WQOD-PLANING MACHINE.

SPECIFICATION forming part of Iletters Patent No. 240,724, dated April 26, 1881. Application filed September 28,1880. (Monet) To all whom it may concern Be it known that I, Jnrrn JnrPnsEN, of Provo City, in the county of Utah. and Territory of Utah, have invented a new and useful Improvement in Wood-Planing Machines, of which the following is a specification;

My improved machine is intended for dress: in g both sides of boards at once, for dressing the edges at any angle desired, for tonguing and. grooving, cutting moldings, and other varieties of work in wood.

I make use of two endless chains of links, fitted with cutters, combined with an adjustable bed, above and below which the chains are fitted to move in adjustable guides. I also use a feed-bed and feeding device, combined with circular saws, for carrying the material to the cutters and squaring the ends at the same time. The links of the chains are of pa. culiar construction, each being a plane having cutters adapted for doing the work required, according to the direction and manner of feed.

In the followin gdescription the construction and operation are described in detail with reference to the accompanying drawings, and the invention set forth in the claims.

In the draWings,'Figure 1 is a front elevation of the machine with the frame partially broken open... Fig. 2 is a sectionalplan view of the same on line or w of Fig. 1. Fig. 3 is a vertical transverse section on line gm of Fig. 1.

Fig. 4 is a face view of one of the planers.

Fig; 5 is an end view of the same. Fig. 6 is a side view of one planer with the cap removed. Fig. 7 is a view representing the planers in position for tonguing and grooving.

Similar letters of reference indicate corresponding parts. w I

The frame of the machine consists of end standards, A AA A, tied by longitudinal rails to at top and bottom. Between the two stand ards A, at the front of the machine, is fixed a horizontal feed-bed, B, that extends the full length of the machine. The two standards A A at each end of the machine are formed with vertical grooves in their adjacent faces to receive slide-blocks b. The'blocks :b at one end are connected with those at the other end by the guide-bares of the endless chains. There being an upper and lower chain, there are two blocks, 1), above bed B, and two below the bed at each end of the machine. The construction is similar in both the upper and lower sections, and the followin g description is of the lower section: There is a guide-bar, c, at each side of the chain. These are formed on their upper side with inwardly-projecting flanges c,'that sustain and guide the upper portion of the endless belt that is next to bed B, and at the lower portion of bars 0 there are fitted friction-rollers cl, upon which the lower portion of the chain runs, as shown most clearly in Fig. 3.

Upon the bars 0 at the ends of the machine are adjustable boxes for cross-shafts e, that carry gear-Wheels c, by which the chain is driven. The chain consists of the planes 0, jointed at their ends, described in detail hereinafter, which are formedwith teeth on theirinner surface for engagement- With the wheels 0. At the inner side of'standard A are hung levers ff, extending to and connected with an :arm, f, from a head or block, 9, that is fitted to slide in a'vertical groove formed in the front rail, 0.. The block g is fitted for movement by means of an adjusting-screw, g, secured in rail a and en gaging with nuts inthe block, as shown in Fig. 1. There are two levers,f, at each end of the machine, connected separately-by links it with the slides b, so that by the movement of block g the slides b, guide-bars c, and chain are simultaneously moved to or from the bed Gearing may be The devices for feeding the material forward upon the bed B are constructed and operated as follows: i

At the front of the machine, in bearings on i standards A, is fitted a shaft, 70, driven by bevelgearing from a counter-shaft, k, and carrying bevel-pinions ll, that give motion to two short verticalshafts, in. The shafts m are fitted in suitable bearing-blocks, m, at the ends of bed B, and carry the feeding devices, which extend over bed B from front to back. These feeding devices may consist of endless chains a, having spiked links and fitted on grooved pulleys o 0, the front pulleys being on the shafts m and those at the rear on studsfitted to arms that extend back from the blocks m; or, in place of the chains, there may be a series of spiked wheels, 19, (shown in Fig.2,) that are upon short vertical arbors and driven by a train of gearin g from shaft m. In connection with the feeding devices there are guides-p, for the material, fitted on bed B. The spikes of the feedin gchains or wheels project from slots in guides" p, and at one end of the machine the bearingblockm and guide 12 are fitted .adjustably on bed B, so that the space between them and the I guideatrthe opposite end of the machine can be varied as required. To permit suchadjustment;.thebevel-pi-nion lat that end is connected to shaft Joby a feather and; groove, so that it may slide, and an arm, I, from block m, extend-.Sinto a groove; in thehub of the pinion,

' whereby'itis moved with the shaft m and'kept tal arbors qfq! are sustained in suitable bear ingsi: On these arbors there are circular saws r, placed to cut in-linewith the guides p. The

a-rborsq are driven from shaft is by belts and:

pulleys, as shown in Figs. 1 and 3.

Uponlthe. guide-bars c, above bed 13, there are. hung levers s, which extend inward-and are-fitted at their inner ends with frictionrollers s, that will bear upon the material on bed A, v,to hold-the same in place. The outer ends. of levers s are held up with the-requisite forceby weights t, that are on the end of bandswhichpass overpulleys t to the ends of levers s.

The frames 6, forming. the links of the endlesschains, areshown separately in Figs. 4., 5,

and fi. Theseconsist of astock, '0, having side flanges, a), atzthe base, whiclr flanges are grooved to take upon the edges of the. flange.

c of guides c. The face 1 of the plane isfit ted. with; acutter for planing the surface of.

boards. The sideface, 2,is fitted with a cutter foniuse in; dressingthe edge of aboard, and,

inuconnection'with. a'cutter on the-face 3 for rabbeting. Theface 3 is one; shoulder of the plane, .whichshoulder can be provided with suitable cutters for tonguing. and grooving.

At the opposite; side. the plane is. provided.

with,=a;cap,w, held.ing place by. ascrew, so that it can be removed'to give access to the cutters. This cap is fitted with the-molding. cutter, and is shaped asrequired by the shape of the cutter." One cap'is to bereplaced by another, accordingto the shape of molding-dc.

sired. These planes are-connectedtogether at their end by hingeejoints, to formtheendless chain...

The operation of the machine is as follows:

To plane planks or boards the lower chain will be adjusted so that the cutters of the planes project above the surface of bed B through the opening, and the upper chain will be adjusted to or from bed B, according to the thickness of the boards. The planks or boards are then placed on the front of table B and pushed against the saws r, which square the ends, and the boards are then caught by the feeders n and carried between the planes. The rollers s catch the planed boards and prevent them from rising.

To tongue and groove, the planes will be brought together, as shown in Fig. 7, so that a board may be received edgewise between the shoulders 3. A suitable bed, 20, will be placed above bed B, on which the boards will be placed edgewise, (see Fig. 7,) and. a reciprocating feed-slide, r0 usedfor carrying the boards forward to the planes. The forward board drops in front of the slide-w 'and is carried in to the planes. The adjusting-screws work freely until the tongue and groove .are made, when the planes willbe separatedlto allow the finished board to drop out and another to be carried in.

In tonguing and grooving, the feed-slidew retains the board in position until the planes have completed their work. The feed-slide is moved by hand to push the boards in and ,draw them out, and suitable levers-are employed to relieve the-chains from the completed board.

In rabbeting and forming moldings the operation is the same, except that for-moldings the material is fed at the back of the machine.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1. In planing-machines, the combination of traveling. endless chains composed of .twoparallel endless chains of planes jointed together, a feed-bed, and'feeding-devices for carrying the. material between: the planes, substantially asshown and described.
