JOEL LUND, OF SAN FRANCISCO, CALIFORNIA.

BENCH-PLANE.

Application filed March 12, 1908.

To all whom it may concern:

Be it known that I, JOEL LUND, a citizen of the United States, residing at San Francisco, in the-county of San Francisco and State of California, have invented a new and useful Bench-Plane, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a bench plane of the combination wood and iron type, and its object is to make such a plane as will be adjustable with the least difficulty, and which may be cleaned of any shavings that it may happen to collect with the least trouble. The plane might be made entirely of iron, if so desired.

Another object of the invention is to provide means for adjusting the bit of the plane at any point and yet to allow the bit to be worn as much as possible in order that it may be sharpened whenever it may be necessary.

Another object of the invention is to provide means to adjust the bit cap without ren'ioving the bit from the plane.

Another object of the invention is to so place the adjusting means as to be out of the way and in the most handy position for use.

Another object of the invention is to arrange the means for adjusting the bit cap in such a manner as to enable the carpenter to tell at a glance just how high the bit cap is above the bottom of the plane, thus making it easy for him to adjust the cap as may be necessary to correspond with the work he is doing.

Another object of the invention is to give the benefit of the iron construction to those parts of the plane which it is necessary should fit closely and smoothly, and yet not make the quantity of iron in the plane large enough to increase the weight of it to such a point as to make the plane unduly heavy.

In the drawing, Figure 1 is a sectional view of the entire plane, the plane of section being the central longitudinal, Fig. 2 is a plan view of the iron parts of the plane, Fig. 3 is a sectional view on the line 3 Fig. 1, Fig. at is a sectional view on line 1 of Fig. 1, Fig. 5 is a sectional view on line 5 of Fig. 1, Fig. 6 is a sectional view on line 6 of Fig. 1, F 7 is a plan of the lower endof the bit cap with a part of the holder in section, Fig. 8 is a perspective view of the Specification of Letters Patent.

frame, Fig. 9 is a perspective view of the bit cap, Fig. 10 is a plan view of the bitcap holder, and Fig. 11 is a perspective view of the bit cap holder, both views being on a larger scale than that of Fig. 1.

The numeral 1 represents the wooden block which forms the body of the plane, 2 being the handle of the plane, and 3 a knob at the front end of the plane by which the person using the same is enabled to have a better hold of the front end of the plane than is possible where the block is not provided with such a knob. This block has the throat 41- cut through it and in which are secured the parts that make up the active members of the cutting device.

The iron parts to which the bit is secured are made complete and separate from the body of the plane, a pair of screws and 6 being used to hold the iron parts to the body.

The main casting or frame of the plane is shown at 7. It is provided with openings and lugs as follows: At the bottom is the transverse slot 8 through which the bit proj ects, in front of this slot are two holes 9 in alinement transversely and just above the slot through which the bit projects. In the rear of the slot 8 there is a downwardly projecting lug 10 which is slotted for the reception of the adjusting screw, this screw having neck which is pushed up into the slot when the parts are assembled. In the center of the body of the casting 7 there is a slot 11 which opens through the casting. This opening 11 in the frame 7 is for the purpose of allowing the reciprocation of the part 35 of the bit adjusting bar 3 1, said bar moving in a shallow groove in the under side of the frame 7 at its lower end when the bit becomes worn. At the sides of this groove are the holes 12', 12 through which the screws 5 and 6 pass to hold the frame to the wood body 1. Under the slot 11 and near the top of the same there is a rib 13 which has a hole 14t therein, the hole being so shaped as to allow the adjusting screw considerable play when the same is inserted in its place, since it must carry an adjusting wheel.

Above and to the rear of the rib 13 there' is another rib in which are the large hole 15 and small hole, the .former being large enough to allow the adjusting wheel on the bit adjusting milled head 30 to pass through, and the small hole is for the reception of a small pin 16 to hold the said milled head 30 in its place.

The bit cap holder 17 is provided with a pair of holes 18 in its side flanges which correspond with the holes 9 in the frame and which, when in place receive a pin 19. This holder is provided with a beveled portion 20 at each side thereof and near the slot of the frame through which the bit projects. Just above each beveled part 20 there is a slot 21, and a little farther up near the center there is a slot 22 through which the set screw that holds the bit in any given position passes. Just above the slot 22 there is an upwardly extending lug 23 which has an open slot cut in it to receive the neck of the cap adjusting screw. Near the top of the cap holder there is a transverse slot 24 through which the bit adjusting lever 25 passes, said lever being pivoted to the frame and having a downwardly projecting pin 26 for moving the edge of the bit to compensate for uneven grinding when the same is sharpened. At the top of the cap holder there is a heavy spring 27 which holds the holder down to the frame when the same is in use. The bit adjusting screw 28 has a small bevel wheel 29 which meshes with alike small wheel carried by the thumb nut 30, said thumb nut shank having a groove around it for the reception of a pin 31 which holds the thumb nut in its place in the frame. The adjusting screw 28 is put into place from the top of the frame and is then pushed up into the slot of the lug 10, the head 32 holding the screw in a fixed position with relation to the frame. This screw 28 passes through a downwardly projecting lug on the bit adjusting bar 34:, said bar having an upwardly projecting lug 85 which takes in a slot in the top of the bit, thus allowing the bit to be moved longitudinally by turning the thumb screw in front of the handle.

The bit cap and adjusting parts are all secured to the bit cap holder independent of the frame and plane stock, the cap holder being hinged so that it can be raised up far enough to permit the removal of the bit, the movement being through a considerable angle. This is accomplished by having the center of movement of the hinge far enough in front of and above the point at which the front end of the bit cap bears on the bit, so the motion of all parts of the bit cap is away from the bit.

The bit cap 36 has a lug 37 on each side thereof which takes in the slots in the side of the cap holder, and it has a threaded hole at the top which extends longitudinally thereof for the reception of the small adjusting screw 38. In front of this hole there is another hole 39 which permits the upstanding lug 23 to pass through, and it is large enough to allow the cap to move longitudinally enough to compensate for any wear, should it be necessary to grind the cap at any time, or should it be necessary to move 'top of the cap holder.

the cap, as in the case where fine work is to be done and then where coarser work is to be done. In front of the square hole 39 in the cap there is another threaded hole 40 which the thumb bolt tl passes through, said thumb bolt having a washer on its end of greater diameter than the width of the long slot cut in the bit and through which the pin of the side motion adjustment lever passes. At the lower end the bit cap is beveled in three places, on the bottom, and on each edge just above the bottom. The purpose of this is to give perfectly smooth surfaces for the shavings to pass up over, since the cap is of the full width of the opening through the main frame below the beveled portion of the cap holder, this being accomplished by providing the cap with two lugs at the bottom, the two upper lugs passing through the cap holder slots 21.

Now it will be noted that when the cap holder is down on the frame that the cap will be tight on the bit at the lower end only, or it may not be tight there, but by tightening the thumb nut in the cap holder and which is threaded into the cap the lower end of the cap may be made as tight as necessary, up to the strength of the spring catch at the As illustrated the movable parts of the plane are all secured to the frame and it might be sold separate from the block. 7

In operation it is often necessary to take the bit out of a plane to free it from shavings that may get caught therein and with this plane this may be done without any difficulty and without in any way interfering with the adjustment of the bit, since all the adjustments are not in any way changed by lifting up the cap holder. It is also an advantage to have the bit cap free from the bit for the reason that it leaves the bit free to be taken out of the plane to be sharpened, while the relative position of the cap remains just the same as it was previously and may be adjusted at the will of the user, lines being provided on the cap to show its relative position with respect to the bottom of the plane block.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows:
