The clamp 7 is further maintained rigidly positioned with respect to the bracket arms by the thumb screws 11 associated with upwardly projecting stud screws carried by the clamp.

A perpendicularframe is adjustably supported on the horizontal frame embodying a rectangular base housing 12 enclosing the horizontal frame and a rectangular perpendicular frame portion 13. .The adjustable pendicular frame embodies the provision of `rack teeth 14 rovided on the upper edges of the side wa ls 2 ofV the horizontal frame while a pinion 15 journaled in positively disposed arms 16 of the basesection of the perpendicular frame is inengagement with the rack bars for shifting the perpendicular frame longitudinally of the horizontal frame to move the same toward and away'from the A cross head supporting the window-cleaning brushes is vertically adjustable in the perpendicular frame, the cross head embodying upper and lower plates 17A suitably secured together and havin thereof extending into t e frame and spaced by the co r 18, a very' tically disposed screw rod 19 inthe perpendicular frame freely assing through sail collar and threaded lnto openings in the upper and lower plates of the cross head.

The mechanism for operating the screw rod v to shift the cross head in Yvertical directions embodies a shaft 20 journaled in the mesh with the pinion 23 secured to thelower connection between the horizontal and per-v the inner endsA erpendlcular has laterally extending rectangular skeleton frames 24 positioned forwardlyV of the perpendicular housing13, the adjacent ends 25 of the lateral extensions being spaced as 75 shown in' Fig. 5 with a screw rod having reversely threaded end portions 26 journaled in the lateral extensions while that portion of the screw rod intermediate the adjacent ends of the lateral extensions has secured thereto algear27. To operate the gear 27, a vertical shaft 28 is journaled in the perpendicular frame and has a.worm-29 secured thereto between the upper and lower plates 17 of the cross head, the lower end of the shaft 28 carrying. a pinion 30 in en gagement with a worm 31 upon the shaft 32 journaled in the horizontal frame and extending forwardly of the face plate 5 with a crank handle 23 securedy to the forwardly projecting end thereof.

A window scrubber and water supply device are associated with each lateral extension 24, the detail construction thereof being more clearly shown in Figs.A 4 to 9, each window scrubbing device including upper and lower `plates 34 enclosing th upper and lower sides of the lateralextension 24 and secured as at 35 to rectangular blocks 36 through which the adjacent end 26 of the screw is threaded with a -spacing collar'37 interposed between adjacent blocks as shown in Figa-5 and 6. VAn electric motor 38 supported between the outer ends of the plates 34' has the armature shaft 39 105 thereof extending into a housing 40, a disk 41 secured to the end of the armature shaft within the housing having an yeccentric link connection 42 with a shaftV 43' vertically reciprocable in the housing` 40. A fluid pump 44 secured to the side wall of the housingl has the piston rod 45 connected to the downwardly curved extension-13 of the shaft 43, reciprocations of the shaft being communicated to the piston rod 45 in the pump. Y 115 The window scrubber embodies a casing 46 carrying mounting screws 4 7 connected to the shaft 43 as shown in Figs. 6 and 7 with springs 48 interposed between the shaft and the shoulders 47 of the bracket screws to effect a resilient mounting'for the 'casing 46. The casing 46 is of hollow construction and has a pipe connection 49 with the pump 44, the pum being supplied with fluid through the ose 50 connected to the inlet end 51 thereof and having its other end communicating with a source of supply 52. A socket member 53 having openings 54 in the bottom wall thereof has'the perforated nozzles- 55 of the casing 46 received 130 therein, the socket member and casing being A windowcleaning device 57 such as a brush or swab is supported in the socket member 53 with theperforated nozzles 55 extending thereinto as shown in Fig. 6.

The overflow of waste water from the brush 57 is received in a pan 58 supported byv hangers 59 on the casing 40, the panhaving a hose connection '60 with the receptacle 52 whereby the same water or cleaning fluid .may be again employed. In the operation of the device, the motor 38 being operated from a suitable source of electric supply the armature shaft 39 thereof isrotated for reciprocating the shaft 43 and the lcasing 46'.and brush 57 supported on the shaft v43. The cleaning fluid in the receptacle 52 is supplied to the brush through the medium of the pum between t e armature 'shaft 39 and the shaft 43. The height of the cross head is varied by the operating shaft 20 in communication with the screw rod 19 while lateralV adjustments of the brushes 57 iis accomplished by the rod 32 rotating the shaft 28 and' having the worm and pinion connection 29-27 with the reversely threaded screw shaft 2 6.

With this device, the Window panes lA may be thoroughly cleaned upon the outer faces thereof without the necessity of a person standin upon the outer edge of a .window sill whe the several adjustments of the device will permit the brush 57 to engage the entire4 outer surface of the window pane A.
