Improvements in Lawn Sprinklers.
I, DENNIS ALMON HOYT of St. Cloud, in the County of Stearns, State of
Minnesota, United States of America, do hereby declare the nature of this
nvention to be as follows:-
My invention relates to portable sprinklers of that class known as "revolving"
sprinklers, in which the water issuing from the nozzle is uniformly distributed at
distance therefrom upon a large surface; and the objects of my invention are to
produce a sprinkler of attractive appearance in which the direction and force of
the current can be regulated.
One form of sprinkler according to my invention comprises a circular plate
provided with diverging sockets on the under side thereof to receive the respective
ends of lugs, which are of suitable length, and form therewith a tripod for the
support of the operating parts. In the centre of the plate and in one piece
therewith, or attached thereto, is a tubular boxing provided at its top, and, also,
at its bottom, with suitable well known means for connection with a hose coupling
in such manner as to permit the hose to revolve freely in its bearings upon said
plate, so as to prevent the hose from twisting. The upper coupling may form a
part of or be suitably attached to a rubber nozzle while the lower coupling may
form a part of or be attached to a flexible hose, through which the water is
conducted to the spraying apparatus.
At a suitable distance above the plate a flat ring is supported upon bent rods
which have their lower ends inserted in the plate and project and diverge upwardly
therefrom and have their upper ends inserted in the said ring. This latter ring
has a lateral extension which forms a bushing to receive a shaft which carries on
its outer end a water wheel of any suitable construction, and on its inner end a
pinion which is received in a groove in the top of the ring. The ring is also
provided with upwardly projecting lugs preferably three, each having a stud
which projects upwardly therefrom and upon which is mounted a roller. Upon
said rollers is placed a flat ring or hose carriage which has, adjacent to its
periphery, a series of pendant teeth adapted to mesh with the pinion and be rotated
thereby.
The nozzle may be adjustably connected with the rotary ring or hose carriage,
and secured in suitable relation to the spraying apparatus so as to direct the
stream against the vanes or paddles thereof by means of an upwardly bent wire
which has its ends secured upon diametrically opposite sides of said ring, and is
provided with a series of loops, in to any one of which the metal tip of the hose
nozzle can be inserted. The desired stream of water issuing from said tip may be
regulated by a cock. The said support for the hose nozzle may, of course, consist
simply of a perforated bar extending across the carriage, and secured thereto.
To revolve the water wheel, a small stream of water may be directed by a pipe
to a point preferably above the wheel, but nearly tangential thereto, so that in
escaping it will impinge against or fill the buckets or paddles of said wheel. The

page_text: lower end of the pipe is inserted within the tubular boxing and its upper end is
provided with a flow-regulating cock.
To break into spray the jet of water escaping from the tip of the nozzle a
sprayer is placed upon and secured to the rotary ring or hose carriage, by a
support the latter consisting preferably of wire bent to form eyes to receive the
ends of a shaft, to which are secured in any suitable manner a series of strips of
suitable material preferably consisting of wires, arranged thereon, parallel to each
other. The ends of the supporting wire may be inserted in perforations in the
top of the ring or hose carriage, or may have feet to clasp said ring. The middle
portion of the wire is bent to form a loop, preferably rectangular in form, within
which the sprayer can revolve under the impulse of a jet of water issuing from
the nozzle. A prop for the middle portion of the loop is obtained by twisting
together the wires constituting an extension of said loop or by securing to the
centre of said loop a rod or wire, having its lower end doubled over to enter and
be retained in one of the loops of the nozzle support or guide.
A modified form of sprayer consists simply of a series of vanes or paddles of
suitable material, preferably flat strips of wood or metal, journaled upon a vertical
shaft and arranged so as to rotate in a horizontal plane in the line of the stream
from the hose instead of in a vertical plane.
In a further modification of the sprayer, instead of having a wire sprayer
arranged to revolve in front of the jet from the nozzle, the arrangement of these
parts may be reversed, and the sprayer be retained in a stationary position while
the nozzle revolves therein, in which case the jet of water issuing from said nozzle
will be converted into spray by contact with the vanes or wires. In this case a
wire sprayer or deflector is placed upon and secured to the stationary ring of the
frame. Said deflector consists preferably of a series of wires forming a globular
structure but, of course, strips or vanes of metal or other suitable material may be
used instead of wire to form the sprayer.
The wires have their lower ends secured at any desired angle in a ring and their
upper ends are preferably connected to a suitable ring. The location of said
sprayer and of its lower end is such as not to interfere with the revolutions of the
cogged ring or of the nozzle therein, and the elasticity of the rubber nozzle
together with the loose bearing in the tripod frame permits it to revolve within
said ring without twisting the hose. In order to protect a path or walk, a house
or any other object, from the jet or spray of water during a portion of the rotation
of the nozzle, a sheet-metal shield, or deflector may be used, said shield being
removably secured to the stationary ring and the tripod frame being so located
as to have its shield toward the object to be protected. Said shield is preferably
constructed in the form of a segment of a cylinder, having its upper portion bent
inwardly to properly deflect the jet or spray of water downwardly. Said shield
may be used on the device in connection with the wire sprayer or independent
thereof if desired.

Improvements in Lawn Sprinklers.
I, DENNIS ALMON HOYT, of St. Cloud, in the County of Stearns, State of
Minnesota, United States of America, do hereby declare the nature of this inven- 50
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention relates to portable sprinklers of that class known as “revolving”

page_text: sprinklers, in which the water issuing from the nozzle is uniformly distributed at a
distance therefrom upon a large surface; and the objects of my invention are to
produce a sprinkler of attractive appearance in which the direction and force of
the current can be regulated. I attain these objects by the construction illustrated
in the drawings in which
Fig. 1 is a perspective view of a sprinkler constructed in accordance with my
invention showing a pivoted rotatory sprayer thereon;
Fig. 2 is a side elevation of the same, showing a modification of the spraying
apparatus;
Fig. 3 is a transverse vertical section of a portion of the last mentioned sprayer
illustrating its construction;
Fig. 4 is a transverse vertical section of a portion of the device showing a spray
deflector plate attached thereto;
Fig. 5, is a detail representing a modification of the pivoted rotatory sprayer.
In the drawings, A represents a circular plate provided with diverging sockets a
on the under side thereof to receive the respective ends of the lugs B, which are of
suitable length, and form therewith a tripod for the support of the operating parts.
In the centre of the plate A, and in one piece therewith, or attached thereto is a
tubular boxing provided at its top, and also, at its bottom, with suitable well known
means for connection with a hose coupling in such manner as to permit the hose to
revolve freely in its bearings upon said plate, so as to prevent the hose from
twisting. The upper coupling d, may form a part of or be suitably attached to a
rubber nozzle D, while the lower coupling d, may form a part of or be attached to
a flexible hose C, through which the water is conducted to the spraying apparatus.
At a suitable distance above the plate A, a flat ring E, is supported upon bent
rods e which have their lower ends inserted in the plate A, and project and diverge
upwardly therefrom and have their upper ends inserted in the said ring E. This
latter ring has a lateral extension which forms a bushing B³, to receive a shaft f
which carries on its outer end a water wheel F, of any suitable construction, and on
its inner end a pinion f³, which is received in a groove in the top of the ring E.
The said ring is also provided with upwardly projecting lugs e³, preferably three,
each having a stud which projects upwardly therefrom and upon which is mounted
a roller e. Upon said rollers is placed a flat ring or hose carriage G, which has,
adjacent to its periphery, a series of pendant teeth adapted to mesh with the
pinion and be rotated thereby.
The nozzle D, may be adjustably connected with the rotary ring or hose
carriage G, and secured in suitable relation to the spraying apparatus so as to
direct the stream against the vanes or paddles thereof by means of an upwardly
bent wire g, which has its ends secured upon diametrically opposite sides of said
ring, and is provided with a series of loops g³, in to any one of which the metal
tip D' of the hose nozzle can be inserted. The desired stream of water issuing from
said tip may be regulated by the cock d. The said support for the hose nozzle
may, of course, consist simply of a perforated bar extending across the carriage,
and secured thereto. To revolve the water wheel, a small stream of water may be
directed by the pipe k to a point preferably above the wheel F, but nearly
tangential thereto, so that in escaping it will impinge against or fill the buckets or
paddles of said wheel. The lower end of the pipe k is inserted within the tubular
boxing a, and its upper end is provided with a flow-regulating cock k².
To break into spray the jet of water escaping from the tip of the nozzle a
sprayer L is placed upon and secured to the rotary ring or hose carriage G, by its
support L³, the latter consisting preferably of wire bent to form eyes 1, to receive
the ends of the shaft, to which are secured in any suitable manner a series of
strips of suitable material preferably consisting of wires, arranged thereon, parallel
to each other. The ends of the supporting wire L', may be inserted in perforations
in the top of the ring or hose carriage G, or may have feet to clasp said ring.
The middle portion of the wire L³, is bent to form a loop l, preferably rectangular

page_text: in form, within which the sprayer can revolve under the impulse of a jet of water
issuing from the nozzle. A prop for the middle portion of the loop 1, is obtained
by twisting together the wires constituting an extension of said loop or by securing
to the centre of said loop a rod or wire 1, having its lower end doubled over to
enter and be retained in one of the loops g³, of the nozzle support or guide
The modified form of sprayer illustrated in Figure 5, consists simply of a series
of vanes or paddles of suitable material, preferably flat strips of wood or metal,
journalled upon a vertical shaft and arranged so as to rotate in an horizontal plane
in the line of the stream from the hose instead of in a vertical plane, as indicated in
Figure 1.
A further modification of the sprayer is illustrated in Fig. 2, in which, instead of
having a wire sprayer arranged to revolve in front of the jet from the nozzle, as
shown in Figs. 1 and 5, the arrangement of these parts may be reversed, and the
sprayer be retained in a stationary position while the nozzle revolves therein, as
indicated in Figure 2, in which case the jet of water issuing from said nozzle will
be converted into spray by contact with the vanes or wires. In this case a wire
sprayer or deflector M is placed upon and secured to the stationary ring E of the
frame. Said deflector consists preferably of a series of wires forming a globular
structure as indicated in Fig. 2, but, of course, strips or vanes of metal or other
suitable material may be used instead of wire to form the sprayer. As shown in
said Fig. 2 the wires m have their lower ends secured at any desired angle in a
ring m³, and their upper ends are preferably connected to a suitable ring as shown.
The location of said sprayer and of its lower end is such as not to interfere with the
revolutions of the cogged ring E, or of the nozzle therein, and the elasticity of the
rubber nozzle together with the loose bearing in the tripod frame permits it to
revolve within said ring without twisting the hose. In order to protect a path or
walk, a house or any other object, from the jet or spray of water during a portion
of the rotation of the nozzle, a sheet metal shield, or deflector n may be used, said
shield being removably secured to the stationary ring E and the tripod frame being
so located as to have its shield toward the object to be protected. Said shield is
preferably constructed in the form of a segment of a cylinder, having its upper
portion bent inwardly at n to properly deflect the jet or spray of water downwardly.
Said shield may be used on the device in connection with the wire sprayer or
independent thereof if desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. In a lawn sprinkler the combination of the stand, the rotating carriage, the
