MAGAZINE PENCIL.

Application med March 22, 1926. serial No. 96,633.

This invention relates to lead pencils, and particularly to that type in which the leads within the opening 11. The other end of the shell is externally threaded, as shown in are contained within a casing and are prothe drawing. pelled, or fed, when required, through a\\` Disposed within the shell, and fitting suitable guide and through a pointed end or nozzle, in such manner that thevouter end of the lead shall project only a short distance beyond the tip of the nozzle so that while suiiiciently exposed, for writing purposes, it is not liable to easy breakage.

The principal object of the invention is to provide alead supporting and feeding unit, which is arranged to be slipped into the shell of the pencil, whereby simplicity, as well as cheapness in the cost of manufacture, will result.

Another object of the invention is to provide a pencil of this character which has a magazine for spare leads, vsuch magazine leads may be brought into position for projection without the necessity of opening the pencil case, or disconnecting any part or parts thereof.

this character wherein the entire,pencil is adapted to be rotated or manipulated, to dispose a fresh lead in position for projection, thus obviating the necessity of independent movement of any of the parts of the pencil.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a plan view of the pencil.

Figure 2 is an enlarged longitudinal sectional view on the line 2-2 ofFigure 1.

Figure 3 is an enlarged transverse sectional view on the line 3-3 of Figure 1.

Figure 4 is a perspective view of the in ternal unit removed from the shell, and partly broken away `to show the projector and operating means therefor.

Referring particularly to the accompany- -ing drawing, 10 represents a tubular shell having one end tapered, as at 11, to form av nozzle, and having the opening 11 in the tip thereof. Disposed transversely within the shell, inwardly of the tapered end, is a centrally apertured wall 12, and secured at one end in the opening of the wall is a tube 13, the other end thereof being secured being associated with means whereby freshA Another object is to provide a device of snugly therein, is the lead manipulating unit of the pencil which includes a cylindrical magazine 14, and formed longitudinally 1n the outer face of said magazine is a groove 15, which results in an inner longitudinal. rib 16. Inwardly extending bosses,I or projections 10', formed in the shell 10, enter the groove 15, for the purpose of preventing rotation of the magazine therein, and also as a guide in placing a fresh lead in position for projection, as will vbe explained later herein. Disposed longitudinally and centrally within the magazine 14 1s a lead receiving channeled member 17, the open side of the channel of which is slightly offset from said rib 16, whereby the rib is in position to cause leads, which are contained in the magazine 14, to roll singly, into said channel. The outer end of the channeled member 17 projects a short distance beyond the corresponding end of the magazine, and is tapered' so as to seat within the flared end of the tube 13, -for the purpose of properly supporting and centering this end of the unit, and for alining it with the discharge opening of tlie nozzle. The channeled member 17 is also extended rearwardly beyond the otherend of the magazine 14, as shown at 18, and is properly secured within the adjacent end of the magazine. This extension is of such length that when the unitisl properly disposed within the shell, saidextension will project a distance beyond the externally threaded end of the shell. Surrounding the extension 18, and spaced a short distance from the adjacent end of the magazine 14, is a sleeve 19, and encircling the extension, between the sleeve and the magazine, is a coil spring 21, which bears against the magazine, and a washer 20, at its opposite ends. The other end of the sleeve 19 is provided with an external fiange 22, and secured on the sleeve, in spaced relation to the flange, is a tubular eraser holder 23. 4Rotatably supported on the sleeve 19, between the member 23 and the flange 22, is an internally threaded cap 24, which engages on the threaded end of the shell, to hold the unit in proper position within the shell. The

sleeve 19 is internally threaded, by piessing a spiral rib and groove therein, such groove, shown at 19, being located in the inner face of the sleeve. The extension 18 is formed With a longitudinal gioove 26 in which is disposed vthe lead projecting plunger 27,

Asaid plunger having outer end turned anguof the extension 18, beyond the adjacent end of the sleeve 19, is provided with a transverse pin 29, which bears against a washer 30 seated on the adjacent end of the sleeve.

The spring 21 normally exerts force to move the members 17 and 19 longitudinally With respect to each other for the purpose of frictionally holding the sleeve against accidental rotation. A removable cap 31 is engaged in covering relation to the eraser holder 23, being frictionally held thereon and adapted to be grasped to turn the sleeve 19.

In the operation of the device, when a lead has been practically used up, the operator rotates the sleeve 19 in a ietrograde direction to Withdraw the plunger 27 rearwardly out of the channel of the member 17. The operator, after so positioning the pencil that the bosseslO are uppermost, rotates the pencil in a clock-Wise direction until the bosses are again uppermost. This rotation of the pencil causes 'the leads to roll around in the magazine so that the foremost ot said leads will be stopped by the ribs 16, and guided into the channel of the member 17. The cap is then grasped and the sleeve 19 rotated until the lead is projected from the nozzle to the desired distance for Writing.

Attention is particularly called to the factl that the entire lead holding, lguiding, and projecting mechanism forms a unit which is readily inserted or removed by simply disengagingor engaging the threaded cap.
