SPECIFICATION forming part of Letters Patent No. 331,730, dated December 1, 1885.

Application filed August 12, 1855. Serial No. 174,191. (No model.)

shaft, I, which carries at its lower end a gear, On the opposite side of the machine, Fig. 3,

upon the shaft 1), is a small pulley, d, that is connected by a belt, 0, Figs. 1 and 2, to a large pulley, e, that is geared to drive the lower feed-rolls. The pulley e carries a pinion, f, that drives a gear-wheel, g, having a pinion, h, for actuating the gear 8 of the front lower feed-roll, which gear 5 in turn actuates an intermediate gear, t, for driving the gear a of the back lower roll.

The gearing for driving the upper and lower sets of feed-rolls independent of each other is shown in Fig. 4, and the position of the several gears is shown by broken lines in Figs. 1 and 2, the gears for driving the upper rolls being indicated by lines broken at long intervals, while the gears for driving the lower rolls are indicated by lines broken at short in tervals. By thus driving the upperand lower rolls independently upon opposite sides of the machine I am enabled to dispense entirely with expansion-gearing, and can employ to advantage lighter trains of gears than usual.

The roll-belts c c are tightened or slackened to start or stop the feed by means of two tighteners, N N, attached to arms 0 O, that are adjustably mounted on a cross-shaft, w, by means of set-screws yy, so as to permit adjustment of each tightener to the state of its own belt. Both tighteners are manipulated at the same time by a lever, P, attached to the shaft 20, and having a spring-locking pawl for engagement with a rack, Q, by which the tighteners are held in contact with or away from the belts.

On the shaft 1) are pulleys z 2, that carry belts R R, for actuating the matcher-heads S S, which, together with their usual accompanyments, may be arranged near the delivery end of the machine. These matcher-heads are adj ustably supported in the ordinary manner, as shown in Fig. 4.

\Nhen the machine is to be used for tongueing and grooving or matching lumber, and for similar purposes, matcher-guides T T will be arranged adj ustably upon the bed B, as shown in Fig. 3.

It will be observed that the pulley 6, with its pinion f, and the connected gearing for actuating the intermediate gear, m, and upper roll-gears, a n, are all mounted in one of the arms G of the frame F, so as to be adjustable therewith.

By arranging the upper and lower rolls to be driven by belting and gearing independently from opposite sides of the machine I am enabled to provide for the necessary vertical adjustment of the cutter-head and upper rolls without employing expansion-gear trains and owing to the peculiar way of gearing the front and back upper roll-gears by means of a double intermediate gear having a bearing on one of the cutter-head mandrel-boxes I can at the same time drive the cutter-head by belting at both ends. This arrangement results in giving a very strong, positive, and

durable feed, which is operated by a single tightening-lever, as before explained, and enables the cutter-head to be rotated smoothly and with great power.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a planing-machine having upper and lower feedu'olls driven independently by a belt and gearing on opposite sides of the machine, the combination, with the front and back upper roll-gears, n n, of an intermediate gear, m, arranged to rotate upon an annular bushing, 19, fitted to the outer end of one of the cutter-head mandrel-bearings, whereby the cutter-head mandrel is enabled to carryapulley at each end, substantially as described.

2. In a planingmachine, the combination of the main frame A, having inclined guideways H H on each side, the lower feed-rolls, O O, mounted in journal-boxes supported in said main frame, the vertically-adjustable frame F, having guide-arms G G, the Vertically-inclined screw-shafts I I, having gears J J, the transverse shaft- L, having pinions K K, the cutterhead E, and upper feed-rolls, D D, mounted in said adjustable frame F, and belting and gearing on opposite sides of the machine for driving the upper and lower feedrollsindependently,substantially as described In testimony whereof I affix my signature in presence of two witnesses.
