BEVELING AND LINE-TRACING PLANER.

Specification of Letters Patent. at t ,21, 1917,

Application filed December 12, 1916. Serial No. 136,404.

To all whom it may concern.-

Be it knownthat I, GEORGE A. DICKIE, a

citizen of the United States, and resident of I the city of Seattle, county of King, and State of Washington, have invented certain new and useful Improvements in Beveling and Line-Tracing Planers, of which the following is a specification.

My invention relates to wood planers and particularly to planers designed for producing curved or beveled sides upon timbers. The type of planer to which it has been ap plied is that in which a reciprocating carriage is employed, the same being quite gene'rally employed for dressing large timbers.

The object of my invention is to provide a planer of the latter type with means whereby it may be used to beveltimbers and to vary the angle of the bevel at different points without stopping the operation of the planer.

My invention consists of the parts and combinations of parts which will be hereinafter described and then particularly pointed out in-the claims. 1

In the accompanying drawings I have illustrated my invention in the type of construction which is now preferred by me.

Figure 1 is a plan view of my beveling attachmentshowing a part of the planer carriage.

Fig. 2 is an elevation of the same parts, the carriage being in transverse cross section and a part of the frame of the attachment being broken away.

guides.

Fig. 3 is an elevation taken from across the carriage, parts of the carriage being shown in longitudinal section, but broken away directly in front of the beveling attachment.

Fig. 4 is an end elevation and Fig. 5 a plan view of the carriage showing the means employed for canting a timber upon the carriage.

Fig. ,6 is a section on a vertical plane through the head carrying frame.

Fig. 7 is a sectional plan taken just above the cutter head. i

Fig. 8 is a section showingthe circular Fig.9 is a section taken just above guide rollers .55.

In certain kinds of work, as for instance in the construction of wooden ships, it is necessary to bevel the sides and edgesof very many of the timbers used and such bevels rather often Vary in angularity throughout their length. To bevel a side or-edge of a timber where the angle of the bevel is constant is easily done by tilting the shaft of aside head, but where this angle is constantly varying, something more mustv be done;

By my invention I mount a side head so that it may be tilted within a considerable angle and providepmeans. for varying this angle whilev running- With this I also. employ a guide strip which is secured to the timber in a curve conforming with the curve which it is desired to give the side of the timber, and employ a guide, or guides, carried by the-head-carrying frame which enage the guide strip upon the timber to thereby determine the depth of out and thereby the bevel given the side.

The carriage 1, is of a size to hold the largest timber to be worked upon, it is herein shown as having its bed mainly composed of timbers l0 separated by spacing blocks 11 and bound together by bolts 18. I have also shown it as having an angle bar 12-at each side the path of travel of the carriage.

Where this device is installed as an attachment to a planer equipped to operate in the usualmanner, I prefer to mount the device so that it may be withdrawnwhen desired.

To this end I then employ a base 4 having guide ways 40 thereon which receive the feet 54: ofthe'main frame, so thatit may slide back and forth as needed. This'may be done by threaded shafts 43 which are journaled in brackets 12 of the frame 4: and thread through nuts 46 secured to or forming a part of the main frame 5. Gears 4A connect the two shafts 43 to insure like movements. One of these may be given a handle, as45.

The main frame has two upstanding arms,

51 forming a circularly curved. segment of considerable extent. As shown-these are rather more than half of a circle. These are separated "length-wise the carriage and have guide ways thereon 'supon which is mounted the cutter head carrying frame 6, which is shown separately in Fig. 6.

The guide ways, as shown, consists of undercut grooves in which fit the like shaped segmentlbars of :frame 6. The upper ends of these curved bars are connected by a bar 52, and may be otherwise connected.

The cutter head carrying frame 6 comprisesthe tWo'circular segment bars 60 which are connected together 1n suitable manner and provided with bearings :for the cutter head shaft. The upperand lowerends are 'conn'e'ctechby bars 6land"62, respectively,

these-having bearings '64, =66for the shaft.

I also prefer to provide a central arm or arms '63 which provide a central bearing 65.

The cutter head 'Zl should, for the work referredto, be of considerable axial extent.

I haveshown a standard type consisting ofa block 71,-mo'unted on shaft 7 and having knives 7 2 securedto its sides. A-driving pulley is secured on the opposite side of the central bearing.

The central end of the cutte1.' head,'or that end which is toward theaxis of the

circular segments

51, 60, being the lower as illus trated," should extend to or j u'st beyond the axis of thesesegments. The axis of the cutter head'and of' its shaft 7, should not be=a 'diam'eter,"'but should be ofl set enough 'to' bring the cutting sideiof the head to a diameter. The axis of the segments should also-coincide with the lower, outer'finished edge of the timber.

As a convenient means for shifting the cutter head carryingfr'ame to vary thebevel given the-side Of'tll timber, Ifhave provided the frame 6 "with a' toothed-circular segment'68'and have 'mounted an intermeshingiwo'rm 90"withina bar 52 whichiis con- .ne'ctediwith"the guideways 51. A shaft?) "hasa key -way 91, by- 'which a key associated 'with the workuvill permit free sliding of the worm on the shaft/"while binding them to turn t'ogethe'r. This feature is needed only if the' attachment is to be moved'bodily'back from the carriage.

In connection with the' "above mechanism I employ a guidewhich is placed upon the stick being beveled. This 1 preferably consists of a strip of woo'd SOof a length to extend throughout the length'of the' stick project slightly which is to be beveled. The stick or timber 8 fllZLS laid out upon its surface a line representing the distance to which it is to be cutback on this side. The guide strip is then secured with its outer face inward from this linea distance determined by the dimensions of the guide wheels or rollers carried by the cutter head carrying frame.

I have shown two types of these guide wheels, these beingeach adapted for its special conditions and capable of either being used, as may best fitthe conditions. @neof these consists of a guide wheel 7 5, which is side the cutter head. These shafts are,

threaded and-also the rollers 55. v The shafts 56 are provided, each with a key'way 57 and also rollers 55. The shafts 56 may each be provided With a hand wheel 58 by which it maybe held when adjusting the rollers 55. With a key in the key ways of shaftand roller, the two are bound together. This is secured by inserting a key 59. By removing the key, the roller may be run up or down.

The first thing to be done is to secure the guide strip '80 to the timber in conformity --with the amount it is desired to cut away.

The guide wheel, or rollers, as the case may be, are then adjusted to the height of the timber. enough to maintain the guide against the strip 80. This may be easily done by operating the wheel 92. In this manner a bevel of continuously varying angle'may be formed on the timber.

1 The 'roller directly upon the cutter head is theoretically- -m'ore accurate and correct than the rollers at each side ofthc head. For sharp variations in angle-of bevels,

The cutter head is then tilted which produce curves of relatively short "radius, this type 'of' guidewheel'is best.

Where, however, the curves are easier,"the rollers 55 are essentially aszgood.

For convenience in handling timber upon the carriage, I prefer to mount upon-the carriage a series of transversely extending bars or bunks 2, :for carrying the timbers, and to provide these with rollers 23 which above the beams 20 which form the bunks.

The beams 20 are preferably of :a metal section which has a top and'bottomflange, as a channel bar. These flanges arewprovided with a series of holes 21, those .in one beam being preferably staggered relatively to those in the other. I also prefer that those "in the lower-flange be slightly smaller than may beheld against dropping through when placed in the holes. These pins provide a backing for the timber.

If the bunks or transverse beams be pivoted, the face of the timber may be given ing the bunks. In such cases the use of the guide strip 8O and the guide rollers may be unnecessary. l r I WVhat I claim as my invention is;
