Harry E. Hargy, Sr., Sycamore l'lownsliip, 'j 1 lHamiltonCountmDhio I The present invention relates to buffing wheels and particularly to a wheel comprising a plurality of superimposed layers of flexible woven fabric having in it a series of regularly spaced and flattened radial pleats.
An object of the invention is to utilize a plurality of disks of woven material substantially equal in diameter to the finished wheel having formed in them a series of regularly spaced radial pleats which when placed about a common center and superimposed one upon the other provide a plurality of regularly spaced pockets in the peripheral working surface of the wheel.
Another object of the invention is to provide a bufiing wheel which has a minimum of material about its center whilst utilizing a greater amount of material in proportion as the distance increases from the center thereof thus effecting a greater saving of material in comparison with similar bufis heretofore employed.
A further object of the invention is toprovide a bufi composed of fabric disks having a multiple of centrally divergent pleats which when bound together produce a firmness to the wheel to the end that the thrust of centrifugal force is evenly distributed at the peripheral working surface thereof to accelerate and produce smoother buffing action and to consume less buffing compound hence a. saving of labor and compound.
Other objects will be apparent from the specification and drawing, in which:
Fig. l is a side elevational view of the finished buff, part of the outer covering being folded back to show the radial pleats.
Fig. 2 is a view taken on line 2-2 of Fig. 1 showing the plurality of pockets in the peripheral working surface of the buff.
Fig. 3 is a plan view of a fabric disk from which a pleated sector is formed. r
Fig. 4 is a perspective view of a pleated sector.
Fig. 5 is a plan view of the pleated sector in flattened position.
Fig. 6 is a perspective view of a modified form of pleated sector.
The embodiment of my invention consists of a buffing wheel 8 having a series of layers 9 composed of radially pleated sectors ill of woven fabric. I prefer to construct my buff by providing a disk H (Fig. 3) cut in the conventional manner from a suitable fabric. The disk has a radial slit # 2 to allow for its contraction into the flattened pleated sector Ill.
Fig. 4 shows the pleated sector in slightly extended position. The folds l3 producing the pleated effect radiate from a common center [4,
shaft (not shown).
whilst the substantially straight portions l5 between the folds are alternately twice the length of the remaining straight portions I6. It is obvious that when the sector (Fig. 4) is'in flattened position the folds will be in a common transverse 5 plane and form a number of regularly spaced pockets IT.
The pleating effect produced in the disk ll contracts it to a sector substantially one-third of the original circumference. It is therefore de- 10 sirable that three sectors placed around the common center It comprise one layer of the bufiing wheel. A number of such layers 9 superimposed one upon the other and given an outer covering 98 are held together by any numberor manner of stitching I9 depending upon the type of work for which the buffing wheel 8 is to be used. The wheel is then provided with a central annular opening to receive a suitable arbor or rotating Thus the completed wheel 0 presents a plurality of regularly spaced pockets at the peripheral working surface thereof which in use is capable of receiving and retaining a 7 maximum of bufiing compound with a consequent saving of the latter material. Also a distributed bias (indicated by numeral 2|) is produced in my sector of pleated fabric which imparts an even finish to the work subjected to the action of the wheel.
A maximum of the fabric is also presented at the periphery and decreases as its center is approached thus effecting a smaller waste of fabric at the unused central portions of the wheel. Also, due to the pleated effects, the stitching necessarily enters three thicknesses of fabric thus producing a firm bond between the sectors to offset the outward thrust of centrifugal force when the wheel is operating.
Fig. 6 discloses a modified form of my pleated disk wherein the pockets 22 are oppositely faced and alternately positioned. The folds 23 diverge outwardly to the periphery 24 from the common center 25. As in my preferred form a bias 26 is formed by this construction. The sectors formed from this construction are simi- 15 larly placed about the common center to'provide a plurality of superimposed layers to the finished wheel.
What is claimed is:
1. A bufiing wheel comprising a plurality of woven fabric disks, each disk having a radial slit and contracted into sectors of regularly spaced pleats having radial folds diverging outwardly from the center thereof. said pleated sectors being arranged about the center of the wheel in superimposed layers, and a row of stitching through said layers of pleated sectors, the wheel thereby presenting a plurality of regularly spaced pockets at its peripheral working surface.
2. A buifing wheel comprising a plurality of woven fabric disks, each disk having a radial slit and folded into a sector of regularly spaced pleats having radial edges diverging outwardly from the center thereof, said pleated sectors being arranged about the center of the wheel in superimposed layers to present regularly spaced pockets at the peripheral working surface of the wheel.
3. A buffing wheel comprising a plurality of woven fabric disks each disk being contracted into pleats having radial folds diverging outwardly from the center thereof, said pleated disks being arranged about the center of the wheel in superimposed layers.
4. A buffing wheel comprising a series of layers of fabric and each layer consisting of several sheets of substantially disk or semi-disk shaped fabric having therein a series of regularly spaced, flattened radial pleats to present a plurality of regularly spaced pockets at the peripheral working surface of the wheel.
5. A bufling wheel comprising a series of layers of fabric and each layer consisting of several sheets of fabric having a series of regularly spaced, flattened radial pleats.
6. A buffing wheel comprising a series of layers of fabric and each layer consisting of several sheets of substantially disk or semi-disk shaped fabric having therein a series of flattened radial pleats.
I. A buffing wheel comprising a series of layers of fabric and each layer consisting of several sheets of fabric having a series of flattened radial pleats.
