IMPROVEMENTS IN STAMPS OR HAMMERS WORKED BY POWER."
Year: 1856

page_text: LETTERS PATENT to William Carr Hutton, of Sheffield, in the County of
York, Manufacturer, for the Invention of "IMPROVEMENTS IN STAMPS
OR HAMMERS WORKED BY POWER."
PROVISIONAL SPECIFICATION left by the said William Carr Hutton, at
the Office of the Commissioners of Patents, with his Petition, on the
30th May 1856.
I, WILLIAM CARR HUTTON, of Sheffield, in the County of York, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN STAMPS OR HAMMERS WORKED BY POWER," to be as follows:-
The improvements relate to means for effecting the lifting and falling move-
inent to the stamp or hammer head.
The stamp or hammer head is, by means of a suitable band, strap, or chain
attached to a drum or pulley, affixed to an axis, supported in suitable bearings,
and whose ends are capable of being connected, by clutch box or other means,
with cones, or other such means, driven by a band or strap from a steam
engine, or other suitable power. The cones or such driving means at each
end of the shaft or axis are caused to rotate in opposite directions, and the
connecting means to the shaft are so arranged, that when one is connected

page_text: so as to move such shaft, the other is free of it. The connections may be
effected by a forked lever or other means. When the blow is struck by the
stamp or hammer head, advantage is taken of the momentum given by the
falling hammer head or stamp to assist its elevation again. The stamp or
hammer head is guided by suitable guides.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Carr Hutton in the Great Seal Patent Office on the
28th November 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CARR HUTTON, of Sheffield, in the County of York, Manufacturer, send
greeting.
WHEREAS ITer most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Iler reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Carr Hutton, Her special licence that I, the said William Carr
ITutton, my executors, administrators, and assigns, or such others as I, tho
said William Carr Hutton, 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 "IMPROVE-
MENTS IN STAMPS OR HAMMERS WORKED BY POWER," upon the condition (amongst
others) that I, the said William Carr Hutton, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
scals, should particularly describo and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Carr Hutton, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
The improvements relate to means for effecting the lifting and falling move-
ment to the stamp or hammer head. The stamp or hammer head is, by means

page_text: ef a suitable band, strap, or chain, attached to a drum or pulley, affixed to
an axis supported in suitable bearings, and whose ends are capable of being
connected by a clutch box, or other means, with cones, or other such means,
driven by bands or straps from a steam engine, or other suitable power The
cones, or such driving means at each end of the shaft or axis, are caused to
rotate in opposite directions, and the connecting means to the shaft are so
arranged, that when one is connected, so as to move such shaft, the other is
free of it. The connections may be effected by a forked lever or other means.
When the blow is struck by the stamp or hammer head, advantage is taken of
the momentum given by the falling hammer head or stamp to assist its cleva-
tion again. The stamp or hammer head is guided by suitable guides.
But that the nature of my said Invention, and in what manner I carry the
same into effect, may be fully understood, I will proceed to describe the
Drawing annexed.
"
DESCRIPTION OF THE DRAWING,
which represents an elevation (partly in section) of a stamp or hammer con-
structed according to my Invention. a is the stamp or hammer head; b, b;
are guides, by which the same is guided in its movement; c is a strap (or it
may be a band or chain), one end of which is connected to the hammer head a,
and the other to the drum d, in such manner, that as the drum d rotates in
one or other direction, it may, by winding up the strap c, raise the stamp or
hammer head a; e is a roller to guide the strap c. The drum is affixed
upon a shaft or axis f, which is supported in bearings g, 9, in which it is not
only capable of a rotatory but also of an endway motion, in order that the hollow
cones h, h', affixed, one at each end of such shaft or axis f, may be capable of
being slided alternately upon one or other of the cones o, o', affixed respectively
to shafts and m. These shafts are supported separately in bearings n, n,
and they have affixed upon them driving pullies (one i the other k), acted upon
by straps or bands, by which they receive rotatory motion in opposite directions,
as indicated by the arrows, from a steam engine or other suitable power:
Thus it will be seen, that when, by the sliding of the shaft or axis f to the left,
the hollow cone h is made to bear upon the solid surface of the conc o, a
rotatory motion will be given to the shaft or axis f in the direction of that of
the pulley i, and that when, by the sliding of the shaft or axis f in the opposito
direction, the hollow cone is caused to bear upon the cone o¹, the shaft or
axis f will receive a rotatory motion in the direction of that of the pulley k.
The sliding of the axis or shaft f, according to the arrangement shewn, is
eflected by the lever p, which turns upon the fixed pin q, and at its upper end

page_text: is formed into a fork r to embrace the collar s, as is well understood; but this
may be varied.
In using the stamp, the workman by pushing the handle t, for example, to
the left, causes the hollow cone h' to embrace, and by the friction of the
surfaces to hold upon the cone o', when the pulley & will receive a rotatory
motion in the direction of the pulley to lift the weight. When he has
thereby raised the hammer head sufficiently high, the workman moves the
lever handlet a little to the right, sufficient to disengage the hollow cone h¹
from the cone o¹, when the hammer a falls by its own weight upon the die u.
By the descent of the hammer a, a rotatory motion is imparted to the pulley
d, in the direction of that of the pulley i, and the workman, by moving the
handlet still further to the right at the moment when the hammer a falls
upon the die u, causes the hollow cone h to slide upon and engage with the
cone o, when the band c will be coiled upon the pulley d in a direction contrary
to that in which it was previously coiled, and the hammer will be again raised.
When the hammer head a is again at the required height, the workman moves
the handle t to the left, and thereby first disengages the cone h from the cone o
to admit of the fall of the hammer head, and then re-engages the cone h¹ with
the cone o', and so on, the hammer a being raised by engaging alternately the
shaft into the shafts 7 and m, such shafts having, as already stated, motions
given them in opposite directions. After the shaft f has been disengaged from
either of the shafts 1 or m, the descent of the hanuner gives to the pulley d
momentum in a direction opposite to that of the shaft from which the shaft f
has just been rotating, and in a direction similar to that of the shaft with
which it is about to be engaged. I sometimes dispense with one of the shafts
7 or m, together with the cones acting with it, and use only one shaft with a
cone, and capable of acting with a hollow cone on one end of the shaft f.
When thus acting, supposing the shaft to be retained with its cone o, to
receive the hollow cone h, and the axis m, and parts acting therewith, to be
removed, by moving the handle t to the right the hollow cone h will engage
with the cone o, and the hammer a will be raised by the pulley & coiling up
the band c, the said pulley & having motion in the direction of the pulley i.
When the hammer a has been raised sufficiently high, the handle t is moved
to the left, the hammer a falls, and at the instant of its striking the die u the
handle is moved to the right, the hollow cone again engages with the cone
o, and the hammer a is again raised. I prefer, however, to carry my Invention
into effect by the use of the two shafts l, m, and parts acting therewith, as first
described, and represented in the accompanying Drawing.
Having now described the nature of my said Invention, and the manner of

page_text: carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein shown and described, as the same may be
varied without departing from the peculiar character of my Invention; and
although I have shewn conical surfaces as the means of effecting the engage-
ment and disengagement of the parts, other frictional surfaces or clutch box
arrangements may be employed. But what I claim is, the so arranging and
combining parts in connection with stamps or hammers worked by power, that
the raising and falling of the stamp or hammer head may be effected by the
alternate engaging and disengaging of the parts operating with the driving
mechanism, in manner substantially as explained.
In witness whereof, I, the said William Carr Hutton, have hereunto set
my hand and seal, this Twenty-first day of November, in the year of
our Lord One thousand eight hundred and fifty-six.
WILLIAM CARR HUTTON. (L.S.)
