'Y UNITED STATES PATENT OFFICE.
JOHN F. LINDBERG, OF CHICAGO, ILLINOIS, ASSIGNOR T0 RELIANCF DIE AND STAMP- ING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
ELECTRIC SWITCH.
Application mea June i9, 1922. seriai No. 569,347.
To all whom t may concern:
Be it known that I, JOHN F. LINDBERG, citizen of the `United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Electric Switches, of which the following is a full, clear, concise, and exact description.
The invention, broadly speaking, resides in a switch through which a circuit is closed, this switch including two engaging complemental contacts and a telephone receiver or other translating device having two terminals engageable with the aforesaid con tacts, one-oi theser contacts being operable by the terminal engaging it to separate this contact from the contact complemental thereto.
In embodying my invention in a telephone receiving' station employing a plurality of telephones I provide as many such switches as there are telephones through which the telephone circuit is closed. The contacts of the switches are in series in the receiving circuit and serve to establish the circuit whether one or any number of telephones are plugged in.
diere an installation includes two such switches, for example, the two outermost ones of the four switch contacts are preferably in the nature of spring clips adapted to receive the telephone terminal plugs and the remaining switch contacts are operable by the telephone terminal plugs, being in. the form ot' spring arms that are electrically connected by being integral parts of a U- shaped spring member. Bars are adjacent and spaced apart from the sides of such spring' member distances less than the thickness of the telephone terminals whereby when the telephone terminals are received between the bars and the sides of the spring members such spring member sides are moved to separate them from their complemental contacts, the electricalfconnections between the comp'lemental contacts being replaced by the telephone instruments.
The switch of my invention is of particular service when employed in connection with radio telephony, as will be apparent to those skilled in the art.
The invention will be more fully explained by reference to the accompanying drawing in which Fig. 1 is a plan view,
r partially broken away, of a switch construction made in accordance with the preterred embodiment of the invention; Fig. 2 is a sectional view on line 2 2 of Fig. 1; FigB is a sectional view on line 3-8 of Fig. 2; Fig. 4 is a perspective view illustratlng a U-shaped spring member, parts complemental thereto, andl telephone terminal plugs engaging two of the complemental contacts, one ot' these terminals effecting the separation of these contacts, the other twol complemental cont-acts being illustrated in engagement as no telephone terminals are shownl as being connected therewith; and Fig. 5 is a diagrammatic illustration of the circuit arrangement involved.
Like parts are indicated by similar characters o1 reference throughout the different figures.
The telephone receiving circuit, such as the plate circuit of a radio outfit, has its sides 1 and 2 respectively terminating in terminals 3 and 4. U-shaped spring members 5, 6, 7 and 8 are interposed between these two terminals. The sides or arms 9, 10; 11, 12; 13, 14; 15 and 16 are switch contacts. These contacts respectively have as their complemental contacts the spring clips 17, 18, 19, 20, 21, 22, 23 and 24. The spring clips 17 and 24 are respectively connected with the circuit terminals 3 and 4. The spring clips 18 and 19 are electrically connected preferably by being formed out of the same piece of strip metal with the plate 25 that connects the same. Similarly, the plate 26 electrically connects the spring clips 20 and 21 and the plate 27 electrically connects the spring clips 22 and 23. The U- shaped spring members are interposed between adjacent clips that are not directly connected. Bars 28 are adjacent the sides of the U-shaped members and are spaced apart therefrom distances that are less than the thickness of the telephone terminals 29 and 30 so that when the telephone is inserted between either side of a U-shaped spring member and an adjacent bar 28, such side will be flexed to be separated from its comswitch of my invention, `similar parts VofV 'the precise details ofconstruction shown as changes Vmay readily be made without de- :Yparting from the spirit of my invention,
but having vthus described my invention `I claim asnew and desire'to secure'by Letters Patentthe following f `l. 'The combination `of two switches, each' `switch includingtwo engaging compleinental contacts, the contacts fof these switches -being in series, one oft the contacts of each-'switch being operableby a circuit terminal engaging it to separate this -c`ontact from thecontact "coinpleniental i thereto, the two outerinostones' yof the lilour switch contacts of the series being` formed to receive circuit terminals andthe remainingswitch'contacts forming parts of a U- shaped spring member whose sides constitute these 'rein'ainingcontacts which are operable by the terminals.
y 2. The combination of two switches, each switch including two engaging complemental contacts, the contacts of these switches being in series, one of the contacts of each switch being operable by a circuit terminal` engaging itto separate this contact from'the contact-complemental thereto, the
:two outermost ones of the four switch contacts of the series being formed to receive circuit terminals-and the remaining switch contacts-forming partsof a U-shaped spring memberwhose sides constitute these vremaining contacts; andbars adjacent and spaced.
Yapart from the sides of said spring niember distances less than the thickness of the terminals and between which and said U- Vmember sides the terminals are receivable.
