sroP CHAMFER PLANE.

SPECIFICATION forming part of Letters Patent No. 272,274, dated February 13, 1883.

Application filed August 12,1882. (No modelJ' To all whom it may concern:

Be it known that I, JOSEPH LEE, of Garnerville, in the county of liockla-nd and State of New York, have invented a new and Im- 5 proved Stop Ohatnf'er Plane, of which the followingis a full clear, andexact description.

The object of my invention is to facilitate the cuttingof'chainfers of all kinds, on the edges of posts, boards, 82:0.

[0 The invention consists in a stop chamter plang formed of two parallel bevel-guides united by adjustable cross rods, and carrying a cutting-blade which can belocked in position by a binding-screw.

The invention also consists in a transverse gage for facilitating the adjustment of the implement.

The invention also consists in the construction of details and in the combinations of parts, as will be more fully described hereinafter. 1

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of reference indicatecorresponding parts in .both the figures. Y

Figure l'is a perspective view of my inproved stop chainfer plane; Fig. 2 is a crosssectional elevation of the same.

The planeis composed of two beveled guides,

0 A and B, which are parallel lengthwise, but have their sides inclined toward each otherat right angles. The guide A is provided with two npwardly-1.)rojecting lugs, (J, terminating in eyes I), nnited'by a curved handle-piece,

5 E. The eyes D are provided with bindingscrews F.' The beveled guide B is provided with upwardly-projecting lugs terminating in eyes 1), provided with binding-screws F. Two cross-rods, G, each provided near oneend 40 with a V-shapetLbend, are passed through the eyes D l), and can be locked in the desired 'position in the same by'means of the sctews F F. A graduated transverse arm or gage, H, projects from the upper edge of the guide 5 A, and passes through an eye or loop, J, on the upper edge of the bevel-guide B. The guides A andB are provided with triangular ridges or projections K Kon the upper edges, the under edges of these ridges projecting 5o downward from the rear toward the front of the plane. The triangular projection K has. a wide upper edge, and the edge of the projection K isvery narrow. The cutting-blade L is placed on the ridges K K, and is provided along one edge with a grotive, M, adapted to receive the upper edgeof the ridge K on the guide A. A binding-screw, N, held on the upper end of an inclined lug, 0, above the inclined ridge K, binds and holds tli cntting-blade L on the ridges K K The guide 6o B is provided at its rear end with a handle,

'P, of the usual construction. The cutting edge of the blade L passes into notches a in the upper edges of the guides A and B. According to the desired width of the chamfer, the guides A and B are adjusted at greater or less distance from each other, the said adjustment being facilitated by the gageH, and then the blade L is held in place by means of the binding-screw N. The inner surfaces of the guides A and B rest against the sides of the board or post to be chamfered. Plain or molded or beaded chamfers can be cut, a cutting-blade with a corresponding cutting-edge being held in the implement tor the desired chamfer. Ghamfers running the whole length of the edge of the board, or stop-chainfers, which stop a greater 'or lessdistance from the ends of the board or post, can be cut by means of the above-described implement. The han- 8o dle-piece E greatly facilitates adjusting the instrument. In operating the instrument one hand holds the handle P and the other is rested on the handle 11.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1 1. A stop chami'er plane having two parallel and relatively-adjustable bevel-guides with sides inclined at a right angle to each other, in coinbinationwith mechanism for holding said guides in their relative positions, as shown and described.

v 2. The combination of the guides A B, provided with upwardly-projecting lugs carrying eyes I) D, the curved piece E, connecting 5 eyes D and the binding-screws F F, with the two cross-rods G Gr, having V-shaped bends, passing through said eyes, and adapted to be locked in any desired position, as described.

' 3. The combination, with the adjustable roo guides A B, of the gage H, projected from the of acutting-biu de, L, having edgegroove M upper edge of guide A, and passing through and binding-screw N, as and for the purpose a, loop. J 0f the guide 13, as shown and despecified.
