Definitions

  • Our invention relates to machines for applying a base to an electric incandescent lamp or similar device comprising a filament or other element whose position is desired to have a definite relation to said base or to a part thereof.
  • Our machine is particularly adapted for basing electric incandescent lamps such as are used in connection with reflectors in automobile headlights, signal lam s, and projection lamps generally.
  • Suc a base is generally provided with pins which engage slots in a socket, the latter being definitely positioned with reference to a reflector. It is desirable in many cases to have the plane of the filament occupy a definite relation with reference to the plane passing throughthe pins and through the axis of the base.

  • Fig. 13 is asectional plan view along the line l313 of Fig. 10.
  • the machine partially shown in Fig. 1 is of the general type disclosed in the Fagan, Rippl, and Malloy application above referred to, and comprises a carrier 10 which is movable by rotation and has mounted thereon a plurality of heads 11, each of which isadapted to hold an assembly consisting of a base portion 12 of a lamp and another portion carrying the remaining parts of the said lamp, including a filament 13, all sealed in a bulb 14.
  • the filament 13, which, as shown, is a concentrated coil V-shaped, is electricall connected with conductors 15 and 16, whic lead to the base 12, to which they are soldered as disclosed in the aforesaid application of Fagan, Rippl, and Malloy.
  • Each head comprises a bulb holding cup 17 which issupported by a head 18 detachably mounted on a a5 spindle 19.
  • the arrangement is such that the cup 17 floats with reference to the head 18, and the friction is adjusted so that an operator may readily move the said cup in various directions and the cup will maintain its position wherever placed.
  • the cup is provided. with a depending internally threaded flange 20 with which engages a nut 21 (Fig. 5) which bears against the bottom surface of the flan e portion 22 of the head 18.
  • the spindle 19 passes through guide brackets 23 and 24 which extend from a standard 25 forming part of the head 11.
  • the spindle 19 carries a tension arm 26 which bears against a spring 27, and the holder 17 may be lowered by the operator by pressing down on this tension arm.
  • a cam 28 located at the loading and unloading positions engages a roller 29 carricd by the tension arm 26 so as to lower the 3 cup 17 through the spindle 19.
  • an operator At the loading positions an operator first assembles a lamp bulb and base lined with cement in proper relation for uniting, after which the bulb is placed in the cup 17 and held by the operator until the roller 29 rides off the cam 28, whereupon the spindle 19 is raised by the spring 27 until the pins 30 and 31 of the base 12 engage the locating plate 32.
  • the said plate is provided with aligned shoulders 33 and 34, and, as the base is raised, the operator can turn the assembly so as to cause the pins 30 and 31 to register with these shoulders 33 and 34, respectively.
  • a pair of jaws 35 and 36 which engage the same on opposite sides and, as shown in Fig. 1, are open and out of contact with the base 12 at the loading and unloading positions.
  • the opening of these jaws is caused by a stationary cam 37 (Fig. 1) as 1 each head 11 arrives at the loading and un loading positions.
  • the cam 37 is so located that when the carrier 10 moves toward the loading position, a roller 38, one of which is carried by each head 11, engages the cam 37.
  • Each roller 38 is carried by one arm 39 of a crank 39', which is rotatably mounted on a pin 40 extending from the platform 41 forming part of the standard 25.
  • a pair of links 42 and 43 carried by the crank are attached to the base holding jaws 35 and 36, respectively, so that as the roller 38 engages the cam 37 the arm 39 is caused to move outward, thereby forcing the jaws 35 and 36 open through the links 42 and 43.
  • the advance of the carrier 10 causes the head 11 to reach the observation and adjusting position B, with which our invention has more particularly to do.
  • the roller 38 rides oil the cam 37 and the jaws 35 and 36 are caused to close about and firmly grip the base 12.
  • the closing of the jaws is accomplished by means of a spring 44, which is attached at one end to the arm 45 of the crank 39', and at its opposite end to a pi'n46 of the next head 11.
  • a spring 44 which is attached at one end to the arm 45 of the crank 39', and at its opposite end to a pi'n46 of the next head 11.
  • the closing of the jaws is accomplished during the lowering of the assembly by means of the horizontally dis osed springs 53 and 54 which are connecte between the fingers 55 and 56 extending from the upper ends of the said jaws.
  • electrical energy is supplied to the jaws 47 from a source (not shown) through the conduit 57.
  • Current then passes from the jaws 47 down through the top conductor 15 to the filament 13, and out through the side conductor 16 to the jaws 48 which are grounded to the machine.
  • the jaws 47 are insulated from the machine by means of a fibre bushing 58 mounted on the shaft 49.
  • An optical projection means is also provided at this position which consists essentially of an arrangement of lenses and reflecting prisms which, as shown in Fig. 1, are supported in a housing 59 attached to a bracket 60 carried by the center column 61 of the machine.
  • images of its filament 13 are projected on a ground glass screen 62, the arrangement being such that two vertical projections of the filament are shown taken from directions at right angles to each other.
  • the vertical cross hair 63 represents a plane which has a definite relation to the plane of the, base pin stop shoulders 33 and 34.
  • the vertical cross hair 64 corresponds to the axis ofthe base, and when the center line of the. filament assing through the apex of the V-shaped ament image-registers with the cross hair 64, it indicates that the filament is symmetrically disposed with relation to the axis of the base.
  • the images are secured by means of lenses and reflecting prisms, the image 65 being projected through lens 66, reflecting prism 67, reflecting prism 68, and then vertically to reflecting prism 69, which throws it upon the target of the ground glass screen 62.
  • the image 71 is projected through the lens 72, reflecting prism 73, reflecting prism 74, and then vertically to reflecting prism 75, which throws it upon the the operator is able to obtain coincidence of v cators on said screen one image with the cross hair 63 and of the I apex of the other filament image with the cross hair 64.
  • the contacting jaws 47 and 48 are opened and raised out of the path of travel of the carrier.
  • the opening of the jaws occurs while they are being raised by means of the links 77 and 78, which are pivotally connected between the upper arms of the said jaws and the blocks 79 and 80, respectively said blocks being fastened on the bottom of the sight box 52.
  • the block 79 which sup ports the links 77 is insulated from the machine by means of a fibre block 81.
  • the lowering and raising of the contact jaw assembly is accomplished by means of a cam (not shown) which acts through a series of levers and rods so as to rotate the horizontal rod 82 which extends through the bearings 83 formed in the bracket 51.
  • Attached to the rod 82 is a lever 84 which is forked at its opposite end so as to receive a pin 85 carried by the holder 50.
