PLANING AND MATCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,564, dated November 1'7, 1885.

Application filed July ai,'1ss4. Serial Nd. 139,315. (No model.)

To all whom it may concern:

Be it known that I, EDWARD H. N. CLARK- soN, of Baltimore city, Maryland, have invented certain new and useful Improvements in Machines for Making Flooring, of which the following isa specification, reference being had to the accompanying drawings, forming part hereof, in which Figure 1 is a top plan View of front end of Fig. 2 is a similar view of the rear end of the machine, the rollers on the ex treme rear (as shown on left of Fig. 3) being omitted. Fig. 3 is a side elevation of the rear of the machine; and Fig. 4 is a vertical transverse section on line 00 00, Fig. 3.

Like figures indicate the same parts in all figures of drawings.

My invention relates to machinery for manufacturing flooring; and it consists in the construction, arrangement, and combination of parts, which will be fully described, and afterward specifically pointed. out in the claims, whereby a machine is furnished which will plane, rip, and tongue and groove three pieces of flooring out of a single board fed in at the front of the machine.

Referring to the drawings by figures; 1 is the bed of the forward part of the machine, upon which is mounted a roll, 2, a planer- 0 head, 3, driven by belts on suitable pulleys,

4, a pair of cutter-heads, 5 and 6, a second roller, 7, a pair of rip-saws, 8, driven by belts over pulley 9, and a pair of separators, 10.

The construction and operation of these devices will be well understood by persons skilled in the art, forming,as they do, a complete machine for planing the top of a plank, tonguing one side and grooving the other, and ripping the plank into three pieces. Attached at the 0 rear of this bed are two guideways, 11, each having a flange, 12, which guide-flanges recede outward from each other from front to rear of the machine, and are substantially continuations of the separators 10.

On the bed or the rear portion of the machine where these guideways end are mounted the following devices, viz: a frame, 13,

swinging on shaft 14 and carrying at its outer end a roller, 15, on one side of the machine, and a frame, 16, mounted on shaft 17, carrying roller 18 on the other side of the machine, the shafts 19 and 20, onwhich the rollers 15 and 18 are mounted, lying ata slight angle to each other, so as to be at the right angle to the guide-flanges 12; also, a shaft, 21, carryi'ng central roller, 22, at a right angle to the central line of the machine; also, a groovlng cutter-head, 23, and a tonguing cutter-head, 24, mounted on adjustable plates 25 and 26. The saws 8 are mounted on frame 27, which are also adjustable toward and from the center of the machine. The front end of the guideways 11 and 12 are adj ustably fixed to the bed 28, on which the saws and frames are mounted, so that they may be set with relation to the saw as desired, but are intended after being set to be adjusted simultaneously with the saw. The adjustment of the parts is made simultaneous by means of screws swiveled through the frame of the machine and engaging the movable parts, one of such screws being shown in Fig. 3, and two others, 30 and 31, being shown in Fig. 1. These screws are threaded into the movable portion, and are each provided with bevel-gear,which engages a similar bevel-gear on a longitudinal shaft, 32, as shown in Figs. 1, 3, and 4.

In Fig. 4 the manner of mounting these adjustable screws is shown, 33 being the bevelgear on screw 29, 34 the corresponding bevelgear on shaft 32, and 35 a block or bearing through which the screw swivels, the thread of which engages a nut attached securely to the frame which carries the cutting-head 24. The plank which it is desired to convert into three pieces of flooring is fed under the roller 2 and planer-head 3, which planes its upper edge. It now passes between the cutter-heads 5 and 6, the first of which grooves one edge, while the latter tongues the other. It passes onward under the roll 7, is ripped into three pieces by saws 8, (whose forward edges are slightly closer together than the rear edges,) which pieces are separated by separators 10, and furthers them apart by the beveled front edges of the guide-flanges 12. At about the time the rear end of the plank is leaving the roll 7 the front ends of the three pieces have at 38, 39, and 40. The left-hand edges of 38 and the right-hand edge of 40 are the outer edges, respectively, of the original plank, and are respectively tongued and grooved. The inner edge of the piece 38 is grooved by the action of the outside of the cutter-head 24. The inner edge of the piece 40 is tongued in a similar manner by the outer edge of the cutter-head 23. The central piece, 39, passes between cutter-heads 24. and 23, and is grooved and'tongued by them in the order named.. This completely finishes the three pieces of flooring, leaving them dressed, tongued, and grooved without the necessity of any handling after the original plank is put into the machine.

Having thus described my invention, what I claim is- 1. A machine for making flooring, embracing the following mechanisms, consecutively arranged in the order in which they are enumerated, viz: planing-knives, heads mounted on each side of the passage-way to tongue or groove the outer sides of a board, saws to rip the board longitudinally, separators located in line with the saws to enter the kerfs and laterally separate the pieces into which the board has'been ripped, and heads arranged and located at or beyondthe ends of the separators, whereby the inner edges of the separate pieces are tongued or grooved, parts being combined as and for the purpose set forth.

2. In a machine for making flooring, the combination of planing-knives located centrally in the path of a board, heads located at the sides of the board to tongue or groove its outer edges, and saws located in the path of the board to rip it longitudinally, as set forth.

3. In a machine for making flooring, the combination of planing-knives, heads located on the sides of the machine for tonguing or grooving the sides of the board, a saw located in the path of the board to rip it longitudinally, a separator located in the line of the saw-kerf to separate the pieces ripped apart by the saw, and a head located beyond andin line with the separator to tongue or groove the two inner sides of the separated pieces, as set forth.

4. In a machine for making flooring, the combination of heads located at the sides of the machine for tonguing or grooving the sides ofa board, saws located in the path of the board to rip it as it is propelled forward, separators in line with the saws to laterally part the ribbed pieces, heads located in line with the saws, and separators to tongue or groove at the sides of the machine for tonguing or grooving the sides of a board as it is fed forward, saws located in the path of the board to rip it longitudinally, and a separator located in line with and beyond each saw to enter the kerf and laterally part the ripped pieces, whereby their intermediate adjacent edges are brought into position to be operated upon, as set forth.

7. In a machine for making flooring, the combination, with mechanism for propelling the stock through the machine, of heads for tonguing or grooving the sides of aboard, saws for ripping the board into two or more pieces, and a separator for laterally parting thc ripped pieces, whereby their intermediate adjacent edges are brought into position to be simultaneously operated upon, as set forth.

8. In a machine for making flooring, the combination, with mechanism for propelling the board through the machine, of saws for ripping the board, separators for laterally parting the pieces, and heads for tonguing or grooving the edges of the ripped pieces, as set forth.

9. In combination, the saws 8, guide-flange 12, inclined and beveled, as described, the feed-rolls 15 and 18, set at a slight angle, and the feed-roll 22, set at right angles to the line of feed, as set forth.

10. In combination, the mechanism, the cutter-heads 5 and 6, saws 8, guides 12, cutter- heads 23 and 24, and suitable mechanism, substantially as described, whereby all the mechanism on one side of the machine may be adjusted toward and from that of the other side, as set forth.

11. In combination, the inclined guideflanges 12, the separators 10, and the saws 8, the forward edges of said saws being slightly nearer to each other, as and for the purpose set forth.

12. In combination, the series consisting of cutter-heads, saw, and guide-flange on one side of the machine, the similar series on the opposite side, the adjusting-screws 29, 30, and 31, and thelongitudinal shaft 32, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of subscribing witnesses.

EDWARD H. N. OLARKSON.
