Specification of Letters Patent.

Patented Jan. 18, 1921.

Application led February 25, 1920. Serial No. 361,179.

To all whom it may concern.

Be it known that I, JOHN SzAKo, a citizen of the United States, residing at Kenosha, inthe county of Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to improvements in woodworking planes, of the type usually termed illister planes and has for its principal objecta to provide means whereby cross grainl planing may be effected, or the plane may be used for working with the grain, without altering the structure of the tool in its entirety.

Furthermore, in view of the fact that various gages and supports have been employed in tools of this character most of which are subject to inaccuracy, and do not give proper support to the plane when in operation, it is a further object of the present invention to provide an improved fence and depth gage in connection with a plane for adjusting the same and supporting. the same with reference to thework acted upon, and also in providing an improved handle for operating the plane whereby the pressure necessary to properly actuate the same is applied in the most effective direction with respect to the work.

. Forthe purpose of illustrating this invention, there is shown in the accompanying drawings one form thereof which is at present preferred, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and orl ganization of these instrumentalities as herein shown and described.

In 'the drawings: A Figure 1 is a side elevation of the plane. Fig. 2 is a top plan .view of the same. Fig. 3is a rear end view of the plane, and, Fig. 4 is a view ofthe cutter used with the same, and showing to advantage the lateral cutting edge which forms part of the subject matter of the present invention.

Like characters of reference refer to like or similar parts throughout the several Views' of the drawings, in which A designates the body or carri-age of the forwardly of the handle or grip member the usual frog or supporting block C for the cutting tool generally designated by D. The frog C has a lever cap screw l, a Y adjust ing lever 2, a supporting and adjusting nut 3, and a lateral adjusting lever Ll, all of which are conventional in construction and operate in the manner which is wel-l known in tools of this character. The cutter in the present instance (see Fig. 4) has an angular primary cutting edge 5 which is disposed diagonally to the Work and a lateral cutting edge 6 for use in trimming the side walls of a fillet in a manner which will hereinafter be described. The cuttery of course is supported on the frog C by a lever cap 7, and the handle is suitably secured in place by a handle bolt and nut (not shown). With the exception of the peculiar construction of the cutting edges of the cutting tool the above construction is conventional with planes of the character indicated.

Formed on the plane body or carriage A, and on the lateral edges thereof are side walls 8 and 9, and j ournaled in the side wall 9 which has suitable bearings 10 provided thereon are a pair of arms l1 which are capable of longitudinal adjustment and are retained in adjusted position through the medium of thumb screws 12. As clearly illustrated in Fig. 2 of the drawings the arms l1 are spaced apart and extend some distance outwardly from the side walls 9 of the plane. These arms have mounted thereon L-shaped bracket members 13, which are adjustable longitudinally of the arms ll through the medium of thumb screws 14, and .carry on their inner and free ends a fence vl5 which extends below andengages very lightly upon the planebottom as clearly illustrated in Fig. 3. The function of this fence is to limit the width of the slot when the plane is usedA in illister, and also to support the plane in position upon the work. By moving the L-shaped brackets longitudinally of the arms 11 the width of the cut may be regulated to a nicety and the'plane may also be supported by the fence when cross graining or planing with the grain of the work when such work is planed adjacent the edges thereof.

Also secured to the side walls 9 through the medium of nuts or screws 16 is a U- shaped handle 17 which'eXtends upwardly and laterally of the plane and provides a hand grip wherein the pressure upon the plane is directed directly against the work The side wall 8 of the plane carries longi-` f tudinallyspaced thumb screws 20 which extend through vertical slots 19 in upstanding Y portions 18 carried vby a de th gage 21 for limiting the depth of the llet cut by the plane.

As the cutter extends slightly below the bottom of theplane the fence 15 is provided with a recess 22 for permitting the same to pass thereover, and the depth gage 21 is provided with asimilar recess 28 so that the same will not contact with the lateral edge 6 of the cuttingtool D when the same is used in cutting-a filet. Furthermore the lever cap 7 is recessed as at 24 to permit shavings to pass from the lateral putting edge 6 of the cutting tool', and a partition 25 extends between the side walls of the plane in front of the cutter to reinforce and strengthen the yside walls.

As clearly illustrated in Figs. l and-2 of the drawings the side wall 8 is cutaway as at 26 for the reception of a spur 27 for use when the planelis used for cross graining; the operation of the spur is to sever the grain fibers so 'that the same will not strip laterally as the plane is passed thereover.

`In operationv the fence is adjusted to the proper Width of the fillet to be cut and the depth gage is adjusted for a like purpose whereupon the plane is supported with the left hand (or right hand as the case may be) by the handle 17 and moved forwardly in the usual manner. When the fillet has been cut the fence and depth gage respectively will contact with the work and limit an further action of the plane thereupon. lit, is pointed out that when the plane is used for cross graining or planing with the grain of a smooth surface that the fence may be used to contact with the edge of the surface and support the plane to facilitate the action thereof, and also that the depth gage may be let down even with the surface of the work to support the plane laterally and to give it more of a riding surface thereover. Furthermore b positioning the cutting tool diagonally of tfie work the action of the cutting tool thereupon is facilitated, and by forming a lateral cutting edge thereon the Walls-of the fillet will be surfaced as the fillet is being out.

From the foregoing description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction,

operation and advantages of the invention may be had, but while I have shown and described the device as embodying a specific structure I desire it to be understood that such changes may be made Ain said structure, as do not depart from the spirit and scope of the invention as claimed.

Vhat I claim is: f 1. A plane comprising a body having an adjustable fence and depth gage secured thereto, `a cutter carried in the body, the primary edge of the cutter extending diagonally of the cutter and of the work, one of the lateral edges of the cutter provided with a knife edge for surfacing a fillet, and a U-shaped handle extended upwardly and laterally relatively to the body for directing the pressure directly against the walls of a fillet.

2. A plane comprising a body having a cutter mounted therein provided with lateral and primary cutting edges, side walls on the body, adjustable brackets carried by one of the vside walls, a fence carried by the brackets for limiting the breadth of the cut effected by the plane, an adjustable depth gage mounted on the otherof the side walls vfor limiting the depth of a fillet, and a U- shaped handle extending upwardly and lat-y erally of the body for directing pressure in the direction indicated by the contacting faces of the fence and depth gage. 3. A plane comprising a body having `a cutter the primary edge of which extends diagonally of the cutter and of the work, 011e of the lateral edges of the cutter being provided with a knife-edge, and a handle extended upwardly a-nd laterally relatively to the body of the plane for directing the pressure ldirectly against the walls of the fillet.

In testimony whereof I affix my signature hereto.

JOHN SZAIO.
