haveinvented certain. new :and useful Ime* piovements in Wi-ndshield" Cleaners', of which the following is a specification.'-. Q- This invention relates -to windshield windshield .clean-en `Whicli=j may be -motor driven' or driven inany jother s ultable mangner 1n which v a .pan-of cleaner elements are 2c employed, thej cleaner 'elements 'being preterably arranged-adjacent -the'sides of. the

` -windshield' The cleaner elementsare. connected in any suitable mannerto .an actuating 'member whereby the cleaner elements .are os cilla ted. A single voperating member pis connected-'tc the' actuating member in any vsuitable manner to drive said actuating member whereby the-cleaner elementsjmay be oscillated.. f Y

' Infthe forms. of.- the invention' herein disclosed, wehavc employed a .motor 'operated device; of substantially the construction shown in thecopending application of Wilv lliam MQ Folberth, fiiled' January`25, 1919, 'Serial No. 273,143.

Referring to Figures 1 to 1 of the draw I ings, the reference numeral 1 designates a Windshield mounted in a suitablct'ranie 2. A bracket 3 is arranged on the top oft' the Windshield frame in .any suitable manner, this bracket being adapted to receive and support a cylinder 4 which forms the operatingA mechanism of the windshield A pair of pistons 5 are arranged in this cylinder, the pistons being adapted to be operated by mea-ns of pressure or Suction, as desired. The actuating means employed in the application of `Willia1n M. lFolberth, referred to, may be employed t o operate the pistons, the cylinder being connected to the intake manifold by means oi a pipe 6. As the manner in which the pistons are operated and the valve mechanism by means of which alternate ends of the cylinder are connected to the pipe 6 forms no part of the present invention, a det-ail description thereof is deemed unnecessary. rlhe istons 5 are connected by means of a web having rack teeth 8, arranged thereon. A gear 9 meshing with the rack teeh i s shown, the cylinder is provided with an "similar view showing the .connection between the motorshaft and the "actuatingl member,

opening 11, arranged in the top, and the Above in 1 the 'of arod 14 :is arranged within tending substantially the entire width ofVv the windshield. vAs shown, the actuating 'member is provided with rack teeth 15, adapted to mesh with the teeth of gear wheel 9. Arranged adjacent the sides of the windshield and spabed fromeach other are a pair of supports 16 for the cleaner' elements As the construction of each of outer member is provided with alined open*- ings for the reception of` a shaft 20, the f Shaft having a'rod or arm 21, secured thereto in any suitable manner, as by setscrew 22. The cleaner element 23 is carried 'by this arm. The opposite end of the shaft is provided with a gear wheel 24:, adapted to.

mesh with'rack teeth 25 arranged on the .actuating member. As shown, the inner arm of the bracket 18 is extended as at 26,

and is depressed as at .27, toform a g'uideway for the end of the actuating member.

The extreme end of the arm is extended upwardly, as at 28, to engage the yend of the shaft l2,0 and prevent longitudinal Inovement of the shaft. y

` lnv the form of the invention shown in Figures 5 to 7 of the drawings, the actuating member lin the form of a flexible chain 29 1s `sides thereof, the central portion o employed. The gear 9 is provided with two sets of gear teeth 30, arranged at op rosile t e ear being reduced, as at 31. The cha-in 1s adapted to surround this portion of the gear, and may' frictionally engage it as shown, or the reduced-portionmay be provided with sprocket teeth (not shown) to furnish a more positive drive. As shown, a

pairof racks V8'are provided, meshing with -the two sets of gear teeth 30.

The chain 29 passes over sprocket wheels 31 arranged on the shafts 20 ofthe cleaner elements, the sprocket wheels being providedwith suitable sprocket teeth 32.

y Referring to Figures 8 and 9 of the draw-4 mgs, the cylinder 4 is provided with the usual pair of spaced pistons 5', connected by a rod 33. The rod extends through the cyl-k lnder heads in each direction, being pro-- vided with suitable packing, as indicated at 34. Ad]acent the ends of the rod, sets of element.

rack teeth 35 lare'provded, adapted to mesh with a gear 36 on the shaft of the cleaner In the form-of the invention shownin Flgures 10 to 12 of the drawings, the construction of the cylinder and pistons is the same as in Figures 1 to 7. A. crank arm 37 is arranged on the actuating shaft, the

crank arm being rigidly secured to the shafty and being oscilla-ted by the oscillation of the shaft. A pair of links 38 are connected 7o to this arm and the ends of the links are secured to cranks 39, carried by the cleaner shaft 20.

In the operation of the form shown in Figures 1 to 4 ot the drawings, the pistons 5 are reciprocated in the cylinder by suitable means, causing the motor shaft 10 to be oscillated by engagement of the 'gear wheel 9 and the rackV teeth 8. This oscillation is transmitted to the actuating member 111 bythe rack teeth 15 and the cleaner elements 23 are'oscillated in an arc of a circle -by means of gear wheels 24 and rack teeth 25.

lin the` form of the invention shown in` Figures 5 to 7 of the drawings, the engagement of the chain 29 with the gear wheel 9 causes the chain to be oscillated when the motor shaft 10 is oscillated, and this oscillation is transmitted to shafts 20 by means of sprocket wheels 31, engaging the chains 29.

- In the form of the invention shown in Figures 8 and 9 of the drawings, reciprocation of the pistons in the cylinder causes the sets of rack teeth 35 to be reciprooated, oscillating the gears- 36y and thus oscillating the cleaner elements. The operation of the form of the invention shown in Figures 10 to 12 of the drawings lis substantially the same las in the other views. use of the ating mem erand the cleaner shaft is elimi- However, the gear connection between the actunated, and these membersare connected by means of cranks 39, whereby the cleaner eley ments are o'scillated when the main shaft 410` is oscillated.

1t will be apparent 'that by means of the present invention, a air of cleaner elements arranged on a winds ield in spaced relation.

to each other may be oscillated .from Sa single source of power. Asstated, the motor herein disclosed 'by means of which the power is furnished forms no part of the invention except in the combinatlon claimed,

land other meansfor oscillatingthe actuatelements may be employed.

ing member Iand thus oscillating the cleaner It is to be understood .that the forms of our invention herewith shown and described are to -be taken as., preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to `without departing from the spirit of the invention or the scope of the subjoined claims.
