Devon, Currier, for the Invention of "PUMPS WITH A NEW OR IMPROVED
BOX AND VALVE."
Sealed the 12th September 1856, and dated the 17th March 1856.
PROVISIONAL SPECIFICATION left by the said Thomas Palmer at the
Office of the Commissioners of Patents, with his Petition, on the 17th
March 1856.
I, THOMAS PALMER, do hereby declare the nature of the said Invention for
"PUMPS WITH A NEW OR IMPROVED BOX AND VALVE," to be as follows:-
On a centre spindle or main rod are attached brackets and annuli holding
rings, or layers of leather, or other suitable material. On this centre spindle
the valve works. This valve may be tapered off so as to press out the leather
(or material substituted for it) as it becomes worn, although it might even be
rounded instead of tapered off.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
PALMER, of Tavistock, in the County of Devon, Currier, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Palmer, Her special licence that I, the said Thomas Palmer, my
executors, administrators, and assigns, or such others as I, the said Thomas
Palmer, 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 "PUMPS WITH A NEW OR IMPROVED"
Box AND VALVE," upon the condition (amongst others) that I, the said Thomas
Palmer, 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 sanie
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 Thomas Palmer, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
the following
formed, to be particularly described and ascertained in and
statement:-
The nature of the said Invention, as hath been before set forth in the
Provisional Specification, left and recorded on application for the said Letters
Patent, consists in this, viz., I construct pumps by attaching to the centre
spindle or main rod thereof brackets and annuli holding rings, or layers of
leather, or other suitable material (that is, material resembling leather as
On this centre
regards pliability, toughness, and subsistence in water).
spindle the valve works. This valve may be tapered off so as to press out
the leather (or material substituted for it) as it becomes worn, although it
might even be rounded instead of tapered off.
Having thus far described my said Invention, I now proceed further to
describe the same, and in what manner the same is to be performed, wherein

page_text: I shall refer to the accompanying Drawings by the words, figures, and letters
marked thereon and hereafter set forth.
DESCRIPTION OF THE DRAWING.
The said Drawing exhibits the Invention by several views, marked Fig. 1
to Fig. 5 inclusive. In Fig. 1, which is a perspective view, A denotes the
centre spindle or main rod of the pump; B, leather rings in flat layers.
(Instead of several layers one layer or two layers might be adopted, though
I do not recommend this). C, upper brackets to hold the leather; C¹, lower
brackets for the same purpose, the leather rings being fitted between the
annuli D and D, attached to the brackets C and C respectively; E, valve
(here shewn open) which works or slides up and down on the centre spindle
aforesaid; F and F are screw nuts to keep the brackets and annuli in proper
position. In Fig. 2 a plan view is given; sometimes (as shewn at Fig. 3)
vertical section. Fig. 4 (top plan of pump box), and Fig. 5 (bottom plan of
pump box). I dispense with the parts marked C and C', and maintain the
leather (B) and box in its place by the annuli D* at the bottom, which is
secured to the spindle A by a cross piece d, with an enlarged part and orifice
in the centre to take the spindle A, with wires or bolts (e) passing through
the layers of leather, and fastened to the said annuli D* at the bottom to keep
them from rising out of place. The parts the same as those in Figs. 1 and 2
are marked the same.
Having now particularly described the nature of the said Invention, and
in what manner the same is to be performed, I declare that I do not claim
the component parts of the mechanism or apparatus set forth and described
when separately considered; what I claim being the Invention for pumps
with the kind of box and valve, the nature and character whereof is set forth
in this my Specification thereof, including any colorable imitation thereof.
In witness whereof, I, the said Thomas Paliner, have hereunto set my
hand and seal, this Seventeenth day of September, in the year of our
Lord One thousand eight hundred and fifty-six.
Signed and sealed in my presence,
FR CAMPIN,
Patent Office, 156, Strand.
THOS. PALMER. (L.S.)
