CLAUDE L. ROBINSON, OF PRINCETON, FLORIDA.

WINDOW CLEANING DEVICE.

Specification of Letters Patent.

Patented Feb. 25. 1913.

Application filed May 4 1912. Serial No. 695,083.

To all whom it may concern Be it known. that I, CLAUDE L. ROBINSON, a citizen of the United States, residing at Princeton, in the county of Dade and State of Florida, have invented new and useful improvements in Window-Cleaning D e vices, of which the following is a specification. 7

This invention relates to window cleaning devices and particularly to devices designed for use upon street cars, automobiles or like I windows where it is desirable to maintain a perfect transparent condition of the Window in immediate line with the face of the driver or operator.

An object of the invention is to provide a window cleaning device which may be slidably mounted upon a window frame and which will be automatically held in an operative position at one end of the frame soas to permit of its being readily drawn across the window as the occasion may demand.

A still. further object of the invention is to provide a window cleaning device which will include an elastic gripping element and means whereby the element. can be rocked with relation to the window and automatically brought into operative contact with the window or movement of the device in one direction and then automatically moved toa disengaged position on movement of the device in another direction.

In the drawing forming a portion of this application ,and in which like letters of reference indicate similar parts in the several views :Figure 1 is a front view of a windowshowing the application of the cleaning device thereto. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a perspective view of a portion of the carriage. Fig. 4 is a'section taken on line 4-4 of Fig. 1 drawing the cleaning strip in contact with c transparent panel of the window. Fig. 5) is a similar view showing the cleaning strip disengaged from the transparent panel of the window.

The cleaning device preferably comprises :2 carrier which includes a rod 1 which is disposed vertically upon the window frame itconventionallyshownhercin. 'lhisrodhas socket. nuuubcrs 2 secured thereto at its ends and as illustrated the socket members are provided with slots 3 through which combined guide and stop pins 4 of slidable stub shafts 5-extcnd. These shafts have port-ions.

extended into the sockets 2 and outwardly of the sockets they are provided with outwardly diverging arms 6 upon which rollers 7 are journalcd. being adapted to travel upon the tracks 8 for a purpose to be hereinafter described.

A sleeve 9 is mounted for-rocking movements upon the rod 1, being preferably provided with extension 10 to which is secured an elastic cleaning strip 12. Fastenin screws or the like 13 are extended througi the strip 12 and extension 10 so as to hold the-former properly associated with the lat.- ter. The socket portions 2 are provided with steps 14 with which the sleeve 9 is adapted to contact whereby the movement. of the latter is limited in one direction.

Brackets 14 are secured to the rails S and journaled therein are pintles 15 of a roller 16. This roller has one endof a helical spring 17 secured therein while the opposite end of the spring is secured to one of the pintlcs so that under the action of the spring the roller will tend to revolve in one direction. Cords 19 are secured to and wound around the opposite ends of the roller and extended through passages 20 in the extension 10 of the sleeve 9. One cord is referably extended through one of the sir e bars of the window frame and operatively passed through guide eyes 22 which extend from the frame while the free terminal of this cord is detachably connected with a suitable cleat or retaining device 23 near the lower edge of the frame. The other cord 19 is secured to the just described cord as at 24: whereby when the cleat engaging terminal 25 is pulled both the cords may be unwound from the roller and drawn across the transparent 'panel of the window. Each cord is provided with a pair of spherical objects or sleeve 9 in a direction to cause the strip 12 to move. in spaced relation to the said transparent panel of the window. When the terminal 25 is released the (-ordswill be drawn back upon the roller under the tension of the spring 16. The bodies 26 will be made to engage with the extension 10 of the sleeve 9 so as to rock the same in one direction on the rod '9 with a resultant engagement of the strip 12 with the transparent panel of the Window. Relatively strong springs 28 are mounted in the socket portions 2 of the rod 1. These springs are made to engage -against the inner ends of the stub shafts 5 in a manner which will cause them to be forced outwardly. This causes the rollers 7 to effectually engage against the rails 8 hereinbefore described.

I claim A Window cleaner comprising parallel tracks, a rod extending at right angles to the tracks and provided at its ends with socket portions, traveling supports movably engaging the tracks, and having portions yieldingly fitted in said socket portions, means for moving the rod in two directions, and a rocking strip carried by the rod and adapted to engage against the window pane on movement of the rod in one direction.
