HAMMER WITH MAGNETIC NAIL PLACER Filed May 9, 1955 INVENTOR.

LUCIEN E. DAOUS T ire States My invention relates to a new and useful improvement in a magnetic hammer in which the head of the hammer is provided with a magnetic portion so that nails, brads and so forth may be held in position to project outwardly from the side of the hammer head and thus be driven into position.

It is the object of the present invention to provide a hammer of this class which will be simple in structure, economical of manufacture, durable, compact and highly efficient in use.

Another object of the invention is the provision of a hammer of this class having an inserted magnet positioned in the head with the head and magnet so arranged and constructed so that the hammering of a nail or other object into a body will not dislocate the location of the magnet in the hammer head.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the details of the structure illustrated without departing from the invention, and, it is intended that the present disclosure shall be considered to be but the preferred embodiment.

Forming a part of this application are drawings, in which,

Fig. 1 is a side elevational view of a hammer embodying the invention;

Fig. 2 is a fragmentary sectional view taken on line 2-2 of Fig. 1 slightly enlarged;

Fig. 3 is a sectional view taken on line 3-3 of Fig. l slightly enlarged and showing the parts in exploded relation.

In the drawings I have indicated a hammer comprising a handle 7 and a head 8. Formed through the head 8 is a passage 9 projecting inwardly of which centrally thereof is a circular rib 10. I provide a pair of

permanent magnets

12 and 13, each of which has a beveled end 14. Each of these magnets is enclosed in a non-magnetic sleeve 15 having one end tapered on the outer surface as at 16. The

magnets

12 and 13 are pressed into the sleeves 16 as a press fit. The sleeves 15 are then forced inwardly of the passage 9, one sleeve being inserted in the passage 9 from one end and the other sleeve being inserted into the passage 9 from the other end. These sleeves 15 are also inserted into the passage 9 as a press fit as the sleeves 15 move inwardly of the passage 9 and the tapered end 16 of the sleeves 15 engage the rib 10. The tapered end is crimped inwardly so as to engage the beveled face 14 of the

magnet

12 and 13. As shown in Fig. 2 and in Fig. 3 this n'b is wedge-shaped in crosssection so that the tapered ends 16 of the sleeves will engage an inclined face of the rib 10 and readily fold into the position shown in Fig. 2. Consequently there is an abutment limiting the movement of the sleeves 15 inwardly of the passage and also limiting the movement of the

magnets

12 and 13 inwardly of the passage.

Due to this construction, when a nail is secured with its head on the face of the

magnet

12 or 13 and the pointed end extending outwardly therefrom, the hammer head may be used to drive the nail without any likeli hood of dislocating the magnet relative to the hammer head.

Experience has shown that with a hammer constructed in this manner it becomes possible for the user to drive a nail or similar article into places which are otherwise inaccessible. It has also been proven that a considerable speed-up of working operations is thus accomplished.

Yatent By encasing the magnets in the non-metallic sleeves 15, the magnets do not affect the rest of the metallic head of the hammer and the magnets themselves are not affected because of being located within this metallic head.

What I claim as new is:

l. A hammer of the class described comprising: a handle; a metallic head mounted on said handle, said head having oppositely disposed side faces, there being a passage formed through said head from one of said faces to the other, said passage having an inwardly projecting rib formed therein intermediate its ends; and a permanent magnet inserted into said passage from each end thereof, the inner movement of the magnet inwardly of said passage being limited by said rib.

2. A hammer of the class described comprising: a handle; a metallic head mounted on said handle, said head having oppositely disposed side faces, there being a passage formed through said head from one of said faces to the other, said passage having an inwardly projecting rib formed therein intermediate its ends; a permanent magnet inserted into said passage from each end thereof, the inner movement of the magnet inwardly of said passage being limited by said rib; a sleeve of non-magnetic material surrounding each of said magnets and separating the same from the metal of said head, the inner ends of said sleeves being crimped inwardly and engaging the inner end of a magnet, said inwardly crimped ends of said sleeves engaging a face of said rib.

3. A hammer of the class described comprising: a handle; a metallic head mounted on said handle, said head having oppositely disposed side face, there being a passage formed through said head from one of said faces to the other, said passage having an inwardly projecting rib formed therein intermediate its ends; a permanent magnet inserted into said passage from each end thereof, the inner movement of the magnet inwardly of said passage being limited by said rib; a sleeve of non-magnetic material surrounding each of said magnets and separating the same from the metal of said head, the inner ends of said sleeves being crimped inwardly and engaging the inner end of a magnet, said inwardly crimped ends of said sleeves engaging a face of said rib, said inner ends of said sleeves being tapered on their outer surfaces.

4. A hammer of the class described comprising: a handle; a metallic head mounted on said handle, said head having oppositely disposed side faces, there being a passage formed through said head from one of said faces to the other, said passage having an inwardly projecting rib formed therein intermediate its ends; a permanent magnet inserted into said passage from each end thereof, the inner movement of the magnet inwardly of said passage being limited by said rib; and a sleeve of non-magnetic material surrounding each of said magnets and separating the same from the metal of said head, the inner ends of said sleeves being crimped inwardly and engaging the inner end of a magnet, said inwardly crimped ends of said sleeves engaging a face of said rib, said inner ends of said sleeves being tapered on their outer surfaces; and the end surfaces of said magnets being tapered to provide an inclined surface for engagement with the crimped ends of said sleeves.
