FOUNTAIN-PEN.

Application filed June 9, 1915.

To all whom t may concern:

Be it known that l, Onrn SHAcnnLronD, a citizen of the United States, residing at Fairmont, in the county of Marion and State of lV est Virginia, have invented certain new and useful improvements in Fountain-Pens, of which the following is a specification.

My invention relates to fountain pens embodying an ink holding bulb, which may be properly manipulated, for feeding the ink to the pen point or for refilling the bulb, without removing it from the pen handle.

An important object of the invention is to provide a fountain pen of the above mentioned character, which is simple in construction, inexpensive to manufacture, convenient in use, strong and durable.

,A further object of the invention is to provide a-fountain pen of the above mentioned character, so constructed that the sliding or movable sleeve ordinarily employed to cover an opening which leads to the ink holding bulb, is dispensed with, whereby the pen may be operated more conveniently and quickly.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of a fountain pen embodying my invention,

Fig. 2 is an enlarged central vertical longitudinal sectional view through the same, with parts in elevation,

Fig. 3 is an enlarged horizontal sectional view taken on line 3 3 of Fig. 2, parts being in elevation, and

Fig. 4 is a side elevation of a tube.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a pen handle, having a reduced forward extension 6, fitting tightly within a preferably metallic casing or tube 7, and held therein by any suitable means. This casing or tube is provided upon one side with a longitudinal opening 8, for a purpose to be described.

The numeral 9 designates an ink holding bulb or sack, preferably formed of suitably Specification of Letters Patent.

Patented Mar. 20, 191'?. Serial No. 33,023.

iiexible rubber, having an ink feeding tube 10, secured to its forward end. This tube is preferably formed of hard rubber.

The tube 10 extends through pen holding means 11, of any well known or preferred construction, arranged within the forward end of the metallic tube 7, and adapted to receive a pen point 12, between it and the tube 7. The tube 10 feeds the ink to the pen point 12, as is obvious.

Surrounding the metallic casing or tube 7 is a relatively stationary outer sleeve 13, preferably formed of flexible rubber, with its outer surface preferably flush with the outer surface of the pen handle 5, as shown. Arranged inwardly of the sleeve 13 is a preferably metallic plate 14, operating within or through the opening 8, and in contact with one side of the bulb 9. This plate is substantially co-extensive in length with the bulb, and serves to compress it throughout its entire length, when the plate is moved inwardly. This compression plate 14 is secured to the sleeve 13 by means of a pin or rivet 15, or other suitable means.

In the use of the pen, when it is desired to fill the bulb, the operator presses the rightside of the sleeve 13, preferably with the thumb, such sleeve moving inwardly to effect aV corresponding movement of the compression plate 14. This movement of the plate 14 compresses the bulb 9, which is held compressed while the pen point and tube 10 are dipped into the ink, at which time pressure is removed from the sleeve 13. The sleeve 13 and bulb 9, automatically expand to their original condition, whereby the ink is sucked or drawn into the bulb. l/Vhen the pen is being usedrfor writing, the flow of ink to the pen point maybe regulated, by exerting pressure upon the sleeve 13, preferably by means of the thumb, which pressure is transferred to the bulb through the medium of the plate 14. The compression of the bulb forces an additional supply of ink to the pen point. l

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the 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 claims.

the rigid casingy a fieXible sleeve surround-` ing the rigid casing and covering the longitudinal opening thereof, a compression plate disposed within the longitudinal opening between the bulb and the lleXible sleeve, a pin arranged approximately equidistant from the ends of the compression plate and connecting the compression plate and the flexible sleeve, a pen holding device mounted within the free end of the rigid casing, a pen point carried by the pen holding device,

Copies of this patent and a tube connected with the bulb and discharging ink to the pen point.

2. In a fountain pen, a pen handle carrying a reduced extension, a metallic sleeve mounted upon said reduced extension and having a lateral opening therein7 a soft rubber sleeve arranged about and co-eXtensive with the metallic sleeve, a compressible bulb contained within said sleeve, a pen point holding device carried by the metallic sleeve, a tube connecting the bulb and pen point.

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