page_text: Rotary or Rotary into Reciprocating Motion.
We, FRIEDRICH THEODOR JULIUS SCHNEIDER and CARL RUDOLPH WERTH, both
of Lothringer Strasse 35 Berlin, in the Empire of Germany, Engineers, do hereby
declare the nature of the said invention and in what manner the same is to be
performed, to be particularly. described and ascertained in and by the following
statement:-
The object of this Invention, is to convert reciprocating into rotary, or rotary into
reciprocating motion.
The Invention consists of the following parts, the construction and arrangement
of which we will describe. A disc provided with teeth on part of its circumference is
fixed on a shaft and works, or is worked, turned, by a piston rod provided with an
oblong loop having teeth on each side into which the teeth on the disc gear, when in
motion, transmitting in this way the stroke to, or from the piston.
In the annexed Drawings there is represented a device according to this Invention
for transmitting. motion to, or from a piston.
In Figures 1 and 2 the device is shown working the piston, or plunger of a pump.
In Figure 1 the device is shown at the bottom stroke and in Figure 2 at the top
stroke.
In Figure 3 there is shown a steam cylinder and piston arranged to rotate a shaft
by means of the device.
The disc a is provided with teeth con less than half its circumference, which teeth
gear with corresponding teeth c on the inside of the loop d. The width at of the
loop d is equal to the diameter of the disc a and the top and bottom of the loop d are
round to correspond with the disc a. The loop dis part of, or worked by the piston
rode and the length of the loop d at g h is equal to half the circumference of the
disc a.
In operation when the device is in the position shown at Figure 1 the plain portion
of the disc a fits into the semi circular curve at the top of the loop d and if the disc a
is turned in the direction of the arrow I then the teeth c of the disc a will gear into
the teeth c on the left side of the loop d and will raise the loop and piston rod e.
CIT

page_text: When the disc a has turned 180° it will be in the position shown at Figure 2 with its
teeth c in position to gear with the teeth c on the right side of the loop d and on
turning further the disc a will force down the loop d and piston rode to the position
shown in Figure 1. Owing to the fact that the disc a turns between the two sides
TT
of the loop d, a length of stroke is obtained which is expressed by of the diameter
of the disc a. The circumference of the disc a is fitted with teeth in such a manner,
and the teeth on the loop are so arranged that the two outside teeth of the disc a
gear at the same time into the loop d; thus a continuous motion is assured without
any dead point.
The device may be arranged to work. either vertically, or horizontally as shown in
the Drawings.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
A device for transmitting motion consisting of a disc a having teeth c, a loop d
having teeth c into which the teeth.c of the disc a gear, constructed and operating as
described and a piston rod, as set forth.
