SPECIFICATION forming partof Letters Patent No. 462,097, dated October 27, 1891.

Application filed September 5, 1888. Serial No. 284,619. (No model.)

To all whom it 77th/y concern.-

Be it known th at I, CHARLES J. L. MEYER, of Fond du Lac, in the county of Fond du Lac and State of \Viscoiisi1i, have invented certain new and useful Improvements in Matchinglowing is a full, clear, and exact description of the invention, which will enable others skilled inthe art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specilication.

The main object of my invention is to overcome the difficulties of jointing and matching hard wood, particularlymaple, for flooring, dec., arising from the hardness of the fiber, toughness of texture, knots and cross-grains, and to produce an accurate, smooth, finelyiinished joint with greater economy of material and at less cost than has been possible with the machines heretofore employed for the purpose.

My invention consists, essentially, of the peculiarities of construction and arrangement ofmechanism and parts composing my improved machine hereinafter specifically set forth, and pointed out in the clailns.

In the accompanying drawings like letters designate the same parts in the several Iigures.

Figure l is a perspective view of the front side of my improved machine. Fig. 2 is a similar view of the reverse side of the machine. Fig. is a vertical cross-section of a portion ot' the machine, showing in detail the edge feeding-roller and the gearing by which the lower roller is driven. Fig. e isa detail view of the gearing employed to drive the upper edge feeding-rollers. Figs. 5 and 5 are detail views, a front and side elevation ofV the jointer and its adjustable supportinghead, Fig. G showing a vertical section on the line c n, Fig. Fig. 7 isa vertical cross-section of the machine, showing the tonguingcutter, its carriage and connections, and one of the upright feeding-rollers and its connections. Fig. 8 is a horizontal section showing the upper bearings of a pair of upright feeding-rollers, a feeding-roller, and its counterroller. Figs. 0 and l0 represent, respectively,

each side of the tongue and thereby relievev the tongue-cutter.

The frame-Work of the machine consists of heavy iron shears A A, of suitable shape and construction to support and accommodate the Y various essential parts of mechanism to do the required work. To the front side of said frame is suitably attached a vertically-adjustable bed or way B, upon which the strips or sections are moved or guided on edge to and past the various cutters, Scrapers, the., and held accurately in position While operated upon thereby. Itis raised or lowered for the purpose of jointing and tonguing sections of different widths by means of the vertical adjusting screws b h. (Shown in Fig. l.)

C C are corrugated or milled feeding-rollers mounted upon the upper ends of vertical shafts c c and projecting upwardly through openings provided therefor in the bedway B. The roller-shafts c c are supported and bear at their lower ends in boxes attached to the frame A and at their upper ends in boxes swiveled in slides C2 C2, movable transversely thereto through openings provided therefor in the front side otl frame A, as shown in Figs. 1, 7, and S. To the inner ends of said slides C2 are pivoted the bell-crank levers C3,Which are fulcrumed to the inner side of frame A and project horizontally across the machine,

as shown in Fig. 7, being provided at their free ends with counter-weights CL. The downward movement of these levers is limited at the desired point by vertical stop-bolts c5, which are threaded in brackets attached to inner side of frame A on the side of the machine opposite the slides C2. The Weights C4 force the feed-rollers C C with a yielding pressure against the strip or section, causing them to engage its outer face and move it end- IOO Wise upon the bedway B to be operated upon by the cutters.

C' C' are upright counter-rollers, having either smooth or milled peripheries, which project slightly through openings in the front side of frame A, adjacent to the rollers C C or to some of them, as seen in Fig. 1. They -are mounted like rollers C C on the upper ends of vertical shafts c', which have bearings in boxes attached to the inner side of v the front shear of frame A. At their upper ends the shafts c pass through slots in slides C2, and their upper boxes are swiveled between ears on the ways in which said slides bear, as shown in Fig. 8. An independent lateral movement of the feed-rollers C toward and from the counter-rollers C' or the adjacent side of the machine is thus permitted.

C5 is a horizontal shaft supported lengthwise along the front of the machine near its base, as seen in Fig. 1, and provided with bevel-pinions c4 c4, which work with the bevelgears c2 c2 on the lower ends of shafts c c, and thereby drive the feed-rollers (l C. The shafts c c of the feed-rollers C and the shafts c' c' of the counter-rollers C are geared together in pairs by like gears c3 c3, whereby the counterrollers are rotated simultaneously with and at the samel rate of speed as the feed-rollers. E E are milled feed-rollers mounted'on the front ends of the transverse horizontal shafts e e in position to engage the upper edge of the strips or sections passed through themachine. The shafts e c bear at their frontpends next to said rollers E in vertically-movable bearings e', (shown in Figs. l, 2, and 3,) upon which the adjustably-counterweighted levers E E' bear. The rear ends of the shafts e e are provided with gears e2 c2, which are connected by a train of gears e3 e3, e4, and E2 with a pinion e5 on the shaft of a driving-pulley E3, as shown in Figs. 2 and 4. F is a lnilled feed-roller mounted on th front end of a short horizontal shaft f and projecting through an opening in the hedway B slightly above its upper face and directly below the rollers E, as shown in Fig. 3. It is driven in the proper direction to feed the strips or sections to the cutters and at the same rate of speed as the rollers E by means of a train of gears f',f2, and f3, which connect it with the pinion]4 on the shaft of a pulley F2. The roller F, the pulley F2, and the intermediate train of gears are all carried by a slide F', which is movable vertically with the bedway B, for the purpose of jointing different widths of stuff and independently of it for the purpose of elevating the periphery of said roller more or less above said bedway. lhe slide F is adjustably secured to the vertical portion of the bed B by bolts f5 passing through slots therein.

Referring to Figs. l, 5, and 6, G represents a rotary jointer mounted on a short horizontal shaft, which is supported and has bearings in a vertically-movable bifurcated slide G2 and is inserted in a recess formed therefor in the front side of the frame A and in the bed B. The slide G2 is adjustably secured to a bracket projecting from the frame of the machine by a bolt g, threaded therein and passing through a vertical slot in said slide. 1t is moved up or down, so as to bring the periphery of the jointer to the desired level with reference to bed B, by means of a vertical adjusting-screw g'. The jointershaft is provided between its bearings in slide G2 with a pulley G'. Directly above the jointer a spring-actuated presser-roller H is j ournaled in a vertically-movable slide H', which is in turn supported on a bracket H2, attached to the frame of the machine, as shown in Fig. 6. The slide H' is adjusted vertically by means of the screw h', (shown in Fig. 1,) and is borne down normally by the spiral spring h, so as to hold the strip snugly down to the bed B over the jointer with a yielding or elastic pressure. D is a cutterhead preferably composed of two disks similarly grooved on their inner faces to receive tongue-cutters CZ d, which are secured therein by set-bolts and are notched in theircuttingedges, as shown in Fig. 12, so as to give the proper shape to the tongue. The cutter-head D is mounted on the front end of a horizontal shaft supported at right angles to the bed B in bearings provided therefor on a slide A', which is movable lengthwise of said shaft in ways formed on frame A. The slide and with it the cutter-head are nicelyadj usted, so as to form the tongue in the proper position on the edge of the section by means of the horizontal adjusting-screw a. (Shown in Fig. 7.) The cutter-head shaft is also provided at or near the middle with a pulley D and at the rear end with a pulley D2. D3 is a guard having a hinge-connection with standards rising from frame A, as shown in Figs. 1, 2, and 7, for the purpose of arresting the chips or shavings made by the cutters d d. Adjacent to lOO the cutter-head D an upright weighted presser-roller holds the strip or section snugly against the vertical side of frame A, forming a part of the guideway. As the strip leaves the tongue-cutters in head D it passes under two horizontally-journaled spring-actuated grooved presser-rollers H, arranged, like that previously described, to bear on the upper edge of said strip or section and hold itsnugly down against the bedway B.

Referring to Figs. 13, 14, and 15, in connection with Fig. 1, I I are a pair of trimmingsaws located beyond the cutter-head D with reference to the movement of the work and mounted on the lower ends of upright arbors I 1 eachof which is provided wit-hapulley I2 and is supported in bearings on anadj ustable plate. These plates K are each pivoted bya bolt k to a horizontally-movable slide K' to which they are securely fixed, when adjusted, by lsetbolts lo k passing through curved slots in said plates, as seen in Fig. l5. The slides'K K' are in turn mounted upon vertically-movable slides K2 K2, and are adjusted horizon- Y Mr IIS Vframe of the machine.

tally thereon by screws k2 k2, which have bearings in ears 7a4 R4 projecting from the former and engage threaded holes in the lat-- ter. The vertically-movable slides are independently mounted upon the sides of an open vertical quadrangular bracket K4, formed on a horizontally-movable slide K3,whereby said saws are separately adjusted vertically and both adjusted together transversely to the bed B, so as to trim the tongue approximately formed by the cutters d d of head D exactly to the required shape, size, bevel, and location on the strip or section, the distance between the peripheries of the saws being adjusted by means of the slides K K and the inclination of their axes for varying the bevel of the sides of the tongue by means of the pivotedplates K K and set-bolts 7c 7o. 'The slides K2 K2 are adjusted vertically by means of screws 7c3 7a3, having bearings in ears 7a2 projecting from said slides and working with threaded holes in the bracket K4. The slide K3 is adjusted by means of a screw it, engaging a threaded hole therein and having a fixed bearing on frame A. The center pivot-bolts pass through the slides K and K2 and the bracket K4, which are each slotted to permit of the necessary independent horizontal and vertical adjustment of the saws I I, and next to the face of the bracket K4 said bolts have broad bearing-heads or washers and wrenchheads, whereby the foregoing parts are tightly held together when the desired adjustments have been made. On the opposite side of the saws I I from the presser-rollers I-I H, I provide another si milar counter-weighted presserroller I-l2, which co-operates with said rollers H I-I to hold the strips or sections snugly down to the bed B, adjacent to said saws. The slide h2, in which said roller is journaled, and the lever r* and weight h5, by which it is borne down upon the upper edges of the sections, are shown in Fig. 14. An upright presserroller C is located adjacent to the saws to hold the sections while being operated upon thereby snugly against the vertical face of the way in which they are moved and guided.

Referring to Figs. 9, 10, and 11, L is a scraping-tool properly shaped, as shown in Fig. 11, to finish the angle at the base and on one side of the tongue and to remove any projections left by the preceding cutters that would prevent the perfect closing of the matched joint when the jointed sections are put together. The scraper L isheld by a set-bolt in a socket formed for its reception in the verticallymovable slidcL, which is in turn supported in ways on a slide L2, movable horizontally and transversely to the way B in ways provided therefor on bracket L2, attached to the 'Ihe slides L and L2 are moved, respectively, by the adjusting screws Z and Z', and the scraper L is by this means very nicely set to do the work required by it. `Another spring-actuated horizontallyjournaled presser-roller H, like those previously described, and two upright weighted rollers (lv C are provided adjacent to said scraper at the delivery end of the machine to hold the sections firmly in place while being operated upon' by said scraper. .I J are spring presser-arms adjustably held by setbolts in the heads of spindles J J which are inserted and adjustably held in sockets in the bedway B, as seen in Fig. 1, for the purpose of guiding the sections to the feedingrollers C C, and of holding said sections in place between said rollers. J2 J2 are guideblocks secu red to the bedway B for the purpose of guiding the sections to the feed-rollers C C at the receiving end of the machine and adjacent to the cutter-head D.

Referring to Fig. 16, M M are a pair of thick concave roughing-saws mounted with their concave faces toward each other ou the arbor m', which is supported in suitable bearings (not shown) on the frame A of the machine between the presser-rollers E and thecutter-head D and parallel with their shafts. The saws are held at the proper distance apart to produce the requiredwidth of tongue byV means of the interposed washers m, more or less being used according as a wider or narrower tongue is desired. The saws M M are driven by a belt connecting the pulley on its arbor m with any suitable driving-pulley. (Not shown.) Although the machine operates successfully without these saws, their use materially increases its efficiency and capacity, besides relieving the cutter-head D and its cutters, and thus permitting it to do perfect work. IVith them the stuff can be fed through the machine much faster and the work is more perfectly done than without them. These saws are concaved to aiford the relief on their' sides which is ordinarily accomplished by setting, since it is difficult or impossible to set saws of the thickness of those which I employ.

Various forms and arrangements of driving mechanism may be employed to actuate the several cutters and feeding devices hereinbefore described. Among others, that shown in the drawings and hereinafter described conveniently serves the purpose.

tris a cross-shaft supported in suitable bearings in a supplemental frame A2, attached to one end of the main frame A. (Shown in Figs. 1 and 2.) Upon it are mounted the pnlley N, which is connected by a belt with some suitable source of power, and pulleys N', N2, and N3. The pulley 1 is connected by a belt with and drives the pulley D on the arbor of cutter-head D, said belt passing over the idler Q and under the tightener S, jonrnaled in a swinging frame. The pulley N2 is belted to and drives the pulley G on the jointer-shaft G.

o is a counter-shaft supported in frame A2 parallel with the shaft n. It is provided with a pulley O and with a pulley O', which is belted to and driven by the pulley N2, the belt passing under the tightener T.

r is a parallel cross-shaft at the opposite IOO ' the pulley O on shaft 0, with a pulley R',

which is belted to and drives the pulley E3, as shown in Fig. 2, and with a pulley R2, which is belted to and drives the pulley F2. (Shown in Fig. 3.) vided at the front of the machine with a bevelgear, (not shown',) which meshes with and drives the gear c6 on the adjacent end. of shaft C5. (Shown in Fig. l.) At the adjacent end of the machine, supported in brackets A3 A3, attached t'o the main frame A, is a counter- 4shaft p, parallel with the arbor of the cutter- 'The several adjustments of cutters, cutter-y heads, jointer, scraper, presser-rollers, &c.,

having been made, as hereinbefore described,

vto produce a tongue of the required shape and size on stuff of given dimensions, the sections are fed to the upright feeding-rollers C C at the receiving en d of the machine and are moved by them into engagement with the edge rollers E E and F, which co-operate with them to move each section along the bedway B in proper position to be operated upon by the jointer,roughingsaws, tongue-cutters, trimming-saws, and scraper. The lower edge of each section is first accurately planed true by the jointer G. roughng-saws, Vwhich cut away the greater part of the material to be removed on each side of the tongue, and the tongue-cutters then form the tongue, the trimming-saws accurately finishing the sides thereof as it passes between them, and the scraper clearing and perfecting the angle at the base of the tongue,

where a close joint is wanted when the stuff is put together, (the sections being correspondingly grooved on another machine presented in a separate application for Letters Patent, Serial No. 286,141, filed Sept. 22, 1888.)

The stuff to be matched should be first planed on both sides and sandpapered on theright side.
