Application filed July 27, 1908. Serial No. 445,458.
To all "whom "it may concern:
Be it known that l, J OHN- EDMiAN, a citizen of the United States, residing at Minne apolis, in the county .of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Devices for I Cleaning the Outside of Windows; and I do herebydeclare the following to be a full,
' clear, and exact description of the invention,
such as will enable others skilled in the art to which it appertains to make and use the same;
My present invention has for its objectto provijle a simple and el'licient devlce for clean'ng the outside of windows, by manipulatidn ofapart. located at the inner side of the window, and to the above'end the invention consists. of the novel devices and combination of devices hereinafter described andfdenned in the claims. The said invent-ion is s ially designed. as an improvement on the eviceset forth and claimed broadly in application for Letters Patent of United States No. 441,938, filed of date July 6, 1908, by myself,-John Edmund and one Alfred T. '-Lidh0lm, and entitled. devices for cleaningoutside of windows. f
The present. invention .isidirected partice ularly to improved means for causing the -s'cra er blade to tightly press against the win ow pane under its operative movement, and to be released from the window pane and hence freely moved while making its return or' idle movement.
, In the aeeompanying drawings like characters indicate like parts throughout the several views' I Referring to the drawings: Figure 1 is a view elevation, looking'at the outer side of a window, such, for instance, as the front window of an engineers'cab or of amotormans' vestibule, and showing my improved scraper applied thereto. Fig. 2 1s avertical ,section taken on the line w m of Fig. 1; and. Fig. 3 is a horizontal section taken on the line w s of Fig. 2, some parts beingbroken of the window pane 2. To the opposite ends thus also compensated for.
. guide chah'nelsf of the bar 3 guide shoes 5 are rlgidly secured-and are arranged to slide vertically in parallel channel shaped guides 6. As shown,
said guide strips 6 are adjustably secured by slot and screw connections 6 to brackets 6", which latter are directly secured to the sides of the sash 1. By lateral adjustments of the guide strips 6 toward and from fliesash 1, the flexible blade 4 may be arranged to engage the window pane 2 under outward pressure, and wear o f the said blade may be These channel shaped guides 6 areprovided with intermediate ribs 7 that extend considerably less than fronitop to bottomof the respeptiye Byreference to Fig. 2 will be noted that the upper and lower ends of the shoes 5 are reversely beveled. The importance of this will presently appear. v
Suitable y elding means, such as oner-or "more springs, are employed to'impart the idle or return movements to the bar 3 and the scraper blade 4:; and this inoperative movement is preferably'the upward'moi'enient of the said parts. The yielding device shown in the. drawings is a "filler 8, journaled in suitable bearings 9 on the upper portion of the sash and subject to a torsional spring which tends to move said roller in the direction of the arrow marked adjacent. thereto, in Fig. 9. This roller 8 is connected by cords or small cables ll. to the end portions of the scraper carrying bar 3, Small operating cords or cables 12 are attached at their upper ends. to the ends under guide sheaies 13 on the lo\ ver--portion of the sash 1 and are extended around g'uidesheaves mounted in a bracket,- 15 in the lower portion of the sash and1 -both are attached to a common'hand piece 16*thatis located at the inner side of the sash.
By reference to. Fig. 2 it will be noted when in the. normal position of the parts, shown in Fig. 2,-the scraper blade strikes the overlying uppenshoulder of the sash.
and acts as a fulcrum over which the-bar 13 is swung outward under the upper pull of the torsion springlO, untilthe lower portion of the shoes5 strike the outer flanges of the guide channels 6. It will also be noted that in this position the bar 3 is outward of -a straight line drawn from a guide13 to the inner surface of one end of the roller 8.
- of said bar'3, and these cords 12 are passed Hence, under downward pull on the cords 12 the bar 3 will be caused to swing slightly toward the window pane 2, until the beveled lower ends of the shoes 5 aline with the innermost of the two channels of the guide strips 64 When the shoes are caused to travel through the said innermost channels,
' shoes 5 outward, so that when bar-3 andthe scraperblade tare given their upward or idle movement under the force of the torf sional spring 10, the said. shoes will pass upward through the outer channels of the guides 6 and the scrape): blade will be carried upward out of contact with the window pane. In this way the upward or idle movement of the scraper blade is insured, even when a yielding device of no great strength is employed.
Inactual practice the efliciency of the device has been demonstrated.
I claim:
1. The combination with a window and a pair of laterally spaced vertical guides, secured adjacentto the sides thereof, each of which guides has inner andouter channels that run together at upper and lower extremities, of a 'bar having a scraper blade for action on the window pane and arranged to engage with the sash, at the limit of its upper movement, shoes rigidly securedto the ends of said her and having reversely,
beveled upper and lower ends, a deviceoperating to yieldinglyhold said bar in ts;
uppermost position, and a downwardly e;- tended operating connection from the said bar, whereby the said shoes will travel.
through the innerchannels of said guides when moved downward and will travel through the outer channels of said guides when-moved upward. I
2. The combination with a window and a pair of laterally spaced vertical guides secured adjacent to the sides thereof, of a' guidevbar'having a scraper blade for action on the window pane, the said vertical guides being adjustable toward and from the window pans to vary the engagement of said scraper blade with the pane, and means 'for moving said 'blade equipped bar from the inner side of said window tiallyas described.
3. The combination with a window and'a pair of laterally'spaced vertical guides secured adjacent to the sides thereof, each of "said guides havi'ng inner and outer channels that run together at their upper and lower extremities, of a bar having ascraper blade for action on the window pane, shoes applied to the ends of said bar and having reversely beveled upper and lower ends, a device-operating to yieldingly hold said bar in one extreme position, and an operating connection from said bar extending to the inner side of the window, substantially as described.
' In testimony whereof I athx my signature in presence of two witnesses.
' I J OHN. EDMAN.
