Year: 1862

page_text: LETTERS PATENT to John Barbour, of Liverpool, in the County of
Lancaster, Merchant, for the Invention of "IMPROVEMENTS APPLICABLE TO
UPHOLSTERERS' AND OTHER HAND HAMMERS."-A communication from
abroad by William Thomson, of the Firm of Thomson and Burns, of
the City of Toronto, in Canada.
Sealed the 10th October 1862, and dated the 16th April 1862.
PROVISIONAL SPECIFICATION left by the said John Barbour at the
Office of the Commissioners of Patents, with his Petition, on the 16th
April 1862.
I, JOHN BARBOUR, of Liverpool, in the County of Lancaster, Merchant,
5 do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO UPHOLSTERERS' AND OTHER HAND HAMMERS," to be as follows (that
is to say):-
This Invention consists in magnetising or applying magnetism in connection.
with hammers, that tacks or nails may be picked up by them and driven into
the wood or other substance.
These improved hammers it is preferred to construct with T-heads, and the
attraction end formed with a small face, and surrounded with a collar of gutta
percha or other suitable non-conducting substance to prevent the tacks or
nails adhering otherwise than to the magnetized face of the hammer, which

page_text: is presented to the head of the tack or nail to be picked up, that the point
may be presented to and inserted into the material into which it is to be
driven with great facility, when it can be driven home by the reverse end of
the hammer. The whole of the hammer head, except the two faces, is coated or
covered with a suitable non-conducting material. It is also proposed to fit the
bottom of the hammer helve with a pair of claws for the convenience of taking
out tacks or nails.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Barbour in the Great Seal Patent Office on the
16th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BARBOUR, of Liverpool, in the County of Lancaster, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, 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 John Barbour, Her special licence, that I, the said John Barbour,
my executors, administrators, and assigns, or such others as I, the said
John Barbour, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 APPLICABLE TO UPHOLSTERERS' AND OTHER HAND HAMMERS," a commu-
nication to him from abroad by William Thomson, of the Firm of Thomson
and Burns, of the City of Toronto, in Canada, upon the-condition (amongst
others) that I, the said John Barbour, my executors or adminstrators, 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 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 John Barbour, do hereby declare the
nature of my 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 (that is to say):-

page_text: This Invention consists in magnetising or applying magnetism in connection
with hammers, that tacks or other nails may be picked up by them and driven
into the wood or other substance.
These improved hammers it is preferred to construct with T-heads, and the
attraction end formed with a small face, and surrounded with a. collar of gutta
percha or other suitable non-conducting substance to prevent the tacks or nails
adhering otherwise than to the magnetised face of the hammer, which is
presented to the head of the tack or nail to be picked up, that the point may
be presented to and inserted into the material into which it is to be driven
with great facility, when it can be driven home by the reverse end of the
hammer. The whole of the hammer head, except the two faces, is coated or
covered with a suitable non-conducting material. It is also preferred to fit
the bottom of the hammer helve with a pair of claws for the convenience of
taking out tacks or nails. The bammer heads may be magnetised by any of
the ordinary methods now used to magnetise the needles of mariners' com-
passes, as is well understood, or in any other convenient way.
That the practical application of the said Invention may be the more readily
seen and understood, I have hereunto annexed Drawings of one of the
improved magnetised hammers; like letters marked on the Drawings are used
to denote similar parts.
Figure 1 is a side view of one of the magnetised hammers suitable for
driving tacks or other flat-headed nails, shown with a tack attached to the face
thereof ready to be driven; Figure 2 is a longitudinal section of the head of
the same; and Figure 3 is plan of the attraction face of the hammer, scen
surrounded by a ring of brass, gutta percha, or other suitable non-conducting
material to prevent the nail adhering on to the side of the hammer head.
A, the head of the hammer, which is coated on the sides with varnish or
other suitable non-conducting substance, and the end used to pick up
nails is surrounded by B, a ring of brass, gutta percha, or other suitable non-
conductor to prevent the nails adhering to the side of the head of the hammer;
C, the hammer helve, which is fitted at the lower end with D, a claw, for
drawing nails or other purposes; E is a tack, seen adhering to the hammer
head.
Having now fully described and ascertained the nature of the said Invention,
and how I believe the same may be best carried into practical effect, I wish
it to be understood that I do not confine myself to any peculiar form of
hammer, as it will be readily seen, that they may be greatly varied in external
form without departing from the Invention; but what I do claim is, mag-
netising hand hammers, so as to enable them to be used to pick up tacks or

page_text: other nails, substantially and in the manner herein-before described and set
forth, or any mere modification of the same.
In witness whereof, I, the said John Barbour, have hereunto set my
band and affixed my seal, this Fifteenth day of October, in the year of
our Lord One thousand eight hundred and sixty-two.
Witness,
WILLIAM WALKER,
of 44, Castle Street,
Liverpool.
JOHN (L.S.) BARBOUR.
