JOHN STERNAD, OF JERSEY CITY, NEW JERSEY.

CHAIR FOR CLEANING WINDOWS.

Application filed October 29, 1915.

To all whom it may concern:

Be it known that I, JOHN STERNAD, a c1t1- zen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Chair for Cleaning V111- dows, of which the following is a full, clear, and exact description.

My invention relates to chairs for cleaning windows, and an object thereof is to provide a simple, inexpensive and convenient chair whereby window cleaning is rendered safe.

Another object of the invention is to pr0- vide a chair for window cleaning which can be collapsed so that the same may be stored in a comparatively small space.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a fragmentary, perspective view of a building to the window of which my chair is secured; Fig. 2 is a plan view of the seat section and the support therefor detached from the seat and shown collapsed;

and Fig. 3 is a section on line 33,' Fig. 1.

Referring to the drawings, 4 is a seat section in the shape of a rectangular board. Rows of U-shaped staples 5 are secured to the underside of the board. Each row straddles a bar 6 of a seat support 7. An upwardly extending arm 8 is formed at the outer end of each bar by bending a portion of the arm up. The ends of said arms are spaced by a rod 9 pivotally connected to the arms, whereby the bars can be swung, as shown in Fig. 2. The inner end of each bar is preferably provided with an extension 10 having a hook end 11 for engaging a window frame interiorly.

The extensions are secured to the corresponding bar 6 by bolts 12 adapted to pass through a set of registering holes 13. This adapts the chair for walls of different thicknesses. /Vhen the window frame has no interior molding to be engaged by the hooked Specification of Letters Patent.

Patented Aug. 15, 1916.

Serial No. 58,528.

1 ends 11, a bar 14 may be placed transversely of the window and engaged by the hooked ends, as illustrated in Fig. 1. Each of the bars 6 is provided with a loop 15 forming a brace for engaging the wall below the window and maintaining the seat 4; substantially horizontal.

To strengthen the chair back and to pro vide side guards, chains 16 are secured to the eyelets 17 of the rivets which connect the rod 9 to the arms. A link of said chains is engaged to hooks 18 provided on the extensions 10. It will be noted that when the chair is not in use, the support 7 formed by bars 6, arms 8 and braces 15 can be folded as shown in Fig. 2, so that the chair can be stored in a narrow space.

IVhen the chair is to be placed in position for cleaning a window, as shown in Fig. 1, the bars 6 are unfolded and the hooked ends 11 are made to grip the window frame interiorly with the braces 15 in engagement with the outer surface of the building Wall. The seat 4: is then placed on the bars. The engagement of the staples 5 will prevent any relative movement of the bars. A person occupying the chair, therefore, will be perfectly safe, for the arms 8 of the bars 6 and the rod 9 form a back for the chair against which the person may safely lean. A protecting belt may be secured to the eyelets 17 to encompass a person occupying the seat.

I claim:

A chair for window cleaning comprising JOHN STERNAD.

B. Jorrn, PHILIP D. RoLLHAUs.
