ABRADER ATTACHMENT FOR WRITING INSTRUMENTS Filed April 15, 1936 Lib Patented Apr. 6, 1937 UNITED STATESFPATENT-OFFICE ABRADER ATTACHIWENT FOB, WRITING NSTRUIVIENTS WilliamC'fii ihrmanmIFort Wayne, InIL.

Application April 13,

Claims This invention relates to improvements in abrader attachments for fountain pens, pencils and similar instruments, and an object thereof is to provide an attachment adapted to be remov- 5 ably mounted upon a writing instrument or other suitable support and having an adjustable tongue one end portion of which is finely toothed on one of its surfaces to provide an abrading face, and the opposite end of the tongue being i shaped suitably to form a finger clip to hold the instrument and the device in a pocket by engagement of the clip over the front of the pocket as writing instruments having a clip are usually held.

Another object is to construct the attachment so there is provided a shelter in which the abrading face is concealedwhen the tongue is moved into one of its positions of adjustment. A further object is to provide an instrumen that is conveniently carried and readily brought into use for effecting erasures, polishing of various objects or for manicure purpose.

Other objects and advantages of the invention will appear in the following description. 05 An illustrative embodiment of the invention is shown in the accompanying drawing, in which:- Fig. 1 is a front elevation of a fountain pen provided with an attachment in which the invention is embodied, the abrader being in sheathed 30 position;

Fig. 2 is a similar elevation projected from Fig. 1 in a plane at right angles thereto; I

Fig. 3 is an elevation similar to that of Fig. 1 showing the abrader when in extended position 35 for use;

Fig. 4 is a side elevation projected from Fig. 3.; Fig. 5 is a fragmentary enlarged front elevation partly cut away showing the abrader in extended position; and

Fig. 6 is a side elevation projected from Fig. 5 showing the abrader in sheathed position, partially in section.

The illustrations show the invention as applied to a fountain pen of the usual construction having a barrel I provided with a removable cover cap 2 which when in place upon thebarrel shelters the nib 3 of the pen. Upon the lateral face of the cap is secured a sheath 4 preferably consisting of a metallic channel 5 that is secured 50 directly to the cap by any suitable means suchas prongs or rivets 6, and another channel that is fitted telescopically upon the other channel and forms a cover 1 therefor. The sheath thus formed is open at its top and bottom, and the opening 55 through the bottom is restricted to a limited 1936, Serial No. 73,994 (01. 120-39) extent by an inwardly turned ledge 8 hereinafter referred to.

Extending lengthwise through the sheath is disposed a longitudinally movable tongue 9 formed of spring metal that is slightly arcuate from one of its ends to the other. The middle portion of the tongue tends to bow outwardly, and one of its sides has made 'therein notches l0 and II (Fig. 5) adapted to receive a spring finger I2 that is formed by slitting the corresponding side wall of the channel 5, thus to hold the 'abrader in extended or sheathed positions accordingly as the tongue is adjusted.

The outer face of the lower portion of the tongue is smooth, and bears against the inturned ledge 8 so that the tongue is constantly pressed toward the inner channel 5 and thecap 2. Thus, the outer face of the upper portion of the tongue which is finely toothed to provide an abrading face I3 is held at all times from contact with the inner wall of the cover 1 which obviates injury thereto during adjustment of 'the tongue. 1

The lower end of the tongue preferably is coiled to form an enlargement l4 and constitutes a clip l5 when the abrader is sheathed for securing the pen and the attachment to the front of a garment pocket.

In use, the pen or other support to which the attachment is secured serves as a handle for manipulating the device, and the abrading face on the tongue is readily moved into extended or operating position by sliding the tongue upwardly in the sheath. Erasures from surfaces or polishing thereof is effected by stroking the surface where erasure or polishing is required with the abrading surface of the tongue and using more or less pressure manually applied to the back of posite end being formed to provide a clip for securing said attachment and instrument in a pocket.

2. An attachment for a writing instrument conatituted of a sheath having open ends and having means for attachment to .said instrument, said sheath having at one end an inturned ledge, and a normally arcuate spring tongue extending 5 through said sheath and longitudinally movable therein, one end portion of said tongue being toothed to provide an abrading face, the middle and opposite end portions or said tongue being smooth, having bearing relation with said ledge,

10 and constituting a cliptor securing said attachment and instrument in a garment pocket.

3. An attachment for a writing instrument and the like, a sheath having means for attachment to said instrument, a normally arcuate spring 15 tongue extending through and longitudinally movable in said sheath, and means to irictionally hold said tongue in diflerent positions of adiustment in said sheath, one end portion of said sheath being toothed to provide an abrading face, and

20 the opposite end portion .01 said tongue constituting a clip for securing said attachment and instrument in a garment poclret.v

' 4. An attachment for a writing instrument and the like, a sheath-having means for attachment to said instrument, and a normally arcuate spring tongue extending through and longitudinally movable in said sheath, one end portion of said tongue being toothed to provide an abrading race adapted to be projected into position for use beyond the corresponding end of the sheath or drawn into the sheath to be sheltered thereby accordingly as said tongue is adjusted.

5. In an instrument of the class described, a sheath and support therefor, a normally arcuate spring tongue extending through and longitudinally movable in said sheath, one end portion of said tongue having anabrading face, and means on saidsheath for frictionally holding said tongue in positions of adjustment in said sheath.
