Fig. 3 illustrates thepointin both directions, by being provided with projecting member together with the sleeve an offset portion 21 playing between the 100 for operating the same, and Fig. 4 is a side rear end of the tongue l13 and the front end `view of the magazine taken at right angles of the tube 20, the distance of movement beto that shown in Fig. 1. ing such that when the pusher 14 has ar- Referring to the drawings., 10 denotes a rived in the positionshown in Fig. 2, furtube which serves as a magazine for a series thervmovement in that direction willA be j of successively disposed marking points, the checked by the odset 21 coming into en@ front end of said tube being preferably slit-y gagement with the end of the tongue 13, as

ted, as at 11, to form a pair of spring jaws clearly `shown in that lfigure. Here it will also be noted that the tongue 13 has been instrumental in deflecting the end 14 of the pusher inwardly so that no w this end rests against the butt end of the newly projected point p near the central position thereof. It is therefore evident that considerable friction is established between the bent portion of the pusher and the tongue 13, so that if the pusher is left in the position shown, it will serve as a backing to prevent the marking point p from being accidentally pushed back in the magazine.

gain referring to F ig. 1 it will be noted the offset 21 is in engagement with one edge of the sleeve or tube 20 which is secured to the magazine 10 and therefore serves as a stop for the rearward movement of the pusher 14. At this time it will also be noted that the pusher point 14 is entirely clear of the inside of the magazine 10, so that the marking points p-p are at liberty to gravitate toward the front end. If at any time it should be desired to withdraw the projecting marking point p of Fig. 2, it will first become necessary to rethat tract the pusher into the position shown in Fig.` 1, whereupon the marking point p may be pushed back into the magazine by hand.

1n brief, the present invention comprises a magazine pencil the salient features of which consist of the magazine proper having at one end thereof means for positively bringing the point-projecting member into engagement with the next succeeding marking point within the magazine, the bend formed in the pusher being such as to establish considerable friction between the magazine tongue and the pusher so that the latter may then serve as a backing member for the point in actual use.

Changes may be made in the particular construction of the pusher and especially in the offset portion 21 thereof, as well as in the means whereby the movement of this offset portion is limited to certain predetermined positions in conformity with the length of the marking points used in the magazine, without departing from the spirit of the invention.

l claim 1. A lead pencil comprising a magazine adapted to receive a series of individual marking points gravitative therein, and having near its discharge end an outwardly bent tongue, and a pusher movable longitudinally of said magazine and having its front end constantly in sliding engagement with the underside of said tongue to guide the pusher into contact with the rear end of one of the marking points in the magazine.

2. A lead pencil comprising a magazine adapted to receive a series of individual marking points gravitative therein, and having near its discharge end an outwardly end constantly bent tongue, and a pusher movable longitudinally of said magazine and having its resilient front end in sliding engagement with the underside of said tongue to guide the pusher into contact one of the marking points in the magazine, and means for guiding said pusher on the outer face of said magazine.

3. A lead pencil comprising a magazine adapted to receive a series of individual marking points gravitative therein, and having nearits discharge end an outwardly bent tongue', a' pusher movable longitudinally of said magazine and having its front end in sliding engagement with the underside of said tongue to guide the pusher into `contact with the rear end of one of the marking points in the magazine, and grooved collars eXteriorly on the magazine for guiding said pusher on the magazine.

4. A lead pencil comprising a magazine adapted to receive a serieskof individual marking points gravitative therein, and having near its discharge end an outwardly bent tongue, a pusher movable longitudinally of said magazine and having its front end constantly in sliding engagement with the underside of said tongue to guide the pusher into contact with the rear end of one of the marking points in the magazine, and means for limiting the movement of said pusher in opposite directions.

5. A lead pencil comprising a magazine adapted to receive a series of individual marking points having near its discharge end an outwardly bent tongue, a pusher movable longitudinally of said magazine and having its front end constantly insliding engagement with the underside of said tongue to guide the pusher into contact with the rear end of one of the marking points in the magazine, said pusher having a radial projection adapted to engage the end of said tongue to limit its ejecting movement, and a stationary member on the magazine for limiting the movement of said pusher in the lopposite direction to clear the path of the marking points.

(3. A lead pencil comprising a magazine adapted to receive a series of individual marking points gravitative therein, and having near its discharge end an outwardly bent tongue, a pusher movable longitudinally of said magazine and having its front in sliding engagement with the underside of said tongue to guide the pusher into contact with the rear end of one of the marking points in the magazine, said magazine having at itsrear end a collar provided in a groove to receive and guide the rear end 'of said pusher.

7. A lead pencil comprising a magazine adapted to receive a series of individual marking points gravitative therein, and having near its discharge end an outwardly with the rear end of gravitative therein, and

-' Contact with the rear end bent tongue, a pusher movable longitudinally of said magazine and having its front end in sliding engagement with the underside of said tongue to guide the pusher into of one of the marking points in the magazine, grooved collars exteriorly on the magazine for guiding said pusher on the magazine, and tubular members surrounding said collars to maintain said pusher Within said grooves. 10
