IMPROVEMENTS IN EVER-POINTED PENCIL CASES
Year: 1877

page_text: LETTERS PATENT to William Edward Wiley, of Birmingham, in the County of
Warwick, for the Invention of "IMPROVEMENTS IN EVER-POINTED PENCIL
CASES."
Sealed the 28th August 1877, and dated the 12th March 1877.
PROVISIONAL SPECIFICATION left by the said William Edward Wiley at
the Office of the Commissioners of Patents on the 12th March 1877.
WILLIAM EDWARD WILEY; of Birmingham, in the County of Warwick. "IMPROVE
MENTS IN EVER-POINTED PENCIL CASES."
Heretofore when using a solid or unsplit point to an ever-pointed pencil case
great difficulty is sometimes experienced in obtaining leads properly to fit the saine.
The leads frequently fit so loosely as to be liable to fall out, or they frequently fit
so tightly as either to cause the breakage of the lead or injury to the "motion."
When using a split point to ever-pointed pencil cases, although the lead has been
securely held thereby, such split point was found liable to break. Now, according
to my Invention, I combine the advantages of both the aforesaid descriptions of
points and am thereby enabled to use, within certain limits, different sizes of leads
with the same pencil case and securely hold the same in the point whilst retaining
the advantages of a solid point to the pencil case.
In carrying my Invention into effect, I form the pencil case with a solid point and
with one or more internal springs (preferably three) bent or sprung so that their
outer ends press against the inside of the solid point near to the end thereof, whilst
such springs bend inwards or towards each other or the centre of the point at a
short distance from the end of the point so as to put an elastic pressure on the
lead.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Edward Wiley in the Great Seal Patent Office on the
12th September 1877.

page_text: And in order that my said Invention may be more crenity
carried into effect, I will proceed, aided by the accompanying Drawings, more fully,
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an exterior view of a pencil case point and parts connected therewith
having my improvements applied thereto; Figure 2 is a longitudinal sectional view
of the same without any lead therein; and Figure 3 is a similar view to Figure 2,
but representing a length of lead therein. All the views are drawn to an enlarged
scale in order the better to represent the parts.
a represents the point which is of the character known as a solid point, that is to
say, is not split but affords a solid support at its outer end to the lead. b are
springs which are bent or sprung so that their outer ends press against the inside
of the solid point near to the end thereof, whilst such springs are bent inwards or
towards each other or the centre of the "point," at a short distance from the end of
the point, so as to put an elastic pressure on the lead. These springs are represented
separately at Figure 4, and at Figure 5 I have represented a blank of a shape
suitable to be bent up into the form of a tube b¹, with three springs b at one end
thereof, as shown at Figure 4. The tubular part b¹ is soldered or otherwise fixed
at its rear end in the part c.
By the employment of springs b bent in the manner herein shown and described,
the lead is securely held in position in the point whilst no obstruction is offered to
the introduction of the lead into the point.
Having thus described the nature of my said Invention and the mode in which
I prefer to carry the same into effect, I would have it understood that what I claim
is, the employment of springs b in the interior of the "solid points" of ever-pointed
pencil cases, in manner and for the purpose substantially as herein shown and
described.
In witness whereof, I, the said William Edward Wiley, have hereunto set
my hand and scal, this Twenty-ninth day of August, in the year of our
Lord Oue thousand eight hundred and seventy-seven.
