(01„304-2) (Granted under the act of' March 3, 11883,' as amended April 30, 1928;v 370 0.*G. 757) 2 1 This invention relates to stagings and plat forms and more particularly to an adjustable staging to be used by the vario-us artisans and workers who have to do work on vertically in clined 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 inclina tion that a surface or structure makes with the vertical. ' n Another object is to provide an adjustable stag ing with various platforms to accommodate work ers at different levels above the base of said ad 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 se cured by bolts 25 or equivalent means to the in side 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 fric tion 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 justable staging. y38 and broadened head 3| are similar to and Further objects and advantages of this inven tion as well as its construction,'arrangement and to form a handle to facilitate the turning of bar 32 corresponds to the bar I9. serve the same function as supporting member Another object is to provide a simple adjust ing means for effecting thekinclination of said 15 23, guide plate 24, handle 26 and head I1. Like wise the bar 32 having its upper extremity bent staging from the vertical. operation will be apparent from the following description and claim in connection with the ac A guide member for supporting the bar 32 _and a threaded bolt for engaging the threaded foot companying drawings, in which, f Figure 1 is an isometric view of an embodi of bar 32 is obscured by supporting structure but the ladder omitted to clarify the showing, ably secured to the stanchions I3, I4, I5 and I8, the dovetail fitting between platform and stan chions for this embodiment of the invention be ing more clearly shown in Figure 2. The hori zontal braces 34 and 35 are suitably mounted in it shouldbe obvious that they are secured, re spectively, to the outer face of the head 3| and ment of this invention, to the pivoted joint at the foot of stanchion I5. Figure 2 is a side elevation view showing the The horizontal platforms 32 and 33 are suit staging inclined to the right of the Vertical with 25 Figure 3 is a cross section taken along the line ‘ 3-3 of Figure 1, and .

Horizontal Referring to Figure 1, there is shown a base I0 members 38 and 31 brace the stanchions I5 and which supports an adjustable staging consisting I6. of oppositely spaced horizontal members II and Thus it will be evident that the staging is of i I2 fixedly secured t0 the base II), and two pairs 35 symmetrical construction save for a ladder 38 of vertical stanchions I3,v I4, I5 and I5 oppo which may be secured to either end of the stag sitely disposed on the4 surface ofr horizontal ing. The ladder 38 is rigidly but detachably se member II. The feet of the stanchions I3 and cured to offset members 39 and 4IJ that are, in I4 are pivotally secured to the horizontal mem ber II by any suitable means, and stanchions I5 40 turn, secured to a horizontal brace 35, the lad der being secured to the offset members 39 and and I6 are similarly secured to the horizontal 40 so as to permit the ladder 38 to hang down member I2. away from the bar I9. The top of stanchion I4 is broadened into a In the operation of the adjustable staging the head I1 having an offset guide member I8 se cured thereto to engage a bar I9, said bar I9 45 supporting member 23 is disengaged from the having shoulders 20 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| head I1 by turning the handle 26, then the bar I9 is rotated in clockwise or counterclockwise di rection, depending upon whether the staging is to be inclined forward or backward from the which is pivotally mounted at the same junction where the vertical stanchion I3 is pivoted to the 50 vertical. The handle 26 is then turned to fric tionally lock the supporting member 23 to the horizontal member II. The top of the bar I9 is head I1 in the adjusted position of the staging. bent into the form of a handle 22 to facilitate Meanwhile another operator is at the other end the turning of the bar I9. of the staging performing the same adjustments A supportingmember 23 is pivotally mounted Y ' at its foot to the inside face of the horizontal 55 as those just described. 2,406,786 3 4 This invention is conveniently used by paint It is to be understood that various modifica tions and changes may be made in this invention ers who have to do work on the sides of a ship, especially near the bow or stern. The entire stag ing 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 in clined .to the vertical, said inclination being dif ferent for different sections of the ship. In con ventional stagings where the rigging or staging is fixed, certain painters on all levels but one are too far from the ship’s 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'ïs side cannot paint accurately or comfortably, and accidents ' are likely to occur. The description of the adjustable staging of the present invention for use in the painting of `a ship’s side is only one example of its use, and does without departing from the spirit and scope' thereof as set forth in the appended claim. The invention described herein may be manu factured 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 se cured 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 not necessarily restrict the wider application of 20 base along thesides of said supporting structure, this invention. The staging can be used as a supporting structure for artisans working on large scenery props in a theatre, on billboards and .rotatable rods disposed diagonally along said ver tically vdisposed framework and engaging Ysaid turn-buckles, the turning of said rotatable rods .advertising signs; in fact, in any situation where changing the inclination of said vertically dis the surface to be worked upon is inclined to .the 25 posed supporting framework, means to rigidly vertical. When .some surfaces in a given work hold said rotatable diagonally disposed .rods to area are vertical and others are inclined 'to the vertical, the same staging can be used, thus di said vertically disposed structure, and .locking means to secure said framework after Ythe re minishing the number of stagings that have to be quired angle of inclination has been obtained. constructed by contractors for a given building 30 or other construction. -OLAV AUKLAND.
