LEVER-FILLER FOUNTAIN PEN. I
Application filed iTanuary 6, 1922. Serial no: 527,321.
1 '0 all whom it moyconceam.
Be it known that I, W'ILLIAM P. De l/Vrr'r, a citizen of the United States, residing at Somerville, inthe county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Lever-Filler Fountain Pens, of which the following is a specification.
This invention relates particularly to means for compressing the ink holding sack of a fountain pen, the object of the invention being to provide a cheap and. easily constructed device, whereby the lever, which actuates the presser, may be pivotally and detachably connected to the casing Without drilling holes in said casing.
' The object of the invention is further to provide a lever and a support therefor which may be rigidly and securely positioned upon the casing of a fountain pen and yet may be easily attached to or detached .therefrom.
Furthermore, the object ofthe invention is to provide a device ofthe character set forth which can be struck up out of sheet material by certain tools, thus greatly reducing the expense and. greatly adding to the accuracy of the device.
The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.
Referring to the drawings Figure 1 is a sectional elevation of a portion of a fountainpen casing with my improved sack compressing mechanism attached thereto.
Fig. 2 is a perspective view of the sack compressing mechanism, a portion of the same being broken away.
Fig. 3 is a detail longitudinal sectional elevation illustrating a portion of the presser bar and the manner of pivotally connecting the lever thereto.
Fig. 4 is a detail section taken on the line 44, Figure 1.
Fig. 5 is a detail section taken on the line 5-5, Figure 1 with the ink sack omitted.
Fig. 6 is a detail section taken on the line 6-6, Figure 1.
Like numerals refer to like parts throughout the several views of the drawings.
In the drawings, 10 is the casing of a fountain pen; 11 an ink sack; 12 a station-- ary member to which the open end of the ink sack is secured. 13 is a presser bar which is pivotally connected to a lever 14. The lever 14 is U-shaped in cross section and is provided'at one end thereof with a flattened portion 15 terminating in a hook 16 which extends through two holes 17 and 18 pro vided in the presser bar 13, the lever 14 is pivotally connected at 19 to a plate 20. The opposite ends of said plate 20-are U-shaped in cross section at 21 and 22 and said plate is connected, by a projection 23 formed thereon, to the flattened portion 24 of asplit ring 25 which is located inside the casing Q10 and is rigidly positioned in said casing by frlctional contact with the inner surface thereof. The end of the lever 14, opposite to that at which said lever is pivoted to the plate 13, is provided with oppositely disposed cars 26 and 27, which, when the lever is located in the position illustrated in F igure 1,'namely, within a slot 28 provided in the wall of the casing 10, are adapted to engage oppositesides of the U-shaped portion 22 of the plate 20, thus detachably engaging said plate and firmly positioning the lever 14 relatively thereto within the slot 28. The
It will be understood that the ring 25 and the plate 20 are. connected. together by the projection 23 which is struck up on the plate 20 and projects into a similarly formed indentation 29 formed in the flattened portion of the ring 25. The portion 21 of the plate 20 is in a like manner connected to the lever 1 1 as illustrated in Fig. a, in which the pro jections 19 on opposite sides of the U-shaped portion of said lever project into like formed like, and firmly securing, by these means,
In fountain pens having a The general operation of the device hereinbefore described is as follows :-Assuming the parts to be in the relative positions illustrated in Figure 1 and it is desired to fill the sack 11 with ink, the lever 1a is pulled outwardly from the position shown in full lines, Figure 1, to the position shown in dotted lines, this operation being rendered easy and.
convenient by a notch 31. provided in the outside of the casing 10 and into which projects afinger piece 32 forming a part of the free end. of the lever 1 1. lVhen the lever 14 is thus operated, the end 15 of said lever, which is pivotally connected to the presser 13, will. force said presser inwardly and thus compress the sack, the pen is then inserted in the ink and the lever moved from the dotted 'line to the full line position, Fig. 1, whereupon the partial vacuum in the sack 11 caused by the operation of the lever hereinbefore set forth will cause the ink to flow from its receptacle into said sack in a manner well known to those skilled in this art.
In the foregoing specification, the presser bar 13 is described as being pivotally connected to the lever 14: by means of a hook and the presser bar is therefore supported upon the lever. It is evident, however, that with out departing from the spirit of my invention, the presser bar may be connected to or supported upon the casing of the pen 10 in any desirable manner, as for example, in the manner illustrated in United States Patent to S. Josselyn, No. 1,214,810, January 30, 1917, and if such a construction were used, the free end 16 of the lever let would bear against the outer face of the presser bar instead of being connected to it.
I claim 1. A fountain pen having in combination, a casing a sack of flexible material-adapted to contain liquid and enclosed within said casing, open atone end thereof and closed at the opposite end, a presser located within said casing and arranged to bear against said sack, a lever U-shape'd in cross section pivotally connected to said presser and normally positioned in a slot provided in the wallof said casing and a plate rigidly positioned in said casing, the opposite ends of said plate being U-shaped in cross section, one U- shaped end of said plate projecting into a U-shaped portion of said lever to which it is pivotally connected and a pair of oppositely disposed ears on the opposite end of said U-shaped lever adapted to engage opposite sides of the end of said plate opposite to that at which saidlever is pivoted thereto, whereby said lever is held detachably engaged to said plate in said normal position.
2. A fountain pen having, in combination, a casing, a sack of flexible material adapted to contain liquid and enclosed within said casing, open at one end thereof and closed at the opposite end, a presser located within said casing and arranged to bear against said sack, 'a lever U-shaped in cross section pivot-ally connected to said presser and normally positioned in a slot provided in the wall of said casing and a plate rigidly positioned in said casing, the opposite ends of said plate being U-shaped in cross section, one U-shaped end of said plate projecting into a U-shaped portion of said lever to which it is pivotally connected by projections on one of said parts extending into indentations in the other of said parts, and a pair of oppositely disposed ears on the opposite end of said U-shaped lever adapted to engage oppositesides of the end of said plate opposite to that at which said lever is pivoted thereto, whereby said lever is held detachably engaged to said plate in said normal position. i
In testimony whereof I have hereunto set my hand.
WILLIAM P. DE
