SPECIFICATION forming part of Letters Patent No. 584,999, dated June 22, 1897.

Application filed December 23,1893. Serial No. 494,548. (No model.)

.T7 (LZZ whom, it may concern-f Be it known that we, BYRON BENJAMIN GOLDSMITH, a resident of New York, in the county and State of New York, and lVILLIAM BURT, a resident of Jersey City,county of H udson, State of New Jersey, have invented certain new and useful Improvements in Magazine Lead-Pencils, of which the following is a specification.

Io Our invention has reference to improvements in magazine-pencils in which a series of individual marking-points are stored in a magazine and by a simple manipulation of the device are forcibly projected in position I5 for use and the used-up or broken markingpoints are forcibly ejected.

A characteristic feature of our invention is that the individual marking-points are stored in a magazine-tube which is movable longizo tudinally with reference to the mantle or holder of the pencil and that the ejector may be either immovable with reference to the Inagazine-tube or may also be movable with reference to and with the same. The arrangement may be such that the movement of the magazine-tube or of both the magazinetube and the ejector in both directions is effected positively by the operator, or by preference the arrangement may be such that 3o only the movement in` one direction is effected positively by the operator and the movement in the other direction is produced by a spring. These and other improvements will more fully appear from the following detail description, with reference to the accompanying drawings, in which- Figures l, 2, and 3 represent longitudinal sections of one form of our magazine-pencil with amovable magazine-tube and relatively 4o immovable ejector. Figs. 4 and 5 represent like views of a modified form of our magazine-pencil in which both the magazine-tube and the ejector are movable with reference to and with each other. Fig-6 is a longitudinal section of a modified construction of the feeding end of the magazine-pencil, and Fig. 7 is an elevation of the same.

Like numerals of reference indicate like parts all throughout the drawings.

5o Referring now particularly to Figs. 1, 2, and 3, the/ main body of the magazine-pencil is shown as la mantle l, which may be of wood or metal or other suitable material, and which has mounted at the forward end a nozzle 2 and at the rearward end a sleeve 3, the rear n edge 4 of which is turned inwardly, as shown. The nozzle 2 and sleeve 3 are fast on the mantle, so that they may be considered as a portion of the latter. The rear end of the mantle proper thus forms a ledge 5, which serves 6o as a support for a flange 6 on the ejector-tube 7, which extends Centrally through the mantle and has formed at its forward end springfingers S 8, which are bent inwardly for a purpose which will vpresently appear.

Through the ejector-tube7 extends the magazine-tube 9, formed at its forward end, which projects through the nozzle 2, with spring-jaws 10 10, formed in the rear of the front end with beads 1l 1l. In the normal 7o position of the parts this magazine-tube is in the location shown in Fig. l-that is to say, the tube is in its rearmost position, with the beads l1 pressed against the front edge of the nozzle, so that the spring-jaws 10 are 75 thereby compressed and tightly hold an individ ual marking-point l2. This magazinetube is so long that with its rear end it projects beyond the sleeve 3. It has a free opening at that end, through which the series of So individual marking-points are fed into the magazine-tube. Loosely fitted into the sleeve 3 is the pushpiece 13. This is a tube of a diameter to push through the inturned edge 4 of the 85 sleeve 3, but having the inner end expanded, as shown at 14, so as to loosely t the inner face of the sleeve. In this manner there is an offset or ledge formed between the wider and the narrower portions of the push-piece, 9o whereby the latter is prevented from being drawn out of the sleeve 3, but can be moved freely to and fro in said sleeve. Upon the magazine-tube there is iixed a disk or washer 15, and between this disk or Washer and the flange 6 on the ejector-tube and surrounding the magazine-tube is inserted ahelical spring 16, which in the normal position of the parts is expanded, thus holding the magazine-tube in its most rearward position with the beads 1l forced against the front edge of the nozzle and holding the ejector-tube in its most IOO forward position with the flange G against the ledge 5. The ejector-tube is always in this position the same as if it were fixed to the mantle, and it may conveniently be fixed to the sam e. In the drawings we have shown the disk or washer 15 bearing against the offset between the wider and narrower portions of the push-piece 13, but it may just as well be made large enough to bear against the inner edge of the push-piece. The push-piece is closed by a removable thimble 17, which thus serves as a thumb-piece upon which the finger of the operator presses for forcing the push-piece inwardly. This tliimble is removed when the magazine-tube is to be filled.

Midway between the two ends of the ejector-tube there is formed in the latter a longitudinal slot 18, into which projects a tooth 10, st-ruck u p from the magazine-tube, as shown. The foiwvard-and-backward movement of the magazine-tube is thus limited by the length of the slot 18.

A short distance behind the beads 11 on the spring-jaws of the magazine-tube there are formed in the latter two diametrically opposite longitudinal slots 2O 20, into and through which the spring-fingers 8, formed at the forward end of the ejector-tube, normally project.

Fig. 1 represents the device with the parts in their normal positions. It shows the magazine-tube filled with individual markingpoints, but the parts are in the same position as when the magazine-tube is empty. The magazine-tube is filled, as above stated, by removing the thimble 17 and then dropping the marking-points down into the tube with their points forward. The first markingpoint dropped into the tube is arrested by the spring-fingers 8 of the ejector, which spring-fingers project through the slots 2O into the magazine. The other inarking-points thus become arranged in a series one behind the other, each with its point resting upon the butt-end of the preceding marker. In this condition of the device the magazinetube isin its rearmost position with the tooth 1f) at the rear end of the slot 18, and it is understood that the pencil is held vertically, or nearly so, with the forward end downward. After the magazine-tube has thus been filled, or nearly filled, the thimble 17 may again be put in place, and the user, grasping the mantle, presses with one of his lingers upon the thimble, thus forcing the push-piece 13 inwardly, which carries with it the magazinetube and compresses the spring 16 between the flange 6 and the washer 15, as shown in Fig. until the tooth 1f) is arrested by the forward end of the slot 18. The magazinetube is thereby projected through the nozzle, and the spring-fingers 8 of the ejector ride upon the solid portion of the magazine-tube and are thus withdrawn from the slots 2O 20 and do not impede the further forward movement of the series of marking-points behind the same. These marking-points, therefore,

l now drop down into the forward portion of the inagazine-tubc, without, however, dropping out of the same, since the spring-jaws l0 10 are so constructed as to always close su fiieiently to prevent the free movement of the markingpoints between the same. The pressure of the finger upon the push-piece is now removed and the spring 1G, again expanding, carries the inagazinc-tube back into the position shown in Fig. l. Midway between these two positions the parts have the relation shown in Fig. S-that is to say, the tooth 19 is in about the middle of the slot 18, while the springfingers 8, having again passed through the slots 20, bear upon the butt-end of one of the marking-points. As the magazine-tube still further retreats, the markingpoints in front of the spring-fingers of the ejector are held stationary and the magazinetube is drawn back over the saine until the foremost marking-point is projected in position for use between the spring-jaws 10 10, which now tightly close upon that forward marking-point by reason of the beads 11 11 bearing upon the front edge of the nozzle. A repetition of the reciprocating movement of the magazine-tube operates, in conjunction with the ejector, to forcibly eject the foremost marking-point and to forcibly project the one immediately behind it in position for use.

It will now be understood how a forward marking-point, after having been used up so as to become dull, can be ejected forcibly and how a new point is projected forcibly in position for use. All that is necessary is that the device be held with the nozzle downward and that the push-piece be pressed down with one finger to the end of its stroke (which is limited by the slot 18 and tooth 10) and that the push-piece be then released.

Itis not absolutely necessary that the magazine-tube in its normal position shall project beyond the nozzle, since it may be constructed so as to be normally flush with the nozzle, in which case, of course, the beads 11 11 will or may be omitted. In that case, however, the spring-jaws 10 10 will be made to hold the foremost marking-point, when in position for use, sufficiently tight to prevent this point from falling out. If this construction is adopted without other change in the proportions of the parts, there will normally be only two points in advance of the spring-fingers 8, but the proportions may be slightly changed so as to have only a single marking-pointnamely, the one which is in position for usein advance of the spring-fingers 8; or the magazine-tube may be made to normally project beyond theV nozzle, as shown, but without the beads 11, since the function of these beads is only to cause the spring-jaws to more tightly grasp and hold the forward markingpoint when the magazine-tube is in the retracted position. This additional tightening may be dispensed with.

Figs. 4 and 5 illustrate another form of our IOO invention in which both the magazine-tube and the ejector are movable relative to each other, and also movable with each other relative to the mantle or case. In this case the mantle 1 is preferably made of sheet metal, although it may be made of other material. The nozzle 2, which extends rearwardly in the shape of a tube, is held in the mantle either by friction only or is otherwise secured to the same, and the same is true of the sleeve 3, which has also an inturned edge 4, as ,in the construction shown in Figs. 1, 2, and The push-piece 13 isv in this case made ratherlong and is closed by the thimble or push-button 17. The washer 15 on the ejector-.tube 7 may be either soldered to the same or may simply be passed over the same against a small bead 15' on the ejector, and this washer or disk 15 bears against the edge of the expanded portion of the push-piece. A second disk or washer 15" is held on or secured to the ejector-tube at a point between the forward end of the slot 1S and the spring-iingers 8, and the helical spring 16, surrounding the ejectortube, bears at one end against this washer 15" and with the other end against the ledge 2, formed in the nozzle where the same expands into a tube.

The magazine-tube 9 is constructed in this instance precisely like the magazine-tube shown in the other figures of drawings, except that it does not project in the rear beyond theV ejector-tube, but, on the contrary, the latter projects beyond the magazine-tube. Immediately in front of the slots 2O 2O in the magazine-tube there is fixed to the latter a small disk or washer 2l, by which the forward movement of the magazine-tube is limited, since upon such forward movement the disk 2l stri kes against the ledge 2' in the nozzle. The rearward movement of the magazine-tube is limited by the beads 11 striking against the front edge of the nozzle. This is the normal position of the parts and is represented in Fig. 4, while Fig. 5 shows the magazine-tube in its forward position, and consequently the disk 21 bearing upon the ledge 2.

The slots 2O and the spring-ingers 8 are so proportioned in length and relative position that in the normal condition of the device the spring-iingers are out of the slots and bear upon the solid portion of the magazine-tube, and in this normal relative position the magazine-tube and ejector are held by the helical spring 16. In that portion of the magazinetube which lies between the disk 21 and the beads 11 there are struck up two springtongues 22 22e which normally project into the magazine-tube and bear against the butt-end of a marking-point, thereby preventing the foremost marking-point from slipping back in the act of writing.

The operation of this form of our magazinepencil will now be readily understood. Supposing the parts to be in their normal position, as shown in Fig. 4, without leads in the maga-zine, the latter is iilled by removing the thimble 17 and dropping the leads into the( tube with their points downward. The first marking-point will be arrested by the springtongues 22, and the others will arrange themselves in series, each with its point against the butt-end of the preceding one. The pusher is then forced down, whereby the spring-lin gers Senter the slots 2O and project through the same until they bear upon the butt-end of a marking-point. Continued pressure upon the push-piece causes the springngers to press upon the forward series of marking-points, and since the latter are held against free forward movement by the springtongues 22 the magazine-tube is forced forwardly until the disk 21 strikes against the ledge 2', as shown in Fig. 5. By this movement of the magazine-tube the spring-jaws 10 are relieved of the compressing action thereon of the nozzle, which now does not bear upon the beads 1l. Still further continued pressure upon the pusher causes the spring-fingers 8 to propel the forward marking-points forwardly and between the springtongues 22, which close again behind the first marking point, preventing the rearward movement of lthe same, while the dropping out of the same is prevented by the springjaws 10, which hold it suiiiciently tight for that purpose. By this time the spring-fingers S have arrived at or near the end of the slots 20, while the tooth 19 is now at the rear end of the slot 18. The forward stroke of the push-piece is thus completed, and the finger being removed from the same the parts are returned by the spring 16 to their original position. (Shown in Fig. 4.) This action is now repeated until the forward marking-point projects from between the jaws 10 sufficiently for use. It will be observed that when the parts are returned to their original position by the action of the spring 16 the foremost marking-point will be grasped very tightly by the spring-jaws by the action of the edge of the nozzle upon the beads 11. It will now be readily understood that when the first marking-point has been used up one stroke of the pusher will at once forcibly eject this marking-point and will project a new marker forcibly in position for use, and that all this is effected by a simple stroke of the pushpiece produced bythe pressure of a finger of the user thereon. We are not limited to the exact details of construction thus far described, since the same may be variously changed without affecting the utility of our magazine-pencil.

An additional improvement we have illustrated in Figs. 6 and 7. The saine has for its object to prevent the user from feeding the individual marking-points into the magazinetube with their butt-ends forward, which with the construction shown in the preceding iigures of drawings might be done and which, if done, would render the pencil in a measure inoperative. This is prevented by the fol.-

lowing construction: The ejector-tube is made IOS) IlO

shorter than in the construction shown in Figs. 4 and 5, so that it will onlyslightly project beyond the lnagazine-tube, and this projecting portion is made iiaring, as indicated in solid lines at 9 in Fig. 6, and the cap or thimble 17 is made long enough to project slightly over the Haring portion of the ejectortube. In the side of the push-piece 13 there is formed a longitudinal slot 23, shaped to the shape of a longitudinal section of a markingpoint with the point downwardly, and in the side of the thimble 17 there is formed a similar slot 24, which when the thimble is suitably turned will register with the slot 23. In addition thereto there is in the side of the thimble 17 a short circumferential slot 25, into which is struck a tooth 26 from the side of the push-piece 13, thus allowing the thimble to turn to the extent of the length of the slot 25, but not allowing it to be removed. The parts are so placed that when the thimble is turned in one direction the

slots

23 and 24 register and when turned in the other direction the lateral feed-opening is closed. Tith this construction the individual marking-points are fed into the magazine-tube by holding the pencil in an inclined position with the point downward and dropping the individual points through the lateral feed-openings 23 24, when, as will now be understood, theyT will slide down into the magazine-tube always with their points downwardly, since they cannot be introduced in the slots 23 24 in the reversed position. An obvious modification of this construction would be to make the ej ector-tuhe as long as in the construction shown in Figs. 4 and 5 and make in the side of that tube another slot similar in shape to the slots 23 24, and this is indicated in dotted lines in Fig. 6. In this construction the thimble must be turned in its bearing, which requires some little force, and it is therefore preferable to make the head of the thimble with milled beads, as shown. Such milled beads may also be used in the other construction shown to facilitate the removal of the thimble 17.

It will be evident that some features of construction shown in Figs. 1, 2, and 3 may be transferred to the form of pencil shown in Figs. 4 and 5, and vice versa. Thus, for instance, while we have shown in Figs. 1, 2, and 3 the actuating-spring 16 placed at the rear end of the pencil and in Figs. 4 and 5 placed at the front end of the pencil, these positions may be reversed. The springtongues 22 shown in the pencil illustrated in Figs. 4 and 5 may also be used in the construction shown in Figs. 1, 2, and 3, whereby the spring-fingers S would be relieved of the back pressure of the pencils in the act of writing. The lateral feed-openin g shown in Figs'. 6 and 7 may be used in connection with both forms of pencil, and numerous other variations will suggest themselves readily to those skilled in the art. Thus, for instance, the spring 16 may be altogether dispensed with, in which case the magazine-tube is moved both forwardly and backwardly by hand. The forward movement would then be effected by the pressure of the iin ger upon the push-piece, as in the case when the spring 1G is used, and is moved rearwardly by taking hold of the projected magazine-tube at the jaws 10 and sliding it back into the mantle. In that case of course the ejector-tube must be fixed in the mantle positively in any suitable n'ianner, since otherwise, the spring 16 being absent, it would or might move with the magazine-tube, which would render the device inoperative. It will also be seen that when the spring 16 is dispensed with the act of writing will prevent the forward markingpoints from receding into the magazine-tube by vbringing the butt end of one of them against the spring-lingers S on the ejector or against the spring-tongues 22, as the case may be.
