PROVISIONAL SPECIFICATION.
Improvements in and relating to Hand Stamps.
I, JOHN GARDNER, of High Bank, Manchester Road, Altrincham in the
County of Chester, Type-writing Machine Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to hand stamps for endorsing and similar purposes, and
its object is to provide means whereby such stamps are prevented from forming
impressions which are heavier in one part than in another."
In carrying this invention into effect, the handle of the stamp is loosely or
movably connected to the plate carrying the printing surface, and is preferably
in contact with it at one point only. A convenient way of constructing a hand
stamp to embody these improvements is to form the handle with a rounded or
conical base adapted to bear upon the plate or a projection from or pedestal upon
the plate. The handle and the plate are then connected together flexibly, for
instance by a piece of indiarubber tubing. A perfect impression will thus be
always obtained, as the pressure will invariably be applied at or near the centre of
the plate, which is capable of moving relatively to the handle.

Improvements in and relating to Hand Stamps.
I, JOHN GARDNER of 3 Marine View, Knott End, Fleetwood in the County
of Lancaster, and formerly of "High Bank" Manchester Road, Altrincham in
the County of Cheshire, Typewriting Machine Manufacturer, do hereby declare
the nature of this invention, and in what manner the same is to he performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to hand stamps for endorsing and similar purposes, and
its object is to provide means whereby such stamps are prevented from forming
impressions which are heavier in one part than in another."
In carrying this invention into effect, the handle of the stamp is loosely or
movably connected to the plate carrying the printing surface, and is preferably in
contact with it at one point only.
A convenient method of constructing a stamp according to this invention is
illustrated by the accompanying drawing which will be hereinafter referred to.
The drawing represents the lower part in vertical section, and the upper part of
the handle in elevation.
The base of the handle has a circular recess formed in it coaxial with the axis
of the handle. In this recess there is fitted a short indiarubber tube T, the upper

page_text: end of which is closed except for a small hole through which the round headed
screw S can be passed into the handle as shewn. It is advantageous to interpolate
a metallic washer W between the head of the screw and the blank end of the india-
rubber tube. The plate P upon which the rubber or other printing surface E is
formed or attached, has at the centre of its upper surface, a circular projection or
boss B of such dimensions that it fits the rubber tube T and just bears upon the
round head of the screw S. The tube may be cemented upon the boss B by means
of shellac cement, marine glue or similar material.
With this construction it will be seen that the pressure will be transmitted to the
centre of the printing surface, even when the handle is held at a considerable angle
from the vertical, and that the printing surface when being used need not be exactly
at right angles with the axis of the handle, as in ordinary stamps.
The construction illustrated may be considerably modified, but so always as to
have a flexible connection between the handle and the plate, and only a central
point of contact. Thus, the rubber tube may have both ends open, and the upper
end may be cemented upon a projection from the lower end of the handle. The
upper end of the tube is in this case cemented upon the projection from the handle,
and the lower end upon the boss B. In either case the rubber tube may be
substituted by an equivalent spiral spring. I prefer however to employ the
construction illustrated as giving the best results in practice.
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. In hand stamps, constructing the handle and plate respectively independently
and in such a manner that pressure on the handle is transmitted to the centre of
the plate and connecting the two parts by a flexible connection, substantially as
and for the purpose hereinbefore described and as illustrated by the accompanying
drawing.
2. Hand stamps constructed substantially as hereinbefore described with
reference to the accompanying drawing.
