PROVISIONAL SPECIFICATION.
An Improved Process for the Cleaning of Glass Bottles.
JAMES ARTHUR THOMSON, 85, Alexandra Parade, Dennistoun, Glasgow, Silver-
smith, do hereby declare the nature of this invention to be as follows:-
Two gas-heated annealing "muffels "
or ovens, rectangular in shape, and
constructed each with two doors, one at either end. These ovens are placed
facing each other and standing about six feet apart, the connecting platform
between being fitted with rollers to assist the carriage of the bottles between the
ovens. A tray or basket is required to hold the bottles, the construction of
which is as follows:-
Two rails or frames, rectangular in shape and about three feet six inches
long by two feet wide, are formed of cycle tubes, the one supported directly above
the other by tube uprights, six in number, a few inches in height according to
the height of the bottle. The bottom is formed of tubes about one inch apart,
their diameter being half that of the rail tubes.
One of these trays or baskets, being filled with the bottles, is placed in oven
No. 1 which is kept at a uniform temperature of 200° F., ten minutes being
allowed for this operation. The glass being now tempered, the bottles are trans-
ferred to oven No. 2, the temperature of which is sufficient to bring the glass
to a red heat. Ten minutes will be sufficient to destroy the matter in the bottles,
after which the tray is withdrawn and set aside to cool. The ovens are then
recharged after each withdrawal. When cold, the tray and contents are removed
to the wash-tub, a vessel of convenient size, filled with water heated by steam
or by other means. A pump being affixed to the side of the vessel with a
flexible tube attached, small enough to enter the neck of the bottle, the force

be worked either by foot or by power. As each bottle is washed it is placed in
a rack bottom up, and is now ready for re-filling, being chemically clean.

JAMES ARTHUR THOMSON, 85, Alexandra Parade, Dennistoun, Glasgow, Silver-
smith, 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 an 1
by the following statement:-
This process consists in applying fire to destroy all foreign matter adhering
to glass bottles, and is carried out as follows;-
-

page_text: Two gas-heated, annealing muffels or ovens, rectangular in shape, and con-
structed each with two doors one at either end. These ovens are placed facing
each other and stand about six feet apart, the connecting platform between
being fitted with rollers to assist the carriage of the bottles between the ovens.
A tray or basket, is required to hold the bottles, the construction of which is
as follows. Two rails or frames, rectangular in shape, are formed of cycle tube,
the one rail being supported above the other by tube uprights, a few inches in
height, according to the height of the bottles. The bottom also is formed of
cycle tubes, placed at a convenient distance apart, to suit the size of the bottles,
their diameter being about half that of the rail tubes.
The accompanying drawing shews the ovens A and B, Fig. 1, with the door-
ways C and D, E and F. The doors are not shewn, as they can be made to open
in whichever way is found to be the most convenient. H, the connecting plat-
form is shewn with the rollers J J J fitted in. Fig. 2 is the basket or tray for
holding the bottles when placed in the ovens. Fig. 3 is a board, rectangular,
or of other suitable shape, made with holes, K K K, into which the bottles are
inserted while being washed. Fig. 4 shews the wash-tub N, containing rectan-
gular or other suitably shaped frame, which is fitted with nozzles or pipes M M M,
equal in number to the number of holes KK K, Fig. 3.
The tray,
Fig. 2, being filled with bottles, is placed in the tempering oven A,
which is kept at a uniform temperature of 200° F., ten minutes
being sufficient for this operation. The glass being now tempered, the basket
and its contents are transferred to the other oven B, their passage being assisted
by the rollers J J J. The temperature of the oven B being sufficient to bring
the bottles to a red heat, a few minutes is sufficient to destroy all the foreign
matter adhering to the bottles, after which the tray Fig. 2 and contents are
withdrawn and set aside to cool. The ovens A and B are recharged after each
withdrawal. When cold, the tray Fig. and contents are removed to the wash-
tub, N (Fig. 4). The board Fig. 3 being filled with bottles, neck downward,
is placed over the nozzles, through which hot or cold water is forced by pumping
or other suitable means. After the bottles are thoroughly washed, they are set
aside to drain, and when drained are ready for refilling, as they are now chemi-
cally clean.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is
1. A process for the cleansing of glass bottles, wherein they are first tempered
by fire, in a suitably constructed oven, thereafter they are brought to a red heat,
when all the foreign matter adhering to the bottles is destroyed.
2. Processes such as referred to in the First Claim, operating as herein des-
cribed, with reference to the accompanying drawing.
