He became anxious to open the valve, but having lost the use of his hands he could not, and ultimately he did so by seizing the cord with his teeth and dipping his head two or three times.

The roaster can be converted into an oven by closing the valves, when bread and pastry can be baked in it in a superior manner.

Q.Will you explain the operation of setting the valve of a locomotive?

The gong signaled stand by, stop; he shut the valve and presently heard the anchor plunge and the rattle of running chain.

Below each side of the octagon there is a bent flat spring, which lifts up the octagonal plate, and with it the packing ring against the back of the valve casing; and should water get into the cylinder, it escapes by lifting the valve, which is rendered possible by the compressibility of the springs.

The line M represents the connecting rod, to which motion is imparted by the beams, through the medium of the cross tail extending between the beams, and which by means of the crank turns the paddle shaft S. The eccentric which works the slide valve is placed upon the paddle shaft.

As a rule, of course, they are comic, and the agony they cause may find a safety-valve in laughter.

The dimensions of safety valves, however, in practice are very variable, being in some cases greater, and in some cases less, than what the rule gives, the consideration being apparently as often what proportions will best prevent the valve from sticking in its seat, as what proportions will enable the steam to escape freely.

In such a case is it a sound policy to try to avert the possibility of an explosion by screwing down all its safety-valves?"

A casing set beside the cylinder contains the valves, by means of which the steam which impels the piston is admitted and withdrawn, as the piston commences its motion in each direction.

Mr. Porter warrants the following action in this governor, operating any regulating valve or cut-off which is in reasonably good order.

An authority says, "Bring your engine to a dead center and then adjust your valve to the proper lead."

A.In modern engines, either marine or locomotive, it is found that if they are fitted with the link motion, as they nearly all are, a very good expansive action can be obtained by giving a suitable adjustment to it, without employing an expansion valve at all.

In arranging the independent cut-off on the Joy gear, it is only necessary to increase the length of the vibrating link beyond the point of attachment for the main valve spindle connection to obtain a point from which motion may be taken to actuate the cut-off valve; even then the cost of the Joy gear for both cylinders is but little more than for a single set of link gear.

The foot valve is situated in the bottom of the air pump, and its seat consists of a disc of brass, in which there is a rectangular flap valve, opening upwards, but rounded on one side to the circle of the pump, and so balanced as to enable the valve to open with facility.

This opening is guarded by the folds of the membrane forming the ileo-cæcal valve, which permits the passage of material from the small to the large intestine, but prevents its backward movement.

It is only your pseudo-saint, who cuddles himself for the pulpit and the platform, and keeps the safety-valve down with midnight sittings while "rosining up" the furnaces with strong coffee, that will come to grief by collapse of flues.

Mr. C. ordered the man to let down the valve, but he became confused, and instead of letting go the string which lifted the valve, he pulled on it the more.

The effect, therefore, of moving the valve up and down, as is done by the eccentric, is to establish a connection alternately between each cylinder port and the central passage whereby the steam escapes; and while the steam is escaping from beneath the piston, the position of the valve is such, that a free communication exists between the space above the piston and the steam in the boiler.

What cell of goodness is there within the human heart, of which the breath of sorrow cannot raise the valve?

I took the cap off of the horizontal check, just forward of the pump barrel, and took the valve out and discovered that the check was reversed.

When should you test or try the pop valve? A. As soon as there is a sufficient pressure.

The rough tossing about the Flying Fish had received had jammed the needle valve, but that was all.

The steam and water piston being on the same rod, but momentum is obtained to throw the valves by means of a fly wheel, placed beyond the pump, and connected with the piston rod by a cross head and a yoke.
