PLANING AND MATCHING MACHINE.

SPECIFICATION forming part .of Letters Patent No. 335,994, dated February 9,, 1886. Application fileil Novembcr i, 1855. Serial X0. 182,103. (No model.)

To all whom it may concern.-

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

My invention is in the nature of an improvement upon the class of planing and matching machines illustrated and described in Letters Patent No. 213,180,, granted to me, March 11, 1879, its object being to enlarge the capacity and enhance the efficiency of the class of duplex machines.

The improvement relates more particularly to devices for the more efficient treatment and finishing of two boards, whether of the same or different dimensions,at the same operation; and it consists, first, in the employment and constructive arrangement of two separate and independently adjustable planing-cylinders, second, in the employment and constructive arrangement of two separate independently adjustable and independently-yielding feeding-in and also feeding-out rolls; third, in the. combination, with the duplicated planing-cyl inders and the feeding-out rolls, of duplicate sets of feeding-in rolls; fourth, in the constructive arrangement of independent side feeding and guide rolls for startingin the lumber to the feed-rolls, and the combination of the same with the feedingin and feeding-out rolls and planing-cylinder; and, lastly, in certain other details hereinafter more fully described and claimed.

Some of the separate features of improve ment may be used independently, thereby realizing the advantage claimed in a proportionate degree; but the best results are to be obtained by a machine embodying all.

Mechanism embodying my invention isillustrated in the accompanying drawings,in which Figure 1 is a side elevation of a duplex planing and matching machine embodying my invention. Fig. 2 is a plan view of the same. Fig. 3 is an end view or elevation of the same. Fig. 4 is a transverse section and diagram showing the arrangement of the matcherhangers and planing-cylinders.

The same letters of reference are used in all the figures to designate identical parts.

The general construction of the machine, in respect to the arrangement of its feeding-rolls, planingcylinder, &c., in relation to the bed or platen, is similar toother machines of this class, and need not be detailed here.

The planing-cylinders A. A, for dressing the top surfaces of the boards, are arranged above the paths of the boards, and are j ournaled in bearing-blocks A A A A, having a sliding guide-connection with their supporting-standards B, upon which they are vertically adjustable to conform the cut to the desired thickness of the boards.v The supporting-standards B are secured upon the bedplate, and are vertically slotted to admit adj ustment-screws A? IOO AfA A swiveled through the bed-plate and engaging the bearing-blocks A, to effect the desired adjustment of the planingcylinders. The projecting ends of the screw-shafts A beneath the bed-plate are provided with bevel-pinions a, engaging with similar pinions, 6, upon shafts B B, journaled upon the bedframe, and gearing the screw-shafts A together in pairs, actuating-the rolls separately. Parallel to the shafts B B, and extending across their separating interval, is a third shaft, B similarly mounted, having upon one end a spur-gear, c, engaging a similar spurgear, 0, upon the shaft B, and having upon its-outer projecting end a spur-gear, d. A similar spur-gear, B is provided upon the projecting end of shaft B".

The shafts B and B project outward with squared ends,'suitable for the temporary application of a square socketed crank-handle, B, for turning the shafts. It will be seen that by the application of the crank-handle B either planing-cylinder may be adjusted independently of the other. Their simultaneous adjustment is accomplished by attaching to the handle B at its socket a spur-pinion, e, and attaching to the bed-frame a projecting stud in position to serve as a pivotal support for the crank-handle and its pinion, and, when the handle is applied thereto, to bring the pinion 6 into joint engagement with the pinions B and d. The action of the intervening pinion, e,,in such case operates the three shafts, B, B and B, simultaneously.

The carryingshafts of the planing-cylinders A project at opposite sides of the machinebed through and beyond their journal-bearings A, and each projecting end is provided with a belt-pulley, A for the application of an independent driving-belt to each cylinder.

Besides the advantages of an independent adjustment, already referred to, by which stuff of different thicknesses may be operated at the same operation, the torsional strains upon a long shaft are by this construction avoided.

The driving-belts are operated from the counter-shaft H, journaled at the end of the bed B, over suitable idler-pulleys, as shown in Figs. 1 and 2. The boards are fed to the planing-cylinders by two short independentlyyieldingfeed-rollers, D D, each operating in conjunction with a counter-roll, which may be either a single long roll E or two separate rolls E E, as preferred, arranged so that the upper surfaces of the same shall be approximately in the horizontal plane of the platensurface f.

I have shown in the drawings two constructions of the feeding-in-roll mechanism, either of which may be used, which I will proceed to describe separately. The first of these is shown in Figs. 1 to 3, inclusive, and is as follows: Each roll D is journaled in a pair of boxes, D D, mounted upon suitable guideprojections ofa stretcher-bar, D connecting the side posts or supporting-stands, D of the machine-bed. The boxes D D are provided with and mounted upon vertical adj ustingscrews D, the upper ends of which carry bevel-gears meshinginto corresponding bevelgears of a horizontal cross-shaft, a, mounted in fixed bearings between and across the stands D, and actuated by a hand-wheel. The revolution of the cross-shaft revolves the screws D, and raises or lowers the rolls D simultaneously. The screw-spindles D are adapted to slide to a limited extent through their bevelgears in order to allow the rolls to adjust themselves automatically and independently to boards of unequal thickness. \Veighted levers, pivoted to suitable projections of the cross-bar D ,may be arranged in the usual manner to bear upon the screw-spindles D*, and also on the inner end boxes of the rollers D, to equalize the pressure of the rolls upon the work by an adjustable leverage.

The construction and general arrangement of both sets of feeding-in rolls is similar. The advantage of a duplicate set of independently-adjustable feeding-in rolls will be more apparent when considered in connection with the action of the watcher-heads, and the devices to be described later; but it may be mentioned here that besides producing a more powerful and certain feed, conducing to rapidity and evenness of work, they carry the lumber through the machines always in a straight line. One set of rolls acting against the other prevents any slip or displacement of the lumber, thus requiring less skill and labor on the part of the operator, and consequently enhance the capacity and efficiency of the ma chine.

The more complete and preferred construction ofthe feeding-in rolls is exhibited in Figs. l t to 19, inclusive, and is as follows: The rolls D D are each journaled in boxes D D, having a vertical sliding connection with and upon the stands D D, and the screw-spindles D D pass through the boxes adjacent to thestands, terminating above in a hollow stretcher-bar, D", in which a bevel-gear, i, is placed on the end of each screw-shaft D, with a pin-andslot connection permitting the screw-shaft a limited vertical play therein. The horizontal shaft 9 is mounted longitudinally in the hollow stretcher-bar,with bevel-gears j j j j attached thereto, meshing with the gears i ii i of the screw-shafts, and at each outer projecting end of the shaft 9 is secured a hand-'wheel, F, for its rotation. When all the bevel-gears are in mesh, the mechanism operates, substantially as in the arrangement first described, to actuate all the sorew-spindles simultaneously. In order that one set or pair of the screw-shafts may be disconnected from the operation of the shaft 9, the bevel-gears jj are provided with grooved hubs, and have a pin-and-slot connection with the shaft 9, permitting a limited longitudinal play of the gears upon the shaft, or of the shaft in the gears, the journal-bearings of the shaft being arranged to permit a limited longitudinal play. Directly over and parallel with the shaft 9 a ICO second shaft or shifting bar, g, is journaled in or upon the stretcher-bar D, and carries yokes 7- is, each .with a rotating connection between fixed collars Z Z upon the shaft and engaging with the grooved hubs of the corresponding pinions, j, immediately below. A longitudinal movement of the shaft 9 thus by.

means of the shifting-yokes Z moves the pin ionsjj out of or into mesh with the corresponding pinions, z, governing the left'hand feed-roller D, Fig. 16. This movement is accomplished by fixed crank-handles or dogs on upon the shaft 9, which project outward through openings n of the hollow stretcherbar D. Two such handles are attached to the shaft-one near to and accessible from each side of the machine. The openingsn are provided with rack rccesses t t at the bottom, in which the handles engage to hold the shaft 9 in its ultimate longitudinal positions. A similar'crank-handle or dog, in, is secured at the projecting end of the shaft 9, engaging alternately in the grooves m m of a doublegrooved collar upon the shaft In the position indicated in Fig. 16, all the bevel-gears are in mesh and the rollers will be operated simultaneously. To disconnect the left-hand roll, 2-, one of the handles m is raised from one notch of its rack-recess, and by means of it the shaft 9 moved longitudinally to the left, carrying the gearsjj out of mesh wit-h the corresponding gears, i i, when the handles are dropped into the adjacent notches and held by gravity. By the partial rotation of the shaft 9 in lifting the handle m, the crank or dog m is also lifted out of one groove of the collar m and by the longitudinal shifting of the shaft y the dog m ismovedinto the adjacent groove m and thus the shafts g and g are secured in their proper relative positions. When the gears j j are thus out of mesh, the corresponding feed-roll D is disconnected from the adjusting mechanism. If, however, the parts being in the position shown in Fig. 16, it is desired to disconnect the right-hand roller, one of the arms at is'liftcd, (raising the dog m out of the groove 9222 and the shaft g is shoved to the right, disengaging the gears j j, leaving the gears j'j still in mesh, when the arms at are dropped again into their engagingnotches; also dropping the dog at into the groove on.

The same constructive devices are applied to each set of feedingin rolls, (whether two pairs or sets are employed or but one set,) and may also be applied to the feeding-out rolls.

Any approved construction of weighting mechanism may be employed in connection with the screw-shafts for securing the automatic adjustment desired.

As already indicated, the lower roll may be a single continuous roll extending across the bed of the machine beneath both feedingin rolls, or two independent rolls arranged in the same axial line with separate shafts and bearings. The same may be said of the lower feeding-out rolls. The latter or duplex contheir edges are dressed, tongued, and grooved The matcher-heads G G, op-

simultaneously. erating upon the inside edges of the boards, and G G, operating the outside edges of the boards, are attached to spindles G G G G, mounted on bracket-frames G, supportedand guided upon the horizontal cross-rails O O of the bed B, and are adjustable independently, bodily, in a horizontal plane by screw-shafts G having right and left sorew threads en-' gaging the bracketframes, respectively. The

screw-shafts project beyond the side of the bed-frame respectively, and by the application of a cranlchandle to their squared ends, respectively. the relative adjustment of the matcher-heads is effected. The matcher'heads G G are driven by a single belt, or preferably by two belts, as shown in Fig. 5, which, with the belts for driving the outer watcher-heads, G G, are given power from the common coun ter-shaft, H, at the end of the machine by suitable pulleys thereon.

The modification shown in Figs. 6 and T substitutes for the two inside matcher-heads a single central one, cutting the corresponding inner edges of the two boards.

As the boards pass beyond the matcherheads, they are caught between a pair of feed ing-out rolls, K K, which may be continuous or divided, the upper edge of which is journaled in vertically-sliding boxes adjustable by screws, actuated by bevel-gearing from a shaft journaled in an upper crossbar secured upon and between side stands rising from the frame in the same manner as the feeding-in rolls already described.

An under-cutter cylinder may be added to the machine at L to dress the lower side of the boards, if desired, driven by proper driving-belts from an auxiliary counter-shaft, H, and pulleys, and provided with suitable adj usting devices. The feed-rolls are driven by the usual train of gearing, as may be required.-

Figs. 11, 12, and 13 exhibit a. power-driven side roll for starting in the boards and retaining them against the guide-bar Q until they can be properly seized by the feed-rollers E and D. It consists of a roller, 0, upon a vertical spindle, 1 journaled in a bearingblock adjustable laterally in a cross-slot, recess, or depression of the bed-plate, and hav ing its driving mechanism arranged wholly beneath the bed-plate. The upper surface of the bearing-block is approximately flush with the surface of the bed B, and constitutes a platen, R, for the board to be acted upon by hub of the pinion 1? upon the shaft without ceasing to transmit the rotation of the shaft to the side roll, 0. The block (carrying the side roll) is adjustable laterally by a horizontal screw-shaft, P, swiveled in the bed'frame and actuated by a hand wheel or crank, P. The screw-shaft P is arranged to have a limited longitudinal play in its bearings against a spring, 8, or counter-weight, in order to allow the side roll, 0, to accommodate itself to varying widths of the board. Power is transmitted to the shaft 0 by a spurgear, 0 upon its outer projecting end from the train of gearing operating the rolls D D and 1*] through an intermediate gear, S.

In the duplex machine herein described there are two side rolls 0 and two corresponding sets of driving mechanism, operated by the same shaft 0 in the manner described; but a single guide-rail may be employed, presenting its outer lateral edges for grinding purposes.

Thus constructed the operation of the side roll, 0, is as follows: The board is placed flatwise upon the bed of the machine, with its end resting upon the platen It. The position of the roller being properly adjusted to the width of the board, t-heboard, being urged forward between the roller and the fixed guide rail Q, by the friction of the roller against its edge, will be carried forward in proper position by the roller until caught by the feedingin rolls D E, when it serves as a rear guide. until the board passes to and is received by the feeding-out rolls.

It will be understood that the driving mechanism of the side rolls is proportioned and adjusted to act upon the lateral edges of the board at the same relative speed as that of the feed-rolls proper upon the upper and lower sides. It should also be mentioned that a pressure-bar, which may be suitably provided with adjustable holding-surfaces to act upon the boards, is arranged across the machinebed above the lower surfacing-cylinder, L It has been omitted in the drawings, for convenience of illustration of the other parts described.

Having described myinvention, I claim and desire to secure by Letters Patent of the United States l.
