Adjustable foot pedal for industrial sewing machines
First Claim
1. The combination of an adjustable foot pedal assembly and an industrial machine which is supported by a stand having legs in contact with a support surface;
- said foot pedal assembly comprisinga treadle plate rockably mounted on said foot pedal assembly beneath and longitudinally in relation to the stand, for operation of the industrial machine supported by the stand;
means for selective transverse adjustment of said foot pedal assembly in relation to a longitudinal axis of the stand, connected to the legs of the stand, spacedly in relation to the support surface, to thereby permit placement of said treadle plate at a position an optimal distance from an operator of said industrial machine;
means for selective vertical adjustment of said foot pedal assembly, in relation to the support surface, connected to the means for selective transverse adjustment, to thereby permit placement of said treadle plate at a position an optimal height from the support surface for the operator of the machine;
means for selective initial angle of tilt adjustment of said treadle plate;
whereby the height, transverse position and initial angle of tilt of said treadle plate can each be adjusted independently of and irregardless of one another.

Abstract
An adjustable foot pedal assembly for control of an industrial machine which is supported by a stand having legs includes a treadle plate rockably mounted on the foot pedal assembly beneath and longitudinal in relation to the stand, for operation of the industrial machine supported by the stand. The foot pedal assembly has a mechanism for selective transverse adjustment of the foot pedal assembly in relation to a longitudinal axis of the stand, connected to the legs of the stand, spacedly in relation to a floor, and a mechanism for selective vertical adjustment of the foot pedal assembly, in relation to the floor, connected to the means for selective transverse adjustment, and a mechanism for selective initial angle of tilt adjustment of the treadle plate.

16. The combination of an adjustable foot pedal assembly and an industrial machine which is supported by a stand having legs in contact with a support surface;
- said foot pedal assembly comprising
a treadle plate rockably mounted on said foot pedal assembly beneath and longitudinally in relation to the stand, for operation of the industrial machine supported by the stand; means for selective transverse adjustment of said foot pedal assembly in relation to a longitudinal axis of the stand, connected to the legs of the stand, spacedly in relation to the support surface; means for selective initial angle of tilt adjustment of said treadle plate; and means for selective vertical adjustment of said foot pedal assembly, in relation to the support surface, connected to the means for selective transverse adjustment, wherein said means for selective vertical adjustment comprises a chain drive mechanism which includes a bar upon which said treadle plate is longitudinally and pivotally mounted beneath the stand, a rigid, rectangular frame connected to the bar upon which said treadle plate is mounted, vertical slides which are spaced apart and parallel in relation to each other, and fixed within said rigid, rectangular frame, a threaded shaft having first and second ends and extending therebetween, vertically, rotatably mounted within said rigid rectangular frame, the first end of said threaded shaft being connected to said rigid rectangular frame, and the second end of said threaded shaft having a toothed gear mounted thereon, a rectangular carriage plate vertically movably attached to said vertical slides and to said threaded shaft within said vertical frame, and rigidly fixed perpendicularly to said bar upon which said treadle plate is longitudinally and pivotally mounted, an elongated housing connected longitudinally to said foot pedal assembly between said foot treadle and said rigid, rectangular frame and having first and second opposed ends, the first end extending into said rigid, rectangular frame at a base thereof and being penetrated by said threaded shaft, the toothed gear mounted on said threaded shaft being completely enclosed within said housing, a continuous chain enclosed entirely within said housing and mounted on the toothed gear of the threaded shaft, a motor positioned at the second end of said elongated housing, said motor having a rotatable motor shaft which penetrates said housing and is attached to said continuous chain, whereby operation of said motor causes rotation of said threaded shaft, resulting in vertical movement of said carriage plate and said bar rigidly fixed thereto.

17. The combination of an adjustable foot pedal assembly and an industrial machine which is supported by a stand having legs in contact with a support surface;
- said foot pedal assembly comprising
a treadle plate rockably mounted on said foot pedal assembly beneath and longitudinally in relation to the stand, for operation of the industrial machine supported by the stand; means for selective transverse adjustment of said foot pedal assembly in relation to a longitudinal axis of the stand, connected to the legs of the stand, spacedly in relation to the support surface; means for selective vertical adjustment of said foot pedal assembly, in relation to the support surface, connected to the means for selective transverse adjustment; and means for selective initial angle of tilt adjustment of said treadle plate;
wherein said means for selective transverse adjustment of said foot pedal assembly comprises a slide mechanism which comprisesa rigid horizontal frame beneath the stand, a slide rod secured within the horizontal frame, spacedly and parallel in relation to the floor, and transversely in relation to the longitudinal axis of the stand, a rigid, flat plate positioned horizontally within the rigid horizontal frame and having a rigid tube fixed to an undersurface thereof, the rigid tube having a bore sized for slidable receipt therein of said slide rod, said rigid, flat plate being connected to said treadle plate for simultaneous movement of said treadle plate as said rigid, flat plate moves transversely in relation to the longitudinal axis of the stand on said slide rod, and means for effecting transverse movement of said rigid, flat plate operatively connected thereto. - View Dependent Claims (18, 19, 20, 21)

22. The combination of an adjustable foot pedal assembly and an industrial machine which is supported by a stand having legs in contact with a support surface;
- said foot pedal assembly comprising
a treadle plate rockably mounted on said foot pedal assembly beneath and longitudinally in relation to the stand, for operation of the industrial machine supported by the stand; means for selective transverse adjustment of said foot pedal assembly in relation to a longitudinal axis of the stand, connected to the legs of the stand, spacedly in relation to the support surface; means for selective vertical adjustment of said foot pedal assembly, in relation to the support surface, connected to the means for selective transverse adjustment; and means for selective initial angle of tilt adjustment of said treadle plate, wherein said means for selective initial angle of tilt adjustment of said treadle plate rockably mounted on said foot pedal assembly comprises a flange fixed transversely and perpendicularly to a bottom surface of a said treadle plate and having an arced series of spaced apart apertures formed therein, a fluid cylinder fixed longitudinally to the underside of said treadle plate perpendicularly in relation to said flange, and spacedly from and directed toward said arced series of spaced apart apertures, and means for selectively activating said fluid cylinder when said treadle plate has been adjusted by pressure from a foot to a preselected initial angle of tilt position, to thereby cause said fluid cylinder to engage a coaligned one of said spaced apart apertures, locking said foot treadle in the preselected position.
