RESERVOIR PEN Filed April 6, 1929 Patented Mar. 11,- 1930 UNITED" STATES THEODOR KOVACS, 0F HANOVER, GERMANY RESERVOIR PEN Application filed April 6, 1929, Serial No.
My invention relates to reservoir pens. It is an object of my invention to provide certain improvements in connection with a reservoir pen. 7
More particularly my invention relates to the feed bar of the reservoir pen. It has already been proposed to provide a feed bar in the shape of a plug arranged below the nib, and to provide chambers for the reception of excess ink in the side of the feed bar which is opposite the nib. These chambers should be connected as directly as possible with the flow of ink to the pen in the vicinity of their ends which are pointing downward when writing and they should be connected as directly as possible with a passage returning the ink to the reservoir'at their. ends which are in downward position when the pen is held with the nib up. Besides they should have such capillary action as is required for holding the ink which has penetrated into the chambers until the ink is 'delivered to the point of the nib or returned to the reservoir.
More particularly, it is an object of my invention to fulfil these requirements by ex-, ceptionally simple means and so as to dispense with covering parts of metal as required in other cases for increasing capillary action. To this end I provide in the side of the feed bar which is remote from the nib narrow and deep grooves arranged substantially in parallel to the axis of: the holder and extending along that part of the feed bar which projects from the barrel, and preferably extending for some distance back into the mouth of the barrel. The grooves are so narrow that'they will retain the ink unless it is delivered to the nib or returned to the reservoir, as described.
Grooves of the type described, being closed at the bottom, exert a more intense capillary action than through slots which are open at both sides, and the ink does not dry up as readily in them as it does in open slots.
The grooves according to my invention may be arranged in parallel to the symmetry plane of the feed bar, that is, the central plane of the nib, or at right angles tosuch plane. With parallel arrangement they are prefer- 353,027, and in Germany April 11, 1928.
ably extended as far as the pointed end of the feed bar and in this manner are .connected directly with the flow of ink toward the nib.- If arranged at right angles to the plane of symmetry they may be connected with the capillary grooves by bores of known type and of such small area as not to allow aii to' pass when the bores are filled with in In the drawings ai'llxed to this specification and forming part thereof two types of feed bars embodying my invention are illustrated diagrammatically and to a magnified scale by way of example.
In the drawings Fig. 1 is a sectional elevation of the front end of a feed bar with the nib inserted between the bar and the barrel,
Fig. 2 is a section on the line 22 in Fig. 1, the feed bar illustrated in these two figures having its longitudinal groovesextending in parallel to the symmetry plane,
Fig. 3 is an elevation of the front end of a feed bar'having longitudinal grooves extending at right angles to the symmetry plane,
Fig. 4 is a section on the line 44 in Fig. 3.
Referring now to the drawings, and first to Figs. 1 and 2, A is the end of the barrel, which is flared at A, B is the feed bar and C is the nib. The barrel and the nib are inserted together in the openin of the barrel A. D is an air channel in the feed bar B which is covered by the nib, and E are the usual capillary grooves for conducting the ink in the bottom of the air channel. At either side of the channel D the usual side chambers F are provided. G are narrow and deep longitudinal grooves in that side of the feed bar which is remote from the nib, the grooves extending in parallel with the plane of symmetry. These grooves start within the end of the barrel A and extend through the projecting part of the feed bar B as far as the point of the feed bar where it is in contact with the nib.
Referring now to Figs. 3 and 4, identical grooves H in that part of the feed bar which is remote from the nib extend at right angles to the plane of symmetry, and transverse bores L, L which are so small as not to allow air to pass when filled with ink are provided for connecting the longitudinal grooves H, H with the ink-conducting capillary grooves E, E, as the grooves here do not extend into the immediate vicinity of the nib point. 1
When more ink is supplied to the nib than it can dispose of, the excess ink gradually rises toward the upper end of the grooves G or H. The upward flow of the ink is much furthered by the capillary action of the sharp angles K at the bottom of the respective grooves G and H the more so as these angles will always be kept moist on account of the depth and small width of the grooves. When the holder is held with the nib up the ink which is still in the grooves G or H flows back through the flaring inner end A of the barrel A into the narrow interstices J which are made by inserting the nib in the barrel with the feed bar, and through these interstices to the reservoir, not shown.
The grooves G and H may be made by any suitable tool, such as a side or slot milling.
cutter, and in this manner the manufacture is much simplified.
ll wish it to he understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a. person sk lled in the art.
in the claims aiiixed to this specification no selection of any particular modification of the invention is intended to the exclusion of other modifications thereof and the right to subsequently make claim to any modification not covered by these claims is expressly reserved. 4
