UNITED STATES PATENT OFFICE.
JAMES M. CLARK, OF JERSEY CITY, NEW JERSEY.
IMPROVEMENNTIN THE MANUFACTUREOF RNAMENTAL TUBING.`
Speccation forming part of Letters Patent No. 174,117., dated February 29, 1876; application tiled February 3, 1876.
. To all whom it may concern:
Be it known that I, JAMES M. CLARK, of Jersey City, in the county of Hudson and State ot' New Jersey, have invented an Improvenient in the Manufacture of Ornamental Tubing, of which the following is a specification:
Ornamental tubing for pencil-cases has been made with grooves and ribs similar to a three, four, orv more threaded screw, and this orna- -1nentati`on has been done by a draw-plate die properly shaped, and ra spiral or twist mandrel upon which the tubeihas been placed.
Tubes and pencil cases have been ornamented by an engraved figure put upon 'the same byan engraving-engine, such tigure being composed of ranges of diamond forms in -relie This operation is tedious andexpen sivefor labor, and can only be done upon a case that issufticiently thick 5 hence with gold and silver such cases are costly.
By my improvement I am enabled to employ very thin sheet metal, and render the tube stiffer than a plain tube, and at the saine time to ornament the tube in a much less time than by engraving, 4without loss of material, and to produce a series of quadrangular or dia-- `making the ornamentations upon the tube.
One die, a, is provided with ribs and grooves upon its inner tapering surface that incline to the axis in one direction, and the other die, b,
is'made with ribs and grooves upon its inner tapering surface,inclining in the opposite direction. These grooves are preferably made by a tapering punch, such as shown in Fig. 5, which punch is pressed into the die while the latter isin asoft condition. The die is also to be tiled up, and the edges properly rounded. The punch for the second die is similar, but
the angle of the inclination of the grooves is the reverse.
The thin sheet-metal tube is inserted through this die a upon the draw bench, and pulled through such die. Either the tube or the die `must be allowed to .revolve in consequence ofthe screw form ofthe grooves. This operation iinparts to the tube the form shown in'Fig. 2, and it is to be understood that a tube in the form shown in Fig. 2 has before been made, and l do not claim the same.
Thetube is to be run through the second draw-plate die b, in which the grooves stand at the opposite angle, the result of' which `is that the first ribs are crossed by a second set ot' grooves that divide such ribs into quadrangular or diainondshaped projections, producing a tigure somewhat similar to the figure known as the barley-corn77 in engine-engraved work, but the figure is bent iu the thin sheet metal instead of being engraved. The bending operation will be most perfect after the tube has been passed through theiirstdie as a third operation, and then again through the second dies, asa fourth opera-tion, or else two other dies similar to the trst and second, but slgh tly smaller,inay beemployed for the third and fourth operations.
The grooves and ribs may be rounding sectionally, or with angular faces, according to the shape of the barely-corn projections to be formed.
I claim as my in ventionl 1. The method herein specified, of ornamentin g tubing, by drawing the saine successively through two dies grooved spirally in op-f posite directions, substantially as set forth.,` 2. The ornamental tubing with the quadrangular or barley-corn projections, bent in the thin metal of such tubing, as a new article of manufacture. Signed by me this 1st day February, A.D. 1876.
JAS. M. CLARK.
