IMPROVEMENT IN GARPENTERS PLANES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, RUSSELL PHILLIPS, of Gardiner, in the county of Kennebec, and State of Maine, have invented a new and useful Improved Joiners Plough; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others to make and use my invention, reference being had to the accompanying drawings, formi-ng part of this specification, in which- Figure 1 shows a side elevation of my invention.

Figure 2, a portion ofthe top of the horizontal arm, having the graduated scale.

Figure 3 is an end view of my invention, and a view of the top ofthe end and slides.

Figure 4, a view of a portion of the reverse side of Eg. 1.

Figure 5, an edge view of the iron or cutter.

Figure 6, a portion of the adjustable guide or gauge.

Same letters showlike parts.

My invention has relation to that tool employed by `certain mechanics, joiners, die., called a plough, and consists iu certain improvements thereupon, which maybe separately or conjointly used.

I will now describe in detail the dilferent improvements combined in my invention. a shows the groove in which the iron or cutter is placed. It is there secured by means of the clamp b and slide e. Fig. 4 shows the manner in which the slide c is held in place, being by means of a slot and a lip, d, on the side opposite to the one shown in iig. 1. The lip cl overlaps the edge of the slot, shown in fig. 4. eis a small projection, to rest against the end of the cutter, so that its edge shall not become dulled by striking or touching any part of the stock. The cutter is fully described hereafter. The cutter, being placed in the groove a, is secured as follows: As illustrated in iig. 4, the slot in which the slide c moves is' curved, so that when the slide is pressed downward, or toward the bottom of the plough, the clamp 5 is pressed upon the cutter; and when the slide is moved up, the clamp is'released or loosened, and its pressure upon the cutter taken away. The clamp b swings on its pivotf. Place the cutter in the groove a, pressthe slide downward, thus forcing the clamp b upon the cutter, and the cutter is held in place. In this method there is this advantage: With the old form of fastening the cutter or iron, when the wedge that holds it is driven inward by the blow of the hammer or other implement the entrance of the wedge within vthe stock carries with it, somewhat, the cutter, so that when the cutter has once been adjusted as the mechanic desires, it is made to project further, by being carried inward with the wedge which holds it. Besides this inconvenience, it is dificult to adjust readily. With my invention, the cutter is placed in the desired position, so as to cut into the lumber the desired deptlr,` and can then be immediately fastened by pressing the slide c downward. Moreover, as the 'clamp b does not slide at all, but simply pushes against the cutter, the cutter is not moved in the lea-st from the desired position, but remains as placed by the user. g, fig. 5, shows the iron or cutter; this has a cutting edge at both ends. These two can be made of different sizes and widths, as seen in the drawing, so as to cut grooves or channels of different widths and sizes. It has a groove, L, to fitover the edge z', to aid in holding it securely. The end of the cutter not employed passes into the recess behind the projection e, and thus its edge is kept from injury till wanted. 7' is a thumbpiece, for convenience in placing the cutter in its place, and to strike upon with a hammer to move the cutter up or down slightly when it is held by the clamp b. k lc are the cutting edges of the iron. Z Z Z Z show points projecting beyond the edges lc k, which enable the iron to do its work not only with but also across the grain of the wood. These points are sharp, and cut the fibres of the Wood before they are reached by the edges 7c, and thus prevent tearing or breaking out of the work.y A shows the single horizontal arm employed in my invention, and upon which the guide or gauge B slides. Upon its top is achannel, with the graduated scale, so that the distance that the gauge is set from the cutter g can be accurately adjusted. Upon this there is no screw: thread, as upon the old form of plough, and, as before remarked, I use-but a single arm. This admits of a much easier, more accurate, and readier arrangement for use. The gauge or guide E is made of metal, and has n portion, n, which turns on a hinge, and can be lifted up so as to leave the space 0. Theobject of this will be hereafter described. p are slides, one on each side of the stock of the plough, near the forward end, movinginl recesses, and held at any point. by the thumb-screw g, which slides in the slot r, shown in grl by the dotted lines, These slides have at theirbottoms the horizontal plates s, one on each side of the `plate t.' The combination of these devices forms a gauge by which the degree of the penetration of the cutter g into the wood canbe governed. By loosening the thumb-screw q, the slides may be raised or lowered, as desired, on either side of t, (see fig 3;) and, as seen in iig. l, the cutter is intended to rest against the side of f, so that the depth ot' the Agroove to be cut can' thus be exactly controlled, and meusuredby the graduated scale rc on the end of the stock, (see fig. Most of the work to' be'done by this tool isnear the edge, of boards or other wood. In such a case it mightbappenthat the gauge or guide B could not be brought sutl'iciontly near the plate t on account of the projection of the horizontal plates s. This I obviate by the arrangement shown in fig. 6,'before described. When the trap 'n is lifted, as seen in the drawing, the gauge B can be brought quite close to t, one ofthe plates s entering the space o. In use, 'one hand of, the mechanic rests upon the guide B, where a wooden handle is supplied. The handle upon the-stock` is seenA at D, being placed at the end ot` the stock, and lower down than is ordinary, with the view that the force `applied to the tool is all or nearly all exertedin a horizontal direction, which lessens the labor of using the plough, and makes it more effective. The handle is secured by the removable bolt u, so that if broken the handle can easilyr be taken offy and another substituted. All the .parts described, except the arm A,handle D, vand a portion ofthe guide B, aremade of metal, which makes the whole tool cheaper, less cumbersome, stronger, andmore convenient. The clamp b being made of metal, quite smooth, and slightly rounded, enables the tool to clear itself` quite readily of the shavings made in using it.` 4The method of connng the gauge or guide B at any desired point is by the use ofthe thumb-screw m.

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

1. The reversible cutter shown intg. 5, as and for thepurposes specified. 4

2. The arrangement of the two slidespp, thumb-screw g, slot r, plates s s, graduated scale x, and plate t, as and for the purposes set forth. t v n RUSSELL PHILLIPS.
