ABCHIBALD THORPE CROSHER, OF TE AROHA, NEW ZEALAND.
METHOD OF CONNECTING ELECTRIC "VIBES 'lO LAMP-HOLDERS, PLUGS, AND THE LIKE.
V Specification of Letters Patent.
Patented May 6, 1913.
"Application filed January 18, 1911. Serial No. 608,375:
To all whom it may concern Be it known that I, ARCIIIBALD THORPE CRosHnR, a citizen of the Dominion of New Zealand, and residing at Te Aroha, in the Provincial District of Auckland, in the Dominion of New Zealand, have invented certain new and useful Improvements in Methods of Connecting Electric lVi-rps to Lamp- Holders, Plugs, and the Like, of which the following is a specification.
The invention relates principally to lamp holders used in connection with incandescent electric light bulbs.
Hitherto in the method generally employed the wires are led through a wooden tapering plug in two parts and the ends of the wires are gripped in screw terminals. lhis arran gement has the disadvantage that there is a direct strain or grip upon theinsulation and there is considerable inconvenience in preparing the plug for the reception of the wires, and in fixing them in position.
According to my invention, a block of insulating material has a central hole through which the wires are passed. Each wire is then independently carried upward in a recess formed for its reception in the block, and is then turned over and downward through a hole to the terminal of the lamp holder, within whiclrit is fixed by-the usual binding screw. The block is carried within a dome secured to the lamp socket by a. ring nut in the usual way. The block can be made of the same diameter as the usual porcelain terminal holder.
By my invention even when the wires are released from the terminal grips it is practically impossible to pull the wire out of the plug by a direct pull, better insulation is effected than hitherto, and the lamp holder is held with greater security.
My invention is illustrated n the drawing i wherein r-Figure 1, is'a front elevation of the lamp holder, F1 2, a similar view with the parts displayed, r .3, a plan of the in sulating clock with the doin'removed, Fig. 4, an inverted plan of the insulating block, Fig. 5, a sectional on A A, Fig. 2, Figs. 6 to 9 inclusive, illustr a modification and therein Fig. 6, is an elevation one half in central section of a lamp holder, Fig. 7, a perspective elevation of an insulating block in two parts, Fig. 8, an inverted perspective plan of the upper part of the block, Fig. 9, a perspective elevation, and
Fig. 10, an inverted plan ofthe lower part of the block.
Referring first to Figs. 1 to 5 inclusive, the insulatingblock 1 has a central hole 2 through which pass the wires 3 and 4:. .Wire 3 is carried upward in a curved recess 5 thence downwardly through a hole 6 and its end connected to terminal 7 by the usual binding screw 8. Wire 4 is carried in a similar way in the curved recess 9 thence downwardly through hole 10 and its end secured to terminal 11. A boss 12 projecting from the block fits a hole in the covering dome l2 which is secured to the lamp socket 13 by the usual ring nut 14. Both wires are covered with insulating material except where electrical connection is made with the terminals. I
Referring now to Figs. 6 to 10, inclusive,
the dome 15 and lamp socket 16 are integrally formed, the socket being screw threaded at 17 to receivethe nut which supports the shade. The insulating block is in two' terminal 26 which projects through the lower part of the block and at its upper end fits arecess 27 in the lower face of the upper block. Wire 21 is carried in a similar manner in the recess 28 downwardly through the hole 29, and its end connected by the binding screw 30 to the plunger terminal 31', which is it with the plunger terminals in correct po silion relatively to the bayonet slots 35 by which the lamp is connected,
What I do claim and desire to secure by Letters Patent of the United States is 1. In a lamp holder, an insulating block having a central hole adapted .to receive both wires of an electrical circuit and two holes,
one for each of said wires independently, and diagonal recesses 1n the periphery of the block, said recesses severally communieating with the bottom of the central hole 4 in two parts, a dome and socket receiving said block, a central hole corresponding 1n the two parts of the block, curved recesses, one for each wire, and communicating with said central hole, holes one from the top of each of said recesses passing through the upper art. of the block, plunger terminals on the ower part of the block and recesses in the face of one of the blocks to receive the binding screws of the terminals and to give access thereto substantially as herein specified and illustrated.
3. In a lamp holder, the combination of an insulating block. comprising two cooperating parts, each part having a corresponding centrally arranged hole to receive both'wires of an electrical circuit, two holes in one of said parts, one for each of said wires independcntly, and lamp terminals on the other part projecting into said holes and to which said wires are adapted to be connected.
4. In a lamp socket, the combination of an insulating block having a centrally arranged opening therethrough and strain relief passages communicating with the centrally arranged opening, one passage for each of said wires independently, and spaced lamp terminals on one face of said insulating block having wire terminals adapted to be electrically connected with the wires extending throu 11 said passages.
5. I n apendent electric appliance, the combination of an insulating body comprising two cooperating parts each having a central opening therein arranged to receive both wires of an electrical circuit, other openings in said block and extending through'both parts, passageways connecting said central opening with said other" openings, lamp terminals seated in said other openings, the circuit wires being adapted to extend into said openings at the opposite ends and be secured to the lamp terminals.
6. In a device of the class described, the combination of an insulating block comprising two separable parts having corresponding central openin therethrough to provide an opening exten ing through the block to receive both wires of an electrical circuit, an inclosing casing for the block, ineans on the casing cooperating with the block to pre vent the movement of one independent of the other and separated terminal posts within one of said parts adapted to be connected to the circuit Wires and constituting lamp contacts at the lower faceof the part in which they are mounted.
