It comprises a bridge having contact means that positively engage, and is embedded into, the terminal post and the terminal clamp; thus assuring continuity of current through the system, by bridging the corrosive condition.
4 Claims, 3 Drawing Figures BATTERY TERMINAL BRIDGE BACKGROUND OF THE INVENTION 1 Field of the Invention This invention concerns a means to be mounted over the terminal post and cable clamp of a battery to remedy the situation where the mutual engaging surfaces of the post and terminal clamp have become corroded so as to reduce, or entirely interrupt, the flow of current in the system. This device is especially helpful for use by service men when called to service an automobile having corroded terminal connections.
2. Description of the Prior Art The applicant is not presently aware of any similar device that will accomplish the objects of the present device.
SUMMARY OF THE INVENTION This invention comprises a bridge or bracket of conductive material that embraces the terminal clamp of a battery. A contact member is positioned in the bracket on each side of the clamp, and which members are adjusted so as to become embedded into the lead of the clamp. A contact member is also positioned in the bracket approximately on the axis of the terminal post and which member is embedded in the upper end of the post. An object of this invention is to provide a means that will permit the current from the battery to by-pass the corrosion between the post and the terminal clamp and assure an uninterrupted flow of current through the system.
Referring to the drawing:
FIG. 1 is a plan view of the device as assembled on the terminal of a battery.
FIG. 2 is a front view of the device, and showing the means of assuring a positive flow of current from the post to the terminal clamp.
FIG. 3 is a modification of the means of clamping the device on the post and terminal clamp.
The preferred form of this bridge is indicated at 10, which is preferably of steel and is mounted over the terminal post 12 of the battery 14. The post 12 has assembled thereon the standard terminal clamp 16 which engages the tapered post 12, and is provided with a cable 18 of the usual type.
The preferred form of the bridge comprises a transverse portion 19 having vertical, downwardly-extending arms 20 and 21. This bridge is of a substantial thickness to resist excessive spreading of the arms when the device is being mounted.
A contact screw 22 is threaded into the transverse portion 19 at a central position thereof, and is provided with a cone point to permit it to be embedded into the end surface of the post 12. Similar contact screws 24 and 26 are provided in each of the arms 20 and 21.
When a corrosive condition occurs between the mutually-engaging surfaces of post 12 and clamp 16, the bridge 10 is placed over the clamp 16 as shown in FIGS. 1 and 2. Contact screw 22 is initially positioned approximately at the center of post 12 so that screws 24 and 26 can engage the clamp 16 approximately as shown in FIG. 2. Contact screws 24 and 26 are then unifomily turned toward clamp 16 until the cone points thereof are deeply embedded in the sides of the clamp, as shown in FIGS. 1 and 2. Screw 22 is then similarly adjusted so as to embed the cone point thereof deeply into t u er surface of 0st 12.
It wi ll b e obvious that urrent will now flow positively from post 12, through screw 22, along portion 19 and arms 20 and 21, through screws 24 and 26, and then into clamp 16, and finally through cable 18: thus bypassing the mutual corroded surfaces of post 12 and clamp 16.
FIG. 3 shows a modification of the form of a stud 28 which is substituted for screw 24. This modification may be preferred in some instances.
The above being a complete description of an illustrative embodiment of the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is:
1. In combination with a battery having a post, and a terminal clamp secured to said post, a means to electrically by-pass a corrosive condition between the mutually-engaging surfaces of said post and said clamp, comprising a bridge having a transverse portion traversing said post and said clamp and terminating in arm portions directed toward said battery, contact means in said transverse portion adjustably embedded into said post and contact means in each of said arm portions to be adjustably embedded into the surface of said clamp.
2. The combination as set forth in claim 1, in which said contact means comprise threaded members.
3. The combination as set forth in claim 2, in which said threaded members terminate in cone points.
4. The combination as set forth in claim 1, in which one of said contact means in said arm portion comprises an integral fixed member.
