I presume one of Dawson's men was working, unknown to his fellows, with the care and maintenance party, and another, equally unknown, with the engineers who were busy upon the gearing of the turbines.

Q.Will you explain in detail the construction of the valve gearing, or such parts of it as are peculiar to the oscillating engine?

Q.Will you describe the arrangement of the valve gearing?

The pulley is from 3 to 10 inches in diameter, and makes in the larger sizes about 125 revolutions, and in the smaller 230 revolutions per minute; the higher speed of the governor being got up by gearing.

the hub D' having a socket (c) into which the spindle (s) of the governor is screwed; the end (d) of the hub D forming a journal or bearing, with a bevel wheel on its extremity to convey motion from the crank-shaft gearing to the governor and cut-off.

Motion is communicated by gearing from the crank-shaft to the bevel wheel on the piece (d) on the end of the hub D, and is communicated to the spindle of the governor, which is screwed into the socket on D'.

The machine consists of a strong truck, A, A, mounted on railway wheels, on which is placed the boiler C, the crane E, and the requisite gearing.

The same course must be pursued if any of the valve gearing becomes deranged, and the defects cannot be rectified upon the spot.

Gearing for screw engines.

We have very frequently had this question put to us: "Ought I to grease my gearing?"

This in being applied to the gear retains the small particles of mica, which soon imbed themselves in every little abrasion or rough place in the gearing, and the surface quickly becomes hard and smooth throughout the entire face of the engaging gear, and your gear will run quiet, and if your gearing is not out of line will stop cutting if applied in time.

Its name is against it and if the makers would take a tumble to themselves and call it "Mica Oil" or some catchy name and get it introduced among the users of tight gearing, they would sell just as much axle grease and all the grease for gearings.

It rose at the upward pressure of Ranger's powerful arms and legs, shoulders and back; it crashed over on its side; he stood up and, without pause or outward sign of his exertion of enormous strength, set about adjusting the gearing to action, with the broken machinery cut out.

The main engine is 10 × 24, operating, by bevel gearing and a 3½ in.

A worm gearing, actuated by a wheel on the upper side of the scaffold, causes the scaffold to ascend or descend.

Hence, by causing the foot of one or the other to travel upward, by means of the worm gearing, the upper end of the jib is either elevated or depressed.

The power is obtained by means of a pair of pumps run through spur-gearing by the belt pulleys shown.

It will be seen that by this system two of the sides of the parallelogram are capable of elongating or contracting through the unwinding and winding of the silken thread on the drums of the two cog wheels, which latter, gearing with each other, allow of the escape of but the same length of the two threads.

As each wheel passes off the rock plate, the reaction of the spring throws it up again to its former position, giving additional speed to the gearing within, which is set in motion at the passage of the first wheel, and operates the electric "generator."

I've seen it weld new teeth and build up old worn teeth on gearing, as good as new.

I noted down the following list, when he was showing us his tool-house: l. $ l. $ 6 Ploughs at 4 each = 20 24 = 120 6 Horse-carts, at 14 each = 70 84 = 420 1 Large Iron Roller and Gearing, 13

Before reaching Buffalo we found the gearing too high for some grades and for deep sand.

Twice we were obliged to get out and let the machine mount the grades, which it did; but it was apparent that for the hills and mountains of New York the gearing was too high.

On hard roads in a level country high gearing is all well enough, and a high average speed can be maintained, but where the roads are soft or the country rolling, a high gear may mean a very material disadvantage in the long run.
