Patented Dec. 24,n 1946 2,413,234 UNITED STATES»A PATENT, OFFICE 2,413,234 aE'rRAoTILE FOUNTAIN PEN Orvel M. Johnson, Little Rock, Ark. Application November 18, 1944, Serial No. 564,065 1 Claim. (Cl. 1Z0-49) 1 This invention relates to fountain pens and it consists in the constructions, arrangements and combinations herein described and claimed. More particularly, it is an object of the inven tion to provide a fountain pen wherein-the pen - to fit -flush with the opening I6; and upon the inner face of the cap a raised part 22 is formed of dimensions so as to engage within the opening I6. In order that the cap 2U may be held in releasable closed position, a leaf spring 23 is ñxed to the cap and extended rearwardly a distance whereit terminates Yin a recurved nib 24 which has bearing contact with the housing I0. As here shown, the spring 23 has a portion 23’ em proper is normally housed in a casing, but pro jectable to expose the pen point for writing pur poses, the pen proper including a catch means for holding the latter in exposed position, as well as including means for retracting the pen upon re 10 bedded in the body of the cap. The spring is outwardly bowed as may be seen in Figure 1, lease of the catch. exerting pressure upon the cap to maintain the It is also an object of the invention to provide latter in yieldable closed position. The spring a closure for the open end of the housing adapted to be moved to openposition upon projection of also functions as a pocket clip, as will be appre the pen proper without liability of contact with 15 -ciated. Within the housing I 0 a pen 25 is reciprocably the pen point. ` mounted, consisting of a cylindrical pen base 26 Additional objects, advantages and features of invention will be apparent from the following de upon the forward end of which there is mounted scription and accompanying drawing wherein a pen 2l. Upon the lower side of the base 26 a Figure 1 is a longitudinal sectional view of the ~ pen, in closed position. Figure 2' is an elevational View illustrating the pen in operative position. Figure 3 is a cross section on the line 3--3 of Figure 1. Figure 4 is a side elevation of the closure cap. longitudinally extended tongue 28 is formed, com plemental to a similarly extended groove 29 formed in the lower portion of the housing I6. The tongue and groove prevent rotation of the pen and insure a straight forward movement when the pen is to be projected. As may be seen in Figure 6, the tongue 28 extends beyond the forward end of the base 26 a distance so as to con Fig. 5 is a plan view thereof. tact the raised part 22 in advance of the pen Figure 6 is a side elevation of the base for point 2l. mounting of the pen. Figure 7 is a plan view of the pen removed 80 The base 26 is formed with an exteriorly from the housing. threaded part 39 and reduced terminal end 3|, receiving thereon a collapsible ink sack 32. A Figure 8 is an end elevation of the pen housing barrel, 33 is employed, having a closed rear end with the closure cap removed, taken on the line 8_8 of Figure 1. 34 and an interiorly threaded forward end 35 'I'here is illustrated a housing ID substantially 35 adapted to engage the threaded portion 30 of cylindrical for the major portion of its length, the the base, the barrel being of a length to readily rear end being open and exteriorly threaded as accommodate the sack 32 therewithin. The bar at II. A cylindrical -cap I2 is employed interiorly rel 33 is formed with an elongated opening 35 threaded and complemental to the threads il and within the barrel there is secured a ñat of the barrel. The cap I2 is formed with an end 40 spring 3l which is disposed before the opening opening I3' deñned by an inwardly turned flange I4. The forward end of the housing I 0 at the upper side is downwardly curved as at I 5, a slight so that it may be readily flexed for the purpose of compressing the ink sack, as will be required in filling the pen. A collar 38 is fixed upon the barrel 33 by distance, the opening I6 being defined by form ing the walls of the housing at a rearward in 45 means of a rivet 39 which also secures catch clination, as indicated at I'I. The underside of device 40. The collar 38 'is so located upon the the housing IIJ at the opening I6 is formed with barrel that when the pen 25 is in retracted posi a flat portion I8, extending longitudinally of tion the collar will abut the flange I4 of the housing. the housing a short distance, and upon each side of said portion, ears i3 are formed, as may be 50 A helical spring 4I is mounted upon the bar clearly seen in Figure 8. The ears are of elon rel 33 one end having bearing engagement with gated form, merging rearwardly into the wall of the collar 33 while the other end engages the the housing III. A closure cap 20 is mounted terminal rear end of the housing I3. The spring swingably between the ears I9 upon a pintle ZI, urges the pen to its retracted position as may the over-all dimensions thereof being such as 55 be seen in Figure 1. 2,413,234 '4 The catch device 40 is a ilat spring element, will thus be held in operative position for writ the rear end of which is formed with a» notch ing. When it is desired to retract the pen, the ’52 adapted to engage beneath the iiange I4`when the pen is moved to operative position. In order to permit the necessary flexing movement of catch 40 is depressed to release the ñange, when the spring 4I functions to retract the pen into the housing, and at the same time, the spring the spring, a recess or opening 42 is formed in the barrel 33 which Will permit the catch to 23 urges closure 20 to closed position. While I have shown and described the inven spring downwardly thereinto. tion speciñcally, this is by way of illustration only, and I consider as my own all such modi When it is desired to ñll the pen, the cap l2 is removed and the pen may then be drawn 10 ñcations in construction as fairly fall within rearwardly from the housing. The point 21 of the scope of the appended claim. I claim: the pen is deposited in an ink well or the like, A fountain pen comprising a housing having and the sack 32 compressed by exerting pres-r an open end, a pair of ears on the housing at sure on the spring 31. Upon release of the one side of the open end, a closure cap hingedly spring, the sack will expand and ink will- be drawn into the sack. The pen is now- replaced mounted between the ears, a pen within the housing having an end projected through the in the housing, care being taken to see that the i tongue 28 engages within the groove 29. The open end of the housing, spring means within cap l2 is then engaged upon the housing.` When the’l housing operativelyengaged between the pen it is desired to use the pen, inward pressure is 20 and the housing, for ‘holding the pen within exerted upon the end 34 of the pen, causing the the housing, said closure cap >having a raised latter to move longitudinally of the barrel, pre interior face, a tongue on said pen for engaging senting the forward end of the tongue 28 against the raised'face of the closure cap in advance of the raised part 22 of the closure cap. It‘will be the point of said pen upon outward sliding move noted that the tongue 28 engages the part 22 25 ment of said pen, and a leaf spring having one in advance of the pen point 2l', so that damage to the latter is avoided. 'I'he'closure 20 will be swung to open position with the pen point ex end mounted in said closure cap for holding the closure cap releasable over the open end, the other end of the spring being recurved and nor posed. In this position'the catch 40 will have become engaged with the ñange I4 and the pen mally contacting the housing. ORVEL M. JOHNSON.
