Specication of Letters Patent.

Patented Ang. 1, l1911.

Application led July 17, 1909. Serial No. 568,233.

'.To, all whom 'it may concern:

13e it known that I, MAJOR F. SKIDMORE, afitizen of the' United States, residing at Toledo, in the county of Lucas and State 0f Ohio, have invented a new and useful 'Fountain-Pen, of which the following is a specification.

. My invention relates toa fountain pen of the kind having a collapsible ink reservoir housed within its stem and has for its object to provide means to more evenly collapse said reservoir initiatively to its filling and soy arrange the compression means that the same may be readily housed within the stem without undue encroachment upon the space allotted to the reservoir and in'such a juxtaposition thereto, that without injury to its walls, v said reservoir may be collapsed for filling for a greater portion of its length as well as of its girth.

The objects of my invention are accomplished as, hereinafter described and illustrated in the drawings in which- Figure 1, is a view partly in sectlon 'of a fountain pen const-ructed in accordance with my invention and showing the normal posi.-

tion of my compression means and the reservoir` in full. Fig. 2, vis a like View but showing the mechanism in the position in which the reservoir is collapsed.v Fig. 3, is

' an isometric view of my compression meehanism. Fig. 4, is a sectiont-hrough the pivotal joint, and Fig. 5, is a view showing a method of attaching the pressure plate to the rocker bar. Fig. 6, is an end view of the barrel showing the reduced nipple and the slot for the pressure-lever.

The fountain pen illustrated in the drawings is of usual form and its head (1) is formed to socketand support a pen 2, being-also provided with a supply tube and opposite to the pen and the supply tube, said head is diametrically reduced to form .a shoulder odset 4 and again reduced 1n d1- 'ameter to form a nipple portion 5 upon which a sack 5 vfor the ink, or a reservoir of collapsible material is mounted.' The shoulder offset 4 is' of a size to forcibly' telescope into the bore 6 of a barrel orI lstem 7 which has its opposite end closed by a head.

8. The head 8 is provided with a'threaded extension 8 of a reduced diameter. The barrel 7 is of a v length to house the lnksack within its bore and to compress said sack for iilling, I have provided a pressure plate 10 which is of a length to extend from near the nipple to the free end of the sack, and as a means to bear the plate upon the sack I have coupled the head end 10 of the plate to the free arms 11 of a lever 12 which are so angled near the head 8 that short arms 13 are formed which are of a:

length slightly less than the diameter of the bore 6' being connected by means of an integral bight 14. The long arms 16 and the short arms 13 of the lever' 12 and the con is provided with an end bore 16 in which is pressed a stem 17 the free end of which is upset to form a head 18. The pressure lever 19 is pivoted to this head and extends therefrom between the arms ll/through the slot 20 a suitable dist-ance outward from the head 8 andis provided with a terminal knot 21. To impart motion to the arms 11, said pressure lever is coupled to the arms about .midway of their length by a pivot 22 com mon to the arms and to the lever. By the plate, angled lever and bar thus arranged and housed within the bore of the stem 7 collapsing pressure may be brought to bear upon the ink sack by pressing upon free end of the lever 19 which results in rocking of the angled lever 12 and depresses the free end upon the ink sack, while the free end of the pressure plate is brought to bear upon the ink sack by the pressure directly imparted by the lever 19 to collapse the head and the pressure bar being made ,of

spring wire which is flexed to collapse the reservoir will return the parts to their normal position when pressure upon the lever 19 is released, with the result that the ink sack is lilled'by external pressure. The free end of t-he lever 19 is protected by means of cap 23 which is threaded to the extensionv such purpos e is telescoped upon the headend 8.

What I claim is,

l. A fountain pen, having a tubular stem and a compressible ink-sack; a pressure plate, a leverl adapted to roel: within the cavity of the tubular stein and having `its inner end coupled to the inner end of the pressure-plate, and a spring operating lever, fixed to the head end of the stem, and pivotally connected to rock leverj adapted to impart with the rock-lever a parallel compressing motion to the pressurev plate.

2. A fountain pen, having a tubular stein and a. housed in ink-sack, compressing means for saidinksack, comprising a pressure-plate, an angled lever, havingthe end of its long arm fixed to the end of the pressure-plate adjacent the nipple for the inksack, and its short yarm adapted to rock upon the Wall of the stem, a spring pressure bar, extended from the nipple, being pivotallyeonneeted to the long arm of the angle levell about midway of its length, and

ladapted to bearL upon the free nd of the pressure-plate. l

3. A fountain pen, having an lnk-sack housed Within a built-up tubular stem; compressing means for the .ink-sack, comprising f a; pressure-plate, lever arms Coupledl to the .the long arms of the angled levers about mid-Way oi" their length, and adapted to bear upon the free end of the pressureplate, and a slot in the stern for the extensin of the spring pressure-,bar and permitting its movement across the area of the stem. I

In Witness whereof, l have hereunto set my hand this l0 day of May 1909..-2'
