COMPLETE SPECIFICATION.
Improvements in Chalk Lines and Reels.
I, GUSTOF ERIK JOHNSON, of 212 East 127th Street, in the City, County and
State of New York, United States of America, Carpenter, do hereby declare the
nature of this invention and in what manner the same is performed to be
particularly described and ascertained in and by the following statement:-
This invention relates to carpenters' reels, and the object thereof, is to provide a
device of this class, on which is mounted a chalk line which may be unwound or
wound up in the manner of an ordinary measuring tape; a further object being to
provide a device of this class, so constructed and arranged that the line will be
automatically chalked as it is withdrawn from the reel; and with this and other
objects in view, the invention consists in the construction, combination and
arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, in which ;-
Fig. 1, is a transverse vertical section of my improved reel;
Fig. 2, a side view thereof;
Fig. 3, a similar view of a frame or reel on which the line is wound; and,
Fig. 4, a view similar to that of Fig. 2, showing the opposite side.
In the practice of my invention, I provide a circular casing A, which is similar
in form to that of an ordinary tape reel and passing through said casing, centrally
thereof, is a shaft B, provided at one side with a projection b, to which is pivoted
the usual plate D, provided at the centre of one face thereof, with a button or
head d, and formed in the adjacent side of the casing A, is a depression F, which
corresponds in form to the plate D, and in the central portion of which is a
supplemental depression adapted to receive a head or button d.
Mounted on the shaft B is a spider frame or reel G, composed of a central
tubular head g, and radical arms g', said ratical arms being arranged at each end of
the tubular head g, and being outwardly inclined from said head on each side, as
clearly shown in Fig. 1, and secured to the head g, of said reel, is a line H, which
is adapted to be wound thereon, and the free ends of which is adapted to be passed
through a perforation or opening h, in the perimeter of the casing A.
In practice, I place within the casing A, a quantity of chalk preferably in the
condition of a powder, and this chalk is inserted into said casing through a hole K,
in the side thereof, opposite the pivoted or hinged plate D, and this hole k, is closed
by a plate L, which is held in position by a nut M.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing. The line being wound on the
head g, of the reel G, and the chalk being placed within the casing A and the
opening K, closed by the plate L, all that is necessary when it is desired to use
the chalk line is to withdraw the same from the casing in the manner of an ordinary
measuring tape, and the line in this operation, will be chalked as will be readily
understood.
The plate D, or the head or button d thereon, serves as a handle, for winding up
the line, and it will be understood that the reel G, is secured to the shaft B, and
revolves therewith.
It will thus be seen that I accomplish the object of my invention, by means of a
simple and effective device, and one which is comparatively inexpensive.

page_text: 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. A chalk line reel comprising a circular casing within which is mounted a shaft
which is revoluble therein, a reel mounted on shaft and adapted to revolve
therewith, a line or cord mounted on said reel and projecting through a hole or
opening in the perimeter of the casing, and means for revolving said wheel and said
shaft, substantially as shown and described.
2. A chalk line reel comprising a circular casing within which is mounted a shaft
which is revoluble therein, a reel mounted on said shaft and adapted to revolve
therewith, a line or cord mounted on said reel and projecting through a hole or
opening in the perimeter of the casing and means for revolving said wheel and said
shaft, the said casing being provided with an opening in one side thereof, through
which the chalk may be inserted thereinto, and said opening being adapted to be
closed, substantially as shown and described.
3. A chalk line reel comprising a circular casing within which is mounted a shaft
which is revoluble therein, a reel mounted on said shaft and adapted to revolve
therewith, a line or cord mounted on said reel and projecting through a hole or
opening in the perimeter of the casing and means for revolving said wheel. and
shaft, the said casing being provided with an opening in one side thereof, through
which the chalk may be inserted, thereinto, and said opening being adapted to be
closed by a plate mounted on said shaft, substantially as shown and described.
