Patented Dec. 15, 1942 UNITED STATES PATENT OFFICE CLEANING DEVICE Solomon Schulman, New York, N. Y. Application December 31, 1938, Serial No. 248,852-

1 Claim.

This invention relates to surface cleaning devices, such as mops, brushes, squeegees and the like.

One of the main objects of this invention is to provide a cleaning device, of which a cleaning unit is adapted to slide on and off the head or body portion attached to a handle.

Another object is to make use of the handle for preventing the cleaning unit from sliding off the attached body portion.

A further object is to provide a novel holder for applying the cleaning unit and which is adapted to slidably connect with the body portion.

Another object is to provide novel means of securing the holder members of the cleaning unit to each other, whereby to maintain the cleaning means on these members in a permanently locked condition.

A further object is to provide on the head i or body portion of said cleaning device a suitable brush adapted for applying it in conjunction with the cleaning means on the attachable unit.

These and other objects of the invention will be pointed out and described hereafter.

In the accompanying drawing which illustrates the invention:

Fig. 1 is a side view of shown partly in section.

Fig. 2 is a perspective view of a body unit.

Fig. 3 is a perspective view of a holder-slide.

Fig. 4 is a perspective view of a squeegee.

Fig. 5 is a perspective view of a holder-bar.

The novel cleaning device shown in Fig. 1 comprises in the main a body unit 5, having a handle 2, and a cleaning unit 3, adapted to slide into and out of the lower surface part of the body unit.

This body unit I comprises a head or body my cleaning device portion 4, preferably made of wood or similar material. It is of substantially rectangular formation and has in its middle portion a coarsely threaded hole 5 adapted to receive the threaded end of handle 2. The head 4 is provided on one of its long sides with slanted surfaces, of which the lower surface 6 thereof is provided with tufts of bristles l forming a brush 8.

The cleaning unit 3 comprises a holder i5, consisting of a holder-slide l6 and a holder-bar I1, which are adapted to maintain between them the cleaning means in the form of a mop l 8 and a squeegee IS. The latter is made of soft rubber having a thin intermediate portion 20 and heavy side portions 2|, 22.

When assembling the cleaning unit 3, the middle portion of the mop I8 is first placed between the two upright prongs 23 of the holder-bar H. The rubber plate 69 is then placed on top of the mop with its flat surface down. Thereafter the lower surface of the holder-slide iii is forced against the assembled parts, spreading and pressing the rubber plate outwardly and against the mop, as shown in Fig. l. The prongs 23 of the sheet metal holder-bar will then be bent over in the direction shown in dotted lines in Fig. 5, whereby they will be forced to enter a wide, longitudinal arranged groove 24 in the middle of the holder-slides support plate 25.

After the prongs 23 have thus been bent over and forced to rest flat in the groove 2:4, tne mop and the squeegee will form a complete, self-contained unit with the holder l5.

In order to readily and quickly attach this unit to the lower surface of the body portion 4, the holder-slide Hi is provided with two side flanges 2B, which are inclined toward each other.

These side flanges are adapted to slide into inclined slots 21 which pass through the entire length of the lower part of body portion d. The lower surface 28 locatedbetween both the inclined slots, is curved or hollowed, to permit the grooved support plate 25 with the bent over prongs 23 to pass underneath said lower surface.

When entering and sliding the inclined side flanges in the slots 21, it is essential to have the shoulder 29 of handle 2 partly raised above its contact surface on the body portion, to permit the side flanges and therefore the entire cleaning unit to enter full length into the body portion. Thereafter the handle may again be screwed home, which will then enter the lower end portion of the handles thread into two circular shaped notches 30, which are provided in the middle of the flanges of holder-slide iii.

The cleaning unit is thus kept locked in the body portion, in that the notches Bil. touching the circumference of the screw thread, will prevent a sliding motion in either direction.

It is evident that the novel feature shown and described requires very little effort to attach or detach the cleaning unit. A twist of the handle and a simple sliding motion for the cleaning unit is all that is required for either taking off or replacing this unit.

A brush 8, a rubber l9 and a mop it are thus combined in one cleaning device adapted to provide thorough and complete cleaning operations by the user.

Having described my invention, it is understood that various modifications may be made Without departing from the spirit and scope of my invention.

What I claim is:

In a device of the character described a wooden block constituting a body portion, a handle screw-threaded into said body portion, said body having a plurality of separate obliquely arranged longitudinal slots opening into thebottom face of said body which is opposite said handle, and said slots approaching each other within said body, a cleaning unitcomprising a holder slide, a holder bar and cleaning means between said slide and said bar, the end portions of said holder bar being bent over and about the face of said holder slide for permanently maintaining said cleaning means in locked condition, said holder slide having an intermediate portion with separate flanges extending obliquely upwardly and inwardly toward each other from its edges, said flanges being inserted within said slots and the free edges thereof being separated from each other by a portion of said wooden block, said free edges having recesses and said handle extending within said block, between said free edges and into said recesses.
