Application filed ll pril 10, 1917. Serial No. 161,051.

To all whom it may concern:

Be it known that I, AirrHUR E. RQQHDLE, a subject o1 the (ing of Great Britain, re

m v fl n srdnw at lhyla delphia Philadelphia. county, and tate of Pennsylvania, have inyetit'ed and discovermtcertain. new aliclusefpl Improvements il l sltyll h hts of which the following is a specification.

My said invention consists in certain improvements in the detailsof construction of skylights for buildings, particularly skylights of the type composed 0 glass and metal, all as will he hereinaften more any described and claimed.

Referring to the aecompar ying drawings. which areniade a part here'oi, ai d on which similar i-efer nce characters indicate similar pa t 7 i V Figure 1 is a view, partly i section and partly in elevation. through a portioil o a skylight constructed in a ocordanee with my sauliiitehtiOlh d i v i i a i Fig. 2a 'cross section on the dotted line 2-2 in Fig. 1.

In said drawings, the portions marked A represent the steel portions of the frame of the roof construction. to which the skylight bars are secured, B longitudinal skylight liars formed of chann ehirons, and. C the glass sections. mounted on the upper edges of said channel-iron supports.

Said glass sections C are fprmed with longitudinal corrugations in their top surfaces and are men ted on the top e' ges of the channel'Thars roller batrihgs 10, of lead ornther sui able materia beinginten posed between the top edgies'of and the under surface of t -e glass sections. Theseilead bearings are oylindl'iealiin form, as best shown in Fig. 2, having longitudinal openings in theirunder sides Ora width to permit an oscillatory niovem at on the edges 0 i the channel-irons when necessary, thereby lfliQlk tl lg tel me a-acme and expens ve Qt tie ramwwork and the vibratlon of the building. without danger of breaklng the glass.

Said glass sections are spaced apart substantially as shown in Fig. 2, and a cap bar 11 is mounted to cover the space between their adjacent edges. Said cap bars 11 are each of the form to provide depending edges, which are adapted to fit into or seat in the longitudinal grooves of the glass and thus form a tight join-L. As illustrated in Fig. 2,

l have shown these cap bars as roof-shaped in cross-section. Many modifications of this type of bar, however, will readily su gest themselvesto any competent builder of'arohitect, although'l deem the form shown as One especially well adapted for the pur pose. Said cap bars are held in pla'ceby clamping bolts 12, carried on cross-pins 19 and "projecting in a vertical direction through apertures in the top of said cap, and have nuts 13 on their upper ends, by which the parts may be tightly clamped together to form a water-tight and a weather tight joint between the glass and the chair neliro1 1 supports. The said ei'oss-pins ltl are an uIar'in cross-sectionfand the eyes of the clamping bolts 12 are of cor' respondin shape, sothat the pins. when put'in plat; for assenihling the parts, will stand and'be sup orted in an upright position and 'thu s faci itat'e thelplacing of the cap bars 11in position, as it will only be necessaryto siide the cap bars until the perforations therein register with the upper ends or the bolts, when they will fall m'toplac e, the bolts and the holes in the cap bars hem spaced uniform distances a part. The nuts 13 may then be adjusted. I have shownsaid cross-pins 19 and the eyes of the clamping bolts as diamond-shaped, but it will be understood that any other an ular shape ineross-section will accomplish t e same result.

Apother feature of my construction, to which I make special claim, is the channel.- shaped supporfll for the upper skylight bars interposed between'the mime-meats of t e metatarsal chanaeiamnae Said supportss'er've as supporting bi' ack ets and are of .channel or a Qle' shape," of the reqiiired length, *eorresponding substantially with the width of the skyli ht bar's. "These supports 14 are secured to t e i'o'oi 'constiuc tion by bolt 15. which boltf'also secures-the upper end of the lower skyli ht bar to the roof q 3 oi1struttion. while the bolt i6" secures thelbwer part of the upper skylight bar to said support. The ends of the channel.- iron supports are covered by metal caps 17 and 18, as shown.

The advantages of the several improvements in the skylight construction, which constitute my said invention, may be briefly recapitulated as follows: The edges of the cap bar, of whatever special form may be preferred, fitting into the deep grooves in the top surface of the glass, and being clamped therein by the clamping bolts, make a tight joint and render leakage impossible; the roller bearings, between the edges of the channel irons and the under surface of the glass, permit the contraction and expansion of the steel in the framework and also any vibration of the building, without transmitting the strain to the glass plates and causing breakage; the supports 14 enable a skylight to be constructed of a length greater than appropriate for a single pane of glass, by supporting succeeding sections in planes above each other, so that moisture, either on the inside or the outside of the upper panes of glass, will shed onto the pane below, and by supporting the clamping bolts on diamond-shaped cross-pins, as shown, or on pins of other appropriate angular form, they are supported rigidly in a position to receive the cap bars and thus facilitate the assembling of the parts.

While I have described my invention as an improvement in skylights and deem it particularly adapted for skylight construction, it will be understood, of course, that the invention may be utilized in window construction of other types, and that, for the purposes of the patent, the term skylight embraces any glass and metal structure wherein the invention may be appropriately used.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A skylight structure comprising a frame having supporting edges, lass plates with longitudinal grooves, capars which span and cover the joints between said glass plates and have lower edges seated in longitudinal grooves in alinement with the sup porting edges of said frame, the width of said grooves and the thickness of said lower edges being substantially the same, and securing dev1ces, substantially as set forth.

2. A skylight structure comprising a metal frame having supporting edges, glass plates supported on said edges, rocking bearings comprising split tubes mounted on the supporting edges of the frame and between the plates and said supporting edges, and

means for holding the parts in place, substantially as set forth.

3. A. skylight comprising sections connected together, each section comprising channetirons, sections of corrugated glass supported. on the upper edges of said channel-irons, cap bars covering the space between the adjacent edges of said glass sections and with one lower edge resting in a corrugation of said respective glass plates, and immediately over and in alinement with the supporting edges of said channel-iron, tubular lead rocking bearings having longitudinal openings interposed between the supporting edges of said channel-iron and the glass plates, said longitudinal 0pen ings allowing of limited rocking movement of the bearing tubes, clamping means for holding said parts in position, a support extending from beneath the upper end of one channel-iron to beneath the lower end of the adjacent channel-iron across the end of said lower channel-iron, and means for securing said support, substantially as set forth.

4. A skylight structure comprising channel-irons having upturned supporting edges, glass sections supported on the upturned edges of said channel-irons, bearings consisting of tubular members having longi tudinal openings, lead parts mounted to; rock on the upper edges of said channelirons and forming rests for said glass sections, said glass sections being formed with longitudinal grooves or corrugations in their upper surfaces, a cap bar having down-turned edges adapted to straddle the space between the edges of said glass sections and having its lower edges fitted in said corrugations or grooves immediately over and in alinement with the supporting edges of said channel-irons, and means for securing said parts together, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Philadelphia, Pennsylvania, this 5th day of April, A. D. nineteen hundred and seventeen.

Copies of this patent may be obtained for five cents each, by addressing the. Commissioner of Patents,
