Year: 1874

page_text: LETTERS PATENT to William Edward Wiley, of Birmingham, in the
County of Warwick, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF MOVEMENTS FOR PENCIL CASES AND OTHER ARTICLES HAVING
SIMILAR MOVEMENTS.'
Scaled the 17th November 1874, and dated the 5th June 1874.
PROVISIONAL SPECIFICATION left by the said William Edward Wiley
at the Office of the Commissioners, of Patents, with his Petition,
on the 5th June 1874.
I, WILLIAM EDWARD WILEY, of Birmingham, in the County of
Warwick, do hereby declare the nature of the said Invention for
" IMPROVEMENTS IN THE MANUFACTURE OF MOVEMENTS FOR PENCIL CASES AND
OTHER ARTICLES HAVING SIMILAR MOVEMENTS," to be as follows:-
The Invention has for its object improvements in the manufacture of
movements for pencil cases, toothpicks, and other articles having similar

page_text: movements, and relates, firstly, to a novel mode of forming the screw or
part known as the "coil box." For this purpose, instead of forming the
screw or "coil box" by coiling a wire and soldering such wire inside a
tube as heretofore, I take a narrow strip of metal having one or more
grooves formed therein, preferably by cutting, but such groove or grooves
may be otherwise formed; or instead of employing a grooved strip such
strip may be of a T section. Strips of metal formed as above described
are coiled on a suitable mandril or spindle when the thread of the screw
is formed by the grooves or projections on the strips.
The Invention relates, secondly, to improvements in the construction of
the "
propellor" to work within the screw or "coil box," so as to retain
the "hook" of the "propellor" within the worm of the screw. For this
purpose, I form the "propellor" with a spring bearing against the
interior of the conducting tube within the screw or coil box
on the
opposite side to that of the "hook." This arrangement also has tho
advantage of enabling the "propellor" to be pushed into the screw or
"coil box" from the back after the "coil box" has been fastened up.
"
.The Invention relates, thirdly, to improvements in what is known as
the "automatic movement," which is employed for pushing out the last
portion of the lead from the "propellor." For this purpose, I employ
two "propellors" of the character before described, side by side, or one
above the other, the one propellor having a portion working within the
tube holder of the other.

page_text: of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Edward Wiley,
Her special license that I, the said William Edward Wiley, my
executors, administrators, and assigns, or such others as I, the said
William Edward Wiley, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for “IMPROVEMENTS IN THE MANUFACTURE OF MOVE-
MENTS FOR PENCIL CASES AND OTHER ARTICLES HAVING SIMILAR MOVEMENTS,"
upon the condition (amongst others) that I, the said William Edward
Wiley, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Wiley, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Drawings
hereunto annexed, and to the figures and letters marked thereon, that is
to say:
-
The Invention has for its object improvements in the manufacture of
movements for pencil cases, toothpicks, and other articles having similar
movements. For this purpose, instead of forming the screw or "coil
box" by coiling a wire and soldering such coil inside a tube as heretofore,
I take a narrow strip of metal having one or more grooves formed
therein, preferably by cutting, but such groove or grooves may be other-
wise formed.
At Figures 1 and 2 I have represented a section and side view of a
strip of metal a, such as I prefer to employ for this purpose, such strip -
having a single groove a¹ formed therein by cutting; or instead of
employing a grooved strip such strip may be of a T section, such as that

page_text: °
shown by Figure 3. Strips of metal formed as above described arc
coiled on a suitable mandril or spindle when the threads of the screws
are formed by the grooves a¹ in or projections a² on the strips a. At
Figure 4 I have represented a longitudinal section of a screw or "coil
box" constructed as above described of a strip of metal of the form į
shown at Figures 1 and 2.
'
The Invention relates, secondly, to improvements in the construction
of the "propeller" to work within the screw or "coil box," so as to
retain the "hook" of the "propeller" within the worm of the screw.
For this purpose, I form the "propeller" 6. as shown at Figures 5, 6, 1
and 7, with a spring b¹ bearing against the interior of the conducting
tube c within the screw or coil box d on the opposite side to that of the
hook. This arrangement also has the advantage of enabling .the
"propeller 6 to be pushed into the screw or coil box d after the "coil
box" has been fastened up.

]
The Invention relates, thirdly, to improvements in what is known as
the "automatic movement," which is employed for pushing out the last
portion of the lead from the "propeller." For this purpose I employ,
as shown at Figures 8, two "propellers "b, e, of a similar character to
that before described, side by side, or one above the other, the one 2
propellere having a portion working within the tube holder 63 of the
other; or the propeller 6 may be formed entirely of a tube, and the
propeller e may be solid, as shown at Figure 9, in which case the
hooks and e¹ will stand in opposite directions to each other.
Having thus described the nature of my said Invention, and the mode 2
in which I carry the same into effect, I would have it understood that
what I claim is,-
First. The novel mode of forming the screws or "coil boxes" of
pencil cases and other articles having similar movements, substantially
as herein shown and described with respect to Figures 1, 2, 3, and 4.
"
Secondly. I claim the novel mode of constructing the "propellers
of pencil cases and other articles having similar movements, sub-

page_text: And, Thirdly. I claim the novel mode of constructing what is known
as the "automatic movement" of pencil cases, substantially as herein
shown and described with respect to Figures 8 and 9.
In witness whereof, I, the said William Edward Wiley, have
hereunto set my hand and seal, this First day of December,.
in the year of our Lord One thousand eight hundred and seventy-
four.
