PENCIL.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed. January 17, 1921. Serial No. 437,759.

To all whom it may concern:

. in the county of Bristol and State of Massachu'setts, have invented new and useful Illirovements in aPenc-il, of which the folowing is a specification.

This invention relates to certain new and useful improvements in a pencil, and it has for an object to so simplify the construction as to facilitate and expedite the assemblage ofthe constituent parts thereof during the process of manufacture.

The invention also will be found'to reside in thesalient features of construction and the arrangements and combinations of parts hereinafter specifically described and succinctly claimed, reference being made to the accompanying drawing wherein.

In the drawing:

Figure 1 is a longitudinalsectional view through the improved pencil showing portions of the interior construction in elevation; v

Fig. 2 isa detail elevation of the end cap thereof;

Fig. 3 is a similar view of the eraser- Fig. 5 is a similar view of the lead tube.

Referring more in particular tothe drawing, the pencil comprises an outer shell or case-1 and an inner tube 2, the latter having its outer end 3 enlarged, for a rotatable fit in the outer end of the case, and also split, as at 4, to provide a resilient extension from the case to frictionally receive the eraser-holder 5 and to be received by the, cap 6. In this connection, it may be noted .that the cap has an opening inits top through which the eraser 7 or the raised head 8 may project, the latter being suitablv finished or set with a *ewel.

The inner end of 't e tube 2 is formed with an abutment 9 against which the washer 10 is disposed, having frictional fit on the tube, and below this washer is a secon'd washer 11 frietionally engaged in the case but in whiehthe tube is freely rotatable.

On the tube below the washer 11 is a third washer 12 also frictionally held on the tube and projecting beyond the same to snugly receive a disk 13 having an axial opening in solder.

which the upper end of the lead guiding tube it IS freely supported. The lower end of the lead guiding tube terminates in leadclamping jaws 15 designed to frictionally hold the lead against retrograde movement, the same coc'iperating with the tapering lower end of the case 1. The lower end por-- tion of the lead guide tube is forced through a disk or washer 16 having frictional-fit in the lower end of the case and against an abutment formed by the tapered end of the casethrough which the lead projects, where'- by the tube is-securely held against rotative movement. The )in or plungerl7 for advancing the lead in the tube 14 has a laterally projecting lug 18 which moves in the slot 19 of said tube under the influence of the coiled, thread-forming member 20, the latter having its upper end seated in a sec- 0nd opening or recess in the disk 13 whereby when the inner tube 2 is turned with the fingers the coiled member 20 willalso revolve about the lead tube and exert a camming effect on the lug 1' A retaining clip 21 is also secured in the case by inserting one end through a slot in the wall thereof to lie between the case and the inner tube where it may be fixed as by In assembling, the washer or disk 16 is of the casejl and then the guide tube 14 is forced through the said disk to its proper position, as depicted in Fig. 1.' Following this, the lead-advancing follower or plunger 17'is dropped in the tube 14 with its lug 18 projecting outwardly through the slot 19, and the coil 20 is then inserted within the ner tube.

Thus, the assembling or the pencll is completed in a very expeditious and easy man-' ner without expensive machine operations. The disk 16 serves to support and sustain the lead tube in proper spaced relation with case and rotuted to bring the plunger into the case and concentric therewith,.the disk 13 cooperating with the former disk in supporting the inner end of said tube. a The Washer 11 provides a simply constructed retaining means for the operating inner tube, permitting free rotation thereofbut preventing lengthwise movement by reason of the abutting washers l0 and 12 on oppositesides thereof. The enlarged end 3 has a rotatable fit in the outer end of the case to provide a rigid structure thereat. By turning the cap, which has frictional connection with the inner tube, the coil member20 is revolved to correspondingly shift the plunger 17 in the lead tube. This provides an exceedingly simple feed for the lead with few parts to repair or get out of order.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a pencil, a case having a tapered end, a disk frictionally engaged within the ease and with the tapered end so as to be held by the latter against sliding. an inner tube in the ease having an enlarged outer end rotatably engaged with the case and having a reduced inner end forming an abutment, a washer engaging the abutment and frictionally fitted over the reduced end of the tube, a second washer frictionally fitted in the case and rotatably receiving the reduced end of the tube, a third washer frictionally fitted on the tube and projecting beyond same, an apertured disk engaged within the third washer and with the terminal of the reduced end of the tube, a lead guiding tube received at its up er end in the disk aperture. and lead feet ing means including a thread member engaged at one end with the first named disk and at its 0p-' posite end being received in an opening provided therefor in the second named disk.

A pencil comprising a case, a lead guiding tube secured therein againstrotation and provided with a lengthwise slot, 8.

lead-advancing plungerarranged within the tube and provided with a lateral lug operating in the slot, an operating tube rotatable in the case, a pair of relatively spaced collars frictionally fixed on the inner end of the operating tube, a third collar frictionally fixed inside the case between the pair of collars and rotatably receiving the operating tube, and a thread member engaged tube.

3. A pencil comprising a case, a lead guidingtube secured therein against rotation and provided with a lengthwise slot, a

lead-advancing plunger arranged within the tube and provided with a lateral lug operating in the slot, an operating, tube rotatable in the case, a pair of relatively spaced collars fixed on the inner, end

of. the operating tube,a third collar fixed inside the case between the pair of collars and rotatably receiving the operating tube a disk carried by the inner one of the pair 0 collars and formed with an opening reeei'vwith the lug and operable by the operating 55 ing the inner end of the lead tube, and e coiled member rotatable, about the latter :in

nection with the disk.

4. In a.pencil,-a case, a disk-frictionall engagement with the lug and having con secured therein, a lead tube inserted throng Ni circling the tube and receiving the lug be-:

tween its coils and an operating device consiSting of a tube rotatable within thecase and releasably engaged with the, adjacent terminal of the coiled member. i

5.. Ina pencil, a case having an abutment v.85

therein, a disk frietionally fitted inthe case and engaging the abutment, an innertube; in the case rotatabl engaged: therewith "at one end, a washer rictionally fitted inbt he case, means on the inner tube to engage-the washer to limit inward movement ofgthe; inner tube, sa d washer receiving thebinner tube to allow. the latter to rotate, a washer; H

frictionally fitted on the innertube, a disk connected to theflast mentioned washegand 1 lead feeding means including a'thread mem z.

ber engaged with the first nameddislnand, with the second named disk so as to beheld in lace by said disks,

n testimony whereof we have-signed our 5100' names to this specification. in the two subscribing witnesses. p
