i 1 w 2,383,841 Y t WOOD PLANE l Bowman. Benn, Detroit, Mich. -nplicationgrebruary 12, 1943', serial No. 475,599'V z'olaims. (o1. 145-45) The present invention relates to improvements in wood planes and the like. .l

One of the objects of the present invention is to provide an improved wood plane.

Another o'bject is to provide a wood plane cumulated shavings.

Other objects and advantages residing in the combination, arrangement and construction of parts will morefully appear from a consideration of the following specification and the annexed claims.

In the drawing,

Fig. 1 is a plan view of the improved plane,

Fig. 2 is a side elevational view of Fig. 1, partly shown in vertical cross section, and

Fig. 3 is a side elevational view of the pivotal blade unit removed from the main body.

Referring to the drawing, the principles of the present invention aredisclosed in connection with a main plane body Il) having a rear portion I2', a front portion I4, and vertical side portions I6 and I8. Generally speaking, the improvements of the present invention in plane construction are subject to being embodied in planes of many shapes, sizes and types of constructions, and for this reason it is not my desire to limit myself to any specific type of plane or method of fabrication.

The structure for facilitating the removal of v accumulated shavings comprises a hinged unit generally designated by reference character 20, having a main portion 24 which functions as a continuation of the bottom portion 22 of the main body IIJ. The bottom portion 24 is illustrated as. having a thickened portion 26, having a hole 38 to receive the shaft 32, suitably supported at opposite ends in the sides I6 and I8. As more clearly shown in Fig. 1, the bottom portion 24 is supported in an opening 28 between the sides I6 and I8, and functions as the lower portion of a conventional plane which is usually an integral part of the plane body in lieu of being hinged as herein disclosed.

Threaded in the post 34 in the pivoted bottom portion 24 is a blade adjustment screw 36 having a knurled head 38. The opposite end of the screw 36 carries a T-shaped member 46 which rotates in a similarly shaped slot 42 in the cutting blade 44. It will be observed that the longitudinal axis of the adjustment screw 36 and lcutting blade 44 may be in oiiset parallel planes or in angularly disposed planes without aecting the operative relative between the T-shaped member 40 and the slot 42.

having provisions for facilitating the removal of ac tached handle is shown removed from the main The blade r44 is supported for sliding adjustment on the inclined portion 46being held by a chip breaking plate 43 through tightening the' knob portion 52, having a threaded shaft 54 oper'- atingin they threadedhole 56 inthe boss 51 of the pivoted bottom portion 24. The slot 58 'in the blade 44 permits adjustment of the blade with the members just described holding the blade firmly against the surface 46. In using the plane, one hand of the operator grips the knob handle 59 and the other the rear handle 66 which is supported in the hinged bottom portion 24.

The rear end 62 of the bottom portion 24 is beveled at 64 to rest on a similarly beveled portion 68 of the rear bottom portion 'I0 of the main bottom portion IIJ. With the beveled portions 64 and 68 engaging, the bottom portion 24 is in the plane of the front bottom portion 'I2 and the rear bottom portion 'I of the main body I0.

In dotted outline in Fig. 2 is illustrated the manner in which the pivoted bottom portion 24 of the plane is manipulated to facilitate the clearing of the shavings. For the reason that the operating pressure upon the pivoted bottom portion 24 is always in a direction urging the beveled portions 64 and 66 into firm engagement, my improved plane can be used without any latching mechanism for the pivoted bottom portion 24. However, to assure the proper positioning of the bottom portion 24 with the plane in use, any suitable releasable latch may be used between the [bottom portion 24 and the main body I0 of the plane. In the illustrated form, the handle has a bore 'I3 to receive the push rod 14. The cam I6 at the lower end of the rod 'I4 acts upon a pin 'I8 carried by the latch pin 80. A spring 82 urges the latch pin into engagement with a catch 82 and at the same time functions to hold the rod 'I4 in an elevated position. The lock pin 84 operating in the slot 86 holds the rod 'I4 and pin 86 in assembled relation. To pivot the bottom portion 24, the operator depresses the button 88 with his thumb at the top of the rod I4 to withdraw the pin 80 from the catch 82. Upon closing movement the inclined surface 94 will `cam the pin 80 into engagement with the catch 82,

In Fig. 3V the pivotal blade unit andthe at- Ibody I0 by loosening the shaft 32, which is preferably in the formV of a screw threaded into the side I8 and having a screw driver'slotted head countersunk in the side I6. This unit when removed from the main body I0 is capable of (being used as an additional tool for planing in close quarters and for removing material directly adjacent the shoulder. In this connection the knob 52 serves the same function as the knob 59 in the assembly shown in Fig. 2. It will also be readily appreciated that the unit shown in Fig. 3 may be used in plane bodies corresponding to the main body IU but of different lengths.

Having thus described my invention, what I desire to secure by Letters Patent and claim is:

l. A wood yplane comprising a main body portion having a Work engaging bottom portion lwith an opening defined therein, a second bottom portion located in said opening and pvotally supported intermediate its ends from said main body portion, a cutting blade supported on the forward end of said second bottom portion, saidl bottomv portions being spaced at the forward end ofsaid second bottom portion to dene an opening 'Y through which the cutting blade of the plane.-

projects to engage the work, abutment means supporting said bottom portions in the same plane by limiting pivotal movement of said second bottom portion in one direction, the forward end of said second bottom portion being` -swingable downwardly through said opening into avposition the plane of Said rst bottom portion, a cutting blade carried by the forward end of said structureand projecting through a forward portion of said opening', said structure being swingable in said 'opening to a position facilitating the l' clearing 'of-shavingsand the like from that portion of said opening through which the cutting iblade'projects and (1o-operating abutment shoulders on said structure land main body for limiting the swinging movement of said structure in one direction to dispose. said bottom portions' in the same plane. v
