' cheapncss, strength, and durability, combined with facilityof glazing and rcglazipg, also, to effectually provide against leakage from any cause.

The nature thereof consists in'the peculiar formation of the bar or rafter of which the skeleton of the skylight or other structure is This bar, or rafter I construct mainly of sheet metal, such as galvanized iron.

It is provided with ledges to receive the glass plates and sustain th'enn it has aiverticai two halves, so that an undercappingportion central portion, from which the ledges extend laterally at the upper part, and I fornrof the same sheetat its lower part gutters to collect and carry oil the water of condensation and leakage. So far this bar or rafter is composed of one piece of sheet metalfolded upward as is formed of the same piece and no joint ex posed below, and thereby all leakage between the two halves or sides entirely 'g n*e e'ntcd; The glasssupporting ledges, vertical central portion,and gutters ofthe above-described bar are intended to be located below the glass plates and form the skeleton of the sash or skylight, and must be of arnaterial possessing sufiicient stiffness and strength for sustaining the weight of glass which this part of the bar is intended to carry and support. Next, for the purpose of securing the glass plates to the bar or rafter, I add to the same a dcviccinadc of pliable, ductile, or flexible metal--such as lead or copperformcd into shape sectionall y like a letter Y, it having a stern and two up wardly-sprcading flanges or wcbs,each of single thickness of metal, and the three parts forming a triplicate of webs. The stem or lower web, for the purpose of attachment to the bar or ral'ter oi'vrigid mctal,is given SOlllC- what greater width or depth than the others. The thickness of metal in the upper webs must be confined to that which will pcrinitoi'reudy bending. That of the lower web is not so lllfltt plates to skylight bars or raftcrss rial. The stem or lower web is placed down be tween thatwo sides, forini ng the vertical central portion of the part of the bar below the glasssuppoitlng ledges to a proper distance, and

thereto secured by any suitable means, so that it forms, when in combination therewith, an

upward or outward continuation thcrcofinnd,

passing between the edges of the glass plates,

, has its upward branching webs above the glass plates. No part of this device is of doubled metal, and. the flanges or upper webs,

when in a structure al'ter glazing, beingof pli--'.

able or flexible material, are adapted to be readily and with easy facility pressed downward flat upon the glass plates, covering the joints between the edges of the glassand the stem or lower web, and thereby securing the vVhen rcglazingis necessa'ry, ,rhe flanges ,ur weiisnnay hereauny same against leakage.

bent upward to their first position, allowing removal of glass and placing of new. The

.webs are again bent or flattened downward to secure the joint as before. The pliable material thus used admits of its being pressed tightly'upon the glass, fitting closely into any inequalities of the upper surface thereof, and rei-idering the joint water-proof without the intervention of putty. I r

vThe invention further consists i n the tripar titc capping device as a means ofsecu "gig glass glazed roofs, and at thesame time securing thejoints.

against leakage, while permitting of ready repairs to the glazing. The combination ofth-ree webs or parts, as hereinbefore described, renders it'peculiarly adaptable to secure those r'esuits.

This dcviee is inade in long length,

and may be sold in that-form to the trade and by the buyer cut to suit his length of bar. It is not intended as a support, nor is it susceptible of such use.

I am aware that lead sash-bars have been used in stained-glass windows for churches, &c., but of such formation as to constitute grooves each side for the reception of the edges of the glass plates. An H shaped bar placed sidewisc is very old as a supporting-bar alone. Such would not answer the purpose for which this invention is adapted, nor secure the results obtainable from the peculiarconstruction of this device. \Vhcrevcr lead barshare been used heretofore to support the glass, they had to be formed with lower flanges or portions as a bed for the plates, and were not formed with a stem susceptible of attachmentto a rigid bar 5 giving the support.

Pliable cap plates formed of sheet metal doubled together are diflicult of operation. They cannot be dressed or properly flattened down upon the glass plates, fitting thereto,

, 10, without their breaking. They are also double the expense, and, being of necessity of lead orsoftcopper, they are comparatively. more costly, owing to the extra amount of material used. Pliable cap-plates formed of sheet met-v a1 doubled where they come in contact with ing the water to the leaky points.

-the vertical portion of the skylight-bar and at the points where they are riveted proved defective through leakage, the doubling up of the cap forming a trough 'or gutter conductthe double-thickness is a Waste of material. In consequence of these difliculties pliable caps have riot heretofore come into use.

Fig. 2 is avertical section of the-capping device of pliable or flexible meta]. Fig. 3 is a vertical section of the two parts in combination, illustrating their condition previous to glazing.

I 'down over the glass after glazing to hold the glass plates to the supporting-bar and protect the joints against leakage.

The rigidity of the metal, aided by its shape and construction in the snppcrting-bar or rafter, rendersit effectual. in sustaining the glass. as'shown at f f.

Besides,

The flexibility or pliability of the capping device, together with its peculiar formation into triplicate webs, renders it effectual as a means for securing jointswhen glazed and facilitating reglazing whennecessary.

The two parts of the bar are secured together by rivets or any suitable means, so that i when combined they are as one.

The triplicate capping device may be ap-.

plied to other bars forsupporting glass plates, entering into combination therewith to efl'ectuate the same results. It therefore may be made up in quantities and sold to the trade as an article of manufacture, to be applied by the buyers themselves to such other bars as they may desire.

' What I claim as new, and desire to secureby Letters Patent of the United States, is

A, skylight bar orrafter composed of two parts, A B, in combination, the supporting-bar A of one piece of sheet metal having rigiditysuch 8.3 galvanized iron-folded up ward to form gutters a a, vertical central portion, b, and lateral flanges c c, for reception of glass plates, the part B of pliable or flexible Inet-al--such as lead or copperin shape sectional-ly as a letter Y, with triplicate webs, each of single thickness-the one forming'stem. d secured to bar A in the vertical central portion, b, thereof, and the webs e e, adapted to be bent horizontally after glazing, substantially as shown and described.

2. A separately-constructed triple-web device of flexible or pliable metal, for securing joints in'glazin -'-one web, as a stem, adapted to be placed be ween joints to be secured thereby, and two other webs, branching iipward therefrom at suitable angles, adapted to be bent or flattened down over the joints for securing the plates and protecting the joints against leakage, in combination with a sheetmetal supporting-bar in skylights or glazed structures, essentially as shown and described.

3. The tripartite device Bofone thickness of pliable metal, having a stem-web, d, extending sufficient for attachment to a rigid sheetmetal supporting-bar (it being formed separately therefrom) for skylights and other glazed structures, and having two up wardbranching webs or flanges, e 0, adapted to be bent down over the joints after glazing sub- 'stantially as shown-and described.
