Referring to-the accompanying drawing.
the polishe'r of the present invention consists of an elongated handle 1, a substantially flat head 2 attached to one end of the handle and a wax applying swab 3 mounted on the head 2. The head 2 is pivotally connected to the handle at the end thereof, the end of the handle being provided with a sheet metal ferrule 4 fixed thereto and having laterally projecting flanges 5 which fit between upstanding flanges 6 fixed to the head 2 and pivotally connected with the flanges 6 by means of a transverse pin 7 extending through the flanges 5 and 6. The head 2 is preferably in the form of a sheet metal plate and flanges 6 may be struck up from the body of the plate, the flanges 6 preferably being positioned centrally of the plate. The axis of the pin 7 is preferably slightly to the rear of the transverse center line of the head 2 so that the forward edge of the head tilts downwardly as it is lifted from the floor.
The opposite side edges of the plate are rolled back to provide hollow beads 8 and the front and rear edges of the plate are rolled back to provide hollow stiffening heads 9. The heads 8, which form sockets to re ceive the ends of swab supporting bars 10, extend the full length 'of the side edges and the heads 9 terminate short of ends of the front and rear edges to accommodate the heads 8.
The swab 3 is preferably in the form of an endless loop of soft fabric such as knitted fabric and is secured upon the head 2 by means of front and rear supporting bars 10, which extend through the fabric loop and are detachably secured to the plate 2 at the front and rear sides thereof, the swab retaining bars 10 being formed of wire and of substantially U shape. The body portion of each of the bars which extends through the fabric loop is substantially straight and of a length greater than the width of the plate 2. At the ends of the straight portions thereof, the bars are bent to provide reversely curved portions 11 and end portions 12, which are inwardly offset with respect to the ends of the straight portion and extend at sub stantially right angles thereto. The end portions 12 of the bars 10 are adapted to be inserted in the open ends of the beads 3 at the opposite side edges of the plate 2 which form sockets for the ends of the bars and may be detached from the sockets by pulling the bar 10 outwardly. The bars 10 are preferably made ofspring metal and the ends 12 which fit in the sockets formed by the heads 8 are preferably bent outwardly so that they diverge at a small angle. In order to engage the ends 12 in the beads 8, the ends 12 must be sprung inwardly, the outward pressure of the ends 12 in the sockets formed by the beads due to the resiliency of the wire providing suflicient friction between the ends 12 and the walls of the sockets to hold the bars against accidental displacement.
To attach the swab to the head, one of the bars 10 is inserted through one end of the fabric loop and the ends 12 thereof are in serted in the open ends of sockets formed by the beads 8 at the front or rear of the plate 2. The second bar 10 is then inserted through the loop, the loop is drawn across the bottom of the plate 2 and the ends 12 of the second bar are inserted in the open ends of sockets formed by the heads 8 at the opposite side of the plate. The swab 10 is preferably of a width greater than the-width of the plate 2 so that opposite side edges of the swab overlie the curved portions 11 of the retaining bars and also project beyond the opposite side edges of the plate 8. The portions of the swab overlying the curved end portions of the retaining bars prevent lateral sliding of the fabric on the bars 10 and beneath the plate 2, so that when in use, the fabric is stretched not only between the front and rear sides of the plate, but also laterally so that it is held flat between the plate 2 and the floor. In applying wax to the floor, downward'pressure is exerted on the handle 1 while the swab 3 is being moved back and forth over the floor and this pressure ap plied centrally of the plate 2 maintains a head 2 when the swab 3 is removed.
substantially uniform pressure on the fabric in engagement with the floor.
lVhen it is desired to remove the swab 3 for cleaning or for replacement, it is only necessary to grasp one end of the swab and pull it outwardly from the edge of the plate a distance sufficient to detach the retaining bar 10. The opposite end of the swab can then be readily detached by pulling the other retaining bar out of engagement with its retaining sockets.
In applying the swab to the head, one of the retaining bars is inserted in the fabric loop and its ends 12 are sprung inwardly and forced into the open ends of the beads 8 at the front or rear of the plate 2. The second bar is then inserted through the loop and attached in a similar manner to the plate.
The swab 3 shown in Figs. 1 to 4 of the drawing is used for applying wax to the floor, but for rubbing the wax into the floor and imparting a high polish to the floor, the swab shown in Figs. 5 to 8 is used, the polishing swab being designed for attachment to ltjie ie polishing swab consists of a flat pad 13 of felt or similar material which is sewed to a cloth body 14 of larger size. The felt pad 13 is of rectangular shape and of a size to project slightly beyond the opposite side edges and the front and rear edges of the head 2 and the cloth body 14 is also of rectangular form and of a size to permit the edges thereof to be folded up over the top of the head 2 to secure the polishing swab in place. At each of the four corners thereof, the cloth body 14 has attached thereto string 14 which is knotted at each end as indicated at 15 and looped through the cloth at spaced points adjacent the corner thereof. Each of the strings 14 is of sufficient length to provide a free end for tying to the string attached to the adjacent corner, as shown in Fig. 7 of the drawing. By folding the cloth body 14 over the edges of the head and drawing the strings 14 together and tying them, the cloth body 14 may be securely held to the head 2 with the pad 13 lying flat against the bottom of the pressure applying head.
It would be apparent that the polisher of the implement of the present invention is very convenient and effective for use in waxing floors, that the means employed for detachably securing the wax applying and polishing swabs to the head makes it possible to very quickly and easily remove either swab and replace it with the other and that both swabs being formed wholly of fabric may be readily cleaned when desired. Furthermore, the swab carrying head is so mounted that pressure can be very effectively applied thereto through the handle.
What we claim is:
1. A polisher comprising a pressure applying head in the form of a substantially flat sheet metal plate having edge portions bent back over the body thereof to form hollow beads, a handle pivoted to said plate, wire bars extending along opposite side edges of said plate, said bars each having inwardly bent end portions detachably fitting in hollow beads of said plate, and a swab extending 1lgeneath the plate and secured to said cross ars.
