SPECIFICATION forming part of Letters Patent No. 553,988, dated February 4, 1896. Application filed June 4, 1894. Renewed August 19, 1895. Serial No. 559,807. (No model.)

To all whom it may concern.-

Be it known that we, THOMAS TINSLEY HEATH, of Loveland, Olermont county, and ALOIS NICHOLAS VERDIN, of Glendale, Hamilton county, Ohio, have invented certain new and useful Improvements in Multiple Profiling-Machines, of which the following is a specification.

This invention pertains to machines designed primarily for the cutting of metal type or die-sinker punches, but is useful for other work of a similar character.

Our improvements Will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of a machine exemplifying our invention, portions appearing in vertical longitudinal section; Fig. 2, an end elevation of the same, corresponding with the left-hand end of Fig. 1; Fig. 3, a plan of the machine; Fig. 4, a vertical transverse section 'of the machine, showing the guide employed when a flat groundwork is to be produced; and Fig. 5, a plan and horizontal section of portions of the machine, showing the guides for securing flat groundwork.

In the drawings, ignoring Figs. 4 and 5 entirely for the present, 1 indicates a long horizontal bed; 2, a series of universal bearings mounted thereon in a line at right angles to the length of the bed and in a'common horizontal plane; 3, -a rod universally journaled in each of these bearings, the rods projecting a short distance to the front and a much greater distance to the rear of their bearings; 4, a blank-holding chuck on the front end of each of the rods 3, these chucks being adapted to receive the blanks on which the letten cutting is to be done; 5, the blanks held in these chucks and presenting to the left the ends 011 which the letter-cutting is to be done; (3, a tailward prolongation of one of the rods 3, this prolonged rod being preferably adj ustable in length; 7, a bar pivoted to the tail end of all of the rods 3 and equal distances from theuniversal bearings 2, the distance between the pivots which unitebar 7 to the rods 3 corresponding with the distance between the center of the universal bearings 52, so that a parallel coincident movement is produced upon all the bars if any one be rocked in any way in its universal bearing; 8, a tail stock secured to the bed beyond the tail-end of the rod 6; 9, a templet-holdin g chuck upon the tail end of rod 6, this chuck being adapted to receive a contour templet corresponding, but on a much enlarged scale, with the letter to be out upon the ends of theblanks 5; 10, the templet secured in the chuck 9; 11, a handle on chuck-rod 6, near its tail end, by means of which the rod can be rocked; 12, a guide-pin supported by the tail-stock 8 and having its forward cylindrical end engaging the contour of the templet 10; 13, a headblock mounted to slide horizontally on the head of the bed to and from the chucks 4; 14, a screw mounted on the bed and engaging this head-block and adapted to adjust the head-block to and from the chucks 4, this screw ext-ending tailward to the tail-stock; 15, a pointer and handle on screw 14 at the tail-stock, by means of which the screw may be turned 16, a graduated dial for indicating the degree of turning which has been given to the screw 14; 17, a series of head-stocks mounted upon the head-block 13 and arranged for sliding motion therein to and from the chucks 4, there being one of these head-stocks for each of the chucks 4 and correspondingly spaced; 18, a cutter-arbor in each head-stock; 19, a cutter in each of the arbors, each presenting its point to the appropriate one of theblanks 5, the axes of theuniversal bearings 2 being in the lines of the axes of the cutterrarbors, and 20 a screw for each of the head-stocks 17, by means of which those headstocks can be independently adjusted upon the head-block 13 to and from their chucks 4. Assume the templet 10 to have the form of the letter to be out upon the blanks, but enlarged ten times over the size of the letter to be cut. Let the length of rod 6 be adjusted, so that as the rod system is oscillated the face of the templet will have a movement ten times as great as that of the faces of theblanks 5. Assume cutters 19 to be square tapering milling-cutters fora cross-dimension adapted to produce the internal angles to be cut in producin g the type when the cutters have a given depth of working. Let the end of guide-pin 12 which engages templet 10 have a diameter equal to ten times that of a working diameter of the cutters at the faces of the blank when working at the given depth.Blanks 5, with their outer ends truly faced, are to be put into the chucks 4, with their faces in a common vertical plane when rod b is in a common axial line with guide-pin l2.Screws 20 are then to be adjusted to bring the points of the cutters even with the faces of the blanks. Rod 6 is then to be swung till the blanks clear the cutters sidewise. Screw li is then to be turned to draw all the cutters simultaneously toward the blanks a distance equal to the given depth of working.Handle 11 is then to be manipulated to cause the margin of the templet to follow the end of the guide-pin, the result being that the cutters reproduce upon a scale of one-tenth the form of the templet upon the blanks, all of the blanks being cut simultaneously. Handle 15 is then manipulated to withdraw the cutters to a second given depth of cutting, thus appropriately lessening the working diameters of the cutters at the face of the blank, and a second guide-pin 12 is then substituted, the new guide-pin having a working diameter appropriately corresponding with the new working diameter of the cutter at the face of the blank. The templet is again caused to follow the guide-pin, thus producing upon the blanks a further cutting with a cutter of smaller working diameter and better adapted for the keener angles and finer curves of the letter. The cutter is again further withdrawn and a still smaller guide-pin substituted until the work is done. The cut blanks are then removed and their faces polished, which finishes them.

It will be obvious that the groundwork produced bythe cutting operation described will be spherical. This is entirely satisfactory for ordinary sizes of printers type, but for very large sizes a flat ground might be desirable. In such case the guiding arrangement shown in Figs. 4c and 5 may be employed. Thechucks 5 in such case are mounted on across-head 23, which slides horizontally in a Vertically-sliding eross-head 22, guided in aframe 21, secured to the bed-plate, the universal motion which the chucks are thus eapable of making in a true vertical plane being given by chuck-rod 6 through the me- I dium of universal connection 2i. The movement of the templet in the previously-described arrangement is also spherical, and for extremely large letter cutting, it may sometimes be desirable to cause the templet also to move in a true plane, which may be done by mounting the templet-chuck 9 on a universally-guided cross-head, as in Fig. 5.

Ive claim as our invention- 1. In a profiling-machine, the combination, substantially as set forth. of a universallynected with one end of said rod, a rigidly-supported guide-pin presenting its end to said templetchuck, a series of blank-chucks connected with the other end of said chuck-rod and adapted to receive simultaneous and coincident motion therefrom, a series of cutters presenting their points to said blank-chucks, means for adjusting said cutters simultaneously toward said blank-chucks, and a screw for each of said cutters for adjusting them independently toward their respective blankchucks.

In a profiling-machine, the combination, substantially as set forth, of a series of universal bearings, a rod journaled in each of said bearings, a blank-chuck upon one end of each of said rods, a bar pivoted to all of said rods and holding them parallel, a chuck-rod in prolongation of one of the previously-mentioned rods, a templet-chuck car ied by said prolonged chuck -rod, a rigidly-supported guide-pin presenting itself to said templetchuck, a series of cutters presenting their points to said blank-chucks, and means for adjusting the distance between said cutters and blank-chucks.
