lllllll 1 Inventor mzzzzmz EAifard 1948. w. H. ALFORD MULTIPLEX JACK AND PLUG Filed Dec. 29, 1945 2 Sheets-Sheet 2 Q m g Inventor JZZZZZ'QMZJZfOrrZ Patented Jan. 13, 1948 w re Myinvention relates to improvements in multi plexw jackandplug construction, andmore par ticularly to a plug provided with a plurality oil insulated contact. arms which are electrically connected to a terminal strip mounted in the end of ,theplug", said plug being adapted to be pushed into a cooperating jack providedwith aplurality. of; contacts, whereby various circuits may be oliened or closed'as desired, 's'aidplu'g and,
jack. further having means incorporated there-- infer, a counter wheel so that.preselectedidesig ated circuits maybe'openedor closed and thedistance the plugis pushed into the jack to-effectthis operation will be indicated. on the counter wheel.. An ob.ject of my invention is to provide an improved .-mu1tiplex,iack and plug equippedwithacounter operated. by the movement of the lugintothe jack, whereby a vi'sual/indication'will be. givenJto show the des'iredor preselected distance: the plug enters the'jacl; in: effecting the closing or opening of preselected. circuits connected with. the plug andtjack.
Anotherolojec't of my invention, in addition to the provision of a counter equipped plugarid jack, is theutilization o'fla ballistcp forholding the plug'in the jack at any desired: position to open or. close the presclectedxor'd'esiredcircuits.
A further object. is to provide 'thej ack with one ornmoresets of leaf contacts or switches; wherebyexterior; or additional circuits may be *opened orclosed prior to the functioning 'of, the switch. mechanismsin' theiack and plug.
Other objects will appear as the description proceeds.

Suitable insulated electric wires will conne th con a fi ser '8 w t the terminal s rip -39 carrie at th inward an o h plu I an irin net ho n irom t e c r t b controlled will be connected like is with the said terminal strip 2 9, The torward end oi the plug ,2 is threaded -to'receivea removable protector cap 2l ,-w1ich is-formed with' naperture 22 through which wires from the circuits to the terminal strip will pass; *A-sl-ight modification of'the contact fingers is'showirin Figure 4,"and in detail iii'EFig- 'ure 7, and includes an internally threaded meta l ferrule 23- 'whicn'is "pressed into andnsul'ating ferrule 24; which"inturnis'pressed' into theplugfl. "If desired; one "of more leaf" switches*'25 may be secured "tothe opposite sides "of the 'jacki,

The plug 2 is notched on its upper surface to form the track 21, which cooperates with and engages the cog wheel 9, so that movement of the plug into the jack causes the rotation of the counter mechanism to indicate the relative position of the plug to the jack and accordingly just what predetermined selected circuits are being opened or closed. A plurality of transverse looking grooves 28 are formed in the lower surface of the plug 2 and are positioned at spaced intervals between the laterally extending contact arms l6, and cooperate with the spring pressed plug locking ball 4 to hold the plug in the jack at the de sired position.
From the foregoing description, it will be apparent that the plug 2 will be pushed into the jack a predetermined amount to cause the opening or closing of the desired circuits, and in pushing the plug in the jack, the counter will automatically indicate the postion of the plug with respect to the jack, and accordingly, what circuits are being effected. Moreover, it will be understood that the plug will be rotated clockwise or counter clockwise to open or close the circuits by bringing the contact arms l6 into engagement with the contacts 1 supported in the grooves in the jack I.
It will be understood that I do not intend to limit myself to the exact construction illustrated in the drawings and described in the specification, as many minor changes in details of construction may be resorted to without departure from the spirit of the invention.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

A combined multiplex jack and plug comprising an elongated jack housing formed with a longitudinally extending cylindrical bore and diametrically opposed elongated arcuate slots at the opposite sides of said cylindrical bore merging therewith, longitudinally spaced contacts supported along the opposite ends of said slots, connections leading from said contacts exteriorly of said jack housing, said jack housing being formed with a radially extending slot disposed between said cylindrical bore and the outer surface of said jack housing, a cog wheel mounted transversely of said radial slot extending into said cylindrical bore, a counter supported upon said jack housing overlying said cog Wheel and operatively connected therewith, an elongated hollow plug having diametrically opposed rows of radially extending spaced longitudinally disposed detachable contact arms and a longitudinally extending cog track intermediate the rows of contacts engageable with said cog wheel when said plug is inserted in said jack housing to indicate the various circuits which are opened or closed as said plug is inserted to various position Within said jack housing.
2.
