Nov. 28, 1950 G. w. OAKES FOUNTAIN PEN FILLING DEVICE Filed Jan. 11, 1947 INVENTOR. George 2, Uakes F5. qzE- llrrllllillllilrllla u Patented Nov. 28, 1950 UNITED STATES This invention relates to a device which is designed and adapted to be applied to a container or bottle of ink and to receive a fountain pen for the purpose of filling the pen with ink.

The principal object of the invention is the provision of a device of the indicated character embodying improvements whereby the writing end portion of a fountain pen may be easily insorted into the device and then be held in a fluidtight manner, 'so that the ink may be delivered to fill the pen without waste resulting from leakage, and to subsequently close or seal the device to prevent evaporation or deterioration of the ink in the container or bottle after the pen has been withdrawn from the device.

With the foregoing, other objects of the invention will appear when the following specification is read in conjunction with the accompanying drawing, in which:

Fig. 1 is a view showing a device embodying the features of the present invention applied to an ink bottle, the device being partly in section and partly in elevation and certain features being shown in dotted lines.

Fig. 2 shows the device applied to the ink bottle in use to fill a fountain pen, a part of the pen barrel being broken off.

Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view showing a modification of the actuating means.

Referring now more particularly to the drawing, it will be apparent there is shown a body H] which is made wholly of rubber. The body ID is formed to provide compressible and expansible means consisting of bulb I! between a tubular outlet portion l2 and an inlet end portion 13. A diaphragm 14 formed from the material of the body I is integral with the bulb H at the outlet side thereof. The diaphragm has slits 15 which radiate from a central point in line with the longitudinal axis of the outlet portion I2.

The inlet end portion l3 has connected therein suitable valve means l6 which is shown in dotted lines. The inlet portion l3 also has an adaptor ll thereon for the purpose of attaching the device to the outlet neck of a receptacle or bottle [8 containing a supply of ink. The valve means i 6 is of the type disclosed in United States Patent No. 2,494,518 granted to me January 10, 1950.

The bulb I! being resilient is adapted to be manipulated to receive and discharge or expel quantities of ink. When the bulb expands by 6 Claims. (C1. ZZZ-63) withdrawing the compression action thereon, a quantity of ink is drawn into the bulb, and when the bulb is compressed by squeezing it, the ink is discharged or expelled from the bulb. It is to be understood these manipulations are performed when the device as applied to the bottle is inverted, as shown in Fig. 2. The bottle is grasped with one hand and the bulb l l is manipulated with the thumb and forefinger of the other hand. The valve means it cooperates with the action of the bulb ii to control the flow of ink from the bottle into the bulb. The diaphragm Hi also cooperates with the action of the body ill to pass the ink from the bulb H into the outlet portion l2 when the bulb is compressed and to stop the flow of ink when the compression ac-' tion on the bulb is withdrawn.

The outlet portion l2 being made of rubber serves as an expansible and contractible socket or nipple into which the writing end of a fountain pen is may be inserted for the filling operation, as shown in Fig. 2. The outlet portion I2 is cylindrical.

In accordance with the present invention improved means are provided for clamping the writing end of the fountain pen in the outlet portion I2 and for releasing it. Said means includes a substantially cylindrical tube or sleeve 2% having a transverse cut 2| part way through providing an attaching section 22, and a clamping section 23, which latter 'is longitudinally split and has laterally projecting spaced lugs 2d. The section 23 being split or divided longitudinally at one side may be expanded and contracted. It is to be understood that the sleeve 20 is made of metal or other suitable material inherently resilient or springy. The attaching section 22 is indented to provide small projections 25 on the inside which enter small holes molded in the outlet portion I2. If desired, small pins may be used in lieu of the projections 25. These projections or pins securely hold the sleeve 20 in place.

Use is made of a cross-sectionally arcuate member 25 adapted to receive and apply pressure on the outlet portion I2 in cooperation with the clamping section 23. The member 26 is approximately equal in length to the length of the clamping section 23 and is disposed between the outlet portion l2 and the section 23 at the split in the latter, as shown most clearly in Fig. 3. The member 26 is of a width to close the gap formed by the split in the section 23 and to overlap the adjacent portions of said section to a considerable extent. A lever 21 having a cam 28 is pivotally between the; lugs '24.

mounted between the lugs 24 by means of a pivot bolt 29 and nut 30 or the equivalent thereof. The lever 21 may be manipulated to cause the cam 28 to exert pressure on the member 26 or to withdraw the pressure. When the pressure of the cam 28 is exerted on the member 26 it is applied by the latter in cooperation with the clamping section 23 on the outlet portion l2, thereby compressing the latter. Hence, when the writing end of a. fountain pen is inserted into the outlet portion l2 it will be securely clamped in a fluid-tight manner as the outlet portion I2 is compressed. When the lever 21 is swung to its down or releasing position shown in Fig. l, the writing end of the pen may be readily inserted into or be withdrawn from the outlet portion I24. A cap or stopper 3| is pivoted to the lugs 24, as at 32. This cap or stopper aids in sealing the device to prevent evaporation or deterioration of: the ink when the device is not in use. The slitted diaphragm l4 permits ink to pass through it when under applied pressure", but will not. pass any ink under gravity pressure alone. This will permit the device as applied to the bottle to be laid on its side in a. drawer, if desired, without ink flowing out, in case the cap 3! is carelessly left, in an open. position- In order to help remove all of the ink from the bulb NY and to expel the ink more rapidly, use may be made of a substantially round compressible body 33 of cellular material such as sponge rubber. The body in the form of a ball may be disposed within the bulb I las shown;

In lieu of the cam lever 21, use may be made of aheaded. screw 374 operable in a nut 35 fixed The inner; flared end 36 of the screw 34 contacts, the pressure member 26, and. there being a central. projection extending into: a hole; in the-member '29- to keep it from slipping out. of place. It is obvious, that by turning the: screw i l in opposite directions, the outlet portions I? may be compressed and allowed to expand for the stated purposes.
