It will be understood that tacle 10 or, as shown in 2.. a can 30. of wax the spring 17 is within the receptacle 10.

When waxing is to be performed, the device is moved back and forth on the surface to be treated, such as the floor 26. As long as the device is merely moved backwards and forwards, without any twisting motion on the handle, there is no relative movement of the contact member 25 and the receptacle 10. Assume, however, that the handle is twisted so that one side of the member 25 bears harder on the fioor than the other side and that the device is moved backwards or forwards. Under this condition the disc 19 will rotate relative to the receptacle 10. This will cause the rotation of the coil spring 17 since this spring is connected rigidly to the disc 19. If rotational movement cannot be obtained merely by excess pressure on one side, the whole device can be tilted as shown in Fig. 1. forms an angle with the floor, which angle is designated a in Fig. 1, this angle being exaggerated for sake of illustration. On tilting the device as shown in Fig. 1 and moving the device forwards, the spring 1'? will be rotated in such manner that the polishing wax Will be carried toward the opening 13 and may then be spread on the surface by means of the member 25. When the wax has been forced through the opening 13, the device is righted so that there is an even pressure on the disc 19 and thus the supply of wax stops and the wax forced through the opening 13 can be applied to the floor or other surface by merely moving the device back and forth. Even if the temperature is quite low, the spring 17 can be moved by twisting the handle to unloosen the Wax and work it down so that it will flow or move to the opening 13.

In order to still more facilitate the travel of the wax to the outlet opening of the wax container, it is preferable to provide the bottom of receptacle 10 with tangential guide slots 29 as shown in Fig. 3. These guide slots or notches 29 prevent the wax from merely sliding along the bottom of the receptacle. The Wax is pressed into the slots 29 by the reduced windings at the lower part of the spring and carried in the slots to the open: ing 13.

Fig. 4 shows a cover 33 for the Waxing device for closing the opening 13 when wax is not applied. The cover 33 is provided with a groove 32 adapted to receive spring-pressed balls 31 on the outside of disc 19. On slipping the cover over the bottom of the device, the balls 31 catch into groove 32 and thus the cover is held on. The cover may be, and preferably is, provided with bristles 34.- so that with the cover in place the device may be used for polishing the surface to be treated for the application of wax.

It will be understood'that one direction of movement is more advantageous in feeding the Wax than the other and the operator can readily determine which way to tilt the device to make the wax flow to the opening 13. It will be seen that the coil spring 1'7 acts like a screw conveyor to work the Wax to the outlet opening adjacent the floor.

While I have described a single embodiment of the invention, it will be understood that the invention may be embodied in a number of other forms.
