Abstract
Abstract A fabric stretcher device comprising an enlarged, generally rectangular base providing a top planar surface, a first pair of rails fixed relative to two adjoining side edges of said planar surface and a second pair of rails including adjustment means to adjustably position said second pair relative to the respective third and fourth edges of the planar surface. Upwardly struck barbs are provided in a closely spaced relation along the lengths of all four rails to engage through and position the perimeter portion of a piece of fabric to be stretched. The adjustment means are actuated to impart evenly distributed lateral and longitudinal tensioning forces to the fabric.

Claim 1
Independent Claim
263 words
An adjustable stretcher device for stretching a generally rectangular piece of fabric comprising; A. a generally rectangular base member providing, 1. a planar top surface; B. a pair of side rails fixed in an angular relation relative to a first pair of adjoining side edges of said planar top surface and including, 1. at least one row of relatively closely spaced barbs along the lengths of both of said pair to engage through and hold corresponding, adjoining edge portions of the piece of fabric to be stretched; C. a third rail similar to said pair, to similarly engage and hold a third edge portion of the piece of fabric; D. a first adjustment and tensioning means connecting between a third edge of said base member and said third rail to adjust said third rail relative to the first of said pair to conform with a first dimension of the fabric piece and to apply tension forces along the length of said first dimension; E. a fourth rail, similar to said pair and third rail, to similarly engage and hold the fourth edge portion of the piece of fabric; F. a second adjustment and tensioning means connecting between the fourth edge of said base member and said fourth rail to adjust said fourth rail relative to the second of said pair to conform with a second dimension of the fabric piece and to apply tension forces along the length of said second dimension; G. adjustable extension means connecting between said first and second adjustment and tensioning means and the respective third and fourth rails.

An adjustable stretcher device for stretching a generally rectangular piece of fabric comprising; A. a generally rectangular base member providing, 1. a planar top surface; B. a pair of side rails fixed in an angular relation relative to a first pair of adjoining side edges of said planar top surface and including, 1. at least one row of relatively closely spaced barbs along the lengths of both of said pair to engage through and hold corresponding, adjoining edge portions of the piece of fabric to be stretched; C. a third rail similar to said pair, to similarly engage and hold a third edge portion of the piece of fabric; D. a first adjustment and tensioning means connecting between a third edge of said base member and said third rail to adjust said third rail relative to the first of said pair to conform with a first dimension of the fabric piece and to apply tension forces along the length of said first dimension; E. a fourth rail, similar to said pair and third rail, to similarly engage and hold the fourth edge portion of the piece of fabric; F. a second adjustment and tensioning means connecting between the fourth edge of said base member and said fourth rail to adjust said fourth rail relative to the second of said pair to conform with a second dimension of the fabric piece and to apply tension forces along the length of said second dimension; G. adjustable extension means connecting between said first and second adjustment and tensioning means and the respective third and fourth rails.
Claim 3
Dependent Claim
97 words
The adjustable stretcher device as defined in claim 1 wherein said first adjustment and tensioning means comprises two spaced apart, elongated eye-bolts, each having an inner end removably linked to said third rail and a screw threaded outer end extending through a hole in an upwardly extending flange of an angle-iron, fixed relative to said third edge, nut means being carried on said screw threaded outer end to engage against the outer surface of said flange to adjust said third rail inwardly or outwardly, relative to the first of said pair, upon proper manipulation of said nut.
Claim 4
Dependent Claim
20 words
The adjustable stretcher device as defined in claim 2 including elongated handle means fixed to each of said nut means.
Claim 5
Dependent Claim
23 words
The adjustable stretcher device as defined in claim 2 including a plurality of spaced apart holes in said flange along the length thereof.
Claim 6
Dependent Claim
20 words
The adjustable stretcher device as defined in claim 2 including a plurality of spaced apart holes in said angleiron flange.
Claim 7
Dependent Claim
26 words
The adjustable stretcher device as defined in claim 2 including chain means removably and adjustably connecting between each of said linked ends and said third rail.
Claim 8
Dependent Claim
26 words
The adjustable stretcher device as defined in claim 2 including chain means removably and adjustably connecting between each of said linked ends and said fourth rail.
Claim 9
Dependent Claim
30 words
The adjustable stretcher device as defined in claim 1 including adjustable extension means connecting between said first and second adjustment and tensioning means and the respective third and fourth rails.
Claim 10
Dependent Claim
18 words
The adjustable stretcher device as defined in claim 1 wherein said barbs are upwardly struck from said rails.
