UNITED STATES PATENT OFFICE...
EVELYN onLA RUE, OF LONDON, ENGLAND.
' FOUNTAIN-PEN.
To all whom may concern: Be it known that I, EvnLrN on LA RUE, I asu'bject of the Kin of Great Britain, resid fiow, in the city of London, England have invented certain new anduseful Improvements in Fountain-Pens, of following is aspecification.
The object of-th1s invention is to rovide a fountain-penwhioh may be readily ii led without a separate filler by the aid of means con- According to this invention the pen is provided with a piston, which is normally retained at tTiT' rear end of the barrel, but which can be enga ed when it is necessary to fill the, pen by. the lead of a longitudinal rod which passes .out through the piston and the rearot the hand is soon red to a screw-cap. Prefcrab y the head of the rod is so formed as to act as a valve to shut oh the supply of ink to the nib when the pen is out of use.
A pen made according to this invention is drawings, of wh1ch Figure 1 is a longitudinal section of the pen with the parts in the )osition for writing. Fig. 2 is a section with t e rod drawn back to engage the piston, and Fig. 3 is a section with the plston in its forward position.
a is the barrel; 1) the rod which asses out through the rear end of the barre and terminates in a cap I), which normally screws onto the thread aand holds the rod in its for ward position.
c is the piston, which is normally retained, as shown in Fig. 1, by a pin or pins a, en-
on it is desired to fill the pen, the cap b is unscrewed and ulled rearward as far as ossible, when it is turned gently to the right Specification of Letters Patent. Application filed Augut 1,1905. Serill No. 272,143-
bayonet Patented March 18,1906.
until a pin or ins b upon the rod b engage a right-handed ayonet slot or slots 0 1n the piston. The cap is then pulled a little farthe-r to the rear and again turned to the right. The first art of the pins in the slots 0 and the remaining movement unlocks the pins atfrorn the slots 0'. The piston cannow be pushed forward b means of, the cap and rod until it is c locked by the stop a at the barrel, as shown in Fig. 3. The pen may now be'fillod as is an ordinary syringe, the ink being drawn up through the ducts supplying the nib.
in order to allow of the escape ofany ink '55 whiclrmay pass behind the piston, a small vent a may be drilled throngh the rear end of the barrel.
Preferably the head of the rod bis pro' vided with a valve 1;, which comes against a 60 seat d, formed in the nib-carrier d,'so that; by screwing the cap b up tight 'no inkcan. escape and the pen ma be carried in any po sition without fear 0 leakage. 'Wlienthe en is to be used, the cap I) must of course 65 e unscrewed more or less, accordingto'the flow of ink required.
What I claim is- In a fountain-pen, the combination of a piston, aloft-handed bayonet-fastening adapted 7o to retain it in the rear end of the barrel, a piston-rod contained in the barrel .and out through its rear end, and a right; ande -fastening for engaging the rod with the piston.
