Be it known that I, Josurrr BARON a citizenof the United States; residing at Rocka- 7 way Beach, in the county of Queens and State ofNew York, have invented certain new and useful: Improvements in Window-Cleaning Meehi nes; ofwhich the following is a specificctio'n; This invention relatesto window cleanmg machines, and more particularly to that type of machines by which the outside sur- "lfaceof window panes are cleaned or washed 1 by the operator standing inside of the buildto provide a machine which will-use a mini.

One of the main objects of the invention is to provide a simple'and efli'cient machine of the Character stated. A further object is mum of water or other washing liquid during its 0 eration. A still further object is. to p'rovi e a machine having a squeegee or pane engaging member in combinationwith a. spraying device, these two members be in'g so related that the elndow is washed 25 during one operation of the squeegee, and dried during the second operation of the squeegee. Further objects will appear from the following detailed description.

In the drawings Figure 1 is a side View of the invention as 'Fi sis a section on line e 2 of Fig. 1, -;Fig. 3 is a section on line H of Fig. 1, inig; ,4 is a. section on line 4-4 of Fig. 1,

jFig. 5 is a. section on line 55 of Fig. 1,-

and v 1 Figs." 6 andjl ,are details. Broadly stated,- my machine consists of a.

, vertically slidable squeegee, a spraying deits inner end with lateral arms 2 for bracing and steedying urposes, and near its outer end with simi or arms 3. 'A suitable tower is mounted upon this base intermediate its ends; This tower is of U-shepe having an inner leg 1. and an outer leg 5, both.

fixedly secured to' the base. The outer leg is of channel construction and slidably receives the outer sun (i of an'adjusteble U- head 7, the inner arm 7 of which is reduced as at 7 and fits into-a socket-1n the upper Specification of Letters latent. Application and June 10, 1910. Serial x0, mama.

end of lei; of the tower. The outer arm 5 of the U: eeil is provided with a, U-clasp 8 fixedly securzd thereto and embracing the outer leg 5 oi the tower. A binding screw 9 1s threuded't irough the bar 10 of the clasp 8 so as to eng age the leg 5 of the tower so as to secure the head 7 in vertical adjustment. A grooved ,p ulleyll is rotatn blv mounted in the in'ner eg of head I in vertical-Mine ment with a. similar pulley 12- monn'ted' in thelower one of le 4. of the tower. Pulley 12 18 secured on a ongitudinel shaft 13 rotatably mounted in standards 14., and the upright 15 f1 n'med at the inner end of the base. Above shaft 13 a stub shaft 16 is rotntably mounted near. the upper end of upright 15 and carries a drive ulley 17 keyed on its inner 11nd, and a. or handle 18 secured on its outer end. 1 Drive pulley 17 is in vertical e1 nement with a. grooved pulley 19 secured o1 shaft 13 and is operetively connected the reto by a cord 20.

This eonstruction will be clear from Fig. 6 of the drawings.

The wheel 23 carries an. eccentric pin 28' which is com ccted by a link 29 to the lower end of the vertical. arm of an angle rod 30.v The lower enl of this urm is provided with a short sockel 31 secured thereon by a; bind: ing screw 32, the lower end of which is $101;- ted to receive the upper end of link 29. The horizontal arin of rod 30 is secured through the eye 33 of a socket 34 secured on the upper end of a piston rod 35. On the lower end of piston rod 35 is secured a piston 36 operative in 2 pump barrel 37 secured in the liquid supply tank 38. The pump barrel 37 is-mounted o 1 and secured to a cylindrical housing 39 se :uredto the bottom of tank 38 and provided with a, plurality of apertures 40 eommunic iting with the interior of tho tank. An opening 41 is provided through Mounted on the upper side of the'squeegee the top of housing 39 communicating with holder 62, is the liquid spraying device. the interior of pump barrel 37 "and 1s nor- This device comprises/a hollowrectangular mally closed by a flap valve 42 mounted sheet metal chamber 66 the inner edge of within the pump barrel. The pump barrel which is beveled downwardly and inwardly is further provided with an aperture 43 lo as at 67 and provided with a plurality of cated ashort distance above the bottom of perforations 68. This chamber 66 is prothe barrel and communicating with the bell vided with a rearwardly projecting nipple 4-4, secured on the side. of the barrel with 69 over which is secured one end of a flexim which communicates a liquid. discharge tube ble tube 70, of rubber or other suitable ma- 4 1,, This aperture 433 is closed by an outterial, the other end of which 1s secured yeardly opening flap valve lli mounted with over the outer end of the liquid discharge in the bell 414.
