PLANE.

APPLICATION FILED MAY 6,' 1902.

930,307, Patented Aug. 3, 1909.

The upright portion or back of the yoke eX- tends upward and is secured at the downwardly bent portion 36 to the frog at a point just above the opening 20 in the face of the frog. rlhrough this opening access may be had readily to the securing screws 31 in the base. Y

When the plane iron and plate are adjusted in position and secured to the frog by means of the cap iron 6 and cap screw 61, the frog is subjected to stresses of considerable amounts. To provide for meeting these stresses it is desirable that the sides ofthe frog should be bent down and depressed to form reinforcing iianges. It will be noted that these flanges as shown are substantially triangular in form and correspond in depth from the face of the frog very closely to the diagram of changes in bending moments which would occur in a beam loaded in the center and supported at the ends, which is the case that we have herein. The cap iron 6 is provided with a cam lever for effecting the requisite pressure between the cap and the plane iron or the plane iron plate for holding the parts in place.

The upper end of the-bearing face of the frog is depressed in a truss-like form at 29 to rovide a recess in which the lower end of the aterally adjusting lever 9 may be pivoted at 92 and operate. The end of this lever 9 may be provided as is usual in planes of this character with a disk 94 which cooperates with a slot 40 in the plane iron 4 to effect the desired lateral adjustment. r1`he depth of the cutting edge of the instrument may be adjusted by means of what is known as a Y-adjustment 7 in which the nose 7 5 projects forward through an opening in the face of the frog into a hole 50 in the plate which is above the plane iron. e

The plane-iron and plate being secured together by the screw 45, movement up and down of the if-adjustment will also operate the plane iron itself. j

The face ofthe frog is provided with a perforation or recess to receive the head of the securing screw which is thus let into the platform and allows the plane iron to have a smooth and even bearing upon the face of the frog. Above this recess the metal of the frog may be out out and bent back in the form of ears 27 which will provide bearings for the pivot ofthe Y-adjustment. 1n order that these ears may he bent back at convenient angles and with as little injury to the metal as possible, it is desirable that the sides of the recess should be cut back both above and below the ears and at the base thereof as shown particularly in Fig. 3. 1n order that the Y adjustment 7 may have a secure and even bearing and also to increase the economy and efficiency of the device, we have made the Y-adjusting lever 7 of sheet metal as shown in Fig. 5, in which 7 G, 70 are perforations in the two opposite sides of the thus be seen that the lever has two bearings and that they are spaced apart a considerable distance. The lower ends or" the arms 7S coact with the adjusting nut S which opcrates on the screw S1. ln this construction as shown particularly in Fig. 6 the adjusting screw S1 is conveniently seated in the back of the yoke at a point near the top thereof where the strength and rigidity of' the same would be suflicient to give it asecure bearing. 1t is also desirable that the face of theirog should have a reinforcing piece at the point where the cap screw 61 is attached thereto.

in holding the yoke and the frog more securely together. The upper portion 33 of' the. back of the yoke may be cut away as appears most clearly in Fig. 3, and thus provide an easy and convenient access for the purpose if desired of riveting the plate 36 to the frog 2. The lower front end of the yoke acts also as a reinforcement to the lower iront edge or toe of the i'rog in the structure herein shown, and materially adds to the strength and eiiiciency 9i the parts since the pressure of the lower end of the cap iron 6 is applied near this point. The cutting edge of the plane iron may be projected through' the throat or slot l0 in the base of the stock portion just in front of the toe of the frog. The face of the frog is also reinforced as shown by the depressed portion 29 which in stamping the article forms a corrugation at that point substantially opposite the point of application o1 the pressure applied by the cam lever 65 at the upper end of the cap iron. The whole structure is exceedingly light in weight and although very simple and economical in its construction is durable and erlicient.
