- Figure l denotes a plan or top'view; Fig. 2, a side ele ration; Fig. a centra-land vertical section on line A l, Fig. i 5 Fig..4, a frontend elevation; 'Fig'. 5, a back end elevation; Figa-6', aA transverse and vertical section on line C D of Fig. l, showing parts beyond toward front end et' machine. l
- the nature of my invention consists in the arrangement ot the two screWsE, i'orelcvatingq lowering', and retaining the planining-cylinder in pbsition parallel with the face of the platat an angle varying from five degrees to fortyfive degrees from the plane or face surface ot' the cuttin;, blade ⁇ s,v as the material bein g; planed may require; also, in suspending the driveshaft S2 in moyable journal-boxes, and so connecting them to the planing-cylinder by rods or otherwise that the axis ot' the planing-cylinder Will'always be equidistant from veach other, to retain an equal uniform'l tension to the driving-belts at whatever elevation the planing-cylinder may be placed; also, in 'driving the platen back and forth by means ot' friction slide and wheel and a toothed rack and pinion; also, in starting, stopping, and reversing thefmovement ot platen by means
- planin ,fg-cylinder may be placed; also, in incasing, ⁇ 'the raising and lowering screws, which carry the cutting cylinder, Within the npriglits in which they are placed, or part to which they are attached, in order to eilectnally exclude dust, dirt, and shavings also, in providing the planing-cylinder with sectional cnttingblades, cach imparting, ⁇ or performing a shearing or drawing stroke or out, essentially as described, to eii'ecta nearly equal ont during' the entire revolution of the planing-cylinder, so as to be easily removed, sharpened, nd Ireset for use; also, in forin- :ing that on ofthe planing-cylinder which y back of the edges and in contact Wn the surface of the cutting-blades which carries the plnning-vcylinder, with the i uprights
- the screws E are ⁇ so arranged as to both be turned byone shaft I, having abalance-wheeLK, and two bevel-gears thereon, which 'gear into similar bevel-gears, H, on screws E.
- the shaft I being suspended to revolve in suitable stands, V3, which are secured. to top of cross-bar F, as seen in the drawings.
- Thejournal-boxes B3 are secured to the Vfront .of cross-head M.
- vthe cutting-cylinder 0 which is constructed-aud provided with four or more srctional cutting-blades, P, fitted and secured to surfaces so formed on cylinder 0, and not paralle] to its axis of motion, as to impart a shearing or Adrawing cut. to the material.
- These blades P extend for a section or a little Amore than half thelength of the cutting-cylinder t'. e., their inner ends overlaptomaketheiinish or cut complete or continuous the entire length of the planing-cylinder.
- the cutting'cylinderO which is immediately back of the cutting-blades P may be formed any suitable angle from tive degreesto iort'y-4 five degrees, (seen at a. b 0,) to give a good finish yto hard or soft wood, the number ofdegrecs-of angle to this portion of the cylinder being more than twenty-'five degrees for hard and less than twenty-live degrees for soft wood.
- a suitable pulley (seen at Q,) to be driven.
- the cross-head"- M and the planingcylinder are both raised and lowered and positioned, and at all times held in position by screws E univer/sally by means Vof stands V, secured to 'cross-head, these stands being divided into two parts where theyc'lasp the screws E, and between, these divided parts a universal nut, (seen at W), through which the screws E pass and to whichtheyarethreaded.
- Thefeedin g device is constructed as follows: o
- A To the under side of the platen Ba friction'- slide, A ,is secured,and also a toothed rack, B.
- journallboxesfl securedl to A support Gf at its lower or under side and vnear to its upper end by jolrrnal-box H/secured to sliding bar l" by pivot'K, so as to be b'oth "ertically adjustable, and at' the same time turn to freely allo/w the shaft E to conform to all the requiredmovements givenitv for the feed.
- the frontdogging-barW is secured to platen similar to bar U Between it and top face of platen are several sliding dogs or claws, l/,eorresponding to claws b', and movedby cam-levers'X .with eccentric slots d', pins f', and'pivoted bv screws c', to firmly secure the pieces'of lumber between-hein for .being ⁇ I constrneta cond uctory, (seenat ASl) and so connect it tocross-head M as to vconduct the dust and s havings away from the planing-cylander throughA this conductory by the force or current of air put in motion by the velocity imparted to it,
- the arms of stands E* may be swung and secured byscrcws Il* to bring either the -scraperEl or rolll)4 upon the face of the iinished piece, as ⁇ may be desired, to plane straight and out of wind.
- I l
- v weight projects over the end of the bed-piece, lthereby increasing the capacity ofthe machine so as to plane longer piecesjthan could be done by planing-machines with the saine length Of bed and provided with the waysv vating-screws E, for raising, lowering, and pO- sitioning the planing cylinder accurately with v thetop face of the platen, essentially as described, when combined with the bed-piece, which carries the platen, for dressing the lum ber, essentially as set forth.
