MULTIPLE FOUNTAIN PEN.

Application filed March 5, 1921. Serial No. 449,958.

To all whom it may concern.

Be it known that I, LAWRENCE L. Houses, a citizen of the United tates, residing at idishawaka, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Multiple Foum .uiu Pens, of which the following is a specification.

The invention relates to multiple fountain pens and has for its object to provide a device of this character comprising a cylindrical body member having a substantially centrally disposed partition therein thereby forming parallel chambers in the body member, in one of which chambers a longitudinally movable fountain pen is disposed and slidable, and the other chamber forming a reservoir for a non-movable pen which projects from one end of said chamber. Also to provide means whereby the movable pen may be held in retracted position in its chamber or in extended position.

A further object is to providev a multiple fountain pen particularly adapted for book keepers and draftsmen and in other occupations where two colors of ink are neces sary, for instanceblack and red ink.

it further object is to providea screw cap for the rear end of the cylindrical body member which sore Y cap houses filling opening closures in the movable pen and the reservoir of the fixed pen.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a view in elevation of the pen.

Figure 2 is a vertical sectional view taken on line 22 of Figure 1.

Figure 3 is a plan view of the rear end of the pen, showing the same with the cap removed therefrom.

Referrin to the drawings, the numeral 1 designates a cylindrical body member and 2 a partition extending through said body member, which partition is centrally disposed thereby dividing the chamber of the body member 1 into semicircular chambers 3 and at. The chambers 3 and 4 extend substantially the full length of the body memher 1, however the semicircular chamber 3 forms reservoir for the reception of ink I and into which reservoir ink is placed through the apertured upper end 5 which is normally closed by a threadedplug 6. The lower ends of the senilcircular chambers 3 and 1 taper and disposed 1n the lower end of the chamber 3 is a conventional form of fountain pen feeding plug 7 which carries the fountain pen 8. It will be seen that the pen point 8 is a fixed one and the ink most commonly used, for instance black,"is placed in the chamber 3, therefore for ordinary work the bookkeeper or draftsman would use this pen.

Slidably mounted in the semicircular I? k chamber ,4 is a semicircular shaped casing 9 which casing is provided with a chamber 10 forming an ink reservoir, into which ink is placed by removing the plug 11 in the upper end thereof. The lower end of the casing 9 is tapered as. at 12 at substantially the same angle as the lower end of the chamber 4: thereby providing means whereby the cars ing 9 will be limited in its outward movement, said lower end offthe casing 9 being provided with a conventional form of pen point 18, which when-the casing is forced downwardly assumes the position shown in Figure 2 and in which position the lower end of the pen point 13 will project beyond the pen point 8 and be in a position where it can be used for writin or drawing lines. The ink placed within the reservoir 10 is preferably red, however it may be of any color desired. Secured to the casing 9 as at 1 1 is a leaf spring 15 which leaf spring extends upwardly through an elongated slot 16- in the cylindrical body 1 and adjacent its free end is provided with spaced prongs 17, which prongs when the casing 9 is in the position shown in Figure 2 engages apertures 18 in the outer periphery of the cylindrical casing 1 and holds the casing in retracted position as shown in Figure 2. When the prongs 17 are disposed in the apertures 18 the upper end of the casing 9 is flush with the upper end of the cylindrical casing 1 and .is in a position where the plug 11 may be easily removed when the cap 19 is removed, thereby facilitating the filling of the reservoir 10. When the casing 9 is extended after pulling outwardly on the leaf spring 15 by grasping the knob 20 and forcing downwardly on the same, said casing is held in proper extended position and the pen 5 From the above it will be seen that a multiple fountain pen is provided, which is sim ple in construction and one wherein the movable pen comprises a longitudinal movable casing having a reservoir therein and a pen,

which penand reservoir comprise a single unit, thereby obvlatlng leaking which is common in pens of this character and also reducing the parts to a minimum and sim-:

plifying the construction. a

The invention having been set forth what is claimed as new and useful is 1. A multiple fountain pen comprlsmg a casing having longitudinally disposed semicircular chambers therein, a pen point extending from one end of one of said cham bers, the upper end of the chamber having the pen point having a closed filling opening, a longitudinally movable fountain pen casing disposed in the other semicircular chamber, a pen point carried by one ,endof said longitudinal movable casing, a closed filling opening carried by the upperend ofsaid longitudinally movable casing, a leaf spring having one of its ends secured to the longitudinal movable casing, said leaf spring extending upwardly and outwardly through anelongated aperture in the main casing, the free end of said leaf spring being pro vided with prongs, said prongs being adapted to engage aperturesin the outer periphery of the casing for holding the longitudinal movable casing in extended or retracted position.

2. A multiple fountain pen comprising a cylindrical casing having longitudinally disposed chambers therein, a fixed pen-point carried by one of said chambers, a longitudinally movable fountain pen unit slidably mounted inthe'other chamber, means for holding the longitudinally movable fountain pen unit. in retracted or extended position,

The combination with a fountain pen.

having a reservoir within a casing, a pen point at one end of said casing and a closed filling opening at the other end thereof, of an auxiliary casing carried by said-casin said auxiliary casing having a longitudinally movble fountain penunit slidably mounted in a chamber thereof, a filling opening at the upper endof said fountain pen'unit, a pen point at the other end of said fountain pen unit and means for holding said fountain pen unit in extended or retracted position, said means forming means whereby when the fountain pen unit is in retracted position the filling opening thereof will be in the same transverse plane as the filling openingof the main casing.

In testimony whereof I affix m signature.
