13 Claims.

The present invention has to do with a wax spreading and floor polishing device.

The objects of the invention include a simplifled structure for a polishing device suitable for manipulation from a standing position; a new and improved structure for a device adapted to hold a pad to spread wax evenly over a floor or other surface; and new and improved means for attaching a handle and a polishing pad to a waxing apparatus.

These objects, and such other objects as may hereinafter appear are obtained by the unique construction, improved combination, and novel arrangement of the several elements constituting the invention, one form of which is illustrated in the accompanying drawing, in which:

Figure 1 is a plan view of a device embodying the subject matter of the invention;

Figure 2 is a central section taken transversely of the device shown in Figure 1; and

Figure 3 is an end elevation of the device shown in Figure 1 with a pad attached thereto.

Like reference characters are used to designate similar parts in the drawing and in the description of the invention which follows.

Weight is considered essential in a successful wax spreading and polishing device. The present invention comprises a relatively heavy base or frame III which may be of heavy iron or sheet steel. The weight desired will govern the thickness of the material. At opposite sides thereof are upstanding flanges II and I2, the character of which is definitely set forth in Figure 2. The inner wall of said flanges is grooved as shown in Figure 2.

In order to permit the operator to have easy access to the pad holding and releasing members, the opposed ends, preferably, of the flanges H and I2, terminate at a point or points removed from the end edge of the plate Ill.

At the center of the device, two or more tongues l5 and 16 are bumped up. The bumping tool or device may impress the material of the base in a manner to produce a figure like that shown in the dotted outline ll of Figure 1.

Spring means are provided for holding the pad in operating position with respect to the plate Ill. The spring means comprises parallel leg portions adapted to be resiliently pressed into the opposed end flanges II and I2 of the plate and to be held therein by the resiliency of the spring means. This spring means preferably comprises a single piece of wire having free ends provided with finger holds or grips for distorting or pressing the free ends inwardly so as to release the spring legs from the flange portions of the plate, thereby releasing the pad from the plate proper.

In the present embodiment of my invention, I have illustrated the spring means as comprising a spring l8 having ring ends I9 and 20 and preferably of an S shape. This spring means is disposed intermediate the flanges H and 12 so that the two opposed legs of the spring means are lodged in the grooves of the flanges H and I2. The central section 2| of this spring is disposed beneath the tongues l5 and I 6, which tongues point in opposite directions. The tongues are turned down upon and over section 2| of the spring l8 firmly to secure the spring H3 in assembly with the base H).

For attaching a handle shown fragmentarily, there is supplied a socket 22. Said socket has an end section 23 extending about section 2| ofthe spring l8, the spring l8 forming a pivot for angular movement of the mop handle to adjust itself to the requirements of the user of the device.

In use, a pad 24 having end extensions 25 and 26 is disposed under the plate with the body of 3 the pad resting flatly upon the underside of the plate and with the ends 25 and 26 extending over the flanges H and 12. To secure the extensions 25 and 26 in position, the spring I8 is manipulated, generally, first at one side, and then at the 1 other side by the use of the finger sections 19 and 20.

By these grip pieces, the end sections of the spring may be drawn towards the center of the plate and away from the flanges II or l2 as the case may be, to allow the insertion of a flap 25 or 26 upon the grooved interior periphery of the flange, after which the spring I8 is released to grip the extension 25 or 25 of the pad 24 and to maintain the pad in close physical contact with the flange of the plate.

The cut-away sections l3 and I4 of the flanges H and I2 are to provide room for the ready use of the finger pieces I9 and 20. In forming the tongues I5 and IS, the material may be dea pressed therebetween to facilitate the attachment of the socket 22.

The pad may be of lambs wool, cloth, or any other suitable material. It is saturated with wax and moved across a floor or other surface to be polished. When the pad 24 is worn out, it is readily removed by gripping the spring first at the finger piece l9 and then at the finger piece 20 to release the extensions 25 and 25 of the pad.

When desired, additional tongues or lugs may Y be provided for holding the section 2| of the spring member, these being indicated by the numerals 30 and 3|. Generally they are opposed in direction and. are formed by suitable tool work upon the member ID.
