This invention relates to an improvement in floor polishing machines, and is a continuation in part of my co-pending applications Serial No. 661,424, filed Sept. 7, 1923,

The object of the invention-is to provide for an even distribution of polish over the surface being treated by discharging the polish from a container upon the polishing media, which in turn distributes it over the surface. The olish is preferably contained in cans remova 1y held in the center of a polishing brush, and discharge orifices are so arranged in the cans that upon rotation of the brushes and cans about a vertical axis the centrifugal force discharges the polish laterally upon the bristles of the brush or other polishin media, from where'it is fed onto the floor eing treated. This centrifugal force is created by the rotation of the containers about their individual axes while in turn moving all of the containers in a planetary movement about a central axis. In this way the rotary members which carry the wax containers travel in an orbit about a common center, while those containers in turn are rotated in a direction opposite to that of the movement of all of the containers, discharg- 80 ing the wax laterally against the wall formed by the rubbing means.
In the accompanying drawings: Fig. 1 is a sectional view partly in side elevation through the machine; 36 Fig. 2 is a horizontal sectional view thereo g 'lig. 3 is a plan view of one of the brushes; an
Fig. 4 is a sectional view through the same. In the form of the invention here disclosed, a main housing 1 is provided and rotatably supported upon rollers 2 in order to move the machine over the surface being treated. An upper housing 3 is mounted upon the housing 1, these two housings forming the '5 to raise and lower frame of the machine. In the top of the housmg 1, a bearing 4 is provided and a verticalshaft 5 extends through this bearing being rotatably mounted therein. A shifting lever 7 is connected with the upper end of the shaft the same through the bearing 4. nut 8 is threaded onto the shaft 5 and a spring 9 is interposed between the nut and the bearing 4 normally tending to force the shaft downward, the tension of this spr ng being adjusted by the nut 8. A spider 10 1s fixed to the lower end of the shaft 5, and a spring 11 is interposed between the nut 8 and this spider, said spring being of less resiliency thanthe sprin 9.
The spider 10 has radiating arms 12 extending outwardly from the center thereof, and stub shafts 13 are fixed in the outer ends of these arms, said stub shafts each carrying a pinion 14, meshing with a ring gear 15 fixed within the main housing 1. Connected with the inions 14 to be rotated thereby are brush hol ers 16 supporting brushes 17 which may be of the general form shown in Figs. 3 and 4 and having an opening 18 through the center thereof for removably receiving a wax container 19. This wax container is provided with. radially arranged orifices 20 located near the bottom and in the peripheral wall thereof. As shown in Fig. 4, the wax container is deeper than the back of the brush so that the orifices 20 are located beneath the same and in position to discharge the wax laterally against the surrounding wall of bristles or other rubbing means 21.
The shaft 5 is rotated by means of the gear 22 fixed thereon and meshing with a pinion 23 mounted on a stub shaft 24 which also has a gear 25 keyed thereto and meshing with a pinion 26 on the motor shaft of an electric or other motor 27 mounted upon the upper casing 3. This gearing reduces the speed from the motor to the drive shaft 5 to the desired extent, and forms a driving connection face of the floor.
therebetween for im artin rotary motion to the drive shaft and t e sgi er 10. As rotary motion is t us supplied to the spider, it will rotate about the axis through t e shaft 5 carrying the stub shafts 13 therearound an causin a rotation of the pinions 14 b contact wit the ring gear 15. The spee of the machine causes the centrifugal action thus created within the wax containers 19 and by the rotation thereof to discharge the wax laterally through the orifices 20 onto the wall of the bristles 21, which surround this wax container in the brush, and the bristles in turn evenly spread the wax over the surface-being treated. The central opening through the brush permits of removal an replacement of the container as it is emptied of its wax, and also provides for the discharge of the wax onto the wall of the surrounding bristles for even distribution over the sur- These wax containers being rotated about vertical axes and the bristles extending in directions parallel to said axes, the wax will bedischarged laterally onto said bristles by the centrifugal force caused by the planetary rotation of the brushes and containers, and in this way an treated is obtained.
claim 1. The combination with a plurality of rubbing members having rubbing media connected therewith, contamers connected with said rubbing members for dischargi-n the contents thereof laterally onto the ru bing media, of means for rotating the rubbing members in an orbit about a common center and simultaneously about individual axes.
2. The combination with a plurality of onto the surface of the surrounding wall of bristles, of means for rotating the brushes in an orbit about a common center, and simultaneously rotating, said brushes about individual vertical axes for discharging the contents of'the containers by centrifugal force laterally onto the surfaces of the surrounding walls of bristles for distribution over the surface being treated.
4. In a floor polishing machine, the combination of 'a casing, la-imlrlflurality of rubbin members carrying po applying media an even distribution of wax over the surface behaving wax containers connected therewith,
said containers having discharging orifices discharging the contents of the containers by centrifugal force laterally onto the polish applying media for distribution over the sur face bein treated.
In -testimony whereof I afiix my si nature.
