187. Thirlmere Motor.
188. Hydraulic Blower.
Hydraulic Engines are made in various forms, being commonly worked in a similar manner to a steam engine, water under pressure acting upon the piston in place of steam. Fig. 186 represents a “Haag’s” patent water motor adapted for a chaff-cutting machine; Fig. 187 a series of “Thirlmere” water motors, showing the capacities; Fig. 188 a Bailey’s patent hydraulic blower, for chamber or church organs, smiths’ bellows, &c. All these motors are manufactured by W. H. Bailey & Co., of Albion Works, Salford, Manchester, and being small and inexpensive, they are very suitable and convenient for working sewing machines, knife cleaners, washers and manglers, and any domestic machine that entails considerable labour. The power of these motors varies with the pressure of water, if connected with the town’s main (by arrangement with the water company), a very high pressure is generally obtained.
A “Haag’s” motor, No. 2 (smallest size), gives from ¼ to ½ horse-power, 220 revolutions (of the flywheel) a minute, and costs 10l. A “Thirlmere” motor, No. 00 (smallest size) gives from 1/70th to 1/30th of a horse-power, and costs 2l. 2s. A Bailey’s blower No. 1 (smallest size), at 50 lb. pressure, gives a boy power with a 10 in. stroke, and costs 6l. 6s., and is suitable for a chamber organ; these latter are made to work either vertically or horizontally.
189. Ramsbottom Engine.
Fig. 189 is a “Ramsbottom” 3 cylinder hydraulic engine (Jno. Ramsbottom, Saynor Road, Hunslet, Leeds). This is considered one of the most efficient hydraulic motors yet made, and it possesses an advantage in having no dead points (see Flywheel of Steam Engine), and its action is exceedingly steady and uniform. The illustration will acquaint the reader with its constructive details, which are simple and few in number.
No correct idea can be given as to the cost of working these motors, for as before explained, it depends entirely upon the pressure of water obtainable.
