,ofanautomobiley, I In orderto. reverse the motor 30 when:

Fig. 2 is an enlarged sectional side elevae ever theearriage nears the end of its trav l tion of the same on-the line 2.-2'.of.F ig-. 1; in either, direction, use is made of a switch 55 3 isja seetional plan viewofthewip- -lever,40--fulcrumed at 41 and adapted to W engage alternately contacts 42, 43, and44, i5

- shown in I pressed on arranged in the motor circuit, as plainly Figs. 5 and 6; The switch lever 40 is provided with two inclines 50 and 51 engaged by aball 52 held in a cage 53 and by a spring 54 mOunted in the. 53 is attachedto a Theend 56 of the switch rod 55 is adapted I gages the spring use is made of a stopping and startingto move in engagement with a spring arm 58 held ononeside of the-frame 12, and the end-57 of the said switch rod 55 is adapted to'engage'asimilar spring arm 59 attached to the oher'side of theframe 12. When the carriage'20 travels, say from the left to the right, and nears the end of its travel in this direction then'thee'nd '57 of the switch rod 55"eng'ages the spring arm 59 whereby the rodf 55is shifted from the right to the left and in domg so the ball; 52 moves out of en the incline and into enwith the stopping and starting switch 60 in open position and with the cleaning device gagement with gagement with the incline 51 thus imparting a rocking motion to the switch lever 40 to disengage the same from the contacts 42, 43

and to engage the same with the contacts 44:, I

.45 thus reversing the motor 30. .The carriage 20: is now caused to travel from the right to the left and when the carriage nearsthe end of ts'travel in this direction then the end 56 of'the shifting rod en- 2 arm 58 whereby the shifting rod '55 is moved from the left to the right and the ball 52 moves out of engagement with theincline' 51 and moves into engagement with the incline 50 thus rocking the l ever 40 to disengage the same from the contacts 44, 4:5 and engage the contacts 42, 4:3 thu sfa gain reversing the motor. The carriage 20' now I tion that is, from the left to the right, and

theabove described operation is repeated aslong as the motor 30 is running.

In order to stop and start the motor 30 switch 60 see Fig; 6.)' arranged in one of the line wires of the motor, the switch having a three-arm lever 61 of which one arm "1s adapted-to engage and disengage insulated contacts 62 arranged in theline wire ;,t0 close the switch or open the same. other arms of the lever 61 are connect-ed with push buttons 63,6 1 mounted to slide in a plate 65 arranged on the instrument board 66 of the vehicle so that the'push buttons 63'and 64 are within convenient'reach of the'driver or operator to start or stop the motor 30 on the operator pressing the corresponding button.

.The pinion 35 is located near the left hand end of the casing 26, and order to properly balance the carriage to insure easy running thereof use is made of art-idler pintravels in the opposite dir'ec- 1011 70 in mesh with the-rack 36 and mount.-

ed on a shaft 71 journaled in the casing 26 near the right hand end thereof, as plainly shown in Fig.

In order to insure proper contact of the wipers 21 and 22 with the corresponding surfaces of the glass plate 10, use is made of springs 80 and 81 attached to the carriage 20 and provided at their lower ends with set the outer andinner surfaces of the glass plate 10. The wipers '21 and 22 may be of any 'approyed construction, preferably of the squeegee type having rubber wiping members (see Fig. 3) the free ends of which bear tightly against the faces of the', glass plate 10. Oppositesides of the wipers 21 and 22 are pressed on byspring arms 85,- 86

to reinforce the wipers against the strain incident to their wiping action when moved across the surfaces of the glass plate 10.

Normally the cleaning device is inactive carriage nears the end of its travel in either direction the switch rod 55 engages the correspondmg spring arm 58 or 59 and is thereby shifted, andthe reversing switch now reverses the motor 30 and the carriage 20 travels in an opposite direction. The carr1age '2O travels alternately in opposite di-- rections as long as the motor 30 is running and in doing so the wiping elements 21 and 22 wipeand clean both surfaces of the glass plate 10 of I all extraneous matter. After this has been done, the operator presses the button 64- and thus 'opensthe stopping and starting switch and the supply of electric energy to the motor now ceases,' the motor stops and the carnage comes'to a standstill.

Usually the operator presses the button 64 at the time the carriage is in position near one end .of the wind shield so that'the cleaning device does not obstruct the vision of the operator.

It is understood that the source of electricalflenergy for the electric motor is derived from the storage battery now generally used on automobiles and similar vehicles, but I do not limit myself to such a source of electrical energy as in many applications of the cleaning devlce other sources .of power will have-to be. used. his further understood It wi 1 be noticed that althou hthe cleaning device is shown applied to't e wind shield of an automobile I do not restrict myself to such use as the cleaning device maybe applied tovarious articles, the surfaces of which require to be .kept clean "of rain, 'sle et,isnow', dust and other extraneous matter.

The cleaning device shown and; described is very simple and durable in construction, canbe readily applied to the article to be cleaned without materially alterin the con-- struction thereof, and so appfie that the cleaning device forms a permanent fixture of the rticle. I

that the cleaning device attached to a wind shield or other article does not interfere with the manufacture. closing or other pur thereof for opening,
