Application April 1, 1950, Serial No. 153,478

7 Claims. 312-79) This invention relates to a dispenser for needles or like objects of magnetic material and particularly to a dispenser in which the objects are normally concealed and from which they are caused to project, for convenient removal at the time of use.

The invention is especially satisfactory for use with needles and will be first illustrated by description in connection with such use.

The invention provides a dispenser which is positive and effective, attractive in appearance, and characterized by a minimum of mechanical parts. The dispenser includes a magnetic carrier for the needles and construction that eliminates the usual spring or other mechanical contrivance required to return the magnetic carrier, after use, to the normal or rest position. Because the magnetic force extends from side to side of the carrier, the dispenser is effective in retaining the needles, against the force of gravity, even though the magnetic carrier itself is small.

Briefly stated, th invention comprises a dispenser for needle-like objects of magnetic material provided in an end portion thereof with an opening or openings to receive one or more of the objects, a magnetic carrier for the objects, and means for moving the carrier towards or away from the said holes. In the preferred embodiment, the invention comprises magnetic material disposed in the end of the case opposite the holes, so as to exert a pull at all times upon the magnetic carrier, this material being itself preferably a magnet and having a polarity of the upper surface opposite the polarity of the lower surface of the magnetic carrier. In a commercial form, the invention includes a handle or button for moving the carrier, the handle being a projection from the carrier which fits within a slot in the side wall of the case and serves to maintain the carrier in alignment, that is, at all times at approximately a right angle to the length of the case.

The invention will be first illustrated by description in connection with the attached drawings to which reference is made.

Fig. 1 is a perspective view of the needle dispenser with the needles projecting through the openings in the upper part of the case.

Fig. 2 is a sectional view on line 22 of Fig. 1 with the magnetic carrier at the down position, away from the discharge holes, so that the needles are completely concealed within the dispenser.

Fig. 3 is a sectional view on line 33 of Fig. 1.

Fig. 4 is a similar view of the construction with the carrier in the down position.

Fig. 5 are detailed views in perspective of the magnetic carrier and the bar of magnetic material.

Fig. 6 is a sectional view, ona reduced scale, of a modified form of the invention.

Fig. 7 is a sectional View on line 1--'| of Fig. 6.

There is shown the needle dispenser, with case it and a closure part l2 for an end of the case. This part is provided with spaced holes M which are slightly oversize with respect to the needles i5 and are, therefore, adapted to receive the needles. The closure part has substantial depth, from top to bottom, so that the holes serve as means for alining the needles.

A magnetic carrier or support I8 is disposed within the case. The carrier is mounted movably within the case, as by the handle 20 of plane sides fitting movably within the slot 22, so that the fitting of the handle 20 within the slot maintains the alinement of the magnetic support It at all times. This keeps the support in generally horizontal position as it moves upwardly and downwardly when the case is in vertical position. In general, this alinement maintains the magnetic support at approximately a right angle to the direction of extent of the needles [6 and of the length of the case I0. The handle carries a convenient form of button 24.

A bar of magnetic material 23 is mounted in the lower or closed end 26 of the case, in order to exert, upon the magnetic carrier, aiorce tending to pull the carrier towards the end of the case opposite the end provided with the holes.

It will be observed that the maximum distance between the position of the carrier Hi (i. e., the upper end of it) and the lower end of the closure part 22 carrying the holes M is less than the length of the needles. The lower end of the case, either with or without parts 28 or 36, constitutes a stop. This stop limits the movement of the carrier in direction away from the en provided with the holes, so that the needles, when the carrier strikes the stop, remain engaged in the holes. As a result the needles are disengageable from theholes l4 only when the needles are withdrawn outwardly through the holes.

One magnetic pole extends completely across the upper surface of the member I8, that is, from side to side. In the drawing, this is shown as the south pole S. As a result the magnetic force also extends from side to side oi the magnet. The force does not approach zero at any point on the upper surface, as would be the case if the left end of the magnet in Fig. 5, for instance, were one pole and the right end the other pole. In like manner, the second N pole of the magnet extends completely from side to side of the lower surface of the magnetic carrier.

The upper surface of the magnetic support or carrier is provided with an irregularity of surface to receive the ends of the needles.

In the preferred embodiment, the irregularity of the upper surface is V-shaped and s rovided at the lower 'partof'the l-shapewitha groove 30. This groove is somewhat oversize with respect to the ends of the needles to be received within the groove. In use, the sloping sides of the vshape of the upper part of themagnetic support direct the ends of the needlesintoth'e groovefifi. Here the ends are subjected to magnetic force not only from the material below the: ends of the needles, but also from the material constituting the sides of the groove 30. at one end with the carrier and, at the other end, is threaded to receive the button.

The bar of magnetic material 28 is suitably itself a magnet with the-polarity S of the upper surface opposite that of thepolar-ity of the lower surface of the magnetic support I8. This magnetism of the bar and dissimilarity ofpoles turned toward each other increases the attraction of the bar 28 for the support t8. The lowersurface of the bar is the N pole, it being understood that all poles of the carrier and bar maybe-reversed.

Fig. 6 and 7 have partscorresponding to those described but circular in form. This gives an article of the general appearance of a lipstick holder.

Thus, these Figs. 6 and 7 show case 34 provided with slot 4:1, magnetic material 36 at the base of the case, magnetic carrier 38, needle-receiving recess or irregularity 40, button 32, and the upper end closing part provided withholes-dfi suitably arranged annularly.

The magnetic polarity of parts 35and 38 are as stated above for members ltandZB.

The operation of the dispenser will be largely evident from the detailed-description that'has been given.

To charge the dispensena supply of needlesis introduced through theholes, to give suchan assembly as shown in-Figs. 4 and:6. In the normal position, the magnetic support l-lor .38 is drawn to the part 28- or 3%. This causes the needles to recede Within thefcase, as illustrated in Figs. 2 and 4.

When itis desired toproject the needlesabove the holes, so that one or more of the. needles may b withdrawn for use, the operator moves the button 24 or 42 manually: towards thedischarge end of the case, into the position shown in Figs. 1 and.3. After the needle or needlesthat are-to be used have been withdrawn by hand, release 01' the button 24 or 42 causes the carrier 1 8 01' 38 to move at once to the bar ofmagnetic material 28 or 36, with an accompanying. withdrawal of the remaining needles from view, withirrthe case.

As to materials of construction, the caselll. is formed of material that'is non-magneticunder the conditions of use. Suitable. non-magnetic materials are silver,..a1uminum,.and the common plastics such as those ofstyrene, ureaand .formaldehyde, phenol and formaldehyde, and, methyl methacrylate. The button 24 and the closure member l2 are suitably constructed-of the same material. 7

The magnet. 18- or. 33. is of. any suitable magneticmaterial magnetizedina conventional manner. Examples of: materials-that. may be usedafor this purpose are steehnickel, cobalt, and-those Stud 32 is integral alloys that are known to be magnetic, as for instance, the aluminum, nickel, and cobalt alloy known as Alnico.

The material of the bar 28 or part 36 must also be one which is magnetic, so that it may have atraction for the magnetic support l8 or 38. Best results are obtained when the bar 28 or part 36 is itself magnetized, in which case the upper part must be of'polarity oppositethat of the 'lower part of the carrier I8 or 38.

The dispenser of the kind described is compact, light .in weight, and, efiective and dependable for the purpose of retaining needles or like elongated magnetic members within a case and then exposing "them for withdrawal from the case as desired.
