rolaim. (c1. 12o-113) iy y Thisinvention relates to certainnew and useful v"improvements"in lettering, drawing, Writing @and lmarking pens, particularly `adapted for use -"in connection lwith sign'writing of a commercial nature.`

The `primary object ofthis invention'is to pro- `videa device of the above mentioned character adapted to allowvthe use-of opaque colors in let* tering a feat which 'has heretofore'been impossible with `p'resent'day lettering pens.

further object 'f this jinventionis to provide apen point 'having' an adjustable feeding device formed of a transparent flexible materialpreferably Celluloid or nitro-cellulose material.

-A still further object of this invention is to fprovide la `pen point formed of Celluloid or the like stamped from 'a sheetof material and bent 2so as to-be yreceived in a tubular holding member. Affurtherobject of rthis invention is to provide ^1a pen point `of `the above Amentioned character l'having a feeding device formed vof the same -ma- Vterial and secured to a metal band adjustably "secured Ito' the tubular holding member whereby Atheffeeding device may be adjusted longitudinally relative `tothe pointer writing portion ofthe pen -point. y

A still further "object of this invention is to provide-a'writinglettering and marking pen point with a writing surface having parallel slits eX- tending inwardly therefrom which assist the feeding action.

A still further object of this invention is to provide a marking and lettering pen point which is extremely flexible and which permits the use of heavy opaque color or liquid as well as the lighter inks and fluids.

A still further object of vthis invention is to provide a marking and lettering pen of the character described having a feeding device adaptedv to be adjusted so close to the writing surface of a pen point that the fluid will flow more freely and heavy so that when the writing fluid is dry the marking thereby made has the appearance of embossed lettering, which is actually raised on the surface of the paper or board upon which the pen is being used.

A still further object of this invention is to provide a combined feeding and agitating nib to perform the function of feeding the ink or writing fluid as well as agitating the same and preventing the hardening and congealing thereof.

Other objects and advantages of the invention will become apparent during the course of the following description, forming a part of this specification and in which,

Figure 8 is atransverse cross-sectional View 80 taken4 on line 8;-8 of 4Figure 2, illustrating the `manner lin which thepen point is fastened to the holder.`

In the drawing, wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughout the same, the reference character 5 will be generally employed to designate a Writing pen handle shown in Figs. 1, 2 and 3 in dotted lines forming a handle for the pen.

On one end of the pen handle 5 is secured a metallic band 6 preferably hexagonal in crosssection to insure a frictional contact upon the end of the pen handle and also to permit a true longiv tudinal movement of the feeding and agitating device. The hexagonal band 6 is split as at 7 toinsure a gripping action upon the end of the pen handle and to also allow for the forward end adjacent the split portion at 8 being return bent for securing the pen point 9 formed of celluloid or a regenerated cellulose material. The pen point 9 may be stamped from sheet material and the rear portion is bent arcuately as at 10 for being retained in the hexagonal holder 6. The m15 forward portion may be more or less pointed as at 1l and may be provided with a transverse flat writing surface l2 having inwardly extending slits 13 for the purpose of assisting the feeding action,

lill) It is to be understood, that the pen point 9 may be of any desired shape, but the best results have been obtained by the shape shown in the vdrawlng.

Movably mounted upon the hexagonal pen point holder 6 is a band 14, preferably of the same configuration in cross-section as the band 6 so that the band 14 may be slid longitudinally thereof for the purpose of adjusting the feeding device.

Formed integral with the band 14 and extending laterally therefrom is a holder for the feeding device comprising a return-bent section 15 terminating in a fiat portion 16 having inturned edges 17 for receiving the inner end of the feeding device 18 as clearly shown in Fig. 4.

The feeding and agitating device extends forwardly from the reduced portion 18 in spaced relation from the writing pen 9 for a portion of its length and then is bent downwardly toward the writing pen for another portion of its length as indicated at 19 so that the free end thereof nearly contacts with the free end of the writing pen 9. As shown in the drawing, the feeding and agitating device is preferably flat and enlarged as at 20 extending downwardly from the central line 21 to the converging line 22 thereby producing between the writing pen 9 and the feeding device a sizeable pocket for receiving the marking or lettering fluid which when in use is fed to the point of the pen 9 and to the slits 13, extending inwardly from the writing surface 12. It will be observed that the pen point 9 is imperforate over its entire area and the writing end 12 thereof is provided with relatively short slits. Also, the feeding device has an intermediate reduced portion enlarged at its outer end as at 2O to provide a reservoir overlying the writing end of the pen point. This arrangement of the pen point and feeding device assists the flow of fluid and draws it toward the writing end of the pen point from the feeding reservoir, but does not allow the fluid to pass through to the underside in excess quantities, rendering it possible to control the flow of the fluid at the point and further operates to prevent blots or pools of the fluid. The pen point remains unweakened by the provision of the relatively short slits in the writing end thereof and longer life is imparted thereto as contrasted with the usual pen point of this character that is provided with holes, slots or other openings.

It has been found in practice that by moving the band 14 relative to the tubular holder 6 so that the free end of the feeding device 19 will be moved toward and away from the writing surface 12 that the amount of ink or marking fluid may be increased or decreased according to the type of lettering which is desired.

It has also been found in practice that due to the transparency of the fluid feeding device and the pen point the user thereof may have a clear vision of the surface upon which he desires to mark or letter thereby enabling him to produce lettering and marking with more accuracy which results in lettering or markings having more ornamental and pleasing characteristics.

I am aware that Celluloid pen points have heretofore been employed, but it is believed that the pleasing effects obtained by the present invention are due to the feeding device in combination with the Celluloid pen point due to the'fact that the feeding device is formed of the same material thereby allowing both the same degree of flexibility and permitting the use of opaque colors.

It is to be understood that the form of the invention herewith shown and described is to be taken as a Vpreferred embodiment of the invention and that various changes in shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claim.

I claimzy In a pen of the character described, a pen handle, a band secured to the handle, said band being longitudinally split and having return bent portions at the forward ends of the split, apen point of flexible transparent material having its inner end within the band and engaged bythe return bent portions of the band to be retained therein, a second band slidable upon the first named band, said second band having a returnbent portion with inturned side edges, and an ink feeding device rhaving oneend slidably received in the return-bent portion of said second band, said feeding device overlying the pen.
