PLANER Application filed. July 9,

To all whom t may Gomera.'

Be it known that I, JAMES 1. MUNDELL, a citizen of the United States, residing at Groton, in the county of New London and State of Connecticut, have invented a new and useful Planer Machine, of which the following is a specification.'

rlhis invention aims to provide a planer mechanism carrying clapper blocks, so mounted that the tool in one block will operate when the work is moved in one direction, the tool in the other block operating when the work moves in an opposite direction, the planer cutting thus on both strokes. Another object of the invention is to provide novel means for feeding the tools in various directions with respect to the work.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of theinvention shown can be made without departing from the spirit of the invent-ion.

n the drawings:

vFigure 1 shows in horizontal section, a portion of a planer embodying the present improvements, parts being broken away; Figure 2 is an elevation showing a portion of the vertically adjustable frame which moves on the housing; Figure 3 is a section on the line 3 3 of Figure 1; Figure 4 is a section on the line Z--4 of Figure 1. Figure 5 is a plan showing the driving mechanism for the planer table; Figure 6 is an elevation of the driving mechanism for the planer table.

The numeral 1 marks the vertical posts whichconstitute a part of the'housing of planer. rlhe numeral 2 designates, generally a frame mounted for vertical adjustment on the posts 1, the frame embodying side members 3 and 4, end members 5 and 6, and an intermediate member 7 extended between the members 3 and 4. The side members 5 and 6 are equipped with lugs 8 eX- tended into the posts 1 and engaged by screws 9, constituting part of any standard or desirable mechanism whereby the frame 2 192e. sei-iai no. 650,396.

considered as an entity, may be raised and lowered. In order to hold the frame 2 in any position to which it may have been adjusted vertically on the posts 2 a. wedgeshaped key 10 is held for llongitudinal reciprocation on the intermediate member 7, and is adapted to be advanced and retracted through the instrumentality of a screw 11, mounted-for rotation but against endwise movement in the side member 4, the inner end of the screw being threaded into the key 10 and the key being interposed between the intermediate member 7 and certain of the posts 1 as shown best in Figure 1 of the drawings.

A slide 12 is mounted for'horizontal reciprocation on the intermediate member 7 and a slide 14 is mounted for horizontal re ciprocation on the end member 6 of the frame 2. As shown in Figure 3 a horizontal shaft 15 is mounted. to rotate in the slide 14, a stud 16 being mounted in the slide 12 in axial alinen'ient with the shaft 15. A guide 17 is mounted to tilt for adjusti'nent on the stud 16, and a guide 18 is mounted to tilt for adjustment on the shaft 15. A carrier 19 is vertically adjustable inthe guides 17 and 18, A post 2O is held in the carrier 19 clapper blocks 21 being pivoted at 22 upon opposite sides of the post 2Or at the lower end thereof, the clapper blocks carry ing` cutters 23, the construction being such, as Yindicated in Figure 3, that when the work moves in on-e direction, one of the tools will cut and the other tool will drag, whereas, when the direction of movement of the work is reversed, that tool which 'formerly was active, will become the dragging tool, whereas Vthe tool which formerly dragged, will do ther cutting. 'The result is that a cutting is brought about upon each stroke of the work, as the work is carried backwardly and forwardly on the movabletable of the planer.

A shaft 24 is ournaled for rotation in the frame 2 and extends lengthwise of the interminate member 7, the shaft being threaded into a projection 25 on the slide 12, as shown in Figure 3. rllhrough the instrumentality of intermeshing beveled pinions 26, shown in lFigure 1, the shaft 24 is connected operatively with a shaft 27 mounted to rotate on the side member 8. There is a beveled pinion 28 on the shaft 27, the same meshing with a beveled pinion 29 journaled on the member 3 of the frame 2, a pinion 30 being mounted to rotate with the beveled pinion 29. The pinion 30 meshes with a gear Wheel 31 on a shaft 32 journaled on the frame 2 and extended lengthwise of the end member 6, the shaft 82 being threaded into the lug 38 on the slide 14. A ratchet gear 33, common in planers, is adapted to be mounted on the projecting end of the shaft 32 and meshes with a gear Wheel 84 carried by a. shaft 35 journaled in the member 3. A. shaft 35 carries a pinion 36 cooperating With a rack bar 3'? which is a ltnoivn part of a common feeding mechanism in planers.

rlhe rack bar 37 rotates the pinion 36, the pinion 36 rotates the shaft 35, from the shaft 35 rotation is imparted to the gear Wheel 34, the gear Wheel 34, cooperating with the ratchet gear 33, rotates the shaft 32, from the shaft rotation is imparted by the gear Wheel 31 to the gear Wheel 80, the gear Wheel 30 rotating the beveled pin ion 29, the beveled pinion 29 driving the shaft 27 by Way of the beveled pinion 28 and rotation being imparted to the shaft 24 by Way of thebeveled pinions 26. Recalling that the shaft 24 is threaded into the lug 25 on the slide 12 vand that the shaft 32 is threaded into the lug 38 on the slide 14, it `vill be obvious that a means is provided whereby the tools 23 may be adjusted transversely of the line in which the Work is being reciprocated.

The shaft 35 carries a gear Wheel 39, meshing with a gear Wheel 40 journaled on the member 3. A beveled pinion 41 is mounted to move with the gear Wheel 40 and Y meshes With a beveled pinion 42 on a shaft 43 journaled in the member 3 of the frame 2 and located parallelto the shaft 27. On the inner end of the shaft 43 there is a beveled pinion 44 meshing with a beveled pinion 45 mounted to rotate with gear Wheel 46 journaled on the member 3, the gear wheel 46 meshing with a gear Wheel 47 on a shaft 48 journaled in the membery 3, the shaft 48 carryinga gear Wheel 49. The gear Wheel 49 meshes with a ratchet gear 50 of the sort hereinbefore alluded to, the ratchetA gear 50 being" adapted to be mounted on a shaft lkconnected by any suitable mechanism of common and known construction. including beveled pinions 2, with a. tool holder 53, to secure avertical adjustment of the tool holder, the tool holder being mounted to reciprocate on a slide 54 carried by the member 5 of the frame v2. In the member 5 lis journaled a. shaft 55 threaded into a lug 56 on the slide 54. The ratchet gear 50 may be shifted to the shaft 55 when it is desired to secure a reciprocation of the slide 54 on the member 5 longitudinally thereof.

At the Will of an operator the ratchet gear may be shifted from the shaft 32 to a shaft 57 journaled in the member 6 of the frame 2 and extended longitudinally thereof. A beveled pinion 58'is splined to the shaft 57 to slide therealong at the will of an operator and is under the control of a lever 59, ful'crumed at 69 on thc slide 14 and having an opening 61, adapted to be engaged with pins 62 on the slide 14, to hold the lever 59 in adjusted positions, the lever constituting means for shifting the beveled pinion 58 into and out of mesh lwith a beveled pinion 63 on the shaft 15, the shaft 15 being equipped at its inner end with a` beveled pinion 64 meshing` with a beveled pinion 65 held for rotation on the guide 18, a screw 66 beingthreaded into the iinion 65 and being held against longitudinal movement on the carrier 19. The scren7 66 may be held against rotation, at the Will of an operator, by a latch mechanism 67 of any desired construction. When the shaft 5.7 is rotated, rotation Will be imparted to the shaft 15 by the beveled pinions 58 and 63, it being possible to disengage the pinions when the pinion 58 is moved tl'irough the instrumentality of the lever 59. l/Vhen the shaft 15 is rotated, the pinion 65 Will be rotated from the pinion 64, and the screw 66 Will be caused to move verically, thereby adjusting the carrier 19 and the tools 23 vertically. lh'en the pinion 58 is disengaged from the pinion 63, the screw 66 may be rotated by hand to effect a raising and lowering of the carrier 19 and the tools 23.

rEhe device hereinbefore described is relatively simple in operation, and the fnnctions of the various parts have been set hereinbefore. 1t will be seen. however, that lthe tools 23 cut in oppositie directions when the worlr is reciprocated and that it is'possibel to adjust the tools in various Ways with respect to the Work.

fr. Figures 5 and 6, a mechanism foroperating the planer table is shown. ln those figures, there appears a reversibly driven drive shaft carrying a loose gear 81 and a fixed pinion 82, the pinion meshing With a gear 83 on a shaft 84 carrying pinion 85 which meshes With the `gear 81, the pinion 85 meshing with a gear 86 on a shaft 87 carrying pinion 88 meshing with a gear 89 on a shaft 90. The gear 81 meshes with a pinion 92 cn a shaft 91, the pinion 92 meshing With gear 93 on a shaft 94 carrying a pinion 95 meshing ivith a `gear 96 on a shaft 97. The raclr bar of the planer table is marked by the numeral 98 and engages with the gears 89 and 96, rotation being imparted to the gears 89 and 96 'from the reversibly driven shaft 80, and longitudinal reciprocation being imparted to, the rack bar 98 and to the planer table from the gears 89 and 96.

That is claimed is:

In a device of the class described, pairs of posts, a frame mounted for vertical ad iustment on the posts and means for adjusting the frame vertically on the posts, the framev comprising a first end member engaging the outer edges of the posts of one pair, a second end member engaging the inner edges of the posts oi: tlie other pair, an intermediate member disposed parallel to the end members and located between the pairs of posts, and side members loeatedv.,

outwardly oi the posts and connecting the extremities of the end and intermediate members; slides mounted for adjustment along the intermediate member and along` the second side member guides mounted to tilt for adjustment on the slides, a carrier adjustable vertically in the guides and including a post, and clapper blocks located at the lower end of the post and pivoted to opposite sides of the post, the post constitutiing,` an abutment for eacli clapper block when tlie same is in Working position.

In testimony that I claim the foregoing as my own, l have hereto atlixed my signature 20 in the presence of two witnesses.
