WINDOW SEAT Filed April 17, 1931 2 Sheets-Sheet 2 NNNNNN OR W BY 0 M 60 TTTTTT Patented Nov. 21, 1933 UNITED STATES PATENT "orrioe This invention relates to devices adapted for use in connection with window cleaning, and has for its object the provision of a safe and reliable support for persons engaged in the dangerous tasks of cleaning the outside of windows where it is necessary for such persons to place themselves beyond the outer wall of the building.

A further object is the provision of a support which will afford a comfortable seat for a person employed in the task of cleaning 'the outside of windows, and which support is provided with simple means for adjustably clamping the same upon the window frame in an easy but thoroughly effective manner. Y

To the attainment of the foregoing and other objects which will present themselves the invention also consists in certain other novel features of construction, combination and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings:

Figure 1 is a side elevation of the device applied to the window casing of a frame building.

Figure 2 is a similar view showing-the device arranged upon the window casingof a masonry building.

Figure 3 is a bottom plan View of the improvement.

Figure 4. is a sectional view approximately on the line 4-4 of Figure 8.

Figure 5 is a detail sectional view approximately on the line 5-5 of Figure 3.

Figure 6 is a detail sectional view approximately on the line 66 of Figure 3.

The platform 1 of the improvement is preferably in the nature of a light but strong wooden board. The ends of the board, and if desired, the edges thereof are shod by channel metal plates 2, respectively. The under face of the board or platform 1, at points adjacent the edges thereof, is grooved longitudinally, as at 3, and in these grooves there are arranged metal strips 4.

The strips 4 have their outer ends reduced, rounded in cross section and threaded and pass through the outer shoe 2 and have screwed thereon wing nuts 5. The second or inner ends of the metal strips 4 pass through openings in the inner shoe 2 and these ends of the shoe are rounded and from thence extended downwardly to provide what I will term a stirrup 6. The lower or connecting portion for the parallel arms of the stirrup is offset from said arms in the direction of the platform 1, and has fixed on the upper face thereof a wooden cleat 7. Guided for movement onthe strips 4'there are yokes 8 secured to and extending from the center of a metal plate 9. The yokes are preferably arranged in spaced pairs on each of the plates 9 and the plates 9 are comparatively wide so that they not only cover the grooves 3 but extend a considerable distance beyond the sides of the groove and. have an ample bearing surface against the under face of the platform 1. Each of the plates is integrally formed with a depending 'iiange'lll and between the plate and the flange there is a brace rib 11. In the space between the flange and one end of each of the plates 9 there is received and secured a wooden head member 12.

Centrally secured upon thejouter face of the head 2 there is a disc member 13 from which extends a metal rod 14. The rod 14 is provided with a series oftransverse apertures 15. The platform 1, from its outer end, is centrally provided with a longitudinal opening 16, the outer end oi the said opening being closed by the outer shoe 2 and preferably the side and inner Walls provided by the opening are reinforced by a channeled metal member 17. The opening is designed to receive thereinthe body portion of a lever 18. The lever is pivoted, as at 19, to the side walls provided by the channeled member 17, and from its'pivot the lever has an offset down- Wardly inclined bi'furcated'and widened end 20 that receives therethrough the rod 14. The bifurcated end 20 of the lever is provided with an arcuate slot struck from the pivot 19 and which in the drawings is indicated by the numeral 21. There is passed through this slot and through any desired one of the apertures 15 in the rod 14 a removable pin 22. The outer end of the rod 14 is guided through an opening in an angle bracket 23 which is secured to the under face of the platform 1.

The outer end of the lever 18 has an offset extension 24 that provides a handle and said handle, when the lever is fully received in the opening 16 has its under face in contact with the outer shoe 2. To the sides of the handle 24 there are pivoted spaced ears provded upon the hand grip portion 25 of a latch. The inner end of the handle is bent angularly and merges into a thickened and toothed portion 26 which is designed to underlie and to contact with the under face of the outer shoe 2. Between the handle 24 of the lever and the hand grip portion of the latch there is a coil spring 27 which normally swings the hand grip 25 to bring the latch into engagement with the shoe 2.

The cleat 7, being of wood is compressible to a determined extent, and this cleat is designed to be received beneath and contact with the apron 27 that depends from the stool 28 in a window casing 29. The platform is of a length whereby the lever may be swung to the dotted line position disclosed by Figure 1 to permit of the cleat 7 being arranged as described so that the inner portion of the platform will rest on the stool 28 when the device is arranged ona window frame. The lever is in a position to permit of the operator gripping the same and swinging the said lever into the opening 16, and as the outer face of the toothed portion of the latch 26 is beveled, as at 30, the same will slide over the outer shoe 2 and engage therewith. The swinging'of the lever, of course, imparts a longitudinal movement to the rod and a like movement to the head 12 to bring the latter against the inner edge of the frame or casing 29 and permits the said head 12 resting on the sill for the window casing, The pin 22 is, of course, arranged in the proper aperture prior to the application of the platform on the window casing, and the proper aperture through which the pin is to be passed can be readily obtained by the operator gaging the distance between the stirrup and the outer and lower end of the window casing. The yoke may be likewise moved toward or away from the platform by the screwing or unscrewing of the wing nuts 5 on the reduced and threaded ends of the strips 4.

While I have herein shown and described a preferred embodiment of my invention it is to be understood that various changes may be made herein without departing from the spirit of the invention or the spirit or scope of the appended claims.

Having described the invention, I claim:
