at the Office of the Commissioners of Patents, with his Petition, on the
2nd April 1862.-A communication from abroad by Eugene Recordon,
of Vaison, Vaucluse, France.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEMORANDUM, POCKET, AND OTHER BOOKS, AND IN PENCIL
AND PENHOLDERS TO BE USED THEREWITH," (communicated to me from abroad by
Eugene Recordon, of Vaison, Vancluse, France,) to be as follows:-
The first part of this Invention consists in making the covers of memo-
randum, pocket, and other books of a material such as slate or other mineral
or plastic substance capable of receiving writing, and which may be removed
when desired by washing, or otherwise. One side of the book is composed
for example of a sheet of natural or artificial slate held on three sides in a
metal frame carrying hooked gudgeons. To the back of the book a metal
band is attached, beneath which the fourth side of the slate is slid; the ends of
the band are bent to form slides, in which the two hooked gudgeons take, and
thereby render the frame solid with the band; by this means a fresh slate may
be inserted when the old is used or broken. The other side of the book is
made of cardboard, wood, leather, or other material, carrying in the centre a
metal frame, in which a sheet of natural or artificial slate is placed, or both
sides of the book may be made alike.

page_text: The improvements in pencil and pen and ink holders, are as follows:-
The ink holder is screwed on at one end of the case, and the pen holder
acts as a stopper to it. A socket inside the case is screw threaded at
each end to receive either a black lead or a slate pencil, the pen holder is
made hollow to contain a box for leads. A holder simply for lead and slate
pencil is also made according to this Invention, which will be best understood
by reference to the accompanying Drawings.
Figure 1 is a longitudinal section of it complete, and Figures 2, 3, and 4
are views of its component parts. The holder consists mainly of two tubes,
Figures 3 and 4, the first n, of which terminates in a conical point p, pro-
longed from the screw-threaded tube n; a collar r on a tube s, Figure 2, is
screwed on the bottom of the tube n, and has a rectilinear motion imparted
to it by means of a stud t, free to slide in the grove o of the case. To the
collar a tube u screw threaded externally is fitted, the other end of the tube
is closed, and carries the two rods v, ac, for pushing out the lead or slate
pencil. The second tube, Figure 4, screws at one end on to the tube u, the
other end terminates in a conical point m, which as well as the point p is
split at its point to act as a spring, and grip the lead or pencil; q is a tube
surrounding the others. The part p takes the lead points, and m takes the
slate pencil points. By turning the part p the collar r descends or ascends,
the screw-threaded tube n drawing the tubes with it, but as the tube u, which
carries the rods v, a, is fixed to the collar a, they become more or less pushed
into the parts p or m, according to the direction in which they are turned, so
that the point of the lead or slate pencil is presented as required.
