BENCHPLANE.

SPECIFICATION forming part of Letters Patent No. 257,981, dated May 16, 1882.

Application mea september e, reso'. (No model.)

To all whom it may concern Be it known that I, SOLON R. RUST, of Pine' Meadow, in the county of Litchfield and State ot' Connecticut, have invented a certain new and useful Improvement in Bench Planes, whereof the following is a description, reference being had to the accompanying drawings, where- Figure l is a side view of a plane embodying my said improvement-an iron planewith a portion of the side ot' the stock represented as broken away. Fig.2\is a view ot' the same plane from above,with the plane-iron, cap-iron, and fastening-lever removed. Fig. 3 is a view in central vertical lengthwise section of a moditication.

The improvement is one in that kind or class ot' planes wherein the bed on which the cuttin g-iron77 rests, the cuttingiron,(with the capiron,77 it there be one,) and the clampingor fastening-in lever all move together in the `ordinary longitudinal adjustment of the cutting,

y iron; and the improvement consists in such an bottom plate and two side plates rising there,

from. The inner sides of these side plates hear the ways b, and in them rests and slides the bed c, bearing underneath the lug d, through which a shaft, e, runs, lit bearing at the rear end a head or button whereby to rotate it, and it being threaded at the other end and there taking into a corresponding female thread made in a portion of the stock a'. Wherethis'shaft traverses the lug el it has an annular groove made in its periphery, into which the pin f meshes. By rotating this threaded shaft e the bed c is moved up and down in its ways.

The letter g denotes a fulcrum-bar carried by and upon the bed c. `'lhe letter h denotes the clamping-lever, which nds a fnlerum on this barg. One end of this lever bears on the cap-iron i, (if there be one, otherwise directly on the plane-iro11j,)'and the upper end of this l lever carries a set-screw, k, which bears on the upper end ot' the cap-iron (if there be one) with any desired pressure, and thus holds the cuttingiron, cap-iron, and itself' trmly to the bed c, so that the plane-iron can be adjusted by adjusting the bed c by means of the screw-shaft e.

In Fig. 3 I show a modification wherein the fulcrum or fulcrum-bar is attached to the clamping -lever, and, running down through the irons,7 takes hold of the bed, the irons being mortised for the passage of the fulcrnm-bar, and the bed having a mortise which permits the enlarged head or end of this bar to pass through it at one point, but catches and holds it by its neck at another point.

It will be seen from this description that the iron, the bed on which the iron rests, and the clamping-lever maybe put into and taken out ot' the stock as a whole, and th at they all move together in the ordinary longitudinal adjustment of the iron.

I am aware that the prior art contains planeirons made adjustable by a screw. See, for instance, the patent to H A. Gateley, No.1l46,588, dated January 20, 1874, which has a double iron, but no movable bed-a construction that necessitates (as my construction does not) a loosening ot' the clamping-lever before the adjusting-screw can be operated.

I am also aware that the prior art contains a combination of movable bed, plane-iron, adjustable screw or the like, and clamping-lever, .where the clamping-lever does not take its fulcrum on the movable bed. 7 See, for instance, patent to G. M. Thompson, No. 153,399, dated July 2l, 1874; but that construction does not (as my construction does) admit of the placement and displacement of the bed, iron, and clamping-lever as an assembled whole in and out of the plane-stock.

I am also aware that the prior art contains ent No. 126,519, dated May 7 1ES7.Z.-another` construction that does not admit (as my construction does) of the placement and displace IOO ment ofthe movable bed, iron, and clampinglever as an assembled whole.

which cannot be done in any structure of said 15 prior artand may be done -much more easily than when the movable bed, iron, and clamping-lever are in the stock.

I claim as my improvement- The stock ,provided with Ways bin the side zo plates thereof', the bed 0, hung in such ways, the cutting-iron j, and the clamping-lever lr, taking` its fulorum on bed c, all combined substantially as described,forthepurposesetforth.
