OTTO BUSSLER, OF NUREMBERG, lAvARIA, GERMANY.
STYLOGRAPHlC PEN.
SPECIFICATION forming part of Letters Patent No. 350,037, dated September 28, 1886,
Application filed April T, 1885. Renewed Angustld, 18%. Serial No. 211,068. (No model.)
To all whom it may concern:
Be it known that I, OTTO BUssLER, of Nuremberg, Bavaria, Germany, have invented a new and useful Stylographic Pen, of which the following is a specification.
This invention relates to copyingink pencils or stylographio fountain-pens.
In describing the invention reference will be made to the accompanying drawings, Fig- 11 res I to III, of which Figs. I and II are longitudinal sections of a pen embodying my invention, while Fig. III represents a detail.
Theimprovement chiefly consists in a device for protecting the point, and in the arrangement for adjusting the pencil for use.
Hitherto the device for protecting the point 8 and the ink-reservoir I, connected with the same, merely consisted in a sleeve adapted to be pushed over the point, which arrangement is not sufficient to protect the point 8 against impurities.
The copying-pencil embodying this invention is provided with an automatic perfectlyact-iug device for protecting, and at the same time holding, the point.
The invention consists in the application of a divided clamp, 7;, adapted to close completely, in combination with the point e of the inkreservoir, provided with a recess (or a swelling or projection) for the combined purpose of protecting the point when not used and holding the same when used.
The apparatus is constructed as follows:
tis the ink-reservoir, moving freely in the interior and completely independent from the surrounding sleeve. The reservoir contains a pencil passing through its whole length and provided with a piston and spring for the automatic feed of the ink.
g is the india-rubber disk, serving to close the upper end of the ink-reservoir when the pen is not in use. Vhen used, the pencil is pushed back, the indie-rubber disk is lifted and admits air, whereby the ink is discharged at the lower end in the usual manner. The
shaped teeth e, mounted near the lower end of the tube It. \Vhen closed, this clamp completely covers the point .s'. This operation is effected automatically by the spring which constantly tends to draw the tube r, with clamp 7:, into the tube It.
For using the copying-pencil, the point is held downward and the tube r is pushed down into the tube It. By holding the point downward the movable ink-reservoirl falls downward. By t-hepressu re on the tube r the clamp k is pushed out and disengaged from the ends of the tube hand opened by the teeth 6, so that the ink-reservoir I can freely advance (until it reaches a suitably-situated stop) so as to protrude from the clamp L. The point a is provided with recesses i, or a lateral detent, (collars or projections, etc in which the clamp it engages when the pressure at the upper end (on tube 1' and spring f) ceases, whereby the copying-pencil is arrested and held fast.
\Vhat I claim is The combination of a movable ink-reservoir having recesses i, or a lateral deteut, with an expansible clamp, la, adapted to either close together in front of the point of the reservoir or to engage with the recesses i, or detent of thesame, for the purpose of holding the reservoir in position when in use and protecting the point when not in use, substantially as de scribed.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
OTTO BUSSLER.
