IMPROVEMENT IN DIE- GRIN DI N G MAC H IN ESL.
Specification forming part of Letters Patent No. 196,183, dated October 16, 1877 application filed May 2, 1877.
To all whom it may concern:
Be it known that 1, J. A. BIDWELL, of Cleve land, in the county of Ouyahoga and State of Ohio,have invented anew and useful Improvement in Machines for Grinding Dies and Outters for Tack and Nail Machines; and I do hereby declare that the following is a full, clear,
and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a side elevation of my improved grinding-machine. Fig. 2 is a front elevation of the same. 3 is a plan view of the same. Fig. 4 is a sectional detail, taken 011 the line 00 00 of 1, and illustrating the operation of grinding the groove for the nail-shank of one of the halved dies. Fig. 5 is a sectional detail, taken on the line y y of Fig. 1, and illustratin g the operation of grinding the groove for the nail-shank of the other halved die. Fig. 6 is an elevation of the grinding'wheel used for making said grooves. Fig. 7 illustrates the operation of grinding the knives used for cutting the blanks, the parts being shown in elvation. Fig. 8 illustrates the same operation by showing the parts in plan view. Fig. 9 is an elevation of the wheel used for the grinding of the knives and the joints of the dies, shown in the act of grinding one of the dies.
The nature of my invention consists in certain constructions, combinations, and arrangements of parts, hereinafter fully described and specifically claimed, whereby a machine is produced upon which dies and cutters of nail-machines are adjusted in their exact position and afterward moved toward suitable revolving grinding-wheels to receive their proper shape. In the drawings, A represents a stand, which may be of metal, and supports a lathe-head, B, with a spindle, O. This spindle O is driven by means of a cone-pulley, c, and a belt from the line-shafting of the shop wherein the machine is used. The front end of the spindle O is of greater length than usual, and has the conical shank (Z of a grinding-wheel spindle, D, fitted into it in the same manner as lathe-centers are fitted into the spindles. A hole, 0, is so drilled through the spindle G that its center falls into the end surface of the spindle D, so that it may be forced out of the spindle O by means of a drift. Below the lathe-head a vertically-slid ing elbowplate, E, is, by meansof an ordinary dovetail fit, attached to an extension, A, of the stand A. A set-screw, c, in the plate E, bearing with its joint upon the extension A, serves to fasten the plateE at any altitude desired. A plate, F, is, by means of a horizontal dovetail fitting, attached to the horizontal part of the plate E, and is thereby adapted to slide from or toward the stand A. A set-screw, f, bearing with its point upon the plate F, and being, inserted in the plate E, serves to fasten the plate F in any desired position upon the plate E. A plate, G, is fitted, by means of dovetail, upon the plate F, so that it may be moved horizontally and at a right angle to the direction in which the plate F slides. A setscrew, g, in the plate G serves to fasten the permits the swinging of the plate at diiferent angles toward the grinding-wheel.
The plate H is steadied in the required posi tion by means of a slotted brace, I, pivoted, at 1', to the side of the plate H, and fastened by a set-screw, i, to a lug, g, on the plate G, as plainly seen in Fig. 2. The lug G is extended toward the lathe-head, and at a small distance from the plate His provided with two lateral steps, J J, with vertical sides. The step J is provided with a horizontal set sorew, j, near its top, and the step J with a similar set-screw near its bottom. The said steps serve as guides for the dies K, to be ground, and, as the grooves 70 for forming the nailshanks must be tapered the dies must be moved under the grinding-wheel D in an inclined position, which latter is accomplished by moving the set-screws jj beyond the surfaces of the steps J J, and pressing the dies K K with the finger against the steps and the points of the set-screws, as indicated by arrows in Figs. 4 and 5. By means of this arrangement the set-screws may remain unchanged for a long time, and a great number of right and left dies may be made with perfectly similar grooves.
The rectangular joints of the dies K K are ground by a wheel, D with a cylindrical surface, as shown in Fig. 9. For this purpose the set sorews jj must be withdrawn from thesun feces of the steps- J J, so thetthe diesean be held in at "vertical position by the finger of the opera-tor.
