PEN.

To all i/zom i! may concern.'

Be it known that we Roni-:RT PIERPONT STARKEY and GEORGE (LAYTON RATHBUN, both citizens of the United States, and residents, respectively, of San Francisco, in thel county of San Francisco and State ot' California. .have invented a new andlmproved Pen, of which the following is a full, clear, and exact description.

This invention relates to improvements in pens and particularly to lettering or drawing pens. an object of the invention being to provide a pen of this character having an ink reservoir and to provide improved means for keeping the ink from drying in thc reselvoir so that it is unnecessary to lill and clean the pen each time it is used.

A further object is t0 provide a pen which is readily adjustable relative to its holder so that the user may incline the pen holder at any angle' and the pe-n will still be presented in upright position on the paper.

A still further object is to provide a pen of this character practical in construction, neat and attractive in appearance and durable and efficient in use. It is also an object of the invention to provide an improved attachment for the pen which will act as a spacing member when the pen is used in connection with a T-square or other device having a ruling ed e.

1llVith these and other objects in View the in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

resents the fount of the pen. The fount is of cylindrical shape tapering at its lower end and intel-nali)v threaded adjacent its upper end- An apertured lug 2 projects laterally from the fount 1 adjacent its lower end.

The pen holder metal sleeve 3 into one end of which any appropriate handle member 4 is fitted. The other end of the sleeve is closed and a bifurcated member 5 is made integral therewith. The arms of the bifurcated member are perforated and receive the ape'rtured lug 2 between them. A screw 6 and thumb nut 6 are used to pivotally connect the lug 2 and the member 5 so that the pen is pivotally connected to its holder.

. A threaded cap 7 screws into the upper end ot the fount. The cap is formed with a vertical air passage or vent 8, the inner end of which is enlarged as indicated at 9 to receive the upper end of a spring actuated plunger 10. A member 11 including an annular series ot outwardly and :upwardly flaring arms is ixedly connected to the intermediate portion of the plunger. At its lower end the plunger 10 is provided with a reduced portion 12 constituting the stylus of the pen. The stylus is movable through an ink duct 13 in the lower end of the fount. A shoulder 14 around the plunger just above the stylus is held against the walls of the inner end of the ink duct by a coiled spring 15 located around the plunger 10 between the cap 7 and the member 11.

The shoulder 14 thus functions as a springheld valve. lVhen the stylus is pressed against the paper it compresses the spring 15, forces the upper end of the plunger 10 into the enlarged portion 9 of the vent 8, unseats the shoulder 14 from its position against the inner end of the ink duct 13 and allows ink to flow through the duct around the stylus. When the pen is lifted olf the paper the spring will automatically restore the parts to their normal position closing the ink duct.

In Figure 5 I have illustrated my improved spacing attachment applied to the pen. The spacing attachment comprises an annular ring 16 fitting over the fount. A vertically disposed straight edged member 17 is made integral with the ring and is adapted to engage the ruling edge of a T- square or similar device 18. A depending preferably comprises a the fount, a vertically bifurcated portion 19 integral with the ring 16 straddles the lug 2 and prevents circumferential or downward movement of the ring relative to the fount. 4

It will be readily seen that the pen will always be in vertical position relative to the paper while the pen any angle to suit the individual preference of the user.

With the ordinary drawing or letter pens commonly employed, it is necessary to clean /and fill them every time they are used. My

improved pen is always ready for use since the valve mechanism prevents drying or caking of the ink.

Various slight changes and modifications might be made in the general form and arrangement of the parts described without departing from the spirit of the invention, and hence I do not limit myself to the precise details set forth but shall consider myself at liberty to'make such slight changes and `from the fount, apen holder may be tilted at cluding a`fount, a spring held stylus in the fount, an apertured lug extending laterally holder including a bifurcated end portion straddling the lug and pivotally connected thereto and a spacing member including a ring fitting over the fount, a lvertically disposed straight edged member integral with the ring and means preventing circumferential movement of the ring relative to the fount, said means comprising a bifurcated member depending from the ring and straddling the ug.

3. In a pen a cylindrical fount tapering and having an ink duet in its lower end, a

cap fitting into the open end of the fount,.

said cap having a vent therein, the inner end of said vent being enlarged, a spring held plunger, a stylus carried by the lower end of the plunger and movable in the ink duct, the upper end of said plunger being movable in the enlarged portion of the vent and a shoulder aroundthe plunger limiting the movement of the stylus in the ink duct and normally closing said duct.

4. In a pen, a fount, a stylus in the fount, an arm extending laterally from the fount, a pen holder connected to the arm, a ring around the fount, a vertically disposed straight edged spacing member integral with the ring, means carried by the ring straddling the arm and preventing circumferential movement of the ring relative to 4the fount.
