BEATERS 83

the whole of the circulating or propelling of the stuff, and therefore the roll
may contain many more bars, and these may be closely and evenly spaced.
It will be evident that this process
ensures quick and uniform beating
of the stock and saves a large
amount of time. The roll is also
much smaller and lighter than is
necessary with the hollander.

This type of beater is not suit-
able for the treatment of long-fibred
stock, such as rags, as the circulator
will not deal with such material,
and in any case the treatment of
rags with such an arrangement of
beater roll would not be satis-
factory.

The Taylor beater does not
necessarily depend on gravity for
discharging the stuff to the chests,
as, by the arrangement of cocks and
emptying pipe, the stuff can be
pumped by the circulator to the
machine chests, so that the beater
may be on the same floor level as
the machine, if necessary.

Very little floor space is required
for this beater, and, being enclosed,
the stuff is not exposed to dust and
dirt from the beater room. The
roll and plate are fixed to the floor
of the beater room, independently
of the pan, in a square casing.

Another beater of a slightly
modified design, but working on
the same principle, is the Tower
beater (Fig. 24), made by Masson, [M<u^swtt<*dCo.L&

Scott and Co. Ltd. It differs from ^ ^.-ELEVATION AND PLAN OF TUB TOWER

the Taylor beater in that it occupies

less floor space in the beater room, and, being supported usually from the

ground floor, the beater room floor can be of much fighter construction.
