SCREED HOLDER.

: Application filed December 10, 1923'. Serial No. 679,583.

vide a screed holder of simpler and cheaper construction than any heretofore made, but which will possess in full measure, all the qualifications essential for efficient service.

lVith this general object in view, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be readily understood,'reference is to be had to the ac- ..companying drawing, in which:

Figure 1 is a perspective view of a section of concrete flooring and of a series of screed holders and a section of'a screed in anchored relation to one holder and in aline :ment with the others.

Figure 2 is an enlarged vertical section on the line II-II of Figure 1.

Figure 3 is a perspective view of one of the holders as completed and'ready for application to a soft concrete floor.

Figure l is a perspective view of aholder with the nailing or arm projecting outwardly in opposite directions and the body portion braced at the junction therewith of said arms.

Figure 5 is a section onthe line VV of Figure l.

Figure 6 is a detail perspective view of the brace of Figures 1- and 5.

Figure 7 is a perspective view of a holder having resistance or bracing parts at the junction of the arms and body, of modified form as regards the brace of the preceding construction.

Figure 8 is a perspective view of a screed holder of flat or sheet metal, but provided with resistance or bracing features corre sponding in mechanical function to those of Figures 4 and 7.

Figure 9 is a perspective view of a holder of the same type as the preceding figures, but adapted to receive and anchor a wider screed.

Figure 10 is a side elevation of a modified form of the screed disclosed by Figures 9 and 10.

Referring now to the drawing in detail,

it will be noted that Figures 1 to 7 inclusive,

disclose holders made of wire as contrasted with the sheet metal holders of'the remain- 1ng figures, but that in all cases the body portion 1 isof V-shape or double V-shape where screeds of considerable or unusual width are to be used. In all cases however, the extremities of the body portion terminate in arms adapted to occupy a horizontal in place.

In the simplest form of the invention as exemplified b Figures 1 to 3 inclusive, the

arms'2 exten inwardly from the respective ends of the-body portion, and lie horizontally in overlapped relation, and in all of the Wire-type forms, the said arms terminate in nailing eyes or loops 3. I

In Figures 4 and ,5, the arms extend hori :zontally outward from the respective ends of .the body, and a brace 14 extends between said ends to brace the body at the junction withthe arms. The brace is roduced from a strip of fiat metal longitu inally split at' its ends and folded in line with the splits to inverted V-form in. cross section. The split ends are each bowed as at 5 to proe 1 position until the screeds are to'be secured vide downwardly-converging loops and parallel end extremities 6. To apply the brace the extremities are spread apart to-permit the brace to be'slipped down until arrested by the upper or end portions of the body. The extremities are then pressed together so as to underlie the arms 2 and thus close the loops snugly upon the body. The brace thus positioned constitutes an abutment for preventing movement or distortion of the body when the arms are bent upward preliminar to the reception of the screed.

In Flgure 7, the material is bent to provide transverse portions or resistance abutments 7 joining the body portion and arms, so that the latter can be bent upward without distortion of the body portion, as described with respect to brace 4.

In Figures 8 and 9, the sides of the body are flanged or channelled, as at 8, to not only more effectually resist lateral movement of the body when the arms 2 are bent to upright position, but to stiffen the body so that its sides shall offer resistance at the bending oints against distortion of the body during such bending operation.

The arms in said figures and in Figure 10, are provided with nail holes 9, for receiving the nails 10 used to secure the screed to andbetween the arms, the loops3. being the equivalent in thewire constructions of said holes.

In Figure 10, the strip of metal of the body is preferably of heavier gaugethan in Figures 8 and 9, and the sides are disposed in edgewise relation, the metal at the apex of the body being distorted laterally at. 11.

in substantially the same manner shown at the apex. of the body portion of Figure 8.

The sidesof the-body portion .at the junction with the arms 2, are twisted at'12, to

permit the arms to lie in overlapping relation as shown, until ready for the reception of thescreed.

In all casesthe holders are forceddown.

into the concrete .(as shown atthe left-hand end ofFigure, 1), after ithasset sufficiently topermitworkmen to walk upon .plankslaid upon it, the holders being arranged in as ma ny parallellines as there are screeds to be used),

The. planksare then removed and after the concrete has hardened, workmen can Walk upon it or run wheel barrows over it.

Without interference by the holders, as the arms of the latter lie flatlyuponthe sure ceof he onc ete.

VVhenready to lay ajfloor upon the-con cr.ete,,the arms 2 are bent upward as inclicatedinlFignre land by dotted lines in other, figures, and the screeds S are placed upon-the floor betweensuch arms as shown byll jigurel, and are secured in position by nails: driventhrough the loops 3 or, holes 9, a s the case may be. The flooring, not

show- 1,021.11 then be nailed to the. .screeds.

From thealbove description it wil'lbe apparent that 'Ijhave produced a device ofthe character described which possesses all the features of advantage set forth as desiraportion, said: arms being. provided with.

openings, and adapted to be'bent at their junction with the body, to substantially verticalpositions; the holderlhaving means constituting. resistance. points at. the junction of the arms with the body, to permit the arms to the bent without. distortion: of the body portion. a

2. A metal screed .holder o;f, .s'keleton form bent to form a depending body having downwardlyronverging sides and normally horizontal arms attheupper ends of the sides and integrally; formed therewith and provided with nail-receiving openings.

3. A metal screed holder of skeleton form bent toi'orm a depending body having downwardlymonverging sides and normallyhorizontal arms v at the upper ends of the sides and integrally, fonnedltherewiththe arms projecting ;in opposite directions from the respective sides fifliheqbody andfhaving nail-receiving holes.

4:. A metal screed holder. bent to, rela-v tively W-shape toprovide adriving point for use in inserting the screed;inthec011,-- crete, and normally horizontal arms at the opposite ends of saidWisha-pe extending inopposite directions.

In witness whereof I. hereunto, afiix my signature.
