MULTICOLOR PEN Filed June y16, 1931 INVENTOR TTORNEY Patented May 3,v 1932 OTTO RESE, OF WILMINGTON, DELAWARE MULTICOLOR PEN Application led June 16,

The object of the invention is to provide improvements in pens broad1y,-but more especially in that type which is designed to dis ense inks of more than a single color.

umerous attempts have been made to perfect a pen of this type, which will render long l service without requiring repair or cleaning,

which will be positive in its action and not Q k liable to fail in operation, and which is so constructed that no lugs, knobs, or other form of pen-shifting means will protrude exteriorly and therefore-be liable to engage or entangle in ones clothing, the only relatively movable part for shifting the pens being.

a circumferentially continuous sleeve of substantially the same diameter as the exterior of the main portion of the pen barrel.

Another and more specific object is to provide in such a device a sleeve or the like, provided with a cam surface adapted to successively cooperate with each o-f the pen supports present, means connected with each pen support and engaging the cam surface in rotation for ejection and/or withdrawal of the individual pen supports and pens carried thereby into operative or i-noperative position selectively, and resilient means to return an outwardlyshifted pen and its' support toretracted position, when the cam is not doublel acting, said pens being in operative relation to their respective reservolrs when 1n extended or operatlve position for wrlting pur- Y poses.

With these and other objectsin mind the l present invention comprises further details of construction and operation, which are fully brought out in the following description, when read in conjunction with the accompanying drawings, in which Fig. 1 is an elevational view of one embodiment of the invention comprising a multicolor pen in spaced relation with its protective cap; Fig. 2 is an end elevation of the pen with the cap removed; Fig. 3 is an enlarged fragmentary sectional view of the operating end portion on the line 3 3 of Fig. 2; and Fig. 4 is a transverse section of th pen upon the line 4-4 ofFig. 3.

Referring to the drawings, a barrel is provided, the same comprising a tube' 1, normally 193,1. Serial N'o. 544,725.

closed at one end by ya plug or cap 2, and con-` taining a plurality of liquid containers or reservoirs 3, which may be filled when empty in any desired manner. The opposite end of said tube is spanned by means of a closure 4, having an outer threaded surface 5 for detachably securing the protective cap 6 to said v barrel;

Said last-named closure also comprises a. reduced end portion 7 which extends into the tube 1 and inV fixed relation therewith, the

opposite portion of said closure being provided with an inwardly tapering conical recess 8 surrounding an annular planular portion 9, bores 10 extending through said closure into communication with the interior of the tube 1. Centrally, saidlast-named closure is also provided with a'conical extension 11, through which extends an axial bore 12 normally containing a suitabley bolt 13, for securing to said closure a terminal member 14. Said terminal member is preferably, though not necessarily, conical and is provided with a plurality of converging bores' 15, in alignment with the bores l() in the adjacent closure. However, said bores l5 merge into restricted extensions 16 thereof, which latter project through the free end portion of said terminal member, in fact emerge through the end surface 17, which if desired may be surrounde by an annular protective flangelS.

The terminal member 14 is at all times (eX- cept for repair or replacement) firmly secured to the closure 4, and between an annular cutout surface 19 in the former and the conical surface 8 of the latter is rotatably positioned a sleeve 20, which forms a virtual continuation of the two connected members, but does not extend materially beyond them radially. Said member is substantially cylindrical internally, as indicated at 21, but is provided with a radially inwardly extending enlargement 22, which provides for a spiral cam surface 23. Pen holders or tubular styli 24 extend through the converging bores 16 in said terminal member and are respectively provided -`with writing points or pen equivalents 25. The inner surface of each of these styli is partially closedby means of a recouter surface an anti-friction roller or the like 27, which bears directly against the cam surface 23. i

Each of the closures 26 is provided with a.v

bore 28 through which slidably extends arubber or metal capillary tube 29, or other means for conducting iuidfrom the reservoirs 3 into the respective styli 24. lA compression coil spring 30 surrounding each stylus within its corresponding bore 15 normally forces the roller supporting cap inwardly, so that said roller constantly and uniformly engages said cam.

It is lto be understood however that the cam surface 23 extends throughout only a portion of the circumference of the sleeve 20, and in the case where there are three styli, such cam surface would extend throughout only onethird of said circumference, in order that one such stylus will be in extended position, as shown in Fig. 3, While the remaining two styli will be in retracted position as also shown in that ligure. This is but representative and would be altered in conformity With any variation of the number of st-yli embodied in a multi-color pen of this type.

In the operationA of this device, it will be v noted that the reservoirs are in constant coinj the capillary tubes 29, and if inks of differ-- munication with the respective styli through ent `colors are placed Within said reservoirs, the corresponding styli will permit Writing With the correspondinglyv colored inks, only onecolor however'being available at a given time, depending upon which stylus is in extended position by reason of the angular position of the sleeve 20 as manually rotated or oscillated. y y

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United Statesis 1. A fountain pen, comprising a holder, three or more pen supports, a single rotary means to project said supports selectively,-

when one support is being projected the other supports being stationary in Withdrawn position and independent reservoirs in operative communication With'the respective pen supports.

2r. A fountain pen, comprising a holder, a plurality of pen supports, al rotary member carried by .said holder and itself provided with a cam surface operative to move said pen supports selectively in one direction, and independent reservoirs in operative communication with the respective pen supports, said member surrounding portions of said reservoirs.

3. A fountain pen, comprising a holder, a j plurality of pen supports, a rotary member carried by said holder and itself provided with a cam surface operative to move said' pen direction without changing the direction of movement of said member, separate means to automatically -move a pen support in the opposite direction after having been shifted by ,said.cam, and independent reservoirs in 'operative communication with the respective pen supports.

4. A fountain pen, comprising a holder, a plurality of pen supports carried by said holder, an oscillatory sleeve also carried by said holder and provided with means to shift said pen supports inone-directiop selectively, separate means to return said supports to a retracted position after having been shifted therefrom, and independent reservoirs operatively connected to said supports and housed Within said holder.
