FOUNTAIN PEN.
Application filed April 25, 1925. Serial Ne. 25,854.
My invention relates to fountain pens wherein it is desired to provide a particular means for operating the same so that it can be filled easily and quickly without any complicated mechanism.
My fountain pen is designed to use an ink sack made of rubber or other suitable flexible material, which sack is large enough so as to practically fill the barrel for concealthe sack. The barrel may be made of tubing having a thin wall or of any other suitable material, and for convenience applicant has illustrated the barrel made of tubing such as precious metal or other suitable metal tubing, which gives the finished pen a barrel of ordinary size, yet providing a very large ink sack which practically fills the inside of the barrel.
A feature of the invention resides in a filling means which is adapted to extend or r the sack to be detachably secured to the pen'asse-mbly in a manner so that it can be taken apart and the ink sack can be renewed when it is desired. This filling means in cludes a pressure bar connected in a manner to freely move horizontally when engaged by the fingers and a bearing bar rigidly positioned and connected with the pen assembly in a manner to be detached therefrom when desired. The bearing bar is adapted to extend beyond the ink sack and is provided with an opening which engages with an operating tongue to lock one end of the pres sure bar slidably connected to the outer end of the bearing bar and freely removable therefrom when it is desired to disassemble the parts. The simplicity of construction of my fountain pen is apparent and of an important nature. The sack compressing .means of my pen provides a covering adaptedto hold the sack in alignment with the bearing bar and sufficiently cover the sack so that it-can be readily inserted into the barrel after it has been filled.
Afeature of the invention resides in means including only two parts, simple in design, which can be stamped out by suitable dies from sheet material and which are so formed so as to be connected together in a manner to operate to compress the ink sack between theparts and thus practically fill the sack with ink. Ordinarly in fountain pensusing a sack for the ink. either a very small sack is used because of the mechanism for operating to depress the same or only portion of the sack is collapsed and thereby preventa large amount of ink entering into the sack wh n it is filled. I overcome these features by completely collapsing the sack between the bearing bar and the pressure bar which are held together as an operable unit in the assembled pen construction, yet are separable in a manner so as to facilitate easy assembly or replacement, or taking apart when it is desired toplace a new sack on the pen assembly.-
The invention includes other features which will be more clearly set forth in the specification and claims.

l igure-v 7 illustrates the bearing bar removed.
Figure 8 illustrates the ink sack.
Figure 9 illustrates the pen assembly and filling unit as it would appear in operation in compressing the sack so that it can be filled with ink.
Tn the drawings the pen A is of ordinary outer appearance, having a barrel 10 and a cap 11 which carries the clip 12. The cap is removable in the ordinary manner from the barrel 10. i
The barrel 10 is threaded at 13 which threads are adapted to engage with complemental threads in the cap 11 as illustrated'in the drawings.
The pen assembly B is provided with a pen 14 which fits into the connector 15 in the ordinary manner and which is provided with. a nipple 16 for receiviug the neck 17 the sack 18. The sack 18, is adaptedto be sealed onto thenipple 16 in a suitable manner so to form a tight nipple between the pen assembly and the sack 18. The shoulder 19 of, a cylindrical shape is adapted to receive the spring gripping aws 20 of the l 53' bar 21.
Tn. bearing bar 21 is formed with a longitudinally extending hollow shaped bearing bar aortion 22 which forms a lon itudinal l e recess into which the body of the ink sack 18 extends andthus permitting the bearing bar 21 to fit about the ink sack closely. The
spring gripping jaws frictionally engage the shoulder 19 in a manner so that the bearing bar can be easily removed when desired.
The pen A is provided with a pressure bar 23 which is formed with a longitudinally extending portion having a stiffening rib 24 formed therein to provide rigid construction and to stiffen the same. The bearing bar21 is also provided with a longitudinally extending rib 25 which is adapted to stiffen and strengthen the bar so that it will extend approximately parallel in operation with the ink sack 18 and to provide the necessary rigidity to this member;
The pressure bar 23 isformed with engaging cars 26 which are adapted to fit around the neck of the sack 18 at a point spaced slightly away from the nipple 16 and these ears are adapted to engage in the recess 27 formed in the bearing bar 21,
thus permitting the ends of the ears 26 to lie, as'it were, countersunk into the bearing bar 21; The outer end of the pressure bar 23 'is formed with a tongue .28 which is adapted to extend through the slot 29 and is provided with a shoulder end 30 formed by bending the end of the tongue at approximately right angles to the tongue 28. The
In operationthe pen unit 13 is removed with the operatingmeans byv unscrewing the barrel '10 from the connector 15 which is threaded at 32 which engages with the threads 13 on the barrel. Then unit B with the operatingmeans forthe sack 18 is held inthe hand, as illustrated in Figure 9, and
bythe fingers the pressure bar 23 is pressed against the sack 18 and the sack is collapsed on the bearing bar 21. The ears 26 and the shoulder 30 are moved out of engagement with the back of the bar 21, as illustrated in Figure 9, permitting the pressure bar to freely operate and to form a flat longitudinally Xtending stifl bar means for fully collapsing the sack for practically the entire length of the same. his permits the sack to be so completely collapsed and readily operated that the pen may be filled with a large amount of ink. V
This form of construction of fountain pen provides a means for filling the same, making it necessary for the user to take the barrel 10 off of t 1e sack, thus permitting the user to inspect the sack to readily see that it is ingood order, perfectly resilient, and notdried out or cracked, so that it will perfectly receive the ink. The biggest detrimental features of fountain pens occur from these ver conditions orevailins' in a fountain pen without the operator knowing it and thus the ink is not drawn into the sack, or the sack is not in good live condition so as to receive the ink, and thus the pen is accused of not operating perfectly. My invention' overcomes these features, permitting the operator to readily see at glance the condition of the sack and to know that the pen is not in good order, or is in need of parts. a
It is quite imprtant to consider in my fountain pen that the operating parts of my pen are simple, inexpensive,.to manufacture, formed of thin sheet material so as to take only a small amount of space in the barrel, and adapted tooperate perfectly in such asimple manner that anyone can readily comprehend the operation.
lot!
In accordance with the patent statutes I V have described the principles of operation of my fountain pen and while I have illustrated in the drawing a particular formation of the parts, I desire to have it understood that these are only illustrative, and that the invention can be carried out and applied to uses other than those above set forth and I within the scope of the following claims.
