A combination of machinery, by which flour, &e., isPassed through the various processes of manufacture toW'e complete preparation of the biscuit. The flour, &c., isPut into the first machine, where it is thoroughly mixed; itthen passes to the breaking-machine, where it is kneadedUutil it becomes sufficiently tenacious to be passed throughtollers. Prom these rollers it is conveyed to the adjustingfoils, which reduce it to the required dimensions. It thenPasses in a continuous sheet, by means of an endless canvas,to another machine, where it is cut, docked, crimped, andstamped. The biscuits are then divided from the wasteuough, and conveyed to the oven. The waste dough isoollected and passed by means of a shute to be re-rolled.

A curvilinear sawing-machine, or ship’s timber and
ordinary sawing frame, for sawing one or any number ofcurves in timber, with bevels of various degrees. Themachine requires only one attendant, and obtains a speedof 120 revolutions per minute.
A circular sawing or rack bench. The machine con-sists of a number of circular saws (in segments) upon oneshaft, so that by one direct feed the saws cut a piece oftimber or deal into any desired number of parallel planksor boards._

Hydraulic seed-presses. The figure in the next pagerepresents the ground plan and elevation of these presses,drawn to scale. The press No. 1 contains ten cakes of3 lbs. each; No. 2 contains four cakes of 8 lbs. each.
A pair of presses, when fixed with the pumps attachedthereto, occupy a space of 9 feet by 3 feet. They areusually placed on a stone landing of this size, to whichthe pump-cistern is securely bolted, as shown on thedrawing; and this is all the fixing required.
The presses are so portable in their construction, thatthey can be fixed up or removed in two or three days byany competent mechanic.
The pumps and valves are made of the best gun-metaland workmanship.
A pair of presses with the pumps will weigh altogetherfrom nine to ten tons.
The pumps are driven from the lever end by a con-necting rod, at a speed of about thirty-six strokes perminute, and do not require more than one-horse power towork them.
With a pair of presses, No. 2, one man and a boy work-ing the usual hours of a “single spell” (say from 6 a.m.to 6 p.M.) will make from 28 to 35 cwt. of linseed cake.
The whole of the oil is extracted from linseed by oneoperation of pressing. But in the manufacture of rape-seed it is in most cases necessary, in order to obtain allthe oil, that the cake should be worked over a secondtime: it is, therefore, desirable, when working on a largescale, to have a press expressly adapted for the first opera-tion, which is called clodding.
The current expense for wear and tear on these pressesis small, and chiefly confined to the occasional renewal ofthe leathers or packings of the pumps and cylinders.
