4, 1925. O. FYHRIE CURB FINISHING TOOL Filed April 24, 1923 Patented Aug. 4, 1925 OLE FYHRIE, OF RACINE, WISCONSIN.

CURB-FINISHING TOOL.

Application filed April 24, 1923.

T 0 all whom it may concern Be it known that I, OLE FYHRIE, a citizen of the United States, and resident of Racine, in the county of Racine and State of lVisconsin, have invented certain new and useful Improvements in Curb-Finishing Tools; and I do hereby declare that the following is a full, clear, and exact description thereof.

'li his invention relates to curb finishing too s.

In finishing curbs it has been the usual practice to pour the horizontal portion and allow it to harden, and, thereafter, to pour the vertical portion. After these two portions have set, a finishing coat of cement is applied, and the usual practice has been to use a form, which is held in position by an operator kneeling beside the curb, and is pushed along to shape the finishing coat of cement to the exact gradually curved contour which is so much desired in this type of work. v

This process has been extremely slow and the tools have been so constructed that a right and a left hand tool was needed or else only one direction of operation was permitted. In addition to this it necessitated the operators holding it in place with both hands while he knelt beside the curb, necessarily resulting in extremely slow finishing.

This invention is designed to overcome the above noted defects, and objects of this invention are to provide a curb finishing tool which is adapted to be operated in either direction and which may be pushed along by one or more operators while they walk along the portion of the street adjacent the curb, thus providing a tool which may be operated at maximum speed and with the least possible effort to produce a perfectly finished curb.

Further objects of this invention are to provide a curb finishing tool in which elongated handles are provided and are adjustably secured to the tool so that one of the handles may be employed to advance the tool while the other may be employed, and if desired by a separate operator, to hold the tool in position by furnishing the necessary lateral pressure.

An embodiment of the invention is shown in the accompanying drawing, in which:

Figure 1 is a sectional view through the curb showing the tool in position and partly in section.

Serial No. 634,230.

Figure 2 is a plan view of the structure shown in Figure 1.

In forming a curb a pair of side boards 1 and 2 are temporarily positioned and the horizontal and vertical portions 3 and fl: respectlvely are successively poured and allowed to harden; thereafter, finishing cement is positioned over the roughly formed curb and a finishing tool is slid thereover.

The tool comprises a heavy sheet metal plate 5 having any desired contour, such as shown in Figure l, and comprises a horizontal portion, an upwardly extending portlon, and a shorter horizontal top portion. The marginal edges of this tool are upturned as indicated at 6 so that the tool may freely be pushed in either direction, the curved marginal edges easily riding over and forcing down the finishing cement. It will be noted that the upturned edge at each margin braces the structure materially, but to furnish a further bracing action,.a pair of brace members 7 are provided and are riveted to spaced portions of the device as may be seen from Figure 2.

A series of rollers 8 are carried by suitable supports riveted to the upper side of the apparatus and are adapted to project through apertures 9 formed in the body portion 5. These rollers are so positioned that they travel upon the upper edges of the boards 1 and 2 as may be seen from Figure 1.

A substantially centrally located casting 10 conforming to the curved contour of the body portion, as may be seen from Figure 1, is riveted or otherwise secured in posit-ion and, as shown, approximately centrally of the body portion. This casting carries an upwardly projecting pin 11 upon which are pivoted the hubs 12 and 13 of

elongated handles

14 and 15. These handles may conveniently be formed of wood and riveted to extensions projecting from the hubs, as shown.

In using the apparatus, one operator grasps the handle 15 and walking along the side of the curb pushes the tool at a substantially uniform and relatively rapid rate along the curb, the other operator presses the handle 14 inwardly, thereby holding the tool in position and maintaining the requisite pressure. It is to be noted that both handles press downwardly and thereby secure the necessary downward pressure for the tool.

It is to be particularly noted that the tool is so constructed that an operator may wall: along the street adjacent the curb and may rapidly finish the curb. There is no danger of the tool movingout of position as it is held inwardly by the handle 14:.

It will thus be seen that a curb. finishing tool has been provided which may be 0p erated in an extremely simple manner and whibch will produce a well finished smooth cur It will further be seen that a large amount of friction is avoided by providing the rollers 8 and that, therefore, a minimum of effort is required to operate the tool.

It will further be seen that the tool may be operated in either direction and is, therefore, very effective in ordinary street work.

I claim:

1. A curb finishing toolcomprising a blade having horizontal and vertical faces and upturned transverse marginal edges, and a pair of elongated handles pivotally secured to the blade substantially centrally thereof, whereby the blademay be pushed longitudinally in either direction and forced transversely and downwardly simultaneously with the pushing operation.

2. A' curb finishing tool comprising a blade having horizontal and vertical facesand upturned transverse marginal edges, and a pair of elongated handles pivotally secured to the blade substantially centrally thereof, said handles being inclined upwardly and outwardly to permit free manipulationby two operators, whereby the blade maybe pushed longitudinally in either direction and forced transversely and downwardly sin1ultaneously with the pushing operation.

3. A curb finishing tool comprising a blade having horizontal and vertical faces and upturned transverse marginal edges, a stud carried by the blade substantially centrally thereof, and a pair of elongated handles pivotally mountedon said stud whereby the blade may be pushed longitudinally in either direction and forced transversely and down-v wardly simultaneously with the pushing op: eration.

4. A curb finishing tool comprising ablade having horizontal and vertical; faces and;

upturned transverse marginal edges, and, a pair of elongated handles pivotally secured to the blade substantially centrally thereof, both of said handles being inclined u,pwardly, whereby downward pressure may be exerted upon the blade, one of said handles being adapted to extend longitudinally of the blade in either direction for pushing the same, and the other of said handles be ing adapted for positioning at various; angles to the first mentioned handle, where by the longitudinal and transverse oomponentsof the force transmitted through; said. last mentioned handle maybe varied,

In testimony that I claim the fQr going I have hereunto set my hand at Racine i nl the.-
