To'aZZ whom it may concern.-

Be it known that I, FRANK M. BAILEY, a

citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bench Planes, of which the following is a specification.

My invention relates to improvements in bench-planes, and has particular reference to mechanism for adjusting the cutter.

- The object of my invention is to provide a simple, convenient, and inexpensive mechanism for this purpose.

In the accompanying drawings, Figure l is a perspective view of a bench-plane showing my adjusting mechanism, and Fig.2 is inpart a longitudinal section through the adjusting mechanism and in part an elevation.

The plane in its general feature is of ordinary construction, of which a designates the cutting-bit, b the cap-iron, and A the holding cap or clamp for holding the cutter in place. I pivot an angle-lever, c, in the body of the holding cap A, with one arm of said lever pro- 2 5 jecting through the holding-cap into a hole made to receiveit in the cap-iron I in case of l a plane having a double iron, or in the cutter itself or some part rigidly affixed thereto in case of a plane having a single iron. The outer end of the lever, as shown, has two arms, (I d, which constitute the operating-handles for moving the lever to adjust the cutter up or down. These two handles are aconvenience, as by pressing upon one of them the cutter is forced downward, while pressing upon the other forces the cutter upward. Only one arm, however, is necessary, as that will operate to adjust the cutter both ways by pulling outward or depressing said arm.

The main feature of my invention resides in the adj listing-lever pivoted to the holding-cap, and having a handle which forms a part of said lever upon the upper front side of said holding-cap.

I am aware that it is old to employ a lever having one arm connected with the cutter, while the other arm serves as an operatinghandle of a plane-bitadjusting mechanism,

said lever being pivoted to the stock underneat-h and bacl; of the cuttingbit, and the same is hereby disclaimed. Such an adjusting-lever can only be reached by the ends of ones fingers, and is very inconvenient to operate, besides being in the way when grasping the handle of the plane. By my invention all the space under the frog and in front of the handle is left open and unobstructed, so that there is plenty of room for the fingers of the operator while grasping the handle, and no liability of hitting and hurting the fingers, as there is in planes having this space cramped by an adjusting mechanism. The construc tion is also very much simplified, so that the plane can be produced at a small cost. It also enables me to use a T form of lever when desired, so that the cutter can be adjusted both provided with an operating-screw for the ad justing mechanism, the handle of which screw is upon the upper front side of the holding cap or clamp, and I hereby disclaim the same.

I claim as my invention- 1. In a bench plane, the combination of the cutting-bit a, the holding cap or clamp A, and the adjusting-lever pivoted thereto and having its operating-handle on the upper front side of said holding cap or clamp, substantially as described, and for'the purpose specified.

2. In a benclrplune, the adjusting anglelcver 0, having one arm for connecting with the cutting-bit projected through the holding cap or clamp A and pivoted thereto, and the two arms dd, extending in opposite directions from the main arm upon the upper front side of the cap, to serve as operating-handles, substantially as described, and for the purpose specified.
