FOUNTAIN-PEN.

To all whom it may concern: I

Be it known that I, ERNEs'r WINNE, a citizen of the United States, and a'resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Fountain-Pens, of which the following isa specification.

This invention relates'to certain new and useful improvements in fountain pens, and particularly to that class of fountain pens which are provided with an automatic filling device composed of a compressible reservoir and means for excluding the air from the reservoir so as to permit the ink to The object of my invention is to provide a new and improved pen of this kind which is simple in construction, can be manipulated with the least expenditure of time and effort, and which does not require'the detaching or preliminary shifting of any parts whatever, nor the use of any other 1nstrument thah the fingers directly applied; which does not have any parts projecting from the side of the barrel to interfere with the convenier t holding of the pen when in use, or detract from its graceful appearance; and in the operation of which there is no tendency to force the pen toward the bottom of the ink well; and which improvement is strong and durable, and operates rapidly.

In the accompanying drawings in whichlike letters of reference indicate like parts in all the figures :,Figure 1 is a longitudinal section of my improved self-filling foun tain pen. F ig. 2 is an enlarged detail longitudinal sectional View of the upper end of the barrel, the plunger, and the means for moving the same. Fig. 3 is a transverse section on the line a-a of Fig. 2. Fig. 4 isa transverse section on the line b-b of Fig. 2. Fig. 5 is a transverse section on theline cc of Fig. 2. Fig. 6 is a perspective view of the sleeve cam, parts being broken away.

The pen barrel 1 contains a compressible ink reservoir 2 which preferably consists This bag can be compressed so as to force out the air by means of a strip 3, which is secured to a spring strip 4 placed in the barrel along side of the reservoir, both of which extend longitudinally of the reservoir. This spring strip 4 or flexible strip at its lower end rests against the front plug,the part contalning Specification of Letters Patent. Patented Aug. 15, 11916.. Application filed May 29, 1915.

move longitudinally.v When the compressible reservoir is filled and distended by the ink in the same, the strip 4 is straightened out and rests against the wall of the barrel. When the plunger 5 is moved inward longitudinally, the spring strip 4 is bent at its center and presses the strip '3 against the ink reservoir, thereby flattening or compressing the reservoir and forcing out the ink or air so that when the pressure on the plunger 5 is removed the distending reservoir can flatten out the spring. strip 4. What have described so far I do not claim 'as my invention.

In my invention the plungen 5 is guided to move lengthwise of the barrel, and also is prevented from turning, by means of a pin or other'pr'ojection 8 extending from each of two opposite sides of the same, beyond the partition 7, through two opposite longitudinal slots 9 formed inthe neck 10 of the barrel beyond the partition 7. A sleeve 11 fitting on the cylindrical partition 7 and neck 10, and preferably having its outer surface provided with longitudinal riflies,or roughened in any other way that will facilitate its being firmly grasped with the fingers,fits snugly but capable of easy-turning on the "partition and neck; and on the inside of this sleeve 11, bearing directly on the neck, a metal sleeve or bushing 12 is firmly inserted, which has its inner edge shaped as a cam edge, which cam edge bears upon the ends of the projections 8, which projections extend to the inner diameter of the sleeve 11 at that part not provided with cam sleeve 12. The cam sleeve is thus mounted to rotate on the neck by manipulation of the sleeve 11 of which it is a fixed part. To prevent the sleeve 11 and its cam sleeve bushing 12 from moving longitudinally a sleeve 13 is slipped upon the neck 10 and rests against the outer ends of the

sleeves

11 and 12, thus holding the opposite end of the sleeve 11 against the shoulder at the end of the main portion of the -barrel. The sleeve 13 has two diametrically opposite longitudinal ridges 14 which pass into the grooves 9 and thus prevent the sleeve 13 from revolving. The outer edge of the sleeve 13 is flush with the extreme outer edge of the pen barrel, which is the outer end of the slotted neck. To prevent the sleeve 13 from moving longitudinally an end plate 15 is secured on the end of the barrel to overlap the outer edges of the sleeve 13, and this end piece is preferably held in place by providing it with a threaded stem 16 which can be screwed into the outer end of the neck 10, which is internally screw threaded for the purpose of receiving this screw.

The sleeve 11 can be turned on the neck in either direction, but cannot move longitudinally, as it is confined by the sleeve 13, which cannot turn on account of its internal ribs or splines 14, and cannot move lengthwise on -the inner end of the inserted metal sleeve 12,

which is secured on the sleeve 11, act on the projections 8 and press the plunger 6 lengthwise of the barrel in the direction of the penholding end of the same, thereby upsetting the spring strip 4:, whereby the strip 3 which is attached to the middle of the spring 4 exerts .a uniform pressure on the side of the compressible reservoir 2, thus expelling the ink and air therefrom, but as soon as the point of the cam edge 19 has passed the projections 8 the inrushing ink distends the reservoir 2, flattens out the spring strip 4, and pushes the plunger 5 outward again. Hence it is only necessary to give the sleeve 11 an axial movement in either direction of onequarter of a revolution, it being understood that there are four cam'projections 19 on the sleeve 12. In so turning the cam sleeve, when the points of the cam pass the projections 8 the latter return with a snapping movement into the bottom of the notches between the cam points, and this single pres sure and release movement of the cam sleeve is sufficient to expel the air from the reser voir and to permit the reservoir to be filled with ink after it has thus been compressed and permitted to expand. The cam sleeve 12 can be turned in either direction as the cam edges 19 incline at an equal angle in both directions. Therefore, to fill the pen, all that is necessary is to dip the pen point into the ink and to grasp the barrel firmly between the pen point and the sleeve 11 and then turn said sleeve in either direction a quarter revolution, or until the mechanism compressing said reservoir, comprising a V plunger, gu1ded to move lengthwise, means for holding the plunger against rotary movement, a rotary sleeve provided with in ternal cams to act on said plunger and means secured on the barrel adjacent to the cam sleeve, to prevent longitudinal movement of the latter, substantially as set forth.
