Complete Specification Left, 11th Feb., 1893-Accepted, 20th May, 1893
PROVISIONAL SPECIFICATION.
Improvements in Electrical Accumulators.
We, BERNARD MERVYN DRAKE and JOHN MARSHALL GORHAM, Electrical
Engineers both of 66 Victoria Street in the City of Westminster, S.W. and WALTER
CLAUDE JOHNSON and SAMUEL EDMUND PHILLIPS Electrical Engineers both
of 14 Union Court London E.C. do hereby declare the nature of this invention to
be as follows:
Our invention relates to an improved method of supporting and carrying
accumulator plates of the laminated type. In plates of this kind it is essential that
the plates be left free to expand lengthwise for which purpose they must not be
tied at the bottom by any rigid method; at the same time it is advisable that the
weight should be carried by a stiff bar which will not cut into the laminated strips
and will at the same time support them and prevent undue sagging. To obtain
this result we continue the solid frames or lugs under the plate on each end, the
plate therefore stands upon these projecting pieces which are either of lead or
nonconducting material such as pottery, the supports are run in with lead in the
course of manufacture. The plates can then be carried by bottom blocks in the
usual way or suspended, but in either case the point of support will be the lower
portion of the projecting piece which lie along the underside of the plate and do
not meet in the centre.
