HENRY WAAS, OF SAN FRANCISCO, CALIFORNIA.
SUNG-CUTTER.
SPECIFICATION forming part of Letters Patent No 314,086, dated March 17, 1885. Application filed November 7, 1881. (No model) To all whom it may concern:
Be it known that I, HENRY WAAS, a citizen of the United States,residing atSan Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Bung Cutters, of which the following is a specification.
My invention relates to a self-centering ex pansive hollow Aauger or bung-cutting tool having a series of cutting teeth or bits arranged in a circular manner around and se-y cured to a rotary mandrel,said tool being provided with means for regulating the diameter and the degree of taper to` be given to the bung.
Figure l is a perspective view illustrating my improved bung-cutter. Fig. 2 is a central vertical sectional view of the same. Fig. 3 is a plan view of the disk, and Fig. 4: is a plan view of the small end of the mandrel.
Similar letters of reference are used to indicate like parts throughout the several figures.
A represents the mandrel, the upper portion or half of which is made of less diameter than the lower part, and is providedwith a series of slots or mortises, B, extending in a line parallel with the axial line of the inandrel and are open at their upper end. Within these slots I place the lower ends of the cutters C, which are held therein by the setscrews D, carried by the band or collar E, which surrounds the upper portion of the mandrel. V
Any desired number .of cutting teeth or bits may be employed, and their outer, upper, or forward ends are braced and steadied by resting within the notchesor mortises F made in the disk G. The disk G is rigidly secured upon the spindle or rod H by means of a set` screw, G', Fig. 3, and has projecting from its upper face a short 'pin or point, I.
The spindle H passes completely through the mandrel,and is provided with a laterallyextending guide-pin, J, which engages with the slot K, cut in the lower or thickest part of the mandrel, and by this means the spindle is made rigid with the mandrel relative to axial rotation, while at the same time the said spindle is permitted to have a certain amount of play or movement forward and back, or in and out of the mandrel, the amount of such play being limited by the length of the slot K.
Around the lower end or portion of the spindle is loosely wrapped the coiled spring L, the forward end of which rests or presses against the guide-pin J, while the inner end presses against the metal of the boring-ma chine into which the mandrel is fitted and from which it receives its rotating motion.
The mortises or open-ended slots B may be made of any desired depth, but a depth equal to about one-third of the radius of the mandrel will be found most suitable, and the diameter of the bung or plug to be cut may be regulated by theinsertion of splints or wedges M, which are placed within the slots between the face thereof and the cutter, as shown in Fig. 2. When bungs of the smallest size are to be made, the cutters are laid up dat against the face of the slot and the splints placed upon the outside, in which position they are rigidly held by the set-screws D, hereinbefore referred to.
The mortised disk G at the forward or outer end of the spindle may be removed at pleasure and another of a different size substituted for it for the purpose of regulating the spread of the cutters for cutting either a larger or a smaller bungl or plug than the standard size.
Theoperation of myimproved bung'cutter will be as follows, to wit: The tool having been properly placed in the boring-machine, and the blank from which the bung is to be cut placed upon its supporting or base block, the tool is brought down and the point or pin I placed at the center of the bung about to be cut. The tool is now caused to rotate, and the downward pressure upon the tool being continued the bung or plug is cut, cored, or reamed out. As the cutters advance or cut their way through the wood, the disk G remains in contact with the wood, or in its original position, while the cutters are forced down through the mortises F, and as the diametrical distance between the mortisesF in the disk G is greater than the distance between the mortises B in the mandrel A it will be readily seen that the closer the disk approaches the mandrel the farther apart will the points` of the cutters be spread, thereby enlarging the circle of their cutting operation and givin@ the required taper to the bung. As the cutters and man- IOO drel advance upon the spindle H the coiled spring L is compressed; but as soon as the bung is cut the expansive power ofthe spring will force the rod and disk back to its original position with reference to the mandrel and cutters and iorce out the core which constitutes the bung or'plug` from between the cutters,and the tool will be ready for a repetition of the operation.
By this construction I am enabled to provide a cutting` or boring tool which will automatically perform or accomplish the cutting out of the bung and give to it the requisite rmount of taper, while at the same time the tool is kept centered in its original position.
Having thus described my invention,I claim and desire to secure by Letters Patent In a bung-cutting tool, the combination o'f `have hereunto set my hand and seal.
