Patented May 28, 1935 PATENT orrlcs' COMBINATION WRITING Giuseppe Donate,

Philadelphia, Pa.

Application February a, 1934, Serial x. mm

10 Claims. (01420-0) This invmtion relates to combination pencil and fountain and for an object to provide an instrument of the type wherein either of. the instrumentalities may be projected 'into 5 writing positionand that while the instrument is heldin writing grasp in the hand.

. A further object of .the invention is to provide in the instrument of the type a pen movable longitudinally within a barrel in such .manner that its extreme point projectsslightly through a perforation in a cap at the endjof the barrel, the major part of the pen remaining within the structure. t

T A further object of the invention ,is'to provide .an instrument of the type having an extremity conoidal in shape through the apex of which may be projected electively a pen or a pencil as the writer progresses in its use which are the basic features of my invention.

A further object of the invention is to provide an instrument of the type having a barrel whereinis mounted slidably a pen carrying an ink res-' ervoir therewith which said pen is projected to writing position with its point only extending slightly beyond the conoidal end of the barrel structure with means for projecting the lead of a pencil also beyond the point of the conoidal structure.

A further object of the invention is to provide within a single instrument a plurality of pens either of which may be projected to writing position independently of the other and a plurality of pencils the lead of which may be independently projected to writing position which is a generic feature of my invention.

A further object of the invention is to provide a pen structure including a pencil having a cap thereon remaining fixed upon the structure during the operation of both pen and pencil which extend through said cap into operative position, eliminating the use of a. removable cap as customarily found in all such structures.

A further object of the invention is to provide in an instrument of the type a barrel having a cap formed as a conoid having a small perforation in its apex with a structure within the barrel carrying a pen the point of which is properly contoured to extend through the perforation in the apex of the conoid with means at the opposite end of the barrel for actuating the pen and its associated structure.

The invention further comprises a body having one or more barrelsas a part of such structure within which barrel or barrels are located slidable members each carrying a pen and an ink reservoir, the barrel being provided with a conoidal cap, perforated at or adjacent to its apex providing for the passage therethrough of the pen or pens to extend merely to such an extent as to be in writing poation, the major part 5 of the pen being still retained within the conoidal cap with one ormore tubes associated with the barrel or' barrels, each of said tubes being provided with a structure adapted to retain the lead of a pencil and means for movingthe structure longitudinally of the barrel to project the lead ofthe pencil through a perforation ator adjacent to the apex of the conoidal cap and into writing position whether the pen be in writing position or not.

At its opposite end the barrel is provided with a sleeve 32 and a cap 33 mounted thereon which provides space which may be employed for a purposedesired; as for instance for containing the extra leads 34.

The term lead as employed in this specifi-;

cation and claims is' intended to convey such rigid writing medium as is ordinarily found, in lead pencils or the like irrespective of the color or actual material from which it is constructed.

Within the barrel to a block as is. mounted to slide and for sliding the block a wire 35 is provided having substantially parallel legs joined by a cross bar 31. Upon this cross bar 311a disk 38 carried by the sleeve is provided so that as the sleeve 32 is screwed downwardly upon the bar-'- rel the disk 38'bears upon the cross bar 31, de-

omitted between the member 49 and of the opening 41.

pressing the legs of the wire 35.

To resist such movement-a spring 39 is employed bearing at its upper endagainst a disk 40 and at its lower end against a disk 4| seated uponan annular shoulder 42 in the barrel.

when, therefore, thesQeve 32 is screwed downwardly from the position shown at Figure 2'to the position shown at Figure 3, the block 35 has moved downwardly as shown in those figures.

To insure the proper function of the wire 35 to move the block the ends of the wire are bent inwardly to form hooks 43 hooking into the block.

This block 35 is provided with a reduced neck 44, with a passage 45 therethrough and a collapsible andresilient bag 46 mounted upon the reduced part.

The block is also provided with an axial opening 41 in which is mounted a sleeve 48. Within this sleeve 43, which may be omitted if desired, the pen and feeding organization are inserted. This comprises a member 49, (see Figure 4) having a passage 50 which is eferably filled with an absorbent material s pported in any approved marmer as by the pin 52. This absorbent material is in communication with the passge 45 leading from the ink reservoir 46 so that the ink contained within the reservoir is absorbed in the absorbent material 5|. Member 49 is provided with a passage 53 which is also in communication with the ink supply with an offset or lateral pas-..

sage 54 which communicates from the absorbent material to the passage 53. 3

After this has been inserted into the block 35, the pen 55 of any usual and well known type may be insertedbetween the member 49 and the sleeve 43 when employed, or if the sleeve 48 is the walls Instead of making the member 49 simple as shown at Figure 4, a modification as shown at Associated also with the pen structure is a pencil structure. .This comprises a pusher wire 58 having a sleeve 59 of proper contour to receive and retain a lead 80. For moving the lead to operative position a slot Si is provided in the side of the barrel and the wire is provided with an angular part 30' which extends to or beyond the surface of the barrel as indicated at Figures 1 and ,3. The movement of the wire in the direction indicated by the row in Figure 3 will move the lead 50 so that it will be projected through the perforation 52 to the position shown at Figure 1.

For filling the reservoir 46 aperforation 63 is provided through the barrel through which any slender instrument may be inserted. A spring 64 is supported by means of a resilient ring 65 (see Figure 21) and extends downwardly along the side of the bag 46. This spring is provided with the return bend 55 whereby a part 66 is provided which will not follow the curvature of the spring 64 when the instrument is inserted as indicated in dotted lines at Figure 3, but will compress the bagas also indicated in dotted lines at that fig-' ure, The resiliency of the bag will, of course, tend to expand the bag to induct ink within the bag through the structure in the usual well known manner, the cap 3| being previously preferably removed for that purpose.

In the type shown at Figures 9 to 11 inclusive, two barrels 31 and 68 are provided, eachsimilarlf accommodating a bag 69 and 10 which communicate with the pen through substantially the same structure as shown at Figures 2 and 3. Instead, however, of moving this pen structure by means of a threaded sleeve the cap H is fixed relative to the structure of the barrels 61 and 68, slidable independently relative thereto and to the conoidal cap I2 so that either the pen 13 or I4 may be electivelyprojected by simply pushing longitudinallyupon the barrel 61 or 68 which carries the pen which it is desired to use. It is, of course, contemplated that inkof diiferent colors shall be employed in the two bags 59 and I0, and that therefore the projected pen will write the color of ink carried in that organization. It is obvious that as the structure shown at Figures 9 to 11 inclusive is held in the hand in writing position either of the barrels 51 or 58 may be moved to writing position, thereby changing from one color to another without changing the position of the pen structure in the end, and that substantially instantaneously.

The conoidal cap I2 is made slidable upon the barrels 61 and 68 as indicated by space at Figure 10. When it is desired that both pens shall project simultaneously the cap I2 is moved to close the space 15, whereupon both pens have their points extended beyond the conoidal cap may be closed by any type of block II. It is contemplated that this block "shall be a type to serve as an eraser and is brought into use by the removal of the cap II.

The bags and It are nlled by the use of the same type of filling device shown at Figure 21, comprising, the ring I, spring 84 and its associated parts. i

In the angles provided by the associated barrels l1 and I smaller barrels II and II are provided. These barrels II and II are provided with slots .0 and 8| through which extend respectively the members it and 88. These members I! and It are associated with wires It and." which slide longitudinally within the barrels I! and It and are each provided with a sleeve II which receives and retains a lead .1.

Whiletwo of these barrels l8 and II with their lead and accompanying mechanisms have been shown it is obvious that either or both may'be omitted. At Figure 16 a single perforation I! is shown to accommodate one lead the other being omitted, while at Figure 17 both leads are indicated as omitted openings 8| and ll being provided to accommodate both of the pen points. Joining these openings ll and II orotherwise communicating therewith is a vent OI which relieves internal suction. i

To provide for properly sliding the cap 12 or the barrels 01 or 68 relative to the cap 12, the cap is provided with knurled portions 0| shown more particularly at Figure 14.

To, provide for maintaining the two barrels in operative relation to each other while being moved independently one is provided with a channel chamber 82 and the other with a cooperating part 93 as shown at Figure 13. These members 92 and 93 extend from the upper end of the pen longitudinally to about the point indicated at it in Figure 11. By stopping at this point a certain amount of resiliency is provided between the barrels 61 and I whereby the barrels tend to spread when the conoidal cap 12 is pushed forward in disengaging use of pens and therefore exert a tension upon the cap to maintain the cap in position when the cap is so located.

As an alternative a dove-tailed connection 03 is shown at Figure 19. As shown at Figure 13 the barrels 81, II, II and I! each stand independently and in full sight of the user. In the type shown at Figure 19, however, all are formed within the moulded or otherwise produced structure whereby a device is produced which is substantially elliptical in transverse section all of the barrels being contained within the ellipse.

Figure 18 is in view partly in side elevation and partly broken away of the type shown intransverse section at Figure 19 and discloses the configuration oi the barrels in that type.

In operation, the single type as shown at Figures 1 to 3 inclusive is employed by manipulating the cap 33 to actuate the sleeve 32 and thereby depress the spring of the pen structure forcing the point only of the pen through the perforation 51 as shown at Figure 3. The advantage thus attained is that substantially the entire pen is covered and the fingers of the user do not become smeared with ink as in the use of ordinary pens. Also when the pen is retracted to the position shown at Figure 2 it is completely enclosed and it is not necessary to remove and replace a cap at each use of the pen, the pen being sumciently protected and covered when withdrawn within the cap 3|, without any additional or auxiliary cap. The pen thus extended'may be employed in the usual manner and whenever it is found desirable the pencil may be conveniently manipulated with the structure still in writing position so that change may be instantly made of the pen through the conoidal cap in the same position as described in regard to the use of the simpler type shown at Figure 3. Both of such pens may be simultaneously extended, when so desired, and either brought into use simply by rotating the structure in the ringers. The same 15 protection is afforded-by the cap 12 as described in regard to the copy 3| oi the singlebarrel type. In the structureshown at Figures 9 toll. in-- elusive where two pencils are likewise disclosed, it

is contemplated that leads within the meaning 20 above described of different colors shall likewise be employed and either may, therefore, be usedselectively or both may be advanced simultaneously and by mere rotation may be brought into use. These may be one or both extended, while I one or both of the pens are also extended so that with the device as shown at these figures, a complete writing instrument capable of writing in two colors of ink and twocolors of pencil, with no manipulation whatsoever, is afforded.
