WILLIAM E. SENNETT, 0F BALTIMORE, MARYLAND.
DIE-UFSETTING DEVICE.
To all whom it may concern:
Be it known that 1, WILLIAM E. SENNETT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Die-Upsetting Devices, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to tool dressing machines, and it more particularly relates to an improved lathe attachment designed for upsetting the cutting edges of compound dies.
It is well known, to those who are familiar with the art of punching metal sheets, that after the punching dies have been used for a considerable length of time, the cutting edges become dubbed off, so that the di ameter of the punching die or tool is decreased at the cutting edge to such an extent that it is necessary to increase the diameter of said cutting edge by swaging the adjacent metal outward. This process has been accomplished heretofore by hand, by hammering and this process is not only tedious but inaccurate.
Therefore an object of this invention is to provide a strong and rigid attachment for an engine lathe whereby these compound dies may be swaged or upset quickly and accurately Another object of the invention is to provide a device of this character which is of simple construction, compact, easily applied to lathes of ordinary construction and thoroughly practical and eflicient in operation.
Other objects and advantages may be recited hereinafter and in the claims.
In the accompanying drawings, which supplement this specification, Figure 1 is a side elevational view of my improved lathe attachment and tool upsetting device; Fig. 2 is an enlarged fragmental view illustrating the relative positions of the upsetting and closing rollers, and their relation to the tool being operated upon; Fig. 3 is another enlarged fragmental view illustrating the upsetting and closing rollers in a position at right angles to Fig. 2; Fig. 4 is an end elevation view of the main frame or body of the device; Fig. 5 is an enlarged sectional view in the plane of the axis of one of the punching tools upon which this device is designed to operate; Fig. 6 is a fragmental view of the tool, illustrating in a somewhat exaggerated manner the cutting edge of the Specification of Letters Patent.

Serial No. 778,721.
punching tool after considerable use and before being upset; and Fig. 7 is a view similar to Fig. 6 of the tool after it has been upset and before it has been dressed.
Referring to these drawings, in which similar reference characters correspond with similar parts throughout the several views, the body or frame 5 of the device is provided with apertures 6 through which bolts or other suitable anchoring means may be passed for securing the frame to a lathe bed. This frame may be cast or forged from suitable metal, and is provided with a central opening 7 and with side openings or guide ways 8 which communicate with said central opening. Adjacent to the side openings is a pair of flanges 9 and 9 which extend upward and downward respectively, to prevent disengagement of the carriages 10 which are slidably seated in said side openings and carry the closing rollers 11 and upsetting rollers 12. Each of the bars or carriages 10 carries two rollers 11 and one roller 12, the latter being of frusto-conical shape, while the rollers 11 are preferably of oblate-spheroidal shape. The bars 10 are each preferably slotted at 13 and 14, and apertured at 15 and 16, these apertures communicating with the respective slots, and being screwthreaded for the reception of screws or pivots 18 and 19 respectively on which the respective wheels 11 and 12 are journaled. Each bar 10 is also apertured and screwthreaded at 20, these apertures extending longitudinally through ribs 21, one of which is formed on each bar 10. One rib 21 is provided with a right hand screw thread, while the other is provided with a left hand screw thread, so that the two bars may be connected by means of a screw member 22 which is provided with an enlargement 23 at its middle portion and has a right hand screw thread extending from one side of said enlargement, and a left hand screw thread extending from the other side of said enlargement. This screw member 22 is fitted within the screw threaded apertures 20, so that by rotating it in one direction, the carriages 10 are brought into proximal relation,
while by rotating said screw member in the opposite direction, the members 10 are separated. The screw member is provided with a squared end 24;, for receiving a suitable wrench, for turning the screw.
In applying the device, it may be either secured to the carriage of the lathe, or
mounted upon the ways thereof in contiguity with the carriage, so that it mayv be advanced in the direction of the tool A to be operated upon, said tool being chucked in the lathe. The lathe is now started'so that the tool rotates against the rollers 11 and 12, and by its frictional contact therewith causes them to rotate.
and at the same time, the screw member 22 may be operated for pressing the surface inward adjacent to said beveled surface. It
i I will be seen that the cutting edge will be increased in diameter while the adjacent portion of the die will be decreased in diameter, thereby imparting the desired flare to Hsaid punching tool, preparatory to dressing the same for use.
From the foregoing, it will be seen that I .have provided a device of this character which is fullyrcapable of attaining the foregoing objects in a thoroughly practical and effective manner.
I do, not limit my invention to the exact.
. details of construction,combination and arrangement of parts, as herewith illustrated and described, but my invention may only be limited by a reasonable interpretation of The lathe is now operated for pressing the rollers 12 frame adapted to be movably secured to a other, a frusto-conical roller carried by each carriage, and a second roller carried by each carriage contiguous and axially perpendicu- 4E lar to the axis of the first said roller.
2. A device of the character described comprising a frame provided with an opening, a carriage mounted on the frame adjacent each side of the opening, means for moving the carriages one relatively to the other, and a plurality of rollers carried by each carriage, the aXis of the rollers being angularly disposed one relatively to the other.
3. A device of the character describedineluding a frame having. an opening, a carriage mounted on the frame adjacent opposite sides of the opening, a plurality of relative angularly disposed-rollers carried by each of the carriages, and means common to both of the carriages for imparting relative movement thereto,
In testimony whereof I hereunto aflix no signature in thepresence of two witnesses.
