BRUSH AND HOLDER ATTACHMENT FOB EBASERS.

Application filed September 26, 1921. Serial No. 503,223.

To all whom it may concern: it can effectively be employed without tiring Be it known that I, JENs P. NIELSEN, the hand of the user. Still further and also citizen of the United States, residing at Chimore detailed objects will appear from the cago', Illinois, have invented certain new and following specification and from theaccomuseful Improvements in a Brush and Holder panying drawings, in which Attachment for Erasers; and I do hereby Fig. 1 is an elevation of a disk eraser declare the following to be a full, clear, and equipped with my invention, with dotted exact description of the invention, such as lines showing a desirable position of the will enable others skilled in the art to which hand of the user when the brush is being it appertains to make and use the same. employed.

My invention relates to pencil and ink Fig. 2 is a rear elevation of the same emerasers and in some of its various aspects bodiment showing the same as it appears aims to provide simple, inexpensive and unwhen supported on a side of the frame of a usually effective means 101' equipping such standard typewriter.

the efiective manipulating of the brush In accomplishing the purposes of my inwithout requiring an undesirably tight vention after the manner of the accompanygrasping of the same by the hand of the ing drawings, I substitute a special form of user. With this latter purpose in mind, my metal attachment for one of the disks or invention aims to provide an eraser attachspool ends as commonly employed at oppoment having a holder portion adapted for site sides of an ordinary disk eraser. -Tl1is supporting the complete appliance in a 'despecial attachment consists of a metal plate sirable position, andalso adapted for over- 1 having a pair of arms diverging from hanging and engaging one portion of the each other. at an acute angle, the metal plate hand of the user while permitting other porfor this purpose being desirably secured. to tions of the same hand to be employed efthe eraser 2 by a hollow shaft or-rivet 3 exwill be conveniently disposed for facilitatment, namely one in which the brush extends fectively in grasping the appliance and in tending through a corresponding axial bore exerting the desired pressure on the brush in thedisk and clinched over .a'plain fiat when using the latter. washer i disposed at the opposite side'of the More particularly, my invention aims to disk. provide a brush and holder attachment for One of the arms 5 of the forked metal erasers which will maintain the brush and plate as thus attached to the eraser'is dethe holder portions in a desirable relative sirably recurved upon itself soas to present disposition and which will permit the entire its tip 6 towardsthe' axis of the eraser and attachment to be rotated freely about the so as to afford a hook for supporting the axis of an eraser when the latteris of the complete appliance after the general mandisk or so-called circular type. It alsoaims ner of the U. S. Patent #:1241714, issued to provide a simple, cheaply constructed November 27th, 1917 to Walter B. Pershing. and firm mounting for the brush proper and The'other arm 8 is equipped for'supporting aims to dispose the brush in a plane in which a brush and for this purpose desirably has its outer end 9 bent substantially at right angles to the general plane of the arm and end overhangs the edge of the eraser disk, thereby affording a suitable bottoming support for a ferrule or socket 10 carrying the brush proper. This bri'isl'i-l'i'oldin'g socket desirably is flattened to correspond substantially to the flattening of the eraser disk and desirably has an integral bottom 11 equipped with a pair of perforations to permit the entry of corresponding fingers 12 formed from the bent overhanging end 9 of the said arm 8 as shown in Fig. 5. In assemling the parts, these fingers are bent over against the bottom of the socket so as to clamp this bottom against the arm end 9 as shown in Fig. 4-, thereby firmly securing these parts to each other. Then the bristles 13 of the brush are slipped into the socket and secured in position by cementing or the like, after the usual manner.

With the appliance thus constructed, it will be obvious from Figs. 2 and 3 of the drawings that the entire appliance can readily be supported clear of the desk or table of t e user by simply snapping the hook 5 over the frame portion 15 of an ordinary typewriter, thus preventing both the eraser and the brush from picking up It will also be evident by mounting the brush so that it will slope upwardly when the appliance is thus supported, the brush s hand when the applicance is be ing grasped for erasing purposes. So also, the pivotal mounting of my attachment on a disk eraser permits the eraser proper to be rotated when desiredfor bringing fresh portions of the same into operative positions.

VVhen the brush portion of the appliance is to be used, the appliance is desirably held as shown in Fig. l or with the tip of the users thumb under the. hook so that the hook overhangs this thumb tip and affords a stop for the thumb. Owing to the angular diverson of the hook from the arm carrying the brush, such a position of the hand readily brings the fore finger of the same hand opposite the eraser directly back of the hook and brings the middle finger of the hand in substantial alinement with the brush-holding arm. The appliance can, therefore, be grasped with the thumb and said two fingers and with the middle finger pressing fiatwise against one side of the socket holding the brush,

an effective leverage for using the brush.

substantially into the same plane with the further described eraser, I make it easy for the users hand to reach the said socket in this manner, while also improving the appearance of the appliance as a wl'iole c t However, while I have illustrated and described my brush-holding attachment as employed on an eraser of the disk type and as pivotally mounted on the eraser, I do not construction and arrangement herein disi closed, it being obvious that the same might be modified in many ways without depart ing from the spirit of my invention or from the appended claims.

shows another embodiment in which the as in the other figures.

I claim as my invention 1. An eraser and brush combination, comprising a disk eraser, a pair of arms extending substantially radially eraser and at an acute angle to each other,

the said combination and also disposed for overhanging the thumb tip of a hand grasping the eraser, a brush socket carried by comprising disk eraser, and a combined member being disposed for engagement by a finger-tip of the same hand.

3. 'he combination with a disk eraser, of a carrier spool on which the eraser is rotatably mounted, one head of the spool having a pair of arms extending radially of the spool at an acute angle to each other,

' named bent ing the said bent arm portion and equippe with perforations, bent arm portion has fingers projecting through the said perforations and bent against the ferrule bottom to clamp the ferrule to the said bent arm portion.
