TJQAH'BR'QGDEN, OF PHILADELPHIA, PENNSYLVANIA, asstonon T0 DAVID narrows SONS COMPANY, or IfHIL-ADELPHIA, PENNSYLVANIA, A. CORPORATION or PENN- SYLVANIA.

To all whom'it may concern: a Be it known that I, Joan BRoooeN, ot Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented,

a skylight bar within whiclrthe panes are so mounted as to rest on'strong U-shaped packed supporting members upon which the panes are maintained by a water-tight connection without the use of putty. For this -purpose I eniplo v a trough-shaped structural barmade of heavy sheet metal with grooved wingsintegral with the edges thercof, which provide the means for niaintaining the packing material. The other mem- .ber consists of a lighter and more flexible metallic cap provided with corresponding grooved wings for packing materials. 'lhe two members are united bynucans which i adjust-ably maintain thcm'in proper relation to each other, the cap portion by reason of its thinnerstructure supplying the elasticity to control and permit the adjustment of the pressure between the parts, necessary to compensate for that flattening of the packing which time produces. The m ans or uniting the 'cap member to the bar are swiveled at the sides of the latter, instead of being fastened. to the bottom of the trough-shaped bar. which latter construction is objectionable because it involves piercing the bottom of the trough, thus atl'ording a'possibility of leakage of the drip. The swiveled construction atl'ords the further advantage that when, the bar is packed for transportation. the unitingmeans F maybe turned down within the bar from its projecting position, so that it is not likely to be broken ofi.

edges with two lateral wings 2, and 3.

shaped into semicircular grooves for the purpose of holding the packing material l, such as oakums The bar with its wings is rolled from a single sheet of metal.

At intervals along the length of the skylight bar swivt-led bolts 13,, are located. Each bolt is provided with a stud or rivet 7. on one side 8, which passes through one side only of the body portion l. of the skylight bar, and'is headed over sutlicientl) to maintain the bolt in position. The lower end of the bolt 6, is provided on the other side with a ,fi'itlltlll extension J, adapted to conform to the interior contour of the body portion lyof the skylight bar. thus aiding to maintain the bolt "in its upright position, although the body is pierced onlyonce for each bolt. The upper end 10,. of the bolt (3,

is screw threaded to receive the nu? ll. by

means of whirl. the cap memb r 1;. is held in position. The bolts 6, arc-swivelcd to the body portion .1, so that they may be turned joint formed by two overlapping panes, and

bottom of the trough shaped bar along which the drip passes, through which leakage might occur, and also of preventing the bending of projecting parts during trans? por'tation. 1

The cap member 12, is formed of sheet metal much thinner than the body portion and in the-shape of an inverted trough or arch. more shallow than the body member, having lateral wings Li, and to, which are formed into semi-circular gt'-. o\es for the purpose of holding packing material 16, in proper position against the upper snriaceof the panes 17. Thus the grooves formed in the wings of the cap member are opposed to the grooves formed in the wings of the body member, and when the two are screwed down together by means of the nut 11, a perfectly water-tight joint may be prod ced without. the useof putty. 'lihe comparativclv flat, angle ofthe wings of the cap member, and

-pancs in position against the packing nuttheir thinner Structure, renders'thcin sufficiently elastic to permit-jot an adjustment of the pressure between the parts by screwing down the nut 11, whenever the flattening"; of the packing material by reason. of age renders such increased pressure desirable.

The body portion of the. skylight ar may be ofl'set at intervals, asat 2o. dq e mtin c", upon the length of the pane which in-lit I supported by the bar. As een in Fig. l, the t pane 17, rests upon the packing contained in the wings 2, and 3, of the section 21. ot' the body portion. The pane 1S, restssimilarly upon the packing material in the section 2;. f of said body portion, and these two sections 21, and22, are ott'setwith relation to 0m another sutliciently to allow the pane 18, to overlap -the panel! 7, and also provide for a strip of packing material 24. By reference. to Fig. 1V, it will be seen that this packing is inclined from the center toward each edge t of the )ane so that any water of condensatien col ecting on the under side of the pane 18, will trickle down upon the upper side of the pane 1i, and encounter the water shed formed by thepacking 24, and be detlectcd to each side into the gutters formed by the body portion 1, at the skylight; bar.

The cap 12, extends over the contiguous edges of the panes 1?. and maintains these terial. The cap 2o, extends over the contigttoils edges of thepanes l8. aml overlaps the cal 12, as shown in Fig. l. The lower end 27, of the ca p 26, is bent downwardly to meet the upper surface of the cap t2; Thus the moisture on the outside of llle't'til) 26, is

transmitted to the overlapping panes or to the outer side-of the cap member 1;.

As shown in the drawings, the skylight bars are secured to their purlins 30, and 31, by means of metal -clips 3-2, and 33, which are bent to include the purlins and are secured to the sides of the body portion of the bar, but any other suitable means of securing the bar to its supporting member may be employed.

The joint between the overlapping ends of the panes may be rendered water tight by means of a. strip of lead bent into a suitable form and placed between the overlapping faces of said panes in place of the oakum strip 24, indicated in the drawings.

By the constrtu-tion above set forth the. skylight. is rendered absolutely water tight withoutthe use of putty, which tends to harden and deteriorate with age.

Having tints described my invention, I claim: t

I. ma skylight support. the combination with an integral U-shaped supporting bar havin along each edge a laterally extending wing which is formed integral with the body portion of the bar. each of said wings having a recess facing the part to be supported, and adapted to receive a packing the snppo:

material, a sheet metal cap in the form of art inverted arch and means for adjustably securmgsatd capto said supporting bar.

2. in a skylight support, the combination having a recess facing the part tobe sup orted. and adapted to receive a packing 5 material. a sheet. time?! cap in theforin of an 'invcrted arch, having laterally projecting portion formed integral therewith, each of aid laterally projecting portions having a recess tacmg the part to bcsupported, and located substantially over the recess formed 5 in the supporting bar, said recess in said metal cap being adapted to receive a packing, and means for atljnstabiy securing said -ap to said supporting bar.

3. In a skylight support, an integral L'- shaped Stllilitil'tllig bar made of such proportions :t o form the sole support for the members to be supported. said supporting bar being provided along each edgewith integral wings having a recess in their npper taccs for the reception of a packing 1113- terial. a sheet metal cap arched in cross section and so proportioned as, to yieldingly clamp tin-members to said supporting bar, said cap having laterally projecting portions provided with a recess facing the members to be supported, said recess in the cap beingsubstantially ovcrv the recess in ling bar, and said recesses being adap ed to receive a packing material and means for adjnstably securing the sheet metal cap to said supporting body portion.

4-. In a sky light bar. a supporting member substmnially U- aped in c oss section, an arched cap member, a uniting bolt swiveled to one of the sides of the U-sha ed supporting niem cr, and provided on its opposite side with an extension for t'rictional engagement with the oppo ite side of the body of said supporting member.

5). In a skylight bar. a sup mrting member which is snbstantiall U-shaped in cross section. a uniting'bolt swiveled to ne side of the U-shapcd supporting member, and

provided at its opposite side. with a cotnpa ativcly narrow extension which engages the opposite side of said supporting member. and the bottotn thereof. wherelw the friction of the extension on the bottom of the supporting member. maintains said linlt erect.

In testimony whereof. I have hereunto signed my nznne. at litihnlclphia. Pennsylvania, this t\\"ent third day of Decem er not.
