LONDON, ENGLAND.

WINDOW-CLEANER.

SPECIFICATION forming part of Letters Patent No. 462,905, dated November 10, 1891.

Application filed March 6, 1891- Serial No. 384,042- (No model.)

T0 at whom it may concern:

Be it known that we, CHARLES RoMLEY ALDER. WRIGHT, D. So, F. R. S., consulting chemist, and PRISOILLA AGNES WRIGHT, wife of the same,both residing at 3 Castellain Road, Maida Vale, London,'in the county of Middlesex, England, subjects of the Queen of Great Britain, have invented certain new and usefulApparatus for Dusting, Cleaning, or Tashing Walls, Windows, and Elevated Surfaces, of which the following is a specification.

The apparatus consists of a brush or cleaning-pad supported by a rod which is attached by a flexible joint to a stand or support in such a way that this rod is normally maintained in an approximately vertical position, but can be oscillated to and fro about the joint so as to cause the brush to travel to and fro in a nearly horizontal path. Provision is also made for setting the brush or cleaningpad successively to different distances from the ground so that a large surface of wall may be brushed or cleaned.

Ordinary long-handled brooms, brushes, mops, and cleaning-pads such as are usually employed for dusting, wiping, and cleansing ceilings, cornices, and upper portions of the walls of dwelling-rooms and other buildings and such like purposes are very laborious to use and greatly fatigue the arms, while the use of lofty ladders to assist in reaching such elevated surfaces for the purpose of cleansing them is attended with more or less risk of over-balancing and falling.

By our invention the labor and fatigue involved in the use of long-handled brushes, &c., are greatly diminished, and the risk of strains arising from the use of such long-han dled brushes or of accidents arising from the use of lofty ladders is completely obviated.

The drawings annexed show examples of apparatus constructed according to our invention.

Figure l is an elevation of one form of the apparatus. Figs. 2, 3, and 4 are elevations of modified forms thereof. Fig. 5 is an elevation of a modified form of the apparatus, in which the stand or base is formed of a short set of steps. Fig. 6 is an elevation of another modification, in which the stand or base is a In Fig. 1, A is a brush carried by a rod B, I

which can be slid upward or downward along a rod 0 and can be held at any desired elevation by the rods B and (J, where they overlap one another, being grasped in the hand of the user. The lower end of the rod 0 is held in a socket which stands up from a metal plate D. This plate rests upon the top of and is secured to four or other number of india-rubber or coiled metal springs E, which at their lower ends are secured to a baseplate F. The springs tend to hold the rod or broom-handle C normally in a vertical position, but allow of its being oscillated to and fro in any direction, as desired.

In Fig. 2 the brush A is carried on the rod B, which may be adjusted upward or downward along the rod C. The lower end of the rod or broom-handle O fits loosely into a cavity in a base-plate F and has four or other number of inclined coiled springs or stout elastic cords E passing from it to the baseplate F, as shown.

In Fig. 3,A is a brush carried by a rod B adjustable vertically relatively to the rod C The lower end of the rod or broom-handle (J is pin-jointed to the base F. In this form two springs IE only need be used.

In Fig. A the joint about which the rod which carries the brush or pad can oscillate is at some distance from the ground. In this case the brush A is carried byarod B which is pin-jointed at B to a rod 0", which can be raised or lowered along a rod 03, which at its lower end is fixed to the base F The rod B is also prolonged downward below the joint B and carries at its extremity a weight G which tends to maintain the rod B in a vertical position.

In Fig. 5 the stand or base F is shown as being formed of a short pair of steps F. The rod 0 is jointed at its lower end to the back of the steps near to the ground and is held normally in an approximately vertical position by springs E passing from it'to the two sides of the top of the steps. The brush A is also represented as being connected to the rod 13 by means of a joint and tightening- ICO screw H which allows of the brush being set vertically, horizontally, or in an inclined position. In Fig. 6 the stand or base is a rectangular frame fitted with a sliding drawer I at the bottom. The rod C is jointed at its lower end to the back of the stand. Two uprights J rise up from the stand and carry a cross-bar J into holes J in which pin check-stops can be inserted to limit the extent to which the rod 0 can be oscillated to and fro. The brush A is carried by the rod B, which may be adjusted vertically on the rod C.

What we claim is 1. The combination of a stand or base-plate, a vertical telescopic or extensible rod carried thereby, means for returning the rod to an approximately vertical position and for normally holding it there, and a brush or cleaning-pad carried at the upper end of the rod and free to move horizontally in the arc of a circle with the telescopic rod.

2. The combination of a stand or base-plate, a telescopic or extensible rod carried thereby and free to be vibrated thereon horizontally,

rod, and means for holding the brush-carry ing rod in an approximately vertical position.

5. The combination of a base-plate, a brush, a brush-carrying rod, another rod, to which the brush-carrying rod is adjustably connected, and springs interposed between this rod and the base-plate and constructed and arranged to maintain the rods in a vertical position or to return them to such position after r they have been moved from it.
