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

 in front of the line containing the price. 



The prices of the engines include the engine itself with foundation base, centrifugal governor, magnetic 

 apparatus, carburetter, exhaust box, starter handle, spanners, oil can, foundation bolts and spare parts. 



Re the employment of the accessories mentioned in the table, kindly note the explanatory remarks regarding 

 the high speed gas engines. A gas pressure governor is not used, but a fuel tank and 1 petrol conducting pip<' 

 (1 s. 4 d. per metre) are necessary. 



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

 the dynamos for 65 or 65/90 volts, listed on pp. 147 and 148 should be connected up with one of the preceding 

 engines by a belt drive. For direct coupled sets, see p. 137. 



High Speed Gas Engines direct coupled with Direct Current Dynamos: Dynamos for 65 volts. 



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

 in front of the line containing the price. 



**) The gas engine has magnetic ignition. With tube ignition the prices of the engines to 4 HP. are about 

 11. 5. lower. Magnetic ignition ensures regular, smooth working. 



The prices of the engines comprise: the engine with dynamo on one base plate; foundation bolts: 

 slide rails and ties for the dynamo, with elastic coupling, fly-wheel, centrifugal governor, magnetic ignition, 

 gas bag and mixing valve, exhaust box with connections, but without lead; also some accessories and spares. 

 If engines with tube ignition are desired, glow tubes with burner and chimney and some spare tubes are sup- 

 plied along with the engine. 



The following are necessary for working: a gas pressure governor, to prevent the lights connected up to 

 the gas lead being disturbed by the running of the engine; a cold water lead connected to a pressure supply (this 

 must be made on the spot and cannot be quoted for in advance); or a cooling tank, if there is no water lead 

 available or if it be desired to cut down the water bill, together with a masonry or heavy wood base (to be pro- 

 vided on the spot); in addition, a cooling pump, where this is mentioned in the above table of prices, for in- 

 creasing the circulation of the water; an exhaust lead, which should be provided on the spot; and a silencer. 

 A gas meter is also supplied at an increase of price, if desired. 



For regulating the pressure of the dynamo a shunt regulator is necessary. If it is desired to take off also 

 alternating and three-phase current, an order should be given us for 4 slip rings to be fitted. 



Regarding switchgear for the machines, we shall be happy to furnish a separate estimate, if desired. See 

 also the estimates on p. 138. 



For lighting purposes, the models to 4 HP. can only be employed when a battery is used simultaneously; 

 even in the case of the larger models it is advisable to have a battery of accumulators in parallel. Prices of 

 suitable dynamos and batteries on application. See also the estimates on p. 138. 



If desired, dynamos for 110 or 220 instead of 65 volts can be supplied, as well as dynamos for charging 

 accumulators without changing the speed.
