Application March 29, 1955, Serial No. 497,529

8 Claims. (Cl. 15-119) The object of our present invention is to devise a novel construction and arrangement of a mop of the strand or spaghetti type, and a novel construction and arrangement of extracting mechanism therefor.

The mop strands may be of the conventional strand or string type, but preferably the strands are of tubular plastic with a cotton or nylon core, and are removably carried in a mop head connected to the handle or a continuation of the handle.

A further object of the invention is to devise novel means to move a roller carrying extractor in a substantially straight forward path, at the completion of such forward path move the extractor outwardly out of the path of the mop strands, return the extractor at an angle to its forward path, and finally align the extractor in starting position with the rollers positioned to engage opposite sides of the strand assembly.

A further object of the invention is to provide novel extracting mechanism having a head carrying spaced rollers, one of which consists of spaced sections having tensioned members to snap over the handle or a continuation thereof to cause the rollers to be in the starting position of the extracting operation and positioned to engage opposite sides of the strand assembly during the forward extracting pass. The extracting operation is controlled by a sleeve slidable on the mop handle.

With the foregoing and other objects in view as will hereinafter clearly appear, our invention comprehends a novel mop and novel extracting mechanism therefor.

It further comprehends a novel construction and arrangement of extracting rollers and novel means to effect their forward and return movements and their alignment with the mop strand assembly.

For the purpose of illustrating the invention, we have shown in the accompanying drawings a preferred embodiment of it which we have found in practice to give satisfactory and reliable results. It is, however, to' be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and the invention is not limited, except by the scope of the appended claims, to the exact arrangement and organization of these iustrumentalities as herein set forth.

Figure 1 is a perspective view of a mop and extractor mechanism, embodying our invention.

Figure 2 is a longitudinal section on line 2-2 of Figure 1.

Figure 3 is a longitudinal section showing certain of the component parts in a diiferent relation from that seen in Figure 2 and showing some portions in elevation.

Figure 4 is a section on line 44 of Figure 1.

Figure 5 is a section similar to Figure 4, but showing the extractor rolls in section and passing over a portion of the socket.

Figure 6 is a section on line 66 of Figure 2.

Figure 7 is a section on line 77 of Figure 2.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

The mop strands 1 are mounted in a U-shaped carrier strip 2 by means of a U shaped bolt 3 having threaded ends which pass through the strip 2. The sides of the strip 2 are preferably compressed against the mop strands. The strip 2 is removably secured in a slot 4 of a mop head 5.

The mop head is apertured to receive the ends of the bolt which are provided with nuts 6 to lock the strand carrying strip in the slot of the mop head. The front end of a tubular mop handle 7 is fixed in any desired manner to the socket portion 8 of the mop head and inwardly of the mop head the socket portion is of reduced thickness as at socket portion 8 in order to better cooperate with the extracting mechanism as will later be fully explained.

The extractor mechanism has a head 9 in the form of a U-shaped member to provide side arms having slots 10 which provide clearance for the movement of a bearing rod 11. The ends of the bearing rod 11 are fixed to the sides of a U-shaped spring 12 which extends at 13 over the top wall of the head 9 in an outwardly curved condition and fixed to the extractor head by a centrally located screw 14 to provide an adjustable tension for an outer extractor roll 15 which is freely rotatable on the bearing rod 11. The screw 14 serves as an adjustable fastening device to retain the spring 12 on the extractor head and adjust the tension of the spring.

A sectional inner roll assembly is spaced from and parallel to the outer roll and has

roll sections

16 and 17, each of which are of the same construction and assembly so that a description of one will suffice for both. Each roll section has a passage through it of differential diam eters as at 18 and is freely rotatable on a bearing rod 19 which extends through the sides of the extractor head and is fixed therewith by a screw 20. The outward movement of such bearing rod is limited by a shoulder 21 contacting an internal shoulder 22 in the passage 18.

Each roll section has a cone 23 slidable in its passage 18, and each cone has a stem telescoping into a bearing rod 19. A spring 24 tends to move a cone inwardly. The stem has a slot and pin connection at 25 with its bearing rod to prevent rotation of the cone in its passage.

An extractor handle 26 is fixed to the extractor head 9, and this handle 26 is preferably non-circular in cross section and is slidable in a non-circular aperture in a guide 27 pivotally mounted at the forward ends of links 28, the inner ends of such links being pivotally connected with a split ring 29 fixed in any desired manner to the mop handle intermediate the ends of the'extractor handle and of the mop handle.

The inner end portion of the extractor. handle is offset to provide an operating member 30 pivotally connected with a sleeve 31 slidable on the mop handle. The mop handle preferably has a depressed groove 32 which acts as a guide for the longitudinal movement of the extractor handle.

When the mop is being used for surface cleaning, the mop strands contact the surface and the mop handle inclines upwardly and rearwardly from the strands to the hand of the operator. It will thus be clear as shown in Figure 1 that the closed portion of the extractor head and the single roll is at the top, and the sectional roll is at the bottom of the head. When the extractor head is moved towards the socket portion 9, the sectional rolls can pass over such socket portion.

The operation is as follows:

Assuming that the component parts are in the position seen in Figure 1 and it is desired to extract the water from the mop strands, the operator slides the sleeve 31 forwardly causing the mop strands to be compressed between the upper roll and the inner sectional rolls and Patented Jan. 21, 19585- ic'the "extractor .head :to :be .advanced beyond the mop strands. The ,operatonnext presses -theextractoiuhandle portion 30 towards the sleeve 31, thereby causing the head 9 to move laterally or upwardly out of the path of the mop strands as shown :in Figure 3, the iinlzs .23 swinging outwardly. "-With the handle portion depressed theoperator.draws the sleeve 31 rearwardly until the nectionalsrolls are in the position seen in Figure .4 andlocated above thereduced width 8 of the mop handle. The operator now holds the mop handle in one hand and with the other hand presses on the portion 26 of the 'extracton-handle or the extractor head towards the mop handleand the tensioned cones pass over the red-uced'Width S, see .Figure and into starting position shown in Figure 1 with the extractor rolls properly aligned ,forlthe forward extracting pass. The reduced width-8 is preferably converged at the top and bottom. When lthepartstare inithe Position shown in Figure 1, they arearranged-for-normal operations of mopping a floor. The tubular handle 7 is secured at its forward end to thesocketportion 8. Therefore, the sectionalrolls '16 and dlcanx-besconsidered forming the inner roll, and the roll 15:can be considered as the outer roll.

Having thus described our invention, what we claim and' desire to secure byzLetters Patent is:
