GLASS-SECURING- DEVICE.

Application filed .Tuly 30, 1917.

To all whom t may concern.'

Be it known that I, DANIEL J. lliunNANn, a citizen of the United States, residing at Chicago Heights, in the county oi Cook and State of Illinois, have invented new and useful Improvements in Gl`ass-Securing Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to glass securing devices, and more particularly to settings for plate glass such as are commonly used in store fronts.

One of the objects oi my invention is to provide an improved skeleton sash or setting for the glass to take the place of the usual solid bronze or metal sash or setting but which will look like such a solid sashv and pi'esent an appearance equally as good, and be as durable and lasting in use, besides having the advantage of drainage, it desired, to take care of the water oi condensation. Additional advantages and objects are ein treme simplicity and cheapness ot manufacture, ease of installation, and the use of a minimum amount oi' material while at the same time affording a sate, solid and rigid support for the glass. ik further object is to provide a setting of this class in which the depth oit the rabbet is greater than is ordinarily possible in settingso't this class, thus permitting the glass-supporting ineinbers to engage the glass at a greater distanceV Yfrom the edge of the plate and thereby ai# fording a better and more secure support for the glass. till another object is to provide a construction in which there can be no undue pressure on the glass adjacent the securing screws or elsewhere, in which there is no pinching of the glass or strainrdue to direct screw pressure at the holding screw points, whereby liabilityT to breakage is avoided, and which may be installed by any competent glazier without special skill, training or care, and without breakage of the glass.

In the drawings, in which l. have shown one form of my invention- Figure l is a perspective view showing the lower edge of the plate glass, the windowsill, and the setting tor the plate glass 5 Fig. 2 is a plan view or" the same ,n Fis. 3 is a cross-section on the line 3-8 of Fig. 2;

Specification of Letters Patent.

Serial No. 183,487.

l is a perspective view oi' one of the rigid supports ot the outer member; andv Fig. 5 is a similar view oi' one oi' the supporting brackets of the inner member.

Referring to the drawing in detail, the setting shown comprises the inner supporting member 10,secured to the riser 1l `for supporting the inner side oin the plate glass l2, and the outer supporting member, molding o r stop 13 secured to the sill 11i and supporting-the outer side oi the plate glass l2. Y The inner member l0 comprises a thin sheet metal channel member 'l5 extending throughout the length oi the edge of the glass, and a plurality oi supporting brackets lhoused by the channel irfeniber and placed therein at frequent intervals, say, every ten inches, and supporting and reinforcing it against pressure *from the plate glass. T he brackets 16 may be secured in the channel member l5 in any suitable manner, as by striking projections l? from the channel member l5 into the ends of the tubular' portions 18 of the bracket lo. The tubular portions are ot such length as to completely Vspan the space across between the edge flanges of the channel 16, and the punchedin portions 17 grip the edges of the tubular portions i8, thereby preventing displacenient of the brackets themselves and in tuin preventing the said flanges from loosening and springing away from the ends ci the tubular portions. The whole forms a rigid inner support vfor the glass plate. Y

rlhe outer supporting member or stop 13 is oit skeleton construction and comprises the sheet metal channel member 20, forming a molding, and a plurality ot supports 21 housed by the channel member and placed at frequent intervals, say, every ten inches, throughout its length, 'for supporting it in an upright position like a solid stop and iler sustaining` and reinforcing the channel niember not only against the pressure oi2 the screws 22, which secure the clamping means to the sill la, but also to make ita solid and rigid support for the glass.

' The channel member' 2O has an inwardly extending flange 23, bearing on the sill lil, on which one leg 24 of the support 2l bears, and also has a downwardly extending flange 25 for engaging the plate glass l2, the support 21 being sprung into position in the channel and held in place between the flanges 23 and 25 (Figs. l and 3l.

all

vshaped to receive U liange of the inner channel member.

The support 2l is positioned and retained lengthwise within the channelY member by means of a countersunk portion 26 on the channel member, which is pressed into the opening 27 oit the support 2l afterV it is in position.

the conical head, of the screw 22. Y

r he Vsupport 2l is provided with a downwardly extending leg 2S) which bears on the sill let, thus holding the channel in upright position on the sill or frame. The bearing portion ot the support 2l adjacent the countersunk portion 26 of the channel member 20 lirmiy supports and sustains the channel member against buckling duc to the pressure of the screw 22,- 'and the legs 24- and 29 limit the distance to whichthe screw can be driven intoY the sill.

ylhe support 2l is preferably formed and stamped of a single piece ot sheet metal which may be so stamped as to provide stili cning webs 3l to prevent collapse or' the support under the pressure oi' the screw.

The sill is covered with a sheet metal molding 32 extending down over the front edge of the sill and back under the glass and upwardly along the riser to the point 33, slightly beneath the lower edge of the This sill covering is provided with slots 28 to receive the screws 22, formed by punching up thermetal to form the flanges 34,'the

' slots affording room foradjustment in position, both laterally and longitudinally,ot

the screws 22', and therefore the outer member 13, to accommodate dill'erent thicknesses oi glass or a dili'erent endwise position, and the flanges 34; preventing the entrance of drainage water into said slots.

4Drainage of the water ot condensation from the inside ol the glass, it' desired, and

' also ventilation to the extent permitted by l the drainage apertures, may be provided by the holes or slots 35, in any desired number, formed in the outer edge wall of the member i3, and the corresponding holes or slots 86 formed in the horizontal web ot the inner channel'member l0.

The same, or asimilar construction, can be used for the side and top edges ol the plate glass, except that in such cases the sill covering 32 would ordinarily not be employed, the screws22 for the side and top setting being screwed into the window frame.

InV use, the inner member l0 is secured tothe riser 1l, or other suitable portion ot theswindow frame, by means of thenails or yscrews 3.9,.andthe plate glass l2 is set up against the inner clamping member, its lower edge resting on two setting blocks, one near each vertical edge,.as is common. Owing to the fact that there are no screws or other clamping parts of the structure between the This countersunr portion 26 is'v edge 0l the glass and the sill covering, these setting blocks may be low or thin, and ordinarily are just a piece of 'heavy or sole leather all. The outer member 13 is then set onthe sill and pushed up by the hand against theA plate glass l2 and the screws 22 are inserted through the openings 2G in the channel member 20 and the slots in the sill covering and screwed into the sill let orl other suitable portion of the window frame. rihe supports 21 serve to support thestop 2O in uprightposition on the sill or trame both bei'ore being moved into position or fastened, as well as after, similar to an ordinary solid stop or quarter-round, and to support the outer taceV of the glass, .and they take practically all ofthe strain due to the screws 22, thus preventing buckling or dcf- Y ormation .-ol" the channel 20. Any ordinary glazier can do this without special skill or experience with. the particular setting bei cause it is merely necessary to bring the stop up closely to the glass and drive the screws home. There is no danger of pinching the glass yby'tightening these screws, as might be the case if the screws extended horizontally past the edge of the glass into the baclr riser and thus by direct screw pressure put a strain on the glassV at these screw points of contact. Although the leg 2e bears directly on the flange 23, it also bears indirectly on the sill 14, the pressure being transmitted through the flange 23. The drawn sheet copper of which the outer molding 13 or channel 2O is prete ably made can thus be oi light gage material, due to the presence of the rigid supports 2l, and forms as a whole a strong, rigid support, molding or stop for the outer side of the glass. rllhe same is true of the inner member. A saving of sheet material in the outer stop is effected also, because of theslight depth of flanges 23 and 25 required, and also the comparatively low height of the setting from thesill'or jamb, due to the absence ol' all screws or other clamping mechanism between the edge ot the glass and sill. The inner member l() is also preferably made of drawn sheet copper, which is. particularly desirable in glass settings because of its lasting quality and its inherent smoothness and'softness as a grip for the glass. lt may, however, be oi? wood or any other desired typeot construction. Y Various modicationsand changes may be made without departing from the inventionY as set forth inthe appended claims.

Having thus described my invention, what l claim as new and desire -to secure'by Letters Patent is- Y l.' In a window glass setting, a stop for one `side edge of the glass constructed to be secured to the 'tace of the sill or frame which is adjacent to the edge of the glass and substantially perpendicular to the plane there- Ulf) ot, said stop comprising a thin sheet metal channel strip :toi-ming a. molding, supports plared at AFrequent intervals within `said molding to sustain the same in upright position en the sill or traine, and having a hearing portion in contant with the wall ot the molding to support the saine against pressure toward the sill or, trame, and securing means passing through said molding and supports and into the sill or iframe.
