WOODWORKINGNIACHINE.

SPECIFICATION forming part of Letters Patent No. 667,847, dated February 12, 1901.

Application filed May 3, 1898. Serial No. 679,630. (No modeLl To all 11171/0717, t may concern:

Be it known that l, HENRY W. MORGAN, of Roch ester, in the county of Monroe and State ot New York, have invented certain new and useful Improvements in Woodworking-Machines; and l do hereby declare the follow ing to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference characters marked thereon.

My present invention relates to woodworking-machines, and particularly to that class used for tonguing and grooving matched boards; and it has for its object to simplify and improve the construction of this class of devices, whereby they are particularly ad apted for operating on small boards or pieces, such as are used in the making of boxes, and whereby also the construction is simplified and but one cutter-shaft is required; and to these and other ends the invention consists in the improvements and combinations of parts, all as will be hereinafter fully described, the novel features being pointed out in the claims at the end of this specification.

In the drawings, Figure lis a perspective view of a matcher constructed in accordance with my invention; Fig. 2, an end elevation of the same; Fig. 3, a plan View; Fig. 4, a sectional View on the line o; a of Fig. 3; Fig. 5, a sectional view on the line b b of Fig. 4; Fig. 6, a sectional view on the line c c of Fig. 5; Fig. 7, a sectional view on the line cl d of Fig. 2; Fig. 8, a sectional view on the linee e of Fig. 2.

Similar reference characters in the different figures indicate similar parts.

In the present embodiment of my invention l have shown the machine as being double-that is to say, embodying two similar machines, one adapted for grooving one side of the boards and the other mechanism for cutting the tongue-and as the various mechanisms with the exception of the cutter, are the same, I have deemed it necessary to show the details ot' but one cutter and one set of feeding-rolls. The main frame embodies the side plates 1, having suitable supporting-legs and connected by cross-bars 2 and 3, the former being arranged nearer the center of the machine and having journal-boxes in which operates the cutter-arbor 4, having a driving-pulley 5 thereon. 'lhis arbor has at each end a rotary cutting-head 6, the one shown in Figs. 4and 5 being adapted for cutting the groove in a matched board A andthe Glitter at the opposite end embodying two similarcutters,separated,howcver,byaspace, so as to form the tongue on the lower edge of the board. The outer sides of the main plates 1 are provided with angular brackets 7, (shown particularly in Figs. 1, 2, and 8,) and through the lower portions of these brackets extend adjusting-screws 9, having lockingnuts thereon and carrying at their upper end the bed-plate or work-support 11, provided with a suitable aperture at the center for the passage of the cutter, said work-support also having brackets 12 attached thereto, with which cooperate securing-bolts 13, passing through slots in the bracket 7 and serving to hold the support when adjusted, as shown in Fig. 8.

14indicates the inner feed-rolls (three being employed in the present instance) keyed to the upper ends of the vertical shafts 15, supported in bearings formed in a frame 16, said frame being adjustable on anges 17 on the sides of the main frame by means of a suitable adjusting-screw 18 screwing into said frame 16 and passing loosely through a vertical extension 19 ofthe cross-bar 2, but prevented from longitudinal movement in the latter, as shown particularlyin Fig. 4. This frame 1G is rigidly secured in adjusted position by setscrews 20 passing through slots in the top of said frame and entering the flanges 17, and the adjusting-screw 18 is also secured rigidly by a set-screw 21. All the said screws just described are provided with hand-wheels, as shown, for convenience oi' operation. The lower ends of the vertical shafts 15 are provided With beveled gears 22, meshing with corresponding beveled gears 23, splined upon shafts 24 and longitudinally movable thereof. The shafts 24 are operated through suitable gearing from a pinion 25, secured to a beltpulley 26, (shown in Fig. 2,) and said belt-- pulley is driven by a belt 27 from a pulley 28 on a counter-shaft 29, on which the fast and loose pulleys 30 and 31 are mounted, a suitable belt-tightener 32 being employed, as shown.

33 indicates the outer or adjustable press- IOO ing and feedingmolls secured to the upper ends of shafts 34, mounted in separate adjustable frames 35, the lower ends of said shafts being provided with beveled pinions 36, meshing with pinions 37, splined upon the shafts 24 and adjustablezlongitudinally thereof 'wiith the frames 35, carrying the shafts. As a means for holding the gears 22, 23, 36, and 37 in mesh and to enable the gears 23 vandf 37'lto-f'be adjusted longitudinally of the shaft 24 When the rollframes or either of them is adjusted I provide the gears 22 and\36 with the `overhanging flanges 38, as shown particularly in.

tween the casting carrying the vertical shaftl and the gear movable on the horizon tal shaft.-

A separate frame 35 is provided for each of the outer adjustable rolls,.,said frames being provided Withthe rearwardly-extending portions 40, operatingin guides or Ways formed upon the frame 41, which latter is movable upon flanges or Ways 42 on the sides-of the main frame and adapted to be clamped rigidly thereon by gibs 43, held in position byy screws 44. This frame 41 is. bodily adjustable by means of an adj listing-screw 45, journaled loosely in the downwardly-extending 'armfon the/frame and entering a correspondingly-threaded aperture in the cross-piece 3 of the main frame and'provided with' an operating-handle 46. Each' of the roll-frames 35 -is provided with a rearwardly-extending guide-rod l47, passingthrough thedowvnwardl extension of the frame 41 and is pressed toward the coperating stationaryy roll by a spring 48,'encirclingsaid rod and engaging the frame 40 and also a pin or collar 490mv the rod. From thisiconstruction it will-be.

seen that the outer free rolls are permitted to yield independently and adjust themselves to the work operated upon, holding the latter` firmly between the rolls 14 and 33'and vfeeding it over the cutters.4 The whole series of! arranged on thev counter-shaft 29,-a suitableV belt-'tightener being employed embodying an arm 52, pivoted to the main frame at A53, carrying ,a tightener-pulley 54 and having a slot` 55, through which passes the clamping-bolt 56, as shown in Figs-2 and'5'.

Inv `the machine shown all the necessary adjustments may be accomplished quickly, the construction of the parts is simple, and but aA single cutter-arbor is employed for cutting both the male and female members of the matched boards. As the' cutter is arranged below the work-support and the axes of the feeding-,rollers are vertical, there is no necessityof changing the gage for boards of different widths.

The machine is particularly adapted for matching-the vedges of boards forming the covers-and Abottoms of boxes and is found to be admirably adapted for the purpose, al-

though with slight modifications it could beA usedfor other classes of work,such as m atched flooring.

I claim as my inventionl; In a woodworking-machine, the combination with .the main frame, and a Work-support vertically adjustable thereon, and a cutter-head, of a pair of vertically-extending feed-rolls mounted in bearings secured to the main frame, one roller being located on each side of the center of the cutter, a pair of opposing vertically-extending feed-rolls opposite the other feed-rolls, a frame adjustable Y on the main frame, separate frames carrying the last-mentioned feed-rollers, and means for movably supporting said'frames on the adjustable frame whereby` the movable rollers are held 'parallel to the stationary rollers, and springs interposed between the separate frames and adjustable frame allowing the former toyield independently of each other 7and of the adjustable frame, substantially as described.
