FOUNTAIN-FEED DRAWING- PEN v Application filed October 15, 1928. Serial No. 312,413.

attachment of the barrel, or handle of the pen and the nib members thereof; 7

These and other objects and features of the invention will be fully described in the following specification and claims and illustrated in the accompanying drawings, in which: s Fig. 1 shows a side view of the pen. 'Fig. 2 shows a front View of same.

Fig. 3 shows, on an enlarged scale, a section on the line 3-3 of figure 1.

Fig. 4 shows, also enlarged,.a'section on the line 44 of" figure 3.

' Fig. 5 shows a plan view of the valve seat removed from the casing.

Referring first to figures 1 and 2 of the drawings; the principle elements of thepen are as follows: 8 v The valve sleeve 10, the barrelll and the nibs 12. The barrel has a screw cap 13 for filling and the nibs have the usual thumb adjusting screw 14. In operation; ink is released onto the distributor blade 15 by pressing on the button 16 the action of which will be described later.

Now, referring to figures 3, 4 and 5 of the drawings; it will be seen that the valve seat 17 is screwed into the sleeve 10 coming to rest at the point 18. It has a boss on its lower face which fits into a recess in the rotatable valve disk 19, the said recess being indicated by the dotted line 20. a

The disk 19 is securedby the bolt 21 whichv has a nut 22 thereon and a screw head 23 v at its lower extremity. A spring 2 1.1naintains a suitable pressure on the valve disk. An elongated hole, or duct 25 passes through the valve seat and permits the ink to flow from the reservoir 26 when the hole 27 of the j valve disk is in open alignment; j- Y Secured to the disk 19 in the manner illustrated in figure 4, is the push-rod 28 which, beingheld by the screw pin 29 passes through the slot indicated by the dotted lines 30 and through the spring clip 31 terminating in the button 16. A supplementary spring 32 augments the action ofthis rod. I When thecducts are closed, as is the case when the rod is fully out; the hole' 27 rests 0 ata pointin advance of the hole 25.

The elongated shape of the hole 25 as seen in fig ure 5, permits of a flow of ink for a longer period when the button is pressedthan would be the case if it were simply round as the 05- h0le-27. The holes 33 indicated in the valve seat pass only partly through the same and are for aid in assembling; a spanner being used for the purpose.

Thenibs 12 are secured to the plug 34 together with the distributor blade 15. This plug is screwed into the sleeve 10 and leaves clearance forthe rotating of the valve disk 19.

While the device is shown and described in its preferred form; it is understood that such minor changes may be made therein as may come within the spirit and scope of the appended claims. 1

Having thus described my invention, what Iclaim as new and desire to secure by Letters 30 Patent, is as follows: I

A reservoir valve comprising a seat within a sleeve and the said seat having a downwardly disposed boss thereon, a rotatable disk recessed to fitover the said boss and s5 secured in position thereon 'by means of a central bolt and a tension spring which bears against the bolt head and the base of the said disk, an elongated-holein the seat element and a perforation in the rotatable disk so which is adapted to be brought into alignment with the said elongated hole when actuated by a push rod which is pivotally attached to the said disk at an 011' center point of same and which rod is retractable by means of a spring located between the outer wall of the said sleeve and a button head on the said push rod.

Signed at New York in the county of New York and State of New York this 22nd day of September A. D. 1928.
