dlllTNl-ISSES: 7 INVENTOR fior/ 6. Awzda/l I BY mt. 01mm, or ,Enenwoon rnnx, mmvsnvnnm, ASSIGNOR 'ro wnsrmenousn ELECTRIC AND manomcronme comm, a conromnon or rmmsnvsma, r
of Edgewood Park, in-the county of A1le-' 6 gheny 'and'State of Pennsylvania, have in- .vented a new and useful Improvement in Binding-Posts, of which the following is a specification.
My invention relates to binding posts and partlcularly to binding posts for fuse blocks. The object of my invention, is to provide a binding post .of the'above indicated characterwhlch shall preclude the necessity of providing clip terminals for the ends of fusible conductors that are attached thereto. Heretofore, fusible conductors have been provided with clip terminals for preventing the same from belng squeezed into a smaller 1 cross section and thus made liable to melt when subjected to a current which is smaller than the normal fusing current. Since it has been found expensive to rovide fusible conductors with clip termina s, I have pro vided a binding post which obviates the me cessity of the same.
In the accompanying drawing, Figure 1 is'a fragmentary plan view of a binding post embodying my invention; Fig. 2 is a fragmentary view, partially in elevation and bodies my invention, comprises a base mem-.
as ber 4, a clamping member 5, and a screw threaded member 6, substantially as shown in the drawing. The base member 4 is usually formed of sheet metal, substantially as shown in Fig. 5 of the drawings, and is sheared along the line VII-VII for a cer tain distance and folded to form a projection 8 .(Fig. 6). A hole 9 is provided in the member 4' through which the screw threaded member 6 may be. inserted.
to The clamping member 5' is substantially partially in section, of the device shown in: Fig. 1; Fig. 3 is a detail plan view of a BINDING-POST.

elliptical in shape and portions of the same are cut away to form two spaced-apart arms 10, for reasons hereinafter set forth. The member'5is provided also with an opening 11 through which the screw threaded memher 6 is inserted, and its under surface is chamfered to prevent the fusible conductor 3 from being squeezed into a smaller cross section when it is subjected to pressure. The fuse block -1 is provided with-asocket 12 having a screw hole 12- therein for the reception of-the screw threaded member 6. The screw threaded member 6 is provided with an enlarged head 13 that is slotted to receive a screw driver.
' The projection 8 is disposed between the arms 10 of the clamping member 5, and the screw threaded member '6 is inserted in the holes 11 and 12, substantially as shown in the drawing. The fusible conductor 3 is inserted between the clamping member 5 and the base member 4 and is twisted around the screw threaded member 6, substantially as shown in Fig. 1 of the drawing. The projection 8 .prevents the fusible conductor 3 from becoming doubled upon itself between the clamping member 5 and the base memher 4 which would tend to decrease its cross section when subjected to pressure from the clamping member 5. The clamping memher 5 is forced downwardly when the screw threaded member 6 is screwed into the hole 12 and is prevented from rotating by reason of the engagement of the projection 8 and -the arms 10. The fusible. conductor 3 is thus clamped to the binding post 2 to make a good electrical contact. The member 5 is chamfered at its under side to prevent the conductor 3 from being squeezed off when the member 5 is clamped in position, as was hereinbefore described.
Of course myinvention is not limited to the particular construction illustrated, but is capable of various modifications within the scope of the appended claims.
I claim as my invention:
1. A binding post comprising a base member having a projecting ear, a clamping member having two spaced-apart arms disposed one on either side of the projecting ear and having chamfered edges, and means for securing the clamping member to the base member.
- 2. A binding post comprisinga base memher having a laterally-extended portion, and 1.10.
a clamping member having two spaced-apart arms between which is disposed the laterallyextended portion of the base member, the
- edges of the spaced-apart arms adjacent the base member being ehamfered.
3. A binding post for a fusible conductor comprising a base member having a laterally-extended portion, and a clamping member having an opening therein for registering with the laterally-extended portion, said clamping member being chamfered at one of its edges to prevent reducing the cross-sectional area of the fusible conductor.
4. A binding post for a fusible conductor comprising a base member having a laterally-extended portion, and a clamping member having an opening therein for registering with the laterally-extended portion, said clamping member being chamfered to prevent reducing the cross-sectional area of the fusible conductor, the laterally-extended portion of the base member being provided to prevent the doubling of the conductor between the base member and the clamping member and to prevent the clamping'memher from turning.
In testimony whereof, I have hereunto subscribed my name this 22nd day of May, 1914.
