WINDOW-CLEANER.

Specification-of Letters Patent.

, Patented April 17, 1906.

Application filed April 24, 1905. Serial No. 267,024.

.State of Pennsylvania, have invented a new and useful Window-Cleaner, of which the following is a specification. 1

This invention relates to devices used in cleaning windows, and particularly to that class of devices in which both sides of the glass are operated on simultaneously.

The objects of this invention are, first, to provide a device for the said purpose that is adapted to engage or release the erasive ma terial solely by'the operation of s rings; second, to provide means whereby t e distance from the heads to the handle may be adjusted and maintained without the use of screws or extra parts, and, finally, to provide a device of the kind at a moderate expense. These objects are attained by the novel construction and combination of arts hereinafter fully described and shown in the accompanying drawings, in which Figure 1 is a front elevation of the apparatus. Fig. 2 is a side elevation of the same with erasers in position; and Fig. ,3 is an enlarged view of a portion of one arm, showing the means of lateral adjustment.

Similar characters refer to similar parts throughout the several views.

' The operatinghandle 1 has securely attached to it the united extremities or ends 2 of the rods 3 and 3, which are outwardly curved to provide a suitable space between and then formed arallel to each other and lateral with the handle. The rods are of suitable material and so made that there is a constant tension or spring effect tending to force the arms toward each other for the pur-' pose of exerting a uniform pressure on each side of the window-pane being operated upon, as shown in Fig. .2. The outer surfaces of the rods are grooved or indented transversely to their length, the grooves 4 4 4* 4 being angular or curved in shape, equally spaced, and oppositely located. The tubes 5 and 5 are 0 a suitable size to freely slide over these rods and sufiiciently strong to' convey the spring effect of the forked rods. The ends of t e tubes near the handle are provided with slotted openings 6 and 6 to permit of a slight flexibility of the tube'sides having the catches or detents 7 and 7, which are turned inwardly near the lower ends on one side of the slotted tube only. The shape of these detentsapproximate that of the recesses in the rods with which they coact in maintainin the position laterally ofthe tubes with rel erence to the forked rods. The outer ends of the tubes 5 and 5 are secured to the plates. 8 and 8, which form parts. of the clamps for holding whatever cleansing or erasive material that may be used, as rubber, sponges, cloths, &c. On these plates are pivotally mounted upper clamping members 9 and 9, having the edges 10 and 10 in register with the inner edges of the plates. They are further provided with lever-handles 11 and 11 for raising the clamping edges from the lower plate and also provided with springs 12 and 12 which maintain a constant ressure normally between the clamping e ges, securely holding whatever may be placed between them.

In operation the clam s are supplied with a suitable cleansing me ium, the fork-arms spread to permit the sash to pass between the material held in the clamps, whereupon the tension causes the clamps to press firmly and evenly on both sides of the glass at points exactly o posite, so that there is no undue straln or ten encyeither to break the glass or loosen it from the sash. Areciprocating action given to the handle, manipulating it, as may be necessary, from side to side, expeditiously cleans the glass, the wipers reachin to any point within the boundary of the sas Should the sash be large, the tubes can be drawn outwardly, extendlng the reach of the clamps to suit the varying conditions.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is l 1. In a device of the class described, the combination with a suitable handle, of a pair of rods affixed therein, spread beyond and extending laterally to the handle, parallel to each other, and having a series of regularlys aced indentations on their outer sides, close-fitting tubular sleeves slidable on said rods, having catches formed at their lower ends adapted to engage with the indentations in said rods and clips arranged at their upper ends, all substantially as shown and described.

2. In a device of the class described, the E In testimony whereof I have signed my combination with the handle of the rods 3 name to this specification in the presence of and 3, having the indentations 4, 4 4 and I two subscribing Witnesses. 4, the sleeves 5 and 5*, having the catches 7 SAMUEL R.
