The present invention relates to a writing instrument and more particularly to one of the pen or pencil type in which a plurality of marking or writing elements are selectively arranged for use, one object being to provide an improved writing instrument of this class which is simple in construction, convenient to operate, comparatively inexpensive to manufacture and efficient in service.

Another object of the invention is to provide a pencil of the magazine type in a compact, durable and easily adjustable form which can be quickly filled with different colored leads ready for immediate use and having means by which to conveniently select and move the different leads to writing position.

A further object of the invention is to provide a-pencil of the magazine type having a plurality of lead carriers adapted when not in use to have an off-center position Within the casing or barrel and adapted to extend substantially the full length thereof .to inrrease the carrying capacity of the pencil and being arranged to have cnsiderable lateral play at their points of support whereby the writing end of any one selected for use is adapted to readily move into central position within the casing when advanced to writing position therein.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

Similar re ference numerals throughout the several views indicate the same parts.

The present invention embodies a writing instrument of the pencil type designed to have a minimum numberyof parts which can be easily assembled and cheaply manufactured and one which is capable of holding a plurality of different colored leads or marking elements, any one of which may be selected and presented for use by a simple adjustment of parts. The adjustments are preferably all made from the outer end of the pencil thereby leaving the barrel or casing free to be held in one hand `while the fingers of the other hand are en'iployed to make the required adjustments for moving the selected lead to writing position.

Referring to the drawings, 1() represents a barrel or casing having the usual tapered writing end 11 with a reduced opening 12 of a size corresponding substantially to the diameter of the magazines or lead carriers 13, three of which are shown and all being of the same construction, it being understood that a greater or less number may be employed if desired. The magazines are in the form of hollow tubes, preferably constructed of thin sheet metal and are slightly tapered at their Writing ends, as indicated at 14 and being split at their forward extremities in the usual manner to form gripping fingers for the lead or marking elements carried therein and indicated at 15. The leads are preferably of different colors, as for example, red, green, and black, though other color combinations may be used, or if preferred all of the leads may be of the same color. The inner diameters of the magazine tubes or carriers are slightly larger than the diameters of the different leads therein, except at the tapered ends of the tubes where the yieldable fingers are adapted to frictonally engage and hold the leads when fed therethrough. Each carrier has a follower 16 disposed therein for advancing the lead to writing position as shown in Figure 3 in a manner which will be hereinafter described.

Each follower carries at its outer end a laterally projecting or angularly disposed finger or lug 17 which projects through aI longitudinally extending slot 18 of the carrier tube for cooperation with suitable propelling means hereinafter described, the free ends of the fingers being rounded or beveled on one or more sides to facilitate engagement with said propelling means.

The magazines or carriers are all preferably supported by a common control member in the form of a holder rotatably mounted upon the outer end of the casing and comprising an outer cylindrical portion 19 which projects from the casing and an inner portion indicated generally at 20 which projects into the casing and is held therein by frictional engagement with the walls thereof upon which it is free to rotate. The inwardly projecting portion 20 comprises three tube-like sections 21 shaped as best indicated in Figures 4 and 6 and through each of which extends the outer end of one of the tubular carriers 13, the carriers being extended into the cylindrical portion 19 of the holder as shown in Figure 3. The carriers are slightly smaller in diameter than the openings of the tubular sections 21 through which they project whereby suficient play is allowedto permit their Writing ends to swing into the center of the pencil point 11 as shown in Figure 3. Thus, flexing or bending of the carrier tubes is prevented in moving them to writing position whereby breaking of the lead is avoided.

The outer ends ofthe carriers which extend into the cylindrical portion 19 of the holder are provided with laterally projecting operating pins 22 which project through longitudinally extending slots 23 in the holder and have buttons or knobs 24 thereon by which to more conveniently move the tubes to and from writing position longitudinally of the casing and of the holder as well. The slots 23 terminate at their forward ends in circumferentially extending portions 25 so that when the pins 22 are moved therein the lead holding tubes are given a rotating or turning movement around the cylindrical portion 19 of the holder so as to swing or rotate the carrier and its follower to and from Operative relation with respect to suitable propelling or advancing means for the follower which serves to move the lead' to writing position as shown in Figure 3. The propelling means may be of any suitable type, such for example, as the spirally wound spring 26 which fits snugly within the casing 10 and extends from the base of the tapered portion 11 thereof to the inner end portion 20 of the magazine holder, the spring being held against;l rotation by frictional engagement with the walls of the casing. The slots 23 are so arranged that when the pins or projections 22 of the carriersare located therein the lugs or fingers 17 are adapted to lie in grooves 27 formed between the tubular secboth in Figures 5 and 6, in which position the fingers are disengaged from the propelling means, comprising in the present instance, the spring 26. Upon movement of the pin 22 of any one of the carrier tubes into the slot 25, rotation of the carrier is effected and the finger 17 is thus moved out of the groove 27 into position between the coils of the spring so that subsequent rotation of the magazine holder causes the follower of the adjusted magazine to be advanced -and likewise the lead within said carrier. Advancement of the follower is of course, due to rotation of the finger 17 of the selected earrier in contact with the coils of the spring. However, since the fingers of the remaining followers are not adjusted into position between the spring coils said followers will not be advanced, although they, together with the carriers on which they are mounted are rotated simultaneously with the selected carrier' upon rotation of the magazine holder or control member 19.

As before stated, the buttons or knobs 24 are given the desired colors and the corresponding magazines are loaded with like colored leads, which can be readily inserted through thin forward ends so that it is easy to select the color desired and by pushing the selected button forwardly and turning it to the right until it occupies the position shown in Figure 1, and thereafter rotating the magazine holder, the lead is extended to writing position. When through writing with a lead of a given color the button is moved from the position shown in Figure 1 to that shown in Figure 2, which automatically withdraws the finger 17 from engagement with the spring and returns it to inoperative position within the recess 27 as shown in Figure 6. Should it be desired to continue writing, but with a lead of a different color, the button corresponding to the newly selected color will be pushed forward to the position shown in Figure 1 and the magazine holder then rotated as in the previously described operation. y

The magazine holder may be constructed in any desired manner 4but preferably comprises a one-piece tube, the outer end of which is slotted as shown and the inner end shaped by the use of suitable dies or otherwise to form the tubular sections 21 and grooves 27 therebetween the dies forcing the metal inwardly at the three points indicated in Figure 6 whereby openings for the Carrier tubes of the proper size are afforded.

From the particular construction shown it tions 21 of the magazine holder as shown lll lll

will be seen that van advantage is afforded by having the magazine equal the length of the,Y

casing and substantially the length of the pencil whereby its lead holding capacity is increased and the number of parts reduced."

Another advantage is in constructing the holder so that each magazine can freely move thereon from a normal off-center position to a central writing position at its forward end and vice-versa whereby flexing of the carriers may be avoided and the consequent danger of breaking the leads therein. l

A still` further advantage of the present construction is that all of the manually operable 'parts are located at one point and this is particularly true since they are disposed at the outer end of the pencil, thus permitting the entire barrel or casing to be grippedy in one hand while the lingers of the other hand are used to adjust the buttons and to rotate the magazine holder.
