DESCRIPTION OF THE INVENTION 
Referring to the drawings in detail and, in particular to FIG. 1, a cooker 
- mixer apparatus of this invention, indicated generally at 12, is shown 
as mounted on a cooking stove assembly 14 and operably connected to a 
power supply outlet 16. The cooking stove assembly 14 includes a plurality 
of gas burners 18, each associated and controlled by a control knob member 
20. Although a cooking stove assembly 14 with gas burners 18 is 
illustrated, it is obvious that any type of heating structure (electric, 
propane, open fire, etc.) could be used to heat the cooker - mixer 
apparatus 12 and any food products contained therein. 
The power supply outlet 16 is of a conventional nature supplied with 110 
volt AC current to an outlet receptacle 22 as is well known. 
The cooker - mixer apparatus 12 includes a cooker means 22 having a mixer 
means 24 mounted thereon. The cooker means 22 resembles a conventional 
pressure cooker type structure and includes a container assembly 26 having 
a cover lid assembly 28 mounted thereon. 
As seen in FIG. 3, the container assembly 26 includes a main container 
member 30 having a handle member 32 connected thereto. The container 
member 30 resembles a standard cooking pot having a bottom wall 34 
integral with a vertical sidewall 36. A top surface 38 of the sidewall 36 
is formed with a plurality of spaced notches 40 for reasons to be 
explained. The container member 30 has a large entrance opening 42 to be 
selectively closed by the cover lid assembly 28. 
The handle member 32 includes a U-shaped main body 44 integral with 
connector legs 46 which are secured by rivets 48 to the sidewall 36 of the 
container member 30 (FIG. 1). 
The cover lid assembly 28 includes a lid member 50 having a latch assembly 
52 connected thereto. The lid member 50 includes a top main lid body 54 
having a downwardly depending connector rim 56 about its periphery. The 
main lid body 54 has a central flat section 58 with a central hole 60 
therein to receive a portion of the mixer means 24 as will be explained. 
Also, a top surface 62 of the lid body 54 is provided with a curved 
observation window 64 to allow visual surveillance over any food product 
within the main container member 30. 
The connector rim 56 is provided with inwardly projecting anchor lugs 66, 
each one operably associated with one of the spaced notches 40 on the 
container member 30 in the interconnected condition. This will prevent 
relative rotational movement between the container member 30 and the cover 
lid assembly 28. 
Also, the connector rim 56 is provided with diametrically opposed latch 
projections 68 for connection to the latch assembly 52. 
As shown in FIGS. 1 and 3, the latch assembly 52 includes a pair of opposed 
connector latch assemblies 70 secured to upper outer areas 71 of the main 
container member 30. Each connector latch member 70 includes a cam 
actuator 72 connected to an anchor ring 73 which is releasably connectable 
to respective ones of the latch projections 68. The latch assemblies 52 
are of a conventional type and further discussion thereof is not deemed 
necessary. 
The mixer means 24 includes a power assembly 74 connected to a mixer 
assembly 76 by a connector shaft assembly 78. The power assembly 74 
includes a drive motor member 80, a power cord member 82 to connect the 
drive motor member 80 to the output receptacle 22, and a control assembly 
84 mounted on the drive motor member 80. 
The drive motor member 80 includes a variable speed motor member 86 
operable to drive an output shaft 88 and mounted securely against the flat 
section 58 of the main lid body 54. A drive hub 90 fits in the central 
hold 60 of the main lid body 54 (FIG. 3). 
The power cord member 82 has an electrical cord 92 with an outer end 
connected to a plug member 94. As seen in FIG. 1, the plug member 94 is 
placed in the electrical receptacle 22 to provide electrical current to 
the motor member 80. 
The control assembly 84 includes a control knob 96 operably connected to 
the variable speed motor member 86 and associated with speed indicia 98 on 
a top surface portion 101 of the motor member 80. The speed indicia 98 
indicates speed from "OFF - LOW - MEDIUM - HIGH" which can be selected by 
the operator as desired. 
As shown in FIG. 3, the connector shaft assembly 78 includes a connector 
coupling 103 having an upper end section 105 secured to the output shaft 
88 and a lower end section 107 secured to a drive shaft 108. The connector 
coupling 103 has a hole therethrough and connection to the subject shafts 
are by set screw members 109. 
A lower end of the drive shaft 108 is formed with a threaded section 110 to 
hold a pair of spaced wing nuts 112 therein to clamp the mixer assembly 76 
therebetween (FIG. 3). 
The mixer assembly 76 includes a main hub member 114 with a plurality of 
equally spaced, namely four, paddle assemblies 116 integral therewith. The 
main hub member 114 includes a central body 118 with a hole 120 to receive 
the drive shaft 108 therethrough and a circular indentation 122 in a 
bottom surface 124. The circular indentation 122 receives a lower one of 
the wing nuts 112 therein to prevent contact thereof with the bottom wall 
34 of the container member 30. 
Each paddle assembly 116 includes a spoke member 124 with an inner end 
portion 126 integral with the main hub member 114 and an outer end portion 
128 integral with a wiper end member 130. The spoke member 124 is formed 
with an arcuate central body 132 having a plurality of spaced material 
flow channels or openings 134 therein. The central body 132 is curved 
rearwardly of the direction of rotation for easy wiping action. Also, the 
central body 132 has a lower surface 136 adjacent the bottom wall 34 of 
the container member 30 and extended upwardly therefrom for a combination 
mixing and wiping action. 
Each wiper end member 130 is formed with a connector section 138 integral 
with a pointed end section 140. The narrowing of the end section 140 in 
combination with the wiper end member 130 being constructed of resilient 
material, such as rubber, achieves a flexible wiping of the sidewalls 36 
of the container member 30 during operation of the cooker - mixer 
apparatus 12 of this invention. 
USE AND OPERATION 
In the use and operation of the cooker - mixer apparatus 12 of this 
invention, the same is shown in FIG. 1 as mounted on a gas burner 18 of 
the cooking stove assembly 14. The power cord member 82 is shown with the 
plug member 94 mounted in the outlet receptacle 22 to provide power to the 
control assembly 84 of the power assembly 74 of the mixer means 24. 
A food product to be cooked and mixed is placed within the container 
assembly 26 with the lid assembly 28 secured thereto as shown in FIG. 1. 
The control knob 96 can be selectively rotated from "OFF" to "LOW" - 
"MEDIUM" or "HIGH" to energize the variable speed motor member 86 and 
drive the mixer assembly 76. Rotation is achieved in the direction shown 
by an arrow 142 in FIG. 2. 
The paddle assemblies 116 operate to thoroughly mix the food product while 
wiping the bottom wall 34 and sidewall 36 of the container member 30 and 
prevent over heating and subsequent burning of the food product. 
After sufficient cooking and mixing, the latch assemblies 52 are releasable 
to remove the lid assembly 28 from the container assembly 26. This permits 
easy removal of the food product in the main container member 30. 
It is noted that cooperation of the anchor lugs 66 with the latch notches 
40 provides a locking feature to prevent movement between the container 
assembly 26 and the lid assembly 28. This is especially important as the 
motor member 80 would create a torque during operation tending to rotate 
the interconnected lid assembly 28. 
It is obvious that the cooker - mixer apparatus of this invention is sturdy 
in construction, easy to use, and provides a needed combination of cooker 
and mixer. The cooker means of the cooker - mixer apparatus can be 
constructed in a sealed manner to operate similar to a pressure cooker. 
While the invention has been described in conjuntion with preferred 
specific embodiments thereof, it will be understood that this description 
is intended to illustrate and not to limit the scope of the invention, 
which is defined by the following claims.
