Patented July 13, 1948 UNITED STATES-Q PATENT, OFFICE FOUNTAIN PEN CAP HAVING A MULTIPLE CYLINDER, SINGLE AXIS CALENDAR Sophie Gonczi, Union City, N. J. Application July 29, 1944, Serial No. 547,140
f 1 Claim. 1 This invention relates to new and useful improvements in a, writing instrument and more particularly to a cap for a fountain pen having a multiple cylinder,-single axis calendar. More specifically, the present invention proposes the construction of a writing instrument having a built-in calendar capable of recording the day, month and year for many years.
A further object is to provide aninstrument as aforesaid in which the day, month and year fountain pen cap. I
Fig. 3 is an enlarged perspective view of a lock ring of the cap.
Fig.4 is an enlarged perspective view of the I barrel of the cap.
Fig. 5 is an enlarged perspective view of the year cylinder of the cap. a
Fig. 6 is an'enlarged perspective view of the month cylinder'of the cap.
Fig. .7 is an enlarged perspective view'of the outermost day cylinder'of the cap.
Fig. 8 is an enlarged perspective view of the intermediate day cylinder of the cap.
Fig. 9 is an enlarged. perspective view of the innermost day cylinder of the'cap.
The present invention is adapted for use with various types of writing instruments such as penc-ils andrpens. l For simplicity,.it is shown applied to the cap of a fountain pen but it will be 'understood that it can also be applied to the body 'of apencil' or pen.
The fountain pen, according to this invention,
comprises 'a pen part ID on which is secured a cap which functions like a'conventional fountain pen cap to coverthe pen-point when the penis not in use and is pushed on the end remote iromthe pen point when the'pen is in use.
Cap ll comprises a barrel |2 including a lower cylindrical portion-|3 having a window l4 for viewing thev days of the week as will presently appear.
threaded wall spaced from the portion I3 and numbers of cylinder 24 may be viewed. The outthis. open, and neck 22 extends therethrough.
has an intermediate cylindrical portion I5, of larger diameter than the portion l3, provided with a window It for viewing the months as will presently appear. larger upper cylindrical portion II in which is formed a window I8 for viewing the years as will presently appear, the number l9 being printed on the portion IT at one side of the window. The top of the barrel has external threads l9 and at the bottom of the barrel is an internal connected thereto.
In the barrel are disposed five thin cylinders fitting one within the other, each of the cylinders being rotatable and slidable relative to the other cylinders. The innermost cylinder 2| has a contfnuous uninterrupted cylindrical wall which at its upper portion has a neck 22 closed at its top .by a wall 23. On this cylinder 2| are longitudinal rows of numbers representing days of the week. Each row has seven day numbers, as is clearly shown in Fig. 9, each successive row starting with one day later than the row before.
The next cylinder 24 is similar to the cylinder 2| except that it is larger so that cylinder 2| fits inside of it with a sliding fit, and it is provided with a longitudinal window 25 through which the numbers of cylinder 2| may be viewed when the cylinders are properly adjusted for The top of the neck 26 of cylinder. 24 is The next cylinder 21 is similar to cylinder 24 but is larger so that cylinder 24 can fit within it,
with its neck extending through the open end of the neck 28 of cylinder 21.
Cylinder 21 is provided with awindow 29 through which the side diameter of cylinder 21 is slightly less than the inside diameter of portion H] of barrel I2 so that it can rotate therein.
A cylinder 30 is mounted on cylinder 21, neck 28 extending through the open neck 3| of cylinder 30. The names of themonths are printed on cylinder 30, this cylinder being disposed with its lower portion in the barrel portion l5.
A cylinder 32 is mounted on cylinder-30, neck 3| extending through the open' neck 33 of cylin- The lock ring. 34 is loosened and neck 33 1s The barrel |2 also has a still seized in a persons fingers and cylinder 32 is rotated thereby until the current year numbers show through window I8. The neck 3| is then seized and cylinder 30 rotated until the current month shows through the window I8, neck 33 being held stationary by the fingers of the other hand during rotation of the cylinder 30. The neck 28 is then seized and cylinder 21 rotated until the current row of day numbers shows through thewindow i4. Necks 3| and 33 are held stationary during rotation of cylinder 21.
If the current row of day numbers is not on cylinder 21, the window 29 is lined up with window l4 and neck 26 is seized and cylinder 24 rotated. If the current row of day numbers is not on cylinder 24, the window is lined up with windows 28 and I4 and neck is seized and cylinder 2| rotated until the current row of day numbers is visible. 3
The lock ring 34 is then rotated to screw it firmly on the barrel, the lock ring pressing downward on the portion of the cylinders surrounding their necks, thereby holding all of the cylinders in their proper adjusted position.
Each of the necks is serrated at its top to provide a finger hold. It will be noted by reference to Fig. 1 that the protruding necks make a very attractive top ornament for the fountain pen cap. It is contemplated that each of the cylinders willbe made of thin metal such as hard brass which slides easily and is strong. The construction of the cylinders having two cylindrical portions connected by an annular portion provides a very strong structure able to withstand much rotating.- While three day number cylinders have been shown, providing ample space for the numbers of rows of numbers needed to show the days of the month a week at a time, more or a less day number cylinders may be employed if desired.
The internally threaded wall 20 provides means for retaining the bottom of the day number cylinders and also for screwing on the part Hi. It is a feature of the present invention that the innermost day number cylinder provide the inside wall of the cap. The names and numbers may be printed on the cylinders in any desired manner, but they are preferably first etched A fountain pen cap comprising a cylindrical barrel having at its bottom, an inner short wall interiorly threaded, a lower cylindrical portion spaced from said short wall, a bottom wall connecting said walls, the upper .portion of saidbarrel being stepped twice providing an upper cylindrical portion and an intermediate cylindrical portion, the upper cylindrical portion of said barrel being exteriorly threaded, said upper cylindrical portion having a small window, said intermediate cylindrical portion having a small window, a longitudinal window in said lower cylindrical portion, the latter having the days of the week indicla thereon along one side of said longitudinal window and the first two numbers of the year indicla along one side of the window in said upper cylindrical portion, three interfltting cylinders disposed in said cylindrical barrel with their lower ends disposed on said bottom wall,
each of said cylinders having a neck'at its upper end, the innermost cylinder neck extending through and beyond the intermediate cylinder neck and, the intermediate cylinder neck extending through and beyond the outer cylinder neck, said outer cylinder neck extending above said barrel, said intermediate and outer cylinders each having a longitudinal window and said three cylinders having indicia of the days of the month,
two additional cylinders, one of said cylinders being disposed within said intermediate cylindrical portion and having a neck surrounding and shorter than said outer cylinder neck, months of the year indicla on the said one cylinder, the other of said cylinders being disposed within said upper cylindrical portion and having a neck surrounding and shorter than the neck of the first of said additional cylinders, the second two numbers of aseries of years indicla on said other cylinder, and a retaining ring surrounding said other cylinder neck and upper cylindrical portion and screwed on the exterior threads of said upper cylindrical portion for retaining all of the aforesaid parts of said cap together.
