PENCIL.

Application filed September l, 1920. Sera1 No. 407,462. i i

To all wwmz't 'may concern.'

Be it known that I, Hormon H. llVnLcrna citizen of the UnitedStates, and resident of Chicago, in the countyl of Cook and State 5 of Illinois, have invented a Certain new and `useful Improvement in Pencils, Of which the'following is a'full, clear, concise, and exact description, reference being had to the 'accompanying drawings, forming a part of this specification. y Y

My invention relates' to improvements in pencils, and is especially concerned with improvements in that type of pencil which comprises a barrel made of metal orl other l5 suitable material having a passageway therein for, receiving and holding leads,`and suitable means for extruding the end of the lead through one end of the barrel, so that it can be fused for writing. ,p

y The objects of my invention are`l` e First, tok provide a pencil of this character comprising novel means for extruding or feeding the lead from the end of the pencil, comprising a feed-bar, a Aportion of which is in registry with anopen'inginthe side Of the pencil barrel therebyv permitting 4 it to be grasped by the fingersv and moved in a direction to extrude the lead from 'the barrel, and f Second, to provide a` `pencil of thel char-- acterdescribed, which is simple in construction, economical to manufacture, and easy to operate.

These and other Objects will definitely appear as 'the description progresses, reference` being had to the accompanying drawings, in whichv y Figure 1 is a central longitudinal section, through my improved pencil.

Figure 2 isa side elevation thereof, with portions broken away, this view being taken at right angles to that in Figure 1.. Y

Figure 3 is an enlarged side elevation with parts of the pencil brokenaway.

Ll5 Figure 4 is a transverse section on an enlarged scale on line 4-11 of Figure 1, and Figure 5 is a perspective view of the feed bar and associated parts of my pencil.

vThroughout the several views, similar reference characters will be used for refer,-

ring to similar parts.

10, of metal or other suitable material, more or less permanent in character, one end of which is tapered as shown at 11, and probar 20,'-the free ends of these spring-s being in frictional Contact with the inner wall of videdV with a' lead receiving andvguiding tube 12, into the outer end of which-the hollow tip 13 is secured, thistip being provided with a shoulder 14 bearing against the end.'l of the barrel in such a manner that when the tip 13 is completelythreaded into the end of tube 12, bothv of these ymembers' are rigidly clamped to the end of the barrel.` A cup 15 isk soldered orl otherwise secured in the opposite end of the barrel at suchadise tance from the end thereof as to provide a suitablemagazine for the reception of leads 16, the outer end of the magazinefbeing' closed by a cap 17 orin anyotheridesired,y y' ,.70

manner. e The barrel 10 is provided intermediate Vits ends with two diametrically'oppositeslots 18. The incisions forming the'ends of these slots are continued -a short distance past each j sidey of the slot to form tongues 19'Jwhich` are bent 'inwardly slightly to form spaced y guides for receiving and guiding the feed bar-20, theopposite edges of which will then extend through the slots 1S, thus permitting `the user to grasp these 'edges tojmove the the pencil barrel.

Itis believed that the operation of my improved pencil will be apparent from the above description. In use, it is merely necf essary to insert a lead through the tip 13 and into the tube 12, and wheneverfit is".r desired toeXtrude the lead, the user grasps the edges of the feed bar projecting through Y the slots 18, and moves the feed bar slightly towardrthe end of the barrel' carrying the tip 13. rIhe friction of the lead in thetip y13, plus the application of the springs 22, i

bearing againstthe walls of the barrel, will '105 be sufficient to hold the lead in any of itsj y improved pencil comprisesa barrelV adjusted positions.

While I have described the details of conn struction of the preferred' embodiment of my improvedpencil, it isuto be clearly un- 1.10l

derstood that my invention isnot limited to these details, but is capable of other adaptations and modifications Within the scope of the appended claims.

Having thus described my invention, what I claim is:

l. A pencil comprising a barrel having a lead receiving tube and tip at one end, the said barrel having diainetrically disposed longitudinallylv extendinga slots, formed in the sides thereof, the edges of said slots beingturned inwardly to form Aguides` a feed bar slidably mounted in said barrel, and having` its edges projectingv through said slots between said 2(guides, the said feed bar having a push rod secured thereto slidable in said lead tube, and abutting' the end of a lead in said lead tube, and a'spring secured to said feed bar and having frictional engagement with the inner Walls of said barrel.

2. A pencil comprising' a barrel having a lead receiving tube at one end, said barrel having a pair of diametrically opposed flats and a slot extending longitudinall;7 of said barrel in each of said fiets, a feed bar slidably mounted in said barrel and havingy a lateral edge projecting through nach said slot and guided by the edges of said slots,

Vthe said lateral edges of said bar being' supported by the inner surfaces of said barrel, and a push rod extending from said bar, the free end of said rod being slidable Within said lead receiving tube, and adapted to abut the inner end of a lead, and means for holding said feed bar relatively to said barrel.

3. A pencil comprising a barrel having a lead receiving tube at one end, a feed bar slidable in said barrel, said bar by means of its edges being supported by the inner surfaces of said barrel, means for preventing the rotation ofl said bar relatively to said barrel, a slot in said barrel, said barrel being indented adjacent the edges of said slot to present the said edges of said feed bar in manually manipulatable position, a push rod extending from said bar, one end of said rod being); slidable within said lead receiving); tube, and abutting the inner end of a lead, and means Within said barrel for adjustably holdingr said feed bar relatively to said barrel.

et. A pencil eomnrisii'ip; in combination a barrel, a lead receiving tube in one end of said barrel, a feed bar reciprocable in said barrel, a feed rod secured to said bar vand, reciprocable in said tube to feed a lead therein, said feed bar having a knurled lateral edge adjacent the periphery of said barrel, an opening in said barrel, means for keeping said knurled edge in registry withv` said slot, the margins of said slot beingy indented to allow an operators finger to engage said knurled edge to adjust said feed rod` and means Within said barrel to hold said feed bar in its adjusted position relative to said barrel.

ln Witness whereof`I hereunto subscribe my name this 26th day of August. 1920. HOB-ACE H. WELCH. Witnesses:

EARL R. PIERCE, ARTHUR W. CARLSON.
