arms 15 and 15' are carried by the valve 8,
the arm 15 will again be swung to the full
line position as seen in Fig. 1, and during
the movement of the arms 15 and 15', the
5 valve 28 will again be operated so as to par-
tially close off the flow of exhaust through
the pipe 21, for providing a cushioning ac-
tion upon the piston when it approaches the
end of its upward stroke.
10 From the foregoing, taken in connection
with the drawings, it.should be obvious that
as the wheels 17 and 17' are rotated in the
opposite directions, the tappet pins 25-25a
and 25'-25" will alternately engage and
15 swing the respective arms 15 and 15' of the
valve 8 for reversing the said valve auto-
matically. The number of tappet pins upon
the wheels 17 and 17' may be increased or
decreased as is necessary or desirable for re-
20 versing the valve 8 faster or slower. The
supplemental or auxiliary valve 28 is also
operated or reversed when the main valve
structure 6 is operated or reversed, to pro-
vide the cushioning effect at the opposite
25 ends of the cylinder to prevent a jarring or
pounding action of the piston as might oth-
erwise result.
The present apparatus is comparatively
simple and substantial in construction, and is
30 not liable to get out of order, or to require
special attention in its operation. The struc-ture is of advantage also for other obvious
reasons which need not be itemized.
Having thus described the invention, what
is claimed as new is:- 35
1. An automatic controller embodying an
oscillatory valve having a pair of arms, and
a pair of wheels rotatable in opposite direc-
tions and having tappets for alternately en-
gaging and swinging the said arms. 40
2. An automatic controller of the charac-
ter described, comprising a frame, a control-
ling valve structure carried thereby includ-
ing an oscillatory valve having arms at its
opposite sides and arranged at an angle rela- 45
tive to one another, opposite wheels carried
by the frame, the said arms projecting over
the sides of the wheels, the wheels having
tappet pins projecting therefrom for alter-
nately engaging and swinging the respective 50
arms to oscillate the valve to reversed posi-
tions, and a rotary driving member disposed
between and operatively engaged to the said
wheels and carried by the frame.
In testimony that I claim the foregoing as 55
my own, I have hereto affixed my signature
in the presence of two witnesses.
