METALLIC GLAZING.

.hpplication filed Kay 18, 1921. Serial No. 469,256.-

To all whom it may concern:

Be it known that I, WILLIAM HENnnRsoN, a citizen of Great Britain, resident in the Figure 3 is a city, county,and State of New York, have invented certain new and useful Improvements in Metallic Glazing, of which the following is a specification, reference being had to the accompanying drawings, illustrating particular embodiments of my invention.

This invention relates to window glazing, such as is sometimes referred to as leaded window panes, as for Gothic windows, and generally to glazing in which a window pane is made up of a nuinber of separate pieces of glass or in which the pane is subdivided b ledges or glazing bars. More particular y this invention relates to the glazing bars or ribs or ledges which subdivide the pieces of glass which are secured together to make up the complete window ane. p In building up the pane from a number of pieces it is an advantage and economy in work to have the glazing bars properly hold the pieces in position, and this 1nven-.

tion provides glazing bars to most effectively serve this purpose and at the same time effectively provide for holding the pieces in position and permit their being permanently secured in the completed frame and providing'for the required airtight joints. Among" the further objects of the invention are the provision of features of construction which permit the removal of a broken piece of glass and the replacement of a pane or a section of a pane without permanently marring or breaking the glazing bar, and accomplishing this repair of a window-quickly and economically.

In particular forms certain features of my invention are specially adapted to provide a frame that will fitthe sash, with or Without the sash top, providing a perfect joint with the sash, with concealed attaching means readily removable in emergency without destroying the parts or permanently marrin them.

Partlcular embodiments of my invention are shown in the accompanying drawings in which- Figure 1 is an elevation of a window sash with a Gothic divided pane.

Figure 2 is a cross-section of the glazing bar scale.

cross-section of the sash onv line 2-2 of Figure 1, on an enlargedframe and a side glazing bar on-line 33 of Figure-1, on an enlarged scale.

Figure 4- is a cross-sectional view of a sash side frame similar to Figure 3, but

modified to eliminate the necessity of an additional stop member on the sash or window frame.

Figure 5 is a cross-section of amodifi d form of glazing bar adapted to be used between adjacent pieces of the pane.

Flgure 6 is a fragmentary portion of a glazing bar in side elevation.

'Flgure 7 is a cross-section of the bar shown-in Figure 6, indicating in dotted lines difi'erent'positions of the pliable, securing ledges.

The window A has the sash frame B and the pane sections or pieces a, a supported by the glazing bars C. The sash frame member may be formed as shown in Fig. 3 and is preferably a drawn piece of zinc or copper or other-metals or alloys, such that standard sections may be formed with economy, and with stock construction the requi'redlengths can be cut with which to make up any size of sash., Likewise, the glazing bar used for the interior area of the pane can readily be drawn in the sectional form shown in Fig. 2 of zinc or copper or other material, as desired, and economically produced in lengths which can be ture.

In the sectional views the rib D on the double bar and the rib D on the side sash frame bar are formed as a stiff rib-member to give the glazing bar a rigid and permanent form on one side of'the pane. The sheet metal forming this rib continues in a bend E and a reverse bend section F forming a fixed ledge against which the rim of the glass rests. The sheet metal continues with a bend from this ledge F to a reverse bend section G in the forms shown of sash, sides, providing a pocket between the ledge F and leg G to fit the edge of the glass of the required thickness. As the leg G constitutes the edge of the sheet metal strip, it is pliable and may be bent as shown at G, permitting the insertion of the piece of the pane of glass as in the manner indicated in dotted lines in Fig. 3, and after insertion of the glass this pliable edge is bent down by hand and smoothed down by tool to a position firmly holding the glass against the ledge F, and thereafter the corner formed between the pliabie leg and the adj acent frame or other parts is fi led with putty to.provide a finished crevice, air-tight, and

closing the gap to prevent an accumulation.

I which brads such as k can be driven to hold to form the rib both the came or bar and the stop rigidly secured to the moulding of the window frame or sash, as'desired. The sheet metal edge beyond the leg J ma be turned, as shown, at jto form a finishe roll or heading, thereby stifiening the edge ,to preserve its form and finish, and roviding an overchanging crevice toassist 1n holding the putty finish. In the intermediate cames or bars, the form shown in 2 is drawn of sheet metal with the ridge and the two ledges F and F", the metal of the latter being bent beyond to form the pliable ledge G to clamp the opposite side of the rim of the glass. The metal from the ledge F is bent at right angles and extended to and bent double to from the rib L and the return bend Z is again bent at right angles so that the edge of the sheet forms the pliable ledge M, which is complementary to the ledge F, to form the pocket in which the adjacent glass rim is held. Both pliable rims or ledges G and M being formed as the two edges of the metallic strip constitutin a glazing bar and having no stiffening crimp or bend, are pliable so that they may be bent out of position sufficiently to permit the insertion of the edge of the glass section, without causing any distortion in the abutting or fixed ledges F, F" or the rib portions D or L. After the glass has been inserted the pliable edges or ledges G and M are bent down and peened or smoothed down by means of any convenient tool, forming a secure hold for the edge of the glass, and then the corners formed by them and the sides of the rib L suitably accommodate and hold the putty finish, as may be desired, with an assured uniformity in completing the glazing operation. In the side bar member shown in modified form in Fig. 4, the leg or face J is bent j with a right-angled bend doubled back to form a rib N, thus provid:

ing a stiff inside face adapted to fit into the mortice in the corner of the sash or window frame without the necessity of an additional stop. By this modification the strip constituting the came or bar has one ed e concealed. in. the finished structure whi e the other edge is on the member G, thereby providing the pliable ledge adapted to be bentout and in for the purposes of repair and replacement of broken pieces of the pane.

A. modified form shown in Fig. 5, has the rib D" in modified form with the desired stiffness but With symmetrical return bend sections F, the sheet metal then being bent at right angles to form the pocket for the rim of the glass and symmetrically bent in opposite directions in a close fold O on either slde and continuing in parallel sections P, P, one of which has its edge P bent into a head to form a stiff extremity to the rib and closing over the edge of the other side to form a finished structure adapted to maintain its shape in installation and use. The pliable ledges in this form comprising sections 0, 0 have their double bend closed tight,-

so that. with the suitable thickness of pliable "metal the two portions of the bend can be distorted without distorting the rib or stifi' portions of the bar or came to in any material way afiect the uniformity of the structure after repair or after the original assembly of the sectional bend.

As shown in Figs. 6 and 7, the pliable ledge G shown in dotted lines in distorted position G may be serrated as shown in the elevation, Fig. 6, so that each section can be bent up and back into clamping position with more facility and evenness. As so made, the many edges of a serrated pliable ledge provide additional holding crevices for putty which is later applied to finish the job. These sectional or serrated portions of the pliable ledge on the glazing bar may be of many forms and may be in the form of a few prongs or may constitute half or.

more of the length of the ledge. Being integrally formed with the sheet metal, they are readily made and form a strong-and permanent means of attachment of the edge of the glass and may be bent in and out for purposes of repair to any extent that may be required in usual or in extreme cases where the facilities for replacement or repair are required.

It will thus be seen that the side frame and the sash or window pane can be secured at one corner and an adjacent section of glass pushed into position snugly fitting into the pocket formed by the fixed edge and the pliable edge and an improved bar or came is then placed over the other edge of the glass section and on its opposite side the next piece of glass is inserted, with a further section of the glazing bar placed in position, until all sections of bar and ticularly at the joints of the glazing bars, 7

lass are in their roper position, and-'dur mg the operation t is im roved glazing bar provides for securely ho ding the sections, thereb greatly facilitating the assembly of lea ed panes or the operation of assembling Gothic window glazing and minimizes the chance of breakage and assures protection in roducing the finished pane or win v hen all parts have been assembled,

dow. the corners and ]0lI1tS of the metallic side members and intermediate lazing bars are connected by solderin in t e usual way or as may be otherwise esired.

In the case of breakage, the splinters-are removed from the broken section and the pliable ledge quickly bent back to clear the edge of a new piece of glass WhlCll is :inserted without straining the glazing bar or frame or without distorting and marring the finish and appearance of the rlbs or bars, and when inserted the pliable ledge 1s bent into holding position and, where desired, the puttyfinish is added, completing the operation-with reat economy and perfection. In form s own, as for example, in Fig. 5, the securing can be efi'ected leaving the pane in perfectly finished condition without the addition of putty, while and by iuterlocking the same b perforations in'one member, penetrated by the bar passing through the transverse member, or

m man other ways.

By t e use of the invention heretofore described, it will, thus, be seen that this glazing bar involves a weatherproof structure,

all seams being covered or blind, none bestill providing a finished and neat appearance, both air-tight and without objectionable crevices for the accumulation of dirt and without leaving any ragged edges to the came or bar.

The various sections of glazing bar can be readily drawn from sheet metal of a n desired thickness necessary to provide r1g1 ity andstill leave pliable the ledge or ledges which it is desired to distort for purposes heretofore set forth.

The folds of the metal constituting a rib on one side may be" so arranged as to permit the insertion of astraight or other suitable strip of metalwhen the glazing bars have been assembled or when the window has been completely assembled, thereby providing' a stiffening of the structure. This may likewise accommodate a stiffener bar,

as, for example, a steel rod; thus, the steel rods 01, barszlet into or passed. into theglazw ing bars of special conformation heretofore described, serve to give great rigidity to the window and may furthermore be interlocked to increase the structural advantage. Such bars may also serve by insertion to spread the parts of the pliable came or glazing bar after the glass has been positioned, thereby taking up any slack in the pockets which.

might exist owing to clearance necessary for its original insertion. v S'uch bars or rods may be varied by insertlon of sections, paring exposed to permit the entrance of the elements, which likewise applies when the stiffening bars are inserted inside of the speciall formed glazing bar, thus preserving a urable and uniformly lasting exterior, irrespective of any possible rusting that might be involved in the use of steel or other interior metal, which however is pro: tected against the weather.

The various forms of this article of manufacture in its main features involve the sheetmetal strip with the different ledges, legs and ribs formed by drawing it through a die but with such ledg s or legs and pliable headings integral wit the main portion of the structure.-

The -resulting .article of manufacture lends itself to various modifications based on engineering considerations and, in particular, in conformation to all the artistic requirements of windows of the class for which this is intended.

With respect to the question of fire resistance, the weakening or partial destruction of zinc or other metals having a low melting temperature, it will be seen that the supplementing or modification by adding the interior bars or rods, permits the use of steel of relatively great heat resistance, thereby providing a window that will withstand the effects of fire to a far greater extent, besides providing the strengthening heretofore mentioned, to resist greater wind pressures.
