Application May 11, 1936, Serial No. 79,117 1 Claim. , (01. 51-263) 5 This invention relates to automatic polish feeders and has for the primary'object'the pro~ vision of a device which is especially adapted for the tube 5 and to a tube l5, and the latter is in turn connected to the outlet iii of a compressor _ i'l mounted on the base I. A drive shaft I8 is - ef?ciently distributing abrasive to a lens polish ing tool or machine or for any other purpose wherein it is desired to have abrasive spread on is connected to an electric motor 20 mounted on the base and equipped with a rheostat 2| for a surface. , With these and other objects in view this in ventionconsists in certain 'novel features of con 710' struction, combination and arrangement of parts ‘ For a complete understanding of my invention, reference is to be had to the following descrip '15 tion and accompanying drawings, in which Figure 1 is a side elevation partly in section illustrating an automatic polish feeder construct ‘ ed in accordance with my invention. Figure 2 is a top plan view illustrating the 20 same. Figure 3 is a diagrammatical view illustrating a series of feeders operating from a single com pressor; and ' r v ' Figure 4 is a detail sectional view illustrating the adjustable mounting for the brush. Referring in detail to the drawings, the nu meral l indicates a suitable base on which is mounted a vertically arranged standard 2 carry ing a tank or reservoir 3 for containing abrasive 30 and is provided with an outlet valve 4 to which is connected a ?exible tube 5. A distributing brush iiv consisting of a brush head '1' carrying bristles 8 and a handle 9 is molded to the head.~ The handle 9 is engaged 35 by an adjustable clamp l0 having a swivel con nection II to the base i whereby the brush may be moved or arranged in several adjusted posi tions so as to contact with a surface. Mounted in the head 1 of the brush is a tube l2 one end 40 the purpose ofre'gulating speed of rotation of the motor. shaft A ?y wheel 22 is secured to the drive I8. ' ‘ j 7 After the brush 6 has been adjusted to a sur to be hereinafter more fully described and V face, the valve 4 is'opened to permit the abrasive claimed. 2 geared to the compressor, as shown at !9, and of whichrterminates within the bristles 8 while the other end extends outwardly of the head and is connected to a ?exible tube I 3. _A'Y-shaped coupling I4 is connected to the tube. l3‘ and t0 of the tank 3 to pass into the Y M. The com pressor l1 driven by the motor 20 forces air into the coupling M which mingles with the abrasive and forces the latter between the bristles of the 15 brush onto the ‘surface. The compressor l1 isv of the type having a reciprocating piston (not , shown) so that the'air expelled therefrom will be intermittent to the coupling l4 thereby eject ing the abrasive through the brush onto the sur face with intermittent impulses. _ A device constructed in accordance with the foregoing will e?iciently distribute the abrasive onto a surface, such as 'a grinding‘ or polishing element of a lens polishing machine or tool and 25 obviates the customary practice of manually plac ing the abrasive on a surface by a brush operated manually. If desired, a series of abrasive dis tributors constructed in accordance with the foregoing may be operated from a single com pressor, as shown in Figure 3. a What is claimed is: An automatic polish feeder comprising a base, a fountain type brush adjustably mounted on the base, an abrasive supply tank carried by the 35 base, an outlet valve for said tank, a power driven compressor mounted on said base, ?exible tubes connected to said valve, compressor and the brush, and a Y-shaped coupling connecting the tubes whereby the contents of the tank may com mingle with, air from the compressor and be forced by the air through the brush.
