Abstract
DRUM FOR SANDING BELT
ABSTRACT OF THE DISCLOSURE
A drum adapted to be coupled to the chuck of a hand drill for mounting a sanding belt for rotation.
The drum is of one-piece construction and has a cen-tral, imperforate web integral with flexible flanges on the outer periphery of the web. The web and flanges are formed from a resilient material, to that the web can expand or stretch and the flanges can flex under centrifugal force to increase the frictional engagement between the web and flanges and the inner surface of a sanding belt on the drum. In one form of the drum, the flanges have a pair of continuous ribs at respective side extremities thereof. This drum is adapted for use with a cylindrical sanding belt having a pair of axially spaced annular shoulders on the inner surface thereof, the ribs being adapted to engage the shoulders to prevent axial movement of the belt on the drum. Another embodiment of the drum is free of such ribs and is adapted to be used with a sanding belt which may have abrasive on both the inner and outer surfaces thereof.

Description
This lnvention relates to improvement in the mounting of sanding bel-ts for rotation and, more particu-larly to an improved drum for coupling a sanding belt to a drive motor, such as a hand-hel~ drill.
Rotary drums for sanding belts have been used in the pa~t but, Eor the most part, they are made up of several parts and require assembly which adds to production costs.
Also, a major drawback of drums previously made for this purpose is the relatively short operating life, requiring replacement and adding to the overall cost of sanding operations. Because of these drawbacks, a need has arisen for an improved drum for sanding belts wherein the drum is of simple and rugged construction, has a long operating life, and can be produced at minimal cost.
The present invention satisfies the aforesaid need by providing a drum of a one-piece construction. The clrum is formed from a moldable, resilient material which has a long useful operating life and does not need replacement except at relatively infrequent intervals.
To this end, the drum comprises a central, imper-forate web integral with a pair of outer peripheral flanges provided with a cylindrical outer surface. The drum is formed from a resilient material, such as natural rubber, so that, when the drum is rotated at a high speed, the web will expand or stretch radially outwardly and the flanges will - flex radially outwardly under centrifugal force. This will cause the web . .

18 A first embodiment of the sanding belt drum of I9 th~s invention i~ broadly denoted by the numeral 10 and i5 shown in Figs. 1, 2 and 5. Drum 10 is formed from ~ resilient 21 ~aterial and compr~se~ a circular, flexible, imperforate 22 central web 12 and a pair of ~lexible outer peripheral 23 flanges 14 integral with web 12 so that drum 10 is of a one-24 piece construction. The web and ~langes are preferably formed simultaneou~ly in a molding process. The web is of a 26 thin wall eon~truction and, a shown ln Fig~, 2 and 5, i~
27 provided with a pair of bosses 16 at t~e center thereof for 28 support purpo~e~. The bos~es pro~ect laterally from opposite 29 sides of the web. ~hile Fig. 5 ~how~ ~he sides of the web parallel with each other, they could be tapered from the 31 ~enter outwardly with the thlnne~t part near the outer 32 periphery the web to provide additional ~upport.
~ .
A pin 18 extends through the boss and the web as shown in Figure 2. Thus, a chuck 20 on a hand drill or the like can grip the pin for rotating drum 10 about the central axis of web 12.
Flanges 14 have cylindrical outer surfaces and project laterally in opposed directions from the outer periphery of web 12 as shown in Figures 2 and 5. The flanges have respective integral ribs 22 at their outer extremities. These ribs are formed with the flanges in a moldir.g process. The flanges have a thin wall construction and, because they are resilient, they are essentially flexible so as to flex radially outwardly when subjected to centriugal force. Similarly, web 12, being of a thin wall construction, and formed from a resilient material can - ;
; 15 expand or stretch radially outwardly under centrifugal force as drum 10 is rotated at high speed, such as 2200 rpm or the like. This assures a positive frictional engagement between the web and the flanges and the inner surface of a sanding belt mounted on the drum for rotation.
For additional holding capabilities, ribs 22 are provided for use with a sanding belt 24 (Figure 6) which -~
comprises a band 26 provided with annular shoulders 28 on the inner surface thereof at locations spaced inwardly from the opposed sides thereof. These shoulders can be formed by securing a band to the inner surface of band 26 with the inner band having an axial length less than that of band 26.
- Shoulders 28 abut ribs 22 in the manner shown in :
Figure 5 when band 26 is mounted on flange 14. Thus, a tendency for -the belt to move axially of the drum is coun-tered in two ways, first by the frictional engagement be-tween the flange and the inner surface of band 26 and, secondly, by -the stop feature provided by the engagement of ribs 22 with shoulders 28.
Drum 10 has the following typical dimensions:
Maximum diameter of about 3.80 inches, web thickness of about .25 inch, total axial length of flanges 14 of about 1.40 inches, and angle a (Figure 5) of about 5. The material of drum 10 is typically 55 Durometer natural rubber but can have a hardness in the range of 45-65 Durometer.
In use, pin 18 is secured in the conventional manner to chuck 20 and sanding belt 24 is then placed on the drum and seated on the flanges 14 in the manner shown in Figure 5. Then the hand drill associated with chuck 20 is actuated to rotate drum 10 and thereby permit the sanding of a surface by the outer surface of band 26 which is pro-vided with an abrasive in the usual manner. During the sanding operation, web 12 will expand radially outwardly and flanges 14 will flex outwardly yet web 12 will generally maintain its disc-like shape since it is rotating in its own plane. There will be no circumferential movement of band 26 relative to flanges 14 during rotation of drum 10 because of tha frictional engagement of web 12 and flanges I4 and the inner surface of band 26. Moreover, this frictional engagement plus the stop action afforded by ribs 22 will prevent any substantial axial movement of band 26 relative to flanges 14.
1~ 112a5 I Fig. 3 L11u:trates snother embodiment of drum 10, 2 namely drum lOa. This drum ls subs~antially the same in all 3 ~ respects as drum lO except that drum lOa has no ribs 22, 41 Instead, dr~m lOa has a completely cylindrical outer surface and is adapted for use wl~h a sanding band 24a which may 6 have abrasive on both i~s inner and outer surfaces. AbraRive 7 need not be on the inner surface and, if used, i~ need not 8 cover the en~ire inner surface as shown in Flg. 4, If used, 9 however, ~he abrasive on the inner surface provides greater frictlon between the drum lO and the sanding belt. Without Il the abrasive on the inner surace, there will be suf~icient 12 friction between the ~lange of drum lOa and the inner surface 13 o sanding belt 24a because of the expan~ion or stretching 14 of the central web of dru~ lOa and th~. flexing of outer peripheral flanges due to centrif.ugal force, thereby cau~ing 16 the web and flanges ~o be pressecl with greater force against , 17 the inner surface of the sanding belt to achieve an increased 18 frictional force.
19 Although the foregoing invention has been described 20 in some detail by way of illustration and example for purposes .
21 of clarity of understanding, it wlll be obvious ~ha~ certain 22 changes and modifications may be practlced within the scope Z5 of the app Ided claims.
