WINDOW-CLEANERS SEAT.

Specification of Letters Patent.

Application filed June 10, 1911.

Patented July 23, 1912.

Serial No. 632,465.

The object of this invention is to provide.

a window seat for window cleaners which will be safe, convenient and comparatively cheap to manufacture.

A further object of this invention is to have it so arranged as to be readily adjusted to conform to the shape or slope of any window sill, and also to provide means whereby the adjusting parts may be fastened securely in position, so that the window seat may be removed from window to window in the same house without further readjustment.

Another object of this invention is to provide means whereby the weight will be distributed directly to the window sill and not to the woodwork surrounding the interior portion of the window frame, at the same time means are provided so that the woodwork of the window will not be marred in any way by the device.

Further objects of this invention will become apparent as it is more fully set forth.

WVhile there are many types of window seats used by window cleaners, they are more or less objectional because of the marring effects they have on the woodwork of the window, which makes owners of houses forbid their use, and thereby force the window cleaner to use the more dangerous method of cleaning the windows by standing on the sill. Other window seats are so complicated that they will not be used by window cleaners, because they entail too much labor in installing them. There are also many other window seats which can be adjusted to a greater or less extent, but the adjustment has to be undone every time the seat is removed to another window, and reset up.

In this invention the adjustment is made very easily, and thence set, so that the window seat can be taken to various windows throughout the house without further readjustment. At the same time the means for securing the device to the window sill is simple and can be readily adjusted to suit the conditions arising. While at the same time it does not interfere in any way with the means for adjusting the seat that accommodate it to the slope of thesame.

A particular advantage of my window seat is that the weight of the person sitting thereon falls almost entirely on the window sill, so that practically all the strain is eliminated from the hook which engages with the interior woodwork of the window frame; thus making the seat perfectly safe. There is also provided a cushion on the end of the hook where it engages with the finished woodwork so that the same will not mar the woodwork in any way.

There are many advantages in this device which will become apparent as the specifications are read, and reference had to the accompanying drawings in which;

Figure 1 represents a bottom view of the seat embodying this invention; Fig. 2 is a longitudinal section along the line 22 of Fig. 1, and Fig. 3 is atransverse section along the line 33 of Fig. 1.

Similar reference characters refer to similar parts throughout the drawings.

In the drawings 1 represents a main body portion or sitting surface of window seat, which has a pair of braces 2 extending from the front and circular portion 3 of the seat body 1. The braces 2 are intended to strengthen the seat and are preferably of a I somewhat rectangular cross section, but beveled close to the outer ends as is clearly shown in Fig. 1. The braces 2 do not extend to the back end of the seat body 1 but stop a certain distance therefrom and the remaining distance between the back edge of the seat body and each brace 2 has a cushion piece 4 which is preferably of rubber and arranged so as to rest upon the window frame itself in the manner clearly shown in Fig. 2, so that the frame will not be marked up.

In the central portion of the seat body is disposed an adjustable hooked beam 5 which is provided with two slots 6 and 7 arranged to receive thumb nuts 8 and 9 or like devices, which are arranged to secure it to the said body in any position that is desirable. This beam is recessed into a groove 10 provided the beam can slide. The outer hooked portion 11 of the beam is provided with a rubber sleeve 12, or a sleeve of some similar material which will permit the hook to en gage with the window without marring the same.

13 and 14 are threaded bushings recessed into the body 1 to receive and hold the threaded portion of the thumb nuts 9 and 8 respectively.

Secured to the body 1 is a pair of hinges 15 and 16 disposed close to the braces 2 and which have disposed on their outer ends rounded pieces 17 which are arranged to engage with wedged pieces 18 that are provided with plates 19 secured at their inner portions, and are slotted, as is clearly shown, so that the wedges can be held securely in any position that they are adjusted to. Provided on the outer sides of the wedge pieces are a pair of angle plate guides 21 which are secured in any suitable manner to the body 1. A bar 22 is secured to the bottom portions of the pieces 17, and is arranged to come in contact with the outer sill of the window, and rest thereon, and also to transmit the greater part of the weight of the window seat and that on it, to the window sill.

In order to keep the hinges 15 and 16 from falling down as the window seat is raised from a window, there is provided a pair of springs 22 which engage with the lower portion of the hinges which are suitably secured to the braces 2, these springs tend to force the hinges up against the wedge pieces 18, and keep them there tightly, under normal conditions.

In operation the seat is placed out of the window in an ordinary manner and the end portion of the braces 2 engaged with the outer edge of the woodwork of the window, then the hook 11 is placed in contact with the one edge of the woodwork as clearly shown but in such a posit-ion as to keep the braces in contact with the woodwork just mentioned, the hook being in position, the thumb nuts 8 and. 9 are fastened on the same to hold it securely in position. Should the window seat tip at an angle on account of the slope of the window sill proper, the wedge pieces 18 are then driven inwardly until they raise the seat to its proper level. The bottom edges of these wedges engage with the rounded and upper portion of the pieces 17 on which they form a resting place when in position. WVhen the wedges are in place the screws or thumb nuts 20 aretightened so that the wedges are held securely in place. WVhen it is desired to move the seat off the window, whether to be used in another window or to be stored away until needed, it is removed by catching hold of the outer portion of the seat and simply lifting it. up, this will cause the hook to disengage from the sill, because sufficient play is left there to permit it, and the seat can be lifted free from the window, and still the seat will be firm enough in use to prevent any wabbling or any other undesirable motion. It can be placed upon another window sill by simply engaging the hook with the window sill.

Referring particularly to the part- 17 shown in Fig. 3 of the outer edge of the window sill, these are provided in order that windows which are arranged with a subsill that presents an off-set surface will not interfere with the use of this device. They are provided for the purpose of throwing the bar 22 farther downward so as to overcome any such off-set, and prevent the hinged part from striking the upper sill. Thus it can be seen that this window seat can be adapted for practically all classes of windows.

It will be noticed that the device is very simple because its parts are comparatively few also that its adjusting means are simple,

but positive in their action and at the same time the general cost of such a device is com paratively small, and is one that is particularly desirable because it has all the features of safe-guarding, that such seats are particularly intended to have, at the same time, they enable the window cleaner to' clean the window much more quickly, and much better because they afford a means by which every part of the window can be easily gotten to.

Obviously while there is shown but one form of the invention in these drawings it is not desired to limit this application for a patent in any way, otherwise than necessitated by the prior art as many modifications of this invention can be made without departing from the principles thereof.

Having thus described the invention it is claimed:

1. A seat of the class described comprising in combination a seat proper having a central groove recessed in the bottom portion thereof, a hooked beam slidably adjustable in said groove, a rubber sleeve disposed on the end of said hook, a plurality of hinged members secured to said seat and adapted to rest on the sill of a window, a plurality of wedges for raising and lowering the seat adjustably secured to the bottom portion of said seat, a plurality of braces disposed on the bottom portion of said seat and arranged to engage with the sill of a window so as to form a locking means for said window, substantially as described.

2. A seat of the class described comprising in combination a seat proper having a central grooverecessed in the bottom portion thereof, a hooked beam slidably adjustable in said groove, a rubber sleeve disposed on the end of said hook, a plurality of hinged members secured to said seat and adapted to rest on the sill of a window, a plurality of wedges for raising and lowering the seat adjustably secured to the bottom portion of said seat, means acting in connection with said beam for removably holding said seat to a window sill, said means being arranged to permit the removal of said seat without requiring the unloosen- 10 ing or disengagement of any of the parts of said seat.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses. CARL LINDEN. Witnesses:

FLORENCE I. LITTLE, G. L. WARUKEN.
