An Improved Reel and Chalk-line.
I, MARTIN NELSON, of Quincy, Massachusetts, U.S.A. Inventor, 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:-
The chalk-line recl of this invention, and which is more especially designed for
stone workers or cutters, in substance, is composed of a cylindrical and closed
casing or shell adapted to contain powdered chalk or other suitable material, and
having a packed throat or passage leading from its inner to its outer side, a skeleton
wheel located within and having its axle hung in bearings of the opposite sile walls
and at one end portion projected through and beyond the corresponding side wall of
the casing, and a line held on and passing from said wheel through said throat of
the casing, all so that the wheel, by the projected portion of its axle, can be rotated
from the outside of the casing and the line can pass into and out of the casing as
it is reeled and unreeled by said wheel, and otherwise, in combination with an arm
which is in two parts, at one end of each hinged together, and has one part at its
end opposite to its hinged end held on said projected portion of the wheel-axle, so
that the axle may freely turn in it, and has the other part at its end opposite to its
hinged end adapted when it is folded upon the part held on the wheel-axle, as
stated, to be engaged with said axle, and thereby the arm, as a whole, made a
handle to the axle for the convenience of turning it, and when opened out from the
part held on the wheel-axle, as stated, to be engaged with the casing, and thereby
made secure against movement in either direction of the turning or rotation of the
wheel.
Further than the above, the invention consists in the combination, with the casing,
of a brush which is detachably attached to and entered into it, and also in the com-
bination, with the line, of a flexible or pliable pad, which is confined, but is free
to move lengthwise on it, all substantially as and for the several purposes hereinafter
specified.
In the drawings forming part of this Specification,
Figure 1 is an exterior view of the casing of the reel and showing the chalk-line
as extending therefrom and having the flexible pad and a hook for engaging it, as
desired.
Fig. 2 is a section, on line 2 2, of Fig. 1.
Fig. 3 is a vertical section, on line 3 3, of Fig. 1.
Fig. 4 is an elevation of a block of stone, showing the line caught by its hook
thereon and the working of its pad in connection with the stone and line, as will
hereinafter appear.
Fig. 5 is a broken view of a block of stone and showing a straight-edge, the
working-edge of which has been previously prepared with chalk placed on the upper
face thereof, all as will hereinafter appear.
In the drawings, A A² are the opposite sides, and A³ is the edge or rim, and
severally made of any suitable material-for instance, sheet-brass or other metal-
and together constituting a closed cylindrical shell or casing of the reel of this
invention.
B and B are the opposite parallel sides, and B³ are the parallel rods, having
open spaces between and joining and held on said sides and severally arranged at
equal distances from the axis of the axle B', joining said sides, and as a whole
making a wheel that is disposed within and lies between and by its said axle is hung
to turn in bearings of the sides of the casing.
The wheel-axle at one end portion R³ nurients through and to and heyond the

page_text: outer face of the side A. of the casing. The wheel-sides B B have openings B6
through them, and the several parallel rods B3 together make a barrel or central
portion for the winding and unwinding of a chalk-line C, which is secured by tying
(not shown) or otherwise suitably to one of said rods.
D is a throat or passage through the rim A³ of the casing and at one
side of the reeling-wheel, and the chalk-line as it is wound and unwound from
said wheel, running over a guide-roller D³ of the casing, passes through this
throat.
E is a thickness of leather or other suitable packing material applied to and held
on the rim of the casing by a plate E and screws E³, and lying over and across
the throat or passage of the casing, and this leather has a continuation D³ of
.said passage, and of some suitable diameter relative to the chalk-line to serve as a
packing thereto and the throat D of the casing, and thus prevent the escape of the
powdered chalk (shown at F, Fig. 3) or other suitable material with which the
casing is charged for suitably preparing or coating the chalk-line therewith as
the line is reeled and unreeled in use.
G G2 is an arm in two parts, and having one part G at one end by a screw-mut a
applied to the projected portion of the axle of the recling-wheel, held on and loosely
surrounding said axle, so that the axle may freely turn in it, and at the other end
hinged, as at b, to the other part G2, which has a square-siled opening to engage,
when it is folded over and upon the part G, as shown in dotted lines, Fig. 3, the
square sides of the nut a of said axle, and also has an arm, swivelled on its outer
end, and when the part G2 is opened out from the part G to lie against the rim of
the casing. With the part G of the arm G G2 engaged with the wheel-axle, as
explained, the arm as a whole makes a handle to said axle for convenience in
turning it, and through it the wheel to wind the line onto the wheel, and with the
arm of the part G2 of the arm G G lying against the rim of the casing the arm
is secured against turning with the wheel as it turns in reeling the line off of the
wheel.
H is a brush held on a head-block H2, which is adapted to be screwed into and
out of the casing and inserted, as stated. The brush projects into the powdered
contents of the casing for being charged therewith, and thus adapted for the use for
which this brush is provided-to wit, for chalking with it the working-edge g of a
straight-edge J, so that placing said edge on the face of a stone K, Fig. 5, desired
to be finished with a smooth and even face, the projecting and irregular portions
of said face will be marked by the chalk and so indicated as to insure their final
removal by the stone-worker and the securing of the desired smoothness and
eveness of the face of the stone.
L is a hook of right-angular shape secured and hung on the outer end of the
chalk-line C, and to be used for engaging the line, as, for illustration, Fig. 4, with
the under side of a stone M, and thence running the line up one side N of the stone
to and around the corner or edge O, made by it and the top face P of the stone,
and from this corner along the top face of the stone to be chalk-lined by holding
and snapping the chalk-line, all as well known.
Qis a flexible and pliable pad, made of leather or other suitable material and
having an car-piece Q, by which it is held on the chalk-line, so as 'to be free 'to
be moved therealong. In the running of a chalk-line as just explained, and as
illustrated, Fig. 2, this pad is to be placed about the corner or edge of the
stone for the chalk-line to run over it, and thus it serves as a guard to the line, and
by preventing its contact with said corner or edge it obviates the possibility of its
being cut or otherwise injured thereby as the line is held and snapped; as well
known.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare,that.what I
claim is:-
