,partment is heaLed artihciaily 70 tem'
,erature varying from 70 to 80 degrees, and C
iries the woodwork after it has been put s.
together. Window-frames, shutters, and n
other stock articles are multiplied and dealt n
with in the same manner.
Let US now watch the operations in the L
ioiners' room, and see the system by which s
this wholesale work is carried on. At the i
end Of the shop we observe draughtsman. g
With rule, pencil, ccmpasses, he is making,
on long strip of board prepared for the
purpose-the working-drawings OF win
dow.frame, from design previously furnish
ed him. Upon the margin the Dimensions
or each component piece is marked. where
it does not actually appear Of the inHpded |
size on the drawing; also any u ~
structions. Here is aspeoinelt copied
the rod las such working plan d cslled3 L
Of a door-franae--sGrosveno Crescent: Ii
height Of doors for basement. To DO kept
in dryingroom at least week.
In the 'cutting-out rooms--apartments
containing lashes, saving, planning, and
.morticing machines, driven by steam-the
stuff Ohe carpenters expression for his
raw materially is fashioned into the shapes
and dimensions indicated on the rod or pat
tern. The machine saws cut so evenly,
| that the plane has only to go over the work
after it very lightly; indeed fioor-boards are
laid down Just as they come from the saw
la few shavings being smoothed away here
and there at the seams after the floor has
been laid. Such is the mathematical &C
curacy attained by the use OF machinery,
that in making up hundred door-frames
Tor windows from the same rod, any one
tof tho hundred tenants OF the hundred Cross
pieces will exactly fit the mortioes in any
one of the same number Of uprights.*
The proper pieces are therefore taken al
random from each heap, tied up, and sent
to the joiners TO be fitted and glued together.
This is done in the quietest manner pos
sible, and il is some time before the visitor
discovers how il is that this joiners' shop
differs 80 much from those Of the old school;
there is no knocking, mo noise. The arti'
! san, instead of hammering the door after 1t
/ IS fitted and glued, places it upon screw
bench. By few turns Of the worm, the
4 sides of frame contract and force them
selves against the outer edges Of the door,
\ with the even, steallhy, inevitable pressure
: Of the Iron Stroud. The compact and pom
!. Iderous wooden leaf is then taken from the
3 press and handed off to the hotair depart
n ment, Just as printer sends away his sheets
/. from the press--in numbers hardly greater
s to the drying. room.
