` Specicationjof Letters` latent 1\`|'o.` 12,787, dated May 1, `185.15.

` 1i y `Be `it known `that I, GEORGE of Lowell, county of `l\/Iiddlese1f`and' State of Massachusetts, `have "invented la*v` new fand" `useful iron plane-stocland a new method `of attaching the i cuttin`g-ironsf to the `stocks "to` be used by carpenters and woodworkmen generally to be used` and adoptedfinstead `of the old woodplane, molding and other "tools which have been `heretofore used; and

" i `I hereby declare that thefollowing is a full,

clear, and exact description of the manner of making and using thesame, rwhen taken in connection with the accompanying draw- `ings `and letters of 'reference markedthereon, in Which` i i n Figure l, denotes aperspective view.` Fig. a longitudinal, and vertical `Section l through the center of the same.

W`The nature of my invention consists in i constructing the mainbody` of planes, molding tools, `;&c., of metall, `which being very thin, presents little or `no impediment to the n "shavings passingout as `they are cut fromV the wood, `using an iron or wood handle attachedto these planes.,` By means jofthe lowerportion ofthe plane `stock thusmade,

`the hand of the operator is very near the face of the planewhenit is used and conse quently equally near, the face of the stock which is" being dressed: And my invention i furtherconsists insecurng the cutting irons i tothe iron or other plane or tool stock, by means of a single screw (insteadof the old ship) which screw secures both the cap and the cutting iron together, `and both of them y `tothe iron toolorl planestoclnand by; forming a lip in the back part` of the throat so asto fill it and thus give a smooth even sur- "facefto the face ofthe plane, all as hereafter "described i i "To enable others skilled in the art to make and `use myinvention, I will proceed to describe its construction and g operation;

I Vconstruct y a` i malleable iron plane i stock seen at AA, of the drawings, to

this stock I` attachia handle whichimay be fmadeof iron or wood as seen at B, and

this "is attached to the `plane stock "by y the screw Hb Onxthe upper side of theplane y `stock Iiform a Iprojection as seen at C at each side ofwhich is formed, a projection `as seen at Gr, 4so asto receive the cutting iron,

which differs from all other plane irons in being constructed and attached to the plane as fol1ows,both the cutting iron D and the cap E being secured to each other and to the plane st ock Gr one screw as seen at F which iseffected by `forming an oblong slot in the cutting iron about one inch long, and wide enough to `receive the screw, and rthrough the purpose vof receiving this screw, and also of allowing the cutting iron to be moved down as itwears in using, in the throat of the plane immediately back of the cutting iron, I form alip as seen at I, so as to fill the recess caused by the bevel on the edge of the plane iron in the ordinary plane, thereby preventing its catching, and illing with portions of wood, as it is used, and presenting a smooth surfaceV to the wood.

` At J can be seen the start which is for the n purpose of starting the iron back or upwards when desired` To use my invention of improved plane I first1 set the proper edge upon the cutting iron, then place this iron into its position in the planestock then properly place the cap in its position upon the cutting iron,

and then place the screw F in its position and turn it to a bearing, by a screw driver or otherwise and the plane is ready for use. This same description will answer for the single cutting iron, excepting the description of the cap, the use of molding tools being similar to the previous description for planes. v

Havingthus described my invention what I claim as my invention and wish to secure by Letters Patent, is-

The metal plane stocks having a formai tion of a lip I in the back part of its throat so as to ll the recess which would otherwise be below the level of the cutting irons soas "to present a continuous smooth surface to the plane excepting the edge of the cutting irons and throat forward of them, for the outward passage of the shavings essentially n tlhe manner and for the purposes set ort GEO. E. DAVIS.
