Be it known that I, RoBRT W. J. SMrrrH,
a citizen of the United States, and president
of Huntsville, in the county of Walker and
" State of Texas, have invented certain new
m A sf!r rmproveinents in Mechanism for
Converting Reciprocating into. Rotary Mo-
tion, of which the following is a specifica-
ti on.
1o My invention is an improvement in mech-
a:nism ifor converting reciprocating into ro-
tarv motion, and has for its object the pro-
vision of a simple device of the character
speciied for connecting a driving shaft with
z:: one or more driven shafts, in such manner
'ut while the driven shafts are continuously
rotated by the driving shaft, the relative
speed of 'the driven shafts with respect'tbo
Ihe driving shaft may be easily and quickly
20 changed.
In the drawings: Figure 1 is a plan view
of the improvement, partly in section; Fig.
2 is a side view.
In the present embodiment of the inven-
25 tion the main or driving shaft I is provided
with three open rectangular frames 2-3 and
4. each of which is formed integral with the
sha ft, the long axes of the frames coinciding
with the axis of the shaft. Cams 5-6 and 7
30 are mounted on the frames, each cam having
a slot. S for receiving the frame, and the slots
S are of greater length' than the width of the
irane i)pon which the coin is mounted.
A yoke 9 is engaged by each cam, each
'> yoke having a rectan giropening 10, in
whiichthe cam is arran ed, and the cam
I oiucles oplosite sides of the opening,so that
when the coin rotates the yoke is reciprocated
ranisverselv of the shaft. All of the yokes
40 are reciprocated in the some direction, and
each has a driving (oniection With the lt-
eral or driven shafts 11 and 12, arranged on
opposite sides of the shaft 1.
A ratchet wheel 13 is secured to each shaft
45 11 and 12, in a rectangular opening 14, in
the yoke. and each ratchet wheel is engaged
l)v a pjluraliIv of series 15 and 15a of teeth.
'lih series of teeth are oppositely arranged,
one series being on each side of the ratchet
50 wheel, and of the opening 14, and all of the
said teeth are mounted to slide toward and
from the longitudinal axis of the yoke.
The teeth of each series are slidanle in
openings 1r in the yoke, and a bar 17 is held
55 against the shoulders of the teeth of each
series, each bar being arranged transverselyof the teeth of the series. An arched spring
18 bears against the bar 17, at approximately
the center thereof and each spring acts nor-
mally to force the teeth inwardly. 60
The inner end of each, tooth of series 15 is
beveled or inclined on its lower face, as
shown at 19, while the inner end of each
tooth of series 15a is beveled or inclined on
its upper face, as shown at 20. The arrange- 65
ment of teeth and ratchet wheel is such. that
when the yoke moves toward the shaft ad-
jacernt to the teeth, the teeth of series 15a
engage and rotate the wheel, while the teeth
of series 15 are pressed outwardly. On the ro
other hand when the yoke moves toward the
opposite shaft, the teeth of series 15 engage
and rotate the wheel, while the teeth of
series i5a are pushed outwardly. A (ontinli-
ous movement in one direction is thus im- 75
parted to the- two shafts 11 and 12, when
shaft l"is rotated.
Each of the cams 5, 6 and 7 is provided
with a pin 21, arranged transversely of slot
8, at the point of eccentricity of the carr, and 80
each pin 21 passes through a slot 22, ex-
tending- diagonally of a block 23. Each
block 23 is slidable in the frame on which
the cam is mounted, longitudinally of shaft
1, and it will be evident that when the block 85
is moved .the cam belonging thereto will be
shifted to increase or diminish its eccen
tricity.
The shaft 1 is hollow, and a rod 24 is ar-
ranged "in the hollow at one end of the shaft. 90
The inner end of rod 24 is connected to the
block 23 of cam 5, and the outer end of the
rod is provided with a head 25, having an
annular groove 26. A lever 27 is pivoted in-
termediate its ends, as shown at 28, and the 95
inner end of the lever is forked, the arms 29
of the fork having pins or rollers 30 engag-
ing the groove 2 of the head. The outer
end of the-lever is provided with a grip 31,
and it will be evident, that when the lever is 100
swung. the block 23 will be nloved in the
frame 2. The block 23 of frame 2 is con-
nected to the said block of frame 3, and the
block of frame 3 is connected to the block of
frame 4, by. means of rods 32, both rods be- 1o5
ing in the hollow of shaft 1. When the lever
is swung, all of the blocks 23 are moved lon-
gitudinally of the shaft, and all of the cams
are shifted simultaneously, to increase or
diminish their eccentricity. Since the travel 110
or speed of shafts 11 and 12 with respect to
shaft I is dependent upon the eeeremdicity1,063,839.
