WINDOW-WASH ING SEAT.

SPECIFICATION forming part of Letters Patent No. 310,057, dated December 30, 1884.

Application filed May '2, 1884. (No model.)

To all whom it 'nmy concern:

Be it known that I, WILLIAM G. Hown, of Boston, in the county of Suffolk and State of Massachusetts, hav e invented certain Improvements in IVindow-IVashing Seats,of which the following is a specification.

This invention has for its object to provide improved means for detachably securing a sea-tto a window-casing, so that it may serve as a support for a person,either in a sitting or standing position, while washing the outer surface of the window, or performing other operations, such as painting, glazing, &c.

The invention consists in a seat provided with adjustable arms arranged to grasp the wall of a building below the window-casing, and means for positively holding said arms in any positions to which they may be adj usted.-

The invention also consists in certain de tails of construction, all of which I will now proceed to describe and claim.

"Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective View of a seat provided with my improvements. Fig. 2 represents a section on line as r, Fig. 3. Fig. 2 represents a portion of the section shown in Fig. 2. Fig. 2 is a side elevationof the locking device. represents a top View. Fig. 4 represents a bottom View. Fig. 5 represents a section on line 3 y, Fig. 3.

The same letters of reference indicate the same parts in all the figures.

In the drawings, (t represents a seat, which may be of rectangular or other suitable form. I prefer to make the seat of malleable iron cast in the desired form. Secured to or formed with the seat is a bar, I), located below the seat, and extending from front to back thereof, and provided on its upper surface with ratchet-teeth Z).

crepresents a slide or block having alongitudinal aperture through which the bar 1) passes, the block 0 being adapted to slide on the bar. 011 the block 0 is formed a stout arm,

e, which is adapted to bear against the outer side of the wall w,below the ledge of a window when the seat is in place, as shown in Fig. 2. The arm 6 may be adjusted to the thickness of the wall by sliding the block 0 on the bar 1), suitable devices being'provided for engaging the slide with the bar, and positively holding the arm 0 in any position to whichit may be adjusted. In the present instance I have provided holding devices composed of a block, f, having a longitudinal slot, which receives the portion of the sliding block 0 above the bar Z), and teeth f, adapted to engage the teeth I) of said bar, and a spring, g, adapted to press the block f downwardlyand cause its teeth to engage with those of the bar '1), and a cam-lever, h, pivoted in the upper portion of the block f, and adapted, when raised, as shown in Fig. 2, to bear on the upper part of the block 0 and raise the block f, thus disengaging its teeth from those of the bar b, leaving the block 0 and its arm free to be moved along said bar. WVhen the lever his restored to the position shown in Fig. 2, it allows the spring 9 to re-engage the teeth f and b, which hold the block 0 positively, so that the arm 6 cannot be moved away from the wall 10. A slot, 1, is provided in the seat to accommodate the blocks of and lever h.

j j represent slides or bars adapted to slide in guides on the under side of the seat, and provided at their forward ends with downwardly-bent arms j j, adapted to bear against the inner side of the wall 10, as shown in Figs. 1 and 2. The slides are adjustable to adapt the arms j j to the thickness of the wall, and are also provided with devices for positively holdingthem, so as to confine the arms against the wall. To this end the slides j j are in the present instance provided with teeth k,which are pressed by springs m on bars affixed to or formed on the bottom of the seat. The springs Z bear against fixed guides at. when it is desirable to adjust the slides j, they may be moved laterally, by means of downwardly-projectinghandles it, until their teeth are disengaged from the teeth at, the slides being then free to move longitudinally. hen the desired adj ustment is effected, the springs Z force the slides inwardly and cause the teeth 7.- m to re-engage, thus looking the slides and preventing accidental movement of the arms Z away from the inner side of the wall to. Set-screws Z may be employed to hold the slides Z in engagement with the teeth m,said screws passing through the guides at, as shown in Fig. 4. It will be observed that the wall is thus tightly grasped by the arms 6 1, so that the seat is firmly secured in Z against ratchet-teeth vent injury to the wood.

place and prevented from tipping in any direction. The side edges of the seat may be provided with set-screws 1;,working in tapped lugs 12 on the seat. (See Fig. 1.) Said screws are intended to bear on the window-ledge, in

case the bottom of the seat cannot bear directly thereon, the adjustability of the screws enabling them to conform to the height or the ledge. The tapped lugs 2 may be movable in slots in the seat, so that they may be adjusted to the width of the window-sill, and may be positively held wherever adjusted by pins, set-screws, or other suitable means.

1- r r 9' represent vertical posts at the corners of theseat-supportingside rails, s. Said posts are preferably tubular and threaded interna1- ly, so that longer vertical rodsr can be screwed into them to serve as guards fora person standing on the seat, their upper ends being eonneeted, if desired, by a cord or chili-11,25. Said rods may be lengths of gas-pipe, and when they are not required for use they may be rea dily removed from the sockctcd posts r. Instead of being screwed into the sockets r, the rods 1' may be held in said sockets by friction.

it represents an arm or bracket adapted to be secured either to one of the posts 1' or to one of the rods 0', and hold a pail or other vessel that may be required. Said bracket has two bosses, '0 cone adapted to enter the socket of one of the posts 1', and the other, of smaller size,adapted to enter the end ofone ofthe tubular rods 1'.

All the parts of my improved seat are preferably made of metal. The upper surface of the seat may be provided with a covering of fiber, such as is used for chair-seating. The parts of the arms j which bear against the wood-Work may be covered with rubber or other comparatively yielding material to pre The arm 0 may be similarly covered, if desired, although in most jj may be permanently attached to the seat,

so as to be non-adjustable.

The adjusting devices for the arms and the means for positively holding the arms after adjusting them may be variously modified.

I claim 1. A window-washing seat having toothed bars m, armsj j, having hooks at their inner ends, and ratchet-teeth engaging the teeth on bars in, bloclcc, through which a ratchet-bar on the seat passes, and locking mechanism, whereby the ratchet-bar and block 0 may be held in engagement, all combined and rela tively arranged, substantially as stated.

2. In combination, a slotted seat provided with a longitudinal raek-bar and a movable block on a movable supporting-bracket engaging said rack, said seat also having side rackbars engaging adjustable supporting hookarms, the specified elements relatively arranged substantially as shown and described.

The combination, with the seat a, of the hooked bars j j, adjustably secured thereto, the block 0, having bar 0, also adjustably secured to the seat, and the adjustable bearingscrews arranged, as described, to bear on the window ledge, all substantially as shown and described.

4:. The bracket 11, provided with bosses v r of different sizes, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subseribin g witnesses,this 29th day of April,1884.
