the removable releasing wards or lugs, for the purposes specified. (7.) In an apparatus as described in claim 1, mounting
the releasing wards or lugs rotatably on the key, for the purpose specified. (8.) In an apparatus as described in claim 1,
forming grooves in the keys, for the purposes specified. (9.) In
an apparatus as described in claim 1, the addition to the
mould-sides of a plate or series of thin bars projecting from
the inner lower face thereof, for the purpose specified.
(10.) In an apparatus as described in claim 1, superposed
metallic mould-sides having their adjacent edges overlapping
each other, for the purpose specified. (11.) In an apparatus
as described in claim 1, the formation of corresponding
recesses in the edges of the adjacent mould-sides, for the
purpose specified. (12.) In an apparatus as described in
claim 1, forming a hole through the mould-sides corresponding in shape to the releasing wards or lugs, for the purpose
specified. (13.) In an apparatus as described in claim 1,
forming the releasing wards or lugs in any of the shapes
shown in the drawings, for the purpose specified. (14.) In
an apparatus as described in claim 1, the formation of a
number of releasing wards or lugs on the key to enable a
plurality of moulds to be erected simultaneously.

No. 24223.—3rd April, 1908.—THOMPSON TYPE-MACHINE
COMPANY, of 130 Sherman Street, Chicago, Cook, Illinois,
United States of America, Manufacturers (the assignee of
John Smith Thompson, of 980 Belleplaine Avenue, Chicago
aforesaid, Printer). Type-casting machines.

Claims.—(1.) A machine for casting type, comprising a
sectional mould, a matrix-carrier, and a metal-pot supported
in a pivotally mounted yoke, means for adjusting the vertical position of the mould-sections, means for adjusting the
vertical position of the matrix-carrier, and means for adjusting the vertical position of the metal-pot. (2.) A machine
for casting type, comprising a mould, a matrix-carrier and a
metal-pot supported on opposite sides of said mould, means
for yieldingly pressing said matrix-carrier against said mould
to form a tight joint, and means for yieldingly pressing said
metal-pot against the opposite side of said mould until the
parts have reached the maximum expansion, in combination
with means for thereafter rigidly holding said pot against
said mould. (3.) A machine for casting type, comprising a
mould, a matrix-carrier and a metal-pot mounted on opposite
sides of said mould, a pivotally mounted yoke for supporting
the metal-pot, and means for adjusting the vertical and
horizontal position of the metal-pot in said yoke. (4.) A
type-mould, comprising a cap and base, an intermediate
body-piece controlling the body-wise and set-wise dimensions of the mould, two jet-blocks associated with said cap
and base for forming a jet on said type, a jet-piece working
between said jet-blocks, a vertically movable plate forming
one side of the mould and jet-cavities, and a pusher-plate
and associated parts to which said body-piece and jet-piece
are attached, and means for independently altering the
cross-sectional area of said mould and jet-cavities. (5.) A
type-mould, comprising type-forming and jet-forming parts,
means for introducing molten metal through the jet-forming
parts to the type-forming parts, and means for cooling the
jet parts, whereby the type-forming parts are maintained at

No. 24229.—8th April, 1908.—ARTHUR HJALMAR BORG-
STRÖM, of Hangö, Finland, Merchant. Improvements in the
continual manufacture of butter, and apparatus adapted
therefor.

Claims.—(1.) The method of manufacturing butter, consisting in causing the cream or milk, acted upon by the centrifugal force, to move along a rotating surface, finely fluted,
formed like a grater or made rough in any other manner,
so that a great friction is effected. (2.) An apparatus for
carrying out the method stated in claim 1, consisting of a
rotating vertical shaft provided with a plane or conical disc
which rotates with the said shaft, and the top side of which
is rendered very rough by the disc being finely fluted, perforated like a grater, or in any other manner ; and of suitable
means for supplying the cream continually to the disc, at
the centre of the same, in a quantity so adapted that the
cream by the action of the centrifugal force is spread on the
disc in a thin layer while moving outward towards the periphery of the same. (3.) A form of the apparatus stated in
claim 2, characterized by a number of discs 2, 2, .... being fixed
on the shaft one above the other and at some distance from
each other, and by stationary plane or conical plates 5, 5, ....
being mounted in the spaces between the said discs, which
plates are provided with suitable shields or the like, and
guide the liquid thrown outward from a superposed disc back
to the centre, and causes the same to pass downward to the
next subjacent disc 2 through an opening 8. (4.) In the
apparatus stated in claim 2 or 3, the arrangement of the
rough surface being provided on a separate plate mounted on
the disc. (5.) In the apparatus stated in claim 2 or 3, the
arrangement of the discs being mounted in a chamber shut
off from the atmospheric air and provided in the frame in
which the shaft is journalled, for the purpose that the low
temperature of the cooled cream may be maintained more
easily.
