7 Claims.
This invention relates to bufiing, polishing, and abrasive wheels, and more particularly to an improved form of laminated bulfing wheel having interior ventilating pockets.
One object of this invention is to provide an improved buffing wheel of the above nature having a base strip, a top strip and a plurality of folded flat rolls or pads, disposed intermediate these strips and arranged to provide efiicient ventilation for the wheel, whereby the heat generated during its use will be rapidly dissipated.
Another object is to provide a bufiing wheel of the above nature in which each of the fiat folded rolls is constructed of alternate layers of crinkled paper or cloth.
Still another object is to provide a bufiing wheel of the above nature which will be relatively simple in construction, inexpensive to manufacture, easy to manipulate, compact, and very efiicient and durable in use.
With these and other objects in view, which will appear as the description proceeds, there have been illustrated in the accompanying drawings, several forms in which the invention may be conveniently embodied in practice.
In the drawings:
Fig. 1 is a face view of a bufling wheel embodying the features and principles of this invention, the outer layer being broken away to disclose the interior construction.
Fi 2 is a cross-sectional view of the same.
Fig. 3 is a development view of the first form of the invention, showing the relative arrangement of the single folded pads of fabric which are located between the surrounding base and topstrips.
Fig. 4 is an edge view of the same.
Fig. 5 is a face view of one of the cloth pads used in the arrangement shown in Figs. '3' and 4, as it appears before folding.
Fig. 6 is an edge development view of a modified form of the invention in which each pad has a double fold.
Fig. 7 is an edge development view of another form in which each pad is folded three times.
Fig. 8 is an edge development view of another modified form wherein each pad consists of a pair of layers of alternately disposed crinkled paper and cloth.
Fig. 9 is a face view of one of the pads used in the form shown in Fig. 8, a portion of the crinkled paper being broken away to show the bias cut fabric therebeneath.
Fig. 10 is an edge development view of still another modified form of the invention wherein the pads are arranged in overlapped relation between the top and base strips.
First form Referring now to the drawings wherein refer- 5 ence numerals designate like parts throughout the several views, in the first form of the invention as illustrated in Figs. 1-5, the numeral Ill denotes an elongated base strip of sheet materiaLpreferably of cloth cut on the bias, and being 10 of'proper dimensions .to correspond with the size ofthe. buifing' wheel to be formed therefrom. A plurality of flat pads, l I, folded crosswise to the base strip 10 from sheet material, preferably cloth cut on the bias, are laid side by side upon the. base strip ill with the edge l2 of each one abutting the edge I3 of the next adjacent one, said: pads being coextensive in width with the base strip 10, whereby their ends M and I5 will be substantially-in alignment with the respective side edges of the strip III.- Each of the pads ll of the form shown in Figs. l-5 isformed by folding a short piece of cloth crosswise along the dotted'line 16. This provides two loose free -ends at the padedge 12, and a single folded end at theedge l3.
After arranging the pads H upon the base strip Iilin the manner indicated in the development View of Fig. 3, a topstrip of sheet material I1,
. also preferablyof-cloth, cut on the bias, is placed thereover, and-the entire assembly will be rolled into cylindrical shape about a slotted drum, not
shown, the center being thereafter drawn inwardly by a cord l8 to produce a disc-shaped wheel, as=fully described and shown in our previens-Patent No. 2,209,089, issued July 23, 1940. The buffing wheel, thus formed, comprises a flat laminated disc composed of a plurality of layers of cloth which are puckered together about a hubportion l9 surrounding a central shaft receiving. opening 20. The layers of cloth are then stitched along circular parallel lines 2| and 22 about the shaft opening 20. It will be understood that spira-l stitching may be employed, if
desired, within the spirit and scope of the invention,
In thecompleted bufiing wheel, as shown in Figs. .1. and 2, it Will be noted that the pads II and base and top strips -0 and I1, respectively, have been folded along a circular line to bring their side edges into parallelism. The base strip II) will form outer covers 23 and 24, a double thickness central partition 25 will be formed by the top strip l1, and a series of circumferentially abutting pad portions 26 and 21 between the central partition and the outer covers 23 and 24. Radially disposed wheel ventilating pockets 28 are thus formed by the above construction which will assist in the rapid dissipation of heat from the self-cooling bufiing wheel when it is in use.
Modified forms To provide a wheel of greater thickness than that of the first form, a modified form is shown in Fig. 6 in which a plurality of double-fold intermediate cloth pads 30 may be formed from a longer strip of material than in the first form,
and which pads are folded twice, as indicated in Fig. 6. Each pad 30 will thus present a pair of loose ends 3| and 32, a single-ply folded edge 33, and a two-ply folded edge 34 at the adjacent abutting pad 30 when the pads are arranged on a base strip 35 and finally covered by a top strip 36.
In Fig. '7 a wheel of still greater thickness is disclosed, each pad 31 being folded upon itself three times, whereby said pad 31 will present a four-ply folded edge 38, a pair of loose ends 39 and 40, a single-ply folded edge 4|, and a two-ply folded edge 42, when they are assembled between a base strip 43 and a top strip 44.
In the form of composite buffing wheel, shown in Figs. 8 and 9, a piece of cloth and a piece of crinkled paper 5|, are used to form each of the composite pads 52. The piece of crinkled paper 51 is laid upon the piece of cloth 50, and the two layers are folded together crosswise on the dotted line 53 (see Fig. 9), with the crinkled paper on the inside. Two successive folds are then made in the paper and cloth assembly whereby each flat pad 52 will present a pair of free juxtaposed interior paper ends 54 between a pair of free cloth ends 55 and 56, a two-ply paper and folded edge 51, and a four-ply fold 51a consisting of two plies of paper and two plies of cloth, said pads being assembled between a cloth base strip 58 and a cloth top strip 59.
The modified form in Fig. 10 comprises a plurality of single fold cloth pads 60 identical with the pads H of the first form (see Figs 4 and 5), both with their loose free ends 6| slightly overlapping the adjacent two-ply folded ends 62 of the next adjacent pads 60. Such a structure will provide somewhat larger air pockets between the cloth base strip 63, the cloth top strip 64, and the pads 60, due to the space required for the overlapping ends.
An important advantage of all forms of the present invention is that the unconnected pads provide air pockets which rapidly and efficiently dissipate the heat developed during the buffing operation.
' While there have been disclosed in this specification several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosures, but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
Having thus fully described the invention what is claimed as new and for which it is desired to secure Letters Patent, is:
