 ing breakdowns, and very often stripping 

 the cog-wheels of their teeth. This has all 

 been overcome in the Marbach device, 

 because the strain incident to reversing is 

 placed entirely on the brake-lever, relieving 

 all stress on the gears. Another feature of 

 this machine is that it can be reversed while 

 in motion: a pressure on the brake lever 

 slows d<jwn the reeL when, presto! the 

 combs are flopped the other side to in the 

 fraction of a second — so quickly, indeed, 

 that it seems like a sleight-of-hand perform- 

 ance.

In some localities, where a large amount 

 of extracting has to be done, the extractors 

 are driven by water-motors .gasol ine-engines. 

 or any other small power. Little gasoline- 

 motors have now arrived at such a state 

 of i>erf ection that they are exceedingly reli- 

 able and efficient, and in view of the fact 

 that a 5team-€ngine is expensive, and that 

 a water-motor is out of the question for 

 most localities, the internal-combustion 

 engine, driven by the force of an explosion, 

 is the mc^t available power for this purpose. 

 Small air-cooled engines of this type are 

 now made in one-hor^e-power sizes that win 

 drive a honey-extractor with a consumption 



of gasoline of only one quart for a run of 

 ten hours, and the cost of the engine is only 

 from S-50.00 to $75.f<j at the factor?-, and 

 they are so simple in construct^jn that any 

 child capable of reading and understanding 

 directions can manage them. 



The method of transmitting the power of 

 the engine to the machine is shown in the 

 ac-companying illustrations. In view of the

fact that it is not practicable to stop and 

 start a gaadine-engine every time the combs 

 are taken out of the extractor, and replaced, 

 a loose belt with idler is employed so that 

 the extractor can be stopped and started — 

 in fact, any speed desired obtained — simply 

 by a pressure on the lever that holds the 

 idler used to increase the tension on th*- 

 belt. This form of tran^nission of power
