MAGAZINE PENCIL Filed Jan. 15, 1930 2 Sheets-Sheet 2 By @Mm A ttorncy Patented May 26, 1931 PATENT OFFICE OSCAR R. EARTH, OIE DETROIT, MICHIGAN MAGAZINE PENCIL Application filed January 13, 1930. Serial No. 420,467.

The present invention relates to pencils and has for its principal object to provide a 1naga zine pencil by means of which a plurality of varied colored leads may he carried within the pencil for selective positioning in the pencil.

A further object is to provide a pencil of this character in which the desired colored lead may be easily and quickly brought into writing position.

A further object is to provide a pencil which is simple and practical in construction, neat and attractive in appearance, eflieient and reliable in performance and otherwise Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a side elevational view,

Figure 2 is a longitudinal sectional view,

Figure 3 is a view in elevation of the lead guide for directing some of the sticks of lead into writing position,

Figure 4 is a similar view of the plug carried in the opposite end of the pencil,

Figures 5 to 9 inclusive are transverse sectional views taken respectively along the line 55, 66, 77, 88 and 9-9 of Figure 2, and

Figure 10 is a group perspective view of one of the lead retaining sleeves and the ram rod for ejecting the lead from the sleeve.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the barrel of the pencil which is of a hollow tubular construction and open at each end, one end of the barrelbeing threaded for receiving the threaded tapered end 6 which is also of hollow construction.

The opposite end of the barrel is fitted with a plug 7 having a shoulder 8 formed thereon engaging the end of the pencil to limit the inward movement of the plug.

In the end of the pencil opposite tron) the plug 7 is carried a lead guide 9 ol' substantially cylindrical formation and having a plurality of spring fingers 10 formed at one end for positioning within the tapered portion of the end 6.

The opposite end of the guide 9 is formed with a step 11 which extends longitudinally of the barrel with its free end inserted in a bore 12 formed in the plug 7. The stem is secured to the plug for movement as a unit by a machine screw 13 threaded through an openin g in the wall of the plug.

The plug and the guide are rotatably carried within the barrel and it will be apparent from the foregoing that upon the turning of the outer end of the plug that the guide will be likewise moved.

The inner ends of the plug 7 and the guide 9 are spaced apart as clearly shown in Figure 2 of the drawings and within the chamber thus provided is fitted a magazine 14 composed of a. plurality of interconnected and concentrically arranged tubes 15 having their inwardly disposed walls open and adapted for receiving sleeve 16 within which the lead 17 is carried.

The magazine 14 is snugly fitted within the barrel so that the walls of the barrel will frictionally engage the tubes of the n'iagazine to prevent idle rotation of the magazine within the barrel.

The guide 9 is formed atone side with a. channel 18 of suiiicient size to enable the sleeve 16 to move longitudinally through the guide when the channel 18 of the guide is in registry with the respective sleeves carried by the magazine. Accordingly by turning the guide into a proper position and holding the pencil on end. with the guide 9 downwardly the sleeves carrying the lead will drop by gravitation through the guide so that the lead will protrude outwardly of the end 6 of the pencil.

The tapered end 6 of the pencil is threaded for threadedly receiving a cap 19, which is also tapered complemental to the tapered Walls of the end 6. The walls of the end 6 are of relatively thin material and accordwindow 20, the portion of the plug adjacent I the window is provided with an inscription sheet 21- which is wrap ed about the plug and provided with suita le indicia 22 to indicate the various colors of the lead carried within the magazine 14.

Accordingly by placing the magazine in the barrel in a predetermined manner to coincide with the arrangement of the color indentifying indicia on the plug and by the proper manipulation of the plug the desired colored lead will be brought into registery with the channel 18 for feeding into the writing end of the pencil.

In the outer end of the bore 12 of the plug is carried a ram rod 23 which ma be utilized for forcing the lead 17 a suita le distance out of the sleeve 16 as the same is used.

It will be apparent that in order to eject the lead a desired distance that the ram rod and sleeve must be removed from the barrel of the pencil. I

It is obvious that my invention is susceptible to various changes and modifications in construction without departing from the spirit of the invention or the scope of the appended claims, and I accordingly claim all such forms of the device to which I am entitled. I

Having thus described my invention, what I claim as new is:

1. A pencil comprising a barrel, a rotatable plug at one end, a rotatable clutch lead guide at its opposite end having an offset feed channel leading from said opposite end to one edge of the inward end, a rod connecting the plug and the guide for rotation as a unit, and a magazine positioned between the plug and the guide clutch and around the rod in the barrel adapted to position a plurality of lead holding tubes, each adapted to be released into the channel of said guide member when any one of said tubes comes into registry with the channel opening at the inner end thereof.

2. A pencil comprising a barrel, a rotatableplug in one end thereof, a rotatable lead guide clutch on the other end, a rod connecting the plug and guide for rotation as a unit,

' the magazine, said block having an irregular conical recess in its other end, and an ofi'set guide rotatably mounted on the opposite end thereof, a rod connecting said guide with said plug for rotation as a unit, an ofi'set channel in the guide communicating with the outer end of the guide and the inner ends thereof, lead gripping fingers carried by the guide, a magazine positioned in the barrel.
