IMPROVEMENT IN BENCH-PLANES.

Specicationforming part of Letters Patent No. 158,302, dated December 29, 1874; application led June 18, 1874.

To all whom it may concern:

Be it known that I, CARL NORDELL, of the city of New York, in the county and State of New York, have invented certain Improvements in Bench-Planes, of which the following is a specilication The object of my invention is to furnish a handplane in which the tooth can be used shorter than in other planes, held in place and adjusted .to the proper depth of out and clearance for the shavings without the use of a double or covering tooth, or of the ordinary wedge, or the necessity of adjustment by hammering, and in which a durable metallic surface may be employed without liability of sticking to the surface of the work in consequence of the adhesion resulting from the well-known affinity between 'the metal and the rosin of the wood.

To accomplish this the invention consists, rst, in a metallic cap, adjustable by means of a screw, or equivalent, to give the desired clearance for the shavings, and tightened against the tooth by means of a cam-lever pivoted to a screw adjusted in a threaded socket, which socket is pivoted on a springwire, or equivalent spring, which latter, held in permanent position at its two ends, allows otl a yielding at its middle to any extra or over pressure ot the cam on the cap. This cap, with the cam-lever, thus does the purpose ot the ordinary double or covering tooth and tightening-wedge. Second, in the combina tion of stationary springs with movable and adjustable screw-slides operating inthe cap, and provided with cleats and stops,'in`such a manner that, when the cam-lever is thrown Aforward to loosen, but not remove, theeap,

the tooth, which is provided with holes or slots suitable to encompass the said cleats, when the upper end of the tooth reaches the said stops, may be easily inserted between the said springs and the slides, and when pushed up against the said stops will be lodged on the said cleats by the pressure of the said springs, after which the depth of the tooth, or of the cut, is regulated, by operating the slides by means of its screws pivoted in the cap. When the cam is loosened the tooth may be instantly removed, when required, by simply pressing down the rear end of the cap against the ends ofthe springs placed under the tooth. This pressure raises the forward end of the cap sufficiently to release the tooth from the cleats, and allow it to slide out through the opening in the face of the pla-ne. Third, in providing a combined metallic and wooden face of a plane by perforating or socketing the metallic face-plate, and inserting in the holes or sockets so formed one orI more dit'- t'erent kinds of hard wood, placed with its grain or fibers at right angles to the face ot the plane.

In the accompanying drawing, making a part of this specification, Figure l represents a longitudinal vertical section of a metallic hand-plane for planing wood, constructed according to my present invention. Fig. 2 is a face view ot' the same. Fig. 3 is a cross-section of the same, taken through the line m :t of Fig. l, and seen in direction of the arrow. Fig. 4L is a plan view of the under side of the tooth ot the plane. Fig. 5 is a plan view ot' the inside of the cap, with its slides and screws for adjusting the tooth. Fig. 6 is a cross-section otl the plane, taken through the line y y of Fig. 3. Y

Similar letters ot reference indicate like parts'in the dit't'erent ligures.

A are the wooden handles of the plane. B is the metallic face-plate, provided at each edge with upright flanges al, between which i are inserted and secured as well the handles A as the entire mechanism for operating the tooth. The face B is provided with numerous perforation's or sockets, into which are tightly inserted the wooden pieces bf, made of any desired shapes and sizes, in such a manner as to form a perfectly smooth and even surface with the metal. C is a metallic frame for supporting the tooth, cap, springs, and sockets, severally above mentioned, and the screw for regulating the cap to give the desired clearance for the 'shavings The frame C is provided on the outside with cleats c1 c?, and is of sufficient width outside ot' the cleats to snugly lill the space between the flanges al, and is secured to the metal ot' the plane by entering the cleats c2 tightly between the two cleats c2 ci, formed on each side of the frame C upon the inner sides ot' the iianges al, and is fastened at the bottom to the top of the metallic face-plate B by a pin,

c3. The frame C may also be secured in any other suitable manner, the mode being immaterial so long as it be held firmly in its place. D are ribs or upright lian ges ot' the frame C, upon which flanges the tooth rests when in position for work. A part of the lower portion ot' the frame C is formed into a socket, dl, placed across the face plate of the plane, through which socket, and through holes in the lower part of the anges D, is inserted a wire spring, d2, which spring also goes through and serves as pivot for the screw-socket E.

This socket E is held in a central position in the frame C by being inserted through an oblong hole, e', in the frame C, previous to the insertion, through the socket E, of the spring d2. rllhe hole, being oblong, allows of an oscillating motion of the socket E, and thus also of a sliding motion of the cap. F are springs attached, with their lower ends, to the bottom of the frame C, and bearing, with their upper ends, against the under side ot' the tooth, to force the same, when being inserted, into its proper position against the cap, and retaining it there, even when the cap is partly released for adjustment of the cap or of the tooth. rllhe upper cross-bar ot the frame C is provided with a threaded hole for the reception of athumb-screw, G, on which are formed a thumb-nut or milled wheel, gl, a shank, f,-and a button, g2. H is the cap, curved so as to touch with its forward end the lower or forward end ot' the tooth, whatever be the adj usted position ot' the cap. The rear end of the cap is formed into a downwardprojecting flange, hl, in which is a slot, h2, tting, when the cap is placed in position on the shank fl, between the thumb-nut gl and button g2 ot' the screw G, the circumference of the thuinb-nut gl projecting far enough below the edge ofthe angeJLl to allow of turning the screw G, whereby the cap H is slid forward or withdrawn, according to the clearance desired for the shavings. In about the center of the cap H is a cup-shaped slotted socket for the reception of the spherical cam of the cam-lever I. This cam is slotted, and in its slot is pivoted the upper end of a screw, I', the lower end of which enters the socket E. The cap H is also provided, at its upper or rear end, with slots h3, through which project, sufliciently far to handle, the thumb-nuts jl of the screws J. The forward ends of the screws J are pivoted in a rib, jl, forming a part of or attached to the cap H. The rear ends of the screws J are pivoted to the pieces il, attached to the rear end of the cap H. 0n these pieces l are little projections j?, forming a cavity between. them, for the reception of the rear ends of the springs F. K are slides, each threaded to form a nut, for the reception of one of the screws J, by turning which they are operated. Each slide K is provided with a cleat, kl, and a stop, k2. L is the tooth, the center of which is cut out so as to allow of its being slid back and forth without interi'ering with the screw I or socket E. In the rear ends of the tooth L are perforations ll, to receive, when the tooth is inserted, the cleats kl otl the slides K.

When the cam-lever is thrown in the position indicated by the dotted lines in Fig. l, the springs F will raise the cap H sufficiently to allow (while slightly depressing the rear end of the cap H) of the introduction of the tooth L until it is checked by the stops k2 on the slides K. Allowing the springs F to eX- pand, the tooth will be brought, with its slots Zl, onto the cleats kl. By now tqrniug either or both screws J, as the circumstances may require, by the hand-nuts jl, the tooth can be adjusted to the depth required, and its edge parallel to the face ot the plane. The cap H is then adjusted by the screw G and hand-nut gl, to give theV right clearance for the shavings. The cam-lever I is then tightened to depress the cap H, and the plane is ready for work.

Should the screw I have been turned down in its socket E too far for suiting a thicker tooth, the spring d2 will make up for the ditference by yielding enough to allow of bringing the cam-lever down to the surface ofv the cap H in ti ghtening the cam.

llo remove the tooth it is onlynecessary to loosen the cam and depress slightly the rear end of the cap H.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. rllhe cam and lever I, screw I', and socket E, in combination with the spring d2, operating as described, and with the cap H, to hold the tooth firmly in place against the ribs D ot the frame G, substantially as specified.

2. The springs F, operating as described, in combination with the pieces fil on the curved cap H, and the parts I Il E, for the insertion and removal ofthe tooth L, and retaining the same while being adjusted, substantially as and for the purpose specitied.

3. The screws J, working in the cap H, and provided with thumb-nuts jl, the slides K, with their cleats kl, and stops 7a2, in combination with the tooth L, provided with the slots l', for the purpose ot' adjusting its position, substantially as and for the purpose specified.

4. rllhe cap H, regulated by the screws G, the tooth L, regulated by the screws J and slides K, the cam and lever I, screw l', socket E, and springs d2 F F, in combination with the frame G, face B, and handles A of a plane, to operate together in the manner and for the purposes substantially as specitied.

5. rllhe face ot' a plane, constructed by inserting pieces of woodb in a metallic faceplate, B, with the bers at right angles to the face, substantially as and for the purpose specified.

The above specification of my invention signed by me this 15th day ot' June, 1874.

CARL NORDELL.
