Application filed February 19, 1823. Serial No. 820,002.

To all whom it may concern:

Be it known that I, HARRY C. H. VVALsH, J12, a citizen of the United States, residing at Chicago, in the county of Cook 'and State of Illinois, have invented certain new and useful Improvements in Polishing Devices, of which the following is a specification.

This invention relates to polishing devices and has especial reference to devices of this character for polishing furniture, floors, trim and other highly finished wood work. I

One of the objects of the invention is to provide a device from which the polishing substance may be distributed on the surface to be polished thru a porous polishing medium.

Another object is to provide an inexpensive, etlicient and satisfactory instrument that may be made for hand operation or it may be made larger and operated by a pivoted handle.

Other and more specific objects and advantages of the invention will become readily apparent from a consideration of the following description when taken in conjunction with the drawings, wherein Fig. 1 is an elevation of one form of the device.

Fig. Fig. 1.

Fig. 3 is a section taken on line 3-3 of Fig. 2.

Fig. 4 is an elevation of another form of the device.

In all the views the same reference characters are employed to indicate similar parts.

The casing 5, to contain the polishing material, which may be a liquid, is provided with a base 6 having a part 7 extending beyond the casing to form a flangeto which the polishing sheet 8 is attached.

The sheet 8 extends beyond the flange and is the polishing medium. It may be a sheet of felt or other porous absorbent material to hold and distribute the material to be contained within the casing.

The base 6 contains one or more perforations 9, into the casing 5, which are normally covered with valve plates 10. The plates normally overlie and cover the respective openings 9 and thus close communication in-- to the casing.

The valve plates 10 are pivoted at 11 and are moved on their pivots by a reciprocating 2 is a section taken on line 22 of stem 12. The stem passes thru one end wall of the casing and a stufiing box 13. The outer end of the stem carries a presser button 14; by which to reciprocate the stem.

Pivoted to each plate 10 is a standard 15 thru the upper end of which the stem 12 passes and which is secured thereto by a screw 16.

A spring 17 presses against a collar 18 on the stem 12 and against the adjacentend wall of the casing to yieldingly hold the plates 10 in closed position. v

Pressure on the button 1 1 causes the plates to uncover the openings 9 and to permit the material in the casing to pass out into the polishing medium 8. When the button is released the spring 17 will return the plates to closed positions.

For polishing floors, and the like, a forked handle 20 may be fixed to each side of the casing, as at 21, to move the device over a surface to be polished. Mounted on the trunnion 21 is a rotatable wheel 22 and an arm 23. The wheel is held yieldingly against rotation by a spring 24:. The arm is slotted, at 25, to receive a pin 26 projecting from a reciprocatory rod 27 which is guided and supported by the strap 28. The rod 27 is bent to form an end member 29 which bears at 32 to the handle 20. A cord 33 is connected at 34 to the lever 31 and its lower end passes part way around the wheel 22. When the handle 31 is moved toward the hand piece 30 the arm 23 is drawn rearwardly thereby reciprocating 27 and 29, pushing the valve stem inwardly, opening the valves within the casing, and permitting the polishing material to be fed from the casing to the pad 8 in a manner clearly apparent.

The polishing device n'iay be moved back and forth by the handle 30 without moving the lever 31, when the pad has been sufficiently supplied.

Having described my invention what I claim as new and desire to secure by Letters Patent, 15:-

A polishing device. comprising a metal base plate, a relatively thick flat sheet of felt secured to the under side of said base plate, a liquid receptacle substantially U- shaped in cross section mounted on said base plate, the latter forming the bottom closure I for said receptacle, valves pivoted on said base plate and controlling openings therein to permit liquid to be discharged from receptacle into said sheet of felt, a valve stem extending; into said receptacle from one end thereof to control said valves, a spring in said receptacle to close said valve, a handle fixed to said receptacle, a spring retracted rotatable Wheel on said receptacle, a lever on said handle, a cord connecting said lever With said wheel to rotate the latter against H its spring tension, a slotted arm fixed to said Wheel, and a bent arm engaging the slot in said arm and said valve stem, whereby the valves in said receptacle may be controlled by said handle lever.

In testimony whereof I hereunto subscribed my name.
