Standard Single-Cylinder Horizontal Engines

10 TO 70 EFFECTIVE H.P.

These engines embody all the merits of the National engines we have sold since the firm came into existence, as it has always been our policy to keep in the very front rank with onr productions. We have sought to embody in them all the best points of other makers, together with the special features covered by our own patents. With this object in view we have made exhaustive investigations of British and Continental practice, and subsequently have re-designed all our models so as to give our clients the full benefit of the very latest improvements.

With this explanation we confidently invite a study of the engines' de6%bed. in the following pages, and we specially draw attention to the following new features of the standard designs of National gas engines from io Effective H.P. upwards :—

Girder Bed and supported Cylinder.

Ring Lubrication to Crank Shaft Bearings.

Positive Pump Lubrication to Cylinder and Crank Pin, 20 Horse-Power upwards.

Balanced Cranks on all Engines.

Improved Electric Ignition with Variable Timing Gear.
