SAFETY DEVICE FOR INK-BOTTLES.

Specification of Letters Patent.

Application filed September 12, 1911.

Patented July 30, 1912.

Serial No. 648,915.

To all whom it may concern:

Be it known that I, WALTER PHARR, a citizen of the United States, residing at Metcalf, in the county of Greenlee and State of Arizona, have invented new and useful Improvements in Safety Devices for Ink-Bottles, of which the following is a specification.

The general object of the invention is to prevent the spilling or escapement of the contents of an ink-well or bottle when the latter is accidentally tilted or upset while in use, and to this end the invention consists in an attachment forming a closure for the ink-well and adapted to permit the introduction of the pen-point thereinto without the necessity of the removal from the bottle thereof.

Other objects will appear and be better understood from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a vertical section of an inkwell or bottle equipped with my device. Fig. 2 is a detail side elevation of the lower end portion of the device. Fig. 3 is a horizontal section on the line 3-8 of Fig. 1.

5 indicates an ordinary ink bottle in which ink is usually marketed, the bottle being constructed so as to serve as an ordinary ink-Well when the character or closure (not shown) is removed from the neck 6 thereof.

The device forming the subject matter of the present invention is herein shown as adapted to fit the particular form of bottle shown at 5 but it will be understood that I am not to be limited to thisspecific application of the invention since, from what will appear later, it will be manifest that the device may be modified without departing from the spirit of the invention, so as to fit into bottles shaped differently from that herein shown.

The attachment comprises a head or fun nel 8 having a depending inner wall or lip 9 arranged in spaced relation to the outer wall of the funnel and preferably tapered as shown.

10 indicates a shoulder at the lower end of the head or funnel which forms an abutment for the neck 6 of the bottle and 11 a tube which is connected to the head or funnel 8 by a neck 12. The neck 12 is herein shown as of greater diameter than the tube 11 and surrounded by an annulus of cork 13 or its equivalent which, when positioned on the neck 12 as shown, fits snugly into the neck 6 of the bottle, whereby, to prevent the escape of fluid there-around. The lower end of the tube 11 is permanently closed as at 14, and 15 designate oppositely disposed ports situated above the closed lower end of the tubeso as to permit of the passage of the ink 16 therethrough and into the tube. The ports 15 are valve-controlled so as to prevent the passage of ink into the tube at a point above the ports when the device is not in use, whereby, to prevent evaporation of the ink through the open end of the funnel. A convenient means for closing the ports includes a resilient U-shaped strip 17 suitably secured at its middle portion to the lower end of the tube 11, the limbs18 of the strip extending above the ports and carrying suitable valves 19 adapted to seal the ports and normally maintained in this position by the resiliency of the limbs 18. The spring action of the element 17 is relatively weak but sufficient, however, to keepv the valves in their closed positions.

20, 20 indicate spring arms which curve upwardly and outwardly from the inner faces of the valves 19 and bear on each other at points designated by 21.

It may be stated that the passage afforded by the tube and funnel is sufiicient to permit the' passage of a pen-point into the tube and of a pen-stock through the funnel and neck 12.

Referring to Fig. 3 it will be seen that the arms 20 do not extend completely across the lower end portion of the tube so that a space is afforded on either side of these arms to permit the passage of the pointed end of the pen when the latter is inserted into the fluid below the valves. However, since most pen-points such as that shown, diverge from the end thereof, a portion of the pen point will move between the bearing portions of the arms 20, 20 when the end of the penpoint enters the fluid so that the said arms with the valves connected thereto will be forced outwardly, thus permitting the en trance of a quantity of fluid into the tube equal, at least to the amount taken out by the pen when the latter is removed.

With this construction it will have been observed that the pointed end of the pen will be protected by its not coming into contact with or abutting any portion of the device when inserted thereinto. By virtue of the inner wall 9 it will be seen that a pas sage is provided for the ink remaining in the tube in the event of the bottles upsetting either while in or out of use, thus preventing the escape of the ink through the mouth of the head or funnel 8.

Although I have shown and described one embodiment of my invention it is to be understood that I am not to be limited to the specific arrangement and construction of parts since various changes will be made, within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the inven tion.

What I claim as new is:

1. An attachment for ink bottles comprising a funnel having a cylindrical portion and a reduced cylindrical portion extending inwardly through the neck of the bottle, an inwardly tapering wall depending from the upper end of the enlarged portion and formed integrally therewith, said tapered wall being disposed in spaced relation to the cylindrical wall of said enlarged portion, a tapering tube formed on the reduced portion of the funnel and extending within the bottle to a point adjacent the bottom thereof, said tube having its end closed and being provided with diametrically opposite ports adjacent its closed end, spring pressed valves normally closing said ports,

and arms extending inwardly from said valves and adapted to be engaged by the point of a pen to open the valves.

2. An attachment for ink bottles comprising a funnel having an enlarged cylindrical portion and a reduced cylindrical portion adapted to be received within the bottle opening, an inwardly tapering wall formed on the upper edge of said enlarged portion, said wall being in spaced relation to the cylindrical wall of said enlarged portion, a downwardly tapering tube formed on the reduced portion and extending to a point adjacent the bottom of the bottle, said tube having its end closed and being provided adjacent its end with diametrically opposite ports, a U-shaped spring secured to the end of said tube and carrying valves adapted normally to close said ports, and upwardly and outwardly curving arms formed on the valves and extending into the tube through said ports, the inner portions of the said arms adapted to be engaged by a pen point so as to be forced outwardly due to the wedging action thereof to open the valves.

In testimony whereof I aflix my signature in presence of two witnesses.

WALTER PHARR.
