SPECIFICATION forming part of Letters E'atent No. 541,992, dated July 2, 1895.

Application filed October 15, 1894. Serial No. 525,882. (No man.)

To all whom it may concern.-

Be it known that we, WILLIAM H. CLOUD and JOHN W. LAPPIN, citizens of the United States, residing at Kokomo,iu the county of Howard and State of Indiana, have invented a new and useful Improvement in Rotary Wipers, of which the following is aspecification.

Our invention relates to an improved device for wiping bar-counters and floors.

The object of our improvement is to take up water and slops from a bar-counter or floor without the use of the ordinary handcloth or mop.

The accompanying drawings illustrate our invention.

Figure 1 represents a vertical transverse section of our wiper. Fig. 2 represents aplan of the same, having the top of the casing broken away to show the interior.

In the drawings, 2 indicates a shaft, preferably of wood and provided with a series of wipers, consisting of longitudinal flexible ribs 3,projecting radially from the periphery of the shaft. Said wipers are formed, preferably, of rubber and are made wedged-shapedin crosssection, the thicker edges being next to the center of the shaft, and they are secured to the shaft in dovetailed longitudinal grooves formed in its periphery.

Shaft 2 is provided at each end with short journals 4: 4, to which are secured a pair of driving-wheels 5 5, each of which is provided,.preferably,witha rubber tire. Mounted upon the journals 4 4: is a casing 6, formed, preferably, of sheet metal inclosing the shaft and its ribs and extending backward to form a reservoir 7.

Casing 6 is closed on all sides except anarrow opening 8 on the bottom immediately beneath the shaft 2. Secured between the side walls of the casing at one side of the opening S-is a cross-bar 9, to which is attached a scraper 10, the lower edge of which is adapted to yield to slight inequalities of the surface of the floor or counter, and is formed, preferably, of rubber. On the other side of said opening the casing is bent to form a guard-plate 11, which projects into the path of the outer edges of the wipers 3, so that each of the wipers, as it approaches the openof the scraper.

lines in Fig. 1, until it reaches the front edge of scraper 10, the purpose being to prevent the escape of the water beneath the edge of the wiper when it moves toward the scraper. That surface of cross-bar 9, which is the next the shaft, is formed substantially concentric therewith, and is arranged at such a distance therefrom that the free edges of the wipers will press closely against it and are slightly bent backward in passing over it.

The rear edge of the casing 6 is supported upon a single caster wheel 13, which is mounted in a standard 14, which is secured, so as to be vertically adjustable in a bracket 15, projecting from the casing by means of check-nuts 16 and 1 7.

When the device is designed to be used upon a table or counter, the casing is provided on its upper side with a handle 18. If to be used on the floor, a bail provided with a suitable long handle is mounted upon the journals at 4 in the manner of carpet-sweeping devices. Said bail is shown in Fig. 1 in dotted lines.

The operation of our device is as follows: The caster-wheel 13 is adjusted at such a height that when the driving-wheels and the caster-wheel rest upon aplane surface the forward edge of scraper 10 will press closely against the same surface. The device being pushed forward on a wet surface in the direc tion indicated by the arrow,Fig. 1, a wave or ridge of water is raised in front of the edge At the sametirne shaft 2 with its wipers is revolved by the frictional contact of the driving-wheels with the surface over which the device is moving, so that the wipers, as they approach the under side of the shaft,

are first bent backward by the engagement the scraper, thus picking up the wave raised by the scraper and carrying it upward along the front edge of bar 9 until reaching the top edge of the bar the Water is thrown by the straightening of the Wiper backward into the reservoir. When-the reservoir has become nearly filled, it is emptied through the opening 19 in the side of the casing.

We claim as our invention In a wiping device, the combination of the revoluble shaft provided with a series of Iongitudinal, radially arranged, flexible wipingribs, the casing mounted upon said shaft and extending backward to form a reservoir behind the shaft, the cross-bar secured to said casing and carrying at its lower edge a flexible scraper which projects below the casing, the guard-plate secured to the casing opposite said scraper and projectinginto the path of the wipers, as set forth, and the pair of driving-wheels arranged to support the casing and connected to the shaft so as to impart a rotary motion thereto, all arranged to cooperate substantially as set forth.
