4 Claims.

This invention relates to what are known as dry or dust mops which are used Without Wetting to pick up dust and dirt on the floor. As now made, when a certain amount of dust has been picked by the fringe of the mop head, it is necessary to take the mop outdoors or to stick it out of a window or a door and to shake it or strike it against something. This is not only inconvenient but damages the mop, allows the dust to blow back through into the room and into the face of the operator and is generally inefficient.

The purpose of this invention is to provide a beating attachment for such a mop comprising a comb or saw, preferably with two sets of parallel teeth, which can be caused to beat back and forth through the fringe or fringes of the mop by moving back and forth a handle slidable on the mop stick. The comb and its Operating parts can be locked out of the way so that they will not interfere with the usual'operation of the mop and it can be attached to and used with a mop having either a fixed or a pivoted head.

In the drawing,

Fig. 1 is a side elevation of a dry mop with my device attached.

Fig. 2 is a plan view of Fig. 1 and Fig. 3 is a detail showing one end of the comb.

Fig. 4 is an enlarged sectional view on the line 44 of Fig. 1 and Fig. 5 is an enlarged sectional view on line 5-5 of Fig. 4.

Fig. 6 is an elevation similar to Fig. 1 but from the opposite side with the parts in different positions and with the head H pivotal on stick S.

Fig. '7 is a plan view of a modification of the head and comb.

In Figs. 1 to 5 of the drawing is shown a mop with a straighthead H pivoted at l2 to a stick S but fixed in position by a tightening nut I3. This head H carries three rows 4|, 42, and 43, of fringe the fringe 4| being the longest, 42 the next and 43 the shortest. Head H is shown as made of sheet metal with bent up ends Hi, It, and ears II, II, there being holes through the ears H, II, for a pivot pin bolt l2 which passes through stick S and carries a tightening nut 53 whereby the head H can be fixed in one position as in Fig. 1 or can be pivotally mounted on stick S as shown in Fig. 6.

The stick S at its forward end I has a pivot hole 2 through which the pivot pin bolt [2 passes and along its bottom 3 is flattened, the rest of the stick preferably being round.

C is a comb which, as shown, is made of sheet metal which has a fiat body 20 pierced by slots 25, 25, and at the front and back is bent up to form rows of saw teeth 21 and 22, there preferably being a cut away part 23 to fit the stick S.

The ends 24, 24 of comb C are bent up and through them are comb moving arm holes 26, 26.

P, P, represents pivot arms which, as shown go through the slots 25, 25, and. back of 20 at 50 and serve as hangers to pivotally carry comb C and to keep it from side swinging. Each arm P has one free end 52 bent in and passed through a hole I4 in a bent up end H] of head H.

A is a comb moving arm shown as made of a single metal rod bent at 6| to pass through holes 62, 62, in ears 63, 63 of slidable handle K.

Ears 63, 63, project up from handle K and. 16 is an adjusting bolt to regulate'the distance between them. This bolt 10 also serves as a pivot for knob 64 and cam lock 65.

Each end of comb moving arm A [passes through a hol 26 in an end 24 of comb C and the part 6| is shown as being integral and uniting the sides 60, 60, of arm A.

As shown, slidable handle K is made of sheet metal so shaped as to fit snugly on stick S and at the bottom adjoining the part 3, it is fiattened as at 66. The part 64 of handle K is shown as a wooden knob carried by a shank 68 and eccentric pivoted between the ears 63, 63, on the bolt III. This part 65 is formed as a cam lock or as an eccentric with a base 61 of such character that when the knob 64 is moved forward, the cam face 61 will be clear of the stick S as shown by dotted lines in Fig. 5 thus allowing the handle K to be moved back and. forth on the stick S.

When it is desired to lock the parts in the usual position, the knob 64 is pulled toward the operator engaging face 61 with the stick and locking the handle K in position. In this manner, when the comb device is out of use and the fringe is being used to pick up dust, the handle K and comb C are held out of the way so that the comb C will not scrap on the floor when the mop is being so used. Cut away part 23 allows comb C to fit up snugly under stick S.

As shown in Fig. 6, if the tightening nut I3 is loosened so that head H pivots on stick S, the movement of the comb C pivoted to head H is compounded with the movement of the head H itself which is pivoted to the stick at 2 on [2.

Fi 7 is a plan View of a triangular head L pivotally attached to a stick T by a bolt l6 and a nut IS. A comb D similar to comb C is carried by the pivot arms R, R, and is moved back and forth as by comb moving arms B, B.

I claim:

1. The combination in a dust mop comprising a stick with a mop head pivoted at one end thereof and including several rows of webbing material at the bottom of the head to pick up dust and means to hold the head in predetermined position; of a comb hanger including two comb pivot arms each of which is pivoted on a side of the mop head in line with the head pivot and that end of the stick and which extend through slots in a comb device and are integrally connected behind the comb device; such comb device, including said slots and connected parallel rows of saw teeth, pivotally hung on the hanger between the other ends of the comb pivot arms; comb moving arms pivoted on each side of the comb device and extending back and pivoted to a handle which is slidable on the stick; and a catch on the handle to keep it from sliding when the mop is being used for dusting.

2. The combination in a dust mop comprising a stick with a mop head pivoted at one end; of a comb hanger including two arms pivoted on a side of the mop head outside the head pivot; a comb device, including connected parallel rows of teeth, pivotally hung on and between the ends of the comb pivot arms; comb moving arms pivoted on each side of the comb device and extending back and pivoted to a handle which is slidable on the stick; and a catch on the handle to keep it from sliding when the mop is being used for dusting.

3. The combination in a dust mop comprising a stick with a mop head pivoted at one end and means to hold the head in predetermined position; of a comb hanger including two arms pivoted at one end on a side of the mop head in line with the head pivot and which extend at their other ends through slots in a comb device, such other ends being integrall connected behind the comb device; such comb device, including said slots and connected parallel rows of saw teeth, pivotally hung on the hanger between the other ends of the comb pivot arms; comb moving arms pivoted on each side of the comb de vice and extending back and pivoted to a handle which is slidable on the stick.

4. The combination in a dust mop comprising a stick with a mop head at one end thereof and including a fringe of webbing material at the bottom of the head to pick up dust; of a fringe beating device including two arms each of which is pivoted at one end on the side of the mop head; said device pivotally hung on and between the other ends of the arms; and an arm extending from the fringe beating device to a handle which is slidable on said stick.
