CONNECTER.

To all/whom, t may conce/m: i

Be it known that I, REUBEN ECKSTEIN, a citizen 4of the Unite'd States, residing in the city of New York, county of Bronx, and State of New York,have invented certain new and useful Improvements in Connecters, of which the following is a true, clear, and concise description.

My invention relates to connecters, adapted for use in connecting lamps, fans, motors, heaters and other electrical devices of different kinds in order to facilitate energizing the same by means dielectric currents. More particularly stated, I seek to provide an electrical connecter of unusually simple construction, madev up of a relatively vsmall number of parts and constructed of stock material, the various parts being each of such form as to enable it to be made in quantity, the parts being easily assembled, reliable in action, and easily standardized.

My invention further contemplates a connecter so constructed and arranged that it may be quickly and accurately brought into or put out of use by a person of ordinary intelligence and having no special lmowledge of electricity, and can while in active use rest upon .a table or the like, or be suspended, which is lsafe in any position,

and which presents a general appearance rather pleasing to the eye.

Reference is made to the accompanying drawing forming a part of -this specification, and in which like reference characters indicate like parts throughout all of the Iigures.

Figure 1 is a view of my improved connecter, showing the'same as partly in elevation and partly broken away;

Figure 2 is a section on the line 2,-2 of Figure 1, looking in the direction indicated by the arrows, and showing the' plug as u disconnected Jfrom the connecter;

Figure 3 is a section on the line 3-3 of Figure 1, looking in the direction indicated by the arrows;

Figure 4 shows the contact plates alone, and 1s partly in elevation and partly broken away;

Figure 5 is a side view of the parts shown in Figure 4v;

.Application 1ec1 April 14, 1921. Serial N'o. 461,266.

Figure 6 is a' section on the line 6-6 of Figure 4, looking in the direction indicated by the arrows;

Figure 7 isa front elevation of the connecter, showing it with three plugs in position, for supplying current to as many lamps or the like.

At 9 is a face plate of insulating material, and made rather thick and massive. It is provided with eight holes 10, 11, arranged in pairs as shown, each pair consisting of one hole 11 and one hole 10. Two stamping 12, 13, of sheet metal, preferably brass, copper or German silver, are secured together by brazing, solderin welding,

5, eachf' tongue 16 is spaced a very short distance from the mating tongue 17 immediately adjacent. Thus the tongues 16, 17, carried by the front contact plate are arranged in pairs, each pair consisting of a tongue 16 and a ytongue 17.

The ace plate 9 cess 12, as shown moreV particularly in'Flgis provided with a rel ure 2, and the Contact plate lits neatly into this recess, in such manner that eachv of the holes 11 is occupied by a pair of tongues 16, 17 the tit being rather loose in order to allow the tongues a little freedgm of move- .ment

Two other sheet metal stampings 14, 15, are provided with tongues 18, 19 arranged in pairs as above described, the stampings 14, 15 being secured together in the same man- 'ner as the stampings 12, 13 and being as a whole designated as the back contact plate. The contact plate is mounted upon a plate 20 of insulating material, such as hard rubber, porcelain, compositions used as substitutes for hard rubber. I designate the plate 20 as middle or any of the well known.

plate. The face plate 9 an'd the middle plate are preferably made of the same material, -but this is not essential. The middle plate is provided with a recess 20a, into which the back contact plate is sunken, as indicated more particularly in Figure 2, the parts being soarranged that when the back contact plate is in position the tongues 18,

' 19 extend through the holes 10, in the same 23 and with revoluble nuts 24.` These heads and nuts are sunken by means of holes 25, 26. A lamp cord 27, of the Akind known as a. double cord, comprises a pair of single cords 28, 29, each being secured by a solder joint to one or the other of the contact plates. The front plate 9 is provided with a channel 9, merging into 'the recess 12,

and the middle plate 20 is similarly provided With a channel 20", merging into the recess 20, the channels 9a and 20" being used as passages for holding the cords 2 9, 28

Associated with the connecter are plugs 31, of which three are here shown. The connecter Vas here shown and described is adapted for use with four such plugs, but

obviously the number may be varied. Each plug 31 is provided with a lamp cord 32 wherewithit is supplied with electric current, andfrom which it may be suspended. Each plug 31 is provided with a pair ot contact blades 33,`34,Vso arranged that by using the plug as a handle the blades may be thrust into a pair of the holes 10, 11, so that one of the blades engages a pair of tongues 16, 17, the other of the two blades engaging,lr the mating pair of tongues 18, 19.

Each lamp cord 32 leads from its plug 31 to alamp, a fan, a heater or the like, to be energized. A

The connecter as a whole is adapted to be suspended or rested upon a table or the like, and is so `finished and proportioned as to present to the eye an attractive appearance.

The operation of my device may be readily understood in the light of the foregoing description. IThe various parts being assembled and arranged as illustrated and described; the connecter is either suspended by means of the double cord connected with it or is rested upon a table or the like, and

A 'is then ready for use. fIhen, Whenever the operator desires to supply current to a lamp or the like, he merely inserts one or more `charged are exposed.

This connector is of a fern well adapted for conserving both time andmaterial in its manufacture. It is well adapted for quan'- It is ool proof, in

tity production. Its various parts can easily be made `from general stock material, and

the different individual parts may readily be standardized.

I do not limit myself to the particular mechanism shown, as variations may be made therein without departing from the 'spirit of my. invention, the scope of which is commensurate with my claims.

I claim- 1. The combination of a plate of insulating material provided with a number of holes extendingthrough it, a contact plate mounted upon said plateV of insulating material and provided with tongues of conducting material extending through some of said holes and arranged in pairs, a second plate of insulating material connected with said irst--mentioned plate of insulating material and provided with holes extending therethrough and a second contact plate, said second contact plate being provided with tongues of conducting material arranged in pairs and extending through the holes in said second plate of insulating material and also through some of the holes in said first-mentioned plate'of insulating material.

2. In a connecter the combination of a plate of insulating material provided with a number of holes extending through it, a contact plate carried by' said plate of insulating material and provided with tongues arranged in pairs and extending through some of said holes, a second plate of insulating material provided with ho'les registering with some of said first-mentioned holes,

a contact plat'e carried by said second plate of insulating material and provided with tongues arranged in pairs and extending through said holes in said second plate and through the holes of the first-mentioned plate in registry therewith, athird plate of insulating material engaging said secondmentione'd contact plate, and bolts extending through all of the plates of insulating ma# terial, for holding the same together.

3. In a connecter, the combination of a plate of insulating material provided With holes extending through it and further provided with a recess into which said holes merge, a contact plate of conducting materia] lo ated Within said recess and eprovided W' h tongues arranged in pairs and. extending through some of Vsaid holes, a second plate of insulating material mounted upon said lirst-mentioned plate of insulating material and provided with holes registering with somev of said holes thereof, and
