LIGHTING SET.

Specification of Letters Patent. Patented Aug; 29,1922.

Application filed March 30, 1921. Serial No. 457,091.

To all whom it may concern: I Be it known that I, LnoN B. MANSON, a citizen of Russia, and a resident of Brook- 1yn, county of Kings, State of New York;

have invented certain new and useful Tmprovements in Lighting Sets, of which the following is a specification.

My invention relates to lighting sets such as are used, for example, in the ornamentation of Christmas trees, or other objects adapted to be illuminated by a number of small lights strung or Wound about the same.

In the present devices of this nature on. the

' because requiring the use of'a junction box market much difliculty is experienced in enlarging the layout, or adding additional sets sists in certain arrangements and combina-\ p p a e tion of parts as will be more particularly pointed out in the claims appended to this specification.

"Referring to the drawing, Figure 1 shows the first of my lighting sets. F gure 2. represents one of any number of additional sets which are adapted to be readily connected with the first mentioned set shown in Figure 1.

The numeral 10 indicates some conventional form of electrical connector; for example, an ordinary plug adapted to be screwed into a-lamp socket. Secured within and in electrical contact with the plug 10 are a plurality of leads or conductors 11 and 12 of appropriate length terminating at their other end in a member 13 of an electrical connector or uick attachable couple of some orm. Another lead or con.- ductor 14 is bridged across both the leads 11 and 12 and the connectin members 10 and 13 and is adapted to supp y current to some form of translating device, for example, the

miniature lamps 15 shown in the drawing as being connected in series. That '1s,'the conductors 11 and 14 are in contact within the plug 10, while the conductors 12 and 14 are in contact within the connector 13. When additional lighting sets are to be used on the Christmas tree, or other object to be illuminated, one or more sets of the type illustrated by Figure 2 are adapted to be connected with the set shown in Figure 1. These sets are similar to that shown in Figure 1 in having leadsll and 12 connecting member 13*, conductor 14 and lamps 15?, but diifer from the first set in having a connecting member 16 in place of plug 10 which member 16 is adapted to be readily joined with the connector 13 by insertin the projecting prongs 17 within the conducting recesses in the member 13. An additional set,.

the duplicate of that shown in Figure 2, is adapted to be connected to the member 13 in the same manner. If desired, an insulatin' cap of appropriate form may be provi ed for the connector 13. in order to pre vent an accidental short-circuit of-the ter minals, or the end face 18 of this connector may ifdesired be countersunk for the purpose.

ong the advantages of the present insame 'vention'may be enumerated the saving in Wire which results from bridgin the conductor 14 across both the leads 11 and 12' and the connectors. 18 and 10, and doin away with the necessity of having an ad itional return conductor from the'last lamp 15 back to the plug 10. especially noteworthy feature is the easeof manipulation-required when additional lamps are to be electrically connected in circuit, doing' away with the necessity of having the more expensive ju'nctionboxes and also avoiding the requirement for tools which had been previously neces-P saryto connect such additional circuits to the 'unction boxes. resi es-in having the wiring continuous and in doingaway with the necessity for return leads from the last lamp of the last set to the junction box or other source of current,

the diflerent sets when connected in the manner outlined extending. in. prolongation. This last mentioned feature will be the'better appreciated whenit is understood that the additional sets shown by Figure 2 may all be made of standard length and yet enable the lighting sets to reachany desired. height in the tallest Christmas, tree, Mention ma alsocbe made of doing. -atigay with themec anical overload frequently/given to A. further advantage 7 as I the binding screws in the junction box when a large number of additional lighting sets are to beused.

I claim: i

1. In a Christmas tree lighting set, the combination with a quick attachable conmotor, of a pair of leads in contact therewith, a second connector in contact with said leads, and a plurality of lamps joined in se-' Ties and connected to one side of the leads said plurality of conductors and joining said connectors and adapted to supply cur rent to a translating device in circuit there-- with, said connectors being adapted to engage directly with one another.

3. A miniature lighting set comprising in combination a detachable connector and a pair of flexible insulated conductors secured thereto, a second detachable connector adapted for cooperation with said first mentioned connector, said pair of conductors terminating insaid second connector, and a plurality of lamps in series, joined by a flexible conductor and connected with each of the detachable connectors and in shunt with said pair of flexible conductors.

ln testimon whereof, I have afiixed signature to t is specification.
