OLAUS C. WOLD, OF CHICAGO, ILLINOIS.

FOUNTAIN-PEN.

Specification of Letters Patent.

Application filed May 16, 1911. Serial No. 627,449.

To all whom it may concern:

Be it known that I, OLAUS G. Wonn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain-Pens, of.

which the following is a specification.

This invention relates to a type of fountain pen having relatively wide nibs and, therefore, especially adapted for producing wide lines. It is well adapted, for example, to lettering operations in which the letters are to be shaded so that their vertical portions are broad while their horizontal portions are narrow.

In carrying out my present invention, I

i provide a pair of relatively broad nibs and a suitable mounting therefor, and a fountain mechanism for delivering ink from a well to a point between the nibs, so as to secure a proper flow of ink at all times.

I am familiar with a form of fountain pen similar to the general class above described, but the same is restricted to a form of mechanism in which the ink is delivered through a tube extending at right angles to the lower nib of the pen, and which tube passes through the upper nib. I have found that this construction is open to a number of serious objections; and, as will hereinafter appear, my present invention relates particularly to a type of construction in which the ink is delivered through a tube extending parallel to the nibs.

Objects of the present invention are, to provide a form of pen having the discharge tube from the well extending in a direction parallel to the nibs; to provide means for controlling the opening of the orifice of said tube independently of pressure on the nibs,

so that the flow of ink will always be under the control of the operator; to provide, nevertheless, a type of construction which may be adapted for use witha mechanism which will automatically control the flow of ink; to provide a construction of pen such that the nibs can be easily inserted or removed independently of any other mechanism, thus enabling me to use different widths of nibs in the same pen body; to provide a type of mechanism such as will insure a perfect and positive closing of the ink orifice; and in other ways and manners to generally improve the type of this class of pen.

Other objects and uses will appear from a detailed description of the invention, which consists in the features of construction and the combination of parts hereinafter described and claimed.

Referring to the drawings, Figure 1 shows a side view of the preferred form of pen, the rear portion of the handle being cut away; Fig. 2 shows an enlarged detail cross section of the front part of the pen of Fig. 1; Fig. 3 shows an enlarged detail elevation of the front part of the pen with the nibs deflected by pressure into working position; Fig. 4 shows a cross section taken on line 4:-4 of Fig. 3, looking in the direction of the arrows; Figs. 5, 6 and 7 show three sets of nibs, each of different width, but all adapted for use in the pen of Fig. 1; Fig. 8 is an enlarged detail side view of thefront part of a pen similar to that of-Fig. l, but provided with mechanism for automatically opening the ink orifice when the nibs are deflected by pressure; Fig. 9 is a plan View of the pen of Fig. 8; Fig. 1.0 is a view similar to Fig. 8, the nibs being deflected up into working position, however; and Fig. 11 is Patented NOV. 21, 1911.

a greatly enlarged detail of a modified form of finger operating mechanism.

As heretofore stated, I am familiar with a form of fountain pen, the ink delivery tube of which extends downwardly toward the lower nib, so that the orifice faces the same, and so that the mechanism for opening and closing the orifice must extend in a direction perpendicular to the nibs. Such a form of construction has a number of disadvantages, chief among which is that it is diflicult, if not impractical, to provide 'a mechanism for controlling the opening of said orifice at any and all times by hand. In the embodiment of my present invention,

I preferably use the handle of the pen itself as the ink well and carry the ink delivery tube straight out from the same to a point between the nibs. This being the case, considerably more space 'is available for' controlling the opening of said orifice than it While I have heretofore stated that in my present invention I provide an ink delivery tube parallel to the nibs, and not at right angles thereto, I do not intend to be limited to a construction in which the orifice itself is parallel to the nibs, but rather to a construction in which the tube from the ink well to said orifice extends parallel to the nibs and preferably between them.

Referring now particularly to Figs. 1, 2 and 3, the handle of the pen is designated by the numeral 17. It is hollow so that it may serve as an ink well 18; and into its forward portion 19 is threaded a cap member 20, shouldered at 21 to secure a tight joint against the handle. The rear portion 22 of this cap is counterbored to provide a conical opening which gradually tapers down to a tubular opening 23. The extreme forward end of the cap is extended out as an elongated delivery tube 24, the orifice 25 of the opening being counterbored so that it may be tightly closed by a needle. A sleeve 26 fits loosely over the delivery tube portion 24, its forward end 27 carrying a needle 28, which extends inwardly to close the orifice when the sleeve is drawn back into the position shown in Fig. 2. The lower portionof the sleeve is cut away at 29, directly underneath the needle, so that, when the sleeve is thrown forward, the ink may drop down to the lower nib 30 of the pen. A bell-crank 31 is pivoted to a lug 32 on the forward top portion of the cap, the horizontal arm of said bell-crank being suitably formed to provide a finger piece 33, which is nor-- mally thrown up by a spring 34. Two collars 35 and 36 are formed on the inner end of the sleeve, the vertical arm or finger 37 of the bell-crank engaging the space between said collars. Obviously, depression of the finger piece serves to throw the sleeve forward and open the ink orifice. The writing portion of the pen comprises upper and lower nibs 33 and 30 respectively. These are curved together in their rear portions 39 until they finally meet to form a pair of flat fingers 40, the two nibs being preferably soldered together in said finger portions. An elongated hole extends inwardly into the cap on each side of the sleeve to receive one of the fingers 40, whereby the nibs are held in position on the pen. The fingers may have such a snug fit in said holes that the nibs are held in position without the necessity of any additional mecha nism. It is evident that means should be provided for preventing the sleeve from rotating about the tube 24, as otherwise the hole 29 in the front end of the sleeve might eventually be turned so as to face upward. In the present instance, I so relate the nibs to the sleeve that the nibs perform this additional function of preventing rotation of the sleeve. To this end both of the nibs are cut away to provide an elongated slot 41, and the fingers straddle the sleeve. I then flatten the vertical portions 42 of the sleeve to such an extent that the same cannot rotate when once the fingers of the nibs have been properly inserted within the cap. This construction is well illustrated in Fig. 4. In order to remove the sleeve for replacement or repair, it is first necessary to pull out the nibs; after this the sleeve can be rotated through a quarter revolution and the arm 37 of the bell-crank may then be disengaged from the groove between the collars 35 and 36. Thereafter, the sleeve may he slipped off from the tube 24 endwise. When in use the nibs of the pen will be defiected over approximately into the position shown in Fig. 3, and the ink will be deposited on the lower nib, when it will run down into the angle 43 between the nibs. The operator, by depressing the finger piece 33 from time to time, can regulate the fiow of ink, thus placing the mechanism entirely under his control. As the ink runs out from the well, air must be allowed to enter the same and occupy the space thus vacated. To this end, a tip 44 is threaded into the rear end 45 of the handle, as illustrated in Fig. 1. A fine tube 46 projects downwardly from said tip and allows air to pass into the well through hole 47 in the tip. In use, it would not be customary to fill the well entirely full of ink. This being the case, the tube 46 would project upwardly beyond the surface of the ink, in case the pen were held with the nibs extending upwardly, so that the ink would not be spilled out through the tube and the hole 47.

In Figs. 8 to 10 inclusive, I illustrate a construction similar to that of Figs. 1, 2 and 3, in that the sleeve is stationary, the needle being movable, but in the present instance an auxiliary mechanism is provided for automatically controlling the flow of ink as the nibs are deflected by pressure. To this end a lever is pivoted to the lug 71 on the forward end of the cap, its outer arm being provided on its lower face with a pair of lugs 72 adapted to engage a collar 73 on the sleeve; so as to control both in and out movements of said collar. The outer arm of the lever extends outwardly to a point substantially over the center of the upper nib, at which point it carries a set screw 74. The latter may be so adjusted that as the nibs are deflected into the position shown in Fig. 10, the sleeve will be thrown out to allow a flow of ink. A leaf spring 75 tends to restore the sleeve to its normal closed position. In order to permit independent control of the ink flow, the lever may be provided with a finger piece 76, in which case its operation would be similar to that of the construction shown in Figs. 1,2 and 3.

In Fig. 11 is shown a construction substantially the same as that of Fig. 8, with the exception that the set screw arm of the lever is removed, thus making the operation entirely independent of the movement of the nibs.

Referring particularly to Figs. 2, and 11, it will be noted that the tip of the lower nib 30 extends out a slight distance beyond the tip of the upper nib 38. This being the case, when the nibs are deflected in service, as is well shown, particularly in Figs. 3 and 10, the upper nib will be forced out so that its tip comes practically in line with that of the lower nib. Reference also particularly to Fig. 9 will show that the tip of the upper nib is serrated, or provided with a number of slots, so that the tip is virtually severed into a number of fine fingers. It is found that such slotting of the tip of the upper nib insures a better and more even discharge of the ink than would otherwise be the case when the nibs are deflected in service.
