I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby, declare the.
nature of the said Invention for "IMPROVEMENTS IN DOUBLE-ACTING LIFT
AND FORCE PUMPS," a communication, to be as follows:-

with the delivery pipe and check valve, the piston rods passing through
stuffing boxes at the top of the waterway and connecting by slots and
friction rollers with the brake or lever. The said rollers enter yoke
pieces formed at the ends of the piston rods. By this arrangement the
pump can be attached to the floor in some otherwise useless corner and
be out of the way, but at the same time very easily operated, and the
parts are not likely to get out of repair, and will be easily accessible for
keeping in order. I am aware that pumps have been made with an air
vessel that forms the fulcrum for the lever, but the arrangement of the
interior portions of such pumps are different from mine, and the lever is
connected to the piston rod by links. In my pump the said rollers and
yoke pieces enable me to obtain a very free movement in a less space
than heretofore; hence the said pump is very compact and can be
worked in a space that would be insufficient for other pumps of the same

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 14th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert, Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert Lake,
my executors, administrators, and assigns, should at any time agree with,
and no othiers, 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 DOUBLE-ACTING LIFT AND FORCE PUMPS," a communication to me from
abroad by William D. Baxter, of the City and State of New York,
United States of America, upon the condition (amongst others) that I,
the said William Robert Lake, 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 same was to be performed, and cause

page_text: 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 William Robert Lake, 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:-
In the accompanying Drawing forming a part of this Specification
Figure 1 represents a vertical sectional view of a pump embodying my
Invention; Figure 2 represents a section through line x, x, Figure 1.
:
Figure 3 represents a detached sectional view of the journal joint.
Figure 4 represents a detached side view of the fixed journal box
bed, male dovetail, and threaded bar.
Figure 5 represents a detached side view of the movable journal box.
The first part of the said Invention consists in arranging the air vessel
over and between the two pumps to form the fulcrum for the lever in
combination with a waterway connecting the open ends of the pumps
with the delivery pipe and check valve, the piston rods passing through
stuffing boxes at the top of the waterway and connecting by slots and
friction rollers with the brake or lever. The said rollers enter yoke
pieces formed at the ends of the piston rods. By this arrangement the
pump can be attached to the floor in some otherwise useless corner and
out of the way, but at the same time very casily operated, and the parts
are not liable to get out of repair, and will be easily accessible for keeping
in order.
a is a base to be bolted to a floor or platform; 6 is the inlet water:
pipe c, c, are the induction valves to the cylinders d, d, in which are
the pistons or valves e, e; fis a cap over the top of the cylinders d, d,
forming a waterway that terminates in the eduction pipe g with a check
valve, and this waterway f¹ rises and forms the air vessel k and also
receives the fulcrum i of the lever that is worked by the removable
lever or brake m provided with a socket setting over a square on 7. The
piston rods n pass through the stuffing boxes m¹ that guide and sustain
them while being operated by the rollers o, o, in jaws formed by the
lever 7, said rollers entering yoke pieces p that are formed at the ends of
the piston rod n,

page_text: It will now be understood that this pump is very compact, casily
applied to or removed from the pipes, can be set into a small compass,
and can be easily worked and kept in order.
I am aware that pumps have been made with an air vessel that forms
the fulcrum for the lever, but the arrangements of the interior portions.
of such pumps are different from mine, and the lever is connected to the:
piston rod by links. In my pump the said rollers and yoke pieces
enable me to obtain a very free movement in a smaller space than here-
tofore;
hence the said pump is very compact and can bo worked in a
space that would be insufficient for other pumps of the same capacity.
The second part of the said Invention is designed to prevent destruction
of the pumps and the great inconvenience and damage by water resulting.
from inability to sufficiently empty the pump of the water to prevent
the bursting of the cylinders in cold weather. In order to overcome;
these difficulties I make use of a double-acting cock placed between the
two cylinders, I am thereby enabled to empty the water out of the upper
part and out of the cylinders down into the reservoir and outlet pipe below
with one movement of the cock without having to empty the pump of
the water by separate cocks and separate vessels for carrying off the
water.
In the Drawing a is the base; b, the inlet water pipe which is placed
at the bottom or side of the reservoir R in order to cause the water to
run out of R, and also for placing the double-acting cock C and the
pipes or channels A, B, D, and E between the cylinders d, d...F. is the
cock cylinder into which the channels or pipes A, B, D, and E lead.
In this, cylinder is placed the cock C with a handle H, the former is
made hollow with four openings I, J, K, and L which are made to
correspond with the holes in the pipes or channels A, B, D, and E. By
ceasing to pump one of the piston valves e is left at the bottom of one
of the cylinders d, while the other valve e is left at the top of the
cylinder d by placing the lever in a slanting position. By placing the
handle H of the cock C parallel with the inlet pipe 6 the openings in
the cock barrel I, J, K, and L come opposite the openings A, B, D,
and E by which the water in the upper part is made to flow down into
the lower part or reservoir R from which it is emptied into the inlet
water pipe b. By turning the handle H of the cock C to the right or

page_text: Teft the openings A, B, D, and E are shut off by the cock C and the
pump is worked as ordinarily.
The third part of my Invention is designed to provide a jointed double
journal box or bearing for the axle of the pump. By the constant
friction on the sides of the journal boxes in which the axle works, as well
as of the sides of the chuck holding the axle, the metal wears away and
spaces are left between the said chuck and the sides of the journal boxes
by which the accurate motion of the arms or levers working the pistons
is impaired. I cast the journal boxes separately instead of together, and
in such a manner that one of the said boxes only is cast in one piece
with the bed which is provided with a female dovetail on the opposite
side and lengthened into a threaded screw in order to receive the male
dovetail in the loose journal box and a nut which holds the said dovetail
firmly to the bed. When the sides of the chuck and the journal boxes
are worn or reduced it is only necessary to take off the nut and the
female dovetailed journal box and remove by filing so much of the
shoulders of the part of the bed from which the male dovetail extends
as the metal worn away from the sides in order to insure at all times a
steady and accurate bearing.
In the Drawing A' as the chuck holding the axle B'; C¹ is the bed of
the journal box D'; E' is the male dovetail extending from the bed C¹;
F is the threaded round bar extending from the male dovetail E'; G¹ is
a nut fitting the threaded bar F¹; 9, 9, are shoulders of the male dove-
tale E'; H¹ is the journal box with a female dovetail I' in the lower end.
fitted to receive the male dovetail E¹.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
:
First. The pistons e and yoke pieces p actuated by the rollers o and
lever in combination with the pump cylinders d, d, and waterway f¹
provided with stuffing boxes for the piston rod n and an air vessel
parts being arranged and constructed substantially as specified.
Second. The double-acting hollow cock C with openings I, J, K,
and L, cylinder F with pipes or channels A, B, D, and E in combination
with the pump cylinders d, d, reservoir R, and inlet pipe b, substantially
as and for the purpose herein set forth.

page_text: Third. The dovetails E¹ and I', threaded bar F¹ and nut G¹ in com-
bination with the journal boxes D' and H' and the bed C³, substantially
as and for the purpose herein set forth.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and scal, this Fourteenth day of October,
in the year of our Lord One thousand eight hundred and seventy-
four.
