PLANING AND MATCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 463,577, dated November 17, 1891.

Application filed January 14, 1889. Serial No. 296,256. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM H. .DOANE, a citizen of the United States, residing at Oincinnati, Ohio, have invented new and useful Improvements in Planing and Matching Machines, of which the following is a specification.

My invention relates to planing and matchin g machines, its object being to facilitate adjustment and manipulation of the parts and secure a more perfect coaction between the same, so as to improve the quality of the work done, and, generally, to economize labor in the manipulation of the machine and promote rapidity of action.

To this end my invention consists, generally, first, in a substantially continuous movable guide or fence extending from the feedingin to the feeding-out end of the machine at the right side, provided with ad justing devices, whereby the same may be shifted as an entirety to utilize the entire width of 'the cutter-cylinders by shifting from dulled Zones to unused parts, thus avoiding the necessity of too frequent removal of the cuttingknives for regrinding or changing and constructed with an adjustable face-section to obtain nicer final adjustments independently of the shifting mechanism; second, in the construction and arrangement of the fence-shifting shaft and its connections, tending to facilitate the adjustment of the fence without interfering with the removal of the lower cutting-cylinder; third, in the construction of the fence or board guide, whereby the guiding-face is susceptible of a minor adjustment across the platen independently of the general shifting devices; fourth,in the construction and arrangement of an auxiliary and independently-adjustable feed-out fence at the left side of the machine; fifth, in the combination, with said auxiliary feed-out fence, of connections with the main fence and its shifting mechanism for simultaneously operating both fences in fixed relations when desired; sixth, in the construction of said auxiliary fence and its adjusting devices in relation to its matcher-head, whereby the auxiliary fence and its matcher-head may be adjusted together in relationto the opposite or main fence independently of or by coupling to the main fence-shifting mechanism, or the auxiliary fence may be independently adjusted in relation to its matcher-head to compensate variation in width of lumber occasioned by wear of the cutter-bits or other causes; also, in the construction of the auxiliary fence with supplemental adjusting features for finer ultimate adjustments without changing its general position or relations with its matcherhead or the opposite fence; seventh, in the provision and arrangement of a locking device for securing the opposite matcher-heads permanentlyin adjusted relations; eighth, in the combination of an adjustable feed-in fence with an adjustable side or edge feed -roll, either capable of being moved toward the other across the bed of the machine; ninth, in the combination, with the surfacingcylinders, watcher-heads, and-fences, of a presserbar for the lower cylinder carried upon an extension of the upper cylinder-housing and adjustable therewith, and, lastly, in certain other features of constructive detail, as hereinafter described, and pointed out in the claims.

Mechanism embodying -my invention is illustratedin the accompanying drawings,.in which Figure 1 is a left or working side elevation of a planing and matching machine to which my invention is applied, details and connections of parts not immediately concerned being omitted for clearness of illustration; Fig. 2, a plan View of the machine; Fig. 3, a detail end view of the matcher-hangers, showing the gears and screw connection with .the guide-moving shafh- Fig. 4 is a detail plan and end elevation of the adjustable connecting devices for operating the matcherhangers simultaneously or independently; Fig. 5, an end view of the machine, partly sectioned, showing construction of the feedout fences and their adjusting mechanism; Fig. 6, an end View ofthe right guide at the feed-in end of the machine; Fig. 7, an end view of the feed-out guide; Fig. 8, a detail plan showing a modified form of the adjustable feed-out guide, in which the connection with the matcher-hanger is omitted; Figs. 9, 10, andll, detail plan elevation and section, on a slightly enlarged scale, of the parts shown in Fig. 8; Figs. 12 and 13, a detail side view and plan, respectively, of the locking device for the matcher-adjusting screws; Fig. 14, a:

detail side view showing the construction and arrangement of the fence-moving shaft and spiral-gear connections; Fig. 15, a plan detail of the upper cylinder-housing frame with resser-bar overhung thereon.

Referring now more particularly to the drawings, A designates the main frame or supporting-bed of the machine, which, in the machine to which my invention is applied,is made of liberal width to accommodate longer cylinders, in order to allow for shifting the board to new cutting portions of the cutters as the used zones become worn. This is done to economize the labor and time of removing cutter-blades for sharpening, as well as to accommodate the lumber of varying widths.

A designates the upper cylinder-housing frame; A the upper cylinder and bearing; A", the lower cylinder and bearing; A", the presser-bar over the lower cylinder; A A, matcher-hangers carrying matcherheads mounted on vertical cross-bars, and A A cross-bars before and after the cut of the lower cylinder.

13 B B designate the roll-stands; B B B, the lower rollers, and O O C the upper rollers. The lower rollers are connected by a train of gears C C C, and the upper rollers are driven by expansion-gearing. (Not shown.)

The feed-in platen D, Fig. 2, carries a side or edge feed-roll D, fitted rigidly to a pintle carried vertically in hearings in a slide-frame D gibbed to the under side of the platen, said pintle carrying at its lower end a bevelgear D The frame D is formed with a downward ly-proj ectin g yoke D, embracing the hub of the bevel-gear D carried in a pin-andfeather sliding engagement upon a drivingshaft 1), journaled across the bed A, beneath the slideway of the roll D. The yoke holds the bevel-gears D and D in constant engagement while permitting the sliding of the rollframe and the roll across the bed. This side movement is eifected by a screw-shaft D journaled in the bed A, adjacent to the driving-shaft D threaded through a projection of the bearing-frame D and carrying a handwheel at its outer extremity. A coiled spring D is placed upon the screw-shaft D bearin g from the bed A against a collar upon said shaft to permit an automatic receding adj ustment of the roll D to accommodate the varying width of lumber fed through the machine.

The feed-roll just described operates the lumber in connection with the opposite fence or guide F, which extends from the feed-in end of the machine to the matcher-hangerA and thence by an extension I 1 throughout the entire length of the machine across the feed-out rolls B C and feed-out platen E.

The integral adj ustability of the entire fence and right matcher-head is accomplished by a shaft II, journaled at the right side of the bed A longitudinally, and provided with spiral gears H, placed opposite slotted open ings F in the platens across the bed of the machine. Beneath and parallel with these slotted openings are journaled cross-screw shafts F pro vidcd externally with correspon ding spiral gears G, meshing with the gears II, respectively. The screw-shafts F at the feedin end of the machine, Fig. 6, engage with angle-blocks F, having flat upper faces and vertical extensions projecting downward through the openings, as guides F The fence F rests upon the upper faces of the angle-blocks, the bolts for securi ng the fence thereto being elongated laterally in the faces of the angle-blocks, whereby the fence F has an adjustment upon the angle-blocks independent of the screw shafts by loosening and resetting the fastening-bolts F The feed-in fence is adjustably attached to the matcher-hanger A, which intervenes between the feed-in and feed-out portions of the fence, the fence F being slotted crosswise at F where it is bolted to the hanger A, and is provided with a backing-screw F for the nice adjustment of the fence in relation to the sweep of the matcher-hanger cutters, as to accommodate wear in the cutting-surfaces. The principal object of these adjustments is to give the fence lead when requisite independently of its general shifting adjnst1nent-that is, vary its angle slightly in relation to the feed-in rolls so as to crowd the lumber sufliciently to insure absolute fixedness of lateral position while being operated on by the cylinders.

The rear or feed'out portion of the fence, designated in the drawings at I, may be pivoted to and connected across the lower cylinderA by a removable bridge continuation .1, extending into a guide-block 1 at the matcher-hanger A, which has a slotted bolthole connection to the matcher-hangerA, similar to F but without a backing-screw. At the rear terminal cross-adjustin g screw-shaft F, the part I has the described slotted connection for sidewise adjustment upon its an gle-block I and is further provided with a backing-screw and hand-wheel 1 Fig. 5.

The fence I is madein two partsthat is to say, an intervening plate orcarrier 1 ha-ving the described adjustable bolt-connection, with the angle-block I and with an upward lug carrying the backing-screw and hand-wheel I and the fence proper I, independently adjustable upon the plate by means of the backing-screw. The object of these adjusting constructions is to provide not only for a general or permanent adjustment of the fence, but also for the smaller and nicer individual adjustments in relation to the matcher-head independently of the general shifting of the fence as a whole to regulate the draft of the boardin feeding-out according to varying con ditions.

To accommodate the last-described or supplemental adjustment of the fence I upon its plate 1 the fence is provided with laterallyelongated bolt-holes to accommodate the fastening-bolts 1 which, in connection with the backing-screw, serve as guides to preserve its IIO parallelism, besides clamping-bolts to secure it in ultimate positions upon the plate I Thus independently of the shifting move ment (for determining the position of the board relative to the cutting-zones of the cylinders) a permanent adjustment of the fence in relation to the matcher-he'ad may be approximately made by adjusting the plate I upon the angle-blocks I and a finer and more exact adjustment is effected by the handscrew 1 moving the fence I upon its plate I from time to time as required.

The matcher-hanger A is gibbed to the bed A to slide across, as impelled by a screw-shaft H which also has a screw-gear connection G 11' with the shaft H. (The shaft H is in this case extended across and beyond the bed for connections presently to be described.) Thus thefence F, its extension I, and the matcherhanger A are all geared similarly to the shaft H and moved in unison by it. The shaft H, however, is in two portions, the main portion I-I extending above the screw-gears G as far aft as the gear for the matcher-hangerA and the rear portion H extending thence in a lower horizontal plane beneath the under cutting-cylinders. The spiral gear G of the matcher-hanger screw H is the connecting medium of power between the two portions of the shaft. This construction places the rear extension of the shaft below the bearings of the under cutting-cylinder A and permits the removal of the latter without disconnecting the shaft or any portion or disturbing other parts, besides avoiding the interference with the free discharge of chippings from the matcher-head. The shaft being at the rightor fence side of the machine; the shiftingscrews are comparatively short and require but one bearing, and the manipulating end of the shaft being at the feeding-in end and above the level of the screw-moving gears is thus brought to about the level of the fence itself and arranged in a position most eonvenient for, operation by the attendant with reference to the fence-gage on the bed of the machine at the feed-in end. He can thus manipulate the fence with great ease and accuracy not otherwise attainable. The construction of the shaft in sections, and the directness of the connections with the screwmoving gears is also advantageous in avoid ing the constructive difficulties incident .to a single long shaft and the liability to lost motion from torsion and wear of intervening parts.

The matcher-hanger A (corresponding and opposite to A) is similarly mounted upon the bed A in sliding bearings and adjusted by a screw-shaft K, Fig. 3, beneath and parallel with the screw-shaft H It may carry a guideblock extension J, extending rearward over the feed-out cylinder A (corresponding with the bridge I of matcher-hanger A The guide J moves with the matcher-hanger A, to which it is ad justably attached by a slotted bolt-hole connection, permittingit to be set to accommodate wear of the cutters and to guide the lumber properly and firmlywhile acted upon by the under cutting-cylinder to its engagement with the final feed-out guides.

I also provide a feed-out guide J, extending over the rear feed-out roll B. It is practically an opposite duplicate in construction of the feed-out fence I, already described, to which it may be considered as auxiliary, and embraces a screw-shaft J arranged beneath the rear screw-shaft F Fig. 4. It is also provided with a backing-screw and hand-wheel J all these being counterparts of those already described and designated by the letter J, instead of I, with corresponding distinguishing numbers, and'situated on the other side of the feed-out platen. The screw-shaft J 2 mayhave a detachable connection by movable bevelgear J 6 with gearsJ K K and counter-shaft K with the screw-shaft K whereby the gen-.- eral adjustment of the part J may be made simultaneous with the setting-up or receding of the matcher-hanger A". The screw-shaft H as already mentioned, is extended through a bearing at the front or working side of the machine, and the two screw-shafts H K are provided, Figs. 1, 2, 12, and 13, with a yokep'late M, in which operates a block M fitted to both screws and set up or allowed to recede by a cam hand-lever M, by means of which construction the two matcher -hangers are lockedin position when suitably adjusted.

To secure the simultaneous shifting of the two watcher-heads and their guide from the actuatingshaft H, I provide at the projecting terminals of the screw-shafts H IQ, at the working side of the machine, spur-gears P P permanently connected to said shafts, and arrange between them an idler spur-gear P up-. on an elongated stud upon the yokesplate M, which permits the lateral withdrawal of the connecting-idlerfrom such connection. When in connecting position,the motion of the screw-. shaft H is transmitted to the screw-shaft K and by the counter-shaft- K to the screw-shaft J thus moving the auxiliary feed-out guide J and matcher-hanger A simultaneously with the general fence and matcher-head at .the opposite side of the machine. Thus the entire system of fences and matcher-heads may Y be shifted across the bed of the machine simultaneously and at a single operation in exact maintenance of their permanent relations, while by drawing out the idler-pinion P the left feed-out fence and matcher-head I gated bolt-holes L in the fence J forthe passage of fastening-bolts L, by which the fence 5 when adjusted is clamped to the platen. The

fence J is held to its plate J by bolts J passing,through elongated bolt-holes. The extra adjustment of the guide J upon the surface of the plate J is effected, as before described, by the hand-wheel J In addition to the improvements thus detailed I introduce a further one in respect to the construction and mounting of the presserbar over the under cutting-cylinder with the object of facilitating the removal of said cylinder when necessary. To this end I extend forward from the housing of the upper cylinder a yoke-frame O hinged by rule-joints at its terminals with short extensions 0, from the sides of said housing so as to swing up into a vertical position and fold back over the housing. A Vertical guideway at the outermost point of the inner periphery of the said yoke-frame receives a duly fitted upward extension of the presser-bar A, which is held and adjusted by a hand-wheel screw 0*, set in the yoke-frame. The hinged joints of the frame are locked by set-screws, as required. By this construction the presser-bar partakes of the general vertical adjustment of its cutting-cylinder, but is independently adjustable to accommodate minor variations and may be swung back to allow removal of the lower cylinder.

I claim as my invention and desire'to secure by Letters Patent of the United States- 1.
