WING APPARATUS.

Application filed February 21, 1927. Serial No. 188,779.

My invention relates to a cleaning apparatus and important objects thereof are to rovide a device of the character described which will eatly facilitate the cleaning of ceilings, w ls and floors; which includes a readily removable and reversible cleaning element and a conveniently detachable holder for the latter; and which embodies novel resilient means for automatically adapting the cleaning element thereof to the surface of the work to be cleaned, and for imparting proper pressure to the cleaning element to effect the cleaning operation.

Further objects of the invention are to provide a device of the type stated which is simple in its construction and arrangement, strong, durable and eificient in its use, conveniently operable, ositive in its action, and comparatively inexpensive to manu facture.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within the scope of'what is claimed without departing from the spirit of the invention.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views Figure 1 is a rear side elevational view of a cleaning apparatus constructed in accordance with the invention;

Figure 2 is a side elevational view thereof.

Referring in detail to the drawing 1 denotes an integrally formed holder con structed from sheet metal and comprising a back wall 2 provided with a air of forwardly disposed side walls 3. T e marginal outer edges of the side walls 3 are bent inwardly toward each other and constitute se-- curing flanges 4 for detachably connecting the cleaning element 5 to the holder 1.

The cleaning element 5 preferably consists of an elongated piece of sponge rubber, which is normally substantially rectangular in transverse cross section. Each of the side walls of the cleaning element 5, is formed with an incision 6, which extends along the entire length and at the approximate center of the thickness of the cleaning element 5. In securing the cleaning element 5 to the holder 1 the securing flanges 4 extend into" respective incisions 6 and engage the rear portion 7 of the cleaning element 5 which is compressed and jammed into the holder 1 for securing the cleanin element to the latter as clearly shown in %igure 2. The projecting or cleaning portion 5' of the cleaning element 5 which is disposed forwardly of the holder 1 is utilized for cleaning purposes, and when worn from use, the cleaning ele-. ment 5 may conveniently be reversed in the holder 1 to provide a renewed cleaning portion. The projecting cleaning ortion 5 of the cleaning element 5 prefera 1y overlaps the side and end edges of the holder 1 to prevent potential injury to objects contacting with the apparatus during its use.

While the cleanin element 5, embodied in my invention is pre erably constructed from sponge rubber, it will be obvious that any other cleaning element applicable thereto may be em loyed without departing from the spirit 0 the invention. A pair of rearwardly disposed lugs, re-

spectively indicated at 8 and 9, are disposed adjacent to respective ends of the holder back wall 2. The lugs 8 and 9 are stamped directly from the latter and extend in opposite directions relatively to each other with the open sides thereof disposed toward respective ends of the holder 1.

A air of resilient supporting arms respectlvely indicated at 10 and 11, connect the holder 1 with the operating handle 12. The rearward ends of the arms 10 and 11 are preferably joined together and are permanently fixed in the forward ferruled end 13 of the handle 12.

The forward ends of the arms 10 and 11 are spread apart from each other and are suitabl formed as indicated at 14, to detachab y engage and overlap respective lugs 8 and 9 of the holder 1.

The rearward end portion of each of the arms 10 and 11 is coiled to provide a resilient spring 15. The latter provide a resilient action for maintaining the securing engagement of the arms 10 and 11 with respective ugs 8 and 9,until manually detached thererom.

Normally the arms 10 and 11 extend forwardly with a lateral spread, from the handle 12, but the action of the springs 15 will permit of the arms 10 and 11, together with the holder 1 and cleaning element 5 carried thereby to be forced to extend rearwardly at right angles relatively to the handle 12, as shown in dash lines in Figure 2, or to assume any an lar disposition between such right 811F521 disposition and their normal forward y This construction of arms 10 and 11 will provided for the auomatic adjustment of the cleaning element 5 to flatly engage the surface to be cleaned while exerting a resilient pressure to the cleaning element 5 that will greatly facilitate and expedite the cleaning operation.

What I claim is:

In combination a cleaning apparatus of the character described comprising a recelement removder, said holder sheet metal holder includ meme? 1 provided with'a thereof and disposed adjacent to respective ends of said holder, an 20 tspread alignment. operating handle, a pair of supporting arms having their rearward. ends rmanently fixed in the forward endof saifiandle, the fgrlward ends pf said pair of arms detacha y respective y engagin said air of In the rearward end portion 5f each of said p i i of arms being formed to provide a spring for maintaining said pair of arms in engage- 2111161113 with said lugs said spiral springs furer of said carrier relatively to said operating handle.

In testimony whereof I permitting varied tensional adjustment :0
