page_text: LETTERS PATENT to Sam Hague, of Westwinsted, Litchfield County, in
the State of Connecticut, America, but having a temporary residence
in the Town and County of the Town of Nottingham, Cutler, for the
Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR RAISING
HAMMERS AND STAMPING MY DAM
"
Sealed the 29th August 1862, and dated the 1st March 1862.
PROVISIONAL SPECIFICATION left by the said Sam Hague at the
Office of the Commissioners of Patents, with his Petition, on the
1st March 1862.
I, SAM HAGUE, of Westwinsted, Litchfield County, in the State of Con-.
Decticut, America, but having a temporary residence in the Town and County
of the Town of Nottingham, Cutler, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR RAISING
HAMMERS AND STAMPING WITH THEM HOT OR COLD METALS," to be as follows:-
My Invention consists of certain new mechanical arrangements and com-.
binations of parts herein-after mentioned. I use a base plate or block of
any convenient size, having on the top side thereof fixed or adjustable guides,
the inner sides of these guides being V or otherwise shaped, upon which -
slides the hammer in the usual way. A rod is hinged at its lower end to
the top side of the hammer, the other end of the rod is tapped for part-of

page_text: I
its length to receive two lock nuts; the upper end of the rod is passed through
a block which has a stud or projection at the back thereof; the stud is passed
through one of a series of holes in an arm keyed fast on the end of a shaft.
sometimes, instead of passing the stud through one of the holes in the arm,
use an arm having a slot in it, and pass through the outer end of the arm
a screw, which also passes through the stud or projection which is tapped
to receive it, by which means I set the block at any required distance from
the centre of the shaft, and I secure the block, when so set, by nuts placed on
that part of the stud or projection which passes beyond the slot in the arm.
The shaft on which the arm is secured is carried by two bearings in a cast-
iron frame, and between the bearings on the shaft is keyed fast a double-
ended lever, one end of which is provided with a dog, which is prevented
from falling one way by a spring; next to the double-ended lever is placed
a pipe or boss, which is provided on the end next the double-ended lever with
a ratchet wheel; one half of this ratchet wheel is covered by a plate or cam of
semicircular shape and of slightly larger diameter than the ratchet wheel. This
cam is supported by a cross casting in the frame, and in addition to the cam there
is also a double-ended lever, one end of which corresponds to and forms a con-
tinuation of the fixed cam. This lever is capable of being raised or lowered by
a dog which may be held where placed by a catch spring or other means.
When the rod is raised the end of the lever will form a continuation of the
cam and prevent the dog on the end of the first-mentioned double-ended
lever from dropping into the teeth of the ratchet wheel, so that the hammer
will not be raised by the revolution of the ratchet wheel, but will remain on
the bottom centre, and when the hammer is to be raised the rod is pulled
down, and the dog will fall into the ratchet wheel and the hammer will be
raised. Under the shaft is placed a lever having a stop thereon against
which the opposite end of the lever carrying the dog will stop, thereby keeping
the hammer on the top centre until the stop lever is pulled down and the
dog lever is set free to raise the hammer again, the hammer being constantly
raised by the ratchet wheel moving the, shaft round, the hammer falling by
its own weight as long as the stop lever is held down. The stop lever. is
provided with a spring over which the end of the dog lever passes, the end
then resting between the spring and the stop. The other end of the boss to
which the ratchet wheel is secured is provided with a pulley which is driven
by a belt from another pulley or is driven by hand or by power. Sometimes
instead of using a pulley on the end of the boss, I place a large toothed wheel
which gears into a smaller one on an additional shaft, on which is also
keyed a larger toothed wheel gearing into a smaller wheel on a boss revolving

page_text: loosely on the first-mentioned shaft which boss is provided with a pulley for
a belt moved as described; both these bosses are prevented from sliding
endwise on the shaft by collars. I use the additional shaft and gearing
when a heavy hammer is to be lifted..
SPECIFICATION. in pursuance of the conditions of the Letters Patent, filed
by the said Sam Hague in the Great Seal Patent Office on the
1st September 1862.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAM
HAGUE, of Westwinsted, Litchfield County, in the State of Connecticut,
America, but having a temporary residence in the Town and County of the
Town of Nottingham, Cutler, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Sam Hague, Her special licence that I, the said Sam
Hague, my executors, administrators, and assigns, or such others as I, the
said Sam Hague, 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, exer-
eise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR RAISING HAMMERS AND STAMPING WITH THEM
HOT OR COLD METALS," upon the condition (amongst others) that I, the said
Sam Hague, 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 Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said. Sam Hague, 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 thereof, reference being had to the accompanying Drawings, and to
the letters and figures marked thereon, that is to say :-
My Invention consists of certain new mechanical arrangements and com

page_text: .binations of parts, as herein-after mentioned. I use a base plate or block of any
convenient, size, having on the top side thereof fixed or adjustable guides, the
inner sides of these guides being V or otherwise shaped, upon which slides the
hammer in the usual way. A rod is hinged, at its lower end to the top side of
the hammer, the other end of the rod is tapped for part of its length in order
to receive two lock nuts; the upper end of the rod is passed through a block,
which has a stud or projection at the back thereof; the stud is passed through
one of a series of holes in an arm keyed fast on the end of a shaft. I some-
times, instead of passing the stud throngh one of the holes on the arm, use an
arm having a slot in it, and pass through the outer end of the arm a screw,
which screw also passes through the stud or projection which is tapped to
receive it, by which means I can set the block at any required distance from
the centre of the shaft, and I secure the block, where set, by means of nuts
placed on that part of the stud or projection which passes beyond the slot in
the arm.
The shaft on which the arm is secured is carried by two bearings in
a cast-iron frame, and between the bearings on the shaft is keyed fast a
double-ended lever, one end of which is provided with a dog; this dog is pre-
vented from falling one way by a spring, and next to the double-ended lever is
placed a pipe or boss, which is provided on the end next the double-ended
lever with a ratchet wheel; one half of this ratchet wheel is covered by a plate
or cam of a semicircular shape, and of slightly larger diameter than the ratchet
wheel. This cam is supported by a cross casting in the frame, and in addition
to the cam there is also a double-ended lever, one end of which corresponds to
and forms a continuation of the fixed cam. This lever is capable of being
raised or lowered by means of a dog, which may be held where placed by a
catch, spring, or by other suitable means. When the rod. raised, the end of
the lever will form a continuation of the cam, and will prevent the dog on the
end of the first-mentioned double-ended lever from dropping into the teeth of
the ratchet wheel, so that the hammer will not be raised by the revolution of
the ratchet wheel, but will remain on the bottom centre; and when the
hammer is to be raised the rod is pulled down, and the dog will fall into the
ratchet wheel, and the hammer will be, raised. Under the shaft is placed a
lever, having a stop thereon, against which the opposite end of the lever
carrying the dog will stop, thereby keeping the hammer on the top centro
until the stop lever is pulled down and the dog lever is set free to raise the
hammer again, the hammer being constantly raised by the ratchet wheel
moving the shaft round, the hammer falling by its own weight as long as the
stop lever is held down. The stop lever is provided with a spring, over which
the end of the dog lever passes, the end.then resting between the spring and

page_text: the stop. The other end of the boss to which the ratchet wheel is secured is
provided with a pulley, which is driven by a belt from another pulley, or is
driven by hand or by power. Sometimes, instead of using a pulley on the end
of the boss I place a large toothed wheel which gears into a smaller one on
an additional shaft, on which is also keyed a larger toothed wheel gearing into
a smaller wheel on a boss revolving loosely on the first-mentioned shaft, which
boss is provided with a pulley for a belt, moved as described. Both these
bosses are prevented from sliding endwise on the shaft by suitable collars.
I use the additional shaft and gearing when a heavy hammer is to be lifted.
Having thus set forth the nature of the said Invention, I now proceed to
explain the same more particularly, and the manner of performing it with
reference to the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1, Sheet 1, is a plan of my improved machinery, and some of the
parts are shown in section; Figure 2, Sheet 2, and Figure 2A, Sheet 3, repre-
sent the upper and lower halves respectively of a sectional side view of the
In the above Figures the apparatus is represented as supported by a
main framing of cast iron. Figure 3; Sheet 4, and Figure 3A, Sheet 5, repre-
sent similar portions of an end view, with a main framing of wood in lieu of
cast metal.
same.
The several corresponding parts in each of these Figures being lettered
alike, the following description will therefore apply to each.
A, A, A, represents the main framing, the uprights of which if made of
wood, as shown in Figure 3A, Sheet 5, are let into horizontal timbers B, of a
convenient length; but if made of iron they are let into blocks of stone B', as
shown on Sheet 3. The uprights are secured together at their upper end to
horizontal bearers C, which bearers are connected together by cross bearers D,
and which are further strengthened by stays D', thereby forming a firm
bearing for the parts herein-after. referred to. E represents a base plate or
block, having on the top side thereof fixed guides, or the guides may be made
adjustable, as shewn, in which case the lower ends of these guides F are held
securely in position by screws and nuts E¹, the screws passing through lugs E³,
cast on the base plate or block E; the upper ends of the guides are held by
similar screws and nuts, the screws passing through lugs cast on the frame E³,
which is bolted to the upper part of the main framing; the inner sides of the
guides may be V-shaped or otherwise shaped, and upon them the hammer G
slides in the usual way; the under side of the hammer is recessed for the
purpose of receiving a steel face plate or die, as required, such face plate or

page_text: die being secured to the hammer by any required number of screw bolts, which
pass through holes cast in the hammer G.
The following arrangement and combination of parts will more fully explain
my Invention: A rod G' is hinged at it's lower end to the top side of: the
hammer; the other end of this rod is tapped for a part of its length to receive
two lock nuts G², and the upper end of the rod is passed through a block G³,
which has a stud or projection at the back; the stud is passed through one of
a series of holes in an arm H, and is held fast by a nut at the back of the
arm, which is keyed fast on the end of a shaft. I. Sometimes; instead of
passing the stud through one of the holes in the arm, I use an arm liaving a
slot in it, and through the outer end of the arm I pass a screw, which screw
also passes through the stud or projection on the block G³, which is tapped: to
receive it, by which means I can set the block at any required distance from
the centre of the shaft, and I secure the block where set by means of nuts
placed on that part of the stud or projection which passes beyond the slot of
the arm. The shaft I is carried by two bearings in a cast-iron frame: I',
secured on the top of the main framing. Between the bearings on the shaft I
is keyed fast a double-ended lever K, one end of which is provided with a dog
K', which is kept within the teeth of the ratchet wheel by a spring, except
when lifted clear of the teeth by a cam and lever hereafter mentioned. Next
to the double-ended lever is placed a pipe or boss L, which is provided on the
end. next the double-ended lever with a ratchet wheel L', one half of which is
covered by a plate or by a cam L2, of a semicircular shape and of slightly larger
diameter than the ratchet wheel. This plate or cam is supported by a cross
casting I2 in the frame. I', and in addition to the cam there is a double-ended
lever M, one. end of which corresponds to and forms a continuation of the
cam L. This lever is capable of being raised or lowered by means of a rod,
which may be held where placed by a catch, spring, or by other suitable con-
trivance. When the rod is raised, the end of the lever will form a continuation
of the cam, and will prevent the dog on the end of the lever K from dropping
into the teeth of the ratchet wheel, so that the hammer will not be raised by
the revolution of the ratchet wheel, but will remain on the bottom centre, and
when the hammer is required to be raised the rod is to be pulled down, where-
upon the dog will fall into the ratchet wheel, and the hammer will be raised.
Under the shaft is placed a lever N, having a stop upon it, with which the
opposite end of the lever carrying the dog will come in contact, and thus stop
it and thereby keep the hammer on the top centre until the stop lever is pulled
down and the dog lever is set free, in order to raise the hammer again, the
hammer being constantly raised by the ratchet wheel moving the shaft round,

page_text: the hammer falling by its own weight as long as the stop lever N is held down.
This stop lever is provided with a spring N¹, over which the end of the dog
lever passes, the end of the lever then resting between the spring and the stop
on tho stop lever N. The other end of the boss to which the ratchet wheel is
secured is provided with a pulley, which is driven by a belt from another
pulley, or from a drum moved by hand or by power. Sometimes, instead of
using a pulley on the end of the boss when a heavy hammer is to be lifted, I
place a large toothed wheel O, which gears into a smaller wheel P on an addi-
tional shaft P', working on bearings on the frame I', on which also is keyed a
larger toothed wheel P2, gearing into a smaller wheel on a boss revolving
loosely on the first-mentioned shaft I, which said boss is provided with a
pulley R for a belt, moved as above described.
Having now described the nature of the said Invention, and in what manner
the same may be performed, I declare that I claim the arrangement and com-
bination of parts constituting the improved machinery or apparatus herein-
before described.
In witness whereof, I, the said Sam Hague, have hereunto set my hand
and seal, this Twenty-sixth day of August, in the year of our Lord One
thousand eight hundred and sixty-two.
