Abstract
Abstract Apparatus for testing fabrics and the like for wearability and generally comprises a generally horizontally extending base member including a broad upper surface, an anvil member having a longitudinally extending lofty upper-side, clamp means at the two anvil ends for removably attaching the test fabric in stretched condition above the anvil upper-side, a shoe member overlying the anvil and adapted to firmly downwardly abut the test fabric, powering means ultimately attached to the shoe member for causing repeated longitudinally reciprocatable movement thereof over a lengthy time period while abutting the test fabric, and other desirable features for implementing the apparatus purposes. For preferred apparatus embodiments, a pair of transversely separated anvil members are employed whereby the same kind of woven fabric can be tested simultaneously for wearability both in the warp and weft directions of the test fabrics.

Claim 1
Independent Claim
232 words
Apparatus for testing the expected wearability of fabrics and other sheet materials, said apparatus comprising: A. A generally horizontally extending base member including a broad upper surface therefor; B. An anvil member attached to the base member and including a generally horizontal longitudinally extending broad upper-side located loftily above the base member upper surface, said anvil member upper-side extending lengthily longitudinally between two transversely extending anvil edges including a front-edge and a rear-edge; C. A pair of clamps including a front-clamp and a rear-clamp located terminally of and separated by said anvil, said clamps being adapted to removably attach a longitudinally extending sheet material test strip in stretched condition in overlying relationship with a working-surface anvil portion near the upper-side thereof; D. Clamp-tensioning means tending to maximize the longitudinal distance between the front-clamp and the rear-clamp, said clamp-tensioning means being longitudinally resiliently yieldable for temporarily reducing the distance between said clamps; E. A generally horizontal longitudinally extending track means attached to the base member and located above the base member upper surface; F. A shoe member of vertically adjustable elevation and overlying the anvil upper-side, said shoe member being longitudinally reciprocatably associated along said track means; G. Shoe-tensioning means tending to press the shoe member downwardly toward the anvil and the test sheet stretched therealong; and H. Powering means attached to the shoe member for causing longitudinally reciprocations of the shoe member.
Claim 2
Dependent Claim
232 words
Apparatus for testing the expected wearability of fabrics and other sheet materials, said apparatus comprising: A. A generally horizontally extending base member including a broad upper surface therefor; B. An anvil member attached to the base member and including a generally horizontal longitudinally extending broad upper-side located loftily above the base member upper surface, said anvil member upper-side extending lengthily longitudinally between two transversely extending anvil edges including a front-edge and a rear-edge; C. A pair of clamps including a front-clamp and a rear-clamp located terminally of and separated by said anvil, said clamps being adapted to removably attach a longitudinally extending sheet material test strip in stretched condition in overlying relationship with a working-surface anvil portion near the upper-side thereof; D. Clamp-tensioning means tending to maximize the longitudinal distance between the front-clamp and the rear-clamp, said clamp-tensioning means being longitudinally resiliently yieldable for temporarily reducing the distance between said clamps; E. A generally horizontal longitudinally extending track means attached to the base member and located above the base member upper surface; F. A shoe member of vertically adjustable elevation and overlying the anvil upper-side, said shoe member being longitudinally reciprocatably associated along said track means; G. Shoe-tensioning means tending to press the shoe member downwardly toward the anvil and the test sheet stretched therealong; and H. Powering means attached to the shoe member for causing longitudinally reciprocations of the shoe member.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1 wherein the anvil upper-side has a resiliently compressible pad superimposed upon and attached to said anvil upper-side whereby the longitudinally stretched and removably clamped test sheet material is in firm abutment downwardly against said pad as an anvil supported working-surface.
Claim 4
Dependent Claim
59 words
The apparatus of claim 1 wherein the track means comprises at least one substantially horizontal longitudinally extending rail maintained at substantially constant elevation loftily above the base member upper surface, there being a slider member slidably surrounding and longitudinally reciprocatably movable along said track rail, and the shoe member being ultimately connected to the slider member and co-reciprocatable therewith.
Claim 5
Dependent Claim
38 words
The apparatus of claim 3 wherein the powering meAns comprises an electric motor including a revolvable eccentric-means thereon, and an elongate crank arm pivotably connected to said revolvable eccentric-means and also to said longitudinally reciprocatably movable slider member.
Claim 6
Dependent Claim
47 words
The apparatus of claim 1 wherein the clamp-tensioning means comprises a substantially horizontal longitudinally extending elongate helical spring bearing against a clamp member and removably attached to the apparatus whereby the sheet material stretching tension is selectable depending upon the tension characteristics of the chosen helical spring.
Claim 7
Dependent Claim
41 words
The apparatus of claim 5 wherein said elongate helical spring surrounds a substantially horizontal longitudinally extending spacer-rod having at least one terminus thereof removably attached to a clamp member to facilitate helical spring substitution for selectable tension upon the sheet material.
Claim 8
Dependent Claim
118 words
The apparatus of claim 1 wherein the shoe member is attached to the lower portion of an upright support-bar, the support-bar upper portion being slidably surrounded by a tubular collar maintained at constant elevation above the base member upper surface, a set-screw passing through the tubular collar to vertically adjust the shoe member elevation whenever the apparatus operator is clamping andeclamping the tested sheet material, the shoe-tensioning means comprising a coil spring surrounding the support-bar between the shoe member and the upright tubular collar, said coil spring being removable from surrounding relationship with the support-bar whereby the shoe member downward force against the tested fabric is selectable depending upon the tension resiliency characteristics of the chosen coil spring.
Claim 9
Dependent Claim
30 words
The apparatus of claim 7 wherein the shoe member comprises a removably connected bottom-panel portion of selectable texture and for making firm though reciprocatable contact with the tested sheet material.
Claim 10
Dependent Claim
216 words
The apparatus of claim 1 adapted for simultaneously testing the same kind of textile fabric sheet material in the warp and weft directions thereof, there being a pair of anvil members in substantial parallelism and spaced on opposite sides of an imaginary longitudinally extending vertical-plane; wherein each of said anvil members is provided with a pair of terminal clamps and further comprises independent clamp-tensioning means for each pair; wherein the track means comprises a pair of substantially horizontal longitudinally extending elongate parallel rails located between the anvils and maintained at substantial co-elevation above the base member upper surface, each of said track rails being provided with a slider member slidably surrounding and longitudinally reciprocatably movable therealong, said slider members being attached together in co-reciprocatable relationship with a transversely extending web; wherein there is a pair of shoe members overlying the respective anvil members, each of said shoe members being ultimately connected to a sturdy columnar member extending rigidly uprightly from said transversely extending web; and wherein the powering means comprises an electric motor connected to the base member and including revolving eccentric means, and an elongate crank-arm lying along said imaginary upright-plane and being pivotably connected both to the motor shaft through the eccentric means carried thereby and also to the slider members connecting transverse web.
