PIERRE MAX RAOUL SALLES, OF CAUDERAN, FRANCE.
INCANDESGENT-ELECTRIC-LAMP HOLDER.
Application filed February 18, 1918.
To all whom it may concern Be it known that I, PIERRE MAX Recon SALLES, a citizen of the French Republic, residing at Cauderan, Gironde, in France, have invented certain new and useful In1- provements in In-andescent-Electric-Lamp Holders, of which the following is a specifi cation.
The subject of the present invention consists in an incandescent electric lamp holder in which the insulation of the conductors perfectly insured and the mounting of which is very quickly effected without the help of an too].
In the annexed drawing Figures 1 to 8 illustrate portions of the holder shown as sembled in Fig. 9.
Fig. 1 is the fixing ferrule.
Fig. 2 a section of the upper stopper.
Fig. 3 the plan view of this stopper from beneath.
Fig. 4 illustrates one of the terminals of the holder.
Fig. 5 is a section of the same terminal.
Fig. 6 shows the perforated piston of this terminal lowered so as to allow the end of one of the onductor wires to engage in the hole.
Fig. 7 is a section of the lower stopper.
Fig. 8 is a plan view of this stopper.
Fig. 9 illustrates in section the whole of the holder after the placing in position of the different constituent parts and the joining of the conductor wires to the terminals.
Fig. 10 is a side view and Fig. 11 is a section of a modified construction of lamp holder.
Referring to Figs. 1 to 9, the fixing ferrule a is a metal tube into which the stoppers can freely pass, the upper part of the ferrule having a. rim against which is ap plied a shoulder on the first stopper, the pins of the second stopper engaging in the notches Z Two other notches c serve for the fixing of the electric bulb.
The two stoppers are substantially of cylinder-shape and of like diameter and made of any insulating material such as wood or ebonite.
The upper stopper cl has a threaded cavity e and at the bottom of this cavity are holes I ending in oblique grooves h on the lower surface of the stopper.
Two other'cavities 9 provided in this same Specification of Letters Patent.
Patented Apr. 13, 1920.
Serial No. 217,838.
surface of the stopper serve to receive the ends of the terminals to which are connected the conductor wires which pass through the passages 71.
Each terminal is composed of a tube 5 in which are arranged the pistons lo, the heads of which abut against the rims obtained by heading at each end of the tube, these pistons being kept in this position by means of the spring Z.
.\s in some known form of connectors, the tube a is pierced, diametrically and on each surface, with a hole or the piston having also a ierforation n, at such a distance that the hole of the piston. is above that of the tube, so long as pressure is not exerted on the outer end of the piston. j.
The lower stopper 0 also possesses two shouldered cavities p in which are lodged the lower parts of the terminals, the contact pistons k passing freely through the stopper.
Finally the two pins 9 engage in the notches I), thus keeping together the various parts of the holder.
The mounting of this support is eflected by passing the conductors through the holes f. then by pressing on the perforated pistons of the terminals, in order to bring the holes n opposite the holes in and introducing the bare ends of the wires into the two holes.
The pressure of the springs then firmly maintains the Wires and secures a perfect contact.
After having placed the tops of the pistons in the cavities g of the top stopper, the wires leading to the terminals being sunk in the grooves h, the lower stopper is applied and the tube a is drawn down and. the stoppers slightly rotated to engage the pins q in the recesses b.
The device can he made as a unipolar, bipolar, and even tri polar holder or connector.
In the holder whirh has just been de scribed, the insulating part, into which the terminals are fitted, is composed of two superposed stoppers.
While remaining still constructed on the same principle this holder can have only one stolpper.
. ig. 10 illustrates this second type of holder in elevation.
Fig. 11 illustrates it in section.
This holder is then composed of two constituent parts. the fixing ferrule r and the stopper 8.
The stopper .5 is shouldered and is fitted intotlie ferrule r in which it is retained by the rims of punched holes t.
In the stopper are lodged the terminals and to the side of each of these lodgings there is a passage for the conductor.
Finally the upper part of the stopper has, as in the first type of support, a threaded part into which is screwed a nipple U, it the support is suspended direct to the conductors, or which serves to fix it to the various kinds of junctions.
This second. type oi support is of lower net cost than the former and also presents the advantage of having the stopper and fixing ferrule inseparable, also allowing a quicker mounting to be obtained.
\Vhat I claim as my invention and desire to secure by Letters Patent oi the United States is 1. In a holder for electric incal'idescent lamps the combination of an insulator block having sockets open on that face of the block which will be adjacent to a lamp carried by the holder and passages for wires to said sockets with combined wire gripping and terminal piston holding members reniovably inserted insaid sockets, said members comprising earh a sleeve, a pair of oppositely directed pistons therein and a spring operating to protrude both said pistons, one of said pistons having a transverse passage and the sleeve having lateral holes alinablc with said passage for the purpose set forth.
2. n a holder for electric incandescent lamps a combined wire gripping and terminal piston holding member comprising a sleeve having contracted open ends, a pair of oppositely directed flanged pistons therein, and a spring intermediate ofsaid pistons and adapted to press each of them outwardly, one of said pistons having a transverse passage and the sleeve having lateral holes alinable with said passage for the purpose set forth.
In Witness whereof I have signed this specification in the presence of two witnesses.
