WINDSHIELD CLEANER.

Application filed May 3,

. The main object of my invention is to produce a simple and practical wind-shield cleaner which will keep thepart of the windshield within its scope free and clear from sleet and snow.

Another object of my invention is to provide a construction which can be readily attached to existing wind-shield wiping mechanisms. I Y

Another object is to provide a means for wiping as well asdrying the glass of the wind-shield.

Another object is to provide a construction-which is durable and yet is easily repaired.

Another object is to provide a construction which will apply heat to the glass without injury to the wiper.

Another object is to provide a heating cleaner which is electrically and thermally efiicient.

I accomplish this object by constructing a holder in whole or in part of insulating material which may preferably be molded and providing it with one or more channels adjacent the wind-shield and mounting in these channels electrical heating'members spaced away from the wiper. I

By means of my particular construction hereinafter set forth in detail, the wiping member proper is protected from the'heat.

produced by the heating member and the heating member is so placed that it is protected in turn from the wind and transmits substantially the entire heat to the face of the windshield.

Referring. tothe drawings Fig. 1 shows a perspective-view of the wiper attachedto a motor car.

erably has high insulation properties both as to heat and as to electricity and may be moulded. This casing or body is of inverted U-shaped section as shown in Figs. 3, 4 and 5. It carries at its upper end the extension rib ll-into which may be moulded the tube 12 carrying the set screws 13 and 14 which may engage the rod 15 which may be actuated by the usual wiper mechanism (not shown).

The metallic lower end plate 16 has pins 17, moulded in the body 10. The threaded bushings 18 carrying the set screws 19 for engaging the metallic holder 20 of the wiper 21 may also be moulded into the body 10. This body or casing 10 also carries the sockets'22 and 23 which serve as terminals for both the heating units 24 and 25 and the 180, thus securing the heating coils 24 and I 25 and heat insulatingthem in all directions save towards the wind-shield. Instead of the heating coils 24 and 25 a straight wires such as 30 in Fig. 7, may be employed.

In assembly a straight portion of each heating coil of correct diameter and resist- -ance issintroduced into its channel in the member 21 is protected from the effects of the heating members 24 and 25 and as soft rubber is the preferable material of said wiping. member, this is an important fea- It will be seen that a'channel is provided on either side of the wiping member to allow the melted ice, sleet, or snow, to 'run out of the bottom of the casing. Also that the heating members are so retained 'and positioned so that a large percentage of their heat is applied substantially di rectly to the wind-shield with little loss of heat to the open air.

It should be understood that while I have described one embodiment of my invention, I do not wish to limit myself except to the extent of the claims hereinafter set forth.

I claim:

1. A wind-shield cleaner comprising an insulating body having spaced apart flanges, beaten members mounted in said flanges adjacent the outer surfaces thereof and a wiper element mounted in said body be tween said flanges and thermally and electrically insulated from said heater elements.

2. A wind-shield cleaner comprising a body having spaced apart flanges, heater elements mounted in said flanges. and pro vided at one end of said body with means for the attachment of circuit wires and having a conducting and plate connecting said elements on the other end of said body and a flexible wiper element carried b said body between said flanges and space apart from said heater elements.

3, A wind-shield cleaner comprising a body member having an insulating flange with an open groove in its outer face, a

heater element mounted in said groove and exposed toward the wind-shield and a flexible wiper member secured to said body and spaced apart a substantial distance from that portion of the flange which carries the heater element, said flange serving to prevent radiation of heat from said heater element in substantially all directions except toward the windshield.

4. A wind-shield cleaner comprising an insulating body having a flange with a longitudinal groove in its outer face, a heater element removably mounted in said groove and exposed at the outer face there of, and a flexible wiper member having one edge detachably secured to said body and the other edge spaced away from said heater element and adapted to co-act with the wind-shield glass when in use.

5.A wind-shield cleaner comprising a body having means for securing it to an operating mechanism, said body having
