1 Claim.

This invention relates to stagings and platforms and more particularly to an adjustable staging to be used by the vario-us artisans and workers who have to do work on vertically inclined surfaces, such as the sides of a ship.

An object of this invention is to provide a staging which can be adjusted to fit the inclination that a surface or structure makes with the vertical. n

Another object is to provide an adjustable staging with various platforms to accommodate workers at different levels above the base of said adjustable staging.

Another object is to provide a simple adjusting means for effecting thekinclination of said staging from the vertical.

Further objects and advantages of this invention as well as its construction,'arrangement and operation will be apparent from the following description and claim in connection with the accompanying drawings, in which, f

Figure 1 is an isometric view of an embodiment of this invention,

Figure 2 is a side elevation view showing the staging inclined to the right of the Vertical with the ladder omitted to clarify the showing,

Figure 3 is a cross section taken along the line 3-3 of Figure 1, and

Figure 4 is an enlarged View of the threaded member at the foot of the staging forming a part of this invention.

Referring to Figure 1, there is shown a base I which supports an adjustable staging consisting of oppositely spaced horizontal members II and I2 fixedly secured t0 the base II), and two pairs of vertical stanchions I3,v I4, I5 and I5 oppositely disposed on the4 surface ofr horizontal member II. The feet of the stanchions I3 and I4 are pivotally secured to the horizontal member II by any suitable means, and stanchions I5 and I6 are similarly secured to the horizontal member I2.

The top of stanchion I4 is broadened into a head I1 having an offset guide member I8 secured thereto to engage a bar I9, said bar I9 having shoulders to prevent slight slippage of the bar I9. The foot of the bar I9 is threaded so as to engage a threaded bolt or turn-buckle 2| which is pivotally mounted at the same junction where the vertical stanchion I3 is pivoted to the horizontal member II. The top of the bar I9 is bent into the form of a handle 22 to facilitate the turning of the bar I9.

A supportingmember 23 is pivotally mounted at its foot to the inside face of the horizontal amended April 30, 1928;v 370 0.*G. 757) member II, Said supporting member 23 rising at an angle with the vertical to pass through a guide plate 24 (Figure 4) which is suitably secured by bolts 25 or equivalent means to the inside face of the head I1. A threaded handle 26 (Figure 3) passes through a threaded opening of the guide plate 24 and is attached to a friction plate 21. 'By turning the handle 26, the friction plate 21 is urged forward to frictionally lock f.the supporting member 23 to the stanchion head I1.

Supporting member 28, guide plate 29, handle y38 and broadened head 3| are similar to and serve the same function as supporting member 23, guide plate 24, handle 26 and head I1. Likewise the bar 32 having its upper extremity bent to form a handle to facilitate the turning of bar 32 corresponds to the bar I9.

A guide member for supporting the bar 32 and a threaded bolt for engaging the threaded foot of bar 32 is obscured by supporting structure but it shouldbe obvious that they are secured, respectively, to the outer face of the head 3| and to the pivoted joint at the foot of stanchion I5.

The horizontal platforms 32 and 33 are suitably secured to the stanchions I3, I4, I5 and I8, the dovetail fitting between platform and stanchions for this embodiment of the invention being more clearly shown in Figure 2. The horizontal braces 34 and 35 are suitably mounted in stanchions I3 and I4 and serve to support said stanchions against lateral stresses. Horizontal members 38 and 31 brace the stanchions I5 and Thus it will be evident that the staging is of i symmetrical construction save for a ladder 38 which may be secured to either end of the staging. The ladder 38 is rigidly but detachably secured to offset members 39 and 4IJ that are, in turn, secured to a horizontal brace 35, the ladder being secured to the offset members 39 and 40 so as to permit the ladder 38 to hang down away from the bar I9.

In the operation of the adjustable staging the supporting member 23 is disengaged from the head I1 by turning the handle 26, then the bar I9 is rotated in clockwise or counterclockwise direction, depending upon whether the staging is to be inclined forward or backward from the vertical. The handle 26 is then turned to frictionally lock the supporting member 23 to the head I1 in the adjusted position of the staging. Meanwhile another operator is at the other end of the staging performing the same adjustments as those just described. Y

This invention is conveniently used by painters who have to do work on the sides of a ship, especially near the bow or stern. The entire staging can be lashed securely to a floating base or barge adapted to be anchored near a ship or moored thereto, the sides of said `ship being inclined .to the vertical, said inclination being different for different sections of the ship. In conventional stagings where the rigging or staging is fixed, certain painters on all levels but one are too far from the ships side as the fixed-staging is moved, in its entirety, from one section to another section of the ship. Painters who are on platforms too far from the ship's side cannot paint accurately or comfortably, and accidents .advertising signs; in fact, in any situation where the surface to be worked upon is inclined to .the vertical. When .some surfaces in a given work area are vertical and others are inclined 'to the vertical, the same staging can be used, thus diminishing the number of stagings that have to be constructed by contractors for a given building or other construction.

It is to be understood that various modifications and changes may be made in this invention without departing from the spirit and scope' thereof as set forth in the appended claim.

The invention described herein may be manufactured and used by or for .the Government of the 'United States of America for governmental purposes without the payment of any royalties thereon or therefor.

What is claimed is:

A .base adapted to float upon a liquid surface, a vertically .disposed supporting structure secured to said base, multiple horizontal platforms secured at spaced intervals along said supporting structure, multiple braces pivotally secured at an angle to said base and slidably secured to said vertically disposed structure, said braces serving to buttress -said vertically disposed supporting structure, turn-buckles pivctally secured to said base along thesides of said supporting structure,

.rotatable rods disposed diagonally along said vertically vdisposed framework and engaging Ysaid turn-buckles, the turning of said rotatable rods changing the inclination of said vertically disposed supporting framework, means to rigidly hold said rotatable diagonally disposed .rods to said vertically disposed structure, and .locking means to secure said framework after Ythe required angle of inclination has been obtained.
