'- 4 Claims. (Cl. 120-108) This invention relates to improvements in desk,

, sets adapted for use on a desk to hold a writing instrument in position for use and the purpose *of the present invention is to provide a novel device in which a pencil or other writing instru- 5 ment is held magnetically so that it may readily be removed from or replaced in its normal supported position.

In desk sets of the type heretofore commonly in use, writing, instruments have usually been held in place on a supporting base by engagement'with a socket or other holding device mountved on' the base. These holding devices have required'the movement of the instrument along a precise path in moving it into or out of engage- 'ment with the part by which it is normally held on the base and all such devices in common use have depended upon gravity or spring pressure to hold the writing instrument in place, so that some attention has been required to remove or replace the writing instrument and it has not always been held securely against accidental removal. s V

-- The principal object of the present invention is to overcome the above mentioned difliculties,

and others, by providing an improved desk set in which the-writing instrument is held by novel magnetic means in a position to be conveniently engagedby the hand of the user. A further object is to providea desk set comprising a base having embodied therein a permanent magnet a'rranged toattract a magnetizable element carried by the writing instrument, the magnet and the magnetizable element having cooperating surfaces adapted to cause the instrument to be supported in a convenient inclined position with re spect'to the surface which supports the desk set. Another object is to provide a desk'set comprising a base, formed preferably of molded insulating material and havingembedded therein a pera 40 manent magnet arranged with-its pole faces at an angle to the horizontal to attract a magnetizable element carried by a writing instrument, "which element inay preferably be in the form of an annular tapered tip through which the writing point of the instrument projects. Still another object is to provide a desk'set comprising a; non-metallic base having adepression located over the pole faces of a permanent magnet embedded in the base, the pole faces being positioned at or near the surface of the depression and being adapted to attract a magnetizable element, ipreferablyin the form of an annular tapered tip which fits over and formsa part of a writing instrument. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawing in which onefggnbodiment is illustrated. In the drawing,

Figure 1 shows a perspective view of the improved desk set;

Fig. 2 shows a to plan view of the supporting base of the desk set illustrated in Fig. 1; and

Fig. 3 is a vertical section taken on the line 3--3 of Fig. 2.

As illustrated in the drawing, the invention" like and preferably having applied thereto a layer l I of paper, feltor other materialadapted to protect the desk surface. The base In is generally rectangular in form and has an outer surface'lu which converges upwardly from the bottom of the base with roundedcorner portions at the front. The upper surface, llJ is horizontal and has formed therein two recesses Ill which form re- I ceptacles for paper clips, rubber bands or other articles. Between the two receptacles I0 the base is provided with an upwardly extending instrument supporting projection 1. The rear wall of this projection is inclined upwardly in the same plane with the rear portion of the outer wall lo of the base and the top surface ll) of the projection is inclined downwardly and forwardly toward the front edge of the top wall of the base, terminating in a curved surface I 0 which merges with the front portion of the inclined outer wall M The supporting projection w is provided with a depression Ill in its top surface which is relatively wide at its rear end, as shown in Fig. 2, and which tapers toward a'point at its forward end, so that it conforms generally-to the shape of the end portion of a pencil or other writing instrument l2 which is adapted to be supported whilein engagement with the recess lll as shown in Figs. 1 and 3. The forward end of the surface of the depression Ill may be curved into a horizontal plane or slightly in a reverse upward direction, as shown in Fig. 3, to facilitate the posistem portion [2 which has its greatest diameter adjacent it lower end. The lower extremity of the stem portion is tapered in the opposite direction to the taper of the upper part, as shown at l2, and has fitted thereover a correspondingly tapered metal tip I3 formed of magnetizable material, such as iron or steel, which may be plated to give it an attractive appearance. This tip portion I3 is in the form of a truncated cone, being open at its lower end to permit the projection of the writing point M which may be the lead of a pencil, as illustrated, or the writing point of a pen or the like. The stem portion of the writing instrument I2 is preferably formed of non-metallic insulating material and the part 12 is formed to fit the metal tip [3 so that the outer surface of the tip is flush with the adjacent outer annular surface of the part l2 For the purpose of holding the pencil or other writing instrument l2 in position in the depression 10- of the base, the base is provided with a permanent magnet l5 which is of horseshoe shape. as shown in Fig. 3, being embedded in a block l6 which is inserted in a'cavity I formed in the base and extending upwardly from the bottom thereof into the projection Ill After being thus inserted, the block l6 may be held in place by cement or the like or by the subsequent application of the underlying protective sheet II. The magnet 15 is so positioned that its pole faces 15 are exposed in the plane of the upper inclined surface l6"- of the block l6, which may preferably be formed of molded plastic insulating material of such shape that it closely fits the cavity I0 from which it may be removed, if desired, for the purpose of replacing the magnet.

The pole faces Ili of the magnet lie beneath a thin layer W of the material of which the base is formed, this layer constituting the bottom wall of the depression I0 The pole faces of the magnet are thus protected from moisture and the like and the layer 10 is preferably thin, for example, one thirty-second of an inch or less, so that the gap between the pole faces and the metallic tip iii of the pencil will not seriously diminish the attractive force of the magnet upon the metallic portion of the pencil. The metallic tip l3 should preferably be of such length that it bridges the two pole faces when it is seated in the depression lil It will be observed that the magnet I5 is 50 mounted in the removable block l6 that the pole faces I5 occupy an inclined plane which extends upwardly and rearwardly from the forward part of the base to correspond with the upward and rearward inclination of the top surface of. the supporting projection H) of the base, thus holding the pencil l2 in a convenient and attractive inclined position from which it may readily be removed by the user and to which it may with equal facility be returned. The inclination of the pencil I2 is produced in part by the tapered form of the metallic'tip l3 and the inclination of the pole faces [5 may be such as to cooperate with the taper of the metal tip to hold the pencil in the desired position.

With this construction, the pencil or other writing instrument I2 is securely held in place on the After use, the pencil or other writing instrument having the magnetizable tip portion may be readily replaced in position on the base without serious attention on the part of the user and without the necessity of great precision in returning the pencil to its position, since the depression ill is so formed as to actas a shallow socket in guiding the lower part of the pencil to a position where the metallic tip l3 will be positioned opposite the pole faces l5. The curvatures of the surfaces of the depression l0 will assist in locating the pencil properly on the base but even though the metallic tip is not positioned with precise accuracy over the pole faces the attractive force will be sufiicient to hold the pencil securely on the base.

Although one form of the invention has been shown and described by Way of illustration, it will be understood that it may be constructed in various other embodiments coming within the scope of the appended claims. The term pencil, used in the claims, is to be interpreted as including within its scope pens and other writing instruments.
