P LQAVNING AND SAWING MACI-FIINE.

- sPEcIFIcATIoN forming partof Letters Patent No. 287,019, dated October 23, 1883.

Application filed February 20, 1883. (ModeLl w suitable reciprocating log-carriage, whereby the surface of the log,,before the respective boards are sawed from it, can be planed, the planing operation being effected while the logcarriage is moving back for a new start of the saw into the log, and the sawing operation being effected when the planer has been swung down out of the way and'while the log-carriage and log are being moved forward.

My invention also consists in certain combinations of gear-wheels with the saw, planer,

and shaft which operates a log-carriage, as will be hereinafter described and specifically claimed, whereby the operation of either planing or sawing can be effected as follows, viz: The operation of swinging the planer out of the way of the log, in order that it may move forward against the saw, causes the gearing which propels the log-carriage forward to gear with a pinion of the shaft which drives the log-car riage directly, while the operation of swing ing the planer into position for planing the face of the log as it is moved backward causes the gearing which moves the carriage backward to be geared directly with another pinion of the said shaft which drivesthe log-carriage directly; and while these forward and backward movements are provided for under the conditions stated, the saw and planer can both, at the same instant, be thrown out of gear with the shaft which drives the log-carriage, and then the said log-carriage-driving shaft can be thrown into gear with mechanism which willgig the log-carriage back while the sawis in the log.

In the accompanying drawings, Figure lisa top View of my improved combined sawing and planing machine as adjusted for performing the planing operation upon the face of alog which has just hada board sawed from it.

Fig. 2 is a broken vertical longitudinal section of the same in the line w x of Fig. 1, the machine being adjusted for sawing off the board which has been planed. In this view the machine is represented as turned around from the position shown inFig. 1, and the planer is shown swung down out of the way of the log being sawed. Fig. 3 is a broken longitudinal section of the machine in the line 1 3 of Fig. 1, it being shown as adjusted in Fig. 1 for planing the face of the log. Fig. 4 is a broken longitudinal section of the machine in the line z z of Fig. 1, it being shown'as adjusted for gigging back the log-carriage when the saw is in the log; and Fig. 5 is a bottom view of the machine, the parts being adjusted as in Fig. 4.

In the views of the drawings, A is a station ary saw-frame, and B an adjustable swinging planer-frame,pivoted at b I) to the saw-frame. The saw G is circular, and hung fast upon one end of a revolving shaft, 0. The planer D is also circular, hung upon a revolving shaft, d, and provided with planing -bits e, applied tangentiallyin beveled throats out through its face and out to its periphery, as shown. Any other suitable construction of rotary saw and planer may be adopted in carrying out my invention. The side bars, f, of the planerframe B are somewhat in form of a cyma reversa, and these bars areconnected by transverse rods 9 and shaft (1. The planer-frame B is so applied to the saw-frame A that one of its side bars, f, moves on its pivot b against the inner side of said frame, whileits other side bar, f, swings up and down on its other pivot, I), close alongside the outer side there- ,of, as shown in'the drawings. One of the pivots, b, 011 which it swings forms a pulley-shaft, v

and upon it pulleys 9 gig are applied. From the pulley g a driving-belt, E, passes to apulley on the planer-shaft d and gives rotary motion to the planer. The saw-shaft c has pul leys c 0 provided upon it, and from the pulley c a crossed belt, a, is passed to the pulley g, and by this means the shaft 0, which revolves the saw, is made to revolve the planer. Acrossv the saw-frame A, and extending under an 61'- dinary log-carriage, (not shown,) a pinion-' drivin shaft F isa )lied and this shaft is a a 7 p 7 provlded with one or more pnnons, h, for gearing with the aforesaid log-carriage and three other pinions, h if h. Above this shaft another shaft, G, is arranged upon the sawframe, and upon this shaft a large toothed wheel, m, and two pulleys, a n, are applied, andbetween the wheel at and pulley a a long hand lever, H, is applied, being fitted loosely on the shaft G, so as to swing back and forth thereon. The lower short arm of this lever is forked,and has connected to it (by a pivot-pin) a pitman, p, which is connected to and supported by the transverse pivot-rod g of the planer-frame, as shown. On one side of this lever a bearing, 1), is provided, and in the clever and in this bearing a short shaft, q, carrying a pinion, q, and a pulley, q is hung, as shown. 1-} band, 1-, from the pulley it passes around pulley q, and thereby revolves the shaft q and pinion q.

The pinion q gears with the pinion 7t when.

the planer is swung down, as in Fig. 2. At a point opposite the bearing r another bearing, 1)", is applied upon the lever H, and in this hearing a shaft, 8, carrying two pinions, 8 s is applied, the pinion s gearing into the large toothed wheel on at all times, while the pinion 8 gears with the pinion h, when the planer is swung up into its planing position shown in Figs. 1 and 3. A band, I, passes from the pulley c to the pulley a, and thereby gives motion to the shaft G, wheel m, pulleyn, band 1, shaft q, pinion q, and the pinions s and s,- and by this arrangement of the gearing the driving-shaft F of the log-carriage can, at

.will of the sawyer, be revolved either against or from the saw. The hand-lever H is provided with a spring-catch, t, and this catch 'works in and out of adjusting stop-notches u a a of a segment 011 a standard, K, of the ,saw-frameyas illustrated in the drawings.

\Vhen the lever H is adjusted to notch 11, the planer is forced up to its planing position shown in Fig. 1 by the combined action of the lever H and pitman p of the planer-frame, and when the lever H is in notch a the planer is moved down by the same agencies out of the way of the log being sawed. The act of moving the planer up by the lever and pitman brings the gearing for reversing the motion of the shaft of the log-carriage into proper position, and moves the gearing which caused the log-carriage to travel against the saw out of gearing position with the driving-shaft of the log-carriage, while the act of moving the planer down out of the way of the log, so that the log may pass over it, moves the gearing which revolves the driving-shaft of the logcarriage against the saw in proper position .for operating and throws the gearing which moves said shaft in a reverse direction out of gear.

In order to provide for gigging the carriage back while thesaw is in the log and after the log-carriage has been thrown entirely out of gear with either the gearing which moves it backward or forward by moving the lever to V the intermediate notch, a, of the segment, a

lever, J, is pivoted to the saw-frame A, and in the forked lower end of said lever a pinion,

'v, is hung upon a shaft, w, which has a belt pulley, w, on one of its ends, and from the pulley '10 a band, 10", passes to a pulley, g on the shaft 1), which carries the pulley g, upon which the cross-belt c from the saw-shaft c is applied. By moving the lever J upward, the pinion o is made to gear with the pinion h of the shaft F, which drives the log-carriage, and thus the carriage and log are caused to move backward. To start the carriage and log forward or against the saw, the lever J is lowered to its normal position and the lever H set in the notch u of the segment.

The connection between the saw-shaft and the shaft 1) might be effected by toothed gearwheels, and if this is done the saw-shaft will be placed nearer to the planer-shaft, which relative arrangement of the shafts will probably be better than the arrangement shown. By my invention the log is planed during the time which is usually lost in gigging back the log and carriage for a new cut of the saw.
