Improvements in Hydraulic Air Compressing Apparatus.
I, CHARLES HAVELOCK TAYLOR, of No. 57, Clandeboye Avenue, Westmount, near the
and Province of Quebec,
City of Montreal, in the District of Montreal
Dominion of Canada, Mechanical Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to apparatus of the type described in my Specification of
Patent No. 11,942 of 1894, and has for its object to improve the construction of such

page_text: apparatus whereby a thorough control and regulation of the flow of water and intake
of air can be secured.
The invention embodies as novel features, first, the use of a movable receiving end
for the vertical stand pipe adapted to act as a gate for controlling the flow of the
water, secondly, the arranging at the receiving end of a series of air inlets and a
common cut off device for regulating the quantity of air to be introduced; thirdly, in
the tapered form of the vertical stand pipe for maintaining a uniform speed of travel
of the water, fourthly, in the expansion of the lower end of the stand pipe for the
purpose of increasing the speed of flow of the descending body of water, fifthly,
in a spreader located beneath the lower end of the stand pipe for facilitating the
Beparation of the air from the water, and sixthly, in the stand pipe having a number
of projections formed on its interior to interfere with any tendency of the water to
whirl and form a central vortical cavity.
And in order that my invention may be clearly understood and readily carried into
effect. I will describe the same with reference to the accompanying drawings, in which
like symbols indicate corresponding parts and wherein Figure 1 is a vertical sectional
view of a preferable embodiment of my improved apparatus.
Fig. 2 is an enlarged horizontal section of same on line X X Fig. 1.

Fig. 4 is a horizontal sectional view thereof taken on line 4, 4 Fig. 3.
Fig. 5 is a similar view taken on line 5, 5, Fig. 3.
Fig. 6 is a detail plan view of a modification of the top portions of my stand pipe,
and
Fig. 7 is a transverse vertical sectional view thereof taken on line 7, 7, Fig. 6.
I will first describe the preferred embodiment of my invention as shown in
Figures 1 and 2.
a is the stand pipe or conductor sunk in a well as formerly and extending, from
the timbers of the usual dam formed about the opening of the well, to a cylindrical
base or dome b resting on the bottom of the well and through the top of which the
stand pipe passes. The lower end of the stand pipe reaches to about the centre of
the height of the dome.
To properly direct the water to the stand pipe a and to control and regulate the
flow and extent of head thereof, I use a movable or adjustable receiving end or
mouth piece preferably constructed as follows:-
A short length of cylinder c with a flared mouth c forms the mouth piece proper,
the lower end of the cylinder being adapted to enter and work within the upper end
of the stand pipe, and this mouth piece is formed with radial lugs c² through which
it is connected by bolts with a movable supporting frame comprising a disc d and
radiating arms d¹ through which disc and the ends of such aruns the bolts c³ pass.
The movable supporting frame is carried and operated by means of a screw e having
its bearing in an upper cross timber of the dam.
A regulating or cut off device in the form of au inverted cone f is located between
the supporting frame d d and the mouth piece, being supported by adjusting
screws fi, f¹, each of which carries a sprocket wheel / and the one being provided
with an extended stem and a hand wheel whereby through a connecting drive chain f
taken over the sprocket wheels the three screws can be simultaneously rotated and
so raise or lower the couef relatively to the mouth piece in order to increase or
diminish the inflowing head of water.
The necessary air ducts are in this case shown as a number of vertical tubes g
carried by and passing through the disc d of the movable supporting frame and each
having a series of nozzles g' directed towards the space between the mouth piece and
the regulating or cut off device which latter in its adjustinent up or down also serves
to regulate the quantity of air admitted by cutting off one or more of the series of
nozzles g¹.
The stand pipe a is preferably tapered gradually toward a point just above the
come b, or expansion chamber as it might be called, for the purpose of maintaining
a uniform speed of travel of the descending body of water while the portion a²

page_text: extending into the expansion chamber is gradually expanded towards its end for the
purpose of increasing the speed of flow above that point of the descending body of
water, the expansion of the end of the pipe having the effect of increasing the speed
of flow of the upper body of water.
Situated beneath the lower end of the stand pipe and supported preferably by a
base of masonry h is a spreader ; somewhat of saucer form in oross section but with a
central conical upward projection which meeting the falling body of water has
the effect of spraying it, thus liberating more effectively the air bubbles carried
by it.
The air when separated, passes up the conductor m to the usual tank or receiver
in the customary manner and the water is preferably allowed to travel through
ports n at the base of the dome b and pass from the wall at the top as formerly.
The construction just described although the most preferable can be modified in
several respects within the scope of my invention, and I will now describe what I
consider the chief and proferable modification, reference boing had to Figures 3, 4
and 5, wherein :-
a is the stand pipe or conductor, which in this instance I prefer not to taper, it is
sunk in a well as formerly and extends from the timbers of the usual dam formed
about the opening of the well downwards to a point midway of the height of an
expansion chamber or dome b which is located at the bottom of the wall and has an
opening b in its side with which the lower end of the stand pipe communicates,
such lower end being cut away obliquely, and flattened to allow of rivetting to such
dome.
The lower end of the pipe is connected with the side of the dome, in such a way
as to deliver the water tangentially into the dome and by so doing cause it to circle
round same and so create a whirlpool which has the effect of thoroughly separating
the air from the water;
To control the flow of water into the stand pipe, a, I use a movable or adjustable
receiving end of a construction that will have the effect of dividing the body of
water into a number of streams preferably converging toward a central point, with
the result that a greater quantity of air is drawn in and a solid body or column
without any central vortical cavity is formed in the stand pipe, which is not the case
where the inflowing body of water simply falls inwardly over the upper edge of the
stand pipe.
This preferred form of receiver is constructed, of a short length of cylinder c with
outer flared mouth piece c', which latter has a portion cat. out of its side, and an
inner mouthpiece located centrally of the outer mouth piece, and preferably con-
structed of a hollow cone c³ also having a corresponding portion cut out of its side,
and connected to the outer mouth piece by strips ct so that in addition to the annular
opening or inlet d between the outer and inner month pieces on the top of the
receiver there is also a side inlet d' leading to the inside mouth piece or cone c'.
This inner mouth piece acting with the outer one naturally has the effect of causing
the body of water to enter the stand pipe in two separate et reams and at the same
time the inner mouth piece tends to guide or direct one body thereof toward the
centre of the stand pipe since water passing through the side inlet d' must overflow
the edge of the inner mouth piece and will then follow, the outer surface thereof,
which converging as it does to a central point, will guide it to the centre.
A further modification of the receiver consists (as shown in Figures 6 and 7) in
constructing such receiver with a series of side inlets e and top inlets the sides g
of eich converging centrally so as to concentrate the body of water in the stand
pipe.
The movable receiver is supported and rendered adjustable by means of a screw h
passing through an upper cross timber of the dain, the lower end of the screw being
divided into arms h¹ connected to the inner mouth piece c'.
The air ducts are in the form of an annular series of vertical tubes, the lower
ends of which are located opposite the upper inlet of the receiver, being carried by a
disc which is provided at its centre with a screw threaded collar m adapted to work

page_text: on the screw in order to adjust the ends of the tubes nearer to or farther from the
water inlet, thus having the effect of diminishing or increasing the quantity of air
drawn in, a suitable handle m¹ being provided on the collar whereby it can be
rotated.
The air when separated passes up the conductor n to the usual tank in the
qustomary manner, and the water is preferably allowed to travel through ports p at
the base of the dome b and pass from the well at the top as formerly.
