gasoline engines does not differ greatly from that of the engines working with illuminating gas. Exact data are 

 given for each individual case on application. t 



For prices for direct coupled high speed gas-dynamos see p. 136. 



The low speed engines listed on the previous page are characterised by particularly smooth running and 

 the greatest certainty in their action. t- 



Low Speed Internal Combustion Engines for liquid Fuels (of. Figs. 50,571 and 50,575), horizontal type. 



These en.srines can be fitted to work with petrol, heavy 

 benzine, benzol, crude benzol, petroleum, spirit or ergin. 



*) When ordering, in addition to quoting the list number, please mention the letters a, b, c, etc. placed 

 in front of the price line, and also the kind of fuel to be used. ^ , 



50.580. Fuel Tank for 200 litres fuel ................................ 1. 5. 



50.581. do., for 300 litres .................................... 1. 15. 



The following are included in the prices: the engine with heavy fly-wheel, suitable for electric light work, 

 with lengthened shaft and external bearings, base plate and foundation parts to the external bearings for masonry 

 foundation; benzoline tank, exhaust box, tools. The foundation parts for the engine itself should be ordered 

 separately. The engines are supplied with magneto ignition and guided valve gear. 



Packing and erection are charged separately. 



The combustion engines are arranged for pressure-flow cooling, and the water necessary for this purpose 

 can be taken from the water supply. If, however, water is not laid on, a cooling tank corresponding to the size 

 of the engine should be ordered at the same time. 



For prices for direct coupled high speed internal combustion engines with dynamos, see p. 137. 



The preceding low speed engines are characterised by specially smooth running and greatest safety in 

 working: the horizontal type securing easy access of the working parts and simplifying the work ( f the attendant. 



High Speed Gas Engines. 



*) When ordering, in addition to quoting the list number please mention the letters a, b, c, etc. in front 

 of the line giving the price. 



The above motors have magneto ignition. The smaller models up to 3 HP. are also supplied with tube 

 ignition, entailing an increase in price of about 11.5.0. Magneto ignition secures a regular, smooth action. 



The prices of the gas engines include the engine with foundation bearing, centrifugal governor, gas mixing 

 valve, rubber bag, exhaust box. starting handle, foundation bolts, and a few accessories and spare parts. If 

 engines fitted with tube ignition are desired, tubes with burners and chimney and a few spare tubes are sent with 

 the engine. 



The following are requisite for working the engines: a gas pressure regulator so as to obviate disturbing 

 the lighting connected with the gas lead because of the engine; a cold water main connected to a pressure water 

 lead (this must be made on the spot and cannot be quoted for beforehand); or a cooling tank, if the water is 

 not laid on or if the water bill has to be kept low: together with a masonry or heavy wood base (which should 

 be obtained on the spot), also a cooling pump where this is shown in the above table of prices, for increasing 

 the circulation of the water: and an exhaust lead, to be provided on the spot. A silencer should also be provided. 



For generating direct current for the projection lantern and other lighting or experimental purposes, one 

 of the dynamos for 65 or 65 00 volts, listed on pp. 147 and 148 should be connected up with one of the gas 

 engines by a belt drive. For prices for direct coupled gas dynamos, see p. 136.
