ELECTRIC SOCKET.

-Applieat1on filed March 2?, 1923. Serial No. 627,948.

To all whom it may concern:

Be it known that I, JOHN HOHL, a citizen of the United States of America, residing at Newark, county of Essex, State of New Jersey, have invented a new and useful Electric Socket, of which the following is a s ecification.

y invention relates particularly to what are sometimes termed separable sockets and particularly to key sockets having bod and cap portions adapted to be connects and disconnected.

The main object is to provide interlocking means which permit of convenient assembly of the parts and yet which prevent accidental separation.

The special object is to provide key operated means for-unlatching the parts.

In the simple form of the invention as herein shown and described, the parts are unlocked by suitable means and automatically latched and assembled. The latching means is adapted to be retracted by a special movement of the key s indle.

Fi 1 is a longitudinal sectional view of one form of key socket embodying the imrovements of my invention the section begg taken on the plane of the line 1--1 of Fig. 2 is a longitudinal sectional view of the same construction, on the plane of the line 22 of Fig. 3. Fig. 3 is a plan view of the body or switch carrying portion of the socket.

Fig. 4 is an interior view of the cap portion of the socket. 1

Fig. 5 is a perspective view of the latch member.

The cap 6 and body 7 may beof any suitable construction, for instance, of insulating material and provided. with interfitting flanges 8. The cap is provided with terminal members 9 and 10 suitably secured in place and having circumferentially ex-' tending fingers 11 and 12.

The body is provided with brackets 13 and 14 suitably secured in place, for in- J stance, b means of screws 15 and 16. The outer en s of these brackets and the fingers 59 11 and 12 are so designed as to permit the parts to be assembled-by relatively longitudinal and rotative movements.

The switch has two spring contacts 17 and 18 and a movable contact or cam memas her 19. The contact 17 may be secured in place, conveniently, as, for instance, by being placed under the foot of the bracket 14. The contact 18 may conveniently be held in place by the yoke 20 and screw 21. The cam 19 is loosely carried by the key spindle 22, which in turn issupported by the yoke 20. The center contact 23 may also be held in place by the screw 21. The screw shell 24 may be suitably held in place, for ir stance, by being molded into the body or may be held in place by the screws 15.

The latch member 25 is carried by the end of the key spindle 22 and adapted to project into a recess 26 in the ca when the parts are in their proper assem led relation.

The key spin le is mounted in the yoke 20 so as to permit not only rotation for the purpose. of operating the contact cam 19,

ut also so as to permit the key s indle to be tilted by the arm 27 of the yo e 20 to disengage the latch 25 from the recess 26. For this purpose the other arm. of the yoke 20 is slotted at 28 to guide the key spindle in the tilting action.

It will be noted that the cam 19'is always so under pressure of the spring contact 18 so as to yieldingly hold the latch bolt 25 in the recess 26. The parts carried by the cap and by the body are so designed as to permit of assembly in either of, two posiac tions one hundred and eighty degrees (180) apart, for this purpose the cap is provided with two recesses 26.

The invention is equally applicable to other types of separable socket than those made of insulating material, for example it may be embodied in the usual brass socket. Moreover certain features of the invention may be employed in sockets in which the switch is operated by other means than a key, for example in push-through sockets. It is also to be-understood, that the latch retracting means may be inde endent of the switch operatin members, or instance a separate exterior y accessible button may be provided to control the latch bolt.

What I claim is:

1. In a separable key socket, a cap, a body having interlocking parts, engageable by relative rotation of the cap and body about 5 their common axis, a switch carried by one part including a switch operating member and a latch adapted to be operated by said operating member for preventing relative disengaging movement of said parts.

2. In a key socket, cap and body members, interlocking parts carried thereby, a key key spindle for spindle carried by one member, a key fixed on said spindle. and-a latch operated-by said key spindle for preventing the separation of said members.

3. In a socket, cap and body members, interlocking arts. carried by said members, a switch infiuding a key spindle and a latch bolt carried by and operated by said preventing the separation of said members.

4. In a socket, two separable members, a key spindle operated switch carried by one member, interlocking parts carried by said members, and a latch forpreventing separation of said members operated by a non-circuit affecting movement of said spindle.

5. In an electric socket, tWo separate members, interlocking parts carried thereby and controlled as to effectiveness by relative rotation, a latch for preventing separation of said members and a latch-controlling spindle spring-held in its normal position and swingable therefrom to release said latch.

6. In a socket, two separable members, intel-locking parts carried thereby and renant.

dered effective by relative longitudinal and rotative movement of the separable members, a latch carried by'one member and adapted to engage the other to prevent relative rotation oi said members, and key operated operating part, interlocking partscarried by said members permitting assembly by relative longitudinal and rotative movement a latch carried by one member and adapted to engage the other member to prevent relative rotation of said members, and means for connecting said latch to said operating part for operation thereby.

8. An electric socket comprising a body portion and a ca portion, members adapted to interlock sai portions by relative rotation thereof, and a bolt movable longitudinally of the body and spring pressed in a direction to prevent unlocking rotation of 60 said portions.

JUHN HOHL.
