JAMES E. EMERSON, V01a TRENTON, NEW JERSELANDW'ILMAN'S. WINSOR;
` or THUSVILLE, PENNSYLVANIA,
Letters .Patent lfm-74,523, yelated February 1.48, 1868.
. IMPROVEMENT IN SAWS.
TO ALL WHOM .IT MAY CONCERN:
' Beit known that we, JAMES E. EMERSQN, of Trentoinin Ythe county of Mercer, arid State of New, Jersey,
and WILLIAM S WINSOR, of Titusville, infthecounty of Crawford, `and State of Pennsylvania, bave'invented new and useful Improvement in P1ailing-Saws; and that' the following is a. full, cler, and exact description o f thesame, reference being1k had to the accompanying drawings, Emaking apart of thisspeciiiclttiom, in`which\ Figure 1 represents a portion of a circuler saw constructed after our general plan. v Figures 2 and` represent views fronfopposite sides of the planing-tool, 'and on an, enlarged" scale frein Ithe same, as shown in place in the saw in iig. 1, l
Figures 4 and 'yrefireset cross-sections through the jsaw-plate, and shovvfmorev particularly 'the `projection of the planing-tool br instrument from the faceof theiplate.V Y
'Simi-lar letters of reference, where vthey occur in-the sepa-rate ig'ures, denote like parts of the saw in allot thedrawings. e f Y l I Our invention; consists in combining with a. saw and lplnner'ou one' plate, a support, guide, or gauge, at or Our inventionfurther consist'sfin inserting'end holding a. planing-cutteryina saw-plate, by means of-n tapered opening in the plate, and'a'tongue or tongues on one, and a groove orgrooves4 in the other. i
To enable others skilled in the art to make and use 'our invention, we will proceedl to describe the same near the pla.ning-cutters, to prevent them from running into or taking too rank ay hold of the wood; and j vwith reference to the drawings. y
4 A represents a sa-w-plate,"ronwhich removable and'- replaceable teeth B are arranged. 'This saw-plate-is of' nearly4 uniform thickness throughoutand'has planing-jcutters-C- connected `With`it, near its lsawing-edge. The planingcutters C, as shown .in figs. 2 and 3, are rights and lei'ts, that is, their cutting-,edges are alltel'. nately on one side and then ontheother sid-eroi' the saw; orfii' not alternatelyl so, thenythe setsare so' arranged. We preferto make these planrxgcutters C removable, and to'secure them tothe plate by an opening D, having a tapering 'form and bevelled edges,wh icl1 letterVA *takeintoV grooves' formed in the edgesof the planing-critters.` The-cutters'may have a holethrough them, ntohvvhich a steel pin is inserted, and by tapping upon the pin withA a hammer or otherwise, the lcutter may be set back and tightenedin its seat, or started forward-to loosen it, as may be desired. To'pre'ven-t the cutters from taking too rank a hold ofthe timber, or from biting into the wood, a projection, a, is formed on leach'cutter,lw'hicl1 servesas a gauge or guide toprevent the cuttng-edgo from taking into the timber. The rear portion of the cutter, behind its cutting-edge, and' on that side of it,A serves as a. guide or gauge on that'side, so that vvhilst the saw-teeth arecutting the kerf', the cutters C are planing the timber o'n both sides of the ker-f. That part of the cutting-edge of theplaning-knives most remote' from the perimeter, as vseenat-c,`is bevelled ofi" seas not to cut atrthat corner, .thetioing of which would clog the cutter. I l Y, i. ,n l
These planing-cutters are.` equally applieabl'eto reciprocblting asl to circular saws-aud forro their own support against biting intoor taking too rank1' a hold` "of the wfood. A' y Y l Having thus' fully described our 'inventiomjvhat we claim ltherein as nem-aud desire to secure by Letters Patent, is-j t Y v In combination withsawing-teethand `p laning-cutters separately attached to and removable on the same saw-plate, Athe support, gude,.or. gauge on the planing-cutters', to prevent themyfrom 'running into or taking too rank a hold of ,the wood, substantially as. described.
