LlNING FOR (3QRRUGATED-SHEET- -METAL ROOFS.

SPECIFICATION forming part Letters Patent No. 396,824, dated January 29, 1889.

Application filed November 10, 1888. Serial No. 290,474. (No model.)

To all whom it may concern/.-

Be it known that I, WILHELM Lonnnz, siding at (larlsruhe, Grand Duchy of Baden, in the Empire of Germany, have invented a certain new and Improved Lining for orrugated-5heet-llletal Roofs, of which the following is a specification.

I have devised a construction of lining which is self-supporting and non-eonducting, and may be economically applied. The invention. contributes to the appearautm and strength of the roof, and avoids all the (lifticulties due to the loss of heat through the roof and condensation of moisture by the low temperature of the metal in cold weather.

The accompanying drawings form part of this specification, and represent what I consider the bestmeans of carrying out the in- Vention.

Figure l is an end View showing an entire roof with its lining. Fig. 2 is a longitudinal vertical section through a portn'm. The remaining figures show details on a largm' scale. Fig. 3 is an elevation, and Fig. -l a cross-section.

Similar letters of referenm} indicate like parts in all the figures where they occur.

In the ruululations of the roof (1. the bearers Z) are adjusted in certain distances-about four feet apart. These bearers consist of single ;)ieees l) b butt-jointed. A baud-iron, e, projecting to the right and the left, is nailed below. On each side I nail or otherwise socure splice-pieces e 0, so that a coherent arch is formed, which, without any fastening or connection to the corrugated sheet metal or its strutting, freely bears against the timbers of the roof, being strong enough in itself to bear the lining and also contribute to the general strength of the roof.

This lining consists of boards d, forming a close and continuous layer. Their ends are closed or lined.

or this lining will not be required; but screws or other fastenings may be applied at Various points. For better appearance, the lower Visible surface is to be painted or otherwise provided with a light-colored fire-proof coating. The entire wood may, before or after the parts are shaped, be made fire-proof by saturation with a suitable liquid. The spaces between the corrugated sheets and the lining may, accordin to requirement, be filled up with badcon du ctin g material-as, for instance, with slag, wool, or any other suitable material.

This lining offers the advantage that it may be made cntirel y of waste wood, and that it does not require any other fastening than the said nailing. It presents a lining for protection against the collection and dropping of moisture due to condensation. The lining supports itself freely, and may be quite independent of the sheet-metal roof.

Modifications may be made by any good mechanic without departing from the principle or sacrificin the advantages of the invention. I can dispense with the splice-pieces 0, using other meansas a strip of angle-iron to stiffen the ribs formed by the bearers b and keep the lining-boards d reliably in place. I can use screws instead of nails at some or all the points. I have shown tie-rods and sup porting-rods therefor, but these may be Varied or omitted.

I claim as my invention- A lining for corrugated-sheet-inetal roofs, consisting of bearers I), applied in the undulations, with splice-pieces c c, band-iron e, and the lining-boards (I, inserted in the grooves between 0 and c, as herein specified.

In testimony whereof I have hereunto set my hand, at Carlsruhe, this 19th day of Septen1ber,1888,in the presence of two subscribing witnesses.
