CHARLES B. MGGALL'UIVI, 0F OAKLAND, CALIFORNIA'.`
GROUND FOR PLASTERING.
Application filed May 19, 1924. Serial No. 714,279.v
To c/JZZ whom t may concern:
Be it known that I, CHARLES B. MGGAL' Linu, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Grounds for Plastering, of which the following is a specification.
My invention relates to grounds employed in the art of plastering, and more particularly to removable grounds adapted t0 being width and rough edges7 in combination with the sawed grounds determine the parallelism and nominal thickness of the wall.
Therefore, having the above in view, an important object of my invention is to determine walls about an opening having parallel surfaces thereat, and of constant thickness, using the same studding above cited but eliminating the said grounds.
Another important object is to provide metallic grounds for determining the said parallel surfaces and thickness of the wall.
A further object is that the grounds of my invention shall be removable and adaptable for further use.
And a still further object is the provision of a ground in the form of a plate having means to quickly and accurately position the same, and making provision for the quick removal thereof after the plaster has set a little.
A. 4wall produced by the aid of my grounds has for its ultimate object, openings throughout the building such that the jamb, casing and other Woodwork can come from the mill as finished products and be immediately secured about. the opening without any cutting and tting because of said constant width and parallelism. y
A ground of my construction will admit correction in alignment of several openings as regards to the face of the walls in continuity, as a corridor for example.
For an applied illustrationofmy invention, drawingin combination.' with a door opening, and in which drawing: I
Figure'l is a front elevation ofagroun'd constructed vin accordance with theV invention. j
Figure 2 is aside View of it'applied tothe door-opening of va wall; some studding,lath-` I have shown it inthe accompanying' ing and plastered finished wall .is here y shown.
Figure 3 is p largedv scale, on the line of 2 and shows to advantage the-.ground in fixed` rela.- tion to the wall at the doorway.`
Figure 4 is a view similar rto a horizontal section, on an'en- ,Y
shows the ground as a flat plate, and Fig. 5
is also a similar viewvand introduced simply to show the present wood ground assemblyat such an opening.
Figure 6 is a fragmentary 'view of Fig; 1
showing an enlargement of one of the se' curing holes.
Adverting to the drawing and` figuresl thereof vthe numeral 7 indicates my ground and in Figs. 1 to 3 it is shown as-light plate rolled or otherwise formed` to an accurate form and width witlitrue andparallel outside faces 8. The width of the channeled ground is that of the nominal desiredstudding 9, plus the thickness of the wood lathl ing 10 and the nominalgthickne'ss of the-plaster 11. Of course, for"4 definite thickness-'of walls such as wide and'narrow ones,'I".will
have different grounds to vcorrespond with the desired thickness ofthe finishedwall.
The iianges 12 of my channeled ground v` serve as stiffening ribs to prevent the bodyA I from buckling or bending in usage, and the outside faces 8 present a broad guiding surface for floating the plaster or other coat- `4vrv ing 11 flush therewith. i
In Fig. 4 the ground 13 may be of fiber, plate steel or other suitable material, having accurately machined or otherwise formed parallel edges 14, the Awidth of thev ground being that of the desired thickness of the wall. 3
In Fig. 5 the ground'l is the common well-known wooden strip nailed for permanent securement to the studding 9 as at 16, and the plaster 11 is floated flush therewith.
In all the figures the width of the studdng is assumed to be the same, thus, if the nominal width is' 4, it might come from vWith my ground. and using the same studding and lathing thereeanbe'ouly the wvidth of Walldesired and that is the Width f. dfft'he ground, the thicknessbf 4the plaster being-the compensating element. "As pren vi'uslyfs't'ated,"withthe"aidof Iny'devi'c'e a given `Wall Willi-have aconstant'width with l "p'araliell"failles7 *enablingjmill- Work -for "fthe trimmings ofsuch-openings tobe 'atzeura'tely ositioned-With no hand trimming at all of 'iii-e 'vvall Vsurfaces' at' such-openings f "Thef'vmanner 'of positio'ning" and secur-r ing'my ground-inV place is unique, and herein residesv additional invention. `fof'weaehground,'a preferably round hole l?
