MATCHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 462,098, dated October 27, 1891.

Application filed September 22, 1888. Serial No. 286,141. (No model.)

T at whom, it may concern;

Be it known that I, CHARLES J. L. MEYER, of Fond du Lac, in the county of Fond du Lac and State of \Visconsin, have invented certain new and useful Improvements in Matching-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the 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 specification.

The main objects of my invention are to overcome the difficulties met with injointing and matching hard-wood lumber, particularly maple flooring, arising from the hardness of the material, toughness of fiber, knots, crossgrains, &c., to produce a better article at a smaller cost than has been possible with the machines heretofore used for the purpose, to effect a saving in material. dvc.

It consists, essentially, of certain peculiarities in the construction and arrangement of the mechanism employed to attain those objects, and hereinafter specifically described, and set forth in the claims.

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

In its general features and construction this machine is similar to a tongue-cutting machine designed to be used in connection with it, and the two machines may be combined, although I prefer to construct and operate them separately.

Referring to the drawings, A A is a strong heavy iron frame of suitable shape and construction to support and furnish bearings for the various essential parts of the machine herein described.

B is a horizontal bedway adj ustably attached to the front side of frame A by means of bolts 12 b, passing through vertical slots therein. as shown in Fig. 12. It is raised or lowered for grooving narrower or wider sections by means of vertical adj Listing-screws bl). (ShowninFig.1.) Alongitudinalgroove is formed in the bed B, as shown in Figs. 7 and 12, to receive the tongue, which is preferably formed on the sections by another machine before the grooves are cut in their opposite edges.

O C are milled or corrugated feed-rollers like those employed in the tongue-cutting machine presented in the application hereinbefore referred to. They are mounted 011 the upper ends of upright shafts cc and project through openings formed therefor in the horizontal bedway B. The shafts c c are supported at their upper ends adjacent to said rollers G O in boxes 0 c, which are swiveled in the bifurcated outer ends of slides 0 These slides (shown in detail in Figs. 16 and 17) pass horizontally through openings formed therefor in the front side of frame A and are supported in ways formed on brackets A, which are bolted to the inside of said frame. The brackets A are provided with ears a a, to which the shorterarrns of bell-cranklevers C are fulcrumed, as shown in Fig. 12, and with ears a a, between which are swiveled boxes 0 as shown in Fig. 17, for the upper ends of the upright counter'roller shafts 0. These shafts are connected with and driven by the shafts c c of the feed-rollers C C by pairs of like spur-gears c 0 (shown in Fig. 1,) and they carry on their upper ends counterrollers C O, placed opposite or adjacent to a numberof the feeding-rollers C in recesses in the front side of frame A. .Thelevers 0 as shown in Figs. 3 and 12, are connected at their angles with the rear ends of slides 0 and their rearwardly-extending horizontal limbs are provided with weights C adjustable thereon, so as to draw the feeding-rollers O 0 toward the counter-rollers O O or the front side of frame A, which constitutes, with the vertically-adjustable bed B, a guideway for the sections to be matched or grooved. The brackets A and the slides O are slotted to allow the passage of the shaftsc' through them and to permit of the movement of said slides.

C is a horizontal shaft supported lengthwise of the machine in suitable bearings and provided with bevel-pinions 0 a, which engage with and drive the bevel-gears c c on the lower ends of the shafts c c.

D D are spring-actuated presser-rollers journaled in vertically-movable slides D D, so as to bear on the upper edges of the sections as they pass through the machine and hold them down snugly on-the bed B. The slides D D have dovetailed guides, which work with similar ways provided therefor on the brackets D D which are attached to the top of frame A, and are formed at the upper ends with overhanging vertically-perforated ears for the reception of the adj usting-screws d d, as shown in Figs. 4 and 5.

d are internally-threaded sleeves formed at their upper ends with laterally-projecting flanges, between which and the slides D are interposed spiral springs cl, as shown in Fig. 4. By means of bolts d passing loosely through perforations in the tops of slides D and engaging with sleeves dithelatter are connected therewith, and the tension of springs d, surrounding said sleeves, is adjusted as desired. Byscrewsdd engagingthe upper ends of saidsleeves the slides D may be raised or lowered for grooving sections of different widths.

e e are spring'guiding and presser arms adj ustably secured by set-bolts in the vertical spindles E E, which are secured in like mannor in perforations formed for their receptionin bed B. The spring-arms serve to guide the sections to the feed-rollers O O and in connection with them to hold the sections snugly against the vertical side of frame A as they pass through the machine.

Taking the several cutters and their connections in the order they operate upon the work, and referring to Fig. 19 in connection with Fig. 1, F F are a pair of grain-cutting disks adj ustably mounted upon a short spindle f which is journaled in a spring-actuated slide D like those carrying the presser-rollers previously described. These disks are held at the proper distance apart by interposed washers f, more or less of which are inserted, according to the width of groove to be made, and they are adjusted and secured in place by nuts ff, bearing against their outer faces.

G is a roughing-saw mounted on a horizontal arbor g, which is supported in hearings on a slide G, movable transversely to the bed B in ways provided therefor on frame A. The slide G is movedin its ways, and the saw is adjusted tocut a groove in the properplace in the upper edge of a section of any particular thickness by means of a screw g engaging a nuton said slide and having a fixed bearing on frame A. The arborg is provided with a pulley G Referring to Figs. 13 and 14 in connection with Figs. 1 and 3, H represents the main cutter-head, composed of two disks or plates secured together by bolts k 72 and correend of a horizontal shaft 72, between washers 71 77. and is secured thereon by means of a nut 71 which assists also in binding its component sections or disks together. The shaft 7L3 is supported and has bearings in a slide H, movable transversely to the bed B in ways provided therefor on frame A, to which it is rigidly secured when properly adjusted by means of bolts passing through slots therein. The slide is moved and the cutter-head H adj usted transversely to the groove made by the roughing-saw G by means of the screw it, which has a fixed bearing in the frame A and engages with a nut projecting from said slide.

H represents a guard hinged to the frame A, so as to be brought over the cutter-head into position to arrest the chips and shavings made by the groove-cutters.

Referring to Figs. 9, 10, and 11 in connection with Figs. 1 and 3, K is the finishingcutter, which consists of a thick saw having its teeth beveled on the sides from base to point and formed to cut alternately on opposite sides of the groove, as shown in Figs. 10 and 11. To the cutting-edges of the teeth are given the exact inclination or bevel which it is desired to give to the sides of the finished groove.

The finishing-cutter K ismounte d on the The slide K is in turn carried bya slide K movable horizontally and parallel with the cutter-arbor in ways provided therefor on the frame of the machine. By means of the vertical adjusting-screw k, which moves the slide K vertically, and the horizontal adjusting-screw which moves the slide K horizontally, the finishing'cutter K may be very accurately adjusted to trim out the groove to the precise shape and width desired. A pulley K is mounted on the arbor of cutter K for connecting it with a driving-pulley. Instead of a finishing-cutter constructed as described, I may employ one having adjustable teeth, which maybe set out or in for wider or narrower grooves.

L is a tongued guide-block mounted on a vertically-movable slide Z, which is adj ustably attached by means of a bolt Z to a bracket L 011 frame A, as shown in Figs. 1, 3, and 8. It serves to hold the sections down to the bed and to guide them to the scrapers next to be described.

Referring to Figs. 1, 3, 6, and 7, N N are scrapers properly shaped to trim the sides of the groove to the proper shape and to clear the angles at the bottom of the groove of any projections or adhering chips or slivers left by the preceding cutters. These scrapers are each adjustably held by means of set-bolts in vertically-movable slides N N, which are in turn mounted upon slides N N movable horizontally and at right angles to bed B in suitable ways on brackets N N on frame A. The slides N and N are respectively operated and the scrapers very nicely adjusted to perform the work required of them by means of the adjusting-screws n 'n and n n.

Adjacent to the roughing-saw-main groove, cutting head, finishing-cutter, and scraper I place upright presser-rollers O O, which hold the sections at those points snugly against the vertical side of frame A, forming a part of the guideway, and between and adjacent to the several cutters are located at suitable intervals the spring-actuated presser-rollers D D, which bear on the upper edges of the sections and hold them snugly down to. the bed B.

Any suitable arrangement of driving mechanism may be employed to actuate the several cutters and the feeding devices of my improved machine. One convenient arrangement of mechanism for the purpose is partially shown in the drawings.

0 represents a counter-shaft supported in suitable bearings at the receiving end of the machine and provided with pulleys 0 0, connected, respectively, by belts with a pulley on a driving-shaft (not shown) and with the pulley G on the arbor of the roughing-saw. The pulley H on the shaft of the groove-cutter head H is connected by a belt with a con- Veniently-located pulley on the same or another drivingshaft.

M is a crossshaft supported at the delivery end of the machine and provided at its front end with a bevel-pinion m,w hich meshes with the bevel-gear c on the adjacent end of the roller-driving shaft 0 It is also provided with a pulley m, which is belted to a driving-pulley. (Not shown in the drawings.)

P is acounter-shaft supported in bearings on frame A above and parallel with the shaft M, and provided with a pulley p, which is belted to and driven by the pulley H on the shaft of the main cutter head H and with a pulley p, which is belted to the pulley K and drives the finishing-cutter K.

My improved machine operates asfollows: The bed B and the several cutters, scrapers, &c., having been adjusted, as hereinbefore explained, to cut a groove of the desired shape and size in the proper location in stuff of given dimensions, the sections are fed one after another to the first pair of upright rollers C O at the receiving end of the machine and by them forced into engagement with the others, which move said sections longitudinally on edge along the guideway in position to be operated upon by the several groovecutters. The outwardly-yielding Weighted feed-rollers C 0, bearing against the outer faces of the sections, hold them snugly against the counter-rollers O O and the vertical sidepf frame A, constituting a part of the guideway, and the vertically-yielding spring-actuated presser-rollers D D, bearing upon" the upper edges of the sections, hold the same snugly down to the bed B. The spring presser-arms eeserve to guide the sections to the upright feed-rollers and to hold them in place in the intervals between said rollers. They may be adjusted lengthwise in the spindles and the spindles raised or lowered and turned in the bed B, so as to cause them to hear at different angles at different points and with different press-- ures on the faces of the sections, as desired; As the sections pass under the grain-cutting disks F F two incisions are made in the upper edge of each section on each side of the groove to be formed, so as to prevent the splintering of the wood by the groove-cutters and insure smooth, sharp, and perfect edges to groove. The roughing-saw Gmakes a out bethereby relieving the groove-cutter H and allowing the material to be fed much faster through the machine than it would be possible without said roughing-saw. The cutters h h then form the groove approximately to the required shape, the cutterK trims the sides of the groove to the proper bevel, and the scrapers N N smooth the same and clear the angles at the base of the groove.
