COMPLETE SPECIFICATION.
An Improved Portable Stamping Machine, specially applicable
for Stamping Names or Initials in Hats, Boots, and similar
articles.
We, EDWARD PLUMPTON of 160 Monday Street, in the City and County of
Newcastle-on-Tyne, Compositor and THOMAS THOMPSON of 12 Abbey Street,
Gateshead in the County of Durham, Fitter 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 an improved portable stamping machine specially
applicable for stamping names or initials in hats, boots and similar articles.
We will describe our invention with reference to the accompanying drawings, in
which
Figure 1 shows a general side elevational view of the machine, Figure 2 being
an end view of the same.
Figure 3 is a section on line y in Figs. 1 and 2 and
Figure 4 is a sectional elevation of a detail hereinafter again referred to and
throughout this description like marks of reference signify like parts.
Referring to the drawings, A is a cast iron standard or frame of the general
design shown and on this frame at A' a lever A² is centred. This lever is used to
work the stamping ram A³ up and down in its guide. The guide is formed by
somewhat setting back the metal of the frame A at A* and by securing the cover-
piece A to the frame by screws or equivalent connections A. The ram A³ thus
works up and down within the space formed between the side of the frame A
and the cover A'. The ram is provided with a slot 8 in which the lever works
to actuate the ram and the ram head is formed with an aperture 9 therein into
which when the ram head is at its upstroke, the gas burner 10 protrudes its flame
to warm the metal of the ram head. On the back of the cover A' is formed a gas
pipe 11, terminating at its upper end in a tapered nozzle to take a flexible gas
tube 12 and at its lower end a gas burner is fitted as shown. At the head of the
frame A, a guide ring 13 is secured through which the spindle of the ram projects
and between this ring and the nut 14 on the ram spindle head a coil spring 15 is
placed, adjustable as to its amount of compression by the nut 14. The spring thus
acts to hold the ram up so that in working the gas jet or flame may act on the ram
head as above described.
The ram head is formed with a wedge shaped lip 16 thereon so that when the
cover piece 17 is secured as shown to the end of the rain head, the projecting
lip 18 thereon presses tightly against the edge of the composition die 19, containing
the name or initial or device required to be stamped or impressed in the leather 20,
and prevents any movement thereof in its seat.
For stamping or printing in ink, a separate type box 21 is secured to the ram
head as shown in Fig. 4 by screws 22.
The type 24 is then fitted in the part of the box projecting below the ram and
secured in position by lateral screws 23.
When stamping in gold leaf the lever is lifted up and forced down again against
a sheet of gold leaf 25 which in turn is of course laid over the place on the
leather 20 where the impression is desired to be. This leather may overlie a
leather cushion 26 recessed in the metal as shown. A thin sheet of paper may
intervene between the ram head and the gold leaf for the purpose of facilitating
the application and working of the leaf. A sprinkling of albumenized powder is
put on the leather prior to laying the gold leaf in position upon it.
The ram head may be secured adjustably by screwing or otherwise to the ram
spindle.

page_text: In this manner names, initials or other indicia may be readily stamped or impressed
upon the leather or equivalent substance in gold or silver leaf or by printing in
ink as required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
บ
1. An improved portable stamping machine for stamping names, initials or other
indicia in hats, boots and similar articles consisting in the combination with a
suitable upright frame of a lever, the said lever being pivotted on the frame and
arranged to actuate a vertical-acting ram fitted in guides on the frame, the said
ram being held normally at the upstroke by means of an adjustable coil spring so
that a gas jet may operate to heat the ram head the downstroke whereby the
impression is effected being performed in opposition to the spring pressure the
several parts being arranged and adapted to operate substantially as herein set
'forth.
2. The combination with the ram head of a portable stamping machine such as
has been described and claimed in Claim 1 of a type box to hold type for printing,
formed, arranged and adapted to operate substantially as herein set forth.
Dated this 23rd day of November 1892.
