EDWARD WILLOUGHBY ANDERSON, of Washington, in the District of Columbia,
in the United States of North America. "IMPROVEMENTS IN DEVICES FOR
CONVERTING RECIPROCATING INTO ROTARY MOTION." A communication by
James Sanford Lamar, of Augusta, in the County of Richmond and State of
Georgia, United States of North America.
My Invention relates to mechanism for converting reciprocating into rotary
motion, to be applied to any machine or apparatus when such conversion is
desirable, and consists essentially in the combination with pulleys on a driving
shaft of a fast collar on said shaft carrying two sets of friction clutches, as herein-
after described and shown in the accompanying Drawings, in which,―
A represents the frame work or supports for the mechanism B, the piston, and
its elongated yoke, the latter being connected to the pulleys D, D, by means of belts,
bands, or ropes of wire, as shown.
The pulleys D are loosely mounted on the shaft a, and have broad rims 6 which
project on their adjacent sides, these projecting portions c being turned smooth on
their inner faces. Between the pulleys on shaft a and rigidly mounted thereon
is a collar E, which is provided on each side with a set of pivoted friction
clutches d, d³, d², which extend outwardly to the smooth inner faces 6 of said pulleys.
These arms or clutches d, d', d, are slightly inclined from the radial lines of the
wheel and have their lower ends forward of their outer ends, the latter being
pressed against the smooth inner faces of the projecting pulley rim by springs 8,
which are also attached to the collar E in rear of said clutches.

As the clutches make with the rims of the pulleys each a small angle, it is evident
that they will freely yield to said pulleys when the direction of their motion is
such as tends to enlarge this angle of contact, and will firmly engage with said
pulleys when these move in the opposite direction.
In this manner it is designed to obtain a prompt and instantaneous engagement
between the alternating pulleys and the clutches and secure a smooth and steady
motion, and to avoid unecessary noise in the operation of the engaging parts.
Having now described my Invention, and the manner in which the same may
be carried into effect, I do not wish to limit myself to the exact construction and
arrangement of devices as shown and described, as these may be varied without
departing from the peculiar nature of the Invention, but what I do claim is,-
The method and means, substantially as shown and described, for converting
reciprocating motion into rotary motion, for the purpose specified.
In witness whereof, I, the said Edward Willoughby Anderson, have hereunto
set my hand and seal, this Fourteenth day of August, in the year of our
Lord One thousand eight hundred and eighty.
EDWARD WILLOUGHBY ANDERSON. (L.S.)
