COMBINATION BINDING-POST.
Specification of Letters Patent.
Application led August 9, 1911. Serial 1N0643,173.
To all whom it may concern:
Be it known that we, (l) Pnnmnj H. Carrer and (2) Louis F. MCCnnanY, citi.- zens -of the United States of America, residing at- Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improve- 'ments in Combination Binding-Posts, of
which the following is a specification, reference being had therein to the accompanying drawino.
This invention relates to a combination 'binding post` particularly designed for terminal heads in electrical construction, for instance, as cable boxes.
The primary object of our invention is the provision of positive and reliable means, in a manner as will be hereinafter set. forth, for connecting the wires upon one side of the terminal head to those upon the opposite side, the connection being of suclrform that it. will withstand jarring and vibration and save time and money in the construction of new terminal heads'and the repairing and testing of those already in use. l
A further objectof our invention is to furnish a binding post with permanent wire holders or clips-that reduces the resistance in a line to a minimum and assures a. ready and convenient means of connecting` wires of branch circuits.
Terminal heads are constantly subjected to jars and vibrations in many places which loosen the nuts on binding posts now in use, causing poor connections, increases the line resistance and in many instances itis necessary to install new wires and these new wires are greatly weakened on account of the 4such bending which is now necessary to make4 the connections. Furthermore, in testing out a able it is often found that loose connections on the inside of the terminal head, in order to repair the damage, it is necessary to take off the front plate which is held by a number of screws, consequently considerable time and labor is consumed.l Still further, in the present type of binding post is necessary to wrap the wires around the screws, thereby weakening the wire and .sing breaks that interfere with th, succx nil 4pei-ation of the terminal head, prt larly in a cable box.
ille obviate the above defects by a binding post that can be advantageously used `in connection with the cable box, the inner terminals being :made permanent whereby it will be unnecessary to open the cable box, particularly when the wire trouble can be easily observed upon thel exterior thereof.
The invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, where- Figure 1 is a perspective View of a portion of the cable box provided with a combinatio'n binding post in accordance with this invention. Fig. 9. is a side elevation of the binding post. Fig. 3 is a vertical sectional view of the same, Fig. 4E is an enlarged side elevation of a modified forni of post, and
Fig. 5 is a longitudinal sectional view of a' modified form of binding post.
A post in accordance with this invention comprises a bolt l havingone end thereof screw threaded, as at 2 and the opposite end thereof provided with an integral head 3, said. head being removed from the ex,- treme end of the bolt l, whereby the eX- tremity can be provided with Hat faces L and with a transverse opening` 5. The opening 5 is adapted to receive the end of a wire or an electric conductorl 6 and to retain the end of a wire in engagement with the post, a C-shaped clamping member or clip 7 is employed. 'ln the preferred form of construction, the cli-p has one end thereof integral with the head 3 and the opposite end is longitudinally slot-ted, as at 8 and bent to form a finger grip 9. The slot 8 provides clearance for the lower end of the bolt l and 'said clip is depressed or shifted toward the head 3, whereby the end of the wire 6 can be inserted in the opening 5. Then by releasing the clip, the resiliency thereof is adapted to hold the clip in engagement with the wire and retain the wire in engagement with the lower wall of theV opening 5.l ln this manner the wire is detachably held, yet a positive connection is made between the wire, clip and bolt. The head 3 and the clip 7 constitute an inner terminal that maintains a connection under the most trying circumstances, thereby obviating an examination of the inner terminals, particularly when used in connection with a cable box l0.
As illustrated in Figs. l to 3 inclusive, the bolt l extends through insulations 1l arranged in the wall l2 ofthe cable box, and detachably mounted upon the upper screw threaded end of the bolt l is a nut 13 having an integral clip or clamping member 14 roo similar to the clip or member 7. The nut 13 has a stein 15 with flat faces and with transverse openings ltand 17, said stemrepreseiitiiig a continuation of the bolt 1. The wire 1S is adapted to be retained in the opening 1G by the clip or clamping member 14, and when it is desired to insure a more positive connection, the end of the wire 18 can be bent and carried into the opening 17. It is unnecessary to wind the end of the wire around the stem 15, as the manner in which the wire is connected to saidstem insures a positive connection. After the nut 13 has been positioned upon the bolt 1 and the wire 1G connected to the stem 15 by the clip or member 14, the nut 13 cannot rotate on account of the side walls of the slot of the clip engaging the flat sides of the stem 15, consequently the nut 13 cannot become accidentally displayed and serve functionally as though it were a permanent part of the post. It assures an easy path`for the flow of an electric current and eliminates the resistance of the connection which heretofore has caused considerable trouble. rl`he nut 13 is rectangular for the convenience of loosening and tightening the binding post.
In Fig. 4 of the drawing there is illiistrated a modification of the invention, wherein the clip or clamping member 19 is made detachable and is heldbetween the head 3 and a Washer 20.
The modification illustrated in Fig. 5 consists of two clips 2l and 22, the clip 22 being arranged within the clip 21. vThe clip 22 has a tongue 23 extending into the slots 24 and 25 of the clips 22 and 21 respectively. This tongue is adapted to hold a wire 26 between the clips 2l and 22, and to bind the clips together-upon the wire 26, a pin 27 is inserted between the tongue 23 and the clip ln lieu of the pin 27, the end of the wire can be bent to pass between the clip 22 and the tongue 23. The advantage of this construction is that a positive connection is made between the wire 26 at more than one point and the danger of leakage is removed. i
From the foregoing it will be observed 'that the binding post comprises two parts l. In a binding post, a bolt, a resilient clip formed integral with one end of said bolt and adapted to retain a wire in engagement witli'said bolt, a nut screwed upon the opposite end of said bolt, a stem carried by said nut, and a resilient clip formed integral with said nut and adapted to retain a wire in engagement with said stem.
2. In a combination binding post, a bolt, a head carried by one end of said bolt, a resilient clip formed integral with said head and adapted -to retain a Wire in engagement with said bolt, a nut screwed upon the opposite end of said bolt, a stem carried by said nut, and a resilient clip formed integral with said nut and adapted to .retain a wire in engagement with said stem.
In testimony whereof we affix our signatures in the presence of two witnesses.
