SOLOMON A. VOODS AND JOHN R. THOMAS, OFBOSTON, MASSACHUSETTS, ASSIGNORS TO THE S. A. WOODS MACHINE COBIPAW'NY, OF MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 39.1..;i, dated October 91 1888- To all whom it may concern.:

Re it known that we, SOLOMON A. Woonsand JOHN R. THOMAS, both of Boston, in the count-.y of Suffolk and State of Massachusetts,

have invented a certain new and useful Improvement in Uprightllatching-Machines, of which the following is a specification.

Our improvement relates to machines for tonguing and grooving or dressing the edges v 1o of lumber; and it consists in certain new and useful constructions and combinations of the various parts thereof, substantially as hereinafter described and claimed.

The machine to which our improvements are applicable is what is known as an upright matcher7-i. c., one in which the lumber passes between vertical feed-rolls over a revolving cutter, which tongues, grooves, or reduces the edge of the lumber,such cutter being 2o mounted upon a horizontal spindle.

In the drawings, Figure 1 is aside elevation of an upright matching-machine constructed according to our invention. Fig. 2 is a top plan view ofthe same. Fig. 3 is an end view 2 5 of the same. Fig. 4 is a transverse vertical section on the dotted line A B of Figs. 1 and 2. Fig. 5 is an enlarged detail plan View of a portion of the machine-bed and attached parts over one of the tonguing-cutters. Fig. 6 is a 3o side elevation of the same. Fig. 7 is a transverse vertical section of the same on the dotted line a b of Figs. 5 and 6. Figs. 8 and 9 are respectively enlarged plan and edge views of the train of gears used to drive the feedrollers ofthe machine. Fig. 1() is an enlarged vertical section of a portion of the same.

The frame 1 of the machine supports the table and operating parts. The bed 2 is mounted on top of the frame and consists of 4o two separate strips or plates--one for each 1natcher`l1ead-as Shown.

It is necessary in these machines to have a cutter-head, 3, for grooving, and another, 4, for tonguing, the edge of the board. Cutterhead 3 is mounted upon the shaft 5, extending transversely across the frame, upon which it is mounted in boxes, and the shaft is provided with the pulley 6, by which it is driven from a countershaft. Cutter-head 4 is provided of line with chine,'inste t, the same shaft, as. n

Upon each side c cated a pair of vertical the former on the feedf of vertical feed-rolls,11 and naare pla y side ofthe cutter-head 4. The ci ,-c y rolls 10, being the feed-Out rolls of cutter er 3, are placed in line transversely of with the pair of feed-in rolls 11 of the c head 4, which arrangement brings the fees; rolls of the former cutter-head in advance all others transversely ofthe table and offsets the location of the feed-rolls of cutter-heads 3 and 4, so to speak. By means of this arrangement the operator, standing upon the sidevof 7o the machine shown in Fig. 1 and in advance of the feed-rolls 11, is enabled to reach over and take the board as it comes from either feed-out rolls 10 10 or 12 12 without stepping away from his position for feeding boardsin to either head. He can, therefore, handle the stock faster and with less fatigue. For instance, suppose 3 to be the grooving-cutter and 4 the tonguing. The operator rst feeds the short piece of board through the rolls 9 10, 8o and,seizing it as it comes from thelatter,turns the other edge downward and feeds it through the rolls 11 12. rlhis grooves one edge and tongues the other ready to be joined to the next board. g '85 In order to arrange the feedrollers 9 10 and 11 12 as'described, it has been found necessary to devise a new train of gearing to drive them and allow one of each pair to yield to varyirig-\` thicknesses of boards. roller of each pair is mounted in a long sleeve, 13, attached to the frame 1 rigidly. Each of these shafts carries a driving-gear at its lower end. The outer feed-roller of each pair is also mounted in along sleeve, 14, and this sleeve is swung or pivoted to an upright post, 15, Fig. 1, by arms 16 16. The upright post 15 consists of a central rod fixed solidly in the The shaft of the inside 9\` the shank being somewhat smaller than the hole. The screw end of this br 1 is tapped through an ear, 20, fixed to une. A collar, 21, is slipped over th u1" the bolt and slides thereon .13, and a spiral springe` l Seli shafts are pro ...rita they are driven, l it; the outer ones to yield, wl.: being driven they are ar- ,lnlcwm On shaft 7 is attached the i a hich is belted to pulley on shaft t .i the outerend ofthelatter is the double t pulley 27. This is belted to the doublepart pulley 28 on shaft 29. These pulleys are made with double parts in order that the belt may be used either from the larger part of pulley 27 to the smaller part of pulley 28 or vice versa to run the feed-rollers at different speeds. On the outer end of shaft 29 is attached the pinion 30, which gears into the gearwheel 31 ou shaft 32. The latter shaft carries the bevel -wheel 33, which meshes into the bevel-gear 34 on the lower end of the shaft of the inside feed-roll 10. Above this bevel-gear the pinion 35 and larger gear-wheel, 36, are attached to the same shaft.

The gear-wheel 36 drives the feed-rolls of the cutter-head on theside of the machine shown in Fig. l as follows: It engages with gear 37 on the lower end of the shaft ofthe inner feed-roll 11. Below the gear 37 the pinion 38 is attached to the same shaft. It engages with the gear-wheel 39, which drives the pinion 40 Qathe lower end of the shaft of the innegteed-roll 12. Gear 39 also engages with/.gear 41, which engages with the pinion 42 on the lower end of the shaft of the outer feed-roll 1l, and also engages with the pinion 43 on the lower end of the shaft of the outer feed-roll 12. 'The axis of gear-wheel 41 is directly beneath the center of the post 15, on which the shafts of the outer feed-rolls 11 and 12 are pivoted, as before described. Vhenever,therefore, these feedrolls yield to different widths of lumber, their centers and those of their shaft- pinions 42 and 43 swing outward in an are concentric with gear-wheel 41, thus keeping these pinions in mesh with this gear-wheel,

which drives them to the sameextent at all times. ,l

Referring now to pinion 35,which drives the feed-rolls of cutter-head 3 on the opposite side of the machine, it engages with gear-wheel 44, which in turn drives the pinion 45 upon the lower endof the shaft of the inner feed-roll 9. Gear-wheel 44 also engages with gearwheel 46, which drives pinion 47 upon the lower end of the shaft of outer feed-roll 9. and also drives pinion 43 on the lower end ot' the shaft of outer feed-roll 10. It will be oloserved that the centers of' the pinions 47 and 48 of the outer feedrolls 9 and 10 swing outward as the feed-rolls yield in arc concentric with their driving-gear 46, they being huugin the same manner the outer feed rolls 1t and 12, as before described.

The pulleys 6 and S ofthe two cutter-head shafts are offset, as shown in Figs. 2 and 3, so that they may be driven from the same counter-shaft, and the cutter-heads are respectively applied to the other ends of the shafts 5 and 7, carrying these pulleys, which enables the cutterheads to be removed through the space between the sleeves 13 and 14, carrying the feed -roll shafts,without distu rbingthefeedrolls. For this purpose these sleeves are cut away slightly, as shown in Fig. 1, in arcs concentric with the center of the cutter -head spindle, which enables us to introduce alarger cutter-head through this space.

The cutter-heads are held onto the ends ot' their shafts by nuts 50, clamping them between collars 51, as shown in Figs. 1 and 4,and they can thus be both readily removed and replaced in a manner which would not be practicable if they were placed in line with each other transversely of the machine, as has heretofore been customary. The inandrels of these cutter-heads may also be adjusted independ ICO ently of each other longitudinally in their l boxes, which was not possible when they were both mounted upon the same mandrel.

Each bed-piece 2 carries upon it a vertical guide-strip, 52, which is attached to it by ears 53 (shown in Figs. 5, 6, and 7) and bolts passing down through the said ears into the bed-piece 2. This guide-strip aids in directing the lumber properly between the feed-rolls. The guidestrips are cutaway, as shown in Figs. 5 and 6, where the inside feedrolls revolve, toallow the lumber to bear against the latter. The cutterheads work through the bed-pieces 2, an aperture, 54, being formed in the bedpieces for'this purpose.

When used with the tonguing-cutters, we supply the bed-piece with a bridge, 55, which divides the aperture 54 longitudinally, the knives of the cutter coming up each side of the bridge th rough the aperture.

Directly opposite to the guide-strip 52 and the matcher'eutter we attach to the bed-piece 2 an elastic pressure-strip. 56, to hold the lumber accurately against the guide-strip 52 at the point where the tongue or groove is formed in its edge. The guidestrip 56 has attached IIO to its rear side the bolts 57 by means of pivots 58. These bolts pass through the block 59 and have nuts 60 on their free ends behind the block to limit their forward movement toward the cutter-head. Between the block and the pressure-strip 56 the spiral springs 61 are placed around the bolts, pressing thestrip 56 toward the opposite guide-strip, 52, and thus compressing the lumber as it passes over the matcher-cutter. The forward movement of the pressure-strip 56 is limited at pleasure by the nut 60. The block 59 is secured to the bed 2 ofthe machine by the screw-bolt 62, passing through an elongated slot, 63, in the block, and having its head overlapping the sides of the slot, and being tapped into the bed at its screw-end, asshown. rlhis construction not only allows the pressure-strip 56 to yield directly backward, but allows one end to yield more than the other to the incomingl lumber until the board has passed fairly between the entire strip and the guide 52.

Each of the spindles 5 and 7 is made adjustable longitudinally to bring the cutter head to the proper position with relation to its feed-rollers by similar means. Thus the boxes of the spindles 5 and 7 are secured to plates 7 0 and 7l,which slide on guideways on the cross-girts of the frame 72 72, these plates being connected together by a yoke, 73. From the plate an ear, 74, projects downward, in which the screw 75 is attached through a hole, so as to revolve and carry the ear with it. The thread end of this screw engages with the ear 76, attached to the frame, by passing through a threaded hole in it. When the screw 75 is turned, therefore, it moves the boxes and spindle of the cutter-head longitudinally ofthe latter to its proper position.

Both of the screws 75 75 project outward upon the same side of the machine, and the adjustment of the cutter-head shafts 5 and 7 can therefore be performed on that same side thereof.

What we claim as new and of ourinvention is v l. The combination, in a wood-planing machine adapted to dress the opposite edges of the same board by successive operations, of two cutter-heads, 3 4, mounted on horizontal spindles, and a pair of upright feed-rollersbefore and behind each head with the feed-in rollers of one cutter-head located nearer to the feed-in end of the machine than the feed-in rollers of the other cutter-head, substantially as described.
