This invention relates toan improved-construction of wiper for windshields designed to remove snow and ice therefrom andih'a's-f for its object to vconstruct a wiper fol-amig.'
PUTOS@ hol ing backing tube having a wiping 'strip the tube having a plurality of holes through which theice affecting liquid is suppliedto the stri to be deposited on the surface of the windshield by 'a movement of the wiper.
A further` object of the inventionis theA forming of this tubular member into a pluralit'yl of liquid holding compartments :from whic the strip is suppliedv with the liquid e purpose of obtaining a more even distribution of the liquid upon the strip and by the stri distributed upon the surface of the win I hield with which it comes in contact.
A still further'object of the invention is the provision of a pluralit of raduated holes thru the wall. of the wlper, ty ese holes decreasing. in' size toward the bottom of the tube to more nearly ualize the flow of the liquid to'thestrip o wiping. material.
ith these` and other objects in view,the invention consists of certain novel features of construction, as will 'be' more fully described, and particularly pointed'out inthe ap nded claims. g v
n the accompanying drawings: Figure 1 is al rspec'tive view illustrating my improved w1 er as mounte to be operated automatical y acrossa portion of the face of the windshield. l f i Fi re 2 is an enlarged sectional'elevation showing the tube as divided into a plu` rality offliquid holding compartments each communicatmg thru holes w1th the flexible wiping material. v
' igure 3 is a view of the back ofthe tube.
Figure 4'is a section on line 4-4 of Figu-re 2 thru lthe tube showing a'plurality of limel 5 5 of Figl I n Figure '5 is a sectlon on ure 2.
Figure 6 is a ure 2. 4 f h A igur'e is a rs'pective view ol t e arm at the int whelxi it is attached to the backing tu of -th'e'wipe'n y 4 It is found in practice particularly during the winter months that ice and snow acsection on line of Figcumulate on the surfaceof a windshield to such an extant that it cannot beremoved by actionof the ordi'nary'wiper and materiallyv interferes with the vision of the vehicle operator and myl present invention is designed g V g :forlthe-pur ose of dissolving or removing which is provided with a 'llqludf this ice an snow -from thev surface of a iwindshield and spreading upon the surface of flexible material fixed along its lengthy liquid and have arranged for this liquid to be deposited upon the flexible wiper which I preferably form. of absorbent material, the
same bein arranged to-be moved to cover a portion o the surface of the windshield to assist in preventing icy deposit and alsore! move any such deposit of snow and ice which may have formed thereon. It `is found that the forming of a tubular member of this 1 character with a plurality of separate compartments materially assists in the more complete distribution of the liquid along the contactin surface of the wiping material to r produce t e best results; and the following 1s a detailed description of the resent embodiment of my invention and s owing one Vmeans by which these advantageous results ma be accomplished.
ith reference to the drawings desig'- nates the backing tube which is of any suitable length, the interior ofxthe tube being provide with a separating wall 11 having a bottom portion 12 and another wall 13 having a bottom portion 14 providing upper,
. intermediate, and lower -compartments in` the tube.
This tubular member 10 is provided with bendableside lips 15 alo its rear edge between which a stri Yof a sorbent material 16 such as felt or t e like is positioned. and
these side walls are bent inward to g ip the same and so hold this material gr alnst the rear wall 17 of `this backing mem r. The-, Crear wall of the upper com artment 18 is provided with holes 19 whic communicate -vwith the corresponding portion of the felt wiper. The intermedlate compartment 20 1S wit its portion of the felt and the lower rovided with holes 21 communicating` ioo compartment 22 is provided with holes 23 communicating `with its ortion'of the f elt wiper. The holes 19 in t e 'up ment being dplleferably larger-t the interme r compartd those te compartment'and holes 28/ in the lower compartment bei slightly smaller than those in the interm 'ate com,- partment, whereby there is a little greater proportion of the liquid ih the upper portion is permitted to flow to the wiping material as this liquid is designed to work downwardly by its gravity and also upward by capillary attraction, and these two o posltel acting influences serve to provi e a fair y even distribution along the length of the wiping material .particularly as `the wiper is oscillated back and forth the liquid is caused to run back and forth along the walls of the different compartments and splash thru the openings especially when rapidly operated.
A cork or closure member 24 is placed in the upper end of the tube to close all of these tubes simultaneously so that theywill not communicate with each other.
The whole wiping device is suspended from thc operating arm 25 which is connected at its lower end as at 26 to the fin 27 on the back of the wiper tube and isV connected at its upper end as at 28 to the usual automatically operating device 29 which imparts movement thereto.
My improved wiper is very simple and practical in construction and effective in its operation and by its use the cleaning liquid is evenly distributed along the length -of the wiping material toremove the snow and ice from that portion of the windshield with which it comes in contact and when any portion of the felt becomes dry and fails to 'effectively perform its cleaning operation this surface serves as a signal to the operator that the whole ldevice needs refilling.
The. foregoing description is directed solel towards the construction ill but desire it to be understood that I reserve the privilege of resortin to all the mechanical changes to which t e device is susceptible, the invention being defined and limitedY only claims.
I claim by the terms of the appended 1. A wiper for wind shields comprising a the windshield, a liquid holding tube fixed along said stri of a length substantially the lengthA of t e strip, said tube having a set of graduated holes along its length decreasing in size toward the bottom thereof and communicating with and su plying said absorbent material with a liquid wiping strip of absorbent material to I 1 1 1 from the tube-to be., deposited upon thev ments, a wiperstrip secured to said tube, l
each compartment having. a hole thru which liquid from said compartments is supplied to different portions of said stri to be applied to the surface of the winds 'eld along the length of the wiper. l
In testimon whereof I aiix my signature.
