-Thisinvention is concernedwith relieving the `armoyance attendantV upon having Lafonn- ,7p tain pen Vsuddenly run dry yat a (,ritlcal moment'. ltr-is a matterof frequent occur- Irencetofhave the supply of ink suddenly, give out while in the midst of vasignaturaorhsome eher andre-wars important Writingi i To say thelleastythisis an inconvenience. The writer ,is thereby required i to ,reach for theinkbottleand refill his pe`n. This not enly'means the llossof some timeabut Vit is easily conceivable person concerned might be embarrassed.
i The 3 remedy herein proposed y is to provide thebarrel 1 of a fountain penwith 'a dual reservoir 'orinlrsac 2 of rubber or other appropriate-liexible material whichis divided Q5 into mainandauxiliary ,reservoirs 3` and 4 by means of a` constriction 15, the 'making of whichis the subject of .an ingeniousprocess. `This inlrsac is adapted to be acted upon by a compressor mechanism generally denoted,
and'it is in tli's that a large part of the novelty l resides, 1 f @y [slot or otherr'openinglocated somewhere near .the .closed end V8` of-f-thebarrel l has'iixedly vcombined therewith .f (Fig. 5) `.and A945 located'mediall-y thereof Ava pin 9. actua@ ing lever 1Q lis pivotally andslidablykmount.- -ed on the pin for which purposerthe-lever has a slot kl1v for the. reception of the. pin.V v
The ilever.. 1i0 is in" the nature of :ai solid har 415m that in soinerinstanceslthe 8 0 or inner edge'of th (Fig. 5) but might be struck up from sheet metal bent to the proper proportions. Its ends 12, 13 are reduced by shaping away the material on the nether or inner edge until the extremities are approximately as thick as the pen barrel (Fig. 2). These shaped places provide recesses in which the protrusions 14, 15 ofl a lever .supporting spring 16 bear to maintain the lever in its proper resting position (Fig. 2) when the dual reservoir 2 is fully distended. 'i
It is not necessary for the protrusions' 14, 15 to lit the recesses adjacent to the ends 12, 13 exactly. They need only to bear against the ends of the lever 10 thus keeping the latter level in its slot 7. Either end of the lever may be depressed in the slot 7 Vby the thumb nail, depending on whether vit is desired to compressrboth reservoirs 3, 4'prior to lling (Fig. 3), or only the auxiliary reservoir 4 (Fig. 4) in order to discharge the contents into the main reservoir 3. The lever 10 thus becomes the selecting means by which either all or only one of the reservoirs is compressed. These actions involve the use of a lug 17 on the yexposed edge of the lever 10, which is adapted to be engaged by the thumb nail to slide the4 lever 10 in one or the other direction preparatory to exercising the required pressure on the inlr sac.
It is observed vthat the protrusions 14, 15 are bent into format the ends of a slot 18 in the spring 16. The spring is slit and parts of the metal are bent up into the shape of protrusions. The ends 12, 13 of the lever l0 work in the slot either for the simultaneous compression of the two reservoirs 3, 4 (Fig. 3) or the compression of only the reservoir 4 (Fig. 4). Y
That end of the spring 16 adjacent to the slot 18 has an arm 19 which carri-es a circular yoke 20 (Fig. 6) which lits the pen barrel thus to establish an adequate support not only Vfor the spring 16 but the entire inner component of the compressor mechanism 6. This inner' component consists of the spring 16, already mentioned,faJ main presser strip 21 and an auxiliary presser strip 22. The purpose of the strip 21 is to compress the main reservoir 3, while the purpose of the strip 22 isto compress the auxiliary reservoir 4.
The main presser strip 21 is riveted or otherwise secured at one end to the spring 16 as at 23. The other end has a bifurcation 24 (Fig. 7 )l to the insides of which ears 25 (Fig. V8) of the auxiliary presser strip 22 are pivoted, the approximate extent of pivotalmotion of one strip to the other is shown in Figure 4. A transverse groove 26 stamped in or struck across the main presser strip 21 prior to .furcating the adjacent end permits of easier manufacture of the presser strip, especially as it may be desired to have the upper e strip made slightly higher than the Vflat portion yin the immediate re ion of a slot 27 in the presser strip. The ends 12, 13 of the lever 10 pass into this slot during the Working of the lever 10 as seen in Figures 3 and 4.
One end of the auxiliary presser strip 22 is bent up at 29 to provide a rest which bears against the under side of the lever supporting spring 16 (Fig. 2) and tends to relieve the auxiliary reservoir 4 of the weight and pressure. This rest is part of a reduced end V30 of the auxiliary strip 22 (Fig. 8) which is adapted to swing between the furcations 24 to a slight extent (Fig. 4). The opposite end of the strip22 is forked at 31 (Fig. 8), and at the inner end of the forl there is a stop 32 with the opposite sides of which the lever ends 12, 13 are adapted to engage (Figs. 3 and 4) to limit the swinging or raising movement of the lever 10.
A depression 28 stamped from the material of the strip 21 at one end ofthe slot 27 extends into the'forl; 31 under the circumstances in Figures 2 and 3. The end of this depression clears the adjacent stop32 of the strip 22; The purpose of this depression is to enable theuse 0f a shorter lever stop 32 thanv wouldotherwise be possible. Another effect of this depression is a greater capacity of reservoirs 3, 4.
This is easily understood. The lever 10 i must clear the stop 32 while in its resting position (Fig. 2), but when the lever 10 is swung in one or the other direction (Figs. 3 and 4) its ends 12, 13 must engage one or the other side of the stop. If the strip 21 were left perfectly straight up to the point of the stop 32 it follows that the latter would have to be longer in order to be in a position where the ends 12, 13 can engage it. By depressing the `strip at 28 the stop 32 is in effect reduced to a lower location, enabling the spring 16 to move the main presser strip 21 farther out toward the lever 10 (Fig. 2) and thus making possible a greater capacity of the ink reservoirs 3, 4.
Thus far the operation of the compressor mechanism isreadily understood. Consider the position in Figure 2 and assume that it is desired to refill the ink sac 2. The thumb nail of the right hand is placed edge-on against the lever 10 at a point near the end 12 and pressedin. This raises the end 13 above the surface of the barrel 1. The-thumb nail is then slid along the lever 10 until it comes in contact `with the lug 17, whereupon a continued push will slide the lever over the pin Qbyvirtue of the slot 11 until the pin occupies the front end of the slot.'
t is now an easy matter to raise the end 12 with the fore finger of theright hand, using the pin 9 asa pivot, until the position in Figure 3 is assumed. Y The lever end 12 rides against the Vmain presser strip 21, and Vsince the auxiliary strip 22 cannot move by virtue of bearing against the bridge portion 33 between the bifurcation 24 and slot 27, the result is a simultaneous depression of both reservoirs 3, 4 (Fig. 3). The pen point 34 (Fig. 1) is now dipped into the ink, and upon a motion of the lever` to its original position, by which a release of the dual reservoir 2 is effected, ink will be drawn in.
Upon desiring to transfer the contents ofl the auxiliary reservoir 4 into the main reservoir 3 the foregoing operation of the lever 10 is reversed. The end 13 is now first pressed in so that the lever can be slid until the pin 9 occupies the other end of the slot 11, whereupon the lever is turned (Fig. 4) so that the end 13 rides against the auxiliary presser strip 22 and turns that independently of the main strip 21. Pressure is applied to the reservoir 4 only with the result that the ink is emptied into the main reservoir 3.
The construction of the ink sac is an important factor of the invention. It has been found that the making of the constriction 5 by molding is virtually impossible, or at best so difficult as to make the cost prohibitive. The alternate choice is to take a tubular ink sac and vulcanize it together at a designated spot so as to produce the constriction. This has the disadvantage of spreading or flaring the sides of the sac so that insertion into the barrel 1 becomes diilic'ult.
The remedy consists of initially moldingl the sac 2 with a slight constriction 35 (Fig. 10). This is easily accomplished; The constriction 35 is then pressed down and acted upon by an appropriate vulcanizing instrun ment so that a vulcanized spot 36 (Fig. 11) is produced. rI`he attendant spreading of the constriction 35 is kept within the bounds of the cylindrical sac 2A (Fig. 11) so that there will be no difficulty whatever in inserting the sac in the barrel 1.
The vulcanizing is done in such a manner that one or more ducts 37 (Figs. 5 and 12) are produced. It is through these that the ink ink iows from tnc reservoir to the other. rIhe vulcanized spot 36 (Fig. 11) is to be identified as the constriction 5 (Fig. 2), and according to the position of the compressor mechanism 6 it will be seen that the latter can be worked without in any way interfering with the constriction 5 or, more especially, with the ducts 37.
It is obvious that a numberof possible variations of the fundamental idea may be carried out in practice. For instance, instead of producing the ink duct or ducts 37 by vulcanization it is possible to use a metal clip to hold the two walls of the sac together, forming either one or two ducts as desired. Or, instead of vulcanizing the walls together, Jhey might be cemented tovequally good efect.
The important thing is to form the ink channels or ducts 37 by holding the opposite walls of the sac together in such a way as to form one or more connectingchannels between the mam and auxiliary reservoirs.
Each duct must be of suiiciently small cross sectionsothatthe surface tension of the. ink will'be great enough` to prevent its flowing out of the auxiliary reservoir until forced out byLthe presser strip; y f
