I 'he Schedule referred to in the'se Letters Patent and making part -of the'same.

To ail '1v/wm it may conce/rn:

.Be it-known that I, Ennis H. Monats, of Canton',-

in the county of Stark and Stateof Ohio, haveinf' vented a new and valuable Improvement in'Molding- Planes; and I do hereby declare that the following is a'full, clear, and exact descriptionl ofthe construction andoperation of the same,".reference being had tothe annexed drawing making a part of this specification and tothe letters and figures of reference marked thereon. K

Figure lfof the drawing is a. top view of my plane;

Figure 2 is a side elevation, with the side plate removed; I

Figure 3 is a ,vertical transverse section;

Figure 4 is a bottom view; and

Figures 5, l6, and 7 are details.

My invention 'has relation to an improvement in planes; and y vIt consists in providing a plane-stock with an adjustable face, capable of being molded or shaped to suit a plow-bit of any form; also, in attaching to the plane-stock an adjustable extension-gauge, designed to enable the bit to he run at any desired distance from the edge of aboard or panel, as hereinafter described. f

The letter A oi'v the drawing designates my plane? stock, which may be similar in itsr external form to the ordinary plane-stocks in common use. The under side of the stock is channeled or excavated'from side to side to receive the thin vertical sections which constitute the adjustable face of the stock.

B B represent elongated recesses or ways extending up into the body of the plane-stock, from the channel at thehase, at an angle of forty-live degrees, or corresponding to the angle of the bit. These re` cesses serve to receive the offsets from the face-sections, presently to he described. Usually I make one of these recesses in front of the throat ofthe plane, andtwo in rear thereof.

C designates the adjustable face of my plane-stock.

' This is composed of two sets of thin vertical strips d, running in the direction of the length of the planestock. One set of these strips is situated in front yoi the bit and the other is placed Ain rear, following the bit.

Each strip of the first set is provided with an offset or guiding-arm, e, which' extends upward and backward at an angleof forty-live degrees, or parallel to the bit, into the recess B.

Each stem c is provided with a projection, 7l., at its upper forward corner, which is designed to engage with a stop, k, in the wall of the recess. The arm e is arranged to slide up and down in its recess, the dis` tance to which it can descend being regulated by the 'position of the stop it and the projection h.

' Each strip of the second or rear set is provided with two guiding-arms f fg-extending upward and rearward, parallel to the arm of the strip-in front ofthe y bit, which immediately precedes it.

The forward arm f of the rear strip is Without a stop, and slides in a recess formed in the rear wall or the throatof the stock` The rear arm f is similar to the arme ofthe for ward strip, being Vprovided with'a projection, and arrangedto engage .with a stop in the wall of its recess which limits the descent of the strip. These stops-k are placed in the-recesses in such a position that they will allow the strips to descend as far as the lowest point of any one of-the ordinary plow-bits in use.

These strips'or sections d are usually made thin, in order that they may vconform as closely as possible to the configuration of the edge of the bit. The faceedge of each strip is'transversely rounded, or beveled on each side.

D' D represent set-screws, passing through the walll ofthe plane-stock, and serving to secure the strips in their relative position to each other and to the 'oit after they have been properly adjusted and molded in form.

Elrepresents my bit, whichis provided with a means of shaping the adjustable face of the stock to suit its cutting-edge.

This consists of a notch or indentation, c, formed in its .upper edge, and correspondingprecisely in shape with the edge ofv thebit, with the exception that the general curve' or prolile is reversed and flatter.

The face-sections' having been adjusted out to ill vthe mold the set-screws are tightened, and the Vstrips thereby rigidly secured in position. f .The bit and wedge are now inserted in the throat ofthe plane-stock, and, having been properly adjusted, the too'l ,i's ready for operation. This stock, with its adjustable face, may he used 'with a stationary gauge, but usuallyI prefer to attach to it my extensiomgauge, as follows: j

At the base of the exterior wall of the stock, on the left or inner side, is formed a projecting ledge, G, which extends usually the entire length ofthe stock.

At the forward end a circular projection is raised, which serves as a bearing for the inner end of the extension-bar H.

A slot, l, traverses longitudinally the rear portion ofthe ledge G.

The underside of the ledge G is recessed atv-c, on each side of the slot l,to receive the ilanches of the nut n.

Krepresents a clamp-screw, by means of which the inner end .of the extension-bar H' ispivoted tothe ledge G. The end of this clamp-screw passes through the slot l, and, engaging with the square nut n, serves to x thebar H in any desired position.

The bars H andH cross'each other, and are pivoted together at about their middle portions by the pivot a". The outer end of the bar H is bent downward in order to bring it on a level with the outer end of the bar H. y

Z represents the movable gauge-bar. The upper and inner corner of this bar is recessed at s to receive the ledge G, thus permitting 'the face z' ofthe gauge to be brought up close to the bit, when desirable.

The outer end of the bar 'H' is pivoted to the forward end of the gauge-bar Z.

The 'rear end of the gauge-bar Zs slotted at Z' to receive a clamp-screw, K'whioh' operates, in conjunction with a nut, n', to secure the outer end ofthe bar H at any point of the slot.

The distance to which the gauge can be extended from the bit is regulated by the length of the Acrossbars H'H' and the length of the slots l l'. The gaugebar, when adjusted at the proper distance from the bit, can be rigidly fixed in that position by means of the clamp-screws K K'.

- A plane constructed in this manner is designed to snbserve purposes of great importance to cabinetmakers and carpenters. To journeymen especially it will prove a great convenience in the saving that will ensue in transportation, one 'stock being sucient for all the bits that they may employ. Carpenters, even of small means, can execute a great variety of moldings,

limited only by the number of diierent bits which theyl may possess. 4

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A plane-stock, having yan adjustable face, capaf 'ble of being varied in form to suit bits having differently-shaped cutting-edges, substantially as specified,

2. Theoombination, with a plane-stock provided with/a'slotted ledge, G, ofthe slotted gauge Z, cross-` extension arms H H', ,and clamps lK K, substantially as specified.

3. The combination, with a plane-stock having an adjustable face, of a bit, provided with 4a forming indentation, substantially as specified.

In testimony that I claim the above I have hereunto subscxibed my name in the presence of two witnesses. l
