Application ma February is, 1 214. Serial No. sienna To all whom it may concern:
Be it known that I, SIDNEY of the United States, residing county of Wayne,- State of Michigan, have. invented a certain new and useful Improve: merit in Electrical Binding-Screws or Tor-- minals, and declare the followin to be a full, clear, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part. of this specification. V
My'invention relates to an electrical binding screw or terminal, shown in the accompanying drawings and more particularly pointed out in the following specification and claims.
One object of this invention is to provide a device simple and inexpensive in construction and capable of receiving and engaging the several forms of connectors or conductors in common use. A
Another object is to provide for the adjustment of the terminal stud so th'ii. it may be adapted to" receive the conductor at whatever angle or direction it may be'most con- SMITH, citizen venient to lead the same to the terminal.

In the drawings accompanying this specification: Figure 1 is a longitudinal section of the terminal with parts broken away and. in elevation. Fig. 2 1s a like sectional view showing the opposite end of the post indicated in Fig. 1, with a removable cap engaged thereto, this device being employed on'certain electrical apparatus in which it is desired to connect the elements lodged within an inclosing wall to a post with which other conductors are engaged on the outside of the wall. Fig. 3 is a cross sectional cap on line 3-3 oi Fig. 1. Fig. 4 is a side elevation of the cap.: Fig. 5 is a perspective view of a modification of the cap showing it circular in form and milled Fig. 6 is a longia modification, in which the post and cap portion are integral.

plost convenient. The cap B is threaded a portion of its length-to receive the cap nut C andthe enlarged end A of the post A,-
it being recessed at b so that when the post and cap are assembled as shown in Fig. 1, the annular cap B is free to turn upon the post A without disturbingthe adjustment of the cap .with respect to the post. It may thu be turned in either direction in order that any of the several apertures provided the conductors.
D is a lock nut on the 0st paratus to which it may be attached.

I) is a rectangular aperturein the cap through which an electrical connector having a flat or bifurcated blade may project.

F- is a conductor having projecting into the enlarged opening I) of the cap where it is engaged by the end of the cap nut C. The cap B tus when it is desired to connect elements inclosed by a wall G, with the conductors connected with the post 'on'the outside of said inolosing wall... The post A at this end in position.

difle rent diameters in the cap B through which wires or other suitable conductors 9 a flattened end In the modification shown in Fig. 6 the cap B is integral with the post A, the cap nut C and other parts being identical with like pa lt's previously described.
Having indicated" the several parts by reference letters, the construction and 0perat-ion of the device will be readily understood. It will he noted that the device is de signed to receive the ends oiiagreat variety of forms of electrical conductors, and that I they may be readily connected with the terminal stud when led thereto from any direction and under varying conditions. For example a wire may be connected with the terminal through the central aperture 0 in the cap nut C and given a right angled bend within the annular cap B, the end of the nut being adjusted so as to engage thewbent portion of the wire between the nutsfan lBtlie enlarged end of the post ;or wire. aorgot-he'r conductors of circuh r form -in' cross section and of different dian'leters may-be led into the cap at I1 6 or o", the end of the conductors being engaged by the nut-' and the enlarged end of the post A. If the conductor employed has a bifurcated end, the tines of the bifurcated portion may be forced between the end oi the nut and the outer face of the cap, the tines straddling the stem of the nut, as indicated in Fig. l :or if the end of the conductor is provided with a relativelybroad flat undivided end, it may be inserted through the rectangular aperture b of the eap,and the cap nut C adjusted so that it may be engaged between the end of the nut and the wall of the cap, which is also clearly shown in Fig. 1. If desired the large end of the post may engage the threaded portion of the cap and form an anvil against which the end of the conductors may be forced by the adjustment of the cap nut. If itis desired to adjust the apertures of the cap so that they may radiate in any required direction the cap may be rotated on the post without disturbing the adjustment of the lock not I), when the enlarged end A of the post is lodged within the recessed portion 6 of the cap as indicated in Fig. 1.
'hile'the enlarged head of the post may or may not be threaded I prefer the latter construe-tum for the reason that the annular-cap cannot then be disengaged from the post without first introdui-ing the threaded head into the threaded portion of the cap, even though the cap nut may have been first removed. i
Having thusdcscribcd my invention, what I claim 1'. An electrical terminal comprising a post haviiig an enlarged head at one end, anannnlar cap mounted thereon provided with transverseopenings and recessed to re-' threaded stem adapted tion inthe presence ceive the head of the 30st whereby the cap may be rotated upon the post to change the radial direction of the transverse openings in the cap with respect to the post, and a capnut provided with a projecting stem having a screw threaded engagement with the annular cap whereby it may be brou ht into impinging relation with the ends of the electrical conductors lodged in the t'ansverse openings of the cap.
2. An electrical terminal comprising a screw-threaded post having an enlarged screw threaded head at one end, an annular cap with t ansverse openingsto receive electrical conductors and tapped at one end to receive the enlarged screw-threaded head of the post, the opposite end of the cap providcd with a smooth bore through which the post projects said cap having also an intermediate rece, 1 portion between. the tapped portion and its smooth bore to receive the head of the post in which it is free to turn, whereby the cap may be rotated upon the post without changing its longitudinal adjustment, a cap nut provided with a pro jetting stem cngagii1gthe tapped portion of the annular cap, and a lock nutengaging the post to secure the post in position.
3. An electrical terminal comprising a screw-thi-oaded post carrying an annulaneap at one end, said cap provided with a pinrality of transverse openings to reeeivethe ends of electricalconductors and also tapped to receive the stem of a cap nut, the cap nut provider] with a head overlapping the end wall of the annular cap and having a screwto engage the ends of the electrical conductors lodged in the transverse openings of the annular cap, the 0verlapping head of the nut being adapted to engage a conductor lodged between the head of the nut and the wall of the annular cap, and a lock nut tapped to receive the post.
4. An electrical terminal comprising a post carrying an annular cap at one end, said cap provided with a plurality of transverse openings to receive the ends o f electrical conductors engaged therewith and also tapped to receive the stem of a cap nut, and the cap nut having a screw threaded pro- .jccting stem designed to engage the.electrical conductors lodged in the transverse openings of the (lil]) .7-Silld cap nut also provided with a central longitudinal boreto receive an electrical conductor inserted through the aid cap nut. imon-y whereof,-I sign this specificaof two witnesses.
