thiitmi gime @tutti @titte Letters Patent No. 99,656, dated .February 8, 1870.-
IMPROVEMENT IN" SHEET-METAL ROOFING.
The Schedule referred to in these Letters Patent and making part of the same.
same time, the fastening of" the sheets to the lining,
by means of knee-plates beneath the sheets, in such a manner as to dispense with nailing-the latter, thereby having no nail-heads exposed to the action of the? weather, as ordinarily,- which, as is well known, is a great objection, as the corrosion of `the heads when thus exposed weakens them, and frequently causes a leakage.
The use of the knee-plates at the joints of the sheets also gives greater security to the roof, to prevent the sheet-s heilig raised or torn off by high winds.
lo enable others skilled in the art to which my improvement appertains, tojmake a practical application of the same, I will now give a detailed description thereof.
ln the accompanying drawings, which make a part of this specification- Figure l is a top view orplan of the improved roof.
Figure 2 is an isometrical view of one of the metal sheets D.
Figure 3 is a like view of one of' the holding-down knee-plates E.
4Iiigure d is a longitudinal section, at the line a b of fig. 1, before the turned-up edges a a' of the sheets D are bent over.
i Figure 5 is alike view, at the line c dof iig. 1, which illustrates the double bend of the sheets.
Figure 6 is a cross-section of the root', at the line e j' offig. l. v
Like letters in all the figures indicate the same parts.
A is a portion of the roof, having lining B,-on the rafters O, to receive the sheets I), which form the covering.
These sheets are constructed with turned-up edgesa and a', at their side edges, for the construction of the vertical joints 11, and with flat bends c c', at their ends, for forming the horizontal joints d. One of the plates is represented in detail in fig.^2. I
The ends of thesheets, by which the comb of the roof' is constructed, have not the fiat bends c, but have turned-np fia-nges a and a', for forming double bends like those ofthe vertical joints b, which are seen in detail in iig. 5.
The comb-joint b is shown in det-ail in fig. 6, as
also the at lapping joints b", which connect the ends of the sheet D.
The first'be-ud above mentioned is merely the bending of the edge of' the flange a over the edge of the fiange a', the former being made higher than the latter for that purpose.
In the second bend, both flanges are bent together, and the prongs e and e' of' the knees E in connection therewith.
I'lhe contiguous edges of` the sheets D are confined to the lining B, by means of the holding-down kneeplates E, shown in detail in fig. 3. These pieces are formed of strips of metal bifurcated at one end, to form the prongs e and c. i
In laying the sheets D, I first confine a bent-down edge or flange of the. first to the end ratter, by means of nails which are placed in appropriate holes in the flanges of said sheet-s, in the usual manner. Then, at suit-able distances apart, I place holding-down kneeplates E, against the npturned flanges a of the plates or sheets D, and bend the prongs e over the saine, and nail the bottom part of' knee to the lining-B. Then, a course, fr, is laid with the turned-up edge a against the upright portion, f, of the knee-plates E, and the prongs e' bent over the said edge a to confine the' sameto the edge a., and to hold the contiguous edges ofthe sheets D iirlnly to the lining B. The arrangement of the several parts is shown iu detail in tig. 4.
The end joints (l of the sheets are formed by flat interlocks, as seen in fig. (i.
After the flanges a and a are connected, by means of the knee-plates E, as above described, a double' bend is given them to make perfectly water-tight joints, as represented in fig. 5;
'lhe laying of the sheets forming the remaining courses ofthe first side ofthe roof' is continued in the same manner, to connect their vertical edges, and confine them to the lining B. Then, the other side of.
the roof is laid in the saine manner.
The comb-j oint if of' the roof' is made, andthe sheets confined tothe lining B, beneath-itrin the saine manner as the Vertical joints b, the formation of the joint being carried along as each succeeding course of' the sheets D is laid.
'When the sheets are laid on both sides of' the roof, as above described, the vertical joints a are hammered down at their connection with the comb b', and at the eaves of the roof, to make a iinish, as seen in fig.'6, and also to tighten the joints at those places.
What I claim as new, and desire. to secure by L'etters Patent, is-
The combination and arrangements of the holdingdown knee-plates E, having two flanges e e' with the lining B and sheets D, substantially in the manner and for the purpose above set forth.
In testimony that the above is my invention, I have hereunto set my hand and affixed my seal, this 24th day of August, 1869. p
