To all whom z't'may concern:

-' Be it known that I, ELDA G. SMrrrr, a citizen of the United States, and aresident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Electrical Connection,

of which the ,following'risa specification.

junction with a terminal box, and'it consists in the novel features of construction here- In describing this invention, reference is had to the accompanying drawings in wh ch like characters designate corresponding parts in all the views.

Figure 1 is an elevatiomof the terminal {box and its electric connection or-plug inserted therein. Fig. 2 is-alongitudinalvertical sectional view of parts seen in Fig. 1, the terminal connection orplug being shown as moved partly out of the box. Fig. 3 is a front elevation of this electric connection, partly in section. Fig, 4 a vertical sectional view taken centrally on Fig. 3. Fig.

' 5 is a sectional view on line A-A, Fig. 3.

Figs. 6 and .7 are, respectively, an elevation I and a sectional view ofthe block of insulaother block of insulatioma terminalmounted on one of the blocks and having a stem extending in the hollow nipple for connection with awire, and a'housing mounted on said wall in position to inclose the wire connected to the-stem and one of the blocks 0 insulation. 4

1. is'the support V the form of a-b'ox open at 2 at one end and'at 3 at one side, the

' boxincluding a wallfl which is here shown as disposed opposite-to the open side 3, the wall 4: being formed with a plurality of openings or perforations as 5 therethrough.

6 and 7 are blocks of insulation mounted on opposite sides of the walla inside and outside of the box, one of these blocks being view of one formed with hdllow nipples 8 for entering the perforations 5, and the other of the blocks preferably being formed with re-j cesses for receiving said'nipples. As here shown, the block is formed with the nipples 8 and the block 6 with the recesses 9,

the block 7 having openings or passages 10 therethrou'gh which extend through the nip pics 8.

and 12 are stems connected to the terminals 11 and depending into passages 10 for connection" with electric-wires, not shown. The block 6, located inside of the box, is here 11 are terminals mounted on the block 6 shown as formed with a plurality of grooves tivelyto the grooves 13. The block '6 is pref-I erablymade of'one piece, but may be formed of two pieces, as seen in Fig. 2, in which the I -'upper portion or strip 14 is'separate .from the main bodythereofand secured thereto in anysuitable manner.

In the form shown in Figs. 3 to- 7 inclusive, the grooves '13 terminate short of the upper face ofthe block, and in theform shown in Fig. 2, these grooves extend through the'upper and lower faces of the main body of the block 6 and are closed at their upper ends by a strip of'insulation 14. The block-6 is located in a corner of the box, is extended the full width of the boxand is heldin position byretaining -members 15 right angular in form'and secured to the sides of the box by screws 16,

corresponding arms of the retaining members engaging the'front face of the block 6/and the other arms lying in recesses 17 formedin oppositeend faces of the blocks 6, Fig. 6.

The terminals ll include bases located in I the groovesv l3 and held therein'by screws 18 extending through the block 6 into said and havii'ag the nipples 8 projecting therefrom at intervals. The stems l2'may be of any suitable construction and provided With is moved into the box 23 by means of a lever 25 having bifurcations extending on opposite sides of the box 23 and means as a bail 20 extending around the end of the support or the box 1 of this connection and having detachable engagement with books 27 provided thereon.

The means for effecting the movement of the plug forms the subject matter of my copending application Sr. N 0. 787,207, filed .Oct. 28, 1911, of which application this is a division, said application, Sr. No. 787,207

1 resulting in Patent No. 1,188,568, June 27,

1916, and the terminal box 23 forms the subject matter of my co-pending application Sr. No. 811,181, filed Jan. 9, 1914.

Vhat I claim is: 1. An electrical connection comprising a support including a wall having an open ing therethrough, a block of insulation mounted on one side of said wall and havelectrical connection movable into the socket ing a socket alined with the opening, and also having a groove opening through a face thereof, the groove being alined in a lengthwise direction with the socket and with said opening, a block of insulation mounted on the other side of the wall and. having a nipple extending through the opening and into the socket, and also having a passage extending through the nipple in line with the groove, a terminal mounted on the first-mentioned block and having its base lying in the groove, the terminal projecting beyond said" face of the block in which the groove is formed, and a stem connected to the terminal and extending lengthwise of the groove and into the nipple, substantially as and for the purpose specified.

2. The combination with a socket, of an electrical connection movable into the socket and comprising a support in the form of a box open at its top and one end, means on the closed end of the box'by which the. box

is moved into and out of'the socket, insulation mounted in the corner of the block formed by the closed end and the bottom of the box and said bottom being formed with openings therethrough, terminals supported by the insulation on the side thereof toward the open end of the box, stems connected to the terminals and extending toward the openingsin the bottom of thebox, insulation mounted on the bottom of the box, and a housing mounted on the bottom of the box and inol0sing the insulation and the wires connected to the stems, substantially as and for the purpose set forth.

3. An electrical connection comprising a support including a box open at its top and at one end and having openings in its bottom, insulation extending crosswise of the box and located in the corner formed by the closed end of the box andv the bottom there-- of, the insulation being formed'with' grooves iuits front face toivard'the open end of the box, the grooves being alined in a lengthwise direction with the openings in the bot v tom of the box, terminals having theirbases extending into the grooves, the terminals extending beyond the face of the insulation in which the grooves are formed, stems connccted to the terminals and extending lengthwise of the grooves toward the openings in the bottom of the box, and insula- 'tion mounted on the outer side of the box and I having perforations alined With the holesin the bottom of the box, substantially as and for the purpose described.

4. The combination with a socket,of an and comprising a box open atone end and having perforations in its bottom, means at the closed end of the box by Which the box is moved into and out of the socket, and

a housing mounted on the box over the perforations, insulation mounted in the box, terminals mounted on the insulation, stems connected to the terminals and extending through the bottom, and a block of insulation mounted on the bottom Within the housing, substantially as and for the purpose set forth. 1

In testimony whereof, I have hereunto signed my name' in the presence of two attesting witnesses, at Syracuse, in the county of ()nondaga, in the State of New York, this 22nd day of December, 1913. ELDA' G. SMITH,
