WINDSHIELD CLENER.

Application filed April Thepresent invention relates to cleaning devices for use in cleaning glass surfaces, and more specilically to an improved cleaner for use in removing dust and the like from the windshields of motor vehicles.

The primary object of the invention is to provide a novel and improved type of heated windshield cleaner.

A further object of the invention is to provide a novel type of windshield cleaner embodying means whereby the device may be heated for the eiective removal of snow and ice from the windshield when driving in inclement weather.

further object of the invention is to provide a novel type and improved type of electrically heated Windshield cleaner which may be readily -attached to the usual arm of cleaner actuating -mechanisms as now in common use for movement of the cleaner across the surface to be cleaned.

A still further object ofthe invention is to provide an improved electrically heated windshield cleaner which will be of extremely light yet durable construction and one wherein the heating medium or element is readily removable from its carrier portion.

A still further object of the invention is to provide an improved electrically heated windshield cleaner embodying a novel arrangement whereby the heat is eEectively directed toward the glass over which the cleaner is moving without any likelihood of the heat becoming too great and resulting in possible breaking of the glass.

@ther objects and advantages of the invention will be 'apparent during the course of the following detailed description, taken in connection with the accompanying drawing, y.

nate `corresponding parts thruout the several views, the improved cleaner is shown as embodying a 'loackor frame A provided with spaced wiping elements B, and a removable heating medium C.

Referring first to the construction of the back or `frame A, the sam'evis preferably formed from sheet m'etal of a suitable grade Jformed to provide arcuate outwardly bulged longitudinal side walls 10 forming a substantially tubular housing extending thruout the length of the frame. The inner or free edges of the walls 10 are bent to provide parallel longitudinal attaching flanges 11 which also extend thruout the length of the back. These longitudinal flanges 11 are suitably spaced lfrom one another for forming the longitudinally extending opening as at 12, and it is preferred that the flanges have a normal tendency to spring toward one another so as to afford a proper gripping action upon the heating medium C. The metal at the outer or connecting ends of the side walls 10 is bulged outwardly for forming a ch-annel-like rib 14 which also extends thruout the lengthy of the back A, and this rib aside. from serving a function to be subsequently explained, further acts as a reinforcing means for the elongated frame.

Thusit will be seen that )the body portion ot' the back or frame A may be easily formed from a rectangular shaped piece o sheet material for formation of the substantially tubular way 15 being open at its inner side and closed at its outer side by the longitudinally extending channel-like rib 14,-. rlihe inner end of the open way 15 is preferably closed by means of a flat cap plate 16 of a conguration conforming to the end formation of the back, and which cap plate is provided at its ,inner edge with inwardly extending apertured ears 17 which are adapted to be secured to the flanges 11 as by means of suitable rivets 18` .preferably having counter-sunk heads at their connections y.

with the flanges 11. The cap plate 16 aside from providing a closure for the inner end oi the way 15 also serves as a positive spacing means for the inner ends of thetlanges A U-shaped attaching clip 18 is preferably riveted to the walls 10 at their juncture with the rib 14, and preferably at the longitudinal center of' the 'frame as illustrated in Figure 1. This U-shaped clip 18 is aperturedJas at 19 for receiving a suitable wing nut 2O whereby the arms of the clip may be vrigidly clamped about an actuating arm 21 of a suitable cleaner operating mechanism. The arm 21-may have movement imparted thereto in any suitable manner for movement of the cleaner across the windshield' eitherin an arcuate path or for movement of the cleaner transversely across the windshield. The wiping elements B, and one of whic is intended to be carried by each of the spaced flanges 11, eachiembodies a U-shapedv carrier portion 23 adapted to be clamped about one longitudinalv edge of suitable wiper blades 24 formed of any suitable material such as rubber or cloth. The wiping elements B are secured longitudinally at the outer face of each of the flanges 11 as by means of suitable bolts and nuts 25, and as will be observed, the wiping elements are i adapted to be readily removablev from the frame A, embodies. an elongated core 28 of insulating material such as porcelain or the like, and which core is of tubular formation and provided with a longitudinally extending slot 29 which extends thruout the entire length of the core. The outer end of the core 28 is externally enlarged as 'at 30 for forming suitable bosses which will engage the outer end of the frame A for limiting inward movement of the core within the tubular wa 15. Asr will be observed Iin Figure 1, t e core 28 is of less length than the frame A .and thus when the bosses 30 v engage the outer end of the frame, the inner `in Figure 4. The core 28 is intended to serve as a suitable carrier for a heating element 35 preferably in the form of a resistance wire being crimped intermediate its ends as at 36. This wire heating element 35 extends thruout the length of the core 28 and is attached at its inner end to a suitable bolt 37 mounted yin suitable, insulating washers 38, and at its outer end attached to a suitable bolt 39 mounted in suitable insulating washers 40. Thesebolts 37 and 39 serve as terminal binding posts for electrical conductors 41 and 42 respectively, and which conductors may pass thru a suitable switch to a source of electrical energy such as the battery of the vehicle.

The conductor 42 is connected to the bolt 39 at the outer end of the core, while the conductor l.t1-extends lon itudinally of and externally' of the core or attachment to the bolt 37 at the inner end of the core. rlhusfit will be seen that when the heater is inserted into the frame A, that the channellike ribv 14 provides a space for accommodating that portion of the conductor 41 whichfextends longitudinally of and externally of thecore 28. When the heater is inserted in the frame A with the conductor 41 in the channel rib 14 and the bosses 30 engaging the outer end of the frame, the yieldable walls 10 of the frame will grip the core 28 sulliciently for preventing rotation of the core or movement of the core longitudinally out of the frame.

The object in socrimping the resistance wire 35 at the longitudinal center of the core 28 is to provide more heating area at the center of the cleaner for effectively cleaning snow and ice from the windshield without excessive heating of the conductors 41 and 42 at their connections with the terminal bolts 37 and 39. As will be observedzin Figures 1 and 4, the flanges 11 and wiper blades 24 will cause the heat from the wire 35 to be directed thru the opening 12 and thus spaces the wire a sulliacient distance from the Windshield as to eliminate possibility of the glass being heated to a degree'whereby the glass would be apt to crack. c

As will be seen, when the cleaner is moved across the windshield by means of the arm 21, that heat from the element 35 will serve to effectively remove snow and ice from the windshield glass and thus allow the operator to have a clear vision thru the windshield.

Byoso-having the heating medium C so' ing medium readi ly removable from the frame for the ready making of repairs, and which supporting frame is of such novel construction asto allow for the current conducting wires to be readily attached at opposite ends of the heating medium and not,

materially affected by the heat generated by the heating element. y
