Improvements in Hand Levers for Lumbermen.
We, JAMES MARK ELLIS, and GEORGE LUCAS ELLIS, both residing at
Galesburg, in the County of Kuox, and State of Illinois, U.S.A. Gentlemen do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention has relation to cant hooks or dogs for lumbermen, and the object
is to provide a simple, cheap and convenient device of this kind that can be adjusted
to logs of different sizes; and to this end the novelty consists in the construction,
combination and arrangement of the same as will be hereinafter more fully describe [
and particularly pointed out in the claims.
In the accompanying drawings the same letters of reference indicate the samo
parts of the invention.
Figure 1 is a perspective view of our improved cant hook or dog;
Figure 2 is a longitudinal section; and
Figure 3 is a transverse section of the saine.
1 is the handle or lever, and 2 is a metallic strap encompassing the handle, and
secured thereto by a bolt 3 passing through the ears or lugs 4-4 of the strap, and
through a hole in the handle, which securely clamps the strap to the handle
and prevents the strap from turning sidewise or slipping up or down on the handle.
The outer ends of the ears 4-4 are provided with a bolt 6 which passes through
them, and it forms the fulcrum for the lever-hook 7, the lower end 8 of which is
formed with an orifice 9, to which is secured one end of a spiral spring 10, the
other end of which is secured to a hook 12, having a pin 12 which engages the
coils on the end of the spring.
A plate 13 lies flat on the plane side 14 of the handle 1, and is secured thereto
by a hook 15 riveted to the plate and passing under the bolt 3, and its trout end 16
forms an anvil 17, on which the lower front angular toe 18 of the lever hook 7
strikes, and which serves to limit the forward play of the hook.
A set screw 19 is secured in the handle 1, and its end comes in contact with the
under side of the forward end of the plate 13, which can be adjusted outwardly by
the set screw, as shown in dotted lines in Fig. 2, to regulate the play of the
angular toe 18 of the lever hook to correspond to the diameter of the logs being
handled.
20 represents a sheet metal casing, which encloses the spiral spring and protects
it when the cant hook is in use.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A cant hook or dog comprising a handle provided with a plane side and a bolt
hole, in combination with an encompassing strap secured thereto by a bolt passing
through said bolt hole, and having its ears or lugs provided with a bolt on which is
fulcrumed a lever-hook, formed with a front angular toe, and an anvil plate secured
to the plane side of the handle, and formed with an integral hook to engage one
end of a spiral spring, the other end of which is secured to the lower end of the
léver hook opposite its toe, substantially as and for the purpose set forth,

page_text: 2. A cant hook or dog comprising a handle having a plane side 1'4' and a
transverse hole 5, and an adjusting set screw 19, in combination with the strap 2,
bolts 3 and 6, on the latter of which is fulcrumed the lever-hook 7 having an
angular toe 18, and provided with a spiral spring 10, one end of which is secured
to the hook 12 on the plate 13, the forward eud of which forms an anvil for the
angular toe 18.of the lever-hook 7, substantially as and for the purpose set forth.
3. A cant hook or dog comprising a handle l'having a plane side 14, an adjusting
screw 19, and a transverse hole 5, in combination with the strap 2, bolts 3 and 6,
the latter of which forms a fulcrum for the lever-book 7, the plate 13 provided
with hook 12 passing around the bolt 3, and having a hooked end to which is
secured the spiral spring 10 connected to the lever-hook 7, substantially as and for
the purpose set forth....
