CLEANING TRUNK.
On the [opposite page] is shown a 10-ft. section of Automatic Cleaning Trunk. It is usual to install two of these sections, making 20 ft., and to suspend same from the ceiling.
The cotton passes over Transverse Grids A and the leaf and dirt drop between the Grids into a series of compartments B, which are automatically cleaned out by air draft from a Fan. Each compartment has a hinged door or bottom C, which when dropped leaves an opening into the exhaust air pipe D. The hinged doors are dropped one at a time, and the openings are shown at G.
The Fan is connected to the exhaust air pipe D, and is only running while the Trunk is being cleaned.
The removable doors E give access to the top of the Trunk, and the brackets F are for the supporting rods.
One of the advantages of this Trunk is that it can be hung from the ceiling out of the way and not occupy valuable floor space. It is carefully built and the joints of the doors are covered with leather to prevent leaks.
[Page 59] shows a system where 20 ft. of Automatic Cleaning Trunk is used together with the necessary Conducting Trunk; the Opener being on the first floor and the Breaker Lapper with Gauge Box and Condenser on the second.
ENGLISH PATTERN CLEANING TRUNK (TWO 4-FT. SECTIONS)
Cleaning Trunk is of special advantage to mills using low grade stock. All cotton contains more or less light dirt and leaf, which it is difficult to entirely remove in the Lappers, on account of the fan draft essential to the formation of a good sheet on the screens carrying some of the lighter impurities along with the cotton. The passing of the stock over the transverse Grids in the Cleaning Trunk at a low velocity provides an efficient means for removing this dirt and leaf.
We also build an English pattern Trunk, which is shown in the illustration on [page 22]. This Trunk is supported by stands which rest on the floor, and is built in 4-ft. sections, several of these being coupled together. Although not automatic, it is easily cleaned by dropping the doors which cover the entire bottom of the Trunk and carry the Grids. In the illustration one of these doors is shown down, and the sheet iron Grids are plainly visible.
