MOUNTING AND CONNECTING APPARATUS Filed Aug. 2, 1944 lNl/EN 70/? W W H?! TSCH/ MWWWW ATTORNEY Patented June 29, 1948 MOUNTING AND .CONNECTING APPARATUS Walter'WJ'Fritsclii, 'Manhasset, N. Y., asslgnor to Dell Tilelephone Labomt oriesf'lncorporated, New York, N. "a conporation :of ZNew iYm-k Application August 2, 1944,.Seiial'NoJ54Z3173 3 'Claims. l invention. relates to mountlngand "connect'i'n'g means and particularly to frame structures and arrangements therein for distributing current supply connections in telephone systems.
An object is to'simp'lify and improve such structures and arrangements for the easy accessibility and convenience of mounting and interconnecting current supply conductors and associated units.
"Heret'ofore various types of junction boxes, terimina-l'fuse boxes Jandframes have'been used for interconnecting a plurality of incoming and outgoing conductors or cables in combinations by means of terminal mounting straps and'bus-btars.
It is a feature of the applicants invention to provide an arrangement whereby conductors incoming'from a'plurality of currentsupply sources may. be connected through resistance'or condenser impedance pads in different combinationsito'outgoing conductors. The invention may be carried out by arranging a frame structure with a plurality of bus-bars connected to'the incoming conductors and to which resistance or condenser pads maybe tapped in various groups. These pads are arranged inside the frame .structure in corresponding groups with the pads in each group connected together to individual conductors "outgoing'from the frame structure. Arrangements of "this kind may be employedrin'telephone systems select such codes by establishing "connections to these outgoing conductors arranged in this'orderly manner. So also in actual telephone installations in telephone exchanges it is of considerable advantage to have structural units according to this invention that maybe prefabricated and-permanently installed singly or in groupsin space saving formations and from which code connections may be quickly selected and permanent connections made for use as ringing signal sources or for other supervisory and identifying signals.
The invention has been illustrated in the accompanying drawings in which:
Fig. 1 shows a side view of a preferred form of the applicants invention;
Fig. 2 is a cross-section taken on line 2-2 of Fig- 1;
Fig. 3 discloses a typical circuit connection and combination of resistance pads; and
"the frame.
Fig. 4'discloses an arrangement of aplurality of said frame'structures withtheir associated connections arranged ina frame.
Referring now to the drawingsa single frame structure 'consists'of'a topplate land-a bottom plate 2 which are enlarged at the front-end as shown at 4'in Fig.2. 'At'this end the "plates are .connected'by means of'an upright cross member BJsecured in openings suchas -'l inthese enlarged portions 4 of the topandbottom plates l and -2.
The opposite-narrower-ends of the-p1ates 1 and 2 bus-bars may 'consist-of'thin bands orWires connected :at each end to terminals such as [2 at the bottom of the frame and Hi at :the top "of Between'the plates I and -2 may be mounted various combinations of groups of resistance pads such as the group 15- s'hoWn-in Fig. 2 and in layers as showninFig. '1. -These various groups maybe connected by =means=of straps or wires such "as the group F6 to individualbus-bars by extending through'openings in-thep'latesB and '9 and soldered tothe bus-bars ll] and H in various combinations. For example'asshownin Fig. 2 wherethereis providedthree-resistancepads, the "pad 'I'8is connected "by means'of a'Strap ZU' to the bus-bar 2'1.
*Similaily the other two resistance pads in this group f5 'are connected respectively to bus-bars2'2 and-2 3. The oppositeends of these 'threeresistan'ce "pads l'5 are then "connected together "by having their i outgoing straps or wires threaded through a common tubular terminal punching T24 'on'the plate 6 to winch-in"turn-a common shielded "conductor "25 is soldered. The shielding 26 of each conductor 25 may be grounded through a conductor 21 to the companion terminal punching such as 28 for punching 24. All of the punchings 28 may be connected together with a strap to ground. In other words, each group of resistance pads are connected to various combinations of bus-bars at one end and to a common conductor at the other end through a terminal with the associated shielding grounded. Fi 3 discloses the circuit connections for such a combination of three resistance pads. It should be understood that the number of resistance pads in the different groups may be varied depending on what combinations are desired. The terminals for the bus-bars may be connected directly to various individual sources of alternating current as shown in Fig. 3 where one source 29 is connected through one bus-bar T, the resistance pad 30, source 3| through another bus-bar to pad 32 and source 33 through a closed bus-bar to pad 34. These pads are connected at their opposite ends to the common conductor 25.
In telephone systems it may be desirable to mount a number of these mounting units with their associated connections in groups in a common frame, for example, as shown in Fig. 1 different units may be connected on top of each other by straps such as 36 between the unit 38 and the unit above partly shown and indicated with the numeral 39, while straps such as 40 may be connected below the bus-bars of unit 38 and the partially disclosed unit identified by the numeral 4|. Theseunits may be arranged .in horizontal and vertical rows and connected to cross plates such as 43, 44 and 45 and others by screws such as 46 and 41 as shown, for example, connecting cross plate 43 with the bottom member 2 shown in Fig. 2. These plates 43, 44 and 45 and. others may be connected in any suitable manner to the frame 50. It is also evident that the sources of current may be connected to the bus-bars by cables (not shown) but strapped to frame 50 as desired. Ifhe outgoing conductors 25, etc, may be similarly arranged. A common arrangement would be to have all the bus-bars on all the units connected together to corresponding current sources through a common cable.
By this arrangement of units it is evident that various combinations of alternating current sources may be strapped through impedance pads arranged in groups to individual conductors for the supplying of combinations of different frequencies to produce corresponding signal codes as employed for various purposes in telephone systems. While the impedance pads disclosed are resistances, it will be understood that they may be capacitances or combinations of resistance and capacitance.
