. Patented June 30, 1936 PATENT oFFics MANICURE APPLIANCE Anna. Hunter, ne Schuber, Berlin, Germany Application April 18, 1935, Serial No. 17,010

Germany July 26, 1934 Manicure appliances are known in which a liquid preparation stored in a hollow barrel is fed to the tool joined to a piston mounted to slide in the hollow barrel, and thus to the finger-nail, 'by

pressing back the piston. The movement of the piston is at the same time not restricted in the upward direction, so that if the piston is removed from its seat, the oil fiows out unhindered, and in this way the liquid reservoir can be completely emptied in a short time.

In addition, manicure appliances have been made known in which the liquid is intended to be fed to the nail through a capillary opening. The capillary opening is in this case closed by a conical valve the operative devices of, which are outside the actual apparatus, so that the handling of the tool is very complicated.-

I The present invention eliminates this disadvantage by placing all the essential parts in the interior of the apparatus and by having the liquid preparation fed through the longitudinal bore of an inserted member in the form of a piston to the finger-nail that is to be treated, the said preparation being fed automatically and in small quantities.

In the accompanying drawing the object of the invention is shown in one example of construction.

Fig. lshows a longitudinal section of the tool.

Fig. 2 shows the inserted nib serving for the pushing back of the cuticles.

Fig. 3 shows one of the two hollowed-out nib manicure sticks.

Fig. 4 shows a further formation of the con- 85 tainer.

Fig. 5 shows a further formation of the insertion piece, for pushing back the cuticles.

In accordance with the drawing there is a rubber bladder 2 in the tube whichbladder 2 sucks in oil when the two-armed lever 3 is swung out, after the fashion of a fountain-pen reservoir; In the tube I there is also an inserted slideway member 4, screwed-in,.fitted with two borings 5 and.6 of different diameters. Over the boring 5 is placed the said rubber bladder 2; at the front is screwed-on a cap I, also fitted with a longitudinal boring, which cap encloses a colla! 8 of a piston 9 which it presses against the cap 'I by means of a spiral spring l0 mounted in the boring 6. The piston 9 is also provided with a longitudinal boring i I in the direction of the interior of the instrument and a longitudinal boring l2 in the other direction. In the latter boring there are fitted two half sticks i 3 and M which are provided with grooves l5 and I6 for feeding the oil.

Between the two half sticks is mounted'the actual manicure implement H, which is advantageously of the shape shown in Fig. 2, in which case there is the part IB which is pushed into the instrument and the part i9 which is advantageously '5 curved for pushing back the cuticle and if desired slit in the style of a pen-nib. The side projections 20 are intended to ensure that the "nib lies against the piston 9 when in use. when the instrument is being used, light pressure on 10 the part of the finger-nail that is to be treated causes the piston 9 to be pressed back, after the spring tension has been overcome, in the style of a pump piston. In this way a certain quantity of oil reaches the boring i2 and 15 thus passes through the grooves l5 and I6 to the pen tip [9, and'so to the finger-nail. The fiow of oil is effected as often as the instru ment is pressed on to the nail. When not in use .the instrument is closed by a cap 2|, pushed or 20 itself would act as the reservoir for the liquid,

the barrel then having to be for preference transparent at a suitable spot for the purpose of seeing how much liquid the reservoir holds from time to time. The instrument can be divided into two parts by a longitudinal partition 24-as shown in Fig. 4. In the smaller longitudinal container 25 a nail file 26 could then be kept. In accordance with Fig. 5 the .nib for pushing back the cuticle can also be formed as follows: instead of the holder sticks l3 and It, the inserted piece 21 itself could be used for pushing back the 40 cuticle. The other stick 28 then serves as support for the piece 21 and is fitted with a channel I 29 for the oil feed. In order to avoid the formation of a vacuum in the container, the piece 21 has a perforation 30. Through this perforation and the adjacent channel 29 air can pass unhindered into the container when the liquid in the reservoir is gradually used up.

I claim:

1. A manicure appliance comprising a barrel 50 member adapted to contain a liquid preparation for treating the nails, a slideway member closing one end of said barrel member, a cap having a central bore, screwed onto said slideway member,

a pistonadapted to slide in said slideway member 65 r 2 a and in said cap, an abutment carried .by said piston adapted to limit the movement of said piston between the 'slideway member and the cap thereof, spring means tending to push the abut ment on said piston against the cap, a tool at theouter end of the piston for treating the nails, pressure on said tool causing the piston to slide into the slideway member and pump some of the liquid contained in the barrel member through a. longitudinal bore in said piston to the tool.

2. A manicure appliance as claimed in claim 1, comprising a slideway member having a part of its bore enlarged, a piston sliding in said slideway member, and a spring mounted in. the enlarge'd bore of the slideway member tending said gripping members having channels on their inner faces for the passage of the liquid from the longitudinal bore in the piston to the tool.

4. A manicure appliance as claimed in claim 1, comprising a bladder mounted inside the barrel member and connected to the slideway member, said bladder being adapted to hold the liquid preparation for treating the nails.
