' Application iiled February 25 1902. Serial No. 95,577. (No model.)
To all whom t may concern:
`ject of the Kingof Great Britain and Ireland,
residing at Silsden, in the county of York, England, have invented certain new and useful Improvements in Machines for Grooving Lumber, of which the following is a specilicatio'n. i
My invention relates to machinery for woodworking; and it consists of a machine for grooving lumber on both lsides, one set of grooves ou one side intersecting the set of grooves on the other side, so that the lumber is produced as an open-work. This material I design for use as lattice-work, gratings, and iioors, where the free escape of water may be desired and for other uses.
In describing my invention in detail reference is made to the accompanying sheets of drawings, in which- Figure 1 represents a side elevation of a machine for cutting grooves on both sides of lumber. Fig. 2 is an elevation showing the opposite side of the machine. Fig. 3 is a plan. The remaining illustrations are detached details, Fig. 4 representing a section through the machine, showing the connections between tappet-shaft and means adoptedffor vertically operating the portion of table supporting the lumber during the transverse cuts. Fig. 5 is a sectional elevation through that portion of the machine for giving transverse movement to the circular saws for cutting the transverse grooves. Fig. 6 is a sectional plan showing the bevelwheels and shafts for eecting the transverse cutting; and Fig. 7 is a diagrammatical view drawn to a larger scale, showing the shaft in section, to which the cutters are attached for cutting the grooves on the under side of the lumber and the circular sawsfor cutting the transverse grooves on the upper surface.
The operative parts of the machine are supported by suitable framework A, and motion is imparted to the machine jby a pulley B, mounted on main shaft B of the machine, the said shaft being also provided with a loose pulley B2. v
The lumber C is fed to the rotating rollers C C', driven from shaft D through the bevelgears D D', operating-shaft D2, upon which is secured a spur-pinion D3, gearing into spur- Iwheel D4 on shaft D5, upon which is a pinion D6, gearing into wheel D7 on shaft D8, to which is also secured a wheel D9, gearing with wheel D10 through intermediate pinion D11,the shaftsupporting wheel D10 transmitting motion to the feed-rollers C byspur-pinions applied in the usual well-known manner. The bottom pressure or feed rollers are carried by the standards F, and the top pressure-rollers C are mounted in frames E, hinged on a pin E, passing through said frames and through the standards F. The outer ends of frames E are connected by rods E2 to a weighted platform E3, by which pressure is given to the rollers C for gripping the lumber C in a manner for propelling it in the direction of arrow toward the cutting devices. The top pressure-rollers C can be raised to admit of the lumber being placed between the feed-rollers by operating the lever Fwhich is connected to lever F2, secured on shaft FS, suitably carried,
and upon the shaft is secured an arm F4, from which is suspended weighted platform E3, connected by rods E2 to the frames E, carrying top feed-rollers C'.
Upon standards G is mounted a shaft G', driven by pulley G2 from pulley Gr3 on main shaft B. The shaft G is square at G4 for a portion of its length. In the square portion undercut grooves G5 are made for the reception of the heads of bolts G6, employed for securing the cutters H, utilized for cutting the longitudinal grooves C2 on under side-of lumber O, the depth of grooves being regulated by the adjustment of the distancel the cutting edge of said cutters projects beyond the square shaft, each cutter being provided with a slot for the reception of a bolt G6 for securing the cutter H and adjustment of same for regulating depth of-cut. A roller J, supported by a frame connected to shaft J', is placed immediately above the revolving cutters H, carried by shaft G. The rollerJ rests upon the upper surface of the lumber, and pressure is applied to the roller J and lumber by a lever J 2 and weight J 3. The lumber C, vpassing over the revolving cutters H, is grooved on the vunder side at C2 and, continuing its course, passes over the hinged support K, provided with a pressure-roller KX, andl to the hinged support K is jointed a table K', the
opposite end of said table being jointed to an IOO extension K2, hinged to bracket K5. The portion K' of table is secured to the sliding bars L L, reciprocated vertically, for the purpose and in the manner as hereinafter described. The transverse grooves C3 on the upper face of the lumber C are cut to a depth so as to intersect the longitudinal grooves C2, thus producing lattice-work suitable for gratings and oors, where the free escape of water may be desired, and for other uses.
- Upon the rotating shaft M is mounted a cam-plate M', in the cam-groove of which engages au antifriction-bowl attached to a lever M2, supported by shaft M3, mounted in suitable bearings. The upper portion of lever M2 is coupled to the carriageN byliuk N' for giving a sliding motion in accordance with the cam-groove to the said carriage and parts connected or mounted thereon. Rotary motion to the cam-shaft M is transmitted by the diagonal shaft O through bevel-gears O' and spur-gears O2.
Upon the reciprocating carriage N, guided by ways, is bolted a plate N2, also prepared with guiding-ways for the reception of a frame N5, placed thereon, supporting the journals Nl and circular saws N5, driven by the pulleys N5. The frame N5 and circular saws N5 are reciprocated transversely across the lumber C for cutting the transverse grooves C5 ou top side to a depth intersecting the grooves C2 cut on the under side of lumber. The frame N3, along with the circular saws N5, supported on frame N3, is reciprocated longitudinally by the rotating cam-plate M', operating as before described, and is also reciprocated transversely. This transverse motion is effected in the following manner: The rotating shaft D is driven from the main shaft B' by a belt and pulleys, and upon the shaft D is secured a pinion P, gearing into spur-wheel P' on shaft P2, on the opposite end of which is a wheel P3, gearing by an intermediate wheel with wheel P4, motilited on shaft P5. Attached to wheel P4 is a small pinion P5, (shown dotted,) gearing with spur-wheel P5, which transmits motion to short shaft P5 through the train of spurwheels shown in Fig. 2. The short shaft P5 is supported in a suitable manner, and upon the opposite end of the shaft a miter-wheel Q is secured, gearing with a miter-wheel Q', secured on shaft Q2, grooved at Q5 for a portion of its length forlhe reception of a featherkey fixed in bevel-wheel R, the boss of which is of such length as to extend through and be supported by bracket R', secured to the reciprocating carriage N or plate N2, bolted thereto. The bevel-wheel R gears into one, R2, of larger diameter, supported by bracket R3, also attached to the reci procating carriage N or plate N2 bolted thereto, so that these two wheels are always in gear, although the shaft Q2 is adapted to slide through bevelwheel R. Projecting from the face of wheel R2 at some distance from the center of same is a pin R4 of a length to engage with a slot R5, formed in bracket R5, bolted to the frame N3, which by my combination has a longitudinal and transverse motion. The longitudinal motion is imparted by the camplate M and the transverse motion by the pin R4, rotating and sliding in the slot R5 of bracket R5, thereby causing the said bracket, frame N3, and circular saws N5 to reciprocate transversely, the circular saws N5 cutting transverse grooves C3 each time they pass through the lumber C, traveling longitudinally over the table K'.
In order to keep the lumber C in position for cutting, it isl held against a fence K4 on table K' by one or more springs S, each supported by a bracket S', attached to the table K'. Each end of spring S is provided with a small antifriction-pulley S2, held in contact with the edge of lumber by the said spring. The downward pressure on the lumber C is obtained by bars T, placed on each side of the circular saws N5. These bars T are connected to blocks T', provided with vertical spindles T2, guided by sockets T5, secured to the frames supporting circular saws N5. Each spindle T2 is provided with a collar T4, and between the collar and cap T5 at top of socket T3 is a compressed spiral spring T5, further compressed and operated in the following manner:
The lumber C is continuously fed between the rollers C C', is grooved on the under side when passing over the revolving cutters H, and when the circular saws N5 are traveling across and cutting the transverse grooves C2 on the upper surface the table K is elevated for bringing the lumber to a position for transverse cutting. The rising and falling of the said table is effected by the tappet U, which on rotating depresses the plate U'. To this plate is connected a transverse lever U2, hinged at the opposite end to the machineframework, and at or near the center of the said lever bars U3 are connected, arranged to couple lever U2 to levers U4 U4, fulcrumed at U5. The opposite ends of levers U4 are connected to the sliding bars L L, each secured to the under side of the table K' and mounted so as to freely slide in the guideplates L' L', attached to the machine-framework. It will be readily understood that on the full parts of the rotating tappet U depressing the tappet-plate U' the sliding bars L L will be moved vertically, thereby operating the table K' and bringing the lumber Cinto position for being cut on the transverse movement of the circular saws N5 in either direction, at the same time further compressingthe spiral springs T5 suliicient for holding the lumber C firm during the transverse cutting. As soon as the circular saws N5 have passed across the traveling lumber C the table K' is allowed to descend, where it remains until the lumber C has traveled forward the required distance ready for the return of the circular saws N5, when the table K' is again elevated and another series IOO IIC
of transverse grooves C3 cut.l The lowering of the table VK' is effected by the gravity of the said table, assisted by a spiral spring W, attached to the tappet-plate U and end of lever' W', suspended by a'link W2.
The rod X is connected to one arm of a bell-crank lever X. The other arm of said 'lever is connected to a projection from lever Y of the rst order, the opposite end of the leverY engaging with a groove in boss of Yplan-e and through the material at the intersection of the grooves, and substantially as described.
2. Inka machine `for grooving lumber,vvcu t ters for makinglongitudinal grooves on one side of the material, cutters formaking grooves transversely on the other side of the feeding means material, said cutters being arrangedto out into the same intermediate plane and throughl the material at the intersection of the grooves,
means for -feeding and continuously propelling thelumber, and means for firmly holdingor securing the traveling lumber during the longitudinal and transverse cuttings.
In testimony whereof I affix my signature in the presence of two witnesses.
