510 NEGKETTI AND ZAMBEA, HOLBORN VIADUCT, E.C., 



GAS MOTOBS. 



THE NEW PATENT 5-MAN POWER VERTICAL "OTTO" GAS ENGINE, 



VERY SUITABLE FOR DRIVING SMALL ELECTRIC INSTALLATIONS, 

 AMATEUR WORKSHOPS, PUMPING WATER, &C., &C. 



3133 Gas Consumption. This Engine (fig. 3133), has been designed to meet the 

 demand for a small Gas Engine that will consume G-as only at the same rate as 

 the " Otto ; " the smallest " Otto " Engine hitherto supplied being too large for 

 many who want power. Power. The Engine will give off one horse-power on the 

 pulley ; but, of course, the consumption of gas is in proportion to the power required ; 

 and if, say only one man-power is taken from the Engine, the Governor will cut 

 off the gas to suit. This Engine is really well made. The crank is of steel, and 

 other materials of the very best are used. All working parts are easily replaceable, 

 and are made strictly to gauge. Unlike most small Gas Engines of other makes, it 

 is fitted with a sensitive and patent Governor. It stands in a space of about 3ft. 

 square by 4ft. 8in. high. 



Lithographed Foundation Plans, giving Sizes of Pipes, Meter, &c., are supplied, 

 together with a Book of Instructions for Working." Each Engine is sent off erected 

 almost complete, only the Fly-wheel and Pulley being detached. 



Price 45, with one set of Yalves. (Water Yessel, 20s. extra.) 



3134 The 5-Man Power Vertical " Otto " Gas Engine is also constructed in com- 

 bination with a Dynamo Electric Machine, capable of working 6 to 8 

 Incandescent Lamps. The Dynamo is connected to the Engine by a 

 simple mechanical arrangement, so that when not required for lighting 

 it can be quickly thrown out of gear, and the Engine made available for 

 other purposes. Our engraving (fig. 3134), shows on an enlarged scale the 

 5-Man "Otto" Engine with the Dynamo Machine attached. 

 Price, complete with Dynamo Electric Machine, as fig. 3134 . 75
