arms with which it is connected which are secured to, or formed on the plate or
frame near the bottom thereof, and the ends of the chain or cord connected with
the other drum extend from the top thereof to the arms with which they are
connected, which are secured to or formed on the plate or frame at or near the
top thereof, and the wheels or drums, always revolve in opposite directions
said wheels or drums being revolved on the shaft by the sliding frame or plate.
When the parts are thus connected it will be apparent that no matter in what
direction the frane or plate is moved, the shaft on which the power wheel is
mounted, will always be revolved in the same direction this movement thereof
being accomplished by means of the drums and ratchet wheels in connection

page_text: therewith and the pivoted pawls which are connected with said drums and which
are in connection with said ratchet teeth, together with the cords or other
devices which are connected with said drum and the central sliding frame of
plate.
It will be apparent that other devices may be substituted for the cords whereby
the drums or wheels may be turned or operated as herein described, a simple
device for this purpose being rack bars arranged at the top and bottom and on
opposite sides of the plate or frame, and adapted to operate in connection with

Improvements in Devices for Converting Reciprocating into
Rotary Motion.
We, JOHN HENRY NELSON, and ALBERT ELLIS FREETO, citizens of the
United States, residing at Roodhouse, in the County of Greene, and State of
Illinois, United States of America, Farmers do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to means for, converting horizontal or straight into rotary
motion; and the object thereof is to provide an improved apparatus for this
purpose, which is simple in construction and operation; and with this and other
object in view, the invention consists in the construction, combination and
arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which ;-
Fig. 1, is a plan view of my improvement; and,
Fig. 2, a side view thereof.
In the drawing forming part of this specification A represents a base plate
which is employed simply as a support for the construction which forms the basis
of our invention, and at the opposite sides thereof are placed two standards or
bearings a, in which is mounted a shaft a 2.
The shaft a 2, is provided at one end with a wheel B the inner side of which is
provided with a hub b, on which are formed ratchet teeth 62, and mounted on the
shaft a 2 adjacent to the hub b, is a wheel or drum D, provided with a pawl d,
which is adapted to operate in connection with said ratchet teeth on the hub b,
and secured to the side of said wheel or drum is a spring d 2, which bears
upon said pawl, and mounted adjacent to said wheel or drum D, is a sliding frame
or bar G, provided with a central oblong slot or opening, through which the
shaft a 2 passes, and adjacent to the frame or plate G, opposite the drum or
wheel D, is a similar drum or wheel H, and mounted on or secured to the
shaft, a 2, adjacent to the wheel or drum H; is a ratchet wheel K, and secured
to the drum or wheel H, is a pawi h, which is adapted to operate in connection
with said ratchet and a spring à 2, which bears upon said pawl.
The plate or frame G, is provided with an extension 93, which passes through
a keeper 94, secured to the base board or plate A, and said plate or frame G, is
free to slide back and forth between the drums or wheels D, and H, and mounted
on each of said wheel or drums D and H, is a cord chain or similar device L
the ends of which extends in opposite directions and are connected with arms M
which are secured to the plate or frame G, and it will be apparent the two of the

page_text: cords or chains L, may be employed in connection with each arum,
the same object may be accomplished by one.
desired, or
The ends of the cords or chains L, extend from the top of one of the drums to
the arms M, with which it is connected which are secured to, or formed on the
plate or frame G, near the bottom thereof, and the end of the cord or chain L,
connected with the other drum extend from the top thereof to the arms M, with
which they are connected, which are secured to or formed on the plate or frame G,
at or near the top thereof, and the wheels or drums D, and H, always revolve in
opposite directions said wheels or drums being revolved on the shaft a 2, by the
sliding plate or frame G.
When the frame or plate G, is moved in the direction of the arrow O, shown
in Figs. 1, and 2, the wheel or drum H, revolves in the same direction and by
rheans of the pawl h, and the ratchet wheel K, revolves the shaft a 2, and the
wheel b, in the same direction, and in this movement of the plate or frame G,
the wheel or drum D, turns backwardly, the ratchet b, thereon moving over the
ratchet teeth on the hub b, of the wheel B, and when the frame or plate G, is
moved in the opposite direction, or in the direction of the arrow O 2, the wheel
or drum H, again turns in the same direction the pawl h, moving freely over the
ratchet wheel K, but the wheel or frame D, turns in the reverse direction, and by
reason of the pawl d, also turns the shaft a 2, and the wheel B, in the same
direction, and thus the shaft a 2, and the wheel B, are always turned in the same
direction.
It will be apparent that other devices may be substituted for the cords L,
whereby the drums or wheels D, and H, may be turned or operated as herein
described, and a simple device for this purpose being rack bars arranged at
the top and at the bottom and the opposite sides of the plate or frame G,
and adapted to operate in connection with gear teeth formed on said drums or
wheels.
