SPECIFICATION forming part of Letters Patent No. 745,260, datedNovember 24, 1903.
Application filed December 2, 1902. Serial No. 138,534. (No modela v a continuous cut. The machine does the work heretofore done by the hand smoothing-plane, which for fine work is necessary in order to remove the hollows and ridges left upon the surface by planing-machines with rotating cutters. Means are provided in this machine for graduating the cut to a very fine degree, to controlling the feed-pressure `by elasticfaced rollers, to prevent any marring of iinelyfinished surfaces, and to delicately present the work to the cutter, which removes a very thin continuous shaving, toy regulate .and vary the position of the feed-rolls relative to the cutting-knife for varying thicknessesof stock, automatic means to release the feed when meeting an obstruction, means to out up the continuous shaving after it leaves the knife, and other improvements which will be set forth in the specification.
The invention is illustrated in the accompanying drawings, in which like parts are designated by similar reference characters, and wherein- Figure 1 is a side elevation. Fig. 2 is a plan or top view. Fig. 3 is an enlarged detail of the'pressure-links. Fig. 4 is a section on line `X X, Fig. 3. Fig. 5 is a section on line Y Y, Fig. 3. Fig. 6 is a cross-section of the machine on line S S, Figs. 1, 2. Fig. 7 is a section on line Z Z, Fig. 2.
knife-throat and the adjustable throat-plate. Fig. 9 is a section on line V V, Fig. 8. Fig. 10 is an enlarged side view of the knife. Fig.`v
Fig. 8 is a` partial view of the table-top, showing the.
slotted holes 8 in the stands. Lugs 9 depend from the stands over the outer edges of the table and are tapped for screws 10, which are secured from end movement in lugs 11, formed on the table. By this means the feedrollers are adjusted longitudinally to their proper'relative position to the knife-edge. The stands have sleeves 12 13, forming bearings for a pivotal driving-shaft 14 ,and also for a feed-roll swing-frame 15. The frame 15 has at its center, on each side, bearings 16 17, carrying shaft 18, on which are secured a seriesof independent feed-rolls 19 2O 21, the rolls being provided with yielding bands or faces 22, such as rubber or like material, and adjustablylocated above the knife. On the inner end of shaft 18 is a gearA 23, engaging a pinion 24 on shaft 14. At the same end of shaft 14 there is a tight pulley 25 and a loose pulley 2G, on which is placed the belt to drive the machine. At the inner or opposite end of shaft 14 is a pulley 27, Vcarrying a belt 28, which runs over idler pulleys 29 30 to a pulley 31 on shaft 32, supported in bearings 33 under table 4.
Arotary shaving-cutter is secured to shaft 32 and comprises heads 34, to which are secured spiral knives 35 36 37 to cut up the long shavings as they pass from the fixed knife 38 and rotating against a knife 39, secured to the table 4, the cutter and knife being located in the direct path of the escaping shavings, which they divide intoshort sections. As they leave the knife in long ribbons, they pass naturally to the'knife and cutter without the necessity of any guiding means. TheA VXed knife is secured to anangle-plate 40 of a removable block 41,- which is arranged to tral top part of table 4. Tap-bolt 43 secures the knife and its cap 44, while screws 45 secure the cap to the knife. A ledge 46 `is formed on plate 40 and has adjusting-screws The knife, being thus adjusted very finely, is then securely clamped by the tapbolt 43 and the usual clips at the ends of the knife. (Not shown.) To still further provide '-for ne adjustments of the knife to do its work, a throat-plate 49 extends across table 4 in block 41 and beyond the block at one end and is tapered on its lower side 50, and at its thickest and overhanging end a lug 51 IOO passes down by the table edge, and a screw 52, passing through the lug and into the block, is the means employed to move plate 52 in end and by its taper raise or lower its upper surface, which is parallel to the knife-edge, to adjust the depth of the out. The plate when adjusted is secured from movement by screws 53 54.
The feed-rolls 19 2O 2l must be adj usted as to height to feed stock of different thicknesses. The feed-roll frame l5, being pivoted on shaft 14, its opposite end must be raised or lowered to raise and lower the feed-rolls for the purpose of sufficient grip for feeding in the stock and also for yielding to thick or thin places 1n the stock and obstructions, and means provlded to secure their position. For such purpose a shaft 55 passes through bosses 56 of the frame and extending beyond the frame at each end enters a box 57, inserted in the upper end of an adjustinglink 58, having screws 59 above and below the box for its adjustment. Links 5S pass down by the side of table 4, which has a shaft 60 passing across within it and extending beyond its sides and through slots (il in the links. On shaft GO are pinions 62, engaging racks 63, formed on the links, so that as the pinions are rotated the links, swing-frame, and feed-rolls are moved up or down. Shaft 60 has a head 64 at its farther end bearing against the hub of the outer pinion, and on the near end of the shaft is aV screw-thread 65, on which is a hand-wheel 66, bearing against the adjacent pinion-hub, so that by means of the shaft-head and handwheel the pinions areforced to the linksand the links to the sides of the table 4, clamping all fast when the rolls are properly adjusted. Shaft 60 and its pinions are rotated by means placed upon the square part 67. It is sometimes desirable to have the rolls automatically adjustable to inequalities in thickness of stock or to pass an obstruction without forcing it to the surface of the stock suiiiciently to mar it. For such purpose a knee 68 is secured to the link 5S in manner for its vertical adjustment and security after adj ustment. The knee when secured and in its The weight holds the links down, but permits them also to raise when it is overcome.
The feed-rolls are made in separable Wheels instead of one, as it is more practical to secure their covering, and in case one roll becomes more worn than another-as, say, the middle one--on account of feeding much narrow stock they may be interohanged, thus greatly prolonging their use before requiring new covers.
I claiml. In a xed-knife planing-machine, a table having a removable cutting-knife stationary within a removable block therein, a series of resilient-faced feed-rolls in a frame pivotally supported upon a horizontally adjustable shaft at one end, and upon verticallyadjustable links at the opposite end, means to adjust the links and thereby the rolls and frame vertically, driving means upon the horizontally-adjustable shaft aforesaid, connected to means on the feed-roll shaft for driving the feed-rolls at a different speed.
2. In a iixed-kni fe planing-machine, a table, a removable knifeblock seated therein and wherein the knife is adjustably supported, a series of soft-faced feed-rolls supported above the knife upon a frame pivotally supported at one end upon horizontally-adjustable brackets, and upon vertically-adjustable links at the opposite end, means upon the links to limit the downward movement of the frame, without restricting its upward movement.
3. In a fixed-knife planing-machine, a table, a knife removably secured in the table, multiple resilient faced feed rolls supported above the knife on a frame which is pivotally supported at one end on-the table aforesaid, a shaft extending across the opposite end of the pivoted frame, boxes upon the shaft and adjustably supported in links, a shaft across the table below its top and extending beyond the table sides, means upon the shaft to elevate and depress the links, and thereby the feed-rolls and their pivotal frame, and means to clamp and hold the links when adjusted.
In testimony whereof I affix my signature in presence of two witnesses.
