l""f""-Be`it known that I, HARVEY E. PHiLLirs, 'a' citizen of the United States, residing at "UDe'ftroit, county of Wayne, and tate of ,Michigan, have' invented certain new and useful Improvements in Binding-Posts, of vvhich the following is a "act description.

i This .invention relates to improvements in binding or terminal posts for securing the terminals of connectors, or clips. of any type,

" firmly in` position, but which. permits the ready detachment of the connector or clip j from the binding post. lUne of the ob]ects of this invention is to so combine the elements thereof that the structure will be simple and compact, and especially adaptable to be used in places, 1 wherein economy of space is desired or es- 2gofsentialj f Another object-of the present invention to provide a binding post, which Will facilitate the application and removal of the Connectors 'or clips therefrom. 2'5 A further object of the present invention is to so combine the terminal post and the clip or connector, to be secured thereto, that thef'saidelip'or connector will be positively docked' or latched in applied position, thus "preventing the accidental removalof said clip, and also preventing the inadvertent `idisplaCement thereof.

Astiil further object of the present invventionis to provide means for permitting *the movable element or elements of the bind-V iiigpostrto be withdrawn from their nor- "inal' esition and maintained in an inoperaposition, thus facilitating the applicaiaiidfremoval of the elips,'to and from hers'ai'd p'ost.

. With the above and incidental objects in vieit`,"t`here is shown in the accompanying "drawin a preferred form of one embodim resent invention, a detail de- 'shriptionof which will now be given.

Fig. 2 is view in side elevation of the terminal post fziliown in Fig. 1.

Fig. 3 is a view in elevation of a modified form of the terminal post shown inlFigs. l and 2. x

Fig. 4 is a View similar to Fig 3, but showing the movable element of the terminal post in inoperative or non-clamping position.

Fig 5 is a perspective View of one form of the terminal clip embodied in the present invention. 1

In Figs. l and 2, it will be seen that the binding post comprisesa central rod or stud 20, having a fiange or projection 21, formed intermediate the ends thereof and providing a base'for the' spring pressed cap or sleeve 23, of the upper clamping element or hinding post. j

This cap or sleeve iscounterbored, as at 24, and has the spring 25, seated in the counterbored portion. A shoulder formed by counterboring said sleeve, acts as one abutment .f Jr the spring 25, and the plate 26,

which is secured to the extremity of the, stud 20, constitutes the opposite abutment.

From this construction, it will be seen that the spring normally maintains the cap or sleeve 23 in Contact with the shoulder 21,

or atleast, in contact with what maybe termed the locking shoulder 27, which may be formed integral with the lian e 2l.

The binding post described above is adapted to be employed in conjunction with a novel type of terminal clip; the novel features thereof being set forth her, ,inafter. This terminal clip comprises a. shank portion 29, provided with the head portion 30, wherein an annular openingl, havingan entrance opening 32, isA formed.

Inorder to secure the terminal clip 28 ,against accidental removalfrom its applied position, thediameter of the opening 3l is made slightly greater than the diameter of the locking shoulder 27, but less than the diameter of the flange 21,` while the diameter uortion ofthe stn'd 20, the sleeve 23, but is which is surrounded' y 32 is greater than' hel which is a A'as :a means for securing tiltmalv c ar'nping.4 element.

less tlian the diameter ofthe locking shoula er 2 j In the resent invention a' further locking effect as been secured by having a projection or in 33, secured to the {lange-21, pted to fit within the slot 34, formed in the adjacent clamping' face of the sleeve' or ca 23. v f' The terminal clip 28, is also recessed as at 35, so that the pin 33 will [it within the recessed portion 35, when the terminal is applied to the binding post.

`Under certain conditions, it has been found advisable to rovide some means, 'whereby the c'ap or eeve 23 may be held out of operating orclampinp position, in

order to facilitate the remova or the appli- .Y

' i ed on t e movable sleeve or clamping elecation of terminal clips to-,tle post. .The provision ofthe pi 13.3 notonly acts nd maintaining the terminal clip in its applied position, but it also rovides the aforementioned `means for holding the cap 23 out of operative' posiis raised Yabove the pin 33, and turned so t at the slot 34 thereof, is removed from alinement with the in, the' cap may be released and will be dp'in raised. position by engagement with the-.pin 33. In Fi 1 and 2, there is shown an addi- This clamping element is insulated from the structure'heretofore described, so that an electricalcn- .nection ma belmade, which may be absolutely insu ated from 'and independent of 'the electrical connection secured byhthe outer clamping element. The central stud 20 is, in the `present instance, surrounded by an insulated .sleeve 41, which has at one end, thewasher or head '42, one face of which lies adjacent to the washer 21% The'op osite faceV of this washer' 42 carries a meta facin 44,. which forms. a bea-ring element for t e reduced end 45 of the movable sleeve 46.` A metal tube 47, surrounds a the said sleeve 41,l and is reduce as at 48, thus forming the shoulder 49, which furnishcs'one abutment for thel spring 50. -V This spring is mounted in the reduced portion of the metal sleeve 47 and tendsto `normally maintain the movab in 'contact with the metal yfacing 44 of the washer 42. The movable sleeve or clampin elcment46 has an internal flange, as at 5 which forms -an' abutment, against which y,

the spring normally presses, whereby this sleeve, as above stated, ismaintained in contact with the.' metal. facing 44 of the washer 42.

A In. abinding post ofv this type, a locking shoulder '52,is formed on the movable sleeve or clamping'clcment, by reducing the clamping end thereof, as at 45, so that the termiits mainY o eningof' .inventionortion of le sleeve 46,*

nal clip which is used in conjunction with' this portlon ofv the binding post, must have Y' the` reduce 'portion o,

than the iameter of'ths reducedportion 45, but of 'greater diameter than the cross sectional dlameter of the -metal tube, upon eater diameter than ithe sleeve, while theI entrance o ening 'must Abe of less diameter which the movable .sleeve is mounted and which in reality forms .the electrical connection.

It will, of course, be understood that this particular construction of the binding post may be provided with a lockingpin to cooperate with a recess formed in thev terminal clip, if"it.`1s so desired, it simply being necessa that, the locking pin 53 be mounttrical connection with any circuit to which th'e body ofthe binding post may be connected...

The structure of the post shown in l i is substantially the same as thatdescr in connection with the description ofthe similar elements included in Flgs. 1 and 2, and therefore, no further detailed description is deemed necessary.

While I have shown preferred forms of embodiment of the present invention, it

should be understood that various changes and modifications of the elements` and combinations of elements, comprising the present invention, may' be made without departing from the Spiritand scope of the present.

What I claim is as' follows: I- 1. In a 'binding postthe combination with a plurality of slidable clamping elelos ments; of a' stationary element' resilient.
