Year: 1875

page_text: LETTERS PATENT to Mark Amos, of Westbury-upon-Trym, in the
County of Gloucester, Blacksmith, for the Invention of "IMPROVE-
MENTS IN TOOLS FOR DIVIDING LONGITUDINALLY THE END OF A BAR OF IRON
OR OTHER METAL.”
Sealed the 9th May 1876, and dated the 16th November 1875.
PROVISIONAL SPECIFICATION left by the said Mark Amos at the:
Office of the Commissioners of Patents, with his Petition, on the
16th November 1875.
I, MARK AMOS, of Westbury-upon-Trym, in the County of Gloucester,
Blacksmith, do hereby declare the nature of the said Invention for _
"IMPROVEMENTS IN TOOLS FOR DIVIDING LONGITUDINALLY THE END OF A BAR OF
IRON OR OTHER METAL," to be as follows:-
This Invention has for its object to construct a tool by which the ends;
of bars of iron or other metal may with great rapidity be divided longi- .
tudinally. For this purpose I construct a tool in the manner, shown in ;
the Drawing hereunto annexed. This tool consists of a bed A which:
can be fixed on an anvil or in other convenient positions. Above one
1

page_text: end of the bed is a projection B; C is a hole corresponding with the
section of the bar to be cut, and formed equally through the projection
B and end of bed A; C¹ is a groove or recess in the upper surface of the
bed A, in continuation of the lower half of the hole C; D is a shear
blade pin jointed at E to the bed A. The cutting edge D' of this blade
works against the upper surface of the bed, whilst the edge D² works.
against the end of the projection B. If the end of a bar of iron or other
metal be inserted through the hole C into the groove C³, and the blade
D be turned by the powerful lever handle D³, half of the end of the bar
will be at once sheared off, so bringing the end of the bar to the form
shewn at Figure 2.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Mark Amos in the Great Seal Patent Office on
the 16th May 1876.
&
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARK
AMOS, of Westbury-upon-Trym, in the County of Gloucester, Black-
smith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Mark Amos, Her special
license that I, the said Mark Amos, my executors, administrators,
and assigns, or such others as I, the said Mark Amos, my exe-
cutors, 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
"IMPROVEMENTS IN TOOLS FOR DIVIDING LONGITUDINALLY THE END OF A BAR, OF
IRON OR OTHER METAL," upon the condition (amongst others) that I, the
said Mark Amos, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to

page_text: 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 Mark Amos, 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, that is to say :—
This Invention has for its object to construct a tool by which the ends
of bars of iron or other metal may with great rapidity be divided longi-
tudinally. For this purpose I construct a tool in the manner shown in
the Drawing hereunto annexed. This tool, see Figures 1 & 2, consists.
of a bed A which can be fixed on an anvil or in other convenient
positions. Above one end of the bed is a projection B; C' is a hole corre-
sponding with the section of the bar to be cut, and formed equally
through the projection B and end of bed A; C¹ is a groove or recess in
the upper surface of the bed A, in continuation of the lower half of the
hole C; D is a shear blade pin jointed at E to the bed A. The cutting
edge D¹ of this blade works against the upper surface of the bed, whilst
the edge D² works against the end of the projection B. If the end of a
bar of iron or other metal be inserted through the hole C into the groove
C¹, and the blade D be turned by the powerful lever handle D³, half of
the end of the bar will be at once sheared off, so bringing the end of the
bar to the form shown at Figure 2.
The cutting edges of the shear blade D are formed of steel hardened
and tempered, whilst the 'bed A and projection B at its end I prefer to
form of iron, but it might be of other metal.
A modification of the tool above described adapted for dividing the
ends of bars of different sizes is shown at Figures 3 and 4; Figure 3
shows a side view, and Figure 4, a plan view of the tool.
A is a circular disc mounted upon an axis at A¹, this axis is carried
by the frame F; B is a rim formed partially around the edge of the disc
and projecting out from one of its sides; C' are grooves; in this side of
the disc they are of different dimensions and each corresponds to one
half of the section of one or other of the bars which the tool is adapted
for dividing; C are holes through the rim B, and which correspond with
the complete section of the bars; D is the shear blade corresponding to
the blade in the tool above described, it is free to turn upon the axis A¹;

page_text: E is a screw bolt screwed through the frame F to enter holes in the disc
A and lock it in any desired position. The end of the bar to be divided
is inserted through whichever of the holes. C corresponds with it; the
shear blade D is then turned by its lever handle D', and one half of the
end is cut away as with the tool first described.
The cutting blade D is shown to be formed separately from its lever
handle D; it fits into a recess in the end of the lever handle and is
secured by a bolt G.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that I claim, the 1
construction of tools, substantially as herein described for dividing:
longitudinally the end of a bar of iron or other metal.
In witness whereof, I, the said Mark Amos, have hereunto set
my hand and seal, this Thirteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-six.
