Improvements in certain Machines for Stamping, Printing, or
Embossing Woven or other Fabrics and Materials.
1, FRANCIS PRESTON, of Netherfield House, Kirkburton in the County of
York, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in machines for stamping printing or
embossing woven or other fabrics and materials and particularly to the type of
machine for which I obtained Letters Patent numbered 2267 and dated February
8th, 1889.
My first improvement consists in so arranging the holder or beam to which the
printing blocks platens or stamps are secured that it can be reversed so as to allow
the said stamps to be readily placed in position, or inspected and cleaned, and then
turned back again into their working position.
My second improvement consists in mounting the stamps so that they can be
readily changed in position in order to give a longitudinal or transverse impression
as required. A convenient mode of effecting this is to provide a square slide fitted
upon the back of each stamp which slides in the groove of the beam to any
required position; or instead of fixing a square slide to the back of the stamp the
latter may be secured in a holder fitted to slide in the beam as above described.
My third improvement consists in providing four screws for adjusting the height
of the table, these screws to be actuated by bevel or skew wheels so as to work the
said four elevating screws by simply turning two small wheels or handles placed in
a suitable position for being easy of access.
My fourth improvement consists in combining springs with the adjusting screws
of the table upon which the piece goods or other articles to be stamped are laid in
such manner that the springs will carry the table and piece or other article but will
yield to the pressure of the stamp when the latter is applied to the goods; but as
the stamp begins to rise again the springs also raise the table and article to the
initial position whereby a longer and more effective contact and better impressions
are obtained; or in place of the table resting upon springs as described I may allow
it to rest direct upon the adjusting screws, in which case propose to employ a
loose board placed on the above named table for the goods to rest upon and
arrange suitable springs between the board and the table so as to give the desired
elasticity.
My fifth improvement consists in so mounting the stop bar at the edge of the
table that it can be adjusted by a parallel motion whereby the size of the table can
be regulated according to the size of the article to be stamped and further the
article can also be made to occupy the proper position relatively to the stamp.
My sixth improvement consists in making the inking pad adjustable by means of
screws or equivalents in order to regulate the height of the bed.

Improvements in certain Machines for Stamping, Printing, or
Embossing Woven or other Fabrics and Materials:
1, FRANCIS PRESTON, of Netherfield House, Kirkburton in the County of
York; Civil 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:-
My invention relates to improvements in machines for stamping printing or
embossing woven or other fabrics and materials and particularly to the type of
machine for which I obtained Letters Patent numbered 2267 and dated February
8th 1889.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying four sheets of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a front elevation. Fig. 2 a side elevation and Fig. 3 a plan of a
stamping machine substantially of the construction specified in my aforesaid Patent
but fitted with my present improvements.
Figs. 4, 5 and 6 are detail views of the stamps fitted with square slides
according to my second improvement.
Fig. is a detail view of the stamp beam illustrating a modification or
alternative mode of carrying out my second improvement and
Figs. 8 and 9 are transverse vertical sections of Fig. 7 taken respectively on
the lines A B and C D.
In Figs. 1 to 3-a are the printing blocks or stamps, the beam or holder to
which they are secured, c the movable frame supporting the beam b, c the arms
jointed to the frame c and keyed upon the rocking shafts d, e the toothed wheels,
f the reciprocating rack fitted in slideways g on the machine frame g, h the
connecting rod, i the crank, the rotating crankshaft, & the inking pad or bed, I the
fabric to be printed resting on the table mi, n the colour roller traversed by the arms p
connected to the movable frame c, and o the colour trough from which the roller n
takes its ink or colour.
My first improvement consists in so arranging the holder or beam 6 to which the
printing blocks platens or stamps a are secured that it can be reversed so as to
allow the said stamps to be readily placed in position, or inspected and cleaned, and
then turned back again into their working position. To effect this 1 either turn the
ends of the beam or employ two separate studs g as shown which are fitted in each
end of the beam and also in the movable frame c and so act as pivots upon which
the beam can be turned up into the position indicated by dotted lines Fig. 2. The
beam can be secured in either position by pinching screws 7.
This simple arrangement of mounting the beam enables it to be readily reversed
in position and further has the additional advantage of enabling one beam to be
taken out and another substituted when required.
My second improvement consists in mounting the stamps a so that they can be
readily changed in position in order to give a longitudinal or transverse impression
as required. A convenient mode of effecting this is to provide each stamp a, as
shown in Figs. 4, 5 and 6, with a square slide a' which slides in the groove of the
beam to any.required position, each stamp being secured in its place by a screws
as shown in Fig. 1 as well as in Figs. 5 and 6. Between each stamp a is fitted a
dummy block or holder t the edges of which are roughened or serrated so that when
pressed together by the end screws u the stamps and holders are firmly secured in
their places. In the alternative or modified arrangement illustrated by Figs. 7, 8
and 9 instead of having the square slide on the back of each stamp a the latter is
simply gripped between the serrated or roughened edges of two of the holders,

page_text: each holder having a slide t¹ fitted in undercut grooves in the beam b. In this
case to change the stamps it is only necessary after reversing the beam to slacken
the screws u, then take out and reverse or substitute fresh stamps a then tighten
the screws again and again reverse the beam so as to bring it back to its
working position.
•
My third improvement consists in providing four screws for adjusting the
height of the table m, these screws are actuated by bevel or skew wheels w
so as to work the four elevating screws by simply turning two small wheels a
or handles placed in a suitable position for being easy of access.
My fourth improvement consists in combining springs y with the adjusting
screws of the table m upon which the piece goods or other articles to be
stamped are laid in such manner that the springs y will carry the table and
piece or other article but will yield to the pressure of the stamp when the latter
is applied to the goods; but as the stamp begins to rise again the springs y also
raise the table m and article thereon to the initial position whereby a longer and
more effective contact and better impressions are obtained; or in place of the
table m resting upon springs as described I may allow it to rest direct upon the
adjusting screws t, in which case I propose to employ a loose board placed on
the above named table for the goods to rest upon and arrange suitable springs
between the board and the table so as to give the desired elasticity.
My fifth improvement consists in so mounting the stop bar at the edge of the
table m that it can be adjusted by a parallel motion. This I effect by connecting
the stop har by two links 2 to fixed centres 3 and I employ a set screw or
equivalent means to retain the said bar in position when adjusted.
In combination with the stop bar I also employ an ordinary adjustable end stop
bar 5 and pinching screw 6 or I may provide this stop bar 5 with a parallel
adjusting motion similar to that of the bar z.
By these means the size of the table m can be regulated according to the size of
the article to be stamped and further the article can also be made to occupy the
proper position relatively to the stamp.
My sixth improvement consists in making the inking pad k adjustable by means
of screws 7 or equivalents in order to regulate the height of the bed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is:-
In a machine of the type specified for stamping printing or embossing woven or
other fabrics and materials-
1. Mounting the beam or holder to which the printing blocks platens or stamps
are secured so that it can be readily reversed in position substantially as and for
the purposes herein set forth.
2. Mounting the printing blocks platens or stamps substantially in either of the
two modes herein set forth so that they can be readily changed in position in order
to give a longitudinal or transverse impression as required.
3. The combination with the table m, of the two pairs of adjusting screws
actuated by two wheels or handles and gearing substantially as and for the purpose
herein set forth.
4. The combination with the adjusting screws of the table m, of an arrangement
of springs substantially as and for the purposes herein set forth under the fourth
head of my improvements.
5. Mounting the stop bar or bars on the table m so that it or they can be
adjusted with a parallel motion to regulate the size of said table according to the
size of the article to be stamped substantially as herein set forth under the fifth head
my improvements.
of
6. The combination with the inking pad k, of the screws 7 or equivalents for
regulating the height of the bed substantially as herein set forth.

page_text: 7. The combined arrangement of parts constituting the improved machine sub-
stantially as herein shown and described.
