G. A. LUNDMARK COMBINED FOUNTAIN PEN AND LEAD PENCIL Filed March 2. 1922 y Patented Jan. 8, 1924.
GUSTAV A. LUN'DMARK, OF CHICAGO, ILLINOIS.
. COMBINED FOUNTAIN PEN AND LEAD PENCIL.
Application led March 2, 1922. Serial No. 540,397.
To all whom z't may cof/wem.'
Be it known that I, GUsTAv A. LUND- MARK, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented c certain new and useful Improvements in a Combined Fountain Pen and Lead Pencil; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of refer-A ence marked thereon, which form a part of this specification.
This invention relates to a combined fountain pen and lead pencil, and itis an object of this invention to generally improve the structure thereof and to provide a novel form of filler and lead holder.
With these and other objects in view, which will become apparent in the following description and disclosures in the drawings, this invention comprises the novel mechanisms and combinations hereinafter de?v scribed and more particularly pointed out in the appended claim.
In the accompanying drawings, which illustrate a preferred embodiment of this invention, and in which similar reference numerals refer to similar features in the diderent views:
Fi ure 1 is an elevational view of my com- `bine fountain pen and pencil.
Figure 2 is a central longitudinal section of the same upon an enlarged scale.
Figure `3 is a fragmentary longitudinal sectional view upon an enlarged scale.
Figure 4 is an end elevation of a portion of the hood taken substantially upon the1 line 4-4 of Figure 2 upon an enlarged sca e.
Figure 5 is a section upon the line 5-5 of Fi re 2 upon an enlarged scale.
igure 6 is a part sectional and part elevational view of the lead holding point.
As shown on the drawings:
In referring now to the drawings, which illustrate one embodiment of this invention, the numeral 1 represents a hollow cylindrical tube, in one end of which a pen point 2 is secured in any well known. way. A hollow cylindrical member 3 having a reduced screw threaded shank is screw threaded in the other end of the tube 1. The interior wall of the member 3 is threaded and a lead holder d is secured in the outer end thereof. A piece of lead 5 projects from. said holder and may be advanced outwardly by means of a plunger 6 located in the bore of the lead holder which is provided with a slot to accommodate the ouwardly projecting end 7 of the plunger which engages the interior threads of the member 3, and is advanced or retracted by relative rotation of the member 3 with respect' to the member 4. The inner end of the lead holder 4 extends through the end of the member 3 and is provided with a nut or the like for holding the same within the member 3.
The space between the pen and member 3 constitutes the ink chamber in which a resilient or rubber tube 8 closed at its upper end is located. A resilient U-shaped metal 4short wire 11 is swivelled to the end of the wire 10 and extends through an aperture in the wall of the tube 1, the outer end thereof being provided with an operating handle or button 12 normally seated in a recess. It is apparent that the yoke members 9 are rendered flexible by bein pivoted together and that the wires 10 an 11 constitute a flexible connection thereto which may be pulled outwardly to draw the oke members together and compress the resi ient U-shaped member, as shown in dotted lines in Figure 3, to collapse the rubber tube 8 and diminish the air therein, so that upon release of the handle 12, the ink will be drawn up in the ink chamber if the end thereof has been inserted in a supply of ink before such release, according to the well-known vacuum lift principle.
A novel form ofl hood designed to slidingly telescope either over the pen or pencil end of the article is provided. This hood consists of a pair of separable sections 13 and 14 which 'may be united in various ways. In the present instance, they are shown'in screw threaded relation, and one of said sections, in the present instance the section 14e, is provided with a plurality of cavities or bores 15 in which pieces of lead are adap to be stored. When a new piece of lead is desi, it is only 1: w to uncouple the 4sections ofthe hood and remove @3 rneveDeee au piece of )leed from its cavity, es is obvioiis.
From tbe foregoing description, it is obvious that )i have provided a novel form of seit-@Ming fountain ri that is provided with e lead peiieii, ein in which tire bood Jfor the peri serves as e container for extra Reed pointe.
il am aware that numerous detailis of construction may be varied through a Wide ronge without departing from the principles oiE this invention, and 1I tbereforedo riot purpose limiting the partent granted other- Wise than necessitated by the prior ort.
il claim as my invention:
