TECIFICATION,
I DANIEL BUCKLEY of Boston, in the County of Suffolk, State of Massa-
chusetts one of the United States of America Mechanic do hereby declare the
nature of my Invention for EXTENSION LEVERS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention relates to 'that class of levers which are extensible and designed
more especially for plumbers' use in connection with water-closet tanks, and also
for supporting their work in any desired position; and it consists in a novel
construction and arrangement of the parts as hereinafter more fully set forth, by
which a more effective and desirable article of this character is produced than is
now in ordinary use."
The nature and operation of the improvement will be readily understood from
the following explanation, the extremo simplicity of the device rendering an
claborate description unnecessary.
In the accompanying Drawing
Figure 1 is an isometrical perspective view of my improved lever ;
Figure 2 is a side clevation of the same;
Figure 3 is a top view or plan.
Figure 4 is a vertical transverse section taken through the bearing or support;
and
Figure 5 a perspective view of the journal detached.
Similar letters of reference indicate corresponding parts in the several Figures.
A, B indicate the arms or sections of the lover and C the fulcrum or support.
The arms are each provided with an elongated slot running nearly the entire
length of its body.
The arm A is provided at one end of its slot x with a laterally projecting stud d
and at its opposite end with a laterally projecting, stud m, the lever B being
provided with two corresponding laterally projecting studs i.
A screw-bolt D, provided with the nut E is used to journal the levers in the
support C. This bolt is flattened on either side, as shown at t, the flattened
portion being drawn into the slot x of the arm A when in use, and the head or
rounded portion of the bolt resting in the standard e of the support when
in use,

page_text: The nut E is elongated and provided with a round body V which rests in the
standard when the nut is turned in fully, as best seen in Figures 1, 2 and 3.
In the use of my improvement the arms are placed side by side as shown in
Figure 1 with the stud 'm on the arm A inserted in the slot of the arm B and
one of the studs i on the arm B inserted in the slot z of the arm A. The screw
of the bolt D is then passed through the holes in the upper portion of the
standards ef until the flattened portion t has entered the slot in the arm A, after
which the nut E is screwed onto the bolt until the arins A B are firmly clamped
between the nut and head of the bolt, and the portions = V rest in their respective
bearings in the standards e f
It will be obvious that when the levers are tilted or tipped the journal will be
turned in its bearings in the support O by means of the flattened portion t insorted
in arm A, and also that the arms will be kept in alignment by the studs which
project into the slots.
The arms of each are provided with a hole rat either end through which screw-
bolts may be passed provided with nuts for attaching auxiliary levers to eithor of
the arms, and thereby longthening them as required.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
First. In a device substantially such as described, the arm A provided with
the slot and studs m d, and the arm B provided with the slot x and studs i, in
combination with means for clamping said arms together and journalling or pivotting
them, substantially as described.
Second. In a device substantially such as described, the screw-bolt D provided
with the round elongated head and flattened portion t, in combination with the
nut E having the round elongated body V for journalling and clamping the
arms A, B, substantially as set forth.
-
Third. In a device substantially such as described, the standard C provided
with the bolt D, and nut E adapted to clamp and journal the arms A, B,
substantially as described.
Fourth. The improved extensible lever heroin described, the same consisting of
the arm A provided with the slot the studs d, m and the holes r, the arm B
provided with the studs the slot x and the holes 7, the screw bolt D having the
rounded head and the flattened portion t, the nut E having the rounded body V,
and the support C provided with the standards ef, all constructed, combined and
arranged to operate substantially as set forth.
Fifth. In a device substantially such as described, the arms A, B provided with
the holes for attaching auxiliary arms to lengthen the lever, substantially as
described.
