IMPRCVEMENT lill GUFPER-HEADSv 1E' OR WOOD-PLANING MACHINES.
"dille dgrhule marsh tt iii. tlgeetdters @aient-mit mating yid .t tige sama TO ALL WHCM ITMAY COCERN:
Be it known that I, THOMAS TOSTEVIN, of Council Bluffs, in the county of Pottawatomie, and State of Iowa, have invented a newand useful Improvement in Platters; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to makeand use the saine, reference being had to the accompanying drawings, forming part of this speciiication.
.Figure 1 is a side view of my improved planer-head and knives.
Figure 2 is a cross-section of the same.
.Figure 3 is an enlarged detail cross-setion of the cap.
Figure 4 is an enlarged detail cross-section ofthe knife or cutter.
. Similar letters of reference indicate corresponding parts.
My invention has for its object to furnish an improvement .in the construction of the cutters Vand caps of planer-heads, whereby the first' cost will be diminished, less grinding will be necessary to keep the cutters in order, and the eiliciency oft-he planers will be increased;`- and iteonsists in the construction of the knives and caps' as Vhereinafter more fully described. I
A is the 'cutterhead,-which I prefer to make of Wrought iron', and which is constructed, attached to the machine, and driven in the ordinary manner. B are the k-nives, which'are made of sheet steel, and much thin# ner than the ordinary planer-knives. The knives B are made with an outwardly-projecting flange upon their rear edges, as shown in figs. 2 and C are the caps, which are made in substantially the form shown in figs. 1, 2, and 3. The caps C'are made with a series of longitudinal grooves in their under sides, into which the iiang'e of the .cutters B tits. This enables the knives or cutters tobe moved forward, as they are worn or ground away, until they are used up. The under vside of the capstC, in the rear of the longitudinalv grooves, should project about the thickness of the knives or cutters B, -so that it may rest against the cutter-head A, in the rear of the said knives or cutters. i v f The projecting part of the caps C should be slightly hevelled ofi', or inclined towards the forward edge of said cutters, as'shownin figs'. 2 and 3. The forward part of the caps should be made in about the form shown in ig. 3, and its forward edge should project a little beyond the vplane of its inner side, soV that it may press more 'firmly against the forward part of the saidcutter's B. The knives B and caps C are adjustably secured to the cutter-headA by set-screws fi), which pass in through slots or notches in the rear parts ofthe caps C, and screw into the cutter-head A. This enables the caps C to be moved forward and back, or adjustedas may be desired. By this construction the cutters are held firmly in place, and in such -a manner as to guard against vtheir liability toA be broken, the caps pressing against themthroughout their entire length, and should a notch be formed in the cutters, by their striking against a nail in theboard being planed, they may still be made to plane the board smoothly without being ground, vby moving one of the cutters longitudinally the width of the said notch.
I claim as new, and. desire 'to secureby Letters Patent- The cutters B, having an outwardly-projecting flange upon their rear edges, and the caps C, provided with a series of parallel longitudinal grooves in their under sides, constructed to operate substantially as described.
