To all whom it may concern:

Be it known that I, ARTHUR T. GOLDSBOROUGH, a resident of the city of Wlashington and District of Columbia, have invented certain new and useful Improvements in Metallic Bench-Planes, of which the following is a specification.

The nature of this invention relates to improvements in metallic bench-planes; and it consists in certain novel details of construction and arrangement, the particulars of which will be hereinafter fully described.

In the accompanying drawings, Figure 1 is a longitudinal section, in elevation, of a plane illustrating my invention. Fig. 2 is a plan view of the stock and handle, a portion of the upper part being broken away. Fig. 3 is a section in elevation on the line 3 3 of Fig. 1. Fig. 4 is an inverted plan view on the line 4 4 of Fig. 1. Fig. 5 is a detail view of a portion of the bit and its adusting-screw.

Similar letters denote like parts.

A represents the stock, and B represents a bridge or portion connecting the sides, in which moves the main or adjusting screw C. The bridge in this case, being only apertured to carry the said screw and not slitted for the insertion of the bit, may be made smaller and thinner than heretofore, and yet be possessed of the requisite strength and rigidity. Under the bridge, and in close proximity thereto, are two small short cleats or studs, b b, and directly above the throat H is located another cleat or stud, b’, both sets being arranged in the same line with respect to the throat of the plane. The bit D is formed with a T-shaped slot at its upper end, and the adjusting-screw C is provided with a corresponding head,which is T- shaped in cross-section. When in position, the bit may be moved freely up and down between the cleats by means of the said screw. The bit is inserted from below through the throat of the plane, as shown in dotted lines, Fig. 1, and some means must be provided for allowing sufficient movement of the said bit for it to be placed over the head of its adjusting-screw. This may be accomplished in several ways — as, for instance, forming the bit of a width less than that of the stock between the upper and lower set of cleats, or making one of the upper sets of cleats removable, or by forming triangular recesses E in the stock, within which recesses the upper end of the bit can be raised out of the path of the main or adjusting screw sufficiently to allow it, when only partially inserted, to be placed over its head. The motion of the screw is then reversed and the bit drawn in between the upper set of cleats as far as maybe desired. I prefer the latter plan, as it allows the use of a somewhat wider bit in proportion to the thickness of the sides of the stock, unless, as in the first-mentioned method, they (the sides) be made very thin. The bit, having been inserted loosely, is secured in position as follows: At a point about midway between the bridge and throat, and attached to the inside of the sole ofthe stock, is located the supplemental bridge F, in which is mounted the set-screw G, which has a conical or wedge-like end, g. The said bridge and screw are preferably placed at such an angle that the point of the screw G will strike the inside of the sole and the under side of the bit at equal angles, so that the force exerted by it, when tightened so as to lock the previously-adjusted bit, will be evenly distributed between the parts with which it is in contact. The rear portion of the stock is provided with the inwardly-extending ribs L L, the inner sides of which being oblique, they form together an inverted-V-shaped groove or slot.

The handle I is preferably made of cast-iron. It is provided with the internal-screw-threaded boss J and set-screw i, and the foot I’, which has extending or spreading sides K K. When the foot of said handle is inserted endwise into the V-shaped groove and the set-screw tightened against the sole of the stock, the handle will be securely held. By loosening the said screw i, the handle can be readily removed, and the said screw is intended to be arranged for operation by hand or with a screw-driver, as most convenient.

Having described my invention, I claim —

1. A bench-plane having a single bit and a detachably-connected adjusting-screw arranged inline therewith, and adapted to move said bit longitudinally in its plane of adjustment, a stock provided with rigidly-fined inward projections arranged on parallel lines on each side thereof, between which the bit is held and moved, and means for locking the adjusted bit by forcing it obliquely upward against the projections of the stock, as set forth.

2. A bench-plane having a single bit, an adjusting-screw detachably connected thereto, a stock formed with spaces or recesses leading obliquely upward from the throat and adapted to allow the upper end of said bit to be moved at right angles to its plane of adjustment while being connected to its adjusting-screw, and a set-screw arranged to exert pressure below said bit and lock it in its adjusted position.

3. In a bench plane, a stock formed with a bridge connecting the sides thereof on the line of the cutting-bit, and adapted to support a screw for controlling the longitudinal adjustment thereof, and a supplementary bridge located below the bit and adapted to support a set-screw operating between the bit and the inner side of the sole, cleats projecting inwardly from the sides of said stock, between which said bit moves and is adjusted, and a recess or space between the lower and upper cleats, within which the bit may be moved at right angles to its plane of adjustment, as set forth.

4. The stock A, formed with bridges B and F, the cleats b and b’, and recesses E or equivalent, substantially as shown and described.

In testimony whereof I have hereunto subscribed my name this 19th day of July, A. D. 1883.

To all whom it may concern:

Be it known that I, ARTHUR T. GOLDSBOROUGH, a resident of the city of Washington and District of Columbia, have invented certain new and useful Improvements in Metallic Bench-Planes, of which the following is a specification.

The nature of this invention relates to improvements in construction and arrangement of metallic bench-planes, the object of which is to reduce the number of working parts, and by promoting extreme simplicity of form to reduce the weight, cost, and liability to disarrangement of the several elements of which the tool is composed.

It consists in forming the stock in which the bit and its adjusting-screw are mounted with guiding and retaining cleats arranged in the same line as that of the bit, and between which it moves, and also with a projection near the throat on a somewhat higher line, and over which the bit is forced by its adjusting-screw when being brought to the cutting-point, which operation springs it slightly out of line, securely locking it against the several projections mentioned and hereinafter more fully described.

In the accompanying drawings, Figure 1 is a longitudinal section in elevation of a plane, illustrating my invention. Fig. 2 is a plan view of the stock, a portion thereof being broken away to show the cleats and projection or deflector. Fig. 3 is an inverted plan view on line 3 3 of Fig. 1. Fig. 4 is a detail view of parts of the bit and its adjusting-screw.

Similar letters denote like parts.

A represents the stock, which may be of metal, wood, or any other suitable material, but is preferably made of cast-iron.

B is the bridge, formed integral with the stock, and, being at the extremity of the path of the bit, it supports the adjusting-screw C, and also unites the two sides of the stock. The bridge is provided with a slit, b, through which the bit D is inserted and withdrawn; and it also has the threaded aperture b’, which carries the adjusting-screw G. The bit D is formed with a T – shaped slot at its upper end, and the screw C has a corresponding terminal, c, which is T- shaped in cross-section, so that the screw and bit are, when associated together, at all times detachably connected.

E is the throat, the rear interior edge of which is thickened or raised, so as to form the projection or deflector F.

G is a cleat, preferably forming an extension of the material of the stock, and it extends from the under side of the bridge to the deflector, terminating below the highest part thereof, and serving as a guide to direct the course of the bit when being inserted, so that the cutting-edge shall not come in contact with the deflector, but only the beveled under side of the bit.

G’ is a cleat extending about one-third the distance from the under side of the said bridge toward the throat, and parallel with the other cleat, G, with sufficient space between the two to allow the bit to pass freely up and down.

The operation of my device is as follows: The bit is placed in the slot d and moves freely down between the cleats until its beveled under side reaches and rests upon the deflector F, when its downward passage will be arrested. The screw C, having been connected to the bit when it was inserted, is now turned and the bit forced downward. Being held between both cleats at its upper portion only, the edect of this will be to spring the bit forward and obliquely upward, to enable it to pass over the deflector until its edge reaches the operative point, when the said bit will be tightly held between the highest point of the deflector and the short upper cleat, G’.

It will be readily seen that the deflecting device may consist of short cleats or projections attached to the side of the stock, near instead of at the throat of the plane, and they may also be placed above as well as below the bit, if found desirable.

Having described my invention, I claim —

1. A bench-plane having a single bit, and means for moving the same longitudinally, and a stock provided with fixed projections arranged in the path of the cutting-bit, but on different lines, between which projections the bit is held when forced to its operative point, as set forth.

2. A bench-plane having a single bit and detachably-connected adjusting-screw, and a stock formed with cleats, between which said bit. moves freely, and a deflector at or near the throat, over which the bit is forced to its operative point by its adjusting-screw, and between which deflector and cleats it is securely held, substantially as set forth.

3. In a beneh-plane, the stock A, formed with a guiding-cleat extending from the point of insertion of the bit to and terminating at a deflector or raised portion at or near the throat, and a cleat arranged above and parallel to and only a portion of the length of the said guiding-cleat, between which short cleat and the defleetor a cutting-bit may be securely held.

4. In a bench-plane, the combination, with the stock A, provided with slotted and screw-threaded bridge B, uniting the sides thereof, cleats G and G’, extending inward from the sides of the slot, and deflector or projection F, at or near the throat of the plane, of the bit D and detachable adjusting-screw C, all constructed and operating substantially as shown and described.

In testimony whereof I have hereunto subscribed my name this 19th day of July, A. D. 1883.
