Abstract
Abstract A combination grain mill and dough mixer arranged so as to be operated by a common power source, that power source preferably being an electric motor having an armature shaft that turns simultaneously both the grain mill and a kneader or agitator portion of the mixer. A preferred form of the grain mill being one utilizing a fixed grinding stone and a stone grinding wheel with flat surfaces of each arranged proximate to one another and the stone wheel adapted to be turned by the shaft of the electric motor, with grain deposited between the stones through an appropriate feed opening formed through the fixed grinding stone. Grinding of the grain into flour or meal is accomplished by the action of the face of the stone grinding wheel turned closely proximate to the face of the fixed stone, the ground grain falling as flour or meal from between the stones into a drawer within the housing. The flour or meal is then poured, along with other dough ingredients, into a bowl portion of the mixer wherein the kneader or agitator is turned through a bevel gear arrangement connected by a belt to a pulley that is secured to the shaft of the electric motor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
245 words
A combination grain mill and dough mixer comprising a housing having side walls, a front wall, a rear wall, a top wall and a bottom wall; a power source arranged in said housing producing a rotary output from a shaft thereof; a grinding wheel attached to said shaft so as to turn therewith; a fixed grinding member, secured within said housing so as to be proximate to said grinding wheel, with grinding faces of each extending parallel to and mutually opposite to one another; means disposed below said stone grinding wheel and and fixed grinding stone, for receiving meal falling from between said stone grinding wheel and fixed grinding stone; means for feeding grain between said stone grinding wheel and fixed grinding stone; means connected to said shaft for transferring power therefrom to a dough mixer; mixer mounting means extending from a side wall of said housing on which said dough mixer is mounted said mixer mounting means comprising a mixer mounting plate extending as a shelf outwardly from said side wall and at a spaced distance above the bottom wall of said housing; an agitator blade rotated by said power transfer means, and clamping means carried by the mixer mounting means; and container means having a periphery arranged to be releasibly attached beneath and to be immovably clamped said mixer mounting plate by said clamping means, with the agitator blade therein, whereby the blade can be rotated and dough mixed in the container means.
Claim 2
Dependent Claim
245 words
A combination grain mill and dough mixer comprising a housing having side walls, a front wall, a rear wall, a top wall and a bottom wall; a power source arranged in said housing producing a rotary output from a shaft thereof; a grinding wheel attached to said shaft so as to turn therewith; a fixed grinding member, secured within said housing so as to be proximate to said grinding wheel, with grinding faces of each extending parallel to and mutually opposite to one another; means disposed below said stone grinding wheel and and fixed grinding stone, for receiving meal falling from between said stone grinding wheel and fixed grinding stone; means for feeding grain between said stone grinding wheel and fixed grinding stone; means connected to said shaft for transferring power therefrom to a dough mixer; mixer mounting means extending from a side wall of said housing on which said dough mixer is mounted said mixer mounting means comprising a mixer mounting plate extending as a shelf outwardly from said side wall and at a spaced distance above the bottom wall of said housing; an agitator blade rotated by said power transfer means, and clamping means carried by the mixer mounting means; and container means having a periphery arranged to be releasibly attached beneath and to be immovably clamped said mixer mounting plate by said clamping means, with the agitator blade therein, whereby the blade can be rotated and dough mixed in the container means.
Claim 3
Dependent Claim
52 words
A combination grain mill and dough mixer as recited in claim 1, wherein the power source consists of an electric motor, and said shaft portion of said power source is the armature of said electric motor that is arranged such that the ends thereof extend from opposite ends of said electric motor.
Claim 4
Dependent Claim
78 words
A combination grain mill and dough mixer as recited in claim 1, wherein the means for transferring power for the electric motor to the dough mixer consists of a pulley connected to the end of said shaft opposite to said grinding wheel; a gearing arrangement carried by said mixer mounting plate; a shaft extended from said gearing arrangement; a pulley secured to said shaft opposite to said gearing arrangement; and drive belt means arranged between said respective pulleys.
Claim 5
Dependent Claim
59 words
A combination grain mill and dough mixer as recited in claim 3, wherein said gear arrangement consists of a bevel pinion gear meshing, at a ninety degree angle with a second bevel gear effecting thereby a ninety degree transmission of rotary motion between said shaft and said agitator blade that extends from and is turned by said bevel gear.
Claim 6
Dependent Claim
52 words
A combination grain mill and dough mixer as recited in claim 1, wherein the power source consists of an electric motor, and said shaft portion of said power source is the armature of said electric motor that is arranged such that the ends thereof extend from opposite ends of said electric motor.
Claim 7
Dependent Claim
43 words
A combination grain mill and dough mixer as recited in claim 5, wherein the means connected to said shaft for transferring power therefrom to a dough mixer includes drive means within the cover means extending outwardly from the rear wall of the housing.
Claim 8
Dependent Claim
248 words
A combination grain mill and dough mixer comprising a housing having side walls, a front wall, a rear wall, a top wall and a bottom wall; a power source arranged in said housing producing a rotary output from a shaft thereof; a grinding wheel attached to said shaft so as to turn therewith; a fixed grinding member, secured within said housing so as to be proximate to said grinding wheel, with grinding faces of each extending parallel to and mutually opposite to one another; means disposed below said stone grinding wheel and fixed grinding stone, for receiving meal falling from between said stone grinding wheel and fixed grinding stone; means for feeding grain between said stone grinding wheel and fixed grinding stone; means connected to said shaft for transferring power therefrom to a dough mixer; mixer mounting means at least partially extending from a side wall of said housing on which said dough mixer is mounted, said mixer mounting means including a mixer mounting member extending outwardly from said side wall at a spaced distance above the bottom wall of said housing; an agitator blade rotated by said power transfer means; clamping means adapted to be attached to the mixer mounting means; and container means having a periphery arranged to be releasably attached to and to be immovably clamped to said mixer mounting member so as to be positioned therebelow with the agitator blade therein, whereby the blade can be rotated and dough mixed in said container means.
