Application filed December 28, 1923. Serial I'm-688,128.
To all whom it may concern:
Be it known that I, HUGO GnnNsBAcK, a citizen of the United States of America, and a resident of New York city, county and State of New York, have invented cer tain new and useful Improvements in Cord Terminals, of which the following is a specification.
The objects of this invention are to en'- able the quick connection and disconnection of a number of difi'erent cord circuits with respect to the binding posts or terminals of radio or other electrical apparatus and to effect this with a simple, practical and inexpensive construction.
In the accompanying drawing formlng part of this specification there are il1ustrated several embodiments of the invention, but it is to be understood that the structure may be further varied without departure from the broad spirit and scope of the invention as will be clear from the following specification and claims.
Figure 1 is a view showing a form of the invention as applied to a radio receiving set for enabling the connection of a plurality of head sets in place of the single head set for which such receivers are usually equipped.
Fi re 2 is a broken part sectional view showing the manner in which the device can be applied to different types of binding posts and illustrating the use of single cord conductors for providing quick attachable connection between difierent pieces of electrical apparatus.
Figures 3 and 4 are plan views of the terminal as constructed with two different forms of screw enga ing lugs.
Figure 5 is a bro en view of one of the cord connectors.
Figure 6 is a sectional view of a modified form of the terminal constructed by punching the samel from a single piece of sheet metal.
The base of the terminal attachment is shown as a substantially fiat plate 7 of sheet metal elongated as indicated in Figures 3 and 4 and having a perforated screw receiving lug 8 projecting from one side of the.
neath the head of a binding screw or the like. The bar lug 9 is preferably made small enough and of suflicient length to be entered 1n the tip receiving holes ordinarily provided in a binding post.
Qn the base plate are arranged a series of spring cord tip sockets 10, the same being shown disposed in a row extending lengthwise of the plate. These sockets are shown 1n F1gures 2, 3 and 4 as formed separately and secured on the plate by riveting at 11, but they may be attached in any other way and in fact, may be struck up as integral eyelet portions of the plate as shown at 12 in Figure 6. The deslred spring ripping quality may be provided by mal ing the sockets of spring metal and slotting them 21% one or a number of cuts, as indicated a The invention is particularly useful where it is desired to connect a number of head sets with a radio receiver which is equipped with binding posts for onlv a sin le head set. This condition is illustrated in Figure 1 wherein two of the" terminals are used, secured by means of their attachment lugs 8 to the two telephone binding posts 14, 15 \of a radio receiving set. The device is equally applicable to binding posts of either the true post type such as illustrated at 16, in Figure 2 or to the simple clamp screw type such as indicated at 17 in the same figure. It will be evident from this view that the terminal may be appliedto the post binder by engaging the attachment lug 8 beneath the head of the binder screw 18 instead of inserting the bar lug or pin 9 into the binding post passage 19. The bar lug therefore is not always essential and may be omitted.
The inventiomis widely useful for connecting various forms of radio and other electrical apparatus for experimental or other use. The screw engaging lugs provide a means by which the devices can be quickly secured to the binding posts or terminal screws of condensers, transformers, inductances and the like and such parts may then be quickly connected together in various relations by means of suitable conductors.
Figures 2 and 5 indicate conductors rovided for the purpose and comprising s ort flexible sin 1e conductor cords 20 equi ped at both ends with cord terminals 21 a a ting them to be plugged into any of t e spring sockets in all the various terminals used. Thus with a number of these cords and with a number of the quickly attachable terminals it becomes ossible to readily connect a number of di erent electrical devices in practically any desired relation and to change these connections immediately, as is desirable when carrying on experiments'and the like.
What I claim is: l
1. A unitary terminal for the tips of telehone cords comprising a small metallic base plate having an integrally projecting lug at one edge for mechanical sugporte engagement w1tl1 the screw of a mdmg post, whereby said terminal is quickly attachable to or detachable from a binding post of radio apparatus and a plurality 0 spring telephone cord tip receiving sockets fixed in closely spaced relation on said base plate and forming permanent mechanical and electrical extensions of the same.
2. A unitary cord tip terminal comprising a small metallic base plate having an attaching lug portion for engagement by a binding post and a plurality of integral spring cord tip sockets on said base plate and adapted to be connected in circuit with the binding post when the base platev is applied to and supported on the post.
3. A cord tip terminal comprising a metallic base plate having an eyelet lug projecting from one edge for engagement about a binding screw and a bar lug projecting from the opposite edge for enga ement in the socket of a binding post an a plurality of spring cord tip sockets on said ase plate.
4. A unitary cord tip terminal comprising a metallic base plate perforated for engagement by a bindmg screw and whereby said terminal will be wholly supported by and electrically connected in circuit with said binding screw and a row of closely spaced integral spring cord tip terminal sockets on said base plate for receiving and connecting a plurality of cord tips in circuit with the terminal screw.
5. A unitary terminal for a telephone cord tip comprising in its entirety a small flat sheet metal plate provided with an integral telephone cord tip receiving socket having cooperating spring Jaws for gripping engagement with a cor tip and provided with an integral projecting lug at one edge havin a recess therein to receive the shank of a binding screw and whereb said plate can be quickly attached to a bin ing screw of radio apparatus and thereby form a terminal by which a telephone cord may be uickly and firmly secured in readily detacha le mechanically supported and electrically connected relation to such binding screw.
.In witness whereof, I have hereunto set my hand this 18th day of December, 1923.
HUGO GERNSBACK.
