AsHMoRE FOUNTAIN PEN l Filed Dec. 24, 1931 @gmx Patented July 18, 1933 UNITED STATES PATENT oFFicE LEON HEEL ASHMORE, OF COLLINGSWOOD, NEW JERSEY, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO THE ESTERBROOK STEEL PEN MANUFACTURING CO., 0F CAMDEN, NEW JERSEY, A CORPORATION 0F NEW JERSEY FOUNTAIN PEN Application led December 24, 1931.
My invention relates to fountainpens and one object of such invention is to provlde means for renewing the pen nibs or points atvslight expense, in order that nibs or points of the ordinary or usual type, such as those made of steel and /or the less expensive metals, may be readily and successfully employed instead of the more expensive gold nibs or points usually employed with fountain pens.
A further object of my invention is to provide simple and efficient means for replacing pen nibs or points in a fountain pen without damage to the latter or the nib or of displacement of the nib or point with respect to the feeder member and without soiling the hands.
A further object ofmy invention is to provide a carrier or support for a pen nib or point and the feederfinember employed therewith, which parts are associated in relatively fixed relationship as a unit for detachable connection with a pen barrel or a member carried thereby; such unit element being replaceable by a similar unit element (or elements) carrying a pen nib or point When it is desired to renew the latter.
A further object of my invention is to provide a unit 'carrier for the pen nib and feeder member that will be disposed wholly within and substantially concealed by the fountain pen barrel or a pen section carried thereby.
And a still further object of my invention is to provide a novel unit structure that will be sealed ink-tight when assembled with a fountain pen.
These and other features of my invention are more fully described hereinafter; reference being had to the accompanying drawing, in which:
Figure 1 is a longitudinal sectional View illustrating sufficient of a fountain pen structure of a type to which the unit pen nib or point supporting structure forming the subject cf my invention may be applied.
ig. 2 is a view illustrating the parts of the replaceable unit comprising the pen nib or point; the feeder member, and the carrier or holding element therefor, shown in Fig. 1, in separated condition.

Figs. 5 and 6 are detached views illustrating on a larger scale modified forms of unit carriers Within the scope of my invention.
The usual fountain pen, in almost universal use, is one provided with a gold nib or point having a substantially fixed and properly adjusted position at the end of the pen barrel and associated with a feeder of suitable character. It has been proposed and fountain pens have been developed which employ as nibs or points the ordinary steel or. similar pens of commerce, which,hitherto,
have not usually been employed as the nibs or points of fountain pens.
In the use of these nibs or points made of metal other than gold or its alloys, it is necessary to renew-them at intervals, depending upon the wear. As ordinarily constructed, it is a rather messy operation to change the nibs or points of fountain pens with the additional difculty that as the nib or point and feeder are independent members and should have a certain definite adjustment or relation with the feeder member for proper use of the pen, itis somewhat difficult to insure the desired relation when inserting the separate nib or point and feeder member in the tubular cap or pen section at the end of the pen barrel which, in many of the present types of fountain pens, carries a rubber inkcontaining bag. With a view of overcoming these diiiiculties in the use of fountain pens which require renewal of their lnibs or points at intervals, depending upon wear of the same, it has been proposed to employ a unit carrier for the nib or point and feeder member whereby a new nib or point may easily and quickly replace an old nib or point.
My invention comprises a unit element i n n consisting of a carrler or support which may.
and positioned with respect to the feeder member, to insure proper cooperation of such parts in order that they may perform the duty for which they are intended. My invention further includes a carrier constructed to provide an ink-tight joint between the same and the element of the fountain pen structure in which it is mounted.
In the drawing: represents the usual barrel ofa fountain pen, shown in the present instance as receiving a pen section B; the latter carrying the usual ink bag C, commonly employed with many modern fountain pens. In the usual practice, the pen section B receives the pen nib or point and the feeder member associated therewith; such feeder member and pen nib tting the bore of the tubular cap very snugly and the feeder member confining the shank of the pen nib or oint between its surface and the wall of said ore. yIn lieu of such arrangement, I have provided a detachable carrier for the nib or point and the feeder member which carrier, with the nib or point and feeder member disposed therein in a fixed or substantially fixed position or relationship, is insertible and removable as a unitary whole With respect to said barre One form of my improved unit carrier is shown in the position of use in Fig. 1, and may comprise a support in the form of a thimble or cup l, with a nib or point 2 and a feeder member 3 inserted therein. The feeder member may be of any suitable type and occupies the space between the pen nib or point and the annular wall of the thimble formin the c rrier; such parts being in tight and re atively fixed engagement therewith.4
The three elements are maintained in exact coordination; the pen nib or point and the feeder member being positioned longitudinal 1y by engagement with the end wall la of the thimble or cup 1, and together comprise an insertible unit that may be sold with and for application to fountain pens of a construction adapted to receive the same.
The thimble or cup of my improved unit element is externally threaded at 4, preferably at its outer end for engagement with an internally threaded portion b at the end or adjacent to the end of the pen section B, or the end of the pen barrel. The rear wall la of the carrier is apertured at lb and the feeder member may have its ink groove 3a slightly enlarged by a diagonal or other cut at its rear end, as indicated at 3b for communication with such aperture. My improved unit carrier is wholly contained within the pen section B and is substantially concealed by theJ same. At the same time it may be readily separated from the rest of the pen structure for application of a fresh carrier with nib and feeder in proper association therewith. The pen nib and feeder mempen section B, or the end of the penfeeder member serving as gripping means for such turning action. While the thimble or cup when removed may be fitted with a new nib, the structure is so inexpensive as to permit discarding of a unit element when the pen nib or point wears out or becomes impaired in use.
The inner end of the thimble or cup comprising the inserted unit carrier may be beveled as indicated at 5, for engagement with a beveled shoulder b formed Within the pen section B; close engagement of such beveled surfaces insuring that an ink-tight and leakproof joint will be formed at this point.
In the modified types of shells or cups forming unit carriers and illustrated in Figs. 5 and 6, the seats are disposed at different points with respect to such shell. In the form shown in Fig. 5, the shoulder b comprising the seat is directly adjacent the threaded portions of the elements. In Fig. 6 the shoulder to form the seat b is disposed at a point intermediate the rear end of the shell and the threaded portion thereof. In each instance these seats are beveled complementally to a beveled shoulder portion on the shell to insure tight, leak-proof joints when a unit carrier is finally seated' in place. By preference there is a slight clearance between the wall of the inserted shell or thimble and the bore of the tubular part carrying the same, independently of the sealing joint or seat, in all forms of my improved structure. Such clearance is clearly indicated in Figs. 5 and 6.
As may be readily understood, several of these improved unit nib or point carriers may be sold with a fountain pen of a construction designed to receive the same as articles of merchandise; similar carriers, with any desired forni of pen nib or point, being also sold independently of a fountain pen for application thereto, so as to provide replacements for the original unit structure.
Vhile fountain pens of the type having collapsible ink bags which may be filled automatically upon retraction of collapsing means have been illustrated, my invention is not limited thereto and other forms of fountain pens, among which may be mentioned those filled by suction by the action of a piston member, may be equipped with the unit nib or point and feeder-carrying member forming the subject of my invention.
It is, of course, within the scope of my invention to employ gold nibs or points in connection with the form of unit carrier which I have devised, and the claims are intended to cover unit carrier members for connection with the barrel of fountain pens containing ink supplying means, Whethersuch nibs or points are of steel or of any other metal. In like manner, the feeder element may be of any type that will properly perform its function. It may be-entirely different from the form of feeder disclosed, which representation is more or less diagrammatic and is intended .to indicate means for performing a function rather than the member that will be actually employed for such purpose.
While the shellor thimble forming the carrier of my improved unit structure may be made of various materials, I prefer to make it of a non-corrodible metal.
Various modifications may be made in connection with this structure without departing from the spirit and scope of my invention as set forth in the appended claims.
