UNITED STATES PATENT OFFICE-
ELI CATLIN, OF POST OAK, TEXAS.
DEVICE FOR CONVERTING MOTION.
EPECIFICATION forming part of Letters Patent No. 292,471, dated January 29, 1884.
Application fied November 19, 1883. (No model.)To call whom it n~cay concern:
Be it known that I, ELI CATLIN, a citizen
of the United States, residing at Post Oak, in
the county of Jack and State of Texas, have
5 invented a new and useful Device for Con-
verting Motion, of which the followingis a speci-
fication, reference being had to the accompa-
nying drawings.
This invention relates to devices for con-
io verting the reciprocating motion of the pis-
ton-rod in steam-engines into a rotary motion,
and for operating the valv.e-gear; and it has
for its object to produce mechanism which
shall be simple, easily applied, and by which
15 unnecessary expenditure of power shall be
avoided, as will be hereinafter fully described,
and particularly pointed out in the claims.
In the drawings hereto annexed, Figure 1
is a perspective view of my invention as ap-
20 plied to a steam-engine. Fig. 2 isa planview
of the same. Fig. 3 is a longitudinal vertical
sectional view. Fig. 4 is a vertical transverse
sectional view on the line x x in Fig. 2.
The same letters refer to the same parts in
25 all the figures.
A in the drawings designates the base or
frame which supports the cylinder B, having
valve-chest C, of ordinary construction.
D is the main shaft, which is journaled
30 transversely in the frame B, and which car-
ries the fly-wheels E E andpinions or toothed
segments F F', which latter are mounted
loosely upon the said shaft, so that they may
revolve in either direction.
35 Secured firmly upon the shaft D, adjoining
the outer sides of the pinions F F', are ratch-
et-wheels G G', that engage pawls or dogs H
H', pivoted to the sides of the pinions F F',
and having springs I, which bear against the
40 teeth of the said ratchet-wheels, thus holding
the pawls in engagement therewith.
J designates the piston-rod, which is pro-
vided at its outer end with a frame, K, the
upper and lower sides of which are composed
45 of rack-bars L L', engaging the pinions F and
F', respectively. It will be seen that when
the piston-rod moves in an outward direction
it serves to revolve the pinion F, which,through
its adjacent ratchet-wheel, serves to transmit
50 a rotary motion to the main shaft upon which
it is mounted, while the pinion F' revolves
without influencing the shaft. When the pis-ton-rod moves inward, the operation is re-
versed, and motion is transmitted to the main
shaft through the pinion F2 and its adjacent 55
ratchet-wheel.
Supported upon the frame A are suitable
uprights, Mf, which carry a pair of longitudi-
nal beams, N and 0, arranged one above the
other, as shown. The said uprights are also 6o
provided with bearings for a longitudinally-
sliding rod, P, the rear end of which is piv-
otally connected with a lever, Q, pivoted to
the frame near.the cylinder, as shown. Piv-
oted to the said rod P are two pairs of levers, 65
RR and S S'. The levers R andS have slots
s, working upon pins p upon the lower frame-
beam, N, and the levers 1 and S' are pro-
vided with slots r, working on pins t upon
the upper frame-beam, 0. The frame K is 70
provided with a laterally-projecting pin, T,
adapted to strike and operate the lever R'.
The lever S2 is operated by the inner end of
the frame K, and the upper side of the said
frame is provided with a pair of pivoted 75
latches, U U, facing in opposite directions,
and held in a raised position by means of
springs V V, so as to operate the levers R and
S when the'frame K reciprocates.
The operation of this invention will be read- 80
ily understood from the foregoing description,
taken in connection with the drawings hereto
annexed. The lower end of the hand-lever Q
is connected pivotally with the valve-stemn W
of thesengine. When the piston-rod recipro- 85
cates,it conveys,through the mechanism here-
in described,a rotary motion to the main shaft.
When the piston-rod, with the frame K, moves
in an outward direction, and has nearly com-
pleted its stroke, the pin T of frame K will go
strike the lower end of the lever R', thus start-
ing the rod P and partly reversing the valve.
The motion, however, will be too quick and
sudden to completely reverse the valve, and
the reversion of the position of the latter will 93
be completed by the action of one of the spring-
latches U against the lever R, under which.
the said latch has slipped on the outward
stroke of the piston-rod. When ,the piston-
rod completes its inward stroke,the operation io
is repeated, with the exception that the levers
S and S' are operated or acted against for the
purpose of reversing the valve.
This invention is simple, and may be ap-
