IMPROVEMENTS IN PENCIL CASES, AND OTHER SIMILAR ARTICLES
Year: 1874

page_text: LETTERS PATENT to Michael Henry, of Fleet Chambers, 68, Fleet
Street, in the City of London, Patent Agent, for the Invention of
“IMPROVEMENTS IN PENCIL CASES, AND OTHER SIMILAR ARTICLES.”—A
communication from abroad by Alonzo T. Cross, of Providence,
Rhode Island, in the United States of America.
Scaled the 29th January 1875, and dated the 9th October 1874.
PROVISIONAL SPECIFICATION left by the said Michael Henry at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1874.
I, MICHAEL HENRY, of Fleet Chambers, 68, Fleet Street, in the
Oity of London, Patent Agent, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN PENCIL CASES, AND OTHER SIMILAR
ARTICLES," communicated to me from abroad by Alonzo T. Cross, of
Providence, Rhode Island, in the United States of America, to be as
follows:-
This Invention relates principally to screw pencil cases, and it is also
applicable to other similar articles, such as penholders, combined pen
and pencil holders, and toothpicks.

page_text: Hitherto in constructing screw pencil cases, and the like, the screw
mechanism has been soldered or otherwise permanently attached to the
tube which surrounds it, and hence the screw arrangement is not
accessible or available for repairs. Now this Invention has for its object
to remedy this evil and to allow of the repairing of the screw arrange-
ment. For this purpose instead of permanently attaching the screw
apparatus to the outer tube, I fit them together in such manner that
they are separable and capable of ready detachment when necessary or
desirable.
One mode of accomplishing this object is to provide the screw with a
friction sleeve, ferrule, bush, or collar, and the slotted internal tube with
a milled tip or neck of slightly less diameter at one part, so that a nice
adjustment is obtained. On the outer tube or case is another sleeve,
ferrule, bush, or ring, forming a stop to the screw in its inward travel.
The friction between the ferrules holds the screw apparatus and the outer
tube or case together.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Michael Henry in the Great Seal Patent Office
on the 7th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL
HENRY, of Fleet Chambers, 68, Fleet Street, in the City of London,
Patent Agent, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of October, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Michael Henry, Her special licence
that I, the said Michael Henry, my executors, administrators, and
assigns, or such others as I, the said Michael Henry, 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

page_text: The friction between the ferrules holds the screw apparatus and the
outer tube or case together.
In another arrangement or modification the milled tip or neok is held
frictionally, and the screw is worked by a stud or pin engaging in a
groove or slot in the outer tube.
I now proceed, with reference to the accompanying Drawings, to
describe more fully the mode of carrying the said Invention into effect,
shewing it applied by way of example to a pencil, though it is evident
it may be applied in like manner to other similar articles.
Figure 1 is an elvation of the pencil complete; Figure 2, sectional 1
elevation; and Figure 3, elevation of the screw mechanism detached.
from the case or outer tube.
A is a screw on which is soldered a friction sleeve, ferrule, bush, or
collar B. C is a slotted tube on which is a milled tip or neck D,
attached by solder or otherwise to the slotted tube C. The exterior 1
diameter of this sleeve or ferrule B is slightly greater than that of the
cylindrical portion of the milled tip or neck D, so that when the screw
mechanism is passed or slidden into the forward or upper end of the
tube or case E, the sleeve, bush, or ferrule B makes a tight fit with the
outer case or tube. At the end of the case or tube another sleeve, bush,
or ferrule F is fitted tightly or contracted around its periphery, and is
soldered at the part marked fin order to form a stop for preventing the
screw mechanism from being inadvertently pushed or slidden too far
within the case. The frictional contact caused by the bushes, sleeves, or
ferrules B and F will securely hold the screw mechanism and the outer
tube or case together.
Figures 4 and 5 shew an arrangement in which the improved screw
pencil mechanism is combined with an extension pen case. In these
Figures the screw apparatus is held in place in a manner similar to that
indicated in Figures 1, 2, and 3, and explained in the description referring
thereto. The screw mechanism may be withdrawn for cleaning or
repairing purposes.
Figures 6, 7, and 8, show in elevation (Fig. 7 being in section) a
modification of the above-described pencil case. In this modification
instead of using a sleeve, bush, collar, or ferrule B, as in Figures 1, 2,
and 3, the tip or milled end D is held in place by frictional contact

page_text: or means, and the screw A. is worked or operated by a feather pin,
stud, or spline a which enters a groove or slot formed in the surrounding
tube.
The screw pencil mechanism so constructed may be easily withdrawn
or removed from the outer case or tube E, as shown in Figures 1, 2,
and 3.
Any ordinary mode of connecting tubes together so that they shall
be readily detachable without injury or trouble may be employed as a
mechanical equivalent for the frictional means herein-before described.
.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim as my In-
vention of improvements in pencil cases and other similar articles, a
pencil case or other similar article in which the parts are constructed,
arranged, and combined, substantially in the manner and for the purpose
herein-before described.
In witness whereof, I, the said Michael Henry, have hereunto set
my hand and seal, this Sixth day of April, in the year One
herein-before described.
In witness whereof, I, the said Michael Henry, have hereunto set
my hand and seal, this Sixth day of April, in the year One
thousand eight hundred and seventy-five.
