Jan. 12, 1954 G. E. HooPER FINGER MOUNTED ERASER Filed March 3, 1952 L; /g mvENTOR ATTORNEY Patented Jan. 12, 1954 UNITED STATES PATENT OFFICE FINGER MOUNTED ERASER Glenn E. Hooper, Springeld, Mo.

Application March 3, 1952, Serial No. 274,547`

6 Claims.

This invention relates to a novel construction of eraser and eraser mounting and more particularly to a holder adapted to be detachably applied to and worn on the linger of the writing hand and which forms a support for a pencil eraser and a typewriter eraser and whereby the erasers are conveniently positioned relatively to the supporting nger so that either eraser may be conveniently used for accomplishing an erasure.

More particularly, it is an aim of the present invention to provide a finger supported multiple eraser holder constituting a finger stall adapted to be worn on a ringer of the writing hand for supporting the erasers and including means enabling worn erasers to be removed and replaced.

A further object of the invention is to provide a multiple eraser adapted to be worn on one of the fingers'used to hold a pencil including an eraser holder for supporting a pencil eraser in a position enabling it to be conveniently used by merely bending the nger on which the holder is mounted.

A further object of the invention is to provide a multiple eraser having an eraser element for making typewriter erasures and which multiple eraser may be worn on a ringer by a typist While typing so that the eraser will be constantly available for making erasures of typewritten letters.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is a plan view looking toward the inner side of a multiple eraser;

Figure 2 is a similar view looking toward the outer side thereof;

Figure 3 is an enlarged cross sectional view of the multiple eraser taken substantially along a plane as indicated by the line 3--3 of Figure 2;

Figure 4 is a longitudinal sectional view taken through a portion of the eraser and illustrating one of the erasers and its mounting, taken substantially along a plane as indicated by the line 4-4 of Figure 3;

Figure 5 is a similar View taken substantially along a plane as indicated by the line 5-5 of Figure 3, showing the other eraser and eraser mounting;

Figure 6 is a plan View of the holder of the typewriter eraser;

Figure 7 is a plan View of the holder of the pencil eraser;

Figure 8 is a longitudinal substantially central sectional view of the holder of Figure 7, and

Figure 9 is a side elevational view of the pencil eraser which ts the holder of Figures 7 and 8.

Referring more specifically to the drawing, the multiple ringer mounted eraser in its entirety is designated generally I0 and includes a nnger tip engaging stall, designated generally II, which is adapted to fit snugly over the tip of a iinger F, as illustrated in Figures 1 and 2, to enclose the tip of the finger inwardly to beyond the innermost portion of the fingernail. The stall I I is preferably formed of rubber and includes a portion I2, constituting more than one-half of the finger tip stall II, which is formed of hard rubber and is preferably lined on its inner side with a thin layer of sponge rubber I3. The remaining minor section I4 of the ringer tip stall II is preferably formed of a flexible elastic rubber and extends longitudinally of the stall, substantially from endto-end thereof.

An eraser holder, designated generally I5, includes a transversely arched base I6 which is curved to conform to the curvature of the stall portion I2 and is embedded therein, as illustrated in Figures 3 and 5. The eraser holder I5 is provided With an outer part Il which is secured to the outer convex side of the base I6, in any suitable manner. The outer part I'I is narrower than the base I6 and is provided with outwardly extending inwardly turned side edge portions, which are spaced from the side edges of the base IB and which form internally recessed flanges I8. The outer part Il, intermediate of the flanges I8, is provided adjacent the ends thereof with transversely extending recesses I9 and 19a. The outer part I'I is provided with an intermediate preferably circular recess 20 disposed between the end recesses I9 and Illa.

An elongated block of rubber or other suitable material for making pencil erasures and constituting a pencil eraser, designated generally ZI, is slidably iitted into the holder portion I1 so that an inner or base portion 22 thereof is engaged between the flanges I8 which prevents outward displacement of the eraser 2| away from the holder I5. The inner surface of the base portion 22 is provided with transversely disposed tits 23 and 23a near the ends thereof and an intermediate tit 24. When the eraser 2| is applied to the outer holder section Il by being slid longitudinally into the channel of the holder section I'I from either end thereof, the tit 23a will seat. in the recess I9a, the tit 23 will seat in the recess I9 and the tit 24 will seat in the recess 2B when the eraser 2I has reached a fully applied position, as illustrated in Figure 5. The three tits and three recesses are made of different sizes or shapes so that each tit will only t one of the recesses. This may be accomplished in reference to the end recesses I9 and ISa as by making one of the recesses longer and narrower than the other recess, as illustrated in Figure '7 and by making the tits 23 and 23a of a conforming size and shape. t will thus be seen that the eraser 2| will be eiiectively held in the holder I5 after being applied thereto, as previously described, but may be forcibly removed therefrom and replaced after the eraser has been substantially worn out. The eraser 2I is provided with an outer erasing face or surface 25 which is transversely inclined, as seen in Figure 3 so that the eraser ZI is substantially thicker at one side thereof than at its opposite side.

A second eraser holder, designated generally which is embedded in the stall portion I2, and an` outer section 28 having the curvedsideedgesforming flanges 29, corresponding tothe portion I1 and flanges I3, respectively. :Thezportion 23, as best seen in Figure 6, .is provided. with longitudinally spaced dissimilarirecesses 30,"30a and 39h. An eraser 3|, formed of a .material which is effective for erasing typewritten letters and constituting an r.elongated block, has a base portion provided with vlongitudinally spaced dissimilar tits 32, .32a and 32h. The eraser 3| is beveled on one side thereof at one of its ends, as seen at 33. 'Iheouter portion 28 of the holder 2t has a similarly beveled end 34 and the base is similarly beveled at the saine end, as indicated at Eea. The typewriter eraser 3i is inserted lengthwise into a channel formed by the outer portion 28 and its lianges 29 and the tits 32, 32a and S2?) Wlll snap into the recesses Sil, 39a and 39h when the eraser 3| is ina properly applied position and due to their dissimilar shape and disposition are incapable of iitting-other than the recesses which conform in shape thereto. The base portion 35 of the eraser 3| nts snugly in the recessed inner sides of the flanges 29, as illustrated in Figure 3, so that the eraser 3| is effectively held in an applied position but may be pried from the holder 2t and replaced when worn out.

The multiple finger mounted eraser It vis preferably mounted on the middle ngerof the writing hand. Figure 2 illustrates the outersi-de of this middle linger E and it will be noted that the hard rubber stall portion I 2 engages the outer part of the tip of thennger F. The eraser 2i disposed along the outer side of the nger F and adjacent the outer edge of the ringer. Assuming that the-finger F constitutes thev middle iinger of the righ hand, the pencil eraser 2| is disposed near the side of the middle ngerdisposed remote to the index finger, not shown. The inclined surface 25 of the eraser 2| slopes away from theouter or back side of vthengerl and is thus disposed so that it will normally not be in Contact with a piece of paper `when the middle nnger is used to assist in supporting -a pencil during writing. However, by a very slight movement or the nnger F from a writingposition, the eraser surface 25 may .be positioned in contact with the paper for .accomplishing an erasure.

Figure l shows the inner side ofthe middle nnger of the right hand with they multiple nnger mounted eraser disposed thereonand illustrating the location of the typewriter eraser 3| adjacent the tip or the finger near the side thereof remote to the index finger, not shown. It will also be noted that the eraserJSI is Vdisposed at a slight angle to the longitudinal axis of the'nnger and the beveled portion 33 thereof'is at the inner end of the eraser and constitutes a part of its inner side,'so that the eraser v3| will not interfere with the use of the finger F fortyping. Thus, the multiple finger mounted eraser IIl'may be wornon the middle finger of the right hand while typing and by slightly turning the lingerV F, the eraser 3| may be disposed in a proper position for erasing one or more typewritten letters or an entire word or more. .It will likewise be obvious that the elastic stall portion, I4 Will effectively cause the finger stall II to grip the tip of 4 the Vnger F to-retain thestall in V*a correctly applied position thereon whiletyping or writing longhand and Will maintain the erasers 2| :and 3| in a correct position as illustrated in Fig- --ures 1 `and2 for most convenient use.

"The stall portion I2, I3 is preferably provided '.with Ya..plurality of Ventilating apertures 36 as illustrated in Figures 1, 2 and 3.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined bythe appended claims.

I claim as my invention:

1. A finger mounted erase-r comprisinga flexible nger engaging stall, an eraser element, and connecting means demountably connecting the eraser element to the linger stall for supporting .the eraser element on the outer side of the'nger stall, said nger stall including a hard rubber portion to which the connecting means is secured and an elastic portion adapted to grip the linger for maintaining the fingerr stall thereon.A

2. A ringer mounted eraser as in claim l, said eraser element constituting an elongated block disposed longitudinally of the ringer stall and having a transversely inclined outer face.
