IMPROVEMENTS IN PENCILHOLDERS
Year: 1885

page_text: I, HERBERT JOHN HADDAN, of 67 Strand, in the city of Westminster, Civil
Engineer, do hereby declare the nature of said invention for IMPROVEMENTS IN
PENCILHOLDERS, a communication to me from abroad by the firm of Helmreich &
Dinkelmeier, Manufacturers, of Nürnberg, in the Kingdom of Bavaria, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
These improvements relate to pencil holders and will be described with the aid
of the annexed drawings Figs. 1. to 10. The blacklead tube a, of which Fig. 1 is
a front elevation and Fig. 2 a side elevation, is provided at its lower end with a
shoulder a¹, which has two openings a², serving as bearings for an axle b, adapted
to act like an eccentric. The axle b, of which Fig. 3 is a plan and Fig. 4 an
elevation, has a recess b¹ and is furnished at its ends with flat pivots b², projecting
from the openings a² of the shoulder. The rear part of the blacklead tube a,
bearing on the collar a³ the spiral spring c, is surrounded by the depressing tube or
pusher d. The depressing tube d, of which Fig. 5 is a front elevation and Fig. 6
a side elevation, is cut out at the lower end, so as to form two tongues d, each of
which is provided with a hinge piece e or link, having a longitudinal opening e¹.
As shown by Figs. 7 and 8, the flattened pivots 62 of the axle b are introduced into
the said openings, so that the axle is connected with the pusher by the said links.
The outer casing f is soldered on to the lower end of the blacklead tube a.
the pusher has been connected with the axle, it is lifted by the pressure of the
helical spring c, and the axle b'is turned. When by pressure on the tubed this
tube and the axle b is brought into the position, shown by Fig. 8, the blacklead
can pass freely in the tube a through the recess 6 of the axle b. When the
blacklead is lying on the axle, as shown by Fig. 8, and the pressure on the tube d
ceases, the latter, as shown by Fig. 7, is lifted by the spring c, and the axle b is
turned. Thereby the blacklead is pressed against the inner wall of the tube a and
clipped or held fast so as to be fit for use. If subsequently the axle b is again
brought into the position, shown by Fig. 8, by pressure on the tube d, and the
After

page_text: blacklead allowed to slide back into the tube a, beyond the reach of the axle b,
the latter when the pressure ceases, is turned by the spiral spring c a little further
than shown by Fig. 7, and thereby the opening of the tube a is narrowed opposite
the axle b, so that the blacklead is no more allowed to pass along the axle and
therefore remains in the rear part of the tube a, when the holder is not in use.
Fig. 9 is a cross section of Fig. 7 along line A-B, and Fig. 10 a cross section of
Fig. 8 along line C-D.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
In a pencil holder:
1. The axle 6 supported or guided in a shoulder a¹ of the tube a and connected
with the tube d by links e, the said axle being adapted to act like an eccentric,
when turned by the helical spring e, and thereby to clip the blacklead, when the
latter is within the reach of the axle; and when the blacklead is situated in the
tube a, beyond the reach of the axle, to narrow the bore of the tube a in such a
manner, that the blacklead cannot pass the axle.
2. The combination of pencil tube a, with axle b, spring c, pusher d, links e
casing f and pencil g, substantially as and for the purpose described.
