To all whom it may concern: thumb screw 10 operating in connection Be it known that I, MARDONIOUS L. CAR with a pivoted dog 11. TER, a citizen of the United States, residing The above described construction differs at Glassport, in the county of Allegheny and but slightly from an ordinary smoothing State of Pennsylvania, have invented cer plane Such as are now in common use. tain new and useful improvements in Com The base 1 of the middle section is rab bination Woodworking-Planes; and I do de beted or reduced to one-half its thickness clare the following to be a full, clear, and both at its forward and rear ends 2, and two exact description of the invention, such as threaded openings 17-29 formed through O will enable others skilled in the art to which the base, and suitably located openings in 65 it appertains to make and use the Salme, ref the two side flanges 3 for the reception of erence being had to the accompanying draw thumb Screws 20 and 32 for the purpose of ings, and to the letters and figures of refer securing the front and rear extensions, as ence marked thereon, which form a part of will be fully described hereinafter. 15 this specification. The rear extension of the plane consists 70 This invention relates to an improved of a flat base 27 having side flanges 31, a combination Wood-Working plane for car rabbeted or reduced forward end 28 to reg penters' use, and it comprises a plane proper ister with and engage with the reduced rear carrying the bits which in itself forms what end of the plane proper. Formed with this is known in the art as a “Smoothing plane’ base 27 are parallel arranged dovetailed 75 a detachable rear extension and means for slides 36, which extend in the direction of securing the same which when in position its length and are adapted to contain a converts said smoothing plane into a “jack sliding dovetailed strip 35, in such manner plane” or one of greater length and by a that said strip may move freely therein. 25 further addition of a forward extension in This strip 35 is secured rigidly in a certain 80 addition to that of the rear the plane an position by means of thumb screws 29-30, swers the purpose of a “fore plane’, and engaging with the threaded opening 29' in the invention further consists in the certain the base 1 of the plane proper and with a details of construction of parts as will be similar opening 30 formed in the base of 30 fully described hereinafter. the extension, as will be best seen by refer In the accompanying drawings:-Figure ence to Fig. 1 of the drawings. This rear 1, is a central side sectional elevation of my Ward extension is further secured and made improved combination plane showing the more rigid with the plane proper by means same converted into a fore-plane, the same of thumb screws 32 passing through the side 35 being constructed and arranged in accord flanges 3 and engaging with threaded open 90 ance with my invention. Fig. 2 is a similar ings formed in the flanges 31 of said exten view partly in elevation, showing the imple sion (see Figs. 3 and 5) this making a per ment converted into a Smoothing plane, the manent and riigid connection between the rear and forward extensions being adjusted parts. The movable dovetailed member 35 40 and secured above the level of the base of carries an ordinary handle 33, such as are 95 same. Fig. 3 is a plan view of the converted used on all wood planes said handle being fore plane, as shown at Fig. 1. Fig. 4 is an attached by a screw 34 at the forward end end elevation of the same. Fig. 5 is a cross and by another passing down through the section, taken on the line a a of Fig. 1. Sale. 45 To put my invention into practice and At the rear end of the base 27 of the rear 100 thereby construct a convertible hand plane extension is a threaded opening 30, and like for carpenters and joiners' use and provide openings 35' are formed in the side flanges a combination of these planes in one, of the same, by means of which together form from cast metal a middle section which with the thumb screws 32, this said exten comprises a flat base 1, upwardly project sion may be adjusted to the position shown ? ? 5 ing sides 3, extending the entire length of at Fig. 2 of the drawings, having first re said base, a cross portion 4 located above the leased the screws 29-30, moved the sliding throat 5 and an inclined integral 1'est 6 upon member 35 back until the thumb screw 29 which the bits 7 are held by means of a plate may engage with the forward threaded 5 5 8 and screw 9 and rigidly secured by a opening of the base 27 at which time the 10 948,178 side Screws 32 are adjusted to make a rigid in position as at Fig. 1, a fore plane is connection of the parts. This backward formed, the handle 33 being first adjusted movement of the sliding member 35 will to the prc per position. bring the handle 33 and adjust the other To form a jack plane it is only necessary parts to form the smoothing plane, the to adjust the forward extension to the posi whole having been moved forward and on y, tion shown at Fig. 2, leaving the rear ex the top of the base 1 of the plane proper, tension adjusted as shown at Fig. 1, and in and when in this position the forward ex Or'del' to convert the implement into a 60 tremity of the guides 36 will project be Smoothing plane the front and rear exten 10 neath an offset 26 formed beneath the in sions occupy a position as shown at Fig. 2. clined bit rest 6' and prevent any lateral The advantages of a convertible plane con or vertical movement of the extension. struction, as described are many, as is ob The forwald end of the plane proper is vious among which are cheapness, as it takes 65 also fitted with an adjustable extension, the the place of the three ordinary smoothing 5 same consisting of a base 12, rabbeted to planes required for all ordinary carpenters register with the front rabbet of the base 1, practice, and it may be adjusted to occupy side flanges 14, parallel dovetailed guides the minimum of space in a carpenter's tool 24 in which a colºresponding movable mem chest. 70 ber 23 operates in the direction of its length. Various slight modifications and changes 20 This forward extension is secured in line may be made in the details of construction with the plane proper by means of two without departing from the spirit of the thumb screws 17 and 18, together with side invention.
