When the bolt is closed, or only partly open, the cut-off may be turned up or down as desired, but if the bolt is drawn fully to the rear, the magazine can not be cut off unless the top cartridge or the follower be pressed down slightly and the bolt be pushed forward so that the cut-off may be turned "off.

The cut-off is kept turned "off" except when cartridges are actually used.

It is unnecessary to insist on the great economy attained by using steam with a well-regulated cut-off, for practical men know now that the essential points of excellence in the steam engine are a good boiler, which generates the greatest quantity of steam for the least consumption of fuel; and, secondly, a reliable cut-off, which uses the steam to the best advantage, by admitting the proper quantity for the work required.

A distance above, they went through a cut-off, and saved a mile or more, while we went round, showing their superior knowledge of the geography.

Most of them were listed for Oregon, and were resting their cattle preparatory to entering upon the long, dry drive of forty miles, known as "Greenwood's Cut-off.

The dangers and difficulties encountered by reason of taking the Hastings Cut-off had all been surmountedtwo weeks more and we should have reached our destination in safety.

Usually, the threads, both right handed and left handed, are cut upon the cut-off valve stem itself, which must be so connected with the eccentric rod as to admit of being turned; and in most cases the valve stem extends through both ends of the steam chest, so that it must both slide endwise and turn upon its axis in two stuffing boxes, necessarily of comparatively large size.

Consequently, we may let R C S, parallel to L O M, represent the face of the cut-off valve seat, or, in other words, the back of the main valve, in which the port, C N, corresponds to one of those shown in Fig.

But again, in order that the cut-off may operate in the same manner when backing as when going ahead, this eccentric must be symmetrically situated with respect to both C and G; and since L O M bisects and is perpendicular to G C, it follows that if the cut-off eccentric be fixed on the shaft, its center must be located at H, the intersection of C T with L M.

This would require the edge of the cut-off valve at the given instant to be at Q, perpendicularly over H; and the travel over the main valve would be equal to twice C H, the virtual lever arm of the eccentric, the actual traverse in the valve chest being twice O H, the real eccentricity.

The edge of the cut-off valve will then be at N; it instantly begins to close the port.

But though he was thus cut-off in early manhood his name will live for ever.

The boiler pressure is 150 lb., and the usual point of cut-off in the high pressure cylinders, when running at speed, is half-stroke, while the pressure of steam admitted to the large cylinder is never to exceed 75 lb. per square inch.

By the use of the Joy gear, cut-off valves may be fitted to both cylinders, that for the low pressure being fixed at the constant position required by the proportion of the cylinders, while that on the high is adjustable; of course, in this case, the position of the quadrants must be only changed for reversing.

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.

During the early part of the stroke, the energy of the steam piston must be stored up in the moving parts, to be given out when the steam pressure has been reduced through an early cut-off.

On one of these, about six miles from Harmony, called the "Cut-off," we determined on encamping.

The valves are cylindrical, and are driven by independent eccentrics, the spindle of the cut-off valve passing through the center of the main valve.

Several years ago a "cut-off" was made across this peninsula, for the purpose of shortening the course of the river.

This map was quite frequently exhibited and the matter freely discussed in camp, indeed speeches were made in the interest of the cut-off route which was to be so much shorter.

He also stated that it could probably be as easily traveled as the one by way of Los Angeles, and as a consequence of his talk, cut-off fever began to rage in camp again.

Now we rescue it from these cut-off ones!

I asked the driver his reason for this, and he explained that it was a cut-off, and that by taking it we would save three miles and half an hour's time.
