VTo @ZZ whom it may couoeimf Be it known that LJosErri MAY, a citizen of the German Empire, residing at Frankfort-on-the-lifain, Holzsraben 2,have invented certain new and useful "Improvements in Pen Cleaners, of which the following is a full, clear, and'exact description, refe-rence being had to the-accompanying drawing and to letters of reference marked thereon.

MyV invention relates to a new pen-cleaner. F or pen-cleaners, material of different kinds for dry and wet use has heretofore been proposed; but these materials were not satisfactory for wiping the pens and did not accomplish their purposes. In some cases such materials clog the pens with libres, in consequence of the fibrous nature of said material, or in the case of wet cleaners, a very speedy ruinof the pens by rust has resulted from their use. To the aforesaid class of dry wiping devices belong for ef;- ample, felt, soft leather and the like while the class of wet wiping devices` includes, for instance a sponge fitted in a water chamber.

The nature of the present invention consists in the use of a sponge-rubber for dry wiping of the pens.

F or the purpose referred to, this material is fitted specially owing to its natural qualities. Sponge-rubber is smooth, soft, slippery and porous. It does not unravel, removes the ink and the residues smoothly and completely from the pen and does not suck up or absorb the ink, like felt, soft leather or otherV fibrous materials. The ink and the ink residues wiped from therpen are loosely accumulated upon the surface of the sponge-rubber and are therefore very easily 0' washed out and removed thus making it 4 easy to maintain the cleaner in a serviceable condition. In consequence of its smooth and slippery-surface the sponge-rubber preserves Vtlie pens against undue wear in cleaning and wipes them completely dry. Moreover they sponge-rubber is further advantageous, because it does not clog the pens with-libres, which cause imperfections in subsequent writing with the aid of said pen.

The accompanying drawing shows two examples of the new pen-cleaner one of which is for use by hand and the other of which is capable of use by hand or as a standing pen-cleaner upon a writing table or desk. In said drawing- Fig. 1 is a section of the pen cleaner for useby hand, and

. Fig. 2 a top view thereof. l y

The pen-cleaner, in the form shown in Figs. l and 2,'jconsist's of two arched plateshaped parts` a, al, each of which constitutes a body and are covered on the inside with sponge-rubber and which have their convex surfaces toward each other are held together by an elastic member. The annular slit formed in this manner for cleaning and wiping the pens may be compressed by the plateshaped parts at any place, or may be caused to spread or gap at a point opposite to the point at which pressure is exerted to press the plate-shaped parts a and a toward each other. The execution of the pressure results in an axial direction.

Instead of the central fastening means, a tension chain may be provided, which tension chain is stretched around the spongerubber so as to extend about the foot of the cupola. The body itself may be manufactured in any convenient manner and of every suitable material and it may simultaneously serve other purposes, for instance, as a letterpresser or the like; it may also beused for advertisements.

The yielding, universally pliant, soft and smooth slippery mass of the sponge-rubber, makes it possible to thoroughly clean the pens or the like with the least wear thereon and with the danger of injuring the saine or of clogging or otherwise harmfully effecting said pens or the like reduced to a minimum. The sponge-rubber material, because of its easy exchangeability, is repeatedly available and is easily cleaned by washing.

Having thus described my improved pencleaner of sponge-rubber, it will be seen, i

that it has many advantages over those theretofore in use. lts cost is very little including the sponge and it is very durable.

claim as invention:

1. A pen-cleaner comprising a pair of elements lying in surface engagement with each other, at least one of said elements being of sponge-rubber and means for resiliently fastening said elements together at an intermediate point whereby the surface engagement of said elements is maintained and the edges thereof are free and disconnected to permit a pen to be inserted between said elements and subjected to the cleaning action of the sponge-rubber.
