PLANE.
HEECIFICATION forming part of Letters Patent No. 334,943, dated January 26,1886.
Application filed November 11, 1885. Serial No. 182,435. (No model.)
To aZZ whom it may concern:
Be it known that I, AUGUsT DOLL, a citizen of the United States, residing at Lena, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Planes, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to improvements in planes, and is designed to produce a device for adjusting and removing the bit, that shall be readily attachable to the body of an ordinary plane.
In the drawings, Figure 1 represents a longitudinal section of a portion of a plane-body with the improved device attached thereto; Fig. 2, detail views of the wedge-operating 1ever; Fig. 3, a detail showing the bed-block for the bit-operating screw; Fig. 4, details of the bit-operating screws, and Fig. 5 a modified form of connection between the wedge and its operating-lever.
The plane-body A has a recess, B, for the bit 0 and a portion of the mechanism.
The bed-plate D of the bit-adjusting mechanism is a frame consisting of a plate with triangular end wings, and rests on the body to the rear of the bit 0, and is secured to said body by screws or otherwise. This bed-piece D has a central threaded passage for the screw E, which is provided with a head with an annular recess or groove, F, Fig. 4:. In this groove engages an arm of an L-casting,G, the other arm of which carries a screw-rod, H, passing through the bit 0 near the top thereof, and clamped to the same by a thumb-nut, I. The casting G being secured to the bit and to the screw E, when the latter is turned, it must necessarily carry the said bit up or down, and thus presents an easy means of adjust ment for the same. By boringahole through the said bit and screwing the bed-piece in place, the attachment is secured to any plane, and in working order.
Extending across the recess B, just in front of the wedge K, is the fulcrum or pivot-rod L of the lever M, which is provided at its upper end with an extension, N, carrying a thumb-screw, 0, bearing normally on the top of the said wedge K. Just below the position of the rod L, the wedge is provided with a series of notches, P, or a single notch, as shown in Fig. 5. In these notches is adapted to engage a spur or tongue, R, forming the shorter arm of the lever M. The space between the rod L and the bit 0 being constant, as the wedge K is forced between them by the screw 0, the said wedge must act to clamp the said bit in place. By loosening the screw 0 and throwing the lever M forward, the spur R will catch in the notches or notch P and move the wedge K upward, thus releasing the bit from pressure and allowing its adjustment, as stated.
In order to prevent wear, the notches are cut in a plate set in the wedge; or the lower edge of a plate is used, as in Fig. 5..-
I claim 1. In a plane, a wedge provided with one or more notches, a lever fulcrumed in front of said wedge, and provided with a spur or tongue for engaging said notches, and an adjusting-screw normally engaging the top of said wedge, and seated in the upper end of said lever, substantially as specified.
2. In a plane, an adjusting device consisting of a'clamp-piece secured to the bit, and a screw having a seat secured to the body of the said plane and engaging said clamp-piece, combined with a bit-clamping device consisting of a wedge with a notch or notches on it, a lever fulcrumed in front of saidwedge and having a spur or tongue engaging said notches, and an adjusting-screw seated in the top of said lever, and engaging with the upper end of said wedge substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
AUGUST DOLL.
