are operating. This beam can be operated by
means of a friction-pulley and chain, or steam-
power, or other convenient mechanism, and is
kept from moving too far in either direction
by means of suitable stops, which engage with
the posts D D.
Directly beneath the carriage B is a frame,
O, one end of which is pivotally secured in
posts B B, which support the outer rail of the
track, and the other end rests upon the inter-
mediate portion of the wedge-beam K. The
free end of this frame is operated or lifted by
means of an inclined pawl, Q, the upper end
of which is pivoted to a support, 1R, upon the
beam K, and its lower end rests upon the top
of the beam. Upon the top of this frame O
is secured a cross-beam, S, having holes near
its ends. Within these holes loosely fit the
reduced ends of the arms of a throwing-bar,
T, the upper portions of which arms slide in
guides upon the sides of the ties of the track,
and the upper portion of the bar is parallel
with the track and can be made long enough
to extend any distance in front of the frame.
If desired, the lower ends of these arms can
be secured to the ends of the cross-beam S by
means of pivot-pins upon the ends of the beam
passing through holes in the lower ends of the
arms; or the frame can be made ofsuch a shape
as rectangular, for instance, and the lower
ends of the arms be secured directly to the
frame without the cross-beam, the object being
to cause the top of the bar to be raised when-
ever the pawl Q is forced under the free end of
the frame.
Secured to the carriage, at about midway be-
tween the head-blocks, are two parallel verti-
cal plates or bars, U U, between which, at one
end, is pivotally secured a trip, V, consisting
of a pieceof metal bent or folded at its middle,
and forming a slot or recess, W; or it can be
formed of a solid piece of metal and be pro-
vided with such aslot or recess. Near the mid-
dle of this trip, within the slot W, is pivoted
the upper end of a tripping-bar, X, the lower
end of which moves just above and is operated
by the throwing-bar T. The upper end of this
tripping-bar may be inclined and provided
with teeth, as shown at Y, if desired, which
engage with the lower side of thelog and pre-
vent it from slipping whilebeing turned. The
lower portion of this tripping-bar can be cut
away, as shown in dotted lines at Z; or the
carriage-frame can be cut away to permit of
the motion of the tripping-bar toward the side
of the frame, caused by its upper end moving
in the are of a circle with the trip V.
When it is desired to turn a log, it is released
from the head-blocks and motion is imparted
to the wedge-beam K. This raises the log-
catchers E E and the trip V simultaneously,
so that by the time the tops of the log-catch-
ers are even with the head-blocks,where they
are held by means of the flat portions of the
wedges L L, the trip V has moved up suffi-
ciently to roll the log from off the carriage
onto the inclined ends of the catchers. Thefree end of the frame then drops over the top
of the pawl Q, which permits the throwing-
bar T and the trip V to drop back out of the 70
way. By this time the edges M M upon the
side of the beam engage with the lower ends
of the loading-levers J J, which causes their
upper ends to bear against the log and force
it back upon the head - blocks against the 75
knees, the inclined ends of the catchers greatly
facilitating this work. The beam K is now
drawn back to its former position, the free end
of the frame O passing under the pawl Q to
its original position in front of the pawl, and 80o
the catchers E E,with the loading-levers, also
drop back into their original position; where
they remain until it is desired to turn the log
again, when the same operation is again -re-
peated. 85
By having the top of the throwing-bar T
made long enough to extend in front of the
frame A, the device will operate with the car-
riage at any point in which the bottom of the
tripping-bar X is above any portion of it, thus 9
avoiding the necessity of having to stop the
carriage at any particular place.
Instead of placing the wedge-beam parallel
with the track, as shown, two beams can be
used by placing them at right angles to it, 95
having one under each of the log-catchers, and.
the loading-levers can be operated by pawls
or latches the same as above described for
operating the tripping-bar, and for longer logs
additional log-catchers and tripping-bars may ioo
be provided by extending the frame and
wedge-beams.
Having thus described our invention, we
claim-
1. In a log-turner, the combination of two rc5
upright log-catchers adapted to move verti-
cally at the sides of the front posts of the mill-
frame, a loading-lever pivotally secured upon
one side of each of said catchers, a trip upon
the carriage, and a wedge-beam for operating r CI
said catchers, levers, and trip, substantially
as described, and for the purpose set forth.
2. In a log-turner, the combination of two
upright log-catchers adapted to move verti-
cally at the sides of the mill-frame, the upper Ir5
end of each of which is inclined or beveled
toward the carriage, a loading-lever pivotally
secured near its middle to the side of each of
said catchers and having its upper end pro-
jecting slightly above the upper end of said 120
catchers, a trip upon the carriage, and a wedge-
beam for operating said catchers, levers, and
trip, substantially as described, and for the
purpose set forth.
3. In a log-turner, the combination of two 125
upright log-catchers at the sides of the front
posts of the mill-frame, the lower portion of
each of said catchers being cut away, forming
shoulders upon their rear sides, a notch in the
rear side of each of said posts, a wedge-beam 130
adapted to be moved in said notches and hav-
ing two wedges at each end, one upon the top
of the beam and the other upon the side, a
loading-lever pivotally secured to the side of
