To all whom it may concern:

Be it known that I, CHARLES A. MEEKINS, of Pine Meadow, in the county of Litchfield and State of Connecticut, have invented a certain new and useful Improvement in Planes, of which the following is a description, reference being had to the accompanying drawings, where —

Figure 1 is a plan view of a plane embodying my improvements. Fig. 2 is a view in longitudinal central section of the same on plane denoted by line x x of Fig. 1. Fig. 3 is a detail plan view of the clamping-lever. Fig. 4 is a detail view of a form of my device without the adjusting feature.

My invention relates to the class of planes in which are used clamping and slow-motion devices for the purpose of adjusting the plane iron to cut to diiferent depths.

It consists in the clamping device secured in the plane-body in front of the plane-iron, and in the adjusting device, and in the combination of these parts, as more particularly hereinafter described.

In the accompanying drawings, the letter a denotes a plane-body of ordinary form and of any desired material — as wood — having the handle b and the depthwise mortise c, in which the plane-iron d is held.

In a socket, e, in the plane-body, and in front of the plane-iron, is placed a clamping-lever, f, having the arms f’, the ends of which bear upon the upper face of the plane-iron,as seen in Fig. 4, or upon the upper edge of the rocking lever g. which forms a part of the plane-iron-adjusting mechanism. This lever f is fulcrumed on the downward-projecting lugs a’, which are fast to or a part of the plane-body, and a screw, h, operates in a threaded socket, f”, in the lever. Fast to this rotary screw h is a handle, h’, having a shoulder on its lower end, that bears against the upper surface of the plane-body. By operating the screw h the inner end of the clamping-lever f may be raied or lowered at will, binding or loosening the plane-iron.

Fast to the upper side of the plane-iron d is a cap-iron, i, curved lengthwise in such manner as to afford a space between the cap-iron and the plane-iron for the working of the rocking lever g. This lever is operated by means of an adjusting-screw, k, moving in a socket in the cap-iron, and has a round surface, g’, bearing upon the upper surface of the plane-iron, and directly opposite the bearing-face upward-projecting arms g”, that extend through an opening in the cap-iron and take into open sockets f”’ on the lower side of the arms f’ of the clamping-lever.

The parts being assenibled as shown in Fig. 2 of drawings, the plane-iron is clamped in any desired position in the mortise by means of the lever and the screw h, and the longitudinal adjustrnent of the plane-iron is effected by means of the screw k, which, by rocking the lever g while the extremity of the short arm of the lever is held in the socket of clamp,which is fixed against longitudinal motion, thus causes the iron to move.

I claim as my invention —

1. In combination, a plane-body, a, bearing plane-iron d, having a socket, e, in front of the plane-iron, in which is seated the clamping-lever f, with feet f’, arranged to press upon the plane-iron, and the longer arm of the lever moved by means of the threaded screw h, having a handle, h’, all substantially as described.

2. In combination, a plane-body, a, bearing a plane-iron, d, and having mortise c and socket e, clamping-lever f, with feet f’, which bear upon the upper face of the plane-iron, and is fulcrumed on lugs a’, fast to the plane-body, and has a threaded socket, f2, in which the screw h is operated by means of the handle h’, all substantially as described.

3. In combination, in a plane, a plane-iron bearing between the plane-iron and a cap-iron, a bent lever having a curved bearing-surface in contact with the upper surface of the plane-iron, and its shorter arm engaging a socket in the extremity of a clamping-lever, with means for operating the adjusting-lever, all substantially as described.

To all whom it may concern:

Be it known that I, CHARLES A. MEEKINS, of New Hartford, in the county of Litchfield and State of Connecticut, have invented a certain new and useful Improvement in Bench-Planes, of which the following is a description, reference being had to the accompanying drawings, where —

Figure 1 is a side view, with a portion of the sides of the stock represented as broken away. Fig. 2 is a view looking diagonally down upon the top from the point a5 over Fig. 1. Fig. 3 is a view of the plane in central vertical lengthwise section. Fig. 4. shows a detail top view of the rocking clamp-iron, and also a detail side view of the same.

The letter a denotes the stock or body of the plane, which may he partly of wood and partly of metal, or substantially wholly of wood or wholly of metal. In the drawings I show it with the bottom part composed of wood and the upper part of iron.

The letter b denotes the chisel or plane-iron, of the ordinary kind. The letter c denotes the cap-iron, which is novel in its construction; but it is secured to the plane-iron b, in substantially the ordinary way, by the connecting-screw d.

The letter e denotes what I call the “rocking clamp-iron,” because it has a rocking motion for effecting the adjustment of the plane-iron and cap-iron on the studs or pivots a’ a’; and it also serves in a novel manner the function of a clamp-iron-that is, it is the important factor in attaching the plane-iron and the cap-iron to the stock of the plane. This rocking clamp-iron runs under the cap-iron. The pin e’, jointed somewhat loosely at the bottom to the rocking clamp-iron, projects upward through the cap-iron, and upon the upper end bears the nut f, by means of which the plane-iron and cap-iron are clamped to the stock — that is, by running the nut down, the journal ends of the rocking clamp-iron press against the studs a’ a’, and the plane-iron is forced firmly down upon its seat. This rocking clamp-iron has an extended part or lever end, e”, the end of which is bifurcated, and takes hold of an annular groove in the adjusting-screw g, which is hung in the cap-iron.

By manipulating this adjusting-screw the edge of the plane-iron may be nicely adjusted. The mode or manner in which this is effected is not, perhaps, plain at a first glance; but the explanation is that by manipulating this adjusting-sorew the clamp-iron is rocked on pivots a’, and carries the plane and cap irons with it in its up and down but not its rocking movements.

I claim as my improvement —

1. In combination, the plane-body bearing the pivots, the plane-iron, the cap-iron attached to the plane-iron, the longitudinally-rocking clamp-iron, adjustably connected to the cap-iron and bearing between its points of connection upon the pivots on the plane-body, all substantially as described.

2. The oornbination of the longitudinally-rocking clamp-iron e, loosely attached to cap-iron e by pin e’ and nut f, adjusting-screw g, plane-iron b, and plane-body a, with pivot-bearings for the clamp-iron, all substantially as described.
