Definitions

  • the present invention relates to an illuminating system for industrial appliances, and more particularly for machine tools, machines and apparatus of other kinds.
  • my invention comprises in combination a member adapted to be rigidly connected to the industrial appliance, a reflector detachably connected to said member, and a lamp arranged in the reflector.
  • the reflector is rotatable with respect to the member about an axis parallel to the axis of the reflector.
  • the member includes a part arranged for displacement along the axis of rotation of the reflector, and resilient means for urging the part into engagement with the member.
  • the member is substantially U- shaped and has two legs, each having a recess. These recesses are engaged by pin-shaped parts connected to the member rigidly connected to the reflector, one of the pin-shaped parts being arranged for longitudinal displacement in the member rigidly connected to the reflector.
  • the other of the pin-shaped parts is electrically insulated from the member rigidly connected with the reflector, and the leg having the other recess is electrically insulated from the industrial appliance.
  • a resilient clip is provided in the reflector and insulated from the body of it, an electrical connection being provided between the v other pin-shaped member and the resilient clip,
  • a slot is provided in the displaceable pinshaped part and engaged by a screw provided in the member rigidly connected with the reflector.
  • a duct is provided in the member rigidly connected to the reflector, connecting the inside of the reflector with the atmosphere.
  • Fig. 1 is a top view of an illuminating system according to the invention.
  • Fig. 2 is a horizontal section of the system shown in Fig. 1.
  • a substantially U-shaped member I is adapted to be rigidly connected to the industrial appliance (not shown).
  • the U-shaped member I has two legs 2 and 3 and is provided with a boringl for receiving the leads 5 and 6 connecting the illuminating system with a source of electric energy (not shown).
  • Lead 6 is secured to the bulk of the U- shaped member I by means of a screw '5.
  • the leg 3 of the U-shaped member I has a part 8 separated by an electrical insulation 9 from the bulk of the U-shaped member I.
  • the other lead 5 is connected to this part 8 by means of a screw Hi arranged in the part 8 and insulated from the bulk of member I by an insulating washer II or the like.
  • the other leg 2 of member I is provided with a central member I2 which is shown in the drawing in electrical contact with the bulk of the member I. It should be understood, however, that the part I2 could be insulated from the bulk of the member I in the same manner as part 8 and connected directly to the lead 5.
  • the parts 8 and 12 are provided with recesses I3 and I4, respectively, the recess I3 being preferably spherical, whereas the recess It is preferably conical.
  • the recesses I3 and M are in alignment to each other.
  • a reflector I5 is rigidly connected to a member I6 which is provided with two pin-shaped parts I! and I8, respectively, engaging the recesses I3 and Id.
  • the pin-shaped part II is connected to the member I6 by means of an electrical insulation l3 and has a spherical head 20, engaging the recess I3.
  • An electrical connection 2! connects the pin-shaped part I! to a clip 22 to be described more in detail hereinafter.
  • the other pin-shaped part I8 is arranged for longitudinal displacement in a boring 23 of member I6, and a helical spring 24 urges the conical 3 member I6 and connects the interior of the reflector I with the atmosphere.
  • a screw 21 provided with the insulating washer 28 is arranged for holding the end of the electrical connection EI in the pin-shaped part IT.
  • the other pin-shaped part I8 is provided with a longitudinal slot 29 which is engaged by a screw 30 arranged in the member IS.
  • the screw 3% limits the outward movement of the pin-shaped part I8.
  • the reflector I5 has an oblong box-like shape and is provided at one end thereof with a resilient clip 22 which is connected to the body of the reflector by means of insulating sheets or plates 3 I.
  • a lamp 32 preferably a low voltage lamp, is arranged in the reflector I5 and contacts with one end 33 the bulk of the reflector and with the other end 34 the clip 22 which is provided with an opening 35 for accommodating the end 3d of lamp 32.
  • end 33 may be insulated, if desired, from the reflector I5 by a clip similar to clip 22 which is connected by an electrical connection traversing the duct 26 and connected to the pin I3 in a similar manner as connection 2I is connected to pin-shaped part I1.
  • part I2 must be insulated from member I as indicated above.
  • the reflector i5 is connected to the member I by pressing the part i8 back into the boring 23 and introducing the member it into the hollow of the U-shaped member I, whereupon part I8 is allowed to move outward under the pressure of spring 24 and engage the recess I l.
  • the reflector is now electrically connected to the leads 5 and 5, and the lamp may be switched on by switching means (not shown).
  • the reflector I5 may be turned about the axis of rotation defined by the pin-shaped parts ii and I3 and the recesses I3 and I4 so that the light can be directed to any direction at right angles to said axis.
  • the pin-shaped parts IT and IS constitute a plug enabling the reflector I5 to be inserted in the U-shaped member I in the same simple manner as an ordinary plug is inserted in a socket.
  • the duct 26 serves for removing hot air from the interior of the reflector to the atmosphere.
  • An illuminating system for an industrial appliance comprising in combination, a U-shaped plug socket rigidly attached to said industrial appliance and having two legs and a recess located on the inner side of each leg; a plug member located within the space between said two legs and including a rigidly mounted pin engaging one of said recesses on the inner side of one of said legs of said U-shaped member and a movably mounted pin and means for resiliently urging said movably mounted pin into engagement with the other of said recesses on the inner side of the other leg of said U-shaped member, said pins and recesses being located along an axis extending transversely to said legs of said U-shaped member, whereby said plug member may be rotated with respect to said U-shaped member about said axis; means for electrically insulating said rigidly mounted pin from the remainder of said plug member and means for electrically insulating said recess engaged by said rigidly mounted pin from the remainder of said U-shaped plug socket; a reflector rigidly connected to said plug member; a resilient clip
  • An illuminating system for an industrial appliance comprising in combination, a U-shaped plug socket rigidly attached to said industrial appliance and having two legs and a recess located on the inner side of each leg; a plug member located within the space between said two legs and including a rigidly mounted pin engaging one of said recesses on the inner side of one of said legs of said U-shaped member and a movably mounted pin engaging the other of said recesses on the inner side of the other leg of said U-shaped member, said pins and recesses being located along an axis extending transversely to said legs of said U-shaped member, whereby said plug member may be rotated with respect to said U-shaped member about said axis; a reflector rigidly connected to said plug member, said plug member having passage means extending therethrough, opening at one end into said reflector and opening at its other end onto the outer surface of said plug, thereby providing an air duct which connects the interior of the reflector with the atmosphere; a lamp mounted within said reflector; and means for conducting electric current
