[Illustration: COMPOUND HYDRAULIC PRESS. FIGS. 3 and 4.]

This press is shown in Figs. 3 and 4. The small rams are arranged at
either side of the large ones, which, in this case, are not inverted.
To each of the smaller presses there is a pair of boxes mounted on a
vertical column, around which they can revolve to bring either box
over the rain head. When the left hand rams rise, the material is
delivered into the cell, D, which previously has had its doors (Fig.
4) closed. To permit of the cell, D, being moved out of the way, it is
mounted so that it can revolve on one of the columns of the main
press, first into the position shown at B (Fig. 4), and afterward to C
(Fig. 3). While at D, the bale in the cell (called from its
construction a revolver) is partly lashed, the ties or ropes being put
into position. It is then rotated until it comes over the large rams,
where the bale is still more compressed and secured.

It must be admitted that this press provides for the greatest possible
economy of time, and for the largest output, for the capital employed,
which can be attained. The rams and the men are constantly in action,
and not a single moment is lost. For filling each box 78 seconds are
allowed, and there is ample time for the preliminary lashing.

[Illustration: COMPOUND HYDRAULIC PRESS. FIGS. 5 and 6.]

Figs. 5 and 6 show a modification of this press, designed to turn out
sixty bales per hour. It has only one set of long-stroke rams, with
three revolvers. The bale receives its preliminary lashing while in
the position, B (Fig. 6). Fifty-three seconds are available for
