Dec. 26, 1933- w. HENDERSON LEADED WINDOW TRUSSED JOINT Filed April 2, 1932 INVENTOR William Henderson ATTORNEY Patented Dec. 26, 1933 UNITED STATES OFFICE f.

Thisinvention relates to leaded windows, and more particularly to the construction of the joints, that is the inter-sections of the lead cames which hold the 'manysmall panes that are out of contact with the outer frame of the window sash or muntin.

The object is to provide for a more economical construction with respect to the assembly of the window as a whole, and to provide uniform strength at all joints,and in particularthe invention applies to what is known in the art as diamond pattern leaded glass windows.

In the accompanying drawing a specific embodiment of my invention is shown in a diamond pattern leaded glass window,'in which: Fig. I is an elevation of a complete window frame.

Fig. II is an elevation, on an enlarged scale,

of a joint showing the construction at the intersection of two of the came or glass-holding members.

Fig. III is a section on line 3--3 of Fig. II, on an enlarged scale, showing in more detail the internal construction at a typical joint.

Fig. IV is a section, part perspectiveof a staybar came joint.

In this embodiment the frame or muntins A surround the window section which is sub-divided into a large-number of diamond shaped n panes which may be plain or stained glass in any.

usual desired character. These glass sections are held by cames of which B-B-B are each of a length spanning one intersection, thatis nor-- dering four of the diamond shaped glasspanes.-

joints" at the middle of oneof the came members B to the muntin. Thus the entire area of the window section, except around the'edge adjacent the muntin, has the individual diamond panes supported by cames which in every case extend through one of the inter-sections, and

therefore form what may be termed atrussed.

joint.

The cames used for thisconstruction have the erably of a width exactly equal-to the spacebe-- tween the inside surfaces of the leaves of the came, so that at each joint the laterally abutting The came sections C --CC are half or less the length of came members B, and extend from came section will have its bordering reinforcing bar fit snugly between the leaves of the continuous came'member at the intersection or joint, and abut tightly. against the sides of the lead of the heart. 1 V v Thus in Figspll and III, ,bar B is-continuous with its reinforced steel insert through the joint, and came B abuts oneside, while came C abuts the other side of the'joint or intersection, while I the glass panesD*-DD fitinto the camesat 5 thejoint corners. Each of the came sections having. the reinforced strip E, it will be seen that came section B has the reinforcing continuous through the joint, and .by the arrangement, as described in Fig. I, every joint in the window has one double-pane length came continuous through the joint. In addition, itwill benoted that at each intersection or joint the continuous double pane length came 'is'in oppositedirection. Thus each joint is spannedby adouble panelength came, which in turn is supported at its ends at themiddle ofanother similar length of came at its middle where it joins at the intersection abut tingthe contiguous reinforcing bar in the heart of the other came section, so

In this way an entire Window is'made up of came sections equal to thelength of two panes, the lead came with its socket being readily'cut to this uniform length, and the reinforcing strips being cut to their uniform exact length,--thus 35 giving only one length of came and one length of reinforcing bar for the purpose of the entire assembly of the pane, except for the few short border sections abutting the muntin or frame of l the window. "This means that'the assembly of such a window. is made by the glaz'ier with uni: form length" cames with the leadeasily out to 7 length, and'into which the separately cut-tolength fiat strips are inserted by the 'glazierand'with' those reinforced came sections the entire window is assembled with the glass panes,

with the greatest simplicity and economy It will be seen, furthermore; that the leaves 'of the cames bordering each pane register sothat the 0 glass panes D fit into the corners formedby the intersecting cames at the weatherproof'j'oint'and as each came bordering each glass has the 'reinforcing bar-reaching tothejunction of the intersection, a rigid came support is. assured, along all sides-of the glass panes, thereby assuring the much desired strength that provides for durabil- 'ity in .windows of thisstype. On account of such combination in the construction, the required strength of the window is attained without the necessity of outside staybars, or any of the other devices heretofore employed.

The section of joint, Fig. III, shows how the came B has the lead portion cut away near the end with the protruding stiff bar end E closely fitting into, that is between the leaves 11-1) of the came member B. So soon as assembled with the panes, that is the individual glass sections,

the abutting end of the leaves cc are soldered as at F, to the edge of the leaves b-b, and likewise the abutting ends of the leaves b are sol dered to the edge of the leaves 12-17 of the truss length B came forming the lateral supporting member for that joint. This soldering need in no way touch the glass, but immediately creates an integral joint as far as the lead came leaves are concerned, thereby holding each abutting came member with its reinforcing strip in its core permanently into the socket formed by the truss-length came at that joint.

' It will be noted that the lead came with its pocket can be cut in uniform lengths with the exact bevel desired for the needs, as required for 5 the particular design of the diamond pattern of forcements can be made very economically, and

in fact the ends can be finished if desired in order to make the desired accurate fit at the point, of their engagement with the side of the lead bar between its leaves when being assembled.

It will also be noted that the advantages incident to this invention, are not dependent upon the exact diamond pattern or its angularity, and

that rectangular patterns may be .built up with similar advantages in production and strength of the finished window; Should the patterns be oblong, or if in any way the sides of panes are of uneven length,-though uniform throughout the window, it would only mean two uniform lengths of came sections and reinforcing strip sections,

' still' providing the economy in production and assuring the advantages in uniform finish and strength of the assembled window;

A modified form of the invention is shown in apart perspective sectional view of a joint, Fig. IV, in which each of the cames is of staybar construction. This is illustrated with respect to applicants invention of a protected staybar set forth in his pending United States application Serial No. 406,546, issued Patent No. 1,858,775. It may be desirable in certain cases to use cames of applicant s staybar construction form, in which the staybar, instead oof a small reinforcing in a came heart, protrudes far above the leaves on one side of the came and as an integral lead casing forming a considerable protrusion on that side of the came. 'As illustrated in Fig. IV, the inter section when using such encasing came staybar structure, requires modification at the joint. Thus the staybar His cut down at 1-1 so that the end of the staybar ends between the leaves L and M of the intersecting came member G. As shown, the similar members G and G are joined at the intersection, and the integral casing. J on the member G and G are cut away so asto' permit the restricted end H of the staybar H to fit the joint, while the lead portion of G and G are pinched as at K, around the beveled portion h of the staybar H, so as to enclose the staybar and make the seal weatherproof, with. the soldering O at the junction between the lead of the lateral cames with the leaves LL of came G. The staybar H is so cut as to permit its end H to enter and abut the heart end of the came G, and the lead on its sides may also enter between the leaves, so that the pane inserted between the leaves of the intersecting cames will be closely enclosed with lead at its corners.

It will thus be seen that should staybar enclosed cames be desired for this type of window the intersecting I joints may be completely weatherproof and in the assembly of the window the staybars, such as I-I--H on the lateral cames,

abutting the joint, may be cut and fashioned entirely separate from the lead portion of the staybar came. Likewise, the lead portion of the cames may be so cut to length as. to provide for the insertion of the pre-cut staybar section, so that the assembly will be quick and economical, and still provide for all necessary soldering without the chance of cracking the glass, and with convenience for soldering and manipulating the lead casings during the assembly, without any. difficulty whatsoever.

Various other modifications may be made in the practice of my invention, and it must be noted that among the variations my invention lends itself to form the joints with the lead leaves overlapping so that they provide an appreciable surface contact for soldering them together. Thus the members C and B, in Fig. II, may have the lead extend the same lengthas the reinforcing E, and the leaf or leavcs'b-Ja, may be easily spread where thelateral cames abut, and after spreading them may, be bent down toform an appreciable surface contact withthe top of the lead leaves of the abutting cam ends. The leaves of the lateralcame sectionsmay also be slightly beveled in order that the came'and its reinforcement shall fit snugly between the leaves on the through section of came, and still'assure thereinforcing end substantially abuttingthe heart of the throughcame. i

In the case of staybar construction in which one leaf on each side extends from the middle of the staybar pocket casing, a further modification may include an incision in those leaves, so that the laterally abutting reinforced staybar came is let into the through section of came to a sufficient extent for the staybar end of full breadth to abut against the heart of the through member and against the entire casing of that member which surrounds its staybar portion. Such form permits the casings of both through and abutting came sections to be on the same level, and ihe adjacent ends of the lead leaves may be bent to the glazing of windows-in accordance with my invention. It will also be noted that when an encased staybar came is'used with its'leaf projecting from the side, and not. from the top and bottom of the heart, I may, if desired, cut the end of the staybar sections with a notch, instead ofbeveling them as in Fig. IV, and in so doing I preserve the full width of the lateral camesections to abut the entire casing of the through came section, with the lead leaves suitably pried or bent and peened to finish the joint. This is particularly practical in view of my staybar cames being formed so that the staybar may be inserted after the lead came has been cut to length, so that the machining of the hard metal may be done separately just as conveniently as cutting it to length. Various other modifications may be made without departing from my invention, but what I claim and desire to secure by Letters Patent is:
