MAGNETIC HOLDER FOR PENCILS Filed Aug. 22, 1950 INVENTOR. ALBERT A- MARKowlTz BY Q array/m Patented Apr. 29, 1952 UNITED STATES PATENT OFFICE MAGNETIC HOLDER FOR IENCiLS Albert A. Markowitz, Bronx, in Application August 22, 1950, Serial No. 185,733

3 Claims.

other utilitarian relations in combination with the pencil or the like.

According to the invention as preferably carried out to provide a holder for a pencil, pen, brush handle or other article of slenderized elongate kind, the device of the invention incorporates a sleeve-like housing for embracing said article ,and girthwisely "gripping the same, said housing being elongated in the direction of length of said article and carrying a bar magnet.

A particular object of the invention is to provide a holder as last above described wherein the housing is endless in transverse section to establish a tunnel open from end to end of the housing, and wherein therefore the device has to be attached to and detached from the pencil or the like by relative endwise movement of the device and the pencil or the like. In the case of a pencil, for instance, the same durin use and as it is repeatedly sharpened and resharpened gradually becomes shorter and shorter, and equally frequently it is necessary or at least desirable to change the location of the magnetic device lengthwisely of the pencil; and, consequently, another special object of the invention is to provide a means, in part constituted of the material of the housing at said tunnel, and in part constituted by special shapings of different portions of the tunnel wall, whereby endwise relative movement between the device and the pencil is quickly and easily effected yet the device is dependably securely maintained in any position on the pencil to which it has at any previous time been last deliberately adjusted.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a pencil, and, attached thereto, one now favored embodiment of the device of the invention.

Fig. 2 is an enlarged end elevationof said device. 1 I

2 Fig. 3 shows said device side elevation.

, Fig. 4, a view similar to Fig. 2, illustrates anther now favored embodiment of the device of i the invention.

jFig. 5 shows the last-named embodiment in side elevation.

Fig. 6, also a view similar to Fig. 2, illustrates still another now favored embodiment of the device of the invention.

Fig. 7, this, too, a view similar to Fig. 2, illus- L trates yet another now favored embodiment of the device of the invention.

The magnetic holder, according to the first [form of the present invention illustrated in Figs.

.l to 3, is shown applied to a pencil l0 sharpened a its end l2 to provide a writing point l4, and having a metal ferrule l6 carrying an eraser [8 at its other end. From time to time. the end l2 of the pencil has to be resharpened and so made 29 shorter as the writing point I4 wears away.

' In all the forms of the device of the invention illustrated, the housing aforesaid, this as a whole designated 20 in Figs. 1, 2 and 3, 22 in Figs. 4 and 5, 24 in Fig. 6 and 26 in Fig. 7, fixedly carries a permanent bar magnet 28, the latter from end to end of constant cross-section as indicated.

"Said housing may be made so as to consist solely of a, one-piece sleeve-like structure incorporating throughout a single flexible material or a mixture of a plurality of flexible materials such as rubber, synthetic rubber, vinyl plastic or the like; or so as to be in the form of a pluralpart sleeve-like structure wherein a main outer "part of the housing is made of some relatively Tin'flexible or rigid material such as certain of j 'the plastics, metal, wood or the like, and wherein accommodation of a magnet 28 but also the aforejsaid article-embracing tunnel. Said tunnel is designated 20' in Fig. 2 and 24 in Fig. 6; and said seat, in which the magnet is permanently so'secured as by being" cemented or bonded therein,

:'is designated 20 in Fig. 2 and 24" in Fig. 6.

i In Fig. 2, the tunnel 20 is corrugatedlongitudinally of the housing 20, as shown at 20. These corrugations are illustrated as having their and valleys substantially duplicates in reverse, and with the ridges and valleys alternating and substantially uniformly spaced circumferentially of the tunnel.

In Fig. 6, the tunnel 24' is also corrugated longitudinally of the housing 24, as shown at 24*; these corrugations also having their ridges and valleys substantially duplicates in reverse, but with the alternating ridges and valleys arranged in four groups of a plurality of ridges each, with said groups substantially uniformly spaced circumferentially of the tunnel, and with the spacings between said groups considerably greater than the width of a group.

In Figs. 4 and '7, on the other hand, the housings, respectively designated 22 and 26 as already stated, are shown as having main outer structures, these respectively designated 22A and 28A and made of some relatively inflexible or rigid material; with each of said housings also having, in combination with its said main outer structure, an inner part in the shape of a flexible tube as aforesaid. These tubes, as shown in Figs. 4 and '7, are respectively designated 22Band 26B. The tube 223 is fitted in a cylindrical cavity 220 formed through and extending from end to end of the main outer structure 22A; similarly, .the tube 263 is fitted in a cylindrical cavity 260 through and extending from end to end of the main outer structure 26A; and each of these tubes is suitably secured in its said cavity as by being cemented or bonded therein.

In Figs. 4 and 7, it is the main outer structure 22A or 26A in which the seat, 22" or 26", for the magnet 28, is formed, while it is within the inner tube 22B or 263 that the article-embracing tunnel, 22 or 26, is formed.

In Fig. 4, the tunnel 22 is illustrated as corrugated as shown at 22. These corrugations, like the corrugations 20 of Fig. 2, have their ridges and valleys substantially duplicates in reverse, and with the ridges and valleys alternating and substantially uniformly spaced circumferentially of the tunnel.

In Fig. '7, the tunnel 26 is illustrated as corrugated as shown at 26. These corrugations are analogous to the corrugations 24 of Fig. 6, in principle of structure and operation. Here the alternating ridges and valleys are arranged in three groups of a plurality of ridges each, with said groups spaced circumferentially of the tunnel, and with the spacings between the groups considerably greater than the width of a group.

Any of said housings may have its exterior given any desired configuration,- or imprinted, lithographed or given any desired ornamentation or design, as, for instance, one applied directlythereto, or transferred thereto by decalcomania or the like, or carried by a paper sheet or other sheet with such sheet cemented or bonded to the housing.

When the magnetic device is to be attached to an article such as the pencil ID or the like, the device is readily endwisely slippable onto or detachable from the pencil and is also readily slippable along the length of the pencil as the latter becomes more and more shortened due to repeated sharpening. Yet the magnetic device will always dependably securelyretain the position to which it was last manually adjusted alongthe length of the pencil. Were the corrugations omitted, there would be diificulty in maintaining the grippability of the device relative to the pencil or the like, such that, on the one hand, deliberate slippage of the device along the length of thepencil is really free and easy,,yet accidenmaterial having an tal such slippage is combatted with an adequate amount of friction.

This objective of the invention is particularly well attained by spaced groups of corrugations as typified in Figs. 6 and '7. In arrangements such as these last, a temporarily abnormally increased ease of slidability may be deliberately set up by squeezing the housing of the device laterally against the embraced article, thereby abnormally to space a corrugation group from'said article without compensatingly increasing the frictional hold of some other corrugation group.

While in use the pencil I0 may from time to time be laid down, but always to be readily later located, even where the desk or table being worked at is covered with a multitude of papers, if in laying down the pencil the magnet 28 is brought suitably adjacent to a metal of the kind attractively reactive to a magnetic flux, such as iron, constituting or forming part of a larger object, such as a paper weight on the desk, or some other object larger than a pencil, on the desk, on an adjoining table or shelf, on a nearby wall, etc. Also, when wire .paper clips, pins and the like have become scattered among many papers on a desk or table, the pencil may be used as a handle for the magnet and the latter employed to pick claim as new, and desire to secure by United States Letters Patent is:

1. A magnetic holder for a pencil or the like, comprising an elongated body of non-magnetic axially extended tunnel adapted to havev the pencil extended therethrough, said body having a flat outer face, a bar magnet mounted on said flat face, said body being made of rigid material, and means within said tunnel to frictionally grip the pencil holding said body in a fixed position thereon, said means comprising a tube of resilient material fixedly mounted within said tunnel to have the pencil pass therethrough, and longitudinally extended flexible corrugations formed on the inner peripheral wall of said tube adapted to frictionallyv grip the pencil.
