Plunger of feed pump.

In London alone hundreds of fortunes have been made by daring plungers in a crude article which only a few years ago was regarded as being absolutely outside the pale of the gambling marketplace.

Now, the engine starts on the outward stroke and draws the-plunger out of the chamber.

When well rolled, it is made to assume varying shapes by being forced by a powerful plunger through the perforated head of strong steel or iron cylinders arranged above a fire, so that the dough is partially baked as it issues from the holes.

And that is why I prefer him to the grenadiers and plungers with silky mustaches, and half an eye on me and an eye and a half on my money.

It will be observed that a solid steel piston, E, in the cylinder, A, is provided with a plunger on its under side, which comes in contact with an elastic packing, D; the plunger may stand as 1 to A 1,000, or as 1 to A 100, in point of area of exposed surface, as compared with the large piston head, as desired.

The clay enters these moulds, and there is an arrangement of plungers by which it is first compressed within the mould and then forced out on to an endless band or some other contrivance that receives it.
