PROVISIONAL SPECIFICATION left by Daniel Benjamin Herts at the
Office of the Commissioners of Patents, with his Petition, on the 10th
February 1857.-A communication.
- I, DANIEL BENJAMIN HERTS, of Bunhill Row, in the County of Middlesex,
Merchant, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN APPARATUS FOR STAMPING AND EMBOSSING," to be as follows:-
This Invention relates to a peculiar construction and arrangement of appa-
ratus for facilitating the printing or embossing of stamps or marks on paper,
cloth, or other fabrics.
The improved apparatus consists of a stand fitted with two beds, the one
answering as a dabber when coloring matter is to be used, and the other
serving to carry the requisite force when the apparatus is to be employed for
embossing. Above these beds is an arm or stamp carrier, which vibrates
horizontally on a fixed centre near the back of the stand, so as to admit of
the stamp being brought alternately over each of the two beds. A small
helical spring contained within the carrier serves to keep the stamp elevated
when not acted upon by the striker, which consists of a lever moving with
the carrier and acted upon by a powerful blade or other spring, so as to give
an effective blow on the top of the stamp or die spindle. The back end of
this lever or striker works in the groove of a fixed cam of a peculiar con-
struction, whereby a figure of 8 motion is imparted to the end of the lever

consists of two angular projections placed side by side, with their points
or apices described inwards or towards each other, a sufficient space being
left between the two apices for the free passage of the end of the striker.
Midway between the apices of the projecting angles is a hinged tongue or
guiding piece which is long enough to bear against the under side of either
point when deflected laterally by the passage of the end of the striker.
As this end of the striker is traversed along, it passes down the inclined
groove above the projection No. 1, and on coming in contact with the tongue
piece it pushes it to one side, and is then guided along the under side of the
tongue to the under side of projection No. 2. On arriving at the end of this
projection it enters a vertical slot, and the action of the powerful blade spring
instantly brings down the now released striker and imparts a smart blow to
the die or stamp. The same movement is repeated at the return stroke, the
cud of the striker first passing along the upper side of No. 2, then along the
under side of the again deflected tongue and along the under side of No. 1,
being finally released. again to give another blow on arriving at the vertical
groove of projection No. 1.
It will thus be obvious that the end of the striker has during its two
traverses described a figure of 8 motion and given two blows to the die for
stamper one over each bed.
A buffer of india-rubber or other suitable material is placed on the carrier
below the striking end of the lever, for the purpose of preventing fracture of
the apparatus by the sudden force of the blow.
A handle in front of the carrier facilitates its traverse from one bed to
the other.
