Claims priority, application Great Britain September 24, 1954 4 Claims. (Cl. 29-78) This invention relates to an abrading tool and has for its object to provide such a tool in a convenient and effective form.
According to the invention an abrading tool comprises a handle having a flat face across which extends a longitudinally bowed abrasive strip consisting of a plurality of peripherally toothed substantially parallel resilient wires transversely bent to sinuous form.
in the accompanying drawings:
Figures 1 and 2 respectively are a sectional side view, and a plan from below of one example of the invention.
Figures 3 and 4 are similar views to Figures 1 and 2 respectively showing a modification, and Figures 5 and 6 are similar views to Figures 1 and 2 respectively showing a further modification.
Referring to the first example shown in Figures 1 and 2 the handle 7 is in the form of a block of wood adapted to be grasped in the palm of the hand. The underface 7a of this handle is flat and the end faces 7b curve or incline upwardly towards one another.
Across the fiat underface of the handle 7, extends a detachable abrasive strip 8 which is longitudinally and downwardly bowed and has formed at its ends upturned portions 80 which are adapted to be sprung over the ends of the handle to retain the strip in position. The strip 8 is formed from a. plurality of longitudinally extending resilient wires 8b, each having formed on its periphery in a known manner, a plurality of small abrasive teeth. The wires are united at their ends by being soldered, welded or otherwise secured to transversely extending rods 80 which form parts of the upturned end portions 8a. Viewed in plan from below the wires 8b are each transversely bent to sinusoidal form and are subsequently parallel and contiguous.
In Figures 3 and 4 is shown a modification in which the strip 3 is held positively in a bowed state by means of a wire or strip 9 having hook-shaped ends 9a. This wire or strip 9 is located in a slot 70 formed in the underface of the handle. be initially flat and may be sprung into position between the hook-shaped ends of the wire or strip so as to be held in a bowed form. The strip is subsequently engaged with the handle, as in the first example, by springing the ends 8;; over the end faces 7b of the handle.
In this construction the strip 8 may in Figures 5 and 6 is shown a modification in which the degree of bowing imparted to the strip can be varied, thereby permitting adjustment of the resilience of the strip in use. In this example a wire 10 have a hookshaped end and a screw-threaded end 10b is located in the slot 7c. On the end 10b is a nut 11 and between this nut and the handle 7 is a clamping piece 12 adapted to engage the adjacent end portion in of the strip. It will be appreciated that when the end 10a and the piece 12 are engaged. with opposite ends of the strip tightening of the nut 11 will increase the degree of bowing of the strip and thereby decrease the resilience of the strip in use.
By the present invention dust passing between the wires during abrasion can readily escape from between the strip and handle due to the bowed form of the strip. Further, due to the bowed form of the strip and the resilience of the wires, pressure upon the handle will cause the strip to accommodate itself to irregularities in the surface being abraded. Also a tool is provided which can be used for smoothing any surface and which is more durable than emery cloth, sand paper or abrasive blocks and is more convenient to use than a file, rasp or similar tool.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. An abrading tool comprising a handle having a flat face across which extends a longitudinally bowed abrasive strip consisting of a plurality of peripherally toothed substantially parallel resilient wires transversely bent to sinuous form.
2. An abrading tool as claimed in claim 1 in which the strip has upturned end portions adapted to engage the end faces of the handle.
3. An abrading tool as claimed in claim 2 in which the strip is held in a bowed state by a longitudinally extending member located in a slot in the handle and having parts engaging the end portions of the strip.
4. An abrading tool as claimed in claim 3 in which means is provided for adjusting said parts on the member relative to one another to vary the degree of bowing imparted to the strip.
