CARBON BATTERY.

JOHN B. \VALLAOE, OF ANSONIA, CONNECTICUT, ASSIGNOR TO THE ELEG- TRIOAL SUPPLY COMPANY, OF SAME PLACE.
cARBoN BATTERY.
SPECIFICATION forming part of Letters Patent No. 392,836, dated November 13, 1888.
Application filed September 3, 1888. Serial No. 284,474. No model.)
To all whom it may concern;
Be it known that I, JOHN B. WALLACE, of Ansonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in Carbon Batteries; and I do hereby declare the following, when taken in oonnection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same,
and which said drawings constitute part of this specification, and represent, in-
Figure 1, an under side view of the cap; Fig. 2, a vertical section through the cap; Fig. 3, ahorizontal section through the recesses and 1 carbon, illustrating the clamping of the carbon between. the screw and the bearing-points in the recesses; Fig. 4, a modification in the formation of the bearing-points in the recesses.
-This invention relates to an improvementin.
that class of carbon batteriesin which the carbons are held suspended in the cap of the jar by their upper ends and stand surrounding the zinc. In the best method of manufacturing the caps which support the carbons they are 2 produced from east metal,the cap being adapted to set closely upon the jar, and upon the under side of the jar recesses are made in position for the several carbons, and into which the upper end of the carbon may set. In molding these caps the recesses are necessarily tapering, in order to permit the pattern to draw readily from the sand. Upon the outside of the cap screws are introduced, entering the recesses radially, and so as to bear directly upon the 5 carbon; but unless the carbons fit their respective recesses perfectly the bearing of the screw upon the carbons will throw them out of line, so that they-will not stand parallel with each other and parallel with the axis which they surround, and the carbons will make imperfect contact with the top and thereby effect the external resistance. It'is therefore necessary that the carbons shall be properly seated in the cap. To fit the carbons to the respective recesses, and so as to insure a good electrical contact, requires a very considerable amount of time and careful labor.
To obviate these difficulties and properly locate the carbons is the object of my invention;
and it consists in constructing the recesses with two or more bearing-points opposing the screw,
and so that the carbons will be clamped in the recesses between the said points and the said screw, and as more fully hereinafter described.
A represents the cap, which is of usual construction, adapted to set upon the jar and provided at its center with an opening, a, for the support of the zinc. Concentrically around this central opening the several recesses b are made to receive the carbons. In casting the cap these recesses are made by projections on the upper side of the cap, as seen in Fig. 2, and in order that the pattern may draw readily from the sand the recesses are made taperingthat is, of smaller diameter at the closed end of the recess than at the open endand, as clearly seen in Fig.2, each recess is provided with a set-screw, B, introduced from the outside, which enters radially into the recess, as seen in Fig. 3. To properly seat the carbon in these tapering recesses, I form projections 11, preferably two, opposing the set-screw B, as seen in Fig. 3, andpreferably equidistant from each other and from the screw, so that the screw and these two projections form three points between which the carbon may be clamped. These projections are constructed to bear upon the carbon in a plane with the screw, and may be formed in various ways say as in the process of casting, so as to leave ribs upon the inside, as represented in Fig. 2, or by indentations made from the outside inward, as seen in Fig. 4, so as to produce the required projection d upon the inside of the recesses. The end of the carbon is introduced into the recess in the usual manner and the screw set thereon so as to clamp the carbon between the said bearing-points in the recess and the said screw, and because of these bearings being directly radial upon the carbon and in a plane at right angles to its axis the carbons will all stand parallel with each other and in their proper relation to the central member of the battery.
From the foregoing it will be understood that I do not wish to be understood as limiting my invention to any particular method of making the projections which form bearings between which and the screw the carbon is clamped, but
WVhat I do claim as my invention is-= A cap for carbon batteries, having recesses formed upon the under side to receive the'en-ds bearing-points and the said screw as a means of the carbons, combined with aset-screw from for supporting the carbons in the cap and a the outside radially into the said recesses, and good electrical contact insured.
the said recesses constructed with two or more JOHN B. WALLACE. 5 bearing-points upon their inside opposing said Witnesses:
screw, substantially as described, and whereby JOHN E. EARLE,
the carbon may be clamped between the said FRED (l. EARLE.
