PATENT oFFicE MOP Warren G. Bailey, Evanston, Ill., assigner, by mesne assignments, to Reconstruction Finance Corporation, Chicago, Ill., a corporation Application October 9, 1937, Serial No. 168,285
This invention relatesto a mop and more particularly to a mop in which the mop head is readily withdrawable from the mop body, the mop being useful for dusting and other purposes.
An object of the invention is to provide a mop of extremely simple construction which is readily flexible in practically all directions and in which the mop head can be compressed laterally to per- .mit its insertion within or removal from the l0 mop body. A further object is to provide a mop head which can be readily manipulated vby a novice and which can be assembled or disassembled without changing the shape of -the spring loop carried by the head. A further object is to provide a mop head equipped with a spring loop portion which is maintained in a desired elongated shape and which can be operated in loosely held as well as tightly held position Within the clamp of the head. Other specific objects and advantages will appear as the specification proceeds.
The invention is illustrated in a preferred embodiment, by the accompanying drawings in.
which- Figure 1 is a plan View of a mop embodying my invention, the yarn of the mop body being omitted; Fig. 2, a broken plan view of a mop similar to that shown in Fig. 1, the tie strings being loosened; Fig. 3, a plan view of the clamping member shown in flat position just before being bent to engage the spring loop; Fig. 4, a detail sectional view, the section being taken as indicted at line 4 of Fig. l; Fig'. `5 a plan view of the mop provided with the usual yarn or thread; and Fig. 6, a transverse sectional view, the section being taken as indicated at line 6 of Fig. 5.
In the illustration given, A designates a handle provided with a metal threaded ferrule A'; B,
- a wire coil serving as a union; C, the mop head;
and D, the mop body.
The handle A may be of any suitable type or construction. Ity is equipped, as shown, with the usual metal ferrule Ay which is threaded to receive the coil union B. The coil union B is of well known construction and need not be described in detail.
'I'he mop head C may be of any suitable construction. In the form illustrated, I provide a metal clamp Ill which is formed, as illustrated more clearly in Figs. 2 and 3, from a single piece, bent upon itself at II. The clamp is provided with aligned holes I2 'through which extends a 55 bolt I3 engaged by a nut I4. The outer aligned ends of the clamp I0 provide a curved passage I5 adapted to receive a spring coil I6.
The spring coil I6 is preferably formed asillustrated more clearly'in Figs. l and 2. TheA coil is provided on one side with a reduced portion I1 which enters and locks with the adjacent larger end of the spring. It is found that this connection provides a secure and permanent union of the two ends so that there is no tendency for them to separate u nder stress or exure. At the 10 same time I find that the reduced portion I1 because of its resistance to bending helps in maintaining the spring in the elongated shape shown in Fig. 2. This construction also facilitates the lateral bending of the entire spring when the 15 same is to be inserted within the pocket of the mop body D.
I prefer to locate the portion I1 along one side of the spring loop, as illustrated in Fig. 2, while at the same time bringing an integral and 20 uniform portion of the spring within the clamping chamber I5 of clamp I0; I have found that when a continuous portion of the spring is clamped within the member I0 that more even and uniform flexing of the entire spring results. 25 Also, should the clamp work loose, the nut I4 being worked to someextent 01T of the bolt I3,
there is no tendency for the spring to slip out of the clamp, as there would be if free ends of the spring were enclosed within the clamp. When 30 the clamp becomes quite loose, it is only necessary for the operator to tighten the nut and the spring is again securely held in position.
The mop body D may be of any suitable con. struction. In'the illustration given, I have pro- 35 vided a fabric pocket formed by sewing two overlapping pieces of fabric together, the pieces being stitched together as indicated by the dotted line I8. 'Ihe yarn strings or threads I9 are stitched to the fabric body along its edges and other 40 suitable points so as to provide a substantially continuous covering of yarn. It will be understood, however, that the forming of the yarn body may be varied considerably to adapt the mop to any particular desireduse.
It will be observed that the stitch as illustrated provides a substantially fan-shaped pocket 20, the pocket being of constricted cross-section at its lower end. The fabric is perforated near its lower end at 2l to permit a tie member 22 to be 50 drawn therethrough.
In assembling the mop, the tie member is allowed tofremain loose and thespring I6 of the head is compressed laterally so as to narrow its dimensions suiiiciently to permit it to enter the then fed forward, the succeeding portions of the spring I6 being successively compressed so' as to permit it to pass into' the pocket. Once within the pocket, the spring I 6 expands to ll the pocket as illustrated more clearly in Figs. 1 and 2. The threaded end of the clamping member I is screwed Within the coil union B, and the coilsv union B'ls threaded upon the ferrule A' of handle A. After the mop head has been placed in position, the tie member 22 is drawn tightly around the coil union B and tied as illustrated in Fig. l. Y
In disassembling, it is merely sufficient to untie the member 22 and then draw 4the head rear,
-wardly, the pressure exerted by the sides of the fabric pockets being suicient to laterally compress the spring I6 and to permit it t slide out of the constricted opening of the pocket.
The operation of insertion and removal of the head is extremely simple, requiring no removal or release of the spring member I6. Should the spring become loose at any time, there is no tendency for it to fly apart; it remains in the clamp I0 until the operator can tighten the nut. The spring head is extremely iiexible, bending uniformly under strain.
While in the foregoing description, I have set forth a speciiic form of the device as illustrative,
it will be understood that there may be many changes in the details of construction Without constricted portion of the pocket; The spring is departing from the spirit of my invention. The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom,- but the appended claims should be construed as broadly as permissible, in view of the prior art. l i.
