UNlTED STATES WILLIAM H. FRASSE, Of NEWARK, NEW JERSEY.
RESISTANCE COUPLIN G.
Application filed December 4, 1924. Serial No. 753,912.
My invention relates particularly to resistance-co :pled circuits and, as herein embodied, is designed to produce, as a complete and self-contained unit, a resistance coupler, suitable and specially adapted for incorpora tion in radio amplifier or other circuits, to establish the necessary electrical relation between the successive electron-dis:harge tubes thereof.
The theory of resistance A, and well-known in the art, but I find that considerable difiiciiilty is c): erienced by the average worltcr in succ ully and se tactorily reducing the theory to practice and, as a result, the use of resistance coupled (liCllliS has bee greatly retarded. This particularly noticeable in the radio art, where multi-stage tube amplifiers now coupling is old commonly employed in which, more tronr convenience that choice, transformer con-- pling is used between the stagvs transformers of various makes and wound 1n any ratio desired, are available in the market in the form of unit COUplQiS.
The prevailing opinion being that resistance coupling is vastly superior to transformer coupling and that its general adoption would follow it made available in. equally convenient form for incorporati in amplifier and other circuits it is the obgect of the present invention to produce such a coupling, complete in unit torm, ready for instant use and adaptable to different cir cuits by being provided with removable elements, interchangealiile with others of ditlercut values.
The accompanying drawings will serve to illustrate a form suitable for carrying my invention into effect.
In the drawings- Fig. l is a view in perspective of a resistance coupler unit, constructed in accordance with my invention Fig. 2 is a view in side elevation thereof;
Fig. 3 is a View in diagram of the unit circuit, and
Fig. 4: is a circuit diagram of a multistage resistance-coupled amplifier.
'teferring to the drawings, 1 represents a base or block of any well known or suitable non-conducting material such as balcelite, hard rubber or the like.
The form and proportions of the base are unimportant but preferably it is castas a rectangular block, recessed on the underside to accomn'iodate nuts or other fastening means 2, 2, etc, of tour terminals incicatcd 3, l, 5 and 6, which are provided with clip-like extensions 3, l, 5 and 6, to ceivc resistance elements 7 and 8.
As shown, the resistance element 7 is clipped between the terminals 3 and land the resistance element 8 is similarly clipped between the terminals 5 and 6.
Additional extensions 9, 9, from the terminals 3 and 5, are provided with clips 10, 10, to receive a condenser 11, as shown.
Go lering the coupler unit, as above described, without reference to the amplifier circuits in which it is designed to be incorporated, the resistance elements and interposed condenser are connected in series, through the tour terminals oi the base, as shown in Fig. 3 and in this relation are adapted to be directly connected between the tubes of any two amplifier stages, as indicated, for example, in diagram in Fig. 4.
As shown in this figure, the terminals 3, and 4 are connected respectively to the plate and grid of the tubes of the two amplifier stages to be coupled. These connections having been made, the coupling is completed by connecting the terminal 5 to the positive side of the B-battery and the terminal 6, to the filament lead.
From the foregoing it will be seen that the coupling of two tube amplifier stages involves only the connecting ot' the four leads, above indicated, to the terminals of the coupler unit and as these terminals are clearly marked, no confusion, uncertainty or doubt can arise in the mind of the user as to the proper connections.
In adapting the coupler to different cir cuits or tubes, the user, aided by a suitable chart or table, ascertains the necessary values for the resistance elements and the condenser and secures them in position by pressing them into the clip-terminals of the base.
As the many important advantages of the invention will be apparent, from the toregoing description, it will be unnecessary to list and elaborate upon them.
Having thus described my invention, what I claim is:
1. A resistance coupling unit for tube amplifier circuits, comprising a suitable base providing a plurality of definitely spaced ill) reunea terminals by being removably held in the clips thereof.
3. A resistance coupling unit for tube amplifier circuits, comprising a suitable base 15 providing four terminals having clip extensions, and two resistance elements and an interposed condenser connected in series through the four terminals by being held in the clips and separately removable there 2 from.
