Specification of Letters ?atent.
Patented Sept. 12, 1916.
Application filed January 15, 1914. Serial No. 812,267.
1 '0 all whom it may concern Be it known that I, fXLFONSOR. Rrnnnnnnonn, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Ground- Terminals, of which the following is a specification.
An object of this invention is to provide an improvement in terminal rods for electrical conductors, which is simple and inexpensive in construction, efficient in operation and adapted to provide means for securing an electrical conductor to said rod so that it cannot be separated and lost when not in use.
More particularly this invention is an improvement upon the construction of connectors for ground terminals set forth in my companion application Serial Number 537,199, filed Jan, 10, 1910. In the accompanying drawing forming part of this specification, Figure 1 is a side elevation of a detail of a ground terminal showing the connector securing an electrical conductor thereto, a portion of said terminal being in section; Fig. 2 is a section upon the line X X of Fig. 1, and Fig. 3 is a plan of the connector.
In the drawing A indicates a portion of a ground terminal of usual form consisting in the illustration of a rod flattened on one end to form a broad portion 2 having a centrally disposed circular passage 3 through which the connector B is secured. The connector B consists of a bar of electrical conducting material such as metal semi-circular in cross section and bent between its ends, having its flat surface 4 facing inward. This bar being formed as described produces a pair of sides 5 and 6 converging outwardly toward their free ends and adapted to pass freely through said passage 3 and extend beyond the side of the portion 2 of the rod. The median portion forming the curved end 7 of the connector, being larger in diameter than the diameter of the passage 3, prevents the connector passing entirely through said passage. The adjacent fiat portions of the surface 4 of the sides 5 and 6 are formed with a pair of longitudinal grooves 8, which are deeper in the free ends of the sides, gradually diminish in depth toward the inner end of the connector and terminate a short distance from the curved end portion 7. The passageway formed by the grooves 8 is adapted to receive the end of an electrical conductor such as 9 freely when the connector is moved with its free ends back in the passage 3 into receiving position. hen the conductor is adjusted as stated the connector is forced forward with its apex end projecting from the side of the portion 2 of the terminal rod, by pounding or pressing upon the curved end 7, thus wedging the connector in the wall of the passage 3 and securely holding the conductor 9 in close contact with said rod. The outer end of the side 6 of the connector is formed with an enlarged head 10 projecting beyond the end of the opposite side 5, said head being formed by spreading the material of the side and being of suflicient size to prevent the connector passing backwardly through the passage 3 prior to the conductor 9 being in serted in the connector. Before a conductor is inserted in the connector, the connector is disposed freely in the passage 3, the amount of free play longitudinally being limited by the end 7 and head 10.
A connector of the construction described is very simple and inexpensive in construction, it being made out of a. single piece of material which can be formed by a few number of operations in the process of manufacture, and which will produce an efficient electrical connection between the conductor which it holds and the wall of the terminal rod in which it is seated.
In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
Having described my invention what I claim as new and desire to protect by Let-' ters Patent is i 1. In combination with a. ground terminal having a transverse passage therethrough, a connector passing through said passage consisting of a bar bent between its ends to form two sides converging from their connected portion, their outer free ends being freely disposed longitudinally through said passage and adapted to close upon a conductor by wedging in said passage when moved inwardly and the end of one of said sides being extended beyond the end of the other side and enlarged to form a head adapted to prevent the entire removal of said connector from said rod but permitting a limited free longitudinal movement outwardly.
2. In combination with a terminal rod having a transverse passage therethrough, a connector consisting of a strip of conducting material bent between its ends to form a pair of sides converging toward their free ends, said sides being adapted to pass through the passage in said terminal rod, the large end of said connector being larger than the diameter of said passage and the sides of said connector being adapted to receive and clamp an electrical conductor between them when said sides are wedged in said passage, one side of said connector having its outer end extended beyond the end of the other side and enlarged to form a stop, of greater width than the diameter of said passage to prevent said connector being detached from said terminal rod before said electrical conductor is clamped between said sides and so positioned as to allow a limited free outward movement of said connector longitudinally in said passage before a conductor is clamped by said sides and held on said rod.
3. A connector of the class described consisting of a bar bent intermediate its ends to form a curved portion serving as a stop, the sides thus formed gradually converging toward their free ends to close under wedging action, one of said sides extending beyond the companion side and being enlarged to form a stop.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses,
ALFONSO R. RHEINBERGER.
