tion, the lifting finger rides under the guide
immediately above the guide over which it
has just passed, the plate 53 rising to per-
mit the finger to pass but dropping to the
5 lower bracket 55 as soon as it clears the
finger so that upon the next working move-
ment, the described lifting action will be re-
peated.
it is thought the advantages of my im-
10 proved leaf turner will be readily under-
stood from the foregoing description, taken
in connection with the accompanying draw-
ings without further detailed reference to
the same and it is to be understood that
15 changes may be made in the minor details of
construction or arrangement of parts with-
out involving any departure from the spirit
or scope of the invention as the same is de-
fined in the following claims.
20 Having thus described the invention, what
is claimed as new is:
1. In a leaf-turning apparatus, the com-
bination of a support mounted to swing in
a horizontal plane, hangers fixed to and de-
25 pending from said support, a leaf carrying
arm mounted for rocking movement in the
said hangers below the support, leaf-engag-
ing jaws fixed to said arm to rock therewith,
and resilient jaws secured to said hangers
30 and depending therefrom past the arm to
hear against and cooperate with the first-
mentioned jaws to secure a leaf.
2. In a leaf-turning apparatus, a support
arranged to swing in a horizontal plane, a
35 leaf-carrying arm mounted for rocking
movement on said support, a jaw fixed to
said arm, a resilient jaw secured on the sup-
port and extending over the first-mentioned
jaw to cooperate therewith, and a lug on the
40 first-mentioned jaw bearing upon the resili-
ent jaw whereby to hold the jaws together
upon a leaf to be carried, or separated to per-
mit the insertion or withdrawal of a leaf.
3. The combination of a plurality of leaf-
45 carrying arms, a vertically disposed pintle
rod, a pair of actuating members, one dis-
posed above and the other below one of the
leaf-carrying arms, the upper actuating
member being adapted to engage the upper
50 sides of the arms successively and the lower
actuating member being adapted to engage
the lower sides of the arms successively, rock
shafts loosely mounted upon the pintle and
secured, resepectively to the said actuating
55 members, means connected with said rock
shaft to swing the same independently.
and means for effecting vertical movement
of the rock shafts to bring each actuating
member into engagement with the successive
60 leaf-carrying arms.
4. The combination with a plurality of
leaf-carrying arms, of upper and lower
actuating members arranged to engage said
arms, rock shafts connected with the respec-
65 tive actuating members and mounted for in-dependent rotation, the rock shaft connected
with the uppermost actuating member be-
ing provided, with a sleeve supporting the
lower end of the rock shaft connected with
the lower actuating member, and means for 70
actuating said rock shafts whereby the actu-
ating member connected respectively there-
with will successively engage the leaf-carry-
ing arms.
5. The combination of a plurality of leaf- 75
carrying arms, a vertical series of spaced
guides disposed in rear of said arms, upper
and lower actuating members adapted to en-
gage the leaf-carrying arms, rock shafts con-
nected respectively with the said members, 80
means acting on said rock shafts to inde-
pendently rotate the same, the rock shaft
connected with the upper actuating member
supporting the rock shaft connected with
the lowertactuating member, and a lifting 85
finger projecting laterally from the last-men-
tioned rock shaft and adapted to ride upon
the said guides successively, the guides and
the finger being relatively inclined to effect
vertical movement of the rock shaft and 90
raise the actuating members to act upon suc-
cessively higher leaf-carrying arms.
6. The combination of a pintle, a plural-
ity of leaf-carrying arms supported for
movement about said pintle in horizontal 95
planes, a second pintle spaced from the first
pintle, a rock shaft consisting of upper and
lower cranks mounted to slide upon and ro-
tate about the second pintle and a post con-
necting said cranks, a second similar rock 100
shaft having its cranks disposed between the
cranks of the first-mentioned rock shaft,
means connected with the lower ends of the
said rock shafts for rotating the same inde-
pendently, and two members fixed to the up- 105
per ends of the respective rock shafts and
adapted to move in horizontal planes one of
said members carrying means to engage over
the leaf-carrying arms successively to move
the same in one direction and the other of 110
said members carrying means to engage
under the leaf-carrying arms successively to
move them in the opposite direction.
7. The combination of a plurality of leaf-
carrying arms, a vertical series of spaced 115
vertically movable guides disposed in rear
of said arms, upper and lower actuating
members adapted to engage the leaf-carry-
ing arms, rock shafts connected respectively
with the said members, means acting on said 120
rock shafts to independently rotate the same,
the rock shaft connected with the upper
actuating member supporting the rock shaft
connected with the lower actuating member,
and a lifting finger projecting laterally from 125
the last-mentioned rock shaft and adapted
to ride upon the said guides successively, the
guides and lifting finger being relatively in-
clined whereby upon movement of the finger
in one direction the guides will yield and 130
