June 23, 959 H. WENGELER ET AL FOUNTAIN TYPE WRITING INSTRUMENT Fl'ed March 29, 1956 F Im w m fengeier Gre ATTXS.

United States Patent 2,891,272 FOUNTAIN TYPE WRITING INSTRUMENT Herbert Wengeler, Marburg an der Lahn, and Josef Grebner, Numberg, Germany Application March 29, 1956, Serial No. 574,702 Claims priority, application Germany April 1, 1955 1 Claim. (Cl. 15-133) This invention relates to writing instruments, and more specifically to a fountain type writing instrument.

The object of the invention is to provide a fountain type writing instrument for the lettering of wagon slips for railroad cars and the like, which can at the same time be used with advantage for the lettering and painting of smooth surfaces of glass, china, wood or cardboard, e.g. file covers, and for producing large-scale sketches and drawings on such surfaces, and may furthermore be used for applying caustic liquids or solvents and writing Chinese characters.

The novel fountain type writing instrument having a writing liquid reservoir of the kind which is known from fountain pens, and from which writing liquid flows to one end of the instrument, is substantially characterized according to the invention in that an actually writing element is formed by a brush composed of natural or synthetic bristles, e.g. of perlon, nylon or another resistant polyamide material, or of metal such as steel, or any absorptive material, which writing element is accommodated in a guide sleeve and is shiftable or screwable therein in the longitudinal direction thereof, so that the writing tip of the brush projecting from said guide sleeve can be set at will.

The bristles of the brush are preferably secured, e.g. by way of gluing, in a cylindrical socket which is shiftable or screwable in the guide sleeve in the longitudinal direction thereof. On its outer surface the cylindrical socket is provided with grooves which may extend in a spiral path and which serve for guiding the writing liquid, for example ink, from the liquid reservoir to the brush.

Several preferred embodiments of the invention are illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a section along the central longitudinal axis of a fountain type writing instrument, showing on an enlarged scale the writing end thereof;

Fig. 2 is a `side elevational view of the writing instrument in natural size, with closing cap detached;

Fig. 3 is a section through the writing end with a brush having a rectangular cross section and a flat writing tip;

Fig. 4 is an end view of the writing end with a brush having a rectangular cross section and a tip forming a blunt angle;

Fig. 5 is a fractional view of Fig. 4.

A blush 1 composed of, for example, bristles made of perlon, fabric or the like, is secured, e.g. by way of gluing, with one of its ends in a cylindrical socket 2, whereas the opposite end of the brush 1 forms a writing tip` 7. The socket 2 has an external screw thread 3 and is on its outer surface provided with at least one groove 4 through which writing liquid may flow from a writing liquid reservoir 5 in the elongated housing to the brush 1 due to the cap- Patented June 23, 1959 illary attraction and the pump action effected by the bristles bending outwards when being subjected to presf sure during the writing operation. The socket 2 is held in a circular or elliptical guide sleeve 6 by its threads 3 and can be screwed or shifted, respectively, in the longitudinal direction thereof, so that the writing tip 7 on the brush 1 projecting from the guide sleeve 6 can be ad justed, i.e. extended or shortened, as desired. The guide sleeve 6 is adjustably threaded as at 6a in one end of the elongated housing 10, while a closure cap 11 is rotatably mounted on the housing to cover the writing tip 7 with an absorbent packing 12 therein to absorb excess ink from the writing tip.

By means of the writing tip` 7 which can be adjusted according to the desired purpose and used in connection with fountain ink or other suitable writing substances, lettering, painting and similar operations4 can be carried out in a satisfactory manner.

In the embodiment shown in Figs. 3 to 5, exclusively, brushes wil be used which are composed of synthetic bristles not being subjected to wear so that the means for extending or shortening the writing tips on the brushes may be dispensed with.

Although preferred embodiments of the invention have been described in detail herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to these precise embodiments, particularly with respect to the materials specified in connection therewith, and that various changes and modifications may be eifected therein, without departing from the scope or spirit of the invention as defined in the appended claims.

We claim:

A fountain type writing instrument, particularly for the lettering of wagon slips for railroad cars and the like, comprising in combination an elongated housing, a. writing liquid reservoir in said housing, a guide sleeve longitudinally adjustable in one end of said housing, a writing element adjustably extending through said guide sleeve and spaced therefrom along the major portion thereof and closely fitting the outer end of the guide sleeve to provide a chamber for the collection of writing fluid surrounding the writing element, said writing element forming at its outer end a writing tip projecting from said guide sleeve, means for adjustably securing the opposite end of said writing element in the inner end of said guide sleeve for adjusting said writing element relatively to said guide sleeve in the longitudinal direction thereof, comprising a cylindrical socket adjustable in said guide sleeve in the longitudinal direction thereof with the writing element secured in the cylindrical socket, said socket having an external spiral groove to feed writing iiuid from the reservoir to the writing element and a cap closing said elongated housing and overlying said writing tip.
