1 Claim.

This invention relates to that class of invenhaving to do with scaiolds, seats, chairs and the like expressly designed and used by painters and window-washers to expedite safe v5.: completion of an appointed task.

am admittedly aware of types of seats and chairs have Being generally conversant with the state of e prior art to which the invention relates, I the fact that various been designed and adapted for use to promote expeditious and safe window Washing. It follows, therefore, that it is my primary aim to generally improve upon these eviously known structures by providing one characterized by structural renements and distinctions calculated to provide appreciable improvements such as transcend the prior structures and in so doing to promote economy, efficiency, stability and safety.

Briefly stated, the preferred embodiment of e invention is characterized by the incorporation therein of an appropriately shaped seat ard designed for dependability and comfort, id seat board being equipped with a foldable back-rest for compactness and convenience, and

and fastening means complemental adaptation aptly iitted for maintainrther provided with ing the chair in an adequate manner on the window sill.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings. I

In the drawings, wherein like numerals are employed to designate like parts throughout the me: Fig. l. is an elevational view of the improved occupant chair illustrating the preferred construction and the manner in which it is at'- tached.

back-rest folded down Fig. 2 is an elevational view with the chair deched from the window sill and showing the to collapsed position.

Fig. 3 is a front view of the structure illuschair being removed from e window.

Fig. 4 is a top plan view illustrating principally the construction and design of the seat board and the clamping or retention means.

through the plate Fig, 5 is a transverse detail sectional View portion of the adapter or clamping bracket, the section being taken on the plane of the line 5-5 of Fig. 4.

Fig. 6 is a detail perspective view of an especialdesigned stabilizing clamping member.

Fig. 7 is a longitudinal sectional view on an enlarged scale, taken approximately on the plane of the line l-1 of Fig. 4

Referring now to the drawings by distinguishing reference numerals, it Will be observed in Fig. 1 that the window frame is denoted as a unit by the numeral 8 and the stepped window sill is distinguished by the numeral 9. The chair is so constructed as to adapt it to lit this stepped or conventional type window sill.

The seat board of the improved chair is denoted by the numeral I (i and is of appropriate proportions and material. It is here shown as being in the form of a saddle and the rear end or cantle portion is provided at opposite corners with keeper notches II. The central forward extension I2 which may be distinguished as the pommel is of suitable narrowed configuration and terminates in a straight-cut end I3 which constitutes an abutment and is designed to rest against the ledge portion in the angle 9a of the window sill in the manner shown in Fig. 1. Hence, this extension constitutes a stabilizing pommel as well as a carrier for the clamping means.

The clamping and retaining means which cooperates with the extension or cantle I2 comprises essentially a hanger unit including a rectangular adapter plate I 4 terminating in a padded hook I5 to engage over the ledge of the window sill as shown in Fig. l. As indicated in Fig. 5, the adapter plate which is longitudinally elongated and rectangular is formed with a longitudinal central slot IS to accommodate the threaded end of the bolt Il carried by the pommel I2. On opposite sides of this slot, I provide spaced parallel teeth I8 which may be described as retaining or rack teeth. The thumb nut I 9 on the threaded end of the bolt is adapted to cooperate with a ratchet plate 2li. This ratchet plate is of suitable proportions and preferably square and provided on its bottom with ratchet teeth 2l to engage adjustably with the rack teeth I 8. In addition, there is a central aperture in` the plate to accommodate the bolt and nut and in alignment with this are depending lugs or detents 22 which serve as stabilizing and guide fingers and which slide in the longitudinal slot I6. It is evident therefore that this hooked adapter unit makes it possible to t the seat board to Window sills of varying proportions. It is observed that the hook lies in a plane to cooperate eiiiciently with the abutment or terminal I3 of the extension` I2.

On the bottom of the seat board, I provide a pair of companion or complemental stabilizing cleats 23. These are in the form of vertically disposed wooden cleats, the lower edges 23 are inclined to conform to and rest in a solid manner upon the adjacent surface of the stepped part of the window sill `as shown in Fig. 1. The inner ends 25 serve as rests and engage iirmly behind the angular shoulder 9b on the window sill. This makes for rigidity and safety of maintenance of the seat board. In other words, it also Yprovides for balance and stability and insures expeditious application and effective maintenance.

The next part of the structure to be observed is the back rest 26. appropriately shaped and proportioned frame which includes vertical end members or frame pieces 21 which are attached by hinges 28 to the seat board which have their lower end portions Vextending down into the keeper notches Il.

With this arrangement, it is evident that a comfortable seat and back rest is -provided for theuser or occupant. Then too, when the device is not in use, the backrest can be folded down against the seat board as shown in Fig. 2 to provide for compactness and convenience in handling, shipping and storage.

Admittedly, although there are no radical structural differencesl in thedevice herein illustrated, there are certain evident improvements and refinements which, it is believed, warrant favorable reception by the trade and unqualified endorsement by the average user.

This is in the form of an f clamp carrier, a

, It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

l'. claim: Y

In a structure of the class described, a seat board, a hinged back rest attached thereto, said seat board being formed on its forward edge with an extension constituting a pommel and clampof thepommel and including an attaching hook v and a slotted adapter plate, a bolt carried by Y said pommel and including a nut co-operable adapter plate, and a pair of reinforcing cleats on the underside of said seat board, said cleats terminating short of said extension, said adapter plate being formed on opposite sides of the slot with rack teeth, and a with said slotted ratchet plate superimposed on said adapter plate and including lugs slidable in said slot and ratchet teeth co-operable with said rack teeth, said ratchet plate being further co-operable with said bolt;
