible from the exterior of the glass and, in fact, a. mounting in which the tightening means are completely concealed either from an exterior or interior observer.

5@ A further object of this inventionl is to proexterior, in which the tightening meansV arev duce an improved mounting for windows in Vwhich the outer clamping member is of uniform section throughout its length and in which any portion will co-operate with the devices for drawing this clamping member toward the glass, that is an outer clamping member in which there are no regularlyv spaced holes, projections or attachments which must register with correspondingly spaced adjusting devices on the stationary member.

A further object of this invention is to produce an improved mounting for windows which utilizes an improved form of tightening device purposed to hold the glass accurately and firmly in position and yet in a yielding or resilient mannerA so that the glass will not be subject to danger of fracture.

' A'further obj ect of this invention is to produce an improved mounting for windows speciallyadapted for that type of display window having an inclined display board approximately adjacent to the inner edge of theV mounting.

. 'A further object of this invention is to produce an improved mounting for windows provided with a novel type of moisture collecting trough. Y

Further objects and advantages of this invention will appear from. the ollowingdescription and uponl reference to the accompanying drawings.

The annexed drawings and the following description set forth in detail certain means embodying this invention, such disclosed means constituting however, but a few of the forms in'which the principle of my invention may be applied. A

Fig. v15 isa view similar to Fig. 8 showing Vanother Vslightly modified form of this invention.

I shall first describe the form of the invention illustrated in Figures 1 to 10 inclusive, wherein my invention is shown applied to store front construction. While, as illustrated, .this mounting is shown supporting the lower edge of a window. it will be. understood lthat the same or similar construction may be used for the side or top of the window.

' In .these figures, 1 indicates the glass to be mounted and 2 represents the frame or sill of the building upon which this improved window mounting is placed. This sill may be constructed ofany suitable material, wood being shown in the illustrations. The outer face 3 of this sill may be finished with wood, cement, granite, marble, or other durable and artistic facing material. The display space interiorly of the glass 1 may be flat somewhat as shown in Figure 8, or may be occupied by a display board l placed in position close to the window as is shown in Figure l. An open space 5 is left between the display board i and the window mounting for a `purpose to .be hereinafter pointed out.

The main or base member of my improved mounting is a stationary or inner clamping member 6 which is secured to the building sill by means of screws, expansion bolts, or in any other manner desired. The type of connection selected will depend to a large ei:- tent upon the material of which the building frame is made, wood screws 4' being suggested as the connection, in the drawings. The statienarv member 6 is formed with a contacting lip 8 at its upper end adapted to engage the inner face of the glass 1, which is to be supported. Adjacent to the contacting lip. 8 the stationary member is perferably formed with an arcuate trough 9 intended for the collection of moisture of condensation which forms on the window. For the purpose of ldraining the moisture from this trough., weep holes 10 are provided. The inner or lower edge of this trough is bounded by a flange 11 which pre-jects vertically from the lowermost point of the arcuate curve as shown. The stationary member 6 is further .formed with a vertical wall 12 which is substantially in vertical alignment with the flange 11 and which forms the eXtreme rear or inner portion of the member 6. The stationary member 6 is further provided with a horizontal iiange 13 which extends outwardly from the base of the vertical flange 12 to a point considerably beyond the plane o'f the window as clearly shown in Figure 1. This flange 13 terminates with a down-turned edge 14, which, however, forms no part of my invention. This stationary member 6 is illustrated in the detached fragmentary perspective view, Fig. 3.

The outer or movable clamping member 15 is formed at its upper end with a contacting lip 16 which is adapted to contact the glass 1. The lower edge 17 of this outer clamping member 15 tightly contacts the fiange 13 of the stationary member 6. The intermediate portion 18 of this outer clamping member may have any contour which is desired to satisfy the artistic appearance required. Attached to this intermediate portion 18 of th-e clamping member is a reversed or re-entrant lip 19, this lip being reversed or re-entrant in the sense that it points in direction opposed to its clamping movement. This lip 19, in the form of the invention shown in Figures 1 to 10 inclusive, is connectedto the intermediate portion 18 of the outer les.

clamping member 15 by means of a relatively7 thin web 20. Drain openings or recesses 21 are provided in the lower edge of this outer clamping member 15 to permit the escape of any moisture which may have drained in through the holes 10 or from any other source. This outer clamping member 15 is clearly shown in the detached fragmentary perspective view, Figure 4. Mounted for sliding movement on the hori- -zontal `flange 13 of the stationary member 6 is a bracket 22. This bracket is formed at the left or outer end with-a reversed lip or hook member 23 adapted to i interlock with the reverse lip 19 on the member 15, this lip 23 being connected to the base portion 24 by a vertical section 25. The inner or rear end of this sliding bracket 22 is formed with a substantially vertical flange 26, this flange eingprovided, preferably near Vits upper end, with a threaded opening 27 adapted to engage the threads of an adjusting or tightening screw 28 which is mounted in an opening 29 in the vertical inner wall 12 of the stationary member 6. The base 24 of the bracket 22 is further provided with an elongated slot 30 through which a shouldered screw 31 passes, this screw being firmly mounted in a threaded opening 32 in the base flange 13 of the member 6.l A washer 33 is inserted between the head of the screw 31 and the base 24. It will be understood that the shoulder of the screw will be so selected with relation to the thickness of the bracket 22 and washer 33 as to provide an easy but accurate sliding fit for this bracket on the flange 13. The brackets 22 are relatively short in length and as many of these brackets are used as may be required to secure the necessary holding power. One of these brackets 22 is shown in a detached perspective View, Fig. 5.

Mounted on the flange 11. in the preferred form of my invention is a cover or semitrough shaped bar 34. 'This cover-bar is formed with a groove 35 adapted to frictionallyrengage the flange 11. The upper surface of this cover-bar is formed with an arcuate surface 36 which terminates in the edge 37.

This edge 37 is at a higher elevation than the balance of the bar when assembled as shown in Fig. 1, from which View it is evident that the cover-bar drains into the trough 9 at the lowermost point of the trough. This cover-bar 34 is clearly shown in the detached fragmentary perspective view, Fig. 6.

It will be evident from an inspection of Figures 3, 4, 5 and 6 that the elements used in this improved mounting are admirably adapted for production by the extrusion process. It will be understood that the brackets 22 illustrated in Figure 5 are readily cut from extruded bars. It will also be evident that the amountof machine work which must be performed on these bars is very small,

thus reducing fabrication costs to a minimum. It will also be apparent that the outer clamping member 15 has no openings, recesses or depressions in its face and is therefore easy to keep clean or polished.

The method of assembling and erecting this improved mounting is as follows:

The supporting member 6 is preferably prepared in the shop before shipment by cut ting to suitable length and by drilling the necessary drain holes 10 and fastening holes 7, and by drilling a series of holes 29 vin the vertical rear wall 12 of the stationary member 6 and drilling and tapping theholes 32 in the flange 13. The brackets 22 are then attached to the stationary member 6 by means of the shoulder screws `31, and the screws 27 are engaged with flange 26. This assembly, consisting of stationary member 6 with brackets 22 is then preferably shipped to the place of erection as an assembled unit. The outer clamping member 15 and the cover-bar 34 are likewise shipped to the place of erection.

In erection, the stationary member 6 is secured to the building frame in the desired location. The brackets 22 are then released by a rotation of the screws 27 in the proper direction until the sliding brackets occupy the positionv shown in Figure 7, access to the screws 27 being obtained through the opening 5 between the rea-r wall 12 of the stationary frame 6 and the display board 4, provided for this purpose. The screws 27 are provided with a hexagonal or other suitable head adapted to be rotated from above in case of the construction of Figures 1, 2 and 7, while flat-head screws 28El may be provided for the flat display window construction illustrated in Figure 8. The glass 1 is then put in place, being supported on Va plurality of wood blocks or other desirable supports which are not shown in the drawings as they are a common expedient well known to those skilled in this art. The outer clamping member 15 is then Aset in position as shown in the broken lines in Figure 7. The screws 27 are then rotated in the proper direction to draw the sliding bracket 22 inwardly until the outer clamping member 15 contacts the'glass 1 sufliciently tightly. The cover-barI 34 is then sprung or forcedV in place on the flange 11 to complete the mounting.

' In the event that a removal or renewal of the glass becomes necessary, the cover-bar 34 is removed and the tightening screws 28 are released until the outer clamping bar 15 can be lifted out, whereupon the glass can be removed.

It will be evident that the tightening bracket 22 is capable of slidable movement independently of the outer clamping member and it will be particularly clear that the bracket 22 can be moved to a position permitting-the outer clamping member to be removed without necessarilymoving this memmember 15', this lip 23 ber .away from the glass. This has the evident advantage that any one -or all of ;the brackets may be moved to the vreleased position without distorting the outer clamping member or causing any yundue strain either inthe glass or clamping member.

Referring now to the form of my invention illustrated in Figures 11 to 13 inclusive, which likewise shows .an application of this device to a store front construction, it will beapparent that the inner clamping member 6 and the cover-bar34 are identical with these members described above. rfIlhe outer-clamping member 15 and the sliding `brackets 22 differ slightly in this construction from the corresponding parts above described.

The outer clamping member v15 is formed with a lip 16 with a lower edge 17 adapted to contact the flange 13 of the stationary member 6. The intermediate portion 13 of this outer clamping member has a slightly different contour than that shown for the member 18. However, this forms no part of my invention and only indicates that various contours may be used with this type of mounting. to this intermediate portion of the clamping member is a reversed lip 19 which is connected to the intermediate-portion by a short vertical web 20. The drain recesses 21 are provided in the lower edge 17 of this clamping member 15. This outer clamping `member is similarly formed by extruding, as will be understood.

Mounted for sliding movement on the horizontal flange 13 of the stationary member is a bracket 22. This bracket is formed .at the left or outer endr with a reversed lip 23, adaptedto engage the reversedlip 19 on the being .connected to the base portion. 21lof the bracket 22 by a vert-ical section 25. The inner or rear end of this bracket is formed with a vertical flange 26', threaded opening 27 adapted to engageV the threads of an adjusting or tightening screw 28 and thebase 24 is provided with an elongated slot 30 in the same manner and for the same purpose as in bracket 22. It will be understood that these brackets 22 are preferably formed by cutting from a long bar of extruded metal and that as many of these brackets will be used as are necessary. One of these brackets 22 is clearly shown in perspective in Figure 12.

The method of erection of the members shown in Figures 11 to 13 inclusive is identica-lly the saine as that used for the structure shown in Figures 1 to 10 inclusive. Fig. 13 shows the sliding bracket in its released posi* tion and the outer clamping member in broken lines to show the ease with which this member may be put in place or removed.

It will be evident that the interlocking engagement of the reversed

lips

23 and 19 forms an arcuate surface of contact as shown adapted to contact the glass 1` Attached.

in Figure 11, while the corresponding contact in the structure shown in Figure 1 is of a wedge nature and it should be pointed out that these ytypes of contacting surfaces can be used interchangeably. The essential difference vbetween the invention illustrated in VFigures 1 to 10 inclusive and Figures 11 to 13 inclusive Iis that the resilience at the outer end of this mounting is provided in the vertical web member v2O in the first case and in the 4vertical arm 25 in .the second case.

Figure la shows 4the invention of Figures 11.1to 13 applied toa door frame 38, the only difference in the structure being such as may be made to satisfy the artistic ideas of the designer, the construction, operation and functions of the different members being substantially identical in both applications, no drain trough, however, being required. for the application tothe door, andan ogee wall 12a being substituted for the vertical wall 12. Outwardly extending flanges 39 are also formed on the stationary member 6a so as to provide suitable means for supporting this member on 4the-door frame 38.

Figure 15 is a modied form of the device illustrated in Figures 1 -to 10 inclusive and is shown principally -to show that the contour of the outer clamping member 15EL may be varied to a remarkable degree with my invention, and that web 20a supporting the reversed lip 19 is not limited to a vertical po sition.

In the mounting of glass windows, it is essential that the clamping means be resilient or yielding so as to eliminate unequal strains in the glass or local stresses on the glass which might cause fracture of the glass either in erection or in service due to the additional strains caused by the elements. In order to eliminate suchexcessive strains I provide the sliding brackets 22 with a relatively long flange 26 which is composed of resilient material and is so proportioned that the flange will yield or spring before excessive stresses can :be transmitted tothe edge of the glass by the screw 28 or byother agencies during service. In the form of device illustrated in Figures 11 to 14 inclusive, additional resilience is provided in the sliding bracket 22 by the substantially vertical arm 25. In the form of device illustrated in Figures 1 to 10 inclusive and Figure 15, additional resilience is provided by the relatively thin depending web 20. The thickness of this continuous web 2O is so selected that it will be substantially equal in resilience to the series of arms 25 on the brackets 22 of the form shown in Figures 11 to 14 inclusive, as will be understood. It will thus be apparent that I have provided resilient elements associated with this improved tightening device which will eliminate danger of fracture of the glass not only in erection but in service.

In connection with the tightening and releasing of the sliding bracket. 22, it should be noted that the registry of the screw 27 in the opening 28 and the Aengagement of the slot 25 with the shoulder screw 26 provides means for guiding the sliding bracket in adirection at right angles with the plane/of the glass.

It should also be noted that the screw 27 is exerting its force in a direction parallel to the resistance of the outer clamping member in all forms of this invention shown, and in the form illustratedin Figures 11 to 13 the screw exerts its `force not only parallel to, but in line with the point of application of the resistance ot the clampingV member to the sliding bracke This arrangement insures a minimum of frictional resistance in the tightening device, causing the force of the screw to be directly transmitted to the clamping member and thus rendering the device very sensitive to the touch whereby excessively tight clamping is avoided.

1t will be understood that the size of plate glass cannot be furnished to exact dimensions and that certain tolerance must be allowed. In order to accommodate oversize panes of glass, I have so arranged the parts of this mounting to clear a possible extension of the glass beyond expected limits. It will be clear from the drawings that the tightening screws are oi such length that they willnot intersect the plane of the glass. Likewise the two ends oi.I the sliding bracket are so' located and their movement so limited that the vertical projections at the ends of the sliding bracket do not intersect the plane of the glass in any position, and that the glass may extend substantially to the top of the base of the sliding bracket.Y

twill also be noted that the drawing force oi the tightening bracket is applied to the outer clamping member at a point between its upper edge which contacts the lass and its lower edge which contacts the ange of the stationary member, and in this manner the stress will be automatically distributed between the two contacting lines and will insure a water-tight joint at both places.

lt will also be evident that the shape of the reversed lip on the sliding bracket and the co-operating reversed lip on the outer clamping member will cause the outer clamping member to move toward the flange 13 of the stationary member 6 while the clamping member is drawn toward the glass. In the forms illustrated in Figures 1 to 10 inclusive, these two co-operating surfaces very deinitely are wedge surfaces. In the form illustrated in Figures 11 to 14 inclusive, the reversed lip on the sliding bracket is in the form of a bead while this reversed lip on the outer clamping member presents an arcuate suriface to the bead, these elements performing substantially the same service as thewedge surfaces but to a somewhat less extent. This tendency todraw the clamping member toward thelange 13 is especially advantageous for those cases where thereversed lip on the outer clamping member does not line up accurately with the recess formed under the rethe supporting member G. It is often impossible to select a regular spacing for these brackets. For instance, it is usually desirable to locate a bracket close to the end of the outer clamping member in order that this member may be accurately held at the joint which this clamping member makes with the adjacent clamping member. My invention lends itself readily to this variation in spacing as there is nothing on the outer clamping member which must, in any way, register with these sliding brackets at any one spacing, in other words, the outer clamping member without alteration, properly co-operates with the tightening devices regardless of the position of these devices on the stationary. member. This results in considerable economyof fabrication as it is not necessary to space the brackets accurately, and because no fabrication for connection process need be done on the outer clamping member. It should also be noted that those parts of the sliding brackets with whichthe outer clamping member must engage are in full view of the erector when he puts this member in place. This is a -decided advantage especially in erection, as compared with other mountings with which I am familiar as there are no threaded holes which must register with cert-ain openings to permit the insertion of screws and there are no extensions or projections which must be threaded under the glass to make engagement with certain elements which cannot be seen by the erector.

The cover-bar 34 serves a dual purpose. First it provides an enlarged draining ca# pacity without unduly enlarging the stationary member. This excess draining capacity is ofconsiderable importance when windows are washed and the drippings from the wiper run down in streams. The second purpose of this trough, of course, is to cover and completely conceal the adjacent screws so that a uniform and neat surface may be presented to the eye of the observer. The smooth surface formed by this combination trough, being free from obstructions, is easy to keep clean. i

It will also be evident from an inspection of Figures 7 and 13, that the outer clamping member in both forms of this invention is substantially supported at two points as soon as it is placed in position, iirst on its lower edge on the flange 13, and second at anintermediate point on the

bracket

22 or 22. This is an advantage in erection because there will be no tilting or slipping of these outer members during the tightening-operation as these members move inwardly in a straight horizontal motion in a stable position.
