lClaiins.

This invention relates to an adjustable-magnet and refers moreparticularly to a device for holding and withdrawing various metal objects" and articles.

In factories and work shops small metal parts such as washers, bolts, nuts, etc., are often dropped by the workmen and fall into narrow holes and grooves; it is often difficult to locate and pick up these parts. Furthermore, it is sometimes necessary to remove metal washers from places behind various metal parts, which can not be reached by hand.

An object of the present invention is the provision of an adjustable magnet which is simple in construction and effective in operation, and which may be conveniently used for picking up and transporting various small metallic objects which may be attracted by the magnets.

Another object is the provision of a magnetic device for picking up various metallic articles, which is so constructed that the magnets may be conveniently adjusted, depending upon the size of the objects which are to be picked up, or the size of the recesses, grooves or holes wherein the articles are concealed.

Other objects of the present invention will become apparent in the course of the following specification.

In accomplishing the object of the present invention it was found desirable to provide a magnetic device comprising a preferably cylindrical handle portion, holding a magnet provided with downwardly extending curved prongs which may be located close to each other, or spread apart, depending upon the size of the objects to be transported. The magnet is preferably held in a clamping device which can be conveniently unscrewedfor the purpose of adjusting the operative length of the prongs.

The invention will apear more clearly from the following detailed description when taken in connection with the accompanying drawing, showing, by way of example, a preferred embodiment of the inventive idea.

In the drawing:

Figure 1 shows in side elevation an article removing device constructed in accordance with the principles of the present invention.

Figure 2 is a bottom view of the device shown in Figure 3. l

Figure 3 shows the same device from another side, with some parts broken off.

Figure 4 is a section along the line 4--4 of Figure 3, looking in the direction of the arrow.

The? magnetic device", shown in the drawing comprises ahandle I! which is substantially cylindrical in shape and which includes an inner chamber 18, containing a permanent magnet IS.

The permanent magnet I 9 extends beyond the handle I1 and is enclosed by a clamp 20', having the form of a metallic envelope provided with parallel flanges 2| and 22. The clamp' 20 also encloses the upper ends of

rods

23 and 24 which are bent at 25 and 26 respectively, and extend parallel to each other through the lower portion of their lengths.

The

elongated prongs

23 and 24 are round in cross section, and are operatively connected with the permanent magnet I9, so that one of the prongs constitutes the south pole thereof. The

prongs

23 and 24 fit into grooves or recesses provided in the permanent magnet IS.

The envelope 2!] is firmly clamped over the permanent magnet l9, and the

magnetic prongs

23 and 24, by means of

bolts

21 and 28 which extend through the flanges 2| and 22, and. which carry

nuts

29 and 30 respectively.

If bolts, nuts, washers or other small metallic parts, have dropped into a comparatively shallow groove, or if they are to be removed from inaccessible recesses of a machine the user may hold the device by its handle 6 and introduce the prongs into the groove, or recess, for the purpose of picking up these small metallic articles which will become attracted by the magnetic prongs and will adhere to them. The same device may be coveniently used on comparatively flat but poorly illuminated floor surfaces for the purpose of picking up various small objects.

The user may conveniently adjust the operative distance between the

prongs

23 and 24 extending below the clamp 20, merely b unscrewing the

bolts

21 and 28 and thereby releasing the clamp 20. Then the user turns the

prongs

23 and 24 to the desired position, whereupon the

bolts

21 and 28 are screwed on again. This makes it possible to use the magnet for removing objects of various sizes. the direction of the handle, thereby varying the length of the prongs projecting beyond the handle.

It is apparent that the illustration shown above has been given by way of illustration and not by way of limitation, and that the above described article is subject to Wide variation and modification without departing from the scope or intent of the present invention. All of such variations and modifications are to be included within the scope of the present invention.

The prongs may be adjusted in What is claimed is:

1. A magnetic device for picking up various objects, said device comprising a cylindrical handle having a hollow interior, a permanent magnet having a portion fitting firmly within the interior of said handle, a sleeve firmly enclosing another portion of said permanent magnet, and a pair of prongs having inner portions clamped between said sleeve and said permanent magnet, and outer projecting ends, said prongs operatively engaging said permanent magnet to constitute the poles thereof.

2. A magnetic device for pickin up various objects, said device comprising a cylindrical handle having a hollow interior, a permanent magnet having a portion located within the interior of said handle, a sleeve, means carried by said sleeve for removably clampin the sleeve over another portion of said permanent magnet, and a pair of prongs having inner portions clamped between said sleeve and said permanent magnet, and outer projecting ends, said prongs operatively engaging said permanent magnet to. constitute the poles thereof.

3. A magnetic device for picking up various objects, said device comprising a cylindrical handle havin a hollow interior, a permanent magnet having a portion located within the interior of said handle, a sleeve enclosing another portion of said permanent magnet, a pair of flanges upon said sleeve, screws upon said flanges for removably clamping said sleeve over said other portion of the permanent magnet, and a pair of prongs having inner portions clamped between said sleeve and said permanent magnet, and outer projecting ends, said prongs operatively engaging said permanent magnet to constitute the poles thereof.

4. A magnetic device for picking up various objects, said device comprising a handle having a hollow interior, a permanent magnet having a portionlocated within the interior of said handle, means firmly engagin another portion of said permanent magnet, and a pair of prongs having inner portions clamped between said means and said permanent magnet, outer projecting ends extending parallel to each other, and bent portions located between said inner portions and said outer ends, whereby the turning of said inner portions varies the operative distance between said outer ends.
