CURB-SHAPING TOOL.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed October 10, 1910. Serial No. 586,362.

To all whom it may concern:

Be it known that I Earn. Onsos a citizen of the United States, residing at .toekford.

in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in UnrlrShaping Tools; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art, to which it appcrtains to make and use the same.

This invention relates to shaping tools and is particularly designed for use in connection with shaping the top of cement curbing and also rounding 0d the outer and inner edge of'same.

I am aware that various forms of smoothingand shaping tools are in' use, and I do not claim the broad idea ot a smoothing tool of this character. I

In smoothing or shaping tools as heretofore constructed, however, provision has not beenmade, so far as I am aware, for shaping or rounding oil both the inner and outer u )per edges as Well as smoothing oil the top 0 a cement curbing, in one operation, and the ob ect of my present invention is to prowide a tool for accomplishing this end.

A furtherfeaturc of the invention is that erence is had to the accompanying drawings, illustratlng preferred and practical em- 'bodimentof the same, 1n which drawings like characters designate the same parts m the several views and in wl'nch:

Figure l is a perspective view of my 1m:

'proved tool; Fig. 2 is a longitudinal section through the same; and, Fig. 3 is a cross sectional view.

1 designates the top of the tool which has an underneath smoothing-surface 2, turned upwardly at ,both ends, as at 3, in a flaring curve stantially as described.

4. a handle for the tool.

The inside smoothing portion consists of the downwardly depending wall 5, having a curved smoothing surface (3, and on the opposite side of the tool, the same is provided with a second, depending wall 7, which inclines downwardly and outwardly and has a smoothing surface S of greater area and more rounded contour than the smoothing surface (5.

By the foregoing construction, it will be observed that a very ncatly'finishcd curbing can be produced in one operation by moving the tool bac c and forth over the cement before final setting, and the upwardly curved flaring ends 3, prevent the front and rear edges of the tool from mutilating the top surface.

Having thus described a practical embodiment of the invention, the particular features of novelty will now be pointed out more succinctly in the following claims.

I-claim 1. In a curb shaping tool, a top plate provided with a handle and an underneath smoothing surface and having depending side walls formed integral therewith and provided with smoothing surfaces on their inside faces, said top plate and depending walls terminating at their forward and rearward edges in upwardly flaring curved lips, substantially as described.

2. A curb shaping tool comprising a top plate provided with a handle and an underneath smoothing surface, and further provided with depending side walls having smoothing surfaces, the outer of said side walls being deeper than the inner of said walls and inclining downwardly and outwardly, said top plate and said sidewalls merging at their forward and rearward edges in upwardly flaring curved lips, sub- In testimony whereof,I aifix my signature, in presence of two witnesses.
