Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME I, JACOB
TILTON SLADE, of Carburton Street, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, did, by Her
Letters Patent under the Great Seal of that part of the United Kingdom of
Great Britain and Ireland called England, bearing date at Westminster, the
Third day of November, in the second year of Her reign, give and grant unto
me, the said Jacob Tilton Slade, my executors, administrators, and assigns,
Her especial licence, full power, sole privilege and authority, that I, the said
Jacob Tilton Slade, my executors, administrators, and assigns, and such others'
as I, the said Jacob Tilton Slade, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all times
hereafter during the term of years therein mentioned, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, and also in all Her Colonies and Plantations abroad,
my Invention of "CERTAIN IMPROVEMENTS IN PUMPS POR LIQUIDS OR AERIFORM
FLUIDS;" in which said Letters Patent there is contained a proviso, that I, the
said Jacob Tilton Slade, shall cause a particular description of the nature of
my said Invention, and the manner in which the same is to be performed by
an instrument in writing under my hand and seal, to be inrolled in Her
Majesty's Court of Chancery within six calendar monthis next immediately
after the date of the said in part recited Letters Patent; reference being
thereunto had, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Jacob Tilton Slade, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be known and performed, are par-
ticularly described and ascertained in and by the following description thereof,
reference being had to the Drawings hereunto annexed, and to the letters and
figures marked thereon.
My Invention consists of a leather or other flexible barrelled pump, outside
of which a conical, cylindrical, or speroidal wheel, or a scraper, or a rubber, is
made to act in such manner that the fluids within the pump, whether they be
of a fixed or of an elastic character, are impelled or moved in the required
direction. Fig. 1 in the Drawing exhibits a leather or other flexible barrel or
chamber (at A, A), laid or fixed in a circular position. Into this barrel the
water or other fluid flows (at B). The flexible barrel is thus distended by the
water, and when the conical wheel or runner C is forced round in its course,
(D being its axis or pivot, and E being the handle where the power is applied),
the wheel runs upon the distended barrel, and by forcing that part of the barrel
which is immediately under it into a collapsed or contracted condition, the water
or other, liquid in the anterior portion of the barrel is forced onward, and
passes out by the pipe F, F¹: The runner wheel being kept in the required
continuous circular course round upon the flexible barrel, it will be seen that
the water or other liquid will always flow into that portion of the barrel
posterior to the runner wheel, and be forced forward from that portion of the
barrel which is anterior to the runner wheel. The flexible barrel in this
Figure, consists of two angular rings of leather, having their respective ends
elongated at B and F; the elongated ends when fixed together, as in Figure 1,
serve for the inlet and outlet, and the edges of the other parts of the leather
are sewed, rivetted, or nailed, or fixed together by rings G, G, or other suitable
contrivance. The whole is fixed in a wooden frame, of a suitable kind, and
forms an economical and effective pump. Figure 2 shews an elevation of the
same pump shewn in Figure 1, and the same parts on these two Figures are
distinguished by the same letters.
Sometimes I use a frame of wood, metal, or other suitable material, and
prepare a bed, as shewn in Figure 3, at H, H, and upon this bed I fix
my leather or other flexible material P, P, by means of rings, as shewn in
section at J, J, and the barrel in this case consists partly of the prepared
bed H, H, and partly of the leather or flexible material P, P. K is the
runner wheel; L, L, are the handles or levers; M, the axis or pivot; N, the
inlet, and the outlet is placed close beside the inlet, as will be seen by

page_text: reference to Figure 4, which exhibits a plan of Figure 3, without the runner
wheel and apparatus for working the same. O (Figure 4) shews the outlet;
Q, Figure 4, is a division between the inlet and outlet pipe.
Figure 5 is a section of another modification of a similar pump. R is the pipe
of leather or other flexible material, distended, on the one side and compressed
under the conical runner wheel S on the other side; T is the handle for giving
motion to the runner wheel S; U, U, are pins and screw nuts for securing the
leather or flexible pipe; W is the axis or pivot on which the handle and runner
wheel S turns; X is a screw or screws for raising or lowering, and for adjusting
the amount of pressure on the pipe R.
Figure 6 is a section of another modification of my improvements, applied
as a bellows for producing a blast of air, and which may also be used for
liquids. b, b, is a pipe, formed by sewing, rivetting, or otherwise fastening
together the edges of two circular rings of leather or other flexible material;
parts of the upper and lower surfaces are gripped tight underneath two
metal rings Y, Y. These rings Y, Y, are fixed by screws Z, Z.
a, a, is. a
plate, of wood, metal, or other suitable substance, the sides or rims being
dished or sloped at an angle. This plate I use between my runner
wheel C and the flexible pump barrel or tube. As the runner wheel C
revolves on a, a, this plate a, a, is depressed under it, and by its conical shape
expands the flexible pump barrel under the opposite edge of the plate. The
alternate elevation and depression of the conoidal plate a, a, by the revolution
of the roller wheel c, produces in the flexible pump barrel or tube between the
conoidal plate and the bed or frame e, e, an alternate expansion and contraction,
by which action I can pump elastic fluids.
Figure 7 is an elevation of another modification of my Invention. Here I
employ more than one runner wheel, and the flexible pump barrel or tube
forms only part of a circle or other curve, and the runner wheels only press
upon the flexible barrel during a part of their revolution round the centre f.
9, 9, 9, 9, are the runner wheels; h, h, is the flexible barrel or tube; j, the
in'et; and k, the outlet.
I have now described my improvements in pumps for liquids or acriform
fluids, with reference to the annexed Drawings, in such manner as to enable
persons conversant with works of a similar nature to. practice the Invention;
and I claim as my Invention, the flexible or partly flexible pump barrel or
pipe, the fluid therein being acted upon by a roller, wheel, rubber, or scraper,
externally applied thereto, for the purpose of compressing the said flexible or
partly flexible pump barrel or tube, and I do not limit my claim to the precise

page_text: forms shewn in the Drawings hereunto annexed. And I claim this kind of
pump as my Invention, whatever be the suitable material or materials of which
it may be found most convenient and useful to construct the same, and whether
the action of the compresser be in a curvilinear or. rectilinear line or lines.
And I claim to maintain exclusive right and privilege to my said Invention,
both as a pump and as a meter.
In witness whereof, I, the said Jacob Tilton Slade, have hereunto set my
hand and seal, this Third day of May, in the year of our Lord One
thousand eight hundred and thirty-nine.
