CONE SCALES FOR SAVING GOLD.


vented BY 4 CslkernisA.

Charles rrafton of Yankee Jim's.
Placer county, has just patented
through the Mining and Scientific
Press Patent Agency . new gold.
saving apparatus. the mai" feature OF
which consists in the novel concen.
tratins OF Rold-catch'ng surface.
He makes frame or table of any
suitable character, over tho surface Of
which are secured the scGles Of the
cones of the coniferm order. For
some work--as, for instance, for
cosrser m.terial-he prefers to use
the scales of the larger CONES, such a.
are borne by tho "digger" and the
sugar pine. For lighter work he uses
the scales of smaller cones, and OF tn q
spruce, and In some instances the
scales Of the cones Of the fir and hem.
lock. These scales are closely set
over the surface Of the frame or table,
some what after the manner of shin.
giles, though not necessarily 10 the
regular rows or lines Of shingles, bu,
in such way as to fully cover the
frame OF table surface, the scales
overlapping each other. They may
be secured upon y perfectly plane sur.
face, OF upon surface formed with
incllnes.
In either csse-on account Of the
peculiar shape OF the scales-.hey dc
not lie Hat aud close upon ono another,
rs 10 shingles, but their free points
OF ends are separated from the bodies
Of the scales which they overlap, and
especially is this separation noticeable
where the scales are set 70 break
joints, - it were, in succeeding rows
because Of the lateral convex kitty OF the
scale, = space being lett between the
points OF the overlapping scales and
the meeting edges Of the u"derlyin
scales. This separation is more no.
tioeahle, however, in tho form where
the scales are attached TO ,nolines
The surface thus provided 10 . very
rough one, having deep i"terstice'
and spaces.
The utility of the surface for tn,
purpose i, tended lies in this fact to ,
great extent, as the heavier pArticle'
are caught In the interstices OF spaces
be, ween the scales, which thus form
rifles. while the lighter particles sr'
washed off, it being understood ths

The table or frame Is intended 4
be one of series OF similar tables O
frames to be placed in thu sluio-; bu
it is obvious that the same surfac

sides sufficiently high to form q chan

face i not confined, however, to i,
rouKhness. but 10 due also to y pr

itself after wear.
The upper OF outer surface OF tn
