This invention relates to the general class of machines known as crank shapers and using a bull gear and crank for operation. It is also capable of application to crank planers operated in the same way or any other machine of similar character. In these machines the bull gear is driven by a pinion on its periphery and delivers power from the side of the gear by means of a crank pin, the offset of which is adjustable.

The principal object of the invention is to provide an inclosure to enable the bull gear to run in the same compartment with the other driving gears, so as to arrange for the same lubrication of the bull gear as the other gears of the driving train.
