. and I do hereby declare the, following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention relates to improvements in polishing belt machines. g

It has for its object to provide an improved machine ofthis kind which is of simple and compact construction and which includes means for removing the dust and dirt from the belt.

The invention consists in the features of construction and combinations of parts hereinafter described andspecified in the claims.

In the accom anying drawings, illustrating the. preferre embodiment of my invention: Figure 1 is a front elevation of a motor and two polishers mounted directly upon the Fig. 2 is an end elevation ofone of said polishing machines. Fig. 3 is a vertical section taken from front to back of thepolishing belt driving device. Fig. 4 is an enlarged vertical section thereof taken transversely, and Fig 5 is a View on line of Fig. 4 looking in the direction of the arrow.

Referring 1n oreparticularly to the drawings,

1 designates the motor and 2 the motor shaft. On the end of said shaft, as shownin Fi 1, is mounted the polishing belt driving wheel 3 which is partially inclosed by a housing 4. At one side said wheel has a flange 5 to which is secured an outwardly extending ring or plate 6 carrying the fan blades 7. The fan and that side of the wheel 3 are i'nclosed by the projecting housing 8. The-inner side of said wheel is closed by a flanged plate or casting 9 bolted to an arm 10 of the bed plate 11 To the inner surface of the peripheral por-v tion of the housing 4 are fastened. a plurality of vanes 12- extending across said housing and inwardly to within a short distanceof the polishing belt 13 which is passed overthe wheel 3 and a second wheel 14 mounted-the: requireddi'stance therefrom. The function of said vanes is to stop the dirt that is'thrown from the belt by centrifugal force.

Air enters the casing or housing'through through the small openings or slots 16 arranged opposite the vanes 12. The largevolume 0 air drawn in throu h said slot 15 by action of the fan bladesc eans the belt while the air which comes in through the small openings 16 removes the dirt from the vanes 12. The flared hood 17- which jects from the housing out over the elt serves to catch the dirt from the latter whereby it is brought under the influence of the suction created .by the fan and drawn into said housing.

The dirt removed from said ,at the outlet 19. 1 p I The great advantage in mounting the fan by made more compact and the fan is rendered more effective because it is brought nearer to the belt,

- I claim:

1. Thecombination, with a polishing belt, of a pair of wheels over which said belt is passed, a fan mounted on one of said Wheels and adapted to draw the dustfrom said belt, and a housing for said fan and wheel.

2. The combination, with a polishing belt, of a pair of wheels over which said belt is passed, one of'said wheels having aflange at one edge, a fan secured to said flange, and a housing for said fan and'wheel.

.3. The combination, with a polishing belt, of a pair of wheels over which said belt is passed, a fan mounted .on one of said wheels, a housing for said fan and wheel, and a flared hood on said housing extendingover the belt for the purpose specified. i

9. The combination, with a polishing belt, of a pair of wheels, over which said belt is passed, one of said Wheels having a flange at one edge, a fan secured to said flange, a housing for said fan and wheel, vanes secured to the inner surface of said housing and extending inwardly near to said belt, a flared hood fastened to said housing and projecting out over said belt, said housing having an openingin' one end and others opposite said vanes, and a door at the other end of said housing.
