of difference. Furthermore, I have provided an improved
aligning device for the matrices, designed especially to give
absolute alignment, and one which ordinary wear will not
affect. Another improvement consists in the form of matrix-
or die-case which permits the type being put in the line of
assembly on moving them but a short distance from the place
where they are cast. I have also designed a novel movement
to control the positions of the matrix-case. A still further
improvement consists in providing a set-size index for the
matrix-case. Heretofore the running widths or sizes of the
type have been indicated on the controller, or the same
sizes have been grouped together in the matrix-case. My
plan enables me to utilise the advantages of both the old
methods, &c.

plates.

Claims.—(1.) In ore-concentrators, a table having a series of
lines of trapezoidal riffle pits or pockets each having its base
and sides formed with an undercut recess, said riffle-pockets on
the one line alternating with the surface portion of the table
between two riffle-pockets on the adjacent succeeding line,
and being arranged base towards base, substantially as
described and illustrated, and for the purposes specified.
(2.) In ore-concentrators, a table comprising the subject-
matter of the preceding claiming clause 1, with the provision
of an undercut V-shaped riffle alternating with every two
lines of oppositely arranged riffle pits or pockets, said V-shaped

of undercut riffle-slats g and forming V-shaped riffles, tapering
in length from the “discharge” to the “feed” ends of the
table, substantially as described and illustrated, and for the
purposes specified. (4.) In ore-concentrators, a table a¹ having
a series of V-shaped undercut riffles h, each riffle being of
shorter length than the succeeding one, and having its dis-
charge end curved or rounded off, substantially as described
and illustrated, and for the purposes specified. (5.) In ore-
