Sl'ieciiicatioii of Letters Patent.
Appicatioii filed April 8. 1915. Serial No. 18,874.
to engage in the con'iinercial screw threaded socket or the like to connect electrical conductors. and it is the primary object ot the invention to provide a plugy of'this character which may he securely connected to and 5 disconnected from thc screw threaded shell of a socket or the like by a longitudinal movement, and without the necessity of r otating the plug or any part associated therewith.
0 It is the principal object of the invention to provide a plug .it this character consisting of a unit or integral construction, that is, constructed of a single block of suitable material. a contact vieldingly carried within said block having a portion to project through an opening in and beyond the side of the block to copeiate with the screw threaded shell of a Soclret or thc like to securely but removably retain the plug therein In the drawing accompanying and forniing a lpart of this specification, Figure 1 is a perspective View, partly broken awayl of connecting plug illustrating an embodiment of my invention.
Fig. 2 is a sectional side elevation of the plug.
Fig. 3 is a. plan view.
Fig, 4 is a view in perspective of the component contacting parts of the plug, show; ing in a diagrammatic manner the relation of the contacts to the plug and the conductor connections thereto.
Fig. 5 is a perspective view of a fingerpiece removably connected to one end of the' plug.
Fig. 6 is a perspective view, partlyin section, showing a modified construction of plug; and
Fig. 7 a. sectional detail view illustrating the yielding contact in the form of a ball.
Similar characters of v y like parts throughout the different 'views of the drawing.
The embodiment of my invention shown reference designateA in the drawing comprising a block 7 of suitable insulating material, such as vulcanite yor porcelain, of a diameter to readily pass into the screw threaded shell i of a socket, such as a lamp socket (slipwn'in a general way by E5), said block having a central contacting element S at one-end in the form of a disltcr washer held to the block by a screw engaging in the block, and which contact is adapted to engage the contact 8 in lthe Socket located centrally thereof. One ofthe conductor wires' 9 is connected to said contact, said conductor passing through a longitudinal apertureor bore 25 in the block adjacent said contact, a channel or recess extendii-ig troni said aperture to the contact so that the conductor will be Within the outer contour of the block, as clearly shown in Fig. 1.
A contact in the form of a shouldered plug or plunger, although this may be in the form of a ball if desired, as shown in Fig. 7, is
movably mounted in an aperture or bore it extending transversely through the block. One end of the aperture is provided with an obstruction in the form of a washer or eyelet 12 concentric with said aperture, the opening in which obstruction is of less diameter than the diameter of the aperture and through which the reduced end of the plunger passes so that a .portion thereof may extend beyond the side of the block, the shoulder of the plunger engagingwith said obstruction 12 preventing the same roni passing out of the aperture.' The plunger is yieldingly forced through the opening in thcobstruction by a spring 13 in the aperture` one end of which engages the plunratented Feb. 27, 1917.
ger and confined within the aperture by a metallic plate 14 closing the opposite end of the electric circuit being through the washer,
the spring and plate and through conductor wire 17 connected to said n instrumentality of a screw 18. The electric circuit is not only completed through the contact 10 but this contact also serves as the lolo plate through the plug in the socket.
spacev between the same and the block, as-
shovvn at 24, With Which the bore 25 andthe recess communicate to permit of the free passage of the conductors 9 and 17, the conductors being knotted as shown in Fig. 1', and engaging in the countersunk portion of the aperture 23.
- the screw threads of the socket s In the operation of inserting the plug into a socket, the plug is pushed longitudinally therein until the'end of the plug is seated therein Withthe contact S engaging with ythe socket Contact 8', the contact 10 moving back and forth against the tension of' the spring 13 as it rides over the scre'uy threads of the socket shell. When the'plug is seated the contact is forced or moved outward by the Spring'l?) and caused to en age with dell firmly and securely holding the plug in place, as shown in Fig. 2. To remove the plug it is c only necessary to grasp the cap 20 and eX- -A`ert an outward pull when the plug may be ireadily Withdrawn from the Socket. To
' connect the conductors 9, and 17 to the con t'acts the said conductors are :tirst 'threaded Athrough the aperture in the cap and knotted,
The conductor 9 is then threaded through the aperture 25 and the conductor 1 7 posim tioned to lie in the recess 15 when the cap is se'cured to the block and the conductors connected with the contacts. Should the plug be removed by a pull on the conductors it will be -obvious that by the Yprovision of the knotvin said conductors any, strain Will come upon 'the cap through said knot and that there Will be no strain exerted upon the contacts.
In Fig. .6 l have shown a construction in Which the cap portion is integral with the block. ln this construction the aperture 23y and the space 24 with Which the bore 25 and recess 1`communicate are cored into the block when it is molded.
Instead of employing a shouldered plunger as shown in Fig. 2, the .contact 10 may be' in the forni of a ball as shown in Fig. 7, in which case the end of the aperture 11 .is tapered thereby preventing the ball from l falling out. lt will be obvious that this same construction can -be employedin con nection with the shouldered plunger. While I -have shown only a single holding contact tvvo or more may be employed with equal facility.
Lerares Variations may be resorted'to within the scope of my invention.
