An Improved Ore Stamp.
1, JAMES HARRIS-JAMES of Grainpound Road in the County of Cornwall Mining
Engineer, do hereby declare the nature of this invention to be as follows:-
Each Battery of Stamp Heads herein referred to is arranged to carry such number
of Heads as may be most convenient for the particular work required but usually
four or six.
Two or more Batteries may be erected side by side and on the same lines
or centres to work from an Axle common to the whole.
A Bed of Timber (A. A. Figs. 1. 2. and 3 on the accompanying Drawings) of the
full length required for the number of Batteries to be erected-is framed to fit upon
the Bed pieces (B. B.) of the Stands or "Horses" (C. C) erected and fixed at each end
of each Battery, which Stands carry the Journals (D. D) in which the Stamps
Axle (E. E.) revolves. Two other pieces of Timber (F. F.) are likewise affixed to the
Bed pieces (B. B) one on each side of the Bed (A. A.) the whole being strongly
bolted together.
Rising perpendicularly from the Bed (A. A.) to which they are securely affixed
or morticed and just within the Stands (C. C.) are side pieces (G. G.) bolted or
secured to the Stands (C. C.).
To the back of the Stands (C. C.) Ranging pieces (H. H.) of similar length to the
Bed (A. A.) are securely bolted or fastened at such height as is necessary to carry the
Bearers (J. J.) These Bearers are of cast iron or other suitable metal or material
and are recessed to receive the Bushes (K. K. K. K.) in which the spindles of the
Stamps Heads work. (See enlarged Drawing Fig. 4.) The ends of the aforesaid
Bearers (J. J.) project at right angles to the body of the same, screw bolts passing
through these ends and so securing the Bearers to the side pieces (G. G.).
The Bushes (K. K.) are of cast iron or other suitable metal, the inner one of
each pair occupying the inner half of each recess in the Bearers (J. J.) the outer ones
occupying the remainder of such recesses-the Bush Caps (L. L.) covering the said
Bushes and kept in position by the Screw Bolts which pass through the said Bush
Caps, the Bearers and the Ranging pieces. Each pair of Bushes has a flange raised
around the upper edge to form a grease or oil cup for lubricating.
The Cams (M. M.) the Stamps Axle (E. E.) and the Journals (D. D.) for carrying
the same are of the ordinary make and for which no speciality is claimed.
The Stamps Spindles (N. N.) which carry the Stamps Heads (O. O.) are of round
Bar iron or Steel and fitted to the Bushes (K. K.) in which they rise and fall and also
revolve.
The Stamps Heads (O. O. Fig. 3.) in which the Stamps Shoes (P. P.) are made
to fit tightly are cast onto the Stamps Spindles (N. N.) a Drift Hole is cast
in each Head (Q) to enable the Stamps Shoes to be driven from the Heads when
required.
The Lifters, fixed on the Stamps Spindles (N. N.) for the purpose of raising the
Stamps Heads (O. 0.) by means of the revolving Cams (M. M.) are arranged as
follows:-a Ring of wrought iron or steel is shrunk on hot to the Spindle (N.) just
beneath the Cotter Hole (R.) which passes through the said Spindle. Beneath this
Ring (S) and sliding tightly on the Spindle is an iron or steel Cap (T.) (see detail
Drawing Fig. 5. which shews the plan, front and side view). The lower part of this
Cap is disc shaped, having two bolt holes and Cotter hole (U.) at right angles to the
hole. passes
bolt holes passing horizontally through the disc. A corresponding cotter

page_text: through the Spindle to carry the Cotter (V) which holds the Cap (T.) closely up
to the Ring (S). The Cotter (W.) passing through the cotter hole (R.) gives extra
stability to the Ring (S.).
Placed immediately below the Cap (T.) is a series of thin Discs of Wood or other
suitable material (X. X. X. X.) these Discs are in halves and have a hole in the
centre to allow the Spindle (N.) to pass through, also Bolt Holes as shewn.
Beneath the Discs (X. X. X. X) and sliding tightly on the Spindle (N) is the
Lower Disc (Y.) of iron or. Steel, and having Bolt Holes exactly corresponding to
those in the Discs (X. X.) and the Cap (T.) the part of the holes to carry the bolt
heads being recessed upwards, so as to allow the heads of the Bolts to rise clear of
the lower face of the Disc (Y.) on which the Cams (M. M.) act. The Screw
Bolts (Z. Z.) pass upwards through the lower Disc (Y.) the Discs (X. X.) and the
Cap (T.) the whole being tightly secured by the screw Nuts on the upper face.
By this arrangement of the Lifters, compensation in the amount of fall of the
Spindles, by reason of the wear on the Stamps Shoes, can be made, also the lift can
be varied by using more or less of the Discs (X. X.).
The "Cover or Box in which the Stamps Heads (0.0.) and Stamps Shoes (P.P.)
act, is formed on the front of each Battery by two cast or wrought iron or steel
plates the upper one (a. a.) Fig. 1 and 2.) being a plain oblong plate and bolted
through the side pieces (G. G.) a similar plate (b. 6.) is fixed to form the back of the
"Cover" and held in position by the same Screw Bolts.
The lower Front plate (c. c.) has an oblong opening along the centre of the same in
which the Grate Frame (d. d.) fits closely, the screw Studs, having screw and Nut ou
the outer ends, being screwed into the plate at (e. e.) to carry the Grate Bar (f. f.)
which Bar has a loop at each end through which the Studs (e. e.) pass. The screw
Nuts on the Studs thus holding the Grate Frame (d. d.) in position the Grate.
Bar (f.) impinging on the projecting convex ends of the same.
Placed on the inner side of the lower Front Plate (c. c.) is a second plate (g. g.) of
similar size, but the opening for the Grate Frame, is of the same dimensions as the
inside measurements of the Grate Frame, thus forming a rebate for the same. The
inner plate (g' g¹) is bolted to the outer one (c. c.) the bolt holes being so arranged as
to render the inner plate reversible when desired, the outer plate being bolted or fixed
to the side pieces (G. G.).
A pass plate (h. h.) similar in all respects to the lower front plate (c. c.) is affixed
to the side pieces (G. G.) to form the back of the "Cover," and at the same level as
the front plate (c. c.).
Within the "Cover" of each Battery and of size suitable for the number of Stamps
Heads in the same, is a Foundation plate (j.j) of cast iron or other suitable material
bedded flat and secured by lugs and screw bolts to the Bed (A. A.) This plate has
a rib raised around the upper edges, to contain within the ribs and on the upper
surface as many sole plates (k. k.) of iron or steel as there are Stamps Heads,
and in such position that the sole plates shall be on the same vertical centres as
the Stamps Heads.
The Stamps Grate (l. 1) is held in position between the rebate formed around
the oblong opening in the plate (9. g.) and the inner edge of the Grate Frame (d. d.).
Having now described the nature of my invention, I claim as novel the construc-
tion and arrangement of the Bearers (J. J.) and the Bushes (K. K.) and the Bush
Caps (L. L.) singly and collectively.
Also the construction and arrangement of the "Cover," with the upper front
plate (a. a.) the lower front plate (c. c.) the upper back plate (b. b.) and the pass
plate (h. h.) Also the arrangement of the Grate Frame (d. d.) the Grate Bar (f.f.)
and the Studs (e. e.) collectively with the second plate (g. g.).
. Also the construction and arrangement of the foundation Bed (A. A.) the
pieces (F. F.) the side pieces (G. G.) and the Stands or Horses (c. c.) collectively
and as a whole.

page_text: I also claim as novel the construction and arrangement of the Lifters on the Stamps
Spindles including the various parts thereof singly and collectively and as set forth
in this Specification.
Also the construction and arrangement of the Foundation plate (j. j.) and the
method of securing the same in connection with the Bed (A. A.).
COMPLETE SPECIFICATION.
An Improved Ore Stamp.
I, JAMES HARRIS-JAMES of Grampound Road in the County of Cornwall, Mining
Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
Each Battery of Stamps Heads herein referred to is arranged to carry such number
of Heads as may be most convenient for the particular work required but usually four
or six. Two or more Batteries may be erected side by side and on the same lines or
centres to work from an axle common to the whole.
A Bed of Timber (A. A) as shewn on the Drawings left with the Provisional Speci-
fication Figs. 1. 2 and 3) of the full length required for the number of Batteries to be
erected is framed to fit upon the Bed Pieces (B. B.) of the Stands or Horses (C. C.)
erected and fixed at each end of each Battery, which Stands carry the Journals (D. D.)
in which the Stamps Axle (E. E.) revolves. Two other pieces of Timber (F. F.) are
likewise affixed to the Bed pieces (B. B.) one on each side of the Bed (A. A.) the
whole being strongly bolted together.
Rising perpendicularly from the Bed (A. A.) to which they are securely affixed or
morticed and just within the Stands (C. C.) are side pieces (G. G.) bolted or secured
to the Stands (C. C.).
To the back of the Side pieces (G. G.) Ranging pieces (H. H.) of similar length
to the Bed (A. A) are securely bolted or fastened at such height as is necessary to
carry the Bearers (J. J.) Those Bearers are of cast-iron or other suitable metal or
material and are recessed to receive the Bushes (K. K. K. K.) in which the Spindles
of the Stamps Heads work (See enlarged Drawing Fig. 4.) The ends of the afore-
said Bearers (J. J.) project at right angles to the body of the same-screw bolts
pass through these ends and so secure the Bearers to the Side pieces (G. G.).
The Bushes (K. K.) are of iron or other suitable metal, the inner one of each pair
occupying the inner half of each recess in the Bearers (J. J.) the outer ones occupying
the remainders of such recesses-the Bush Caps (L. L.) covering the said Bushes
being kept in position by the Screw Bolts which pass through the said Bush Caps, the
Bearers and the Ranging pieces. .
Each pair of Bushes has a Flange raised around the upper edge to form a grease or
oil cup.
.
The Cams (M. M.) the Stamps Axle (E. E.) and the Journals (D.D.) for carrying
the same are of the ordinary make and for which no speciality is claimed.
The Stamps Spindles (N. N.) which carry the Stamps Heads (O. 0) are of round
Bar iron or steel and fitted to the Bushes (K. K.) in which they rise, fall and revolve.
The Stamps Heads (O. 0.) Fig. 3. in which the Stamps Shoes (P.P.) are made to
fit tightly are cast on to the Stamps Spindles (N. N.) a drift hole is cast in each
head (Q) to enable the Stamps Shoes to be driven from the Heads when required.
:
The Lifters fixed on the Stamps Spindles (N. N.) for the purpose of raising the
Stamps Heads (0.0.) by means of the revolving Cams (M. M.) are arranged as
follows: A Ring of wrought iron or steel is shrunk on hot to the Spindle (N.)
just beneath the Cotter hole (R.) which passes through the said Spindle. Beneath
this Ring (S) and sliding tightly on the spindle is an iron or steel Cap (T.) see
detail Drawing Fig. 5. which shews the plan, front and side view.) The lower
part of this Cap is disc shaped having two bolt-holes and cotter hole (U) at right

page_text: angles to the bolt-holes-passing horizontally through the Disc. A corresponding
ootter hole passes through the spindle to carry the Cotter (V) which holds the
Cap (T.) closely up to the Ring (S). The Cotter (W) passing through the cotter
hole (R.) gives extra stability to the Ring (S.).
Placed immediately below the Cap (T.) is a series of thin discs of wood or other
suitable material (X. X. X. X.) The discs are in halves and have a hole in the centre
to allow the Spindle (N.) to pass through-also Bolt holes as shewn.. Beneath the
Discs (X. X. X. X) and sliding tightly on the Spindle (N.) is a lower Disc (Y.) of
iron or steel and having bolt holes exactly corresponding to those in the Discs (X.X.)
and the Cap (T.) the part of the holes to carry the bolt heads being recessed
upwards so as to allow the heads of the Bolts to rise clear of the lower face of the
Disc (Y.) on which the Cams (M. M.) act. The Screw Bolts (Z. Z.) pass upwards
through the lower Disc (Y) the Discs (X. X) and the Cap (T.) the whole being
held tightly secured by the Screw Nuts on the upper face. By this arrangement of
the Lifters compensation in the amount of fall of the Spindles by reason of the wear
on the Stamps Shoes can be made-also the lift can be varied by using more or
less of the Discs (X. X.).
The "Cover" or Box in which the Stamps Heads (O. 0) and the Stamps
Shoes (P. P.) act, is formed on the front of each Battery by two cast or wrought
iron or steel plates. The upper one (a. a.) Figs. 1. and 2.) being a plain oblong plate
and bolted through the side pieces (G. G.) a similar plate (b. b.) is fixed to form the
back of the "Cover" and held in position by the same screw bolts.
The lower Front plate (c. c.) has an oblong opening along the centre of the same
in which the Grate Frame (d. d.) fits closely-the screw studs having Screw and nut
on the outer ends being screwed into the plate at e. e. to carry the Grate Bar (f. ƒ.)
which Bar has a loop at each end through which the Studs (e. e.) pass. The screw
nuts on the Studs thus holding the Grate Frame (d. d.) in position-the Grate
Bar (f) impinging on the projecting convex ends of the same.
The
Placed on the inner side of the lower Front Plate (c. c.) is a second plate (g. g.) of
similar size, but the opening for the Grate Frame is of the same dimensions as the
inside measurements of the Grate Frame, thus forming a rebate for the same.
inner plate (g. g.) is bolted to the outer one (c. c.) the bolt holes being so arranged as
to render the inner plate reversible when desired-the outer plate being bolted or fixed
to the side pieces (G. G.).
A pass plate (h. h.) similar in all respects to the lower front plate (c. c.) is affixed
to the side pieces (G. G.) to form the back of the "Cover". and at the same level as
the Front Plate (c. c.).
Within the "Cover" of each Battery and of size suitable for the number of Stamps
Heads in the same, is a Foundation Plate (j.) of cast iron or other suitable material
bedded flat and secured by lugs and screw bolts to the Bed (A. A.) This plate has
a rib raised around the upper edges to contain within the ribs and c
on the upper face
as many Sole Plates (k. k.) of iron or steel as there are Stamps Heads and in
such position that the Sole Plates shall be on the same vertical centres as the
Stamps Heads.
The Stamps Grate (l. 1.) is held in position in the rebate formed around the opening
in the plate (g. g.) by the Grate Frame (d. d.).
Having now described the nature of my Invention-I claim as novel-the.construc-
tion and arrangement of the Bearers (J. J.) and the Bushes (K..K.) and the Bush
Caps (L. L.) singly and collectively.
Also the construction and arrangement of the" Cover," with the upper Front
Plate (a. a.) the Lower Front Plate (c. c) the Upper Back 'Plate (b. b.) and the pass
plate (h. h.) also the arrangement of the Grate Frame (d. d.) the Grate Bar (f.f)
and the Studs (e. e) collectively with the second plate (g. g.).
Also the construction and arrangement of the Foundation
pieces (F. F.) the Side Pieces (G. G) and the Stands.or
collectively and as a whole.
