PETER F. DALY, OF CHICAGO, ILLINOIS.

WINDOW-CLEANING APPARATUS. 9

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed September 23, 1909. Serial No. 519,274.

To all whom it may concern: '13s it known that I, PETER F. DALY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in VVindow-Cleaning Apparatus, of which the following is a specification.

This invention relates to devices or apparatus adapted for cleaning windows and I particularly applicable for-use on the front windows of street cars, railway cars, and motor vehicles or other. conveyances. Its objects are to'provide a simple and efficient means for removing the rain, vapor or moisture=,-from the-outer side of the window, together: withf suitable operative mechanism whereby the cleaning device may be 0perated by the driver or motorman without leaving his position in the car or other vehicle.

A preferred form of my invention, showing the mechanism for accomplishing these ob ects, is shown in the accompanying drawin s, in which-f igure l'is l side view of one end of a street car equipped with my window clean ing device,'p'arts being broken away to show the interiorconstruction; Fig. 2 is a front view of the car shown in Fig. 1; Fig. 3 is an enlarged sectional detail showing the window cleaner and return mechanism; Fig. 4 is a' detail'of one of the clips for holding thereturn-spring tube; Fig. 5 is a detail showing the adjustable 'cap for the foot ,plung'em'Fign dis a sectional plan view t aikefilonlline'fis ii 'of Fig. 3; and Fig. 7 is a front View of the parts shown in Fig. 6.

As indicated in these drawings, 8 represents a street car of any ordinary construction, although it will be understood that my improved window cleaner may also be applied to windows of other vehicles, or in fact to windows of any kind where it may be'adaptdto be used. The sash of the front window of the car, to which my deviceis applied, is indicated at 9, and the pane thereof, at 10. Along the posts or frame forming the front of the car, I provide guides 11-1-1, preferablyof rectangular cross-section and open at one side, as"

shown most plainly in Fig. 6. These guides are provided w1th lugs 12, having screws .13lw ich' engage with posts or other suitable part: of the car frame. Slides or carriages 14 engage with the guides 11 and support ber-s15 with friction shoes 16, these shoes be ing held against the iner sides of the guides 11 by means of springs 17, as shown in Figs. 3 and 6.

The squilgce or cleaning device proper 18 comprises a long bar of angular cross-section, as indicated in Fig. 3, the main portion of which is provided with trunnions or gudgeons 1!) which engage with the blocks 15 of the slides or carriages 14, while the inwardly extending portion is provided with a wiper 20 of rubber or other suitable material adapted for cleaning a window, this wiper being held in position in any suitable manner, asby means of the screws 21 which clamp it within the groove in the edge of the bar. Lugs or pro ections 22 extend 1nwardly from this bar, acent to the trunnions 19 and engage with clamps or clips 23which are secured to the operating ropes 21 and 25. One set of these ropes or cords is for drawing the device down, and the other for returning it to normal position; of course, continuous ropes may be used, if so desired. The ropes or cords 24 pass up and over guide rollers or pulleys 26 and 27 in the upper end of the guides 11 and then extend inwardly through the front of the car where they are secured to the ends of tension springsQS preferably arranged within the tubes 29, these tubes being secured in the top of the car by means of clamps 30. Adjustment'of the springs 29 is provided by having the ends of the springs secured to slidable nuts or threaded members 31 which engage with screws 32 passing through caps 33 in the ends of the tubes 29, these screws being held in adjusted position by means of nuts 34.

The ropes 25 extend downwardly and engage with winding drums or sheaves 35 secured on'a cross shaft 36 which is held by means of hangers 37- from the bottom of the car 8. The shaft 36 is provided with a pinion 38 which engages with a segmental rack 39 on'the end of a lever 40 pivoted at 4:1 to suitable hangers or supports 42 from the bottom of the car. The opposite end of the lever 40 is slotted to receive a roller 43 in the end of afoot plunger 44 which extends upwardly through a bearing 45 in the bottom-of the car, and is provided at its top with an adjustable cap 46, this cap being held in adjusted position by meansof a lock nut 47, as indicatedpaatieulaply; in Fig. 5. At the upper end of the bearing.

45 is secured a I'UdQbQI washer or buffer 48 which is engaged by thelock nut 47' when the plunger 44 is pressed downwardly to its spring-pressed shoes 16 will cause a sufficient friction on the sides of the-guides '11 so that.

lowermost position. A spring 49 is secured tot-he inner end of-the lever 40 and -tolthebottomof'the car, andis adapted to return the lever' and plunger to as indicated in Fig. 1;

The particular" form of my invention shown in the drawings will be readil under stood from the above description. ation, the e motormanor driver presses his footoiftrthe cap of the plunger 44, w-hiehcauses the inner endof-the .lever 40 to be swung -downwardly, thereby; turning the segmental rack 39,-rwhich rotates the pinion 38,"thereby causing the shaft 36 and sheaves or drums 35 -to revolve: and wind up the. cords or 'cables 25; On-account of the upperends of these cables being securedto" the.

barof'the squilgee atsome distance from thecenters of the trunnions 19, they cause-the bar to be swung toward the window pane, thereby causingthe wiper 20'rto .be drawn forcibly against and down across the surface of' the pane. -This will efiectivelyremove'any moisture, dirt-or- :dustfrom; the

front of the: pane, leaving the glass clean so'that' the driver or motor'man'mayreadily;

see out of thecar. It willlbe noted that the the forward orswinging movement-oftfhe squil'gee will be effected before the carria es or guides 15. start -to move downwarly, thereby insuring the close engagement of the wiper '20 'with--the'- window pane. When the plunger 44 has beenz-movedtothe end of its stroke, the'operator removes his foot.

from the cap 46, thereby releasing,- the plungerand allowing the spring 49 to return the plunger and connected parts to. normal position. Simultaneously, the
