STORAGE-BATTERY TERMINAL POST.
Specification of Letters Patent.
Patented Apr. 26, 1921.
Application filed September 21, 1917. Serial no; 192,439.
To all whom it may concern:
Be it known that I, CLARENCE W. Haze LETT, a citizen of the United States residing at Lakewood, in the county of (Juyahoga and State of Ohio, have invented a certain new and useful Improvement in Storage- Battery Terminal Posts, of which the fol lowing is a full, clear, and exact description.
This invention relates to an improvement in plate strap posts for storage batteries. In order to increase the conductivity of strap posts, it has been the practice to cast a copper rod therein. However, the copper rod has always projected from the top of the strap post where it is subjected to corrosion before the connector link has burned it in place. Whenever the tip of the rod is corroded or sulfated, a poor joint is formed when the connector link is burned in position on top of the post.
It also is a diilicult matter to properly burn a connecting link onto a strap post having a copper rod projectin from the top. When the flame is directec on the assembled link and post, the heat is so readily conducted away from the top of the post by the copper rod that the surrounding connector will melt and be ruined before the top of the post is molten enough to properly burn or weld.
It is the object of this invention to avoid these disadvantages by producing a post having the insert completely embedded therein, and the manner in which this is brought about is set forth in the following description and drawings in which:
Figure 1 is a view of the copper insert having one end buried in the lead lug.
Fig. is a plan view of a connecting strap with integral strap posts.
Fig. 3 is a sectional view of a mold for producing the plate strap shown in Fig. 2, the section being taken in such a way as to show the plate on the line A-A.
Fig. is a view of a plate post with the connecting link burned thereon.
In order to cast the insert entirely within the post, I form a lead tip or lug 1 on the end of the insert 2, preferably by casting it thereon. In order to cause the lead to better unite with the insert, I solder-coat or tin it throughout. The lug, which is preferably tapered as shown, is inserted in the conical hole 3 in the lower half 4. of the mold, the upper half 5 having been removed before the ter insertion is made. With the insert 2 thus projecting up into the post cavity 6 in the mold, it will be in position to be entirely surrounded by lead when the mold is filled. hen lead is poured into the mold through the usual gate, it will flow into the cavities 7 to form the plate strap 8 and into the post cavities 6 around the insert rod, where it will melt the surface layer of the lead lug l and weld thereto. The molten lead also melts the solder coating on the insert and integrally unites therewith.
When the plate strap with the integral posts 1s removed from the mold, the insert will be deeply embedded in the posts and entirely surrounded by a thick layer of lead.
When the connector link 9 is placed on the post 10 and the hydrogen or acetylene flame is used to burn the two together, the insert 2 is so deeply embedded within the post that the heat is not conducted away sufficiently to prevent proper burning of the connector. Consequently the top of the post can be readily melted by the flame at the same time that the inside of the connector is melted. The cavity 11 is filled with molten lead during the same operation by feeding a lead strip or wire thereinto in the usual y means of my invention the copper is embedded in the strap post so that corrosion or sulfation is impossible. On account of this improvement, plate straps can be stored indefinitely without there being any danger of sulfating the copper inserts by acid fumes which are always present in a storage batfactory or service station.
-Iaving described my invention, what I claim is 1. The process of making a reinforced storage battery post which consists in embedding one end of a good-conducting metal rod in a lead lug, placing a portion of said ing in a mold for said post and casting lead in the mold around the rod and the remain ing portion of the lug.
2. The process of making a reinforced storage battery post which consists in coating a copper rod with solder, casting a lead lug around one end of said rod, placing a portion of the lug in a mold with the copper rod extending into the post cavity, and casting lead in the mold around the rod and the remaining portion of the lug.
3. A lead plate post for storage batteries,
having a good-conducting insert completely embedded therein.
4. A plate post for storage batteries hav ing a lead body portion substantially circular in cross-section and a good-conducting rod aXiallylocated and completely embedded therein.
A plate post for storage batteries comprising a lead body and a substantially central axially-extending rod of good conducting material embedded therein.
6. A. plate post for storage batteries comprising a substantially solid lead body portion substantially circular in transverse cross-section, and a substantially central, axially-extenCing straight rod of copper completely embedded therein to improve the conducting qualities of said post and also to reinforce the same.
