1 Claim.
This invention relates to polishing wheels and is especially useful in the polishing of flat surfaces.
Objects of the invention are to provide a succession of cushioned polishing members for engaging the work, to .provide renewability of the polishing surfaces, and to provide spring support for the polishing members.
These and other objects will appear from the following description and the accompanying drawings.
Of the drawings:
Fig. 1 is an end elevation, partly broken away and in section showing the invention in one of its forms,
Fig. 2 is a cross-section thereof taken on line 2-2 of Fig. 1,
Fig. 3 is a detail sectional view thereof taken on line 3-3 of Fig. l,
Fig. 4 is a view similar to Fig. 1 showing another form of my invention, and
Fig. 5 is a longitudinal sectional View thereof, taken on line 5-5 of Fig. 4.
Referring to the drawings, and rst to Figs. 1 to 3 thereof, the numeral I0 designates a shaft about which a tubular driving support Il is rotatably mounted, as on ball bearings I2, I3 and I4. The shaft Ill is xed to a stationary arm I5. The support II has a sprocket I6 fixed thereto for driving it.
The tubular support I I has a ange Il fixed to one end thereof and a similar ange I8 is removeably mounted on the other end thereof where it is held against axial movement by a fixed shoulder I9 and a collar 2Q, the collar having threaded engagement with the tubular support.
Flanges I 'I and I8 have aligned apertures 2|, 22 -at spaced-apart positions thereabout for rotatably supporting a plurality of rods 23 arranged parallel to the shaft IIJ.
Each rod has fixed thereto a polishing member 25 having limited swinging movement with its rod and member extending therealong. Coil springs 26, 21 seated in radial sockets of flanges I8, I1 respectively impinge against the polishing members 25 and force them radially outward while L-shaped rods 28 fixed to the polishing members engage under the next successive rods and limit outward movement.
Each polishing member supports a strip of flexible sheet abrasive material 35, such as emery cloth, sandpaper, or the like which is fixed to the rod 23 as by a clamp bar 3| held in place by screws 32, the abrasive strip being secured only at one edge and extending freely along the outer face of the polishing member.
For cushioning the abrasive strip, a pad 33 of resilient rubber-like material such as soft vulcanized rubber, synthetic rubber or the like is fixed to the polishing member 25 by a vulcanized bond and underlies the abrasive strip.
In use, the polishing members are forced outwardly by the springs 26, 21 and also by centrifugal force, and the abrasive strips are pressed against the work and cushioned by the cushions 33.
Referring to the form of the invention illustrated in Figs. 4 and 5, a stationary shaft 50 rotatably supports a tubular support 5| which is rotatably mounted thereupon by ball-bearings 52, 53. The support is adapted to be driven by a sprocket 54 xed thereto.
The support 5I has a fixedflange 55 at one end thereof and a removable iiange 55a at its other end. Flange 55a is secured thereon between a fixed shoulder 55 and a collar 51 screw-threaded to the shaft.
For tensioning the bands about the polishing members While urging the .polishing members radially outward, a rod 'I0 is provided and extends parallel to the axis of the shaft 50. Leaf springs 'II have one end secured to the tubular support 5I and the opposite end secured to the rod 10 to urge it toward the polishing element. One rod 'It is provided at each cushioning pad.
In use the endless bands of abrasive material are held against excessive slipping about the polishing members by pressure of the rods 'I0 thereagainst while the' springs 'Il also urge the polishing members outwardly against the work assisted by centrifugal force. Outward movement is limited by the slots 64, 65 in which the ends of rods 62 are located.
Variations may be made without departing from the scope of the invention as it is dened by the following claim.
I claim:
A polishing wheel comprising a rotatable support having spaced apart radial anges, one flange being removably secured thereto, said anges having aligned apertures therethrough at spaced apart positions thereabout, rods pivotally retained in said apertures, each rod having a relatively stiff .polishing shoe secured thereto and adapted to swing arcuately thereof, a pad of resilient rubber-like material secured to said shoe for supporting and cushioning a strip of abrasive sheet material, spring means for urging said shoe 4 outwardly, and means for limiting movement of said shoe, said spring means including means for retaining said abrasive sheet material on said shoe.
URBAN C. HAREN.
