Description:

Abstract:

It is the object of this invention to provide a transmission and reversing gearing particularly for use in traction engines, which is at once simple and inexpensive, which is safeguarded against improper operation, and which is always capable of proper operation. To this end I have provided a driving gear and a driven gear, one of which is movable axially into and out of mesh with the other, and a third gear which may be moved transversely of its axis into mesh with the first two gears only when the latter are not in mesh with each other, the third gear being mounted so that it begins to mesh with the driving gear before it begins to mesh with the driven gear, but gets into full meshing engagement with said two gears at substantially the same time.

Claim:

A transmission and reversing gearing comprising the combination of a driving gear and a driven gear one of which is movable transversely of its axis into and out of mesh with the first two gears, and means movable with the axially movable gear for preventing the third gear from being moved into mesh with said first two gears when the latter are in engagement with each other.
