In Germany April 30, 1937 4 Claims.
The present invention relates to a hand carding or'teasing appliance or tool, that is provided with a piece of clamped and tensioned card clothing. The invention specially relates to a handle or holder, such as for instance is used for the cleaning of carding liners.
Most of such holders have the disadvantage, that they have a plane working surface, whereas a curved or arcuate working surface is more advantageous in so far as it takes the natural path of the working motion into consideration.
'.In so far as such holders are already known,
they have apart from the disadvantages inherent to such carding holders having a plane working surface, the further disadvantage that their tensioning device is complicated and un-' porting surface is used for tensioning the lining and is therefore made in two parts. The two parts of the supporting surface are displaced relatively to each other, whilst being tensioned, thereby rendering a, part of the teeth ineffective.
These defects are eliminated in the case of the holder, according to the present invention, wherein the holder is provided with a suitably cambered working and supporting surface, so constructed that it is possible to tension the card clothing, without causing a part of the carding or teasing teeth to loose their supporting surface.
The rigid cambered or arcuate supporting surface upon which the card clothing rests, is a onepiece member, and remains unaltered by a tensioning or clamping operation. A resilient tensioning plate, which presents a pronounced camher in the opposite. direction to the supporting surface, serves to tension the card clothing. The latter to be tensioned, is reinforced on both its longitudinal sides in a manner known perse with U shaped clamping rails in which the supporting plate and also the tensioning plate engage at their longitudinal edges. I
By flattening the cambered tensioning plate more or less, thereby causing it to become wider,
the card clothing is tensioned in a perfect and safe manner over the cambered supporting surface, so that all the teeth are fully supported.
The hitherto known tensioning devices for the same purpose have inaddition the disadvantage at least in part, that the uniform gripping and the parallel displacement of the U shaped clamp? ing rails in the case of long appliances is by no means assured. If this however be not the case, 5 then the card clothing is either tensioned unevenly or not at all, which may lead to the card clothing being torn off during working, at a nontensioned or badly tensioned point.
Finally cleaning card clothing appliances are 10' also known, wherein the card clothing is easily crinkled or kinked when ten'sioning it. These defects also have been eliminated in the case of the present invention by the fact, that tensioning is effected by pressing the resilient tensioning plate flat.
In order that the invention may be clearly understood and readily carried into effect ref erence is made to the accompanying. drawings which show diagrammatically and by way of 20 example several constructional forms of hand carding or teasing appliances in accordance with the present invention.
Figure 1 is a side view of a hand carding cleaning or teasing appliance or tool in accordance 25 with the present invention.
Figure 2 partly in section, is a plan of Figure 1.
Figure 3 is an axial section.
Figure 4 is a side elevation of the appliance or' 30 tool, having another kind of handle.
Figure 5 is a cross section of Figure 4.
Figures 6, 9 and '7, 10 and 8, 11 are plan views, side viewsand axial cross sections respectively of two smaller appliances of this type.
The appliance according to the present invention is provided with a piece of card clothing a. This rests on a plate shaped support b which may be cambered, Figures-1 8, or flat as in Figures 9-11. The card clothing a is provided at 40 both opposite longitudinal edges with gripper or clamping rails 0, having a v or U shaped cross section, and is adapted to be loosely pushed over a supporting plate b the gripper or clamping rails clamping them together.
The card clothing a is now tensioned tightly by means of a cambered resilient tensioning plate d on the supporting surface b. This arcuate tensioning plate at lies with its longitudinal edges within the gripper or clamping rails c and 50 stretches the clothing a tight over the support b, when it is flattened by pressure, by reason of its ends sliding outwards on the support b.
The tensioning member d is fixed at its middle to the extremity of a handle ,e and is tensioned I5 by means of a screw bolt with its wing nut g or the like adapted to be screwed thereon. If the nut g is screwed tight, it abuts against the exterior surface of the handle e, through which the bolt ,1 passes, thereby forcing the support b against the handle 6, which is of course equivalent to depressing the tensioning member 01, i. e., to secure and tension the clothing a.
On unscrewing the wing nut g the tensioned members a and d are released, and the arcuate.
tensioning member (1 again assumes its fully arcuate camber by reason of its resiliency. In order to ensure efficient guiding, the support I) is, in the case of long, and/or wide designs necessary for appliances for use in cleaning the scratch ribbons, provided with guide pins h which pass loosely through corresponding holes provided in the tensioning plate (2.
Figures 1-3 and 6-11 show appliances with Wooden handles e, whereas the constructional forms of Figures 4 and 5 are provided with stronger handles. Here the handle e is made of metal that is to say the fixing end 2' which is weakened by the bolt 1 is made of metal which is clamped by means of a round knurled nut g. The free hook-shaped extremity k of the handle e is also of metal in order to protect it against wear. The two handle ends 2' and k are preferably connected together by means of a metal rib l, to which suitable wooden strips are fixed on either side.
Figures 6, '7, 8 on the one hand and Figures 9, 10 and 11 on the other hand illustrate the same appliances, but of a lesser width. These appliances are intended for cleaning files, roughening surfaces and the like.
What I claim is:
1. A hand carding tool comprising a stretchable toothed carding member, a backing providing overall support for the carding teeth, an elastic arcuate tensioning member having opposite edges engaging along opposite edges of said carding member, said elastic tensioning member being bowed between said last-mentioned edges in such a manner as to stretch said carding member relatively to said backing, means said carding member,
for flattening the curvature and elongation of said elastic tensioning members and backing, said curvature flattening means also forming a connection between said holder and other parts of the tool.
2. A hand carding tool comprising a tensionable toothed carding member, a backing providing overall support for the carding teeth, engaging means extending continuously along opposite edges of said carding member, tensioning means having edges co-extensive with said engaging means and exerting uniformly distributed outward thrust along said opposite edges of the carding member substantially tangentially to its contact with the backing, means for varying the thrust of said. tensioning means, and cooperating guide means on the backing and curvature flattening means.
3. A hand carding tool comprising a tensionable toothed carding member, a backing providing overall support for the carding teeth, engaging means extending continuously along opposite edges of said carding member, tensioning means having edges co-extensive with said engaging means and exerting uniformly distributed outward thrust along said opposite edges of the carding member substantially tangentially to its contact with the backing, and means for varying the thrust of said tensioning means, the engaging means on the carding member being in the form of rails of U-section in the grooves of which the edges of the tensioning means engage.
4. A hand carding tool comprising a stretchable toothed carding member, an elastic arcuate tensioning member having opposite edges engaging along opposite edges of said carding member, said elastic tensioning member being bowed between said last-mentioned edges in such a manner as to stretch said carding member,-
