Definitions

  • a first object of the invention is to prevent the rotation of the metallic pin after having been introduced into the respective sleeve. 7
  • the wire whereof the pin is made is deformed at a proper point of the pin so as to receive two small projections or wings, while the sleeve is provided at its ends with notches wherein the projections or wings of the pin engage when the pin is forced into the sleeve.
  • a further object of the invention is to secure a good and lasting electrical contact between the pin and the sleeve.
  • FIG. 1 is an elevational side view of a pin according to the invention.
  • Fig. 2 is a side view of the cross section along line II-II of Fig. 1.
  • Fig. 3 is a sectional View of a sleeve according to the invention.
  • Fig. 4 is a side view of Fig. 3.
  • Fig. 5 is a partial sectional view of the rack showing the assembly of the various pieces and the pin in an intermediary position before its complete introduction into the sleeve.
  • Fig. 2. shows a cross section of the wire and itswings.
  • FIG. 3 shows'the longitudinal cross section of thesleev'e which consists of a metallic tube z provided at each end Withnotches respectively '3, 4 and 5, 6 applied on a diameter of the endfaces.
  • notches are preferably located in a same axial plane of t he sleeve as-shown
  • the wings a and b engage the notches 5 and 6 and the pin is thus prevented to rotate and to slide accidentally further into the sleeve.
  • Fig. 5 shows the pin under way to be introduced into the sleeve.
  • the structure of. the rack is schematically represented by 7 and the sleeve integral with the structure by 2.
  • the structure 7 and the sleeve 2 are covered by a layer 8 of plastic material intended to protect them against electrolytical action of the bath wherein they are immersed.
  • This protective layer has convenient openings at the ends of the sleeve allowing the introduction of the pin 1 into the sleeve 2.
  • This double blocking has the following advantages: the contact between the pin and the sleeve is maintained always at the same point, no stop within the pin is necessary to limit the inwards movement of the pin, the sleeve therefore can easily be cleaned and in case of break of the pin the portion trapped within the sleeve can easily be removed by pushing it out through the opposite opening of the sleeve.
  • the length l is chosen as short as possible. Taking in account the allowable dimensional limits of the pieces involved the length I will preferably -be chosen equal to about twice the diameter of the wire.
  • the elbow should be rounded to avoid a sharp edge liable to modify the coefiioient of friction. The shape of the bend will therefore resemble nearly the shape of an S.
  • the diameter of the sleeve should be larger than that of the wire so that the bent portion AB of the pin may form with the axis of the sleeve an angle 5 so as to buttress at the instant where the pin is forced into the sleeve.
  • the wire might have a diameter of 1.8 millimeters and the sleeve an inner diameter of 1.9 millimeters.
  • slightly different dimensions may be chosen without leaving the scope of the invention.
  • the structure disclosed herein provides the shortest current path from the rack structure to the pin when the pin is in its final position within the sleeve.
  • the current could possibly resistance of the sleeve the current will flow from the end of the pin, through the sleeve and to the rack structure. This is true when the sleeve is, for example, stainbe coated by any proper conductive and protective layer,
  • pins are fixed without screws, bolts, nuts or the like, these pins being blocked and prevented to rotate or to slide.
  • the electrical contact between the pins and the sleeves is practically constant over a very long period of utilization.
  • the pins and sleeves may be manufactured from conventional tubes and wires. The cleaning of the sleeves is easy to perform as no interior projections exist and the replacement of broken pins can be achieved due to the simplicity of the operation 25 'by unskilled persons and on the spot without having to carry the rackto the repair shop.
  • an assembly for supporting an article comprising a sleeve member, a pair of notches formed at the end of said sleeve member, and a pin extending at one end thereof into said sleeve memher, said pin having a pair of diametrically opposed wings radiating therefrom and registering with said notches, the pin having a portion of the said end extending into the sleeve member bent to torman angle with the longitudinal axis of the pin, said bent portion having a length about twice the diameter of the pin, the respective ends of said bent portion engaging against respective walls ofvsaid ReferencesCited in the file of this patent UNITED STATES PATENTS La Motte May 23,1944 Schneider Sept. 15, 1953 Stroinski Aug. 12, 1958 A! it
