Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTUST
COFFYN, of Paris, in the Kingdom of France, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of March, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Augustus Coffyn, Her especial licence, full power, sole privilege and authority,
that I, the said Augustus Coffyn, my exors, admors, and assigns, or such
others as I, the said Augustus Coffyn, my exors, adñiors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should' and lawfully might make,
usc, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN PUMPS;" in which said
Letters Patent is contained a proviso, that I, the said Augustus Coffyn, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Augustus Coffyn, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference.
being had to the Drawing hereunto annexed, and to the figures and letters
marked thereon (that is to say):-

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 represents a longitudinal section of a pump constructed according
to the Invention; and Figure 2 shews another arrangement applied on Figures
1, 3, 4, and 5. A is the body of the pump, having projections 6 therefrom, by
which means it may be securely affixed to any required place; the piece of
wood to which it is affixed is shewn at B. Around the upper part of the body
of the pump is formed a flange c, to which the packing e is secured, the edge
of such packing lying in the recess d. In the internal part of the body of the
pump A is formed an irregular surface D; this irregular surface is con-
nected to the body of the pump, so that it may be adjusted as required. The
surface D may be formed into either three, four, or more double inclined
planes, according to the size of the pump. The tube E is affixed to the lower
part of the body of the pump, and may be composed of one or more. pieces
F is a valve attached to the pump, which cowers the opening from the pipe
E into the body of the pump; G is the metallic piston, according to my Inven
tion, which slides in the body of the pump; the lower edge of this piston is
similarly irregular on its surface to the surface D. The edge of the piston G
carries small rollers h, which rest upon the uneven or irregular surface D. The
pistón G is kept hermetically closed in the body of the pump by means of the
packing e. There is an opening at the upper part of the piston G communi
cating with the tube I, through which the water pumped up is forced. J is a
valve affixed over this opening. To the upper part of the piston G are affixed
sockets K to receive bars or levers L, the moving of which levers laterally will
give a rotatory motion to the piston G, and consequently will cause it to
ascend or descend, according to the depth of the undulations on the surface
D, thus will the water be raised and forced away as may be required. It is
necessary, when first employing this pump for the purpose of raising water
that a small quantity of water should be placed in the body of the pump; to de
this it will be necessary to unscrew and withdraw the bolt m, and place therein
by any suitable means a small quantity of water, and afterward screwing up
the bolt, when it will be found to work effectually; when the water is required
to be forced up some little height, it will be found advantageous to weight the
upper part of the piston G. Figure 3 shews a plan of the upper part of the
piston, with the sockets k, through which the bars or levers are passed when th
pump is required to be worked. Fig. 4 and 5 are horizontal sections, mad
according to the line 1, 2, of Figure 1. Figure 4 is a plan of the under sid

page_text: of the piston G, shewing the small rollers. Figure 5 shews a sectional plan of
the body of the pump A, through the lines 1 and 2, shewing the irregular sur-
face D: The body of the pump A may receive the rotatory movement instead
of the piston G, and reciprocally. Figures 2 and 6 shew another arrangement
of the Invention, where the irregular surface is placed separate from the body
of the pump, and so as to operate upon the piston rod in such manner as to
give an up-and-down motion to the piston, instead of being in the interior of
the body of the pump. In this arrangement the barrel, piston, and valves are
similar to those parts of pumps ordinarily in use, the irregular surface or way
being in connection with the piston rod, so that a rotatory and rectilinear
movement may be given to it. A¹ is the body of the pump; having two
openings to admit the water, and two openings for forcing it through; B¹ is a
piston packed with suitable packing. The piston rod is brought up through
the upper part of the pump, so as to be in direct communication with the
handles or levers D¹, which give motion to it. On the piston rod C¹ is formed
a cross piece E¹, form of which is shewn more clearly in the Drawing at
Figure 6. The number of arms to the cross piece will depend upon the size
of the pump; at the end of each of these arms there is a guide roller h¹. G¹is
the undulated or irregular surface on which the rollers h¹ rest; over this
irregular surface G¹ is formed a corresponding irregular surface I',bywhich
the rollers are controled to follow the undulations of the surface G¹, when
by pushing or drawing the levers D' a rotatory motion is given to the piston
rod C, and by the undulated surface the piston is caused to ascend or
descend. This latter arrangement may be applied to any ordinary pump.
Having thus described the nature of the Invention, and the manner of per-
forming the same, I would have it understood that I do not confine myself to
the precise details herein described, so long as the character of the Invention
be retained; but what I claim is, the mode of giving a rotary and rectilinear
motion to the piston of pumps, as herein described.
In witness whereof, I have hereunto set my hand and seal, on this
Twentieth day of August, in the year of our Lord One thousand eight
AUGUSTE (L.S.) COFFYN.
