BEVELING IPLANING-MACHINE.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed October 1, 1917. Serial No. 194,106.

To all whom t may concern: l

Be it known that I, JOSEPH A. SLOAN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Beveling Planing- Machines, of which the following is a speciication.

This invention relates to that class of machinery in which a side'head is employed for dressing a side face of a piece of wood to a gage line and to selected vertical bevels.

The object of my invention is the perfecting of machines of -this character whereby the work is positively guided in lateral directions during its progressive travel in the machine and while the planer head is being manually adjusted into vertical and inclined positions to afford a predetermined winding surface such as requisite in forming ship timbers. Y

The invention consists in the novel construction, arrangement and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings,-

Figure 1 is a front elevational view of a wood planing machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal vertical section taken substantially through 3-3 of Fig. 1. Fig. 4 is a detail sectional view illustrating the preferred mannerrof connecting the guide support to the machine frame. Fig. 5 is a fragmentary front elevational view of said support and a guide mounted thereon. Fig. 6 is a sectional view through 6-6 of Fig. 5, the guide roller being shown in elevation. Fig. 7 is a perspective view showing a timber to which a gage batten isl applied, mounted upon the machine rollers and the devices coperating with said batteri by which the work is guided in its` forward travel.

The machine frame comprises front and rear members, respectively formed of upright posts 10 and 101 connected from their upper and lower ends by beams 11 and 12. Rotatable between said beam members `is a circular frame 13 having a peripheral track element 14 engaging in grooved supporting rollers 15 and held in upright position by (means of annular face plates 16 provided on frame 13 and operating against wearing plates 17 provided upon the respective frame members.

Disposed diametrically of the frame 13 is the arbor 18 of a side cutter head 19 carrying knives 20. As shown in Figs. 1 and 3, the lower end of said arbor is journaled in the foot bearing 21 while its upper end extends through the journal box 22.

23 represents an electric motor whose armature shaft may be connected directly to the aforesaid arbor or through the medium of gearing.

Extending across the machine in front and to the rear of ythe machine frame are horizontally disposed shafts 24 and 241 upon which are mounted feed rollers 25 and 251, said feed rollers being arranged for 4axial movements by splines 26 provided on the re spective shafts. Said shafts are journaled adjacent to their ends in bearing boxes 27, said bearing boxes being movable vertically in guides 28 provided on the adjacent of said frame members.

For adjustably moving the feed roller shafts I provide upright screw threaded spindles 29 rotatable in bearings formed or provided in the guide 'bracket pieces 281 and engaging in threaded holes formed in the bearing boxes 27. The screw spindles 29 at each side of the machine are rotated by means of miter gears 30 from longitudinal shafts 31 through the agency of hand wheels 32. The shafts 31 are, however, connected to operate in unison by means of a sprocket chain 33 passing about sprocket wheels, such as 34, provided on the shaft, whereby the feed rollers may be raised or lowered from either side of the machine.

Circular frame 13 is rotatably moved for regulating the inclination of the cutter head 19 by means of a worm 35 taking in a rack 36 provided on the referred to frame. The worm 35 is mounted on an operating shaft 37 and rotated through the instrumentality of a hand wheel 38.

39 represents a bar extending transversely across the machine in substantially parallel relation to the plane of the feed rollers 25. The ends of the bar 39 extend into recesses 40 of guide brackets 41 rigidly secured to the frame members 10 and, as shown in Fig. 4, are yieldingly held upon the bottom 42 of the respective bracket recesses by means of thrust pins 43r which are each urged downwardly by a helical spring 44 interposed between vthe head 431 of the thrust pin and the bracket part 411.

Slidable upon bar 39 are blocks 45 and 46 respectively carrying below the bar 0pposing rollers 451 and 461 rotatable upon vertical axles 47. 48 represent set screws provided in said blocks for securing the same in adjustable positions through the bar 39.

The feed roller shafts 24 and 241 are operatively connected to rotate in unison by means of the endless chain 49 passing about sprocket wheels such as 50 mounted upon the respective shafts.

On the end of one of the feed roller shafts is a beveled toothed gear 51 engageable from diametrically opposite sides with either of the pinions 52 or 521, said pinions being rigidly connected to or integral with a sleeve 53 which is splined to a vertical shaft 54. This shaft is journaled in boxes 55 and driven by means of gearing 56 from a powerdriven counter shaft 57.

The operation of the invention may be explained as follows y The work as, for example, a curved piece of timber lV shown in Fig. 7, has secured thereto, as by means of nails or screws, a flexible strip T, hereinafter designated as a templet, disposed in parallelrelation with and at a definite distance from the cutting line L upon the upper surface. The work l is then placed upon the feed rollers 25 and 251 and the latter elevated by actuating the screw spindles 29, as before explained, until the top surface V1 of the work is brought up to Contact with the bottom ends of blocks 45 and 46, said bottom ends being disposed in a horizontal plane extending through the 1 axis of the rotary frame 13, vor nearly so,

said axis being represented in Fig. 1 by letter A. Said blocks are thereupon adjusted to have the peripheries of the respective rollers 451 and 461 engage the opposite sides of the templet T.

l The operator then manipulates the hand wheel 38 to edect, by means of worm 35 and rack 36, a rotary movement of the frame 13 for the purpose of regulating the inclination of the planerV head 19 to correspond with the bevel at which the adjacent. face of the work is to be cut. The motor 23 is then energized to rotate the head and the v hand wheel 38.

After the work has been properly surfaced on one side by passing through the machine in one direction,'it may be surfaced on its opposite side by returning upon the 4other side of the head. To meet such conditions, the blocks 45 and 46 should be shifted into dotted line positions indicated by a:

and ,1/ in F ig. 1, and the rotation of the feed rollers reversed by utilizing the pinion 52 or 521 which was previously unoccupied. Of course, but one side of the machine need be used, if-desired, but it will be readily understood that it is advantageous with heavy timbers to return the work from the back end through the machine rather than carrying it around and introducing it into the machine from the front end in a reverse position.

From the foregoing description, it will be noted that the work is positively moved in a lateral direction through the agency of a templet operating between two guide blocks rigid with the machine frame. Under such conditions, the feed rollers 25-251 are moved axially on the shafts.

By the provision of spring-pressed means for holding down the bar 39, to whichguide blocks 45 and 46 are secured, the latter are capable of yielding to accommodate them-` selves to any unevenness in the upper or lower surfaces of the work, or where the same are out of parallel with each other.
