To all whom it may concern:

Be it known that I, Gnonen A. DIGKIE, a citizen of the United States, and resident of the cityof Seattle, countyof King, and State of Washington, have invented certain new and useful 'Improvementsin Beveling and Line-Tracing Planers, of which the following is a specification.

My invention relates to planers which are provided with means for beveling the sides of timbers and also for cutting at different depths to thereby produce a curved or bent side edge. My invention particularly relates to the guide and depth controlling mechanisms employed with such planers.

The object of my invention is to produce a guide or depth controlling device for such planers which will be more perfect in its action than those previously used. To this end it consists of certain novel construcv tions which will be herein defined and the patentable features thereof defined by the claims.

In the accompanying drawings I have shown my invention in the form of construction which is now most preferred by me.

Figure 1 is a front face View of a cutter head having my present invention combined therewith.

Fig. 2 is an edge view of the same parts showing also the relation of the same to the work being operated upon.

Fig. 3 is a sectional plan, the plane of section being just without the frame bar.

F ig. 4 is a longitudinal section through the bearing at one endof one of the guide carrying shafts.

This invention is an improvement upon the machine shown and described in my Patent No. 1,237,487, for beveling and line tracing planer, issued August 21, 1917. This planer has a traveling bed upon which the work is placed and by which it is moved past the cutter head and the cutter head is mounted with its axis approximately vertical and is adjustable about an axis which is parallel with the direction of travel of the work. The present invention is an improvement upon the depth controlling means employed upon the machine shown 1n said patent, but the machine is otherwlse constructed like that shown in said patent.

The parts 67 67, are the same as the similarly numbered parts of said patent and 70 is a part of the driving wheel and 7 the shaft upon which the cutter head 71 is mounted.

Specification of LettersPatefnt. ywt m jog, 1 7, I Appficationfiied. June as, 1a17.- Sria1Na'177A59Q These parts are like .the' correspondingly;

numbered partsin said patent. With my present invention I employ a guide strip 80 which 18 securedto the upper surfaceof the "work" 8, as is described in said patent. I

also employ two shafts 56, one at each side of the cutter head. These shafts are also threaded and have guide rollers 55 which are screw threaded upon the shaft sothat they may be adjusted along the shaft to fit work upon timber of different depths. Shaft and rollers are both provided with keyways 57 and a readily removable key 59, whereby the rollers may be locked in any position to which they may be adjusted.

Instead of having the shafts 56 'journaled in the same frame as that in which the cutter head shaft is journaled, as was done in said patent, I journal them in two bars 5 which are pivotally supported concentric with the cutter head shaft.

In using the former type of construction, should it reach a point where the surface to be formed inclined much to the longitudinal extent of the timber as is indicated in Fig. 3, one of the rollers 55 would bear upon the guide strip 80 while the other would be held away therefrom and the surface formed by the cutter head would be outwardly of the true or desired surface half the amount by which the latter roller was held away from the guide strip.

To correct this inaccuracy is the chief obj ect of this invention. By mounting the roller carrying shafts in a frame or in bars which in turn are pivoted concentric with the cutter head, both rollers will always contact with the guide strip and the cutters will dress the timber accurately with relation to said guide strip. In Fig. 3 the dotted circle 70 indicates the path of the cutting edges of the cutters.

What I claim as my invention is:

1. In a beveling and line tracing planer, a depth controlling guide comprising two bars located at opposite ends of and pivoted concentric with the cutter head, shafts journaled in and connecting said bars, and guide rollers carried by said shafts and means for adjusting said rollers lengthwise of the shafts.

2. In a beveling and linetracing planer,

Ann r head, means for moving the work past the cutter head in a direction parallel With its axisof adjustment, anddepth' controlling in" combination, a cutter head, a frame in head,,means for'moving thework pastithe Co lies ol, this patent may; be obtained for which said cutter head" jOUIIlELlBdg. said:

frame being adjustable about an axis which isfperpendicular to the:- axis of: the; cutter cutter head in a direction parallel with its axis of adjustment and depth controlling guides comprising frame members pivoted concentric, with. and at opposite ends of the cutter head, a shaft journaled in said frame members at each side of the cutter headland guide rollers carried by said shaft.
