'Rigidly inserted or fastened interiorly of the se The pencil has a casing (1) which in the tip (20) is a second portion (21) adapted to close the forward end of the magazine, and said portion has a notch (21A) adapted to receive soldered or otherwisely fastened thereto, a lead receiving and retaining tubing (22) having its inlet portion flush with the front wall of portion (21) and in depending line with the channel, or groove (3). Said tubing, has an end portion (22A) projecting outwardly from the tubular tip, as more particularly shown in Figs. 1, and 2. Thetubing, is preferably split at (2213) as shown in Fig- 5, forming lead retaining means. In order to removably secure said tip on the forward end portion of the magazine, as shown. in Fig. 1, I provide one or more tongues (23) which may be stamped integral with, or fastened on the casing, and the tongues are preferably formed each with a protuberance (23A) adapted to engage, or be en aged by locking openings (24) which are provided on the elliptical portion'of the removable tip, as shown in Fig. 4, so that by pressing the protuberfor access to said magazine.

The push rod, or plunger guided in channels or grooves and (4:) enters the magazine thru a notch (1AA) formed at the elliptical periphery of partition (14) and in registerwith channel or groove engaging and forwardly pushing one of the leads contained in the magazine, which lead having by gravity entered groove portion within the magazine as shown in Figs. 2, and 7, pushing the lead forwardly thru tubing (22) out wardly of its retaining end portion (22A) ready for use. At the rear end of the casing is a retaining cap (26) formed with fastening openings (27) adapted to receive fastening lugs (28) which are preferably made integral with the casing. Said lugs inserted thru:

said openings, are bent-in recesses (29) provided on said cap thereby fastening the same.

time retaining magazine reserve leads oapacity of the latter. As clearlyillustrated, the

reduced push rod or plunger portion length is such, that its lead engaging end does not retreat beyond the approximate middle portion of notch (14A) when the cutting portion of the rod or plunger is completely projected rearwardly of the casing, as well as said cutting portion is to be completely within the casing, when a new lead fed by the rod or,

plunger portion, has reached writing poing a new lead thru the tip, when a new lead may then be undesired. I

It is thought that the operation, and construction of this pencil is obvious from the above description, in which a comparatively simple self-feed-magazine-pencil has been outlined composed of few simple, and durable parts forming a convenient, compact combination of three-devices in one,without sacri ficing the magazine leads capacity, due to the fact that there are no parts occupying space interiorly of the magazine.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be misunderstood as limiting myself theretoas I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope of the claims. j 7
