REFERENCE TO THE DRAWING.
Figure 1, a bell and carriage without any spring. A, pivot drove into the
wall, which the carriage moves upon; B, carriage, nine inches long; C, a
balance to answer the purpose of a spring; this may be any shape, and screwed
to the neck of the carriage; these may be of different weights, one for one
room, and a heavier for two rooms, and so on, the bellbanger changing the
balances till they do the business to a nicety; D, a screwed eye, four inches
long, to fix the wire to, and to screw out or in till the wire be perfectly straight
with the hole or crank it is next in contact with, or screwed out altogether
and the wire fixed in the hole.
Fig. 2d, a bell and carriage, the same as Fig. 1st, with this difference,
that A is made to move up or down, so as to make the wire streight, as in
Fig. 1st.
Fig. 3d, a crank on a screwed plate. A, the crank; B, the screwed plate;
C, a stop from the crank to the plate, which checks the crank to its proper
position and prevents it from being pulled too far; D, a screw, on which
may be fixed an ornamental piece of brass to hide the crank, if required; E, a
balance screwed into the crank to answer instead of a check spring; these
being of different weights you can choose one as near the weight of the handle
or pull fixed to the crank; so as just to check it, so that every pull crank
supports itself, and the bell has only to take back the wire and. corner cranks
that may intervene between the pull crank and bell.
Fig. 4, a crank, the same as Fig. 3, only it is drove into the wall by a pick.
A, a pick.
Fig. 5, a mortice crank that goes into the wall. A, a balance, the same as
Fig. 3 or 4.
Fig. 6th, a lever that screws upon the wall and pulls down by the handle A.
A, handle that is balanced to stand always thus.
Fig. 7th, a lever for fixing on the surbase, and to pull from below and
balance itself the same as Fig. 6th.

page_text: Fig. 8th, a crank with one arm, and slip pull that gives the slip before the
arm is pulled full to the check, the bell going back with a sudden jerk makes
it give a full and uniform ring at all times, so that a child pulling down to the
cheek must ring it as well as the bellhanger. A, the crank arm; B, slip pull
with a jointed head C; C, jointed head, that after pulling gives way to the
crank arms, and falls to it's present position by means of a balance. D, a balance
which must be heavy enough to take back all the wire and cranks connected
with this bell, the bell only needing a balance heavy enough to make a full ring;
E, wire to next crank; F, wire to the bell, and about eighteen inches long.
Fig. 9, a bell and carriage to strike but once. A, a pick rivetted into the
carriage, and drove into the wall; B, carriage six inches long; C, crank arm
turning on a pin with a screwed nut, so that you may turn it to either side the
carriage; D, hammer to strike the bell with, screwed or rivetted into the
crank arm; E, a pin to check the hammer from lying upon the bell; G, bell,
the same as a clock bell.
Fig. 10, a crank with one arm and slip pull, the same as Fig. 8.
Fig. 11, a roller blind to work by a ballance. A, curtain or blind rolled
round a white iron barrell; B, a brass or white iron pullie; C, a piece of tape,
painted to keep it straight when rolling round the pulley; D, a piece of brass
or iron rod, with a swivel fixed to the tape to answer as a balance to the
weight of the cloth, to make it stand at any heighth wanted. This may come
down by the batten, or carried behind the window shutter, so as not to be
seen when the window shutter is put back, taking care to put it up or down
by the rod without touching the tape. A balance may, in the same manner
be applied to Venetian blinds, window curtains, map rollers, &c. &c. &c.
