WINDSHIELD CLEANER;

Application filed August 10, 1922. Serial No. 581,012.

To all whom it may concern:

Be it known that I, GEORGE N. Ham, a citizen of the United States, residin at city and county of San Francisco and tate of California, have invented certain new and useful Improvements in Windshield Cleaners, of which the following is a specification.

Pivotally mounted wind shield cleaners as at present manufactured, cover but a limited area of the wind shield and when in use render but a small portion of the shield in a condition to afford a drivin or road sight opening. Cleaners are provi ed which move in a horizontal path acrossthe shield, but the operation of this type of cleaner is diflicult.-

The present invention relates to an im-.

proved type 05 wind shield cleaner, whereair of f lcrumed arms are employed mova Is in an arcnate path and which are connected at their free ends by a conven- The operation of the arms causes a movement of the wiping element in an arcuate path while assuming a horizontal position and thereby operating over a considerable area of the shield. An object of this invention is to (provide a ty of structure, which is adapte for manna movement in one direction and automatical return movement in another direction, also to .provide a structure wherein the pivoted arms are of approximately duplicate character and wherein an additional cleaning elementis pivotally connected to one end of the main element and is in turn pivotally mounted at one end to swing in a dp its associate arm.

. With the above mentioned and other objects in view,the invention consists in the I novel construction and combination of parts and minor detai of'and wherein, Y e

Figure 1 is a view in elevation of the wind shield cleaner mounted on a conven-.

hereinafter described, illustrated in the accompanying drawin ,and set forth in the claims hereto appen ed; it being understood that various changes in'the form, proportion of'construction may-be resorted to withinthe scope of the appended claims. i

To more comprehend the invention,

attention is directed to the accompanying drawings illustrating one embodiment theretional vehicle wind shield and viewed from the interior of the vehicle.

ath corresponding to that of Figure 2 is a view in detailed elevation of the cleaner in its normal position.

Figure 3 is a sectional view of a portion of a wind shield illustrating the mounting for the supporting arms and in this embodiment illustrating, the'handmcrank for operating the construction.

Figure 4 is a view similar to Figure 2 f illustrating the wind shield cleaner in full operative position.

Figure 5 is a view in elevation of the s ring return arm illustrating the mounting p ate therefor.

Figure 6 is a view in side elevation of the arm illustrated in Fi re 5.

- Figure 7 is a view in side elevation of the cord guide secured to the windshield frame. Figure 8 iso view in plan of the same element and Fig. 9 is a perspective view of the clamp for securing the cord to an operating pedal.

Referring particularly to the several views of the drawings wherein like characters designate corresponding parts 1 in-' dicates a vehicle wind shield rising from 3 To the horizontal the cowl of a vehicle. top frame. member 3 are secured at spaced intervals suitable attaching plates 4 outwardly from which extend the fulcrum.

studs 5 on which'are'mountetl the ends of the respective arms 6 adapted to swing in an 'arcuate path from a substantially horizontal position to a substantially perpendicular one.. The free ends of the arms 6- are pivotally connected as at 7 bya channel bar 8 mounting the conventional form of rubber ueegee or wiping element 9, one end of t 0 frame extending preferably beyond its point of fulcrum connection with one arm 6. One of the plates 4, preferably that situated adjacent to-the, corner of the wind shield frame is formed on its lower' edge with a horizontal slot 9 in which is adapted to slidethe pin 10 carried by one end of a secondary channel bar llxwhich also mounts a conventional rubber squee 6 with which said ban-111s associated. "0n

the movement of 'the ,6 by the oper ation of a hereinafter described mechanism it will be observed that. the main wiping 1-30 shield while maintainedin a horizontal" 0-" element movesin an arcuate path acrossitlie sition and that the secondary wiping a e ment due to being pivotally secured at one end, swings in an arcuate path from a substantially horizontal to a vertical position. This movement of the two elements clears a relatively large area of the shield throu h which the operator may clearly view t e road.

To return the arms to their normal position, I prefer to employ a tension Spring 12 coiled at one end about the pin 5 extending from the plate slotted as at. 9 and the terminal end of said spring is adapted for reception within one of a number of recesses 13 depending on the desired tension to be imparted to the spring. The opposite end of the spring 12 is maintained in contact with the arm 6 by a clamp or element 14 provided with an eye 15 to which is adapted to be secured .one end of a flex ible operating cord 16 which passes through and operates within the guide opening 17 formed within the guide plate 18 secured to the wind shield frame. The opposite end of said flexible cord 16 is adapted for attachment by means of a clamp 18 to one of the vehicle pedals or levers 19 or to any other suitable element adapted for operating by the operator of the vehicle. If desirable, the cord may mount a hand elewent-20.

anemone Figures 2 and 3 illustrate an embodiment of the invention wherein the flexible cord element and spring 12 are eliminated and a hand crank 21 serves as a means for operating the wiper.

I claim 2-- 1. A wind shield cleaner including a pair of arms pivoted at corresponding ends to swing in arcuate paths, a horizontally disposed wind shield wi-per pivotally connecting the free ends of said arms, a second wind shield wiper pivotally mounted at one end adjacent to the pivot point of one of said arms and disposed with its opposite end connected to one end of said first mentioned wiper and means for. operating said arms.

windshield wipers pivotally connected together at one end, means for supporting their other ends means for simultaneously operating the same, one moving in an arcuate path from a substantially horizontal to a vertical position and the other in an arcuate path while maintained in a horizontal position.

In testimony whereof I have signed my name to this specification.
