SPONGE MOP WITH ADJUSTABLE HANDLE AND SQUEEZER MEANS Filed June 9, 1955 3 Sheets-Sheet 5 Fl G. 8.

INVENTOR 5mm-.Y P VAUGHN www ATTORNEY United States Patent =`SPONGE MOP 'WITH ADJUSTABLE I'ANDLE AND SQUEEZER PVEA S Sidney P. Vaughn, San Diego, Calif. ApplicationJune 9,11953,SerialfNo. 360,550 Y8 Claims (C115- 119) .My invention relates to cleaning devices commonly known vas wetmops, and moreparticularly to thattype of wet mop in Vwhich a block of compressible andabsorbent vsponge material is usedas the cleaning or scrubbing element,;combined with mechanical means for squeezingthe .water out of the cleaning element.

In certain sponge mops, one of the means for squeezing Water .out of the sponge cleaning element is a presser plate, generally hinged either to the front or tothe back of the mop head, and adapted to swing intosqueezing contact lwith the sponge cleaning element. Another means commonly provided causes the sponge cleaning element to fold upon itselfto squeeze out thewater. The principalfault with either of vthe above methods is the trapping ofdirt in the sponge element,and the length ,of time required to clean the sponge by themechanical means used. Anotherfaultis that the sides of the mopis'limited to. the size of theusualhousehold pail.

Another method employed to squeeze water out of the spongeis to provide opposed rollers, paralleltwith'thefxed mop head, at right angles to the mophandle. vIn such mops, the general practice is to squeeze aboutone third of the sponge cleaning element into a narrowchannelfshaped mop head. For absorption purposes, about onethird of the sponge is wasted, and the size of the mop is limitedto the sizeof the average household pail.

It generally takes from two to four pounds pressure per square inch to squeeze sponge fairly dry, depending ,upon the kind of sponge used. Hence, the greaterjthe number of squareinchesemployed inthe scrubbing surface of the ,sponge mop, the greater will be the force .required to squeeze outthe ywater by any of the foregoing means.

The primaryobject ofthe inventionis to provide a mop in whichthe size of the mop head is not limited by thesize of the ordinary household pail, and one that will,readily squeeze the water out of the sponge cleaning element and clean the sponge with a minimumamountof eiort.

A further -objectof the invention is to provide :a-scrubbing mop having novel and simplified means for squeezing the water from the sponge element of the mop.

A further object is to provide in a Vmop ofthe abovevmentioned character a simplified and durable adjustable handle connection, which permits the mop to be used while the mop handle is in various angularly adjusted .positions relative to the mop head.

A further object is to provide an adjustable squeezing unit, bodily mounted upon the mop handle, and arranged not to interfere with normal usage of the mop.

A further object is to provide a movable squeezingdevice which makes use of the mop head plate as aguide or track during thesqueezing operation.

Another object is to provide means on the mop handle for holding or stowing the movable squeezing device, so that the mop may be used in the normal manner without displacing or moving the squeezing device.

Another'object is to provide a swivel -joint'for the Amop handle which releasably `holds the `same in 'upright-"and lowered positions.

plate of substantially stiifsheet metal, or thelike. headplate 20 ,is{at, as shown, and provided at its longiltudinaledgeswith shortdepending anges 21, preferably integral therewith, and extending throughout the entire length o'f the" head plate.

duringit-s use.

A; pair of upwardly directed screws 25 engages vthrough 'registering -`openings 1in the head and'backingjplates 20 -and 23, -inwardly"off'their/ends,lFigure '2, and-wingnutsI 26 are fapplied 'tofthescrews l25, and engage :the -top ofthe 'bracket 27 comprises a flat head plate 20, for releasably securing the sponge refill assembly to the head plate.

A handle mounting bracket or adapter 27 is provided, and is preferably formed of sheet metal, or the like. This elongated rectangular bottorn 28, and spaced opposed upstanding sides 29, rigidly secured to the bottom 28 and preferably integral therewith. The sides 29 are parallel, and extend longitudinally of the head plate 20, and the bracket 27 is substantially narrower than the head plate, as shown. The bracket 27 is applied centrally to the head plate 20, and rigidly secured thereto in any suitable manner, such as by spot weld ing the bottom 28 to the head plate 20. The bracket 27 further comprises low upstanding ends 3l) and 31, rigidly secured to the bottom 28 and sides 29. The bracket 27 is arranged midway between the screws 25, and extends longitudinally over a considerable length of the head plate 20.

A mop handle 33 of vided, and an attaching in the lower end of the handle 33 by a transverse pin 35, or the like. The attaching head 34 projects forwardly of the adjacent end of the handle, and is bifurcated to form a pair of opposed extensions 36, engaging between the upstanding sides 29, and preferably slidably engaging the same. The head 34 is pivotally secured to the sides 29 by a transverse pin 37, engaging through aligned openings in the extensions 36 and sides 29.

A pair of friction rollers 38 extends transversely between the extensions 36, near and freely journaled upon transverse pins 39, rigidly se cured to the extensions 36. A leaf spring 40 is arranged upon the bottom 28 of the bracket 27, below the head 34, Figure 2, and this leaf spring is held against transverse and longitudinal movement by the sides 29 and ends 30 and 31. lThe spring 4t! is arched upwardly, and has a substantially tlat central portion 41 for engagement with the friction rollers 38, whose peripheries project slightly beyond the sides and ends of the extensions 36. The ar rangement is such, that the leaf spring 40 coacts with the rollers 33 to releasably hold the mop handle 33 in the lowered horizontal position of Figure 2, or in the upright position of Figure 4. The handle 33 is swingable counterclockwise in Figure 2, for a full 180 degrees, so that the handle may extend horizontally beyond the other end of the mop head plate 20. The handle 33 may of course be held in any desired intermediate position between the horizontal and vertical, during the use of the mop, and the spring 40, and associated elements, merely metal tubing, or the like, is proserve to releasably hold the handle in three major adjnsted positions, 90 degrees apart. The handle 33 may, of course, be any desired length.

I provide squeezing means for the compressible sponge block 22, comprising a stationary holding device or member 42. The member 42 has an upper portion 43, sub- Y stantially U-shaped in cross section, Figure 8, and engaging about the upper side of the handle 33 snugly, as shown. The U-shaped portion 43 is rigidly secured to the handle 33 by rivets 44', or the like. The sides of the U-shaped portion 43 terminate somewhat below the handie 33, Figure 2, and are bent laterally outwardly, at right angles to the sides for forming relatively narrow at shoulders 44. The shoulders 44 are at the elevation of the head plate 2t), and in alignment therewith, when the mop handle 33 is horizontally disposed, as shown in Figure 2. The member 42 further comprises spaced opposed parallel side extensions 4S, secured to the outer ends of the shoulders 44, and arranged at right angles thereto. The side extensions 45 project below the shoulders 44 for substantial distances, and have their lower ends terminating near and above the lower face of the sponge block 22, Figure 2.

The side extensions 45 have relatively narrow flanges 46 rigidly secured to their inner faces, in opposed relation, and these flanges include upwardly arched cirhead 34 is rigidly secured withtheir forward extremities,

cularly curved portions 47, and inclined cam portions or shoulders 48, integral therewith. Forward vertical portions 49 of the anges 46 extend above the inclined portions 48, and have their tops terminating at the lateral shoulders 44, Figure 2. The tops of the curved portions 46 are spaced above the lower ends of the inclined cam portions 48, as shown. The forward vertical end of the stationary member 42, adjacent to the ange portions 49 is in substantial alignment with the adjacent end of the sponge block 22, when the handle 33 isin the fully lowered position of Figure 2. Except for the narrow anges 46, the member 42 is open between the side extensions 45, and the sides of the U-shaped portion 43.

The squeezing means further comprises a movable carriage 50, adapted to travel longitudinally of the handle 33 and head plate 20, when the mop handle is in the lowered position of Figure 2. The carriage 50 comprises an upper generally U-shaped portion 51, larger than the U-shaped portion 43, and adapted to pass over the portion 43 telescopically, as shown. The sides 50' of the U-shaped portion 51 terminate just above the shoulders 44, Figure 8, and are bent laterally outwardly at right angles, to form companion lateral shoulders 52, integral therewith and slidably contacting the tops of the shoulders 44. r[he carriage 50 further comprises spaced opposed parallel side extensions 53, integral with the shoulders 52, and arranged at right angles thereto. The side extensions 53 engage outwardly of the side extensions 45 of the relatively stationary member 42, Figures 2 and 8. The lower ends of the side extensions 53 terminate slightly below the lower face of the sponge block 22, Figure 2. The forward edges 54 of the side extensions 53 terminate adjacent to the end of the sponge block 22, Figure 2. The carriage 50, which is generally U-shaped, is open between its sides, and adapted to move telescopically over the member 42, as stated, with the shoulders 52 slidably contacting the companion shoulders 44 of the member 42.

' The sides 50 and the shoulders S2 extend forwardly of the forward edges 54, Figure 2, so that the shoulders 52 are simultaneously in engagement with the shoulders 44 and the top of the head plate 20, Figure 2, when the carriage 50 is in the retracted position shown in Figure 2. The arrangement is such that the forward portions of the shoulders 52 form positive stops against the head plate 2t), to limit the downward swinging movement of the mop handle 33, when the same is lowered.

A cylindrical squeeze roller 55 is freely journaled upon a transverse axle or pin 56, engaging slidably in slots 57, formed within the side extensions 53, and opening through the bottoms of the side extensions. The squeeze roller 55 extends for the full distance between the side extensions 54. The length of the roller 55 is at least equal to the width of the sponge block 22, so that the squeeze roller can effectively squeeze the sponge block over its entire area. The squeeze roller S5 and its axle 56 are shiftable longitudinally within the slots 57, toward and from the handle 33.

The ends of the axle 56 project somewhat outwardly of the side extensions 53, for engagement with wire loops or clips 58 secured to the opposite ends of a heavy elastic band 59, of rubber or the like. The elastic band 59 engages over the sides and top of the carriage 50, as shown, and is tensioned to exert a considerable pull upon the axle S6, such as a ten pound pull, or the like. The elastic band 59 constantly urges the squeeze roller 55 toward the mop handle 33 and the slots 57 which are at right angles to the mop handle, guide the squeeze roller in its movement toward and from the mop handle 33. The squeeze roller 55 is bodily movable with the carriage 50, longitudinally of the handle 33 and head plate 20.

Means are provided to shift the carriage 50 longitudinally of the handle 33 and head plate 20. Such means comprises a sleeve 60 or slide handle, slidably mounted upon the handle 33, a substantial distance above the carriage 50. 'f he slide handle 66 is provided at its forward end with a pair of apertured ears -push rods 63 extend substantially `movement of the carriage handle.

"The side extensions 53 of the carriage ylateral movement of the same, during its \in the retracted 61, rigidly -secured1by rivets 62 to the rear ends of a pair of push-rods 63. These longitudinally of the handle 33, on opposite sides thereof, Figure 5, and have their forward portions rigidly secured by rivets 64 to the sides 50' of the generally U'shaped portion 51, just above the shoulders 52, Figure 1. As best shown in Figure 5,

`the push rods 63 diverge somewhat toward their forward ends, since the distance between the sides' 50 is somewhat greater than the distance between the ears 61. The push rods 63 are preferably substantially rigid.

In operation, the carriage 50 is retracted by means of the slide handle 6?, until the squeeze roller 55 snaps under the curved portions 47 of the flanges 46,v by rolling over the inclined cam portions 48. The elastic band 59 stretches to permit this action of the squeeze roller. The shoulders 52 are now in engagement with thefshoulders Y44, which-serve as tracks for the carriage 50-in the retracted position, and also in engagement with the top of the head plate 20, Figure 2. With this arrangement, as previously stated, the shoulders 52 form positive stops tolimit the downward swing of the mop handle'33 in Figure 2, and assure proper alignment of the carriage 50 with the head plate and the stationary member 42.

The mop handle 33 may be readily adjusted by swinging the same about its pivot 37, to any intermediateposition, or to the upright position of Figure 4; and the-leaf spring coacts with the rollers 38 to releasably hold the handle 33 in the three major adjusted positions, 90 degrees apart. During angular adjustment of the mop handle, the member 42 and carriage 50 swing as a unit with the mop handle, and the engagement of the squeeze roller within the curved anged portionsv 47 prevents longitudinally of the mop When it is desired to squeeze water out ofthe sponge block 22, the mo-p handle is swung to the position shown in Figure 2, wherein the shoulders 52 engage the `top of the head plate 20. The slide handle is grasped for shifting the carriage Sil forwardly, longitudinally of the 4-mop handle 33 and head plate 20. The shoulders'52 -slide from the shoulders 44, and slidably engage theside marginal portions of the head plate 20,which serves `as a guide or track for the carriage 50, during the squeezing operation. of the head plate 20, so that the above described movement of the carriage 50 along the head plate 20 is possible. are 'disposed just outwardly of the anges 21 of the head plate, and coact with these anges to guide the carriage movement longiplate. When the carriage50 -is position, Figures l and 2,the side'portions 54) remain in overlapping engagement with the tudinally of the head lianges 21, to assure proper alignment of -the carriage with the head plate 20, during the squeezing operation.

`When the carriage 50 is shifted forwardly'along'the head plate 2t), the squeeze roller 55 moves out ofl engagement with the anges 46, and rolls along the entire length of the sponge block 22, to squeeze or compress 'the same tightly against the backing plate 23. This action expels the water from the sponge block, and the carriage'50 and squeeze roller are shown in their forwardmost positions in Figure l0. Forward movement of the carriage 50 1s limited by engagement of the forward 4end ofslide `a second thorough squeezing by the squeezeroller. YThe The shoulders 52 are aligned with the top.v

stantly engages the ball detent and holds the same within the bore 74. The ball detent 84 cooperates with the notches 80, to releasably hold the mop handle in either the upright position of Figure ll, or the lowered horizontal position, not shown, wherein the shoulders 52 engage upon the head plate 65. The mop handle 33 is of course shiftable to any intermediate angular position between tlie notches 80, and in fact, the mop handle is swingable through a full 180 degrees, like the rnop handle 33 in the first form of the invention. The spring 82 yields to permit disengagement of the ball detent 84 from the notches 80, when suicient force is applied to the mop handle for pivoting the same about the pin 81.

In Figures ll to 14 inclusive, the identical means 'for squeezing the sponge element 22 is provided, as previously shown and described in connection with the first form of the invention, and this means includes the carriage 50, and associated elements, as well as the member or holder 42, and associated elements. These parts function for squeezing the sponge block 22, in the identical manner, shown and described in connection with the first form of the invention, and no further description of their construction and mode of operation is necessary here. All other parts of the mop in Figures ll to 14 inclusive are identical with those shown and described in connection with the first form of the invention.

While I have shown and described the sponge block 22 as rectangular in transverse cross section, and the squeeze roller 55 as cylindrical, it should be understood that the sponge block may be formed trapezoidal in cross section, if preferred, in which case, the squeeze roller may be formed conically tapered, for proper engagement with the inclined working surface of the sponge block.

It is to be understood that the forms of the invention,

herewith shown and described are to be taken as prev ferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope ot the subjoined claims. v

Having thus described my invention, I claim:

l. A mop device comprising a head plate, a compressible scrubbing element arranged upon one face of the head plate and secured to the head plate, a handle arranged upon the opposite face of the head plate and pivotally mounted upon the head plate and swingable to a posi- ,i
