lPLANE.

Ap lication filed January blade support is so formed that it can be readily attached to the body or frame of the plane and not only support the blade 1 but also form a convenient palm rest for the hand of the operator.

In the accompanying drawings:

Fig. 1 is a plan view.

Fig. 2 is a sectional view on the line22 of Fig. 1.

Fig. 3 is a front elevation with the blade in place.

Fig. f is a front elevation with the blade removed. 1

Referring to the drawings, the body stock of the tool is constructed of channel form in which 1 represents the bottom and 2 the sides, each of the sides being inclined downwardly and rearwardly toward the front and rear of the body as shown in Fig. 2. This body is constructed. of sheet metal bent to the shape shown.

The frog or support for the knife blade 3 is also formed of sheet metal and is shaped to form a forwardly inclined portion 4 and a rearwardly inclined portion 5. The forwardly extending portion at has at each side thereof a downturned flange 6, whichflanges are bent to lie parallel with the sides 2 and are secured, respectively, to the sides, prefer ably by spot welding. The rearwardly inclined portion 5 has at its rear end a lip or flange 7 which is bent so as to lie parallel with the bottom 1 and is secured thereto preferably by spot welding. The sides 5 of the rearwardly inclined portion 5 are bent downwardly. on a curve and the main part of this portion 5 lies above the upper edges of the sides 2 and provides a convenient rest for the palm of the hand of the operator. The forwardly projecting portion 1 is formed with an aperture 8, the metal being upset and threaded to receive a screw 9 having wings 10. The blade 8 is provided with a slotted opening 11 through which the screw extends so that the knife blade may be is, 1926. Serial No. 31,415. i

The bottom 1 is provided with the usual slotted opening 12 through which the edge of the blade extends.

Inassembling the parts the forwardend of the frog is attached to the sides 2 before it is bent, as indicated in dotted lines in Fig. 2, and a fixed rod is then placed beneath the frog at the point marked 13 in Fig. 2 and the rear portion 5 bent downwardly to proper position and secured as before stated by spot welding to the bottom 1. The central portion of thefrog or that portion indicated at 13 is preferably weakened by cutting away the sides thereof as indicated at 13 so that the frog may be readily bent over the stationary rod. 1

By'this arrangement it will be seen that a plane is provided which may be very simply and cheaply constructed so as to be sold at a low price. Further, by the arrangement of the blade support this support may not only be readily attached to the body of the tool but the rear portion thereof provides a convenient, place for the operator to rest thepalm of his hand in operating the tool.

3. In a plane, a body having sides, a onepiece member constructedas a separate part 160 from the body of sheet metal bent to a substantially inverted V-form to provide a forward downwardly I inclined blade support and a rear downwardlyinclined palm rest,

means for securing the forward part to the 1 0 sides of the body, and an integral part on the rear end of said palm rest bent tolie parallel with the bottom of the body and secured thereto.

clamped in different positions of adjustment. 4. In a plane, a channel-shaped body hav- 110 ing reara'ardly inclined sides, a one-piece support bent to a substantial inverted V- shape so as to extend for *ardly and rearwardly on an incline, integral lugs on the sides of the forwardly extending portion of said support and bent parallel with the sides of said bod and secured thereto and an integrally formed lug at the rear end of the rearwardly inclined portion of said support bent parallel, with the bottom of said body and secured thereto.

5. In a plane a ehannelshaped sheet metal body having rearwardly inclined sides, 11

sheet metal support having a forwardly extending portlon and a rearwardly extending portion, sald :lorwardly extending portion being secured to the sides of said body and said rearwardly extending portion being secured to the bottom of said body, said rearwardly inclined portion of said support being provided with rounded sides to adapt said support as a rest for the palm of the operator.

In testimony whereof, I have hereunto set my hand this 12 day of January, 1926.
