"Vintage Machinery" entry for Atlas Engine Works

I have devised an improved arrangement of the parts for transmitting power from the engine to the driving-wheels. I use a single engine, with the obvious economy of construction and repair and the diminished friction due to such, and have connected an efficient device f for starting the engine when it is stopped on the center.


1. In a portable and traction engine having a chain, D, for communicating power to the bearing-wheels W, the shaft I, turning on a fixed center, and the shaft H, turning on a movable center, in combination with means, C C, for adjusting the position of the latter in a path concentric to I.

2. In a portable engine having a single cylinder, the friction-piece R, rod Q, lever P, and connection N, adapted to serve as herein specified.
