Improvements in Envelope Moisteners.
I, JOHN GEORGE EVERSMAN of Market Street, Denver, Colorado, U.S.A.,.
Merchant, 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 :-
The envelope moistener of this invention has for object to render unnecessary
the unhealthful practice of moistening the gummed surface of envelope flaps with
the tongue and to provide for this purpose a simple, durable and efficient device
which in the accompanying drawing is shewn in Fig. 1 in perspective view, and in
Fig. 2 in cross section.
5 is a shallow box or a tray containing an absorbent pad 6 of felt or other
suitable material. Attached to this tray and projecting a short distance above the
body thereof is a flap opener 7 of wire or other suitable material. At its junction-
say by soldering-with the tray, it is bent round approximately to a right angle,.
then extending in a curve to terminate at the opposite corner in a free or unsupported.
extremity so as to allow it to yield when pressed.
To use the device, the envelope is taken in the hand with the flap side down,.
and drawn across the wire 7 which catches and opens the flap so that the gummed
surface thereof will be pressed to engage the pad 6 when the flap leaves the wire 7..
The absorbent pad which is kept moistened with sufficient water for the purpose,.
applies sufficient moisture for sealing purposes, to the gummed surface of the flap.
As the envelope is drawn across the wire 7 the latter is subjected to sufficient
pressure to cause it to move downward, whereby the flap as it leaves the yielding
wire, passes immediately to contact with the upper surface of the pad, and as the
Hlap is drawn across the pad the gum on the flap is sufficiently moistened for all!
practical purposes as before stated.
Having now particularly described and ascertained the nature of my said inven-.
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An envelope moistener comprising a shallow box or tray containing an
absorbent pad, and a flap opener composed of a piece of wire attached to the tray
and projecting a short distance above the body thereof, substantially as described.
and shewn.
2. An envelope moisteuer comprising a shallow box or tray filled with some
suitable absorbent material, and a flap opener consisting of a piece of wire fastened.
to one corner of the tray, extending upward a short distance above the body of the
tray to a bend and thence lengthwise of the tray to the opposite corner where it
terminates in a free or unsupported extremity, substantially as described and.
shewn.

Improved Corkscrew.
I, OTTO HEINRICH CHRISTIAN VOIGT, of No. 11 Fleischhauerstrasse, Lubeck,
in the German Empire, Merchant, 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:-
The object of the present application for Letters Patent consists in a safety
corkscrew by the use of which any damage or breakage of the lip of the bottle is
avoided; moreover the adjustment of the apparatus is extremely simple, practical
and efficient.
Referring to the accompanying drawing in which the apparatus is shown in three
views:
Figure 1 shows the apparatus in side view.
Figure 2 shows a vertical section through the lower edge.
Figure 3 section through the corkscrew haudle.
Figure 4 shows the ring provided with plate in its special shape.
The corkscrew holder a is provided at its lower edge with a round groove
running around it, in which a suitable indiarubber ring b is inserted. This
indiarubber ring b is provided with an indiarubber plate which covers the under
surface of the cork drawing apparatus completely so that any contact of the
neck of the bottle with the apparatus during the use of the same is avoided.
Consequently a breakage of the glass and the risk of injury to the hands becomes
impossible. The corkscrew handle c is revoluble by means of the screw spindle
attached to it and passing through the threaded matrix in the upper part of the
corkscrew frame or holder a. The handle c is held firmly by means of the following
arrangement
A screw d sharp at its end and hardened, is arranged to screw into one end of the
handle in the mauner shewn in the drawing and on being screwed up against the
screw spindle aforesaid, the screw d holds the spindle at any point because dis
sharp and hardened at the point. When it is desired to insert the corkscrew in a
cork the handle is firmly fixed by screwing up the screw d. As soon as the
corkscrew is forced sufficiently deeply into the cork by turning the handle c, the
set screw d is unscrewed whereby the handle is released. If this be now turned to
the right around the corkscrew spindle, a steady raising of the cork is effected
without the need of drawing the cork.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A safety corkscrew with adjustable handle and an indiarubber ring and plate
fitted to the lower edge of the frame attached without adhesive material, which
prevents when in use any contact between the said frame with the bottle neck
whereby the breakage of the latter and damage to the hands is avoided.
2. The improved safety corkscrew apparatus substantially as described and
illustrated in the accompanying drawing.

Improvements in or relating to Centrifugal Machines for Examining
and Testing Milk, Sediments of Urine, and other Fluid Substances.
I FRANZ HUGERSHOFF of 28 Alberst Strasse Leipzig in the German Empire,
Manufacturer do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:—
The object of my invention is to effect improvements in hand driven centri-
fugal machines used for examining and testing milk, the sediments of urine, and
other fluids.
And in order that my said invention may be particularly described and ascer-
tained reference is hereby made to the accompanying drawing which illustrates a
centrifugal machine constructed according to my invention.
The machine consists of an adjustable cramp in which a spindle w is suitably
mounted, the spindle carrying the usual tray or dish at its upper end. The
spindle w is provided with a flanged drum a loosely mounted thereon and normally
held in the position shown by the drawing by the spring b. The under side of the
drum a is formed with a clutch or tooth a¹ arranged to drive the spindle by con-
tact with the pin a², which is integral with the spindle.
It will therefore be seen that on a band or cord being passed round the drum a
and motion imparted thereto with a slight downward tendency, the drum is driven
downward against the power of the spring and the tooth a¹ becomes engaged with
the pin a whereby the spindle is rotated. By means of this arrangement a
reciprocating action of the drum imparted by a length of cord or a band may, by
alternate upward and downward pressures, be caused to convey a continuous rotary
motion to the spindle and pan or dish.
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
1 claim is:
'
1. The improved centrifugal machine substantially as set forth.
2. In centrifugal machines for testing, examining, separating, or investigating
purposes, the application and use of driving drum or pulley loosely mounted on
the spindle and arranged to engage with a pin fixed to the spindle arranged and
operating substantially as herein before described and illustrated by the drawing.
3. The combination with the spindle carrying the pan, dish or tray, of a flanged
drum, or pulley a loosely mounted on the spindle; a clutch or tooth a¹ integral
with such drum or pulley; a pin or stud a² integral with the spindle and a
spring b, severally operating substantially as and for the purposes herein described
and shown by the drawing.

to be reproduced through a screen, as used by photo etchers for the purpose. The
negative thus obtained is used to print or transfer the subject upon the metal
plate, by any of the known methods.
The plate may be of any metal suitable for etching, and the plate is etched in
the ordinary manner. The plate thus treated is to be used as the picture, and to
obtain the desired effects, I carefully rub coloured chalks, pigments, or any
suitable tints, or colours, into the etched plate. I find colours in powders or
pastels preferable, the tints blending easily.
Having now particularly described and ascertained the nature of my said

page_text: invention and in what manner the same is to be performed I declare that what

Improvements in the Manufacture or Preparation of Adenin.
I, JAMES YATE JOHNSON, of 47, Lincoln's Inn Fields, in the County of London,
Gentleman, do hereby declare the nature of this invention (which has been com-
municated to me from abroad by C. F. Boehringer & Soehne, of Waldhof, near
Mannheim, in the Empire of Germany) to be as follows:-
Adenin was discovered by Kossel, and by him converted into hypoxanthine. .In
spite of the subsequent protracted experiments of Krüger (Zeitschrift für physiologische
Chemie, 18,423) the structure of the base is by no means clear, and there is lacking
experimental proof of the direct relation of the substance to uric acid.
Professor E. Fischer of the firm of my foreign correspondents has now succeeded
in adducing this proof by effecting the synthesis of adenin from uric acid.
According to this new investigation adenin must be represented by the formula of
a 6-aminopurine,
N=C-NH,
HC
C-NH
CH
-
Its artificial production is brought about by reducing 6-amino-2 : 8-dichloro-
purine, obtained from 2: 6: 8-trichloropurine.
It is convenient to proceed as follows:-Powdered 6-amino-2: 8-dichloropurine is
added to 10 times its weight of hydriodic acid of 1.96 specific gravity the liquid,
treated with the sufficient quantity of powdered phosphonium iodide and agitated at
ordinary temperature for several hours.
Without becoming completely dissolved, the chlorocompound is converted into
adenin, the hydriodide of which separates in slightly coloured crystals. The liquid
is finally boiled, until a clear solution is obtained.
The adenin hydriodide which separates once more on cooling, is filtered off, and in
concentrated aqueous solution decomposed with ammonia.
Obtained in this way the base is colourless and is pure after recrystallisation from
hot water. It possesses all the properties of the natural base (Kossel, Zeitschrift für
physiologische Chemie, 12,252).
A further quantity of the base may be obtained by evaporating the hydriodic acid
mother liquor, and treating the residue with ammonia.
Dated this 7th day of October 1897.

Improvements in Milk Cans.
Year: 1897

page_text: Date of Application, 15th Jan., 1897-Accepted, 20th Mar., 1897
Improvements in Milk Cans.
I, WALTER SALE GUILFORD of 23, Pevensey Road, Eastbourne, Sussex,
Surveyor and Estate Agent, 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 :-
This invention relates to improvements in milk cans and has for its object to
provide a can which will keep the milk sweet longer than the ordinary
arrangement.
In carrying out my invention I make the milk can of ordinary shape and of
various sizes according to the requirements, but instead of the bottom of the can
having sharp corners at the inside it is rounded so that all parts can be easily
reached for cleaning purposes. The top of the can I propose to make of
tapering or truncated conical form having a rim or flange at the bottom which
fits closely into the upper end of the can. The top of the cover which is flat is
provided with a ventilator formed by perforating the metal, thus allowing a
current of air to pass continuously through the can assisting in keeping the milk
from turning sour. I prefer to make the can from metal with an enamelled
lining.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings, in which Fig. 1 is a side elevation of my
improved can, and Fig. 2 is a vertical section.
The body A of the can is of circular shape in plan, and the bottom a is
rounded at the edges, as shown clearly in Fig. 2, thus preventing the formation
of sharp corners and allowing all parts of the can to be easily reached for
cleaning purposes. The cover B of the can is of tapering or conical form, and
is provided with the flange or rim b extending into the top of the can. The
top of the cover is perforated at 62 so as to form a ventilator. This ventilator
not only assists in keeping the milk sweet, but also when the can is empty
ensures its keeping dry and clean, owing to the air constantly passing through
it. A strong handle is furnished sufficiently deep to clear the top of the cover.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.―
(1.) A new or improved milk can formed with a rounded bottom and a cover
fitting in the top of the can, furnished with a ventilator, substantially as
described and for the purposes specified.
(2.) A new or improved milk can formed with a rounded bottom and provided
with a cover of conical shape fitting into the top of the can, and perforated at
its upper end to form a ventilator, substantially as and for the purposes specified.
(3.) The improved ventilated milk can constructed as described and shown
in the accompanying drawings and for the purposes specified.

Improvements in Valves and Fittings for Lavatory and other
Purposes.
I, MOSES JAMES ADAMS, Engineer, Park Lane Sanitary Works, Leeds, do
hereby declare the nature of this invention to be as follows:-
My improvement consists in the use of a vertical tube which shall be so
arranged within a socket that it may slide up or down or telescope and when this
is fixed in a lavatory basin or other vessel and drawn out to its full height water
will remain in the vessel at that level but when pushed down within its socket
the water will flow away through it to the lower level and I arrange my water
supply where desired to act without taps using a tipping bucket to fill basin or
using a vessel and displacer for the same purpose.

Improvements in Wire Spring Mattresses.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, as communicated to me by Emile
Semal, Manufacturer, of Nivelles, Belgium, to be particularly described and ascer-
tained in and by the following statement:
This invention relates to a wire spring mattress furnished with an adjustable
head piece which can be raised or elevated as desired.
In the accompanying drawings Fig. 1 represents the mattress attached to the
two posts of a bedstead forming thus a complete bedstead and mattress, Fig. 2
shows the mattress alone, which may also be secured to a wooden frame. The
mattress is composed of a trellis work of steel wire of coarse mesh, this trellis
work is fixed to the frame (or wooden body) of the mattress by means of steel
wires.
ན
The head A of the mattress is moveable and hinged at the point marked B
in Fig. 2; the mobility of this part of the mattress constitutes the raising or
elevating head piece.
This moveable part is supported by means of flat pieces of iron E pivotted one
or loosely jointed one on each side of the mattress frames and perforated with
several holes and engaging spurs or pins D fixed on the main side members of
the mattress thus enabling the desired inclination and rigidity to be secured.
At the point F the trellis work is permanently turned up for fixing to the
bottom cross piece of the mattress frame; to prevent the sleeper from slipping.
down in the bed.
This mattress may also be mounted on a wooden frame as shown in Fig. 3.
The advantages of this form of mattress are:-
1. The dispensing with a head piece by reason of the use of the raising or
elevating head A.
2. The steel wire trellis work readily yields to the shape of the body.
3. There is perfect elasticity in two thirds of the mattress at the parts where
the greatest strain is felt.
Health, cleanliness, small space, easy setting up and taking down, and economy
in cost and highly suitable for private houses, boarding houses and charitable
institutions.
my
Having now particularly described and ascertained the nature of said
invention, and in what manner the same is be performed, I declare that what I
claim is:
A wire spring mattress attached to a frame and having an adjustable head piece
substantially as described with reference to the accompanying drawings.
