Abstract

In a method and apparatus for measuring the flexibility of woven wire-cloth, a sheet (18) to be tested (of known warp/weft count and wire diameter) is clamped to the surface of a board (12) by a flat plate or bar (20) by screwing down wing nuts (22, 24). A second flat bar (26) is similarly mounted by two studs on which wing nuts (28, 30) are screwed Springs are fitted on the studs to hold the bar off the board by a gap arranged to be just greater than the wire cloth thickness so that the latter extends below bar (26) with clearance. A graduated scale (32) is carried by the external face of bar (26) and a clamp (34) is secured to the upper left hand corner of the sheet from which a wire (36) extends downwardly over a pulley (38) to a weight carrier (40) with weight (42). The distance moved by the upper corner under the force of the weight, as measured against the scale, yields a value for the flexibility.

Description

Title: Method and apparatus for testing flexibility of woven wire-cloth
Field of Invention
This invention concerns methods and apparatus for measuring the flexibility of woven wire-cloth.
Background to the invention
For some applications it is important to be able to indicate the ease or otherwise with which a woven wire-cloth can be distorted out of square when subjected to a non- symmetrical drag force.
It is an object of the present invention to provide a method and apparatus by which different similarly sized rectilinear samples of woven wire-cloth can be subjected to such a force and a measurement made of the distortion which results.
Summary of the invention
According to the invention there is provided a method of measuring the flexibility of a rectilinear sample of woven wire-cloth in which the sample is supported against an inclined flat surface having at least two adjoining orthogonal edges, one of which is horizontal and uppermost, and wherein one edge of the sample is aligned with the said uppermost horizontal edge whereby an adjoining perpendicular edge of the sample is generally parallel to the other orthogonal edge of the support surface, the sample is clamped to the supporting surface along or near its opposite edge parallel to the said adjoining edge, a cord or wire is attached to the upper corner of the undamped edge which is of sufficient length as to hang down below the lower edge of the support surface, and a weight is attached to the lower end of the cord or wire, and the distance, if any, through which the upper corner moves in a generally downward sense parallel to the support surface, under the force exerted by gravity on the weight when attached to the wire or cord, is noted and logged for the sample.
Typically the inclination of the support surface is in the range 10° to 30° to the vertical.
Conveniently the method further comprises the step of providing a graduated scale adjacent the said undamped edge of the sample, noting the position of the upper corner relative to the graduated scale prior to loading the sample with the weight, and noting the new position of the upper corner of the sample relative to the scale, after the sample has been put under load.
The invention also lies in apparatus for performing the method comprising a frame carrying a board having a flat support surface which is arranged at a fixed angle to the vertical, a bar movable towards and away from the surface of the board to allow the edge of a sheet of wire cloth to be located therebetween, means for clamping the bar in place by tightly securing the bar to the board or the frame, thereby to clamp one edge of the wire- cloth between the bar and the support surface, an upper region or edge of the frame or board being marked with a line or provided with an edge defining member which in use extends generally horizontally, perpendicular to the clamping bar, the line or edge defining a reference line with which in use the upper horizontal edge of a rectilinear sample sheet of wire cloth is aligned before being clamped, a second bar parallel to the first bar and laterally spaced therefrom by a distance such that in use the parallel undamped edge of the sheet will protrude beyond the second bar, spacing means serving to space the second bar away from the support surface so that while the wire-cloth is free to slide therebetween it is constrained to lie flat on the said surface, an attachment means which is securable to the upper corner of the undamped edge of the sheet adjacent the second bar, a wire or cord secured at one end to the attachment means and having weight carrying means secured to its other end, the wire or cord being long enough to extend in use below the lower edge of the board and to hang freely in a vertical sense therebelow, a weight detachably securable to the carrying means thereby to drag the undamped edge region of the wire-cloth in a generally downward sense, and a graduated scale located relative to the surface so as in use to be adjacent the undamped wire-cloth edge protruding beyond the said second bar to enable any movement of the upper corner thereof due to the addition of the weight, relative to the surface, to be measured, by reading off the position of the said upper corner from the scale before and after the weight has been secured to the carrying means.
Preferably the surface of the board is smooth so as to reduce friction between it and the underside of the sheet of wire cloth.
Preferably the graduated scale is mounted on, carried by, printed, engraved or otherwise formed on the frame or the support surface or on the face of the said second bar.
Conveniently the said second bar is attached to the board (or frame) by screw threaded studs which extend through two holes in the bar, and is held in place by wing nuts, and compression springs are located and held captive between the bar and the board, to space the underside of the bar from the board by a distance, deteπnined by the compressed length of the springs, which is thereby adjustable to be just greater than the thickness of the wire cloth, so that the latter can slide freely between the second bar and the support surface.
Likewise the clamping bar may also be mounted to the frame or board by screw threaded studs which protrude through two holes in the bar and whereby in use the bar is clamped to the board with wire-cloth therebetween by screwing down wingnuts onto the protruding studs.
To assist in achieving a clamping force, compression springs may be fitted between the wing nuts and the bar, which springs are compressed as the wing nuts are tightened, and the spring force acts through the bar to clamp the wire-cloth. In apparatus as aforesaid the fixed angle is preferably in the range 10° to 30° of vertical.
In a preferred embodiment of the invention the frame is adapted to sit on a table or desk close to an edge thereof, and a lower region of the board and/or frame is cut-away to provide a recess, a pulley is mounted in the recess for rotation about a horizontal axis, the position of the recess being selected so that the pulley is in line with the path of the wire or cord, when attached to the top corner of the wire-cloth, whereby in use the cord or wire runs over the pulley and thereby changes direction from its run parallel to the support surface to the vertical run to the weight carrying means.
In the methods and apparatus as aforesaid the wire-cloth sample is typically in the range 300-400mm square.
Likewise in the methods and apparatus as aforesaid the weight is of the order of 1kg.
The invention will now be described with reference to the accompanying drawing in which he single Figure is a perspective view of apparatus for performing the invention.
In the drawing a frame 10 provides a support for a flat board 12. The base 14 of the frame is shown resting on a tabletop 16 close to an edge thereof, so that the front edge of the base 14 just overhangs the tabletop edge.
A sheet 18 of wire cloth to be tested (of known warp and weft count and wire diameter) is clamped to the surface of the board 12 by a flat plate or bar 20 which can be released or clamped as required by unscrewing or screwing down wing nuts 22, 24.
A second similar flat bar 26 is similarly mounted to the board/frame moulding by two studs (not shown) on which wing nuts 28, 30 are screwed. Springs (not shown) are fitted on the studs between the bar 26 and the board 12, to hold the bar off the board by a distance determined by how tightly the wing nuts are screwed down. The gap is arranged to be just greater than the wire cloth thickness so that the latter extends below bar 26 with clearance.
A graduated scale 32 is carried by the external face of bar 26 and a clamp 34 is secured to the upper left hand corner of the wire cloth sheet from which a wire 36 extends downwardly over a pulley 38 to a weight carrier 40 on which a weight 42 can be removably fitted.
Typically the board 12 is formed from FORMICA so that the front face is smooth and does not resist sliding movement of the wire cloth thereover.
