PROVISIONAL SPECIFICATION.
Improvements in Line Chalking Apparatus.
I, CARL ENGELBERT ANDERSON, of Woods Holl, Barustable County, State of
Massachusetts, United States of America, Gardener, do hereby declare the nature
of this invention to be as follows :-
My invention relates to apparatus for conveniently holding and keeping in a
cleanly and compact way the chalk line used by carpenters, gardeners, and other
artizans, and automatically supplying the same with chalk in a uniform and regulated
quantity.
The apparatus consists of a box divided by a partition into two separate
compartments, the one adapted to contain the chalk line which is wound on a spool
which is journaled in bearings in the sides of the box and provided with a crank
handle and the other to receive powdered chalk. The latter chamber is
narrowed at its bottom by inclined boards, so as to form a hopper or V-shaped
receptacle which causes the chalk always to feed down to the middle of the bottom
of the box. In the top of the partition there is an elongated slot in which is fixed
a shaft, upon which rotates a broad-faced concave guide pulley or roller.
roller carries the cord as it passes from the spool over into the chalk chamber, and
as the cord plays back and forth in its spiral lay upon the spool this guide roller is
permitted by the length of its axis to move back and forth to accommodate itself
to the cord.
This
After the cord passes over the pulley it descends nearly to the bottom of the
chalk chamber and passing around a similar roller rises again and passes over a
roller in the front wall of the box and emerging through the same, is connected to
a ring carrying a sharpened pin or peg by which its end may be connected to any
point when in use, the ring permitting it to be hooked over a nail screw or other
projection, when in use and to prevent the line from being drawn entirely into the
box, while the sharpened peg permits the line to be attached to a wall, the surface
of the earth, or other plane surface. The roller in the bottom of the chalk
chamber is journalled directly in the walls of said chamber whose convergence at
the bottom is sufficient to permit this. As the chalk line rises from the roller, and
the mass of chalk powder, all surplus chalk which may adhere is scraped off by a
loop bar or scraper.
In adapting my device to the use of gardeners where the chalking of the line is
not necessary, the roller at the bottom of the chalk chamber is made detachable
so that the line need not pass through the chalk at all, and for this purpose the
sides of the chalk chamber are grooved with a dovetail channel down to the
journals of the roller and dovetail slides are inserted in these channels and beld
down by the lid of the box. These slides hold the roller down in its bearings in
the sides and yet they may be easily and quickly removed to allow the roller to
be removed when it is not required to be used.

I, CARL ENGELBERT ANDERSON, of Woods Holl, Barnstable County, State of
Massachusetts, United States of America, Gardener, 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 :—
My invention relates to apparatus for conveniently holding and keeping in a
cleanly and compact way the chalk line used by carpenters, gardeners, other
artisans, and automatically supplying the same with chalk in a uniform and regulated
quantity.
It consists in the peculiar construction and arrangement of parts of the device,
which I will now proceed to more fully describe, with reference to the accompanying
drawing, forming part of this Specification, in which
•
Figure 1 is a perspective view of the exterior of the box or casing.
Figure 2 is a plan view, with the cover removed.
Figure 3 is a vertical section, taken through line 3-3 Figure 2.
Figure 4 is a vertical section taken through line 4-4 Figure 2.
Similar letters of reference in the several figures refer to the same parts.
In the drawing A represents a box or casing made preferably of wood and of a
size adapted to the length of the chalk line used. This box has a hinged cover A³
with a suitable fastening a and has also a handle h² for convenience in
transportation.
.
This box is divided internally by a partition A³ into two compartments A' A².
The compartment A' is the larger of the two, and in it is journaled in suitable
bearings in the side of the box a reel or spool B, upon which is wound the chalk
line C by means of crank handle b. The other compartment A² is designed to
receive the powdered chalk and is narrowed at its bottom by inclined boards A* A,
see Figure 4, so as to form a hopper or V-shaped receptacle. This causes the
chalk always to feed down to the middle of the bottom of the box so that the last
remnants of chalk may be effectively applied to the cord and used up, even when
but a small quantity is in the box.
In the top of the partition A is formed an elongated slot in which is fixed an
axial shaft à upon which rotates a broad faced concave guide pulley or roller D.
This roller carries the cord as it passes from the spool B over into the chalk
chamber, and as the cord plays back and forth in its spiral lay upon the spool this
guide roller is permitted by the length of its axis d to move back and forth to
accommodate itself to the cord.
After the cord passes over pulley D it descends nearly to the bottom of the
chalk chamber and passing around a similar roller H rises again and passes over a
roller F in the front wall of the box and emerging through the same, is connected
to the ring I carrying a sharpened pin or peg G by which its end may be connected
to any point when in use, the ring I permitting it to be hooked over a nail screw or
other projection, when in use and to prevent the line from being drawn entirely
into the box, while the sharpened peg G permits the line to be attached to a wall,
the surface of the earth, or other plane surface.
The roller H is journaled directly in the walls A* A* of the chalk chamber whose
convergence at the bottom is sufficient to permit this.
As the chalk line rises from roller H and the mass of chalk powder & all surplus
chalk which may adhere is scraped off by a loop bar or scraper E, so that it does
not foul the box or its surroundings in passing out.

page_text: I am aware that a chalk box having a spring roller within the same to wind up
the line, and a chalk chamber adjacent to it through which the line passes and is
chalked has been heretofore used, and I therefore only claim my peculiar construc-
tion and arrangement of parts, which is much simpler and cheaper, and is not liable
to get out of order as do these spring actuated rollers whose springs frequently get
so weakened in power as to fail to take up and rewind the line.
In adapting my device to the use of gardeners where the chalking of the line is
not necessary, the roller H is made detachable so that the line need not pass
through the chalk at all and for this purpose the sides A* A* of the chalk chamber
are grooved with a dovetail channel down to the journals of roller H and dovetail
slides h h are inserted in these channels and held down by the lid of the box.
These slides hold the roller down in its bearings in the sides A' and yet they may
be easily and quickly removed to allow the roller to be removed when it is not
required to be used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a line chalking apparatus having two compartments, the one for the chalk
line and the other for the chalk, the combination with the two compartment box ;
of a spool or reel arranged in one compartment, the chalk line wound thereon, an
axis d arranged in the top part of the partition, and a guide roller arranged in the
partition between the two compartments and made laterally adjustable on said axis
to accommodate itself to the spiral lay of the line on the spool substantially as and
for the purpose described.
2. A line chalking apparatus consisting of a two compartment box, one
compartment of which is made V-shaped at the bottom and is adapted to receive
the chalk, and the other of which is provided with a spool or reel, guide rollers
arranged respectively in the partition between the compartments and the bottom of
the V-shaped chamber, and the chalk line wound about the reel and descending to
and passing around the roller in the bottom of the V-shaped chalk chamber
substantially as and for the purpose described.
3. In a line chalking apparatus, the combination with the compartment for
chalk; of a guide roller for the line arranged in the bottom of said compartment
and means for locking said roller there or removing it substantially as shown and
described.
4. In a line chalking apparatus, the combination of grooved walls A* A*, the
roller H, and retaining slides h h substantially as and for the purpose described.
5. A line chalking apparatus consisting of a two compartment box, one
compartment of which is made V-shaped at the bottom and is adapted to receive
the chalk, and the other of which is provided with a spool or reel, guide rollers
arranged respectively in the partition between the compartments, in the bottom of
the chalk chamber, and the external wall of the box, and the chalk line passing
over the rollers in the partition and box wall, and under the roller in the bottom of
the chalk chamber substantially as shown and described.
6. A line chalking apparatus consisting of a two compartment box, a chalk line,
a spool or reel arranged in one compartment, rollers for guiding the chalk line into
the chalk of the chalk chamber, and a scraper arranged inside the chalk chamber
just above the level of the chalk to bear against the chalk line as it emerges from
the chalk to dislodge the surplus chalk and avoid fouling the box and its surroundings
substantially as shown and described.
7. The combination of the box A having two compartments with laterally
adjustable rollers D D in the partition between the compartments, the spool B
arranged in one compartment to receive the line, roller H arranged in the bottom
of the chalk chamber, roller F arranged in the side of the box, and the chalk line
wound about the reel and over the guide rollers and having attached outside the

page_text: box a ring I with sharpened peg or pin G substantially as and for the purpose
.described.
