Section 45.—JETS, NOZZLES AND INJECTORS.

(See also [p. 102].)

[2212]. Körting’s water jet condenser; requires 3 feet head of condensing water.

[2213]. Spray jet for petroleum, water, &c., with air blast.

Automatic spray jets or sprinklers are constructed to spread or spray water over a considerable area by the force of the issuing current, for extinguishing fires, watering gardens, &c.

Fountain jets are of many forms to deliver the water in close, spreading, or fan-shaped forms, artistically arranged.

[2214]. Spray jet, with spiral core.

[2215]. Spray jet, with annular orifice and dish-plate.

Section 46.—JOURNALS, BEARINGS, PIVOTS, &c.

(See also [p. 102].)

[2216]. Pedestal bearing, with four brasses and set screw adjustments.

[2217]. Hydraulic oil pivot for vertical spindle. Oil under pressure is forced into the channels between the bearing faces, the area and pressure being adjusted to the load. The surplus oil is returned from the oil well to the pump.

[2218]. Adjustable intermediate bearing for a vertical shaft. It has three brasses set up by set screws and wedges.

[Larger plate.]

[2219]. Long bearing, with oil circulation.

[2220]. V bearing, or support for a shaft or telescope.

[2221]. Plain double bearing, with one cap and one bolt.

[2222]. Vertical shaft bearing, formed of two similar toe-pieces of very hard steel running in oil.

[2223]. Pedestal, with side adjusting brasses, set up by set screws.

[2224]. Vertical shaft bearing, similar to [No. 2222], but with small coned toe-piece of very hard steel.

[2225]. Thrust-bearing for collar screw, having a loose collar secured by two pins, drilled half in the collar and half in the base.

[2226]. Similar bearing, with a loose collar screwed in and locked by a set pin.

[2227]. Similar bearing; the screw has a thick collar, with a turned groove and a pin drilled half into the collar and half into the base.

[2228]. Vertical pivot, with hardened screws.

Ball bearings. See [Section 70].

Roller bearings. See [Section 70].

[2229]. Bearing, with side brasses, set up by a set screw.

[2230]. Bearing, with 3 brasses, set up by a set screw.

[2231]. Bearing, with 3 brasses, the side brasses set up by wedge bolts, regulated on top.

[2232]. Bearing, with 3 brasses, set up by side wedges and top screws.

[2233]. Schiele’s vertical shaft bearing.

White metal is much used for bearings, and may be run in around a shaft. The brasses are sometimes made of skeleton form to receive white metal in this way.
