SELF-FlLLlNG FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed March 30,1906. Serial No. 308.873.

- rangement of parts, which I will now proceed to describe and hereinafter claim in connection withthe accompanying drawings, forming part of this specification, wherein Figure 1 illustrates aside elevation of my improved fomitain-pen, partially in section, the sac and collapsing device being'shown in elevation. Fig. 2 is an enlarged longitudinal central section of my improved fountain-pen, the being in elevation and the pen-stock onnozzle broken away. Fig. 3 is a view similar to'Fig. 2 and showing the. manner in which the sac is collapsed. Fig. 4 is an enlarged cross-sectional view taken on a line a a in Fig.2 and'looking in the direction of the arrow, and Fig. 5 is a fragmentary view showing the manner of pivotally mounting the links and the tongue which supports the same.

Similar numerals of reference indicate correspondin parts in the several views. In the awings, the numeral 1 indicates the barrel of my improved fountain-pen which supports or carries inany desired manner,'such as screweconnected or frictionseen, Fig. 3.

ally held, the usual pen stock or nozzle 2, which in turn is provided with a passage 3 for the writing fluid. The passage 3 communicates with the pen 4'and'feeder-bar 5 in the usual way. I provide the upper end of the nozzle 2 with a reduced portion or neck 6, with which the passage 3 connects. To the neck 6 a rubber sac 7 is attached.

Various connections may be employed, but I prefer to stretch the lower end 8 of the sac 7- over the neck 6, thereby holding it in position by the elasticity of the rubber; As will be the neck is undercut at the base thereof, thus precluding any tendency of the sac to work ofl.

In order to fill the sac or reservoir 7, I provide an improved means adapted to collapse or fiattenit. When the sac is thus collapsed or flattened, which by my improvements occurs for the greater part of its length, the air therein has been forced out, whereby a partial vacuum is'caused, and when the sac is again allowed to expand the pressure of the outside atmosphere will force the ink into the sac.

In order to properly exhaust or force the air .from the sac, it is necessary that the flattening or pressure should be uniform, and to produce such an effect I provide a shoe 9, which is adapted to partially surround the sac 7, as shown in Fig. 4. The shoe 9 is pivotally supported by a'frame 10, which at its lower end 11 is provided with a cylindrical clamp or loop 12, which is adapted to tightly fit a shoulder 13, carried by the nozzle As shown, the shoe 9is approximately the length of the sac 7 and is, as has been stated,

pivotally supported by the frame 10 by means of the links 14.

ported by the frame 10 in eyes 15, which are formed on the ends of the tongues 16, the latterbeing integral with the frame 10, and are formed by stamping in a manner well lmown, as shown in Fig. 5. The shoe 9 is rovidedwith eyes 17 in a similar manner. The links 14 are of equal length, so that when the shoe is operated or pulled-up a parallel motion is produced, whereby the shoe 9 is caused to impinge u on the sac 7 equally throughout its lengt For operating the shoe I provide a spindle 18, which passes through thecap or head-19 at the upper end of the barrel. An operating-knob 2.0 is provided for manipulation. The spindle 18 is rovided with an eye 21, which supports a mk 22, the other end of said link being connected to the shoe 9 by means of the eye 21.

The cap or head 19 serves to limit the up- Ward movement of the spindle 18 to prevent the links 14 from crossing the center.

If desired, the links 14 may be of such length as to prevent their crossing the center by reason of the total collapse of the sac before said links can attain a horizontal position. i

The links 14 are sup porting the frame by the nozzle 2 as Well as the sac-7 the Whole device may bedrawn out and cleaned by unscrewing knob When collapsing the sac, the shoe forces the same against'the opposite wall of the barrel.

Fig. 2 shows the sition.

Having now described my, invention, what I claim, and desire to secure by Letters Patent, is-

l. A. fountain-pen, comprising a barrel, a nozzle carried thereby, a collapsible sac or reservoir attached to thenozzle, and means carried by said nozzle adapted to collapse the sac throughout the length thereof.

2. A fountain-pen, comprisinga barrel, a nozzle carried thereby, a collapsible sac communicating with and connected to the nozzle, a frame carried by the nozzle, a shoe 'IIXOV- ably mounted upon said frame and adapted to impinge upon said sac throughout substantially the length thereof, and means for operating said s ioe.

3. A fom'itain-pen, comprising a barrel, a nozzle carried thereby, a collapsible sac communieatiu g with and connected to the nozzle, a frame carried by the nozzle, a shoe ivotally mounted upon said frame and ad fipted to impinge against said sac throughout substantially the length. thereof, and means for operating said shoe.

sac in about its normal pois merelyillustrative,

said links adapted to impinge against said sac, and means adapted-to operate said-shoe.

' 5. A fountain-pen, comprising a barrel, a nozzle carried thereb a'collapsible sac communicating with and connected to the nozzle, a frame carried by said nozzle provided with a plurality of pivotal links, a shoe caried by said links adapted to impinge against said sac throughout substantially the length thereof, and an o erating-rod carried by said shoe and extending through the rear end of the barrel.

6. A fountain-pen, comprising a barrel, a nozzle carried thereby, a collapsible sac communicating with and connected to the nozzle, a ame carried by the nozzle and provided with a plurality of pivotal links, a shoe carried by said links adapted to impinge against said sac throughout substantially the length thereof, means adapted to operate said shoe, and means adapted to limit the movement thereof.

7. A device for collapsing the flexible reservoirs of self-filling fountain-pens, comprising an elongated frame, an elongated shoe pivotally connected to the frame and adapted for a movement in parellelism therewith, and means for o erating said shoe.
