PLANE.

Application led October 2, 1902, Serial No. 125,686.

To all whom 'it may concern: i Be it lnown that I, HARVEY M. l/VOOD, a citizen of the United States, a resident of Los Angeles, in the county of Los Angeles California, formerly residing at Denver', in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Planes, of which the following is a speciiication.

My invention relates particularly to a device for clamping and supporting the planeiron in position.

It also embraces means for plane-iron.

One object of my invention is to provide simple and effective means whereby the plane-iron or bit may be readily inserted in I the throat or removed therefrom, the means I for operating the mechanism for accomplishing this purpose being located behind the frog, and controlled by the handle of the plane.

Another object is to provide a construc- I tion whereby the plane-iron may be removed j adjusting the from the plane for sharpening or other purposes without requiring any other parts of the plane to be detached or removed from the plane. j Another object is to provide a means for y supporting the plane-iron in such a manner that chattering' of the plane-iron will be prei vented. Another object is to provide a construcl tion in which the plane-iron lies flat against ,l the cap and also flat against the frog; there f being no free space between either the planeiron and cap, or the plane-iron and frog.

Another object is to provide a plane in which the plane iron lies v['lat as above stated and the bit is conveniently and positively adjustable.

In carrying out this invention, l provide the plane with a cap having two pivots carried by the cap and extending at right angles to each other above the bit, and provide levers on the-pivots respectively engaging to operate the bit for adjusting the same laterally and longitudinally. The plane is thus I provided with adjusting levers wholly above the bit and most readily accessible, and moving transversely of each other to move the bit laterally and longitudinally so that the operator has the adjustment of the bit most fully underhis inspection and control while adjusting the'same, and can accurately adjust the bit in both directions with greater Specification o' Letters Patent.

facility than heretofore, and I am enabled to so construct other parts of the plane as to allow the bit to be inserted and removed with great ease and convenience.

Another object is to provide a construction in which the frog is forced against the under side of the plane-iron in such a manner that it accommodates itself to the position of the plane-iron, thereby causing' an even distribution of pressure to be applied to prac* tically the entire surface of the plane-iron.

A further object is to provide a very simple, powerful and ready means for fastening and releasing the bit. For this purpose my newly invented plane has a handle which is pivoted to swing laterally, means are provided for holding the handle in fastening position, and further means are provided for adjusting the handle toward and from the bit to increase and decrease the pressure upon the bit.

Referring to the drawings :nlligure I is a perspective view of the plane constructed with my improvement. Fig. II is a broken view partially in section, taken longitudinally through the plane. Fig. III is a rear elevation of what is shown in Fig. II, omitting the handle. Fig. IV is a perspective of the frog. Fig. V is a fragmental plan, the handle being partly in section. F ig. VI isba reduced view showing the plane-irons, or (I it).

1 designates a stock which is provided with raised sides 2. The sides 2 are provided with oppositely arranged wings 3.

4 designates the holding-cap which is permanently secured to the stock as by being pivoted at 5 to the wings 3. That part of the lower surface of the holding-cap 4 which lies against the cap iron is perfectly ilat and provides an unobstructed smooth face against which the cap-iron may rest.

6 is a plane-iron which may carry a capiron 7.

8 is a frog which forms a bit support and is provided with oppositely arranged wings 9, which are provided at their lower parts with slots l0. Between the wings 9 isa bridge 11. The frog is a floating frog, that is to say, it is unattached, and can therefore adapt itself to make a perfect iiat contact with the plane of the underside of the pianeiron or bit which it helps to support.

12 is a handle which is carried by a rockbar 13; the ends of the rock-bar 13 are provided with pivots 14 and 1K5, which are mounted inlugs 16 and 17. The lugs 16 and 17 are preferably cast integral with. the stock and project upwardly therefrom. The lug 16 is provided with a screw 18, which bears against the end of the pivot 14. Projecting upwardly at an angle from the front end of the rocl -bar 13 is an arm 19, to the upper end of which is pivoted a roller 20.

l/Vhen the parts are assembled in proper position. the cap-iron 7 rests against the under surface of the holding-cap 41; the planeiron 6 resting against the under surface of the cap-iron 7 while the frog 8 bears against the under surface of the plane-iron 6. Projecting into the slots 10 of the frog are a pair of oppositely arranged lugs 21 which project from the opposite wings lWhen the handle 12 is in its norma vertical position, the arm 19 holds the roller 20 against the bridge 11, thereby pressing the frog tightly against the under side of the plane-iron and thus squeezing the plane-iron and cap-iron firmly between the frog and holding-cap.

1 have shown a double bit in the drawings composed of the plane-iron 6 and cap-iron 7 which are fastened together in the usual manner as shown in Fig. Vl. When it is desired to remove the bit, the handle 12 may be rocked to the left as shown in the dotted lines in Fig. lll., whereupon the arm 19 moves the roller 2O away from under the bridge 11 and allows the frog 8 to drop slightly, the slots 10 riding over the lugs 21. The frog being thus dropped away from the bit the latter may readily be withdrawn, the frog, cap-iron and attached parts remaining in the stock. r1`his avoids the necessity of slotting the bit entirely to the end or of entirely removing a screw to remove the bit as would be the case where vthe cap is removable, or the mechanism for adjusting the bit is below or to the rear of it. Upon replacing the bit, the handle 1.2 may again be rocked to the vertical position which causes the roller 2O to press against the bridge 11 and force the frog up against the under side of the bit thereby clamping the latter in position, the frog accommodating itself to the position taken by the holding-cap and bit. As the holding-cap is pivoted to the stock it is allowed to swing slightly; sufficiently to accommodate itself to the bit. The frog may likewise swing slightly for the same purpose, thus a perfect contact is made with both sides of the bit and the latter thus held from chattering or from slipping. The frog is connected to the frame by lugs 21, which latter guide the frog when released, and prevent it from jarring out of the plane. rEhe frog is unconnected, being perfectly free to swing to the plane of the underside of the bit and floats, as it were, above the roller 20. Of coui'se, when the frog has been forced tightly against the bit by the roller 20 it does not oat but its quality of floating or of being free to swing universally is that which enables it to make the flat, close fitting contact against the bit which is so desirable in rigidly holding the bit to prevent the bit from chattering when the-plane is in use, or to prevent the bit from creeping. The free action of the frog when not pressed tightly against the bit is obviously limited by the lugs 21 but its movement is not restricted to such an extent as to interfere with its proper function of adapting itself to the bit, as the frog has perfect freedom of movement within the restrictions, except at such times as it is forced tightly against thebit. This feature is regarded as of considerable importance and so far as l. am aware, l am the first to employ a frog which is perfectly free to adapt itself in all directions to the plane of the bit. lhile a pivoted frog will adapt itself to a certain degree, itis obvious that a. pivoted frog is limited to the radius of its fulcrum, but the frog which l employ is absolutely free.

ln order to hold the handle 12 in a vertical position, l have provided a button 22 which is pivoted to the stock and the lip of the button may lie fiat over a lug 23 which projects laterally from the rear end of the rockbar 13. By adjusting the screw 18, the rock-bar 13 may b'e adjusted longitudinally .on the stock, so as to produce the requisite between the roller 20 and degree of pressure the handle is swung into bridge 11, when fastening position. bar 13 a strong pressure is produced against the frog, while by retracting the rock-bar 13, the pressure upon the frog is reduced. For adjusting the bit to secure the proper cut, l have provided a bell-crank lever 24, which is pivoted at 25 to the holding-cap 4. of the bell-crank by means of a slot in the'cap-iron 7 `as at 26. Where a single bit is employed the slot will be formed in the plane-iron 6. the slot may be in both plane-iron iron of the double bit.

27 is an adjusting screw mounted upon the cap 4 and provided with flanges 2S, between which flanges the other end of the bell-crank and caplever 24 lies. By moving the screw 27 in or out, the lever 24 is rocked, and the bit thereby moved longitudinally into the proper position, the plane-iron projecting below thc bottom of the stock the distance desired.

lt will be seen that the irons are very securely held and yet adapted to be quickly removed, as it takes but an instant to throw the button 22 and tilt the handle 12, to loosen the frog, so that the bit may be withdrawn. The bit may facility as there are no eXtra pieces to be inserted and fitted into the stock, and when the bit is in place the handlemay quickly be rocked to clamp the parts. 1f desired, the frog may be removed as the slots 10 are open By advancing the roel:-

One end lever engages with the bit Y lf desired K be inserted with equal I at the bottom, although its removal is not necessary when removing the bit.

ln order to give the proper set to the bit, l have provided a setflever 29 which lies in a recess a in the holding-cap 4 and which is pivoted thereto, as at 30; the lower end of the set-lever being provided with a lug 31 which projects into a slot 32 in the cap-iron of the bit. By adjusting the set-lever 29 at the proper' angle, the lug 31 bearing in the slot in the cap-iron causes the cap-iron to be shifted to the properI angle, and also the plane-iron with it. lt will be seen that the handle is pivoted to rock laterally of the stock, thus the strains upon the handle which are produced when the plane is used do not tend to rock the handle or endanger the accidental loosening of the frog. ,By mounting both the set-lever 29 and the bellcrank lever 24 upon the holding-cap both of these adjustments are in a prominent position where they are easily accessible and in such a position that a good linger grip may be applied to the screw 27 as well as to the set-lever 29. These two adjustments being both mounted on a single piece obviates any liability of their becoming shifted from their relative operative positions and insures a reliability of adjustment which is of especial importance. lt will be noticed that the roller 2O applies pressure, through the inediuin of the frog, at a point above the pivotal support 5 of the holding-cap which acts as a fulcrum and results in forcing the lower edge 8al of the frog against the back edge of the throat.

l do not desire to limit myself to the specific construction herein shown and described, as it is obvious that many variations and changes may be made in the einbodinient herein set forth without departing from the spirit of my invention.
