FRANK B. COOK, OE CHICAGO, ILLINOIS. IRON-FRAMED DlsTlBu'l-INGFB'OARD Fon TELEPHONE-EXQHANGES.
- Be it known that I, FRANK B. 000K, a ein;
zen of the United States of America, and a resident of Chicago, Cook county, Illinois,
have invented a certain new and useful Imrovement in Iron-Framed Distributingcards for Telephone-Exchanges, of which the following is aspecification.
In telephone systems it is the ractice to emplo at the central stationsw at are ordinari y known .as distributing boards. These distributing-boards are employed as a means for uniting .the incoming line-wires With the Wires or`conductors leading to the switchboard apparatus. Ordinarily in 'a' structure of this character the arrangement is such that the connections can be made or broken at will and also such that the connections may be interchanged.l 2O
Generally stated, it is the object of my invention to provide an improved iron-frame distributing-board which will facilitate in the connecting and disconnecting of the linewires with theV switchboard-wires. i A special object is to provide a construction and arrangement whereby the line-wire cables may be led into the back of the board either vertically or horizontally and with as much facility one way as the other.
It is also an'object to provide certain details and features of improvement tending to i increase the general efficiency of a distributing-board of this particular character.

To the foregoing and other useful ends my invention consists in Amatters hereinafter set forth and claimed.
In the accompanying drawings, Figure 1 is a perspective of my improved iron-frame distributmghoard. Fig. 2-is a side elevation of the same. Fig. 3 is a vertical section on line 3 3 in Fig..2. Fig. 4 is an enlarged lan of one of the 'terminal blocks and the adjacent portion of the su porting-arm. Y Fig. v5 is a he terminal -block shown in in Fig. 4. Fig. 'is a side elevation of the strip of insulation in which the metal'terminal stri s are mounted.
As t us illustrated, my improved iron.- frame distributin f board may com riseA a main or body portion A of any suital` e form orconstruction. Preferably, however, this frame' involves a ,number of 4rearwardly-ex- "f tendin arms or bars a. At their forward endsvt ese horizontal arms are preferably specification of Letters Patent.

provided with vertically-arranged supports a', adapted 'to serve as mounting-strips for any of the well-known or a roved forms of protective devices. As willplli) arrangement is preferably `such that the said supporting arms are arranged vertical rows, the members of each row being united Y e,observed, the
or connected at their forward ends b one of the supports or mountingfstrips a. e character and purpose of these vertical supports a are, however, wellunderstood by those skilled in the'art anddo not, therefore, need any further-description. It is the construction of the ductors. So in the resent case the linewire cables are led into t e back of the frame-like distributing-board and are there connected lwith line-terminal strips which are mounted `back or rear portion Vof the frame or distributon the rear ends of the horizontallydisposed l supportin -arms a., andwith the arrangement .shown an describedptheot'her ends of lthese terminal strips are then connected, through the medium of the protective devices mounted. on the supports a', with the apparatus of the switchboard. The said terminal strips are, however, referably mounted on terminal blocks B, eacliblock beingremovablysecured to the rear end of one of the arms a. With this construction, the line-terminal strips Z) are all mounted on the faces of terminal blocks whichare arranged in rows both vertically and horizontally. In other words, each terminalblock is provided with a vertical strip of insulation b', adapted to. sup ort the said metallic terminal strips-Z), and when arranged as shown in the drawings 'both horizontal and vertical rowsare, therefore, made up of vertically-disp osed line-terminal strips. The body portion of each terminal block is preferably provided at each side with a number of small openings b2, arranged conveniently with respect to the opposite ends of the said line-terminal strips. Each block is also preferably provided\with a shank b3, adapted to lie in the channel of the arm a., to which it is attached. In additionto vthesefeatures a supporting-ring b4 is associated .with each termmal block and'is inserted through the said shank and su portingfframe, in such manner as'to assist in oldingthertwo together. Thus each verticall -dis osed terminal block consists, preferab y, o a body portion having a rearwardly-extending ridge b5, upon which latter can be mounted the strip of insulation b. Furthermore, the body portion of each terminal biock is preferably provided at each side with a double row of conductor-openings, the openings of one row alternating with the openings o the adjacent row, so as to secure compactness and a close arrangement of the said terminal strips. The framework or body of the distributing-board is also preferably constructed vwith a number of supporting-rings C, ywhich are adapted to support the conductors, serving as the means of electrical connection between the line-terminal strips at the rear of the board and the switchboard terminals or protective devices at the front of the' board.
Now with the foregoing arrangementthat is to say, with the provision of the terminal blocks, which are arranged in rows both vertically and horizontally at the back of the board-the connecting and disconnect- -ing of the line-wires at the back of the board is greatly facilitated. Furthermore, with this arrangement of the line-terminal strips in grou s at the back of the board the linewire ca les can be led in either vertically or horizontally, according to the conditions or requirements of any particular case. In other words, conditions are such that it is sometimes desirable and erha s most convenient to lead the line-wire ca les horizontally into the backof the board. Again, and
' on the other hand, it is often desirable and the blocks is of such character as to most convenient to lead the line-wire cables vertically into the back of the board; but in either case the distribution` of the line-wires land the attachment of the same to the linewire-terminal strips is with my im roved construction accomplished with equa,facil ity. Thus it will be seen that the blocks B, supporting the line-terminal strips b, are arranged in rows both vertically and horizontally and with ample space between. In other words, the separated arrangement pf eat y facilitate the work of establishing an disestablishing connections or of shifting or changmg connections, and in addition it will be seen that both ends of the line-terminal strips b are located at the outer side of the blocks, thus making it easy to solder on the different wires.
The specific construction of the .terminal blocks, involving, as will be observed, the arrangement of the line-terminal strips in two rows with the members of one row alternating with the members of the other row, as shown moreclearlyinFig. 7, and the ari angelment of the' openings in the terminal blocks in rows, the members of one row alternating with those of the' adjacent row is, I find of advantage, as it insures greater compactness in the arran ement of the wires and different parts and a so tends to facilitate the estab.- lslung and disestablishiug of the connections.
In making the connections the line-wires are led from the cablesthrough the rings b4 and are then distributed through the openings b2. are then soldered to their proper line-terminal strips, and, as previously explained, the connections with the switchboard are then made through the medium of wires having their rear ends soldered to the other ends of the line-terminal strips at the rear of the board and having their forward ends soldered or otherwise suitably connected with the protective devices at the front of the board. With my improved arrangement these connections can be made readily and with great n facility and can also be broken or interchanged with facility and convenience. The advantages of my improved construction wil l, however, be readily apparent to those skilled in the art. A further explanation is therefore unnecessary.
What I claim as my invention is- After this the ends of the line-wires '1.
