FOUNTAIN-PEN.

Specification of Letters Patent. Patented Sept. 20 192L Application led May 7, 1920. Serial No. 379,560.

To all whom it may concern:

Be it known that I, NORMAN H. A. NELSON, a citizen of the United States, residing at Flint, in the county of Genessee and State ot Michigan, have invented certainnew and useful Improvements in Fountain-Pens, of which the following is a Speciiication.

This invention relates to self-illing fountain pens and has for its object the vproduction of a Simple and efiicient fountain pen wherein two separate compartments are employed for the purpose ot permitting two different colors of ink to be retained in the pen in the separate compartments.

Another object of this invention is the production ot a simple and efficient means for facilitating the filling of the pen after the bulb in either compartment has become empty.

Other objects'and advantages of the presen t invention will appear throughout the following specification and claims.

In the drawing Figure 1 is aside elevation of the pen, and

Fig. 2 is a longitudinal section therethrough. r

.By referring to the drawing,l it will be seen that the pen comprises a body formed of a'piimary section 1 and an auxiliaryvsec-l tion 2. The primary section 1 is provided with an extension internally threaded collar 3 which is threaded upon an externally threaded neck portion/1 formed upon the auxiliary section 2 of the vbody of the pen. A pen point 5 is carried by the primary section 1 of the body and a pen point 6 is carried by the auxiliary section 2 of the body. A suitable bulb 7 is associated with the point 5 for the purpose 'of supplying ink to the point 5 and ,a suitable bulb 8 is employed in conjunction with the point 6 for supplying ink tol the point 6. Snitable point holder sections 9 and 10 are employed for the purpose of supporting the respective pen points 5 and 6. A protector cap 11 is threaded upon the point holder portion 10 as fshown in Fig. 2 torv the purpose of protecting the point 6. A suitable vcap 12 is The compression lever 14 is pivotally mounted upon a supporting pin 15 and this supporting pin 15 is iirmly clamped between the primary and auxiliary sections 1 and 2 `of the body otthe-pen as clearly shown 'in Fig. 2. The compression lever 14 is also provided with upwardly curved end portions 16 as shown in Fig. 2 and these upwardly turned end portions 16 are normally seated within the channels 17 formed in the primary and auxiliary sections 1 and 2 of the body of the pen. It should be understood that when it is desired to either lill the bulb 7 or bulb 8, the compression lever 14 may be swung to the desired position thereby raising one end and lowering the other and upon releasing the compression lever 14 the suction within-the tube will cause the tube to he filled with ink through the sucking of the ink from a bottle or other receptacle up through the pen point into the bulb. The primary and auxiliary sections 1 and 2 of the body of the pen are dished or cut away as indicated at 18 located adjacent the respectiveends of the compression lever 14 to facilitate the insertion of the finger nail under the ends of the lcompression lever 14 for the purpose of swinging the lever to a proper position Vbody of the pen is to provide a means whereby red ink may. be employed in one end ot the pen and blue in the other, or any other desired or suitable color so that a contrast may be obtained. 'In this way the necessity of employing two separate pens may be overcome by retaining the two separate or distinct colors of ink in the same pen or rather in two separate compartments, each compartment being located at the opposite end of the body of the pen. It should be understood that certain detailed mechanical changes may be. employed in connection wit-h the present invention without departing from the spirit thereof so long as these changes fall within the scope of the appended claims.

I claim 1. A pen of the class described comprising a body having a primary and auxiliary sec? tion, means for securing said sections to gether, a pen point carried by each section, a reservoir bulb associated with each pen point, and a compression lever pivotally mounted between said sections and adaptedl to coperate with each reservoir bulb for the purposes of compressing the same.

2. A pen ofthe class described comprising a body formed of a pair ofsections, a reservoir bulb mounted within each section, said body provided with an elongated slot formed therein, a pivoted lever inclosed between said sections and fitting snugly within said slot, each end ofsaid lever being upturned for producing a compression knob adapted to engage a reservoir within the body of the pe and each section provided with a dished-out portion located near each end of the lever for facilitating the lifting of the lever and swinging thereof to a desired position.

3. A pen of the class described comprising a body formed ofa plurality of sections, a lever, a supporting pin clamped between said sections and pivotally supporting said lever between said sections, each section provided with a registering slot extending longitudinally thereof for the purpose of receiving said lever, a pen 4carried by each section, a reservoir secured to each pen, and

saidvreservoir adapted to be engaged by the respective ends of said lever whereby said reservoirs may be compressed for the purpose of facilitating the filling of the reservoirs when said lever is released therefrom.

4. A double ended pen of the class described comprising a plurality of sections, reservoir bulbs carried by said sections, and

.a compression lever interposed between said lever to permit the lever to be actuated for compressing the reservoir bulbs carried by said sections.

In testimony whereof I afix my signature in presence of two witnesses.

NORMAN H. A. NELSON. Witnesses: CLETUs BUSH, HELEN M. Dom.
