DAR/BIE.

Application led August 22, 1925. Serial No. 51,776.

This invention relates to a darbie for use by plasterers, one of the objects being to provide a structure having a facing or edge strip so mounted that it becomes impossible for the attaching screws to work loose and nick or otherwise mar the trowel.

It is well known to those skilled in the art that if a darbie is provided with a metal st rip along the side edge thereof the fastening means, in the form of screws, nails or the like, tend to work loose when the wood of the darbie becomes saturated with moisture. Consequently in the use of a trowel the same is often brought into contact with these projecting fastening means and becomes 'nicked or otherwise mutilated so that it will not produce a smooth surface when used 1n applying plaster to a wall or ceiling.

It is an objectof the present invention to provide a darbie in which it becomes 1mpossible for the fastening means of the edging strips to work loose and produce the objectionable results mentioned. A

IVith the foregoing and other obJects in view which will appear as the description.

proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In th-e accompanying drawings the-pre-v ferred form of the invention has been shown.

In said drawings,

Figure 1 is a perspective view of a. darbie having the present improvements combined therewith.

Figure 2 is an edge View of a portion thereof on an enlarged scale.

Figure 3 is a section on line 3 3 Figure 2;

Figure 4t is a similar view showing the edging strip prior to being bent to its ultimate position after being applied to the darbie.

Referring to the figures by characters of.

reference 1 designates the wooden body of the darbie provided, as usual, with a handle 2 and a longitudinal iin 3. As heretofore explained each longitudinal edgeof the darbie is ordinarily provided vwith an edging strip of metal held to the wooden body by screws or nails the heads ofwhich are countersunk into the strip so as to leave a smooth surface.v In the present instance a metal edging strip 4 is provided along each side edge of the body 1 and has openings 5 for the reception of the heads of screw v6 or like fasteningmeans extending into the body V1. Strip 5 is of a width equal to twice the thickness of the body 1 and after this strip has been fastened in place one-'half thereof is folded onto the other half so as to erta over the heads of the fastening devices as shown in Figure 3. Thus it will be seen that it becomes impossible for the fastening means to work loose and, consequently, the strips present at all times smooth surfaces free of projections. A trowel can therefore be slid along these strips while removing plaster from the darbiefand there will be no danger at any time of the edgel of the trowel being f nicked as would be the case should the fastening means work loose.

What is claimedis:

The Combination with, the body 'of a. dattie,

of a metal strip fold-ed along the longitudinal center and having the folds close together, and fastening. meansextending through the inner fold and into the body of the darbie, said fastening means having a head the outer face of which is Hush with the outer surface of the inner fold, the outer fo-ld constituting a guard to hold the fastening means against loosening and to prevent contact of a trowel or the like withthe head of the fastening means while the darbie is in use, the said metal strip', when folded,l having its opposed edge portion flush with the opposed faces of the darbie.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature.

WILLIAM T. MARTIN.
