PROVISIONAL SPECIFICATION left by the said Godfrey Steinhoff at the
Office of the Commissioners of Patents, with his Petition, on the
8th January 1873.
I, GODFREY STEINHOFF, of Suffolk Lane, Thames Street, in the
County of Middlesex, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED CONSTRUCTION OF HAMMER FOR IMPRESSING'
OB PRINTING NUMBERS, LETTERS, OR OTHER MARKS IN OR UPON TIMBER AND OTHER
SUBSTANCES, AND AN IMPROVED INKING OR COLORING APPARATUS IN CONNECTION

page_text: THEREWITH," a communication to me from abroad by H. Schmidt, of
Schindler's Werk, near Schneeberg, Saxony, to be as follows:-
The main object of this Invention is to facilitate the marking of
timber with successive numbers or letters, and its essential feature is
the use of numbering or lettering wheels or rings in the form of a
hammer, the wheel carrying the units being operated by a lever so that
it revolves and presents its numbers or letters successively at the
striking face.
A second wheel or wheel of tens is turned by hand to bring its
numbers successively to the striking face, and there may be a third
wheel for hundreds, a fourth for thousands, and so on, all moved in the
same manner as that of tens; or in lieu of the third and succeeding
wheels slides may be used to receive a single type as may be required.
The Invention also relates to a portable coloring or inking pad for
inking these numbering hammers.
The Invention will be best understood by reference to the accompany-
ing sheet of Drawing upon which Figure 1 represents an elevation or side
view of a hammer ombodying this Invention, fitted with two movable
numbering rings or wheels and two slides for securing single type, and
Figure 2 is an end view of the same; A is the handle carrying at its
outer end the two wheels B and C, and also the two slides D and E, into
which are secured by means of the screw a the necessary figures or
letters; F is the hand lever which works between the ribs or projections
on the inner face of the unit wheel B (shown separately, Fig. 5) and
thus causes it to revolve; G is a spring catch lever by means of which
the second wheel C is moved through the requisite distance and stopped
so as to always present the figure required. In working with this
hammer strike with that face of the hammer indicated by the letters.
B, C, D, E, upon which is the type for the numbers you require.
Commencing to number with 1, take out the inserted type, put the
wheel of tens with its blank surface opposite No. I., and strike from 1 to
9; in order to use the following numbers hold the handle rather loosely,
press the lever F with the left hand, and seize the handle again firmly.
The unit wheel is always moved to the extent of one number by a single
pressure, and loosening of the grip on the lever. To turn the wheel
of the tens, press back the spring G (used for stopping), push it sideways
to the next incision, then back again to its original place, when the

page_text: wheel C will have been turned by one number. The screw a for
securing the type in the slides D, E, must be kept very tight to prevent
the numbers falling out when numbering.
Figure 3 is a side view of a hammer embodying this Invention and
fitted with four movable wheels, and Figure 4 is an end view of same.
H is the handle carrying the four wheels I, K, L, M, and also the
lever N; O is a sliding catch which slides in the groove on the outer
face of the wheels and locks them all together when once adjusted. In
using this hammer strike with the face indicated by the letters
I, K, L, M. To change the number hold the handle rather loosely,
press the lever N right down with your left hand and grip the handle H
and the outer end of the lever N again with a firm grasp to strike
another number upon the timber, and so on until the unit whoel has.
made an entire revolution, then press down the lever N, push back the
slide O, and turn the wheel K until you get the number required on this
wheel, then lock again with the slide O, and so on successively, using the
wheels L and M for the hundreds and thousands. To turn the last
wheel M tho slide O must be almost entirely pulled out. If the
numbering commences by 1 the blank surfaces of the three remaining
wlicels must be in line with that number on the striking face.
Figure 5 is a plan of the unit wheel showing general arrangement of
ribs or projections on the same, against which the lovers F and N work,
and by means of which the wheel is caused to revolve. Figure 6
represents a front and end view of the ink pad with lid open, b is the
self inking pad forming one of the faces of the ink reservoir, c the neck
through which the reservoir is filled with printers' ink.
This pad is
fastened by straps from c, e, round the waist of the hammerer, so that
the pad rests against his left thigh. In pressing the hammer on the
pad it should not be rubbed but rather rolled over it and the tin
should always be kept full, oven when not in use, and the pad downwards,
so that it may always be ready for use.
Figure 7 is a plan and elevation of spanner for adjusting set screw
a and nut d.
It will be evident that hammers of this construction might be used

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Godfrey Steinhoff in the Great Scal Patent Office
on the 5th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GODFREY
STEINHOFF, of Suffolk Lanc, Thames Street, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of January, in the year
of our Lord Ono thousand cight hundred and seventy-three, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Godfrey Steinhoff, Her
special licence that I, the said Godfrey Steinhoff, my executors, adminis-
trators, and assigns, or such others as I, the said Godfrey Steinhoff, my
executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "A
NEW OR IMPROVED CONSTRUCTION OF HAMMER FOR IMPRESSING OR PRINTING
NUMBERS, LETTERS, OR OTHER MARKS IN OR UPON TIMBER AND OTHER SUBSTANCES,
AND AN IMPROVED INKING OR COLORING APPARATUS IN CONNECTION THEREWITH,'
a communication to me from abroad by H. Schmidt, of Schindler's
Work, near Schneeberg, Saxony, upon the condition (amongst others)
that I, the said Godfrey Steinhoff, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
"
NOW KNOW YE, that I, the said Godfrey Steinhoff, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement :-
The main obiect of this Invention is to facilitate the marking of timber

page_text: use of numbering or lettering wheels or rings in the form of a hammer,
the wheel carrying the units being operated by a lever so that
it revolves and presents the numbers or letters successively at the
striking face.
A second wheel or wheel of tens is turned by hand to bring its
numbers successively to the striking face, and there may be a third
wheel for hundreds, a fourth for thousands, and so on, all moved in
the same manner as that of tens, or in licu of the third and
succeeding wheels slides may be used to receive a single typo as may
be required.
The Invention also relates to a portable coloring or inking pad for
inking these numbering hammers.
The Invention will be best understood by reference to the ac-
companying Sheet of Drawing, upon which Figure 1 represents an
clevation or side view of a hammer embodying this Invention fitted with
two moveable numbering rings or wheels, and two slides for securing
single type, and Figure 2 is an end view of the same. A is the handlo
carrying at its outer end the two wheels B and C, and also the two
slides D and E, into which are secured by means of the screw a tho
necessary figures or letters; F is the hand lever which works between the
ribs or projections on the inner face of the unit wheel B (shown separately,
Fig. 5) and thus causes it to revolve; G is a spring catch lever by means
of which the second wheel O is moved through the requisite distance,
and stopped so as to always present the figure required. In working
with this hammer, strike with that face of the hammer indicated
by the letters B, C, D, E, upon which is the type for the numbers
you require. Commencing to number with 1, take out the inserted type,
put the wheel of tens with its blank surface opposite No. I., and strike
from 1 to 9. In order to use the following numbers hold the handle
rather loosely, press the lever F with the left hand, and seize the
handle again firmly. The unit wheel is always moved to the extent of
one number by a single pressure and loosening of the grip on the
lever. To turn the wheel of the tens, press back the spring G (used for
stopping) push it sideways to the next incision, then back again to its
original place, when the wheel C will have been turned by one number.
The screw a for securing the type in the slides D, E, must be kept very
tight to prevent the numbers falling out when numbering.

page_text: | Figure 3 is a side view of a hammer embodying this Invention and
fitted with four movable wheels, and Figure 4 is an end view of
same.
H is the handle carrying the four wheels I, K, L, M, and also
the lever N; O is a sliding catch which slides in the groove on the outer
face of the wheels and locks them all together when once adjusted. In
using this hammer, strike with the face indicated by the letters
I, K, L, M. To change the number, hold the handle rather loosely,
press the lever N right down with your left hand, and grip the handle H
and the outer end of the lever N again with a firm grasp to strike
another number upon the timber, and so on until the unit wheel has
made an entire revolution. Then press down the lever N, push back
the slide O, and turn the wheel K until you get the number required on
this wheel, then lock again with the slide O, and so on, successively
using the wheels L and M for the hundreds and thousands. To turn
the last wheel M, the slide O must be almost entirely pulled out. If the
numbering commences by 1 the blank surfaces of the three remaining
wheels must be in line with that number on the striking face.
Figure 5 is a plan of the unit wheel showing general arrangement of
ribs or projections on the same, against which the levers F and N work,
and by means of which the wheel is caused to revolve. Figure 6:
represents a front and end view of the ink pad with lid open; b is the
self inking pad forming one of the faces of the ink reservoir; c, the
neck through which the reservoir is filled with printers' ink. This pad
is fastened by straps from e, e, round the waist of the hammerer so that
the pad rests against his left thigh. In pressing the hammer on the pad
it should not be rubbed but rather rolled over it, and the tin should
always be kept full, even when not in use, and the pad downwards so.
that it may always be ready for use.
Figure 7 is a plan and clevation of spanner for adjusting set screw a
and nut d.
It will be evident that hammers of this construction might be used
for numbering or marking other substances than timber.
Having now described and ascertained the nature of the said Invention
communicated to me as aforesaid, I would have it understood that I do
not limit myself to any particular dimensions in the construction of 3
these improved hammers and apparatus connected therewith nor to the
use of any particular material in their manufacture, nor to the precise

page_text: forms shown on the Drawing, as such may be varied while retaining the
essential and novel characteristics of this Invention, and that what I
claim as secured to me by the herein-before in part recited Letters
Patent, is,―
Firstly. The use of numbered or lettered wheels in the form of a
hammer, substantially as and for the purposes above set forth.
Secondly. The use of a unit wheel turned and fixed, substantially as
hercin-before set forth.
Thirdly. The use of the slides for securing single type, substantially as
and for the purpose above set forth.
Fourthly. The use of the apparatus for inking or coloring the letters
or numbers, substantially as herein-before set forth.
In witness whereof, I, the said Godfrey Steinhoff, have hereunto set
my hand and scal, this Third day of July, in the year of our
Lord One thousand eight hundred and seventy-three.
GODFREY STEINHOFF. (L.S.)
