TRANSFORMER-TERMINAL,
Specification of Letters Patent.
Patented Apr. 9, 1912.
To all whom it may concern:
Be it known that I, EARLE G. WINsroN, a citizen of the United States, residing at Pittsfield, county of Berkshire, State of llilassachusetts, have invented certain new and useful Improvements in Transformer- Terminals, of which the following is a specification.
tom in the past to connect the several tapsj to special end-connections independent and insulated from each other, and when it 1s 1 desired to change a conductor leading to such apparatus from one tap to another, it
has been necessary to do this in a somewhat cumbersome manner. This 1s what I seek to avoid by my invention, and Faccomplish its object by the employment of a special form of compound terminal which may extend through the casin of the apparatus, and consists broadly o a plurality of subst antially parallel conductors separated from and fastened to each other by the insulating material, so as to form a unit. The ends of these conductors inside the casing are connected each to a tap on the wmding, and the ends outside the conductors are connected each to a substantially disk-shaped conductfor member, these members being arranged coaxially with the unit and insulated from each other. In addition to the terminal, .I employ a special form of conncctonarranged so that it may be quickly attached to or de tached from the several disks, so that it may lily be connected tothe desired tap of winding.
F or fiirtherunderstanding-of my invention, reference may be had to the accompanying drawing, where Figure 1 represents an external view of a transformer or other electrical apparatus pro'i'ided with my new invention; Fig. 2
represents a section of a terminal on a larger scale; Fig. 3 represents details. of the terminal; and Figs. 4 and 5 are a section and side view, respectively, of the connectors which are used.
Referring first to Fig. 1, I have shown an electrical apparatus 1 containin windings 'which are not shown, to one end of which windings are connected terminals 3, which may be of any of the well known forms, and to the other ends of which are connected my new terminals 2.
Referring now to Fig. 2, 3 is a central conducting member or rod, to the upper end of which is attached a substantially disklike conducting member t. Around the edge of this member is a groove 5. therod 3 is an insulation 6. Surrounding these are two rings 7 and 9, which are shown as substantially similar in size and positioned adjacent to the ends of rod 3. Connecting these two rings is a conductor 8,
which will be substantially parallel to rod 3. Attached to disk9 is a disk 4:, similar to disk 4, and insulated therefrom by insulating material 10.
The terminal may be built up of a number of members similar to 8, but for purposes of illustration, I have sliown a terminal composed of two such members only. Insulating member 11 surrounds member 8 and insulation 6, and surrounding 11 are two rings 12 and 13, similar to rings 7 and 9, but of a larger diameter connected together by conductor 14. Ring 13 is. attached to a disk-like conducting member 4 similar to-disk 4E and insulated from it by an insulating member 15. Insulating member 16 surrounds 14 and insulating member 11. The several insulating members may beso constructed as to fasten the several conductors together and thus build up the terminal so as to form a convenient whole or unit. I have shown diagrammatically a source of voltage such as transformer windings consistingof a primary or secondary 17, and a secondary or primary 18. Connected to 18 I have shown three taps 19, 20 and 2 1, which are connected. respectively to ringlfi, ring 7 and central rod 3 .Terminal 22, is the other end-termi nal of winding 18. It will be obvious that 1 Surrounding use in conjunction with the terminal for readily obtaining different voltages from winding 18. This connector COIlSl-SLS of a conducting member 22, to the end of which is attached a conducting loop 22-; adapted to surround members 4, d etc., and engage with grooves 5. 24 is a sleeve which fits loosely over an end of loop 23, and is adapted by its movement to tighten loop 23 in grooves 5 in a manner which will be well understood. Fastened to conductor 22 is shown a member having a screw-thread, and in engagement with this screw-thread is a nut 26, which may be turned on member 25, and thus moved toward or away from loop 23. Such operation will move sleeve 2 tighten loop 23, and hold the sleeve in a fixed position when the loop is so tightened. Conductor 22 may be insulated in a well known manner, but I have shown it insulated by members 27 which encircle it, and consist of beads of a heat-refractory substance, such as porcelain, glass, etc.
The operation of my invention will be readily understood. If it is desired to make connection with tap 19, for example, nut 26 is unscrewed, so that sleeve 24 permits loop 23 to be as loose as possible. The loop is then slipped over the various disks until it is brought in contact with disk 4: and placed in the groove surrounding the edge of said disk. Nut 26 is then screwed up so that sleeve 24: tightens the loop 23 about groove If it is desired to make connection with any other tap, a similar course of procedure may be adopted.
\Vhile I have shown members 4 as substan tially circular and disk-like in character, it is obvious that they may be made in other shapes, and a corresponding change made in the shape of loop 23, as will be well understood by those skilled in the art. t will also be obvious to those skilled in the art that while I have shown the conducting members 8, 14, etc., and members 7, 9, etc., as being made in the form which Ihave found most advantageous for the carrying out of my invention, they may be made in many wellknown manners without departing from the spirit of my invention.
While I have described a preferred embodiment of my invent-ion, I do not limit myself to this embodiinent but seek in the appended claims to cciver all embodiments which will be obvious to those skilled in the art and will not depart from the spirit of my invention.

A compound terminal composed of a central rod of conducting material, pairs of conducting rings of varying diameters sillrounding the rod adjacent its ends and insulated from the rod, conductors joining rings of like diameter insulated from each other, the lower rings uninsulated as to their cxte riors, the upper rings and the central rod each attached to a conducting disk, said disks being substantially coaxial with and surrounding the central rod, andinsulating members insulating the disks from each other and from the central rod.
3. In combination, a compound terminal composed of a plurality of conductors attached to a plurality of substantially circular coaxial conducting members insulated from each other as to their interior surfaces, and a connector having a looped end adapt ed to inclose said members and in'eans tor tightening the said loop on said members.

In witness whereof, I have hereunto set my hand this twenty-sixth day of May 1909.
