WINDOW-WASHING DEVICE.

Specication of Letters Patent.

Application filed October 27, 1916. Serial No. 128,127.

To all 'whom t may concern:

Be it known that we, GIUSEPPE BERTO- LINI and ToMAsso CAPPELLETH, subjects of the King of Italy, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Window-Washing Devices, of which the following is a specification.

Our invention relates to improvements in window washing devices and has for its object the production of a device of this character through the medium of which the outer side of a window may be readily and easily washed without the necessity of the operator or washer passing through the window to the outer side thereof, theconstruction being such as to permit of the washing of the outer side of a window by an operator positioned at the inner side of the window. A further object is the production of a device, as mentioned, which will be of durable and economical construction and elcient in use. Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a vertical section through a window in conjunction with which is arranged a window washing mechanism, embodying the invention,

Fig. 2 is an elevation of the construction shown in Fig. 1, viewed from the outer side of the window,

Fig. 3 is an elevation viewing the window and washing mechanism from the inner side of the window,

Fig. 4 is a section taken on substantially line m-m of Fig. 1, and

Fig. 5 is a detail section illustratin the method of actuation of the lazy tong evice included in the construction.

The preferred form of construction as illustrated in the drawings is designed for usein connection with a conventional window sash 1 which is slidably mounted in a window frame 2. The mechanism comprises a guide rail 3 inthe form of a T iron which is adapted to rest upon the outer sill of the window adjacent the lower edge of the window sash, the latter being raised slightly to permit of insertion or application of the mechanism. The rail 3 is held in proper position by means of hooks 4 carried thereby which are adapted for engagement with eyes or loops 5 provided upon the inner sill of the window.

Mounted for travel upon the rail 3 is a carriage 6 at the upper side of which are provided two spaced wheels 7 adapted for engagement with the upper side of said rail 3. To insure travel of the wheels 7 along the rail, said wheels are provided at. their peripheries with spaced radial pins which are adapted for engagementwith spaced perforations 8 formed in the rail, as seen. Also provided in the carriage at the under side thereof are four wheels 9 which are adapted to engage with the under side of the upper fiange of the rail to hold the carriage secu'rlely in the travel of the same along the ral The wheels 7 are loosely mounted upon a shaft 10 which is rockingly mounted mthe carriage 6, the inner end of said shaft being adapted to project through the opening below the window sash, as clearly shown in operating with the outer end portion of the shaft 10 is a lazy tong device comprising an elongated guide armll in the form of a T iron which 1s secured rigidly to said shaft.

Patented Mar.. 19, 1918-.

Coperating with guide arm 11 is a lazy I tong member 12 having angularly formed enga ing lingers 13 which are adapted to slida ly engage with said arm, as clearly shown in the several views. gers 14 of the lazy tong member are held fast to the arm 11 by means of pins 15, as clearly shown in Fig. 2. The arrangement is such that. said lazy tong member may be extended and contracted by sim ly oscillating the lower diverging ends o the lowermost links of said lazy tong member. A helical tension spring 16 interposed between and connecting said lower ends of said lowermost links serves normally, to hold the lazy tong member in extended condition. Contraction of said lazy tong member is effected by means of two spaced gears 17 The lower finioo which are rotatably mounted upon the inner side of arm 11 adjacent the lower end thereof. Links 18 serve to connect the gears 17 withA the lower ends of said lower links, as clearly shown in Fig. 5. The gears 17 mesh with an idler gear 19 which, in turn, meshes with a gear 20 which is xed to a shaft 21 rotatably mounted in bearings provided in the lower end portion of arm 11. The arrangement is such that, through rotation of shaft 21, the divergently disposed lower ends of the lower links of the lazy tong membermay be rocked upwardly in order to contract saidI lazy tong member.

With this arrangement then it will be seen that expansion and contraction of the lazy tong member may be effected with ease and rapidity by simply rotating the shaft 21,

since, when this is done, the links 18 willeffect contraction of said member and the spring 16 expansion of the same. A hand wheel 21 is provided at the inner end of' shaft 21 for manual engagement.

Carried at the upper end of the lazy tong member 12 is a brush 22 which is adapted, upon actuation of said lazy tong device, to engage with the outer side of the window pane, as clearly shown in Fig. 1. The back of said brush is formed with a semi-circular slot 22 with which slidably engage headed pins 22 which are provided at the upper ends of the uppermost links of the lazy ton member. 4

C eansing liquid is supplied to the brush 22 through the medium of a pum 23 which is mounted upon the lower en of guide arm '11, said pump being operated upon rotation or oscillation of the shaft 21. A supply pipe or hose 24 communicates with the lower end of said pump, said pipe or hose being connected with any suitable source of supply, a pipe or hose 25 extending from the upper end of said pump to thel brush 22, as seen. v

Pivotally connected at 26 with the inner end of shaft 10 is an angular handle 27 which is normally held in elevated position by means of a helical tension spring 28, a pawl or dog 29 pivotally connected with said handle and which is adapted to engage at its outer end with a recess 30 provided 1n said shaft, serving to lock said handle in operative position.

With the construction set forth it will be seen that in the washing of a window, the sash is first slightly elevated and the rail 3 arranged upon the window sill, being locked in position by hooks 4. Similar hooks 3l are preferably provided for engagement with eyes 32` provided upon ythe sash for locking the latter in the desired elevated position. The device having been arranged, as shown, and the water supplied through the pipe 24 to the pump 23, 1t is only necessary to actuate the handles 21 and 27 in order to effect actuation of the lazy tong member, both in the way of extending and contracting the same, oscillating said member laterally and moving the same bodily along the rail in order to effect moving of the brush 22 to engagement with all parts of the window in the cleansing operation. The brush is automatically supplied with water during the actuation of the same, so that a thorough cleansing of the window is ei'ected.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, thiseis capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be 'limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
