Mor n- RIV N PLANER Application filed October 12, 1925 Serial No. 81,880.

I and for cutting different depths of cuts from the work fed through the machine. The invention is adaptable to the lower cutting cylinder of a planing machine whetl'icr it is a double or single surface machine, the invention being the same in bothcases. In a double surface planer which has two. cutter cylinders, the upper cylinder is usually fixed against aojust-inent vertically while the lower cylinder is adjustable toward the upper cylinder to accommodate work of different thicknesses and to vary the depth of the cut, and in order that the work'sliall be uniform in thickness when it; leaves the machine the two cutter cylinders must remain parallel throughout all positions of adjustment.

is primary object and purpose of the present invention to provide a direct motor drive for thecutting cylinder or cylinders ofplaners, either single or double surface, and to rigid-1y attach said motor in connection with the adjustable cylinder whereby when it is once aligned and secured in place there is no danger of any troubles arising thereafter from poor alignment and poor adjustment which may occur where the motor is adjustable independently of the cutter cylinder. A. further object of the invention is to mount this adjustable cutter cylinder so that it may be bodily moved together with the supporting frame in which it ismounted outwardly, the motor moving therewith; and when in this outerposition but not wholly disconnected from the machine the knives of the cutter may be sharpened or otherwise placed in order.- HereQ tofore it has been the practice universally to disconnect the motor from the cutter cylinder, remove the cylinder from the machine and place it in an'auxiliary frame for the purpose of sharpening or otherwise placing the knives in best cutting condition, This required a re-alignment and reconnection of the motor to the cutting cylinder when it was again placed in the. machine and a readjustment of the motor with respect to the cylinder while the trouble and effort required in moving the cylinder and replacing it and also in placing it in the sharpening frame was great. The present invention obviates all these disadvantages and makes the retouching and sharpening of the cutter knivesin the cuttingcylinder a Very simple and easy proposition.

To these ends and to many others notat this time specifically enumerated we have made the invention described in the follow-' ing description and illustrated in the accompanying drawings, in which,

Like reference characters refer to like parts in the different figures of the drawings.

In the construction of the planing machine, two table carrying members 1 carrying a horizontaltable, 2 at their upper side are formed at their lower sides inclined in a plane at an acute angle to the horizontal as indicated at 3. In practice the members 1 are spaced apart at each side of the machine and the table 2 lies over -and be tween the upper sides thereof. These members 1 bear upon slidably mounted similar members 1 which at their upper edges are formed at an incline and at the smile angle to the horizontal as the sides 3 as indicated at 5. The members a lie one underneath each of the members 1 previously described and by moving the members t horizontally the table and all of the mechanism carried by and in association therewith may be raised or lowered. In practice members 1 are oper ated horizontally through a screw 6 operated by hand wheel 7, the operative con nection of which will later appear.

The members 1 are mounted on the base rails 8 ofthe side members of the stationary frame of the machine, the frame at each side being completed by uprights 9 and 10 which are connected at their upper ends by horizontal rails ll. Guides 12 are mounted vertically one at the outer side of each of the upper members 1 which have slidable hearing against end uprights 9 as shown in Fig. 2, whereby the movement of the table 2 and the supporting members 1 therefor is maintained in vertical directions. The side members of the frame are connected by various cross members, indicated at 18 and 14- in 1 at the opposite ends of the machine there are also suitable cross connecting The and I members between the upper rails 11.

' screw 6 passes through a bearing carried by the cross member 1 1 and through an interiorlythreaded nut15 mounted on a cross bar or rail 15 disposedbetween and. attached at its ends to the oppositely disposed lower members 4. It is evident that by ro-. tating hand wheel 7 the members 41 may be moved inwardly or outwardly with a consequent raising or lowering of the table 2 between the members 1. Back of the feed rollers 16 an upper cutter cylinder 18 is rotatably mounted, it being located above the table 2 and in association with the usual chip breaker device 19 used in machines of this character. An upper roller 20 disposed between the rails 11 lies back of the upper cutter cylinder 18 and d1rectly above a similar lower roller 21 carried by the members 1. Back of the lower roller 21 the lower cut- I ter cylinder 22 is mounted in a novel and very useful manner, the mounting of which will be later described, and which forms a particularly desirable and essential feature of the present invention. An upperroller 23 disposed between the rails 11 and a lower roller 24- located the one above the other are disposed in a plane back of the lower cutter cylinder 22. This is the general outline of the feed and cutter cylinders or rollers in planing machines of this character as shown in Fig. l and the same are shown and described as illustrating the preferred environment of the present invention. It is to be understood, however, that the invention is not limited in any respect to a double surface planer, that is, one having both upper and lower cutter cylinders, but is'also avail able for singlesurface planers'wherein the lower cutter cylinder alone is used.

The lower cutter cylinder 22 is provided with a shaft or spindle 22 extending beyond the cylinder at each end, the same being mounted at each end in suitable bearings carried by the vertical ends 25' of an elongated supporting frame which is completed by spaced apart vertical sides26 and 27 disposed between and either integrally formed with or attached to the ends 25 previously noted. Between the sides. 26 and 2. at desired points integral cross bars may be disposed below the cylinder 22 for the purpose of strengthening. and reinforcing thisframe which carries'tlre cutter cylinder Q 22.. On the side 26 a rack 28-may be-se 1 cured, it being located horizontally near the upper edge of said side 26. I

The elongated frame with'the cutter cylinder mounted therein in turn is mounted in a saddle of channel shape having a base 29 and upwardly extending spaced apart vertical sides 30 and 31. The sides 26 and 27 of the frame lie closely adjacent the inner surfaces of said sides 26 and 27. .A vertical shaft 32 is equipped with a hand wheel at its upper end and is mounted in bearings 3 1 and 35, the former being at-;

tached to one of the rails 11 and the latter .wedge members 3'5.

to the side of the saddle. The bearing is also extended downwardly and formed into a housing or shroud to cover a small gear 36 fixed'to the lower end of shaft 32 and held in mesh with the rack 28. It is evident that a portion of the metal of the side 30 at its upper edge is removed for the reception of rack 28 and also that a slot or recess is cut through the same at its upper edge for the passage of the gear 36 for disengagement with the rack 28. By rotating the hand wheel the cutter cylinder 22 and the frame in which it is mounted may be moved laterally inward or outward depending upon the direction of rotation of the wheel.

'The saddle described is carried at its ends on the upper sides of two wedge members 37 one located at each side of the machine and against the outer sides of the members 1. The wedge members 37 have horizontal upper edges and inclined lower edges, indicated. at 38, which bear upon similarly inclined ledges 39 projecting outwardly from the members 1. Movement of these wedge members 37 effects the raising or lowering of the saddle. Associated with this saddle is the frame or mounting for the adjacent roller 24 so that it moves up or down with the cutter cylinder 22. The vertical movements of this saddle are guided by the guides 39 formed on members 1 (see Fig. 1).

To each of the wedge m bers 37 an interiorly threaded sleeve d0 i cured through which screws ll pass, each having a bearing 42 connected to the outer side of the adja cent member 1. Thescr-ews 41 and the sleeves 4a)- are located at the same angle to the horizontal the lower edges 38 of the i Vorm gears l3 are lined to the lower ends of the shafts ll and are in meshwith worms aid attached to an equalizing shaft 44 which extends horizontally through the machine and which may be manually operated to effect simultaneous movement of the wedge members to; raise or lower the cutter cylinder 22 and the adjacent roller with respect to the table it is evident that the table 2 with all of the rollers and the cutter cylinder 22 associated therewith may be -moved as a. whole vertically to adjust the machine for different thicknesses of stool; which are to be fedv through the machine and it is also evident that by the adjustment of the wedge members the cutter cylinder may be raised or lower-ed to any desired position with respect to the table 2 and in this manner the depth of cut which is to be talren from the stock is governed and controlled.

At one eud'of the elongated frame carrying the lower cutter cylinder 22 an electric motor 1 5 is disposed, from the outer frame of which metal connecting bars 46 and 4'7 e:-:- tend to and are integrally formed with a' to fit a recen after appear. It is evident that the motor moves with the cutter cylinder 22 and its frame at all times in the inward and out ard movements of the same with respect to the remainder of the machine. Normally in the operative position of the cutter cylindcr within the machine the lower side of the frame riding on the bottom 29 of the saddle t the end opposite to that at which the motor is attached comes against a stop 50 (see Fig. which has a pointed inner end made therefor in the end of the cutter cylinder frame mount and said fra no is secured in its inner operative posi tion by a set screw passing upwardly through the bottom 29 of the saddle into the end 25 of the frame shown in Fig. a and as indicated in Fig. 5. All that is required to free the lower cutter cylinder and the motor'for outward movement is to remove the set screw 52 whereupon by rotation of the shaft 32 the cutter cylinder with the attached motor and the fra'an-e carrying the same may be moved outwardly from the position shown in Fig. 4 to that shown in Fig. 5.- i

As thelower cutter cylinder, the frame carrying the same, and the motor secured to the frame are moved outwardly it is desirable to support the free outwardly extending portion to eliminate strains and prevent overbalancing and tilting thereof. To accomplish this a truck is provided, as shown in F i and 5. This truck, preferably, includes an upper casting 53 and a lower casting 5% connected by vertical rods 55 and the lower casting is equipped with rollers so that it may be easily moved over the floor.

A shaft 56 passes through the upper casting and at'its lower end is threaded and eX- tends into and through the lower casting as shown. At the upper end of the shaft a head 5? is mounted shaped at its upper side so as to substantially cradle the lower side of the motor, it fitting snugly and easily into the head. hand wheel with an interiorly threaded hub is mounted on the shaft 56 and rests on the lower casting 54, it being evident that by turning this wheel shaft 56 with the attached head 5'? may be raised or lowered to desired position. The truck is placed underneath the motor 45 and the shaft adjusted upwardly so that the head ts against the under side of the motor and then with the outward movement of the motor the truck moves therewith supporting the same and holding the cutter cylinder and the frame in which it is mounted substantially horizontal.

On the end of the elongated frame supporting the cutter cylinder 22 a bracket 59 is permanently secured projecting from which is a member 60 divided atits end adjacent the motor so as to provide two spaced apart fingers. A bar (31 is guided between these fingers and at its lower end is formed into a fork having two. downwardly extending arms 62 which are adapted to pats one at each side of the shaft 22 and inside of the bars 4E7. A pin 63 extends from the bar Gland is adapted to be received in any one of the recesses or radial groo es d9? inthe disk 49 previously described. A turn button 64 is pivotally mounted in a horizontal position on the bracket 59 and may be turned. so as to bear against the upper end of the bar 61 and hold the same against accidental displacement. This structure is used when, at times, the cutter cylinder is to be held against rotation in sharpening and retouching the cutter, knives thereof.

l/Vhen the cutter cylinder '3 ms been projected outwardly to the position shown in Fig. 5, a frame-for carrying the s. rpening devices is adapted to be connected to the sup porting frame for the cylinder. It consists of two brackets 65 shaped to fit over the ends of the cutter cylinder frame and adapter to be securely held in place by set screws 66 as shown in Fig. 7. Arms 67 extenl from the brackets to one side and then upwardly and between the upper ends of these arms a bar 68, trapezoidal in section, is located and permanently secured. each end thereof stop members 69, best shown in Fig. 7, may be adjustably mounted and retained in any desired position by set screws from which pins 70 extend toward each other, being for the purpose of limiting the travel of the sharpening devices which may be mounted on the bar 68. In the first operation of sharpening the knives the cylinder 22 is left free to rotate and is rotated by the motor i k so-called jointing" device is mounted on the bar 68 and may be moved back and forth thereon, an abrasive stone or similar member being fed toward the knives which coming in contact therewith are inv this manner, with the cutter l ead rotating, all cut down to the same height. The construction of the jointing device comprises a slide 71 mounted on the bar 68 from which a rod 72 ads outward having a handle formed at its outer enifl that the slide may be moved manually back and forth on the bar 68. A plate 73 is adjustably mounted on the slide 71 on the face of which the jointing tool may be detachably secured this cou'iprising a base 74 fitting in and detachably connected On this bar adjacent to the plate 73, an arm 75 extending therefrounand a stone or similar abrasive member 76 fixed at the freeend of the arm 75.

The stone is positioned vertically and so 10- cated that it lies substantially in a vertical plane containing the axis of the cutter cylindcr (see Fig. 6). The stone may be fed toward the knives by rotating the crank 77 shown. This construction of jointing too]. is not any part of this invention and specific details of the structure thereof need not be entered into.

After the jointing operation has been performed the jointing tool is removed from the bar 68 and a grinding wheel driven by an electric motor slidably mounted thereon in any suitable manner in accordance with old and accepted practice. Vi henthis is done the bar 61 with its projecting pin 63 is mounted in place and is successively engaged with the radially disposed grooves 49* in the disk ll} as shown in Fig. 8. There being as many of these grooves as there are knives in the cutter cylinder each knife may be sharpened by the motor as is evident.

Y is evident from the foregoing that many advantages are inherent in this construction when applied to planers. The adjustment of the table for different thicknesses of stock carries the motor 45 withit and the adjustment of the cutter cylinder 22 for difierent depths of cut carries the motor with it, it at all times being aligned with the cylinder and there is no possibility or likelihood of any misaligm ent occurring as in other structures where the motor has to be disconnected from the cutter cylinder whenever the same is removed for sharpening the knives. direct and permanent connection of the motor is a very valuable and practical feature of this invention.

The

The possibility of theoutward projection of the cuttercylinder whenever itrequires attention and the knives need dressing or sharpening without requirmg its removal bodily from the machine, and

the simple and efficient mechanism by which it is projected is another exceedingly valuable feature of the invention. W'here the cutter cyhnder has been removed heretofore it has'not only-necessitated some form of coupling'between the motor shaft and the cutter cylinder, which coupling had to be detachable so that the motor could be shift d out of the way, but the cylinder being heavy and cumbersome it was necessary for at least two men to take care of the removal-and the replacement of the cylinder. The cutter cylinder had to be carried to a suitable auxiliary sharpening and grinding device and placed therein, thus requiring separate and distinct machine which owners of planers of this character were required to keep in op eratien at their plants. All of this trouble and effort is obviated by the present invention. The cylinder does not have to be reiso moved. One man can att nd to the projection thereof or the retraction into thebody of the machine and the-supporting frame consisting of the bracket 65, arms 67 and bar '68 may be easily placed on to and taken off when necessary. The invention is defined in the appended claims and is to be considered as comprehensive ofall forms of structure coming within their scope.
