the like.
I, JOHN CARLOS CALASTREMÉ, of 27 Burghley Road, Highgate Road, in
the County of Middlesex, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
My invention consists of a method of fixing sight feed glasses, gauge glasses and
other like glasses, whereby all ordinary glands are dispensed with.
1 place the sight glass, gauge glass or other like glass, at its lower end, on a
washer of suitable material, and at the upper end I place a washer of Lor other
suitable section to take the top of the glass and fit the sides of a small upper
chamber. The steam pressure in such upper chamber is sufficient to hold the glass
firmly and tightly in position by virtue of the difference in areas on which the
pressure acts, or, as an alternative scheme, I use a small piston head with packing
or ring to prevent escape of steam, which bears on the upper end of the glass and
receives the pressure of steam and thereby forces the glass tightly down, thus
dispensing with all glands, springs or other complicated and troublesome appliances.
I also may use a thimble tube, the upper part of which fits the interior of the upper
chamber and is prevented turning therein, and is provided with an inwardly
projecting flange to bear on the top of the tube, whilst its lower part projects
beyond the bottom of the upper chamber, where it is screw threaded on its exterior
and is fitted with a nut, which enables still further pressure to be applied in
tightening up the glass at both top and bottom.

1, JOHN CARLOS CALASTREME of 27 Burghley Road, Highgate Road, in
the County of Middlesex, Mechanical 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, reference being had to
the accompanying drawings and to the figures and letters marked thereon :-
My invention consists of a method of fixing sight feed glasses, gauge glasses, and
other like glasses for steam generators and the like whereby all ordinary glands are
dispensed with.
In the accompanying drawings Figure 1 is a sectional elevation of a water gauge
showing one method of carrying my invention into effect and Figures 2 and 3 are
sectional elevations of the upper parts of water gauges showing modifications.
According to the arrangement represented at Figure 1, I place the gauge glass a
at its lower end on a washer of suitable material placed in a recess in the fitting c
and at its upper end I place a compressible washer d of suitable section to take the
top of the glass and fit the sides of a small upper chamber e in the fitting f. I also

page_text: place on the top of such washer da rigid washer d¹ of brass or other suitable
material.
The steam pressure in such upper chamber is sufficient to hold the glass a
firmly and tightly in position by virtue of the difference in areas on which the
pressure acts.
As an alternative scheme I use as represented at Figure 2 a small piston head d
with packing or ring d³ to prevent escape of steam, which bears on a compressible
washer d at the upper end of the glass a and receives the pressure of steam and
thereby forces the glass a tightly down on to the packing ring at the bottom end
thereof thus dispensing with all glands, or other complicated and troublesome
appliances.
I may also use as represented at Figure 3 a thimble tube the upper part of
which closely fits the interior of the upper chamber and is prevented turning
therein by means of a feather and key way as shown or by other suitable means.
This thimble tube d is provided with an inwardly projecting flange to bear on a
washer of flexible material placed on the top of the tube a whilst its lower part
projects beyond the bottom of the upper chamber e where it is screw threaded on
its exterior and is fitted with a nut which enables still further pressure to be
applied in tightening up the glass a at both top and bottom.
I have only represented my invention as applied to a gauge glass but it will be
well understood that it is equally applicable and in like manner to sight feed glasses
and other glasses for steam generators and the like.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performned I declare that what I
claim is:-
The improved means for securing in place sight feed glasses, gauge glasses and
other like glasses for steam generators and the like substantially as herein shown
and described.

PROVISIONAL DI MOITIVATION
Improvements in Sight Feed Lubricators.
I, JOHN CARLOS CALASTREME of 27 Burghley Road, Highgate Road in the
County of Middlesex Mechanical Engineer do hereby declare the nature of the
said invention to be as follows :-
The invention relates to sight feed lubricators and the improvements consist of a
modified and improved construction combination and simplified arrangement of the
parts constituting the apparatus.
The body or oil chamber of the apparatus is surmounted with a tubular T piece,
or such tubular piece may be of V form to accommodate delivery pipe and
couplings. Into this T or V shaped piece steam is admitted, and part of this steam
is conducted by the inlet passage of the Tor V shaped piece into a vertical hole or
passage cast in the wall of the oil chamber and leading to the bottom of said
chamber, which passage is so made as to extend partly around the oil chamber in a
form concentric with said chamber, or it may form a complete outer shell if required
to provide for a more complete condensation; or as an alternative scheme I may
form the cylindrical part or oil vessel with a false bottom whereby I again increase
the condensing surface or two or more false bottoms plates or divisions may be
employed.
The steam inlet passage is also in connection by means of a short channel, with
the top of the sight feed chamber or glass through which the lubricant passes after
delivery from the nipple at the top of the oil chamber and from which it rises
into an outlet steam channel and thence it is driven into the part requiring to
be oiled.
It is usual to combine the lubricator and delivery regulating tap, but for the
purpose of economy in repairs and renewals, I prefer that the regulating tap be
separately attached and dealt with.
The method of fixing the sight glass whereby all ordinary glands are dispensed
with is as follows :-
-
"
1 place the sight glass at its lower end on a washer of suitable material and at
the upper end I place a washer of L or other suitable section to take the top of the
sight glass and fit the sides of a small upper chamber. The steam pressure in such
upper chamber is sufficient to hold the glass firmly and tightly in position by virtue
of the difference in areas on which the pressure acts, or as an alternative scheme, I
use a small piston head with packing or ring, to prevent escape of steam, which
bears on the upper end of the glass and receives the pressure of steam, and thereby
forces the glass tightly down thus dispensing with all glands, springs or other com-
plicated and troublesome appliances. I also may use a thimble tube the upper part
of which fits the interior of the upper chamber and is prevented turning therein
and is provided with an inwardly projecting flange to bear on the top of the sight
tube whilst its lower part projects beyond the bottom of the upper chamber where
it is screw threaded on its exterior and is fitted with a nut which enables still
further pressure to be applied in tightening up the sight glass at both top and
bottom.
The oil chamber is supplied with oil through an opening which is closed by a
screw plug or valve, it is also provided with a tap or cock through which the
contents can be drawn off; and the oil passage from the oil chamber is fitted with a
regulating valve to regulate the quantity of oil delivered to the nipple.

page_text: The oil chamber is also provided with a screwed projection by which the
labricator can be readily attached to the engine or other apparatus.

COMPLETE SPECIFICATION.
Improvements in Sight Feed Lubricators.
I, JOHN CARLOS CALASTREME of 27 Burghley Road, Highgate Road in the
County of Middlesex, Mechanical 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 reference being had
to the accompanying drawings and to the figures and letters marked thereon:-
The invention relates to sight feed lubricators and the improvements consist of a
modified and improved construction, combination and simplified arrangement of the
parts constituting the apparatus.
In the accompanying drawings Figures 1 and 2 are vertical sections of my
improved sight feed lubricator drawn at right angles to each other, Figure 3 is a
plan partly in section and Figure 4 is a horizontal section drawn on the line 1-1.
of Figure 2.
Figure 5 is a plan showing a V formed tubular piece for connection with the
steam and delivery pipes.
Figure 6 is a cross section of a lubricator showing a completely cylindrical
condensation chamber.
Figure 7 is a vertical section showing a false bottom in the lubricator and
Figure 8 is a vertical section showing a modification..
In all the figures like parts are indicated by similar letters of reference.
b
The body or oil chamber a of the apparatus is surmounted with a tubular
T-piece as shown at Figure 3 or such tubular piece b may be of V form as shown
at Figure 5 to accommodate steam and delivery pipes and couplings.
Into this T or V shaped piece steam is admitted by the inlet passage b¹ and
part of this steam is conducted by such inlet passage through a short passage.c
into a vertical hole or passage d in the wall of the oil chamber a and leading to
the bottom of said chamber, which passage.d is so made as to extend partly
around the oil chamber a in a form concentric with said chamber as shown at
Figures 1, 2, 4, 7 or it may form a complete outer shell, as shown at Figure 6, if
required to provide for a more complete condensation; or as an alternative scheme
I may form the cylindrical part or oil vessel a as shown at Figure 7 with a false
bottom, a whereby I again increase the condensing surface, or two or more false
bottoms may be employed..
The steam inlet passage b¹ is also in connection by means of a short channel e
with a chamber at the top of the sight feed chamber or glass g through which the
lubricant passes after delivery from the nipple at the top of the oil chamber a
and from which it rises into an outlet steam channel 62 and thence it is driven into
the part requiring to be oiled.
I also introduce a ball or mushroom valve i into the channel e connecting the
steam passage with the hole or passage.d or. I screw on an elevated chamber j
into which such passages extend, the connection from the steam passage being
fitted at its upper end with a small compensation, valve i.
The valves will thus open in the normal working of the lubricator to permit of
the passage of oil but in the event of a back pressure they will close.
It is usual to combine the lubricator and delivery regulating tap k but for the

page_text: purpose of economy in repairs and renewals I prefer that the regulating tap k
be separately constructed and attached to the lubricator by a screw connection.
The oil chamber a is supplied with oil through an opening a which is closed by
a screw plug or valve l, it is also provided with a tap or cock m through which the
contents can be drawn off and the oil passage from the oil chamber a is fitted with
a regulating valve n to regulate the quantity of oil delivered to the nipple h. The
oil chamber is also provided with a screwed projection as by which the lubricator
can be readily attached to the engine or other apparatus.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The improved sight feed lubricator constructed substantially as herein shown
and described.
2. An improved sight feed lubricator having a body containing an oil chamber,
an upper tubular piece for connection with the steam supply and delivery, an upper
chamber communicating by the sight feed glass with the top of the oil chamber, a
passage communicating between such upper chamber and the steam supply and
delivery passage, a vertical condensing passage communicating with the steam
passage and leading to the bottom of the oil chamber, and a nipple communicating
with the top of the oil chamber and opening into the sight glass substantially as
herein shown and described.
3. In sight feed lubricators an internal condensing passage communicating at its
upper end with the steam inlet and at its lower end with the bottom of the oil
chamber in combination or not with one or more false bottoms to said chamber
substantially as herein shown and described.
4. In sight feed lubricators, an internal condensing passage or chamber com-
municating at its upper end with the steam inlet and at its lower end with the
bottom of the oil chamber and extending either partially or completely around said
oil chamber substantially as herein shown and described.
