MAGAZINE-F D PENCIL. I

Application filed march 16, 1923. Serial No. 625,557.

To all whom it may concern: I

Be it known that I, AMBROSE FLEMING, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful .Improvements in Magazine-Fed Pencils, of which the following is a specification.

My present invention has reference to improvements in that class of writing devices in which is included a pencil carrying end having the leads so contained and arranged whereby a new lead canbe readily fed into position and forced out of'the holder or casnally of the body.

My present invention is more especially designed for providing certain improved features to that type of pencil holder and lead containing and feeding means disclosed in my patent for pen and pencil holder, issued June 21, 1921, No. 1,382,071.

In my said application, the pencil holder includes a magazine adapted for containing the leads in such annular relation that the said leads are practically automatically and individually fed into position for being moved forward as they are used, by a suitable plunger device, finger operable from the outside of the'holder.

From practical experience with a lead pencil holder constructed along the lines shown in my aforesaid Letters Patent, I

. ing body by suitable means operable inter-" of the nest of leads to bring a new one of the leads in position for being fed out, or broken, by an improper or complete adjustment of the devices that provide for the dropping of a new lead into position for being received by the lead holder and for feeding out the said lead for desired pencil point.

Another feature of my present invention, is embodied in the manner in which the several parts are adapted for cooperative connection, designed for being relatively economically and expeditiously made in quantities and forv being readily assembled for use witliouttlieneed of specially skilled labor.

In its more complete nature, my present invention seeks to provide a simple, compact, easily assembled and positive coactiou of the-parts that constitute the pencil holder projecting the and certain details of construction and ar rangement of such parts, all of which will be hereinafter fully explained, specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view' of a. pencil in which is embodied my invention and,

which illustrates the manner in which it is manipulated for feeding the lead plunger or expelling element forward or backward, as desired.

Figure 2 is a longitudinal section of the magazine end of my improved construction of writing device, taken substantially on the line 22 on Figure 3.

Figures 3 and 4 are cross sections taken on the lines 3 3 and l -4 on Figure 2, looking in the direction of the arrows.

Figure 5 is a side elevation, partly in longitudinal section, of the combined magazine or lead carrier and the lead ejector eontrolling casing hereinafter described.

Figure 6 is a planview of the shiftable closure or gate for regulating the drop of My present invention primarily seeks to "provide certain improvements to the lead holding and positioning devices shown in my other application mentioned, whereby a proper adjustment or setting of the parts must be effected before a new lead can be brought into place from the magazine position, for being engaged by the element that feeds the lead out, as it is-used up; or in other words, provision is made whereby it will be impossible to cause any movement ceiver and holder.

the leads'from the magazine into the lead receiver and holder.

Figure 7 is a planview of the lead re- Brieflystated my present invention comprises an outer casing or shell, one end of which may be, if desired, equipped with. a-

fountain pen, as shown in my patent aforesaid, while the other end is especially adapted to serve as a lead pencil, as is clearly indicatedin Figures 1 and 2 of the drawings.

- The lead pencil carrier, the pencil ejecting elements and the controllin means that oo- .pencil pointis projected and which, in my present form of pencil, constitutes the'turno erate with the said ejecting elements are s own in Figure 2as assembled and in their operative connection within-the casin and referring now more particularly to t e details of construction, 1 designates a casing, in practice similar in size to the conventional fountain pen casing and preferably made of like material.

At one end, the casing 1 is formed with an internal seatradapted for tightly receiving a bushing 2, which latter constitutes a bearing for an elongated sleeve that constitutes a part of the taper cap 3 through which the mg or adjusting member, since by rotating partition ribs 41 that the said member in one way or the other, the lead ejecting and the lead magazine posi: tionin" means are controlled, as will hereinafter. efully. explained;

4 designates a combined leads container or magazine and feed control for moving the pencil plunger or ejecting element 5', and, in ractice,'the said parts are as a single mem-- by a pin 9. The turned up end of the pencil ejecting element or plunger 5 asses radially through the elongated slot 82 in the rear tubular extension 83 of the said receiver or holder, as is clearly shown in Figures 2 and 3 and as presently further explained.

The feed control is in the nature of a tube 6 which is of the same diameter as the tube 40, to one end of which it is fixedlyjoined by a washer which dividesthe leads magaz ne and the feed control and which also serves as a bearing and, stop device for the rotary gate or closure device 12 that holds the several leads in the magazine pocket and which is shown in detail in Figure 6.

The feed control tube 6 has an internal screw 61 of very slow. pitch that extends lengthwise thereof with which the upturned end 50 of the ejector'5 engages, the engagement thereof being such that, asthe tube 6, together with the tube 40 is turned in either direction, in the manner presently explained,

the ejector 5 is moved forwardly for feeding out the lead ahead of it, or for being returned to its rearmost position, when it is desired in a desired condition ready, at preto drop another lead into the receiver or holder, it being understood that as the tubes 40 and 6 are turned, rotation is imparted to the cut off or gate or closure device 12, the rotative movement of which, it should be here stated, is relatively very slow as compared with the rotation of the tubes-4 and 6, the reason for which will be presently fully explained. I

14 designates a sleeve that is tightly held within the casing 1 and which constitutes an inner bearing for the tubular member 6.

To prevent the closure device 12'from movin outwardly, in the'direction of its length, it lias a shouldered part 12 which engages the washer 60, as is clearly shown in Figurev 2, by reference to which and to Figures 4 and 5 it will be observed that the magazine tube 4'has diametrically oppositely disposed projecting nibs 44 thatfit into the elongated slots 31 in the sleeve 30 of the finger operated or turning cap 3, through which connec-, tion rotary movement isimparted to the tubular member 4, as the cap member turned, i

as indicated in Figure 1.

The slot 16 in the closure device 12, through which the member 50 of the lead ejector passes, extends in spirah direction the'full length of thetubular extension=12", so that a continued .feeding' of the ejector to the limit'of its movement, either forwardly or backwardly, effects only one-fourthof a revolutiori of the closure device, as is best understood by referring to Figure 4, from which it will also be seen that a relatively quick turn is always imparted to the sleeve 30, asthemember 3 is turned and the mag azine of leads are constantly turned so, that,- at practicallyall times, one of the lead car- ,ryingpockets is in radial positiogn above the lead receiver 8, theiratio of movement of the parts, as shown in the drawing, being such that during the feed of the ejector backward, its full limit, the magazine will have made many complete revolutions, thereby passing all of the lead holding pockets in line with the receiver 8 and since the closure or cut off device makes but a one-fourth of a revolution during'the complete backward or forward movement of'the ejector 5, it follows that when 'the'plunger or ejector 5 is fed back to the limit of itsmovement which is effected by a stop pin 17 a passage is provided for dropping the. uppermost one of the leads shown in Figure 4 into the receiver in proper'position for being fed out by the ejector 5- as reverse rotation is applied to the cap 3 and to insure a proper feed of the forward end of the lead, the re- From the foregoing description taken in connection with the drawings, it is believed that the complete construction, the manner of its use and the advantages of my present form of writing device will be readily apparent to those skilled in the art to which my invention irelates.

The construction of the parts is coinparatively simple and the several parts are adapted for being readily and economically manufactured and easily assembled for use.

In my present invention, the user must first bring the parts into a predetermined adjustment before it will be possible to feed another lead into the receiver in position for being engaged by the ejector element, which is done by simply tru'ning the cap in reverse direction until it stops, at which time the closure device will have completed its onefourth revolution and opened the passage way through which a lead may be dropped,

' its full length, into the receiver 8 and, after it has thus dropped into the receiver, it may be readily advanced through the cap end 3 to project the desired pencil point by forward or clockwise rotation of the cap lVhat I claim is: Y
