(01. 15-231) My invention relates to improvements in dust of the part I cause the edges I of the flexible cloth holders, and it consists of the combinations, member B to extend downwardly at an angle constructions and arrangements hereinafter deand to space the part 4 above the floor 8, see scribed and claimed. Figure 3. The handle is composed of a wooden An object of my invention is to provide a dust portion 9 that is received in a ferrule III. Fig- 5 cloth holder which makes use of a frame for a ure 2 shows how the ferrule has a pivotal conresilient member, the resilient member projecting nection at II with a clip I2. The clip in turn beyond all of the marginal sides of the frame. has a pivotal connection at I3 with a bracket I4, The device further makes use of a dusting cloth the bracket being secured to the top piece I. The

The rod and cloth in this 55 instance will act as a stop and prevent the dirt from passing over the top of the frame A, while the device is being moved forwardly on the floor. It should be noted that inclining of the sides results in a better sweeping action and further results in spacing of the part 4 above the floor so that the metal part cannot engage with the floor to mar it. The dust cloth E will also collect and hold more material and the sweeper can adjust itself to unevenness in the floor.
When using the dusting cloth E the cloth is preferably dampened and the ends are wrapped around the rods l5 and It so that the unused portions of the cloth will be wrapped adjacent to the rods. In this way the unused portions of the cloth are prevented from drying out too rapidly. The cloth when secured to the frame will take the positions shown in Figures 3 and 4. The portion of the cloth disposed beneath the frame will act as a dust collector while the advance rod I6 will act as a stop and prevent the larger pieces of dirt from passing over the top of the frame.
When the operator wishes to provide the undersurface of the frame with a new portion of cloth, 1
he merely lifts the knob 26 and this frees the rollers l5 and i6 and permits them to roll off from the frame A by gravity. The frame can now be entirely removed from the cloth, and rollers, by merely lifting the handle 9 and it is not necessary for theoperator to stoop down when freeing the-frame from the rollers and cloth. The operator can now with his foot roll the roller IS on the floor to wrap up the soiled portion of cloth. This movement will cause the other roller to revolve and to provide a cleaned and dampened portion of cloth between the rollers. The frame A can now be lifted and placed over the cleaned portion of the cloth. The operator now moves the knob 26 upwardly, and with his feet can roll the rods or rollers I6 and I5 upwardly on the inclined portions of the frame, and when the rods are disposed adjacent to the leaf spring IS the knob 26 can be freed, and this will cause the clamps I I and I8 to again engage with the rollers. It will be seen that the entire operation of bringing a clean portion of cloth into a position underlying the frame can be accomplished without the necessity of the operator kneeling down or stooping over for any part of the operation. The cloth is preferably made of said frame, and a U shaped cloth clamping member secured at each end of said spring, said U shaped members extending transversely across and having their legs' extending down along the sides of said frame.

In a dust cloth holder, a flat, elongated rectangular frame, a dust cloth passing underneath the frame, two rollers having opposite ends of the dust cloth wound thereon and means for releasably mounting the two rollers upon the top of the frame adjacent and substantially parallel to each of the longer sides, the longer sides of the frame being inclined outwardly and downwardly substantially from the top to the bottom of the frame for permitting the rollers to be rolled up on top of the frame from a position on the floor, or vice versa.

In a dust cloth holder, a flat, elongated rectangular frame, a dust cloth passing underneath the frame, two rollers having opposite ends of the dust cloth woundthereon, means for releasably mounting the two rollers upon the top of the frame adjacent and substantially parallel to each of the longer sides, and a common operating means for releasing the two rollers, the longer sides of the frame being inclined outwardly and downwardly substantially from the top to the bottom of the frame for permitting the rollers to be rolled up on top of the frame from a position on the floor, or vice versa.
