Application filed May 1, 1915. Serial No. 25,163.

To all tvhom it may concern:

Be 1t known that 1, CHARLES RUDoLr, a citizen or" the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in lVindow-Cleaning Devices, 0 which the following is a specification.

This invention relates particularly to window-cleaning devices adapted to the purpose of simultaneously cleaning both sides of a window. Such a device is particularly use ful for cleaning windows of otiice buildings, or the like, inasmuch as it can be used without endangering the life or limb of the operator.

The primary object is to provide a. window-cleaning device which will operate effectively to clean both sides of a. window, and which shall be of simple, cheap and durable construction.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure 1 represents a broken sectional view of a window with my improved window-cleaning device mounted for cleaning the window; Fig. 2, an enlarged broken sectional view taken shown in Fig. 1; Fig. 3, a horizontal sectional view taken approximately as indicated at line 3 of Fig. 2; Fig. 4, a sectional view taken as indicated at line 4. of Fig. 2; Figs. 5 and 6, broken sectional views taken as indicated at the corre ponding lines of Fig. 2; Fig. 7, a broken sectional view showing the construction of one of the elbows; Fig. 8, a broken view illustrating the manner ingvhich the cleaning tool isapplied to the device; and Fig. 9, a section taken as indicated at line 9 of Fig. 8.

. a In the preterred construction, which is illustrated, A represents a base-plate adapted to lie across a window-sill and be adjustably secured thereto; Bpa mounting adjustable longitudinally in the plate A and equipped with rock-shaft bearings B and sash-supports 13 G, a large tubular rock shaft rotatable in the bearings B D, D a pair of lower or main arms connected by pivots. or shafts, l to bearings, with which the end-portions of the tubular rock-shaft C are equipped; E, E a pair of upper or forc arms forming elbows with the arms D, with which they are connected by pivots 2; F, F wiping devices, or tools, of any suitable character, pivotally and detachably carried by parallel with the section the upper ends of the arms E, E; G, G racks,

or rack-equipped slides mounted in the arms D, which are preferably tubular, and having their upper ends engaging gearfsegments 3, with which the lower ends of the arms E are equipped, and having their lower ends engaging gears 4; mounted on the shafts 1; G a rack slidable through the tubular rockshaft C, and meshing at one end with one of the gears 4, and at the other end with an 1dlergear 5, which meshes with the other gear 4; and H, H a pair of racks slidable through the rock-shaft G and meshing at one end with gear-segments 6, with which the lower end of one of the arms D is equipped, and meshing at the other end with idler-gears 7, which, in turn, mesh with the gear-segment 6, with which the base-portion of the other arm I) is equ pped.

The construction is such that the arms D have universal connection, through the medium of the pivots 1 and the tubular rockshaft C, with the mounting B; also, such that the movements of one arm D are duplicated by ments of one arm other arm E.

K represents the window-frame, which is equipped with a sill-plate 8; and K represents the window-sash carrying the glass K".

The base-plate, or sill-carried plate A, is provided with a guide 9, on which the base- E are duplicated by the portion of the mounting B isfllongitudinally adjustable, said mounting being secured, when adjusted in the guide 9. by a set-screw 10. The member A has one end provided with a bracket 11 having a clamping-screw 12, for engaging the inner edge of'the ledge of the window-sill, and having a' clamping- I screw 13 for engaging the lower margin of the ledge of the window-sill. The body of the member A. is equipped with a lug 14, which carries a clamping screw 15 adapted to engage the outer edge of the top member of the window-sill 8. as shown in Fig. 1.- The outer end of the member A is equipped with a set-screw 16,- whose lower end is adapted to bear on the outer portion of the window-sill.

. The bearings D which flank the sashsupports B are provided with suitable bores to receive and permit rotation of the tubular rocloshaft C. ()neot the bearings B is-providcd with a circumferential slot 17. in which works a stud 18 carried by the rock-shaft C, thus limiting the rotation of the other arm D, and the 'movethe rock-shaft. in its bearings. The rockshaft is free 'to turn, however, sufficiently to perm t the tools F to swing downwardly to the plane, or below the plane, of the rock shaft. The sash-supports B which are on opposite sides of the rock-shaft C, are re cessed at. their upper ends to accommodate the lower edge portion of the sash H The tubular rock-shaft G contains in its lower portion an insert. or lillet, C which is provided with guides for the rack G and the racks H. H. The member 7 is provided a each end with a pair of bearings 19. 19 and a pair of bearings 20, 20, through which the shafts, or pivots. 1, extend: and at one ent of the rock-shaft said bearings support the pin' or shafts, E21 and on which the idlers n and T are mounted, "respectively.

The racks 4' G are suitably mounted to slide in the tubular arms D, D. ()ne of the ar F. equipped near its upper end with hail). or handle. 22 by means of which the de\ ire mav be operated.

As will be understood from Figs. 8 and 9, each tool. or wiper, F which may comprise a sponge, mop or squeegee) has or includes a plate 24, which is detachably mounted on lugs 25, with which the upper end of the arm E is equi in'icd. in the illustration given, the plate 2% has its outer or back surface quipped with lugs 26. one of which has a atria-pivot 2G entering the adjacent pivot- 25 of the arm E; and the pivot connection at the other lug 25 is provided by the pririg-projected plunge r 27 equipped with a thumlrpiece 28. The thumb-piece 28 is disposed opposite a finger-piece 29 carried by the lug 26, which carries the stub-pivot l v the means described. the tool I may be ren acd at will from the arm E, and an other tell substituted. or a fresh cloth. or wiping: portion. applied. as the case may be.

* usc'of the improved device, the -'-'nlate A is securely clamped to the i l. and the sash is lowered to rest .aash-sup mrts il the mounting B lasing; suitably adjustcd in the clampingll; .l. The operator then. through the medium of the handle 23. actuates the arm ch is inside of the window, thus movcorrcsponding tool over the inner 1 cc of the glass in any desired direction. The movements of the actuated arm lliare commuuiratcd through the corresponding rack ti. the raclc i and the other rack G, to the duplicat; arm F1: and the movements of the arm which is near the operator, are

nnnmnicalcd through the rack G to the other arm l7. Thus. the tools F are given corresponding movements. and both the in no and outer surfaces of the window are cleaned.

The device described is simple. easily operated. and the tools or wiping devices are capable of a large range of movement.
