PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 385,895, dated July 10, 1888.

Application filed Decemberl i, 1887. Serial No. 257,891. (No model.)

To aZZ whom, it may concern:

Be it known that we, SOLOMON A. \Voons and JOHN R. THOM.\.s, of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and use ful Improvement in Planing Machines, of which the following is a specification.

Our invention relates to planing-machines; and it consists in certain new and useful constructions and combinations as an improve ment upon the mechanism for which Patent No. 364,743 was granted to S. A. \Voods, June 14, 1887, substantially as hereinafter described and claimed.

In the drawings, Figure l is a side elevation of a planing-machine containing our improve ments. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged view of a portion of Fig. 1. Fig. 4 is an enlarged view of a portion of Fig. 2.

This machine is intended to form a. tongue or tongues on the edge of the board by means of horizontal cutter-heads projecting from the sides of the bed of the machine above and below the latter, and provided with the necessary adjusting attachments for the same; and this invention consists in an improved method of mounting said horizontal cutter-heads and connecting said adjustments thereto.

A is the frame of the machine. Bis the up per cylinder. B is the lower cylinder. F F F F F F are the feedrolls. 0 O are the side cutter-heads for forming the grooves in the outer edges of the boards. D is the removable central guide,which, with the side guides, c" c", is used to guide the lumber through the machine. These and other common and wellknown parts of the machine are constructed substantially as shown and described in said former patent, and need not be more particularly described. The guide D, extending longitudinally through the center of the machine, separates the two boards which are being simultaneousl y tongued and grooved, the cutter heads EEsimultaneously forming the tongues on the inner edges of the boards on each side of the central guide, substantially as in the said lVoods patent.

The horizontal cutterheads E E, which form the tongues, are placed between the first pair of feed-rollers F F and the upper cylinder on the feed-in side of the latter, E being the upper head, and E the lower. Their location in this position enables the main cylinders to remove any roughness and splinters from the surface of the board which these tonguing-cut ters may form in cutting the tongue. As they must necessarily, when located in this position,

be quite near the main drivingshaft s, from which they are belted, which is located at the fcedin end of the machine, it is found that the adjustment of these heads vertically to vary the size of the tongues and finish the edge of the board alters the tension of their drivingbelts. \Ve therefore overcome this difficulty by mounting them on inclined. ways 0 c, placed at such an angle to the shaft 8 as to cause the belt to remain substantially at the same tension as the heads are adjusted vertically, the ways 0 having the upper cutterhead, E, 0 mounted upon them, and the ways 0 the lower one, E. These ways 0 care formed on brackets m m, extending upward and downward from and bolted to the main frame A. The inclined ways 0 on theirbracket m are attached 7 5 to and project upward from one side of the main frame A, while the inclined ways a on their bracket project downward near the other side of the machine.

The cutter-head E is mounted on shaft 8 which projects inward from one side of the machine and passes through bearings in the block or slide 0, in which it revolves. This slide is fitted toits ways a, and slides up and down upon them to adjust the cutter-head E 8 vertically. The cutter-head E is mounted upon the horizontal shaft 8 which projects inward above the bed from the opposite side of the machine, and passes through bearings in the block or slide 0. This latter slide is 0 mounted on horizontal ways in the slide 0 and is adapted to move horizontally therein. This horizontal adjustment is only sufficient to enable the cutters on head E to be brought exactly over those of head E, thus saving the time required to adjust these cutters in the heads accurately by hand. These cutters must, of course, out the upper sides of the tongues on two boards on each side of the con tral guide, D, as described in said patent to me \Voods, and the opposite side of each tongue must be of exactly the same depth, which is attained by the foregoing adjustment. The slide 6" is mounted upon the inclined ways 6, to which it is fitted by a suitable slot or groove so as to move up and down thereon. The upand-down movement of the slide 6 upon the ways 6 is regulated by a screw, 1'', which is journaled and revolves in a lug, i projecting from bracket m, and has its thread tapped through a lug, 2' projecting from the slide e On the upper end of this screw is a bevel-gear, i, which serves to revolve it by means of the bevel'gear i upop shaft 8 This shaft projects beyond the front side of the main frame and is squared on the end (see Fig. 4) to receive the crankwrench o (Shown in Fig. 2.)

The movement up and down of the slide upon its ways 6 is controlled by a similar upwardly-projecting screw, i, journaled in lug 0" upon bracket m, and havingits thread tapped through lug 1'" upon slide 6. The lower end of this screw is provided with a bevel-gear, i, which engages with the bevelgear i upon the shaft 8. This shaft projects beyond the same side of the frame, which supports it by suitable bearings, and is also squared at its outer end to receive the crank- Wrench, if desired.

Pinions 12 p are attached, respectively, to

shafts 8'' 8 so that an adjustment of one slide,

6, will adjust the other, e, or vice versa, if desired, by means of a third pinion, 19 meshing into them, as shown in Fig. 1 but this third pinion may be removed and shafts s" s separately revolved, if preferred.

The slide 6 has projecting from it a lug, o,

' in which isjournaled the horizontal screw 0,

having hand-wheel 0?. The thread of ,this screw is tapped through the lug 0 which is attached to theslide c. This affords adjustment horizontally and longitudinally of shaft s for the slide 6 and cutter-head E, to bring it into proper position with cutter-head E. A rock-shaft, R, isjournaled in the lug 0 and in another lug, 0, upon slide e. Upon it is attached the horizontal arm r, provided with a weight upon its outer end, and a finger, r, which bears against the face of slide 6 and holds it from dropping down. Pressure-fingers r r are firmly attached to this rockshaft and curve downward and forward in the direction in which the lumber is fed under the cutter-head E, on each side of the path of its knives, over the bed of the machine in position to bear upon the boards upon each side thereof. These pressure-fingers are attached to rock-shaft R by collars and set-screws 1- W, by loosening which the fingers may be set higher or lower with relation to the bed. These pressure-fingers of course bear upon the boards on each side of the guide D as the two boards pass through on opposite sides of the guide, as before described.

The bed is formed of a plate, F, which is secured by screw-bolts to the cross-girt f of the frame, and has an opening,f, formed in it, through which the knives of the cutter-head E work in cutting the tongue. This plate or bed F may be removed to givebctter access to the knives of the lower cutter-head.

It will be observed that the pressure-fingers r 1- are capable of independent adjustment to suit different thicknesses of boards being simultaneously worked,'and that they are also adjusted simultaneously with the cutter-head E; also, that the construction of the shafts of the cutter-heads E E and attaching parts so that they project from different sides of the machine gives great facility of access to the working parts for adjustment and in belting to the drivingshaft. For this purpose the pul ley P is attached to the outer end of the shaft 8, and the pulley l? to the outer end of the shaft s outside the maehineframe. The pulley P on the driving-shaft sis belted to the pulley P by a straight belt, and the pulley P on the same shaft is belted to the pulley P by a cross-belt, as shown in Fig. 1. Both the pulleys I P are thus brought closer in toward the frame of the machine than when both of them are located on the same side of the machine and belted to the same shaft 8.

The employment of the presser-finger r between the guides e and D of the machine is especially important in insuring the formation of a tongue on the board which shall fit the groove made by the side cutter-head, C, in a preceding board, because any lifting action of the cutter-heads E E tends to vary the width of the board as well as the shape of the tongue and to draw the board away from the side cutter'head.
