PLANE.

Application filed December 18, 1925. Serial No. 76,317.

rlhis invention relates to carpenters planes, and has as its aim to provide a plane with the improved means tor adjusting the cutter relative to the plane body, and which means is particularly characterized by its simplicity in construction, its economy 1n manufacture, and they 1effectiveness with which it performs its functions.

In accordance with the present invention,

the means for adjusting the cutter is mounted on the cap or lever which is clamped against the top ot the cutter so that the adjusting means is readily accessible, the parts may be easily assembled, and thecutter may be properly supported on the plane body at a relatively low angle, it desired.

@ther objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features oi construction, combination of elements and arrangementot parts which will be exemplified in the construction hereinafter set forth, and the sco-pe ot the application oit-.which willbe indicated in the apoended claim.

In the accompanying drawings, wherein I have shown, for illustrative purposes, one of the many embodiments which the present invention may take:

Figure 1 is a longitudinal sectional view through the plane;

Fig. 2 is a top plan view ot the cap on which the adjusting' means is mounted;

Fig. 3 is a top view of a slide adapted to be adjustably clamped to the cutter, and

Fig. -i is a view of the cutter or plane iron.7 f

It is, of course, understood that the body o the plane may be or any suitable or standard construction and shape. By way oi illustration, the plane body is shown in the drawings as having a sole 10, side flanges 11, an adjustable shoe 12 between which and the forward edge ot the sole is a slot or throat 13, and a frog o-r seat 14 adjacent the throat. The plane` body also has one or more pillars 15 which form a seat for the cutter rearwardly of the frog 14. At the forward end ot the plane. is the usual knob 16`and at the rear end a handle 17. rlhe cutter or plane bit, designated by the numeral 20,. has a central longitudinally-extending slot 21 adapted to accommodate an integral internally threaded boss 18 arising from the sole 10. The cutter is clamped in place on the seat provided by the frog 14 and the pillars 15 by a cap or lever 25 and a clamping or cap screw 26. The clamping lever has the usual key-slot 27, the larger portion of which is of suflicient diameter to permit the head of the screw 26 to pass therethrough and the edge of the smaller portion of which constitutes a seat for the inner tapered end ot the head of they screw.

In accordance with the present invention, there is provided on the cap an adjustable member with means for adjusting the same.

the adjustable member having cooperative engagement with the cutter so that, lwhen the member is adjusted, the cutter is moved rearwardly or orwardly, as the case may be, to change the extent` to which the cutting edge otl the cutter extends into the throat the adjustable member is in the form of a lever 30 extending through an opening 31 in the cap Yand pivoted in this opening on a transverse pin The upper end of the lever is in the form ot a yoke 33, and the yoke arms engage in a circumferential groove 34 of a nut 35 screwed onto a threaded stud 36 carried by, and extending upwardly from, the cap adjacent its rear end. The lower end of the lever is operatively connected with the cutter so that, when the lever 30 is'adjusted in one direction, the cutter is slightly withdrawn, and,

when moved in the other direction, the cutter is slightly advanced.. In the present illustrative showing, the forward end otthis lever extends through a rectangular slot. 37 in a slide 38 which is adjustably connected to the cutter. The slide 38 may be clamped in any desired position ot adjustment by means of a screw 39 which extends upwardly through a slot L1() in the cutter. The forward end of the slide has a depending lip L11 corresponding in length to the width ot', and adapted to engage in, the slot 21 so that the slide is held against rotary movement.

It will be seen that, to adjust the cutter, it is merely necessary to turn the nut in the right direction, and this may be easily done because the nut is in a position where it can be readily gripped. When the nut 35 is turned down on the stud 36, the cutter will be advanced so as to extend further through the slot and, when the nut is turned in such a direction that it moves In the present illustrative disclosure,

)un l upwardly7 the cutter will be withdrawn. The adjustable slide 38 is provided so that, as the cutter is shortened or worn away by Successive sharpening operationsg the proper relation between the lever 30 and the cutter may be maintained. In' one manner of speaking, the vtorward and rear edges of the slot 37 provide abutments on the cutter and between which abutments the lower end of the lever 30 is adapted to extend.

It is obvious that my improvements are verysimple in construction and arrangement and very effect-ive in operation.

As many changes could be made in the above, construction and many apparently widely ditlerent embodiments of this invention could be made without .departing from` tended to cover all of the Lgeneric and specific features ot the invention herein .described and all Statements of the Scope of the invention which, as a mattei' ot language, might be said to fall therebetween.

I claim as my invention:

A plane having a body, a cutter adjustably carried thereby and having a longitudinally extending slot, a cap removably clamped to Said body and againstvsaid cutter, Said cap having an opening adjacent its rear end, an adj uetable slide having an opening and a lip extending into and engaging the side edges et ISaidl slot, a screw Afor adjue-tably connecting said slide to said cutter, a lever pivoted in the opening of Said cap and having its lower endl ei )ging in the opening of said slide7 the upper end of Said lever having a i'orlr, a stud carried by said cap, and a nut on said stud having a circumferential groove in which the tori; of Said lever engages.
