Abstract
Abstract A cabinet and work table for a sewing machine having a convertible work supporting bed capable of conversion from a flat work supporting bed to a free-arm bed. The cabinet work supporting surface is divided into two parts, a fixed rear work supporting surface and a laterally/vertically shiftable front work supporting surface. The sewing machine is supported in the cabinet with the work supporting bed forwardly of, contiguous with and spaced above the rear work supporting surface. The shiftable front work supporting surface may be shifted from a first position co-planar with the rear work supporting surface, wherein the sewing machine may be used in a free-arm mode, to a second position co-planar and contiguous to the work supporting bed of the sewing machine for the flat bed sewing mode, wherein the front work supporting surface augments the flat work supporting bed of the sewing machine.

Claim 1
Independent Claim
217 words
A cabinet for a sewing machine having a work supporting bed formed with a rear laterally disposed edge, a front laterally disposed edge, and first and second longitudinal edges joining said laterally disposed edges, said work supporting bed being convertible from a flat bed configuration to a cylinder bed configuration, said cabinet comprising: a rear, laterally elongate, cabinet portion having a rear supporting surface; means for pivotally supporting said sewing machine in a first position with said sewing machine retracted from view and in a second position with said rear laterally disposed edge of said work supporting bed adjacent to and forwardly of said rear cabinet portion, with said first longitudinal edge forwardly of said rear cabinet portion, and with said work supporting bed spaced above said rear work supporting surface; and a vertically shiftable front, laterally elongate, cabinet portion having a front work supporting surface, said shiftable front cabinet portion, when in a lowered position, being located forwardly of and contiguous to said rear cabinet portion laterally beyond said sewing machine first longitudinal edge to the lateral end of said rear cabinet portion, said front work supporting surface being coplanar with said rear work supporting surface whereby said work supporting bed is spaced above said work supporting surfaces of both said rear and front cabinet portions.
Claim 2
Dependent Claim
217 words
A cabinet for a sewing machine having a work supporting bed formed with a rear laterally disposed edge, a front laterally disposed edge, and first and second longitudinal edges joining said laterally disposed edges, said work supporting bed being convertible from a flat bed configuration to a cylinder bed configuration, said cabinet comprising: a rear, laterally elongate, cabinet portion having a rear supporting surface; means for pivotally supporting said sewing machine in a first position with said sewing machine retracted from view and in a second position with said rear laterally disposed edge of said work supporting bed adjacent to and forwardly of said rear cabinet portion, with said first longitudinal edge forwardly of said rear cabinet portion, and with said work supporting bed spaced above said rear work supporting surface; and a vertically shiftable front, laterally elongate, cabinet portion having a front work supporting surface, said shiftable front cabinet portion, when in a lowered position, being located forwardly of and contiguous to said rear cabinet portion laterally beyond said sewing machine first longitudinal edge to the lateral end of said rear cabinet portion, said front work supporting surface being coplanar with said rear work supporting surface whereby said work supporting bed is spaced above said work supporting surfaces of both said rear and front cabinet portions.
Claim 3
Dependent Claim
79 words
A cabinet as set forth in claim 1, wherein said front cabinet portion is supported selectively in a first position with said front work supporting surface co-planar with said rear work supporting surface, both of said front and rear work supporting surfaces being spaced below said work supporting bed, and in a second position with said front work supporting surface co-planar with said work supporting bed and contiguous said first longitudinal edge of said sewing machine work supporting bed.
Claim 4
Dependent Claim
63 words
A cabinet as set forth in claim 1, which further comprises a front rail, said front rail having a fixed upper portion and a lower portion pivotally mounted below said front rail upper portion, whereby, when said supporting means is in said second position, said lower portion may be pivoted to a retracted position allowing greater clearance under said cabinet for an operator.
