FEEDER FOH'FOUNTAIN PENS.
APPLICATION FILED MAR. 29, 1920- 1,359,918. I PatentedN0v.23,1920.
UNETED STATES TATENT ANTHONY o. RADER, or ALTA, Iowa.
FEEDER FOR FOUNTAIN-TEENS.
nesaeie.
To all whom it may concern:
.Be it known that T, AnrHoNY C. RADER, a citizen of the United States, residing at Alta, in the county of Buena Vista and State of Iowa, haveinvented a new and useful Feeder for F ountain-Pens, of which the following is a specification.
This invention relates to new and useful 1 improvements in fountain pens, and more particularly to one of the. self-filling type, adapted to permit filling thereof, without the use of the ordinary and well known rubber sack or buib as anink container, the invention comprehending an improved feeder or feeding device for the ink whereby the same may be caused to flow freely to the pen point or nib, but prevented from dropping or spilling therefrom and blotting the paper.
The invention comprises a divisional part of my application Serial No. $38,4 1:"), filed November 17, 1919, and an improvement thereon with respect to the feeding device therefor so as to prevent ink from exuding therefrom, to provide a pen which is absolutely leak-proof, simple and inexpensive of production and durable in use. 7
Heretofore all fountain pens in general, and so far as I am aware, and have investigated, as they empty and the air rushes in to' displace the ink, cause .a blot of ink to fall on the paper and especially the last drop, instead of being used up. The ink also tends to harden at the feeding device or passage, as well as between the pen point or near the end of the feed, thus preventing the proper and the free flow of ink, or entirely cutting off the flow.
It is also an object of theinvention to provide a device by which the greater portion of the back of the pen point is exposed at the concavedside, so as to facilitate the cleaning and in addition to'insure'uniformity of fiow of the ink at either side,-the construction being such to hold back the ink whereby ordinary jar or shaking of the pen and ink as in writing, will not cause the ink to fall off while the pen will always be provided with an even flow of ink when left for some time without using.
lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in application filed March the precise embodiment of the invention shown can be made without departin from the spirit of the invention. D
In the accompanying drawings: Figure 1 is a side elevation of my improved fountain pen showingthe feeding'device in longitudinal section at the pen point;
F 1g. 2 is a similar view showing the reversed side of the feed atthe back or con-' caved sides of the pen point nib; I
Fig. 3 is a detailed rearelev'ation of the feeder;
F 1g. 4: is a side View thereof; and V Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 4:-
Referring to the drawings indetail, in which like reference characters. designate corresponding parts throughout the several views; thenumeral 10 designates the cylindrlcalbarrel of the fountain pen, which is provided with the filling means described in connection with my prior application above referred to. The barrel is provided with the cap '11 at one end confining the Specification of Letters Patent. Patnted -N 1920 Original application filed November 17, 1919, Serial No. $38,4A5. Divided and'this 29, 1920. Serial No. 369,511.
filling means when the latter is'not in use, and at the opposite end' with a cap 12 which 1s designed to be engaged over the pen point 17 when the pen is'not'in use and over the cap 11 when the pen is in use, the cap .12 having internal threads spaced from the open end thereof engaging cooperating eX as indicated at 13, although it is to'be under stood that any other-form of connection or method of applying the cap 12 1nayjbe emternal threads on the end of the barrel 10 ployed ifdesired; The barrel 10 is inter;
nally threaded, preferably; to receive the ex ternal threadsof a plug 14:, as shown at 15,
the-plug being preferably beaded and apertured as shown at 16 to constitute a pen holder for the'point 17. i
The pen point or nib 17* aperture '16 in conjunction with "a feedi'ng dev1 ce18 preferably of semi-circular cross section and provided with a longitudinal groove or channel 19 extending to its upper is held in'the end for communication withthe interior of I the barrel whereby the ink flow-into said groove or channel. The opposite end of the groove or channel terminatesat a spaced distance from the pointed end 20 of the feeder, that is short of or within the anchor head 21 provided at the discharge end. The anchor head provides the opposed grooves or recesses 22 at either side of the reduced portion of the feed shank or feeder,
thus provided and againstwhich the. pen point 17 is fitted in order to be engaged in the'cylindrical opening 16 leading from the interior of thebarrel which is adapted for containing the writing fluid or ink. These recesses 22, provlde means for recelving excess or surplus ink, that might come out between the penand the feeding device.
It should also be noted that the shank portion of the feeder is very narrow, with comparison-to the width of the pen point at the 'concaved side or back. thereof, so as to ex-' proper feed, the formation of the shankor feeder being tapered above the narrow flat portion which 1s centrally disposed between the sides of the pen point or nib.
The shank portion is further, provided with a plurality. of transverse openlngs 23, preferably three'in number and located intermediately of theedge portions thereof at the front and back, in order that the'ink may flow through so as to secure even distribution or flow at either side and further preventing the inkforming and dropping off.
By the above construction, I am able to obviatethe inkdropping oil and blotting the paper, as it usually happens in fountain ensthat as the emot the air rushes in to cause a blot of ink to fall on the paper. VViththis device, the last dropof ink is'held by the anchor feed and is all used up instead of falling in a blot, the device pro viding more room on the pen point or at either side of the feeder for extra ink, while the anchor points and the recesses or grooves formed thereby, hold the ink back. This obviates the possibility of overflow resulting in the ink falling off and by reason of .making the shank portion of the feeder relatively narrow, it is very easy to clean out any ink that might dry in the sockets or recesses formed by the construction, when not used for some time and should there be more flow on one side than on the allow the ink to flow on the side at which there is less ink, thus insuring uniform feed and preventing the ink from dropping off. There is a certain, amount of adherence or cohesion between the ink through the openings at the opposite sides ,of the feeder, or shank thereof, which will prevent the ink from falling off and a uniform feed will always be insured even though left some timewithout using. As the device does not cover much of the pen point or nib, .it prevents theink fronrdrying up under it and stopping the flow.
Having thus described the invention what I claim is:
1. A feeder for fountain pens, comprising a cylindrical body merging into are duced shank terminating in a single arrowshaped head, the shank being approximately rectangular in cross section, and of uuequa transverse dimensions, the shank having a plurality of spaced openings extended ontirely therethrough and disposed in a line extending longitudinally of the shank, the
openings being spaced from both longitudt nal edges ofthe shank and the axes of the openings being disposed parallel to the minor transverse dimension of the shank.
2. A feeder for fountain pens, comprising a cylindrical .body merging into ,a reduced shank terminating in a single arrow shaped head, the shank having a curved edge prolonged to the top of the head and defining a point, the body and the shank having a superficial longitudinal duct extended upon the head and terminating in spaced relation to the point, the shank being approximately rectangular in cross section, and of unequal transverse dimensions, the shank having a plurality of spaced openings extended entirely therethrough, the openings being spaced from both longitudinal edges of the shank and the axes ofthe openings being disposed parallel ,to the minor transverse dimension of the shank.
In testimony that I claim the foregoing, as my own, I have hereto affixed my $1gD2t-' A. R. BRowNn, MARIE LARKINS.
