Applicationflled April 24, 1915. Serial No. 23,713.

To all whom it may concern:

Be it known that 1, JOHN T. SKINNER, a

' citizen of the United States, residing atLawstruct a multiple connection service rence, in the county of Douglas and State of Kansas, have invented certain new and useful' improvements in Multiple Service Connections; and I do declare the following to be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appcrtains to make and use the same.

This invention, which is an improvement on my pending application filed September 21, 1914, Serial No. 862,783, While relating generally to means for distributing electrical energy, appertains more specifically to multiple service connection boxes.

The principal object of this invention is to provide a multiple service connection box of the character enumerated, which, though as efiiclent in every respect as that shown in my pending application, will greatly reduce the time, labor and material now associated with the construction of the same.

Another and further object is to construct the body of the box, in such a manner as to have the former serve, not only as an incasement for the terminal connection bar disposed therein, but also as an insulator there- Another and still further object is to conbox which can be readily and quickly installed whereyer desired, as well as one that will expedite the connecting or disconnecting of numerous electrical devices with a source of electrical supply.

With these and other objects in view, my inventlon consists of certain novel details of construction, combination and arrangement of parts to be more particularly hereinafter set forth and claimed. A A

plane indicated by the line 5-5 of Fig. 4;

Fig. 6 is a transverse vertical section of the complete device taken on the plane indicated by the line 6-6 of Fig. 5.

in my pending application above referred to, the insulating material containing the terminal connection bar is inclosed by a me tallic housing that is rather expensive to produce, and it is to the end that the necessity for a complete metallic housing be eliminated that I hav designed my present improvement, which in its illustrated embodiment, comprises a substantially rectangular body of porcelain, insulating material. Integrally formed with the body land extending laterally from approximately the central portion of each end of the same, are two attaching ears 2, the front surfaces of which are disposed in a plane spaced from the upper surface of said body as clearly shown in Figs. 2 and Moreover, the rear surface of ears 2 are ofiset from that of body 1.

A rectangular cavity 3, having its upper end opening through the upper side of said body, is fashioned in the latter for the reception of a metallic terminal connection bar 4. To'efiectively seal the connection bar 4: in adjusted position, a cement 5 composed of insulating material is interposed between the upper edge of said bar and the upper surface of body 1 as will be readily under; stood without further description. Extending transversely through terminal connection bar 4', in alined and suitably spaced relation, are a plurality of annular wire rewood fiber or other ceiving channels 6. In this connection it is I to be noted that the diameter of the two from the source of electricalsuptply. Each of the channels 6 has a pair 0 vertically spaced, alined and internally threaded openings 7, commumcating therewith and extendin in a plane at right angles therefrom, t e purpose of which will hereinafter Also communicating with each 01' the openings-7, is an enlarged annular recess 8, the outer end of which opens through the front side 'of body 1, as shown in Fig. 5. Moreover, each of the channels 6, in bar 4' opens into the lower end of a 'slmilar re- I insulating material struction, not only which communicate with ter has that cess 9, having its outer end opening through the lower side of body 1. By arranging the recesses 9 in the manner stated it will'at once be obvious that a supply or service lead wires may be readily pro ected into any of the channels 6 in the connection bar and conveniently connected with the latter.

To retain the various conductors in position, binding screws 10 are engaged with the respective openings 7, the heads of said screws being seated well within the openings 8, wherein they are protected against contact with the cover plate or other external objects.

As a protection against the elements, body lvhas'a cover plate 11 on the front face thereof, the configuration of which is coincident with that of the latter. Extending rearwardly from the side and upper edges of plate '11, are the integrally formed upper side flanges 12 and 13 respectively. The side flanges 12 have their free ends terminating in spaced relation to the upper surface of ears 2 while on the other hand, up per flange 13 has a length corresponding to the width of body 1, and is provided at its outer edge with a depending flange 14, the lower edge of which extends slightly below the upper surface of said body. This consecures the body against disintegration by the elements, but also permits the cover to be easily placed in position. I

To retain the cover plate properly positioned upon the body, both are formed with suitable openings 15 to receive fastening elements 16. Also that body 1 may be attached to any supporting member, ears 2 have therein openings 15', the upper ends of countersunk openings 16 for obvious purposes.

To avoid any possibility of short circuit, by reason of the binding screws having their heads contact with cover plate 11, the latportion thereof overlying the openings 8 extended outwardly as at 17, so that it will be sufficiently spaced from said screws; moreover, an additional protecting 18 is aflixed to that portion of the cover that lies in the path of said screws 10, as-will. be readily understood with out further description.

To enable cover 11 to be suspended upon a hook or other such element when not disposed upon the body 1, a vertically project- ,ing' aperturedlug 19 is integrally formed on the upper flange 13, at a point thereon, approxlmately central thereof, as clearly shown in Fig. 1.'

From the foregoing it will be obvious that have developed a multiple service connection box which is very simple in construction and one which at the same time is convenient, safe and eflicient in use.

Although in the above description I have described certain elements as best adapted to perform the functions allotted to them, nevertheless, it is to be understood that various changes as to form, substance, etc., may be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of this invention.

I claim:

1. A multiple service connection of the character described comprising an insulating body, the latter having a recess formed therein, a connecting bar seated within said recess, said bar having a plurality of transversely extending channels therethrough arranged in predetermined and spaced relation, and a screw opening communicating with each of said channels, said body having therein additional recesses communicating with each of said channels, said body having therein additional recesses communicating and alining with said screw opening and channels, binding screws engaged with said screw openings and passing through the additional recesses, a cover plate secured to the front surface of said body and overlying said recesses, that portion of said plate overlying the recesses being spaced therefrom, insulating material on the inner surface of said plate, and a flange formed on the upper edge of the latter and extending rearwardly therefrom substantially as and for the purpose set forth.

2. A multiple service connector comprising an insulating block having upright front and rear sides and horizontal top and bottom sides, said block being formed with a cavity opening through its upper side, with wire receiving apertures leading from said cavitythrough its lower side, and with screw receiving apertures leading from said cavity through its front side, a connectin bar received snugly in said cavity an spaced below the upper side of the block, a plastic filler in the upper end of the cavity, the aforesaid bar havin wire receiving apertures alining with said wire receiving apertures in the insulating block, and binding screws threaded in the aforesaid bar for securing current conducting wires in the wire receiving apertures of said bar, said screws having their heads disposed in the aforesaid screw receiving apertures.
