ill/4 7 UNITED STATES PATENT OFFER.-
RICI-IARD PERKINS, OF JOPLIN, MISSOURI.
FOUNTAIN-1 1111.
Specification of Letters Patent.
Patented Jan. 11, 1921.
Application filed January 19, 1920. Serial No. 352,382.
This invention relates to certain improvements in fountain pens and has relation more particularly to the feed bar therein and it is an object of the invention to provide a novel and improved feed bar provided with means whereby the flow of the writing fluid is sub stantially entirely stopped except during a writing operation.
It is also an object of the invention to provide a novel and improved feed bar for a fountain pen provided with means coacting with the nib or writing point, whereby the flow of the writing fluid'is under control of said nib or writing point.
An additional object of the invention 'is to provide a novel and improved feed bar for a fountain pen wherein the flow of the writing fluid is under control of the nib or writing point and wherein the amount or quantity of the fluid delivered to the nib or writing point may be regulated or varied by an endwise adjustment of the nib or point with respect to the feed bar.
The invention consists in the details of construction and in the combination and arrangement of the severalparts of my improved feed bar for fountain pens, whereby certain important advantages are. attained and the device rendered simpler, less ex-' pensive, and otherwise more convenient and advantageous for use, as will be hereinafter set forth, the novel features of my invention will be definitely claimed. I
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:
Figure 1 is a fragmentary sectional view illustrating a feed bar constructed in accordance with an embodiment of my invention and in applied position, the coacting nib or point being also in applied position.
Fig. 2 is a view in elevation of the working face of said feed bar; and
Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1.
As disclosed in the accompanying drawings, E denotes the delivery end portion of the barrel of a fountain pen and in which is inserted in a wellknown manner, an end portion of a feed bar F. In the present embod ment of my invention, the feed bar If is fr ctionally maintained in applied position within the delivery end of the barrel B, althoughit is to be understood that this feed bar F may be maintained in working position in any manner which fully meets with the requirements of practice.
The working face of the bar F is substantially convex in cross section and extending longitudinally of said working face along the inserted end portion thereof is a conduit 1, open at the inner end of the bar F and through which the writing fluid within the barrel B is adapted to freely flow during the writing operation. The inner end portion of the conduit 1 1S 1n communication with two conduits 2 diverging in a direction toward the writ-' ing end of the bar F, and the conduits 2 lead to and deliver in the pockets or depressions 3, preferably semi-spherical and which serve as traps to retard the flow of the writing the recesses or pockets 3 and operating for the same 'purposes.
, Leading from and in communication with the recesses or pockets 5 are the additional conduits 6 converging toward the outer end portion of the feed bar F and delivering to a single pocket or recess 7, also performing the same functions as each of the recesses or pockets 3 and 5 hereinbefore referred to.
The nib or point N is substantially concavo-convex in cross section with the radius of the concave face thereof substantially the same as the radius of the convex working face of the feed bar F so that, when the nib or fluid and also serve as reservoirs to hold a longitudinally of the bar F in carrying out my invention in point N is in applied or working position, the concave face of the feed bar F will have substantially close contactwith the working or convex face of the nib or point N with the inner end portion of the split a in the writing end of the nib or point N overlying the pocket or recess 7.
When the pen is not in use, the applied nib or point N serves to substantiallyseal the conduits 1, 2, 4: and 6 and the recesses or pockets'8, 5 and 7 so that flow of ink upon and along the nib or point N is effectually prevented. This is of decided advantage, particularly in the event that the pen should be inserted within a pocket or otherwise positioned with its writing end downwardly disposed.
During the writing operation the resultant fiexion of the writing end portion of the nib or pen end causes the same to move away and I separate from the working face of the feed bar F, whereby the requisite flow of the writing fluid to the writing end of the nib or point is permitted, but the quantity or amount of such flow is dependent upon the extent to which the inner end portion of the split a of the nib or point N overlies the pocket or recess 7. The more the inner end portion of the split a overlies the pocket 7, the greater the flow of the writing fluid, and vice versa.
From the foregoing description it is thought to be obvious that a feed bar for a fountain pen constructed in accordance with my invention is particularly well adapted for use by reason of the convenienceand facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible to some change and modification without departing from the principles and spirit thereof and for which reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown practice, except as hereinafter claimed.
The invention having been set forth, what I claim as new and useful is:
1. In combination with a feed bar pro-- vided with a delivering conduit leading to a pocket, a nib normally in contact with the bar and coacting with the pocket to prevent the flow from the pocket, the inner end portion' of the split of the nib overlying the pocket, said nib being adjustable with'respect to the bar and the pocket therein.
2. In combination with a feed bar provided with a delivering conduit leading to a pocket, said feed bar being free from outlets communicating with feed pocket, a nib normally in contact with the bar and coacting with the pocket to prevent the flow therefrom, the inner end portion of the split of the nib overlying the pocket, said nib being longitudinally adjustable with respect to the bar and to said pocket.
8. As a new article of manufacture a feed bar for a fountain pen including a. delivery conduit, additional conduits diverging from and in communication with said conduit, said bar having, pockets into which the second named conduits deliver, said feed bar being also provided with another pocket 1n communication with each of the second named pockets, said feed bar being free from outlets communicating with said last named RICHARD E. PERKINS.
