COMPLETE SPECIFICATION.
Improvements in and relating to Appliances for Affixing Stamps
and Labels.
We, ARCHIBALD WELSH, and WILLIAM MUIR, both of the Firm of
Archibald Welsh and Company, Brassfounders, Carrick Brass Works, in the
Town and County of Ayr do hereby declare the nature of our invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement in writing, that is to say :-
This invention relates to an improved construction or arrangement and combina
tion of the parts of a hand operated appliance or machine applicable for affixing
stainps on to envelopes and labels on to other articles.
And in order that this invention and the manner of performing or carrying the
same into practice may be properly understood there is hereunto appended an
explanatory drawing in which Figure 1 represents a front elevation, and Figure 2
a view at right angles thereto of an appliance or machine as constructed in
accordance with these improvements and applicable for affixing postage stamps on
to envelopes and the like.
This appliance consists of a vertical spindle A depressed by hand, and which is
returned to its normal position by the recoil action of a helical spring A' enclosed
within an annular tube or sleeve B. The lower end of this sleeve B bears over
the one end of projecting bracket plate B' carrying at its other end a liquid
reservoir b. This plate B' is carried by a kneed bracket B2 having a vertical
stein B3 supported within a hollow standard C. This standard is preferably made
in two parts hinged together at C', so that when the pinching screw C2 which
locks the stem B³ is slackened and the stem B³ raised above level of hinge, the
upper part of standard C can be swivelled on its hinge C¹ and thus allow of spindle A
being tilted over or taken out for the insertion of stamps within its receptacle
hereinafter described. The lower end of the spindle A is formed with a solid
plunger or plate A2 and a casing or hollow receptacle a is mounted round this
plunger A2 to contain the stamps. This casing is formed with a slotted tubular
stem a mounted loosely round a narrow part of the spindle A and having a helical
spring a round the spindle A at this part.
Toggle link fittings are used to operate the damping pads consisting of links d
having upper slotted ends d¹ working within pin and cheek guides at B₁ on
bracket B2. The lower end of the links d are soldered or secured to chambers or
receptacles d' while links d³ connect the links d by pin joints to crosshead arms or
projections A³ formed on the spindle A. Damping pads preferably consisting of
brush hairs D are secured within tubular sockets and soldered or secured through
a slot in the chambers d². A tube D' projects out from one of the chambers d²,
and an india rubber or flexible tube D2 is secured between this and the lower end
of the liquid reservoir vessel b. The liquid reservoir consists of lower and upper
metal caps & having a glass cylinder or vessel b fitted between these to form a
"sight feed reservoir. A plug is fitted through the top cap for filling the
liquid into reservoir and a hollow metal stem 6 is fitted through the centre of
vessel b. A hand operated screw spindle 6 is fitted within the hollow stem b', and
as the lower end of this spindle is raised above or screwed down below an orifice
at 6 in the stem the supply of liquid through stem and passage to the
flexible tube and damping pad is continued or shut off or its quantity regulated.
G

page_text: By this arrangement the water will flow from the reservoir 6 through the pipe
connections to one of the chambers d and supply the brush pad D. This in turn
will communicate part of its supply to the other brush D which normally presses
against it.
When the stamping handle A is depressed the brush pads D will
simultaneously be operated to move outwards and in so moving will with their
lower ends damp the surfaces on which the stamps are to be affixed. The stamp
receptacle a will follow down and bear over the damped surface, while the plunger
end A² of spindle will then exercise the necessary pressure to affix stamp on to
damped surface. the whole operations being done by one action of the handle A.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
First. The arrangement in combination of the parts forming an appliance or
machine to damp and affix stamps, labels and the like on to surfaces, by one action
substantially as herein described in reference to and shown in the accompanying
drawings.
Second. In machines for affixing stamps, labels and the like the arrangement of
toggle link appliances for working in combination with hand operated spindle,
substantially as herein described in reference to and shown in the accompanying
drawings.
