HARRY ZIMMERMAN, OF LAKELAND, FLORIDA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE YERGES MANUFACTURING COMPANY, OF FREMONT, OHIO, A CORPORATION OF OHIO BIAS BUFFER Application filed October 19, 1925. Serial No. 63,562.
This invention relates to handling fabric for resistance to abrasion.
This invention has utility when incorporated in buffing wheels, as well as in selvage or binding.
Referring to the drawings:
Fig. 1 is a side elevation, with parts broken away, of an embodiment of the invention in a multi-ply bufling section;
Fig. 2 is a view of a bias edge providing strip as used in multiple for producing transversely a single ply extent in the buffing wheel section of Fig. 1;
' Fig. 3 is a pleated or folded type of strip of fabric as built into transverse series for buffer disks;
Fig. 4 is a view of a folded type of strip.
wherein instead of the folds being reversed as in Fig. 3, they are continuous or wound in the form of a helix with abutting or lapping to the extent desired in the production of two or more thicknesses of material for the strip;
Fig. 5 shows an embodiment or set-up for using the plies in a buffing jack;
Fig. 6 is a side elevation, with parts broken away, of a strip built up radial stitch assembled multi-ply buffing wheel section;
Fig. 7 is a side elevation, with parts broken away, of a. strip built up tangential stitch assembled multi-ply bufiing wheel section;
Fig. 8 is a side elevation, with parts broken away,"0f a strip built up spiral stitch assembled multi-ply bufling wheel section;
Fig. 9 is a side elevation, with parts broken away, of a strip built up criss-cross stitch assembled multi-ply buffing wheel section; and
the stitching 4 may be supplemented by additional stitching as eriss-cross stitching 5, 6.
These strips, for such width as adopted, between the outer continuous plies 2 of the bufling wheel section, are preferably laid parallel as to a common plane and as to an adjacent plane at an angle or staggered relatively thereto. The bufling strips are preferably with the warp and woof on the bias at their marginal edge 7.
, This is also true of folded edge 8 (Fig. 3) wherein, instead of the material being cut on the bias, as in Fig. 2, the material in Fig. 3 may be continuous or with the strip of stock, and the pleating or reverse folding, to provide the edge 8, made at an angle thus forming folded bias edge 8 as exposed wearing edge at each side throughout the length of the strip material.
Insteadof the folded or reverse pleating type of edge 8, wherein thestock may abutin its bias or overlap to different extents or even have some clearance, there may be the I folded edge 9 of Fig. 4 produced by winding in building up the bufling wheel section of Fig. 1. As pleated, folded, or formed into a flattened helix, these straight strips each have two bias edges providing exceptional resistance qualities and also having the attribute of shrinkage neutralization when subjected to moisture. Due to the fact that this folded or flat helix type may be of continuous length, thereis advantage in such as a selvage or bias binding element.
In the assembly of these strips into buffing sections 1, such sections may be combined in the wheels 11 mounted on shaft 12 having flanges 13 with nuts 14 for clamping the sections 1 into the wheel 11. Bearings 15 sustain the shaft 12 which isto be driven by pulley 16.
Section assembly may be effected by radial stitching 17 or tangential stitching 18, or such spacings or combinations thereof as may 2 v mam be desired for a definite'degree of hardness,
speed or work. I
The strips when unfolded are limited in length to the distance across the material. However, these strips may he terminally trimmed by cuts 19, to form the strip sec tions, so closely approximating as assembled, the Wheel or disk contour as to practically eliminate truing and waste incidental there- 10 to. The strip cutting or forming and strip laying involves labor cost, but such is less than the Waste from sheet material of full disk cuttings. p
What is claimed and it is desired to secure is by United States Letters Patent is:
1. A buflin wheel section made up of plies said plies emlvodyin flattened helical strips providing parallel ias edges extending at approximately 45 to the strip edges.
20 2. A buflin wheel section made up of plies said plies em odying flattened helical strips providing parallel bias edges, and stitching lengthwise of the strip for maintaining the helix in the flattened shape.
, 25 3. A buffing section comprising plies em bodying flattened helical strips providing parallel bias edges, stitchin lengthwise "of the strip for maintaining t e helix in the flattened shape, and additional stitching 30 assembling the stitched helical strips as plies in a bufiing section.
4. A loufling wheel section made up of plies comprising strip portions having folded margins with the strip edges extendlng diagonaly therebetween in the direction of the strip extent.
' 5. A bufling wheel section made up of plies comprising strip portions lying parallel to each other in a common plane and having 1, folded margins with the strip edges extending diagonally therehetween in the direction of the strip extent.
In witness whereof I aflix signature.
