'This invention relates to improvements in manicuring instruments, and has for its chief object to provide animproved cuticle remover. In using cuticle removers, as heretofore con- '6 structed, it has been necessary periodically to dip the instrument into the solution being used. This disadvantage is overcome by means oi the present inventionaccording to which the cuticle remover is provided with ar reservoir for the solution in question, the supply of the solution to the end of thefdevice being controlled by means of a suitable valve.

The valve may be of any suitable form, but is preferably spring-controlled and adapted to be operated by a ringer operated plunger which is adapted to open the valve and allow the fluid to flow drop by drop.

`The instrument has been illustrated by way of example in the appended drawing wherein Fig. 1

is a view of one form of the instrument, Fig. 2

is a section and Fig. 3 is a section showing operation of the same; Fig. .4 is a sectional view of a modification.

The device comprises a tube or barrel of metal l, the material sold under the registered trademark Balrelite, or any other suitable material. The lower end of this tube, which is intended to receivel the solution, is of reduced diameter and is screw-threaded externally to receive a removable tip-2 which may bemade of the same or a different material to the tube itself, this tip being shaped, lif desired, to the usual form of a cuticle remover, i. e. flattened on the underside and slightly curved at its end. The tip is provided with a central bore 3 having an orice, say, one quarter of an inch -in diameter. The upper end of the tube is screw-threaded to receive a cap e which screws into the tube and is provided with g a central bore 5, in the upper end of which is located` a button or plunger 6, the edge oi the bore being spun over shown in 7, or otherwise arranged, to form a stop against which a flange 8 on the plunger 6 abuts to limit the outward movement of the plunger. Attached to the underside of the plunger is a rod 9 which passes through a hole 10 in a suitable washer or disc 10 in the cap which thus forms a bearing for the rod. A compression spring l1 is disposed between this disc and the plunger to return the plunger to its 5U outer position, and the inward movement of the plunger 6 may be limited for a purpose hereinafter explained either by reason of the coils of the compression spring 11 abutting against one f another or by reason ci the amount by which '55' the plunger projects beyond the cap, the linger in the latter case coming up against the 'cap to prevent further inward movement oi the plunger (as shown in Fig. 3).

TheA hole 10 through which the plunger rod .4.,

slides is preferably a good t around the plunger rod so as to prevent the solution in the tube leaking-past the same while allowing air to pass.

suitably disposed within the. tube. is a further web or disc 12, preferably provided with recesses 13 around its edge to allow a free flow of solution past this web. l This web -forms a bearing furthe valve spindle` 14, which, at its upper end, is provided with a head 15 against which the lower end of the plunger rod 9 bears. The valve proper comprises. a conical member 16 on the lower end of the valve spindle whichv co-operates with a conical seating in a web 17 across the lower end of the tube, the conical surfaces being so disposed that the valve spindle .has to be pressed down to open the valve. The valve proper is extended on its further side also as a long cone 18 which is located in the bore in the tip 2 and may be arranged to close the exit oririce when the valve is open, if desired;

A compression spring 19 is arranged between the web in thetube and the head on the valve spindle to keep the valve normally closed.

To ll the device, the cap is lremoved and the solution poured in, the valve duringV this opera-v tion being. kept closed. The cap is then screwed on again, and when it is desired to use the device, the plunger is depressed by the finger to allow a small quantity of the solution to flow into the tip from whence it passes to the linger nail. .As soon as the pressure is released, the valve will close, and it will be seen that by limiting the inward movement ofthe plunger, as above described, it can be ensured that the valve will not open too far. f

Many modifications may be made in the above described lconstructional form oi this invention.` Thus, for example, in the'inodincation of Fig. 4 the tip 2 is screwed on to the lower end of the tube and is bored out to receive a thin tube 20 which projects from the lower end of the tube l. The bore 3 in the tip communicates with the edge of the tip by means of a line passage 21. The supply of the solution from the barrel to the tip is controlled by a needle 22 which projects down the centre of the solution receiving tube and also the une tube. This needle is carried by a cap 23 which screws on to the upper end of the tube, the needle being secured to a small springcontrolled plunger 24 carried by the cap 23 so that by depressing the plunger with the ringer los `the needle may be made to move up and down in the thin tube.Y A compression spring 25 is arranged between the plunger and a shoulder 26 in the cap and a rubber washer 27 is arranged on the underside of the shoulder to render the joint between the tube and the cap air-tight. With the cuticle remover, according to the present invention, it is merely necessary to depress the plunger knob to cause a drop of solution to flow down the bore in the tip on to the nail, after which the cuticle remover is used in the usual manner. This device may be filled by unscrewing the cap 23 partly only and introducing the solution by a hole 28 in the threaded portion of the barrel.

It will thus be readily appreciated that the cuticle removers, according to the present invention, will be very simple and easy to use and will furthermore obviate the necessity of frequently dipping the cuticle remover in the solution.

In a furthermodication, the thin tube 20 above referred to may be provided with line holes 29 to facilitate the flow of the solution. Again, any other form of valve, which will allow the solution to be fed drop by drop to the tip, may be employed.

Having now fully described our said invention, what we claim and desire to secure by Letters Patent,is:
