UNITED STATES VERNER G. H. GROTHE, OF ST. PAUL, MINNESOTA.
SCREED SUPPORT.
Application led May 21, 1925.
My invention relates to screed supports used in concrete construction and the object is to provide a simple, eiiicient and easii ly adjusted device of said kind.
8 ln 'the accompanying drawing:
Fig. l is a floor plan or top view of a corner of a building under construction with a series of my devices in operative position.
Fig. Q is a top view of the device itself.
Fig. is an enlarged section on the line .l-3 in Fig. 1.
Fig. 'at is a bottom view of the device itself on the same scale as in Figs. 2 and 3.
Fig. 5 is a section of the device as on line 5-5 in Fig. 3.
Fig. G is a side view and Fig. 7 is a bottom View of the foot piece of the device in modified form.
Referring to the drawing by reference numerals, l0 designates the outer walls of building in which a concrete floor 11 is being formed upon a suitable temporary board structure or mold 12. 13 are the usual screed or wooden strips placed upon the concrete and having the Wooden licor 14;
nailed upon them.
ln the use of my devices each of the fcreeds 13 is placed in a series of sheet metal clips 15 each of which has a screw 1G securing it to the top end of a post comprising two telescoped members 17 and 18.
llhe lower member 18 has a base plate 19 with a central wood screw 2O to engage in the mold 12, or, as in the modifications Figs. 6 and 7, a few pointed pegs 21 may take the place of screw 20.
The post member 18 has at one side a rack 22 slidable in a channel or groove 23 in the post member 17. The latter channel has a lateral aperture 24 through which is directed the angular end portion 25 of a leaf spring 26 which has its upper end secured to the section 17 as at 27 in Fig. 3. ln the use of the device a suitable number Serial No. 31,962.
of rows of these supporting devices are secured upon the mold 12 to hold the posts with required firmness in their places, the spring catches are then moved to such points of the racks that the clips 15 will support the screeds 13 with their tops in a true plane, either level or sloping as may be desired. The concrete is then poured as thick as wanted and smoothed olf so that its top surface is about level with the under side of the clips 13 (see Fig. It is well known that during the hardening of the concrete it settles more or less unevenly and its tcp surface is therefore uneven. Thus when screeds are to be laid directly on such surface they must be trimmed off or shimmed up to conform to the uneven top of the concrete in order that the top of the screeds may be absolutely level. This requires a large amount 'of skillful and costly work but never insures a perfect plane of screeds on which to nail the floor boards. Any slight unevenness causes sagging or bulging of the floor boards and the result is a floor which is very squeaky when in use. It is obvious that my devices when properly gauged and imbedded in the concrete hold the screeds in a true plane.
That l claim is:
A screed support comprising a base with an integral vertically disposed post, an upper tubular member slidable on said post, the post having a toothed rack and rack engaging means on the tubular member adapt ed to be engaged with the rack at any de sired elevation thereon and a U-shaped clip on the upper end of the tubular member for guidingly supporting a screed, said rack engaging means comprising a spring mein` ber fixed on the tubular member and extending downwardly thence inwardly horizontally to engage the rack.
In testimony whereof I aliiX my signature.
