BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a liquid link system and more particularly 
pertains to allowing the coupling of a hose to an existing sprinkler head. 
2. Description of the Prior Art 
The use of water handling devices of known designs and configurations is 
known in the prior art. More specifically, water handling devices of known 
designs and configurations heretofore devised and utilized for the purpose 
of coupling hoses to sources of water through known methods and 
apparatuses are known to consist basically of familiar, expected, and 
obvious structural configurations, notwithstanding the myriad of designs 
encompassed by the crowded prior art which has been developed for the 
fulfillment of countless objectives and requirements. 
By way of example, U.S. Pat. No. 5,292,071 to Kruer discloses an In-Ground 
Pull-Up Sprinkler With Above Ground Hose Connection. U.S. Pat. No. 
4,809,732 to Buehler discloses a Fitting For Cleaning Water From Fluid 
Containing Systems. U.S. Pat. No. 5,368,229 to Hayes et al. discloses an 
In Ground Pop-Up Sprinkler With Above Ground Hose Connection. U.S. Pat. 
No. 3,635,501 to Thorne-Thomsen discloses a Quick Connect-Disconnect Hose 
Coupling. U.S. Pat. No. 5,355,905 to Burgess et al. discloses an 
Underground Sprinkler System and Methods for Winterizing and Installing 
the Same. Lastly, U.S. Pat. No. 5,104,150 to Bard et al. discloses a 
Multiple Purpose Irrigation Fitting. 
While these devices fulfill their respective, particular objectives and 
requirements, the aforementioned patents do not describe liquid links as 
disclosed herein. 
In this respect, the liquid link according to the present invention 
substantially departs from the conventional concepts and designs of the 
prior art, and in doing so provides an apparatus primarily developed for 
the purpose of allowing the coupling of a hose to an existing sprinkler 
head. 
Therefore, it can be appreciated that there exists a continuing need for a 
new and improved liquid link which can be used for allowing the coupling 
of a hose to an existing sprinkler head. In this regard, the present 
invention substantially fulfills this need. 
SUMMARY OF THE INVENTION 
In view of the foregoing disadvantages inherent in the known types of water 
handling devices of known designs and configurations now present in the 
prior art, the present invention provides an improved liquid link system. 
As such, the general purpose of the present invention, which will be 
described subsequently in greater detail, is to provide a new and improved 
liquid link system and method which has all the advantages of the prior 
art and none of the disadvantages. 
To attain this, the present invention essentially comprises a new and 
improved liquid link system for allowing the releasable coupling of a hose 
to an existing sprinkler head. The system comprises, in combination a 
central body portion. The central body portion is in a generally 
cone-shaped configuration and has a flat upper surface and a flat lower 
surface and a water inlet recess. The water inlet recess extends upwardly 
from the lower surface to an intermediate location thereof. The water 
inlet recess has a small cylindrical aperture which extends upwardly from 
the recess to the upper surface of the cone-shaped member adapted to 
receive therein a pin from an existing sprinkler head with an upper end 
having male threads. Further included in the system is a pair of 
diametrically opposed blocks. The blocks are located on the exterior 
surface of the body portion for rigidity purposes. Each of the blocks have 
a generally cylindrical bore extending therethrough for coupling with the 
recess to exterior of the blocks. Additionally provided is a pair of 
threaded cylindrical members. The members extend radially outwardly from 
the blocks with apertures as extensions of the bores and with exterior 
male threads. One of the male threads being 3/4" in diameter and the other 
being 1" in diameter. A cap is removably positioned over each male thread. 
Each cap has either 3/4" or 1" primary female threads positioning 
thereover and for removal to allow coupling by the inlet end of a hose. 
Each cap is further positionable on the top of the upper flat surface of 
the central body with secondary female threads for detachably coupling to 
the drive assemble post. Lastly provided in the system is an annular 
gasket. The annular gasket is positioned on the lower surface of the 
cone-shaped member around the recess for water sealment purposes when 
coupled to a sprinkler head. 
There has thus been outlined, rather broadly, the more important features 
of the invention in order that the detailed description thereof that 
follows may be better understood and in order that the present 
contribution to the art may be better appreciated. There are, of course, 
additional features of the invention that will be described hereinafter 
and which will form the subject matter of the claims appended hereto. 
In this respect, before explaining at least one embodiment of the invention

is then susceptible of low prices of sale to the consuming public, thereby 
making such liquid link system economically available to the buying 
public. 
Even still another object of the present invention is to provide a liquid 
link system for allowing the coupling of a hose to an existing sprinkler 
head. 
Lastly, it is an object of the present invention to provide a new and 
improved liquid link system including a central body portion having an 
upper surface and a lower surface and a water inlet recess extending

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIG. 1 thereof, 
the preferred embodiment of new and improved liquid link system embodying 
the principles and concepts of the present invention and generally 
designated by the reference numeral 10 will be described. 
The present invention, of the liquid link system 10 is comprised of a 
plurality of components. Such components in their broadest context include 
a central body portion, a pair of blocks, a threaded cylindrical member, 
cylindrical aperture and a threaded lid cap. Such components are 
individually configured and correlated with respect to each other so as to 
attain the desired objective. 
The new and improved liquid link system 10 for allowing the releasable 
coupling of a hose to an existing sprinkler head comprises, in combination 
a central body portion 14. The central body portion is in a generally 
cone-shaped configuration and has a flat upper surface 16 and a flat lower 
surface 18 and a water inlet recess 20. The water inlet recess extends 
upwardly from the lower surface to an intermediate location thereof. The 
water inlet recess has a small cylindrical aperture 22 which extends 
upwardly from the recess to the upper surface of the cone-shaped member 
adapted to receive therein a pin 24 from an existing sprinkler head with 
an upper end having male threads 26. 
Further included in the system is a pair of diametrically opposed blocks 
30. The blocks are located on the exterior surface of the body portion for 
rigidity purposes. Each of the blocks have a generally cylindrical bore 32 
extending therethrough for coupling with the recess to exterior of the 
blocks. 
Additionally provided is a pair of threaded cylindrical members 34, 36. The 
members extend radially outwardly from the blocks with apertures 35, 37 as 
extensions of the bores and with exterior male threads 38, 40. One of the 
male threads being 3/4" in diameter and the other being 1" in diameter. 
A cap 44 is removably positioned over each male thread 38, 40. Each cap has 
first female threads 46 for removable positioning thereover and for 
removal to allow coupling by the inlet end of a hose. Further, the cap is 
positionable on the top of the upper flat surface of the central body 
portion with second female threads 52 for detachably coupling to the 
threaded drive assembly post. 
Lastly provided in the system is an annular gasket 54. The annular gasket 
is positioned on the lower surface of the cone-shaped member around the 
recess for water sealment purposes when coupled to a sprinkler head. 
Golf courses, parks, farms and gardens that use underground sprinkler 
system usually have a few brass "quick couplers" which are used to connect 
to watering hoses to irrigate areas which the sprinklers do not reach. A 
problem arises wherein long lengths of hose are still needed to reach all 
those areas. This problem not only adds a large expense it is very time 
consuming when gardeners or maintenance workers have to drag these holes 
all over the place. While attempts have been made to connect hoses to the 
sprinkler heads themselves, they have been unsuccessful because the cap 
and nozzle assembly of existing sprinkler head is one unit. The drive fins 
on the drive assembly spin the entire cap and nozzle assembly 
counterclockwise to disperse water through the sprinkler nozzles. 
Therefore, it is impossible to adapt or connect any hose nozzles to the 
sprinklers because these nozzles would also have to spin or they would 
interfere with the sprinkler's drive assembly function. As a result, any 
hose that was attached would just get spun around and snarled up. The 
present invention overcomes this problem and has many unique features as 
discussed hereinabove. 
As to the manner of usage and operation of the present invention, the same 
should be apparent from the above description. Accordingly, no further 
discussion relating to the manner of usage and operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
describcd, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
