Definitions

  • the usual mode of construction is to manufacture a solenoid coil as a separate structural member and insert it into a groove or channel of the ferrous magnet body.
  • Such solenoid coils have been manufactured by winding a wire on a form which is of the desired shape of the coil to be produced and subsequently potting the coil with a suitable compound such as plastic, etc. Upon removal of the winding form a solenoid coil or solenoid would result for insertion into the magnet body channel. After such insertion the channel is filled with a suitable compound whereby the solenoid is permanently fixed in the channel. Leads from the solenoid are brought out of the magnet body to be connected to a current source.
  • a still further object of the invention is to provide a magnet body which will be of compact construction and arranged and constructed for easy removal of the solenoid without the use of special tools.
  • the invention comprises a magnet body having a channel for insertion of a solenoid.
  • the solenoid is wound within a channel of what may be termed an auxiliary magnet body or permanent winding form.
  • a body is provided with a large peripheral channel in which the wire is wound to form a solenoid coil and is then inserted in the radial channel of the magnet body and secured therein by means of screws.
  • the solenoid may be readily removed for repair it necessary. Connections to the solenoid are readily arranged by means of detachable plug and socket devices.
  • FIG. 1 is a longitudinal view, primarily in section, of
  • FIG. 2 is a section showing the solenoid wound in the channel of a ferrous ring or auxiliary magnet body ready for insertion into the magnet body, and which ring serves as a coil form which becomes a permanent part of the solenoid.
  • FIG. 3 is a plan view of the assembly
  • FIG. 4 is a fragmentary view showing details of the connecting means.
  • a housing 3 which carries magnet body 2 is disclosed, and it will be understood that the magnet body is of the stationary type, being secured by any suitable means to the housing.
  • the magnet body has a solenoid mounted on a bushing 4 with intermediate needle bearing 5, which bushing is in turn carried on shaft 6, all of conventional construction for use either as a clutch or a brake.
  • the magnet body has a radial channel 14 for accommodating a channel ring 11 which may be regarded as an auxiliary magnet body or as a permanent winding form for a solenoid coil 13 shown as wound therein.
  • the form 11, which is preferably of ferrous material becomes a permanent part of the solenoid coil 13 and has affixed, as by welding, a plurality of collars 16 which are threaded at 19 to take screws 21 which pass through the back of magnet body 2 through bores 20.
  • Collars 16 fit smoothly in bores 17 provided in the back wall 18 of the magnet body.
  • plug-in contact sockets 23 and 24 are formed in an insulated block 28 which is securely attached to the wall 22 of solenoid body ring 11.
  • respective metallic prongs 26 and 27 are formed in an insulated block 28 which is securely attached to the wall 22 of solenoid body ring 11.
  • respective metallic prongs 26 and 27 are formed in an insulated block 28 which is securely attached to the wall 22 of solenoid body ring 11.
  • respective metallic prongs 26 and 27 are respective metallic prongs 26 and 27 to co-act with respective plugs 33 and 34 which connect to lines 31 and 32.
  • the arrangement is such that the insulated block 28 is substantially flush both with the back wall 18 of the magnet body and the periphery of the ring 11 when the ring 11 is inserted in the magnet body.
  • the back wall 18 and the circumferential wall of the magnet body 2 are suitably notched at 35 to accommodate the insulating plug, as shown in FIG. 4.
  • a main magnet body having a face channel and an auxiliary magnet body of magnetic material having a peripheral channel with radial flanges and a solenoid coil wound therein between said flanges, said auxiliary body being rem-ovably disposed within the channel of said main body, means comprising longitudinally extending collars secured to a face of said auxiliary body and being disposed within respective bores 35 provided in said main body, said collars having internally threaded bores, and respective screws passing into said main body and into said collars to secure said auxiliary body to said main body.
  • a ringlike main magnet body of magnetic material and an auxiliary ring-like magnet body of magnetic material having a solenoid coil therein said main magnet body having a face channel and said auxiliary magnet body being removably insertable in said channel, means for detachably securing said auxiliary magnet body to said main magnet body comprising longitudinally removable fastening elements intermediate said bodies, means for eifecting detachable electrical connection to said solenoid coil comprising an insulating block carried by said auxiliary body, said main body having a portion of its material removed for accommodating said block when said bodies are assembled, said block carrying electrical contact elements for removable connection to cable terminals.
  • a magnet body having a channel in the face thereof, an auxiliary magnet body having a channel in the periphery thereof, a solenoid coil in said latter channel, said auxiliary magnet body being disposed in the channel of said magnetbody, means for effecting detachable connections to said solenoid coil and means for detachably connecting said auxiliary magnet body to said magnet body, said last mentioned means comprising at least one internally threaded collar integrally connected to said auxiliary body, said magnet body having a bore for receiving said collar and bore for receiving a screw from exteriorly of said magnet body to threadedly engage Within said collar, whereby said auxiliary body may be readily attached or detached within said magnet body.
  • An electromagnet comprising a magnet body of magnetic material having a channel therein opening inone direction, a solenoid coil support ring of magnetic material having a channel opening in a direction normal to said first-mentioned direction and having a solenoid coil a "2 in said latter channel, said support ring being movable into and out of the channel of said main body whereby said solenoid coil is substantially surrounded by magnetic material when said ring is disposed therein, means for effecting electrical connection to said solenoid coil when said support'ring is in said magnet body and for securement of said ring to said magnet body.
