mmw R8 1 F. L. YERGES BUFFER Film June 4. 1923 GIT BUM a appilication filed June a, 1. serial 1th. eaaass.
To all whom it may concern: 1
Be it known that l[, FRANK L.
a citizen of the United States of residing at Fremont, Sandusky Ynncns, America, County,
5 Ohio, have invented new and useful Buffers,
of which the following is a specification.
This invention relates to bufling or working materials, more particularly for the final shaping or finishing of metallic bodies.
This invention has utility when incorporated in a bufiing disc or wheel structure.
Referring to the drawings Fig. 1 is a side elevation of an embodiment of the invention in a buder structure 15 for a more firm or hard usage, parts being broken away;
Fig. 2 is an embodiment of the invention in a bufi'er section for a loose head;
Fig. 3 is a partial section of the buffer sections as grouped in a complete bufler disc or wheel; and
Fig. 4 is an embodiment on a reduced scale, of a pair of bufier or grinding wheels as assembled for use.
Disc 1 is of fabric, say woven stock, as white cotton duck, and may be concentrically assembled in slightly angularly shifted positions as to the weave direction thereof and interposed, say intermediately 0 of such group of plies; there may be a somewhat shorter radius fabric disc or pl 2 of impregnated material as a lubricant or the disc plies. These plies as laid together with a common central opening 3 for mounting upon a shaft, are shown as having chord stitches 4:, 5, assembling such plies into a section 14 as a sort of quilt to form pockets between said plies. Said stitches are herein shown as in parallel relation in two series and the structure thus produced is of the hard head type of bufi'er section 14. These pockets embody parallel series both as formed between adjacent plies, and as to pockets on opposite sides of an intermediate ply of the section. Inner pockets of a radial series are closed or buried to be opened by wear of the buffer periphery thereinto.
For the loose type of buffer section, there is centrally 0f the disc fabric 1, 2, a single stitching 6 once about the central opening 3.
In ractice, the several bufier sections 14 to a epth or thickness as desired, may be mounted on a shaft 7 and clamped in firm relation by nut 8. Such groups of bufier sections 14 as forming disc wheel -9 assembled on shaft 7 may be rotated at high speed. To this end the shaft 7 is mounted in bearmgs 10 carried by the standard 11 and driven at high speed by pulley 12 as actuated by the belt 13.
ssummg the section 14 to be built up of say nine plies of fabric, there maybe four plies 1 on each side of the intermediate ply 2, assembling such in a single section 14. This ply 2 of fabric herein being of similar material to that comprising the plies 1 is preferably impregnated with a lubricant, as wax or reducing the drag in the operation, it has been found paraffin is a very deslrable ingredient for this impregnating material. However, paraflin of itself has not the adhering qualities in assembly with the structure which it is desired to have and which is obtained'by melting with this paraffin a small quantit wax, having a me ting point of approximately 196 Fahrenheit and the melting point of the parafin being much lower, say 102 Fahrenheit, a compound found acceptable has a melting point of 123 The paraffin in operation in this composition is accordingly more readily fused or melted as a lubricant for the stock long before material heating of the bud'er disc occurs, and accordingly there is a great reduction of fire hazard from the operation of the buffer hereunder. At the high speed of operation of the loose head section of Fig. 2, this lubrication feature is of utility and in the practice as developed hereunder, the frequency of occurrence of the impregnated disc ply 2 may just compensate the proper lubrication of the units in the wheel for buffing or other operation as well as to act on the stock that drag is avoided, even with aluminum.
Where the more arduous work of builing, say when tripoli, rouge, lime, or even emery, is used therewith, the harder head disc wheel of Fig. 1 is the preferred form. As herein disclosed, this disc wheel of Fig. 1 is one which ma be started for its operation, immediate y it is put into use, the wheel of itself having the proper finish for at once taking up the work and the lubricant plies 2 being far enough in the head so that in appl ing the work, the warmth of the generate heat may dissolve or melt the lubricant and be gradually fed out to the working region in a way that will not of beeswax. The beesonly lower the but also permit applied material temperature from friction a better adherence of the to effect the polish, grindin or other finishing operations.
lurthermore, the grouping arrangement of this disc wheel structure is one again assistin in this holding, not only of the lubricant, ut also of the applied material, for the intersecting chords 4, 5, of the stitching as assembling the plies into the respective sections provide pockets which to all intents and purposes herein are uniform into the peripheral extent of the several disc sections 14; As the threads run out on the periphery of the SBCtlOIlS thGl'G is not disturbance of this uniformity by these threads. They do not approximate the periphery to give a hard region. Furthermore, the several disc sections 14 are, in themselves alternated, one as .the bu to the other as shown in the broken away portion in Fig. 1 showing parts of three sections. It is accordingly seen that not only the warp and woof directions of the successive plies 1 of fabric are angularly shifted as to each other but with successive assembled sections 14' oing into the wheel 9, the are also angular y shifted so that the stitc lines, 4, 5, are also angularly shifted as to each other. These are material factors in ereatin a uniform head or working face for er discs and as operating herein the lubricant and these pockets for holding not only the lubricant but the abrasive, there is a most material economy in operation not only as to power required for running the buffer with a given pressure applied on it with the given work thereto, but also in the life of the disc wheel in accomplishing a greater work in a better manner in a less riod of time. The abrasive may be applied to the wheel by1 dusting thereinto; by holding a block of t e abrasive against the wheel; by rolling the wheel in the abrasive; by incorporating the abrasive in the wheel or section assembly.
Each disk or ply is a sheet one or more pieces of material in to form a layer. The stitching assembles a plurality of these plies to ether as a section, and also assembles such phes as may not be in one piece of material to form from such pieces a plain disk element in said section so that the section as assembled comprises plain disks independently of folds or lapping of the material back upon itself. The stitching as running out on the working face,'wh1le variously spaced, is in a given working periphery of the section approximately uniformly distributed for such particular working periphery of the disk. This groupin of not folded or flat layers of material wit stitching running out in periphery stabilizing proximity produces a section of this buffer wheel as compri'singplain disks with substantially uniformly distributed stitching.
What is claimed and it is desired to secure by Letters Patent is:
1. A buffer wheel comprising a plurality of plies of plain fabric disks secured to eac other by lines of stitching substantially uniformly distributed over the working area thereof to form circular series of pockets successively opening to the periphery as the wheel wears away.
2. A buffer wheel comprising a plurality of lies of plain fabric disks secured to each other by intersecting lines of stitching substantially uniformly distributed over the working area thereof to form closed pocke s successively opening to the periphery as the wheel wears away.
3. A bufier wheel comprising a plurality of plies of plain fabric disks secured to one 1 other b intersecting series of parallel lines of stitc ing uniformly distributed over the working area thereof to form pockets successively opening to the periphery as the wheel wears away.
4. A buffer wheel comprising a plurality of plies of lain fabric disks secured to each other by intersecting series of uniformly spaced lines of stitching forming pockets successively opening to the periphery as the wheel wears away.
5. A buffer wheel comprising a plurality of plies of plain fabric disks secured to each other by intersecting series of uniformly spaced parallel lines of stitchin forming pockets distributed over the wor ing area thereof and successively opening to the peri hery as the wheel wears away.
11 witness whereof I afiix my signature.
