This invention relates to a mop which finds particular applicability in dusting and polishing floors and the like.
An object of the invention 1s to provide a mop of this kind wherein the-dustlng or polishing fabric or element may be very readily attached to, and detached from, the head of the mop, and wherein the dusting or polishing cloth protects the surface to be dusted or polished and the articles stand ng on the surface. In the present illu'stratwe disclosure, the polishing cloth, which, preferably, is formed of lambs wool, is adapted to overlap the edges of the head of the mop,
and the lambs wool is clamped in place on the head by means located within the compass of the head.
A further object of the invention is to provide a mop which is characterized by its extreme simplicity in construction, its economy in manufacture, and its durability in i use.
Other objects will be in part obvious and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the apphcation of which will be indicated in the appended claims.
In the accompanying drawings, wherein is illustrated one of the many embodiments which the present invention may take;
Figure 1 is a perspective View of the mop; Fig. 2 is a longitudinal sectional new therethrough, the dusting cloth or lambs wool being omitted; and
Fig. 3 is a transverse section taken substantially on line 83 of Fig. 1.
Referring to the'drawings in detail, the
numeral 10 designates a holder or head, preferably formed by stamping out a blank from sheet metal and then bending the blank to the shape illustrated. This head is gen-.
erally of rectangular shape and has, at each of its side or longitudinally extending edges, upstanding flanges or ribs 11 over which the marginal portions of the dusting and polishin fabric or material 12 are adapted to be f0 ded. This fabric or element 12 may be of any suitable material but, by preference,
it is a piece of lambs wool or sheeps skin as such material, when rubbed over a waxed surface, will give the desired polish thereto. At each end of the head isan upstandin ear 13 and these cars are suitably aperture to receive the ends of a rodv 14 which extends centrally and longitudinally of thehead from one to the other end thereof. The head is further provided with a air of spaced lugs 15 which are preferably ormed by making slits in the head and then bend mg the metal within the slits upwardly at right angles to the plane ofthe head. These lugs are adjacent to, and spaced an equal distance from, the center of the head and have two functions; one, to support and reinforce the central portion of the rod which passes through these lugs, and the second, to prevent movement of a hinge 16 longitudinally of the rod. In the present instance, this hinge is very simpl and economically formed of sheet metal by stamping out a blank of the desired configuration, and then bending u one end of the blank to form a knuckle 1 which is substantially continuous throughout its length and which, in length, corresponds to the distance between the lugs 15. The other end of the blank is rolled into a cylindrical socket 18, the axis of which is substantially at right angles to the axis of the knuckle 17. This socket is provided with a serrated screw thread19 with which cooperates a companion male thread on the lower end of a handle 20.
For the purpose of clamping the cloth or lambs wool on the head, there are provided a pair of jaw or gripping members, each of which has a gripping portion 23 and an arm 24 at each end pivoted on the rod 14. The gripping members are each preferably formed from sheet metal, the blanks or strips being bent to the shape illustrated. It will be noted that the gripping portions 23 extend longitudinall of the flanges 11 and are spaced latera ly within these flanges. The upper edge of each of the gripping portions has a laterally extending lip 25, and these lips serve to give a finish to the structure and also to provide a ledge by means of which the jaws may be raised when it is desired to remove or replace the cloth upon the head. The gripping members are urged into gripping position by suitable springs, each of which, in the present instance, takes the form of a central coil 26 encircling the rod 14, oppositely extending arms 27, and hooked ends 28 adapted to respectively hook overthe arms or end pieces 24: of the jaws. The gripping members, as stated, are pivoted for swinging movement on the rod 14, and are held against movement longitudinally of that rod by the ears 13.
From the fore oing description, taken in connection with t e accompanying drawings, it will be seen thata mop, constructed in accordance with the presentinvention, comprises a relatively few number of parts each of which is simple in construction, and the parts ma be readily assembled so that the mop can e produced at a relatlvely low cost. The lambs wool is held in lace upon the head in a very simple yet e ective manner by the gripping members, these members being made further effective by the upstanding flanges 11 over which the marginal edges of the lambs wool is bent or folded. The lambs wool may be very quickly and easily assembled on the head by merely swin ing the gripping members upwardly, fol ing the marginal edges of the lambs wool over the side edges of the head, and then releasing the gripping members, permitting the same, under the influence of the springs 26, to be moved into engagement with, and held tightly against, the lambs wool, The flanges 11 provide, at the forward and rear edges oi the head, relatively wide surfaces which are covered by ,the lambs wool so that the likeli-'- hood of in'ury to furniture or the like, in the event t at the mop strikes thereagainst, is avoided. a
I claim as my invention: 1. In a mop of the character described, a head with upwardly extending flanges along its side edges, a pair of clamping members pivoted to said head and having gripping portions extending longitudinally of, and spaced from, said flanges, each of said gripping portions also having at its upper edge a laterally extending lip, and springs urging said clamping members into clamping POSitiQIL' 2. In a mop of the character described, a
sheet metal head provided with a turned up ear at each end and a pair of upstanding lugs adjacent the central portion of the head and aligned with said ears, a rod extending through said lugs, gripping members ivot--,
ed on said rod, and. a handle formed 0 sheet metal and having a knuckle surrounding said rod between said lugs, said knuckle corresponding in length to the distance between said lugs whereby said lugs hold said knuckle against longitudinal movement on the rod.
