FLOOR DUSTER AND POLISHER.
Specification of Letters Patent.
' Patented Sept. 29, 1908.
Application filed September 10, 1906. Serial No. 333,920.
useful Improvements in Floor Dusters and.
Polishers, of which the following is a specification, reference being had therein to the accompanying drawing.
My mvention relates to an improved floor duster and polisher, and I declare that the following is a full, clear, concise and exact description thereof sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like letters and numerals refer to like parts throughout.
' My device comprises a mechanism having a frame and a handle, the frame being rovided with two' rollers which are 0 erate by the turning of the handle, and a 0 0th being mounted on the rollers and adapted by the turning of the same to be passed from one roller to the other.
The detail of the construction and the method of operatin the device will be pointed out in the speci cation and illustrated in the drawings. 1
In the drawings Figure 1 is a front view of the device, one end of the floor or forward roller being shownin section. Fig. 2 is a back view. Fig. 3 is a artial side view on the line ac-w of Fig. 2. Fig. 4 is a front view of the ends of the rollers showing details of construction at the end of the front or floor roller, and Fig. 5 is a like view of these parts in diflerent position, Fig. 6 is a detail view of the mounting of the sprocket-wheel.
The device consists of a frame 1 comprising a head piece and two lateral extensions between which are mounted the rollers which carry the cloth A or other cleaning material.
The exterior of the frame is bound around certain arts with a guard or rubber 2 for the protection of the furniture, and the forward end of the righthand section of the frame is bent inward, as at 3, so that the bearing on the roller is sunken within the end of the roller which is made up, in this instance, of the core 4 of wood or other suitable material with a suitable cap for the mounting at each end, and is covered with a thickness of felt 5 or other soft material, which at the end referred to projects beyond the cap, asin'dicated in Fig. 1, to protect themop-board or indicated in Fig. 2.
the furniture from marring by the frame as the cleaner is passed to and fro. The other roller, 6, is likewise of wood, havin suitable ca s for the mounting at each en These re ers are suitably revolubly mounted in the frame.
The handle 7 is mountedin a ferrule 8 i which has a stud which extends through the frame 1 and block 9 revolubly supporting the ferrule and stud. The ferrule is rovided with inclined steps 10 against w ich the spring 11 engages to permlt the handle and ferrule to be turned in one direction only, as The stud which extends through block 9 carries the beveled pinion 12 w ich engagesv the beveled gear 13 mounted on the shaft 14 which is supported 7 on block 15 and in the frame, carrying at the end adjacent to the frame the sprocketwheel 16 which carries the chain 17. The journal at one end of the roller 6 loosely carries a sprocket-wheel 18 and a spring 19 which bears against the wheel and the cap on the roller, whereby the wheel, when actu: ated by the chain, turns the roller through friction of the s ring, but which friction may be overcome w en the front roller is fast so that it cannot pay off any cloth. On one end of the roller 4 is a sprocket-wheel 20 on which the chain also rides, so that as the handle is turned in the direction indicated in V Fig. 2 it normally turns the rollers 6 and 4 in the direction indicated in that figure.
The mounting of the sprocket-wheel 16 is adjustable to permit changing the tension of the chain.
' 21 is a screw-headed j ournal bearing in the frame, held in position by any suitable means such as a set-screw in the frame (Fig. 2). This journal bearing has a bore eccentric to its axis in which passes the shaft 14 on which the sprocket-wheel 16 is fixed. As the bore is eccentric the turning of the ournal bearing changes the tension of the chain on wheel 16.
The sprocket-wheel 20 is loosely mounted on the journal at one end of roller 4 which is longer than the hub of wheel 20 to allow space between the wheel and the frame for swing latch 22. The opposite face of the sprocket wheel has laterally projecting ratchet teeth 23 arrandged around the wheel, 7
and the cap on the en of roller 4 has one or more teeth 24 to engage the teeth 23.
25 is a spring pressing s rocket-wheel 20 into said engagement. T e latch 22 nor- 'rolled over the cloth which gathers it onto In operation the cloth is at first wound on.
the ground or floor roller. This may be con veniently done by laying the cloth on the floor and bringing the near end up between the rollers and fastening it by suitable means provided thereon for that purpose, such as hooks a. The machine is then passed or the floor roller, when the other end is secured to the upper roller by like hooking means. The cloth being then on the forward roller, the device is passed over the surface to be cleaned and when the portion of the cloth in contact with the floor has become soiled the handle is turned to the left. This turns shaft 14 and sprocket-wheel 16 to the right as seen in Fig. 3. This turns the floor or lower roller in a right-hand turn as seen in that figure and theupper one in a left-hand turn winding the cloth on the upper roller. The friction between the sprocket 18, spring 19 and roller 6 operates to turn that roller.
-Since the latch 22 is down and sprocketwheel 20 thus crowded against the end of roller 4 the teeth 23 engage with teeth 24 and turn the roller because of the closeness of contact and not because the right surfaces of the several teeth lock them together, those teeth being arranged as they are to prevent roller 4 from turning and unwinding the cloth when the machine is drawn backward.
It is obvious that as the cloth passes from one roller to the other the rate of speed with which each roller turns varies, instead of being even as would be the case if they were constantly of the same size. The sprocket- .wheel 18 is, therefore, adapted to turn roller 6 at a maximum rate, but the spring friction of that sprocket on the roller is provided so that when the floor roller turns at less than the maximum rate the upper roller will turn only as fast as the cloth is given off from the lower roller and not at the rate which the sprocket-wheel 18 turns. When the cloth has all been passed to the roller 6 it may be rewound on the forward or floor roller by swinging the latch 22 out of place and turn- 'ing the forward or floor roller in the opposite direction, or by pushing the machine over the floor the teeth on the cap at the end of that roller riding over the lateral teeth on the sprocket-wheel 20. If instead of rewinding claim as new and desire to secure by Letters Patent, is:
1. A cleaning machine comprising a frame, a handle attached thereto, rollers journaled in the frame, a cloth attached to the rollers, means mounted between the handle and the rollers for actuating the rollers by rotating the handle whereby the cloth. is'wound from one roller onto another, in combination substantially as set forth.
2.
