35 of the friction wheel 9, and anti-frictional
balls 36 are disposed above ind below the
ring 34 to reduce friction. The arm 33 is
provided between its ends with a threaded
5 portion or half nut 37 to engage the screw
29, and the arm has a handle 38 at its free
end. A clamping member 39 is pivoted as at
40, between its ends to the' arm 33 between
the half nut 37 and handle 38, and is pro-
10 vided at one end with a threaded portion or
half nut 41 complementing the half nut 37
to :also engage the:screw and provide a nut
embracing .the screw to be moved thereby.
The -member 39 -is provided at its. other end
15 with-a. handle.42 -complementing the handle
38, a spring 43 separating the handle 38 and
42,.whereby to move the'half nuts 37 and 41
together. into ;engagement with the screw.
In operation,-'the shaft 1 being rotated,
20 will rotate the shaft 6 and friction wheel 9,
which transmits. motion to the cone 10 and
parts driven thereby. A screw 29 is also ro-
tated. by:the shaft 1, thereby moving the
nut comprising the half nuts 37--41 down-
25 wardly, and the.arm 33 will therefore move
the friction wheel downwardly with it,
thereby gradually reducing the speed of ro-
tation of :the cone 10. When the parts have
completed their .:movement, the friction
30 wheel 9 can. be restored readily to starting
position, .by grasping the. handles 38-42
and swinging them toward each.other, which
will:separate the half-nuts 37-41, and the
arm 33 can then be swung to remove the
35 half nut 37 .from the screw.. At the same
time, .the arm 331can be pulled slightly, to
pull the -shaft .6 with the bearing 24 away.
from the cone, thus relieving the pressure
of the friction;wheel against the cone under
40 the.influence. of the spring 26, and the spring
27 will then raise 'the. shaft 6. -'When the
parts have been returned to starting posi-tion, by releasing the handles 38-42, the
spring 26 will again move the shaft 6 to-
ward the cone bringing the friction wheel 9 45
into. contact therewith, and the spring 4:;
will move the half nuts together so as to
embrace the screw. The mechanism ,is then
in starting position for a new operation.
Having thus described the invention, what 50
is claimed is:-
1. A mechanism of the character de-
scribed, embodying a cone, a friction wheel
mounted to bear against and move .along
said cone, spring means for pressing the 55
wheel against the cone and returning said
wheel to starting position, :a screw, and a
device embodying an arm connected at one
end with said wheel and having .a handle at
its other end and a half-nut between its 60
ends to engage said screw,.-and a member
die complementing the+aforesaid handle.
pivoted.between its.ends to said arm between
said handle and half nut and: having a half
nut, at one end to complement said half nut, 65
the other end of said member having a han-
2. A mechanism of the :character de-
scribed, embodying a cone, a friction wheel
mounted to bear against and move along
said cone, means.for returning the wheel to 70
normal position,;a screw, and a device .em-
bodying 'an arm connected at one end:with
said wheel and having a half-nut.between
its-ends to engage said screw, and a member
pivoted' to said arm and. havinga half-nut 75
at one end complemental to the first-men-
tioned half-nut.
In 'testimony that I claim the foregoing as
my own, I have hereto affixed my:signature
in the presence of two-witnesses..
