Definitions

  • Fig.1 is a partly broken side elevation o the apparatus illustratingthe complete circuit of travel of the loose sign flashing plates
  • Fig. 2 is an enlarged horizontal sectional view of the contact bank as'on substantially the plane of line 22, Fig. 1;
  • Fig. 3 is a further enlarged broken detail illustrating the construction and arrangements of the contacts;
  • Fig. 4 is a detailedside elevation of one of the contact combs;
  • Fig. 45a is a broken, front edge view of one of the spring contact combs;
  • Fig. 5 is a broken sectional view illustrating a modification of the head or reversing portion of the apparatus;
  • Fig. 6 is a horizontal sectional view as on line 6-6 of Fig. 1, showing particularly the plate lowering chains;
  • Fig. 7 is a perspective view of one of the blank forms from which various letters are cut;
  • Fig. 8 is a face view of two of the letter plates;
  • Fig. 8a is an edge view of one of the letter plates;
  • Fig. 9 is a broken detail showing the use of lighting and reflecting means for illustrating the movement of the sign plates as a talking sign window display;
  • Fig. 10 is a broken detail of lighting means for accomplishing the same effect in the vertically travelling portion of the apparatus;
  • Fig. 11 is a broken part sectional side elevation of another embodiment with the contact bank in the horizontal lower portion of the machine and showing feeding rollers for taking the used plates away from the chain conveyor which is associated with the contact bank.
  • Fig. 1 The apparatus disclosed in Fig. 1 is of the same general type broadly covered in my prior Patents 1,626,899 and 1,626,900 involv ing a stack of letters or sign plates 1, which are abstracted from the bottom of thestack and carried in succession up past a bank of electric contactsZ, which are connected with thel'amps or other sign elements of the flashsign board.
  • One feature of the present invention consists in mounting the entire bank of con tacts in a frame 3, which is pivotally supheld at the top as by means of clamp screw 5, so that the entire set of contacts, when re-' leased at the top may be swung outward and downward exposing all contacts and rendering them accessible for inspection and repair.
  • This This enables an operator to quickly find out if any contacts are injured or broken andto make what repairs are necessary.
  • Figs, 4 and 4a illustrate in edge and front views one of these units or so-called combs made up of a row of flat contact springs 6 clamped by insulating strips 7 8 in spaced relation on an insulating base plate 9.
  • the forward ends of these springs are free to flex as at the bottom in Fig. 3, as contacted by the metal letters or designs 10 on the letter plates 11 and the rearward endsof the springs are angled'toward the back plates 9 as at 12, so as to make good spring frictional contact with the terminal posts 13 set in the stationary back panel 14.
  • the sign plates are shown as taken from the foot of the stack by a pair of under-running chains 17 guided at the back of the stack over idlers 18 and extending from beneath the stack upwardly through a curved guideway l9,' thence upwardly in the vertical portion 20 of the guideway, rearwardly at the top in a curved to generally horizontal guideway 21, over guide rolls 22 and forwardly and down over guide rolls 23 to driving sprockets 24 at the bottom driven from reduction gearing in the box 25 by a suitable motor 26.
  • the outwardly facing reaches 0! these chains are shown provided with lugs or abutments 27 which engage behind the sign plates at the foot of the stack and carry the same upwardly and rearwardly through the guides described, from whence they are tumbled in reverse relation on top of the stack;
