Specification of Letters Patent No. i296, dated July 29, 1,837.

' curacy and- .uniformity as well as more expedition and Veconomy lto the work ofthe house-carpenter and joiner.

To ambie Others Sinne-d in them of trade of the Vcarpenter iand joiner to make andV use my said invention ,or machina .I will proceed to 'describe its construction and operation,fby means of description Words and drawings, with lletters and' figures indieating references, Aand the connection betweensaid words andk drawings, as follows, to wit:

The letters V, V, V, V, V, V, denote the general frame work ofthe machine, which sustains the other lmovable, and xed parts of the machinery.

A, and B, are drums coupled by belts with other parts ofthe gearing and driving the machine.

C C O C are pulleys or wheels fixed iirmly on the ends lof the axes of the .solid fluted rollers, which carry the'board, plank, r-or other stuit through ithe machina to be worked.

-D ,D cl, D d, D d, areset-sof solid iiuted 4rollers,two in a set, one right over the other, the upper one D;. and the under one d. These rollers, which maybe termed speed-rollers, hold .the board, or othery piece of wood to be worked, firmly between them, and as they turn on their axes in contrary directions, that is, toward each other, they carry the said board, -or other wood, from which'themolding, or sash, or other thing, is to be made, through the machine. `The upper roller D, in eash set, is movable up and down, to accommodate the thickness of the board &c. from which the molding &c. is to be out, except the first set, vofwhich the upper one D, is xed, and the lower one, cl, is movable. E,E, E, E, mark a'frame in which two of the upper speed rollers D', D', are fixed, and which frame may be moved up and down, and gaged to suit the thickness of the molding required. yF, F, F,

denote the bed on and along which `the board, or other piece of wood to be' worked upon, passes; the outer or left hand portion "Ff, F", F', of said bed, through its wholey ,length,"being rabbeted down to lac'comn'iodate thatpart of the board &c. which is not included in the widtlrof the molding, sash, or other thing to be made. G, G, denote an iron plate -u-nder which the board &c. passes.

This platecan'be raised, or loweped, to accommodate thethiCkneSs of the board &c.

from whichithe molding &c. 'is to-be cut.

Theraising and lowering ofvthis plate kare etfectedby -endless screws I I cut on the ends of the shaft I, which revolves onits own axis, in the upright metal plates H, H, and --which screws mesh with thepinions 71s 7c, which are cut, or'uted, orv grooved, to correspond `with said screws; these pinions are fixed to the heads of screws passing throughtheiplateG, Grand' resting on an immovable base.

Underthe plate GWG, is a hollow cylinder of iron {Z,`Fig. 3, about 12 inches in diameter,turning 'by-means of a pulley ,e on its axis, vand to,` which are fixed knives from 2 to 6 fin,number, having an .oblique edgelike a rabbet-plane, 'for dressing: ott theunder-ace, .or-side, of thatfpart ofthe board en theupper sirde'ofl which the molding '&c.is,to` be cut. rlhe letter m, denotes imV standard with tu@ Smallru'lleys 01 wheels, marked/a, n, which -turnV on their own axes, are fixed to the; lower end of the Standardand assist to hold down the Iboard & c. closely upon thebe'd. Misawheel with cutters, or knives,from 2 t0 6in number, having` their edgesof the shape of the required molding lac.' They are attachedtoV the side-oitI the wheel by means of screws and nuts,and, presenting their edges to the board yas it is` driven alongl the bed under them, they cut the molding &c. N is a slide furnished -w-ith .animmovable pin at .the lower end, on which ypin is put a metal roller of the shape of the required molding &c. The slideit-self is raised or lowered to suit the 1thickness of the molding and secured toits gage by screws. O is a plane stock with a p aning-iron Vhaving its edge of the form of the molding &c. P is a slide to which the plane-stock O is fastened. q, g, g, g, denote ways in which the slide P moves horizontally. R is a :t'rameV having ways for the other ways g, g, g, g, with the slide P, to moveup and down in. S denotes a crank-pulley having attached to it a sweep T, which moves the slide P, and which sweep is secured to the crank-pulley by the pin and slide o. This part of the apparatus regulates the action of the plane O as the latter descends upon the molding and rises from it, and gives to said plane its length of stroke. The dotted irregular curve line marked fw, w, w, indicates a projection, on

the back side of the crank pulley, which projection operatesv as a cam and acts upon a projection from the lever y, the use of which lever is to press down the plane O for the purpose of dressing off the molding.

The letter X denotes' a circular, or buzz saw, which is movable laterally on its journal a, and may be there gaged to the width of the molding, &c. which it cuts from the board as it is driven along the bed.'

The letter Z), denotes a short and gentle elevation, or inclined plane, rising from the inner part of the bed along which the molding &c runs, and raising the molding &c.

(now that it has been cut by the saw X from the rest of the board,) so as to present the back edge of the molding to the plane c, to be dressed oft. This plane c, is attached to an iron slide-plate g, which is secured to the fence la, h by the bolts f, f, which pass through long holes in the plate g, and permit it to be moved laterally and set, or gaged, so as to accommodate the width of the molding &c. The letter z' denotes another plane-stock with one or more irons to dress the edge of the remaining part of` the board &c. from which the molding,ror other thing, has just been cut, and thus prepare it to be reinserted into the machine and have another molding, Vor other stuff, cut from it. The letters Q, Q, denote rollers designed to keep the board well in its place on the bed so that the plane z', may trim the edge of the board.

The figures l, 2, 3, 4, 5, 6, denote pulleys, or wheels, around which bands or belts pass to drive the different parts of the machine. The letters h, denote the fence against the side of which the edge of the board, or other piece of wood, (from which the molding, or sash, or other thing is to be cut,) is held or pressed as it'passes along the bed. This fence consists of one or morepieces of scantling, or plank, firmly secured to the frame and at a right angle with the bed. The letter lN denotes a lever fixed to the upper end of the standard m, and having on its long arm a weight to press down the rollers n, n, upon the board, as it passes under the knives attached to the wheel M, and to hold' it snugly to the bed.

To use the machine herein described, stand at the end of it which is represented at the left hand of the drawing and present the board, plank, or other stuif, to be operated upon, with its right edge snug to that fence, and the end to the first pair of rollers D d, so that the said board, or other stuft, shall be taken between said rollers. As the machine moves, these rollers will force the board or other stuff, horizontally along under the plate G, G, and between that plate and the hollow iron cylinder armed with cutters, or knives, which dress, or plane, or trim, the under side of the board, said board being held down to the knives by the fixed upper roller D in the Vfirst set of rollers, and by the plate Gr, G. The end of the board, kas soon as it passes the edge of the plate G, G, is received between the neXt pair of rollers D d, immediately in front of the wheel M, to which are fixed the knives which shape the molding `or sash or other thing to be made. As' soon as the end of the board passes this pair of rollers it is received upon the solid bed, by which as well as by the rollers d, it is held up to thepaction of the knives fixed upon the wheel M. Y

As the end of the board '&c. moves on from under the knives, the portion of it on which the molding is now cut, passes along on the bed under the small metal roller, which turns on the pinattached to the slide N, which roller, being shaped to the molding, or other thing to be made, is enabled thereby to hold the board with its edge snug to the fence z, h, as well as to keep it close to the bed. Shortly after passing this roller, the end of the board is taken by the next set of rollers D 0l, and passed along 100 on the bed so as to receive the action of the plane-iron in the stock O, which action is so regulated by the crank-pulley S, and the apparatus connected with it, as to give a neat and smooth finish to the face of the 105 molding. The end of the board is then received between the next pair of rollers D cl, and passing through them is presented to the circular saw X, which having been rightly set on its journal, cuts off the mold- 110 been separated, presented to the planing- 120 iron to be dressed and made ready to be passed through the machine again.

What I claim in the arrangement of this apparatus herein described, as constituting a new application of old principles, to op- 125 eration in joiner-work which have not been before performed by machinery, so combined, is-

A1. The plan of rabbeting down part of the bed, in the manner and for the purpose 130 At the described; the hollow iron cylinder armed With knives under the plate Gr, G, for dressing off the underside of the boardj or other stuff; the using of the small metal roller on the pin of the slide N, shaped like the molding, or other thing to be made, and which, like the knives on `the Wheel MJ and the plane iron in the plane-stock O, is to be changed according to the shape of the Work to be done.

2. I claim also in combination the particular arrangement ofthe apparatus, for moving, or Workinge the plane O, and the plane-stocks c, and z', with their irons to dress the edges of the molding and the 15 to the machine, With the various kinds of 20 gearing, may be employed.
