. MOP SHAKING DEVICE Application June 5, 1936, Serial No. 83,684

6 Claims.

This invention relates to an improvement in dust mops or similar articles of the character .shown in my U. S. Patents Nos. 1,993,336 and 1,996,056, and relates particularly to a means by which the mop may be vigorously shaken or vibrated to cause the accumulated dust and dirt to be dislodged and if desired, directed into a receptacle or onto a paper.

The object of the invention is to provide a mechanism of simplified construction and of few "parts whereby a rapid, vigorous vibrating movement may be imparted to the mop head causing it to effectively shake the dust and dirt from the mop strands.

A further object of the invention is to provide a mechanism of the character described having no projecting parts or elements likely to come in contact with furniture and do damage to the same.

Another object of the invention is to provide a shaking mechanism composed of relatively few parts unlikely to become injured or damaged by the shaking operation, and also unlikely to become worn during the normal use of the mop.

In the accompanyingdrawing wherein several embodiments of the invention are shown, Fig. 1 is a sideelevation of the mop with parts in sec- .tion showing the improved shaking mechanism; Fig. 2 is a sectional View on the line 22 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a plan view of the centerportions or yoke of the mop head frame or rocking member showing the connections for the mop shaking mechanism; Fig. 4 is a front view of the lower end of the mop stick showing the guide pulleys and mounting therefor; Fig. 5 is a sectional View of the lower end of the mop stick showing a modified form of housing for the guide pulleys; and Fig. 6 is a view of the structure shown in Fig. 5 taken at right angles thereto.

The mop body or head consists of the strands I held together in the conventional manner by the stitched fabric binding 2 of tubular construction, which fits over a substantially triangular or heart-shaped frame 3, composed of wire, metal rod, or of sheet or strip metal. The frame 3 is provided with an inwardly bent centrally disposed narrow loop or yoke portion 4 to parts of which the various operating elements of theshaking device as wellas the lower end of the mop stick housing '5 attaches. The housing shown in detail in Figs. 1 and 4, is composed of two like halves whichwhen placed together form a tubular socket member into which the lower end of the mop stick "6 is fitted. The two halves of the housing 5 are held together by bolts or rivets l which also pass through the stick near its lower end and also secure the stick in the housing. At its lower end each of the halves of the housing 5 is provided with a downwardly projecting lug or car 8, the two lugs being pivctally mounted on a cross-bar 9 extending between the sides of the yoke 4 of mop frame 3. Suitable washers or spacing members it? hold the lugs properly spaced on the cross-bar El and enable the mop frame to be freely pivotal in the lugs 8. The housing 5 is also provided with two pairs of projecting cars it and i2 constituting pulley bearings. pair of cars designated at H a pulley i3 is rotatably mounted, while between the two cars l2 a similar pulley I4 is mounted.

A flexible two-part cable or cord i5 has its lower end It connected to a cross-bar ll at one end of the yoke 4, and its other end it secured to the end l9 of the yoke l. Said cable has one side or leg 4! extending upwardly behind the pulley i3 and it is guided in a longitudinal groove 2! in the stick 5. Cable i5 passes around a pulley 22 rotatably mounted in a recess 23 located in the handle 5 at the upper end of groove 2! and is attached at 21 to sleeve 26. The side or leg 42 of the cable extends upwardly behind pulley i4 and is movable in groove 2i! located diametrically opposite groove 2| in stick 6. At its upper end leg 42 of the cable is secured at 28 to the sliding sleeve. or actuating member 2E5. Pulley 22 is covered and thereby concealedby a tubular bumper 24 (preferably of rubber) and a similar bumper 25 also surrounds the stick and is secured thereto at a distance from that shown at 24. The tubu-; lar sleeve 26, constituting an actuating member surrounds v the stick and is manually slidable thereon and has its sliding movement limited by the bumpers 24 and 25.

To-operate the mop, it is merely necessary to hold the stick in one hand and grasp the actuating member 26 with the other, moving the actuating member or sleeve vigorously back and forth between the spaced bumpers E i and 25. As the actuating member 26 is thus reciprocated, it moves the two-part cable 15 back and forth over pulleys i3, i4 and 22, thus rapidly and noiselessly vibrating the mop and dislodging the accumulated dust and dirt therefrom.

In'the structure shown in Figs. 5 and 6 is shown a two-part housing composed of the halves Bil united by rivets l which also hold the end of stick 6 in the housing. The halves 3B of the housing are each recessed or depressed as at it, a rivet 3| connecting saiddepressed portions and In the constituting a bearing on which a double-grooved pulley 33 is rotatably mounted. The side or leg 4! of the cable l extends in groove 2| and rides in one groove of the pulley 33, passing under the pulley and extending to the right (when viewed as in Fig. 6) and connects at l8 to the frame portion IQ of the mop head. The other side or leg :32 of the cable engages the second groove in the pulley and extends under said pulley to the left (Fig. 6) and connects at I6 to cross-bar ll of the mop head frame. The halves 30 of the housing are recessed or cut away at 43 to avoid interference with the cable as it moves back and forth over the pulley.

The structure of Figs. 5 and 6 operates similarly to that of Figs. 1 to 3 inclusive. That is to say, by rapid reciprocation of the actuating member 26, the cable l5 moving over

pulleys

22 and 33, smoothly and noiselessly rocks the mop head back and forth with a rapid vibratory motion, causing the dust and dirt to be shaken from the strands I. Pulleys I3, [4 and 33 and their respective pivot pins are always available for occasional oiling to insure smooth, noiseless operation of the shaking device.

One of the objections often urged against mops provided with shaking devices is that such shaking devices add considerable weight to the mop thereby fatiguing the user. By the construction herein disclosed this objection is obviated since the relatively simple arrangement and light weight of the few parts employed produces a shaking device without adding noticeable weight to the mop. The operating cord or cable I5 is, in the disclosed construction, visible and accessible at all times thereby enabling it to be easily inspected for signs of wear and speedily replaced when necessary without requiring dismantling of the pulley housing. The exposed end portions l6 and I8 of the cord enable any slight slackness which may occur in the cord after considerable use, to be taken up. Pulleys I3, [4 and 33 are exposed and available for easy oiling and replacement when wear occurs. Additionally, the simplicity of the construction employed permits the shaking device to be incorporated in Y a mop structure at relatively slight expense thereby enabling the improved mop to be sold at a price attractive to purchasers.
