2 Claims.
' siderable amount of ink, permitting use of the contents o'fthepen over a considerable period of time.
A further object of the invention is to provide a fountain pen which is especially adapted for accurate printing v Other objects and'advantages of the invention will become apparent to'the reader of the following. description.
In th drawings:
Figure 1 represents a side elevational view of the pen.
Figure 2 is a vertical sectional view through the pen.
Figure 3 is a side elevational view of the pen with the adjustable tube removed.
Figure 4 is a fragmentary enlarged vertical sectional view through the lower portion of the pen.
Figure 5 is a side elevational view of the compression tube.
Figure 6 is an enlarged sectional view taken on the line 6-6 of Figure 2. J
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes an elongated barrel having a conically reduced end portion 6, termina i in an orifice I in which a ball 8 is adapted to seat. It is preferable that this ball be slightly engraved or roughened so as to carry ink. The lower portion of the barrel 5 has a filler plug 8.
A frusto-conical shaped cap I has a threaded portion H for threaded engagement, with the lower portion of the barrel 5, while the lower constricted portion of this cap I0 is inwardly disis a strip spring 13 having a finger engageable enlargement It at its upper end and a broad lower portion l on which is a cork or suitable packing element It. When the spring slide I3 is forced outwardly, the broad portion I5 will snap under the ball 8 and close the lower end of the cap l0, forcing the ball 8 upwardly and snug againstthe seat in the lower end of the conical end portion 8 of the barrel 5. I
As shown in Figure 3, the upper portion of the barrel 5 is threaded as at H to accommodate an internally threaded shell l8 which has a cap I9 secured to its upper end. The lower internal portion of the shell I8 is unthreaded as at 20 so that the same can be easily slipped over the upper end of the barrel 5.
A threaded stud 2| depends from the central portion of the cap I9 and over this is engaged the internally threaded upper end portion of a compression tube 22, 'which depends into the interior oi the'barrel 5.
Obviously, adjustment of the shell l8 on the threaded portion ll of the barrel 5 controls the compression of the ink within the barrel 5, to the end that the ink within the barrel is held under compression and against the ball 8 so that at all times the ball will be fully supplied with ink, to the end that when the same is rotated as when writing, ink will be carried ontothe surface to be written upon.
While the foregoing specification sets forth the invention in specific terms. it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention what is claimed as new is:
i. A fountain pen comprising a barrel provided with a writing ball at one end thereof, and compression means at the other end of the barrel for compressing ink within the barrel, and a cap for the ball, said cap being adapted to keep the ball properly seated within the corresponding end of the barrel, a slidable spring lement on the cap, a packingilemefitia'rried by the slidable element and adapted to snap against the ball end of the cap to cover said cap when the ball is not being used.
2. A fountain pen comprising a barrel, a writing ball at one end of the barrel, a cap on said end of the barrel having a ball-confining end, and a-slidable spring element on said cap constructed and arranged to snap over said ball-coni'ining end of the cap to cover the ball when not in use.
