_Facing-plate._--This useful tool was invented by T. C. White. It
consists of a brass plate large enough to fit readily into the bottom of
the raisin box. In this plate are arranged small cavities, each one wide
enough to hold a large raisin. For large boxes the plate is made to
contain eleven raisins the short way and eighteen the long way. The
plate is first placed in the bottom of the iron frame in place of the
loose bottom. A raisin is placed in each cavity and lightly pressed, and
loose raisins are carefully filled in on the top. When this frame is
afterwards reversed and the raisins and the plate as follower are
received in the box, it will be found that the top layer has retained
its arrangement and is regularly faced. This facing-plate enables the
packer to face quickly and cheaply, but it can only be used when the
top-down method of packing is used. The standard plate is nine inches by
eighteen inches, and the plate for cartoons is five inches by ten
inches, both made of heavy brass.
_Scales._--For weighing the quantity of raisins necessary for every
layer, scales must be found on every weighing table. Any ordinary
grocery scales which work with springs may be used. Generally one pair
of such scales are used at each end of the assorting table.
_Labeling Press._--Of late every large packer labels his boxes before
they are nailed together. This is done by passing the shooks through a
labeling press, which prints under pressure the required label on each
side or top, the name, etc., appearing in concave type on their face.
These presses are run by machinery and work very rapidly.
_Tables._--In the packing-house are tables of various kinds; they are
generally long and narrow, and about four feet wide. The assorting
tables should be furnished with square holes at intervals of five or six
feet, so that the loose raisins may be scraped through them into boxes
below. The assorting and weighing tables are furnished with a low flange
or guard all around, to prevent any raisins falling on the floor.
_Bags and Bag-holders._--Two kinds of bags are used,--cotton sacks or
jute sacks. The former are white like flower sacks, the latter coarser
and brownish. In the former no paper linings are used, but in the latter
a paper bag is stitched, in order that the air may not penetrate and dry
the raisins. Both kinds of bags are used to an equal extent. The cotton
sacks contain either thirty or sixty pounds, while the jute sacks are
made to contain an average of eighty pounds each. Patented bag-holders
are used everywhere for holding the bags open while they are being
filled.
_Trucks._--For inside work, trucks very similar to those used in the
vineyard are now generally adopted. They are handled with ease, and for
moving boxes of various kinds are absolutely indispensable in the modern
raisin packing-house.
