Abstract

The magnetic sweeper of this invention includes a laterally elongated hollow body of non-magnetic material having an open top and containing a pair of laterally spaced permanent magnets. The elongated side walls of the body have outwardly extending flanges slidably receiving a pair of covers of non-magnetic material for the magnets, and the covers have outer downturned ends facing the closed end walls of the body. An opening in each downturned end removably receives a wheel axle having an enlarged end captured between the body end wall and the adjacent downturned end of the cover, and interengaging detents on the body and each cover secures the cover removably to the body. A wheel is mounted rotatably on each axle and a handle extends from the body member for manipulating the sweeper over a surface to be swept of metallic objects.

Claims6

Dependent claims

A magnetic sweeper comprising:

a) a laterally elongated body member of non-magnetic material having front, rear, bottom and end walls defining a compartment open at the top thereof,
b) permanent magnet means in the compartment adjacent each of the opposite ends thereof for attracting magnetically susceptible objects to be swept from a surface,
c) cover means of non-magnetic material releasably secured to the body member for covering the permanent magnet means,
d) the cover means having downwardly extending end sections confronting the associated end walls of the body member, each end section having an opening therethrough for reception of an axle member,
e) an axle member extending removably through each opening in said end sections and having an enlarged end confined between the body member end wall and confronting associated end section of the cover means,
f) a wheel mounted on each axle member for moving the sweeper over a surface to be swept of metallic objects,
g) a catcher member of non-magnetic material having front, rear and bottom sides, the front and rear sides being configured to engage the front and rear outer sides of the body member with the bottom side of the catcher member overlying the bottom side of the body member, and
h) handle means operatively engaging the body member for manipulating the sweeper over a surface to be swept of metallic objects.

5 more elements

A magnetic sweeper comprising:

a) a laterally elongated body member of non-magnetic material having front, rear, bottom and end walls defining a compartment open at the top thereof,
b) a plurality of permanent magnets one adjacent each end of the compartment,
c) a plurality of cover members of non-magnetic material secured releasably to the body member for covering said permanent magnets, each cover member having a downwardly extending end section with an opening therethrough for receiving an axle member,
d) outwardly extending flanges on the upper ends of the front and rear walls of the body member, downwardly extending flanges on the outer lateral sides of the cover members having longitudinally extending guide slots for slidably receiving the flanges on the front and rear walls of the body member for mounting the cover members on the body member, and means interengaging the cover members and body member for securing the cover members releasably to the body member,
e) an axle member extending removably through each opening in said end sections and having an enlarged end confined between the body member end wall and confronting associated end section of the cover members,
f) a wheel mounted on each axle member for moving the sweeper over a surface to be swept of metallic objects,
g) a catcher member of non-magnetic material having front, rear and bottom sides, the front and rear sides being configured to engage the front and rear outer sides of the body member with the bottom side of the catcher member overlying the bottom side of the body member,
h) the front and rear walls of the catcher member being of different heights,
i) detent means on upper portions of the inner side of the taller wall,
j) notch means on the outer sides of the front and rear walls of the body member in positions to register with the detent means on the taller wall to secure the catch member releasably and reversibly to the body member, and
k) handle means operatively engaging the body member for manipulating the sweeper over a surface to be swept of metallic objects.
