I This invention relates to plaster board by gravity against the teeth of the rack and supports and more particularly to a support to engage therein to prevent return movefor positioning and holding in position secment of the rack when elevated. When it is I tions of plaster board which are to be apdesired to lower the-rack, this latch may be 60 5 plied to the walls of a building. swung out of the way by hand and the rack An important object of the invention is to lowered. I I provide a device of this character which may Mounted upon the upper end of the rack be used for applying plaster board either to Is a platform 18 having upon its ,under surthe walls or ceiling of a building. 7 face a pair of depending flanges 19 between 65 A still further object of the invention is to Which the upper end of the rack extends and provide a device of this character having through which the bolt forming a pivot 20 vertically adjustable means for supporting a Is directed. The platforin, is adjustable plaster board which is to be placed upon the about the pivot so that it may be arranged ceiling, thus enabling the plaster board to be either vertically or horizontally, as shown in 70 placed upon the support while lowered and dotted and solid lines respectively in Figthen elevated to the proper position and l v held firmly in such position. Pivoted to the tubular housing adjacent A still further object of the invention is to h end there/(5f and swinging in a produce a device having means for holding plane at right angles to the direction of easy 7 th l t b d t b li d t th id movementof the base is the lever 21, one walls including a part for Vertically adjust- I end of which has rigidly mounted thereon a ing the sheet. hor zontal platform provided with a pro- These and other objects I attain by the j ctlon 23 upon Which the lower edge of a construction shown in the accompanying sheet of a plaster board is positioned. The 25 d i h i f th p r f 111 opposite end of the lever is formed with a --tration is shown a preferredembodiment of f r adle 24 and adjacent its pivot, the y i ti d h i leverus formed with ratchet teeth 25 for Figure 1 is a side elevation partially in coaction with a pawl 26 pivoted to the casing section of a plaster board support construct- 12 for holding this lever in adjusted posied'in accordance with my invention, the'ponS- sitions of the platforms being illustrated in I In the use of the device for applying solid dotted lines, a portion of the standard plaster board to ceilings, the rack is lowered and housing being broken away to show the to its fullest extent and a sheet of plaster engagement of the gear and rack; and board placed upon the platform 18, the plat- Figure 2 is an elevation at right angles to form at this time, of course, being horizonthat shown in Figure 1 showing the manner tally disposed.

The leis arranged for vertical reciprocation a rack ver is operated to raise the lower end of the bar 13. Mounted upon the side of the tubusheet to the proper height and the entire delar standard is a housing 14 in which is rovice moved into engagement with the wall tatably mounted a crank shaft 15 having where it will support the sheet until it is mounted thereon within the housing a gear properly secured. 16, the teeth of which project through an It will, of course, be obvious that the conopening formed in the tubular standard and struction hereinbefore set forth is capable engage with the rack. Pivoted to this housof a considerable range of change and modiing 14 is a latch 17 normally adapted to rest fication without. materially departing from the spirit of my invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed.
I claim In a machine for holding laster board while securing the same to ceilings or walls, a vertical tubular standard, a rack Within the standard, means for vertically shifting the rack, means for holding the rack in vertically adjusted positions and a pivoted platform carried by the upper end of the rack and swingable to horizontal or vertical positions, a lever pivoted intermediate its ends to the standard adjacent the lower end thereof, means for holdin the lever in adjusted positions and a plat orm carried by one end of the lever, said platform having a stop for engaging a sheet of plaster board, the first named platform partially overlying the last named platform when in horizontal position. 2o
