WINDOW-WASHERS SEAT.

Application Med Julie 21, 1927. Serial No. 200,337.

orm that saidplatform, 0r Seat, may be.

placed upon the ledge of any window and its clamp means readily adjusted to the window sill to clamp the platform in position in the window frame to provide a safe means upon which the Window Washer may stand, or be seated, duringhthe time 'he is washing the windows or t e outside of the buildarious safety'appliances have been provided for the security of window washers, but none of these, lto my knowledge have utilized the principles involved in my present construction.

The primary object of my invention is to provide a safe, strong, and reliable seat, or platform, of the character designated that may be easily and qulckly placed on any window ledge and clamped thereto to provide a safe seat, or platform, forthe use of window washers in washing the outside windows of buildin s.

Another object o the invention is to provide a seat ot the class*designated that embodies in its construction a simple and readily adjustable clamping means adapting 1t to be rigidly clamped in position to the sill of a window.

Other ob'ects and advantages of my invention will be apparent with reference to the subjoined specification and 'accompanying one sheet of drawings in which:

Figure 1 is a plan view of my improved window washers seat, showing the referred construction embodying the princip es of my invention;

Figure 2 is a side elevation of the seat, showlng it mounted 4upon the ledge of a window, with its clamp means adjusted to the sill thereof;

Figure 3 is a frontelevation tion, the section being indicate 3-3, in Figure 1; and

Figure 4 is an enlarged sectional detail of one of the clamps and its adjusting screw., the section being indicated by the line 4 4, in Figure 1.

Referring more specifically to the draw partly in secby the line ings, the frame 5 preferably consists of a rectangular piece of wood, having provided on its under surface a pair of spaced angieiron braces 6 and 6 bolted thereto by a plurality of bolts 7 and 7. i

A pair of supports 8 and 8 are disposed edgewise under the frame or platform 5, and abut against the inner faces of the braces 6 and 6', with stiifenin bars 9 and 9 disposed against the inner aces of said supports 8 and 8'-, said braces 6 and 6 and bars 9 and 9', embracing the said sup orts 8 and 8', the several parts being rigidlylirolt- `ed together by rows of bolts 10 and 10 The' braces 6 and 6 extend slightly beyond the front edge of the platform 5 and embrace a transverse clamp-supporting member 11, the member 11 being provided with depending lugs 12 and' l2 adapted to. fit between the extremities of the braces 6 and 6 and the bars 9 and 9 to which said lugs are rigidly bolted.

A pairvof bosses 13 and 13 are integrally formed with the clamp-supporting member and are positioned immediatel adjacent the lugs 12 and 12 thereof, sai bosses beingprovided with tapped openings 14 and 14 adapted to receive the adjusting screws '15'V and 15, as hereinafter described.

The front ends of the supports 8 and l8 are of considerably less depth than the rear ends, as clearly shown in Figure 2, the under forward edges thereof 16 and 16 being bevelled or tapered rearwardly throughout more than half their lengt-hs, so that said supports wiil rest upon and adaptthemselves to the slant of any ordinary window sash, as indicated by the dot-and-dash lines in Figure 2.

When the seat, or platform, 5 is positioned upon the window sash, as shown in Figure 2, the upper face thereof is substantially level and the Window washer may sit or stand thereon While washing the outside through which loosely mounted handles 19 and 19 extend.

Sill-engaging hooks, or clamps,20 and 20' p l are mounted upon the bearing sections 17 and 17 of the adjustin screws, and consist of bosses 21 and 21 avin openings 22 and 22 adapted to loosely t the sections 17 and 17 of the adjusting screws shank sections 22, and inwardly projecting lugs 24 and 24 adapted to engage under the window sill as clearly shown in Figure 2.

lt is obvious that when the seat is placed upon the window sash, as shown in Figure 2, with the sill engaging hooks 20 and 20 engaging the sill, and the handles 19 and 19 are rotated, the hooks 20 and 20 will clamp the sill and draw the platform upwardl toward the rear edge t ereof until the ront end of the platform is wedged tightly thereagainst, from which position it will be imossible to accidentally dislodge the platorm from the sash. The window washer may be seated upon the (platform in the position ordinarl assume when sitting upon the sash, with is limbs extending into the room, or he may stand upon the platform and work in standing position, with a much greater degree of safety than is possible with the usual make-shift appliances.

Having thus described my invention, I claim' and desire to secure by Letters Patent: f

In a window washers seat comprising a rectangular frame consisting of a seat portion, a pair of spaced sup orts mounted under said seat portion an having their lower edges bevelled at an angular inclination relative to said seat portion, spaced bosses carried by. said frame, adjusting screws mounted in said bosses and projecting outwardly from the frame and having heads formed at their outer ends providing shoulders, means' carried by the outer ends of said screws for causingr their adjustment in said bosses, and loose y mounted clamp members carried by said screws and abutting against said shoulders and adapted for adjustment relative to said frame.

In testimony whereof l have'axed my signature.

S IMOV.
