May 14, 1940. T. A. PURVIS MOP Filed Sept. 6, 1938 INVENTOR,

ATTORNEYS.

Patented May 14, 1940 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to mops and particularly such a device as is usable in connection with cleaning or household work and the primary object of the invention is to provide: a mop struc- .1 ture wherein is incorporated the conventional type handle and a unique and specially constructed head that is mountedupon the handle and carried in such fashion as to have the rubbing surface thereof positioned in any one of a large number of planes angled with respect to the longitudinal plane of the handle so that various positions may be assumed by the headof the mop during its use.

One of the important aims of the invention is to provide a cleaning mop of the aforementioned character which has a head adapted for yieldable movement to and from a plane common to the axis of the mop handle, said movement being affected and insured through the employment of novel parts including structure which will hereinafter he set down and which constitutes some of the aims of the present invention.

In the drawing,

Figure 1 is a perspective view of a mop made to embody the present invention.

Fig. 2 is a top plan view of the head and a portion of the handle thereof with part of the cover removed to reveal the parts constituting the mop head. 1

Fig. 3 is a fragmentary side elevation of the mop with the cover entirely removed.

Fig. 4 is a fragmentary, detailed, sectional view through the portion of the mop head and handle which form the connections therebetween,

and

Fig. 5 is an edge view of the frame constituting the mop head.

The mop which is constructed to embody this invention should comprise a handle 8, having a fixture l0 secured to one end thereof through the medium of a screw or similar element l2, which fixture carries a longitudinally extending pintle 14 that is screw-threaded as illustrated in Figs. 2 and 4 to engage an internally threaded.

opening 15 formed through cross-bar It. This cross-bar I6 is thereby rigidly secured to handle 8 and if a shorter handle is desired, the longer one illustrated, may be conveniently removed and another type moved to position. This removable feature as between handle and cross-bar 8 and 16 respectively, also allows changing of the cover l8 which forms a part of themop head.

Cover I8 is of fabric and may be provided with conventional type yarn or similar structure as illustrated. This case I8 is provided with openings 20 through which may pass the pintle l4 when securing the case in place. Two'or more of these openings may be provided so that the case may have different portions of its surface presented to the work. Vfhen the case is posi- 5 tioned, pintle I4 passes through openings 20 and thence into opening l5 of member l6 so that the case it! is clamped between the end of fixture l0 and one side of cross-bar l6. H

The mop head itself is uniquely formed and 10 includes as a part thereof, the case and cross-bar just described. Case It should be tubular so that it may be slid over the parts of the head and to fulfill the principal object of the invention, a substantially U-shaped yoke 22 is provided which 15 has legs 24 and a base 20. The ends of said legs 24 are formed to present eyes 28 which circumscribe a reduced portion 30 of bar I6. This reduced portion is formed by notching the bar inwardly from each longitudinal edge thereof and 20 when eyes 28 circumscribe this reduced portion, an effective hinge is provided which allows yoke 22 to swing about the hinge connection but precludes lateral displacement of legs 24. The base 26 of this yoke 22 is provided with kinks 32, one 25 of which is disposed on each side of the center of base 26. These kinks are engaged by the ends of spring 34 and preclude the movement of these spring ends along base 26. The other ends of spring 34 are brought together and connected 30 to a bracket 36 that is carried by bar l6 adjacent the longitudinal center thereof, thus a substantially continuous V-shaped spring structure is provided which joins base 26 and bracket 36. The point of connection between the ends 35 of springs 34 and bracket 36 is to one side of the axis of the hinges which are formed by the joint between yoke 22 and bar I6. This eccentric relation between the point of connection between the ends of springs 34 and yoke 36 and 40 hinges formedby eyes 28 of yoke 22, insures that the parts of the mop head will be yieldably disposed in a common plane. Whenever the mop is used and the case and yoke are moved out of said plane as illustrated in Fig. 1, the springs 5 34 will serve to return the parts of the mop head to the original plane as soon as pressure is released.

The form of this mop head is unique in that it is unobstructed throughout its entire working 50 face with the exception of that small area taken up by the connection at the end of handle 8. g

It is obvious that when the parts of the mop head are moved to and from. the normal plane, there is no bending of the yoke nor any other 55 part of the mechanism and, therefore, no wearing or crystallization of spring members or the like is attached to said cross-bar; a bracket extending laterally from the cross-bar between the legs of; said yoke; a spring extending from the base of said yoke to the said bracket; and a cover en-' casing said yoke. v

2. A mop of the character described comprising, in combination, a handle; a cross-bar'secured to said handle; a substantially U -shaped yoke having the ends of the legs thereof hingedly attached to said cross-bar; a bracket extending laterally from the cross-bar between the legs of said yoke; a spring extending from the base of said yoke to the said bracket; and a cover encasing said yoke, the said'spring and bracket being pivotally connected on an axis eccentric to the axis'of the connection between said yoke and cross-bar.

3. A mop of the character described comprising, in combination, a handle; a cross-bar secured to said handle; a substantially U-shaped yoke having the ends of the legs thereof hingedly attached to said cross-bar; a bracket extending I laterally from the cross-bar between the legs of said yoke; a spring extending from the base of said yoke to the said bracket; and a cover encasing said yoke, the said spring and bracket being pivotally connected on an axis eccentric 10 to the axis of the connection between said yoke and cross-bar; said cross-bar, yoke, spring and bracket being normally in a common plane.

4. A mop of the character described comprising, in combination, a handle; a cross-bar se- 15 cured to said handle; a substantially U-shaped yoke having the ends of the legs thereof hingedly attached to said cross-bar; a bracket extending laterally from the cross-bar between the legs of said yoke; a spring extending from the base of I) said yoke t0 the said bracket; and a cover encasing said yoke; said spring being V-shaped with the b ight thereof in'connection withsaid bracket and the ends thereof in connection with the base of said yoke, said spring, yoke and cross- '5 bar beingnormally in the same plane.
