CONDUlT-RECEPTACLE.

Patented July 17', 1906.

Application led October 25,1905. Serial No. 284,305.

To all whom it may concern.-

Be it known that I, FRANK T. WHEELER, a citizen of the United States, and a resident of Plainville, in the county of Hartford and State of Connecticut, (whose post-oHice address is Plainville, Connecticut,) have invented certain new and useful Improvements in Conduit-Receptacles, of which the following is a full, clear, and exact description, whereby any one skilled in the art may make and use the same.

The invention relates primarily to receptacles or perha s more properly sockets-that is, a receptac e contaming contact members arranged to connect an electric circuit through any device by insertin within the receptacle a plu -like member aving suitable contacts an conductors.

It relates more particularly to what is klnown in the art as a waterproof receptac e.

The objects ofthe invention are to rovide an insulating-receptacle having a sma l number of parts and with each of the various parts so associated and united as to produce a structure which will withstand great strains and hard usage -without liability` of disarrangement. i

A still further object is to arrange the contact parts of the receptacle in such manner that the attached conductors may be intimately and ositively united with the contact parts belore final assembly.

A still further ob'ect is to provide a receptacle ada ted for con uit use.

Referring to the dra ngs, Figures l, 2, 3, and 4 show in detailed rtical section the several parts unassembled. Fig. 5 is a central sectional view with the p ts assembled. Fig. 6 is a detail plan view of e insulating cup or receptacle.

t has been the common practice to use a Shell of insulating material, molded netherwise intimately united with a shell-like contact member forming one terminal of the circuit and a central contact member providing the terminal of opposite polarity. Ordinarily in such structures the central contact and the tubular or shell-like contact have been independent one of the other.

It is one of the purposes of the present invention to combine the outer or shell-like contact and the central contact in a single structure, to which the conductors ma be rmly and positively applied, as by so dering, rovidmg, of course, a suitable insulation etween the two contact members.

In the accompanying drawings the numeral 1 denotes a base of insulating material having an upwardly-extending tubular or- 6o tion 2 and integral lugs 3, by which the ase or receptacle as a whole may be secured in place.

On diametrically opposite sides on the base 1 are openings 4 and 5, through which 65 the conductors attached to the contact members (hereinafter described) are led out. It will be noted' that these conductors roject outwardly from the base 1 at a consi erablc distance above its point of attachment, 7o whereby insulation of said conductors from a metallic or other conducting-support is insured.

Within the insulator 1 and at some little distance above the bottom of its central bore is formed -`the ledge 6, which forms a sto and sup ort for the tubular contact mem'er 7 wit its contained central contact. One of the outletassages, as 4, is formed through the wall o this ledge, and as the parts, are 8o brought together a space 8 is left between the bottom of the bore of the receptacle 1 and the contactfshell 7. An opening 9 is provided through the bottom of the base to its g central bore, through which ,a ,suitableinsu....8 lating material ma be ilowed to fill thespaceM 8 an lnsure perfect insulation of the enter- .Qlgnglllmersand-conneetedcontactsn e contact-shell 7, as herein shown, consists of a'screw-threaded shell, though this 9o form may be varied to suit the exigcncies of any particular case, and a straight plug or screw-threaded luv may be used by varying the form of the slliell 7.

In the lower edge of the shell is secured a 95 button of insulating material 10, recessed at its center, as at l l, to receive the central contact-stud 12. As shown in cross-section, this insulating-button is substantially in the form of a half-oval and on its bottom has a recess roo 13 for purposes hereinafter defined. This insulating-button is inserted in the end of the tubular member 7, and the lower edge of the tulle is then spun over the bottom ofthe button, thereby uniting it and holding it iirml in place on the bottom of the contact-Shel The central contact-button 12 is of a suitable form to enter the opening 11 and has a head 14 and stud 15, Which give it a rm bearing in the button 10. It has a central bore 16, into which may be introduced the end of the conductor 10, preferably held therein by soldering, and as the solder is flowed into the recess 13, formed about the opening 11, said solder will not only firmly umte the conductor and contact 12, but forming a sprue in the recess 13 will prevent disengagement of the button 10 and contact 12.

The second conductor is soldered to the shell 7, and thus all soldering operations may be performed While the shell, with its contained insulatin -button 10 and central contact 12, is pulle out of the receptacle 1.

By pulling upon the conductors after they have been passed through the openings 4 and 5 the contact members Will be firmly seated upon the ledge 6 Within the receptacle, and thereupon the insulating material introduced through the openin 9 and filling the recess 8 Will securely holt? the parts and insulate them perfectly.

Obviously various forms of receptacle and' contact members might be used, and the device might be materially changed as to detail without departing Jfrom the spirit or intent of the invention.

at I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with a base of insulating material, a tubular contact member having secured in one end an insulating-button of convex form with a concave recess in its lower side and a central contact member iitting within said button and having a part projectin therethrough and into the concave recess, su )stantially as described.

2. In combination in a receptacle, a base of insulating material having a central bore,a

ledge formed on the inner wall of said bore,

conductor-openings passing through the walls of the receptacle below the ledge, and contact members supported by the ledge 1Wilth one contact member resting upon the e ge.

3. In combination in a receptacle, a base of insulating material having a central bore, a ledge formed on the inner wall of said bore, conductor-openings passing through the Walls of the receptacle below the ledge, a contact member resting upon the ledge, a coperating contact supported by the first-named contact member and means for introducing an insulatin material though the bottom of the receptac e.

4. In a receptacle, in combination with a tubular and central contact, a base of insulating material surroundingsaid parts and provided with a ledge or sto forming a seat for said parts with a recess eloW the ledge, conductor-o enings Walls of the ase of insulating material below the ledge, and insulating material filling the recess.

' 5. In combination in a receptacle, a base of insulating material provided with an internal stop, -tubular contact member located within said baseand seatdupon the stop, having secured thereto an insulatingbutton With an opening therethrough, a central ggntact member fitted Within the upper side of said opening, having a tube extendin therethrough to receive `conductor and means for uniting the condlt-or' and central contact and simultaneously locking the contact and the insulating-button.

6. In combination in a receptacle, a tubular contact member having a bottom of insulatin said ottom, a recess formed about said contact-opening on one side of the insulatingbottomto retain a mass of solder, a contact having a part adapted to project through the contact-opening into the recess and means including the solder and a conductor for firmly uniting the contact and insulatingbottom.

7. In combination in a receptacle, a base of insulating material having a central bore, a ledge or stop formed on the inner Wall of said bore, conductor-openin s passin through the Walls of the receptac e below t e ledge, a contact member resting on the ledge and forming a support for a coperating contact member and the coperating contact member.

8. In combination in a receptacle, a base of insulating material having a central bore, a ledge or stop formed on the mner Wall of said bore, conductor-,openin s passin through the walls of the receptac e below t e ledge, a contact 'member resting on the ledge and forming a support for a coperating contact member and an insulating-button surrounding said coperating contact member.
