EDWARD SAADI, F BROOKLYN, NEW' YORK.
Applicationy led March 26, 1924. Serial No. 702,034.
To all lwhom z't may concern:
Be it known that I, EDWARD SAADT, citizen the barrel whereby the lead is moved to an operative position when the pencil casing is asped bythe person using the same.
A still'furtler object of the invention is to provide a'pencil of the above mentioned character, wherein means is associated with the barrel and the forward end of the casing for feeding the lead outwardly from the barrel as the same is used.
A. still further object of the invention is to provide a pencil ofthe above mentioned character, wherein means is providedV for returning the barrel to its normal retracted 'position when the pencil casing is released from the hand of the person using the same. A still further object of the invention is to provide a pencil of the above mentioned character, which is simple in construction,
is designated. j
Other objects and advantagesof this invention will become apparent during the course of the-following description.
-In the accompanying drawings forming a part-of this specification and in which like .numerals designate like parts throughout thesame,
Figure 1 is a sectional view through the lowei portion of the pencil With'parts shown in side elevation,
Figure 2 isa fragmentary sectional View ofthe lower ortion of the pencil with parts de elevation,k the barrel being shown in an extended position,
Figure 3 is an enlar ed fragmentary sectional view of the penei Alead feeding means,
- Figure 4 is a transverse section taken apr proximately on line 4-4 of Figure 1,
Figure 5 is a transverse section taken ap-f, s
'the casing 1, and through the stationary and 11o proximately on line 5--5 lof Figure 1,
Figure 6 is a transverse section taken ap' proximately on line 6--6 of Figure 1,
. 4Figure 7 is a fragmentary detail perspective View of the barrel head, and
- Figure 8 is a transverse section taken approximately online 8 8 of Figure 3.
In the drawings wherein for the purpose of illustration isl shown the preferred em-A bodiment of my invention, the numeral 1 designates the casing of my pencil and the same is substantially cylindrical in cross section as is clearly shown in the drawings. The forward end of the casing 1 is open and is internally threaded as is shown at 2 in the drawings. The casing 1 is further provided Wi'th a partition 3 whereby an upper compartment 4 and a lower compartment 5 are respectively formed. Adapted to be placed in the compartment 4 are the extra leads 6. For the purpose of preventing the accidental displacement of the leads from within the compartment 4 I provide the upper end of the casing 1 with a removable closure 7.
Adapted to be supported in the lower end of the casing 1 and threaded into engagement with'the threaded portion 2 thereof is the section 8. The lower or opposite end of the section 8 is provided with an annular groove4 9 and the purpose of this arrangement will be presently described. Cooperating with the stationary section 8 .is the rotatable section and the same has its upper end provided with an inwardly extending annular bead llfo'r .cooperation with the 90 nular flange 14. Also formed integrally on the inner wall of the-rotatable section 10 100 adjacent the lower edge of the stationary section 8 is the spirally arranged annular flange or ring member 15 the samev being split 'so that the respective ends thereof will be spaced apart in the-manner shownat 16-in -105 Figure 8 of the drawings. The purpose of this construction will also be hereinafter" more fully described. y
lSlidablysupported in the lowerlendl of lrotatable sections 8 and 10 respectively is the barrel 17 in'which is adapted to be supported a pencil lead in the manner clearly shown in the drawings. The barrel 17 l is provided with the longitudinally extending slot 18. The upper end of the barrel 17 Supports thereon the head section 19 and the same is provided with the inclined face 20. i The head section 19 is provided for the purposes of forcing the barrel 17 outwardly from the lower end of the rotatable section 10 when the pencil is in use. Normally the barrel 17 is held in a retracted position so that the lower end thereof will be normally disposed within the tip 12 of the rotatable section 10 and for the purpose of holding the same in this position, I provide the barrel 17 with the collar 21, the same being secured thereto in any suitable manner and supported on the barrel so as to be disposed within the upper portion of the stationary section 8. A. suitable coil spring such as is shown at 22 encircles the barrel 17 and is disposed between' the collar 21 and the annular flange 14 and has its ends secured carries thereon the plunger 25. "The plunly ger 25 extends through a suitable opening 26 provided in the side of the casing. in the lower compartment 5 and the inner end of the plunger is provided withv an inclined face 27 for cooperation with the inclined iface 20 of the head section .19. Zhen the person lusing the pencil desires to `projectthe barrel and the lead carried thereby, a spring 23 is pushed inwardly against the casing so that the plunger- 25 will have its inclined face 27 riding on the inclined face 20 of thesection 19 land thus cause the downward vsliding movementv of the barrel 17 through the flange 14 and spiral ring 15 in the stationary and rotatable sections re;- spectlvely so that the vlowerend of the bar rel will project beyond the lower end of the y rotatable section of the pencil in the man.
ner clearlv shown in Figure ings. This operation causesA a downward `movement of the collar 21 so as to result in Vhen' the compression ofthe spring 22h the person releases the spring 23, t plun ger 25 `will simultaneously return to its norfv `mal position and the coil spring 22 'will `cause thebarrel vand head section carried whereby the lower end of the barrel ofthe drawthereby to be returned to their`normal positions whereby the lower end of the barrel will be disposed withinthe tip 12.
For the purpose of feeding the lead 6 which is supported in the lower end of the barrel 17 outwardly therefrom so that a suliicient amount of lead may extend from the barrel for use for an indefinite period, a follower 28 is disposed in the barrel 17 on top of the lead in the manner shown in Figures 1 and 3 of the drawings. The fol* lower 28 is provided with laterally extend ing teeth 29 which are arranged inl spaced relation and the teeth extend through the 'slot 18 in such a manner as to'permit the spiral ring 15 carried .by the rotatable section 10 to engage the same. When the rotatable shell 10 is actuated, the turning of the same will also cause the operation of the spiral ring 15 and the spiral ring 15 is in engagement with the teeth 29, the same will cause the follower to force the lead outwardly through the lower end of the bar` rel thus permitting all of the lead to be used and eliminating any loss thereof. The
provision o-f the groove 9 and the'coacting bead 11 permits the adjustment or rotation of the section 10 on the section 8 whereby the lead 6 may be fed outwardly from the barrel.
It will thus be seen from the foregoing description, Lthat a lead pencil has been prol,
vided which is Very simple in construction, inexpensive, strongl and durable, the parts being so arranged as to permit the same to be easily and readily disassembled whenever necessary, and the barrel carrying'the lead will normally be held in a retracted position, thus preventing the lead which extends beyond the barrel from being broken oft' accidentally when the pencil is not in use. The simplicity in which my invention operates enables the same to be at all times easily and quickly actuated when it is desired touse the pencil and when the pencil is not lin use the parts will automaticallyreturn to their, normal'inoperative positions. A
'While l have shown the preferred em bodiment of yinventionLit is to be understood tha various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit, ofthe inventionV and the scope of the ap-` l pended claims.
