No. 13716.—10th June, 1901.—LAMBTON LE BRETON
MOUNT, Auckland, New Zealand, Glass-manufacturer
(assignee of Jonathan Haley and Harry H. Bridgwater, both
residing at Akron, Ohio, United States of America). An
apparatus for forming hollow glass articles.

Extract from Specification.—This invention relates to im-
provements in apparatus for forming hollow glass articles,
such, for instance, as bottles and jars; and the invention
relates more especially to the formation of hollow glass
articles by first pressing or moulding a quantity of glass
into a hollow form and then expanding the blank by
blowing into the latter. Heretofore one great obstacle en-
countered in an effort to manufacture a perfect jar or
bottle was the imperfections appearing upon the neck of the
bottle or jar, and resulting from the lateral sliding or
removal of the jar or bottle from one to another of the
moulds required or employed in the formation of the said
article. The imperfections referred to consisted in crizzles,
formed mainly on the neck of the article, but formed also
upon other portions of the article. The primary object of
this present invention is to avoid the said crizzles or im-
perfections in the hollow glass article being formed, by
requiring the blank to be moved vertically only, and hence
avoiding any lateral movement of the blank. Other objects
of this invention are to simplify the construction of ap-
paratus of the character indicated to render the same more
convenient and reliable in its operation, and to reduce the
cost of hollow glassware adapted to be formed by the said
apparatus.

[NOTE.—The number and length of the claims in this case pre-
clude them from being printed, and the foregoing extract from the
descriptive part of the specification is inserted instead.]

An improved apparatus for ventilating milk and cream during
separation by cream-separators.

Claims.—(1.) An apparatus for ventilating milk and cream
during their separation by means of a cream-separator, which
apparatus comprises a cream-pipe connected to the cream-
separator, a system of tubing connected to said cream-pipe
and adapted to communicate with a source of fresh air,
means for preventing foreign matter from passing with the
air through said system, and means for preventing the ad-
mission of air from the workroom into the cream-pipe, in com-
bination, substantially as described. (2.) An apparatus for
ventilating milk and cream during their separation by means
of a cream-separator, which apparatus comprises a cream-
pipe connected to the cream-separator, means for conveying
a constant supply of pure air to said cream-pipe, and an
automatic counterweighted valve adapted to close the dis-
charge end of said cream-pipe, in combination, substantially
as and for the purpose set forth. (3.) An apparatus for venti-
lating milk and cream during their separation by means of
a cream-separator, which apparatus comprises a cream-pipe
connected to the cream-separator, a system of tubing con-
nected to said cream-pipe and adapted to communicate with
a source of fresh air, means for preventing foreign matter
from passing with the air through said system, and an
automatic counterweighted valve adapted to close the
discharge end of said cream-pipe, in combination, sub-
stantially as and for the purpose set forth. (4.) An appa-
ratus for ventilating milk and cream during their separa-
tion by means of a cream-separator, which apparatus com-
prises a cream-pipe connected to the cream-separator, and
adapted to discharge into an airtight cream-receiver, a lid
adapted to make said receiver airtight, and means for con-
veying pure air to said receiver, in combination, substan-
tially as and for the purpose set forth. (5.) An apparatus
for ventilating milk and cream during their separation by
means of a cream-separator, which apparatus comprises a
cream-pipe connected to the cream-separator, a receiver, a
lid adapted to make said receiver airtight, and to which the
cream-pipe is connected, a pipe system also connected to
said lid, and adapted to convey pure air to the separator
system, in combination, substantially as and for the purpose
set forth.

closed vessels.

Claims.—(1.) An apparatus for enabling milk and cream
to be stored or carried for a long time in closed vessels, which
permits fresh air to be conducted into such vessels, and used-
up air to be simultaneously expelled therefrom, substantially
as described. (2.) In an apparatus for ventilating milk and
cream in closed vessels, the combination of a system of
piping adapted to communicate with a source of fresh air,
a lid adapted to make the vessel airtight, an exit-pipe
mounted in said lid, and a ventilating-fan in communica-
tion with said exit-pipe, substantially as described. (3.) In
an apparatus for ventilating milk and cream in closed vessels,
the combination of a system of piping adapted to communi-
cate with a source of fresh air, and a closed vessel, a lid
adapted to make such vessel airtight, a second system of
piping connected to the lid of said vessel, and means for
withdrawing the used-up air from said vessel, substantially
as described.
