IMPROVIWENT IN SKATE-SHARPENER To all whom 'it may conce/rn:
Beit known that I, J OBN F. CAMERON, of Brook- 1yn, -in the county of Kings, and State vof .N ew York,
have invented a new and improved Skate-Sharpener;
and I do hereby declare that the following is aA full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side view of my improved skatefsharpener.
Figure 2 is a vertical transverse section of the same.
Similar letters of reference indicate corresponding Parisi This invention relates to a new instrument for resharpening or reshaping the running edges of skateirons, and consists of a grooved instrument, which retains the grinding-tool at the bottom of the groove, so that the iron is guided between the two flanges, to

can be fitted from the side; the ends of the tool and the recess being so shaped that the said' tool cannot drop out nor be inserted otherwise than from the side.
To one side of the rib a is pivoted, by a pin, b, a plate, O, which, when turned to cover the rib, forms another flange on the side of the tool, as shown in fig. 2, the tool being thus held at the bottom of a groove, of which the platesA 0 are the sides.
The said plates A G form guides for the skate-iron while the same is being sharpened, in order to let the grinding or sharpening be true.
The tool B is a file, or made of other material, and may be reversible for different kinds of work.
When the plate O is swung aside, as ing. 1, the tool can be removed or reversed.
In the upper part ofthe rib a, is a polygonal recess or indentation, c, for receiving the polygonal head of a gixnlet, D, as shown in iig. 2, by means of which gimlet the heel may be bored for the reception' of the skatepin.
I claim as new, and desire to secure by Letters Patent.-
The skate-Sharpener, consisting of"` the plate A a,
