Definitions

  • the present invention relates to lamp holders, more particularly to lamp holders for tubular lamps, such as fluorescent lamps. It is especially useful in lamp holders for tubular lamps of the 7 type having a single oval-shaped contact at each end and it is this application of my invention which I have elected specifically to illustrate and describe. It is to be understood, however, that thisis only 'by way of example and that the invention may be used wherever found applicable.
  • the object of my invention is to provide an improved lamp holder which offers a high degree of safety as hereinafterpointed out, and for a consideration of what I believe to be novel and my invention, attention is directed to the following specification and to the claims appended thereto.
  • Fig. 1 is a side elevation showing two lamp holders embodying my invention mounted in spacedrelation on a supporting plate and having a tubular lamp mounted therein, the
  • Fig. 2 is a perspective view of one of the lamp holders and an end of a lamp ready to be inserted into the holder
  • Fig. 3 is a sectional view through the lamp holder
  • Fig. 4 is a detail sectional view taken on line 4-4, Fig.3, and
  • Fig. 5 is a detail sectional view showing certain of the parts in a position different from that in Fig. 4.
  • I indicates a tubular lamp having a single oval-shaped contact 2 at each end for insertion into a lamp holder. At opposite ends, the lamp is provided with shoulders 3 for cooperation with the lamp holders as hereinafter pointed out. Lamps of this type are mounted: in their holders by inserting the contacts 2 edgewise into the lamp holders and then turning the lamp through an angle of 90 to bring the oval-shaped contacts to a position transverse to the lamp holders.
  • the lamp .holder comprises a base 5 of suitable insulating material, such asporcelain, the base being formed of walls which define a tubular passage a suitable distance.
  • the wall adjacent slot ll is countersunk to provide a ledge l2 which surrounds the slot.
  • This end of the base is provided also with inwardly extending projections 13 which terminate in spaced relation to each other to form a continuation of. slot H.
  • projections l3 form in substance an end wall for the base through which end wall the slot H extends.
  • the end wall is beveled as indicated at I 4 to provide surfaces for directing a contact 2 into the slot II.
  • On the inner sides of projections l3 are inwardly extending parts 15 which form spaced stops, one on eaph side of the slot I I.
  • a contact carrying block Fixed against mounting surface It! is a contact carrying block comprising a rectangular plate It of suitable insulating material on the outer surface of which is riveted a metal contact late I! by means of rivets I8.
  • One end of the block is attached to surface II] by a hollow rivet IS, the other end of the block projecting into passage 6.
  • Rivet Is at its inner end is threaded to receive a contact screw 20 by means of which an electrical conductor may be connected to the lamp holder.
  • Attached to contact plate H by means of 'spot welding or the like is a U-shaped contact member comprising a base 2
  • the contact arms 22 are connected with the binding post 20 through contact plate ll.
  • contact arms 22 are spaced back from slot H as shown particularly in Fig. ,4 so as to be out of line with the slot.
  • Attached to insulating member l6 by suitable rivets 23 are a pair of spring arms 24 which extend parallel to contact arms 22 and at their free ends terminate I in reversely bent parts 25 for the reception of a lamp contact 2 between them.
  • the extremities of spring arms 24 are angularly bent for engagement with stops l5.
  • Spring arms 24 are connected together at their ends adjacent insulating member 16 by a rivet 26 which holds in place also a, pair of spring arms 21 which at their free ends have contact buttons 28 which engage with parts 25.
  • the purpose of spring arms 21 is to give added spring tension to the arms 24, the inherent spring of arms plus the spring of arms 21 serving to hold the free ends of arms 24 in engagement with stops l5 and, when spread apart, to hold firmly a lamp end 2.
  • the guide or guard comprises two parallel arms 30 which define between them a groove 3
  • arms 30 are shown as being formed integral with a base plate 3i] which is attached to a flange 32 which forms in Fig. 1.
  • the lamp is moved upwardly to bring its ends between the two guides SI, the contacts 2 at the same time entering the slots II and being brought to a position between spring ends 25, as shown in Fig. 4.
  • the lamp is then turned through an angle of 90", thus locking the contacts 2 between the spring ends 25 and at the same time spreading the spring ends apart to make engagement with the contact arms 22.
  • Base or support 34 may be a part of a lamp fixture.
  • hook 31 Carried by flange 32 and mounted thereon so that it may swing to a limited extent is a hook 31 which may be used to temporarily support a lamp end when the lamp is being positioned in its holders.
  • hook 37 is shown as being provided with two inwardly facing,
  • cross bar 39 which forms a part'of the hook, is
  • Hooks 31 serve also to catch a lamp and support it should a lamp accidentally fall out of the lamp holders.
  • Fig. 1 shows two lamp holders mounted on a electrical shock.
  • a lamp is inserted in the holders usually by a person standing on a ladder. In inserting a lamp in a holder, one end of the lamp may be rested in the book 31 of one holderafter which the other end of the lamp is positioned in the hook 31 of the other holder after the manner shown in dot and dash lines What I claim as new and desire to secure by Letters Patent of the United States is:
  • a lamp holder for an elongated discharge lamp having contact means at each and comprising, in combination, a base having a guide slot therein extending to one edge of the base. a contact member carried by said base with an end adjacent the slot but out of alignment therewith, a movable member positioned in said base between an edge of the slot and said contact member and being adapted to be'engaged by the lamp contact means seated in the slot, said movable member being normally spaced from said contact member so that it is out of the electric circuit but being movable upon rotation of the lamp contact means to complete an electrical connection between the contact member and the lamp contact means, and a member having guide edges parallel with the edges of the slot but spaced therefrom to provide a guide for the lamp end for guiding the lamp contact means into the slot for engagement with the movable member upon transverse movement of the lamp, said guide edges preventing angular sideways movement of the lamp so that said movable member cannot be moved into engagement with the contact mem ber except upon rotation of the lamp.
  • abase having walls provided with a guide slot.
  • contact means carried by said base adjacent the slot, said slot beingadapted to guide a lamp contact into engagement with said contact means and hook means carried by saidbase for initially supporting a lamp spaced from said base but so that the lamp contact is in alignment with said slot for engaging said contact means upon transverse movement of the lamp into the lamp holder.
