To @ZZ whom it may concern:

Bev it known that l, Hanni: Brook, a citizen ot the Unitedl States, residing at tialveston, in the State of Zlfexaafhave invented certain new and usei'ful bnprovements in ,Writing Pens, oi' which the following vis a tull, clearand concisedescrilition.

My invention relates to writing pens, my more particular V purpose being to provide a pen point oi simple construction and easily and cheaply made of stock material easily obtained, the pen point having advantages or" strength, durability and elegance, and being capable of holding a considerable quantity 0.1": ink aswell as of conserving the supply or charge of ink it is holding` while in actual use in writing. Y

My invention further contemplates a pen point oi such 'form as to prevent the mark made by the point from unduly spreading; or in other words, to prevent the pen point frommaking too wide a mark, in the event that a little too much pressure is applied to it in writing.

The main purpose ot my improved pen, however, is to enable it to be used in making carbon copies. lt is admirable for making out carbon bills, which would ordinarily be made out by the use oi' pencils, hard enough to impress the carbon sheet or sheets through the top sheet.

Reference is made to the accompanying drawing forming a part of this specification, and in which like characters ot reference indicate like parts throughout all ot the figures.

Figure l is a perspective, showing' my improved pen point as mounted in a suitable pen staff and in actual use in writing.

Figure 2 is a view, partly in side elevation and partly in section, oit the device shown inV Figure l.

Figure 3 is a section on the line 3-3 of Figure 2, looking in the direction indicated byi the arrows.

A pen staff t, made orl a single integral piece of wood or other suitable material, is provided kwith a round hole 5 disposed axially in relation to the pen staff.

Extending into the hole 5 is a cylindrical member 6 made of metal, preferably brass, aluminum or steel. It may be plated with nickel or silver it desired. The cylindrical member 6 is provided with a cylindrical hole 7 extending axially into it, for a distance extending approximately one-halt of its K iSpeoi'fication of Letters Patent. Patented Feb. 14, '1922.

i921. Serial No. 469,815.

The cylindrical member G-is further provided with a portion `8, integral with it and having the proximate form of a cone. The

conical portion 8 is; provided with a tip 9,

integral/ with it, but bent at an angle of about thirty degrees relatively to the general longitudinal axis of the cylindrical member y 6. The conical portion 8 is provided with passages llof the form shown, each passage ll tapering in width and also indepth toward its ends, and provided with a shallow and narrow portion 12 extending to the point l0, with which the tip l() is provided.

The tip 10 is quite small, but is not so sharp as to be liable to catch into the paper when used for writing. It is just blunt enough to glide smoothly over the writing paper.

The parts are so proportioned and arranged -that when the pen stad, carrying the pen point, is brought into the position it would occupy when held in a position suitable lor writing, the tip lO resting upon a sheet of writing paper, as indicated in Figure l', the axis of the tip is approximately vertical. This vertical position for thetip is by far the best it can assume for the purpose of delivering the ink uniformly in writing, because with the tip in a vertical pos1tion-that is, the axis of the tip being perpendicular to the plane of the writing paper-all sides of the tip are equally symf metrical in relation to the general verticalk axis of the tip. Yet, owing to the factthat the portion 9 is bent relatively to the general axis of the pen statt, the pen staii:` as a unit may be held in the position it naturally assumes as held by the average personln writing.

The construction above described presents quite a number of advantages. The passages 11 hold each a relatively large quantity of ink, and the fact that the portion 9 is Vbent relatively to the general axis of the pen point causes the ink to flow through the bent passages. Thus as may be understood from Figure l, gravity acts alittle more directly in causing` the ink to low downwardly after it reaches the portion 9 than before it reaches such portion. The res-ult is, that the charge of ink carried by the portion 8 is so supported that it does not run ofi too easily, and yet such small portion of the charge of ink as may at any particular moment be carried upon the portion 9 can flow with suieient lfreedom for purposes 4having :sutlicient firmness to properly im of Writing. The net result is that a. given charge oi' inl; carried by the pen point lasts a `long time, and enables considerable Writing` to be done With a single dipping ofthe pen in ink, and yet owing to the form of my pen it cany carry an .unusually large charge oi' ink at each dipping.

The principal advantage of my pen, however, is that it enables one or more carbon copiesvto Vbe readily made, the pen point press the `carbon sheet, through the top sheet. In this relation,` the device is Well adapted for making' out bills, and'is much better for this purpose than the pencil customarily employed.

I do not limit myself to the precise con- #struction shown, as variations may be made therefrom Without departing `from my 1n vention, the scope of which is commensurate withy my claim.

I claim- As an article `of manufacture, a pen point having the general proximate form of a cone and provided with a small portion having also the general proximate form of a cone the axis of which extends at an angle from the axis of the first-mentioned cone, so as to'interpose a bend between the firstmentoned cone and the second-mentioned portion having the proximate form of a cone, said pen point being further provided with passages `disposed upon different sides of said rst-mentioned portion and'extending to the end of said second-mentioned portion, each of said passages being bent in order to conserve a sup ly of ink.
