4 claims.

This invention relates to an ink eradicator applicator and has for the primaiy object the provision of a device of this character which will provide a portable or pocket size container in which different ink eradicator fluids may be separately kept for indefinite periods of time against evaporation or wastage and includes means whereby rst one fiuid and then the other may be applied to a selected area for removing ink therefrom Without danger of flooding the area' or areas adjacent thereto with either ci the fluids, said means cooperating with a suction means for the easy and quick lling of the container with the uids.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as Will be hereinafter more 'fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation illustrating an ink eradicator applicator constructed in accordance with my invention.

Figure 2 is a vertical sectional view illustrating the device.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a sectional view taken on the line 4 4 of Figure 1.

Figure 5 is an enlarged side elevation illustrating one of the fiuid applying pins of the applicator.

Referring in detail to the drawing, the numeral 5 indicates an elongated tubular container having one end closed by a head t. The size of the container is such that it may be carried within a persons pocket like a pen or pencil. A partition 1 extending from the head I5 within and to the open end of the container forms the latter into separate compartments 8, one adapted to receive one of the usual fluids employed for eradicating ink while the other compartment receives the other fluid. The open end of the container 5 is normally closed by` a cap 9 having a frictional tit therewith and provided with offsets I provided with ports II through which slide stems I2 of plungers I3. It is preferable that the stems i2 have a sliding Iit with the walls of the ports I I to prevent the iiuids from leaking past the cap. The free ends of the stems I2 are provided with finger pieces I4.

The container adjacent the cap 9 is provided with external screw threads to mesh with internal screw threads formed on a closure vcap I5 employed to normally house the stems of the plungers, as clearly shown in Figure 2.

The head 6 has a slight taper thereto with the free end thereof shaped to form spaced projections l6 and extending through the head 6 and the projections I6 thereof are passages I'l opening into the compartments of the container. A portion of the passages Il has the diameter in` creased to form valve seats IS. The valve elements I8 form integral partsof pins i9 that ex'` tend outwardly of the head' at the pointed portions and form applicator elements.

Perforated plates 20 are arranged in the compartments of the container 5 against the head and form seatsfor coil springs 2i acting on the valve elements i8 to retain them in seated, position. The springs may be made oi steel or any other metal suitable for the purpose. It is preferable that the valve elements as well as the perforated plates be provided with enlargements 22 to enter the ends of the coil springs to prevent them from shifting out of position. It is preferable that the surfaces of the pins 9 be roughened to retard the flow of the uid thereover when said valve elements are in unseated position. The perforated plates are removable from the com'` partments of the container and are held in seated engagement with the head by lugs 23 formed on the interior of the container and overlying the perforated plates. The perforated plates are provided with notches 24 through which the lugs may Vpass when applying and removing the perforated plates from. the container. I

The perforated plates may be otherwise removably secured in place, such as utilizing screws or other similar fasteners.

In removing ink from a selected area by ink eradicator fluids where two different fluids are employed, it is the customary practice to apply first one uid and then the other and the present invention is constructed to permit this to be accomplished with ease and without danger of flooding the area or areas adjacent to the area in which the ink is to be removed. In use, the device is grasped as a pen or pencil and the selected pin or applicator element is brought into engagement with the area with suiiicient pressure to unseat the valve element attached thereto so that the selected uid may flow slowly onto the area. As soon as the pressure is released on the applicator element, the valve seats and cuts olf the further flow of uid to the area. After the proper amount of the uid has been applied to the area the device is turned in the hand of different fluids, the cap I5 is removed and the p head is positioned within a container having one of the fluids therein and one of the plungers is moved in the direction of the cap 9 drawing the uid into one of the compartments. The same operation is repeated in connection with another container having the other fluid therein by the movement of the other plunger in the direction of the cap 9. After the compartments or chambers 8 have been filled with the fluids, the cap l5 is replaced on the container leaving the stems of the plungers therein whence said stems are protected and prevented from being accidentally engaged as to cause an inward movement of the plungers.

If desired one-half of the head 6 may be of one color denoting one of the fluids and the other half of another color to denote the other fluid, as clearly shown in Figure 1.

A cap is frictionally applied to the head B and a portion of the container 5 and is provided with pockets 26 to receive and normally protect the free ends of the applicator pins I9.

While I have shown and described the preferred embodiment of ymy invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. In an ink eradicator applicator, a container having a fluid compartment, a head closing one end of the container and having a passage communicating with the compartment and extending through the end of the head, a valve seat formed in said passage, an applicator element in said passage and extending outwardly therefrom at said end of the head and provided with a roughened surface for applying fluid to an area, spring means Iacting on the applicator element to normally close the passage.

2. In an ink eradicator applicator, a container having a liquid compartment, a head closing one end of the container and having a passage communicating with the compartment and extending through the end of the head, a valve seat formed in said passage, an applicator element in said passage and extending outwardly therefrom at said end of the head and provided with a roughened surface for applying fluid to an area, a perforated plate removablymounted in the compartment Lof the container and overlying the passage, and a coil spring interposed between said plate and the applicator element.

3. In an ink eradicator applicator, a container having a liquid compartment, a head closing one .end of the container and having a passage comoperating in the compartment of the container I and including a stem extending through the cap, and a closure cap removably mounted on the container and housing the stem of the plunger.

4. In an ink eradicator applicator, a container having a, liquid compartment, a head closing one end of the container and having passages communicating with the compartment and extending through the end of the head, a valve seat formed in said passage, an applicator element in said passage and extending outwardly therefrom at said end of the head and provided with a roughened surface for applying fluid to an area, a perforated plate removably mounted in the compartment of the container and overlying the passage, a coil spring interposed between said plate and the applicator element, a removable cap closing the other end of the container, a plunger operating in the compartment of the container and including a stem extending through the cap, a closure cap removably mounted on the container and housing the stem of the plunger, and a cap frictionally applied to the head and a por-l tion of the container and provided with a pocket to house the free and applicator element.
