To fasten the tie-beams down upon the wall-
plates I make in the former a beveled gain,f,
and upon the wall-plates I fasten a beveled
key, f'. By placing the tie-beam 'Upon the
5 wall-plate, and then slipping the former along
laterally until the key f'enters the gain f, the
beam will be held down securely. A projec-
tion of any desired length may thus be given
at the eaves, and a cornice finish produced by
ro fastening the verge-boards M iM to the pro-
jecting ends of the tie-beams.
It may be here stated that the gains a a
may be made to fit the purlin, in which ease
tho purlin should be inserted endwise into the
r5 said gains, and the keys L L will not be abso-
lutely-essential; but I deem it best to make
the said gains long enough to permit the pur-
lin to be dropped into them, and to use the
said keys for the purpose set forth.
20 Having thus described my invention, wbat
I claim as new, and desire to secure by Letters
Patent, is-
1. The combination, in a roof, of the T-
shaped caps or battens G G, having in their
25 depending tongues the transverse dovetail
grooves o' c', the roof-boards F F, arranged
above the grooves e' c' and below the horizon-
tal or lateral arms of the said battens, and
the purlins E E, adapted to enter the grooves
30 c' dc and grooved longitudinally to engage the
said tongues, substantially as and for the pur-
poses specified.
2. The combination, in a roof, of the pmulins
E E, having thereon the ribs a" a", and hav-
35 ing on one longitudinal edge thereof the V-
shaped groove a', the rafters D D, having
therein the dovetail gains a a, and the rootf-
boards, having therein the gains or grooves
b b, substantially as and for the purposes
40 specified.
3. The combination, in a roof, of the T-shaped caps or battens G G, the roof-boards
F F, the purlins E E, and the rafters D D,
when the said battens overlap and depend be-

the said battens and rafters have therein dove-
tailed grooves, and the purlius have V-shaped
grooves to admit of their being connected to
each other, substantially as and for the pur-
poses specified. 5o
4. The combination, in a roof, of the roof-
boards F F, having therein the grooves or
channels b' b', and the T-shaped caps or bat-
tens G G, covering the said grooves or chan-
nels and depending between and below the 55
said boards, and having in their lower edges
transverse grooves c' c', for adapting them to
be locked to the frame by means of corre-
spondiungly - forimed purlins, substantially as
and for the purposes specified. 60
5. The combination, in a roof, of the dish-
ing roof-boards F F, having therein thegrooves
or channels b' b', and the T-shaped and dish-
ing caps or battens G G, extending between

or channels, substantially as and for the pur-
poses specified.
6. The combination of the T-shaped caps or
battens G G, having therein the dovetail gains
d' o', the roof-boardsF F, and the purlins E E, 70
having therein the grooves a' a', substantially
as and for the purposes specified.
7. The combination, in aframe house, o the
well-plates A A, the tie-beams B B, arranged
