pound levers and weights to regulate the pressure required. The two rolls are geared together by strong shrouded wheels, and driven by a strong cast-iron spur-wheel and pinion, a driving-shaft, fast and loose pulleys,, carried by cast-iron stands and pedestals fitted with brass steps. The machine is fitted with two metal feed-tables, and a self-acting apparatus for returning the sheets to the rolls, and a -handle-lever, slide-bar, and ^8- *"■

strap-forks for starting and reversing.

Plate-planing Ma c h i n e.— This machine, which is manufactured by Messrs. Bryan Donkin and Co., of Ber-mondsey, is shown in Fig. 51. By its aid the plates of

rajf-engines can be sharpened without being taken to pieces. The slide of the machine is made exactly like the roll-bar planing machine (see below), and is so arranges! that it can easily be taken off and used for sharpening roll-bars. Boll-Bar Planing Kachino. —In the accomparying

engraTing (Fig. 52) is shown an apparatus fitted to a

rag-engine for Bharpening rag-engine roU-bars, and it vill be seen that by means of it the operation can be per-

formed witW removing the roU from its usual poaition. J-be edges of the bara are firat

planed by a tool supplied by

the mauufacturers to render

the whole cylindrical before

sharpening them; the bevelled

sides are then planed by suitable toola, two of which accompany the apparatus. This

method of aharpening renders

the bara uniform in shape, the

roll is kept in better working

order, and it can be dressed

in considerably less time, and

at less expense, than can be

done by chipping by hand, Wa»liiiig^lind«rforBa? Fi„ 53

Engine—The illustration at

Fig. 53 represents the machine as manufactured by Messrs. Bryan Donkin

and Co. It is so made "^

that the water is delivered on the driving side of the rag-engine, thus avoiding any trough across the engine, and admitting o£ the midfeather being thin, as is usual in cast-iron engines. It is all self-contained, and the driving apparatus is wholly on the outside of the engine. The raising and lowering are effect^ by a worm and worm-wheel, so that the cylinder will stop at any point required.

A three-roll smoothing press, for smoothing the paper at the end of a paper-ma-chine,also by the «ame makers, is shown inFig.56. Back-water ^ttmp —Theen-graving (Fig.
