T0 all whom t may concern.'

Be it known that I. JAMES A. BLAoKwooD, a citizen of the United States of America, and a resident of Jersey City,in the county ersey, have invented a new and Improved Window- Cleaners Seat,.of which the following is a description.

e present invention relates to new and improvements in window cleaners seats.

It is one of the to provide a anchored to a objects of the invention window sill in posit'on person washing the window s'tt-ing thereon.

It is a further object of the invention to construct a seat of this character in such a manner that it will occupy a horizontal plane although used upon w ndow sills having an upper inclined face as commonly constructed.

It is a further object of the invention to construct the Wlndow seat in such a manner that 1t 1s adjustable for use in connecto persafely v tion with Window sills of different pitch and dimensions. v

With the above and other objects in view, reference is had to the accompanying dra-wings in which igure 1 is a view partly in elevation and partly in section of a window cleaners seat constructed in accordance with the present invention:

Figure 2 is a bottom plan view thereof. Referring more particularlyv to the drawings the reference character 5 designates a. Window sill and said window sill is inclined as shown in Figure 1. The reference character 6 designates the seat and said seat is provided on its under face with two support-ing blocks 7.

Secured to one end of the seat 6 are hooks 8 and said hooks are provided with a. suitable lining 9 to prevent scarring the front end -of that portion 10 of the window sill with which the hooks 8 engage.

e supporting blocks 7 are secured to the seat by bolts'll. there being one bolt. for each block through an elongated slot 12 formed in the bottom of a recess 13 yin its respective snpporting block.

Seat which will be securely and each of said bolts passes b l engaging provide with a channel or cut-out portion 14 in its rear end and said channels or cut-out portions 14 are adapted to receive guide pins 15 carried b v the seat 6 to prevent swinging movement of the supporting blocks about their bolt 11. e groove or cut-out portion 14 also permits of longitudinal movement of the blocks to permit of adjustment.

The device is used in the following manner:

The hooks 8 are supporting blocks 4 with the member 16 of the sill 5 is Each of the engaged with the portion 10 of the window sill as shown in Figure 1 after which the seat is dropped to a horizontal position and the blocks are adjusted so that their foot portions 15 will rest on the window sill 5 adjacent the member 16 thereof. When the blocks have been so positioned. it will be apparent that the seat can be removed only b v elevating the rear end thereof, sliding movement of the seat being prevented in one direction b v the hooks 8 and in the other direction bv the foot portions 15 of the blocks 7.

From the forego`ng it is apparent that the present .invention provides a window seat which is capable of securement to a window sill in such a manner as to prevent sliding movement or accidental displacement thereof. Furthermore. a seat constructed in accordance with the invention is adapted for use in connection with windows of va.- rious styles and dimensions.

H( ving thus described my invention, what claim is:

A window cleaners seat, comprsing a. platform provided with hooks at its front end and on its underface intermediate of its ends with pins, two blocks on the underface of the platform, each block having the underface of its front end rabbeted and provided in the underface of the rabbeted portion with a longitudinally extending recess and a slot leading from the recess out throughv the top of the rabbeted portion, the rear ends of the blocks being provided in their upper faces with longitudinal grooves to receive the pins of the platform` o ts passingrthrough the platform and the slots of the blocks into the recesses thereof and nuts on the bolts in said recesses.
